This invention relates to ironing machines, and has to do .with domestic ironing machines intended for home use.

In patent No. 2,346,374, issued April 11, 1944, to Frederick M. Freis, there is disclosed an ironing machine in which the motor is housed within the roll and drives the latter, while also operating the shoe for moving it to and from the roll, which is supported for rotation on a bracket structure secured to the gear housing. The instant invention is directed to an ironing machine having the motor housed within the roll and efiectlve for driving the latter and for operating the shoe, the motor also serving as part of the means for supporting the roll. Also, I take advantage oi the positioning of the motor within the roll for drawing air through the padding of the roll so as to avoid excessive dampness thereof, thereby assuring that articles being ironed are properly dried in passing through the machine, which is conducive to increased speed in ironing. An additional feature of my invention is the provision of shoe coupling and release means operable from in front of the machine, adapting it for use with a cover having a rearward shoe enclosing section normally stationary on the stand or supporting structure of the machine.

I also provide improved means for driving the roll and operating the shoe from the motor housed within the roll, directed to simplification of construotion and reduction in the number of parts employed. Further objects and advantages of my invention will appear from the detail description.

I have illustrated my invention, by way of example, as embodied in an ironing machine comprising a support or stand 20 having a top plate 2| of channel section both lengthwise and transversely, with end frames or legs 22, of suitable construction, rigidly secured to and extending downward from plate 2! at each end thereof. A gear housing 22 extends upward from plate 2| at one end-the right end'as viewed in Figure 1-thereoi, the lower portion of housing 23 extending downward through plate 2! between reiniorcing angle members 24 and 24', spot welded to the underiace of plate 2|, to which it is bolted (Figures 2, 3 and 9). A roll 25, supported from gear housing 22 in a manner hereinafter described, extends inwardly over cloth pan or top plate 2| in spaced relation thereto. A hot shoe 26 is supported in back of roll 25 for movement to and from the latter, by means which will be described herein later. v

The support or stand 20 is intended to be provided with a box-like cover2'l, comprising a stationary rearward section 23 and a forward mov able section 2! hinged at 32 to section 22. When section 29 is in its open position shown in Figure 1, it provides an open front open top tray readily accessible from in front of the machine for reception of ironed articles. suitably mounted on cover section 22 for movement into a substantially; vertical position, permitting opening of cover section 20, as shown. and movement into a horizontal position resting upon cover 21, when section 29 thereof is closed, providing a. continuous top surface for the cover structure available for use as a table top. -When the forward cover section 29 is closed it provides in cooperation with section 28 a box-like housing enclosing the roll 25 and 'shoe 28 and associated parts above plate 2|. related features constitute the The cover 21 and subject matter of my copendingapplication for Ironing machine,-

' connected by a wall 31 at the front and the back thereof, respectively, to the front and the back walls of gear housing 23. The walls 35-35'36, 31 and 32 deflne a passage 38 having a restricted upper portion opening into neck 34 and a downwardly flaring portion opening below top plate 2|, a short distance above the bottom of gear housing 23. Wall 35 is provided at its upper portion with a semicircular recess 39 (Figure 4) of less diameter than and concentric with neck 34. A horizontal flange 33 extends along flange 36 and the front and back walls of gear housing 23, and seats on top plate 2| about the opening therein through which the lower portion of the gear housing extends.

An electric motor 40 of suitable type is bolted to the inner side of gear housing 23 in concentric relation to neck 34, with the outer end of its casing 4| seating tightly against the inner end of neck 34 and the inner face of wall 35. Motor casing 4| is of sufficient mechanical strength to serve as a load supporting member for the-roll, and has the outer surface of its outer end portion 4| accurately formed so as to be concentric with neck 34, into which it freely opens as shown. A

fan 42 is secured upon shaft 43 of motor 40 for drawing cooling air therethrough, as is known. this fanalso serving to discharge air through the outer end of motor casing 4| and thence into and through the passage 38. Motor shaft 43 is coaxial with a stub shaft 44, which is the main drive shaft of the machine, rotatably mounted in a bushing 45 through wall 32 of gear housing 23, with stop collars 46 secured thereon and contacting the inner and outer faces of wall 32 forming a substantially air tight seal about shaft 44, for a reason which will appear presently. The stub shaft 44 is connected to motor shaft 43, so as to be driven thereby, by a flexible connector 41 of any suitable known type, which accommodates any slight misalignment of the shafts. It will be understood, from what has been said that the motor casing 4| is open at its inner end, as is known and as shown in Figure 10, for free flow of cooling air therethrough. a

An inwardly flaring sleeve 48, formed of any metal or alloy of requisite mechanical strength and weight, is bolted at its outer end, by means of an inner circumferential flange 49, to the inner relation to a second race 6| end of motor casing 4| about the opening thereof.

A bearing retaining ring 50 is secured to the inner end of sleeve 48, adjacent the inner end of perforated metal cylinder 5| of roll 25, which comprises cylinder 5|, a coarsely woven fabric pad 52 wound thereon, and a relatively flnely woven fabric pad cover 53 wound over pad 52, the structure of the roll as a whole being such as to-permit ready flow of air therethrough radially thereof. The sleeve and the flange 49 and the ring 50 may be fabricated, as shown, or may be formed as a single piece, as desired. The retaining ring 'diaily outward thereof at the 53 receives a ball bearing structure 54 of known type, fitting snugly, but not too tightly, between the radially inward arm of ring 33 and roll cyl- Ring 53 is provided at its inner end with a circumferential flange 31 extending rainner side of ball bearing structure 54 and of a width to overlap the outer race of the latter. A ring 53 of leather or other suitable material, impregnated with a lubricant to avoid objectionable friction, is disposed between flange 51 and the. ball bearing structure .54, the arrangement being such as to provide a substantially air tight closure between the inner end of sleeve 43 and the roll cylinder II. It will be noted that the radially inner arm of ring ll extends'a short distance beyond the ball bearing structure 54, toward the adjacent end of roll cylinder 5|, serving as a stop for flange I1 and preventing the sealing ring 53 from being forced into binding contact with the ball bearing structure. The ring 53 is not essential and may be omitted where the parts are fitted sufllciently accurately to prevent objectionable leakage of air therethrough. Preferably,;though not necessarily, a screen 59 may be provided in the inner end of roll cylinder 5|, having a friction flt therein.

A bearing race 50 is spot welded or otherwise suitably secured in roll cylinder II, a short distance from the outer end thereof, in cooperatmg the motor casing 4|. The races 63 and 6| receive between them bearing balls 62 conveniently mounted in a suitable cage 83. An internal ring gear 64 is welded or otherwise suitably secured in roll cylinder 5|, and has an outwardly extending portion free of gear teeth. Two sectional metal rings 65, clamping between them a sealing ring 63 of felt, leather or other, suitable material, are secured in a suitable manner, as by means of screws, to the outer end of ring gear 64. The ring 66 flts snugly about motor casing 4| so as to provide a substantially air tight seal thereabout. The sealing ring 66 may be impregnated with a suitable lubricant, if found desirable, to avoid objectionable friction, and, within the broader aspects of my invention, any other suitable means may be provided for effecting a substantially air tight closure between the outer end of the roll cylinder and the'motor casing. It willbe seen that the motor 40 and the sleeve 43 support the roll, the sleeve providing a funnel for supplying air in adequate amount to the motor, and that the space 61 between sleeve 48 and roll cylinder 5| has a decided taper inwardly lengthwise of the latter and is closed substantially air tight at each end. The ball bearing structures at each end of the roll serve both as radial and thrust bearings and support the roll for rotation about the common axis of motor 40 and sleeve 43.

Motor casing 4| is provided, at the lower portion of its outer end. with an arcuate recess ex tending radially inward thereof and defining a pocket 69 partly closed at its lower side by an arched plate 10, seating at its ends in recesses in casing 4| and secured thereto by screws, the outer face of the plate 10 merging into and forming a continuation of the outer'circumferential surface of end portion 4| of casing 4|, in the area of the sealing ring 53. Plate II is of materially less width than the length of pocket 66, which receives in its inner portion a spur pinion meshing with ring gear 64. Pinion 1| is secured on the inner end of a roll drive shaft 12 [suitably secured on rotatably mounted in bosses ll and ll of walls "and ll, respectively, and driven from the motor II in proper direction for rotating roll ll in a clockwise direction as viewed in Figure 2.

A worm "ll is secured on the outer end of stub shaft ll and meshes with a worm wheel ll secured on a horizontal shaft I1 rotatably mounted jecting outward from wall 32, each provided at its outer end with a removable cap plate ll. Sleeve ll is'prcvided with a disc l! at its outer end and, intermediate its ends, with an eccentric ll fltting between bosses ll and in cooperation therewith restraining sleeve ll against endwise movement. A- bevel gearll, loose on shaft ll, at the opposite side of worm wheel I8 from sleeve ll, has secured thereto a clutch member l! which cooperates with a clutch member ll feathered on shaft 11 between boss ll andbevel gear ll. A shift lever l1, pivoted at ll on a lug ll projecting from the front wall of gear-housing ll, has operating connection at its upper end, in a known manner, to clutch member ll. Lever ll has pin and slot connection 90, at its lower end, to the rearward end of a rod 92 of the front wall of gear housing ll, there being a knob 94 secured on the outer end of rod 9|. It will be seen that when motor ll is in operation the shaft 11 is driven continuously and bevel gear may be clutched to and declutched from shaft I1 so;as to be driven thereby or not, as desired. Bevel gear ll meshes with a bevel gear 95 secured on the upper end of a vertical stub shaft 96 (Figure 3) rotatably mounted through a bearing boss 91 projecting outwardly from wall 32 of gear housing 23. A bevel pinion 98, secured on the lower end of shaft 96, meshes with a bevel pinion 99 secured on the outer end of the roll drive shaft 12. It will be apparent that the drive of the-roll is controlled by the roll clutch means, comprising the clutch members I! and 86 and the shift means for the latter member. Any other suitable means may be provided for clutching and declutching bevel gear ll to and from shaft 11, within the broader aspects of my invention.

It will be noted from'Figures 3 and that the opening through the outer end of motor casing ll is somewhat constricted, and that casing II is provided in that constricted area with a plurality of circumferentially spaced slots Ill Opening at their radially outer ends into space 61, these slots flaring inward to produce a venturi effect. When the motor ll is in operation, the fan 2 draws air through the motor and discharges this air under considerable velocity through the outer end of casing ll. The air flowing over the inner ends of openings or slots iill induces air therethrough from space 81, producing a partial vacuum in the latter effective for inducing air through the roll pad 5! and cover 53. The inward taper of space l1 lengthwise of the roll assures that air will be drawn through the roll substantially uniformly throughout the length thereof. generated during .the ironing operation, by the action of the hot shoe on the dampened articles being ironed, is withdrawn from the roll pad and discharged with the air beneath the top plate II. This continuous withdrawal and discharge of the steam, before it has been absorbed by the pad to an appreciable extent, assures that the roll is top plate 2i.

means a substantially dry condition, which avoids objectionable. drag or resistance to rotation of the roll when ironing due to excessive dampness of the roll' pad. which is conducive to more rapid ironing with the expenditure of less power for driving-the roll.

Referring to Figures 1, 2, 3, 6 and 7, eccentric ll of sleeve ll receives thereabout an eccentric strap ill secured to the, upper end of an arm ill operating in slottedguide lugs ill projecting outward from wall 82 of gearhousing ll. The lower end of arm ill is attached by a universal connection Ill to the forward end of a shoe shaft operating arm Ill, which is fixed at its rearward end on the outer end of a shoe operating shaft Ill rockably mountediin a sleeve ill disposed in back .of .and parallel with roll 2! and adjacent Sleeve "I is secured at its outer portion in a relatively short sleeve ill integral ll slidable through a boss In that manner steam with gear housing 28, and has its inner end secured in a tubular bracket Ill bolted or otherwise suitably secured to top plate II. By rotating sleeve II, and with it eccentric ll, the shoe operating shaft ill is rocked in alternately cpposite directions and to proper extent for moving the shoe ll to and from the roll 2|.

""1 provide half revolution clutch means for clutching and declutching sleeve II to shaft 11 at appropriate times. Any suitable clutch means may be provided within the broader aspects of my invention, though I preferably employ clutch means similar to that discl osed in Patent No. 1,867,839, issued July 19, 1932, to Rudolph W. Janda, ,for ironing machine, a brief description of. which will suflice here, Disc l! is provided with an outwardly projecting flange ill (Figure 6) concentric with shaft 11, the outer face of disc I! being flat or planar outwardly beyond flange lll. Disc It is further provided, in its outer face and adjacent flange ill, with a channel ill of appreciable depth, which receives a tension coil spring Ill. One end of spring Iii is anchored by a pin I I! to disc 82. At its other end spring H! has an eye Ill (Figure 'l) which hooks over a tongue ill struck inward from a clutch operating ring ill fltting about flange ill and seating upon the outer face of disc l2, providing a closure for the outer side of channel ill. An annular clutch yoke ill, of laminated construction, is disposed about flange ill andseats upon ring Ill. This yoke is provided with diametrically disposed notches lil which receive angularly disposed tabs i=ll formed integrally with and projecting outwardly from ring Iii, these tabs being outwardly offset radially of the body portion of the ring.

A star wheel ill, also of laminated construction, is disposed within the pocket or recess defined by flange ill and fits snugly about the adjacent squared end portion I20 of shaft 11.

A cdver disc iii fits about squared portion Ill of,

Flange ill has a slot llltherethrough which receives a clutch disc Ill of a size and shape to flt into notches ill of star wheel ill. Clutch 7 I yoke II is provided, in its inner edge. with a recess I 21 of proper depth to receive the portion of disc I25 which projects outwardly beyond flange I09, when this discis-in its outer or inoperative position clear of star wheel III, shown in Figure 8. The spring III urges ring H in clockwise direction.

Atrip member I20, disposed in back of shaft 11, is pivoted between its ends, at I20, in 9. lug I30 projecting outward from wall 32 of gear housing 23. Member I2! is provided with a trip finger ill, at its upper end, projecting outwardly therefrom. A compressionspring I32, confined between finger I3I and wall 22, with its ends seating about centering studs carried by wall 22 and finger I3I, in a known manner, urges trip member I in clockwise direction, as viewed in Figure 3, about its pivot I29 and normally holds finger I3I in the path of travel of the trip tabs IIO of the clutch operating ring II5. The lower portion of trip member I28 operates in slotted guide lugs I33 projecting forward from wall 32, and this member is provided at its lower end with a foot element I34.- A control rod I35, slidable through wall 32 and flange 36 normally is held 2 in its inner or retractedposition by a compression spring I36 disposed thereabout and confined between wall 32 and a stop collar I31 secured upon rod I35 and abutting flange 36. Rod I35 is disposed for contact at its outer end with foot ele--- ment I34 and has pin and slot connection I38 at its inner end (Figure 9) to a trip lever I pivoted at its rearward end, at I40, to a bracket I4I secured to the central reinforcing angle member 24. Lever I39 extends forward to within a short distance of the front of top plate 2| and is provided at its forward end with a downwardly extending arm I42 having a covering or pad of rubber or the like. The arm I42 is disposed adjaof the machine (Figure cent the right hand end 1), in-position to be readily actuated by the right knee of an operator seated in front of the machine.

With the parts in their positions shown in Figures 2 and 8, the eccentric 83 is in its lower position and the arm I02 has been moved downward, depressing the forward end of arm I05 and turning shaft I06 in counterclockwise direction, thereby moving the shoe 26 into its forward position shown, into operating relation with the roll 25. One of thetabs H8. is then in contact with trip finger I3I, spring I II is under tension, the recess I21 of clutch yoke ring I I6 is in alignment with slot I 24 of flange I09, and clutch disc I25 is disposed above shaft 11 and clear of star wheel H9, with its outer portion within recess I21. A spring pressed plunger I43 is mounted in flange I09, at the left side of slot I 24 thereof, asviewed in Figure 8, and contacts clutch disc I25 below the center thereof, yieldingly urging it outward and retaining it in its outer or inoperative positon. The clutch yoke ring H6 is provided with an extension I21 of recess I21, of less depth than the latter, for a purpose which will appear presently. It will also be noted that with the parts in their positions shown in Figure 8, the tabs II8 of clutch operating ring II5 are in contact with the following edges of notches II1.

In orderto move the shoe away from the roll, trip lever I39 is swung to the right, thereby swinging trip member I28 in counterclockwise direction- (Figure 3) and withdrawing trip finger I3I from beneath the trip tab H8 in contact therewith. The lever I39 is actuated but momentarily and is then released. When finger I3I is I21 is brought into contact with clutch turns yoke ring been turned through one moved clear of tab III, clutch operating ring III is turned in clockwise direction (Figure 8) by spring III, moving the tabs I I8 out of contact with the following edges of notches H1 and into contact with the leading edges thereof. Spring III then urgesclutch yoke I I6 in clockwise rection, so that the wall of extension I21 of recess and urges it inward. When one-of the notches I26 of star wheel II9 comes into alignment with slot I24-assuming that shaft 11, and with it star wheel H9, is be'ing rotatedspring III quickly H6 in clockwise direction forcing disc I25 in-wardinto operative or clutching position, this movement of disc I25 forcing the plunger- I43 into its inner or retracted position. Thereafter, the clutch yoke ring III holds disc I25 in itsinnr or clutching position, clutching the sleeve 19 tostar'wheel I I0, until sleeve 10 has -half of a revolution. The other tab II 8 then contacts trip finger III, stopping rotation of clutch operating rin III. The yoke clutch ring I It continues to revolve with disc 02, tensioning spring III and bringing the following edges of notches II1 into contact with tabs H8, thus stopping rotation of clutch yoke I It. When that'occurs, disc 82 continues to revolve, further tensioning spring III, until slot I24 is brought into alignment with recess I21, at which time clutch disc I25 is forced into its outer or inoperative position, by the, star wheel, and plunger I43 is projected and holds disc I25 in its outer position, The parts are then in their positions of Figure 8, except that the opposite tab H8 is in contact with trip finger I3I, the eccentric a3 is in its upper position and clutch disc I2! is belowshaft 11. The turning of eccentric 03 from its lowerposition to its upper position raises the forward end of arm I05, rocking sh-oe operating shaft I06 in clockwise direction, (Figure 2) effective for moving the shoe 26 away from the roll 25. It will be apparent that by operating the trip lever I39 the shoe may be moved to and from the roll as desired. The-plunger I43 assures that the clutch disc I25, when in position above shaft 11, will be held in its outer position, projecting into recess I21, guardin against objectionable clicking or chattering, due to disc I25 being struck by star wheel H9, or possible jamming of parts, such as might occur if the clutch disc I25 were not held in its outer position.

The shoe 26 is supported by an arm I41 loose on shaft I06 and straddling an arm I40 fixed on shaft I06. Suitable means is provided for coupling arm I41 to arm I48 for movement therewith, for moving the shoe to and from the roll in the operation of shaft I06, described above, and for quickly releasing arm I41 from arm I40 to permit of movement of the shoe rearward away from the roll independently of shaft I06. The coupling means is similar to that disclosed in the above J anda patent, and a brief description thereof will suffice. Arm I49 is slotted at its upper end for reception of the reduced neck of a coupling head I49 secured on the forward end of a rod I50 feathered in a thimble I5I screwin through a cruciform member I52 pivoted in shoe supporting arm I41, for rocking movement about a horizontal axis parallel with shaft I06. A compression spring I53, disposed about the rearward portion of rod I50, is confined between an adjusting knob I54, secured on the rearward end of rod I50, and a cup washer I55 abutting the rearward end of thimble I5I and free from rod I50. Member I52 has a downwardly extending slotted arm I56 disc I Jacent angle bar 24.

in which is pivoted a bell crank latch member I 61 disposed above a pin I66 secured in arm I41. When the arms-I41 and I46 are coupled together, the parts are in theirpositions shown in Figure 2, and the shoe siipprting arm I41 moves with shaft I46 for moving sh-oe 26 to and from roll 26. The shoe is under spring pressure, determined by the adjustment of thimble III, when it is to the roll. By turning member I62 In clockwise direction (Figure 2) a proper distance, head I49 is disengaged from arm I46 and brought into contact with a slotted web I6Il of arm I41, thereby uncoupling this arm from arm I46 and swinging it rearward about shaft I96 into a position limited by a stop I6I carried by bracket I99, whereby shoe 26 is moved rearward a greater distance than normal from roll 26. The coupling means sofar described is similar to that of the above Janda patent and need not be described here in greater detail.

In order that the shoe supporting arm I41 may be coupled and uncoupled to and from arm I49 from in front of the machine, the member I62 is provided with an upwardly and rearwardly extending arm I62, in which is secured a shouldered screw I" having areduced shank I64 operating in slot I66 of an angularly shaped arm I66, fixed at its lower end on a stub shaft I61 rockably mounted in a bracket I66 secured, as by bolting, to top plate 2I. The arm I96 and associated parts are so related that when this arm is swung in clockwise direction (Figure 2), the shank I64 of screw I69 is first subjected to a camming action effective for turning member I62 in clockwise direction, as. above described, and thereafter the "shoe supporting arm I4! is swung rearward away from roll 25. In this operation the bell crank I9I moves by gravity, as the shoe supporting arm I41 moves rearward, into position with end surface I69 of arm I16 thereof above and in front of pin I64, arm I1I of bell crank I61 then extending forward toward web I12 of arm I46; as in the above Janda patent. When arm I41 is swung in counterclockwise or forward direction (Figure 2) after the releasing operation described, the end surface I69 of arm I10 of bell crank I91 contacts pin I66 and shoe supporting arm I41 thereafter moves forward with arm I66. when coupling head I49 is properly positioned above and adjacent the upper end of arm I46, arm "I of bell crank I51 contacts web I12 of arm I46, turning bell crank I51 in counterclockwise direction. and releasing it from pin I66, after which member I62 turns in counterclockwise direction, in the continued movement of arm 10 lever I82 is connected by a link III to the rearward end of release lever I66 pivoted at I61 on a bracket I66 secured to the'front angle iron 24, adjacent the left end of the machine. Lever III has at its forward end a downwardly extending arm I69 provided with a resilient covering or pad of rubber or other suitable material. The arm I42 of trip lever I99 and the arm I69 of release lever I96 are disposed so as to be readily actuated by the right knee and the left knee, respectively, of an operator seated at the front of the machine. when the lever I66 is swung counterclockwise (Figure 9), the arm I66 (Figure 2) is swung clockwise, uncoupling arm I41 from arm I46-and swinging arm I41 rearward, in the manner above described. when shoe 29 has been moved rearward a short distance, in this uncoupling operation, it and arm I41 continue to move rearward by gravity until arm I41 contacts stop I6I. During this rearward movement of shoe 26 and arm I41, the spring I" is placed under increasing compression and serves as a cushion to retard rearward movement of arm I41,

preventing it from striking stop I6I an objection- I66, so as to move the neck of head I49 into the slotted upper end of arm I46, completing the coupling operation, as in the above identified J anda patent.

A second arm I19 is secured onstub shaft I61, at the opposite end thereof from arm I66, and extends downward through a slot I14 in top plate 2i. The lower portion of arm I13 is of increased width and is provided with a lengthwise slot I15 which receives a pin I16 secured in an arm I11 rigid with a collar I19 fixed on a rod I19 slidable through two of the reinforcing angle bars 24 (Figure 9) Rod I19 extends transversely of plate 2i and is urged rearward by a compression spring I69 disposed thereabout and confined between collar I16 and the central angle bar 24. At its forward end rod I11 has pin and slot connection IN to one arm of a bell crank lever I82 pivoted at I43 on a bracket I64 secured to the ad- The other arm of bell crank ably hard blow such as to subject the machine to objectionable shocks or cause possible breakage of parts. The release lever I69 and associated elements thus provide for quick release of the roll from the shoe in the event the operator's fingers get caught between the roll and the shoe, or in the event such quick release becomes necessary for any other reason. In order to effect the recoupling operation, the operator grasps arm I69 of lever I86 with her hand and swings lever I96 in clockwise direction (Figure 9), swinging arm I66 counterclockwise (Figure 2), coupling arm I41 to arm I46 in the manner above described.

Referring to Figure 2, the gear housing 23 is provided with an interior switch box I99, preferably formed integrally therewith, at its lower forward portion. Switch box I9Il opens through the front wall of gear housing 23 and receives a multiple switch block I9I, of known typ conveniently carried by a mounting plate I92 secured in a suitable manner, as by screws, to the front wall of gear housing 23. The switch block I9I carries two switches, one for the motor and the other for the heating elements within shoe 26, each having an operating handle I94 extend at oneend, is led through the bottom wall of gear housing 23 into the switch box I96 thereof, and is appropriately connected to the switch block I9I. A flexibly armored cable I91, connected to one of the switches of block I9I, is led through the bottom wall of gear housing 29 and thence through top plate 2i to shoe 26, to the heating elements of which the wires of cable I91 are appropriately connected. A second flexibly armored cable I98, provided with a quickly detach-. able connector I99 of known type, is connected to the other switch of block I9I, from which it is led through the bottom wall of gear housing 23, thence upwardly through passage 39 (Figure 3) into motor casing 4I, through the latter outwardly of fan 42, along motor casing H to sleeve 48, and then through the wall of sleeve 46 and into the inner end of motor'4I'I, to which the wires of cable I99 are appropriately connected in 11 ments of shoe 22, under control of the respective switches of the switch block "I.

The gear housing 22 is provided. at its outer side, with an outer wall 200 extending upward a short distance above top plate 2|, and the forward edge portion of gear housing 22 is thickened at 20l. A lower cover plate 202 is secured over the outer side of gear housing 22, conveniently by screws, extending upward from wall 200. An upper and thinner cover plate 202. formed at its lower edge to provide a shoulder 222' seating on the upper edge of plate 202 and a depending lip 222" seating against the inner face of plate 202, is secured over the outer side of gear housing 22, also conveniently by screws. The plates 202 and 202 together constitute a removable cover for the outer side of gear housing 22 whereby access to the parts therein mayreadily be had. It will be understood that suitable sealing gaskets may be interposed between the gear housing and the cover therefor, though not shown.

In Figures 11, 12 and 13, the gear housing 22 is of substantially the same construction as gear housing 22 of Figures 1 and 2 and requires no detailed description. Worm 12, secured on stub shaft 44, meshes with worm wheel 224 mounted on a horizontal shaft 205 rotatably mounted in boss 202 of housing 22 and in a bearing boss 221 projecting outward from wall 22 of housing 22. A bevel pinion 202 is fixed to worm wheel 204, forming a unit therewith and this unitis confined between bearing boss 20'! and stop collar 209 fixed on shaft 22!, whereby both the latter and the unit 224-202 are restrained against endwise movement. The unit comprising worm wheel 204 and bevel pinion 222 may be loose on shaft 205 or keyed thereto as desired. Bevel pinion 202 meshes with a bevel pinion 2|I fixed on the upp r end of a vertical stub shaft 2 (Figure 13) rotatabiy mounted in a bushing 2|2 extending through a bearing bos 2 projecting outward from wall 22'. A bevel pinion 2, fixed on the lower end of stub shaft 2| I, meshes with a bevel gear 2|! rotatably mounted on the outer end portion of roll drive shaft 2|, mounted for rotation in a bushing 211 in a bearing boss 2l0 projecting outward from wall 22'.

The gear 2|5 constitutes an element of means for driving the roll shaft 2| at either of two speeds and for actuating the shoe operating shaft 106, from the motor driven stub shaft 44. Such means is similar to that disclosed in Patent No. 2,054,631, issued September 15, 1936, to Rudolph W. Janda, for Ironing machine, and a brief description thereof will sufiice. Gear 2|! is provided, at the outer portion of its hub 2", 'with a spur pinion 2|2, conveniently formed integral therewith. A ring member 2|2, mounted for relative rotation on hub 2", is provided with a first series of inner teeth providing an internal ring ear 220, a second series of inner teeth providing an internal clutch element HI, and, adjacent its inner end, with a series of teeth providing an external ratchet element 222. A disc 222 is fixed on the hollow outer end of shaft 2 l2, at the outer end of hub 2", and shaft 2|2 slidably receives a hollow plunger 224 urged outward by a compression spring 222, confined between a disc 222 seating in shaft 212 and the plunger. Plunger 224 is provided with an outwardly tapering frusto-conical element 221 and a reduced tip element 222 projecting outward therefrom. The body portion of plunger 224 is cylindrical and, in the outer position of the plunger shown, contact the inin bosses ner ends of two clutch dogs 222 slidably mounted 220 and 22! formed integrally with hub 222 of disc 222 and with disc 222 at the periphery thereof, respectively. these bosses and the clutch dogs being aligned diametrically of disc 222.- Hub 222 and shaft 2|2 are provided with aligned bores which slid-ably receive the inner end portions of the dogs. Whenthe dogs are projected, the tooth elements element 221 of ring member 2|2, clutching disc 222 and member 2|2 together for rotation as a unit. An arcuate wire spring 224 passes loosely through dogs 222 and yieldingly urges them toward each other, while also restraining them against turning movement. When the plunger 224 in its inner position, bringing element221 thereof opposite the inner ends of dogs 222, the latter are retracted by spring 224 and thereby declutched from clutch element 22l, at which tim the ring member 2|-2 and the disc 222are free for relative turning movement.

A bracket 225 is suitably end of a thick rib or An operating lever secured on the outer boss 222 of gear h'ousing 202. 221 is rockably mounted on bracket 225, by a pivot pin 222, and extends up-,

ward therefrom into contact with tip 222 of plunger 224. Lever 221 is provided at one side thereof with a depending finger 222 held in contact, by spring 221, with a cam member 240 secured upon the rearward end of a control shaft 2 rotatabiy mounted through the front wall of housing 202 and bracket 220. A suitable handle 242 is secured upon the forward end of shaft 2" in contact with the front wall of housing 202,

which may be provided with suitable legends, such as "Fast," Stop and Slow, handle is moved to indicate the proper adjustments of the control means for driving the roll at high speed, stopping it and driving it at low speed.

A pawl 243 is'pivoted on bracket 225 and extends upward tli'erefrom into proximity to ratchet element 222 of ring member 2|2, At its lower end, below and readward of its pivot, pawl 242 is provided with a forwardly extending tab 244. A wire spring 245 is fixed at its lower end to bracket 22!, conveniently by means of one of the mounting screws therefor, from which it extends upward and is bent about the upper end portion of pawl 242, urging the latter toward clutch element 222. The cam member 240 is appropriately formed and has three positions corresponding, respectively, to the Fast, "Stop" and Slow positions of handle 242. When handle 242 is in its Fast" position, cam member 240 is in its position shown, in contact with tab 244 of pawl 242, holding the latter out of engagement with ratchet element 222, while permitting movement of finger 22s of lever 221 into its inward position and outward movement of the upper end of lever 231 by plunger 224, then held in its projected position by compressing spring 222. In the Fast" position of cam member 240, the disc 222 and the ring member 2|! are clutched together, and the ring member 2|9 is free to rotate and is locked to spur pinion 2|2 of gear 2|2, by a spur pinion 24S rotatably mounted on a stud 246 secured in disc 222 and meshing with pinion 2| 2 and with ring gear 220. The roll shaft 2| 6, and the roll 25, are then driven at high or "Fast speed from the motor driven stub shaft 44. By turning handle 242 into "Stop position, the cam member 240 is so disposed as to hold pawl 242 in its released position shown, while also holding finger 222 of lever 221 in its outer poover which the 222 en age the clutch 13 sition, thereby holding the upper end of lever 281'in its inner position, so that plunger224 is then held in its inner or retracted position. The disc 223 is then declutched'from the ring member 2", which is free to rotate, and the roll shaft 2 is not driven. 'When'handle 242 is turned to "Slow position, the cam member 248 is so disposed as to release the pawl 243, which is then moved into engagement with ratchet element 222 and holds ring member 2|8 against rotation in counterclockwise direction (Figure 12), and to hold finger 238 in its outer position, declutching disc 223 from ring member 2". The pinion 248 is then driven counterclockwise by pinion 211 and travels clockwise around the internal ring gear 228, carrying with it the disc 223 and driving the roll shaft 2| 8 at slow speed. The roll 28 may thus be driven at either high or low speed, or stopped, in the con- I tinned operation of the motor 48, by the drive and control meansabove described.

Bevel gear 2|8 meshes, at its lower side, with a bevel pinion 288 secured on the upper end of a vertical shaft 28| rotatably mounted through a bushing 282 in bearing boss 288 projecting outward from wall 32*. Shaft 28| is squared at its lower portion, at 284, for reception of a star wheel of an eccentric and clutch assembly 288. Below squared portion 284 the shaft III is provided with a reduced cylindrical portion 288 extending into a boss 281 projecting upward from the bottom wall of housing 283, the lower end of shaft 28| seating upon a bearing ball 88. The clutch assembly is similar to that. of the Janda Patent No. 1,867,839 and requires no further detailed description. It comprises an eccentric 288 seating upon the upper end of boss 281 and receiving an eccentric strap 288 at the forward end of an arm 28| connected at its rearward end, by a universal connection 282, to the lower end of an arm 283 fixed at its upper end on shoe operating shaft I88.

In Figures 11 and 12 the parts are shown in the positions they occupy when the shoe has been moved to the roll. The clutch'means of the assembly 288 is controlled by a trip finger 284 pivoted on a lug 288 projecting from the front wall of housing 283, this finger normally being disposed for contact with one of the tabs H8 (in the same manner as in Figure 8) for declutching the eccentric 288 from shaft 281. A rod-288 is connected to the inner end of finger 284 and extends therefrom upward 14 position without provision of of Figure 8. 'In that respect, as well as in having the eccentric contiguous to the disc receiving the tension spring, the assembly 288 of Figures 11 to 13,. inclusive, diifers from the clutch and eccentric assembly of Figures 2 and 8 to 8, inclusive, assembly 288 being similar to the eccen trio and clutch assembly of Janda Patent No.

1,867,839, as noted.

A release lever 288 is pivoted at its upper, end

on pin 238 and straddles the lower portion of lever 231, extending downward into proximity to A 'set the eccentric and clutch assembly 288. screw 21!! is adiustably secured through the upper end of lever 288, in position tocontact the outer face of lever 231 above pin 238. Lever 288 is further provided with a rearwardly offset and inwardly extending trip finger 213 .overlying pawl 243 and disposed to move the latter from its holding position to its releasing position and to hold it in its latter position, when lever 288 is swung counterclockwise about pin 238 from its inner position of Figure 11 to its outer position. A cupped cam plate 21] is secured on the upper face of assembly 288 for rotation therewith,and is provided with a cam element 212 projecting radially outward therebeyond. The cam element is disposed to contact the lower end of arm 288 as the assembly is turned into the position which it occupies when the shoe 28 has been moved rearward away from the roll. That swings lever 288 outward and, through screw 210, swings lever 231 inward so as to declutch disc 223 from ring member 2|3, while also moving pawl 243 into releasing position and holding there, or preventing, movement of pawl 243 to holding position if it is already in releasing position. In that manner rotation of the roll 28 is stopped automatically when the shoe is moved from the roll.

40 When the assembly 288 is turned through the through boss 288 into a hollow boss 281 at the top of housing 283, which receives a button 288 secured on the upper end of rod 288.

- Button 288 normally is held raised by a compression spring (not shown) confined between the button and the bottom wall of boss 281. in a known manner, so as to hold the outer end of finger 284 depressed into contact with asembly 288 in the path of travel of tabs 8 so as to be contacted thereby. When button 288 'is depressed, the outer end of finger m is raised into clutch releasing position, the eccentric 288 is clutched to the shaft 28| for rotation therewith, and upon completion of one half revolution of the eccentric one of the tabs 8 contacts finger 284 thereby declutching eccentric 288 from shaft 28L In that manner, shoe operating shaft I88 is rocked in alternately opposite directions for movingthe shoe 28 to and ,from

the roll 28, as has previously been explained. Since the assembly 285 rotates about a vertical axis, the clutch disc I28 will remain in its outer succeeding half revolution, the cam element 212 is moved clear of the lower end of lever 283 and the parts are returned to the positions they 00- cupled prior to outward movement of lever 288. Accordingly. if the roll 28 was being driven at either 'Fast" or Slow" speed, when the shoe 28 was moved away from roll 28, the drive of the latter at the selected speed will be reestablished automatically upon return of the shoe to the roll. Likewise, if the roll 28 was not being driven when shoe 28 was moved rearward, it will not be driven upon return movement of the shoe. That is advantageous, in that by setting the handle 242 at Stop position, the shoe 28 may be moved to and from the roll 28, while the latter remains stationary, when'it is desired to use the machine for pressing suits and like articles, instead of for ironing, k

As above indicated, and as will be understood by those skilled in the ironing machine art, changes in construction and arrangement of the parts of the ironing machines ofmy invention may be resorted to without departing from the field and scope thereof, and I intend to include all such variations, as fall within the scope of the appended claims, in this application in ,which the preferred forms only of my invention are disclosed. 1
