My ironer I comprises a gear casing 2 Ahaving a dependingtubular boss 3. On one end of casing 2 is provided a laterally extending tubular boss 4 in which is positioned a laterally extending tubular member I'.

In member'i and rotatab;y mounted therein is a tubular shaft I.' On the outer end of shaft 6 is secured an ironer shoewsupport. Such support may be of different away, 0n

designs but for the-purpose of explaining my invention I have here shown a. new and improvedironer shoe support which has been disclosed and claimed by me in my co-pending application for, Ironer filed Octoberv 9, 1929, Serial No. 398,386, which issued into Patent No. 1,865,048, dated June 28, 1932.

On the outer end of shaft 6 is rotatably mounted a yoke lI, (Figure 11) y On-the upper end of yoke I is pivotally mounted a shoe support 8 as by a pivot pin 9 to the forward end of which and above the pivot 9 is secured the shoe I Il.

Shoe I0 is curved in cross section with its inner face conforming to the contour of the ironer roll I I hereinafter to be described.

Within the shoe I0 a resistance heating unit I2 is connected as by a cable (Figure 1) I 3 to a source of potential not shown.

A spring I4 has its upper end secured to the rear face of shoe. I0 and has its lower end bearing against the inner face of yoke 'I to hold shoe I0 inthe raised position when the same is out of Contact ywith roll II.

Between the sides of yoke "I, and secured to shaft 6 as by a pin" I 5, I provide a member I6 which has its outer end provided with an aperture I'I through which extends the shaft I8.

The lower end of shaft I8 is provided with a transverse pin I9 normally abutting against ,a curvedguide 20. Theupper end of shaft I8 is provided with an adjusting nut 2 I, and spiral spring 22 has one end abutting against nut 2|, and has its lower end abutting against member I6 to normally urge shaft I8 to the raised position with pin I9 abutting against guide 20.

On the lower end of'yoke I is pivotally mounted as by a pivot 23, a. dog 24 which carries on its upper end a', hooked portion 25 adapted to normallyV engage pin I9 to lock yoke 'I to me'mber I6.

Aspring 26 has one end secured to member I6 and has the other end secured to dog 24 to releasably hold hook 25 in registration with pin I9.

. With the parts in the normal position just described any movement transmitted to member I6 through shaft IiY will be transmitted to yoke TI.

On the upper'end of yoke 1 is pivotally mounted on the pivot pin 9, a bell crank 2'I.

' In the upper arm 28 of bell crank 21, I provide a vertically extending shaft 29 carrying a knob 30 on its upper end. The other arm 3| of bell crank 21 is in engagement with the upper end of a shaft 32 slidably mounted in the upper end of yoke 1 and having its lower end pivotally mounted in the outer end of dog 24.

The lower end of ybell crank 21 has a stop 33 which abuts against' the yoke 1 to limit the movement of bell crank 21 in one direction. With the parts in the positionjust described. member I5, yoke 1 and shoe AIll will be actuated as a unit through movement of shaft 5, which movement will b hereinafter described, but which is adapted to move shoe I5 towards and from roll II.

When itis desiredto release yoke .1 from member I5 so that yoke 1 carrying shoe I5 may be moved about shaft 5 to carry shoe I5 out of engagement with roll I I, the bell crank 21 is moved I about its pivot by means of shaft and this. movement will cause theend 3| of bell crank 21 to move downwardly carrying before it shaft 32. 'I he downward movement of shaft 32 will cause dog 24 to be moved about its pivot 23 to carry hook 25 out of engagement with pin I9 to break the connection between yoke 1 and member I5.

After this initial movement has been completed, shaft 29 may be moved still further in the same direction causing yoke 1 to pivot about shaft 5 to V-move shoe I5 out of engagement with the als roll Il. The position of parts lafter this movement of shaft 29 has been completed is indicated-in dotted lines on Figure ll.

Forthe purpose of limiting the movement of yoke 1 just described, I provide on yoke 1 (Figure 12) a pin 34 whichs adapted to contact with a finger 35 carried on tubular member 5. Withthe parts in the .las t described position indicated in dotted lines it will be notedthat the hook 25 is beneath but in the path of movement of the pin. I9. When the latter is thereaftermoved downwardly through the rotary movement of member I5 `on shaft 5, which movement of `member I5 subsequently takes place through the operation of the mechanism about to be described, pin I9 will ride downwardly past hook 21 due to-the fact that it will force dog 24 about its pivot against the action of spring 25. i

After pin I9 has' moved downwardly beneath hook 25,'spring 25 will cause dog 24to move about its pivot to bring hook 25,into registration with pin I9` so that the parts will again become vlocked in the initially described operative'position, and any further movement of member I5 will cause yoke 1 and shoe I5 to be moved with it as a unit;

A secondary laterally extending tubular boss 35 is provided on casing 2. A tubular supporting shaft 31 hasl one end secured in boss 35 and extending outwardly therefrom.

' The ironing roll II (Figure 4) has secured in its inner end as by screws 35 an annular lals internal gear 39 provided with a central hub 45 rotatably mounted on shaft 31;

Adjacent theouter end of roll I I is provided an internally positioned plate 4I carrying a centrally located bearing 42 in which shaft 31 is positioned.

In the outer endl of shaft 31 is secured a plate 43 having a centrally located threaded aperture 44.

`A disk 45 of greater-diameter than the diameter ofbearing 42 is secured on the end of shaft 31 a; by a screw 45 whichv is in threaded engagement with plate 43 to hold' roll IIV in positin on shaft 31.

On the inner face of' casing 2 is rovided an inwardly extending tubular bossl 41 and on face plate 45 ofl casing 2 and coaxial with boss 41 is provided an outwardly extending tubularf A shaft 55 has one end rotatably and slidably mounted in a bearing member 5I carried in boss .49 and has its other end rotatably andf slidably mounted'in boss 41.

Shaft 55 is less in length .than the distance between the outer ends of the apertures in bosses 41 and 49 to permit a limited axial movement of shaft 55 in relation tc such bosses 41 and 49.. (Figure 4.)

A clutch member `52 is secured on shaft 55 as by a k'ey 53. The key-way 54 in member 52 is suillciently long to permit longitudinal movement therein of key 53. Key 53 is rigidly secured in shaft 55.

.A spiralgear I55 is rotatably mounted on shaft v55 and carries on one face a laterally extending hub 55 to which is secured a'clutch member 51, as by screws 55, adapted to coact with 4member 52 in a mannerhereinafter to be described.

The opposite face of gear 55 is provided with a plurality of circumferentially spaced and preferably tapered jaws 59.

A spurgear 55 carryingv a bearing ,member 5I is rotatably mounted on shaft 55. face of gear is provided a plurality ofxcircumferentially spa'ced Aand preferably tapered jaws 52 adapted to coact with jaws 59 on` spiral.

Intermediate gears sitioned a disk 54 which bears against the face of Sear 55. L f

On'the face of gear-55 opposite to that on which the jaws 52 are carried is secured an annular member 55 in spaced relation' to that face ofgear 55.

A spiral spring 55 encircles boss 41'and has one end abutting 'against casing 2 land the other end abutting against member 55 to normally urge gear 55 towards gear 55 and jaws 52 into engagement with jaws 59.

The end of shaft 55 which is positiied in boss 41 is provided with a recess 51 in which'is positioned a spiral spring 55.

Spring 55 has one end abutting against casing 2 and has the other end abutting against the bottom of aperture 51 to normally urge shaft 55 towards boss 49. On the side of casing 2 is positioned a laterally 'extending boss 591m which is journaled a shaft 15. The inner end of shaft 15 (Igure 8) has secured thereto-as by a pin 1I, a spur gear 12 in mesh with gear 55.

0n the outer end of shaft 15 and secured the'relhas secured to the upper end thereof, as by a pin 15, a pinion gear 1'9 in' mesh with gear 55. The hub of gear 19 is greater in diameter than the diameter of bearing member 1 5. Shaft 11 is provided witha shoulder 11 adjacent the lower end of bearing member 15. Withv this arrangement of parts shaft 11 is held against axial displacement in relation to bearing member 15.l

.On the lower end of stub lshaft 11is provided a transverse pin 55 (Figure 2) vfora purpose hereinafter to be described.

The clutch members 52-and 51 coact inthe following way., A curved plate 5 I is pivotally mounted at approximately its center point on to clutch member 52 by means of a pivot pin 82.

One end of plate 8| has secured thereto an end of a spiral spring 83, the other end of spiral spring 83 being secured to plate 52 as by a pin 84.

'Spring 83 normally urges the end of plate 8| to which it is attached towards clutch member 51. In parallel relation to plate 8| is pivotally mounted on pivot 82 a dog 85 having a lug 86 adapted to register with .one of the slots 81 carried on the periphery of clutch member 51.

The end of plate 8| to which spring 83 is attached is offset, as indicated at -aon Figure 6, to bring it in opposed relation with the end of dog 85, a spiral spring,88 being interposed between plate 8| and dog 85.

Plate 8| has a laterally extending lug, indicated at '-b on Figure 6, adapted to contact with the outer face of dog 85 so that when plate 8| is urged by spring 83 towards clutch member 51 dog 85 will be carried with it to bring lug 86 into registration with one of the slots 81.

For the purpose of holding dog 85 out of engagement with clutch member 51 I provide in casing 2 a rock shaft 89 having on its outer end a finger lever 90 pinned thereto as by a pin 9|.

On the inner end of rock shaft 89 is provided a depending rock arm 92 with an inwardly curved end 93 adapted to begmoved into and out of the path of movement of plate 8|.

A coil spring 94 encircles rock shaft 89 a :1d has one end abutting against casing 2 and the other end encircling rock arm 92 to normally hold rock arm 92 in the path of movement of plate 8| The parts are soarranged that rock arm 92 is adapted to contact with either of the ends of plate 8| depending upon the position of clutch member 52 when the rock arm 92 is moved into the path of movement of plate 8|.

When the rock arm 92 is in the path of movement of that end of plate 8| which is secured to spring 83 and plate 8| comes into contact with rock arm 92, plate 8| Will be held against further movement Which will cause the same to be 45lmoved about the pivot 82 compressing spring 88 and this, in turn, will cause dog 85 to be moved about pivot 82 to carry lug 86 out of engagement with the slot 81 with which it was in registration.

Spring 88 will then expand to further move dog 85 about its pivot 82 to carry lug 86 to a po- .sition in spacedrelation to clutch member 51 so that there will be no possibility of any contact between dog 85 and clutch member 51 during the operation of the mechanism.

If rock arm 92 is in the path of movement of the opposite end of plate 8| and plate 8| comes into contact with rock arm 92 a similar movement will be conveyed to dog 85.

For the purpose of yproviding a manually operated means whereby clutch member' 62 may be held dis-engaged from clutch member 59 independently of the operation of theother parts of 'the apparatus I provide (Figure 8) a depending shifter arm 94 preferably of spring metal having its upper end secured in casing 2 as by a screw 95 and-having its middle portion in registration with the periphery of member 65 and disposed between such member 65 and gear 60.

The lower end of member 94 (Figures 9 and l0) is provided with a slot 96 in which is positioned a pin 914 secured incasing 2. Adjacent pin 91 and in casing 2, I provide a rock shaft 98 having Aa. nger lever 99 secured to the outer end thereof as by a pin |00. 75 0n the inner endof rock shaft 98 is secured, as

by a set screw 0| a cam member |02 adapted,

when shaft 98 is rocked, to contact with the end of shifting member 94 to move the same laterally to cause gear 60 to be moved axially and out ofv with the shifting member 94, the different parts of the apparatus will be permitted to function in a normal way but when the high side of cam I0?. is brought into registration with shifting member 94 the gear 60 will be held out of engagement with the gear 55 and will remain in that position until the lever 99 is again manipulated. It will be noted that the cam |02 may be operatedto disengage clutch member 62 from clutch member 59, or may be operated when clutch member 62 is not in engagement with clutch member 59, thereby enabling the roll to be stopped while the shoe is in engagement with the roll, or when the shoe is away from the roll, enabling the roll to be retained disengaged from its driving mechanism y upon subsequent movement ofthe shoe in engagement with the roll.

For the purpose of providing a means for operating the shaft 6, I provide on the inner end of shaft 6 and secured thereto, as by a pin |03, rock arm |04, a plug |05 being preferably positioned in the end'of tubular shaft 6 for the purpose of stiiening the same.

Rockarm |04 hason its outer end opposed jaws |08 and |01 between which is positioned a cam member |08 integral with clutch member 52 and eccentric to shaft 50.

When the cam member |08 is in the position shown in heavy lines on Figure "1, the rock arm 4|04 will be in the lowered position which will have caused shaft 6 to be moved in a counterclockwise movement to bring shoe |0 into registration with roll l When cam |08 is in the position shown in dotted lines on Figure '7, the rock arm |04 will have been moved to the raised position which will have caused shaft 6 to be moved in a clockwise direction to carry shoe |0 out of registration with roll It will be apparent that the movement of cam .l |08 and the consequent movement of rock armV |04 will only take place when dog 85 is in registral tion with clutch member 51 to cause clutch member 52 to be moved as a unit with clutch member f For` the purpose of automatically dis-engaging gear 60 from gear 55 intermittently, I provide a after the time when the shoe leaves the roll, and

will start rotating before the shoe re-engages the roll.

The bearingv member 5| (Figure 13) is provided on its inner face with a cam surface |09 with which the outer end of key 53 is in contact so that when clutch members 52 and 51 are in engagement to cause the rotation of shaft 50, key 5,3 will move along cam surface |09.

When key 53 moves to the high side of cam surface |09, the shaft 50 will be moved axially to cause collar 64 to b ear against gear 60 to move the latter axially against the action'of springs 66 and 68 and out of engagement with gear 55 so that roll will come to rest.`

When key` 53 has moved to the low side of camreverse directionthr'ough the action of springs 66 and 88 to carry gear 6|) towards gear 55 and jaws 62 into registration with Jaws 59 to cause gear -BII to be rotated with gear 55 as a unit. v

In the operationof ironing machines it is deof cam surface |09 and gear will bein clutching engagement with gear 55.

When the cam |08'is in the position wherein the crank arm |04 will be in the raised position with the shoe -III out of registration with roll I I, the key 53 will be in'registration with the high side of the cam surface |09 and the gear 60 will have been moved axially out of engagement with gear 55. f

For the purpose of illustrating the operation of my device, I have here shown a portion of a washing machine I I0 having the usual upper and lower frames III and ||2. (Figure 2.)

A supporting tube ||3 has its lower end secured in a gear casing ||4 which, in turn, is se- -cured as by bolts ||5 to the bottom frame |2.

' Supporting tube I Il extends vertically through a yoke I I6 secured as by bolts I to the top frame In supporting member ||3 `is positioned a shaft l| I8 having its lower end extending into gear casing I I4 and having secured to such lower end as by a pin IIS, a gear |20 which, in turn, is connectedl through suitable gearing to the motor, not shown, of the'washing machine.

On the upper end of shaft ||8 is secured, as by a pin I2I, a tubular clutch member |22 provided in its upper end with a transverse slot |23 adapted to receive in clutching engagement the lower end of shaft 11 carrying the transverse'pin 80.

The relation of parts is such that when my Lde 7 vice is in position on the upper end of supporting tube- I I3, the transverse pin 80 will be positioned inthe slot |23 but will not seat in the bottom of such slot so that the weight of my device will vbe supported entirely on tubular member ||3 and n end thrust will be conveyed to shaft I Il.

Adjacent the upper end of supporting member III, I'provide` a plurality of circumferentiaily spaced apertures |24. In the lo end of boss I (Figure 3) is provided a latera y extending tubular boss |25 in which is slidably mounted a plunger |25. The inner en d of plunger |25 is providedwith a head `|2`| adapted to register with an aperture |24.

Encircling shaft |25 and in boss |25 is a spiral spring-'|20Q having one end abutting against head |21 and having the other' end abutting against the outer end of boss .|25 to normally urge shaft head'l21 into an aperture |24.

For the purpose of. providing a convenient` means for retracting shaft |26 fromv an aperture |24 to permit the removal of my device, I pro-- vide on the outer end of shaft |26, a knob |20.S

The advantagesof 'the apertures |24 in--supporting tube lllconsists inthe fact that the ironer may be placedin position on supporting tube i3 in a selected one of a plurality of angupositioned on tube 'I I 4I'interchangeabiy 4lar positions in relation to the washing machine IIU.

Although I Ahave not here shown a wringer, it will be understood that the wringer be used with the washing mechanism is adapted to be with my ironer so that either the wringer orfthe ironer may be operated directly from the washing machine mechanism as desired.

It will also be understood that although I have shown and described a specic structure and form 'and relation of parts as an exemplication of an embodiment of my invention, I do not desire to restrict myself to the exact size or relation of -parts as various changes may be made within the scope of the appended claims.
