10 Claims. (Cl. 223-43) This invention relates to garment pressing machines and more particularly to machines for creasing and pressing bifurcated garments such as trousers.

In the use of conventional steam pressing machines, an average often separate lays is required in order to press a pair of trousers and the number of manipulations necessary in hand pressing is, of course, greater.

An important object of this invention is to provide a machine for pressing trousers in one lay.

Another important object is to provide a pressing machine which will eliminate the possibility of shining the trousers material.

A further important object is to provide a machine which will cause a fully defined crease to be given the trousers.

In addition, an important object is to provide a machine which will materially decrease the time necessary in pressing and creasing trousers.

Other objects and advantages will be apparent during the course of the following detailed description of the invention, taken in connection with the accompanying drawings, forming parts of this disclosure, and in which drawings,

Fig. 1 is a top plan of the new machine.

Fig. 2 is a vertical section, substantially on.

the line 2-2 of Fig. 1. Fig. 3 is an enlarged fragmentary vertical'section of a presser head and a former, forming 2 at I2. Adjacent the other end portion of the base member ID, a suitable uprightor bracket I3 is rigidly connected to the former and supports portions of the actuating means E.

Now, with reference to the trousers support and crease-defining means B, the same includes a trousers waistband support I5 which may comprise a plurality of suitably curved springy-metal parts of the new machine, with a portion of a trouser leg shown in dots and dashes.

Fig. 4 is a fragmentary vertical section, sub- I stantially on the line 4--4 of Fig. 1.

Fig. 5 is an elevation of a blower and heater i associated with the new machine.

In the drawings wherein for the purpose of illustration is shown a preferred embodiment of the invention and wherein similar reference characters designate corresponding parts throughout the several views, the new pressing machine comprises a machine support structure A; trousers support and crease defining means B; upper heads structure C; lower heads structure D; actuating means E for the means B and structures C and D; fluid-conveying means F for the means B and structures C and D; blower bands, such as the bands I5, I 1, l8 and 19, with their end portions in good frictional overlapping contact as in Fig. 2. Each band may be provided with means 20 to adjustably moveit inwardly or outwardly and retain it in any selected adjusted position. Each of such means may be a screw-threaded projection 2| welded or otherwise secured to the inner face of a selected band I 6, I1, I 8 or I9, extending into the screw-threaded bore ofa rotatable member 22, swivelled to a fixed support 23 carried by (as being welded to) a centrally-disposed conduit 24 (which. carries all four of the supports 23) supported by arms 25 rigidly carried by the outlet mouth structure of the blower means I-I-to be subsequently described. Rotation of the member 22 will cause the associated projection 2| to move axially toward or away from the conduit 24, thus permitting adjustment of any one or more of the bands l6, l1, l8 and 19 to accommodate trousers waistbands of various sizes which, may be drawn over the support l5 and detachably secured thereto as by a conventional buckle strap (not shown).

Additionally, the trousers support and creasedefining means B includes four crease definers or formers of which two definers, .each designated as 26, are upper definers, and two definers, each designated as 21, are lower definers, best shown in section in Fig. 4. Each definer 26 or 2! comprises an elongated preferably thin but rigid fin or blade 28 rigidly carried radially by a suitable conduit-support 29 (as being welded thereto) and may be strengthened by the member 30. The definers are grouped substantially as in Fig. 2 so that the outer narrow edges 31 of the two upper definers 26 will define the location of one crease in each trouser leg at the like sides of the trousers and the outer narrow edges 3i of the two lower definers 2! will define the location of one crease in each trouser leg at the opposite like sides of the trousers since the definer fins are substantial1y apart. The edges 3| are, preferably, curved and may be said to provide substantially line contact with the trousers leg.

A furtherportion of the means B, comprises means 32 to move the lower definers 21 toward and away from the upper definers 26 so that the narrow outer edges 3| of the blades or fins 29 will contact the trousers legs from the inside of the latter (when the legs are pulled over the definers 26 and 21) and stretch the legs taut as may be appreciatedin Fig. 3 where a portion of a trousers leg in transverse section is shown of the upper definers 26 over which is trained a suitable flexible member 31, as rope, cord, wire or the like, secured at one end to an eye 38 carried by the associated conduit-support 29 of the lower deflners 21. The other end of the member 31 extends to an oscillating member 39, as an arm, carried by the actuating means E to be subsequently described. As the member 39 oscillates, the two associated definers 26 and 2! will move selectively toward and away from each other.

It will be noted, in Fig. 1, that the outer end portions of each of the associated conduit-supports 29 are joined by a hollow U-section 49 of flexible material, not afiected by steam, and

the inner end of each conduit-support 29 associated with the crease definers 21 carries a hollow flexible material section 4|, preferably of the same material as the sections 40.

Since the upper heads structure C and lower heads structure D are alike in parts, similar reference characters will be employed for like parts. Fig. 3 illustrates an elongated hollow member or head 56 preferably substantially as long as a fin 28 and-comprising a'tube or conduit cut away longitudinally from end to end to form a segmental opening, closed by a V-closure 52 provided with a plurality of small discharge openings or spray holes 53, with their axes substantially normal to the portion of the V-closure containing them. The closure 52 provides a V shaped recess 52 and the closure forms, in transverse section, an acute angle so that spray exiting from the spray holes 53 is directed upon a relatively small area of the trousers legs and, because 'of the acute angular formation and the companion acute angle formed by the trousers leg there is no large space traversed by the spray, and the spray does not escape readily and thus does not become wasted. Surrounding the inner faces of the closure 52 but spaced therefrom is an elongated conduit 54 smaller in diameter than the tube 5| and also cut away longitudinally as is the tube 5|. Both the tube 5| and conduit 54, with the closure 52, may be welded together at their joining portions. The outer and inner ends of the several associated tube 5|, closure 52 and conduit 54 are closed with a common suitable closure as a plate 55. Each plate 55, at one end of the tubes and conduits, is provided with an intake port 56 opening into the tube 5| and there is a suitable exhaust port'adjacent the opposite closure or plate 55. In addition, the end portion of a conduit 51 extends radially through each tube 5| and opens at a discharge port 58, into each conduit 54. It will be noted, in Fig. 3, that the apex of the inverted V closure 52 extends to this port 58, thus tending to divide the flow of fluid from the port into the substantially equal-volume streams. Because the structures C and D reciprocate transversely, it will be noted that flexible tubing 59 is disposed outwardly of the intake ports 56 (and open thereinto) and the exhaust 75 4 ports mentioned, adjacent the opposite closures or plates 55 open into flexible tubing 66.

The actuating means E for the means B and structures C and D may comprise the foot pedal 65, pivoted to the base member Hi and also pivotally connected with a link 66 which is pivotally connected to one end of a rocker arm 6?, pivoted to the upright l3 as at 68 and pivoted, at its other end, to a vertically-extending liner 69. The

latter, at its upper end is pivotally connected to a somewhat Z-shaped lever Ill, pivotally connected, intermediate its ends to the upright 3 at H, and at its inner end, pivotally connected to thadepending central arm 12 of a T-shaped member 13 with the horizontal portion or cross member of the member 13 rigidly secured to the two lowerheads 59. By means of a link 14, pivotally connected at its lower end to the lever 10, intermediate its ends and pivotally connected, as

at 15 to a somewhat Z-shaped lever 16 (inverted with respect to the lever 10 and substantially like the lever 19). At its inner end, the lever 16 is pivotally connected to the upwardly-extending central arm 11 of an inverted T-shaped member 5 18 with the horizontal portion of the member 18 rigidly secured to the two upper heads 56. Pressing down upon the free end portion of the foot pedal 65 will cause the lower heads 59' to ascend and the upper heads 56 to descend. In both cases 0 they will ascend or descend so that the outer ends of the paralleling flns 28 will enter the spaces between the closures 52 substantially as one fin 28 is shown'in-Fig; 3. This will bring the trousers legs in the areas where creases are to be made within this space mentioned.

A rod 8|] extends horizontally from the pivotal connection of the foot pedal 65 and base member Hi to the member 31 so that the latter is oscillated as the foot pedalfiS descends and is again raised.

5' The fluid-conveying means F for the means 13 crease definers 26. As has been stated, the other ends of these specific conduit-supports 29 are connected with the conduit-supports 29 of the lhe lower crease definers 21, as by the hollow flexible'U-sections 40, whereby there will be a circulation of live steam through each conduitsupport 29. Theopposite ends of the conduitsupports 29 of the lower crease deflners 21 carry the hollow flexible sections 4| and these connect with exhaust conduits 81. From each live steam conduit'b'ranch 86 extends a live-steam lateral 88 (by means of a suitable coupling 69) to the flexible tubing 59 of the tubes or conduits 5| of the upper heads 50, while suitable couplings 99 connect the conduit branches 86, by way of laterals 9|, with the flexible tubing 59 of the tubes or conduits 5| of the lower heads 50. The flexible tubing 60 conducts the exhaust from the four tubes or conduits 5| to a pair of exhaust conduits -92 to suitable connections'Sl (which connections also connect with the exhaust conduits 81 by means-of suitable couplings 93) and from these couplings 93 exhaust conduit sections 94 and 95 carry off the exhaust to be reconverted into steam.

Furthermore, the fluid-conveying means F includesa pairof conduits 96 for conveying live steam from the flexible tubing 59 to the two conduits 5'! of the two upper heads 50, there being laterals 9! from the conduits 96 to the two conduits 5'! or the two lower heads 50. Of course, there is no need for means to conduct any exhaust from these heads.

The blower and heater means H may comprise a conventional blower I having its exhaust mouth at I e! and exhausting air, under pressure; I into a conventional air heater I02 having: a heated air discharge end portion I03 including a mouth or port opening into a heated air conduit I04 discharging into thespace between the as-.

may be heated in any approved way, such as by a volume of the steam coming from the intake 85, since a pipe I05 may connect at the connection I 05, enter the heating compartment and the heat circulated along suitable laterals I06 and the cooled fluid exhaust through pipe assembly I01 to the connection 03 for discharge through the exhaust conduit sections 94 and 95. Suitable shutters or closures Hi8 and I0!) may be provided and interposed between the heater I02 and conduit I84. .The meansK may be supported by the wall II. i

Means K to regulate the flow of steam through the conduits extending to the conduits 54 in the heads 50 may be conventional e1ectric'ally-operateol valves H0, interposed in the tubing 96 and 91 and electrically connected witha conventional electric switch III carriedby the base member I0 and conventionally synchronized for activation upon rotation of the rod 80 as by a suitable conventional cam II2 carried by the rod 80 to rock with rotations of the rod to alternately open and close the switch.

From the foregoing it can be seen that after the trousers are positioned on the new presser, with the waistband secured about the band I5 andthe lower crease definers 21 lowered to render the legs taut, the operator then. moves the foot pedal 65, causing the four heads 50 to move toward the crease definers 2B and 2'! respectively to position them in the relative positions as shown in Fig. 3, whereupon the cam II2 will contact the activator of the electric switch II I to close the latter and this will cause the flow of current to cause operation of the valves IIO whereby they are opened and steam will flow through the valves and, consequently, out of the plurality of small openings or hole 53 causing the trousers to be steamed and the desired creases set. The blower I00 is thereupon started to operate simultaneously with closing of the valves Ilt, as the operator begins to release the pedal 65, and the heated air under pressure draws the steam from and dries the trousers. Further lowering of the pedal 65 causes the heads 50 to move away from the crease definers 26 and 21 and the lower crease definers 21 raised thus releasing the legs. band is then released from the band l5 and the trousers slid on the presser.

It will be noted that, at no time are the heads 50 in contact in any way with the trousers legs and there is substantially only line contact of the trousers and the blades 28 of the crease definers. Thus there will be no possibility of shine on the trousers due to the pressing machine operations. In other words, the heads 50 of the creasing means are out of contact with the trousers legs at all times including contact with the legs at the creases defined by the blades 28.
