APPARATUS FOR PRESSING TUBULAR GARMENT ELEMENTS Filed May 51, 1938 2 Sheets-Sheet 2 Job]? If LJ By j zlf AiZW-a I V WWMFA Patented Nov. 21, 1939 UNITED STATES.

My present invention relates to apparatus for pressing tubular garment elements such as overalls or trouser legs and shirt sleeves, and generally stated consists in novel devices, combination of novel devices and arrangements of parts here inafter described and defined in the claims.

More specifically stated, the present invention is of the general type disclosed and claimed in prior art Patents 1,937,656 and 2,022,210, the former of which was issued jointly to myself and George H. Leef on December 5, 1933 and the latter of which was jointly issued to myself and said George H. Leef on November 26, 1935. More particularly the present invention is in the nature of an improvement on the garment pressing apparatus disclosed and claimed in plication S. N. 162,585 filed September 7,1937 and entitled Method of and apparatus for pressing tubular garment elements.

In the commercial form of the garment pressing device of the prior patents above identified and in the pending application referred to, each ironing device comprises a relatively fixed hollow boot and a relatively movable hollow boot; and in the structure of the pending application, as an important novel feature, a rotatable ridge rod or shaft is applied longitudinally of the exposed edge of the fixed boot for the purpose of rotatably shifting the garment leg or sleeve on the boots thereby giving a more complete ironing action. My present invention is directed to improved means for operating the rotatable ridge rod or shaft, and more particularily for simultaneously rotating both of the ridge rods of. two ironing devices located in such juxtaposition that both legs of a pair of trousers or both arms of a shirt may be simultaneously ironed.

The complete machine involved in the present invention is illustrated in the accompanying drawings wherein like characters indicate like parts throughoutthe several views.

Referring to the drawings:

The mechanisms shown in the present application for moving the relatively movable ironing boots 'in respect to their emu-operating fixed boots my pending ap-' PATENT OFFICE 1 APPARATUS. FOR PRESSING TUBULAR GARMENT ELEIVIENTS John H. Leef, Minneapolis, Minn. Application May 31, 1938, Serial No.-210,951 17 Claims. (01. 223-73) illustrated in this application are so closely like mechanisms for thesame purpose disclosed and claimed in my companion application, executed of even date with the present application, that the corresponding parts are hereinafter illus-;. trated by the same characters.

Referring particularly to Figs. 1 and 2, the numeral Hi indicates a table top or frame on. which the ironing devices are mounted. Each ironing device involves a hollow fixed boot II and! a relatively movable boot [2. The boot II is rigidly anchored on the table top. A relatively movable boot i2 is connected to the co-operating boot II for movements toward and from the same preferably by a leaf-like link M, the lower end of which is pivoted to the base of the co-operating boot I l at l5 and the upper end of which is pivotally connected to the intermediate portion'of the movable boot l2 at "5.

In cross section the boots ll and I2 somewhat closelyapproach triangular form but with rounded outer sides in engagement with the garment. The fiat adjacent sides of the co-operating boots II and I2 have notthe same longitudinal curve or form, and the fiat surface of the movable boot-l2 has greaterlongitudinal curve than does the flat surface of the co-operating boot II.- This is to permitrocking movement of the boot l2 on pivot l6. even when the two boots are close together or in contact, and thereby better adapts the boots for complete contact with the garment leg or sleeve. -In Figs. 2 and 3, a shirt or garment sleeve is indicated by A but. it will, of course, be understood that thegarment legs might have'been shown. Intermediately pivoted on a cross rod or bar I! rigidly secured to the legs of the table I 0 is a foot pedal l8,- which as shown, comprises laterally spaced rigidly secured bars and a foot piece IS. The inner ends of the barsof thefoot pedal l8 are connected, one to each of the movable boots [2 and connecting rods 20.- Pivoted to the forwardly and outwardly projecting portion of the foot pedal I8 is a depending lock dog 26, the function and action of which is fully disclosed in my above referred'to companion application. I

Steam or hot air will be supplied to the interiors of the boots. As shown, heating medium is supplied to the fixed boots through fixed pipes 32 and to the movable boots through pipes 33. These particular pipes form no part of the present invention and hence may be further ignored.

.is provided with a semi-cylindrical longitudinal groove 35, see particularly Figs. 2 and 3. To give this ridge rod or roller traction on the garment leg or sleeve it is provided with a rough exterior surface such as produced by corrugations or' knurling. At its extreme upper end the roller 34 is provided with a trunnion or reduced portion that is journalled in overlying lug portion 36 of the boot, see particularly Fig. 1. At its lower end the roller 34 is provided with a reduced portion 34a that is extended through the base flange of the fixed boot and down through the top of the table H]. In this twin or duplex ironing device the ridge rods or rollers are applied to the fixed boots of both ironers and the depending portions 34a of said rollers or rods are provided with sprocket wheels 31 over which a sprocket chain 38 is arranged to run so that simultaneous rotary movements will be imparted to both the ridge rods or rollers. The said ridge rods or rollers are applied to the fixed boots rather than to the movable boots because of the impracticability or difficulty in applying them to the movable boots. Also, the sprocket and chain connects are afforded simple and eflicient means for connecting the two rollers for simultaneous rotation. A power device is preferably employed to impart the simultaneous movements of the ridge rods or rollers. This power device is shown in the form of a cylinder 39 in which is a pistons). The cylinder 39 here shown is provided at one end with a caplike head 4| and at its other end with a similar cap-like head 42. This piston 40 has a stem 43 that works through the head 4| and is provided with an upturned end that is rigidly attached to one of the links of the sprocket chain 34. A coil spring 44 placed around the piston rod 43 nor- [mally holds the piston 40 in the position shown in Fig. 4, and the stem 43 in a position shown in "Fig. 2. The piston 40 will be forced forward in the cylinder under the action of compressed air or steam supplied through a pipe 45 that is secured to and delivers through the head cap 42. The supply of compressed air or steam in pipe 45 and the discharge of the same therefrom is regulated by a three-way valve. This valve, as shown, involves a casing 46 and a segmental core 41, which latter at its projecting end, has an operating handle 48. Compressed air or steam is supplied to the valve casing 46 by pipe 49 which leads from a suitable source of compressed air or steam. The numeral 50 indicates an exhaust pipe that leads from the valve casing 46.

When the valve core 41 is set, as shown in Fig. 2, cylinder 39 at the'rear of piston 40, will be connected to the atmosphere, but when the valve core is turned about degrees in a clock-wise direction, cylinder 39 will be connected to the source of fluid pressure supply. When the cylinder 39 is open to atmosphere, spring 44 will restore the piston and hence the sprocket and chain connections to the position shown by full lines in Fig. 2. Under the above operations, the feed rollers 34 will simply be rotated backward. To impart the above step or steps of rotation to the feed rollers 34, it is not necessary to release the pressure of the shoes on the garment legs or sleeves. In fact, considerable pressure is necessary on the roughened feed rollers to give the traction necessary to impart the steps of rotation to the garment sleeves or legs.

By reference to Fig. 3 it will be noted that the outer surfaces of the feed rollers 34 complete the arch or curve of the shoes, but when a garment sleeve or leg is ironed by the first application of the ironing pressure, it will be ironed smooth except for that portion that spans the grooves 35, and when the garment sleeve or leg is given the second step, all that portion that was not completely ironed and that is in contact with the roller or spanning the gaps of the grooves 35 will be completely ironed against smooth surfaces of the shoes. Of course, the movement imparted tothe feed rollers should be suflicient to move the garment sleeve or leg the distance above indicated. This amount of movement may be determined by the length of the cylinder 39 and the piston rod. That end of the cylinder that includes the head 4 lshould be vented to atmosphere so as to permit return movement of the piston under the action of the spring 44: and this may be done by leaving clearance between the piston rod and the passage therefor in head 4|.

In the foregoing it will be understood that the device described is capable of modifications within the scope of the invention herein disclosed and claimed.
