IRONING MACHINE.

Application filed May 9, 1921. Serial No. 468,069.

To all whom it may" co a/0cm:

Be it known that we, WILLIAM G. Yarns and GEORGE C. Farsorrnn, citizens of the United States, and of the Republic of Germany. respectively, residents. respectively, of Cleveland, in the county of Cuyahoga and State of Ohio, and Lakewood, in the county of Cuyahoga and State of Ohio. have invented a certain new andnseful Improvement in Ironing Machines of which the following is a full, clear, and exact description.

The object oft-his invention is to produce an ironing machine of low cost and high efficiency; and particularly a machine with which ruliles and tubular garments, such as skirts, may be ironed by the same means which are employed in ironing fiat work.

The invention'consists in the construction and combination of parts shown in the drawings and hereinafter described and pointed ontdefinitely in the appended claims.

In the drawings, Fig. 1 is an end view of an ironing machine which embodies the. present invention; Fig. 2 .is a front elevation thereof;-Fig. '3 is a transverse sectional side viewthrough the ironing shoe and pressure drum, and Fig. 4 is a d'etachedview of the driving shaft and the part of the change speed mechanism mounted thereon.

A built up frame supports a'fixed 'hollow ironing shoe 12, the front operative face of which is curved in the usual way to substantially fita portion of the periph ery of the rotatable ironing drum 20. lVith-' in the shoe are means to heat its operative face, as for example, a long gas burner 13.

The ironing drum has at its ends trunnions 21, 22; and these are rotatably mounted in arms 23, 24-, which are parts of arocking frame, the other part of said frame being a rock shaft which is rotatably supported in hearings in the end members of the frame. These arms extend from the rock shaft forward and preferably at a slight angle upward so that the weight of the drum will tend torock the frame to carry the drum away from the shoe.'

The arm 23 at the left end of the drum (the opposite end to that at which the driving mechanism is-placed) is so constructed that it may move-out of supporting engagement with the drum and may also be moved away from the end of the drum so that a tubular garment, such as a skirt, may be slipped over the drum-,after which the arm may be returned to its drum supporting position with relation to the drum.

In the construction shown for attaining this result the arm 23 is formed with a LJ-shaped transverse notch'23 near-its end which furnishes thebearing forthe adjacent trunnion 21. This arm23 is bifurcated at its outer end and straddles the rock shaft to which it is pivoted on apivot pin 26- tilllttll extends diametrically through the s 1a 't.

The members of the frame are tied together near their front lower portion by the tie rod 40 to which a nonrotatableratchet wheel 41 is fixed. Adjacent this ratchet wheel a treadlelever 42 is mounted to rock on this tie rod, said treadle lever comprising the treadle arm 42 and an upwardly extended arm 42*. To this latter arm a. pawl43' is pivoted in position-t0 engage the nonrotatable ratchet wheel-41. The arm 42 of this treadle mechanism is connected with an arm 27 fixed to the rock shaft25 by alink is pressed yieldingly' against the-shoe. When by the rocking of the treadle mechanism this spring'44 has been put under'the de sired tension, the pawl 43 will engage a tooth in the ratchet and thereby the parts will-be held in this adjusted position. will be in this position when the ironingop eration is going on. the cloth to be ironed from the adjacent table and push it rearward andcause it to pass between the rotating ironing drum and the fixed slioe.

Near the front of the machineis a rocking pawl-release frame comprising two arms 51 which are loosely hung on the tie rod40 and are connected by a long footbar 52. A link 53 fixed to this bar 52 is connected-with the tail end ofthe pawl 43. By stepping on this bar 52 the pawl will be rocked so'that it will release its engagement with the ratchet 41 whereupon the treadle mechanism will be free to rock and allow the drum to move away from the shock At the rightend of the drum is the driving mechanism therefor. This includes of The parts The operator will take necessity a gear fixed to the drum trunnion and a driving gear 32 mounted in axial alignment with the rock shaft 25, said gear being movable in the direction of its axis into and out of engagement with gear 28. In the preferred construction, however, there are two gears 28, 29, of different diameters, fixed to the drum trunnion, and there are two driving gears 32, 33, of different diameters adapted respectively to engage the twogears 28, 29. The two gears 32, 33, are fixed to a sliding sleeve 31 which is mounted upon a shaft 37 which is mounted in axial alignment with the rock shaft 25. This sleeve is provided with a circumferential groove 3% for engagement by a lever, which is not shown, whereby the sleeve may be moved lengthwise of the driving shaft to cause gear 32 to mesh with gear 28, or gear 33 to mesh with gear 29, whereby the drum may be driven at either of two speeds. The distance between gears 33, is such that sleeve3l may be moved to a neutral position, in which neither of the gears 32, 33, may engage the associated gears 28, 29. By moving the sleeve from this neutral position in one direction to another the desired intermeshing of the gears 32, 33, with the corresponding gears 28 or 29 will be produced.

. A drum support 56 is mounted on the bed or table 11 of the machine frame in a position such that it may be utilized to temporarily support that end of the drum P which is supported by the pivoted arm 23.

It is preferably pivoted to the table so that when not in use it may be swung down out of the way when it is desired to introduce a tubular garment around the drum so that it may be ironed, this device is turned up to operative position and then the drum is allowed to swing down into engagement therewith. The rocking frame will then be still further rocked until the U-shaped notch 23 is withdrawn from the trunnion 21. When this has been done the arm 23 may be swung on its pivot 26 into a position such as to completely uncover the end of the drum, and permit the tubular garment. such as a skirt, to be passed over the end of the drum. WVhen this has been done the arm 23 will be swung into operative position, and the rocking frame will be rocked and the drum will be picked up by said rocking frame in readiness to serve the purpose for which it is provided. I

Ofcourse, this support for temporarily upholding the drum while its end is no longer supported by arm 23, may be omitted, because the operator can with one hand swing the arm 23 out of engagement with the drum trunnion, and may at the same time with the other hand hold up the drum so as to permit the tubular garment to be passed over: it.

It will be noted that the end of the drum with which arm 23 engages is, even when said arm is engaging the trunnion, practically free and open so' that a rutlle may be introduced between-the end of the drum and shoe and iron between them.
