1 entalities. for supporting the ironing parts (Figure l) consist ci a table having a top ll and end nges t, to which are attached legs t by means oi bolts t. The legsare braced by means of end braces t and Va rear brace t. Sup- 35j ported beneath one end' oil the table is a motor l, held in spaced relationship near the table by means of scers t through which screws t pass for supporting the motor on the table.

The motor shait is provided with a motor m coupling it by which the motor is operatively f connected to a worin shait ior transmitting power to the moving parts ci the ironing machine. in one corner and on top of the table is a name-plate it, which has therein a switch it for cutting the current on and od oi the heating unit.4 The motor is provided with a lead cord il, which on its -end a plug for connecting the cord to a suitable sociret in the vExtending from the switch are wires it iorfconducting current to These es extend through a derdble conduit it, which has Aone end suitably attached to bach oi the shoe.

i r11 ol the table top is a gear a key 45.

"screw 25.

casing ill integral with and extending upwardly from the gear housing floor 22. Immediately beneath the bearing 20 and around the worin shaft are leather` washers 23, which have beneath them a retaining washer 24. The bearing 23 is held within the casing 2| by means of a set Around the shaft I3 and resting upon the bearing 20 is a thrust washer 23, which has above it a worm shaft collar 21 attached to the shaft by means of a pin 23. The worm of the shaft is indicated by lthe numeral 29. 'Ihe upper end of the worm shaft is supported by means `of an arm 3|) which extends from the rear of the housing toward the open side 1 thereof. The worm 23 engages a worm gear 3| on theshaft 32 and has integral therewith a pinion 33Y which meshes with a gear 34. The shaft 32 is supported by means of a boss in one side of the gear housing.

The gear 34 is loosely mounted upon a drive or roll shaft 35 and is held against longitudinal mhcvelsient on the shaft by means of 4a cotter p housing and adjacent the top thereof (Figure 3) is a cone-shaped projection 31, which has therein a cylindrical sleeve 33. This sleeve extends through a back 33a of the housing and;y has attached thereto a roll tube 33. Within this roll tube 33 is a collar 4l1secured thereto by a pin 4`l. This collar is located around the roll shaft and between the roll shaft and the roll tube, and serves as a retainer for a bearing 42 located -between the roll shaft and the roll tube.

Adjacent the bearing are felt washers 43. The roll shaft has .thereon a clutch member 44 ladapted to move longitudinally thereof and to rotate therewith through the instrumentality of The clutch 44 is adapted to engage a clutch 46 on the hub part of the gear 34 so that when these clutch elements are inlengagement the rotation of the gear 34 will cause the shaft 3l to rotate. "The clutch 44 ,is provided with a groove 41 to receive the yoke end 53 of a lever 43 pivoted at the point 43 on the floor of the housing. s This arm is acted upon by means of a spring I tending to hold the clutch members in engagement.

'I'he roll shaft 35 and the roll tubehave mounted thereon a roll 52 (Figure l), which is hollow and cylindrical and has at each end a cup-shaped end member 53, each of which has an outwardly extending flange or cylindrical part `54 to which a tubular member 53 is attached. Extending inwardly from each end member and in a direction opposite that of the flange 54 thereof, is an inner tubular member Il'adapted to rotate around the roll tube and supported on the roll tube by means of roller bearings 51.

The roll shaft 35 extends longitudinally mrough the roll and is attached at its free end Extending rearwardly from the gear A sion 33 between the shaft and the end of the roll tube remote from the'gear housing. The roll locking knob 53 is attached to the end member`53 remote from the gear housing by means of a drive pin 60a. This end member has its tubular member 56 provided withroller bearings 51 between it and theA roll tube. The roll shaft is provided with a spiral groove 6I for the purpose of transmitting lubricant from the gear housing to the endof theroll tube remote from the housing. Around the roll 52 are layers of material for building up the circumferential part of the roll. There is, rst, a pad- 62 about which there is an under cover 63 and an outer cover ,84. Located in the gear housing and adjacent the floor thereof (Figures 2 and 3) is an inwardly projecting boss 55 having a bore which supports a control shaft tube 31, having therein a control shaft 33. Around the shaft and between the shaft and the) control tube is an oil seal packing ring 33 of any suitable and conventional type. Secured to the outer end of the control shaft 35, as by the pin 69a, is the hub of a cam lever 33 (Figures 2 and 3.). On the free end of the arm 63 is mounted a bolt 10. which has thereon a head for engagement with a cam surface 1I on the lever 48. The lever has thereon a projection 12 so `arranged that the head "of the bolt cannot pass from the lever in its movement toward the top wall of the gear housing.

One end of the control shaft 63 is supported by the structure just described, while its otherend is `supported by means of a bracket 13 (Figure 1) suitably attached to the top of the table. 0n the end of the control shaft beyond the bracket 13 and held thereon by means of' set screws and a collar 15 is the hub 14 of a downwardly extending arm 11,- which is longi justed with relation to the pressure lever so it may extend either to the righthand side or t0 the lefthand side of the pressure lever. To the arm 11 (Figure 4). is attached one end of a spring 33 which tends to hold the foot'rest in its forward position. Extending upwardly from .the hub 14 is an arm 34 which has.attached thereto one `end lcf each of ytwo springs, one a pressure spring 35 and a second pressure spring 33 (Figure 4).

The hub 14 is provided with a socket 14a arranged to receivey a plunger 34a, which 'is reciprocably mounted in a bore in the bracket 13. urged toward the socket 14a by a spring 34h and operated by means of a knob 34e (Figure l). I'his plunger 34a projects beyond the lug supporting it and in the path of tnearm 34 for holding this arm 34 in position with relation to the roll. By withdrawing the plunger 34a from the socket 14a the arm 34 may be moved backward, carrying with it the shoe so as to provide a wider space between'the shoe and the roll. The second-spring 38 is jor the purpose of holding the shoe in .proper position when the shoe is withdrawn from engagement with the ironing roll.
