. In Fig. 1 of the drawings there is illustrated in perspective an ironing apparatus of the roll 30 type which includes a support 20, a transmission indicated generally at 22, an ironing roll 24 supported from the housing oi the transmission 22, an ironing shoe 28 mounted upon an arm 28 carried by the support 20, a control member 30 35 which is operable for controlling the operation of the ironing apparatus and a second control member 32 which is operable for changing the speed at which the roll is driven, or for disconnecting the roll from its driving mechanism so 40 that the ironer may be operated for pressing.

The transmission 22,'as illustrated, comprises a housing which includes an open-ended supporting member 3! rigidly secured to the support 10 in any suitable manner, a bearing plate 36 ior closing the end of the compartment 38 within the housing within, which the transmission mech anism is disposed, said bearing plate being detachablyand rigidly secured to the end iace'oi the support member 34 such as by a plurality of bolts 40, and an ornamental cap 42 which is adapted to cover the bearing plate 36. The ornamental cap 42 may beheld in place by a plu-v rality of springclips carried thereby and which are engageable with apertured portions of the bearing plate 36. The housing of the transmission may extend below the surface of the support or table 20 to provide a space or compartment 46 open at the bottom end in which a motor 48 for operating the ironer may be arranged. The motor 48 may be supported by the housing in any suitable or convenient manner.

The shoe 26 preferably is provided with a heating means therein and includes a polished metallic face 50 which is shaped to conform to the padded surface of the roll 24 and is coextensive in length therewith. The shoe 26 is carried by the arm 28 of a channel shaped bell crank lever 54 and to the upper end of which arm 28 the shoe is connected by means of a pivotal connection 56. The pivotal connection may include a horizontally disposed pin 58 passing through aligned openings in the upper end of the arm 28 and in a bracket 60 carried by the shoe 26. A spring clip 62 carried by the pin 58 has one end thereof engaging a portion of the shoe at 64 and the other end thereof engaging a portion of the arm 28 at 66 forflresiliently supporting the shoe from the armin the position illustrated in Fig. 6. The

arm 28 of the bell crank extends upwardly through the opening at the rear of the support 20 and midway between the ends of the roll 24. The support 20 may be provided with a pair of spaced downwardly extending brackets 68 carrying a pin I0 on which the bell crank lever 54 is pivotally supported by means of a hub 12 formed integrally therewith. That portion of the bell crank 54 below the surface of the support 20 extends horizontally and may be bifurcated to provide a pair of arms I4. Each arm I4 has associated therewith a coil spring 84 backed up by an adjustable, seat I6 provided by a washer held against upward movement by a nut 18 threaded on to a fixed post secured to a bracket 82, for resisting clockwise movement of the bell crank 54 about its pivot I0. A pair of nuts 86 may be threadedly secured to the bottom end of each post 80 and below each of the arms I4 to provide a stop for limiting the counter clockwise movement of the bell crank 54 about its pivot I0. The spring 84 provides a resilient stop for the shoe 26 and is adapted to permit movement of the shoe 26 relative to the roll 24 when the parts are in the position illustrated in Fig. 6 so as to accommodate material of substantial thickness between the surface of the padded roll 24 and face 50 of the shoe 26.

While the shoe is adapted to remain substantially in the position illustrated in Fig. 6 or 7, the pivotal connection 56 between the shoe 26 and its supporting arm 28 is such as to permit the shoe to be turned in a clockwise direction about the pin 58 to a position where the face of the shoe is disposed upwardly or in a substantially horizontal position so as to permit the shoe to be used for steaming purposes. The pivotal connection 56 between the shoe 26 and its supporting arm 28 also is such as to permit a slight amount of turning of the shoe 26 about a vertical axis in order that the face of the shoe may be properly applied to the surface of the padded roll 24 particularly under conditions where material is being passed between the shoe and the roll only at one end thereof. As the shoe is supported from a point centrally of the ends thereof, the pressure between the face of the shoe and the surface of the padded roll will be distributed substantially equally over the entire contacting surfaces.

The roll 24 may comprise a cylindrical metallic shell 88 covered substantially by padding 90 of substantial thickness and a smooth piece of fabric 92. One end of thelroll may be provided with a circular plate 94 having the outer periphery thereof flanged at 96 and welded or otherwise secured to the inside of the shell 88, while the center of the plate 64 may be flanged inwardly at 98 to provide a seat for a bushing I00 which is secured to flange 98 and is supported for rotation on a bearing I02 by'means of which one end of the roll is supported. The bearing I02 is provided by one end of a plug, the other end of which is seated within the end of a tube I04 and fixed thereto. A collar I06 and a nut I08 threaded into a suitable opening in the plug I02 may be utilized for preventing axial separation of the bushing I00 and bearing I02. The tube I04 extends along the axis of the roll 24 and approximately the length thereof. To the other end of the tube I04 '(Fig. 4) there is fixedly secured a circular plate IIO, the outer periphery of which is flanged to provide an annular bearing II2 which forms a seat for an annular bearing member II4 carried by the roll 24 adjacent the transmission end thereof. The tube I04 is held against'rotation, as will be hereinafter explained, and the roll 24 is adapted to rotate upon the tube I04 and the bearings provided thereby.

The housing of the transmission, as illustrated in Figs.2 and 4, is provided with an annular boss II6 which forms a socket or rigid seat for a supporting tube II8, one end of which may be press fitted into the bore of the boss II 6 and locked therein by means of a set screw I20. The outer end of the tube II8 which may terminate substantially centrally of the ends of the roll 24 and is adapted to provide a bearing seat I2I for an arm or member I22, the lower part of which is arranged to telescope the end of the tube H8 and the upper part of which may be bifurcated as at I24 and which bifurcations are provided with aligned bores I26 for receiving the tube I 04 and which tube I04 may be locked to the arm I22 by means of a pair of set screws I28. While the arm I22 is locked to the tube I04, the arm I22 is free to oscillate about the tube II8.

A roll oscillating tube I 30 extends through the tube H8 and at one end thereof is seated within a bore in the arm I22 and locked thereto by means of a set screw I32 while at the other end. said oscillating tube I30 is seated in a bushing at I34 arranged within the end of the tube I I8. The tube I30 is adapted to be oscillated, as will hereinafter be explained, for moving the roll 24 toward and away from the shoe 26.; While the roll will rotate about the axis of the tube I04, the oscillation of the roll about the axis of the tube I30 will cause the surface of the padded roll 24 to move into and out of engagement with the face of the shoe 26.

A roll driving shaft I36 extends axially of the tube I30 and at one end thereof-(Fig. 5) is provided with a pinion I38 fixed upon the shaft operatively engaging an internal gear I40 provided by a member I42 which is secured to the shell 88 of the roll for movement therewith, such as by means of one or more screws I44. The hub of the gear I40 may-be provided with a bearing member I46 which may be seated upon the outside of the tube I04 so that the gear I 40 in effect will rotate upon the tube I04. As the center of oscillation of the roll and the center of rotation of the pinion I38 coincide, the teeth of the pinion will always be in driving relationship with the teeth of the gear I40.

The roll oscillating tube I30 extends into the mechanism compartment 38 of the transmission housing and has there connected to it a sleeve I46 by means of a set screw H8 so that the sleeve I46 will oscillate with the tube I30. The sleeve is provided with an arm I50 (Fig. 8) connected by means of a pin the connecting rod I54 being connected to an eccentric I56 rotatable upon apfixed shaft I58. One end of the shaft in the wall of the transmission housing and the other end of the shaft I58 is supported by the bearing plate 36. The eccentric I56 is formed as a part of a membervwhich includes a hub I60 rotatable upon the shaft I58.

A worm wheel I62 (Fig. 2) driven by a worm I64, provided with a cylindrical hub I66 (Fig. 4) is rotatably mounted upon the shaft I58. The

I hub I60 of the eccentric I56 and the hub I66 of the worm wheel I62 are adapted to provide 9.

- cylindrical clutching surface for a spring clutch engaged in 8. notch in ates to transmit torque which includes a coil spring I68, one end I10 of which is turned radially outwardly to be seated between a pair of lugs I12 provided on a side of the eccentric I56. The other end of the clutch spring I68 is also turned outwardly at I14 and a circular plate I16 freely rotatable on the hub I66 of the worm I62 and held in frictional contact with an annular surface I18 on a side of the worm gear I62. The inside diameter of the clutch spring I68 may be finished and may be slightly smaller than the 'outside diameter of the hub I66 so that there is very slight frictional'drag betweenthe two parts during such time as relative movement therebetween takes place. The spring clutch including the parts I68, I66 and I comprises a form of a one way or over running friction clutch and operin one direction only. The plate I16 is provided with a pair of axially extending lugs I spaced degrees apart and adapted to be engaged by an end I82 (Fig. 2) of the control member 30..

During such time as the motor 48 is operating, the worm gear I62 will be continuously driven and the eccentric the control of the spring clutch from the continuously operating worm gear I62. As illustrated in the drawings, the spring clutch including the parts I60, I66, I68, "6 and I82 comprises what is commonly known in the art as an 180 degree clutch, that is, a clutch which will, upon engagement, remain engaged for 180 degrees of rotation and thereafter will automatically disengage. In the 'case of the spring clutch illustrated herein, the rotation of the worm gear I62 and hub I66 will tend to rotate the plate I16. However, as .the end I82 of the control 30, by engagement with one of the lugs I80 on the plate I16, holds the same against rotation, the spring I68 will not grip the clutching surface I66 and hence the eccentric I56 will remain stationary. As the spring I68 is coiled in the opposite direction in whichthe worm gear I62 rotates, rotation of the worm gear I62 will tend to cause the spring I68 to wind up or grip the clutch surface I66 due to the frictional drag between .the plate Il0and the side wall of gear I62 and the inside of the clutch spring I68 and clutch surface I66. The control member 30 which is pivoted at I84 to a boss on the inside of the transmission case isadapted upon operation to move the end I82 out from in front of the lug I80,

I52 to a connecting rod I54,

I58 is seated within a bore oscillate the tube I30, arm I22, tube I56 is adapted to be operated under and 2I8 are mounted thereon thereby permitting the plate I16 to be carried around with the worm gear I02 due to the frictional drag therebetween. As soon as the plate I16 begins to rotate with the worm gear I02, the spring I68 will contract and grip the clutching surface I66, thereby coupling the member I00, and the member I66 for driving the memberlll and the eccentric I56. The control member 00 is adapted to be operated simply by pushing the same and immediately thereafter releasing it. As the worm gear I62 is rapidly rotating, the lug I00 will begin to move. As soon as the end I02 of the control member 30 moves out from in front there- ,of, and as the control member is immediatelyreleased after actuation, the end I02 thereof will return to a position in the path of the lugs I00, but the lug I80 with which the end I02 was in contact will have been moved around with the gear I62 and the end I82 of the control 00 will be in the path of the second lug I00 upon the plate I16 thereby permitting 180 degrees rotation of the plate I16. So soon as the second lug I00 comes into contact with the end I82 of the control .30, the clutch spring I68 will unwind or release its grip upon the clutch surface I00 with the result that the eccentric I56 will immediately come to rest and the worm I62 will continue to rotate. Upon each actuation of the control 00, the eccentric I56 will move through 180 degrees of travel and will through the intermediary of the connecting rod or link I50 and the sleeve I40 I04 and roll 24 for moving the roll relative to the shoe.

In the position in which the parts are illustrated in Figs. 3 and 4, the roll is in shoe-engaging position; whereas in the position in which the parts are illustrated in Fig. 7, the roll has been shifted away from the.shoe. Upon each successive operation of the control 30, the roll will be alternately shifted toward and away from the shoe. 8

Referring particularly to Figs. 4 and 6, it will be observed that the worm I64 at its upper end is journaled in a bearing is journaled in a bushing I88. The bushing I00 is arranged within a bore formed in a wall I80 of g the transmission housing and the worm shaft is provided with a shoulder I82 which is adapted to be located by means of anut I84 threaded into a cooperative part of the wall I80 and rigidly held in place by means of a lock nut I96. The nut I94 and lock nut I96 provide a means for properly locating the worm with respect to the worm gear I62. The coupling I88 operatively connects the shaft of the worm to the shaft 200 of the motor. The motor 48 may be electrically operated under the control of a mechanically operated switch so that during such times as the ironer is not in use, the motor may be stopped.

One side of the worm gear I62 is formed to provide a part 202 of a dog clutch which may be referred to as the roll driving clutch. The other part 204 of the roll driving clutch is formed upon a hub 206 which is provided with a pair of gears 208 and 210, the clutch member 204 and the gears 208 and 2I0 being rotatable as a unit. The hub 206 is adapted to be shifted axially by a fork 2I2 for the purpose of engaging and disengaging the into the end of the roll oscillating tube I00 and pair of gears 2l6 for rotation relaextends therebeyond where a I86 and at its lower end the roll'driving clutch in engagement.

tive thereto. The gears 2I6 and H0 are in constant mesh with the gears 208 and 2I0 respectively, audit will be observed that the size of the gears is such as to provide two different driving speeds for the roll driving shaft I36. Clutch member 220 slidably keyed to the roll driving shaft I36 and disposed between the gears 2I0 and 2I8 forms part of a dog clutch which is adapted selectively to connect either the gear m or the gear m to the shaft m for driving the same. Gears 2I6 and 2I8 are each provided with a dog clutch member 222 cooperable with the clutch'member 220 for connecting either of the gears 2I6 or 2I8 to the shaft I36. The clutch' members 220 and 222, which may be designated as-the two speed clutch are adapted to be opv erated by a fork 224 (Figs. 2 and 6) engageable with the member 220 and slidable upon a rod 226. One end of the rod may be provided with a plurality of notches 226 (Fig. 2) and the shift fork 224 may be provided with a detent 230 for engagement with the notches 228 for locating the positions of the clutch member 220 and holding the in the selected position. The shift fork 224 is"adapted t4: be operated by the control member 32 which isfmounted ,upon a shaft 232 (Fig. 6) extending ;through a boss 234 in the front wall'of thejtransmission housing. Within the same, so. that upon movement of the finger of the control member 32 to the left from the position illustrated in Fig. 2, the shift fork 224 and clutch member 220 are shifted to selectively connect either of the gears 2I6 or 2I8 to the shaft I36. One end of the pin 232 may extend into a horizontal slot in the shift fork 224 so as to provide a guide therefor. In this manner the operator may select the speed at which the roll will rotate or may disengage the clutch member entirely so that the roll will remain stationary for pressing purposes or the like.

The shift fork 2I2 (Fig. 4) which is operable for engaging and disengaging the roll driving clutch 202, .204 is carried by a hub 240 fastened upon a slidable rod 242 mounted for axial movement in a pair of guides 244 formed on the inside of the transmission housing at the top thereof. The shift rod 242 is biased by means of a spring 246 confined between one of the guides 244 and a collar 246 held in place on the rod 242 by a pin 250 for holding the parts 202, "204 of The con-. necting rod or link I54 (Figs. '7 and 8) -is-formed to provide a cam 252 whichis adapted to engage one end of the shift rod 242, upon rotation of the eccentric I56, for shifting the shift rod 242 to disengage the parts 202, 204 of the ro'lldriving clutch when the roll is shifted out of ironing relationship with the shoe2 6. The spring 246 operates to e g e the roll'driving clutch when the cam 262 is moved out of engagement with the end of the shift rod 242, which occurs when -the roll 24 is being shifted into ironing relationship with the shoe. Thus the roll driving clutch is engaged when the ironing roll is shifted into engagement with the ironing shoe and is disen gaged when the roll is shifted out of engagement with the ironing shoe. If one of the gears 2I6 or 2I6. is connected to the shaft I36 through the clutch member 220, the roll 24 will be rotated about its own axis when the roll driving clutch is engaged, and the roll will be at rest when the 24 roll driving clutch is disengaged.

the housing, anarm 2361 is pinned to the shaft 232 and carries a pint; 238 which extends into: a vertical slot in the shift fork 224 for operating In operation, assuming that the motor is operating and that the roll is operated from the shoe as illustrated in Fig. 7, material to be ironed may be laid upon the upper portion of the roll in the proper manner. Operation of the control member 30 will cause the roll oscillating clutch to engage in order to fleet the shifting of the roll 24 into ironing relationship with the shoe. As a result of the shifting of the cam 252 during the shifting of the roll 24 into engagement with the shoe 26, the roll driving clutch 202, 204 will be engaged and, assuming the clutch member 220 is connecting one of the gears 2I6, 2I8 to the shaft I36, the roll will be rotated about its own axis and cause the feeding of the material to be ironed in between the face of the shoe and the surface of the roll. Subsequent operation of the control member 30 will effect the shifting of the roll out of engagement with the shoe and will also bring about the disengagement of the roll driving clutch.

If it is desired to use the ironing machine for pressing purposes, the control 32 may be opergaged.

Inthe modified form an... invention illustr'atedin" 9, the sametransmission mechanism, controls and otherparts of the apparatus illustrated in Figs. 1 to 8 may be used, the construction illustrated in Fig. 9 differing from that illustrated in Figs. 1 to 8 in the manner in which the ironing roll is supported and driven. In this modification a tube 3I8 may be rigidly secured within a socket 320 formed in the housing of the transmission, said tube 3I8 and the wall of the socket 320 being provided with an arcuate slot through which a pin 322 extends. The pin 322 at its inner end extends into and fits a hole in an oscillating tube 330 and at its outer end is threaded into a. sleeve 33I which has a hearing on the outside walls of the socket 320. A plate 332 is rigidly secured to a radially arranged face-of the sleeve 33I and at its outer end is formed to provide a bearing 333 upon which one end of the roll 324 rotates and is supported.

The tube 3I8 extends substantially the entire length of the roll and at its outer end is provided with an internal bushing 334 ,whichforms a bearand support at the outer end of the roll upon which is journaled a bushing 331 carried by an end plate 338of the roll. The outer end of: the oscillating tube 330 is provided internallywith a bushing 339 which forms a bearing for the end of a roll driving shaft 340 carrying a pinion 3 which meshes with an internal gear 342-connected to the 'shellof the roll 324 for driving. the same. In this case the supporting tube 3I0 extends substantially the full length of the roll and the axis of the tube 3I6 coincides with the axis of oscillation of the roll324. The roll driving shaft 340 is disposed upon the axis of oscillation of the roll 324 so that the pinion 3 will remain in engagement with the internal gear 342 at all times. The roll driving shaft 340 and the roll oscillating shaft 330 may be driven or operated as illustrated in the embodiments disclosed in In the modification illustratedin Fig. 10, a supporting tube 350 may be securely seated within a socket 352 formed on the transmission case with the tube 353 preferably extended substantially the length of the roll and located on the axis of the roll when the roll is in ironing relationship with the shoe. The outer end of the tube 350 carries an arm 353 which forms a guide and support for the outer end of a roll oscillating shaft 354, the end of the oscillating shaft 354 being provided with a crank 355 pinned to the shaft 354 and which crank 355 carries a bearing 356 similar to the bearing 336 and which forms a support for a bushing or sleeve 35'! carried by i the end plate 358 of the roll.

At the transmission end of the roll, there is secured within the end thereof a bearing member 359 which is journaled for rotation upon a bearing 360 carried by an oscillating plate 35I which is pinned to and supported by the oscillating shaft 354. The plate 36! is provided with a slot 362 through which the roll supporting tube 350 extends. The roll oscillating shaft 354 extends through a roll driving tube 363 which is journaled in a bearing 364 formed in a wall of a transmission case. Within the transmission, roll shifting mechanism like that illustrated inthe embodiments disclosed in Figs. 1 to 8 may be provided for oscillating the shaft 354 in order to move the roll toward and away from the ironing shoe. The roll driving tube 363 at one end is provided with a pinion 365 which meshes with an internal gear 356 carried by the bearing member 359 and at the other end the roll driving tube 363 may be connected to be driven by roll driving mechanism like that illustrated in Figs. 1 to 8 inclusive of the drawings. In this case or in the case of the embodiments illustrated in Fig. 9, the roll driving tube and the roll oscillating shaft are concentrically arranged and located upon the axis of oscillation upon the roll while the roll supporting tube 350 is not so located. The tube 350 may be located upon the axis of rotation of the roll when the roll is in ironing engagement with the shoe, although this is not essential.
