The machine shown herein as illustrative 01' one mode of practicing this invention comprises a heated shoe l and a padded roll 2, the latter 01' which is supported by a mechanism housing 3. The shoe is carried on the end of a tubular member l which at its other end is secured in the housing member 3. The aforesaid parts are of unitary construction and they may be conveniently supported for use on a stand such as that illustrated in Figure 1 which comprises a rectangular top member 5 having a leg 6 positioned at each of its four comers, the legs being provided with casters 1 to facilitate the movementof the machine about from place to place. A horizontal wall 9 divides the gear case into upper and lower compartments. The upper compartment houses the gearing, and the lower compartment, which is open at its bottom, provides-an enclosure for the driving motor of the machine.

Interconnected reinforcing members 3 and Ill engaging the lower parts of the legs are provided to rigidly secure these parts. of the machine to each other. Pivoted to one end .of the machine is a drop leaf I l which may be raised from the position shown in Figure 1 to provide an extension for the work receiving base or top member 5 of the machine. Suitable switches are provided for controlling the supplying of electrical current to the driving member of the machine and to the heating element of the shoe, the operating member of the shoe heating element switch being indicated at I! and the operating member of the motor switch being indicated at l3.

The shifting of the roll and the rotating of the roll are controlled by means of a manually operated member l4. This memberis connected to a knee control member l5 in such a manner that the machine may be operated either by the hand or by the knee at the option of the operator. The control member I6 is provided for disconnecting or for preventing the connection of the roll rotating mechanism to the roll so that the machine may be used for pressing and other received a tube 20 which projects into the roll- 2 and extends throughout the greater part of its length. A second hollow boss 2| is formed on the housing and in this boss there is received in a flxedmanner the tube 4 which is provided for carrying the shoe.

The roll of this machine may be formed from a hollow sheet metal drum. 22 on which suitable padding 23 is wound. The end of the roll nearest the gear case is provided with a bearing member 24 which rotates in contact with .the rim of a cup-shaped bearing and supporting member 25.

The opposite end of the roll is provided with a closure cap 26, the central portion of which carries a coupling member 21. This member is secured in a fixed manner to the center of the cap 26 by means of a bolt 28. An arm 30 having a bearing 3| for receiving the coupling member 21 is provided for supporting this end of the roll.

The gear case 3 is provided with a third hollow boss 32 through which a shaft 33 projects. The remote end of this shaft is journaledin a bracket 34 fixedly carried by the end of the roll supporting tube 20. The arm 30 is pinned at 35 to this end offthe shaft. At the opposite end of the shaft 33 a collar 36, rigid with the cup-shaped member 25 is secured to the'shaft by means of a pin 31. From the foregoing it is apfrom the shoe l. The means for effecting such movement of the roll will be described in detail I presently.

As a means for rotating the roll there is provided a drivingshaft 38 having a pin 40 in its outer end which engages in slots formed in the end of the coupling 21. The opposite end of this shaft is provided with a pin M which is received in' slots formed in a coupling member 42. This member is pinned at 43to a stub shaft 44 which is journaled in a hollow boss 45 formed in the gear case 3. The shoe I is supported at a point intermediate its length by means of a flat cantilever spring 46 carried in a fixed manner by the tube 4. This spring provides for the yielding engagement between the roll and the shoe when with a strap 52 for receiving an eccentric 53 which is carried by a clutch mechanism mounted for rotation about the axis of the stud shaft 54. One end of the stud shaft is journaled for rotation in a hollow boss 55 carried by the gear case. The opposite end of the stud shaft is journaled in a suitable bearing formed in a bracket 56 which is removably secured to the gear case by means of screws 51.

A worm gear 58 is mounted for rotation on the shaft 54-. Coaxial therewith and fixed for movement with this gear is a pinion ,30 which is provided for driving the gear 5| through an idler gear 62 which may be moved into and out of engagement with the pinion 3|). The pinion gear 6|! has an integrally formed axially extending sleeve or collar 59 with an intermediate part of reduced diameter about which the gear 53 is cast and thus fixedly secured with respect to the pinion 60. The gear-6| is fixed toone end of the roll driving shaft .44. This shaft is joumaled in a suitable bearing 33 formed in the member 56.

Suitable means which will be described in detail presently are provided for revolving the eccentric 53 about the axis of the shaft 54 onehaif turn for each time either one of the control members l4 or 15 is operated. This operation of the eccentric alternately shifts the 'roll into and out of engagement with the shoe. When the roll is shifted against the shoe the idler gear 62 is dropped into engagement with the pinion 50 and in this manner the roll is rotated. When the eccentric is operated to shift the roll away from the shoe the idler gear 32 is automatically disengaged from the pinion 63 and the rotation of the roll is thus stopped.

An electric motor- 64 provides the source of power for the operation of .the machine. The

motor end caps 65 and 66 are provided with an- 88 which projects from the gear case.

gage with corresponding surfaces formed on the blockand they prevent rotation of the motor in the block 18 and also prevent the rotation of the block with respect to the straps II.

This arrangement provides an inexpensive and effective means for supporting the motor so that it is electrically insulated from the rest of the machine. The rubber blocks prevent the transmission of motor noises and vibrations to the rest of the machine and thereby serve to render this machine exceptionally quiet in operation. The base is cut away so that the motor 84 may be dropped therethrough upon the removal of the bolts 12 and the cross member 15 which carries the weight of the motor. The rubber blocks I8 are of such size so that they are put-under slight compression when the bolts I2 are tightened and thus firmly grip the motor.

The armature shaft 16 of the motor carries i a fixed manner a belt pulley TI. This pulley engages with a' belt I8 which serves to transmit the power of the motor to a mechanism pulley 18 located thereabove. It is preferred to form the belt 18 from an electrically non-conducting ma: terial so that the motor is electrically insulated at all points from the rest of the machine.

The pulley I8 is carried on the end of a shaft The other end of the shaft is received in the bearing pro- .abuttingthe face of the boss 83a of the gear case. The worm-is submerged in lubricant and the bottom of the worm gear normally extends a slight distance belowthe level of lubricant so that j duringthe rotation of the worm and gear,

- lubricant is piled up in the pocket formed bythe plate 83 and the boss 83 and in the space between the worm gear and the plate 83 whereby it is transferred to the worm gear 58 in considerable quantities and thus carried to the gears and bearmgs in the upper part of the gear case.

The worm 82 meshes with the worm gear 58 which is journaled for rotation about the axis of the shaft 54. The gears 88, GI, 82, and 58, have been previously described in connection with the description of the'parts shown in Figure 2. The supporting member 84 of the gear 82, is journaled for movement about the axis of the shaft 44. The gear 52 is rotatably carried bya stud 85 which is rigid with the supporting member 84. The supporting member extends for some distance beyond its gear and, at its end it is provided with a foot 88 which is engageable by a cam 81 carried by a pin 88 rotatably traversing the front wall of the gear case.

At the other end of the supporting member 84 there is provided a laterally extending sleeve 84 which is rotatably carried by the shaft 44. The

end of the sleeve remote from the member 84 car-' ries a radial projection 84 adapted to be engaged by the upper edge of the connecting rod 5|, asshown in Figure 4, to effect the disengagement of the gears 68 and 62 and thus to disconnect the driving connection of theroll when it is moved away from the shoe to the position shown in Figures 16 and 17. Similarly when the roll is moved into contact with the shoe as shown in Figures 18 and 19 the rod 5| moves away from the projection 84 as shown in Figure 5 and the- 'gear 82 can then dropinto mesh with the gear 68 and thus drive the roll.

Exteriorly of the gear case the control lever I6 is pinned at 88 to the bearing pin 88. When the control lever I6 is in the position shown in Figure 3, intermeshing of the gears 68 and 62 is prevented and when the control member is in the position shown in Figure 5 the gear 82 may be thrown into and out of mesh with the gear 68 by the elements which have been described. A spring 8| is carried in the outer end of the member 84- for the purpose of urging this mem-, her in a downward direction.

The starting and stopping of the rotation of the roll and the shifting of the roll about the axis of the shaft 33 is effectedin a controllablemanner by means of the clutch mechanism best shown in. Figures 7 to 11 inclusive. This clutch comprises a driving member 82 and a driven member 83. The hole 83' in the driven member. is provided for facilitating the machining of this member. The driving member 82 isfixedly secured to the worm gear 58 by means of rivets 84.

*The worm gear and the associated clutch part a are journaled for rotation on the shaft 54. The driven clutch member 83 is fixed by means of a pin 83' for rotation with this shaft and suitable rivets such as 85 are provided for securing the eccentric 53 to the driven, clutch member. .The

horizontal shade lines in Figures 4, 8, and 11 indicate the rear wall of the cup-shaped clutch member 82 and in Figure 11 the vertical shade lines indicate the edge of the annular recess formed in the driven clutch member 83 for the accommodation of the' clutch control members illustrated in Figures '7 and 8.

The driving clutch member has a smoothly finished rim portion 85. The driven clutch part 83 is provided with cam surfaces 81 and 88. Rollers I 88 and I8! are carried between the cam surfaces 81 and 88 and the rimportion 88 of the driving clutch member 82. These rollers are urged into clutching engagement with the respective clutch parts by means of springs I82 and I83. As viewed in Figure 9 the driving clutch part 82 normally rotates in aclockwise direction. For such movement of the clutch part 82 the roller l8l serves to provide engagement between the driving and the driven elements of the clutch. The reversely'acting roller I88 is provided to prevent the driven clutch from overriding the driving clutch part as might occur when the roll is occasioned by reason of the tension in the spring 48 which carries the shoe I.

A clutch operating member comprising a pair of arms I84 and I85 is pivotally carried by the shaft 54. These armsare provided for throwing the roller l 8l out of clutching engagement with the driving and the driven parts of the clutch. This part of the clutch is constructed in the manner shown for the purpose of preventing the partial engagement of the clutch subsequent to its release with the consequent frictional drag and the possibility of overheating and burning out of the clutch parts.

In the assembled relation of the clutch parts as shown in Figure 9, a small compression spring H4 is' interposed between the operating members I84 and I85 to maintain these parts separated from each other. member I 84 has an extension I81 with a bent over part I88 which is provided for engagement The roller controlling with stops H and III carried by an annular clutch controlling member II2 surrounding the clutch parts.

From a consideration of Figure 9 it will be seen that when the control member II2 is depressed the member I04 will be released for movement and upon engagement oi the clutch it will make approximately one-half turn whereupon it comes into engagement with the stop III. When this takes place the member I04 is held stationary and the roller contacting element II3 of the member I is resiliently pressed against the roller IN by means of the spring II4.

When suflicient power has been built up in the spring H4 or when the member I05 comes into positive engagement with the element I04 disengagement of the clutch takes place and after the initial disengagement of the clutch roller IN the spring II4 snaps the roller completely out of engagement with the cooperating surfaces ofthe driving and driven clutch parts and holds the roller in. this position until the clutch operating member is again depressed. It should be noted in this connection that the spring H4 is much stiffer than the spring I03 in contact with the roller IOI so that there is no tendency on the part of the spring I03 to move the roller into engagement with the cooperating clutch parts when the operating members I04 and I05 are held stationary against one of their stops H0 or III.

The operating member 'l I2 is provided with bent over portions II5 and H6 which engage the side of the clutch part 92 and serveto guide the member H2. The upper part of the member H2 is connected to a rod II1 which projects through the upper end of the gear case and is secured thereat to the manual control member I4. This member is operatively connected to a knee operated control rod II 0 which projects through the gear case and it is surrounded by a tube I20 to prevent the escape of oil or grease at the point where the rod enters the gear case. The control rod H1 andthe associated clutch controlling members are maintained in the position illustrated in Figure 9.by means of a spring I2I.

The control rod I I8 is articulated by means of a pin I22 to a cam I23 which is pivoted at I24 to a supporting member I25 secured to the underside of the base member 5. One end of an operating lever I26 engages the cam surface of the member I 23. This lever is guided for movement in a channeled member I21 and at its opposite end it is pivotally secured by means of a bolt I28 to a lever I30 which is pivoted at I3I to a bracket I32 carried by the underside of the machine base. The other end of the lever is provided with the bent over portion I5 by means of which the lever may be conveniently operated by the knee of the operator for effecting the operation of the clutch membersand the consequent starting and stopping of the rotation of the roll and the moving of the roll and shoe into engagement with each other. A coil spring I33 is provided to urge the lever I30 in a direction away from the cam I23.

The shoe I is electrically heated by means of an electrical resistance heating unit I34 which is located in position to heat the ironing face I35 of the shoe. Suitable heat insulating material I36 and a cover I31 are provided for directing the major part of the heat to the working face of the shoe and for maintaining the rear face of the shoe as cool as possible.

A pair of supporting ears I30 and I40 rigid with the shoe and projecting rearwardiy therefrom are which is fixedly secured to the shoe supporting tube 4. The bracket I43 is fixedly-secured to the base of the machine by means of abolt I44. The shoe is provided with an arm I45 engaging a small coil spring I46 carried by an adjustable bolt I41. This bolt may be adjusted to set the shoe at the proper angle with respect to the roll 2 and the cantilever spring 46.

The lower end of the cantilever spring loosely receives a bolt I40 carrying a spool I50 held against the head of thebolt by means of a spring I5I. The spool is adapted for engagement with the cut-out portion I52 of a safety release lever I53 which is pivotally secured to the cantilever spring 46 by means of the bolt I54. The operating handle I1 is located at the upper end of the release lever. This arrangement is provided for quickly breaking contact betweenthe roll and the shoe or for moving the shoe still further from its retracted'position with respect to the roll .for cleaning and other purposes.

The operation of this device is apparent from a consideration of Figures 14 ,and 15, Figure 14 showing in full lines the shoe and roll in their operative positions and in contact with each other and in the dotted line position in Figure 14 the shoe is shown in its released position which corresponds to the position occupied by the elements in Figure 15. The bolt I provides a means for readily adjusting the tension of the spring 46.

The electrical controlling elements of the machine are grouped together in a single structure comprising a box-like case I50 having a cover I51. The aforesaid parts are formed of a suitable dielectric material and constitute a switch housing and terminal housing for the control switches and lead wires of the machine. The case is arranged to be secured-to the base member 5 by means of two screws I52, I 52. A second cover I53 is provided for holding the terminal parts of the conductor cables in place and for covering the contacts to which these wires are connected.

A cable I54 having conductor strands I 55 and I56 is provided for connecting the machine to a source of electrical current supply. The end of the cable remote from the machine is provided with a connector plug (not shown). A flanged rubber sleeve I51 is vulcanized to the end of the cord I54 to provide a strain relief and to also provide a means for its securement in the case I50. The ends of the supply cable strands I55 and I56 are connected to terminals I58 and I60.

A conductor cable I6I is provided for connecting the motor 64 to the source of electrical current. The conductor strands of this cable are connected to terminals I62 and I63. This cord is likewise provided with a rubber strain relief I64. The heating resistor 01' the shoe is connected to the current supply line by means of a cable I65 surrounded by flexible metal sheath I66. This cable is likewise provided with a strain relief I 61 and its conductor strands are connected to the terminals I60 and I10.

The terminals I50 and I60 provided for connection to the current supply line are connected at their upper ends to conductor bars "I and I13. The conductor bar I" connects in series the terminals I60, I60, and I62, and terminates in one of the contact elements. I12 of a light socket. The other terminal of the current supply line is connected to a'conductor I13, one end 01 which is connected toone side I14 of the shoe heating switch is connected to the terminal III! by a con ductor I'II the last named conductor being also connected to the other contact I18 of the light bulb socket. This socket is adapted for reception of a pilot lamp I88 and it is connected in parallel with the circuit of the heating resistor.

01' the shoe so that when current is supplied to the shoe heating element the electric light burns and indicates that this element is in operation. A red glass cover I8l' is carried by the cover plate II over the lamp I88 so that the operation of the lamp may be readily observed.

The shoe heating element and motor switches are ,of conventional design, having conductor bars I82 and I83 and associated snap-over mechanisms I84 and I 85 by means of which the switches may be shifted with a snap motion to open or closed position by means of the switch operating members I2 and I3. By use of a unitary construction of the type disclosed it is possible to collect in one housing most of the electrical parts of the machine thus simplifying the initial assembling cost of the machine, greatly simplifying servicing problems, and at the same time providing a compact and neat arrangement for such elements of the machine.

Furthermore it is to be understood that the particular forms of apparatus shown and described, and the particular procedure set forth are presented for purposes of explanation and that variousmodiflcations of said apparatus and'procedure can be made without departure from the invention as described in the appended claims.
