In the drawings, the machine is showrras rising: a base In, T refer-e151? hollow emf 13 1 1gan? opening for receiving an electm ure entitle m1 for supplying lectricity to the roll motor emu ironing-shoe.

The: rotat-iom of: the rollismostconveniently aecomplishem by means of an electric motor housed within theroll! itself andi supplied with current btt cpnduetors leetding-- thereto? through thereof, While Within thezpedestall one of the hollow arms of yoke 2|, and the circuit is controlled by means of a suitable switch 46 mounted on yoke 36 and whose operating lever 41 is spring biased to closed circuit position. This lever 4'! lies in the path of movement of a. lever I 48 pivoted upon the brace member as at M811, and has its free end below the switch lever 41.

Below the lever I48 is a plate I50 provided with a portion extending under the lever I 48 and formed with an inverted V-shaped portion l50a, normallylying in a notch in the under edge of lever I 28. This plate is fixed to the end ofthe lever M0. Rotary movement, therefore of lever I40, through the action of the V-shaped portion l50a and the notched lever M8, will lift the switch lever 41 to open circuit position.- With this construction, the motor may be kept idle or stopped when the roll is down, by merely rotating the lever I49 to one side or the other As stated above, in the present machine, the motor is mounted in the roll and this-construction is shown best in Figures 6 to 10.

In these figures, the roll 20 is shown as hollow and carried on suitable bearings 66 on the arms of yoke 2|. These arms-are likewise hollow and one of them, 2), is provided with an extension 2lc projecting into the roll and secured to a spider 6|, the arms of which extend for a short distance lengthwise of the roll and are fixed to a suitable clamping ring 52 which embraces and supports one end of the motor 63. The motor 63 has at its other end a suitable reduction gearing 64 from which extends a driving shaft 65 carrying at its end a thimble 66 fixed thereto by the pin 6? and having a suitable bearin such as the antifriction bearing 68, within the end of the yoke arm Zld. This thimble 66 forms a part-of a clutch mechanism adapted to connect and disconnect the roll 20 from the motor drive.

' The clutch comprises the thimble 66 which is provided with a plurality of radial holes for the balls 1B which in their outward position cooperatewith notches in a ring H fixed to the end plate 12 of the roll 29, but, in their inner position, allow the roll to turn freely about the thimble. These balls 18 are moved outwardly to driving position by the circular cam 15, thrust outwardly by the spring (8, which cam is'provided with a pin 16 extending through the end of thimble 66 into the yoke arm Zld, while mounted within the latter is a lever 79 adapted to push inwardly the cam 15 and allow the balls to drop into their holes in the thimble B6 and thus release the roll.

In order to prevent the balls flying out under centrifugal action when not being urged out by the cam, a suitable spring 89 is mounted on the thimble 66 in such fashion as to press the balls inwardly when the cam has moved from behind them.

The lever 19 is actuatedbya rod 85 mounted in the horizontal portion 2! a of the yoke 2| and this rod is in turn moved longitudinally by one arm of a bell crank 85 pivoted underthe plate 21, the other arm having a downward extension 81 arranged to coact with a pin 8B,'Which pin may be one of the hinge pins for the yoke mem= ber 36. The arrangement provides for the actuation of the roll clutch whenever th'e'roll' is lifted or lowered. When the roll 'is"lifted,'the pin 88 swings toward the crank 86 and moves rod :85 toward the right (Figure 6) swinging lever 19 to move the cam 15 to ball release position. When the roll is lowered, the reverse action of-these parts clutches the roll to the motor drive shaft 65;

In order to prevent overheating of motor 63 it is preferably well spaced from the roll shell and provided with air forcing and directing means for blowing thereover a considerable volume of air. This cooling means consists of a fan 90 at the end of the motor within the spider 6 I, together with a cup member 9! having a central opening 92 and slots 93 for the passage of the arms of spider 6| which latter serve not only as motor supporting means, but as means for directing air from the fan along the walls of the motor.

The cup 9l'serves to turn longitudinally of the motor all of the air projected radially by the fan. The air is admitted and allowed to exit through suitable holes 95 in the ends 12 of the roll.

' ed to a. suitable connecting block |1a some distance from the openingl'ib through which the conductor enters the base. From this block, connections may be made to the shoe l3 and motor 63. The distance between block Ha and opening I'lb permits the thrusting of the conductor into the hollow base as shown.

In Figures 11 to 13 there is shown a feature of construction permitting the easy adjustment of the ironing shoe l3 to provide proper alignment of the shoe l3 and roll 20. In these figures, the frame |0-'H--l2 is shown as made of two side members Ila and H b fixed by welding or otherwise to a filler or spacer plate Ilc, these three parts forming the sides and inner surface of the U-shaped frame.

At the upper ends of the members Ha and Nb adjacent the ironing shoe l3, are provided the outwardly extending ears HI, perforated for the passage of bolts H2. At the back face of shoe l3, the heating element (not shown) is enclosed in a'tray H3 fixed to the shoe and supported upon the upper end of the pedestal l I formed with the ears Ill.

At the central portion of tray H3 are formed two curved surfaces l I 4 so formed as to be portions of a sphere. while the ears III are correspondingly curved and spaced.

When the bolts H2 curved The partlZllis a shield over the tray I I3.

This application .is. adivision of application Serial No. 410,709, filed September 13, 1941 now abandoned. I V

Now having described the invention and the preferred embodiment thereof, itis to be under-- stood that said invention is to be limited, not by 66 the specific details herein set forth, but only by the scope of the claim which follows:

I claim:

In an ironing machine having an ironin shoe and a rotatable roll, one of which elements is f xed in position and the other of which is movable toward and from the fixed element, means for mounting the fixed element comprising a support member having at its upper end a spherical cup formation, means on said fixed element adapted mate with said cup formation, said mating portions being provided with slotted openings, and bolts loosely fitted in said openings and adapted to fix said portions in adjusted position.
