ALVA J'. FISHER, OF EVANSTON, ILLINOIS, ASSIGNOR TO HURLEY MACHINE COMPANY,

IRONING-MACI'IINE.

Specification of Letters Patent.

To all whom it may concern Be it known that I, ALVA J. FISHER, a citizen of the United States, residing at Evanston, Cook county, Illinois, have invented certain new and useful Improvements'in Ironing-Machines, of which the following is a specification.

My invention relates to ironing machines of that type in which a heated shoe cooperates with a padded roll in the ironing operation. One of the principal objects of my invention is to provide a novel and efficient driving connection for the padded roll whereby the roll may be permitted to rotate freely in the reverse direction when it is desired to remove the sheeting and' the padding. In this regard it will be understood that several thicknesses or plies of padding is first rolled upon the roll and then several thicknesses or plies of sheeting, and also that this roll is driven at very slow speed by means of reduction gearing. Consequently were the ordinary driving connection employed the rotating of the roll in a reverse direction for the removal of the sheeting and padding would be a very long and tedious job which is entirely avoided by the use of my driving connection which is in immediate cooperation. with the padded roll whereby the roll may be rotated at any speed in a reverse direction independently of the reduction gearing.

In the drawing Figure 1 is a side elevation of my machine; Fig. 2 an elevation of the. right hand end of the machine; Fig. 3 an elevation of the same end of the machine but showing the gear covering open; Fig. 4 a sectional plan on the line 4-4 of Fig. 3; Fig. 5 av central longitudinal section of the padded roll made on a larger scale; Fig. 6 an elevation of the left-hand end of such roll; Fig. 7 an elevation of the other end thereof; and Fig. 8 a section on the line 88 of Fig. 6 but on a larger scale.

Referrin to the embodiment of my invention as herein shown the machine is provided with a supporting frame work composed of the end frames 1 and the tie-rods 2 connected therewith. Upon the tops of these end frames are supported the bearing brackets 3 for the horizontal driving shaft 4: of the padded roll 5. In so far as my present invention is concerned the driving mechanism for rotating the shaft 4 may be of any desired character. In the present in- ]Patented May 6, 191?.

Application filed October 15, 1914. Serial No. 866,773.

stance the prime mover is an electric motor 6 supported by one of the end frames and adapted to communicate its power through the following described driving connections including reduction gearing. As shown the armature shaft is provided with a driving pulley 7 which, through the medium of the belt 8 transmits its power to the large pulley 9 which is loosely mounted upon one end of the shaft 4. Suitable reduction gearing is interposed between this large pulley 9 and the shaft 4 as indicated generally at 10. I prefer to. employ and I have illustrated. the character of reduction gearing which is made the subject-matter of my application filed March 19. 1914, Serial Number 825,792. For purposes of the present invention it will therefore suflice to say that the rapid motion of the motor is reduced by the reduction gearing so that a very slow movement is given the shaft 4. The large pulley and the reduction gearing are inclosed and protected by a suitable casing or housing 11 having a door 12 for easy access to the mechanism.

The padded roll is provided at its ends and also intermediate its length with flanged disks or spiders 13 which are mounted to rotate freely upon the shaft 4. Upon this shaft and at points adjacent the spiders are secured by suitable means. as by the set screws 14, a series of driving collars 15 which have circular recesses 15 to receive the projecting hub portions 13 of the spiders, Fig. 5. A rod 16 extends through all of the spiders longitudinally of the roll and parallel with the shaft 4 and to this rod is secured a series of dogs 17 which are located on the rod at a point adjacent one side of the spiders. This rod is adapted to be rocked and the dogs are in such position that they will be in the path of movement of projections 18 on the'driving collars 15, as shown in Figs. 6 and. 7. When the'dogs occupy the positions shown in said figures the padded roll will .be positively driven by the shaft 4: but when the rod 16 is oscillated to swing the dogs out of engagement with the pro ections 18 as shown by dotted lines in Fig. 6 the operating connection between the shaft 4 and the padded roll will be broken so that the roll may be reversed by hand and run at any speed in the act of removing the padding and the sheeting formin the ironing surfaces of the roll. In or er that the, rod 16 shall be held in its .spider, Fig. 6.

different positions I provide the left hand end dog 17 (Figs. 5 and 6) with a pin 19 passing therethrough and through a. spring chamber therein for a spring 20 which tends to hold the pin projected into a hole 21 in the adjacent end spider as seen in Fig. 8. By drawing the pin 19 outwardly by hand the rod 16 may be rocked and when the dogs are swung to an inoperative position the pin will engage into another hole 22 in such end As shown in Fig. 5 the padded roll 5 comprises a. cylindrical shell preferably of sheet metal in which said spiders are pressed so as to be held therein and on which is wound the padding and sheeting shown in plies or thicknesses thereon and both indicated by the reference characters 23.

I claim:

1.; In an ironing machine including a cylindrical shell, a driving shaft on which said shell is loosely mounted, a series of engaging members carried by said shaft, a corresponding series of engaging members carried by said shell and arranged to cooperate with said first-mentioned engaging members, and means common to all the members of one series of engaging members for establishing and disestablishing cooperative relationhsip with the members of the other series.

2. In an ironing machine including a cylindrical shell, a driving shaft on which said shell is loosely mounted, a series of engaging members carried by said shaft, a corresponding series of engaging members carried by said shell and arranged to be shifted into and out of cooperative relation with said first-mentioned engaging members, and means carried by said shell for shifting said second-mentioned engaging members into and out of cooperative relationship with said first-mentioned engaging members.

3. In an ironing machine, including a roll, the roll being a cylindrical shell and having a series of circular members secured therein, a driving shaft which passes through said members and on which they are loosely mounted, driving collars secured to the shaft and dogs adapted to be engaged by and to thereby drive such members and roll, said dogs being manually movable from their said engagement.

4. In an ironing machine, including a roll, the roll being a cylindrical shell and having a series of circular members secured therein, a driving shaft which passes through said members and on which they are loosely mounted, driving collars secured to the shaft, a rock shaft parallel to the driving shaft and extending through said members, and dogs secured to the rock shaft in proximity to the driving collars and adapted to normally form a driving connection between the collars and members.

In an ironing machine, including a roll, the roll being a cylindrical shell and having a series of circular members secured therein, a driving shaft which passes through said members and on which they are loosely mounted, driving collars secured to the shaft, a rock shaft parallel to the driving shaft and extending through said members, dogs secured to the rock shaft in proximity to the driving collars and adapted to normally form a driving connection between the collars and members, and means cotiperating with the rock shaft for holding it in different positions.

6. In an ironing machine, including a roll, the roll being a cylindrical shell and having a series of circular members secured therein, a driving shaft which passes through said members and on which they are loosely mounted.- driving collars secured to the shaft, a rock shaft parallel to the driving shaft and extending through said members, dogs secured to the rock shaft in proximity to the driving collars and adapted to normally form a driving connection positions.
