This Crank is actually a casting 50 and shoe is provided, which permits rotation of having an indented cam portion 23 formed inthe roll 10 and intermittent movement of the tegrally therewith. Further, awmanually conironing shoe towards and from the roll by means trolled release handle 24 is either formed inteof various kinds of driving connection. grally with or secured in said casting 23. It w The movement of the ironing shoe 11 towards will be noted also that the cam 23 iscapable 55 sition with respect to the stationary support 13 the spring 18 acting as described to retain cam 23 in abutment with portion 25.

It will be noted that movementkof the support 13 induced by the intermittent rearward and forward movement of the bar 12 will merely cause the shoe to assume the ironing position shown in Fig. 1, or a rearward position somewhat away from the roll. However, irrespective of the movement of the shoe as above described, the release handle still maintains a hxed position, due to the connection between`the cam portions 23 and 25.

It is apparent that when the handle is in its normal and fixed position with respect to support 13, the shoe supporting bracket 15 has moved forwardly and that tension has been created between said support and the member 13. However, should the operator desire to release the ironing shoe 11 from the roll 10 quickly and prior tov any movement of control means, not shown, which would move the support 13 to a rearward position, he merely strikes the releasel lever .24 sharply in a rearward manner. This movement of the release lever obviously disengages the engaging surfaces 23 and 25 and automatically, due I to this movement. as well as movement of the coil spring, the shoe is moved sharply away from the ironing roll.

Quick release mechanism of various types, although different from that herein shown, is used to release the ironing shoe suddenly in case of ang accident of any character. However, in the present instance, applicant has so fashioned his quick release mechanism as to accomplish also another object. Upon viewing Flg. 2, it will be found that the operator has not only released the cam connection, which in turn quickly releases the ironing shoe, but that he has also moved the manual release lever such distance rearwardly as to move the ironing shoe to a horizontal position, such movement being flnally induced by a portion 26 of the cam abutting and supporting the under side of the shoe 11. 'I'he ironing shoe, when held in this position, is now sufficiently removed and so positioned in a horizontal manner, as to be capable of use for a steaming operation.

It is thought apparent that applicant has provided not only a simple quick release mechanism, but also one capable of further operation to enable it to be used also for the purpose of moving the ironing shoe to a steaming position, without touching the shoe with the hand. i

Further, with respect to the operation of applicant's device, it is apparent that in order that the ironing shoe may again assume an operative position adJacent the ironing roll, the operator must flrstmove the release handl'e 24 to a.`` forward position, wherein the cam surfaces 23 and 25 will again be engaged. Thus, the ironing shoe is again held in a fixed position with respect to the support 13 and further, said shoe has assumed such position that forward movement of the support 13 will press the ironing shoe against the roll and vice versa.

What I claim is:

1. In a device of the class described, in combination, an ironing roli, an ironing shoe, a lever member having a predetermined movement towards and from the ironing roll, an ironing shoe support movable relative to said lever and roll, a connection between the lever and the ironing sh, tensioning means connecting the lever and support adapted to urge the support toward the lever and away from the roll, a manually operated cam adapted to positively move the support and shoe relative to the lever in opposition to the tensioning means, the tensioning means adapted to co-operate with the cam in such a manner that when the cam is moved in o ne direction the shoe is positively moved toward the roll, whereas when the cam is moved in the opposite direction the tensioning meansoperates to move the shoe away from the roll.

2. A device of the class described having in combination an ironing mil, an ironing shoe, a shaft having predetermined rotational movement, al lever member afiixed thereto, said rotational movement of the shaft being such as to bring about movement of the lever member toward and from the ironing roll, an ironing shoe .support pivotally supported upon said shaft to move relative to the lever and roll, said ironing shoe being pivotally supported thereon, tensioning means connecting the lever and support to urge the support toward the lever and away from the roll, a cam member pivotally mounted upon 'the support member, manual means for Operating the cam upon its pivot, the cam being co-operative with a portion of the lever member and of such conformity that when the cam is moved in one direction the support member and shoe are moved away from the lever and toward the roll in opposition to said tensioning means 'and when moved in the opposite direction the tensioning means is rendered effective to move the shoe away from 'the roll, a portion of the cam being co-operative with the shoe whereby when the last mentioned movement of the cam is continued the said portion engages the shoe to bring about pivotal movement thereof 'to move the shoe lto horizontal position.
