UNITED STATES PATENT OFFICE.

ALVA J'. FISHER, OF EVANSTON, ILLINOIS, ASSIGN OR TO HURLEY MACH IRON IN G-1VIACIIINE To all whom t may concern.' l a Be it known that I, ALVA` J. FISHER, a citizen of the United States, residing at Evanston, in thecounty of Cook and State of 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, and pertains more particularly to the construction and operation of the shoe. The generalobj ect of my invention is to providesuch a construction of pivoted shoe so that the same can be swung away from the roll in the regular or normal operation of the machine, and can also bev moved bodily away from the roll to an ab- `normal position whenever it is desired to clean or dress the inner or operatingsurface of the shoe. To this end I provide vnovel operating connections for normally holding the shoe against the roll with a yielding pressure and for supporting it when swung away from the roll, and I pro` vide in addition a construction whereby the entire pivotal mounting of the shoe can be moved bodily away from the roll so as to remove the shoe a considerable distance from the roll for the special purpose eX- plained.

In the drawings Figure l is a side elevation vof my machine; Fig. 2 an end view thereof; Fig. 3 a cross-section on the line 3--3 of .'F ig. l, but on a larger scale and showing in full lines the shoe in coperative position with respect to the roll and inndot- .ted lines in its ordinary swng-away p osition; F 4 a view similar toF ig. 3 excepting that the, shoe has been moved away from the roll to its abnormal position; Fig. 5 a sectional elevation of the yielding connection acting on the shoe to'hold it in position against the roll; and Fig. 6 a plan view of the lefthand end of this connection as shown in Fig. 5.

Inasmuch as my invention pertains only to the shoe of the ironing machine only those parts of such machine as are directly concerned need be explained, The machine frame 1 has at its oppositeends brackets or end frames 2 in which the roll 3 is jour naled. The shoe 4l is provided as usual with the heating chamber 4a and with the curved ironing face 4h which is adapted to press.

pivots being received within oblique slots 2a in the end frames of the machine, said slotssloping upwardly away -from the vertical plane through the roll so that the rear faces of the slots, coacting with the pivots for the shoe, resist effort to displace thel shoe bodily in a rearward direction, and define the normal position of the shoes pivotal aXis.

The yielding operating connections which coperate with the shoe are arranged in two sets one at each end of the shoe. As the sets are similar in construction-a description of one will applyto both. At the front side of the machine 'a rock shaft 7 is supported in the end frames 2 of the machine and' provided with an operating handle S. At each end .this rock shaft has secured to it a pair of arms 9 between whose outer ends and the shoe is interposed the yielding operating connection.7 As shown in detail in Fig. 5 this yielding connection consists of two heads l0 and 1l, adapted to telescope on each other and kept apart by means of the coiled spring 12. The outermost head l0 is pivotally mounted upon the outer end of the arms 9 and is provided with a central bore l0El adapted toreceive the rod or stem 13, which is secured to the otherhead ll. The spring 12 bears at one end against the head 1l and at the other end against the adjusting nut 14, screwing onto the head 10, whereby the tension of the spring may be adjusted. The outer end lla' of the head 1 1 is ball-shaped and is adapted to be received by a socket 5a in the shoe. When the rock shaft 7 is rocked in anti-clockwise direction, Fig. 3, and to the dotted line position shown in that figure, the pressure of the operating connections against the shoe will be relieved and such shoe willdrop away slightly from the roll by virtue of its gravity, the pivotal movement being on the pivots 6 as the axis of movement, it being understood that during this movement these pivots remain in fixed position at the lowermost ends of the slots 2a. When the rock shaft is restored to normal position the pivotal point 9 takes a. position below the line between the center of the rock shaft 7 and the point of contact of the ball-shaped end of the head 11, so that the operating connections bearing against the shoe are locked in position.

'Ihe above described construction pro vides for ordinary operating movements of the shoe, but in order that the shoe maybe bodily swung away from the roll at a considerable distance, I provide means for bodily moving the pivot 6 upwardly in the slots 2a upon an abnormal movement of the rock shaft 7. These means consist of the links l5, the outer ends of which are piv otally connected to the pivot 9a and the inner ends of which are slotted at 15a to receive the pivot 6. In the normal operation of the connections `described these links have no function inasmuch as .by virtue of the slots 15a the links merely slide upon the pivots, but upon an abnormal movement of the rock shaft the ends of the slots will engage the pivots 6 and move them upwardly in Vthe oblique slots 2, so that the shoe which by the preliminary or normal movement of the operating connections has been swung away from the roll on the pivot 6 will be bodily moved awa from the roll to the position shown in big. 4, which gives the proper amount of access to the ironing face of the shoe for the purpose of cleaning and dressing the same.

I claim:

1. In an ironing machine, the combinat1on of a roll, a coactingV shoe, mountings for Said shoe permitting the shoe to turn into and out of contact with the roll in normal operation about a pivotal axis that is beyond the roll-contacting surface of the shoe and permitting the rearward displacement of said shoe bodily from said normal-operation-position, and means for controlling the rocking of the shoe pivotally and for bodily displacing it as aforesaid.

2. In an ironing machine, the combination of ,a roll, a shoe cooperating therewith, bodily displaceable pivots for said shoe beyond the roll-contacting surface thereof, whereon said shoen may swing into and out y of contact with the roll in normal operation, and operating means connected and movable to first occasion' a. rofcking of the shoe on its pivots out of roll-contacting position and thereafter bodily to displace its pivots and further separate' the roll an shoe.
