This invention relates tomeans for sup-* porting shoes 'in machines for-operating thereon, and in one aspect has especially in view the provision .of improved shoe-supporting meansin machines for lasting the heel ends of shoes, this application being a division" of a copending application Serial No; 355,566, filed on April 16, 1929, upon ited in its-applicability to machines of that particular character. p

In machines for lasting the wipers apply substantially equal pressures object of the present invention is to provide .a r. in such a rnachine im roved shoe-supporting means so'constructe as readily to obtain that result in the operation of the wipers; For the purpose in view the construction herein shown comprises a shoe-supporting member provided with the usual last pin or spindle and mounted for movement about an axis extending lengthwiseof the shoe substantially in the location of the heel seat, so that the shoe maybe tipped laterally with out any substantial lateral displacement of portions of the sides thereof that are near the heel seat and are engaged by the usual heel-clamping band. This permits each'shoe to be tipped as required to present its heel seat in substantially parallel relation 'to the plane of the wipers, notwithstandingsuch variations as there may be in the locations of the spindle holes in difierentlasts, without substantially altering the position of the shoe laterally in relation to the wipers and without undesirably affecting the relationof the shoe to the heel band. As illustrated,'the

mountedand controlled as to permit it to be moved as described by the action of the lastthereon ,as the latter is tip edpby the olper-e ine lasts, however,. the spindleholes are :not ah ator in 1 presenting the wor toythe mac or is furthertipped by the pressure of the I wipers on the heel seat; The, construction shown further compr ses novel means where.

by the supporting member is normally mainthe heel ends of: shoes bymeans of wipers it is desirablethattained 'yieldingly in a substantially central position'from which it may be moved in onelasting machine disclosed in the above-men;

tioned Letters Patent, and

Fig. 2 isa section on the li en-Her the above-mentioned Letters Patent,,the ma- ChIIiG comprises Wifpers 10 for wiping 'the marginal portion the heel end of the upper inwardly over a sole or insole on a last at the opposite sides of I ously, a heel band 12 which embraces and clamps the upper about the heel end of the last byengaging its end'and side faces in locations near the heel seat, and a jack post 14 mounted for swinging movement in a direction lengthwise of the shoe from'a workreceiving position into position to present the last and shoe Within the heel band 12, the Jack post carrying a spindle 16 arranged to pro ect into the of the last. After suchmovement of the jack post the heel band is operated automatically to clampthe shoe and the wipers are then operated to wipe the margin of the upper'inwardly over the sole or insole and to press it firmly down prior to the drivingofupperfastening tacks.

It is desirable that in the heel-seat lasting operation thewipers 10 shall wipe the margin of the upper inwardly and press it down with substantially equal pressures at the opposite sides of the heel seat. In different ways arranged in the same angular, relation to the bottom faces ofrthe heel ends of the,

PATENT O CE the heel seat simultanespindle hole inthe heel end relation to the plane of the wipers, notwithstanding such variations in the construction of different lasts, the upper end of the jack post 14, in the construction herein shown, is provided with a slot arranged to extend laterally of the shoe, and the portions of the post at the opposite sides of the slot have upper faces 18 curved about an axis extending lengthwise of the shoe substantially in the location indicated at the point 00 to provide a guideway. Mounted in this slot is the lower portion of a shoe-supporting member or block 2Q which carries the spindle 16, this block having shoulders curved similarly to the faces 18 and seated thereon. The block' 20 and the spindle 16 are thus movable laterally of the shoe about an axis extending lengthwise of the shoe and located, as herein illustrated, substantially at the heel-seat face of the shoe midway between its opposite sides, so that the shoe may be tipped to position the opposite sides of the heel seat in the same relation to the plane of the wipers wlthout any substantial lateral bodily displacement of portions of the sides of the shoe that are located near the heel seat.

The block 20 and the spindle 16 are normally centralized by means including a coil spring 22 which is mounted in a recess in the lower end of the block with its axis extending widthwise of the shoe and is held under compression betweentwo disks 24 slidingly movable in the recess in which the spring is mounted. The right-hand disk 24 is normally seated against a shoulder on the block, and the other disk against a lug 26 which is detachably fastened tothe'block. The block 20 is provided with a transverse slot extending across it laterally of the shoe below the spring 22, and projecting upwardly through this slot and into the recess in the block are lugs 28 which are fastened to the post 1 1 and are normally in engagement respectively with the outer faces of the two disks 24. It will thus be evident that while the block 20 is normally centralized by the spring 22, the disks 24; and the lugs 28, it may be moved in either direction along the curved guideway 18 against the resistance of the spring which is then compressed by the action of one or the other of the lugs 28, as illustrated in Fig. 1. The operator may effect such'move ment of the block and the spindle 16 by tipping the last in one direction or the other as he presents the shoe to the machine, in order to position the heel seat'inwhat appears to him to be the proper plane for the action of the Wipers. If the shoe, however, as thus presented is not exactly in position for the wipers to apply equal pressures at the opposite sides of the heel seat, it may be further tipped in the lasting operation by the pressure of one or the other of the wipers thereon. In order to limit the extent of movement of'the block 20 there is 1 further prosomewhat, as in the operation of the machine on shoes of different sizes. Such variation, however, is not enough to result in any substantial lateral displacement of the portions of the sides of'a shoe near the heel seat by the small amount of tipping movement necessary to secure equalization of pressure on the heel seat, and references in the claims to the axis as located substantially at the heel seat are intended to comprehend such small variations as may result, for example, from differences in size.

In the appended claims the term sole is used as a generic term to define that partover which the margin of the upper is wiped in the lasting operation, regardless of the type of shoe operated upon, and the term heel seat also is used to designate generally that face of the heel end of the sole over which the upper is wiped.

Having described the invention, what I claim as new and desire to secure by Letters Patent of the United. States is:

1. In a machine having wipers for wiping the margin of an upper into lasted position about the heel end of a shoe 011 a lastat the opposite sides of the heel seat; simultaneously, a. shoe support comprising a member mounted for movement about an axis extending lengthwise of the shoe substantially in lateral'displacement of portions of the shoe near the heel seat, said member being so controlled as to permit it to be moved about its axis in response to pressure of the wipers on the shoe.
