e Machinery Corporation, Boston, Mass, a corporation ofDelaware Application April 29, 1943, Serial No. 485,007 '1' Claims. (01.12-126) signor to Compo Sho This invention relates to means for supporting shoes, whether carried on lasts or forms, for presentation to mechanism for operating on the shoes. While not restricted to supporting the shoe for any particular operation, the support for the present invention has been designed more particularly to suit the requirements of mechanism for pressing the contour portions of shoes into smooth contours with the adjacent surfaces of the shoe heels, and more particularly when the heels are of the wood heel type, where the heel seat margins of the heel are seated directly against the shoe upper. Such a mechanism is disclosed, for example, in my Patent No. 2,357,- 596 for Heel seat conforming machine, granted September 5, 1944. For such service it is necessary to adjust the height of the shoe, and the level of the heel seat portion, both longitudinally and laterally. This is complicated by varying positions and angularities of last pin holes in lasts or forms which may be off center or inclined from proper positions, or both, difierent heights of lastsor forms, and irregularities of positioning of shoes on lasts or forms.

s It is also highly desirable to provide for supporting both rightand left shoeson the same support, and for this purpose lateral adjustment of the jack pin and its holder as a unit is provided.

As applied to mechanisms for pressing the counter portion of a shoe in accordance with my patent hereinbefore noted, the pressing apparatus serves to automatically position the shoe properly laterally, both bodily and angularly, when proper adjustment for height and longitudinal angularity has been effected by the operatoi'.

For a more complete understanding of this invention, reference may be had to the accompanying drawings, in which Figure 1 is afragmentary vertical sectional view of the support on line I-l of Figure 2.

Figure 2 is a similar sectional view on line 2-2 of Figure 1. v

Figure 5" is a more complete top plaiifyi'ew of the machine than is Figure 4. --Figure 6 is a sectional view on line 6-5 of Figure 5. v 1 I Referring to the drawings, at l is, indicated e mat a base which carries'the shoe supportingmech;

. 2 anism. It is provided with an upright socket 2 within which is slidably mounted a post 3. This post, as shown, is provided with a threaded bore 4 extending upwardly therein into which is engaged the upper threaded portion 5 of a shaft 6 journaled in the lower reduced diameter portion of the socket 2 and provided with a flange I seated on an annular shoulder 8 therein, which holds the shaft in proper position.

Below the base the shaft 6 has keyed thereto a worm wheel H] with which meshes a worm ll carried. by a horizontal shaft l2 journaled in the base and provided at its forward end convenient to the operator with a hand wheel l5 by which it maybe turned, thus to adjust the post 3 vertically. At the upper end of this post, it is provided with an extension projecting toward the operator and toward the toe portion ofv a shoe indicated by broken lines at 2| and carried by the support. This extension Zli'is provided with an upright threaded hole 22 in which is engaged the upper threaded end portion of an abutment 23. The lower portion of this abutment is formed as a rod 24 which extends downwardly through a passage 25 in the base and has fixed to its lower end beneath this base, means such as a knurled knob 26, by which the rod 2d may be turned, thus raising or lowering the abutment 23. On this abutment rests one end portion of a block provided with a wall'portion 31 resting upon the upper rounded and of the abutment 23. This block 30 is provided with an opening 32 therethrough into which the upper end of the post 3 extends, this opening 32' being considerably wider than the upper end of the post 3, as shown best in Figure 1. Through this upper end portion of the post and the side walls 33 of the block extends a pivot pin 34, the ends of which form a tight fit in the walls 33 and the intermediate portion of which is rcckably mounted in a transverse hole 35 in the top of the post. This arrangemerit permits the angular position of the block tobe adjusted about the axis of the pivot pin 34 by adjustment of the abutment 23, and it also permits free lateral sliding of the block lengthwise of the pin 34. This free or unconstrained rectilinear sliding motion is laterally of a shoe carried by the support, as shown in Figure 1 and permits free lateral adjustment of the shoe to provide for right and left shoes and for shoes supported on lasts or forms having varied positions of last pin holes and also for shoes that may be mounted in various positions on either lasts or forms. Quite often after lasting or seeport.

the ends of the block 30. Where a form is em=- ployed it is shaped like at least the rear portion of a last.

This pivotal motion of theyoke nie'iriber fl permits a free limited rocking motion 'of the in 40 laterally of the shoe, this allowing for adjust ment of the level of the heel seat of th'e'shoe to permit the heel seat on each side to be brought. into proper relation to a pair of sidegagesil) inwardly extended from the upper face of the base I. The level of the heel seat lengthwise of the shoe is adjustable by adjustment of the abutment 23, the last pin locating the shoe suinciently near to the axis of the pivot 34so that the shoe tends to tilt forwardly with theblock 30 resting upon the abutme'nts 23, while the shoe as a who'le may be adjusted up and down by turning the handle i 5. Thus the heel seat of a shoe whether right or left, and the-heel seats of shoes mounted on forms or lasts with difierent positions of last pin holes or the heel seats of shoes which may be mounted-in diife'rent positions on either lasts or forms may be brought into proper relation to the means which operates on. the shoes, in an easy and expeditious manner.

In Figures 1 and 4 the shoe support is shown as associated with side andrear counter pressing form blocks 55 which are connected together to form a substantially continuous shoe-engag ing face having a continuous surfacing layer 550 by arcuate keys 56 slidably related thereto. These blocks are arranged to be closed in "about the heel end of a shoe supported onthe last or form, and which is pushed rearwardly' tothe dotted lineposition into engagement therewith, by forward motion or the arms 57, having quah izer levers 58 engaging the forward pairs of blocks 55. This inward motion of the blocks 55, which in definite paths, acts by pressingengagement with one or the other side of the shoe automath cally to correctly position the shoelater'aily lengthwise of the pivot and angularly about the axis of the pivots 45, so that the "side edges of the heel seat come at the proper levels for the desired pressing operation when the height and the lengthwise angular adjustment have been properly made. H

As shown also in my Patent No. 2,357,596, to which reference has already been made,- the central block 55 has a pair of spaced upper and lower projections 68 (Figure 6) through which passes a pivot pin Bl, the lower end of the pivot pin extending into a guide channel 52 in theto'p face of a table 63. mally' pressed forwardly toward the'shoe'support by means of a spring 6 4, the rear end of which is seated in a block 65 securedto'the-table 63. This permits the block 55 to be pressed rearwardly by engagement thereagainst of the heel end of a shoe 2| carried by the shoe sup- Such rearward motion of the central block 55 acts to rock a pair of arms 65 pivoted one above the other on the pivot pin 6| engaging fixed stops 61 and bearing against the block 55 This central bl'ock 55*is' nor next adjacent to the central block 55. This tends to close these adjacent blocks against the shoe upper. The fixed stops 6! also constitute pivots for the arms 5'! between rollers journaled at the rear ends of which is positioned a wedge block 68 against which the rollers of the arms 51 are held by a spring 69. A thrust rod 'lfl extends trom the r ar larger end "of the wedge block 68 and this rod 10 extendst'hrough a slide block 1|. A collar and nut on the rear end of the rod 10 limits the rearward motion of the slide block 71: A coil spring 12 surrounds the rod 10 and reacts between the slide block H and an adjustab collar "on the rod. The forward motion of the sli'd'block H thus applies yielding forward pressure'on the wedge block 68 and closingpressure of the wedge blocks 55 against the side portions of a shoe on the support adjacent to" theshoe heel seat. As the shoe is free for lateral adjustment, this closing of the wedge blocks causes the shoe heelportion to be presented" in the samelateral position whether it be 'of a right or left shoe;

Me'ahs are provided for moving the shoe sn p port forwardly into'inoper'ative or loading positlon i and rea'rwardly' into operative position with the heel portion o'f'the shoe thereon in operative relation tothe: pressure mechanism; and for opening closingthe pressure mechanism in suitablytimedrelation. Ihis'means may comprise *a motor '15g'e'ared to a drivesnait 16 carryingan 'eccentric 11, conneetedthrougha strap la -a mi link 1'9 toabellc ank lever secured to 6. rock sh'a'ft'tl.

Rotation of the shaft 15 is thus caused to open and closethe pressure mechanism'against the shoe. lt i's also connected to move the shoe support forwardiyan'd backwardly in proper timed rela'ti'on to the opening: and closing motions of the pressing mechanism.- For. this purpose, one 85 of the bell lever Bil-has a pivot member 86 perforated for the'sl'idable passage of" a li nk 8'l; connected at its forward end to the shoe support I'w-hioh is slidabiy mounted or themachine The pivot' r'n'ember 8 6 engages-'a-spring abutment 88 between which and nuts 89 on the rear end of the link- 8'! a coil spring 90"is positioned.
