Application filed June 8, 1914.I Serial No. 843,72.

T all whom t may concern Be it known that I, ROBERT R. O L1N, a citizen of the United States, reslding at Akromin'the county of Summit'and State-.

' fication.

This invention relates to means'for automatically locating on the pins of a rubberj heel mold the washers which are embedded in the heel to act as abutments for the heads of the nailsor screws used to attach the heel to the boot or shoe.

The invention consists in the devices hereinafter described and claimed.

l'O the accompanying drawings, Figure 1 represents a top plan view of a portion of a mold-Washering device embodying my im provements. Figs. 2 vand 3 represent crosssectional views thereof on the line 2-'2 of Fig. l', showing the slide in its washer-rf ceiving and washer-discharging positions respectively. Fig. t represents an enlarged view of the upper end .of one of the mold ins. P In the drawings, 10 represents the bottom plate and 11 the top plate of 4a heel mold of the usual form, the top plate being the saine thickness as the heel and having cavities or openings 12 shaped to give the heel its proper outline, and the bottom plate 10 having upstanding pins 13 which form holes in the heel between the bottom face of the latter and the embedded washers, said pins being formed at their upper ends with shouln ders 14 on which the Washers rest during the molding operation, and projections 15 'to en.V ter the apertures in the washers and center the latter on the pins. These projections i prefer to make of conical or tapered form as represented in Fig'. 4 tofacilitate the drop- Y pinl of the Washers Aproperly upon the pins.

and of suicient size to permit the passage e embodiment of my invention herein shown consists essentially of a fixed bottom plate 16 adapted to be'positioned over the heel mold and formedv With washerdischarging apertures 17 located above the pins 18 of the Washers, a fixed' top plate 18 formed with Washer-receiving apertures 19 out of line with the'apertures 17 in the lowei.` plate,

and alwaslaer-feediug or transferring plate .2G in the term 'oi' a slide presided wr-.h

washer-receiving apertures 21 adaptedV to register alternately with the apertures 19 in the upperiixed plate and the apertures 17in the lower ixed plate, this slide having the Patented Nov. 2, 19115.,

thickness of a single washer. The slide isA provided with a turned-up edge 22 to act as a handle and with stop pins 23, i tdlmit its movement in both directions', and it-is likewise suitably guided to prevent lateral I I 'prefer to make 'the top i displacement. plateV 1S of considerable thickness so that each of its apertures 19 acts as a magazine Washers 25 stacked one on topof the other,

.for the storage of a considerable number of excess of the washers on the plate and removing those that did not fall into the apertures. also prefer te form thebottom plate 16 with extensions 26 projecting down into the mold cavities 12, so that the aper# tures 17 form tubular guides terminating below the top of the mold-pins 13, in order cy the more effectively to guide 'the Washers onto the pins.

n the operation of this device, each-dof 1 the apertures 19 in the magazine-plate 18 is loaded with. a stack of washers, and' thev automatic Washer-locating device compris.'-

ingy theplates 18, 19, and the slide Gis-v' placed in position over the heel mold com# prising Athe plates 10, 11., as represented in'l Fig. 2. The slidey being drawn. to the lett- 1 ward limit of its movement, the lowerniost washer in. each stack will drop into anl aparv ture 21 in the slide. Slide 20 is then shiftedA to the rightdaand. limit of its movement soas to 'bring its apertures 2l out of line with' the top plate apertures 19 and into line'with the bottom plate apertures 17, the washers l954 in the `apertures 21 beingy thereby carieoln 'I' into position over the mold pins and dropped by gravity onto the shoulders of said pins as represented in Fig. 3, the projections 15 enteringthe apertures in the washers-.Land

When the slide apertures are alined with the The Washer-placing device is thereuponireW wav by placingin each cavity ltlia ref i serving torenter the latteron the pins. i

quired amount of rubber compound and squeezing it down into the cavity with a suitable press-member or die.

lVhile it is possible to load the Washers onto the mold pins Without the presence of the top plate 11 of the niold, l prefer to leave said top plate in position as shown, in order to avoid the accidental disturbance of the Washers by the subsequent assembling of this top plate With the bottoni mold -plate.

It is to be understood that the invention is not confined to the exact details herein shown.

I claim:

l. A heel-Inold-Washering device compris` ing a plate adapted to be placed above the cavity in a heel rnold and formed With apertures adapted to be alined with the mold pins, and a reciprocating Washer trans ferring slide having Washer-receiving apertures movable into and out of register with the apertures in said plate.

2, A heel-Inold-wasl'iering device compris ing a plate formed with usher-receiving apertures, a second plate formed with washer-discharging apertures, and an intermediate slide formed with washer-trans ferring apertures movable reciprocally into and out of register with the apertures in the aforesaid plates.

3. A heel-inold-wasliering device comprisingl a Washerreceiving magazine plate formed With apertures adapted to hold stacks ofwashers, a Washerdischarging plate formed with apertures' out of line iv those in the ivasl'ier-i'eceiving plate, an( intermediate vslide having apertures ada te register alternately with those in the spective plates, and solidv portions adapted to sustain the stacks when the slide apen c tures are alinecl with the apertures in the washer-(fiischarging plate.

4f. A lieelauoldwasiiering device cori" ing a ivaeher-discharging platel havingD extension on its lower side formed v.' tubular apertures `lfor embracing the meld pins and guiding the Washers the1eonto,and a washerfeeding slide having apertures movable into and out or line with those said plate. i

5. The combination with a heel mold coniprising a top plate formed with mold cavities, and a bottom plate provided with washsir-supporting pins projecting into saiil v cavities, of an automatic ivashering device GC comprising a fixed plate supported ontlie top plate of the niold and formed with iv:relier-discharging apertures in line with the mold-pins, and a slide on said fixed plate :formed with apertures movable into and out ot' line with those in said fixed plate.

ln testimony whereof i have hereunto set my hand in the Yin'esence of two subscribing uitnesses, this iltli day of June, 1914.
