WASHER-PLACING APPARATUS.

Application fil To all whom it may concern:

Be it known that 1, CHARLES GARDNER,

the United States, and resident o't Summit and State citizen of Akron, in the county of of Ohio, have invented certain ful Improvements in l paratus, of which the cation.

The invention aims to provide a simple and economical form of apparatus by wh ch the washers may be expeditiously handled and accurately placed on the said invention comprises of construction bination of parts pins, and the the novel features and arrangement and comhereinaiter desorlbed and V particularly defined by the claims appended hereto.

An embodiment oi my invei trated in the accompanying \vh1ch:

Fig. 3 is a like Fig. 1 applied to a heel mold is a similar view with the washerapplied view showing the partsot and with the washers projected onto the mold pins.

Fig. 4 is a detail view. Referring by reference char acters to this drawing, the numeral 1 designates the lower section of the heel mold having the customary upstanding washer-holding pins 1 to receive and hold the washers 2, which,

as shown, are of somewhat dished form, or

Plate 5 is held slidably superposed on plate a in det suitable means suc elongat ed openings l ermined relation thereto by h as dowels 5 engaging in the plate 4, the re.

In the manufacture of curved heel lifts, such as shown in the I. T'. S. heel, the upper ends of the pins are not in the same plane, as shown in Fig. 8, and hence the openings 4 cannot be closely juxtaposed to all the pins, and a space is left above some of the pins which permits the washer to tip as it is released by the sliding action and hence fail sometimes to engage the mold pin. To avoid this objection, I provide means for holding the washers in place in the washer seats until the latter are fully uncovered and then forcibly ejecting them, whereby tipping of the washers is prevented.

Such means preferably takes the form of a carrying member 6 having spring pressed plungers 4' provided with concave lower ends 7 and mold pin receiving recesses 7 These plungers are grouped to correspond to the openings 5 and means are provided by which member 6 may be properly held relative to plate 5, such means conveniently taking the form of shouldered dowels 8 having their reduced upper ends 8 engaging openings 6 in member 6.

The plungers 7 are slidably guided in guides or openings 6 of member 6 and held against dislodgment therefrom by cotter pins 7 and they are provided with annular ribs or shoulders 7 between which and the lower surface of plate 6 compression springs 9 are confined. In using this ejecting means, plate 6 is superposed over plate and aligned therewith by dowels 8 while the washers are held in the seats, plate 6 being pressed towards plate 5 to compress the springs, and held in such position by means of catches 1O engaging detents or keepers 11 carried by upturned flanges A of plate 5. If now the assembly is applied to a heel mold and plate l is moved to align the openings 46 and 5 the pressure of the plungers will hold the washers against the surface of plate 4 by reason of their annular engagement, until the openings are perfectly aligned, and thereafter the washers will be projected upon the pins without danger of tipping or deflection, as shown in Fig. 3,

it being understood that the plungers act more rapidly than the force of gravity.

Having thus described my invention, what I claim is 1. A washer-placing device comprising a pair of plate-like members slidably juxtaposed and having each a group of washerreceiving openings adapted to be aligned by a relative sliding move ient of the members, means for properly registering such members with a heel mold, and means for forcibly expelling the washers when the openings in such members are brought into align ment.

2. A washer-placing device comprising a pair of plate-like members slidably juxtaposed and having each a group of washerreceiving openings adapted to be aligned by a relative sliding movement of the members, and means for properly registering such members with a heel mold, said means com prising aligning do/wel openings in said members, the openings in the lower member being elongated.

3, A washer-placing device comprising a pair of plate-like members slidably juxtaposed and having each a group of washerreceiving openings adapted to be aligned by a relative sliding movement of the members, a carrier member adapted to be removably secured over the upper of said members, and a group of spring plungers sup ported by said carrier member. tioned to correspond to the openings in said upper member.

4-. A washerplacing device comprising a pair of plate-like members slidably juxtaposed and having each a group of washerreceiving openings adapted to be aligned by a relative sliding movement of the members, a carrier member adapted to be removably secured over the upper of said members, and agroup of spring plunge-rs supported by said carrier member, and positioned to correspond to the openings in said upper member, said plungers having annular washercontact portions at their lower ends.

In testimony whereof, I afiiX my signature.

CHARLES GARDNER.
