Application led August 4, 1921. Serial No. 489,794.

T0 all 'whom it may concern.'

Be it known thatl, VALDMLAR D. KMENTT, a citizen otl the United Stat-es, residin at Akron, in the county of Summit and btate of Ohio, have invented a certain new and useful Heel- Mold-fashering Device, ot which the following is a specification.

This invention relates tor means for accurately positioning a large number of small artic-lesran example being the placing ot washers upon heel mold pins preparatory to the molding and vulcanizing of rubber heels wherein the washers are imbedded to serve as abutments tor the" heads of the nails by which the heel is secured to the shoe.

Machines heretofore devised for this purpose have not proved entirely satisfactory. and it is the object of my invention to overcome their defects by the provision of an appliance which is both rapid and accurate in its operation and is adapted to be made in a compact, readily portable form, my invention in some aspects heilig au improve ment upon the type of device shown in patent to Olin. No. 1,159,077 of Nov. 2. 1915.

Ot the accompanying drawings:

Fig. 1 is a plan view ota preferred embodiment of my invention.

Fig. 2 is a vertical section on line 2 2 of Fig. 1, showing the parts at one stage ot' the operation.

Fig. 3 is a similar view of the device in position upon a mold. showing another stage ot the operation.

Fig. 4 is a horizontal section on line 4 4 showing an intermediate stage oie the operation.

Referring to the drawings, 10 is a cylindrical casing. provided with a handle 11 and with a bottom or base-member 12 formed with a guide-boss 13 adapted to tit into the heel cavity 1% of a mold 15 to position the device. said casing and base-member constituting a frame structure. Said base member 12 is formed with holes 16, 16 ot' suli cient size t'reely to permit the passage and lateral play ot' guide tubes 1T. 1T suspended from parts ot' the device presently to be described, said guide tubes being internally beveled at their bottoms to tit the conical bases ot' the mold-pins 18. 18 (Fig. l) and thus adapted to be individually guided into position upon said pins. and preferably weighted at their lower ends. as is indicated by their thickened walls. to facilitate their settling` in place upon the pins. 19 is a washer in molding position upon one of the pins.

'ithin the casing l() is fitted a cylindrical slide 20. which may be formed of tubing, the upper portion of said slide being vertlcally slotted at 20ato embrace the arms of a spider 21 fixed in the top ot the casing 10.

the slide Q0. just above the guide tubes 1T.

is a relatively-thick plate 25 formed with downwardly and inwardly inclined washerguiding apertures 26. 26 whose upper ends are in two circular series and whose lower ends are located directly over the mouths of the guide-tubes 1T, which latter are tiared. as shown, to facilitate the entrance ot the washers. Secured within the slide. 20,/"above the plate Q5. and spaced-therefrom to accommodate a thin oscillatory transfer plate or slide 2T. a magazine bottom-plate 2S toi-med with two circular series of apertures Q9. 29. 3U. 30. circumterentially aligned with and otlset t'rom the guide apertures QG in the plate. 25. cach aperture being adapted to hold a stack of washers as indicated at 3l. Fig. 2. The magazine bottom-plate 28 is also toi-med upon its upper t'ace with an annular tiange or ridge 32. separating the two circular series of apertures Q9. 30, for directing the washers into said apertures. and on its bottom tace is termed with shallow. annular channels 33. $33 connecting the respective apertures in each series and permitting.

the transt'cr ot' the washers from the magazine apertures 29. Ik() to the dischargeapertures lo by the oscillatorv transfer plate 2T.

.which latter preferably is ot less thickness than the thinnest washers used. in order to avoid engaging more than one washer at a time and choking the device. the channels being ot such depth as not to permit the passage of more than one washer ot any thickness used.

The transfer plate QT is 'formed with apertures 2T. 2i. slightly larger in diameter than the washers. and may be moved to register said apertures with the magazine apertures 29, or with the guide apertures 26. Said transfer plate is centrally secured to a hollow shaft or sleeve 34 rotatably stepped in a countcr-bore at the center of the plate 25. This sleeve is formed near its upper end with helical cam grooves 35, enacting with cam rollers 36, 36 on the spider 21, in which said sleeve is also journaled, to turn the sleeve and the transfer plate 27 as the slide 2O is raised and lowered with respect lowermost washer of each stack.

to the casing 10. Also secured to the sleeve 34 is an oscillatory, annular, webbed agitator or paddle S7, rotatably fitting the interior of the slide 2O and marginally formed with an inwardly sloping base flange 38 for directing the washers into the magazine apertures 29, 30.

Extending through the sleeve 3l and the plates 25. 22, is a side-bolt 39 having secured upon its upper end a hand knob 40 adapted to abut against a nut al,v on the bolt to lift the latter' and also adapted to bear upon the top of the sleeve 3l and force the latter, the slide 20, and the parts carried thereby, downward in the casing 10. The

bolt 39 is formed with a squared portion 39" sliding in square apertures in the plates 22 and 25, to prevent its rotation and that of a disc 42Y secured upon the bottom of said bolt. this disc being formed with holes loosely enclosing the respective guide-tubes 17 and adapted to abut the flanges 24 on the latter to clamp said guide-tubes in position against the bottom plate 22 of the slide 20 and raise the latter in the casing 10.

ln the operation of the device a supply of washers is placed inthe upper part of the slide 20, constituting the magazine, and the hand-knob 4() is raised. which first lifts the bolt 39 relatively to the sleeve 3st to raise the disc d2 and thereby clamp the guidetubes 17 against the plate 22. The further raising of the hand-knob 40, by contact of the flanges 24 withv said plate` raises said slide and the sleeve 34 seated thereon, relatively to the casing 10, which meanwhile is held down by the handle 11. Thereby, through the cam action of the grooves 35 and rollers 36, a rotation of nearly 90 degrees is given to the sleeve 34, the transfer plate 27 and the agitator 37, agitating the washers in the magazine to cause'them 'to form instacks in the magazine apertures 29, and bringing the several apertures of the transfer plate into registry with those of the magazine. plate to receive therefrom the I prefer to have the magazine apertures 29a11d the discharge apertures 26 spaced a substantial distance apart, in order to secure a substantial movement of the agitator. lVith the hand-knob 40 and the slide 2O elevated. the entire device is then placed upon a mold cavity, the boss 153 entering therein to position the device as a whole, and the hand knob is then forced downward, rst unclamping the guide tubes 17 and lowering them toward the mold pins in advance of the slide. Further downward movement of the hand knob 40, now in contact with the sleeve t, forces the slide 20 downward until the guide-tubes settle in position on the pins 18, the beveled walls of the former coacting with the conical bases of the latter to position the tubes,

and the base plate 22 thereafter seats -uponvl 4the flanges 2A of the guide tubes 17 and clamps the latter in the position 'they have assumed upon the pins. At' approximately the same time, the lowering of the slide 20 80 upon the mold cavity by the handle 11. rlhe disc 42, first rising with respect to the slide,

clamps the guide-tubes 17 against the slide in the relative positions which have been given them by the conical pin bases, and further lifting of the hand-knob 40 carnes the slide and said guide-tubes upward in those relative positions, while the frame structure is still held in place upon the moldcavity, the tubes being thus accurately guided as they are lifted from the pins, in order not to knock the washers therefrom.

Various modifications may be resortedto without departing from the scope of my 1nvention and I do not wholly limit my claims to the specific embodiment shown.
