Specification of Letters Patent.

Patented Sept. 10, 1918.

Application filed April 21, 1916. Serial No. 92,612.

To all whom it may concern:

Be it known that I, ELIEL L. SIIARPNECK, a citizen of the United States. residing at \Vinthrop, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Heel-Molds, of which the following is a specification, reference being had to the accompanying drawings, forming part thereof.

This inven ion has reference to improvements in machines for manufacturing heels for boots and shoes.

One object of the invention is to provide an improved heel forming machine from which the heel may readily be removed.

Other objects of the invention will appear from the following description.

The invention consists in the novel heel forming machine as will hereinafter be more fully described and pointed out in the claim.

Figure 1, represents a plan view of the improved heel forming machine.

Fig. 2, represents a sectional view taken on line 22 Fig. 1.

Fig. 3. represents a sectional view of the machine, on line 33 Fig. 1.

Fig. 4, represents the heel in side elevation.

Fig. 5, represents a front view of the same, and

Fig. 6 represents a top plan view thereof.

Similar characters of reference designate corresponding parts throughout.

As shown in Figs 1 to 3 inclusive of the drawing 10 indicates the base or bed of the machine which bed or base is adapted to be mounted on a work bench or on any similar support. At the upper portion of said bed 10 and preferably integral therewith is the form 11 having the upper inclined surface 12, the bevel edge 13 and the bevel edge 14 which latter conforms approximately to the shape of the to of the proosed heel and varies in wi th from the bevel 13 to the rear portion 15. Said base 10 has also the pins 16, 16 and, at one end, the posts or studs 17, 17 transversely slotted near their upper ends and provided with the key 18.

Pivotally mounted on the base 10 is the mold member 19 having at one end a neck or extension adapted to be received between the studs or posts 17. 17 of said base 10. This mold member 19 has the side extenand a surplus of said material may 13 of member 11, and the downwardly flaring curved wall 24 the lower ortion of which embraces the edge 14 of said member 11 and cooperates therewith to constitute the bevel flaring channel 25. The upper smaller end of the mold chamber has a seat and is partially closed by the funnel and guide member 27 which is seated in said seat and has the cars 28. 28 furnished with bolts or screws 29, 29 which are secured in screw threaded perforations of the mold member extensions 22, 22.

In the bore of the guide member 27 is slidable the plunger 30 which may be of any suitable length and. at its upper end has the cars 31. 31 between which is pivotally secured the pressure lever 32 one end of which is pivotally connected with the link 33 and this link 33 is pivotally connected with a member of the neck of mold member 19.

\Vith the parts of the machine in the positions shown in Fig. 1 lever 32 is first raised to withdraw plunger 30 from the bore of guide 27 clear of the upper funnel end of said bore. Material from which the heel is to be molded. is now supplied to the mold through the bore of the guide member 27 extend into said bore to a height depending somewhat upon the compressibility of said material. This material is preferably of a consistency to be received in the channel of the mold and may contain leat her scraps or other wear resisting material and a binder the whole being adapted to be compressed and to set or adhere to constitute a heel.

After the mold has thus been supplied with material, plunger 30 is replaced in the bore of guide member 27 and pressure is applied in a suitable manner to lever 32 to force downward plunger 30 in order to effect the compression of the material. Such pressure mold to set or. after such pressure is applied, the molded heel may be retained 1n the mold for a suitable eriod to permit the material to set suflicient y to retain its shape after removal of the heel from the mold.

When it isdesired to remove the heel from the mold key 18 is withdrawn and that end of the mold member 19 having the neck is swung upward and, after a suitable point has been reached by suchmold member 19 in its swinging movement, pressure is again applied to the lever 32 whereby plunger 37 acts to push the newly molded heel from the molding cavity of said member 19, the curve of the heel breast followin the curve 23 of the mold somewhat and t e heel swinging away from the mold wall 24. After the heel has thus been removed or pushed from the mold, the mold member 19 is swung back into place against this base 10 with its neck between the posts 17, 17 and the key 18 is replaced in the slots of said posts to hold said neck.

The product of said machine as a result of the above operation is the heel body shown in Figs. 4, 5 and 6 of the drawings which may be supplied with the usual wearing lift L indicated in Figs. 4 and 5. Such improved heel when made of suitable moldable material requires very little if any finishing and in some cases need not be covered. The shape of the heel is such that the heel breast a. meets the flat seat I) on a straight transverse line adapted to bear against a sole without the necessity of trimming said sole while the edges of said heel breast a eatend upward at the sides of the seat I) to form the ends 0, 00f the upstandin flaring lip d which conforms exterlorly to t e shape of the heel and interiorly to the she e of the to conseat 6 whereby said lip d is adapt fine and finish the edge of that portion of a sole seated in or on said seat b without the necessity of unduly skiving the edge of said.

sole.

By such molding process I am able to construct a heel having the seat b and the lip dintegral .With said seat and with-said heel without cutting the heel and I find that the lip (Z when m'olded as an integral part of the heel and its seat is stronger and more desiring a heel shaped cavity one end of which receives said form, means to pivotally connect said mold member and said .base, a funnel guide mounted at the other end of said cavity, a plunger slidable in said guide, a lever connected with said plunger and a pivoted link connecting said lever an said mold member.
