MOLD FOR FORIVIINO BOOT OR SHOE- HEELS.

SPECIFICATION forming part of Letters' Patent No. 322,301l dated July 14, 1885.

Application filed May 2, 1885.

T0 all whom, it may concern: 1

Be it known that I, EDWARD J. LE GAY, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Molds for Making Boot and Shoe Heels, which will, in connection with tlieaccompanying drawings, be hereinafter fully described, and specifically defined in the appended claims.

This invention has for its object the production of molds by which to mold, fromsuitable moldable material, a shell or wall for the heels of boots and shoes, and also, after such shell or wall is properly dried and set to form, to mold, compress, and set therein a filling-block of wood or other suitable material and an interposed layer or body of adhesive cement, which firmly connects together such outer wall and its filling-block, all as by aid of the accompanying drawings will be hereinafter described and claimed.

In said drawings, Figure 1 is a'plan view of the respective parts A B C of the mold, the same being shown as disconnected, but in proper relative position to be assembled or connected together for operative action. Fig. 2

is a longitudinal central vertical section of part A of the mold, taken on line X X, Fig. 1. Fig. 3 is an end elevation of said part A, taken as viewed at the right in Fig. 1. Fig. 4 is a side elevation of said part B, taken as viewed fromthe near side in Fig. 1, or as viewed from the lower end of the sheet. Fig. 5 is an elevation of said part C, taken as viewed from the left in Fig. 1. Fig. 6 is an elevation of said part C, taken as viewed from the near side in Fig. 1, or as viewed from the lower end of the Sheet. Fig. 7 is a side elevation of part D of the mold, which replaces part B when inserting the wood iilling in the previously-molded shell of the heel, said view corresponding to that of part B in Fig. 4. Fig. 8 is a transverse vertical section taken as on line Z Z, Fig. 1, but showing the respective parts of the mold and the molded outer wall of the heel in their proper relative positions. Fig. 9 is a longitudinal vertical section of the parts shown in Fic. 8, taken as on line x as, Fig. 1. Fig. 10 is an inverted or underside plan view of the compressor employed with my mold. Fig. 1l is a view like Fig. 9, but

(No model.)

showing a change in the form of the molds for overarched breasts of the heels, and an iml part of cavity a in body A, and to act upon the interior of the shell or wall of the heel when being molded in said cavity. Abase-or An interior mold, B, is` lformed in its upper portion c as a counterlower portion, d, of said mold B Iills the lower portion of the cavity in exterior mold, A, in which, for convenience of construction, the

cavity is carried directly through from `top to bottom. l

For the purpose of molding the breast of the shell of the heel, I employl the follower C, which by its lugs f is interlocked in grooves g of mold A, and which is formed with an overhanging portion, h, which, when the several parts ofthe mold are brought together, extends over the projecting lower portion j of mold B, as shown in Figs. 9 and 11, the lower portion z' of the follower being then close to part d of said mold B.

For the purpose of parts of the mold together aft-er the blank has forcing the respective been inserted therein for molding, I employ a strong metallic hoop or clamp, E, whose longer sides Ic k are vertically parallel, (as are the side walls of the mold,) but whose ends ZZ are y is then forced downward upon the mold by a cap, a, actuated by plunger p of a press, or by other effective means. the clamp E forcing the parts of the mold together by the action ol' the described inclines tillthe blank is y molded tov the eXact form of cavity a in outer mold, A, and of portion e of interior mold, B, and the adjacent faces of the breast of said portion c and corresponding part of portion n, as shown in Figs. 8, 9, and 11.

As above stated, the rear and side walls of the heel-shell are molded between molds A and B, the breast is molded between B and C, and the bottom between B and cap n. As shown in Fig. 9, the breast of the heel is a right line, while in Fig. 11 it is formed with an overarching curve.

For the purpose of securing the heel-blank in position, while parts A B G of the molds are being forced together by clamp E, I arrange in stem p of cap a a spindle, 8, which is secured by pin 9, passing through a slot in 8, as indicated by dotted lines, and so as to allow said spindle to be thrust out by the action of spring 11 to the extent of said slot, so that before the cap a is in contact with clamp E the foot on spindle 8 will engage the part of the heel-blank b which is folded over the upper face of B, and by the action of said K spring will secure the same in position till cap f been placed therein, it is necessary to subject the saule to moldingpressure, in order to give the requisite seat in the top for the heel of the wearer 5 and as part B cannot be employed for such purpose I provide part D, the lower part of which corresponds to part d of B, while its upper portion 7 is of the proper contour and relief to duly form the seat for the heel of the wearer.

In my application No. 152,947, filed Jann ary 15, 1885, are shown heels such as my molds are especially adapted to produce; and I re fer to said application and the patent that may issue thereon as illustrating the product of the molds herein described and claimed.

I claim as my invention- 1. A heel-mold formed with part A, having` a recess, a, corresponding to the rear and side walls of the heel, part B, having portion c of a size and form corresponding to the cavity in the heel-shell when it is i nsertedm in cavity a, and follower C, formed with part h, corresponding to the front of part B, substantially as specified.

2. The combination, with parts A C of a heel-mold formed as specified, of cap D, having portion 7, adapted to t and forni the concave upper face of the heel-iilling when molding the lling-block and cement therein, sub stantially as specified.

8. The combination, with a mold formed with parts A B C, having form and adapta tion to mold and set to form the shell or wall of boot and shoe heels, and with parts A and C, having oblique outer ends, as specified, of band or clamp E, having corresponding internally-oblique ends, and adapted to force together the respective parts of the mold and position, substantially as speciiied.

5. rIhe combination, with parts A B C of the heel-mold, clamp E, and plunger p, with its cap n, of sliding stem 8, its foot 10, and extending spring 11, all substantially as speciied.
