TO THE FISK RUBBER PORATION OF MASSACHUSETTS.

0F MILWAUKEE. WISCONSIN, ASSIGNOR, BY MESNE ASSIGNMENTS, COMPANY, OF CHICOPEE FALLS, MASSACHUSETTS, A (JOB- MOLID FOR MAKING RESILIENT HEELS.

To all whom it may Be it known that siding at Milwaukee, State of Wisconsin,

ooncem:

I, EDWIN C. Wmsn, re-

county of Milwaukee, have invented certain new and useful Improvements in Molds for Making Resilient Heels;

the following to be a full, clear,

description.

This invention relates mg resilient character which are adapted to be of which I declare and exact to molds for makheels, particularly heels of that formed forming operation.

A further object provide a device of this of the invention is to character which is of simple construction and eflicient in operation.

A further object of t provide a device of this concavo-convex mold his invention is to character having a chamber wherein means are provided for suitably supporting the washers in the molds so that the washers are located substant the adjacent concave surface of the Further objects of the ially parallel with mold. invention relates to economies of manufacture and details of construction as will herei nafter appear from the detailed description to follow.

The objects of the invention are accomplished in one instance by the devices and means described in tions, but it is evident th the following specificaat the same may be varied widely without departing from the scope of the invention as pointed out in the appended claims.

A structure constituting one embodiment of the invention. ferred, is illustrated 1n drawlng forming a part which may be the prethe accompanying hereof in which:

Figure I is a top plan view of a portion of the mold with the cover removed.

Figure 11 is a vertical sectional view through a portion of the mold, taken along the lines 11-11 of Figure I. 7/

Figure III is a bottom plan view of the finished heel.

Figure 1V is a sectional view through the finished heel. taken along the lines IV-IV.

of Figure III.

Figure V is a sectiona 1 view through the Application filed July 30, 1919. Serial No. 314,324.

finished heel in the position which it 00- cupies when it is applied to the heel of a shoe.

Referring to the drawing, similar reference characters designate the corresponding parts throughout the several views, and the sectional views are taken looking in the direction of the small arrows at the ends of the section lines.

In the embodiment (f the invention illustrated herewith, 1 indicates the base member of the mold which is provided with a plurality of concave recesses 2 formed therein, each of which conforms to the outline of heel which it is desired to construct.

plurality of pins 5 are positioned at suitable points in the base member and extend upwardly therefrom for the purpose of securing the intermediate and top members of the mold in proper position relative to base member so that the recesses and projections carried thereby will suitably register with the concave recesses formed in the base member. Positioned above the base member and retained in position relative thereto by means of the pin 3 is an intermediate member 4, which is provided with a plurality of openings extending therethrough each of said openings being formed to conform with the outline of the heel which it is desired to construct. The concave recesses formed in the surface of the plate 1 are each of substantially spherical form, and a plurality of washer supporting devices 5 are suitably mounted within the base plate and extend upwardly therefrom so as to project above the concave recesses formed in the upper surface of the base plate. Each of the washer supporting devices 5 is provided at a point adjacent the end portion thereof which projects within the mold chamber with an enlarged portion 6 which is adapted to support a small washer 7. The several washer supporting devices are positioned in the base plate to extend substantially parallel with each other as they project Within the mold chamber. The enlarged portions 6 of the washer supporting devices are constructed to support a washer thereon so that the plane of the washer is substantially parallel with the concave surface at the point where the concave surface most closely approaches the washer, or to the tangent to the concave surface at the point where the rality of openings sembled in concave surface most closely approaches the Washer. In other words, the washers are carried by the supporting devices so that the plane of each washer except that washer which-is located at substantially the heel center 'is somewhat inclined to the longitudinal axis of its supporting device whereby the circular edge of each washer has every point thereof located at a substantially equal distance from the concave surface of the base plate.'

Theupper member 8 of the mold isprovided at suitable intervals throughout one surface thereof with a plurality of convex depressed portions 9 adapted to register with the openings formed in the intermediate plate when the top member is suitably positioned thereon so as to form a plurality of mold chambers 10, each of which is substantially concavo-convex throughout a portion of its extent. The top plate or member of the mold is also provided with a plu- 11 formed therein which are suitably positioned to register with and receive the upper end portions of the pins 3 so as to cause the top member to suitably register with the intermediate and base members of the mold when these members are arranged in superposed position.

When the various mold sections are asplurality of mold chambers are provided, each of which is substantially concavo-convex throughout a portion of its extent, and the parts are arranged in such a manner that the washer supporting devices carried by the base plate project within each of the mold chambers and terminate a substantially equal distance short of the convex surface of the top plate. In the practice of the invention the several plates are superposed to have the corresponding parts subjected to the necessary. degree of heat .heels for vulcaniz'ing the rubber in the mold chambers. After the completion of the vulcanizing operation the plates forming the mold are separated from each other, the being retained in position within the openings formed in the intermediate plate from'which they may be forced in any desired manner. a

position it will be seen that a,

that by positioning the washer supporting devices in the base plate so that their longitudinal axes are in substantial parallelism that portion of these devices which project within the mold chambers may be readily Withdrawn from the completed heel, while the washers supported by the said devices remains embedded within the rubber of the heel. As the washers are carried by the supporting members so that they are all positioned a substantially equal distance from the convex surface of the cover memher, and substantially parallel to a plane tangent to where it most nearly approaches the washer the concave portion at the point it results that the washers are positioned a substantially uniform distance from the upper surface of the completed heel and are substantially parallel with the upper surface of the heel when such heel has been ap plied to a plane surface.

. It will be seen upon reference to Figures III and V of the drawing, that the completed heels are each provided with a plurality of the washers 7 each washer being located a substantial equal distance from the upper surface of the heel, and openings 12 are formed in the in registry with the openings in the washer to provide means for readily inserting the necessary fastening devices for securing the rubber heel in position upon a shoe.

While the invention is shown and described in considerable detail it is to be understood that this showing and description is illustrative only and for the purpose of rendering the invention more clear, and the invention is not to be regarded as limited to the precise details of construction illustratednor described except in so far as such limitations are the following claims, in which it is my in tention to claim all novelty inherent in my invention broadly as well as'specifically.
