(on. 36-42) g 1 Claim.
This invention relates to boot and shoe heels and has for its general object to provide a light, inexpensive and durable heel of attractive appearance which can be readily molded by well known means and methods from suitable plastic materials, and which is provided with a normally securely retained but detachable and replaceable toplift. The present case is a division of my prior application filed. March 23, 1939, Serial No. 263,619, which contains claims covering certain features of the heel per so not claimed herein.
The more particular objects of the invention. together with means carried into effect, will best be understood from the following description of certain illustrative embodiments thereof shown in the accompanying drawings, these, however, having been chosen for purposes of exemplification merely, it being obvious that the invention, as defined by theclaim hereunto appended, may be otherwise embodied without departure from its spirit and scope- In said drawings:
Figs. 1, 2 and 3 are a plan view, side elevation m mate n all and front elevation, respectively, of a heel embodying the invention, the toplift being omitted.
Fig. 4 is a perspective view of a toplift for use with the heel illustrated in the preceding figures.
Fig. 5 is a section on the line 5-5 of Fig. 2, showing the toplift in place, and illustrating a further development.
Figs. 6, '7 and 8 are views similar to Figs. 1, 2 and 3, respectively, illustrating a modification.
Fig. 9 is a section taken substantially on the line 9-9, Fig. 6, of the completed heel.
Figs. 10 and 11 are views similar to Figs. 6 and '7, respectively, of a further modification.
Referring to Figs. 1 to 3, the heel therein shown comprises a hollow shell 15 die cast or molded in accordance with well-known methods from a suitable plastic material or composition having the requisite strength, density and hardness, such, for example, as cellulose acetate molding compositions, molding resins, the vinyl acetals and chlorides, styrene, etc. Adjacent its whereby the latter may be assignor to Mo., a
At its lower end the heel or shell'is formed with a socket comprising an opening 18 in its bottom wall, said opening being of smaller cross-sectional area than that of the interior of the heel, and being'surrounded by an intumed flange or wall l9 which, in the construction shown, is reinforced by the web ll.
The socket |8I9, which is of square or other non-circular form, is adapted to receive the similarly shaped shank or stem 20 (Figs. 4 and 5) of a top lift 2|, preferably molded from the same material as that of the shell or heel proper. The stem orshank 23 is formed integral with the toplift 2| and may, if desired, be reinforced by an embedded metallic element, such as a nail 22, Fig. 5. The stem or shank 20 is of such size and shape as to fit sufliciently snugly into the socket Iii-l9 to retain the toplift in place during normal conditions of use while permitting said toplift to be removed and replaced when necessitated by wear without the use of special tools. The retention of the shank 20in its socket may be rendered more secure by applying a coating of rosin, powdered pumice, or other frictional It will be understood that the shell I5 will be formed of a sumciently hard, dense plastic material to give the same, when molded, the requisite durability and surface smoothness. If desired, the heel may be further strengthened and reinforced by filling said shell with an inferior or softer plastic material as shown at 23 in Fig. 5. Such plastic material may be, for example, the plastic composition described in the patent to Griffiths, No. 1,833,618, December 29, 1931, or a upper or heel seat end, where the heel or shell is the largest in cross section, it is stiffened and strengthened by vertical reinforcing ribs I6. Said heel or shell is further stiffened by a vertical reinforcing web I! which extends completely across the same from front to back for substantially its entire height and is preferably Joined at at least one end to one of the ribs material similar to that commonly employed for filling shoe bottoms and composed of ground cork and suitable binder, such as phenol resin.
When a filler 23 is employed, the reinforcing ribs I 6 and web l1, may in some instances be omitted, as in the case of the shell [5a shown in Figs. 6 to 9, although the walls, IQ of the socket for receiving the toplift shank 20 are preferably strengthened and braced by a short reinforcing web 24, as in the case of the shell [5b shown in Figs. 10 and 11.
I claim:
A boot or shoe heel comprising a hollow shell of molded plastic material having a socket and a transverse web reinforcing said socket, and a toplift having a shank received in said socket to retain the same in place.
