Description
@einem @twineY FREDERICK MASHEPARD, OF'NEW YORK, N. Y.
Letters Patent No.' 1100,67 7 :lated March 8, 1870.
IMPROVEMENT IN HEELS OF RUBBER BOOTS AND SHOES.
` The Behec'lule referred to lx1-these Letters Patent and making part of the same To all` whomit may concern Be itimown that LFREDERICK M. SHEPAnD,of
the, city, county, and State of NewYork, have invented a new and useful Improvement in the Heels of India-Rubber Boots and Shoes; and I `do hereby deelare that the following is a full, clear, and exact descripton thereof', reference being vhad to the accom.- t panying drawings 'making part of this specification, in whcl1 l l Figure 1` is an 'elevation ot'. the heel-part of a `boot on my improved plan; l
i Figure 2, a face view;
Figure, 3, a vertical section; .and Figure 4, a separateview'in elevation of the heelplate.
The same letters indicate like parts in all the figures. n l p The heels of vulcanized India-rubber boots, particularly the rear part, wear oi more rapidly than the sole, and soon wear down to about the same thickness 'as the sole, and as the heels, like the rest of the boot,
are formed while the compound -of India rubber and sulphuris in the green or plastic state, and then vulcanized, it has been found difcult to apply to such heels material that will better stand the wear. Q
'The object of my invention is .to remedy this defeet, and tothis end 1` n'lake asuitable heel-plate, a, of the form of the lower =part of vthe heel of the boot,
from the' inner surface of which plate projects aseries ofstems, b, and 'this plate isl combined with the intended heel c while the compound of India rubber and i sulphur is inthe greefn or plastic state For the 4,convenience of casting, these vstems are cast to' project' at right angles vto the plane of the platefandflaiterbeing softened by the well-known process for rendering cast-iron malleable, the stems are all bent inward, as represented.
The plate so prepared is putinto a mold such'as used for molding the heels for'India-rubber boots, and
the vulcanizable'compouud of I ndi'a rubber in the plastic state forced into the mold among and around the stems and into-the' apertures of the plate it' there be any. After the heel is so formed by combining the block of rubber compound l with the metal plate a and stems b, it is applied and caused to adhere to the boot or shoe e in the usual manner 'and then vulcanized.
I prefer to make the metal plate. with its stems of what is known of malleable cast-iron, so that the stems can be easily bent, but other metals may be used, and the ends may be split and clinched by bending or otherwise,as shown in fig. 5, and imbedded' into the surface of the rubber, or the stems maybe formed with heads at their extremities, as shown in tig. 6, or the stems may be made shorter than the thickness ol' the intended'heel, hollow at their outer ends, and tapped to receive screws with heads, asV shown at iig. 7, butI do not wish to be understood as limiting my claim of invention to the use of such metal; nor to the making of the stems with split ends, as described, as these may be varied within the compass of my said invention. e l
`I do not claim, broadly, plating the heels of Indiarubber' boots or shoes with metal, by applying the metalto the India-rubber heel While in` the plastic lstate and then vulcanizing the India rubber; but
