I WILLIAM WILSON HORN of the firm of Horn & Son of 151 Strand in the

This invention relates to an improved rubber sole for boots and shoes and the
object of the said invention is to enable the wearer of the boot or shoe to which
my invention is applied to obtain a better foot-hold of the ground & my improved
sole will consequently be found particularly advantageous when the ground is in a
wet or slippery condition.
My improved sole is made of rubber or any of its several compounds and may be
attached to the boot or shoe in any convenient manner. The wearing surface of
the sole is provided with a marginal flange and a series of cup shaped projections
cach consisting of an outer projecting margin, a central depression and an inter-
mediate ledge or the said cup shape projections may be if desired varied in shape
without departing from the spirit of my invention.

COMPLETE SPECIFICATION.
An Improved Rubber Sole for Boots and Shoes.
1 WILLIAM WILSON HORN of the firm of Horn & Son of 151, Strand
in the County of Middlesex Patent Agent do hereby declare the nature of this
invention (a communication to me from Howard T. Marshall of Brockton County
of Plymouth and State of Massachusetts United States of America, Inventor) and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
This invention relates to boots or shoes and has for its object to provide a new
and useful rubber sole therefor, as will be more particularly pointed out in the
following Specification reference being had to the accompanying drawings, in
which
Figures 1 and 2 are side and bottom plan views respectively and Fig. 3 a cross
section on the line, Fig. 2.
In the drawings A. represents a shoe of which B is the upper and C the outer
sole being secured to the welt E by stitches-a-and all-constructed-as-usual in the
making of boots and shoes, except as to the outer sole which constitutes the present
invention. This outer sole C is made of india rubber or of india-rubber in any of
its compounds and is moided and vulcanized in the usual manner of molding and
vulcanizing articles of india rubber.
Frepresents cavities or depressions in the outer or treading side or surface or
portion of the sole.
Said cavities or depressions are circular in outline and have raised edges or ribs
or rims around them, which edges or ribs project beyond the treading surface or
body of the sole, as shown, making the cavities substantially of a cup shape.
The sole on its outer or treading surface is depressed or made more or less concave
as shown in cross-section Fig. 3, leaving around the edge of the sole a marginal
flauge or rib Kas shown. The cavities or depressions and their raised edges or ribs
or rims are molded and shaped in the mold when the sole is molded, making the
17

page_text: sole complete and finished ready to be applied to the upper. A more or less number
of cavities or depressions can be molded in the sole and they can be of any suitable
shape and form desired-circular, triangular, square, or otherwise-and of any
size and depth. Boots and shoes having soles made as herein described and shown
are particularly adapted for use in yachting as the cavities or depressions cause the
sole to the more closely adhere to the smooth surface of the deck of the yacht,
because of more or less exhaustion of air from the same, as is obvious.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
A boot or shoe sole of india-rubber or any of its compounds, having its wearing-
surface provided with a marginal flange and a series of hollowed projections each
consisting of an outer-projecting margin a central depression and an intermediate
ledge, substantially as described.
