A New or Improved Construction of Shoe Blocks for Brakes, Tyres for
Wheels, and other Wearing Surfaces.
I, WILLIAM FOSTER, of Skinner Lane, Leeds, in the County of York, Leather
Manufacturer, do hereby declare the nature of this invention, to be as follows:-
The object of my invention, is to construct shoe blocks for brakes, in a simple
and efficient manner, and by the employment of my invention the said blocks may
be produced at a very small cost.
According to my invention, I employ scrap leather, which I cut to the shape of
the cross section of the block to be produced. These scraps when cut to the required
shape are nailed or otherwise fastened together one on the other, until a block is
produced having its side surface composed of the edges of the leather. The leather
may have two or more pieces in each layer, if desired, and by making the section
of a dovetailed form, the said blocks may be slipped into a dovetailed shoe and
quickly fastened in position by means of a pin or other fastening. Instead of
forming the blocks with the leather pieces placed crossways to the block, the said
pieces may be placed longitudinally with practically similar results.
When employing my invention for tyres of wheels, the pieces of leather are
fastened together side by side round the rim of the said wheel, so as to present
the edges of the leather to the road as a wearing surface.
It will he readily seen that the blocks and tyres constructed as above described,
are capable of standing a large amount of wear, as the scraps of leather cannot come
apart and they form a solid leather surface which can be worn down to its very
base.

A New or Improved Construction of Shoe Blocks for Brakes, Tyres for
Wheels, and other Wearing Surfaces.
I. WILLIAM FOSTER, of Skinner Lane, Leeds, in the County of York, Leather
Manufacturer, do hereby declare the nature of this invention and in what manner

page_text: the same is to be performed, to be particularly described and ascertained in and by
the following statement:
The object of my invention, is to construct shoe blocks for brakes, tyres for
wheels, and other wearing surfaces, in a simple and efficient manner; and by the
employment of my invention, the said blocks may be produced at a very small
cost.
In order that my invention may be clearly understood, and readily carried into
effect, I will proceed to describe same with reference to the accompanying drawing,
in which similar letters refer to like parts in all the figures.
Figures 1 and 2 are sectional perspective views, and Figure 3 is a cross section
shewing my invention applied as a shoe block for use as a break for wheels.
Figure 4 is a cross section of a wheel tyre constructed according to my invention,
and Figures 5 and 6 shew respectively longitudinal section and plan of a modifca-
tion of the invention as applied to a tyre for a wheel or pulley.
According to my invention, I employ pieces of waste or scrap leather which are
cut to the shape of the section required. These scraps when cut to the required.
shape, are nailed or otherwise fastened together in layers, until a block is produced
having its surface composed of the edges of the leather pieces. Each layer may
be composed of several pieces of scrap leather, or they may be made of pieces cut
to the shape of the entire section to be formed. Blocks of this description are
illustrated at Figures 1 and 2, which are built up of leather pieces A and B and
whose edges form a working surface C; and the blocks composed of the leather
pieces A and B are cut to a dovetailed shape at K, so as to enable them to be easily
fitted to shoes D and E which have dovetailed recesses F in same. The shoes D
and carrying blocks, are especially suitable for use as brakes for wheels, and if
desired the dovetailed recesses F may be made slightly taper so as to enable the
blocks to be firmly clamped on being forced into the same. Figure 3 illustrates
a block composed of pieces of scrap leather A and B as above described, but in this
ease the dovetailed portion K is composed of a piece of wood or other suitable
material which is screwed or otherwise fixed to the underside of the block. In
Figure 4, G is a metal or other felloe of a wheel, and the pieces of leather A are
placed in the dovetailed recess F and nailed or otherwise fastened one against the
other, until a solid leather tyre is made up round the entire wheel. In Figures 5 and 6
the leather pieces are placed longitudinally on the surface of the wheel. This
result can be attained by forming several blocks H of a length equal to the width
of the tyre required, and driving these blocks into dovetailed recesses F situated
on the periphery of the wheel J. This arrangement is especially applicable for
forming a wearing surface for driving or polishing pullies.
It will be readily seen that the blocks and tyres constructed as above described,
are capable of standing a large amount of wear, as the scraps of leather cannot
come apart and they form a solid leather surface which can be worn down to the
very base.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to he performed, I declare that what I
claim is:
1. The construction of shoe blocks for brakes, tyres for wheels, and other wearing
surfaces, composed of pieces of scrap leather secured together face to face, so as
to employ the edges of the leather as the wearing surface, substantially as and for
the purposes set forth.
2 The leather blocks formed of pieces nailed or otherwise secured together,
and provided with dovetailed lower portions, in combination with shoes or felloes
having dovetailed recesses in same, substantially as and for the purposes set forth.
The general arrangement, construction and combination of the parts forming

page_text: my new or improved construction of shoe blocks for brakes, tyres for wheels, and
other wearing surfaces, substantially as and for the purposes set forth.
Dated this 28th day of June 1897.
