as follows:-
Consisting of a suitable shaped piece of thin metal, which is made oval or angular,
on this piece of thin metal is a boss or projection, with a D shaped hole in centre,
in this shaped hole is inserted the brake plunger tube, which is made secure,
with a screw of suitable size and shape. On each side of the raised boss are two
or more holes for the purpose of attaching a shoe, which is made of rubber or any
other suitable material, on this shoe are two or more studs with rounded heads,
which are pressed through the holes in the metal plate, which clinch themselves
of their own accord when pressed, the edges of the shoe are flanged all round
for the purpose of stopping any displacement of the shoe when pressure is put
on same.

I, WILLIAM ROGER MCTAGGART, of 55, Aungier Street, Dublin, in the County
of Dublin, Ireland, Cycle Manufacturer, do hereby declare the nature of this
invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
This invention refers to certain improvements in cycle brakes, and relates more
especially to the brake spoon.
According to this invention, I form the brake spoon of a suitably shaped piece
of thin metal, which is made oval or angular. On this piece of thin metal, which
forms the spoon, is a boss or projection with a D shaped hole in its centre. In
said D shaped hole is inserted the brake plunger tube, which is made secure by
means of a screw. I attach a brake shoe, of rubber or other suitable material
to the said metal spoon in the following manner. On each side of the raised boss
are two or more holes, and on the said shoe are two or more corresponding studs with
rounded heads, which clinch into the aforesaid holes when pressed into them.
The edges of the said shoe are flanged all round to prevent displacement of the
shoe when pressure is applied.
In order that my said invention may be more fully understood, I will now

page_text: proceed to describe the same with reference to the drawing accompanying this
specification, in which Fig. 1 shews elevation of brake-lever, brake rod, plunger
tube, and spoon; Fig. 2 is a side elevation of lever fulcrum clip, Fig. 3 is a plan
of plunger guide, with mud guard attachment combined, Fig. 4 elevation of same;
Fig. 5 elevation of brake spoon fitted on plunger tube, Fig. 6 side view of brake
spoon, Fig. 7 elevation of shoe, and Fig. 8 plan of same, Fig. 9 plan of D shaped
projection on plunger tube.
Figure 1 is drawn to a smaller scale than the rest of the figures.
The same letters of reference are employed to denote the same parts in all the
views.

Jj are projecting studs (of which there may be more than two) on the shoe i.

flange m all round to prevent displacement of the shoe when pressure is applied.
A D-shaped hole in the boss n of the detachable spoon allows the latter to fit
on to the D-shaped projection at the lower end of the plunger tube d. It is held
in place by a screw o, screwing into the bottom of the plunger tube d.
is the ordinary brake spring.
r is a collar to confine the said spiral spring ? on the plunger tube d.
Constructing cycle brakes according to this invention, the plunger tube being
detachable from the spoon or shoe frame allows the spiral spring to be slipped up
to the collar, and the plunger guide to be slipped on to the plunger tube, thus when
the metal spoon or shoe frame is attached by means of its screw, the whole is held
securely in position.
The shoe being easily detachable can be replaced by a new one when worn out.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
1. In cycle brakes the method of attaching the metal spoon to the plunger tube,
for the purpose set forth.
2. In cycle brakes the use of a detachable rubber shoe, in combination with a
or shoe frame.
metal spoon
3. In cycle brakes, the use of a detachable rubber shoe, provided with studs on
its surface for taking into holes in the brake spoon or shoe frame.
4. In a detachable rubber shoe, such as that described, forming the edges of
said shoe with a flange all round for the purpose set forth.
