PROVISIONAL SPECIFICATION.
Improvements in Brakes for Cycles.
I, EBENEZER ILLINGWORTH, of 11, Bank Street, Bradford, in the County of
York, India-rubber Goods Manufacturer, do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements in india-rubber covered brakes or brake
blocks of bicycles, tricycles, and other cycles or velocipedes particularly applicable
to pneumatic tyres and its object is to facilitate the attachment and removal of the
blocks.
For this purpose I form a horizontal groove of dovetail section in the face of the
block shoe or spoon which groove is narrower at the front or tapers from back to
front. And I form a similar shaped projection at the back of the brake block to fit
said groove. By this formation the application of the brake tends to tighten or
wedge the block in position.
The block is preferably made of soft rubber on the face so as not to injure the
tyre and the back or part engaging the shoe is preferably made of hard rubber.
Instead of india-rubber other suitable material may be employed.
Dated this 20th day of February 1893.

COMPLETE SPECIFICATION.
Improvements in Brakes for Cycles.
I, EBENEZER ILLINGWORTH, of 11, Bank Street, Bradford, in the County of
York, India-rubber Goods 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 relates to improvements in india-rubber covered brakes or brake
blocks of bicycles, tricycles, and other cycles or velocipedes particularly applicable
to pneumatic tyres and its object is to facilitate the attachment and removal of the
blocks.
For this purpose I form a recess or groove of dovetail section in the face of the
brake shoe or spoon which groove is narrower at the front or tapers from back to
front. And I form a similar shaped projection at the back of the brake block to fit
said groove. By this formation the application of the brake tends to tighten or
wedge the block in position.
The block is preferably made of soft rubber on the face so as not to injure the
tyre and the back or part engaging the shoe is preferably made of hard rubber.
Reference is to be had to the accompanying sheet of drawings forming a part of-
this Specification, in which similar letters of reference indicate corresponding parts
in each of the figures.
Figure 1, represents the front wheel of a safety bicycle fitted with my improved
brake shoe.
Figure 2, represents a separate side view of the brake shoe on a larger scale.
Figure 3, represents a cross section of the same on the broken line a, 6 of the
former figure.
Figure 4, represents a plan view.
Figure 5 consents a longitudinal

page_text: Figures 6 and 7 are separate back views of the brake shoe and brake block
respectively.
The metal shoe or shell A is preferably made of sheet metal and is brazed or
otherwise secured to the usual brake rod B. This shell is formed with a recess C
in its underside of dovetail section slightly tapering from back to front and
preferably closed at the front by the lip D. The block E of soft rubber has a hard
rubber back F of dovetail section vulcanized to it and this vulcanized portion fits
into the dovetail recess in the shoe and so retains the block in position whilst the
taper form of the recess enables the wedge to be tightly fitted in with little
trouble.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, declare that what I
claim is :
1. In a cycle, an india-rubber brake block having an acting face of soft rubber
vulcanized to a hard rubber backing adapted to be secured upon the shoe,
substantially as herein shown and described.
2. In a cycle, the combination with an india-rubber brake block of a brake shoe
having a recess of dovetail-shaped cross-section adapted to receive and retain a
similarly shaped hard rubber projection on the back of the brake biock, substantially
as herein shown and described and illustrated in the accompanying drawings.
Dated this 20th day of November 1893.
