PROVISIONAL SPECIFICATION.
A New or Improved Adjustable Brake Block for Cycle Wheel Rim
Brake Levers.
I, ARTHUR HASKINS, of Normanhurst, Woodstock Road, Moseley, in the County
of Worcester, Engineer, do hereby declare the nature of this invention to be
as follows:-
This invention relates to a new or improved adjustable brake block arrange-
ment, which is formed and carried upon the brake levers which impinge upon
the rim of the cycle wheel.
Of late many brake arrangements have been devised to act upon the rim of
the cycle wheel, and in not a few, levers are carried from the front fork upon
each side of the wheel by means of clip brackets and the like. By reason
however of such forks varying in curvature of shape, the brake block-when a
fixed one as is now usual frequently does not lie fair with the rim.
In order to obviate this, I have made this my invention, which consists as
follows:-
The forward end of the lever is shaped with a part circular ledge or step, in
which lies the block or shoe, and the upper or outer edge of such shoe forms the
impinging portion which acts against the rim of the wheel.
This shoe is preferably secured to the forward end of the lever and lying upon
the step portion, by small bolts or pins (one or more) passing therethrough into
suitable slots arranged in the back part of such step portion, or in the shoe
portion or both, so that the shoe portion can be adjustably moved and secured
to accommodate itself to the curvature of the rim of the wheel, and by screwing
up the bolts or pins, securely fixing same in its proper position.

A New or Improved Adjustable Brake Block for Cycle Wheel Rim
Brake Levers.
I, ARTHUR HASKINS, of Normanhurst, Woodstock Road, Moseley, in the County
of Worcester, Engineer, 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 a new or improved adjustable brake block arrange-

page_text: ment, which is formed and carried upon the brake levers which impinge upon
the rim of the cycle wheel.
Of late many brake arrangements have been devised to act upon the rim of
the cycle wheel, and in not a few, levers are carried from the front fork upon
each side of the wheel by means of clip brackets and the like. By reason
however of such forks varying in curvature of shape, the brake block-when a
fixed one as is now usual-frequently does not lie fair with the rim.
In order to obviate this, I have made this my invention, which is illustrated
in the accompanying drawings, in which:-
-
Fig. 1, is a side view of the invention, as applied to the front fork, and wheel
rim of a cycle.
Fig. 2, is a front end view, and Fig. 3, a side view, and Fig. 4, a rear end view
of the invention apart from the wheel and fork.
Fig. 5, is an end view, and Fig. 6, a plan view in detail of the lever end, which
receives the brake block.
Fig. 7, is a detached front view, and Fig. 8, a side view of the brake block.
Figs. 9 and 10, are detailed front and edge views of the front binding plate.
Figs. 11, and 12, are similar detail views of the rear binding plate nuts.
The forward end of the lever 14, is shaped with a part circular ledge or step 15,
in which lies the block or shoe 16, and the upper or outer edge 16, of such shoe
forms the impinging portion which acts against the rim 17 of the wheel.
This shoe is secured to the forward end of the lever and lying upon the step
portion, by small bolts or pins 18, (one or more) passing therethrough into
suitable slots 19, arranged in the back part of such step portion, or may be in
the shoe portion, or both, so that the shoe portion can be adjustably moved and
secured to accommodate itself to the curvature of the rim of the wheel, and by
screwing up the bolts or pins, securely fixing same in its proper position. The
plates 20, are preferably used to receive the pressure of the nut, while the holes
in the plate 21, are screwthreaded to serve as the nuts for the pins.
22, is the usual clip which is secured to the fork 23, for the purpose of carrying
the fulcrum joint pin 24, upon which the lever 14 works.
It will therefore be readily seen that in the attaching of the said brake
mechanism to various machines, the angular position of the brake block may
be easily placed in correct line with that of the rim of the wheel, so that the
pressure shall be true with such rim.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
The improved arrangement and application of adjustable brake block
mechanism, comprising the lever 14, having supporting ledge 15, and slot
holes 19, with block 16, corresponding thereto, and secured by pins 18, as set
forth and shown on the drawings.
