1, GEORGE BAXTER, of 1 Frederick's place, Old Jewry, in the City of London,
Gentleman. do hereby declare the nature of my said invention to be as follows
The object of my invention is to effect improvements in that form of brake
for cycles and the like for which I have obtained Letters Patent No 18,650 dated
5th October 1895 and consists in rendering the same adjustable and capable of
being acted upon from the usual handle bar brake lever.
According to my present invention, I form the brake action separate from
the clamp and provide the latter with a bearing plate to which the support of
the brake action is attached. The support may be formed to encircle the bearing
plate or may be connected thereto by a dovetail or analogous connection, a screw,
bolt, clamp or other means being provided for securing the support in its
adjusted position on the bearing plate. By these means the rollers of the brake
action may be arranged to act on any portion of the side of the tyre or the rim,
and renders the brake adjustable to the varying distances between the fork
crown or bridge plates and the tyre of the wheel."
In order that the brake may be operated from the handle bar by the usual
brake lever and plunger rod or tube, I provide a lever suitably pivoted at one
end to the moving portion of the brake action, the other end acting as the
fulcrum against a suitable fixed boss or other support. The plunger rod or
tube is pivoted to the lever between the ends at a convenient point so that when
pressure is applied to the brake lever the brake is applied in a similar manner to
when pressure is applied by the foot as described in my said former Letters
Patent.
I also form the brake action with two foot plates, instead of one, so as to act
as footrests, one of which is capable of applying the brake.

in and by the following statement:

According to my present. invention, I form the brake action separate from the
clamp and provide the latter with a bearing plate to which the support of the
brake action is attached. The support may be formed to encircle the bearing
plate or may be connected thereto by a dovetail or analogous connection a screw,
bolt, clamp or other means being provided for securing the support in its
adjusted position on the bearing plate. By these means the rollers of the brake
action may be arranged to act on any portion of the side of the tyre or the rim
and renders the brake adjustable to the varying distances between the fork
crown or bridge plates and the tyre of the wheel.
In order that the brake may be operated from the handle bar by the usual
brake lever and plunger rod or tube, provide a lever suitably pivoted at one end
to the moving portion of the brake action, the other end acting as the fulcrum
against a suitable fixed boss or other support. The plunger rod or tube is
pivoted to the lever between the ends at a convenient point so that when pressure
is applied to the brake lever the brake is applied in a similar manner to when
pressure is applied by the foot as described in my said former Letters Patent.
I also form the brake action with two foot plates instead of one, so as to act
as footrests, one of which is capable of applying the brake.
And in order that my said invention may be particularly described and
ascertained, reference is hereby made to the accompanying drawings in which
similar figures of reference indicate corresponding parts.
Fig 1 is a front elevation
Fig 2 a side elevation
Fig a plan view, and
Fig 4 a front elevation showing the brake partly depressed.
5 is one portion of the brake frame, which is pivoted at 6 to the support 7
capable of adjustment relatively to the clamp 8 in order that the brake may be
adjusted to the varying distances between the fork crown and the tyre of the
wheel. 9 is the other portion of the brake frame which is pivoted at 10 to the
support 7. Both portions and 9, carry projecting axles 11, 11, on which are
mounted the rollers 12, 12, formed of rubber, wood, leather or other material
suitable for the purpose. The part 9 preferably works in a slot formed in the
lower portion of the frame 5, which slot serves to return the part 9 to its normal
position after use. In order to cause the part 9 to be depressed simultaneously
and similarly with the part the latter is provided with a projecting edge 13
arranged to act upon the upper edge of the part 9 whereby the latter is depressed.
A spring 14 is contained in the support 7 for returning the brake. frames to
their normal position when pressure is removed, the spring acting between the
support 7. and the underside of a projecting flange 15 formed on the
part 5, (Fig 3).
In order that the brake may be operated from the handle bar, I provide the
plunger rod or tube 16 pivoted to a lever 17 which is pivoted at 18 to the frame 5
the part 19 of the lever 17 acting as the fulcrum against the fixed support ?
or a fixed boss on the part 5 as shewn in Figs 1 and 2. The frame 5 is provided
with a pair of foot rests, one of which 20 may be used to apply the brake with
or without the use of the plunger rod or tube 16.
Fig 4 shows this arrangement with two foot rests, one of which is partly
depressed.
As before mentioned, the support 7 is adjustable relatively to the clamp 8.
This is effected by providing the clamp with a bearing plate 21 formed with
recesses or holes 22 with which a screw 23 engages. The screw passes through

page_text: the support 7 which may encircle the bearing plate or may be fitted thereto, as
shewn in Fig 3, by a dovetail connection.
The improved brake is attached to the cycle by a clamp 8, preferably
surrounding the steering stem or pillar between the crown or bridge plates as
shewn by dotted lines in Fig 2 the dotted lines indicating a portion of a fork and
steering stem.
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. The new or improved brake for cycles and other road vehicles, constructed,
arranged and operating substantially in the manner as hereinbefore described
and illustrated by the drawings.
2 In a cycle or other analogous brake, the application and use of a clamp 8
provided with a bearing plate 21 and recess 22, support 7 and screw 23 for
adjustably supporting the brake action, substantially as herein before described
and illustrated by the drawings.
3 In combination with the frames 5, 9, carrying rollers 12, 12, the application
of the lever 17 pivoted to the frame 5 at 18 operated by the plunger rod 16, from
the handle bar, substantially as hereinbefore described and illustrated by the
drawings.
4 The combination, with the frames 5, 9, carrying rollers 12, 12, of the
bearing plate 21 and support 7 adjustably arranged relatively one to the other,
substantially as and for the purposes hereinbefore described and illustrated by
the drawings.
