PROVISIONAL SPECIFICATION.
Improved Means for Holding On Velocipede and other Brakes.
I, JOHN TIMOTHY BROWN of 5 St. Mary's Butts, Reading in the County of
Berks., Whitesmith, do hereby declare the nature of this invention to be as
follows:-
In this invention the rod which controls the brake terminates in, or is attached
to a rack or toothed plate, which slides through a small lock in which is a spring
catch which engages with the teeth of the rack. The lock is clamped on to the
handle bar or is attached thereto or to any convenient part of the machine.
To release the catch a trigger or spring button and pin are provided, which being
touched disengages the catch and the brake is at once released, and returns to its
rest position.
The lock contains also a coarse worm screw with square head, the end of which
comes close up to the spring catch so as to regulate its travel and adjust its contact
with the rack. This screw is moved forward or backward by a small key in the
usual way.

COMPLETE SPECIFICATION.
Improved Means for Holding On Velocipede and other Brakes.
I, JOHN TIMOTHY BROWN, of 5^ St. Mary's Butts, Reading, in the County of
Berks. Whitesmith, 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 brake-holders for bicycles, tricycles, and like purposes.
It consists of a small rod at the lower end of which is a clip or clamp by which
it is attached to the brake-handle. At the upper end of the rod is a rack or series
of teeth, which slides through a small locking device, in which is a spring-catch
which engages with the teeth of the rack.
The locking device is clamped on to the handle-bar or otherwise attached thereto,
or to any convenient part of the machine.
To release the catch from the rack it is only necessary to press a small knob
which disengages the catch and allows the brake to resume its rest position. This
can also be effected by turning the rod halfway round so that it presents its smooth
side to the catch. In this case a swivel joint must be interposed between the rod
and the clip. If the first named action, the pressing of the knob, be resorted to;
it will be obvious that on the pressure being relaxed, the spring catch will again
engage with the rack. In order to secure a free action for the rod, which is
desirable in some cases, an angular slot and pin are introduced, so that on pressing
the knob as far as it will go, and giving it a turn sideways, it becomes locked, and
holds back the spring catch so that it cannot act on the rack.
At the other end of the locking device, which is by preference tubular, is inserted
a worm-screw with square head, the inner end of which can be screwed against the
spring-catch, so as to lock it against the rod. When thus locked the releasing knob
cannot act, nor can the rack be moved. This locking action serves to prevent
anyone using the machine in the absence of the owner.

page_text: I will now describe the invention with reference to the accompanying drawings
in which
Fig. 1 shows a view in perspective of my invention applied to the brake-handle
and guiding-handle of an ordinary safety bicycle.
Fig. 2 shows a nearly full size elevation of my invention detached.
Fig. 3 shows a sectional plan of the tube a with the two end knobs b and c.
Fig. 4 shows the knob b, the sliding catch d, and the worm-screw e detached from
the tube a.
Fig. 5 shows an enlarged section of the knob c, with the worm-screw e in
position.
a is the tubular case which contains the working parts. b is the knob which
disengages the sliding-catch d, as shewn in Fig. 4. It has the angular slot fcut
in its shank. This shank engages with the screw or rivet g shewn in Fig. 3. c is the
knob in which the head e¹ of the locking screw e works. c² is a fixed nut through
which the screw e passes. d is the sliding catch, the inner edge d¹ of which is made
sharp to engage with the rack i. d is the space through which the rack i slides.
is a small coiled-spring which bears at one end against the shank of the knob b
and at the other end against the small disk or bar . e is the worn screw which
Jocks the catch d against the rack i. This screw has a square head e¹ to fit the
key k, and a small collar e which forms a stop against the small recessed tube c'
inside the knob c. f is the angular slot in the shank of the knob b. g is a rivet or
screw which works in the slot f. i is the rack, at the lower end of which is
the clip l.
m is the clamp to fasten the tube a to the handle-bar.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1. A brake holder for cycles having three distinct actions, namely free, locked,
and automatic, as herein described and set forth.
2. In a brake-holder, the combination of a rack and clip, with a spring-catch and
locking device, as herein described and set forth.
3. In a rack and automatic catch-action the combination therewith of a spring-
action knob with slot and pin for stopping catch when necessary, or instead thereof,
of a rack cut on a round bar, which turns on a swivel joint, as herein described and
set forth.
