PROVISIONAL SPECIFICATION.
An Adjustable Attachment for Controlling the Brakes of Bicycles,
Tricycles, and the like.
ERNEST CHARLES PEARCY Clifton Villa London Road Sittingbourne, Kent
Draughtsman do hereby declare the nature of this invention to be as follows:-
My invention relates to an adjustable attachment which can be adapted to any
kind of bicycle, tricycle or the like & has for its object, to control the brake while
in use to any desired pressure and in such a manner that the hand, instead of
holding the brake on while descending a hill, is left entirely free for the purpose
of steering etc. It is also applicable to bicycles, tricycles or the like for locking
the wheel, thus enabling them to be left on an incline or in any other position. In
carrying out my invention I provide an adjustable clip which is attached to the
handle bar by any suitable means. On this clip I provide a projecting piece
through which a rod passes that is attached to the ordinary brake lever. On this
rod indentations are formed, into which a small catch is made to engage. Thus
when the brake is used in the ordinary way the rod passes through the projecting
part of the clip on the handle bar & is there secured by a catch and so held in any
position until released.

COMPLETE SPECIFICATION.
An Adjustable Attachment for Controlling the Brakes of Bicycles,
Tricycles, and the like.
I ERNEST CHARLES Pearcy of Clifton Villa, London Road Sittingbourne in
the County of Kent Draughtsman 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:—
My invention relates to an adjustable attachment which can be adapted to any
kind of bicycle, tricycle or the like and has for its object to control the brake while
in use to any desired pressure, in such a manner that the hand instead of holding
the brake on while descending a hill is left entirely free for the purpose of steering
or the like. It is also applicable to bicycles, tricycles or the like for locking the
wheel, thus enabling them to be left on an incline or in any other position.
And in order that my invention may be thoroughly understood, I now proceed
to describe the accompanying drawing thereof reference being had to letters and
figures marked thereon.
Fig. 1, is a side elevation of the apparatus attached to a machine with the brake
not in gear.
Fig. 2. is a front elevation of Fig. 1.

page_text: Fig. 8 is a view of Fig. 1, with an alternate form of teeth and catch.
Fig. 9, is an alternate form of Fig. 2.
Fig. 10, is an alternate form of Fig. 4.
Fig. 11, is an alternate form of Fig. 5.
Fig. 12, is an alternate form of Fig. 3.
Parts of the figures are broken off for convenience.
In carrying out my invention I provide an adjustable clip c which is attached to
the handle bar a, by any suitable means. On this clip c I provide a projecting
piece d, through which a rod g passes that is attached to the ordinary brake
lever b, on this rod g indentations or teeth h, are formed into which a small catch i.
is made to engage, thus, when the brake is used in the ordinary way the rod
passes through the projecting part d. of the clip c on the handle bar a, and is there
secured by a catch i, and so held in any position until released.
a is the handle bar, brake lever, c. adjustable clip fixed over handle bar a,
d projection on clip c, e adjustable clip for attaching to brake lever, g rod, working
loosely on and attached to the clipe by the movable screw m and passes up through
the projecting part d of clip c, when the brake lever bis worked in the ordinary
way and has indentations or teeth formed at h. h is the teeth, i is a movable catch
working through the projecting piece d, against the spring k, and is drawn in and
out of action by the so shaped cam 1, which is pivotted at the end of catch i. The
other end of the catch is shaped the same as the teeth h. on rod
I is the cam,
when the attachment is required for use the cam lis turned round in position shewn
at Fig. 4, which lets the catch go tightly up against the rod g. as shewn at Fig. 2,
and when the brake is raised the rod passes up by the catch, which, through the
spring forcing it engages itself into the teeth on rod as shewn at Fig. 3, and so
holds it there until released by pulling the cam into position as at Fig. 5, which
draws back the catch and allows the brake lever to fall. This may also be made
so that the catch and spring is enclosed in all round and hidden from sight.
g.
Fig. 7 shews an alternate form of attaching the toothed rod to the brake lever.
is the rod working loosely on the bolt f which passes through the brake lever b
and is secured to the same by the two screwed nuts n.
g
The object of the invention is to control the brakes of cycles both when in and
out of use, which in the ordinary way the hand has to do, and by its use it leaves
the hand entirely free for steering or the like.
The apparatus herin before described can be used in putting any desired pressure
on to the wheel and holding it in that position with the object of steadying the
machine down an incline.
It can be easily attached to any machine and is fixed on the handle bar of the
machine whichever side the brake lever is and close to the handle so as to be
easily worked by the finger.
The invention although if fixed to a machine, need not necessarily be always in
action when the brake lever is raised but by keeping the catch i out of engagement
the brake can be pulled up and down in the ordinary way and not be affected, but
by letting go the catch i it is then in use.
It is also applicable for locking the wheels of machines, as it can be applied so
that the wheel is held tight and immovable, this being an advantage in leaving a
machine unguarded or in the case of a tricycle it could be left in any position on
an incline.
I do not confine myself to any particular form of carrying out my invention so
long as the method is kept to, as in the accompanying drawing the apparatus is
shewn in various ways, namely, one in which it is self acting and the other has to
be actuated by the finger.

page_text: 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 an adjustable attachment for controlling brakes of bicycles, tricycles and
the like, the combination of the apparatus, substantially as herein described and.
according to the accompanying drawings.
2. In an adjustable attachment for controlling brakes of bicycles, tricycles and
the like, the combination of the brake lever b, adjustable clip c, projection on
clip d, adjustable clip e, bolt f to brake lever, rod 9, teeth h, movable catch i, and
cam 1, substantially as herein described and according to Figs. 1. 2. 3. 4. 5 and 6,
of the accompanying drawings.
3. In an adjustable attachment for controlling brakes of bicycles, tricycles and
the like, the combination of the brake lever b, adjustable clip c, projection on
clip d, adjustable clip e, bolt f to brake lever, rod 9, teeth h and movable catch i,
substantially as herein described and according to Figs. 7. 8. 9. 10. 11 and 12, of
the accompanying drawings.
Dated this 28th day of February 1895.
