Improvements in or relating to Brakes for Velocipedes and the like.
I, JOSEPH HOLLIS, 27, Bath Street, Ilkeston, Derbyshire, Jeweller, do hereby
declare the nature of this invention to be as follows:-
This invention relates to improvements in brakes for velocipedes and the like in
which the mechanism for operating the brake is carried in a hollow handle bar.
In carrying out my invention I employ a loose sleeve or piece which slides in
the hollow handle bar being connected to the brake rod or tube by means of pivoted
bent levers or cranks connected together by wires or the like so that by operating
the loose sleeve or piece the brake is applied to or removed from the wheel as
required. The sliding sleeve or piece is operated by a pivoted lever which is
pivoted at or about the handle or grip. The brake rod or tube is adjustable and
the connecting parts are adjustably secured to the loose sleeve or piece by means of
a screw and nut or such like.
By the use of the pivoted bent levers or cranks the rubbing of the connecting
wire or the like upon the interior of the hollow handle bar is avoided.

Improvements in or relating to Brakes for Velocipedes and the like.
I, JOSEPH HOLLIS, 27, Bath Street, Ilkeston, Derbyshire, Jeweller, 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 brakes for velocipedes and the like in
which the mechanism for operating the brake is carried in a hollow handle bar.
In carrying out my invention I employ a loose sleeve or piece which slides in
the hollow handle bar being connected to the brake rod or tube by means of pivoted

the loose sleeve or piece the brake is applied to or removed from the wheel as
required. The sliding sleeve or piece is operated by a pivoted lever which is
pivoted at or about the handle or grip.. The brake rod or tube is adjustable and
the connecting parts are adjustably secured to the loose sleeve or piece by means of
a screw and nut or such like.
By the use of the pivoted bent levers or cranks the rubbing of the connecting
wire or the like upon the interior of the hollow handle bar is avoided.

Referring to Figures 1, 2, and 3, a is a loose sliding piece which slides in the
handle bar band is connected to the rode through the medium of the nut d, said
rod passing through the end of the sliding piece a. The rod c is pivotally attached
to the bell crank lever e which is in turn pivotally fixed at f to a support on the
handle bar. Pivotally attached to this bell crank lever e is a rod g provided with
a screw thread hand which engages in the piece i which operates the rod i carrying
the brake surface k which in this case is à rotatable roller. k is a spring which
tends to maintain the brake in its inoperative position. The tube in which the
spring and rod j are carried is attached to the bottom of the tube n by means of
a suitable joint such as the bayonet joint as shewn in Figure 4. the whole being
enclosed in the steering tube or stem ¹. The rod jis operated by the piece i through
the medium of the pin m which is carried in the rod j. By this arrangement it
will be seen that the brake surface may be disconnected from the mechanism by
the removal of the tube 7, thus facilitating the adjustment of the distance between
the ends of the rods h and j which is done by rotating the piece i in the required
direction. The bell crank lever is so shaped as to prevent the rods e and g coming
into contact with the handle bar or tube a when the brake is being operated. The
louse sleeve is operated by the hand lever o which passes through a slot in the
hollow handle bar and engages in the recess in the loose sleeve or sliding piece
and by moving the lever o in the direction of the arrow 1 the loose sleeve or sliding
piece a will be moved in the direction of the arrow 2 which will cause the brake
surface k to be depressed and bear upon the wheel.
a
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. The combined construction and arrangement of the various parts substantially
as described and illustrated herein and for the purpose set forth.
2. In brakes for bicycles in combination with the hollow handle bar: a loose
sleeve or sliding piece sliding in the interior of said handle bar and operated by a
hand lever projecting through said handle bar; said loose sleeve or sliding piece
being connected to a bell crank lever pivotally supported in the handle bar and
which bell crank lever operates a rod having a screw thread engaging in an adjust-
able piece or collar, said adjustable piece or collar operating the brake surface
through the medium of a rod which is caused to return to its initial position by
means of a spring, said rod and spring being enclosed in a movable tube which may
be secured by any suitable form of joint such as a bayonet joint for the purpose of
facilitating the adjustment of the parts.
