*Improvements in and relating to Brake Mechanism for Velocipedes.
I, HARRY PARSONS, of Ferndale, Wren Street, Coventry, in the County. of
Warwick, Engineer, do 'hereby declare the nature of this invention to be as
follows:-
This invention relates to an improved: method of mounting, or attaching : the
ordinary brake lever to the handle bar of a velocipede.
:
It comprises a special form of handle bar clip whereby a smooth and easy
working of the brake lever, is ensured without any tendency to rattle caused by
lateral play, moreover the clip, may be tightened up to any extent on the handle
bar without causing the brake lever to work stiffly or jam as at present happens
with clips, as now made, owing to the side: cheeks of the clips pressing into close
contact with the sides, of the brake, lever. Furthermore in. brake lever clips, as at
present constructed no provision is made.nor is it possible to take up the wear
caused by the brake lever pivotting or turning on the bolt or stud, whereas
according to the present invention, by simply. tightening the clip, the wear on the
brake lever is taken up in every direction.
This invention.consists essentially in forming the pivot on which the brake
lever turns of two or more. balls, one. or, more being arranged on each side of the
brake lever between it and the sides of the clip, each of the engaging surfaces being
suitably shaped to, receive-them.
A convenient method of constructing, a. clip according to this invention con-
sists in forming the clip in two, parts .so. shaped as to. be capable, of being, firmly
attached to the handle bar by means of, screw, studs or bolts, one on each side
thereof. Each part of the clip is furnished with a projecting portion adapted to
receive between them the brake lever. On each of the inner sides of these portions
diametrically opposite to each other is formed a recess or countersunk depression
adapted to form a cup or bearing for a ball. Each side of the brake lever is
similarly recessed or countersunk so that when the parts are assembled the brake
lever is supported or pivotted between the projecting portions of the clip, by
means of the balls one on each side.

I, HARRY PARSONS, of Ferndale, Wren Street, Coventry, in the County of
Warwick, 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 an improved method of pivotting brake and other
levers on the handle bars or other parts of velocipedes, and it comprises the
special form of clip bracket adapted to be clamped to the handle bar or other
part to which the lever is to be pivotted and the special form of pivot hereinafter
more particularly described whereby a smooth and easy working of the lever is
ensured without any tendency to rattle caused by lateral play, and whereby the
adjustment of the clip bracket on the part on which it is mounted can be effected
without causing the lever to work stiffly or jamb as now happens, with the clips
at present in use.
At present no provision is made for taking up the wear of pivotted parts the
consequence is that after use they get loose and rattle with the vibration of the
machine whereas according to the present invention the wear can be taken up in
a simple and ready manner.
In the accompanying drawing which illustrates this invention :-
Figure 1 is a view in side elevation-partly in section- and Figure 2 is a view
in front elevation.
In both views similar parts are marked with like letters of reference.
This invention consists essentially in pivotting the lever between the jaws of an
adjustable clip bracket by means of two ball centres.
The clip bracket A which is formed in two parts for convenience is shaped to
embrace the handle bar or other part X to which it is clamped by two screws B
and C the former passing through ears or lugs a a on one side of the clip and the
latter passing through ears or lugs a¹ a¹ on the other side thereof. The ears or
lugs a¹ a¹ are extended to form a jaw to receive the lever D which is pivotted to
said ears or lugs forming the jaw by means of a pair of balls E, E, fitting both
in countersunk holes or recesses d d in the sides of the lever D and in similar
holes or recesses a² a² in the inner faces of the ears or lugs a¹ a¹.
As a modification a hinge or other connection may be substituted for the
screw Bas a means of connecting the two parts of the clip bracket A together
at one side.
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) In velocipedes pivotting the brake or other levers to the brackets or parts
adapted to carry them by means of ball centres, as set forth.
(2) In velocipedes, pivotting brake and other levers to the frames or other parts
of the machines by means of clip brackets having ears or lugs on each side through
which transverse bolts or screws pass, the ears or lugs on one side being extended
to form a jaw in which the lever is pivotted by means of two balls engaging with
countersunk holes in the adjacent faces of the ears or lugs and lever, as and for
the purpose set forth.
(3) In a velocipede, the combination of a clip bracket A formed in two parts
fixed together at one side by a transverse screw B or its equivalent and having
at its opposite side ears or lugs a¹ a¹ forming a jaw and having countersunk holes

page_text: or recesses a² a² on their inner faces, of a transverse bolt C passing through the
ears or lugs a¹ a¹ between the countersunk holes or recesses a and the body part
of the clip bracket, of a lever D) having oppositely arranged countersunk holes
or recesses d, d, in its sides, and of balls E, E, adapted to engage with the counter-
sunk holes or recesses in the ears or lugs a¹ a¹ and in the lever D, as and for the
purpose set forth.
