PROVISIONAL SPECIFICATION.
Improved Appliances or Means for Operating or Releasing the Brakes
of Cycles.
I, WILLIAM PARSLEY, of Kirkwood Road, Peckham, County of London, Cycle
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention relates to improved appliances or means for operating or releas-
ing the Brakes of Cycles.
For the purpose of my invention, I mount or secure a strap on the head of brake
rod, and by a clip which I secure on the handle bar stem or stalk I make a con-
nection with the strap, which is slotted for the purpose, by a bolt carrying a
creeper disc or cam, this having a handle or lever by which the creeper can be
operated for lifting, or for depressing the brake rod. The lower part of the strap
has a check or lip on which the cam can act, the centres of the bolt and the lip
being vertically arranged to ensure a direct thrust and a lock from any part of
the cam to which it may be turned.
The pressure of the brake can be exerted by the cam being turned to force the
rod down, the nip being in proportion to such rotation.
A helical spring can return the rod for removing the brake when the cam lever
is turned to release the pressure, but the spring can be utilised for pressure if the
cam be arranged for its removal.

COMPLETE SPECIFICATION.
Improved Appliances or Means for Operating or Releasing the Brakes
of Cycles.
I, WILLIAM PARSLEY, formerly of Kirkwood Road, but now of Clayton Road,
Peckham, County of London, Cycle Manufacturer, do hereby declare the nature
of my said 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 improved appliances or means for operating or releas-
ing the Brakes of Cycles.
My invention is represented on the annexed Drawings in which I show at
Figure 1 a part sectional elevation of my appliances with the brake off. Figure 2
a similar view with the brake on, and Figure 3 a side elevation of my appliances.

page_text: For the purpose of my invention I mount or secure a strap A on the head B of
brake rod and by a clip 1) which I secure on the handle bar stem or stalk E I
make a connection with the stran A which is slotted for the purpose at F, F, by a
bolt G carrying a creeper disc H or cam, this having a handle or one or more
levers II by which the creeper H, can be operated for lifting or for depressing the
brake rod C.
The lower part of the strap has a cheek J or lip on which the cam H can act,
the centres of the bolt and the lip J being vertically arranged to ensure a direct
thrust and a lock from, any part of the cam to which it may be turned.
The pressure of the brake K can be exerted on the tyre L by the cam H being
turned to force the rod C down, the nip being in proportion to such rotation.
A helical spring M can return the rod for removing the brake when the cam
lever I is turned to the vertical position to release the pressure, but the spring can
be utilized for pressure if the cam be arranged for its removal.
The levers I I¹ or one only can be of any length but I prefer that they be short
as represented, so that the Rider of the present day who while riding places his
hands near the stalk E may by his thumb have full command over the brake both
for reducing speed, for pulling up short, or for regulating pressure while descend-
ing hills, the thumb of the right hand putting the brake on and the left thumb
taking it off, both thumbs being constantly in touch with the levers I I¹ or to
button heads i thereon.
In the position of the levers I I¹ at Figure 1 the brake K is entirely off and
clear of touching the tyre L, the lip J being then at the shallowest part of the
cam H against which it is held by the action of the spring M, while at Figure 2
show the lever I so depressed as to lower the cam H on the lip J for the brake K
to slightly touch the tyre L without exerting pressure, but by a continuation of
such down push of the lever I a great pressure can be exerted.
I have shown, for the sake of clearness of the several parts, the levers I, I' at
most unusual positions, because in a normal position they would be about in line
with the handle bar N for easy manipulation by the thumbs of the Rider while he
grasps the handle bar with his fingers, but if it be desired to use the ordinary
brake lever, such as when holding the handles, I attach one, say to the button
head or to the hole in which by the removal of said button head is left vacant so
that the brake can be manipulated by the usual lever in the well known manner.
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. As a means for operating the brake of a Cycle, the combination of appliances
shewn on the annexed Drawings.
2. As a Cycle brake operating apparatus, the cam H, lip J connected by bolt G
to back plate, strap A slotted from F to Fanu affixed to head of brake rod C, as
described and shown.
3. The cam lever I for direct operation by the Rider or for attachment to an
ordinary brake lever for the purpose specified.
