page_text: I, HENRY JOSEPH MARIE PIE CAMUSAT DE RIANCEY, of 3, Place Daumesnil,
Paris, France, Manufacturer of Motor Vehicles, do hereby declare the nature of
this invention to be as follows:-
This invention relates to a brake for vehicle wheels having a special form of
wheel rim with pneumatic or rubber tyres. The brake is adapted to act upon each
wheel separately or upon both at once.
My invention is illustrated in the accompanying drawings in which Figure 1
represents a part elevation and Figure 2 a part underside plan of the brake applied
to a vehicle. Figure 3 is a cross section of the wheel rim, drawn to a larger
scale. Figures 4 and 5 shew the brake shoe separately.
The brake comprises:-
(1) A pair of metallic brake shoes A A (Figures 4 and 5) faced with a leather
strip B which is detachable in order that it may be replaced when worn. The
brake shoes are mounted on the ends of levers C C (Figures 1 and 2) so as to bear
upon the inside of the rims, the levers being pivoted at D D (Figure 2) and being
normally held out of action by springs E E;
(2) A wheel rim of special form (Figure 3) characterized by laterally projecting
flanges F against which the brake shoe bears;
(3) Two pedals G G (Figures 1 and 2) placed side by side and separately
connected to the brake levers by lever arms H H and connecting rods I I.
Either of the brakes may be operated by pressing on one or other of the pedals
with the foot or otherwise. The separate action of either of these two distinct
brakes is sufficient to reduce the speed of the vehicle on an ordinary descent
while by placing the foot upon both pedals both brakes are brought into operation
at once thus affording a powerful brake action for checking the motion upon
steep gradients or for stopping suddenly.
It will be seen from the foregoing that:-
(1) By means of the two pedal and brake levers, two independent brakes are
provided;
(2) The brake acts upon the maximum radius of the wheel without wearing.
the rubber tyre, the friction taking effect upon the rim;
(3) The brake may be applied for a long time without causing the heating
which is so objectionable with drum brakes.

page_text: It is to be understood that the forms, details, materials, and dimensions of
the brake may be varied without altering the nature of the invention. .

Improvements in and relating to Brakes for Road Vehicles.
I, HENRY JOSEPH MARIE PIE. CAMUSAT DE RIANCEY, of 3, Place Daumesnil,
Paris, France, Manufacturer of Motor Vehicles, 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 a brake for vehicle wheels adapted to act on a wheel
rim of special form having a pneumatic or rubber tyre, the brake being adapted
to act upon each wheel separately or upon both at once.
My invention is illustrated in the drawings accompanying my Provisional
Specification in which Figure 1 represents a part elevation and Figure 2 a part
underside plan of the brake applied to a vehicle. Figure 3 is a cross section of
the wheel rim, drawn to a larger scale. Figures 4 and 5 shew the brake shoe
separately.
The brake comprises:-
The
(1) A pair of metallic brake shoes A A (Figures 4 and 5) faced with a leather
strip B which is detachable in order that it may be replaced when worn.
brake shoes are mounted on the ends of levers C C (Figures 1 and 2) so as to bear
upon the inside of the rims the levers being pivoted at D D (Figure 2) and being
normally held out of action by springs E E;
(2) A wheel rim of special form (Figure 3) characterized by laterally projecting
flanges F against which the brake shoe bears;
(3) Two pedals G G (Figures 1 and 2) placed side by side and separately
connected to the brake levers by lever arms H H and connecting rods I I.
Either of the brakes may be operated by pressing on one or other of the pedals
with the foot or otherwise. The separate action of either of these two distinct
brakes is sufficient to reduce the speed of the vehicle on an ordinary descent
while by placing the foot upon both pedals both brakes are brought into operation
at once thus affording a powerful brake action for checking the motion upon
steep gradients or for stopping suddenly.
It will be seen from the foregoing that:-
(1) By means of the two pedal and brake levers two independent brakes are
provided:
(2) The brake acts upon the maximum radius of the wheel without wearing
the rubber tyre, the friction taking effect upon the rim;
(3) The brake may be applied for a long time without causing the heating
which is so objectionable with drum brakes.
It is to be understood that the forms, details, materials, and dimensions of
the brake may be varied without altering the nature of the invention.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
The herein described system of brake adapted to act on the rim of special form
of a pneumatic or rubber tyred wheel the brakes being adapted to act separately

page_text: or together on the two wheels and comprising two metallic brake shoes A faced with
leather B mounted on the ends of spring retracted levers C so as to be caused
by acting thereon through the pedals G and links I, to bear against the laterally
projecting flanges F of the wheel rims, substantially as specified.
