I, JOHN HIPWOOD FITTER, of 8, 9 and 15 Grand Avenue, Leadenhall Market,
London E.C. Meat Salesman do hereby declare the nature of my said invention to be
as follows:
The object of my invention is to effect improvements in brakes for road vehicles,
whereby the action of the brake blocks.or pads upon opposite wheels at each end of
an axle are equalised.
According to my invention, I fit two separate levers to the underside of the vehicle,
or to any convenient part of the frame, and fit the brake blocks to the short arms of
the levers. Springs are fitted to the long arms of these levers, which draw the brake
blocks away from contact with the wheels. A grooved pulley is fitted to the long arm
of each lever, and a third pulley is fitted to the rope or bar connected to the foot lever,
or its equivalent. The two ends of a wire or other rope or chain are made fast to
the underside of the vehicle, or to the frame of the vehicle, and looped to the tiree
pulleys.
The effect of this arrangement is such that, on the depression of the foot lever or
its equivalent, the two levers are simultaneously operated, and both brake blocks
or pads are placed in contact with the wheels with equal force, notwitlistanding any
inequality in the pads occasioned by wear; the action of the pulleys and rope or chain
compensating therefor, and rendering the brakes self-adjusting.
In applying my invention to light vehicles I sometimes dispense with the pulleys
on the levers, and attach the rope or chain to the levers direct, looping it round the
pulley attached to the rope or bar in connection with the foot lever, or its
equivalent.
I, JOHN HIPWOOD FITTER, of. 8, 9, and 15 Grand Avenue, Leadenhall Market
London E.C. Meat Salesman, do hereby declare the nature of my said invention and in
what mauner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
The object of my invention is to effect improvements in brakes for road vehicies

page_text: whereby the action of the brake blocks or pads upon opposite wheels, at each end of
an axle, are equalised.
And in order that my said invention may be particularly described and ascertained
reference is hereby made to the accompanying drawing illustrating the application of
my invention to an ordinary four-wheeled van.
1 is the underside of the body of the van. 2, 2,are the front wheels and 3, 3, the
hind wlieels. 4, 4, are two horizontal levers pivoted to the body of the van at 5, 5.
The short ends of the levers are fitted with brake blocks at 6, 6. 7, 7, are two springs
in tension bolted at 8, 8, to the body of the van, the other ends of the spring 7 are
attached to the outer ends of the long arms of the levers, the function of the springs
being to disengage the brake blocks from the wheels. The long arms of the levers
are fitted with grooved pulleys 9, 9. 10 is a grooved pulley attached to a bar or rope
or chain 15 which connected with the foot or hand lever in any suitable manner,
under the control of the driver. If rope or chain is used with the pulley 10 suitable
guides are provided to ensure the proper motion of the pulley. 11 is a wire or other
rope or chain rove round the pulleys 9 and 10, the two ends of the rope being fastenedi
to screwed rods 12 passing through staples 14 attached to the body of the van
and regulated by nuts 13, whereby the tension of the rope or chain secured and
regulated.
"
The effect of this arrangement is such that, on the depression of the foot lever
or its equivalent, the two levers are simultaneously operated, and both brake
blocks or pads are placed in contact with the wheels with equal force, notwithstanding
any inoquality in the pads occasioned by wear, the action of the pulleys and rope or
chain compensating therefor, and reducing the brakes self adjusting.
In applying my invention to light vehicles I sometimes dispense with the pulleys
on the levers, and attach the rope or chain to the levers direct, looping it round the
pulley 10 in connection with the foot lever or its equivalent.
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. The improved construction and arrangement of brakes and appliances in
connection therewith, substantially as and for the purposes described and illustrated
by the drawing.
2. In brakes for road vehicles, the combination of two double-ended levers fitted with
brake blocks 6; disengaging springs 7, and grooved pulley 9, actuated by means of an
ordinary foot lever or its equivalent, in connection with a bar 15 carrying a grooved
pulley 10, and adjustable wire, rope or chain 11, substantially as hereinbefore described
and illustrated by the drawing.
3. In brakes for road vehicles the combination of two double-ended levers 4 fitted
with brake blocks 6, and disengaging springs 7, actuated by an ordinary foot lever
or its equivalent, in connection with a bar rope or chain 15 carrying a grooved
pulley 10, and a wire rope or chain 11 rove round the pulley 10 and having its two
ends attached directly to the long arms of the levers 4, substantially as hereinbefore
described and illustrated by the drawings.
