PROVISIONAL SPECIFICATION.
An Improved Brake Treadle for Road Vehicles.
I, JOHN STEPHENS, Hawthorne Cottages, Hythe Road, Egham, Surrey,
do hereby declare the nature of this invention to be as follows:→
This invention consists of an improved brake treadle for road vehicles. In
carrying out my invention I provide a bracket or support which carries a toothed
quadrant which operates a rack which is connected to the brake block by any suit-
able and well-known means such as a rod or chain. This quadrant is connected
to one end of a bent pivoted lever by means of a link; the other end of this lever
being adapted to receive the foot pressure of the operator. A. spring is provided"
for bringing the brake back to its inoperative position after use.
Dated this 15th day of November 1897
I, JOHN STEPHENS, Hawthorne Cottages, Hythe Road, Egham, Surrey,
Blacksmith, 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 consists of an improved. brake treadle for road vehicles. In
carrying out my invention I provide a bracket or support which carries a toothed
quadrant which operates a rack which is connected to the brake block by any suit-
able and well-known means such as a rod or chain. This quadrant is connected
to one end of a bent pivoted lever by means of a link, the other end of this lever
being adapted to receive the foot pressure of the operator. A spring is provided
for bringing the brake back to its inoperative position after use.
Referring to the annexed drawings,
Figure 1, is a side elevation of my invention.
Figure 2 plan view of same.
a is a base plate or support which carries the bearing supports b & c & upon
which base plate or support a the rod d having the rack e upon same, slides. f is a
pinion wheel pivoted at 9 which gears in the teeth of the rack e and also with the
toothed quadrant piece h which is pivoted at i and having the prolongation j to which
the link is pivotally attached. This link is again pivotally attached to the
lever pivoted at m to the support c. n is a surface for receiving the pressure of

page_text: the foot upon the lever o which is pivoted at p to the support c and also at to the
lever 1.
r is a spring connected at s to the lever o & at g to the support b or other
suitable position for the purpose of bringing the mechanism to its initial or
inoperative position after having been used. It will be seen that when the end n
of the lever o is moved in the direction of the arrow 1 that the racked rod d will
be moved in the direction of the arrow 2 and to this rod is attached the connections
to the brake block which may be of any convenient and well-known arrangement
and the movement of the racked rod d'in the direction of the arrow 2 causes the
brake block to be brought into contact with the wheel of the vehicle which may
be of any suitable class.
:
The mechanism is attached to any suitable part of the vehicle through the
medium of the baseplate a or support by means of screws, bolts or the like.
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. In brakes for vehicles: the combined construction and arrangement of the
various parts substantially as and for the purpose set forth and illustrated herein."
2. In brakes for vehicles: a pivoted quadrant piece operating a pinion wheel
which gears with a sliding racked rod said quadrant piece being actuated by means.
of a link pivotally attached to a prolongation thereon, said link being attached
to a pivoted lever which is in turn operated by a pivoted lever, having at one end
a surface for the reception of the foot when applying the brake: a spring for the
purpose of bringing the mechanism to its initial position.
