JOHN REUBEN TOZELAND 110 Lefevre Road North Bow, E. Engineer do hereby
declare the nature of my invention for AN AUTOMATIC BRAKE FOR PERAM-
BULATORS, BATH CHAIRS & ALL VEHICLES PROPELLED BY HAND and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
My Invention relates to an Automatic Brake for Three and Four Wheel
Perambulators Bath Chairs, and all Vehicles propelled by hand, and the Invention
consists of the construction, combination and arrangement of the Brake and rod for
working same from handle of Perambulator or other vehicle as hereafter described.
In order that the Invention may be more readily understood I have illustrated
the same by the accompanying drawings forming part of this specification.
Figure 1 shews an elevation of my brake attached to a Four wheel perambulator,
Figure 2 shews an elevation looking from the back of the said perambulator. The
same letters of reference on each figure indicate the same parts.
The Brake is constructed in the following manner:- -Attached to the spring of .
Perambulator is a light metal carriage A which carries the several parts of Brake.
B is a Friction wheel revolving in a metal frame C and having an hinged bearing
by à pin at D which is connected to A. The axle pin D¹ projects a little beyond
the outside of frame and is tapered towards end with a small hole in same. The
spring E attached to A keeps the Friction wheel over against front wheel of
Perambulator. The Brake block F is connected to Brake hanger which works on
a pin G fastened into A. The Brake hanger at H is connected to the tapered part
of axle pin D' by a piece of cat-gut or other suitable material.
The frame C of Friction Wheel B is connected by a wire, chain or other suitable
material to one arm of the metal crank I which is supported by a small bracket
from spring of Perambulator, attached to the second arm of this crank is a bent
rod J working on a pivot at K which is secured to back of Perambulator, the rod J
is carried up to the handle of Perambulator and terminates as shewn at L, the
termination being made of metal, wood or other suitable material.
Having now described the construction of the said Brake I will give a short
description of its action:-
By pressing L over to iron support of handle the crank I is turned which pulls
the Friction wheel away from front wheel of perambulator and takes off the brake,

page_text: The Brake is set in action immediately L is released by the tension spring E
forcing the Friction wheel B over to the Front wheel of perambulator, thus setting
it in motion. The friction wheel B revolving winds up on axle of Friction
wheel D¹ the connection between same and top of Brake hanger H, this draws the
Brake Block tight up against back wheel of perambulator, which stops the same.
The Brake now remains on until released by pressing L back to iron support of
handle.
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 combination and arrangement of the Friction wheel and Frame with
Tension spring, The Brake hanger and block and the mode of winding up the
latter from the Friction Wheel, with the carriage for this portion of the apparatus
substantially as herein shewn and described.
(2.) The combination and arrangement of the rod and crank at back of peram-
bulator for working the brake and the mode of connecting the same to the Friction
wheel substantially as herein shewn and described.
(3.) Such combination and arrangement of the several parts of my invention as
may be required to adapt my system to any perambulator, Bath Chair or any
Vehicle propelled by hand, the several parts being substantially as herein shewn
and described.
Dated this sixteenth day of November 1885.
