I, GEORGE WESTON, of 65 Charles Street, Sheffield, in the County of York,
Machinist, do hereby declare the nature of my invention for AN IMPROVED BRAKE
FOR RAILWAY CARRIAGES, TRAMWAY CARS AND LIKE VEHICLES, to be as follows:-
I make use of sufficiently strong springs to pull tight by means of rods and
levers the usual brake blocks, or by preference straps or bands fitting loosely around
drums or pulleys fixed fast upon the wheel axles of the carriages, I also, within the
framing of the carriages fix cross shafts journalled to revolve, and upon said shafts
arms or levers are fixed fast. To one of said arms a pull rod is connected, the
other end of said rod is joined to the draw bar of the carriage so that the motion of
the draw bar when it is pulled draws the connecting rod and actuates the lever
and cross shaft in the reverse direction to the pull of the before mentioned springs
which are also connected to a lever which is fixed upon the cross revolving shaft,
The draw bar power exceeding the pull of the springs releases the brakes from
acting upon the wheels of the carriages. Brake-block rods or strap rods are con-
nected to levers fixed upon said cross shaft. To cause each draw bar to act simul-
taneously a rod from each is connected to a reversing lever so that when either is
pulled the other is pushed to act upon the brakes of each pair of wheels.
To suspend the action of the brakes for shunting, I purpose using a hand wheel
fixed upon a threaded spindle and screwed nut, with lever connection betwixt the
nut and draw bar.

I GEORGE WESTON late of 65, Charles Street Sheffield in the County of York,
but now of 35 Harwood Street in Sheffield aforesaid Machinist 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 :-
The principle involved herein, consists in making use of the power the Engine
exerts to draw the Carriages, to give release to the power applied to the Brakes,
also having the Brakes constantly ready to act, and I effect or accomplish the
same in the following manner.
I make use of sufficiently strong Springs, to pull tight by means of rods, and
levers, the usual Brake Blocks, or, by preference, Straps or Bands fitting loosely
around drums or pulleys fixed fast upon the wheel axles of the Carriages. I also,
within the framing of the Carriages, fix cross shafts journaled so as to revolve, and
upon said Shafts, arms or levers are fixed fast to one of said Arms with which is
connected a pull rod, the other end of said Rod being joined to the draw-bar of the
Carriage.
The motion, therefore, of the draw bar when it is pulled, draws the connecting
rod and actuates the lever and cross shaft in the reverse direction to the pull of the
before mentioned Springs, which are also connected to a lever which is fixed upon
the cross shaft, the draw bar power exceeding the pull of the Springs and so releases
the action.
To cause each draw bar to act simultaneously, a rod from each is connected to a
reversing lever, so that when either is pulled, the other is pushed so as to act upon
the Brakes of each pair of wheels.
To suspend the action of the Brakes for shunting, I use a hand wheel fixed upon
a threaded spindle, and screwed Nut with lever connection between the Nut and
the draw bar.
The accompanying Drawing illustrates the application of my Invention, being a
side elevation, shewing the general Construction and working of same.
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
The application of a Spring, actuating a Lever, to draw tight a friction strap
round a friction pulley, whereby, the Brake is constantly applied, except when the
draw bar is in action.
