CHRIS ANDERSON, of Leeds, in the County of York IMPROVEMENTS IN THE
MEANS OR Apparatus Employed for WORKING RAILWAY BRAKES
"
My Invention is applicable for a continuous brake system, and is also so arranged
that each carriage may be provided with a separate apparatus, and may be either
caused to operate alone or in conjunction with any number of carriages
On one or both axles of each cannage is provided and fixed a worm which gears
into and causes the rotation of a woun wheel mounted on a shaft carried in suitable
bearings, by preference underneath the carnage On the same shaft is provided a
friction disc, which is kept up to the face of another disc attached to the worm
wheel by means of adjustable springs, whereby it is caused to revolve when the
worm wheel is in motion A loose rope, or chain pulley, or drum is provided on
the fiction disc shaft and attached to the discs, through which motion when
required is conveyed by a suitable arrangement of levers to the brake blocks In
connection with the friction disc aliangement is applied a clutch, which is by pre-
ference made frictional The clutch is always allowed to evolve when the carriage
is in motion By a convenient lever appliance it may be thrown in or out of gear
with the fictional disc, thus the rope, or chain pulley, or drum may be caused to
evolve, by which means the brake blocks are brought to bear at a suitable pressure
upon the wheel, the motion of which being thereby arrested and the carriage
brought to a standstill
Instead of the above arrangement of worm, and worm wheel, and clutch for
actuating the brakes I provide a friction wheel, the periphery of which is brought
to bear upon the periphery or tread of one of the running wheels, which when the
carriage is in motion causes the friction wheel to revolve On the friction wheel
shaft are provided a friction disc and chain pulley or drum, which are of a similar
construction to those herçın-before described in my first arrangement

page_text: When either of these arrangements is applied throughout a train to form a con-
tinuous brake system the connection is made between each apparatus by means of
ropes, rods, or then equivalents, which connection is extended to the guaid's van
and engine, so that the whole of the brakes may be operated simultaneously by either
the driver or guard

"IMPROVEMENTS IN THE
MEANS OR APPARATUS EMPLOYED FOR WORKING RAILWAY BRAKES
$9
My Invention consists in an arrangement of friction genuing and appliances for
working the saine for the purpose of applying and disengaging railway carriage or
other brakes in a continuous system, or separately
In carrying out my Invention I usually place a suitable disc or wheel, heroin-
after called the "friction wheel," in such a position with regard to the carriage
wheel or moving part to which the apparatus is to be applied that by a simple
novement caused and controlled by the person or persons manipulating the brakes
of a train or coach the said friction wheel can be put into contact with the said
cannage wheel or moving part so as to receive motion from the same for the purpose
of applying the brakes to the wheels of the carriage for retarding or stopping the
motion of the same, and also by reversing the same simple movement the friction
wheel" can be taken out of contact with the said carriage wheel or moving pait,
and the brakes be allowed to return to then inoperative position
"
In order that the brakes of a train or coach may be applied with any required
amount of force I provide a secondary friction surface on or in connection with the
"friction wheel," and place a fiction disc or suitable part, herein-after called the
secondary fiction disc," in contact with the said secondary fiction sui face m such
a manner that by means of spings or levers, or both combined, or other suitable
incans, under the control of the person or persons using the apparatus any requued
amount of pressure can be applied to the secondary fiction surfaces for the purposes
of obtaining the necessary power for the brakes and of allowing the "function wheel
to run until the motion of the train or caninge ceases without increasing the
pressure on the brake blocks or parts over what is considered to be necessary and
desiable for retarding or stopping the train or coach
For the purpose of regulating the pressure of the springs or other parts used on
the "secondary friction disc" and surface 1 usually provide a suitable piece of
mechanism attached to or in the train of the mechanism on parts which are pro-
vided for and used by the operator for the purpose of applying or placing in contact
of the "
friction wheel to the carriage wheel or moving part aforesaid in such a
manner that the brakes are applied by these means with a proportionate force to
that applied by the operator to the said mechanism or part
The apparatus is rendered automatic in its action in the case of a tiam parting
through the breaking of the couplings, &c by employing springs, or weights, o1
other stored power for the purpose of placing and holding the "triction wheel" in
contact with the cannage wheel or moving part aforesaid, and by holding the said
"fiiction wheel" out of contact with the said carriage wheel or moving parts by
means of the mechanism or parts provided for manipulation by the operator during
Buch time as the brakes are iequned to be inoperative
The power of the apparatus can be multiplied to what is necessary for the brake
purposes by means of chains, and wheels, and axles, levers, spur gear, piessuie
cylinders, and pumps, bellows, or any suitable and convenient means
In some cases 1 bring the fiction wheel in contact with the tail 01 1oad instead

and power for the brake purposes
In order to render the foregoing description of my Invention more clear I now
proceed to refer to the accompanying Sheet of Diawings, and to the letters and
figures marked thereon, in which,—
.
Figures 1 and 2 represent the side elevation and plan of a railway carriage fiame
fitted with the brake apparatus, and the letters refer to the parts as follows -a, the
friction wheel, b, b the secondary fiction surface and secondary friction disc, c, the
shaft on which the preceding parts are cured, d, the spring for placing and
holding the friction wheel in contact with the cantage whoel, e, a sliding bearing
allowing of a movement of the shaft c and parts carried by it, ff, a chain attached
to sliding bear.ng c and contral shaft g by means of a chain barrel h and fiction

wheel by means of a tortional strain and chain f, h, chain barrel for winding chain

Having now particularly ascertained and described the nature of my said Inven-
tion I wish it to be understood that I do not confine myself to the precise details
shewn and explained, as many modifications may be made without departing from
the main principles of the same, but what I claim to be novel and original, and
therefore secured to me by the herein-before recited Letters Patent are,-
Firstly The use of the fiction wheel combined with the secondary fiction
surface and the secondary friction disc, or other equivalents, and the method of
regulating the amount of power icquued by the biake by means of the apparatus
used for the purpose, or any modification of the same, substantially as shewn and
described
Secondly The use of a complete set of apparatus on each coach or vehicle which
can be used singly, as in shunting, or in a continuous system, substantially as
shewn and described

and seal, this Thirteenth day of July, in the year of our Lord One thousand
eight hundred and seventy-seven
