Improvements in or relating to Railway Brakes.
I, WILLIAM SAMUEL LAYCOCK of Victoria Street Works, City of Sheffield
Manufacturer do hereby declare the nature of my invention to be as follows:-
My invention relates more particularly to the combination of an atmospheric
or of a vacuum brake, with the hand brake known as Morton's brake, described
in Letters Patent No. 14,495 of 1885, which can be applied from either side of
the wagon without disturbing the opposite lever.
This hand brake may be described briefly as a shaft extending from side to
side of the wagon, provided with arms to the right and left connected with the
brake blocks, and at each end with a hand lever working loosely upon the shaft,
but provided with a clutch which will engage with a corresponding clutch fixed
upon the shaft, so that when the lever on either side is pressed down the clutch on
that side will act upon the shaft and apply the brake.
The object of the invention, namely the combination of a hand brake with an
atmospheric pressure brake, or a vacuum brake is to enable wagons provided with
such a combination to be made up with the coaches of a passenger train without
destroying the continuity of the brake system; also that longer or heavier goods
trains can be run, than is at present safe, owing to the increased control such a
combination of brake power gives to the driver or guard.
I propose to fix upon the shaft, preferably somewhere near the centre thereof, a
clutch, one part fixed to the shaft and the other free to be turned upon the shaft
until it engages with the fixed part when if continued force is applied the shaft.
will be turned and the brake is applied.
The loose part of the clutch has an extension or arm which is connected directly
or indirectly with the piston rod of the atmospheric or vacuum cylinder. The
wagon so provided can form part of a continuous brake system.

COMPLETE SPECIFICATION.
Improvements in or relating to Railway Brakes.
I, WILLIAM SAMUEL LAYCOCK, of Victoria Street Works, City of Sheffield,
Manufacturer do hereby declare the nature of this invention and in what manner
the same has to be performed, to be particularly described and ascertained in and
by the following statement :-
My invention relates to the combination of an atmospheric, or of a vacuum
brake, with the hand lever brake known as Morton's brake, as described in the
Specification of Patent No. 14495 of 1885, which brake can be applied or put in
action from either side of the vehicle without disturbing the opposite lever.
The invention is illustrated in the annexed sheets of drawings, like letters of
reference indicate like parts in any of the figures.

page_text: Fig. 1, represents a side elevation of a railway wagon, giving a general view of
the combined apparatus.
Fig. 2, plan of wagon frame, showing the arrangement of the several parts.
Fig. 3, enlarged view of air cylinder, and clutch lever.
Fig. 4, underside of same.
Fig. 5, side view of the clutch.
Fig. 6, hanger bearing and double arm.
The hand brake consists of a shaft A, having a semi-rotary action in the
hanger-bearings B, and upon the shaft under the wagon frame W, are fixed two
double arms C, attached to which are the brake rods D, connected with the
suspended brake blocks E.
Outside the bearings B, upon each end of the shaft A, is firmly secured a
clutch F, and against the outer face of the clutch I place the hand lever G, which
is held in position upon the shaft by means of a cotter pin H, or its equivalent.
A similar arrangement is put upon the shaft on the opposite side of the wagon.
These levers are provided with a clutch I, which when the lever is pressed down,
will come in contact with the clutch F, and on a further application of force will
turn the shaft A, and force the brake blocks E, against the wheels, on both sides
of the wagon, but without moving the opposite lever.
The cylinder J, of either an atmospheric pressure, or of a vacuum brake, is
suspended by its trunnions or axes K, in the brackets L, attached to the underside
of the wagon frame W, and is connected with the main pipe by means of a flexible
tube M.
The piston rod N, is attached to a short arm O, which works loosely upon the
shaft A, between a collar P, and a fixed clutch Q with which the claw R, of the
arm O, engages when the piston rod is drawn into the cylinder J, (and is released
with the opposite movement,) putting on the brakes as before described.
This combination of apparatus for operating the brake blocks E, either by
hand, or by atmospheric pressure, or by vacuum, is to enable wagons or other
vehicles so provided, to be placed in a train of passenger carriages without
destroying the continuity of the air brake system, and also enables longer or
heavier trains to be run, (than would be safe under the present system,) by
reason of the increased control such a combination gives to the driver, or the
guard.
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:-
A combination of hand lever mechanism, with atmospheric or vacuum mechanism'
for the brakes of railway vehicles, constructed and arranged as hereinbefore
described and shown in the drawings.
