PROVISIONAL SPECIFICATION.
Improvements in Hand Brakes for Railway Wagons and like
Vehicles.
I, HENRY HYAM RIDER, of Elmtree House, Rotherham, in the County of York,
Engineer, do hereby declare the nature of my invention to be as follows:-
My invention is for an improved arrangement of hand brake mechanism for
railway wagons and like vehicles, the operating levers being placed at diagonally
opposite corners, that is, in the same relative position upon each side of the
vehicle.
The brake is put into action by simply forcing down one of the hand levers
in the usual way, and a pin, or rack and pawl may be used to secure it in such
position.
In carrying out my invention, I provide a transversely fixed rocking shaft,
upon which are arranged two duplicate sets of double brake blocks with suit-
able push rods, levers and the like of the usual type, and upon each end of the
shaft I fix a hand lever; these levers point in opposite directions and are pro-
tected by the usual guards.
"
When the hand levers are in their central position in the guard, the brakes
are off," and clear of the wheels, and to apply them it is only necessary to
press down one of the said hand levers on either side of the vehicle with sufficient
force.
To release the brake from the opposite side of the vehicle, the lever upon such
opposite side is first slightly raised, which sets the retainer at liberty, it is then
depressed to the central position before mentioned in which all the brake blocks
are clear from the wheels.
Any mechanical device may be employed to hold the balanced levers in this
position.

Improvements in Hand Brakes for Railway Wagons and like
Vehicles.
I, HENRY HYAM RIDER, of Elmtree House, Rotherham, in the County of York,
Engineer, 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:-
My invention relates to an improved arrangement of hand-brake mechanism

page_text: for railway wagons and like vehicles, for the purpose of applying and releasing
the brake from either side of the wagon, having the operating levers placed at
diagonally opposite corners, that is in the same. relative position upon each side
of the vehicle, that is to say, the handles of both the operating levers may be
right handed or left handed but the former preferred.
The brake is put into action by simply forcing down one of the hand levers in
the usual way, and a pin or pawl and a rack may be used to secure it in such
position.
The annexed drawings clearly illustrate the method of application of my
improved apparatus, similar letters of reference indicate similar parts in any
of the figures.
Fig. 1, is an elevation of a railway wagon frame showing the brake with two
different means of securing the levers.
Fig. 2, end views of each plan of securing the levers.
Fig. 3, plan of wagon frame and brake mechanism.
In carrying my invention into practice as shown in the annexed sheet of draw-
ings, I provide a central transverse rocking shaft A, carried in suitable bearings
such as B, affixed to the wagon frame C; and upon this shaft I secure two short
double-end arms D, to which are attached suitable push rods E, and brake
blocks F.
At each end of the rocking shaft A, I secure a hand lever G and G2, extending
in opposite directions as shown, their free ends restricted in lateral movement
by guards H, within which the levers can travel vertically up and down.
It will therefore be clearly seen that when one lever is pressed down the other
lever will be raised, and vice versa; and that which ever of the said levers is
pressed down far enough, two of the brake blocks F will be applied, one to each
pair of wheels, and the other two brake blocks F will be withdrawn, and the
opposite lever raised.
The push rods may be so connected to the double-ended arms D, and the brake
blocks F, that in the plan (Fig. 3), the two of the four brake blocks F, which are
being applied by the downward motion of one of the levers G, may be those
blocks which are diagonally opposite each other, or if preferred those two blocks
which are on the same side of the wagon.
The edges of the guard H, are serrated upon the convex side preferably, and
upon the hand lever I pinjoint a tumbler pawl I, weighted at J. or otherwise
constructed to automatically move out of gear with the teeth of the rack, when
not restrained by frictional contact; or instead of a pivotted tumbler pawl I,
I may use a pin K, preferably chained to a lever.
When it is desired to apply the brake, one of the hand levers is pressed down
with sufficient force and the tumbler pawl or the pin as the case may be, is made
to engage with the rack above the lever and thus keep the brake applied.
To release the brake from the opposite side of the vehicle to that on which it
has been secured in the "on" position, the lever on such opposite side is first
slightly raised which depresses the other or engaged lever and frees the pawl
or pin, if a pawl, the weight J, disengages it from the teeth of the rack, and if a
pin it drops out of the teeth by gravitation, the attendant then depresses the
hand lever to its central or horizontal position which clears all the brake blocks
from the wheels.
Any mechanical device may be used to secure the balanced levers in this
central position if found desirable, such as frictional contact.
. 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 improved construction of hand brake mechanism for use upon both
sides of railway wagons, or the like, constructed and operating as hereinbefore
described and shown.

page_text: 2-An arrangement of hand lever mechanism in which one lever balances the
weight of the other, and so that the handles are in the same relative position on
each side of the wagon, and each capable of putting on the brake or releasing the
brake from either side of the vehicle substantially as hereinbefore described and
set forth.
3--An arrangement of hand brake mechanism for railway vehicles consisting of
a transverse central rocking shaft A, carried in bearings B, and fitted with
arms 1), push rods E, and brake blocks F, operated by levers G and G², extending
from the shaft A, in opposite directions; contact being maintained by means of
a rack guard H, and a co-acting pawl I, or its equivalent as herein before described,
with reference to the drawings.
4-In hand brake mechanism for railway vehicles, the use of one or more brake
blocks in duplicate, so arranged that when one or more are applied one or more
(as the case may be) are withdrawn, all being actuated and moving simultaneously
by the operation of either of the hand levers, as herein before described.
