COMPLETE SPECIFICATION.
Improvements in Brakes for Railway Wagons.
I, EDWARD WARNER, 73, Billing Road, Northampton, Engineer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
My invention consists in taking parts of two other brakes and so combining
them together as to make them work in such a way that by this my new
arrangement a much more simple and reliable and workable hand brake for
railway wagons is produced.
I first combine the rack A attached to the hand lever B shown in Fig. 1 of
my Patent Specification No. 14752 of 1898, with the cross rod e having a crank
or lever e at each end, as shown in drawings sheet 2 of Patent Specification No.
3789 of 1895, also the shackle or link f which connects the radial arm of the
crank of the cross rod e with the hand lever a of the brake shown on Sheet 1,
of the last named specification.
With the above I combine a pawl and handle
of the particular design shown in the drawing accompanying this specification
the object of this pawl being to engage with the rack and thus suspend or hold
the brake lever up when the brake is off or to hold it down when the brake is
applied for stopping or for holding the wagon.
In the accompanying drawing Fig. 1 shows a side elevation of a wagon with
the combination brake attached, Fig. 2 the reverse side of the wagon showing
handles for working the brake from the off side of the wagon, Fig. 3 a plan,
and Fig. 4 the rack A, the lever B, the crank e, the link f, and the pawl C upon
an enlarged scale.
A is the rack on the end of the brake lever.
B the lever for applying the brake.
C the pawl with handle 2.
e the crank on the end of cross rod e.
e the cross rod connected with the crank e.
f the connecting link or shackle.
H the cross rod connected with the pawl.
The following is the manner in which this brake, according to my arrange-
ment will be worked. The operator will first turn over the pawl handle 2, in
the direction of the arrow 7, when the rack A and the brake lever B will fall
and apply the brake to the wheels, the point of the pawl will then engage with
the notches in the rack A and keep the brake lever tight down until released,
which is done by placing the pawl handle 2, back again to its former position,
in which position another point of the pawl engages with the notches in the rack
and suspends or holds the brake lever up.
By means of the cross shaft e, and the crank e, and link f, together with the
handle 2, shown in Fig. 2, the brake lever B can be worked up and down and
the bral applied and taken off as well from the off side of the wagon as it can
be on the near side. The handle J with the cross rod H works the pawl from
the off side of the wagon in the same manner as it is worked on the near side.

page_text: When the brake is off the wheels,, the rack A and the hand lever B and the
pawl C and the handle 2 are in the position shown in Fig. 1, and when the brake
is applied those said parts are in the position shown in Fig. 4.
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 combination of rack A and the lever B in Patent Specification No. 14752
of 1898 with the crank e, the link f and the cross rod e in Patent Specification
No. 3739 of 1895 with the pawl C and handle 2 arranged together as shown in
the drawing and substantially as described in the specification.
Dated this 12th day of August 1899.
EDWARD WARNER.
