An Improved Hand Brake for Railway Wagons or Carriages.
HARRY RYLANCE HAIGH, 3, Arboretum Square, Derby, in the County of Derby,
Engineer, do hereby declare the nature of this invention to be as follows:-
An improved form and arrangement of hand brake for railway wagons or car-
riages, which may be operated from either side of the vehicle or the brake may
be applied from one side of the vehicle and released from the other side and is
of such arrangement and construction that it may be easily manipulated by the
shunters with one hand.
To accomplish this I fix a cross shaft below the wagon body having a short
lever or handle on each side of the wagon and I connect a lever on this shaft to
the present brake lever in such a manner that when the lever or handle is moved
to apply the brake the slack caused by the clearance of the brake blocks from the
wheels is rapidly taken up and the power for applying the brake increases as the
brake blocks approach the wheels. On this cross shaft I also fix a ratchet wheel
or segment having teeth conveniently arranged to engage with a pawl or pawls
for the purpose of holding the brake " on or off" as may be desired.

"
To provide for holding the brake "off" or holding it on and so that it may
be manipulated from either side of the wagon as may be desired I fix a second
cross shaft underneath the wagon body near to the first one this shaft also having
a handle on each side the wagon and I secure to this shaft a double pawl arranged
to engage with the teeth on the ratchet wheel or segment on the first mentioned
shaft so that when the handle on the end of the second shaft is turned in one
position one pawl or portion of the pawl holds the brake "off" and when the
handle is turned to another position the other pawl or portion of the pawl holds
the brake "
on."

HARRY RYLANCE HAIGH, 3, Arboretum Square, Derby, in the County of Derby,
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:-
An improved form and arrangement of hand brake for railway wagons or car-

on or
To accomplish this I fix a cross shaft below the wagon framing, having a short
lever or handle on each end of it, one of which levers I connect by means of a
link to the present brake lever in such a manner, that when the lever or handle
is moved to apply the brake, the clearance between the brake blocks and the
wheels is rapidly taken up, and the power for applying the brake increases as the
brake blocks approach the wheels. On this cross shaft I also fix a toothed or
ratchet segment, having notches or teeth conveniently arranged, so as to engage
" off" as may
with a pawl or pawls for the purpose of holding the brake
be desired.
To provide for the convenience of manufacture, the toothed segment and one
of the handles also the connecting lever may be made in one piece if desired.
For the purpose of holding the brake "off" or holding it "on" so that it may
he worked from either side of the wagon, I fix a cross rod underneath the wagon
body, near to the cross shaft before mentioned, this cross rod also having a
handle on each side the wagon, and I secure to this cross rod a double pawl so
arranged as to engage with the teeth on the toothed or ratchet segment on the
cross shaft, so that when the handle on the end of the cross rod is turned in one
position, one portion of the pawl holds the brake "off," and when the handle is
turned to another position, the other portion of the pawl holds the brake "
For convenience of manufacture I prefer the pawl and one of the handle made
in one piece.

Fig. 1 is a side elevation of a wagon, shewing my improved arrangement as
applied to the present existing form of brake gear.
Fig. 2 is an elevation, shewing the arrangement on the opposite side of the
wagon.
Fig. 3 is a plan of the wagon.
Fig. 4 shews the toothed or ratchet segment and handle, also the double pawl
and handle upon an enlarged scale.
The cross shaft a is fixed below the wagon framing by means of the brackets b, bl
this shaft having a short lever or handle, c¹ on each side of the wagon, lever d
having the connecting link c attached to the existing form of brake lever f, the
toothed or ratchet segment with lever d and handle e Figs. 1 and 4 being
shewn in one piece.
The cross rod h is fixed near to the cross shaft a, and also has a handle on each
side the wagon i, i¹, on one end of cross rod h is a double pawl or pawls kk¹, so
that when handle i is turned to the position M Fig. 4 pawl k will engage with
a notch in g and hold the brake "off," and when the handle i is turned to the
position N the pawl will engage with one of the teeth in g and hold the
brake "on."
Having now particularly described, and ascertained, the nature, form, arrange-
ment, and purpose, of my said invention, and in what manner the same is to be
performed, I declare that what I claim is :-
-
1. In connection with either-side brakes for railway wagons and carriages, a
toothed or ratchet segment, of the shape or form shewn in Fig. 4 on the drawing,
fixed on the cross shaft, to which toothed or ratchet segment is attached the handle 5
for working the long brake lever, substantially as described, and for the purpose
set forth.
"
2. A pawl or pawls, of the shape and form with handle attached, as shewn
in Fig. 4 on the cross rod, for holding the brake " on or off" substantially
as described.

page_text: 3. The combination of Claims 1 and 2 for the toothed or ratchet segment, with
the pawl or pawls of the shape and form shewn, working together for the purpose
set forth, and substantially as described in the specification, and shewn in the
drawing in Figs. 1, 3, and 4.
