Manager, do hereby declare the nature of this invention to be as follows.-
This invention relates more particularly to the brakes of railway wagons, and
has for its object, the prevention of the dangerous practice of railway servants
having ever to cross the railway lines for the purpose of getting to the brake in
order to apply or release it
In my invention the ordinary 1ocking shaft hangers, push rods, brake blocks,
and block hangers are used, but the brake shaft is made to extend the width
of the wagon, and 18 carried by means of the ordinary vee hangers fixed on each
solebar.
The ends of this cross-shaft are made square, or of a suitable shape to receive
two long levers, one on each end of the shaft, which take the place of the long
hand levers generally used for operating the brake Each of these long levers
I make in two parts, which parts are jointed or connected together about midway
in their total length, in such a way that when either of the levers are litted,
or pressed down, the lever remains rigid in its length, but when pulled outwards
or pushed inwards, the handle end of the lever is free to move.
The portion
of the lever fixed on the shaft, extends up to the joint, or may be a little
beyond; the other, or handle, portion of the lever, is extended from the handle
end to a little distance past the joint, and behind the end of the lever fixed on
shaft.
From one end of the handle portion of the long lever, and at an equal
distance from the joint on the same lever, I fit rods, which connect together the
two hand levers on the opposite sides of the wagon. These two rods extend
across the underside of the wagon, and are placed diagonally with each other.
One end of each rod is attached to one hand lever at one side of the joint,
whilst the other end of each rod 18 connected to the opposite lever at the other
side of the joint.
By this means when either of the hand levers are lifted out of the ordinary
lever rest, and pulled outwards, so as to be free to travel and be pressed down
the lever guide for applying the brake, the same movement correspondingly
and simultaneously takes place with the hand lever on the other side of the
wagon and which is not directly actuated.
The brake lever guides with toothed racks are used, and on the hand levers
suitable projections are made and conveniently placed in order to engage with
the toothed rack for holding down the brake.

WALTER GATWOOD, 128, Ashton Old Road, Openshaw, Manchester, Works
Manager, 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.
This invention relates more particularly to the brakes of railway wagons, and 5
has for its object, the prevention of the dangerous practice of railway servants
having ever to cross the railway lines for the purpose of getting to the brake in
order to apply or release it.
In my invention the ordinary rocking shaft hangers, push rods, brake blocks,
and block hangers are used, but the brake shaft is made to extend the width
of the wagon, and 18 called by means of the ordinary vee hangers fixed on each
solebar.
The ends of this cross shatt are made square, or of a suitable shape to receive
two long levers, one on each end of the shaft, which take the place of the long
hand levers generally used for operating the brake Each of these long levers
I make in two parts, which parts are jointed or connected together about midway
in their total length, in such a way that when either of the levels are lifted,
or pressed down, the lever remains rigid in its length, but when pulled outwards
or pushed inwards, the handle end of the lever is free to move. The portion
of the lover fixed on the shaft, extends up to the joint, or may be a little
beyond; the other, or handle, portion of the lever, is extended from the handle
end to a little distance past the joint, and behind the end of the lever fixed on
shaft.
From one end of the handle portion of the long lever, and at an equal
distance from the joint on the same lever, I fit 1ods, which connect together the
two hand levers on the opposite sides of the wagon These two rods extend
across the underside of the wagon, and are placed diagonally with each other.
One end of each rod 18 attached to one hand lever at one side of the joint,
whilst the other end of each 10d 18 connected to the opposite lever at the other
side of the joint
By this means when either of the hand levers are lifted out of the ordinary
lever rest, and pulled outwards, so as to be free to travel and be pressed down
the lever guide for applying the biake, the same movement correspondingly
and simultaneously takes place with the hand lever on the other side of the
wagon, and which is not directly actuated.
The brake level guides with toothed racks are used, and on the hand levers
suitable projections are made and conveniently placed in order to engage with
the toothed racks for holding down the brake
In order that my said invention may be more clearly understood, it is illustrated
on the two accompanying sheets of explanatory drawings, which show the means
I prefer to adopt in carrying it out in practice The drawings are marked with
figures and letters of reference, corresponding with those given in the following
description, like references indicating the same parts in all the figures.
Figure 1 on Sheet 1 of the drawings, is an elevation of a wagon brake, accord-
ing to my invention, showing the brake at rest

Figure 9 on Sheet 2 18 a plan of the same
Instead of the ordinary long hand lever on one side of the wagon, I have two
long hand levers, (one on each side of the wagon) each of which 18 divided into
two portions A and B. One end of lever A has a jaw, A¹, formed at one side,
which is made to receive one end of lever B Lever B has an eye B¹ formed on
it near one end, which fits in jaw A¹ of lever A, and is connected to it by pin O
passing through jaw A' of lever A and eye B' of lever B. Lever B 18 made to
fit vertically in the jaw A', but horizontally a little play is allowed between
levers A and B in the joint, so that lever B may move horizontally on the pin C
as a centre, but vertically levers A and B act as a rigid bar when pressed down
at the handle B of lever B The levers A and B are made rights and lefts,
and when the eyes A² of the right and left hand levers A are fixed on shaft D,
one at each end, the jaws A' on the two levers A are turned inwards and towards
each other. At one end of each of the two levers B and at an equal distance
past the eye B on the same level, I form two eyes B³ and B, which may
be made solid on the levers B, or attached to levers B as separate parts.
The eyes B¹ of the two levers B are placed in jaws A¹ of the two levers A and
secured by pin C. The two levers B are connected together by two bars or rods E
which are placed diagonally with each other across the wagon. One end of each
of the bars or rods E is connected to eye Bª on one lever B, and the other
end is connected to eye B on the other lever B, by pins or bolts. Thus when
operating the brake if the handle B of one of the levers B is pulled outwards
or pushed inwards, a corresponding movement takes place simultaneously with
the other lever B, which is on the other side of the wagon, and which is not
directly actuated
The brake guards, Figures 6 and 7 are of the ordinary type with teeth, the
levers B have projections formed on to engage with these teeth, which retain
the levers down when applied. The guards also have the usual iests for
retaining the levers when brake 18 off.
In order to ensure the levers B engaging the teeth of the brake guards,
Figures 6 and 7, a spring F Figure 4 is fixed to lever A, or other convenient
place.
All the parts of the improved brake are intended to be made of iron, steel, or
suitable strong metal, or of compound of metals or of other suitable materials,
and the form or shape and also the arrangement may be modified to suit different
designs of vehicles according to circumstances.
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 1s―
The general construction and arrangement of parts together constituting an
improved lever brake for railway wagons, and fike vehicles, having the com-
bination of two side levers which are each made in two parts and jointed and
the handle ends of each long lever are connected together substantially in the
way described, so that when one hand lever 18 pulled outwards or pressed inwards,
a corresponding and simultaneous movement takes place with the lever not
directly operated and on the other side of the wagon
