Improvements in Brake Apparatus for Vehicles such as
Railway Wagons.
We, WILLIAM PANTER of 27, Aldebert Terrace, South Lambeth Road, in the
County of Surrey and JOHN CHARLES TATTE and THOMAS WILLIAM CARLTON
both of 63, Queen Victoria Street, in the City of London, Engineers, do hereby
declare the nature of this invention to be as follows:
This invention has reference to brake apparatus (for vehicles such as railway
wagons) that may be readily operated by hand from either side of the vehicle.
The brake block carrying the brake shoe is suspended from a part of the
vehicle, and has connected to it a lever itself connected at one end by a link or
rod to one of the axle box horn plates; through its other end passes a rod to
which movement may be imparted, to apply or to release the brake, by a hand
lever that extends transversely or approximately so of the vehicle and has its
ends conveniently arranged for being actuated from either side of the vehicle.
The hand lever is provided with a tooth or projection that can be engaged with
or disengaged from one or other of a series of notches formed in a suitable plate
or frame attached to the vehicle. By the means described the brake block and
shoo can be firmly held either in the on or the off" position as required.
The lever on one side is or may be held in position by a spring, which also
forms a fulcrum to release the brake.

In order that the brake shoe may be applied without shock and the pressure
thereof on a wheel be adjusted as required a spring may be arranged between
the lever that is connected to the brake block and the rod through which such
lever is actuated. Means are or may be provided whereby the effective length
of the connecting rod between the hand lever and the brake block lever can bo
adjusted from time to time to compensate for wear of the brake shoe.

Improvements in Brake Apparatus for Vehicles such as
Railway Wagons.
We, WILLIAM PANTER, of 27, Aldebert Terrace, South Lambeth Road, in the
County of Surrey, and JOHN CHARLES TAITE and THOMAS WILLIAM CARLTON
both of 63, Queen Victoria Street, in the City of London, Engineers, 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:
This invention has reference to brake apparatus (for vehicles such as railway
wagons) that may be readily operated by hand from either side of the vehicle
for the purpose of applying or releasing the brake block or blocks and for fixing
the same in the on or off"
positions as required.

"
For this purpose the brake block or blocks is or are connected through suit-
able mechanisin with a hand lever that extends transversely or approximately
so of the vehicle and has its ends conveniently arranged for being actuated from
either side of the vehicle. The hand lever is provided with a tooth or projection
that can be engaged with or disengaged from one or other of a series of notches
formed in a suitable plate or frame forming a holding device attached to the
vehicle.
The lever on one side is or may be held in position by a spring, which may

page_text: in some cases also form a fulcrum for the lever when releasing the same from
the holding device from the side of the vehicle opposite to that at which this
device is secured.
In order that the brake shoe may be applied without shock and the pressure
thereof on a wheel be adjusted as required, a spring may be arranged between
the lever that is connected to the brake block and the rod through which such
lever is actuated. Means are or may be provided whereby the effective length
of the connecting rod between the hand lever and the brake block lever can be
adjusted from time to time to compensate for wear of the brake shoe.
As will be obvious a hand lever with holding device arranged according to
this invention may be used with brake apparatus of various constructions. In
some cases two hand levers arranged transversely or approximately so of the
vehicle may be used.
In the accompanying drawings,
Fig. 1 is a side elevation of a part of a railway wagon fitted with brake
apparatus according to this invention;
Fig. 2 is a transverse section of the vehicle with the brake apparatus in
elevation; and
Fig. 3 is a plan.
1 is a brake block with shoe hung by a link 2 from the beam 3 of the vehicle.
On the back of the block is a loop or stirrup 4 through which there passes a
lever 5 which is pivotted to the said loop or stirrup. The outer end of this lever
is connected by a rod or link G to the horn plate 7. The inner end is coupled
or connected to a rod 8, which is pivotted at its other end to a hand lever 9. This
.hand lever is pivotted at 10 to the headstock, and according to this invention
stretches across the wagon so that it can be operated from either side thereof.
It moves in a stirrup or guide 11 at one end and in this guide there are notches
12. A tooth 13 on the lever 9 can be made, from either side of the vehicle, to
take into one or other of these notches in order to keep the brake block and
attached parts in the " on or off" position after the lever has been operated.
The pressure exerted on the lever 5 by the rod 8 in applying the brake may
advantageously be transmitted through a spring 14. This enables the brake
to be applied with any desired degree of force and lessens shock when applying
the brake and during shunting operations. The spring is interposed between
the lever 5 and a nut and washer on the end of the rod 8. 15 is a coupling by
which the length of the rod can be adjusted to compensate for wear of the
brake shoe.
"
To release the brake from the side of the vehicle shewn in Fig. 1, the toothed
end of the lever 9 is lifted to bring the tooth 13 out of the notch 12 in which it
was held, and the lever then moves or is moved forward.
It can then be
secured in the off" position by engaging the tooth in the end notch 12. To
release the brake from the opposite side of the vehicle the end of the lever at
that side is depressed to lift the tooth from the notch and then it is raised to
again engage the tooth. The fulcrum pin 10 of the hand lever has sufficient
play in its bearings to enable the toothed end of the lever to be thus raised and
lowered from either side of the vehicle. A spring 16 secured to the vehicle serves
to hold up the end of the lever on the side remote from the stirrup or guide 11.
In the modification shewn in Figs. 4, 5 and 6, which are similar views to
Figs. 1, 2 and 3 respectively, the hand lever and notched stirrup or guide 11 are
shewn applied to brake apparatus in which there is a suspended brake block 1
for each of the two wheels at one side of the vehicle. In this case the two
blocks are connected by links 4° to a lever 5ª fixed upon a rock-shaft 5b upon
which the operating lever 5 is also fixed. This lever 5 is operated by the rod 8
and hand lever 9 as before.
In Figs. 7, 8 and 9 which are respectively side, end, and plan views of part
of a vehicle with brake apparatus according to this invention, the hand lever ?
is pivotted to the end of the vehicle so as to work in a vertical plane and
extends to each side of the vehicle so that it can be conveniently operated from
either side thereof. The lever is connected to the operating rod § by a rod 8°

page_text: and bell crank lever S. The brake blocks are each connected by a pair of
rods 4" to the lever 5 which is fixed upon the rock shaft 5" as in Figs. 4, 5, and 6.
In other respects also, the arrangement is similar to that shewn in these figures.
Figs. 10, 11 and 12 are respectively a side elevation, a plan or top view, and
an end elevation illustrating the application of the hand lever 9 and notched
stirrup or guide 11 to a modified arrangement of the brake apparatus fitted to a
hopper wagon, part only of which is shewn. In this arrangement there is a
brake block for each wheel of the vehicle, and the pair of brake blocks at cach
side of the vehicle are connected by links 4ª to a lever 5. The two levers 5 are
mounted upon the rock shaft 5b and each of them is connected through a spring
14 and rod S to a lever 17 that is pivotted at 18 to the vehicle. The adjacent
ends of these levers 17 are slotted and are connected by a pin and a rod Sª to
the hand lever 9, by operating which the brake blocks can be either applied to
or taken off the wheels of the vehicle, and also locked in the i:
positions as desired from either side of the vehicle.

or off"
In the arrangement of brake apparatus shewn in Figs. 13, 14 and 15 which
are respectively a side elevation, transverse section, and plan, there is a pair
of brake blocks 1 for each of the wheels at one side of the vehicle. Each pair
of brake blocks is operated by a pair of levers 5 5* that are connected at their
lower ends by the rod or link 6, and one of which namely 5* is hinged or jointed
at 19 to a rod or bracket 19 fixed to the underframing of the vehicle. The
lever 5 of one pair is connected to the lever 5 of the other pair by a rod 20 and
a link 21. Through this link 21 passes the rod 8, a spring 14 being preferably
interposed between the two as shown. With this arrangement it will be readily
seen that if the hand lever 9 be operated from either side of the vehicle, its
movement will be transmitted to each of the brake blocks 1 and will cause them
to be applied to, or taken off the wheels of the vehicle, according to the direc-
tion in which it is moved, the lever being retained in its "on or off" attitude
by engaging its tooth 13 from either side of the vehicle in one or other of the
notches 12 in the stirrup or guide 11.

In Figs. 16, 17 and 18 which are similar views to Figs. 13, 14 and 15, the
hand lever 9 is connected to the rod S, which in this case is made much shorter
than in the other arrangements herein before described, by two rods 8" 8ª.
These rods are slotted at their ends adjacent to the hand lever and are connected
thereto by pins 8 that are able to slide in the slots. With this arrangement,
as will be obvious, in whichever direction the hand leyer 9 is moved from the
normal position in which it is shown, the brake blocks 1 will be applied to the
wheel. When the lever is returned to its normal position the brake blocks will
be released but will not be positively taken off the wheel owing to the pins Sb
moving in the slots in the adjacent ends of the rods Sª, but the blocks will be
free to move away from the wheel by the action of gravity. The hand lever 9
can as in the previously described arrangements be raised or lowered from either
side of the vehicle for the purpose of engaging its projection 13 with or dis-
engaging this projection from one or other of the notches 12 in the stirrup or
guide 11. The spring 16 in this arrangement is fixed to the hand lever and
bears against the underside of the notched stirrup or guide 11 so as to normally
keep the projection 13 within one of the notches 12.
Figs. 19, 20 and 21 illustrate an arrangement of brake apparatus similar to
that shewn in Figs. 16, 17 and 18 but in which the ends of the two rods S
adjacent to the hand lever 9 are not slotted but are jointed to the lever by the
pins S so that when the lever is moved in either direction from its normal posi-
tion both rods will be operated. The other ends of the rods 8ª are jointed to
one end of a pair of links So the other end of which is jointed to the rod S. With
this arrangement the brake shoes will be put on the wheel when the hand lever 9
is moved in either direction from its normal position, and will be positively
taken off the. wheel by the lever when the same is returned to its normal posi-
tion. By the construction shewn, the point of connection A of the rods 8 with
the pair of links Se will, when the hand lever is operated, move in an arc of a
circle having its centre coinciding with the centre of motion of the lever.
.

page_text: In Figs. 22, 23 and 24 the hand lever 9 is connected to the rod S by a bent
bar S the ends of which are slotted as indicated and pass around the lever which
in this case is provided with hook shaped parts 96. With this arrangement
whichever way the hand lever is moved from its normal position the brakes
will be applied as with the arrangement shewn in Figs. 16 17 and 18 but one
of the hook shaped parts 9b will then move over one or other of the ends of the
bent bar Sa, according to the direction in which the lever is moved, in such a
manner that when the lever is being again returned to its normal position the
said part 9, will during a part of the return movement of the lever, act against
that end of the bent bar which it overlaps and will thus ensure that the brakes
shall be taken off positively.
Figs. 25, 26 and 27 are similar views to Figs. 16, 17 and 18 illustrating a
modified arrangement in which two hand levers 9 and 9 are used each arranged
to extend transversely or approximately so of the vehicle as shewn. The lever 9
is pivotted at 10 and is provided with a projection 13 and with a spring 16 as
before. The lever, 9 is pivolted at 9b and is arranged to bear upon a curved
extension 9 of the lever 9, so that by pressing the lever 9a downward the other
end of the lever 9 with projection 13 can be raised clear of the notched stirrup
by a pin that passes
or guide 11. The two levers are connected to the rod
With this arrangement by moving
through a slot in each lever as shewn.
either lever to the right or in the direction of the arrows Fig. 27, the brake
blocks will be put on, and by afterwards moving either lever in the reverse
direction or to the left, the brake blocks will be taken off. The position of the
lever 9 at one side serves as an indicator to a person at that side to shew
whether the brakes are on" or off."
Figs. 28, 29 and 30 illustrate a modified arrangement in which there are two
hand levers 9 and 9 as in Figs. 25 to 27 but these levers instead of being of the
second order as in these figures are of the first order and are arranged at or near
the centre of the vehicle. The brakes are put on when either lever is moved in
the direction of the arrows or to the left, Fig. 80, and taken off when moved to
the right and into the position shown. The brake blocks and adjacent parts
are arranged similarly to those shewn in Figs. 4, 5 and 6.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, we declare that
what we claim is:-
