PROVISIONAL SPECIFICATION.
Improvements in Brake Apparatus for Vehicles such as Railway
Waggons.
I, THORVALD KLEIN, of Suffolk House, Laurence Pountney Hill, in the City
of London, Mechanical Engineer do hereby declare the nature of this invention to
be as follows:-
This invention has reference to improvements in brake apparatus for vehicles
such as railway waggons of the kind in which the brake block or blocks is or are
moved into the "on" ог "off" positions as required by one or other of two hand
levers arranged at the respective sides of the vehicle, and each capable of moving
in a vertical or approximately vertical plane. In brake apparatus of this kind as
heretofore constructed each lever is locked in the " on or "off" position, by a
holding device such as a pin and the lever can only be locked or unlocked by an
operator at the same side of the vehicle as the lever."
"
"
Now the object of this invention is to enable brake apparatus of the kind referred
to, to be applied and released or taken off and to be secured in the attitude corre-
sponding either to the " on or that corresponding to the "off" position of the
brake by an operator working either of the two levers from either side of the
vehicle.
For this purpose I connect the free ends of the two brake levers by a transverse
rod or connection and provide at one or both sides of the vehicle a suitable holding
device that may be a plate or frame formed with a series of notches or teeth. The
hand lever or each lever if two holding devices be used, is so formed as to be
capable of being engaged with or disengaged from the corresponding holding
device. The arrangement is such when two holding devices are used, that when
one lever is disengaged from or engaged with its corresponding holding device by
an operator at one side of the vehicle, the lever at the opposite side of the vehicle
will be simultaneously disengaged from, or engaged with its holding device, and
that when the levers are disengaged the brake apparatus can be moved into the
on or "off" position as required.

COMPLETE SPECIFICATION.
Improvements in Brake Apparatus for Vehicles such as Railway
Waggons.
I, THORVALD KLEIN, of Suffolk House, Laurence Pountney Hill, in the City
of London, Mechanical 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 :-
This invention has reference to improvements in brake apparatus for vehicles
such as railway waggons of the kind in which the brake block or blocks is or are
moved into the "on or "off" positions as required by one or other of two hand
levers arranged at the respective sides of the vehicle, and each capable of moving
in a vertical or approximately vertical plane. In brake apparatus of this kind as
heretofore constructed each lever is locked in the " on or "off" position, by a
"

page_text: holding device such as a pin, and the lever can only be locked or unlocked by an
operator at the same side of the vehicle as the lever.
"
Now the object of this invention is to enable brake apparatus of the kind
referred to, to be applied and released or taken off, and to be secured in the
attitude corresponding either to the " on or that corresponding to the "off"
position of the brake by an operator working the two levers from either side of the
vehicle.
For this purpose I connect the free ends of the two brake levers by a transverse
rod or connection and provide at one or both sides of the vehicle a suitable holding
device that may be a plate or frame formed with a series of notches or teeth. The
hand lever, or each lever if two holding devices be used, is so formed as to be
capable of being engaged with or disengaged from the corresponding holding
device by a lateral movement.
In the accompanying drawings,
Figs. 1, 2 and 3 are respectively side, plan and end views of so much of a railway
vehicle as is necessary to illustrate the application thereto of brake apparatus
according to my invention.
1 is a transverse rock shaft provided at each end with a hand lever 2 and from
which motion can be transmitted to brake blocks 3 by any known or suitable means
as for example by a lever 4 fixed on the shaft, and links 5 connecting the two arms
of the lever with the brake blocks. The two hand levers are, according to this
invention, connected by a transverse rod or connection 6 and each lever is formed
or provided with a tooth or projection 7. At each side of the vehicle is a holding
device consisting of a rack 8 carried by a fixed strap 9, and which rack is adapted
to hold the projection 7 on the corresponding hand lever, when this lever has been
moved into position to apply the brake. In this arrangement each holding device
is, as shewn more clearly in Fig. 3, placed at the right hand side of the corre-
sponding hand lever. With the arrangement described it will be seen that when
either of the hand levers 2 is moved laterally to disengage or engage its projection 7
from or with the corresponding holding device, the hand lever at the opposite side
of the vehicle will be simultaneously disengaged from or engaged with its holding
device, and that when the hand levers are disengaged, the brake apparatus can be
moved into the "
"
on or "off" position as required. When in the "on" position,
the projections 7 on the levers can be caused to engage with, so as to be held by,
the racks 8 of the holding devices. The hand levers may for this purpose be so
mounted that each of them has a constant tendency to move towards its corre-
sponding holding device.
Each hand lever is held in the "off" position by causing it to rest within a
recess 8 at the top of the corresponding holding device.
In the construction shewn in Figs. 4, 5 and 6, which are similar views to
Figs. 1, 2 and 3 respectively, the holding devices are each arranged at the inner
side of the corresponding hand lever. With this arrangement it will be seen that
when one lever is disengaged from or engaged with its corresponding holding
device by an operator at one side of the vehicle, the lever at the opposite side of
the vehicle will be respectively engaged with or disengaged from its holding device,
and that the hand levers are free to be moved in a vertical direction to put "on" or
take "off" the brakes when they occupy an intermediate position in which neither
of them are engaged with their holding devices. In this arrangement the outer
side of each strap 9 is formed with a recessed part 11 to hold its corresponding
hand lever in the "off" position when necessary, at which time the other hand
lever will be held within the recess 8" at the top of its holding device.
Fig. 7 is an end view to an enlarged scale of part of one of the holding devices
used in this arrangement, shewing the various positions of one of the hand levers in
relation to such holding device. a and b shew the positions of the hand lever when
held in the "off" positions by the recessed parts 11 & 8 of the strap 9 and plate 8
respectively; its position when engaged with the rack 8; d its position when
being moved to put on or take off the brake; and e the position of the one lever

page_text: when out of gear whilst the other lever is engaged with the holding device on the
opposite side of the vehicle. In other respects the arrangement shewn in Figs. 4
to 7 inclusive is similar to that illustrated in Figs. 1, 2 and 3.
As will be obvious the hand levers may be connected in various ways, and that
one holding device only may be used.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
A hand operated brake apparatus of the kind hereinabove referred to wherein
two hand levers are arranged one at each side of the vehicle to which the apparatus
is fitted and are connected by a transverse rod or connection so that they will move
together on either of them being operated and that the brake can be applied or
taken off and both levers can be locked or both released by an operator from either
side of the vehicle, suitable locking devices being for this purpose arranged in
relation to the connected levers or one of them substantially as described with
reference respectively to the examples illustrated in Figs. 1 to 3 inclusive and in
Figs. 4 to 7 inclusive of the drawings annexed.
Dated this 8th day of December 1891.
