Improvements in Brake Apparatus for Vehicles such as Railway
Waggons.
I, HAYDON PARKER of 81 Westdown Road Stratford in the County of Essex
Railway Coachmaker do hereby declare the nature of this invention to be as
follows:-
The brakes for railway waggons are now generally actuated either by a long
horizontal hand lever on one side of the vehicle or by one such lever on each side, both
levers being fixed on the same transverse shaft. In some cases the said hand lever
or one of the said two hand levers is furnished on its inner side with a tooth which
when the brake is off engages with a tooth rack fixed to the underframe of the
vehicle but which for the purpose of shifting the position of the lever can be
disengaged therefrom by pulling the hand lever in a direction away from the
side of the vehicle. Now in order that the hand lever on the other side may be
disengaged in a similar manner that is to say by also pulling it away outwardly
from its side of the vehicle I connect the two hand levers near their outer ends or
at other suitable distance from their shaft by means of two rods jointed respectively
to each end of a double armed lever situate at some point between the two hand
levers, and having its fulcrum pin working in a slotted bracket or some equivalent
thereof attached to the underframe and in which it is capable of sliding up and
down so that said double armed lever and the rods jointed thereto can partake of
the simultaneous up and down motion of the hand levers. Or instead of two rods
jointed to a double armed lever I may connect the two hand levers by means of a
rod bent in zigzag shape so that an intermediate limb or portion of it takes the
place of the double armed lever; or one end of the rod may be jointed to the said
intermediate portion instead of being rigid therewith. I am thus able to apply
the brake from either side of the vehicle and to release it from either side
irrespective of the side on which it has been applied, while the pull on the hand
lever in disengaging the brake will be in the same direction on whichever side of
the vehicle it may happen to be worked, that is to say, always away from the side
of the vehicle. Or the double armed lever may have its fulcrum on a lever fixed
on the hand lever shaft in the same direction as the hand levers and thus following
their movements when worked up or down.
A similar arrangement may be applied to brakes worked from either side of the
vehicle by means of a vertical hand lever on each side, both being fixed on the
same transverse shaft. With this arrangement both the hand levers are provided
with a tooth or rib on the inner side, the one engaging with a tooth rack and the
other with a slotted rest or stop when in its central or "off" position.
I connect the two hand levers by two rods jointed respectively to each end of a
double armed lever having its fulcrum on a lever mounted on the aforesaid shaft.
Or I connect them by a rod bent in zigzag shape or one bent partly in zigzag shape
and a rod jointed thereto as above described.

Improvements in Brake Apparatus for Vehicles such as Railway
Waggons.
I, HAYDON PARKER late of 81 Westdown Road, Stratford in the County of
Essex, but now of 54 Avenue Road Forest Gate in the County of Essex, Railway
Coachmaker 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 :-
The brakes for railway waggons are now generally actuated either by a long
horizontal hand lever on one side of the vehicle or by one such lever on each side,
both being fixed on the same transverse shaft. In some cases as in my Patent
Specification 12557 of 1895 the said hand lever or one of the said hand levers is
furnished on its inner side with a tooth which when the brake is off engages with a
tooth rack fixed to the under frame of the vehicle but which for the purpose of
shifting the position of the lever can be disengaged therefrom by pulling the hand
lever in a direction away from the side of the vehicle. Now in order that the
hand lever on the other side may be disengaged in a similar manner that is to say
by also pulling it away outwardly from its side of the vehicle I connect the two
hand levers near their outer ends or at other suitable distance from their shaft by
means of two rods jointed respectively to each end of a double armed lever situate
at some point between the two hand levers and having its fulcrum pin working in
a slotted bracket or some equivalent thereof attached to the underframe and in
which it is capable of sliding up and down so that said double armed lever and the
rods jointed thereto can partake of the simultaneous up and down motion of the
hand levers.
Figs. 1, 2 and 3 are side view, plan and end view of such an arrangement. The
two hand levers A and A' are near their outer ends connected by means of two
rods D and D jointed respectively to each end of a double armed lever L having
its fulcrum pin working in a slotted bracket H attached to the underframe of the
vehicle and in which it is capable of sliding up and down, so that the lever L and
the rods D and D' can partake of the simultaneous up and down motion of the hand
levers A A G and G are the racks for holding the levers A and A¹ in the off
position. The lever A¹ is continued beyond its fulcrum A° and is by a rod S and
lever T connected to the usual double armed lever C to which the push rods K
and K' are jointed which actuate the brake blocks E and E that are suspended by
hangers F and F in the usual way. The lever A may as shewn be made double
armed the short arm carrying a weight to balance the parts S and T. It will be
noticed that there are no cross connections that might be said to be in the way of a
bottom door of a vehicle if so fitted so that this arrangement of parts having the
hand lever shaft B and the rods D and D' and lever L near one end of the vehicle
is well adapted for the so called hopper waggons having falling bottom door or
doors. And I am able to apply the brakes from either side of the vehicle and to
release them from either side irrespective of the side on which it has been applied,
while the pull on the hand lever A or A' in disengaging the brake will be in the
same direction on whichever side of the vehicle it may happen to be worked that is
to say always away from the side of the vehicle.
In another arrangement shown in Figs. 4, 5 and 6 being side view plan and end
view the double armed lever L has its fulcrum on a lever H fixed or forged on the
hand lever shaft B in the same direction as the handle end of the said levers, and
thus following their movements when worked up or down.
Fig. 7 is a plan view of an arrangement similar to Fig. 5 except that the lever H

page_text: and the double armed lever L are omitted, and the hand levers A A' are rigidly
connected across by a rod D, so that the said hand levers work parallel when
moved laterally for disengagement from the rack G or G¹.
Fig. 8 is an end view and Fig. 9 a plan of an arrangement similar to Figs. 4, 5
and 6 but applied to vertical hand levers A A' one on each side both being fixed
on the same transverse shaft B so that the brake can be worked from either side;
arrangements with a vertical lever on each side of the vehicle are described and
shown in my aforesaid Patent Specification 12557, and this part of my present
Both the hand levers
invention is applicable to such arrangements or constructions.
are provided with tooth or rib on the inner side, the one engaging with a tooth rack
and the other with a slotted rest or stop when in its central or "off" position.
I connect the two hand levers A A' by two rods D and D' jointed respectively to
each end of a double armed lever L having its fulcrum on a lever H mounted or
forged on the shaft B.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. The application to hand brake levers, one on each side of a railway waggon
or other vehicle, of connecting mechanism consisting of a double armed lever having
its fulcrum working in a guide fixed to the underframe of the vehicle and connecting
rods between said double armed lever and the hand brake levers substantially as
set forth.
2. The construction of hand brake lever mechanism in which the hand levers A
and A' fixed on a cross shaft B are connected by a double armed lever L having
its fulcrum in a guide H fixed to the underframe of the vehicle and by rods Ď
and D¹, while the hand lever A is connected to, the brake lever C by a rod S and
a lever T substantially as described with reference to Figs. 1 to 3.
3. The application to horizontal and vertical hand brake levers one on each side
of a railway waggon or other vehicle of connecting mechanism consisting of a
double armed lever mounted on a lever on the handbrake lever shaft and connecting
rods between said double-armed lever and the hand brake levers substantially as
set forth.
4. The construction of hand brake lever mechanism in which the hand levers A
and A fixed on a cross shaft B are connected by rods D and D' and a double
armed lever L the fulcrum of which is in a lever H on the said shaft while the
hand lever A is connected to the brake lever C by the rod S and lever T
substantially as described with reference to Figs. 4-6.
5. The construction of hand brake lever mechanism in which the hand. levers A
and A fixed on a cross-shaft B are connected by a rod D while the hand lever A.
is connected to the brake lever C by the rod S and lever T substantially as
described with reference to Fig. 7.
6. The construction of hand brake lever mechanism in which the vertical hand
brake levers A and A' fixed on a cross-shaft B are connected by rods D and D' and a
double armed lever L the fulcrum of which is on a lever H on the said shaft
substantially as described with reference to Figs. 8-10.
