PROVISIONAL SPECIFICATION.
Improvements in Brake Mechanism for Railway Vehicles.
I, WILLIAM SAMUEL LAYCOCK, of Victoria Street Works, City of Sheffield,
Manufacturer, do hereby declare the nature of my invention to be as follows:-
-
This invention relates to the levers and other mechanism in connection with the
hand brakes of railway vehicles, more especially wagons, and particularly in
"Mortons."
combination with the arrangement of hand brake known as
In Mortons brake the mechanism is actuated by forcing down a long side lever
which is retained in position when the brake is on, by passing a pin into one of
a series of holes provided for that purpose, and when the brake is to be released
it is first necessary to press down the lever to free the pin from pressure and then
withdraw it from the hole which permits the lever to be raised and the brake
taken off.
According to this invention instead of one long lever as in Mortons and others
I use two connected levers, one a short one (upon the cross shaft which operates
the brake blocks) and connected by a vertical link to the end of the long lever
which is pivotted and supported from the wagon frame at a short distance from the
vertical link.
The free end of the lever passes between the sides of a suspended rack,
supported by a cross shaft held in bearings fixed to the underside of the wagon
frame.
A projection upon the lever engages with the teeth of the rack, but when the
rack is moved back by turning it upon its axis, the lever is disengaged and the
brake taken off.
To release the lever from the rack the rack is provided at its lower end with
a projecting pin upon which the foot of the operator can be placed and the rack
pushed back as before mentioned.
When the brake is to be put on, all that is necessary to do this is to press down
the lever, which automatically engages with the teeth of the rack.
The cross shaft from which the rack depends reaches across from side to side of
the wagon and there is a rack fixed upon each end so that the brake can be both
applied and taken off from either side of the wagon.

I, WILLIAM SAMUEL LAYCOCK of Victoria Street Works, City of Sheffield
Manufacturer do hereby declare the nature of this invention and in what manner
the same has to be performed, to be particularly described and ascertained in and
by the following statement :-
This invention relates to fan arrangement of mechanism for operating hand

page_text: brakes applied to railway vehicles and more especially to the wagons of rolling
stock, such mechanism being of great advantage when used in combination with
the brake known as Morton's Patent.
My invention is illustrated in the annexed sheet of drawings.

Fig. 2, the end view of the apparatus as carried upon both sides of wagon.
Fig. 3, side view of the rack.
Fig. 4, counterbalance weight and arm.
Fig. 5, inside of hand lever with catch.
I will describe my invention as applied to "Mortons" plan in which a long side
lever is used, and which when forced down to put on the brake is retained in that
position by passing a pin into one of a series of holes provided for that purpose, and
when the brake is to be released it is necessary to first press down the long lever
to free the said pin, and then to withdraw it from the hole before the brake block
can be removed from the wheel.
Now according to my invention, instead of one long lever, I use two connected
levers A, and B, connected by a vertical link C. The longer lever A, is pivotted
and supported at D, upon a casting secured to the wagon frame. The free end of
the lever A, passes between the two sides of the rack E, which is securely fixed
upon a cross shaft F, supported by the spring shoe G, secured to the wagon
frame.
The rack E, consists of two side plates, the edge of one plate being provided
with a series of ratchet teeth or their equivalents, or both plates may be toothed
if preferred, and between the plates the lever A, is passed and can be raised and
lowered.
Upon the lever A, is a catch H, arranged to engage with the teeth of the rack,
and to cause rack to engage, and to retain them in gear a counterbalance I, upon
an arm J, is fixed upon the shaft F.
At the bottom end of the rack is a pedal or projecting pin K, upon which the
foot of the operator is placed, so that the rack can be pushed back out of gear
with the catch H, which instantly releases the lever A, and the brake block L.
When it is desired to put on the brake, the lever A, is pressed down, the
rack E, automatically giving way until the lever stops when the catch H, engages
with teeth of the rack which retain it until released as before described.
A similar apparatus is fixed upon each end of the cross shaft, so that the brake
can be operated from either side of the wagon.
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 brake mechanism herein before described and set forth.
2. In mechanism for actuating hand brakes the combination with a hand lever
such as A, of a swing rack E, the teeth of which will engage with a catch H, upon
the said lever, as hereinbefore described and shown.
•
3. In mechanism for actuating hand brakes a rack fixed upon a rocking shaft
which extends across the wagon frame, provided with a projecting pedal K, aud
with a series of teeth or the like to engage with the hand lever of the brake
substantially as described and shown.
