COMPLETE SPECIFICATION.
Improvements in Brakes for Railway and Tramway Vehicles.
I JOSEPH GAMES of Tramway Carriage Works, Cleveland Street Birkenhead
in the County of Chester Draftsman, 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 invention relates to railways or tramways in which the cars or carriages
travel over steep inclines and in which there is a rail or rails having a slot
or slots.
The object is to provide efficient means for stopping the cars or carriages on the
said inclines. The invention consists essentially in fitting the car or carriage with
a piece or pieces which passes or pass through the slot or slots, and in combining
therewith one or more movable attachments so disposed and operated as to be
capable of gripping or seizing two sides of the rail or rails.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a transverse vertical section and Fig. 2 an elevation of a brake con-
structed in accordance with my invention. a is part of the frame of the carriage.
b is the slotted rail. c is a piece or link pivotted at d to an excentric e carried by
a shaft free to move in bearings g on the frame a. To the lower end of the piece.
or link c is pivotted the block or attachment h having a wearing face i secured
thereto by bolts and nuts j. k is a block or attachment similar to h free to slide to
and fro on the piece or link c and suspended from the body of the carriage by
springs 1. m are arms pivotted to the block k by the pin n and to the frame a, by
the bolts and nuts o. The said block k is also pivotted to the excentric e by means
of arms p. 9 operating lever attached to the excentric shaft f. With the parts
in the position shown, the carriage is free to move. When the lever a is moved in
the direction of the arrow the excentric is caused to turn and the block k is lowered
until it rests on the top of the rail whilst the block h is raised until it bears on the
under shoulder b¹ of the rail. The rail is thus gripped between the two blocks and
the carriage is brought to rest.

page_text: There may be two rails instead of one, and two block carrying pieces i
desired.
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 1
claim is :-
The combination of two blocks with mechanism for causing them to grip two
sides of a rail substantially as set forth.
