Improvements in Brakes for Tram-line Vehicles.
I GEORGE FREDERICK MILNES of Cleveland Street Birkenhead in the County
of Chester 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 :-
The object is to provide a simple and efficient brake for vehicles used on tram
lines or rails.
The invention consists essentially in the combination of a conjoined brake block
and shoe or skid with a hanger and operating rod pivotted to the said block.
The operating rod is actuated by means of levers or in any desired way.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a side view, and Fig. 2 a plan of part of a bogie tram car fitted with my
improved brake. Fig. 3 is an enlarged view of the brake. a, is the bogie frame,
b, the car frame, c wheels, d conjoined brake block and skid, e, hanger pivotted to
the block at f, and suspended from the pin g. The pin g, is carried by a spring h
secured to the bogie frame a. is the operating rod pivotted to the brake block at j,
and attached to the levers and hand gear k. l, is an operating rod connected in any
convenient manner to the traction gear, and to the hand gear k by a chain m, so
that the hand gear acts independently of the traction gear which only comes into
operation in case of a breakaway or like emergency. n rack for fixing the traction
brake gear in position when operated. The hand and traction or automatic gear
may be as shewn or may be of any usual or convenient construction, and their
construction and operation are well understood. It will be observed that the block d,
acts both as a brake against the wheel and as a skid against the rail. The spring h
allows of the block adjusting itself to inequalities of motion between the parts when
in acting position.
Fig. 4 is a view showing my improved brake with the hanger e provided with a
slot e to allow for adjustment.
Fig. 5 is a view of a traction gear connection which may be used instead of a
chain

page_text: Fig. 6 is an elevation and Fig. 7 is a plan showing my improved brake attached to
an ordinary or non bogie car, here the hand gear k, is as shown or may be of any
ordinary type. The same letters of reference are applied to equivalent parts in
Figs. 1. 2. 3. and 4.
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 :-
First. The conjoined brake block and skid d, hanger e, and operating rod i
combined substantially in the manner and for the purpose set forth.
Second. The improved car brakes substantially as herein specified.
