PROVISIONAL SPECIFICATION.
Improvements in or appertaining to Certain Brake Mechanism of
Vehicles Mounted on Bogle Wheels.
I, LUKE ROBERTS, of Union Foundry, Cutler Heights, Tong, near Bradford in
the County of York, Engineer, do hereby declare the nature of this invention to be
as follows:-
This invention relates to improvements in the mechanism described in the
Specification of a previous application for a Patent by the present applicant
No. 10,151 dated the 1st July 1890 in which the brake is arranged in connection
with the draw-bar and its object is to enable this type of brake to be applied to
vehicles mounted upon bogies such as railway vehicles and tram cars constructed
upon the bogie principle.
For this purpose I connect the brake mechanism of each bogie to a circular piece
or disc normally lying approximately concentric with the bogie seat and having a
central opening surrounding the seat large enough to allow the circular pieces to be
capable of a limited longitudinal motion in relation to the vehicle. The draw-bar
is provided with two circular links or openings adapted to fit the peripheries of the
said circular pieces and thus connect them together.
By this arrangement the two bogies may be at a considerable angle to each other
without interfering with the motion of the draw-bar and action of the brake.
Dated this 28th day of April 1891.

COMPLETE SPECIFICATION.
Improvements in or appertaining to Certain Brake Mechanism of
Vehicles Mounted on Bogie Wheels.
I, LUKE ROBERTS, of Union Foundry, Cutler Heights, Tong, near Bradford
in the County of York, 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 relates to improvements in the mechanism described in the
Specification of Letters Patent granted to the present applicant and another
No. 10,151 dated the 1st July 1890 in which the brake is arranged in connection
with the draw-bar and its object is to enable this type of brake to be applied to
vehicles mounted upon bogies such as railway vehicles and tram cars constructed
upon the bogie principle.
For this purpose I connect the brake mechanism of each bogie to a circular piece
or disc normally lying approximately concentric with the bogie seat and having a
central opening surrounding the seat large enough to allow the circular pieces to be
capaole of a limited longitudinal motion in relation to the vehicle. The draw-bar is
provided with two circular links or openings adapted to fit the peripheries of said
circular pieces and thus connect them together.
By this arrangement the two bogies may be at a considerable angie to each other
without appreciably interfering with the motion of the draw-bar and action of the
brake.
To fully describe my invention reference is made to the accompanying sheet of
drawings forming a part of the Specification in which similar letters of reference
indicate corresponding parts in each of the figures.

page_text: Figure 1, represents a side elevation of the two bogies of a vehicle fitted with my
improvements. Figure 2, is a plan view of the same with the bogie on the left hand
side omitted for the purpose of more clearly showing my improvements.
The levers g, g, and g', g¹, mounted on the rocking shafts R, R for operating the
brake mechanism of the bogies A, A, are also shown and described in the Specifica-
tion of the above cited Letters Patent. The circular pieces or discs B are mounted
on and connected to each pair of levers g', g¹ the tops of which pass through slots a
and are secured between the lugs e formed on B by means of pins i. The circular
pieces B are each made with an elongated central opening through which the
bogie seats D for supporting the car or vehicle pass. The draw-bar E which is
continuous from one bogie to the other is made with two circular links or openings F, F
fitting the peripheries of and mounted upon the circular pieces B, B. These
circular pieces are provided with shoulders or flanges j on which such links rest
.and the projecting heads r of the bolts & passed through B keeps them in that
position.
The ends E¹, E¹ of the draw-bar E are arranged to project beyond the vehicle in
the ordinary manner and are provided with any suitable couplings.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare what I
claim is :-
The combination with a bogie vehicle fitted with the type of brake mechanism
herein referred to, of the improved connection between the brake mechanism and
the draw-bar, substantially as herein shown and described.
