BRAKING RAILWAY TRAINS
Year: 1884

page_text: I, ALEXANDER STEWART Teacher Brisbane School House Largs, Ayrshire,
Scotland do hereby declare the nature of my invention for BRAKING RAILWAY
TRAINS to be as follows:-
The brake blocks are fixed under the train, almost in contact with the wheels,
and suitable connections are made to attach the end of brake lever to the buffer
rod of each vehicle or carriage and moving in a slot in the tram of vehicle so as to
be acted upon by the buffer rod when pressed in either by shutting off steam or
pressing against preceding vehicle. The brake blocks are to be coupled that is
those in rear of the wheels coupled and also those on the front so that when speed
is slackened on the engine by shutting off steam or by applying the existing brake
power on the tender the next vehicle coming up by pressing against buffer of
engine or tender (if present tender brake be retained then the pressure will act -
on driving or other wheels of engine) and thus put on brake on it and also on
rear side of its own wheels. The next vehicle by its momentum brakes the front
side of preceding vehicle's wheels and the rear side of its own.
What I claim for this invention is-economy in first cost and upkeep, durability.
and non liability to be put out of order and thorough efficiency, and being put in
order at the beginning of a journey by taking out blocks worked by a lever at the
end of the vehicle, which are used when shunting it is always ready for action
without any attention from any person;

page_text: I, ALEXANDER STEWART of Brisbane School House Largs in the county of
Ayrshire Scotland Schoolmaster, do hereby declare the nature of my invention
for IMPROVED BRAKE FOR RAILWAY TRAINS and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:

The brake blocks on the rear of the wheels are coupled together with those
acting on the front of every vehicle to be braked. The blocks are hung on the
tram of the vehicle, the two rear blocks merely working on a hinge and worked by
the rod connecting them with the front brake i e-the one next the end of the
carriage or vehicle upon which the power is exerted This power is exerted by the
momentum of the train acting upon the buffers and thus acting upon the lever end
of first brake block working in slot in tram of vehicle so that whenever a, train is
required to be slowed or stopped by merely shutting off the steam a check is
communicated to every vehicle in the train. This is effected by the buffer rod
pressing on the lever end of the brake block next to it and communicating the
power to brake the other wheel or wheels of the vehicle. The buffer of the tender
thus brakes its own wheels as well as those of the engine if necessary and thus
by simply shutting off the steam the train can be slowed to any speed or drawn
up in a short distance thus saving life and property in event of two trains
being in danger of colliding. To prevent the brakes acting when being shunted a
rod runs under the vehicle with arms working one above and another below; these
are attached to blocks filling the space traversed by lever end of brake block which
fills up this space by means of a bar or rod extending over the top of buffers, by
the horizontal movement of which, the space is filled-up-and-the-lever-end-of-the-
brake block is prevented from moving and putting on the brakes.
In order that my invention may be better understood I append drawings in
which A is the end of buffer rod carrying buffer. B is the buffer rod C. the
brake stop.. D rod connecting brakes. E. E. shows the brake blocks connected by
the rod D. and acted upon by the impact of the buffer rod. .F. G. H. shews detail
of stop for preventing the action of the brakes when it is desired to release the
brake action.

Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is Jn oil

1. A brake or brakes constructed as and acting in the manner hereinbefore
described.
