Improved Buffer Appliances for Railway Rolling Stock, and Means
connected therewith for Automatically Applying the Brakes and
Shutting Off the Motive Power.
GEORGE GRIFFITH 42 Cheapside London E.C. Engineer EDWARD GRIFFITH
42 Cheapside London E.C. Commission Merchant do hereby declare the nature of
this invention to be as follows:-
Whereas there already is existing breaks for trains and such like conveyances,
we claim to have invented a projection, to be fixed to the conveyance, in such a
manner as shall by contact with any obstruction, immediately and automatically
apply the breaks, and shut off the motive power propelling the vehicle. In a
general way to explain our invention, we assuine to have an ordinary locomotive.
I. Through the centre of the buffer box we make a hole three or four inches in
diameter to receive the projecting arın.
II. At the outward end of the projecting arm we make a suitable striking plate.
III. Reckoning some few feet from this striking plate, we come to the, entrance
of projecting arm into the buffer box.
IV. Within the buffer box we construct a tap arrangement upon the pipè
connected with the breaks also a tap intervening the course of steam to the cylinders
of engine. These taps to be immediately turned as soon as pressure is brought to
bear upon the striking plate, thus intercepting the motive power and automatically
applying the breaks many apparent disasters may thereby be averted.
We claim to have invented a projection to automatically apply breaks and shut
off motive power of trains, and such like.

Improved Buffer Appliances for Railway Rolling Stock, and Means

Shutting Off the Motive Power.
GEORGE GRIFFITH Engineer and EDWARD GRIFFITH Commission Merchant
both of 42 Cheapside London E.C. 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:—
Whereas there already is existing brakes for trains and such like conveyances,
we claim to have invented the application of a projection, to be fixed to the
conveyance in such a manner as shall, by contact with any obstruction, immediately
and automatically apply the brakes, and shut off or exhaust the motive power
propelling the vehicle. In a general way to explain our invention; we assume to
have an ordinary locomotive, through the centre of the buffer box we make a hole,
three or four inches in diameter, to receive the projecting arm. At the outward
end of the projecting arm, we make a suitable striking plate, reckoning some few
feet from this striking plate, we come to the entrance of the projecting arm into the
buffer box. Within the buffer box we construct a tap arrangement upon the pipe
connected with the pipe of service of brakes also a tap arrangement upon a pipe
connected with the course of steam to the cylinders of engine. These taps to be
immediately turned or vent given, as soon as pressure is brought to bear upon the
D

power, thus automatically applying the brakes, many apparent disasters may thereby
be averted, by bringing the train to a dead weight simultaneously with the collision
and so prevent a smash.
