PROVISIONAL SPECIFICATION.
Improvements in Buffers for Rolling Stock.
HERBERT BARRY TILFOURD STANTON Engineer, of 188 Green Lanes.
Finsbury Park London N. WILLIAM TOZER, Merchant, of 95 Finsbury
Pavement London E.C. do hereby declare the nature of this invention to be as
follows:-
Our improvement is to remove or minimize a great source of failure in the
present design of cylinder buffers for locomotives carriages wagons &c. which
occurs in the crystalizing of the end of the centre rod of plunger which works.
through the base plate, caused by the shock of the nut or cotter recoiling against
the base plate, due to the action of backlash of the buffer spring. We remove or
greatly minimize this source of weakness by dishing the base plate or forming a
recess therein in which we insert a suitable recoil spring between the bottom of
recess and the nut or cotter on the end of plunger rod. In the type of buffer where
the base plate is already dished (as some are in use at present) for the nut or cotter
to work in, to prevent same from going outside base plate, we further dish the
base plate or provide a suitable recess nearer the front of the buffer in which the
recoil spring above mentioned is inserted. This recoil spring in combination with
the recess effects the improvement whereby the crystalizing of the end of the
plunger rod is done away with or brought to a minimum as when the backlash of
the buffer spring forces the plunger rod forward the nut or cotter of same strikes
on the inserted recoil spring thereby easing the shock on the nut or cotter the
constant repetition of which in the old type of buffer crystalizes the rod the end of
which in time drops off.

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 :-
Our improvement is to remove or minimize a great source of failure in the
present design of cylinder buffers for locomotives carriages and wagons &c. which
occurs in the crystalizing of the end of the centre rod D or spindle of plunger D,
caused by the shock of the nut or cotter recoiling against the base plate or seat
due to the action of backlash of the buffer spring E. We remove or greatly
minimise this source of weakness by dishing the base plate or forming a recess
therein B in which we insert a suitable recoil spring C between the bottom of
recess and the nut or cotter on the end of plunger rod. In the type of buffer where
the base plate is already dished (as some are at present) for the nut or cotter to

page_text: work in, to prevent same from going outside base plate, we further dish the base
plate as at A or provide a suitable recess nearer the front of the buffer in which
the recoil spring C above mentioned is inserted. This recoil spring in combination
with the recess effects the improvement whereby the crystalizing of the end of the
plunger rod is done away with or brought to a minimum as when the backlash of
the buffer spring E. forces the plunger rod forward the nut or cotter of same
strikes on the inserted recoil spring C thereby casing the shock on the nut or
cotter the constant repetition cf which in the old type of buffer crystalizes the
rod D the end of which in time drops off. Fig. 1 shews a part longitudinal section
and part elevation of buffer Fig. 2 shews a modification thereof.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is
•
A self contained buffer with either a single or double dished or recessed base
plate in combination with a recoil spring therein, substantially as described.
