PROVISIONAL SPECIFICATION.
:
Improvements in Buffers of Railway Carriages, Wagons, and other.
Vehicles.
I JAMES WALLACE of 29 King Street, Wigan, Lancaster, India Rubber Merchant
do hereby declare the nature of my said invention to be as follows:-
This invention consists in employing a series of steel or other metal discs with an
india rubber ring or buffer interposed between them, as described in the specification
of Letters Patent No. 4370 granted to me on the 27th October 1879 in the con-
struction of a railway buffer spring for carriages, wagons and other vehicles.
In performing my present invention 1 mount the buffer with its rod in the undor-
framework of the vehicle in the usual manner but the extremity of this rod passos
through a bracket (affixed to the bottom of the vehicle) and there is furnished with a
screw nut. Between this bracket and a flange or collar upon the buffer rod are
mounted the series of metal discs and india rubber rings constituting the buffer spring
and which may be tightened up by the screw nut.
The action of this improved buffer is as follows :-
As the buffer is pressed inwards the india-rubber rings become compressed and so
give the necessary yielding or elastic action to the buffer whilst immediately they are
let-go again the buffer springs outwards to its original extent.
In some cases the buffer rods at opposite ends of the vehicle terminate beneath the
body of such vehicle in a rectangular frame and which thus embraces the serries of
discs and rings appertaining to both buffers.

COMPLETE SPECIFICATION.
Improvements in Buffers of Railway Carriages, Wagons, and other
Vehicles.
I JAMES WALLACE of 29 King Street, Wigan, Lancaster, India Rubber Merchant
do hereby declare the nature of my said 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 consists in employing a series of steel or other metal discs with an
india rubber ring or buffer interposed between them as described in the specification
of Letters Patent No. 4370 granted to me on the 27th October 1879 in the con-
struction of a railway buffer spring for carriages, wagons and other vehicles.
On the accompanying drawing Fig. 1 represents a plan view of the under frame-
work of a railway carriage having my improved buffer applied. Figs. 2 and 3
illustrate two forms of discs (single and double) employed and Fig. 4 are similar
views of the elastic ring or buffer. These discs and rings are fully described in my
former specification.
In performing my present invention I mount the buffer a with its rod b in the
under-framework c of the vehicle in the usual manner but the extremity of this rod b
passes through a bracket c (affixed at the bottom of the vehicle) and there being
screwed is furnished with a screw nut d. Between this bracket c and a flange or
collar e upon the buffer rod 6 are mounted the series of metal discs and india
rubber rings g constituting the improved buffer spring and which may be tightened
up by the screw nut d.

page_text: The action of this improved buffer is as follows:-
As the buffer is pressed inwards the india-rubber rings g become compressed and
so give the necessary vielding or elastic action to the buffer whilst immediately they
are let-go again the buffer springs outwards to its original extent.
In Fig. 51 illustrate a plan view of a buffer on my improved principle and without
the long rod and when I desire to construct a "through" Buffer I employ a centre
socket as indicated in plan view Fig. 6.
In some cases the buffer rods at opposite ends of the vehicle terminate beneath the
body of such vehicle in a rectangular frame and which thus embraces the series of
discs and rings appertaining to both buffers.
It will he obvious that in the construction of my improved buffer any number of
my improved discs and india-rubber rings may be employed according to the length
of stroke required.
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 1
claim is
1st. The improved construction and arrangement of buffer for railway carriages,
wagons and other vehicles substantially as herein before described.
2nd. In the construction of a spring buffer the employment of a series of discs and
india-rubber rings mounted and operating substantially as and for the purposes
hereinbefore described.
Dated this 21st day of May 1889.
