Improvements in Securing Buffer Spindles in the Cylinders of Spring
Buffers for Railway and like Vehicles.
$
I, WILLIAM GEORGE GILES, of 40, Fortune Gate Road, Harlesden, in the County
of Middlesex, Engineer's Assistant, do hereby declare the nature of this invention
to be as follows:-
Improvements in the means employed for securing buffer spindles in the
cylinders of spring buffers for railway and like vehicles and has for its object the
greater facility in putting together and taking apart the separate portions of these
buffers, and to enable repairs or replacements to be carried out without the labour
of skilled mechanics these buffers being arranged that they can be repaired at
any time on the line by unskilled workmen and without the necessity of special
tools.
To keep the buffer spindle in its position in the buffer cylinder I form a cotter
hole through that portion of the buffer spindle directly behind the inside of the
front portion of the buffer cylinder. Into this cotter hole I introduce two cotters
having projections formed on them for engaging and abutting against the inside
front of the buffer cylinder and preventing the buffer spindle from leaving the
cylinder.
To secure the cotters in place, I use the ordinary buffer plunger washer but
shape recesses in the face suitable for receiving and engaging the projections on
the cotters, this washer when passed over the buffer spindle and fixed in place at the
front of the buffer spring is then held in position by the pressure of the buffing
spring.
The parts are made in wrought iron, steel, or other metal.

Improvements in Securing Buffer Spindles in the Cylinders of Spring

I, WILLIAM GEORGE GILES, of 40, Fortune Gate Road, Harlesden, in the County
of Middlesex, Engineer's Assistant, 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:-

page_text: This invention relates to improvements in the means employed for securing
buffer spindles in the cylinders of spring buffers for railway and like vehicles and
has for its object the greater facility in putting together and taking apart the
separate portions of these buffers, and to enable repairs or replacements to be
carried out without the labour of skilled mechanics these buffers being arranged
that they can be repaired at any time on the line by unskilled workmen and with-
out the necessity of special tools. For this purpose in a buffer according to this
invention and in order that my invention may be clearly understood I will proceed
to describe the same with the aid of the accompanying drawing in which corre-
sponding letters of reference show parts in each of the figures.
Fig. 1 is a section through the buffer showing my invention.
Fig. 2 is a plan of the buffer.
Fig. 3 is an elevation of portion of the buffer spindle showing cotter hole.
Fig. 4 shows buffer plunger washer.
Fig. 5 shows buffer cotters.
Thus to keep the buffer spindle A in its position in the buffer cylinder B, I form
a cotter hole c, through that portion of the buffer spindle A, directly behind the
inside of the front part of the buffer cylinder B. Into this cotter hole I introduce
two buffer cotters, D, having projections formed on them for engaging and abutting
against the inside front of the buffer cylinder B and preventing the buffer spindle A
from leaving the buffer cylinder B. To receive the cotters D in place I use a
buffer plunger washer E but shape recesses F in the face suitable for receiving and
engaging the projections on the cotters D.
The washer E when passed over the buffer spindle A and fixed in place at front
of the buffer spring G is then held in position by the pressure of the buffer spring G.
The parts are made in wrought iron; steel, or other metal and may be modified
in shape to suit requirements, and india rubber springs may be used in place of
steel springs as shewn on drawing.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:-
A buffer for railway and like vehicles having a buffer spindle with a cotter hole
formed in it for the reception of two cotters, the cotters being retained in position
by the buffer plunger washer which has recesses formed in its face for receiving
the projections on the buffer cotters the whole combined as shewn on drawing
and described herewith.
