IMPROVEMENTS IN BUFFERS FOR RAILWAY WAGONS OR THE LIKE
Year: 1884

page_text: I, CHARLES ROBERTS, of the firm of Charles Roberts and Company Limited, of
the Railway Carriage Works, Horbury Junction, Wakefield, in the County of York,
Railway Wagon Manufacturers, do hereby declare the nature of said Invention
for "IMPROVEMENTS IN BUFFERS FOR RAILWAY WAGONS OR THE LIKE" to be as
follows:-
The object of my Invention is to provide a simple and efficient spring buffer for
railway wagons or the like, combining in the one device a simple and efficient
spring buffer, and a method of strengthening the buffer ends and of repairing
existing dead buffers which have been in use for a length of time, particularly
where the ends have suffered damage or become so short as to be unsafe for men to
stand between the vehicles for the purposes of coupling and uncoupling them. The
said buffers will also prove to be a great advantage for use on wagons which are
constantly running on lines having sharp curves, as they would not be liable to get
buffer. locked, as is so frequently the case with the ordinary round buffers.
According to my Invention I first fix a rim or hoop of wrought iron or other
metal around the buffer end: The buffer is then placed upon the said end. The
buffer cylinder is of the shape of the buffer end. This cylinder is secured firmly to
the buffer end by being placed thereover as a socket and is preferably secured by
means of bolts passing through the buffer end. In the said cylinder the plunger
works. Both cylinder and plunger are grooved or rabitted or otherwise arranged
so that they are secured to each other when fixed in position. The buffer springs
may be made of steel or India-rubber of any suitable shape. In the interior of
the head or plunger are seats or beds to receive the springs and preferably with pins
or studs to keep them in position; the interior of the buffer may also be fitted up
with a wood lining if necessary as a bearing for the springs.

page_text: I, CHARLES ROBERTS of the firm of Charles Roberts and Company Limited of
The Railway Carriage Works Horbury Junction Wakefield in the County of York
Railway Wagon Manufacturers do hereby declare the nature of my invention for
"IMPROVEMENTS IN BUFFERS FOR RAILWAY WAGONS OR THE LIKE" and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:—
The object of my Invention is to provide a spring buffer for railway wagons or
the like combining in the one device a simple and efficient spring buffer, and a
method of strengthening the buffer ends, and of repairing existing dead buffers
which have been in use for a length of time particularly where the ends have
suffered damaged or become so short as to render it unsafe for men to stand
between the vehicles for the purposes of coupling and uncoupling them. The said
buffers will also prove of great advantage for use on vehicles running on lines
having sharp curves as they are not liable to get buffer locked as so frequently
occurs with the ordinary round buffers.
I will describe my Invention with reference to the accompanying drawing
whereon Figure 1 is a side view and Figure 2 a longitudinal section of a buffer
constructed according to my Invention. Figure 3 is an inside view of the buffer
head.
According to my Invention I first fix a rim band or hoop A of wrought iron or
other metal around the "buffer-end" B. The plunger or buffer head C which is
preferably of the same shape as the "buffer-end" is then placed against the said
end and the buffer casing for "cylinder" D is put in place by being passed partly
'over the "buffer-end" and it is securely fixed to the "buffer-end" preferably by
means of bolts E passed through the said cylinder and "buffer-end" from side to
side and 'secured by nuts. Both the casing for "cylinder" and plunger or buffer
head are formed so that they are secured together when in position in such
manner that the plunger cannot leave the casing or "cylinder" but is capable of
the necessary longitudinal movement therein. In the drawing this is shewn as
being effected by an inward flange d on the 'casing or "cylinder" and an outward
flange c on the plunger. The passage in the casing or "cylinder" through which
the plunger passes is preferably the same shape as the body part of the plunger.
The buffer springs may be made of steel or india rubber of any suitable shape and
may be in any suitable number. I have shewn ring like india rubber springs in
the drawing where they are marked F. In the interior of the buffer head or
plunger are seats or beds to receive the said springs and pins or studs Gare secured
in the 'said head to hold (jointly with the webs c²) the springs in position but these
may be dispensed with. If the springs employed be of the kind shewn or of
other kind which do not extend far enough to bear on the "buffer-end" B, a
bearing piece or lining H (preferably of wood) is used as a bearing for the springs
it having in it recesses hand 2 for the reception of the pins G and webs c²
respectively.
I preferably make the buffer of a square figure to correspond with the shape of
the buffer-end as shewn in the drawings but I do not limit myself to this exact
shape.
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
First A buffer for Railway wagons or the like consisting of a rim band or
hoop fixed round the buffer end and of a casing or "cylinder" which at the part

page_text: passed over the buffer end is of the same shape as the "buffer-end" and is fixed
on the said end and contains a plunger and a spring or springs substantially as
hereinbefore described.
Second-A buffer for railway wagons or the like consisting of a casing or
"cylinder" which at the part passed over the buffer end is of the same shape as
the "buffer-end" and is fixed on the said end and contains a plunger and a spring
or springs substantially as herein before described.
Third: The arrangement or combination of parts constituting the buffer for
railway wagons or the like substantially as herein before described and illustrated
in the accompanying drawings.
