I ALFRED SLATER of Barton Lawn, Gloucester in the County of Gloucester
Manager to the Gloucester Wagon Company Limited do hereby declare the nature of
this Invention to be as follows:-
-
The object of my Invention is to provide a buffer wherein no bolts, pins, cotters,
keys, rivets, rods, screws, loose collars, rings, or such like fastenings, need be used for
securing the plunger to the cylinder. The said fastenings are objectionable as being
very liable to get out of order.
According to my Invention I form the plunger carrying the buffer head with or
without a closed-in or solid base and with a flange or ring projecting outwards from
the base end of the periphery or body of the plunger. The forward end of the cylinder
in which the plunger moves has a ring or flange projecting inwards from its interior
upon which the flange or ring on the plunger bears when it is in its most forward
position. On the outer edge of the forward end of the cylinder there may be made a
projecting ring or flange to give strength to the cylinder and to act as a safety device
for the foot of a person when standing on the buffer cylinder.
As before stated the buffer plunger has a closed-in or solid or open base (preferably
solid) and there is ample wearing surface given to both the projection on the plunger
and that on the cylinder but the plunger need not be longer than, nor indeed as long
as, the cylinder. The internal projection on the cylinder is formed before the plunger
is put in place the cylinder is opened outwards the plunger put in place and then the
cylinder closed in whilst warm. The whole being made in wrought iron or steel and
the surfaces that are usually bored or turned are bored or turned before being put
together.

Improvements in Buffers for Railway Vehicles and the like.
I ALFRED SLATER of Barton Lawn Gloucester in the County of Gloucester
Manager to the Gloucester Wagon Company Limited do hereby declare the nature of
the said Invention 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 buffer wherein no bolts, pins, cotters,
keys, rivets, rods, screws loose collars, rings or such like fastenings, need be used for
securing the plunger to the Cylinder. The said fastenings are objectionable as being
very liable to get out of order.
Figure 1 shews in vertical section a buffer-cylinder and plunger placed together
ready to be permanently attached to each other by closing in the fore-end of the
cylinder as shewn in figure 2.
Figure 3 is an elevation of the completed buffer.
According to my Invention I form the plunger A, carrying the buffer-head, of
wrought iron or steel with, or without, a closed-in, or solid, base a and with a flange
or ring a projecting outwards from the base end of the periphery or body of the
plunger. The cylinder B in which the plunger A moyes is also made of wrought iron
or steel and has a ring or flange projecting inwards from its interior upon which
the flange or ring a² on the plunger A bears when it is in its most forward position.
On the outer edge of the forward end of the cylinder B there may be made a
projecting ring or flange 62 to give strength to the cylinder and to act as a safety
device for the foot of a person when standing on the buffer-cylinder.
As before stated the buffer plunger has either a closed-in or solid, or an open, base;
but preferably a solid one; and there is ample wearing surface given to both the
projection on the plunger and that on the cylinder but the plunger A need not be
longer than, nor indeed as long as the cylinder B. The internal projection on the
cylinder B and the external projection on the plunger A are formed, and the plunger
is turned, and the cylinder is bored on the rubbing surfaces, before the plunger is put
in place. The cylinder is then heated so that it can be opened outwards as shewn in
Figure 1 and the plunger is put in place and then whilst still hot the cylinder is closed
in by hydraulic or other pressure so that the cylinder and plunger are attached
together as shewn in Figures 2 and 3 the buffer, thus made being perfectly solid and'
safe and practically unbreakable.
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
A buffer for railway vehicles and the like constructed substantially as hereinbefore
described with reference to the accompanying Drawings.
Dated this 1st day of May 1888.
