IMPROVEMENTS IN THE CONSTRUCTION OF SPRING BUFFERS
Year: 1885

page_text: I ALEXANDER WILSON of the Cyclops Steel and Iron Works, Sheffield in the
County of York, Engineer do hereby declare the nature of my invention for
"IMPROVEMENTS IN THE CONSTRUCTION OF SPRING BUFFERS" to be follows:-
This invention relates to the construction of spring buffers for railway vehicles
of every description. These buffers are made entirely of wrought iron and steel
and are consequently lighter and more durable than ordinary buffers; they are
cheap and simple in construction.
The box or case is formed of wrought iron plate bent and welded in a conical
form; it is afterwards swaged down at the smaller end to form the cylinder to
receive the buffer spindle and to form an internal shoulder to serve as an abutment
for the collar or washer upon which the spring thrusts. The case is flanged at the
other end to be secured by bolts or rivets to a base plate.
The base plate may be made any shape to suit the position in which it has to be
fixed, to the centre of it a strong wrought iron rod is welded for the purpose of
securing the plunger in position.
The plunger is made with a hollow spindle into which the rod enters. The
spindle is also cut or slit at the top and bottom to receive a steel cotter which is
inserted through the rod and to allow the spindle to slide along the rod the
necessary distance without being interfered with by the cotter. This cotter is
formed with a head at the top and a strong ring is inserted through it at the bottom
to prevent it getting out of position.
The buffer may receive any kind of spring.
:
There is great advantage of making the case as described without any bush or
auxiliary part.
:
The collar retains the spring in its position without any strain on the plunger.
Examination of the buffer can be made with great facility the fastening of the
plunger in its position in the box is exposed to view and any disarrangement is
seen at once.
The buffer may with facility be taken to pieces for repair. When the cotter is
taken out the plunger can be removed without disturbing the spring or if the
spring be damaged it can be removed by slackening the bolts in the base plate..
The whole of the parts can be made to templates and interchangeable so that a
few duplicate parts may be kept at any depot for almost instant repairs.

I ALEXANDER WILSON of the Cyclops Steel and Iron Works, Sheffield in the
County of York Engineer 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 :—
This Invention relates to the construction of spring buffers for railway vehicles
of every description. These buffers are made entirely of wrought iron and steel
and are consequently lighter and more durable than ordinary buffers; they are
cheap and simple in construction.
The box or case is formed of wrought iron plate bent and welded in a conical
form; it is afterwards swaged down at the smaller end to form the cylinder to
receive the buffer spindle and to form an internal shoulder to serve as an abutment
for the collar or washer upon which the spring thrusts. The case is flanged at the
other end to be secured by bolts or rivets to a base plate.
The base plate may be made any shape to suit the position in which has to be
fixed, to the centre of it a strong wrought iron rod is welded for the purpose of
securing the plunger in position.
The plunger is made with a hollow spindle into which the rod enters. The
spindle is also cut or slit at the top and bottom to receive a steel cotter which is
inserted through the rod and to allow the spindle to slide along the rod the
necessary distance without being interfered with by the cotter. This cotter is
formed with a head at the top and a strong ring is inserted through it at the bottom
to prevent it getting out of position.
The buffer may receive any kind of spring.
There is great advantage in making the case as described without any bush or
auxiliary part.
The collar retains the spring in its position without any strain on the plunger.
Examination of the buffer can be made with great facility; the fastening of the
plunger in its position in the box is exposed to view and any disarrangement is
seen at once.
The buffer may with facility be taken to pieces for repair. When the cotter is
taken out the plunger can be removed without disturbing the spring or if the
spring be damaged it can be removed by slackening the bolts in the base plate.
The whole of the parts can be made to templates and interchangeable so that a
few duplicate parts may be kept at any depot for almost instant repairs.
In order that my said invention may be fully understood and readily carried
into effect. I will proceed to describe the drawing hereunto annexed.

page_text: b, is the base plate fixed by bolts to the flange of the box or case. c is a round
bar or spindle welded to the base plate and passing centrally through the case.
d is a washer loose on the spindle. e is a spring confined between the base plate
and the washer d; the spring causes the washer to abut against the shoulder
produced by swaging down the part at of the box or case. f is the plunger and fi
is the buffer head formed of a piece with it. The plunger f is hollow and it fits
easily over the spindle; its end abuts on the washer d.
The plunger is slotted at f* fx to receive the key g which also passes through
the spindle by a closely fitting hole or key way. The key at one end has a head
which is unable to pass through the key way and at the other end it receives the
ring h. This ring is formed of stout wire and it is inserted and bent to form when
the plunger is in its place. The slots f*f* are of such a length as to allow for
the requisite play of the plunger; when the plunger is forced in the washer is
displaced from its seat and the spring is further compressed.
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:
1. My improved spring buffer substantially as described.
2. In a spring buffer the combination of the parts a. b. c and d forming the spring
box substantially as described.
