Improvements in Railway and other Buffers.
FREDERIC BARRY STANTON Engineer Mansion House Chambers 11 Queen Victoria
Street London, E.C. in the County of Middlesex do hereby declare the nature of this
invention to be as follows:-
Improvements in and relating to Railway and other Buffers.
My Invention relates to Railway & other buffers and is designed to improve their
construction and thereby imparts to them strength efficiency and durability and at
the same time to facilitate the removal of the plunger or Rod from and its
replacement in the buffer case or cylinder and also to reduce the cost of
production.
In some buffers as heretofore constructed, if the plunger is strained or broken it
cannot be withdrawn without considerable difficulty and injury to the buffer and
requires skilled labor to replace the damaged parts. By my invention I obtain the
security of a solid collar and great facility for the removal of the Rod or plunger without
in the least damaging any of the parts and the work can be performed by
ordinary unskilled labourers and without the necessity of being sent into the
workshops.
I adopt the following means of securing the plunger inside the cylinder as
preferable to any of the forms yet adopted and particularly in preference to any form
of "Lock Nutwhich almost invariably damage the threads or put on such an amount
of work that a man with ordinary appliances cannot perform the necessary operation
I also obviate the necessity of using set pins or any other intricate mode of securing
the parts.

Against this Clip Washer D the spring presses and keeps it up to its work when it
will be seen that the screwed washers cannot become loose or unscrewed by the action
of the turning of the Rod or plunger when in work.
Figure 2 (8) shows an alternate plan which may be used when desired or when
there is insufficient room for the cars D¹ on washer D in figure 1. In this case one
or more screwed washers may be used and fixed by means of the plate K having fixed
lugs or projections L thereon and corresponding holes to these projections in the
screwed washer to receive them. In this case I make the part of the Rod E just past
the Screwed Washer M. square or unequal section N by planing off one or more sides
of the rod or otherwise I then make the hole in the Lock Washer K square or unequal
shape to suit the shape of that part of the Rod E that it passes onto when close up to
the Screwed Washer M then the spring presses against the Lock Washer K & keeps
up to its work and the Screwed Washer cannot become unscrewed whilst in work as
before described.

convenient the threads may be both right hand or both left hand but of different
pitch in either case however the Clip Washer D) or the Lock Washer K. is
used.

with the Clip Washer D with cars D₁ with sq. or unequal hole to fit the Rod E
similarly shaped as before described or with the Lock Washer K.

to the screwed washer by means of set Screws G (or otherwise), tapped into the
Screwed Washer but I prefer the Stud Washer as before described as being more
simple more easily fixed & cheaper.

page_text: I, FREDERIC BARRY STANTON, Engineer of No. 11 Queen Victoria Street,
London, E.C. in the County of Middlesex 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 :-
My invention relates to Railway and other buffers and is designed to improve their
construction and thereby imparts to them strength efficiency and durability and at
the same time to facilitate the removal of the plunger or Rod from and its
replacement in the buffer Case or Cylinder and also to reduce the cost of
production.
In some buffers as heretofore constructed, if the plunger is strained or broken it
cannot be withdrawn without considerable difficulty and injury to the buffer and
requires skilled labor to replace the damaged parts.
By my invention I obtain the security of a Solid Collar and great facility for the
removal of the Rod or plunger without in the least damaging any of the parts and the
work can be performed by ordinary unskilled labourers and without the necessity of
being sent into the workshops.
I adopt the following means of securing the plunger inside the Cylinder as
preferable to any
of the forms yet adopted and particularly in preference to any form
of "Lock Nuts" which almost invariably damage the threads or put on such an
amount of work that a man with ordinary appliances cannot perforin the necessary
operation.
I also obviate the necessity of using set pins or any other intricate mode of securing
the parts.
Figures 1 & 12 shew a longitudinal section through the centre.
A is the plunger
or Rod working through the Cylinder or Case B. The cylinder may be of any form
& of any suitable material is a Screwed Washer with right hand thread Ca
Screwed Washer with left hand thread (or vice-versa) screwed up so that the sides of
the Washers come flush when together, these screwed washers may be square oblong
Hexagonal Round with flats or any suitable shape so that there may be surfaces to
suit & fit the ears D¹ of the Clip Washer. D D is a Washer of Steel or other suitable
material with cars 1) bent or so made as to clip the two Screwed Washers after being
passed over the Rod E, against this Clip Washer D the spring presses & keeps it up to
its work when it will be seen that the Screwed Washers cannot become loose or
unscrewed by the action of the turning of the Rod or plunger when in work, as before
described.
If preferred the Clip Washer may be replaced by a cap, taking at once all the
sides of the Screwed Washers but this being expensive I prefer the Clip Washer with
one two or more ears.

Figures 3 & 15 another modification will be found here wherein if more
convenient the threads may be both right hand or both left hand but of different
pitch in either case however the Clip Washer D-Cap-or Lock Washer K-
is used.
Figures 4. 6. 10 shew a plan where one Screwed Washer is used in conjunction
with the before mentioned securing Washers or Cap. In this case I put an unequal
shaped hole in the Washers vizt. Hexagonal square or with any other shape
excepting Round and I so shape the plunger rod E to conform to the same shape
as in the Washers thus forming a permanent & secure stop.
Figures 5 & 14 shew a plan where if preferred Lock Washer K may be secured to
the Screwed Washer by means of set screws or otherwise tapped into the screwed
Washer but I prefer the Stud Washer as being more simple & efficient &
cheaper.
Figure 6 shews a plan of fig. 4 in section.
Figure 7 shews plan of fig. 3 in section.
Figure 8 shews enlarged view of fig. 2.
Figure 9 is plan of fig. 8 in section.
Figure 10 is enlarged view of fig. 4 in section.
Figure 11 is plan in section of fig. 10.
Figure 12 is an enlarged view of fig. 1.
Figure 13 is plan in section of fig. 12.
Figure 14 is enlarged plan of fig. 5.
Figure 15 is enlarged plan of fig. 3.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is performed I declare that what I
claim is
An improvement in the mode of fastening the plunger (or Rod) of a Railway
(or other) buffer in the Cylinder (or case) by means of a clip or lock Washer or Cap
in combination with Screwed Washer or Washers, as shewn by the various figures in
drawing left with the Provisional Specification as above described as and for the
purpose specified.
Dated this the 12th day of September 1888.
