Year: 1867

page_text: LETTERS PATENT to George Wilson, of the Cyclops Steel and Iron
Works, Sheffield, in the County, of York, for the Invention of "Ax
IMPROVEMENT IN THE CONSTRUCTION OF BUFFERS."
PROVISIONAL SPECIFICATION left by the said George Wilson at the
Office of the Commissioners of Patents, with his Petition, on the 6th May
1867:
I, GEORGE WILSON, of the Cyclops Steel and Iron Works, Sheffield, in
the County of York, do hereby declare the nature of the said Invention for
AN IMPROVEMENT IN THE CONSTRUCTION OF BUFFERS," to be as follows:-
This improvement relates to the means of retaining the plunger of the
buffer in its case. The inner end of the hollow plunger I close by a rebated
or flanged washer plate, the outside diameter of which exceeds the diameter.
of the plunger, and is intended to rest against a shoulder or projection formed
in the case in which the plunger slides. The washer is retained in position
by means of a central bolt which is rivetted into the washer at one end and
into the plunger head at its other end; or the central bolt may be screwed
into the washer or plunger head if required; or the washer plate may be.
fastened to the end of an ordinary plunger by means of set screws. The buffer.
in other respects is similar to ordinary buffers.

-TO-ALL-TO-WHOM-THESE PRESENTS SHALL COME, I, GEORGE
WILSON,-of-the-Cyclops-Steel and Iron Works, Sheffield, in the County of
York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of May, in the year of our Lord One
thousand eight hundred and sixty-seven, in the thirtieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said George Wilson, Her special licence that I, the said George
Wilson, my executors, administrators, and-assigns, or such others as I, the
said George Wilson, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "AN IMPROVEMENT
IN THE CONSTRUCTION OF BUFFERS," upon the condition (amongst others) that
I, the said George Wilson, my executors or administrators, by an instru-
ment in writing under my, or their, or one of their hands and seals, should
particularly describe and ascertain the nature of the said Invention, and in
what manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said George Wilson, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement, reference being had to the Drawing hereunto annexed, and to the
letters and figures marked thereon (that is to say) :-
:-
This Invention relates to certain means of retaining the plunger of the
buffer of railway carriages in its case. In order to effect this in a simple and
efficient manner, I construct the buffer in the manner shewn in the accom-
panying Drawing, wherein Fig. 1 is a longitudinal section, and Fig. 2 a cross
section of the improved buffer.
A, A, is the fixed case containing the usual coiled spring B, and in which the
plunger C works as usual. The inner end of the hollow plunger C I close by
a rebated or flanged washer or disc plate D, the outside diameter of which
exceeds the diameter of the plunger sufficiently to form a shoulder that will
2.

page_text: rest against a shoulder or projection E formed in the case A in which the
plunger slides by increasing the thickness of the case near its outer end. The
plate D is retained in position on the end of the plunger by means of a central
bolt F, which is rivetted at one end into the plate and at the other end into
the plunger head; or the central bolt may be screwed into the plate D and
plunger head if required. Instead of the above arrangement the washer or
plate D may be fastened to the end of an ordinary plunger by means of set
screws and made to bear against the shoulder of the fixed case A ; I prefer,
however, the plan shewn in the Drawing. The buffer in other respects is
similar to ordinary buffers.
Having now set forth the nature of my Invention of "An Improvement in.
the Construction of Buffers," and explained the manner of carrying the same
into effect, I wish it to be understood that under the above in part recited
Letters Patent I claim, the means, above described, for retaining the plungers
of buffers in their cases.
In witness whereof, I, the said George Wilson, have hereunto set my
hand and seal, the Fifth day of November, in the year of our Lord One
thousand eight hundred and sixty-seven.
