PROVISIONAL SPECIFICATION..
Improvements in or Connected with Buffers for Railway and other
Carriages.
I, JAMES THORN GOODFELLOW of 14th and Washington Streets, Huntingdon, in
the County of Huntingdon and State of Pennsylvania, United States of America,
Engineer, do hereby declare the nature of this invention to be as follows:-
My invention refers to means, as hereafter described for applying buffers to
railway and other carriages, where the platforms or frames of same are made of
tubular metal such as those described in the specification of patent No. 14,86384,
and in such manner that buffers of ordinary construction as usually applied to both
sides of the carriage can be utilized therewith.
According to my invention the central pairs of the longitudinal tubes are utilized
as guides for sliding jaw forks on or connected with ordinary elliptic plate or leaf
spring or springs the said jaw forks, springs and. parts connected therewith being
situate between the longitudinal tubes, so that one set of tubes is above, and the other
below, the aforesaid parts. The elliptic plate or leaf spring or springs is or are
connected by a tension rod or rods to the end sill or front framework of the carriage.
The plunger rods or spindles of the side buffers are provided with plates guided by the
longitudinal tubes and in such manner that on the side buffers being compressed,
the plates slide on the longitudinal tubes (between which the springs are arranged)
the tension on the spring and on the tension rod, being thereby increased the jaw
forks moving in corresponding relation thereto.
;
The tension bar may be utilized as a draw bar by modifying the arrangement
of the slide plates, and other descriptions of springs may be used than those before
referred to..
Dated this or any of Depremo 1000.

COMPLETE SPECIFICATION.
Improvements in or Connected with Buffers for Railway and other
Carriages.
I, JAMES THORN GOODFELLOW of 14th and Washington Streets, Huntingdon,
in the County of Huntingdon, and State of Pennsylvania, United States of America,
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:
My invention refers to means as hereafter described for applying buffers to
railway and other carriages where the platforms or frames of same are made of
tubular metal such as those described in the specification of patent No. 14863 of
1884, and in such manner that buffers of ordinary construction as usually applied
to both sides of the carriage can be utilized therewith.
My invention will be clearly understood by the following description having
reference to the accompanying drawings.
Figure 1 is a vertical longitudinal section on the line A B of Figure 2 which latter
is a plan of one end of the under frame of so much of my tubular trussed framed car
shewing the side buffers applied thereto according to my present invention as will be
necessary to explain same.
Figure 3 is an end view of the car shewn at Figures 1 and 2.

page_text: Figure 4 is a longitudinal vertical elevation of the end portion of the car frame.
Figure 5 is a transverse vertical section on the line CD of Figure 2.
Figure 6 is a longitudinal' vertical sectional view drawn to a larger scale than the
previous, figures showing the slide blocks' between which the "buffer" spring is
carried, and
'
Figure 7 is a vertical cross section of Figure 6.
Siniilar letters of reference refer to like parts in all the figures.
According to my invention the central pairs of longitudinal tubes are utilized as
guides for ordinary plate or elliptic plate or leaf spring or springs.
A Aare the two central pairs, and A A the two outer pairs of tubes, B'is the
end sill, is the transom beam, D D. are the buffer discs, EE are the buffer rods,
and FF the guide boxes through which the rods: E E slide and. by which they are
guided.
The buffer rods are provided with bearers E' E' at their back ends, which bear on
the ends of the elliptic or leaf spring G situated: between the longitudinal tubes A' A¹
so that one set of tubes is above and the other set of tubes is below the spring, and
at this part of the tubes A¹ A' slide pieces are provided marked H and shewn clearly
at Figures 6 and 7, and it is between these slide pieces that the spring G is carried;
all wear is thus taken off the tubes.
The spring is further carried by two horizontal longitudinal' guiding tubes I I
extending between the end sill and the transom beam.
The spring or springs. may be connected by a tension rod or rods to the end sill
of the carriage, but I generally prefer as shewn, to utilize the tension bar as a
draw bar..
.
K is the tension bar which passes through the end sill. B and is provided with
a. draw hook K!.
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:-
1st. In buffers for railway and other carriages, the combination with the tubular
trussed framework composed of the longitudinal tubes A A A' A', the end sills B,
the transom C and parts connected therewith, of the buffing arrangement composed
of the discs D, rods E, guide boxes F, spring or springs G, tension draw rod K,
all substantially as and for the purposes herein described with reference to the
accompanying drawings.
2nd. In buffing and draw gear as applied to carriages having tubular trussed
under framing, the combination and arrangement of parts consisting of the discs D,
rods E, bearers F¹, guide boxes F; spring or springs G, tension rod K guided
between tubes A' A' provided with slide plates H and tubes i I as set forth.
