page_text: manner the same is to De performed, to be particularly described and ascertamea
in and by the following statement :-
This invention-relates to couplings of the kind described in the Specification of
my prior application for Patent No. 8060 dated the 23rd day of April 1895 and
has more especially for its object to devise means for enabling such couplings to
be readily applied to railway vehicles of other constructions than those indicated
in the aforesaid Specification.
In order that my said invention may be fully understood and readily carried into
effect, I will proceed to describe the same with reference to the accompanying.
drawings in which
Figure 1 is a plan,
Figure 2 a longitudinal section, and
Figure 3 an end view shewing a portion of the under-frame of a railway vehicle
wherein laminated springs are employed in connection-with the buffers and the
draw-bars.
Figure 4 is a similar view to Figure 2 but shews a portion of a railway
vehicle of the kind wherein rubber springs are employed instead of laminated
springs.
AA are the longitudinal and transverse beams of the under-frame; B the draw
bar; C the buffers; D the spring; and E the coupling which latter is in every
case indicated in dotted lines.
In the arrangement shewn by Figures 1, 2 and 3 the draw-bar comprises a
central rod provided at its ends with yoke pieces which connect the said rod
with intermediate rods 6, the latter being in their turn connected to hooked bars bª
by means of pairs of links . The buffers C slide in sockets carried by the end
beams of the under-frame and are provided with caps c at their inner extremities
against which the ends of the spring D bears as is well understood. The central
portion of the spring D is embraced by a band d which lies in the space existing
between the links 6. There is a space left between the shoulder 6x of the hook b
and the end beam of the underframe. A similar space is also left between the
inner end of the hooked bar 63 and the band d, and the inner ends of the links b*
are slotted where the connecting pins 66 pass through them. In this manner ample
play is left for the draw-bar to move inwards when the couplings of a pair of
vehicles meet, or to move outwards when a pull is exerted upon the draw-bar.
In order to securely attach the coupling E to the hooked bar 63 and at the same
time permit of its movement in a horizontal plane, I provide a bent arm or bracket 66
which is bolted, at its inner end, to the draw bar by the bolt . The front end of
this bracket passes through a socket 68 bolted to the underside of the aforesaid end
beam. The bracket serves to give extra support to the coupling and is free to
move longitudinally in this socket so as to partake of the to and fro movements of
the coupling and draw-bar. The coupling is connected to the draw bar by a
bolt 6 passing vertically through the hooked bar 6 and the bracket 6. The hole
in the hooked-bar through which this bolt passes is situated at a sufficient distance
away from the beak of the hook 6 to ensure that said bolt can be readily removed
23

hook is welded in one piece with the bar b³.
In the arrangement illustrated at Figure 4 like letters of reference are employed
to indicate similar parts to those already described with respect to the preceding
figures. In this case the draw bar B consists of a central rod connected to the 5
two hooked bars 63 by means of the yoke pieces b¹. The hooked bars are formed
in one piece with the bars 62: Instead of a laminated spring, a rubber spring D is
shewn mounted on the bar 62 between the two collars d' d², one of which collars,
viz. d', hears against the transverse beam of the under frame. d³ is a key for
keeping the other collar d² in position upon the draw-bar...In other respects this
arrangement is similar to the one already described.
It will be observed that the construction of the draw-bar, renders it compressible
but non-extensible.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The herein described means for enabling my coupling to be applied to railway
vehicles of the kind hereinbefore referred to.
B
2. The construction of the draw bar of a railway vehicle, substantially as
described with reference to Figures 1, 2 and 3 or to Figure 4 of the accompanying
drawings and for the purpose specified.
