a are the buffer rods located within the frame and connected by cross pieces b.
In these cross pieces are supported the brake-rods d and draw-bars c.
When the buffers are made to yield on coming into contact, they mutually
impart their inward motion to the cross pieces and hence to the brake rods and
draw-bars supported in same; when the pressure on the buffers is released, they
return automatically, along with the brake-rods and draw-bars, to their original
position.
The brake-rod d, when pressed inwards, engages, by means of a cam or tappet d'
with the levers and brake-shoes, causing an automatic application of the latter on
the wheels, the draw-bar c being also simultaneously forced inwards in the same
ratio by the cross piece bengaging with a cam with which said draw-bar is
provided, so that the coupling is constantly kept in a stretched position. Said
draw-bar returns automatically to its original position with the buffers and cross
pieces when released.
The brake-rod d with cam or tappet d¹ can, as will be seen from the drawing,
consist of two short rods supported at their outer ends in the centre of the cross
piece b underneath the draw-bar c and centrally connected by a coupling sleeve h.
Said brake-rod can, however, also consist of several rods of any desired size, having
tappets or cams, located at any suitable place, and can be arranged to operate any
kind of brake and in any way desired.
The draw-bar c can consist of two parts centrally connected and whose inward
and reverse motions are effected automatically by the cross pieces b and springs
at cas shown in the drawing. The draw bars can also be constructed in various
other ways or consist of several parts so as to slide together and effect the purpose
of keeping the coupling stretched.
In order to give the draw-bar c more elasticity and further minimise the strain
on the cross piece and end beam of the vehicle, said draw-bar is provided with a
spring device c which acts on the cam end e of the draw-bar.
In order that the brake may be thrown out of gear when not required to act, an
arrangement is provided whereby the cams on the brake rods can be turned by
Paine 77

page_text: means of worm wheel mechanism operated by a leverf preferably located on the
sides of the vehicle about the centre, in such way that, when the brake rod is
forced inwards with the cross piece, the cams on same do not engage with the
brake levers.
This arrangement for throwing the brake rods in and out of gear can be modified
as desired and, if necessary, arranged so as to be under the control of the persons in
charge of the locomotive.
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. A buffer-brake and improved draw-bar for railway vehicles characterized
by the arrangement of a movable and revolvable rod or rods d acted on by the
buffer-rods a in such manner, that, by means of tappets or cams, brake-shoes of
any description can be caused to press against the wheel-tyres, the coupling
being meanwhile kept stretched in all positions of the train substantially as
set forth.
2. In a buffer-brake and improved draw-bar, the draw-bar c in two or more parts,
centrally or otherwise connected, or arranged in parts sliding together, in com-
bination with the cross pieces b, springs c¹, springs c³ and connecting sleeve /
substantially as described.
