Improvements in Draw Gear and Buffer Devices for Railway and
like Vehicles.
I, HUGO FISCHER VON RÖSLERSTAMM, of Nesselsdorf, Moravia, in the Empire
of Austria-Hungary, 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 :-
This invention relates to coupling and buffer devices for railway and like vehicles
and is illustrated in the accompanying drawing in which
Fig. 1 is a diagrammatic view of the improved device showing three cars
passing a curve.
Fig. 2 is a longitudinal vertical section of a car and
Fig. 3 is a plan of two coupled cars, the platforms being removed.
The draw-bar Z guided in the bottom frame, is connected by vertical pivots D
to the thrust or buffer rods or bars A which project beyond the vehicle, their
extremities occupying the position of side buffers as hitherto used. The connection
between the draw bar and the frame of the vehicle is effected by means of the
spring F.
:
On coupling up several vehicles to form a train, the ends of the thrust or buffer
rods or arms meet, and the said rods or arms are coupled in the usual manner by a
screw or safety coupling; it is possible to apply the usual screw couplings as
employed in Europe as well as the central automatic safety couplings as employed
in America.
By the aid of this device each of the vehicles is, as regards thrust, independent
of the other vehicles in the same way, as such was previously only the case with
regard to the pull or coupling action. Moreover the pivot connection between the
draw bar and the thrust or buffer arms permits vehicles, having axles a considerable
distance apart, to pass the sharpest curves without offering any great resistance,
since the combined coupling and buffer connection adjusts itself, as diagrammatically
illustrated in Figure 1.
As the draw bar has also to receive the thrust, the said bar is made very strong,
aud in order to insure a better guidance of the same, the usual diagonal stays may
be replaced by longitudinal stays L provided with transverse connections W
between which the draw bar is guided. Further to prevent straining of the draw
bar the same may be furnished with buffer springs F which in this case are to be
considered as a substitute for the ordinary buffer springs. The buffer or thrust
rods are provided with a draw bar terminating in a draw hook S, and are stayed
by means of transverse connections Vv (see Figure 3). The buffers as hitherto
used are omitted.
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 :-
A continuous coupling and buffer device for railway vehicles, in which device
thrust or buffer rods or bars A attached to each vehicle are pivotally connected to
the usual draw bar Z; the thrust or buffer rods or bars of the consecutive vehicles
being firmly connected to each other by the couplinge, in order to render the

page_text: vehicles as independent of one another with regard to thrust as was previously
the case with regard to the pull or coupling action, and in order to facilitate the
traversing of curves.
