PROVISIONAL SPECIFICATION.
Improvements in Central Buffer and Coupling Apparatus for Railway
and like Vehicles.
We, ALFRED EDMOND ADIE, Assoc. M. Inst.C.E., Engineer-in-Chief and Manager
of the Howrah-Amta, Howrah-Sheakhalla, and Ranaghat-Krishnagar Light
Railways, in the Province of Bengal, India, and WILLIAM NAYLOR, Locomotive
and Carriage Foreman of the above said railways, do hereby declare the nature
of this invention to be as follows:-
This invention relates to central buffers whatever their coupling, such as
vertical hook with horizontal pin, or horizontal link with vertical pin, and its
object is to provide an effective and simple central draw-buffer with either hook
and pin or link and pin screw coupling, suitable for central buffers of any gauge
of railway or tramway as we shall now describe with reference to the accom-
panying illustrative drawings wherein rigs. 1 and 2 show respectively in side
elevation and end view a central buffer with a hook coupling according to this
invention, and Figs. 3 and 4 show respectively in side elevation and horizontal
section, a similar buffer but with a link coupling according to this invention.
In carrying the invention into effect, elongated pin holes B, 13, are in each
arrangement made in the buffer A, through which holes the coupling or draw-
pin C is inserted.
On the buffer A and placed between the head of the buffer and a moveable
lug D, which is fixed on the shoulder of the buffer, is a tightening screw E fitted
with a turning handle E¹, and on the screw E is fitted a traversing nut F.
The coupling or draw pin C is coupled to the traversing nut F by means of two
coupling plates G, G which, when the traversing nut F is moved in either
direction, draws the pin in a corresponding direction. Guide lugs H, H are
formed on the buffer against which the coupling plates slide and by which they
are kept in position. Washers I and split pins J serve to keep the coupling
plates G secure in their respective positions. In Fig. 1 K is the coupling hook;
in Figs. 3 and 4, L is a coupling link.

page_text: Railways, in the Province of Bengal, India, and WILLIAM NAYLOR, Locomotive
and Carriage Foreman of the above said railways, 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, thereof
that is to say:-
The invention relates to central buffers of railways or tramways which have for
their coupling either the vertical hook with horizontal pin, or the horizontal
link with vertical pin; and its object is to produce an effective and simple central
buffer with either link and pin, or hook and pin screw coupling suitable for any
gauge of railway or tramway.
In order that the invention and the means by which it is to be carried into
practical effect may be thoroughly understood. We will now describe it in detail
referring in so doing to the accompanying drawings which are to be taken as
part of the specification and read therewith.
Fig. 1 is a side elevation of the gear as applied to a hook coupling.
Fig. 2 is an end elevation of the same.
Fig. 3 is a plan of the gear as applied to a link coupling.
Fig. 4 is an elevation of the same.
All the figures illustrate the position which the respective parts occupy in
carrying the invention into effect.
A is the body of a central buffer for railways or tramways the original pin
hole B of which is elongated so as to allow the coupling pin to travel in a lateral.
direction, either in tightening up or slacking off the coupling. C is the draw pin.
or coupling pin to which is attached two coupling plates G, G, these coupling
plates are attached to the coupling pin C and to a traversing nut F and held
in their respective positions by washers and pins. The traversing nut F is
fitted on to a turn screw E which is provided with a handle, and fixed between
the inside face of the buffer head, and a lug D bolted on to the shoulder of the
buffer. The lug D is recessed; one end of the screw E, turning inside this recess,
the other end of the screw being fitted inside and against the buffer head. The
whole strain of the draw-gear is against the buffer head.
Square lugs H. H, are fitted or forged on the body of the buffer, for the purpose
of keeping the coupling plates in position and against which lugs the plates travel
in a lateral direction.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
The combination of two coupling plates or links coupled to the coupling pin,
and a traversing nut, a screw placed between the inside face of the buffer and a
movable lug bolted on to the shoulder of the buffer, two square lugs fixed on to
the body of the buffer against which the coupling plates slide in a lateral position,
on the screw being turned in either direction. Washers and pins to keep the
respective parts in their position substantially as described and illustrated.
