PROVISIONAL SPECIFICATION.
Improved Combined Buffer and Automatic Coupling for Railway and
Tramway Rolling Stock.
We, ANDREW SCLANDERS NELSON, Managing Director of the Firm of Hurst,
Nelson & Co., Limited, The Glasgow Rolling Stock and Plant Works, Mother-
well, in the County of Lanark, and ALBERT SIEWART, Engineer, with said firm,
do hereby declare the nature of this invention to be as follows:-
The object of this invention is to provide an inexpensive combined automatic
coupling-buffer by means of which the coupling together of two vehicles may
be effected by simply pushing them together, the vehicles being uncoupled when
required by raising a catch or coupling hook.
The invention consists of a bell mouthed buffer provided with a catch or coup-
ling hook which engages in a loose link or bar. The coupling hook is free to
work upon a pin passing through the sides of the buffer head. The motion of
the hook may be controlled by means of a spring of suitable form, such as a
rat-trap spring or by other means having the same end in view. The front
portion of the look is formed so as to bear against a portion of the top of the
buffer head, thus relieving the pin from undue strain. The back portion of the
coupling part of the hook is formed so that the coupling link cannot move back-
wards more than desired, so as to force the ink to raise the hook in the oppo-
site buffer when the vehicles are pushed together. When the hook is raised
by means of the link, the link passes underneath the point of the hook which
immediately falls into position and coupling is effected, the controlling spring
or other apparatus keeping the hook from rising until lifted up intentionally.
The top front end of the hook is formed into an eye for the purpose of attach-
ing a chain or other suitable apparatus for the purpose of raising the hook
when desired to release the link and thus uncouple the vehicles. When not
required for coupling the hook may be kept out of the engaging position by
means of a pin or a spring suitably arranged. The coupling link may be of
the usual form or may be made of a flat bar with a suitable hole in each end.
The buffer head and draw bar may be made in one piece or the head may be
made separate for attaching to the buffing and draw bar by any suitable means.

page_text: well, in the County of Lanark, and ALBERT STEWART, Engineer, with said firm,
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:―
The object of this invention is to provide an inexpensive combined automatic
coupling-buffer by means of which the coupling together of two
two vehicles may
be effected by simply pushing them together, the vehicles being uncoupled when
required by raising a catch or coupling, hook.
The invention is illustrated by the accompanying drawings, Figure 1 being
à longitudinal vertical section of the combined buffer and automatic coupling,
Figure 2 an end view, and Figure 3 a plan of the same.
""
The invention consists of a bell mouthed buffer A provided with a catch or
coupling hook B which engages in a loose link or bar C. The coupling hook B
is free to work upon a pin D passing through the sides of the buffer head A.
The motion of the hook B may be controlled by means of a spring E of suitable
form, such as a rat-trap, spring or by other means having the same end in view,
The front portion of the hook B is formed so as to bear against por-
tion of the top of the buffer head A thus relieving the pin D from undue strain.
The back portion of the coupling part of the hook B is formed so that the
coupling link or bar C cannot move backwards more than desired, so as to force
the link C to raise the hook in the opposite buffer when the vehicles are pushed
together. When the hook B is raised by means of the link C, the link passes
underneath the point of the hook B which immediately falls into position and
coupling is effected, the controlling spring E or other apparatus keeping the
hook from rising until lifted up intentionally. The top front end of the hook B
is formed into an eye B' for the attachment of a chain For other suitable ap-
paratus for the purpose of raising the hook B when desired to release the link C
and thus uncoupling the vehicles. When not required for coupling, the hook B
inay be kept out of the engaging position by means of a pin or a spring suitably
arranged. The coupling link C inay be of the usual form or may be made of
à flat bar with a suitable hole in each end. The buffer head A and draw bar A¹
inay be made in one piece or the head A may be made separate for attaching to
the buffing and draw bar A¹ by any suitable means.
Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed, we declare that what
we claim is: :-
1. A combined buffer and automatic coupling for railway and tramway rolling
stock, the parts of which are constructed, combined and arranged to be operated;
substantially as described.
2. In railway and tramway carriages or wagons, the combination with a bell-
mouthed buffer head formed on or secured to the buffer rod, of a pivoted hook
adapted to be raised to couple with the adjacent carriage by the action upon
its free end of a coupling link, said hook being returned to its normal position
by a spring, substantially as described.
