Improvements in and relating to Couplings for Railway Vehicles.
I, JOSEPH SINCLAIR FAIRFAX, Patent Agent and Consulting Engineer, of
433 Strand, in the County of London, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and acertained in and by the following statement :-
This invention, as communicated to me from abroad, relates to the couplings
used in connecting railway vehicles together.
The invention is described with reference to the accompanying drawings, in
which
Fig. 1 is an elevation of a buffer head, coupling link, and coupling pin with
spring, all ready for being suitably secured to a railway vehicle; Fig. 2 is a plan of
the same; and Fig. 3 is a back view and Fig. 4 a side view of the coupling pin
with the spring removed.
In the drawings a is a buffer head having a wide mouth and inner chamber as
indicated by the dotted lines in Figs. 1 and 2. At the back end of the buffer head
is an extension b with a vertical hole c for connection to the draw bar, but it is to
be noted that I do not confine myself to this particular feature as any suitable
means for attaching the buffer head to the draw bar, or to the vehicle may be used
without affecting the nature of the invention. An ordinary elongated coupling
link d is shown in position in Figs. 1 and 2, with one end inserted in the mouth of
the buffer head a, and passing into the inner chamber where it is held by a peculiar
hook shaped head of a vertical pin e. The pine is fitted into a vertical hole in the
buffer head and is provided with a slight projecting head or flange e¹ placed
horizontally on each side of the top of the pin, which fits into a corresponding
recess or seat on the top of the buffer, to keep the pin in position. The pin e has
also a forward projection e' of hook form, with a bevelled nose adapted to slide
over the end of the coupling link d, when the latter is forced into the inner chamber
of the buffer mouth; thus lifting the pin e as the bevelled nose slides over the link
and holding the latter by the hook portion e², as shown in Fig. 1. A spiral spring f,
surrounds the pin e, and re-acting against a pin and collar at the bottom, holds the
pin firmly in position. A shackle g is pivoted to the top of the pin e, whereby it is
lifted by any suitable means when it is desired to uncouple the link d.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what
I claim is ;-
1. A coupling for railway vehicles having in combination a buffer head a having
a wide mouth and inner chamber, a vertical pine having a forward projecting
hook and bevelled nose with means e¹ and spring ƒ for seating and retaining
the said pin in position, means y for raising the pin e, and a coupling link d,
substantially as and for the purpose herein described.
2. In a coupling, a hook pin with a vertical stem head e¹, projecting hooks,
and bevelled nose e', combined with means g for lifting the said pin, substantially
as and for the purpose herein described.
Dated this 17th day of August 1893.
