page_text: By my invention -
connect my coupling to the draw Hook by means of a link
instead of by a shackle and pin. To enable me to do this, I have two arrangements
both of which are shown in the accompanying drawings,.
•
Figures 1 and 2 showing the arrangement I generally prefer and
Figures 3 and 4 a modification in which, the drawbook is made séparate from the
draw bar.
In the arrangement shown in figures i od 2T form the draw hook A
with the usual hole a passing transversely, through it and provided with a narrow
opening or open slot a at the top. The link B of the coupling is provided with
two-flats opposite one another which enable, the link if properly manipulated to
drop through the opening or slot a into the hole a. Figure 1 shows the position
the link should be put in for passing it through the slot. C is a sleeve or ferrule
which is slipped over the flats of the links B.when the latter is in the position
shown in Figure, 2 and, closed in or hammered down on these flats, thereby
preventing the removal of the link. The sleeve in fact covers the flats
and
d prevents the coupling being taken out without cutting the sleeve or ferrule
to pieces.
I do not however limit myself to the exact arrangement of the sleeve or ferrule C,
as: a nut, plate or any other suitable device may be employed for covering or
filling up the flats 6 so as to prevent the coupling link being removed through the
slot. Moreover I do not limit myself to forming the link with flats b'as instead of
a flattened portion, the link may be otherwise reduced in size at one or more parts
so as to enable it to pass through the blot.

In the other arrangement shown in Figures 3 and 4, T' form the shauk or neck A¹
of the drawhook A separate from the draw bar Band, with a jaw or open slöt A³,
in such a way that the link B of the coupling can be slipped through this jaw
or slot into a hole in the hook. The end B of the draw bar or pin is formed
so as to exactly fit the jaw A of the book and is fastened thereto by rivets D.
pins' or the 'like so that the link B cannot possibly be stolen without taking the
draw gear to pieces. To remove the coupling, it is necessary to slacken the
draw bar, pull the look out of its place in the headstock of the vehicle and take
out the pins or rivets.D: This will enable the hook A to be disconnected from the
rod B and the coupling can then be removed.

1. The improvement in coupling apparatus for railway vehicles, which consists
in forming the hole in the draw hook in which lies the coupling link, with a
narrow opening or slot such as aly and the coupling, link with a flattened or reduced
portion, which admits of the links being passed at the reduced part only through
the slot into the hole in the draw hook, in combination with a ferrule or sleeve
on the link, which, when the link is in place in the hook, can.
the flattened or reduced portion and hammered down thereon to prevent the link
be slipped on to
being removed through the slot, whereby the: link is locked in place in the bole
in the draw hook, and from which it cannot be extracted except by cutting off the
sleeves or ferrules from the link, substantially as described.
2. In coupling links having flattened or reduced portions to enable them to pass
through a narrow opening or slot into the hole in the draw bar hook, providing
them with ferrules or sleeves or other suitable covering devices so arranged that
they can be slipped on to the flattened or reduced portions aforesaid and hammered
down or otherwise fastened thereto so as to hold them in position, substantially as
and for the purpose described.
3:Thaimprovement in coupling, apparatus for railway vehicles, which consists
in forming the shank on neck of the draw hook, separate from the draw bar, and
with a jaw or open slot through which the coupling link, can be slipped through into
the hole in the hook, the said jaw being so arranged that it will receive the end of

page_text: the draw bar and can be fastened securely thereto, whereby the coupling link can
be locked in place in the hole in the hook and cannot possibly be removed
except by separating the draw hook from the draw bar, substantially as
described.
4. The general arrangement or construction of parts forming my improved
coupling apparatus, substantially as set forth, whereby the customary pin and
shackle is dispensed with, and the coupling link is locked in place in the hole in
the draw bar hook.
