Improvements in Couplings for Railway Wagons and the like.
I, WILLIAM MOKENZIE, of 53, George Street, Edinburgh, N.B., Goldsmith,
do hereby declare the nature of this invention to be as follows:
A
This invention relates to improvements in couplings for railway wagons and
the like. In the carrying out of my invention I employ the usual draw hooks.
I pass a bolt through the shank of the draw bar hook, upon which is pivoted
a link. The same on the opposing wagon. Each link is of such a length that
it is capable of hooking on to the opposing hook. A pin is passed through the
nose of each hook, the outer ends of which pin act as supports or regulators
for the link so that it cannot fall below an approximately horizontal position.
When the trucks strike each other, the one or other of the links strikes
the ordinary inclined face of the opposing hook and drops into it by its own
weight. In order to disengage the link, I provide a rod which runs along the
bufferbeam, with an operating handle or lever at each side of the truck.
pinion is keyed upon the centre of this rod. Attached to the said pinion is a
flexible rack piece which may be constructed of a series of short links and pins,
the other end of the flexible rack or chain being attached to near the back
end of the pivoted coupling link. By giving a motion of partial rotation to
the pinion, by means of the actuating rod, the link is raised through the
medium of the chain piece. By the employment of the flexible rack for the
purpose of elevating the coupling link, the coupling link may be raised or
lowered by hand independently of the elevating rod, that is to say when the
coupling link is elevated by hand the chain piece doubles up without actuating
the elevating rod, and the said link may be lowered also without operating
the elevating rod.

Improvements in Couplings for Railway Wagons and the like.
I, WILLIAM MCKENZIE, of 53, George Street, Edinburgh, N.B., Goldsmith,
do hereby declare the nature of this invention, and in what inanner the sune
is to be performed, to be particularly described and ascertained in and by the
following statement:-
This invention relates to improvements in couplings for railway wagons and

page_text: In the accompanying drawings, forming part of this specification, Fig. 1 is
a sectional elevation and Fig. 2 a plan of the headstocks of two wagons showing
them coupled.
Referring to the said drawings. I employ a link A pivoted to the draw bar
hook B by means of a bolt (or the like. A pin D, is passed through the nose
of each hook, the outer ends of which pin act as supports or regulators for
the link A so that it cannot fall below an approximately horizontal position.
Each draw bar hook of the wagons is fitted with such a link, the arrangement
being such that when the trucks strike each other, one or the other of the
links strikes the inclined face of the opposing hook up which it ascends,
the link finally dropping into the hook by its own weight.
In order to disengage the link. I provide a rod E which runs along the
buffer beam and is fitted with an operating handle or lever F at each side of
the truck. A pinion or toothed quadrant is keyed upon the centre of this
rod. Attached to the said pinion is a Hexible rack piece or sprocket chain II
constructed of a series of short links and pins ', the other end of the flexible
rack or chain being attached to a crutch near the back end of the pivoted
coupling link A. By giving a motion of partial rotation to the pinion G.
by means of one of the handles or levers of the actuating rod E, the link A
is raised through the medium of the rack or chain H. By the employment of
the flexible rack for the purpose of elevating the link A, the link may be
raised or lowered by hand independently of the elevating rod, that is to say
when the coupling link is elevated by hand the chain piece doubles up.
Similarly the coupling link may be lowered also without operating the elevating
rod.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. The general arrangement, construction and combination of parts consti-
tuting the coupling for railway wagons and the like, substantially as herein-
before described and shewn in the accompanying drawings.
2. The combination of the single link A pivoted to the draw bar hook of
the one wagon, with the similar link A pivoted to the draw har hook of the
opposing wagon, arranged and engaging, substantially in the manner as herein-
before described and shewn in the accompanying drawings.
3. The means for disenaging the liuks A, A, from either side of the wagon,
substantially as hereinbefore described and shewn in the accompanying drawings.
