Improvements in Automatic Couplers for Railway and like Vehicles.
MARWOOD JOHN OLIVER, Warleigh View, Bere Ferrers, Bere Alston, R.S.O.,
Devonshire, Merchant, do hereby declare the nature of this invention to be as
follows:-
I hinge a
"combination" link to the ordinary
extending (when in position for coupling) above the draw-bar, high enough, to
be of sufficient length, when lowered to drop in hook of corresponding draw-bar,
"drawbar" the said link
on opposite truck, or carriage, and extending at same time, a sufficient length
below the draw-bar, to have arms attached, on each side, reaching to to inside
of buffer plates. On the approach of carriage or truck to be coupled the buffers
of approaching truck coming in contact with those of truck to be coupled, drives
them inward in the ordinary way, pressing on arms of link when, the latter is
upset, or thrown forward, into its desired place, i.e. inside, hook of opposite
truck, or carriage, thus automatically coupling it. The said link is made in
two or more parts, or hinged, allowing it to yield, or bend on end pressure.
To release, or uncouple, attendant stands by side of truck, or carriage, takes
end of arm (or a sliding lever placed by side of truck or carriage, placed there
for that purpose) lowers, or depresses it, which raises link from hook of other
arriage, at once releasing it, obviating the necessity of attendant, getting
etween the truck, as heretofore, to couple, or uncouple.
When not in use, the link hangs, loosely under the draw-bar, in the ordinary
ay, or stands upright, or leans against end of carriage, or truck, ready for use.
One, two, or more of the appliances, can be placed, and used at both ends of
ch truck, or carriage.

I, MARWOOD JOHN OLIVER, of Warleigh View, Bere Ferrers, in the County
of Devonshire, Merchant, 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:-
In this invention I hinge a combination link to the ordinary draw-bar of a
railway carriage or truck. The said link extends when in position for coupling,.
above the draw-bar, so as to be long enough, when lowered, to drop into 41°
[Price 8d.]

hook of the corresponding draw-bar of the opposite carriage or truck. The
inner ends of the said link are provided with arms bent at right angles, which
arms come behind the buffer plates of the carriage or truck to which the link is
attached.
I make the link in two pieces jointed together.
In order that my said invention may be better understood I will now proceed
to describe the same with reference to the drawings accompanying this specifi-
cation in which Fig. 1 shews a large scale view of link and draw-bar, Fig. 2
shews elevation of the ends of two trucks, with link attachment, Fig. 3 plan of
buffers on end of truck shewing position of link before coupling.
The same letters of reference denote the same parts in all the views.
The link is pivotted to the draw bar a at b as shewn at Fig. 1 and is provided
with two arms c which reach to behind the buffer plates d as shewn clearly at
Fig. 3. The link is made with a knuckle or joint at e so that the end of the
link may swing back in one direction from the straight line (as seen in Fig. 2)
but not forward in the other.
It will be seen on referring to Fig. 2 that the link f¹ on the draw-bar a¹
hangs down as this is not required for use. The other link f is in a raised
position and the arms c come behind the buffer plates b so that when the said
buffer plates are forced inwards by the concussion of the meeting trucks, the
said link will be swung over on to the hook of the draw-bar al with which it
will engage.
To release the said carriages or trucks, it is simply necessary to depress one of
the arms c which raises the link from the hook of the other truck, this may be
done by means of a rod thus obviating the necessity of a man having to go
between the trucks for uncoupling.
When not in use the link hangs loosely in the ordinary way or rests against
the end of the truck ready for coupling.
If found desirable, two or more of these coupling links may be attached to
each end of a carriage or truck.
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. Automatic couplers for railway and like vehicles constructed substantially
as set forth.
2. Couplers for railway and like vehicles, provided with arms extending from
such links so as to come behind the buffer plates for the purpose set forth.
3. In couplers such as those described for railway and like vehicles making
the coupling link jointed substantially as set forth.
