IMPROVEMENTS IN COUPLING APPARATUS FOR RAILWAY TRUCKS OR WAGGONS
Year: 1884

page_text: COMPLETE SPECIFICATION.
I. ISHMAEL DAVIES of the City of Manchester in the County of Lancaster, Coal
Merchant, do hereby declare the nature of my Invention for "IMPROVEMENTS IN
COUPLING APPARATUS FOR RAILWAY TRUCKS OR WAGGONS," and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement :—
The objects of these improvements are to obtain greater safety, and various
facilities in coupling and uncoupling railway trucks or waggons, and consist of a
special attachment to the ordinary chain or other coupling whereby the operation
may be performed without the operator going between the vehicles for that
purpose.
To accomplish this, and to effect my improvements, I attach to the coupling loop,
or the chain link, or other coupling, by means of welding, rivetting, or of mechanical
clips, suitable studs or pins, on which is jointed a double or single bent or elbow
rod or lever or levers, attached to a rod or shaft which passes through a slotted
bearer attached to the body of the vehicle, and which rod or shaft of the bent rod
or lever terminates in a suitably formed handle projecting from the side of the
truck or other vehicle.
The slotted bearer forms a fulcrum whereon the rod or shaft, carrying the lever,
obtains a moveable purchase, in such manner that the operator may couple or
uncouple without passing between the vehicles, by lifting the loop or chain link on
and off the hook at the end of the draw bar or vehicle by means of the bent or
elbow rod or lever or levers before named.
Collars or other stop pieces may be affixed to the shaft or rod carrying or
forming the lever, so as to prevent the same from projecting too far.
But that the improvements may be better understood, I will by the aid of the
accompanying Drawings, proceed more fully to describe means employed by me.
DESCRIPTION OF DRAWINGS.
Fig. 1 shews a side elevation, Fig. 2, an end elevation, and Fig. 3 a plan view
of apparatus arranged according to my improvements.
The same letters indicate corresponding parts wherever they occur.
a. a are the slotted bearers, b. b the rod or shaft carrying the levers c. c.
b. 6₁ are the handles of the rod or shaft on each side of the waggon or truck.

page_text: The levers are connected by means of the pin joints d. d, to the chain or other
coupling in use.
In the Drawing, mechanical clips are shewn for this purpose, and are used by
preference, but the studs or pins may be welded or attached thereto by any other
suitable means, and in some cases single legged levers might suffice for the purpose,
although by preference double legged ones are adopted.
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 :-
The use of a rod and lever or levers attached to, and in communication with the
ordinary coupling apparatus, whereby the same may be actuated from the side of
the vehicle in manner substantially as shewn and described.
