PROVISIONAL SPECIFICATION.
Improvements in Couplings for Railway Carriages and Wagons.
WILLIAM MAUGHAN, Mechanical Engineer, 36, Parliament Street, Middlesbro',
do hereby declare the nature of this invention to be as follows:-
The invention consists of a hook and draw bar with coupling link attached, which
is manipulated by means of a lever and rod attached to the coupling, and moved
from the outside of the carriages trucks or wagons by means of a lever and cross
bar which is kept in position by means of a catch lever and spring on the out-
side of the carriage truck or wagon. In the case of passenger carriages where
the carriages want to be close coupled the said draw bar is manipulated by
means of a spur wheel and pinion working two small bevel wheels which will
either release or tighten the carriages as required.

COMPLETE SPECIFICATION.
Improvements in Couplings for Railway. Carriages and Wagons.
WILLIAM MAUGHAN, Mechanical Engineer, 36, Parliament Street, Middlesbro',
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:―
This invention consists of a hook and draw bar with coupling link attached,
which is manipulated by means of a lever and rod attached to the coupling and
moved from the outside of the carriages, trucks or wagons by means of a lever
and cross bar which is kept in position by means of a catch lever and spring on
the outside of the carriage, truck or wagon.
In the case of passenger carriages which require to be close coupled, the said
draw bar is manipulated by means of a spur wheel and pinion working two
small bevel wheels which will either release or tighten the carriages as required.
The accompanying drawing, which represents in Fig. I a part plan and in Fig. 2
a side elevation of our improved coupling as applied to the front of a carriage,
serves to make the invention clear.
In these figs. A is the hook and draw bar to which is attached the coupling
link B. The link B is raised or lowered by means of the shackle C and links D
attached by the lever D¹ to a weigh bar E. The weigh bar E is manipulated by
means of a handle F on either or both sides of the carriage or wagon. A horned
disc G is fixed on weigh bar E, and works against a catch lever H on side of
carriage. This catch lever is kept in position by a spring K.

page_text: When the carriages are coupled, the horned disc and links are in the position
shown in the figures, with the horn G¹ locked by the lever H. When the
carriages are uncoupled the handle is pulled down and the other horn G works
over the catch of the lever H and forces the spring K back and is locked in the
position to hold the coupling link B out of gear.
The method of drawing the carriages together is accomplished by means of
bevel gearing L as shown on the figures, in which one of the bevel wheels L'
works upon a square thread screw cut in the draw bar A.
The bevel gearing is manipulated by means of the spur gearing M, N and the
handwheel on the sides of the wagon or carriage, and by its action extends
the draw bar A or draws it in as required.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that
what we claim is:-
-
1. An improved coupling device for railway carriages, wagons or trucks, in
which the coupling link attached to the draw bar is manipulated by means of a
lever F fixed on a weigh bar E and adapted by means of the horned disc G and
the catch lever H to be locked in the requisite position for retaining the said
coupling link in or out of gear, all combined and operating substantially as and
for the purpose as herein before described with reference to the accompanying
drawing.
2. In combination with the coupling device as set forth in the preceding claim
of the mechanism designed as a means for extending the draw bar or drawing
the same in, arranged and operating substantially as described with reference
to the accompanying drawing.
