PROVISIONAL SPECIFICATION.
Improved Coupling for Railway Carriages.
I, WILLIAM HENRY PARKES, Army & Navy Club, Pall Mall London S.W.
Inventor do hereby declare the nature of this invention to be as follows:-
My invention relates to coupling railway carriages. The object being to provide
a simple and quick means of securely coupling & uncoupling railway carriages and
trucks together without the necessity of an individual exposing himself to danger.
I provide a Ushaped tilting piece with a projection thereon on one car which falls
when coming in contact with a slotted bar upon the opposite car the outward face
of this projection upon the U shaped piece is provided with an inclined surface, in
order to allow the slotted bar to raise the U shaped piece so as the pin will enter
the slot in the bar. The movement of the U shaped tilting piece is controlled by a
bar working on a square pin attached to the bearing of the U shaped piece and
controlled by a spiral spring, the ends of the bar bearing upon the prongs or
projections in the U shaped piece.
A further modification is caused by using the U shaped piece on one carriage and
a vertical projection upon the other carriage whereby the U shaped piece is caused
to fall down over the aforesaid projection when the carriages come together.

COMPLETE SPECIFICATION.
Improved Coupling for Railway Carriages.
I, WILLIAM HENRY PARKES Army & Navy Club Pall Mall London S. W.
Inventor 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 :-
My invention relates to coupling railway carriages. The object being to provide
a simple and quick means of securely coupling and uncoupling railway carriages
and trucks together without the necessity of an individual exposing himself to
danger. I provide a U shaped tilting piece with a projection thereon on one car
which falls when coming in contact with a slotted bar upon the opposite car the
outward face of this projection upon the U shaped piece is provided with an
inclined surface in order to allow the slotted bar to raise the U shaped piece so as
the pin will enter the slot in the bar.
The movement of the U shaped tilting piece is controlled by a bar working on a
square pin attached to the bearing of the U shaped piece and controlled by a spiral
spring, the ends of the bar bearing upon the prongs or projections on the U shaped
piece.
A further modification is caused by using the U shaped piece on one carriage
and a vertical projection upon the other carriage whereby the U shaped piece is
caused to fall down over the aforesaid projection. when the carriages come
together.
In order that my invention may be fully understood I annex drawings of which
the following is a clear and exact description thereof.
Figure 1. is a plan of coupling connecting two cars.
Figure 2. sectional side elevation.

page_text: Figure 4. Iront view of same.
Figure 5. side elevation of a modified coupler.
Referring to Fig. 1. A are two U shaped pieces hinged at B to the
supports connected respectively to the cars D and E. These U shaped pieces
carry pins F having inclined surface G and loose sleeve F¹.
These pins engage in a slot H in bars I also attached to the cars D and E.
Attached to the said supports C, are two pins J. The controlling bars K are
provided with square holes which engage on the pins J. Spiral springs L are
placed upon the pins J and maintained thereon by the heads M. The rounded
ends of the controlling bar K bear upon the prongs N of the U shaped
piece A.
When uncoupled the U shaped piece is folded back upon the head M of the
pin J, but in the event of the U shaped piece falling down in a horizontal position
the slotted bar I slightly raises it to connecting position owing to the inclined
surface upon the pin F. The mode of coupling is as follows.
F
When the cars D and E come together the inclined end O of the slotted bar I
comes in contact with the prongs of the Ushaped piece A and folds the same
over, the pin engaging with the slot H in the bar I and thus coupling the cars.
When the cars are in motion the controlling bar K allows the U shaped piece to
follow the motion of the slotted bar I caused by vibration of the cars through
inequalities of the road.
Referring to Figure 5. In this case the pin Z carrying a loose sleeve Z' is
carried upon the solid arm Y having inclined surface X which comes in contact
with the inclined surface W upon the U shaped piece V which has an aperture
corresponding to the pin Z. The action is as follows.
When the cars D and E come together the inclined surface X comes in contact
with the inclined surface W, thus folding over the U shaped piece V upon the
pin Z. The coupled position of the cars is shewn by dotted lines T. A ring S is
provided upon the U shaped piece to enable the same to be raised out of connection
with the pins.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is,
1. In car couplers the combined arrangement and construction of parts sub-
stantially as shewn herein and in the annexed drawings.
2. In car couplers the U shaped falling piece having a projection thereon and
carrying a loose sleeve and inclined surface in combination with a slotted bar fixed
upon the opposite car to that of the U shaped falling piece, substantially as
described and for the purpose set forth.
3. In car couplers, a controlling bar and spring for the purpose of controlling the
U shaped piece consisting of a bar working upon a square pin attached to the
bearing of the U shaped piece and controlled by a suitable spring, substantially as
described and for the purpose set forth.
a
4. In car couplers the combination and arrangement of parts, as shewn in
Figure 5 consisting of a U shaped piece fixed upon one car and a pin having
loose sleeve and inclined surface upon the opposite car to be coupled, so that when
the two cars come together the Ushaped piece falls over the pin and couples the
same, substantially as described and for the purpose set forth.
