page_text: I, WILLIAM BENNETT RICKMAN, of 32 Clerkenwell Road in the County, of
Middlesex, Engineer, do hereby declare the nature of this invention to be as
follows:-
A railway carriage that is lighted by gas stored in a reservoir, on the carriage
itself is usually provided at the one or the other end of the carriage with a
regulating cock in the external ascending pipe that leads from the reservoir to
the burners in the roof of the carriage. The plug of such a cock is usually made
to take any one of three positions; in one extreme position it allows full supply of
reduced
gas to pass to the burners, in a middle position it allows passage of a-
supply, and in the other extreme it entirely cuts off supply. My invention relates
to an appliance whereby such a cock (which is usually situated about midway in
the end of the carriage) can be moved from either side of the carriage to any one
of its three positions and held firmly there notwithstanding the shake to which
the parts are subjected by the movements of the carriage. For this purpose I fix
on the plug of the cock a lever made with a radial slot in which a pin can move to
and fro. This pin projects from a sleeve that is held between collars of a round
rod so that the sleeve must travel with the rod longitudinally but the rod can
turn round within the sleeve. This rod extends across the end of the carriage and
has at each end of it a handle that can be conveniently taken hold of by a guard
or other official. At each side of the end of the carriage, just under the handle at
that side, is fixed a projecting plate having three deep notches, each of which is

desired to alter the cock, the attendant at either side of the carriage moves the
one handle next him out of the notch in which it is engaged thus turning the rod
and so disengaging the farther handle. He then pulls or pushes the rod lengthwise,
thus moving the sleeve and its pin which being engaged in the slot of. the cock
lever moves the plug of the cock. He then turns the handle down into another of
the three notches, and both handles being thus, simultaneously engaged in notches,
the rod is prevented from moving lengthwise, and the cock remains as it has
been set.

I, WILLIAM BENNETT RICKMAN of 32 Clerkenwell Road in the County of
Middlesex, Engineer, 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 :-
On
A railway carriage that is lighted by gas stored in a reservoir on the carriage
itself is usually provided at the one or other end of the carriage with a regulating
cock in the external ascending pipe that leads from the reservoirs to the burners
in the roof of the carriage. The plug of such a cock. is usually made to take any
one of three positions; in one extreme position it allows full supply of gas to pass
to the burners; in a middle position it allows passage of a reduced supply, and in
the other extreme it entirely cuts off supply. My invention relates to an appliance
whereby such a cock (which is usually situated about midway in the end of the
carriage) can be moved from either side of the carriage to any one of its three
positions and held firmly there notwithstanding the shake to which the parts are
subjected by the movements of the carriages, as I will explain referring to the
accompanying drawings, Fig. 1 being a part elevation and Fig. 2 a part plan of an
appliance at the end of a carriage, and Fig. 3 being a vertical section on xx.
the plug of the cock A I fix a lever B made with a radial slot in which a pin C
can move to and fro. This pin projects from a sleeve D that is held between
collars of a round rod E so that the sleeve must travel with the rod longitudinally,
whilst the rod can turn round within the sleeve. The rod E extends across the
end of the carriage and has at each end of it a handle F that can be conveniently
taken hold of by a guard or other official. At each side of the end of the carriage,
just under the handle at that side, is fixed a projecting plate G having three deep
notches, each of which is capable of receiving the handle when it is turned down
into it. When it is desired to alter the cock, the attendant at either side of the
carriage moves the one handle F next him out of the notch in which it is engaged
thus turning the rod E and so disengaging the farther handle F. He then pulls or
pushes the rod E lengthwise, thus moving the sleeve D and its pin C which being
engaged in the slot of the cock lever B moves the plug of the cock A.
turns the handle F down into another of the three notches in G and both handles F
being thus simultaneously engaged in notches the rod E is prevented from moving
lengthwise, and the cock A remains as it has been set.
He then
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 appliance for regulating gas cocks of railway carriages, constructed and
arranged as herein described and illustrated by the drawings.
