PROVISIONAL SPECIFICATION
A Signalling Apparatus for Use with Lights, Flags, or Sound
Instruments.
I, ALGERNON WILLIAM ABBOTT Master Marmer of 53 Guilford Street
Russell Square London W.C. do hereby declare the nature of this invention to
be as follows.-
'
This invention relates to an apparatus for signalling with lamps, lights, bells,
histles, sirens or other sound instruments, also flags. For this purpose I provide
an apparatus made after the manner of W J. Lancaster's see-saw shutter for
photographic cameras-Patent No 18,167 of 14th November 1889; and is
worked by a pneumatic ball & tubing with or without a stopcock in the tubing.
On whatever it is applied the action of the lever & piston supplies the
necessary movement. As my apparatus is capable of some modifications without
departing from the principle thereof, I do not restrict myself to dimensions,
materials, or to the precise form or placement of the several parts thereof.
Dated thus 10th day of November 1894.

A. Signalling Apparatus for Use with Lights, Flags, or Sound
Instruments.
I, ALGERNON WILLIAM ABBOTT, of No. 53 Guilford Street, Russell Square,
London, W.C, Master Mainer, 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 relates to the application of pneumatic power for the working of
mechanism on apparatus for signalling, the said mechanism being actuated by the
movement of a piston, or pistons, applied to a lever, or levers.
For the purpose of signalling with lamps, I use a mechanism made after the
manner of W. J. Lancaster's sea-saw shutter," Pat. No. 18,167, of 1889; this
mechanism is affixed either in front, or at the back of the lense; when in front, it
Is either screwed on a thread, or fitted with a 1m which fits tightly on another
rim attached to the lamp, when the mechanisin is behind the lense, the lamp is
fitted with a box-shaped space behind the lense, with a slotted way, into which
the mechanism 18 placed. The mechanism. after being affixed to the lamp, is
actuated by pressure applied by an india-rubber ball, pueumatic pump, or bellows,
attached by tubing to the said mechanism, and in the tubing there is a three-way
cock, this three-way cock is fitted so that an may be let into the tubing to support
the piston when the pressure is released from the pump, ball, or bellows, when it is
necessary to keep the shutter open
In its application to flags, or sound instruments, only a piston and lever-arm is
used, either acting directly, or by meaus of other levers. In its use with Hags, the
lever arm is fitted, at its extremity, with a socket into which the staff of the flag 18

page_text: fixed. In its use with thells, the piston, or lever arm 18 connected to the striker of
the bell. In its use with steam whistles, or sirens, the piston is connected with the
valve of the whistle, or siren.
In the accompanying drawings, in which like figures represent corresponding
parts,
Fig. 1 represents the side elevation of a lamp, showing the mechanism fitted to
the front, (1) being the body of the lamp, (f) the cone carrying the lenso to which
the mechanism () is fitted on the socket (6), (1) being the tubing to which is
attached the rubber ball (6').
Fig 2, is the front elevation of the same.
Fig. 3, is the front elevation showing the mechanism behind the lense; (f) being
a casing which carries (1), the lense; (s), being the mechanism fitted in a slot on
the back (s/1), (s/2), being the stops to keep it from falling through;
Although the drawings only show the mechanisin fitted vertically, yet it is
obvious that it may be fitted horizontally.
Having now fully described, and ascertained the nature of my invention, and
in what manner the same is to be performed, I declare that what I claim is :-
The application of pneumatic power by means of mechanism fitted to signalling
apparatus substantially, as described, & illustrated, in the accompanying drawings.
Dated this Twenty-fifth day of September 1895.
