PROVISIONAL SPECIFICATION.
A Combination of Telephones and Mechanical Signals.
We GEORGE LEE ANDERS & CHARLES HERBERT ELLIOT of No. 10 Bush
Lane, in the City of London, Electric Mechanicians do hereby declare the nature
of this invention to be as follows:-
A magneto telephone combined with the lever pull of an ordinary house bell, or
to a sounding board or other apparatus attached to a strained wire, in order to
facilitate the calling of users of the telephone, without the use of electric currents,
ordinarily used for the purpose.
This invention consists of a small magneto telephone, fitted into a socket
attached to the lever pull or sounding board. One of several ways in which the
saine may be applied is as follows:-The rosette in front of the bell-pull is
removed, & screwed on to the back of telephone; & a new face plate screwed
on to bell pull, in place of the same. This face plate is provided with springs,
to clutch the telephone, when returned into its place, & with terminals for the
connection of line wires.

COMPLETE SPECIFICATION.
A Combination of Telephones and Mechanical Signals.
We, GEORGE LEE ANDERS, and CHARLES HERBERT ELLIOT, both of 10 Bush
Lane, Cannon Street, in the City of London, E.C., Electric Mechanicians 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:-
Our invention relates to a new or improved method of, and means for, combining
magneto telephones with, and upon, any form of agitator, operated at one part of
a house, factory, offices or other building, and connected by a wire, or wires, or
cranks and wires, to a bell, sounding board, or other resonant signal, situated at
some other part of the establishment, and to which is led a strained or tightened
wire connecting a magneto telephone system, where an electric current is not
employed, the object of which is, that the users of said telephone may attract
the attention of each other without the need of an electric or pneumatic instal-
lation, as usually employed for that purpose, and in most cases the ordinary bell
fittings with which houses are usually provided, may be utilized to attain this,
when employed in the manner forming the subject of our invention.
In order that our invention may be clearly understood we have hereunto
appended a sheet of drawings, in which we have chosen to illustrate the applica-
tion of our said invention with and upon the crank pull of an ordinary house
bell.
Fig. 1 is a view of an ordinary bell crank, as employed in most houses for
agitating a distant bell, the ro ette, or cover of which is removed for the better
illustration of our system.
Fig. 2 is a front view of the rosette or cover of Fig. 1.

page_text: Fig. 4 is a front view, and Fig. 5 is a vertical section of, the face plate, or disc,
to be fixed upon Fig. 1 in lieu of Fig. 2.
Fig. 6 is a view of Fig. 1 with Fig. 4 fixed thereon.
Fig. 7 is a perspective view of an ordinary magneto telephone upon the back of
which we fix the rosette or cover Fig. 2.
Fig. 8 is a perspective view of the entire apparatus.
In carrying our invention into effect we remove from an ordinary bell crank A
Fig. 1 the rosette or cover B, Fig. 2, which is usually fastened thereon by means
of an internally threaded recess a on the back of B, engaging with a threaded
axial stud upon the face of A. The magneto telephone Fig. 7 is provided on
its back face with an axial stud similar to b, and upon this we screw the rosette,
or cover B. A circular disc or face plate C, Fig. 4, which may be of vulcanite,
or other suitable material, and preferably furnished with a central internally
threaded bush ć, is screwed upon b, or A, occupying the place previously held
by B, as shown at Fig. 6. Upon the outer periphery of C we fix two ordinary
terminals dd', to which are attached the line wires of the telephone circuit, and
carry the flexible wires e of the magneto telephone D, Fig. 7. Also the
проп
periphery of C, we fix three or more spring clips, or their equivalents, which
grasp and retain D, upon C, when not in use, with the rosette or cover B, outer-
inost, which serves the double purposes of, ornamentation, and the protection of
the telephone diaphram from dust and dirt, as shewn at Fig. 8.
When the operator present, in the room or other apartment in which the
apparatus described is situated, (and whom for the sake of brevity we will call
No. 1) desires to correspond telephonically with the person situated in the other
apartment to which the telephone wires lead (and whom for the same reason may
be referred to as No. 2) he simply agitates the crank handle E in the usual
way, which operates the bell, or other resonant signal situated in, or near the
apartment occupied by No. 2. No. 1 then removes D, from C, and the corre-
spondence may then be carried on in the usual way, and when this terminates
No. 1 replaces D, upon C, with B outward as before."
A similar apparatus may be fitted up near to, and for the use of No. 2, in
order that he may signal the attention of No. 1 in the same manner, and it is
obvious that the same system may be carried out by a suitable arrangement of
signals and line wires, so as to form a like communication between any number
of persons, or apartments.
By this means we are enabled to arrange a magneto telephone circuit, or circuits
accompanied by a mechanical signal, or signals of any form or design, capable of
being operated by a crank, or pull, and when said signal is that of an ordinary
house bell, the method and means herein described of removing the rosette or
cover B, and placing the same upon the back of the telephone D, and this upon C
in the manner shewn, scarcely alters the general appearance of the bell crank in
ordinary use, and provides a neat appearance, combined with a cheap quickly and
easily arranged magneto telephone signalling apparatus, without the need of either
an electric current, or pneumatic appliance.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is.
In a combination of telephones and mechanical signals the method and means
herein set forth of attaching to the crank or equivalent agitator of a bell or other
resonant, or attractive signal a face plate, or disc C, of any suitable material,
screwed or otherwise fixed upon A, and carrying terminals dd', connecting the
telephone circuit, and provided with spring clips, or their equivalents f, for grasping
and holding the magnete telephone D, when not in use, the manner of transferring
the rosette or cover B, from the crank A to the back of the telephone D, the

page_text: whole constructed combined and operating substantially as and for the purposes
herein described and shewn by the accompanying drawings.
