do bereby declare the nature of my invention for A COMBINED ELECTRIC BELL
PUSH AND INCANDESCENT LAMP HOLDER AND SWITCH to be as follows:---
This invention relates to a novel combined electric bell push, or contact maker,
and lamp holder and switch, and has for its object the rendering of the same
portable and simple in its construction.
In carrying out my invention I, preferably, use an elongated pear-shaped holder
or handle, made hollow to permit of the passage of the wires to the several
terminals contained therein, and having at its lower, or pendent, end a lens of
suitable configuration and so placed as to permit of a small incandescent electric
lamp being mounted in the handle in proper position having regard to the
lens used.
Near the upper end of the handle, or at any other convenient part of it, a
suitable projection serves, when depressed to complete, by means of suitable
contact pieces, the bell circuit, while the circuit of the lamp is completed as
required by a similar projection and contact making devices or by partly rotating
the lower, or any other convenient part of the handle, contact in the latter case
being made in any well known manner.
The circuits of the bell and lamp are brought within the handle and suitably
connected to the contact making devices either as separate circuits or the two
circuits may be arranged with one common return.

page_text: I CHARLES KRAUSS FALKENSTEIN of 71 and 73 Bentham Road, South Hackney,
London, E. do hereby declare the nature of my invention for A COMBINED ELECTRIC
BELL PUSH AND INCANDESCENT LAMP HOLDER AND SWITCH and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement, reference being had to the accompanying dawings and
to the letters and figures marked thereon; that is to say :-
My invention relates to a novel combination of an electric bell push, or contact
maker, with an incandescent lamp holder together with its switch, the whole being
preferably constructed and formed in such a manner as to resemble the pull of an
ordinary bell rope, and has for its object the rendering of the same portable and
simple in its construction.
In carrying out this my invention I preferably use an outer elongated pear
shaped holder or handle constructed of earthenware, vulcanite, or other suitable
material, and containing an inner cylindrical wooden plug to which the lamp,
together with a small reflector, its circuit wires and contact making device, are
suitably attached.
The outer holder or handle is, for the purpose of facilitating it's production,
preferably made in three main parts or pieces, viz. a central or body piece, a top or
cap piece, the latter formed in two parts, and a bottom or end piece, in which
is mounted a lens of suitable configuration. These several pieces are preferably
joined together by screwing their ends one into the other, and the functions of the
various parts are hereinafter fully explained and illustrated in the accompanying
figures.
The electrical circuits by means of which communication is made with the bell
and the lamp respectively may be either run as two separate circuits or they may
each be brought to one common return as shown diagrammatically on the sheet of
drawings.
Referring now to the accompanying illustrations it will be seen that Fig. 1 is a
vertical section of my invention while Fig. 2 is a diagram showing the method of
running a common return from both the bell and the lamp to the battery.
As shown the outer holder or handle consists of the two part cap piece A. A 1.;
the central or body piece B, and the bottom or end piece C; while the inner
cylindrical wooden plug G is turned so as to accurately fit within the body piece B
into which it is secured in any suitable manner. This plug is bored through the
centre to permit of the passage of the leads or wires to the lamp H, and has
formed on one side of it a suitable cavity or recess to allow of the proper action of
the lamp switch or contact maker as hereinafter explained.
The cap piece A. A 1. is formed with a central opening through which the leads
or wires a, a, a, a, pass respectively to the bell terminals b, b' and to the lamp
terminals c, c¹. The terminal 61 is prolonged in the form of a spiral leaf spring
and terminates at its free end in the contact piece shown between the push E, and

page_text: the terminal b, consequently the depression of the push E completes the bell
circuit, the normal condition of the leaf spring tending to break the circuit.
Similarly one lead of the lamp circuit after entering the cap piece goes to the
terminal c, and thence direct to one terminal of the lamp H, whilst the other lead
proceeds from the terminal c¹ to the contact piece d and thence, when the push F,
is depressed, by the spring e and screw to the other terminal of the lamp H.
The terminals c and c¹ are attached to the wooden plug G as are also the contact
piece d, the spring e, and the reflector g thus the removal of the lamp together with
its connected parts is easily effected.
The lower or end piece C has suitably mounted in it a "Bull's eye," or plano-
convex, lens, and by boring the leads, or wires, a, a, a¹, a¹, of the flexible kind a
beam of light from the lamp, aided by the reflector, can be directed to any desired
position.
Though I make no claim to the arrangement it will be readily understood that
the switching on and off of the lamp current could be effected by partly rotating the
end piece of the holder, in which case the push F would be dispensed with and
the wires and contact pieces suitably arranged to meet the obvious requirements of
the alteration.

When desired to connect both the bell and the lamp to a common return, it is
only necessary, as shown in Fig. 2, to electrically connect together the terminals b
and c and then run a lead or wire from the terminal b to the negative or
the battery the other connections being made as diagrammatically shown.
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
First. The combination of an Electric Bell Push and Incandescent Lamp Holder
and Switch substantially as hereinbefore described and shown in Fig. 1 of the
accompanying drawing.
Second. In a combined Electric Bell Push and Incandescent Lamp Holder and
Switch the modification by which a common return suffices to convey the current
from both the bell and the lamp substantially as herein before described and shown
in Fig. 2 of the accompanying drawing.
