MARK BAILEY, Hollies Lodge, Clarence Road, Wood Green, London N. Electrician,
and JOHN WARNER, 21 Osborn Street Whitechapel London E. Ironfounder, 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 combined battery and circuit closer; its object being to
dispense with the ordinary detector, pull or push, used for closing electric bell, or other
similar circuits, so saving their cost, and the labour and expense involved in fixing them;
promoting the highest economy in the working of the cell employed, by stopping local
action, and ensuring complete admixture of the excitants used, by constantly rousing,
or keeping the fluid in them in motion; and by the same means preventing
polarization.
We carry our invention into effect in the following manner which will be the better
understood by reference to the accompanying drawing, in which :-
Fig. 1, Shews our invention mounted up as a door alarm.
Fig. 2, Shows an enlarged view of one form of the combination.

for enabling the closing wire, or cord to be led in any direction.

Fig. 7, Enlarged view of bracket and counterbalance.
We provide a box or frame A Fig. 2, of suitable size to contain the cell or cells
employed this box or frame may be made of wood, or it may be cast or formed in
any suitable metal.
Within the box or frame is placed the cell B, which may be of
any type suitable for our purpose, but is preferably fitted with a zinc rod C, as the
negative element.
Upon the box or frame A, we mount a universal bracket or lug e, this may be formed
of wood or metal independent of the box or frame, or it may form part of the casting,
if the box or frame holding the cell or cells is formed in metal. At a suitable point in
the universal bracket or lug e, we form a cruciform slot hole, and through this we
pass a guide pulley F, having a screwed tail formed upon its end opposite the pulley,
to which a nut is fitted.

page_text: This pulley is fastened to the bracket by the nut described in such a position as to
permit a wire, piece of string, metallic tape, or other connection G, to run freely over
it, this wire, string, or tape, is fastened to the zinc or equivalent rod or plate forming
the negative element of the cell at one end, and to the door H, at the other.
Fig: 1, Shews our invention mounted upon a door frame; the door H, being in the
closed position. The wire G, is shewn fastened to the door by means of a simple hook,
and when in the closed position the zinc rod or plate is lifted quite clear of the exciting
fluid contained in the cell B, so breaking the circuit, dispensing with a door trigger,
detector or other equivalent device, and stopping all corroding action upon the zinc
or other rod or plate h. Upon opening the door the zine or equivalent rod or
plate h, is lowered into the cell, the circuit completed, and the bell or other means
employed for giving an alarm is sounded.
In the case shewn in Fig. 1, the connections to the bell, gong, or other means
employed for giving an alarm, are made, to the terminal on porous pot a, and to the
metal box or frame A, the wire supporting the zinc, making good contact with the
pulley, and through it to the lug on frame A.
When a wood box or frame is employed as in Fig. 2, we prefer to solder the ends of
the wire direct to the elements forming the battery.
If desired two or more cells may be mounted up in the way and manner shewn in
Fig. 6. In this case the zinc or equivalent negative elements are connected by
means of an insulating strip x, to the centre of which is fastened the wire, string,
or other equivalent means for raising them as already described, the connections
being made as shewn.
In applying our invention to door pulls or to similar purposes we proceed as
follows; see Fig. 4 & 5. The cell is mounted in a frame or box of wood or metal.
A metallic wire is fastened to the zinc C, at one end, its other end being fastened to a
bell crank lever p, insulated from the frame of the cell upon which it is mounted,
a wire or piece of string is connected to the bell crank as at W, and passes through a
small hole provided in the door post, a lead or other weight O, being fastened to it.
In order to keep the zinc clear of the fluid in the cell the bell crank is provided
with a counter balance spring or other equivalent device, or the existing bell crank
usually mounted on door posts can be utilized for this purpose an ordinary check
spring being employed.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed, we declare that what we claim is
1st. A combined battery and circuit closer consisting of any known elements, the
zine or equivalent element being lifted out of the exciting fluid by the closing door,
window, flap, or other device to which it is attached. Substantially as described.
2nd. The combination with a battery and circuit closer constructed as described, of
the cruciform lug, pulley and adjusting nut fitted with metal wire, said lug acting as
one terminal of the battery employed as setforth.
3rd. The combination with a battery and circuit closer as described, of the insulated
bell crank and counterbalance or check spring. Substantially as described for
Figs. 4 & 5.
4th. The application and use with a combined battery and circuit closer, of the
existing form of ordinary bell crank and check spring, for the purpose of raising and
lowering the zinc or equivalent element into, or out of the exciting fluid as set forth.
