Improvements in Electric Gas Lighting Appliances and Devices.
,
I, AARON MOSES SLOSS, of 1007 Chicago Opera House Block, Chicago, Illinois,
United States of America, Gentleman, 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 :-
My invention relates to electric gas lighting appliances and devices, and has for
its object in general to provide convenient means for lighting gas jets by means of
electricity, and particularly to provide a light and simple device associated with a
gas fixture.
It is illustrated in the accompanying drawing wherein,-
Fig. 1 is a side view, with parts broken away, of a gas fixture with my gas lighting
device applied thereto.
Fig. 2 is an enlarged view of the lower end of the battery case or holder.
Fig. 3 is a cross section through a modification.
Fig. 4 is a side elevation of such modification with the two parts of the case
opened on their hinge.
Like parts are indicated by the same letter in above figures.
A is the stem or rod of a chandelier or other such fixture; B B the lateral
projecting arms thereon. C is a downwardly projecting cylindrical portion which
serves as a cup or case to hold the battery. C₁is the lower removable portion or
bottom of such cup or case, preferably secured by a bayonet joint as shown. E is
a battery placed in the case C and resting on the bottom C', and having two
elements in the usual manner, but I do not show these in detail. n is a conductor
leading from one element of the battery to an insulated piece projecting within the
cup or case. From this piece leads the two conductors indicated by the dotted
lines, one out through or along or in connection with each arm B B. Each of these
conductors is insulated from the metallic portions of the chandelier and terminates
at the tip 6 in close proximity to the gas jet. The other element in the battery E is
connected by the short conductor shown with one end of the spark coil S, whence
leads the conductor p to the metallic portions of the chandelier.
Mounted upon
each arm pivotally is an elbow crank lever associated with a spring which forces it
normally into the position indicated in full lines. is a pendant pull connected
with one end of the elbow crank lever, and is a contact tip on the other end
adapted to engage the insulated tip b. The contact tip q is connected with. the
metallic portion of the chandelier. These parts are substantially the same in the
modifications shown in Figures 3 and 4, but in this case the cup or case is made of
two portions hinged together and adapted to clasp and thus be firmly held upon the
chandelier stem or rod. The connections will still be substantially the same. My
device could be considerably altered and rearranged as to relation and proportion
and construction of the parts without departing from the spirit of my invention, and
I do not wish to be limited to precisely what is here shown.
It is evident that whenever the two tips b, and q, are brought in contact that the
circuit is completed through the battery and the spark coil, and thus a brilliant
spark is emitted in close proximity to the gas jet. At the same time the battery
and coil are of such size and so related that they occupy very little space and may
be attached as an ornament to the fixture. They may be associated with any
fixture. The device may be attached to old or new fixtures, and any kind of a
fixture.

page_text: Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The combination with a gas-fixture or lamp, of a battery, a spark-coil, and a
case containing said battery and spark-coil, which encloses the junction of the main
supply-pipe with the branches supplying the several burners, substantially as set
forth.
2. The combination with a gas-fixture or lamp, of a battery, a spark-coil, a case
containing said battery and spark-coil and supported by said fixture or lamp, which
case is formed in two parts, one separable from the other, and insulated contact
springs forming the terminals of wires leading to the burners or groups of burners,
which are automatically brought into connection with the terminals of the battery
and spark-coil by the closing of the case, substantially as set forth.
3. The combination with a gas-fixture or lamp, of a battery, a spark-coil, and a
detachable case containing said battery and spark-coil, formed in two parts and
surrounding the main supply pipe of said fixture or lamp, substantially as set
forth.
4. An electric gas-lighting appliance or device constructed and operating substan-
tially as shown and described.
