ELECTRIC LIGHTING ASSEMBLY.

ALBERT H. MARANDA, 0F PITTSBURGH, PENNSYLVANIA.
, ELECTRIC LIGHTING-ASSEMBLY.
Specification of Letters Patent.
Patented July 22, 1919.
Application filed August 10, 1918. Serial No. 249,341.-
To all whom it may concern:
Be it known that I, ALBERT H. MARANDA, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and 'State of Pennsylvania, have invented certhen point out the novel features thereof in claims.
In the accompanying drawing, Figure 1 is a view showing in cross section one form of electric lighting assembly embodying my invention, and Fig. 2 is a view showing in rear elevation the assembly shown in Fig. 1.
Similar reference characters refer to similar parts in each of the views.
Referring to the drawing in detail, the assembly comprises a battery B and an incandescent lamp L. The lamp L is of the usual type having a base 9 which is threaded to screw into a suitable socket, the shell of this base constituting one terminal of the lamp filament and the other terminal being in the form of a knob 10 located at the center of the outer end of the base.
The battery B is of the dry or semidry type, comprising a zinc element 2, a-
At the middle of the front surface of the battery the zinc element 2 is pressed inwardly to form a recess 2 of general semispherical contour, and at vthe base of the recess this element is further pressed inwardly to form a cylindrical hole 2*, which is threaded to form a socket into which the base 9 of the incandescent lamp L may be screwed. The inner end of the socket 2 fits snugly into a suitable hole in the disk 4, as shown in Fig. 1. i
It Will be seen from the foregoing that when the lamp L is screwed into the socket 2 one terminal of the lamp filament is in contact with the zinc element 2 of the battery. Itremains, therefore, to provide means for connecting the knob 10 on the lamp base with the carbon knob 3 to form a complete structure, and this means, as here shown, is as follows. The rim of the zinc element 2 at the innner end of socket 2 is bent inwardly to grasp a button 6 of insulating material, and this button is provided with a rivet-like member 7 of conductive material, the inner head of which is in such position as to make contact with the knob 10 in lamp base 9 when the lamp is screwed into the socket. Clamped between the outer head of member 7 and thesurface of the button 6 is a spring contact finger 8, the
outer end of which is arranged to make contact with the carbon knob 3 This contact finger is capable of rotating on the button 6, so that it may be swung into and out of engagement with knob 3 The finger is preferably bent back on itself somewhat as shown to facilitate manipulation of the finger and to form a hook by which the battery may be attached to belt or any part of clothing,;or hung on a nail or any article that the hook will grasp.
It will now be seen that when contact finger 8 is in engagement with carbon knob 3 the circuit for the lamp will be completed so that the lamp will be illuminated.
The supply of current to the lamp can, of course, be controlled by moving contact ggfir 8 into and out of engagement with The semi-spherical recess 2" in the zinc element constltutes a reflector for lamp L, and to produce the best results it is obvious that this portion at least of the surface of the zinc element should be polished.
It will now -.be evident that I have provided an electric lighting assembly in which the lamp is attached directly to the battery, thus avoiding the necessity for a separate casing or box. Obviously, if the lamp L burns out before the expiration of the life of the battery, or if the lamp is destroyed by accident, it may be replaced by a new one.
Although I have herein shown and described only one form of electric lighting assembly embodying my invention, it is understood that various changes and modifications may be made therein within the scope of the appended claims without departing from the spirit and scope of my invention.
Having thus described myinvention, what I claim is:
1. An electric lighting assembly comprising a battery a portion at least of one element being on the outer surface of the battery and said one element being formed with a socket to receive the base of a lamp, a lamp having a base adapted to fit in said socket and the part of thebase which contacts with said socket constituting one of the terminals of the lamp, and means for connecting the other terminal of said lamp with, and disconnecting it from, the remain ing element of said battery.
2. An electric lighting assembly comprising a lamp having a base, the shell of said base constituting one terminal of the lamp and the base having a knob constituting the other lamp terminal, a battery having a portion at least of one element on the outer surface of the battery and said one element being formed with a socket to receive the said shell of the lamp base, and means for connecting the remaining element of the bat- I tery with the said knob on the lamp base.
3. An electric lighting assembly compris-,
ing a battery having a portion at least of one element on the outer surface, means associated with said one element for attaching an electric lamp thereto, the portion of said lamp which engages said means constituting one terminal of the lamp, and'means comprislng a manually operable contact finger for connecting the remaining lamp terminal with, and disconnecting it from, the other element of the battery.
4:. An electric lighting assembly comprising a battery having a zinc element and a carbon element, said zinc element constituting a portion of the inclosing casing of the battery, the surface of said zinc element having a depressed portion constituting a reflector and the base of said depressed portion being formed to constitutea socket adapted to receive an electric lamp, a lamp having a base adapted to fit in said socket and the portion of said base which contacts with the socket constituting one terminal of the lamp, and means for connecting the remaining terminal of the lamp with the carbon element of the battery.
5. An electric lighting assembly comprising a battery one of the elements of which constitutes a portion at least of the inclosing casing of the battery and said element being provided with a socket to receive the base of a lamp, a knob connected with the other element of the battery and lying on the outer surface thereof, a contact finger movable into and out of engagement with said knob, a lamp having a base adapted to fit in said socket and the portion of said base which contacts with the socket constituting one terminal of the lamp, and means for connecting said contact finger with the other terminal of said lamp.
6. An electric lighting assembly comprising a battery one of the elements of which constitutes a portion at least of the inclosing casing of the battery and said element being provided with a socket to receive the base of a lamp, a knob connectedwith the other element of the battery and lying on the outer surface thereof, a lamp having a base adapted to fit in said socket and the portion of said base which contacts with the socket constituting one terminal of the lamp, said base having a knob constituting the other terminal of the lamp, a contact finger pivotally'mounted on the battery to move into and out of engagement with the first-mentioned'knob, and means for connecting said finger electrically with said knob on the lamp base when the lamp is in place in said ALBERT H. MARANDA.
