ELECTRIC LAMP.
Application filed January 6, 1922. Serial No. 527,457.
1 '0 all/whom it may concern:
Be it known that I, iVaL'rEn F. Rnn1 a citizen of the United States, residing at Chicago, in the county of Cook and State.
the night, or during the daylight. This I accomplish by simple and economically constructed means hereinafter fully described, and as claims.
In the drawings:
Figure l is a sectional View of an electric lamp possessing my improvements.
- Figure 2 is an outer end view of the same.
Figure 3 is a cross-section taken on dotted line 3, 3, Figure 1.
Fig. 4 is a section taken on the line 44 of Fig. 1 and Fig. 5 is a detail sectional view.
My invention can be used in connection with an ordinary dash-light or may be distinct therefrom. When used with the dashlight the casing 10 of the dash-light 11, as a rule, has a basal flange that is secured by rivets Or screws to the instrument-board (not shown) and projects rearwardly therefrom. The casing is cylindrical but the an derside of this casing is open under lamp 11 and its end heretofore terminated in a head 12. My improvements, however, require an extension 13 of the casing beyond said head,
and in this extension my improvements are placed.
The outer or rear end of this extension is exteriorly screw-threaded, and it is closed by a. cap, 22, hereinafter more fully, described. The mouth of extension, 13, is stopped up by a plate 14- of insulating material, which is provided with, say, five lamp sockets, 15, that extend from the rear forward, and are, preferably, located an equal distance from the center of the plate 14, and, practically an equal distance apart.
particularly pointed out in the.
Small electric bulbs or lamps 17 are inserted in these sockets, and the contacts 18 onthe ends of the bases of said lamps are adapted to come into engagement with a metal plate 21, that is shaped like a five leafed clover and is securely fitted to the plate 14, opposite head 12. The center of the negative-plate 21 has a central protuberance19 projecting from its forward side (that is, the side opposite plate 14,) and the opposing side of the head 12 has a tubular boss 23 projecting toward contact-plate 21. A metal terminal 24 is placed within the .bore of the boss and it is pushed toward plate 21, by a coil-spring 25, as far as a circumferential flange 23 that projects therefrom and engages the reduced mouth of. the boss 23, will permit. The terminal 24 is connected to the negative wire 25 of.
the circuit in which the bulbs 17 are placed, and when it is desired to close said circuit to the plate, a lateral screw 26, that is tapped through a bushing 27 of insulating material in the casing, is screwed into the casing, and its inner end comes between the protuberance and the terminal and electrically'connects the same.
Each of the bulb bases'engages a positive terminal 28, when fitted into its socket. This terminal consists of a metal head 29 that is placed in a small chamber in. plate 14-, alongside of the socket and is mounted on the end of a longitudinally disposed fiat s giring 30, and thereby kept bearing through the wall of the socket against the base of the bulb. Spring 30 extends through plate 14, in which it is anchored, and terminates in the positive-wire, 31, of the circuit, which latter is insulated and extends through contact-plate 21.
The positive-wires 31 and the negative wire 25 extend forward, within the cylindrical casing toward and out of the flanged lVhen this dash-light is used a metal socket, 33, is employed that is cylindrical and of less diameter than the casing of the lamp in the base of which it is arranged axially. The forward ed- 'e of this socket 33 is welded or otherwise secured to the flanged end of the casing. I I
Screwed onto the screw-threaded end of end of the same, and over the dash'light 11.
the extension 13 is a cap 22, and the outer head 36 of this cap has a cluster of cut crystals or jewels 37, inserted and secured therein. These jewels are arranged with relation to the axial center of the head 36 and in relation to each other the same as bulbs 17, and are in axial alinement therewith.
This improved lamp is particularly adapted for use in connection with my application tor-Letters Patent of the United States for improvements in gauges for gasoline tanks, Serial No. 527,456, filed even date herewith, and the object of the series of bulbs 17 is to glow one after the other, and give the chauffeur or other observer an instant indication of the depth of the gaso line in the tank, (not shown). This he does by noticing whether the glow is in the lower jewels, or in the jewels between said lower jewels.
If desired, a central socket 38 may be made in plates 14- and 21 and a lamp or bulb, 39, similar to bulbs 17, be inserted therein, and be closed to a separate circuit (not shown), and a central jewel may be inserted in head 36 of the cap 22. The light from bulb 39 will glow through this central jewel ll), and in order to distinguish it from the other jewels, I prefer to make it blue and the others red. Any other difierentiation of colors, however, will do.
I do not wish to be confined to the use of five bulbs, or jewels, as any other number from two up would answer.
What I claim as new is:
1. In combination, a tubular casing, an insulating block mounted in said casing having a plurality of passages each passage constituting a socket to receive a lamp base. .a metal plate mounted on the rear face of said block having a finger projecting over the rear face of each of said passages the finger constituting a terminal for the socket, and a plurality of members, one for each socket, passing through the insulating -block and entering said sockets through the walls thereof and constituting the other terminal in each socket.
2. In combinatioma tubular casing having a lateral opening, a 131111) socket within said casing and accessible {through said opening, an insulating block disposed at the forward end of said casing, said block having a plurality of passages adapted to receive lamp bases, socket terminals in said passages, and a cap mounted on the forward end of said casing and a plurality of lenses mounted in said cap and disposed over the said sockets.
In witness whereof I have hereunto set my hand this third day of January, 1922.
