Description

Patented July 29, 1930 7 unites STATES PATENT OFFICE manual-ma ni- EDWARD C. ALBRIGI I'I, -OF CONNER-SVILL E, INDIANA, ASSIGNOR TO INDIANA LAMP CORPORATION, OF CONNE-RSVILLE, INDIANA, A CORPORATION LAMP CONSTRUCTION Application filed February 23, 1928. Serial No. 256,139.
This invention relates to a lamp structure, and particularly to a signal lamp embodying a stop signal with a tail light.
The principal object of the invention is to provide a simple and economical construction of contact members connecting the plug of the circuit with the respective lamp bulbs.
The full nature of the'invention will be more clearly understood from the accompanying drawings and the following description and claim.
Fig. 1 is a side elevation of a signal lamp with a. portion thereof shown in central vertical crosssection. Fig. 2 is a section taken on the line 22 of Fig. 1 V
In the drawings there is shown a signal lamp having a casing 10 with a lens'door 11 provided with a stop signal lens 12 and a tail.
light lens 13. Mounted within the casing there is a transverse partition 14 dividing the lamp into the signal compartment 15 and tail light compartment 16Z In each of said compartments there is provided the lamp bulbs 17 and 18, respectively. The rear of thecasing has secured thereon the lamp sockets 19 and 20 extending into the respective compartments 15 and 16 to receive the lamp bulbs 17 and 18 in the usual manner. Suitable projections 21 extendrearwardly from thec-asing for enabling the lamp to be mounted in position on a vehicle. 7 i
The center of the rear Wall of the casing is provided with a flanged socket 22 adapted to receive a bayonet slotted shell 23 in which theusual connecting plug 24 may be removably inserted carrying the circuit wires 25 and 26.
Mounted interior-1y of the casing and held in position by the. shell 23 in the socket22, there is a plug 27 of non-conducting mater al in which the circuit pins 28 and 29 are slid ably mounted in position to be engaged by the contacts of the plug 24 leading from the circuit wires 25 and 26, respectively. The inrigid fiber strip 82, as indicated at 33. Said fiber strip rests upon the inner face of the plug 2'? and'has its opposite ends extending into the sockets 19 and 20. The outwardly extending ends of the contact strips extend into the sockets 20 in position to be engaged by and make contact with the lamp bulbs 17 and 18. The spring contactstrips 30 and 31 have their ends spaced from the fiber strip 32 so that when pressed toward oraway from said fiber strip they will exert a spring tension;
By means of this construction, the inner adjacent ends of the spring contact strips will eXertaQspring resistance to the pressure exerted on the pins 28 and 29'by the engagement therewith of the connecting plug 24. On the other hand, the outer ends of the spring contact strips will exert an outward pressure against the lamp bulbs to hold them in bayonet locked position in their socket and maintain electrical contact therewith.
The invention claimed is:
In a lamp casing, a pair of lamp bulbs spaced apart from each other, sockets mount- 7 ed in said casing for receiving said bulbs, an
insulating plug mounted in said casing intermediate the sockets thereof, a pair of contact pins slidably mounted in said plug, an insulation strip extending from one socket to the other, and a pair of oppositely disposed spring contact strips secured intermediate of their ends to said insulation strip and having their inner ends yieldingly engaging the re spective inner ends of said pins and their outer ends'extending into said lampsockets and yieldingly engagingthe contact points of said bulbs. e
In witness whereof, I have hereunto affixed my signature.
EDWARD C. ALBRIGHT.
