Uur-ran rares `PATENTE' I-I. OLLEY, OF SYRACUSE, NEW YORK, ASSIGNOR TO CROUSE-IINDS COM- PANY, OF SYRACUSE, NEW YORK, A'CORPORATION OF NEW' YORK LAMP RECEPTACLE Application filed October 13, 1927. Serial No. 225,910.

This invention relates to lamp sockets and has for its object a lamp socket in which the outerl sleeve terminal andthe central lamp Contact and wire terminals are a self contained unit and mountable as a unit on a lamp base, which lamp socket is particularly siniple and economical in construction and highly etlicient in use.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed. Y

In describing this invention, reference is had to the accompanying drawing in which like characters designate corresponding` parts in all the views. n

Figures 1 and 2 are respectively, opposite side elevations of this lamp socket assembled on its base.

Figure 3 is a plan view of parts seen in Figures 1 and 2.

Figure 4 is a side elevation of the detached self contained lamp socket unit.

vFigure 5 is a sectional view on line 5 5, Figure 4.

Figure 6 is an elevation partly broken away of the lamp base. v

This lamp socket comprises generally an outer sleeve terminal and a central lamp contact supported entirely by and within the sleeve terminal whereby the sleeve-terminal and the central lamp contact with their wire terminals are assembled as a unit and mountable as a unit on a base, the sleeve terminal having means lfor securing the unit to the base.

1 designates the sleeve terminal which is formed with internal threads 2, the sleeve terminal being open at both ends and having an opening 3 in its side for the wire terminal of the central lamp contact to be presently described.

4 designates the central lamp contact which is carried by an insulating support secured within the inner end of the sleeve terminal 1 and which has a wire terminal 5 extending through the opening 3 to the outside of the sleeve terminal 1 where it is provided with a binding screw 6.

The support for the central contact includes an insulating block as a disk 7 permanently secured in the sleeve terminal 1.

.It is here shown as secured therein by a second insulating disk 8, the two disks thrust-- ing against internal oppositely facing shoulders 9 and 10 within the sleeve terminal, and the two disks being clamped against the 'shoulders by a pin 11 extendinT axially .rivet overlics the wire terminal 5. The cencontact is here shown as in the forni of a "-J' shaped clip having'a hole 14 at or near its angle through which the wire terminal 5 extends to overlie one arm of the clip.

The sleeve terminal is usually formed heavier than the usual screw threaded shell and is provided with a binding screw or wire terminal 15 on the outside thereof, this binding screw 15 being located diaineti'ically opposite the binding screw 6.

The outer sleeve terminal 1 and the central lamp contact with its support thus constitute a self contained unit and this unit is mountable on an insulating base 16 provided with upright segmental arc shaped walls 17 for centering the lamp socket with the wire terminals in line with wire holes 18. The base is also provided with suitable fastening means as screws 2O for attaching it to a fixture.

In order that the rigid screw threaded sleeve terminal will firmly hold the threaded lamp plug or base, it is provided with distorted threads and the threads are distorted by forming a transverse slot 19 in the sleeve terminal, which slot opens through the internal threaded face of the terminal and the slot contracted or the walls pressed toward each other to close or partly close the slot.

The means for securing the lamp socket to the base are here shown as laterally eX- tending lugs 21 provided on the sleeve terminal 1 and overlying the upper ends of the walls 16 or embedded in recesses therein and a screw 22 extending through the base and i threading into the lugs.

'This lamp socket or receptacle is partieuf larly adapted' for situations Where sturdy 5 lamp sockets are desired as trains, cabs of locomotivesvand any other Lvsituation Where f the receptacles are required -to perform heavy duty. Y s

What I claim is: Y 1^. A.v lamp socket fcomprisingan outer sleeve terminal having internal shouldersY lfacing in opposite directions, insulatingdisks Within the sleeve terminal and 'abutting against'said shoulders, means for secur-v l V ing the disks together and holding them against the shoulders and a central lamp conf tact carried by the innermost disk. l2., A- lamp socket Comprising an outer Y 'sleeve terminal having internal lshoulders 2o facing inopposite directions, insulating disks t Y within rthe sleeve terminal and abutting against said shoulders, means for holding --the disks against the shoulders and a central lamp Contaet'earried bythe innermost Y diskthe sleeve terminal having a` wire yterminalearried thereby on the bottom portion Y thereof between saidv shoulders, and the Y central lamp Contact having a wire terminal projecting .laterally therefrom through the sleeve terminal.

. In testimony whereof, I have hereunto signed my name, at Syracuse, in the county of Onondaga, and in the State of New York1 this 10th day of October, 1927, Y

RAYMOND H. OLLEY.
