r IIIH UNITE 'rrs ROBERT J. OWENS, or PHILADELPHIA, PENNSYLVANIA EMERGENCY-LIGHT CONNECT'ER Application filed October 15, 1925. Serial No. 62,521.

Many business and professional enterprises are seriously inconvenienced when, for any reason, the electric light supply is cut 11, and it is the object of my invention to devlse novel means whereby, When the electric light supply is, for any reason, interrupted, a source of light supply can be provided by the use of a flash light which can be inserted in the ordinary electric light socket, so that by 1 simply removing the lamp and screwing the flash light into place in the electric light socket the work will not be interrupted.

It sometimes happens when a surgeon is in the midst of a serious operation that the electric. light service is interrupted and no lighting means are present to enable the surgeon to complete the operation, and in some cases this involves serious complications;

With the above and other objects in view,

my invention comprehends a novel construction and arrangement of a flash light adapted to be received in the ordinary electriclight socket of house lighting circuits, so that the flash light can be used in the place of'an elec-- tric lamp of ordinary electric light sockets. It further comprehends a novel construction and arrangement of an emergency cap which is adapted to replace the end cap of a flash light, said emergency cap having ex tending from it a threaded sleeve which can be inserted into an ordinary electric light socket. I v r Other novel features of constructionand advantage will hereinafter more clearly ap pear in the detailed description and the appended claim. a V Y For the purpose ofillustrating the invention, I have shown in the accompanying drawing a typical embodiment of it, which, J in practice, will give reliable and satisfactory results. It is, however, tobe understood that this embodiment is typical only and that the various instrumentalities of which my invention consists can be variously arranged and organized, and the invention is not, therefore,

limited to the precise arrangement and 01-- ganization of these instrumentalitiesas herehr 13x) 7 in set forth.

Figure 1 is a front elevation of an emergency hght and connecter therefor, embodying my invention and in assembled position with a conventional'lamp socket.

Figure 2 is aperspective view of the emergency' light in detached position.

Figure 3 is a sectional view ofythe cap or connecter. o

Figure dis a sectional view of another embodiment of my invention. a Similar numerals of reference indicate corresponding parts. r i

7 Referring to the drawings 1 designates'a flash light of any desired or conventional type having a casing 2, to'one end'of which'is secured the lens 3 by means of athreaded sleeve 4:- The casing contains the usual battery and electrical connections to the conventional lamp. The battery terminal is electrically connected with the casing in the usual manner by means of a spring 5, which is seated in and contacts with the emergency cap 6, embodying my invention.

Thebody portion of the cap 6 isin the form of athreaded sleeve 7 which at its rear end merges :int'o an inwardly extending end flange 8 of the cap. This flange merges into the inner end of a tubular sleeve 9 which is threaded as at'10 and which has an opening 11. p

This opening 11 may, if desired, be closed by a plug of insulating material 12.

F or convenience of manipulation the cap is preferablyzprovided with a raised'knurled portion'13.

The flash light is ventional switch 14, v

15 designatesa conventional electric light socket'from which the lamp has been reprovided with the conmoved and into which the plug end of the flash light has been inserted. V

The operation will now be readily apparent to those skilled in this art and is as follows The flash light operates in the well known manner, the circuit through the lamp being opened and closed by manipulating the switch 14. a r

If the electric light circuit becomes tem-' porarily interrupted, the lamp at the place where the work is being done is removed from its socket, and the threaded plug 9 attached to the flash light is screwed into place in the lamp socket 15. The switch 14 is then actuated to close ..the electric circuit of the flash light, and the workman is able to proceed with his work.

In many cases arising in practice, a multiple socket is used, and the flash light is secured to one of said sockets so that it is always ready for use when needed, and the other socket or sockets would carry the con- 7 ventional electric lamps. T

It will now be apparent that V vised a new and useful mechanically controlled switch plug which embodiesthe features of advantage enumerated as desirable in the statement of the invention and the above description, and that while I have, in the present instance, shown and described a preferred embodiment thereof which will give in practice sat-isfactory and reliable results, it is to be understood that this embodinient is susceptible of modification in various particulars without departing from the spirit or scope of the lnvention or sacrificing j any of its advantages.

Having thus described my invention what I claim as-new and desireto secure-by Letters Patent, is

An emergency cap fora flash light, comprising a cap to replace the customary cas ing cap of the flash light, said cap having athreaded body portion from which extends outwardly a threaded plug adapted to be received in a conventional lamp socket, and

' said lu havilw an o enin throu 'hits outer end to prevent the lamp lighting circuit being closed through the lamp socket and the flash light casing.
