Patnted Apr. 12, 1932 UNITED STATES PATENT OFFICE JOHN T. FAGAN, OF CLEVELAND HEIGHTS, OHIO, ASSIGNOR TO GENERAL ELECTRIC COMPANY, A CORPORATION OF NEW YORK FLASH LIGHT DEVICE Application filed April 28,

- My invention relates to portable flashlight devices comprising a lamp and a holder therefor, usually containing a battery, a socket and a switch. One of the more specific uses of my invention is for photographic flashlights.

Y One object of my invention is to provide a comparatively simple and effective holder for photographic flashlight lamps andthe like. Another object of my invention is to provide adevice into which the lamp may be inserted by a simple thrust movement. Other features and advantages of my invention will appear from the description of a species thereof and from the accompanying drawings.

In the drawings Fig. 1 is a perspective view I of a holder embodying my invention and Fig. 2 is a longitudinal section through said holder.

Referring now to the drawings, the holder comprises the electrically conductive container or shell 10, preferably of metal, containing the battery 11. The said battery rests upon a conical metal'spring 12 in the base of the holder which serves to electrically connect the outer shell of the battery to the shell 10 of the holder and also to push the center contact 13 of the battery against the end contact 14 of the lamp base. The socket in which said base is held consists of a collar formed of a plurality of

segments

15, 16 and 17 (Fig. 1) held in a flared out portion of the shell which are drawn together by a spring 18. These segments are made from an insulating material, preferably fiber, and are peripherally grooved to hold the spring 18. It will be obvious that various types of spring may be, used but I prefer that shown which is simply an endless coil. The means for retaining the socket in the holder comprises a wire spring 19 which expands into a groove in the rim 20 of said holder. The ends 21, 22 of the said spring protrude through a break in the said rim and may be pinched thereon. 'lowsthe removal of said spring and of the 1331. Serial No. 533,474.

together to compress the spring and allow its removal. One end of said spring 22 operates as a switch for the holder as it contacts with the shell of the holder and its end 23, which registers with a hole 24 in the said shell, may be brought in contact with the shell 25 of the lamp base 'by pressure on its loop 26.

Uponlinsertion of the lamp 27 by a simple thrust movement, the base thereof is held yieldingly by the spring pressed

socket segments

15, 16 and 17. Pressure on loop 26 serves to flash the lamp whenever desired. The lamp may be removed by a simple pull Pinching of spring ends 21, 22

alsocket segments

15', 16 and 17. This allows the. removal of the battery 11.

What I claim as new'and desire to secure by Letters Patent of the United States is:

1. In a flashlight device, a holder comprising a conductive shell having a groove in one end thereof, a battery in said holder having an element electrically connected to said shell, a plurality of socket segments supported in the end of said shell below said groove, a spring encircling said segments and a retaining spring engaging said groove and shaped to also engage said segments.

2. In a flashlight device, a holder comprising an open ended conductive shell having a groove in one end thereof and a hole in the side wall-thereof near its open end. a battery in said holder having an element electrically connected to said shell, a plu rality of segments supported in the end of said shell below said groove and constituting a collar for receiving the base of a lamp and locating it opposite said hole, a spring'encircling said segments and a retaining spring engaging said groove and shaped to also engage said segments, the ends of said retain ing spring extending beyond said shell and at least one thereof registering with said hole in said shell and adapted, upon being pressed, to contact with the said lamp base.

3. In a flashlight device, a holder com prisin% an open ended conductive shell havmg a ole in its side wall near its open end; a battery in said holder having an element electrically connected to said shell, a yielding collar supported in the said end of said shell for receiving the base of a lamp and locating it opposite said hole, and a retaining spring engaging said collar, the ends of said retaining spring extending beyond said shell and at least one thereof registerin with said hole in said shell and adapte upon being pressed, to contact with the said lamp base.

In witness whereof I have hereunto set my hand. I

JOHN T. FAGAN.
