ELECTRIC IIA nrLAsH NIGHT V Original application filed A ril 11,1928, serial No. 269,188: Divided. and this'application filed 4, 1930. Serial 110,425,856 7 This invention relates to improvements in electric hand flashlights of the type shown, described and claimed in my prior Letters Patent of the United States of America,

dated January 4, 1927, and Numbered 1,613,203, in which a plurality of electric light bulbs are employed with switch means for closing the'circuitsto' any .one of the bulbs or all of them simultaneously. The

present applicationis a division of my copending application, Serial No. 269,188, filed April 11, 1928.

The present Invention relates to the struction of the reflector end of the lamp 1n which a ring of insulation is inserted between the metallic head part of the lamp and the metallic reflector and means for removably retaining the same in place. The purpose of this ring of insulation is for insulating the metallic reflector from the metallic casing of the hand flashlight. Also, it is designed for centering the reflector when it .is inserted in order that the contact terminals of each of the bulbs may engagel'the proper terminal I or battery circuit wires when assembled. A

spring ring is employed for retaining the to be readily removed when the ring ofeinv with the recesses 20, 21 and22 for receiving.

ring of insulation in place but permitting it sulation is to be removed.

Referring to the drawings: Fig. 1 is an elevational view,partially in section, of the reflector end of the lamp with the lamp terminals and thering of insulation retained in place by the spring wire ring. 7

Fig.2 is a transverse sectional view on the line 22 of Fig. 1 showing the ring of insulation with the centrally disposed strip of metal extending across the ring and formed with an opening for receiving one of the terminals of the lamp. 7 Fig.3 is a detail viewof the ring of in sulation removed vfrom the lamp.

Fig. 4 is a sectional view on the line 44 of Fig. 3,showing the centrally disposed opening in the ring and the strip of metal attached to the ring.

Fig. 5 is a detail view of the wire spring for retaining the ring of insulation in place in the head portion of the lamp.

Referring to the drawings in detail:

'in which the three electric bulbs 9, l0 and 11' 5 of the mem February ;1 designatesthe tubular cylindrical member of the'lainp in which the battery, indiengaged by the contact 'strip'3. 4 is the enlarged head portion of the lamp which is formed with threads 5 for receiving the bezel or ring 6 that retains the lens' 7 in place. The metallic parabolic reflector is indicated at 8 are mounted by means ofthe threaded sock ets 12. 13 designates a flat-ring ot insulating material which is located withinthe metallic head member 4: as shown-in Fig. 1. 14; desi'gf nates ahead in which is located thewire spring '15. forretaining'the flat ring of in-. sulation 18 in place, yet permitting it to be readily removed, when desired. This ring of insulation serves to insulate the metallic reflector-.8 from'the metallic casing part 4. 16 is a strip of metal which is attached to the ring of insulation 13 by means. of the rivets 17. This strip is formed with an-open-' ing 18 for receivingthe threaded'socket 12 of the-lamp 10. The ring of insulation is formed with a centrally'located opening 19. through which inner end of the reflector passes as shown; This opening is formed terminal of the lamp 11, while the strip 26 engages the terminal of the lamp 10. Thesecontact strips "are arranged as in myabove j referred to patent, and application. When the reflector 8 is inserted the terminalof the bulb 10 is passed through the opening 18 and engages the strip 26. This opening serves ,7 to readily center the reflectorewhen it is inserted and the recess openings '21 and 22 of the ring 13 -further serves to properly poerence is made to theabove referred to atent. 1

When the ringfiG is threaded onto the t reads ,er 4 the contact strips 23, 24a

and 25 are forced into the recesses 20, 21 and 22 and into contact with the ring of insulation 13. The reflector is therefore firmly held in place when in use. 7

From this description it will be seen that I have provided a simple and inexpensive construction for insulating the reflector from the metallic casing and for positioning the reflector in the lamps when inserted.

'What I claim is:

1. As an article of manufacture for the purpose described, a flat ring of insulating material formed with a central opening and with oppositely disposed recesses extending from the opening, a bar secured to the ring and formed with an opening which is located in the line which passes through the oppositely located recesses, whereby a reflector with a c'entrally disposed socket may be accurately positioned in relation to the ring.

2. In combination in an electric lamp having a metallic cap piece, a metallic reflector located in the cap piece with electric bulb sockets attached thereto, a ring of insulating material engaging the cap piece, a bar diametrically secured to the ring and extending across the opening of the; same, and formed with an axial opening for receiving a bulb socket on the reflector for positioning the reflector in the metallic cap piece, as described.

In witness whereof, I hereunto set my hand this 28th day of January, 1930. V p I JAMES L. SHANNON.
