Application filed February 19, 191 Serial No.819,730.

Z10 all whom it may concern Be it known that l, \YILLIAM E. Coarro, a citizen of the United States, and a resident of Toledo. in the county of Lucas and State of Ohio, have invented (1H Improvement in Flnsl lights, of which thefollowing is a speci cation.

My present invention relates to electric flash liqhts, and one of the principal objects thereof is to provide a liush light which may be used with the standard sized dry cells.

Another objectof the invention is to provide a light of the class described which may quickly and easily be attached to or removed from a dry cell, and which may be adjusted when in place thereon in positions where flash or steady light may be obtained.

A further ohject of the invention is to provide a device of the class described, which will be simple. durable, efficient in operation and inexpensive to manufacture;

With these and other objects in View, which will become apparent as the description proceeds, the invention resides in the construction, combination and arrangement of parts will be hereinafter scribed and claimed. and accompanying drawing, in which like characters of reference indicate like parts throughout the figures. of which- Figure 1' represents a perspective view of the invention as applied to a dry cell of standard construction. Fig. 52 represents a vertical sectional view through the same. Fig. 3 represents a horizontal sectional view through the device taken on the plane indicated by the line 3-3 of Fig. 2. Fig. 4- represents a sidc clevuiionul VlQW of the spring means adjusting the contact between the bulb and the positive pole of the buttery.

Referring more particularly to the drawing: indicates :1 drv butter of standard size and mustruciion. whose carbon or positire pole indicutcd iii 6. and whose negative ole 7 consists of the usual bindingpost.

The inrentirni comprises an attachment which may he positioned on the battery. including n cyliiulricul bodv portion 8 open at one e d. and having its opposite end in- .vurdl lunged as at J to provide 11 sent. for u coucnnr-convcx reflector 1.0 which is [)(mh tinned within the bod) member 8, and whose edge is outwardly flanged R at to rest f A double convex lens ll nguinst things 0. l'P lS at its edge upon flange l0. and said lens and reflector are nmlntuiued in position by fully de-' illustrated in "the "means of a collar 12 norided with an inwardly turned flange l3 embracing the edge (if the lens, said collar being thrc-tided onto the end of tube 8 adjacent tlnnge 9. The concavity or curvature of the flanges l0 and 13, conform to the curvature of lens 11 at its edge. so that the lens is snugly seated in place.

The re lcctor 10 is provided at its'ccntral portion with a threaded neck 14- projecting outnnrrllv with respect to the reflector and positioned within neck 14, is shnnk 15 of an electric light bulb 16. The shank projects slichtlv bcyond neck 14, and is provided with the usual contact point 18. A. second contact point is provided, which comprises :1 nictullic stud 19. having an enlarged fiat hoe l. 20, against which n flanged insulating sleeve 21 rests. said sleeve being supported by the shank of the stud. and against the sleeve at the opposite side thereof from head 20, rests an insulating collar 22, and surrounding suid sleeve between collar QQand the flange onthe sleeve, is one end of a coil spring the opposite end of which is udaptod to thread onto the outer surface of the threaded neck i l. ,The function of spring 23. is to maintain points 18 and in constant. Contact.

Positionedon stud 19 between the collar and a nut or head 24, is one end of a second coil spring 25. the opposite end of which is adapted when the device is positioned on the dry cell to contact with the carbon polo 6 of the cell, thus setting up the positive brunch of on electric circuit be tween the lamp and the battery through the positive pole (3. spring 25, stud 19, and contacts 20 and 18.

The inside diameter of'tube 8, is substantially equnl to or slightly larger than the outside diameter of the dr cell, and as cl'cnrly illustrated. the tube adapted to be clipped over the cell so that the spring will contact with the positive pole 6. and in order to maintain the tube in place, the some is provided hear the end opposite the lump with an lllWillkll. 'v' iidircctcd annular bend 26, and is further pro ided with a plurality oi. inwardly stumped lugs 27 :uluptcl to couct with bond 20 in holding the tube fil'llllf, in place on the cell. The wh provided on one side with a spring tub 2S stamped outwardly fromv the tube and adapted to overlie the negative pole 7 of the cell in spaced relation thereto. By
