FRANK In FITCH, OF SANTA'CRUZ, CALIFORNIA.

ELECTRIC-LIGHTED rmnnn.

Specification of Letters Patent. Patented June 20, 1911.

Aunlication filed August a, 1910; Serial No. 575,306.

My invention relates to w1re or like findersand especially pertains to electriciappliances or tools of the class named.

The purpose of thls invention 1s to provide a simple, eflicient, practlcal and durable tool, plumbers, gas-fitters, electricians and others,

where it is sometimes necessary to perform work in such places and under such conditions that it is imposslble, ordinarily, to

see the material worked upon, or to easilyand quickly perform the labor.

The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which Figured is a perspective View of the device as used in a partition of a building. Fig. 2 is a detail sectional view of the finder. Fig. 3 is a full-size perspective view of'the tool. Fig. 4: shows a rigid connection with the barrel.

The tool comprises a suitably shaped base or barrel A, of appropriate material, having a removable ferrule or guard 2, screwed on the lower end and partly covering and protecting a small electric bulb 3 screwed into the barrel A,so that its filament ends will make electrical connection, one with the barrel and the other with a terminal 4: of a rod 5 insulated within, and passing through, the barrel. The other end of the barrel is closed With a socket piece or cap 6, to which are secured the Wires Tconnected to a battery One of the wires? is'insulated fromthe cap 6 and terminates at 8, so that'when this is screwed the'rod 5. In this way a circuit is comparticularly useful to .machinists,

pleted through the casingand rod from "the Wires 7 and across the lam 3. By forming on the ferrule an eye or guard yoke 11 arching over the bulb 3, and making it more or less pointed, it will easily guide itself through holes and crevices and protect the lamp from breakage. In order not to cast a shadow in front of the tip of the eye or yoke 11, the latter is perforated at 12, so that the .rays of light from the bulb may project in the line of the axis of the tool; the tool illuminating the space into which it is passed sufiiciently to permit the workman to proceed rapidly and correctly with the operation, and is inexpensive, small and "durable. y

In wiring a building, a. Workman with this tool hasonly tobore a small hole through the stud'cap B, Figf l, and let the barrel down by the board 3 until the light is clearly visible through, the previously made holes C in the wall at which point any electric or gas fixtures are to be applied. The light being easily and quickly perceived, he does not haveto blindly grope with the ordinary hookingtool to pick up the cord or wire Within the partition. Having hooked the small barrel out through a hole C, the wire 7 is disconnected from its'battery above the cap B, and then'the regular wire to be installed is fastened on and pulled through.

Many hours of time required for fishing through partitions and in various other places, as machines, are saved by this tool, which may be provided with a rigid rod or tube 10, so that it may be used in any angu lar position.

Having thus described myinvention, what I claim and desire to secure by Letters Patent 'is- V 1. A finder comprising a barrel, a removable cap at one end thereof, an electric light bulb fitted to the other end of the barrel, and a guard fitted to said last-named end and extending lengthwise therefrom, and

havinganaxially disposed light opening in i barrel, a reinovable cap at one end thereof, an electric light In testimony whereof I have hereunto set bulb fitted to other end of the barrel, and a my hand in the presence of two Subscribing guard fitted to and extending lengthwise witnesses.

from the last named end of the barrel, said FRANK L. FITCH guard being upon one side of the light bulb Witnesses: and having a light opening formed axially CHRISTIAN HOFFMANN 3 through one of its ends. OSCAR A. T'ALLE.
