To all whom it may concern:

Be it known that I, LEON M. ToroosLAN, a citizen of the United States of Amerlca, re-

siding at Springfield, county of Hampden, Commonwealth of Massachusetts, have in vented certain new and useful. Improvements in Flash Lights, of which the followe ing is a specifica ion.

This inventionrelates to im electric flash light lamps.

p An object of the invention is to provide an electric lamp which may be used for sev eral purposes, first, as the usual or common flash light; second as a device for testing fuses in order to determine Whether or not the fuse is a perfect one and third; as a device for testing or locating grounds of an electric machine, circuit, motor or dynamo.

A particular object of my improvement is to provide a convenient electric light whereby a workman may conveniently use both of his hands in making overhead repairs or installations of various kinds of apparatus and devices as overhead shafting' constructions, or electric wiring or other fixtures.

The improvement, in general, comprises the usual tubular casing, or, member, in which the battery cell is located, the electric bulb and reflector atone end of the casing and a switch for opening or closing the electric circuit. In addition to these parts there is provided devices for the-objects referred to above. Y Referring to the drawings which form a part of the specification,

Fig. 1 is an external elevational view showing the complete lamp.

V Fig. 2 is a sectional view. on the line 2--2 of Fig. 1 through the axis of the casing showing the interior construction and assemblage of the various parts of the device,

' and in dotted lines the lamp part and its plan view of Fig.

provements in Fig. 9 is-adetail sectional viewof Fig. 8

on the line 9-9 of Fig. 8.

Referring to the drawings in detail:

\ 1 designates the metallic enclosing casing member of the lamp, 2' the usual dry battery cell there1n, the negative terminal of which may be indicated at 3 which rests against a spring 4-that is attached to the internally threaded closing cap 5, whereby the metallic caslng 1s electrically connected to the battery. -6.des 1 ates a cup-shaped insulating member who is located in the opposite end of, the metallic casing 1. This member is attached to the casing by means of the screws 7 and 8 which pass through openings in the block of insulating material 9.

Attached to the block 9 is a rotatable part I 10 by means of the screw 11 which passes through the block 9 and its inner end 11' contacts with the metal plate 12 which is located on and attached to the cup-shaped insulating member 6 by means of the screws 18. '14 is a slidable circuit closer thumb piece which is attached to the contact plate 15 by means of the two screws 16; which move in the openings 17 ofAthe casing 1, as shown.- When the thumb piece 14 is moved forward the contact plate 15 engages the metal plate 12. Connected to the plate 12 is a screw 18 see Fig.9, the head of which secures one end of the electric insulated wire 19; the other end of the wire is connected under the head of the screw 20 of the block of insulation 21. 22- designates another wire, one end of which is connected to the terminal 23 of the battery 2, its other end is connected to the metallic contact plate .24 by means of the screw 25. The terminal 23 may be considered the positive pole of the battery for convenience in tracing the circuits.

Attached to the block of insulation 21'is a metallic plate 26 with which the end of the screw 20 engages to forman electric contact, for one side of the electric circuit. The electric bulb 27 engages, as shown, the plate 24:.

Secured to the block 21, at opposite sides "of the same, are two spring clips '28 for the the reflector 29 by the threaded thimble 33, as shown, by bending or crimping its opposite ends.

The block 21 is formed with a reduced 1nner end in order to fit into the upper end of the cup-shaped member 6 when the parts are assembled as shown in Fig. 2. In this position the wires 19 and 22 are coiled on the reel 34.

For the purpose of preventing the block of insulation 21 from being rotated when the parts are assembled, a pin 35 enters a recess 36 in the upper end of the cup 6 (see Fi 9). 4

Kttached to the upper threaded end of the casing 1 is the connector piece 37 on its upper edge 38 rests the outer flangepart of the reflector 29. 39 is a cap part whlch s threaded onto the connector piece 37. Thls carries the usual glass lens 40.

For temporarily attaching the lamp casing. to the person, or user, a loop 41 is provided. This is designed to engage a button or buckle of the apparel of the user, whereby he may have bothv hands free for use.

Located on the under side-of the rotatable piece of insulation 9 is a plate 42 (see Figs. 1 and 2). This plate is electrically connected to the screw 11, which as shown, is

threaded through the casing 1, that is the negative side of the battery 2. The purpose of this plate is to provide means for making a ground test, by placing a fuse for example, between the plate 42 and .the reflector 29 which includes the two sides or terminals of the battery.

The improvement is used as follows: When the thumb piece 14 is moved forward the plate 15 will close the circuit by engaging the plate 12, and closesthe circuit through the wire 19, screw 20, plate 31, lamp 27, late 24, wire 22 to the other terminal of t e battery. It is now used as an ordinary flash lamp. WVhen the loop 41 is attached to the person so that both hands can be free to use,the lens 40 is removed permitting the lamp 27 and its reflector and the block 21 of insulation to be removed from the cup shaped insulating member as shown in dotted lines in Fig. 2. The wires 19 and 22 permit the lamp to be placed near the work.

When used as a ground or fuse tester the part to be tested is connected or inserted between the plate 42 and the metallic casing 1 whereb the circuit is closed through the lamp 2; causing it to glow if the part, as a fuse,is in perfect condition. If there is an open circuit the lamp will fail to glow.

What I claim is:
