COMBINATION FLASH-LIGHT AND CIRCUIT TESTER.

, Application led Junel29,

My invention belongs to that general class of devices known vas Hash lamps or lights and relates more particularly to a combined flash light and tester, which fis convenient for use by electricians, mechanics, motorists andthe like, for testing fuse plugs, electric light wiring, ignition wiring and generally as a trouble shooter, as well as a simple andL convenient trouble light or the like for the 10, purposes for which flash lights are generally characters indicate like or corresponding parts,

Fig. 1 proved device; f

Fig. 2 is a view of one of the contacts, showing a no-vel form of protecting cap;

Fig. 3 isa similar view showing another type of cap; and

Fig. '4; is a similar view illustrating another type of protecting cap. Referring to` the drawings, in which the preferred embodiment of the invention is shown, I have illustrated a Hash lamp similar to those in general use, it being understood that the details of the lamp construction and battery container may be modified without departingfrom the general construction of. my improvement. l v f y s shown, 1 represents a casing of suitable material such4 as metal, provided with an end cap 2 which is preferably removable and with a threaded flange 3 arranged to receive a lens retainer 4. Arranged within the casing is the battery 5 consisting of one or more cells, depending upon the size and design of the casing, which need not necessarily be cylindrical as shown. The particu-v lar casing 1 shown is of metal and may therefore be used -as one of the conductors or contacts, the same being electrically con- Cal is a sectional view through my i111.-

nected with the battery by the spring 6, which also maintains the battery against displacement and against one of the terminals of the lamp. The opposite end of the battery is 'provided with the usual terminal 7 G0 arranged to contact with the terminal 9'on the lamp 8, the shell 10 on the lamp .also serving as a conductor, it being understood that the terminals 9 and 1() are connected with the lamp filament, The lamp as shown G5 l is arranged to be carried by the reflector member 11, which may be insulated from the casing by the insulating member 15. I have shown a lens v12'secured in place by the y retalner 4, the lens also serving to secure the reflector in place. There is provided a `switch member 14 arranged to be controlled from the exterior of the casing by vthe button or slide 13.

When the slide` is moved up member 14 contacts with the 75 reflector which is in electrical contact with the shelh 10, thereby closing the circuit and causing the lamp to be lighted, thereby indicating that the battery is alive,

as well as permitting the lamp to be used for 50 lighting purposes.

There. is in addition provided one or more terminals which are normally a part of an open circuit against which a device to bey tested maybe placed, closing the circuit and -causing the lamp to be lighted, thereby indicating a closed circuit through the device to be tested. In the particular device illus- K trated, the'casing being o-f metal, it is necessary to provide only one Contact, the metallic casing itself serving as acontact and obnductor. As shown, I have provided a contact member 17 which is suitably insulated from the casing, but which is provided with a stem 18 extending to the interior of the/cas- 05 ingv and which carries a spr-ing or contact member 19 arranged to contact with the rel'ector shell or the shell 10 on the lamp. The particular contact shown is insulated from the casing 1 and washer 20by insulation 21. 100 J In order to prevent the accidental short- .circuiting of the terminal 17 withthe casing,

as for example when the lamp is in -a tool box or the like, I have shown in Fig. 2 how a rubber cap 25 may be positioned over the 105 same except during such time as the lamp is used for testing purposes. If desired, the part 2O may be slightly reduced, as indicated at 26, so that the rubber cap is firmly held in place. A piece of rubber tubing may 1.10

be provided for the same purpose if desired. In Fig. 3 I have illustrated a metal or fiber cap 27 which may be internally screw threaded and arranged to 'engage a thread on 20 corresponding to 20. In Fig. 4; I have illustrated how a sliding cap 28 might be arranged on the device for the same purpose.

From the preceding it Will be obvious that I have provided a tiash lamp which may be used in the ordinary manner for the usual purposes, but which may also be used for testing purposes Without in any Way affecting its use as a lamp. I'have also provided a construction that does not involve a radical departure l'rom the present well known types vhence I do ndt Wish to be understood as limiting myself t`o the exact form, construction,

arrangement and combination of parts herein shown and described, or uses mentioned.

What I claim as new and desire to secure by Letters Patent is:

The combination with a flash light having a control switch, a metallic casing, a metallic reflector insulated from the casing and adapted to engage a terminal of the lamp, of a contact member having 'a stem projecting through the casing, a washer on the stem tapering inwardly toward the casing, insulation between the stem and Washer and between the cont-act and Washer, resilient means at the inner end of the stem engageahle with the retlector to form a circuit with the lamp for testing purposes, and au insulating shield fitted over thc contact member with its inner portion contracting over the tapering portion of the washer to prevent accidental displacement of said shield;

In testimony lwhereof, I have hereunto signed my name.
