UNITED STATES ERNEST ALSCI-IULER, OF NEW YORK, N. Y.

BATTERY HAND LAMP.

Application filed June 21, 1920. Serial No. 390,511.

To all whom it may concern." 7

Be it known that I, ERNEST ALsoHULER, a citizen of the United States, and residing at New York, New York, have invented the new and useful Improvement in Battery Hand Lamps, of which the following isa specification;

This invention relates to battery hand lamps of the type adapted to be lighted while held in the hand by the manipulation of a switch on'the casing, and more particularly to such lamps as are provided With an all metal casing; I v

As such lamps areoften carried in tool boxes and similar places and accidental contact is liable. to operate the switch, thereby lighting the lamp-and exhausting the battery unnecessarily, it is'desirable to provide means for rendering such accidental exhaustion of the'battery impossible. One of the objects of this invention, therefore, is to provide means for obviating the danger of accidental closing the battery cir- .cuit by manipulation of the switch.

,Another object of this invention is to provide novel means for insulating the interna circuit conductors. r t

Another object of this invention is to provide a lamp structure which is simpleand cheap to manufacture and reliable in operation. y

Further objects will appear from the detailjdescription taken in connection with the accompanyingidrawings in which Figure 1 is a sectional view of a battery hand lam embodying this invention;

Figure 2 is an enlarged detail view showing the structure for supporting the reflector; 1 V

. Figure 3 is an enlarged detailview showing the construction of the auxiliary circuit opening device; and, V a

Figure 4 is aview showing the end cap partlyrunscrewed'so as to open the battery circuit. r a 1 Referring now to the accompanying drawing, 1 designates the metallic casing, 2 the battery,"one of whose terminals contacts with one of the terminalsof the lamp 3, mounted in the-reflector 4 inthe usual way The upperend of the casing 1 is threaded to receive athreaded sleeve on the housing 5, which encloses the reflector. The

upper end of: the reflector bears against the a lower face of a lens 6, which is held place by. the ring 7, screwing on to the upper end of the housing 5. These parts'may be of the usual construction well known in the art.

The housing 5 is bent inwardly to form an internal annular shoulder as shown at 8. A metallic ring 9 is mounted on the shoulder 8. The ring 9 is formed to receive and re, tain an insulating ring 10 which is arranged to engage the reflectoreat an intermediate portion thereof,-so as to support and center said reflector in the casing. The outer end of the reflector may be of smallerdiameter than the ring 7, so as to be spaced therefrom for insulation. purposes. The reflector 4 is securely held in position by being confined between the ring 9 and the lens 6.

The switch 20, which may beof the construction described and illustrated in No. 1287262, of December 10, 1918, is mounted on the casing and in electrical connection therewith. This switch; has contact 11 in: sulatedfrom the casing. A- conductor 12 passes upwardly within the casing'being attached near its upper end by means" of a rivet 13 to an insulating collar litmounted in the upper end of the casing, and adapted to support and insulate the conductor 12. Said conductor extends beyond the casing a suiiicient distance to contactwith the refleet-or, passing inside of the ring 10, The

conductor 12 is insulated from the casing by means of an insulating. strip 15 which is attached to the casing. by means of the rivet 16, and the conductor 12 is attached to the strip 15-by-means of the rivet 11.

A perforation 17. in thecasingis adapted to insulate the rivet .11 therefrom and a similar perforation. 18*inthe conductor 12 is adapted to insulate the upper rivet 1 60 fromsaid conductor. V

A metal end cap 19 of theusual construction is provided to close the lowerend of the casing. Within the :end cap, but insulated therefrom, by means of thefianged insulating washer 21, is ametal disc 22. having an overturned flange23 adapted to receive and retain a coil of thebattery sup,- porting spring 24am thef-battery. circuit. The flange 23 is arranged, to ron'ta'ct' with the flange 25 in the end ofthe casing to complete the batterycircuit. l

It will beseen that when the unscrewed so as to break contact between the flanges 23 and 25, it will be impossibleto close the battery circuit by manipulation of the switch 20.

It will further be seen that by means of the ring 10 and the insulation 14 and 15, thatthe upper branch of the lamp circuit is entirely insulated from the casing, so that by breaking contact between the flanges 23 and 25 the casing is entirely insulated from the battery circuit. It will also be seen that when the housing 5 is screwed home upon the casing that the conductor 12, which passes up inside of the insulatingring 10, will be brought into forcible contact with the reflector 4 and will be sustained insuch contact by the ring 10. w

It'will be seen, therefore, that this invention accomplishes its objects by providing a construction whereby accidental closing of the battery circuit may be rendered impossible. It will also be noted that novel means are provided for insulating the internal circuit conductors from the casing. It will further be seen that the reflector support is'of such construction as to effectively support and fix the reflector.

It is obvious that various changes may be made in the details of construction without departing from the spirit of this invention;

it is, therefore, to be understood that this invention is not to be limited to the specific details shown and described.

Having thus described this invention, what is claimed is:
