ERNEST ALSCHULER, OF NEW YORK, N. Y.

BATTERY HAND LAMP.

Application filed November 8, 1920, Serial No. 422,531.

To all whom it may concern: 1

Be it known that I, ERNEST ALsoHULEn, 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 is a specification.

This invention relates to battery hand lamps, and more particularly to means for locating a hand lamp in the dark.

It often happens that the user of a battery hand lamp may set the lamp down or drop it accidentally after extinguishing the light thereof, in which case, it may be difficult to relocate the lamp in the darkness. It is convenient, therefore, to have means .on the lamp which will be visible in the dark so as to indicate the location of the lamp. Such means should, of course, be arranged to be visible from any direction with respect to the lamp and in whatever position the lamp may happen to be resting.

ne of the objects of this invention, therefore, is to provide means for visually locating such a lamp from any direction and irrespective of a position of the lamp.

' Further objects will appear from the following description taken in connection with the accompanying drawing, in Which:

Figure 1 is a view in elevation of a lamp embodying this invention;

Figure 2 is a section on line 22 of Figure 1;

Figure 3 is a section on line 3-3 of Figure 2; and

"Figure 4 is a sectional view similar to Figure 3 but showing this invention applied to a lamp having a metallic casing.

Referring now to the drawing. Figure 1 represents a battery hand lamp of the usual construction having a casing 1 adapted to contain a battery and a lamp, the circuit of which is controlled by a switch 2. Mounted on the casing and uniformly spaced about the circumference thereof, are three or more plugs 3, fixed to the casing by being forcibly inserted into sockets or holes 4 therein.

Each plug 3 has a depression or cavity 5 punched or otherwise formed therein. Within the cavity 5 is deposited a layer of luminous material 6. Said luminous material may consist of any of the many well known phosphorescent or luminescent materials and is preferably prepared by coatmg a disc of paper therewith, which disc may then be inserted into the cavity 5. The luminous material 6 may be provided with a transparent cover 7 made of transparent material such as celluloid or the like, and adapted to protect the luminous disc 6 from 1n ury or deterioration. After the insertion of the cover 7, the edges of the cavity 5 may be burred over to form a retaining flange 8 to retain the luminous material and its cover 1n place. The plug 3, by being forced into the socket 4, is securely held in place.

WVhen the lamp is in the dark, the luminous material 6 will always be visible by virtue of the light radiated therefrom. Smce there are three or more plugs 3 spaced uniformly about the casing 1, one or more of these plugs will be visible in whatever position the lamp may assume. It is, therefore, assured that the location of a lamp dropped or mislaid may be determined from any direction and in any position of the lamp.

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:

1. A battery hand lamp, comprising, a cylindrical battery-receiving casing having a lamp, and a series of luminous elements spaced around said casing, substantially as and for the purpose set forth.

2. A battery hand lamp, comprising, a cylindrical battery-receiving casing having a lamp, and a series of luminous elements spaced around said casing at oneend thereof, substantially as and for the purpose set forth.

3. A battery hand lamp, comprising, a cylindrical battery-receiving casing having a lamp at one end thereof and a series of luminous elements spaced around said casing at the lamp end thereof. substantially as and for the purpose set forth.

In testimony whereof I afiix my signature this 21st day of Aug, 1920.

ERNEST ALSCER.
