FUKUTARO YOKOYAMA, OF TOKYO, JAPAN.
ELECTRIC POCKET LAMP WITH SIGNAL PANE AND COMPASS.
Application filed December 19, 1919. Serial No. 346,001.
T all whom it may concern:
Be it known that I FUKUTARO YoKo- YAMA, a subject of His Majesty the Mikado of Japan, a resident of Tokyo, Japan, have invented new and useful Improvements in Electric Pocket Lamps with Signal Panes and Compasses, of which the following is a specification.
This'invention relates to an electric pocketlamp containing a signal-pane or a compasscase set between a lens and a lamp-bulb or hid on the inside wall of a cap by turning and removing a spring-bar put to inductive metal fittings on the inside of the cap flat- 1 formed with a broad periphery and fixed with a lens in the middle of the surface. At the end of the elastic part of the spring-bar a coloured pane or compass-case is fixed.
The objectsof this invention are to be used as substitute for signal-lamp under the shortest construction and also to favour with orientation at night, so that it is handy to carry at travelling with my lamp.
Referring to the drawings, which form part of this specification, Fig. 1 is a vertical section and Fig. 2 a section through AB at Fig. 1; like letters refer to similar parts throughout the drawings.
In this invention a dry battery (2) is detachably inserted in cylindrical case (1), at lower end the capsule l) taking in a spiral spring filliping up the dry battery (2) is screwed inwardly. At the upper end of the case (1) is put a reflecting pane (6) screwed with a bulb (5) in the center and also in the upper part, on the outside of this lamp a switch is prepared.
The composition above have no distinction from that of general pocket-lamps. Notwithstanding in this invention midst in the surfaceof the cap (8) flat-formed, having a broader periphery than the diameter of the case (1) the lens (9) is put in fixedly and on theinside wall of the cap a inducting groove (10) is cut into and the lower end of the cap is screwed to the upper of the case (1). On the inside wall of the cap (8) the inductive metal fittings (l1) put in with the springbar (12) turned up in the middle bifoldly is The one part of it (12) is curved arch-wise for touching the inside wall of the cap and at the end of this one part are set legs of the knob (13) enabled to jut out into the outside of the inducting groove The other elastic end of the bar (12) is curved to jut out into the right under face 'of the lens. At this end is fixed a signalspring-bar (12) to the inside wall of the cap (8) and thereby the coloured signalpane is set between the lens and the bulb or the pane is hid by approaching to the inside wall of the cap to signalize freely, changing with the red, blue or white light and if the compass-case should come forth to the right under-face of the lens, there is an orientatlon easy even at a dark night, looking on the indication of magnetic needle.
In this invention, in case the surand under-face of the compass have coloured panes, the colour of the one signal-pane is different from that of the other pane, so that two coloured signal panes and compass may be used here at the same time.
I claim:
spring.
