EMERGENCY-LAMP AND BOX THEREFOR.
Application filed December 30, 1914.
To all whom it may concern Be it known that I, Isroon GOLDBERG, a citizen of the United States, and a resident of the city, county, and State of New York, have invented a new and useful Improvement in Emergency-Lamps and Boxes Therefor, of which the following is a specification.
The object of my invention is to provide a device of this class in which a lamp will always be ready for instantaneous use and in sight, and yet so placed that it is not in a position where it will be disturbed under normal conditions, sothat the lamp isalways available for an emergency, and not otherwise. This object is accomplished by my invention, one embodiment of which is hereinafter set forth.
For a more particular description of my invention, reference is to be had to the accompanying drawings, forming a part hereof, in which Figure 1 is a front elevation of my improved device. Fig. 2 is a sectional view,
' taken on the line 22 of Fig. 1, looking in the direction of the arrows. Fig. 3 shows a detail of the lamp partially in section.
Throughout the various views of the drawings, similar reference characters designate similar parts.
My improved safetydevice 1 comprises a box 2 with a cover 3 mounted at one side on a pair of hinges 4 and secured at the other side by means of a suitable lock (not shown) from which the key 5 protrudes so that, under normal circumstances, the box 2 may be locked. This box may be secured in an elevator or other place where the safety device is to be used. The cover 3 has a glass 6 held in the conventional manner and so made that it may be readily broken whenever the lamp 7 is to be found and used.
The lamp 7 is mounted on the back 8 of the box 2 and held between suitable lugs or brackets 9 and 10, the former being at the bottom and the latter at the top. All brack- Gopies of this patent may be obtained for-five cents each, by addressing the Washington, I). C.
Specification of Letters Patent.
Patented July 27, 1915.
Serial No. 879,650.
ets have felt 11 on the faces adjacent to the lamp 7. The box 8 is also provided with a lug 12 of insulating material which passes through alamp 7 and holds the spring 13 and the lamp away from a contact 14; while the lamp is held between the lugs 9 and 10. Immediately uponthe removal of the lamp 7 from these lugs the spring 13 springs against the contact 14 and thereby closes a circuit through the glow-lamp 15 and battery 16 so that the filament of the glow-lamp is heated to incandescence and the light glows, and continues to glow, until the battery is exhiLHSteCl, or the lamp is returned to its proper p ace.
In view of the foregoing, the operation of my improved device will be readily understood. When in place, as shown in Fig. 1 and Fig. 2, the lamp does not glow, but when the glass 8 is broken and the lamp is removed the lamp starts glowing immediately because the spring 13 being released from the lug 12 springs to the position shown at 13 in Fig. 1 where it is against the contact 14 and the light then continues to glow until the battery is exhausted or the lamp is returned. The glass 6 is an ordinary window pane which is cheap and can be readily replaced when broken.
Having thus described my invention, what I claim is- In a device of the class described, a box with a glass front and a lamp removably mounted therein, resilient means in said lamp for closing a circuit therein, whereby the lamp may be lit when the circuit is closed and means in said box for causing said circuit closing means to be open while the lamp is in said box so that the lamp will light immediately upon being removed from said box.
