UNITE sinne rafrnrrr FICE.

wrLLiaran. encre, or New Yoan,l N. Y.

PORTABLE Laia?. l

city and State of New York, have invented a certain new and useful Improvement in Portable Lamps, of which the following is a specification.

My present invention relates to an improved portable light especially useful for lighting written or printed music while playing the piano, or in other locations where it is desirable to direct a suflicient reading light upon a page without hiding the same from the reader, and While keepingr .the light out of the eyes of the reader.

My. improvement provides means for this end which are capable of being made very sightly and are very compact and convenient for packing away or carrying about. Whenv not in use my improved apparatus may be so closed up as effectually to protect the lamp,

The invention is shown in a preferred form in the'. accompanying drawings, wherein- Figure 1 is a perspective view of the entire device in use, Fig. 2 is a plan view of l the same with the cover removed, Fig. 3 is a bottom plan View of the moving` parts, and Fig. 4 is a side elevation of a modifica-- tion.` A' v My invention comprises a suitable conf tainer for a battery, 'a lamp, a movable sup- Aport for the latter carried by the container and circuit closing means so arranged that, when the lamp is brought into useful position, the battery is made to supply the current whiclrlights said lamp.

In the drawings the -container takes the form of a' box 10, having a cover 11, within which are laid two large dry cells 12. One end of the box is cut out, as at 13, to pro` vide an opening of suitable shape to admit the lamp and reflector when the entire device is to be closed up when not in'use.

The incandescent bulb 14 is contained within a reector 15, hinged as at 16 and 17 to the outer end of a sliding bar 18. The inner end of this bar is arranged to slide in under and between the cells 12, when the device is closed up, and it is confined andguided between cleats or guide blocks 19, Q-O. These blocks carry knife-switch contact pairs 21, 22,'as shown in Fig. 2, which are permanently connected 'with the opposite terminals of the battery.

Contactplates, 24, are firmlyixed t0 opposite sides of the bar 18, in such a position that, when the barl is fully drawn for-4 ward, these plates enter the contact pairs 21, 22, the plates 28, Q4, are electrically con! nected by

wires

25, 26, to the separate hinges 16 and 17 (see Fig. 3) and these latter are respectively connected to the opposite ter! minals of the lamp 14. The cleat 27 holds the bar 18 in plac'e between the guide blocks.

When it is desired to extinguish the light it is only necessary Ato push in the bar 18- far enough to break the circuit at the switch terminals 23, 24. The reflector can be turned pp into the position shown in dotted lines in Fig. 1.; and, the bar 18 being pushed home, the reflector is passed into the opening 13, thus closing the device. The shape.

of this opening 13 is preferably such as just to admit the reiiector, which then serves to act as a door or lid for said opening.

It will be' seen that a device of this kind can be set down on the top of an upright piano, for instance, and, by drawing out the bar and turning down the reflector, as shown in Fig. 1, a bright light is thrown exclusively upon the music rack, the performers eyes being shaded, while, at the same time, the lamp and shade do not interfere with a clear view of the page.

. In Fig. 4, for instance, there is shown a structure whereby the lamp circuit 1s closed finally by turning the lamp and reflector down into reading position. For Vthis pur- Specication of Letters Patent. l Patnte Fell), AQ2, 1916, .application ined April 2o, 1915. seriainaaaeaa pose the two

wires

25 and 26 are connected,

one to av spring 28 and the other to the hinge-29. Onelamp terminal is connected to the hinge and the other to a Contact piece 30. 'When the reflector is turned down, as shown, the lamp is lighted by Contact between E28 and 30.

It will be seen that in my apparatus there is provided a portable self-contained means1 capable of.placing, for instance, on the top ofl an .upright piano; and wherein the bat-v teries serve not only to provide current, but as counter-weights permitting the lamp to be drawn far forward without danger.

What I claim is: v

1. A portable lightinfr apparatus comprising in combination a container having a forward opening, weighting batteries therein, a bar adapted to be slid completely within said container or outward through said opening at will, an electric lamp pivotally supported upon the outerend of saidbar,

a switch operated by movements of said bar, and appropriate electric connections between said Switch, and battery and said Switch and lamp substantially as described.

2.'A portable lighting apparatus comprising in combination a container having a forward opening,l Weighting batteries therein, a bar adapted t0 be slid Completely within said container or outward through said 10 opening at will, an electric lamp and re- Copies of this patent may be obtained for Hector pivotally supported on the outer extremity of said bar, said reiiector being so shaped as to be adapted to close said opening when tilted upward, a switch operated by movements of said bar, and appropriate electric connections between said switch and battery and said switch and lamp, substantially as described.
