s. W. BAILHAGHB. ELECTRIC LAMP SUPPORT. APPLICATION FILED JUNE Z, 1809.

/C/a. Z

. Patented June "i, 191D.

To "all wlzmntima-y concern:

a citizen ofltheifUnited'States, residingat Vallejinfin the'county of- Solano and Slate of-LCalifornia, have invented new and useful Improvements in Electric-Lamp Supportsf, of which the following is a, specification.

The object of theiipresent invention is to provide a lamp support for electric'lainps which will enable the lamp to illuminate music Asheets for bandsmcn or other inusicians when` playin@ at night out of doors, as in a. parade. il lamps are at; present used for this purpose, but the illumination ali'lorded thereby is irregular and uncertain, and, moreover they may become objectionable by smoking or from the smell of the oil. The present invention avoids these ob,- jections.

In the accompanying drawing, Figure 1 is a perspective View illustrating the device in use; Fig. 2 is a longitudinal section of the device; Fig. 3 is a top plan view.

Referring to the drawing 1 denotes an electric incandescent lamp having a screw plug 1a engaged with a screw cup or socket 2. The shell or body portion of the socket; forms one terminal of the circuit and it is electrically connected to a contact plate 8 which projects laterally from said socket and has at its ends a contact head 9. The lamp socket 2 is carried by one member 3- of a. t-wospartclasp, the other member-150i which is similar in construction, and the two members are pivotally and resilient'ly connected by a wire spring 16 of a common forni. r1`he clamp members or sections 3, 15,

are constructed oi: wood or other non-conducting material and they are in the forni of strips or blocks having fiat faces and provided at one end with opposing beveled faces 1Gal to forni linger pieces at said end. The opposite ends of the clamp members 3, 15, have their opposing faces beveled as shown at- 16", an( recessed as at 16 to form opposing jaws adapted to be engaged with a music sheet 17 which is carried in the usual manner on the niusical instrument- 1S. The inner terminal or pole ol' the lamp socket is in the foi-m of a sere-w f1 which passes through the clamp member 3 and has its inner end united to a longitudinally arranged contact strip or plate .3 set in the inner face of the. clamp member 3, as shown in. Fig. 2. The other end of the contact strip 5 is Parana or gfiml-G-ls..A 'L' isiieciticatioiiloiietti'sa ent'llw`- 1 l v Application filed June?,` 1909. fSeral 'Nog 499,791, l

binding-post 6, which latter exber3. and hfson." its outer end a washer and a thumb nutl 6, beneath which latter is clamped fonc of:theconductors'of an electric circuit-112'. The other conductor of this circuit is similarly clamped beneath a thumb nutz-11a on a" binding post 11, which latter passes throud'h `theiclamp member 3 adjacent=itsio tlierge1idor:linger piece. 1

0n t-lie binding post- 11 between `the clamp lncinbcr and its thumb nut are washers 11, between which latter is arranged a swinging or pivoted switch plate 10 of resilient material adapted to be engaged with and disengaged frointthe contact head 9. The switch plate 10 swings from the binding post 11 and on its free end is provided a `tti-nger piece or stud 10a covered with insulat.:

g ing material, as clearly shown in Fig. 2.

For the purpose of reflecting the lightof the lamp downwardly upon the music or sheetl 17 and keeping the direct rays of light out of the musicians eyes, a reliector 14 is Vprovided for the lamp. This retiector has an enlarged, concaved or seinispherical portion at its outer end to suriouiid the bulb of the lamp, and its reduced inner end is bifurcated to straddle the contactstrip 8 and the clamp member 3, and to provide spaced side lugs 14ea which engage. the opposite side edges .of said ineml'ier 3 and are secured thereto by screws or staple fastcnings. 'lhc two conductors 12 of the circuit have their opposite ends united to the binding posts on a pocket battery 13 which as shown in Fig. 1, is carried in the outer side pocket of the musician. In practice, however, this battery will be carried in one of t-lie inside breast pockets of the user for obvious reasons.

From the foregoing it will be seen that the invention provides an exceedingly siniple and handy device which I have found in practice to be exceedingly el'ect-ive. The peculiar construction of the device renders it inexpensive, light' in weight, but at. the saine t-inie strong alid dur-able, and the arrangement of the switch 10 on the clamp enables the light to be readily-#turned on and ot'l', thereby saving the battery, it being well known that the life of an ordinary pocket;

battery is very short, and that they materi' a switch .which may be carried by the batf tery. The peculiar construction of the clamp renders itexceedingly light, and at the same time causes the lamp to be held firmly and securelyon the music so that the light given off by the lamp will be steady and brilliant.

I claim:

The combination of` a clamp composed of members of non-conducting material pivotally connected by a spring intermediate their ends and having finger pieces at one end and jaws at the other, anelectric lam a lam of said clamp member, a'binding post. ex-

tending transversely through the last mentioned clamp member, a pivoted switch plate 20 on one of said binding` posts movable into' and out of engagement'with `said contactstrip, -a screw arranged transversely 1n the last mentioned clamp member and forming the inner pole of the lamp socket, a contact. 25

late unitlng said screw and the otherbindmg postand secured to the inner face of the last mentioned clamp member, and a reieotor for the lamp and having its inner end bifurcated to-straddle said contact strip 3o and the clamp member which carries it.

In testimony whereof I have hereunto set my hand in the vpresence of two subscribing Witnesses. i
