J. NPLE. ELECTRIC LAMP SUPPORT.
APPLIUATION FILED JAN. 3, 1910.
` INVEMTOR` .JOSEPH NPLE, or LYON, FRANCE.
To all whom t muy concern:
Be it known that I, JOSEPH NPLE, a citizen of the French' Republic, residing at Lyon, in France, have invented certain new and useful Improvements in Electric-Lamp Supports, of which the following isa specification. j
This invention relates to a support-ing vdevice for electric lamps whereby they may be tion perpendicular to their' normal position.`
inclined in all directions including a ldirec- The annexeddrawing represents an --embodiment of the invention by way of` example, Figure 1 being an elevation showf ing an electric lamp provided with the improved support, and Fig. 24 is a plan'view of the supportdetached. 1
The im roved support comprises a plate A in the orm of a cross, the central portion of which is provided with a circularaperture through which the lamp holder B passes,
the usual threaded rings C and D of the la'tter fixing the holder to said plate. The/four outer ends of the plate A are turnednpward. at approximately a right angle at Aleand, then diametrically opposed extremities are `respectively connected totwo semicircularly curved members E and F constituting slides which can each rotate about two pairs of rivets e e and f f connecting them to theends A1 of the plate A and which thus serve .as pivots. The two Amembers E and Fare thus disposed in planes perpendicular to one another, and passing through apertures El, F1 withv which they are provided for approximately their entire length is 'a union y G adapted to. be fixed to a suitable support. The stem g of the union which is engaged -between the members E and F is of square s'ection and slides with slight friction be `tween the lateral members of said members in such a manner as to prevent the lamp falling by gravity when said lamp has been moved into an inclined position. The current is conducted to the lamp H by means of flexible wires I which traverse the union G andare connected to the holder in the usual 'manner'. The said wires are thus connected at the center of support which insures their preservation and renders them substantially invisible.
rBhe construction describedwhereby the two membersE and F are rotatable about two axes perpendicular to one another constitutes. a' method of articulation enabling.

the lamp to be moved in all directions by causing the plate A to pivot about one of the axes e e or f f or about both 'simultaneously.v
Fig. l` of the drawing shows in broken lines the lamp assuming an inclined position. In the movements described the members E and F are displaced relatively to the union G, the distance from the latter to the holder, however, remaining zonstant, so that as traction is exerted on the wires I and ,owing to the length of the apertures El and F1, it is possible to cause the lamp to move through a-` complete semi-circle in all directions and toset it horizontally or in any `direction desired.
The plate A is also adapted to support Aany form of lamp shade. In' the form shown, `for this purpose the vcentral part at 4each end of an arm of said plate is stamped out 4and turned downward to form lugs a through which are threaded screws K engaging the groove jof the shade J in the usual manner.`
. What I claim as my invention and desire to secure by Letters Patent of the United States is 1. An electric lamp support comprising a base, ltwo pairs of diametrically opposed pivots carried thereby, one pair being in a plane perpendicular to the other, a slotted member rotatableabout each pair of pivots, and a union engaged by said slotted members at r said base, and a lexibleconductive connection between said union and holder.l
3. An electric lamp support comprising a baseof cruciform shape,I two pairs of diametrically opposed pivots carried by the ends of the arms of said base, one pair of pivots being in a plane perpendicular to the ,other pair, a pair of semi-circular slotted f members each rotatable about a pair of said pivots and intersecting each other, and a union engaging and held in the slots of said members at the intersection thereof.
4. An electric lamp support comprising a base of cruciform shape, two pairs of diametrically opposed pivots carried by the ends of the arms of said base one pair of pivots being in a plane perpendicular to the other pair, a pair of semi-circular ,slotted members each-rotatable about a pair of said pivots and intersecting each other, a union engaging and held in the slots of said mem- `bers at the intersection thereof,` a lamp holder carried by said base and a flexible conductive cnhectin between said union 10 and holder.

In Witness whereof- I have signed this specification in the presence of two Witnesses. o
