ELECTRIC-LAMP SUPPORT.
Specification of Letters Patent.
Patented Apr. 25, 1916.
Application led August 10, 1915. SeriaLNo. 44,819.
To all whom it may concern.
Be it known that I, WILLIAM C. HUMMEL, a citizen of the United States, residing at Hornell, in the county of Steuben and State of New York, have invented new and `useful Improvements in Electric-Lamp Supports, of which the following is a specification.
My invention relates to electric lamp supports and more particularly to a support for suspending a lamp from the ceiling.
The primary object of this invention is to provide a stationary tube and a sleeve movably mounted upon the tube and specifically supporting the lamp carrying tube acting for the sleeve in an adjusted position whereby the lamp supporting tube may be adjusted within the path of an arc at right angles to the stationary tube.
Another object of my invention is to provide a device of this character which is efficient and durable in its construction and which may be manufactured at a nominal cost.
With these objects in view, and others of a similar nature which will appear as the invention is more fully understood, the invention consists in the features of construction and arrangement of parts hereinafter described and claimed, reference being had to the accompanying drawings, in which z Figure 1 is a side elevation of my device showing the side view. Fig. 2 is a central vertical section of the same. Fig. 3 is a transverse section taken on line A-A of Fig. 1. Fig. 4 is a vertical section of a modified form of Fig. 2. Fig. 5 is a detail view of the clamping ring.
Referring to the drawings in detail, 1 designates a canopy of the common form of construction which is suitably attached to the ceiling of a room and is provided with an annular collar 2 surrounding the opening in the canopy, said collar being internally threaded to receive the threaded end of the stationary tubular member 3. rllhe tubular member 3 is vertically arranged within said collar and depends therefrom, the lower end of said tube having its adjacent side wall exteriorly threaded to receive a cap 4. This cap is provided with a central opening which communicates with the interior of the tube 3.
Mounted upon the tube 3 and capable of vertical movement thereon is an annular sleeve 5, the outer side wall of which is provided with a pair of laterally extending arms 6. These arms 6 are arranged in par allel spaced relation, each of which is provided with a transverse opening 7 adjacent the outer end, said openings 7 being arranged in registration with each other. Supporting the sleeve 5 on the tube 3 is a clamping ring 5 which is of a substantially U-shaped configuration and has its upper edge fiared outwardly to form a substantial support for the sleeve 5.
8 designates an annular collar which is provided with an upwardly extending ear 9, said ear being provided with a transverse opening therein. Passing through the openings in said arms is a pin 11 upon which the ear is pivotally mounted, the ear being of such a lwidth as to frictionally engage the confronting walls of the arms 6. The inner Wall of said collar 8 is internally threaded to receive the threaded upper end of the tubular member 12. The lower end of this tube 12 isl externallyl threaded to receive a cap 13 which is provided with a vertically disposed opening adapted to pivotally receive the upper end of an electric lamp socket 14. The walls of the opening in the cap 13 are provided with registering transverse openings which are adapted to receive the pins 15 which have the confronting extremities threaded within the lamp socket 14. The lamp socket 14 is provided with the usual internal threads which receive the lamp 16. Connected to the lamp 16 is the usual electric conductor cord 17 which eX- tends upwardly through the socket 14 and the tube 12 and out at the upper end of the tube and is then trained down through the lower end of the tube 3 and upwardly therethrough to the usual leads which are located within the wall.
From the foregoing construction it will be seen that when it is desired to vertically adjust the tube 12, upon the stationary tube 3, the clamping ring 5 having been removed, the operator is at liberty to vertically move the sleeve upon the tube. Having placed the sleeve in its desired position, the clamping ring is then inserted upon the tube beneath the sleeve, thereby supporting said sleeve and holding the lampcarrying member in the corresponding position. The opposite ends of the tube 3 being provided with projections formed by the collars 2 and the cap 4, the sleeve 5 is locked upon the tube and any accidental displacement of the same is prevented. If it is desired to elevate the lamp 16 upon the sleeve 5, the
i tube 12 may be moved outwardly and lupwardly owing to the fact that the upper end of the tube is pivotally mounted within the parallel arms 6. The factthat the ear 9 frictionally engages the side walls of the s Aarms,.permitsthe tube 12 to be rigidly held any position upon its support. The lamp socket 14 being p ivotally mounted within the'cap 13 permits the lamp to be swung to anyv angle thereby obtaining the maximum amount of light from the lamp.
In Fig. 1L I have shown a modified form of the tube 12 vcomprising the two telescopic " members 17 and 18 respectively, -17 being sleeve, parallelfspaeed arms formed on said sleevejand extending laterally therefrom, a lamp supporting tube, an ear formed on one end of said tube and pivotally mounted bef tween said arms, the sides lof said ears frictionally engaging the inner faces of the arms.
2. A lamp support comprising a tube, means for suspending said tube, a sleeve movable on said tube, a clamping ring mounted on said tube and supporting saidsleeve, parallel spaced arms formed on said sleeve and extending laterally therefrom, a second tube, an ear formed on one end of said tube and pivotally mounted between said arms, a cap formed on the lower end of said last mentioned tube and having an openingformed therein, a lamp socket pivotally secured to the inner wall oi' said opening, the outer wall of said socket adapted to frictionally engage the inner walls of the opening of said cap.
3. A lamp support comprising a tube, means for suspending said tube, a sleeve movably mounted on said tube, a clamping ring mounted on said tube and supporting said sleeve, parallel spaced arms formed on said sleeve and extending laterally therefrom, a second tube pivotally mounted between said arms, and a lamp supporting tube telescopically mounted within the last mentioned tube.
In testimony whereof I afix my signature in presence of two witnesses.
