Specification of Letters Patent.
Patented Uct. 2d, 1916.
Application filed June "7, 1915. Serial No. 32,734.
To all whom it may concern:
Be it known that I, JOHN W. LINDNER, a citizen of the United States, residing at Post Falls, in the county of Kootenai, State of Idaho, have invented certain new and use ful Improvements in Adjustable Lamp-Supports; and I do hereby declare the following to be a full, clear, and "exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to new and useful improvements in electric lamp supports, and is particularly directed to the provision of a support wherein the lamp may be adjustably held with relation to its attaching portion.
It is the object of the present invention to provide a lamp support wherein the lamp is held in such manner as to have a free swivel movement about the support, and further whereby the lamp may be extended from the support as desired, so that the device may be positioned centrally to the ceiling of a room, and actuated to position the lamp either centrally in the room or at any other place desired.
It is further the object of the invention to provide such a device which is of comparatively simple construction, and so designed as to be readily associated with the usual rosette from which the lamp cord extends.
With the above and other objects and advantages in view, the invention resides more particularly in the novel combination, formation and arrangement of parts as more fully hereinafter described and pointed out in the appended claims.
Reference is had to the accompanying drawings, wherein similar characters of reference designate corresponding parts throughout the several views, and in which:
Figure 1 is a side elevational view of the improved device. Fig. 2 is a central vertical sectional view therethrough. Fig. 3 is a horizontal sectional view therethrough on the line 33 of Fig. 2. Fig. 4 is a perspective view of the extension arm holding member, and the pivot rings for swivelly mounting-the same. Fig. 5 is an enlarged detail section showing a portion of the device as disclosed in Fig. 2, and Fig. 6 is a perspective view of a tool member used for actuating the device.
Referring now more particularly to the accompanying drawings, 5 designates a conventional type of rosette suspended from the ceiling, and forming the securing means for a lamp cord 6- carrying the lamp 7. The lmproved device comprises a body portion formed of a cylinder 8 of such diameter as to embrace the rosette and secured to the ceiling by a collar 9 fixed on its upper end, and provided with -a lateral flange 10 through which is passed screws 11 engaging in the ceiling.
A memberbarryingextensible arm sections is swivelly secured to this arm section, and to accomplish this the inner edge of the collar 9 is provided with a lateral flange 12, and a collar 13 is secured detachably as by the screws 14 to the body, and has a lateral flange 15, and a pivot ring 16 is rotatably held between the flanges 12 and 15, free rotation of this ring being had through the medium of bearing ball 17 engaging its inner periphery and seated in races 18 formed in the flanges, these balls being nevertheless engageable against the body portion.
A lower pivot ring 19 is held adjacent the lower end of the body by collar members 20 similar to the collar 13 and having associated therewith similar bearing ball 21. Each of these pivot rings has extending therefrom an arm 22 curved to receive an end portion of the arcuate bar 33 which is secured thereto as by the screws 34;. The central portion of this bar is enlarged and provided with an opening 25 in which is secured the outermost of a plurality of telescopically connected arms 26, the smallest and innermost of which is provided at its outer end with a pair of spaced collars 27. The lamp cord 6 is extended downwardly through the body portion, and around the lower edge thereof, and through the telescoping arm section, the cord used in this device being preferably longer than the cord usually connected to the rosette 5. The arm sections are of any desired length, preferably about 2 feet, and are so engaged with each other that their movement to extended position that they frictionally engage to prevent undesired relative movement, and are held to a certain limit of extension to assure a relatively strong structure. The lamp cord frictionally engages. with the in nermost sections so that it may be drawn therethrough, yet is normally held against undesired movement. Thus a relatively simple device has been provided wherein the H Du ' .medium of one of the screws 30 which holds v the lower collar 20 in place.
What is claimed is 1. A lamp support comprising a cylindrical body member, a U-shaped member havingits legs embracing the body member to swingtherearound and its bight projecting from oneside ofthe body member and a lamp support having one end fixed to the bight of the U-shaped member and projecting radially from the body member.
2; A lamp support comprising a cylindrical body member, a U-shaped member having its legs embracing the body member to swing therearound and its bight projecting from one side of the body member and a lamp; support having one end fixed to the bight of the U-shaped' member and project- Gopiei of this patent may be obtained for ing radially-from the body member and a lamp carrying arm, said arm consisting of a plurality of telescoping sections.
3. A lamp support comprising a hollow cylinder body member adapted to be secured to'a cylinder, a U-shaped member provided at the ends of the arms with rings surround ing the body member, flanges on the body member to prevent movement of the rings longitudinally of said body member, said rings being revoluble about said body member, and a lamp supporting arm having one end fixed to the bight of the U-shaped member and consisting of a plurality of hollow telescopically arranged sections whereby a lamp cord may be led downward through the body member and outward through said arm.
In testimony whereof I afiix my signature in the presence of two witnesses.
