GAS AND ELECTRIC-LIGHT FIXTURE.

SPECIFICATION forming part of Letters Patent No. 443,487, dated December 23, 1890. Application filed December 28, 1889. Serial No. 384,770. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES FELTON, a citizen of the United States, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Canopies for Gas and Electric-Light Fixtures; and I do 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, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in canopies for gas and electric-light fixtures; and the object of my improvement is to provide an attachment for a canopy of the class stated which shall obviate the use of set screws or equivalent devices for retaining the canopy in position upon the pipe, said device to be of simple construction, economical. in cost, durable, easily operated, reliable, and efficient for the purpose intended; to which ends my invention consists of the features hereinafter described and claimed.

Since the introduction of the electric light considerable mechanism is attached to the ceiling of the room adjacent to or surrounding the pipe or conduit through which the electric wires pass downward to the chandelier or lamp. This mechanism secured to the ceiling, as aforesaid, is usually protected by an ornamental canopy or shield secured in position upon the pipe or conduit by a setscrew passing through the canopy and the end engaging the pipe, the shield being held in position on the pipe by the frictional contact of the pipe and the engaging-screw. The canopy is adjusted by loosening the set-screw and then moving it to any desired position upon the pipe. It almost invariably happens that the retaining set-screw is not sufficiently withdrawn to prevent its leaving a mark or track upon the pipe as the canopy is adjusted, thereby marring and disfiguring the pipe to such an extent that the question of overcomin g this difficulty has become of importance to furnishers and users of electric-light fixtures.

In the accompanying drawings is illustrated an embodiment of the device by means of which I propose to overcome the difiiculty, and in the drawings Figure 1 is an elevation of a canopy used in connection with my attachment, the attachment being shown distinct from the body of the device. Fig. 2 is a section of a canopy provided with myimprovement. Fig. 3 is an enlarged plan view of the device separated from the canopy. Fig. i is a plan of a section taken through the center of the device on the line a: 41;, Fig. 5. Fig. 5 is an enlarged vertical section taken on the line y y, Fig. 3.

In the views let the reference-n umeral 1 indicate a canopy of the ordinary shape-that is,.approximating the semispherical in general contour. This canopy is large enough to incase the pipe or conduit 2 and the mechanism 3 surrounding the pipe and adjacent to the ceiling 4 of the room. At its bottom the canopy is provided with a hollow rim open on its interior and surrounding the pipe 2 and incasing a ring or suitable filling 6 of some elastic or resilient yielding material, preferably india-rubber, which protrudes through the interior open space of the retaining-rim, as shown at 7 in Figs. 3 and 5. Rim 5 may be attached or integral with the lower part of the canopy, as shown in Fig. 2, or it may be separate therefrom, as shown in Fig. 1. In any event the elastic or resilient ring or filling grasps the pipe 2 sufficiently tight to support the canopyaud retain it in place on pipe 2 at any desired point, at the same time permitting the rim to be easily moved up or down upon the pipe, the elastic or resilient ring or filling forming in elfect a cushion around the pipe, and as it moves up and down thereon having a tendency to polish and keep it bright and smooth.

In adjusting the canopy, if the rim is a part of it, as shown in Fig. 2, the canopy is grasped in the hands or in any other suitable manner and moved up or down at will, the elastic or resilient ring holding the canopy in place in the desired location upon the pipe. If the ring is separate from the canopy, as shown in Fig. 1, the downward movement is accomplished in the same manner by crowding the canopy down upon the rim, while the canopy is elevated by moving the rim upward against the canopy. Where the rim is separated, the
