Application August 12, 1939, Serial No. 289,805

1 Claim.

This invention relates to ceiling and wall lighting fixtures of the rosette type, and has for one of its objects the provision of a lighting fixture of this character in which the receptacle portion of the fixture is secured in place internally of the fixture and without the use of unsightly locking rings or nuts now commonly used.

Another object of the invention is the provision of a lighting fixture of the nature referred to, comprising a disk preferably made of a plastic material, and provided with a central boss integral with the disk, said boss having a threaded opening which is adapted to receive the threaded end of the receptacle for securing same in place from the rear of the disk.

A further object of the invention is to provide the said boss with a reduced or undercut portion upon which may be supported the globe or lamp shade holder.

A still further object of the invention is the provision of means for securing the said fixture to the outlet box, said securing means not being visible from the front of the device.

Up to the present time, lighting fixtures of the rosette type were made in the form of a disk having a central perforation through which extended the threaded portion of the receptacle which was held or locked in place by a threaded ring at the front of the fixture. This construction entailed extra parts and labor and the threaded ring would often become loose and seldom if ever matched the color of the disk, thus giving to the fixture an unsightly appearance. To obviate these undesirable features, I have perfected by improved lighting fixture.

Another object is to produce a device of the character described in which the maximum simplicity of construction and operation is secured.

Other objects and advantages will appear as the nature of the improvements is better understood, the invention consisting substantially in the novel arrangement and co-relation of parts herein fully described and illustrated in the accompanying drawings, wherein similar reference characters are used to describe corresponding parts throughout the several views, and then finally pointed out and specifically defined and indicated in the appended claim.

The disclosure made the basis of exemplifying the present inventive concept suggests a practical embodiment thereof, but the invention is not to be restricted to the exact details of this disclosure, and the latter, therefore, is to be understood from an illustrative, rather than a restrictive standpoint.

In the accompanying drawings Fig. 1 is a sectional view of one form of my improved single lamp rosette. i

Fig. 2 is a top plan view thereof Fig. 3' is a front view, partly in section, of a modified form of my improved rosette, and

Fig. 4 is a top plan view thereof.

Referring now to Figs. 1 and 2 of the drawings, 5 indicates a dished plate or disk which is preferably made of any suitable plastic material of any desired color and which is provided with a central boss 6 having a cylindrical opening 1 provided with inner threads 8 adapted to receive the metallic screw-threaded end 9 of the electric lamp receptacle l which is connected, by means of wires II and I2, to the wiring in the outlet box (not shown). The disk may be provided with ribs [3 and I4 through which pass the securing screw-holes l5 and I6 and locating or positioning dowel pin-holes I1 and I8.

The boss 6 has a reduced portion l9 and an enlarged portion 20 to receive any suitable lamp shade supporting means used in connection with such lighting fixtures, such shade supporting means not being shown as it forms no part of this invention.

In Figs. 3 and 4 I have shown a modified form of the invention, wherein the disk 5a is provided with the centrally perforated and innerly threaded boss 6 to receive the threaded end 9a of a somewhat modified receptacle Illa to which is secured, bymeans of screws 2|, a strap 22 having screw clearance holes 23 for the reception of screws S, one of which is shown at the right of Fig. 3 for securing the fixture to the outletbox, not shown.

In this form of the invention the strap 22 carrying the receptacle low is first secured in place and then the disk 5a is threaded onto the threaded lamp socket portion 9a, thus hiding from View the screws which secure the strap 22 and the entire device to the outlet-box.

From the foregoing it will be seen that I have provided a simple, inexpensive, rosette type lighting fixture, having a one-piece disk and boss or hub in which the connection between the disk and the lamp receptacle socket is hidden from view and which will not tend to come apart, the said disk and hub also being of a uniform color and presenting a pleasing appearance to the eye. It will further be seen that the outer surface of the boss is so formed as to provide anchoring means for any suitable lamp shade supporting means.

Likewise it will be noted that in some instances the fixture securing screws may be hidden from View, thus enhancing the entire appearance of the fixture.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:

In a lighting fixture, a disc constituting a body and having a concaved inner face bordered by a flat marginal edge, an outwardly projecting neck at the center of said body formed with a bore extending through the body and having its walls threaded from its inner .end, ribs upon the inner face of said body extending radially of the body flush with the marginal edge thereof and terminating in spaced relation to the bore of the neck and having concaved inner end faces confronting the bore in spaced relation thereto, openings being formed through the body and the ribs to receive fasteners for securing the body against an outlet box, and an electric lamp receiving receptacle having a base and a threaded lampreceiving shell extending from the base and screwed into the bore of said neck from the inner end thereof and removably mounting the receptacle base against the central portion of the inner face of the body between and in close proximity to the concaved inner ends of said ribs.
