SHADE Herman FOR LIGHTING FIXTURES.

Application filed April 21,

prevent the unsightly appearances of the fastening means associated with the lamp shade,

One of the important objects of the present invention is to provide a lamp shade holder of the above mentioned character, which will permit a lamp shade to be easily and quickly removed from the fixture when ever necessary.

A further object of the invention is to provide a lamp shade holder of the above mentioned character, which will obviate the necessity of having to manually adjust the fastening means for engagen'ient with the lamp shade, means being associated with the clamping means for holding the same in engagement with the lampshade, thus preventing the accidental displacement of the lamp shade from the fixture.

A further object is to provide a lamp shade holder of the above mentioned character, which is simple in construction, inex pensive, strong and durable and furthermore adapted for the purposes for which it is designated.

Other objects and advantages of this invention will become apparent during the a course of the following description.

In the accompanying drawing forming a part of the specification and in which like numerals designate like parts throughout the same:

. Figure 1 is a side elevation of my improved device showing the same in use, parts being shown in section.

1224. Serial No. 707,948.

In the drawing wherein for the purpose of illustration is shown the preferred e1nbodiment of my invention, the numeral 1 designates the lamp socket of a lighting fixtrue 52, the lamp socket being externally threaded in the usual manner. .The lamp shade is designated by the numeral and thesame of the usual construction having the bead l provided on the upper edge thereof. Ordinarily the lamp shade has been supported on the lighting fixture b means of a collar mounted on the lighting fixture and the same having an annular flange in which are supported adjusting screws, the inner ends of which are adaptei'l to engage the upper portion of the lamp shade. This construction necessitated the loss of considerable time and labor in scour ing the lamp shadein position on the fix- .ture around the lamp and often times the lamp shade would not be properly positioned around the lamp due to thefact that certain of the screws would extend inwardly for a greater distance than the other screws. Further when the lamp shade is supported on the lighting fixture by means of the fastening screws, the latter usually are difficult to be removed from engagement with the shade when the shade has been on the fixture for a considerable length of time.

To enable a lamp shade to be securely supported on the lighting fixture in proper position and to further prevent the unsightly appearances caused by the fastening screws heretofore used, I provide a simple and cilicient means which may be readily placed in position on the lighting fixture and which will efficiently and rigidly support the lamp My improved lamp shade holder comprises a collar 5 which is threaded for engagement with the threaded lamp socket 1 and thecollar is provided with the annular flange 6 which extends outwardly from the lower portion of the collar in the manner clearly shown in Figure 1 of the drawing. The flange 6 has extending radially therefrom the arms 7, in the present instance three of such arms are shown. These arms are adapted to be arranged equidistant with respect to each other and the outer ends of the arms are bifurcated as shown at 7 and 8.

Adapted to be pivotally supported in the bifurcated ends 8 of the arms 7 are the upwardly extending project-ions 9 the same ex" tending upwardly from the spring elements 10. Each spring element comprises a fiat spring steel strip which is curved as shown at 11 and has its outer ends curved as shown at 12 and 13 respectively in the drawing. The purpose of this arrangement will hereinatter be more fully described. The upper ends of the projections 9 formed on the spring elements 10 are looped around the transversely extending pins 14 which extend through the bifurcated ends of the arms 7 whereby the spring elements may be pivotally supported between the bifurcated ends of the arms and adapted for swinging movement on the transversely extending pins l i. Cooperating with the springs 10 is the locking ring 15 the upper end of which is provided with annular flange 16.

In use, when it is desired to support and secure the lamp shade 3 on the lighting the ture Q, the collar is threaded on the lamp socket 1 and the locking ring 15 is moved u m'ardly out of engagement with the spring element. The lamp shade 3 is then placed around the lamp and within the spring element in such a manner as to have the outer curved portions 12 and 13 or each spring in engagement with the upper portion of the lamp shade 3 directly below the head at. The locking ring is then moved downwardly so that the ring 15'will engage the curved portions ll of the springs 10 and force the springs into engagement with the lamp shade so that the lamp shade will be securely supported around the lamp. It is to be understood that the flange 16 formed on the upper end of the locking ring 15 will rest on the upper ends of the projections S) of the springs so as to prevent the displacement of; the locking ring from engagement with the springs.

The lamp shade 3 will thus be centered properly around the lamp and will be supported on the lighting fixture in such a manner as to prevent the accidental displacement therefrom. Furthermore the fastenin means for the lamp shade is entirely covered by the locking ring 15 and thereby causes the lamp to be more attractive. The simplicity in which my device is constructed enables the same to be easily and quickly adjusted so that a lamp shade may be readily removed from the fixture whenever it is desired to clean the same or when the same has become broken and is to be replaced b a new one. A device of this character may also be manufactured at a very low cost and will be strong and durable.

lVhile l have shown the preferred embodiment of my invention, it is to be understood that yarious changes in the size, shape and arrangement of parts may be resorted to without departing from the spirit of the inrention and the scope of the appended ciann.

Having thus described my invention. what I claim is A lamp shade holder comprising a collar haying radially disposed spaced arms. T-

shapcd spring members having their intermediate portions pivoted to the M3113 and the end portions of the said spring members being concaved transversely, the concaved surfaces being disposed toward the center of the collar and a locking band adapted to engage around the spring members.

In testimony whereof I affix my signature.
