v E. L. WHITE. RESILIENT ATTACHMENT FOR SHADE HOLDERS.

APPLICATION FILED JAN.26. I916.

Patented July 18, 1916.

EDWIN L. WHITE, OF NEW YORK, N. Y., ASSIGNOR'TO J'. H. \VHITE MANUFACTURING COMPANY, OF BROOKLYN, NEW YORK, A CORPORATION OF NEW YORK.

RESILIENT ATTACHMENT FOR SHADE-HOLDERS.

Specification of Letters Patent.

Patented July 18, 1916.

Application filed January 26, 1916. Serial No. 74,292.

To all whom it may concern: Be it known that I, EDWIN L. WHITE, a citizen of the United States, residing at the borough of Brooklyn, county of Kings, city and State of New York, have invented an Improvement in Resilient Attachment for Shade-Holders, of which the following is a specification.

My invention relates to an attachment for shade holders employed on lamps and other lighting fixtures, and its object is to lessen the liability of injury to the glass or porcelain shade, whichv is usually clamped by metallic screws, the ends of which bear directly upon the glassware.

My invention consists of a member adapted for attachment to the end of a screw, said member being provided with a projecting spring, or spring arms, or a pad gripped by said arms to contact with the shade or globe, thereby giving a soft or yielding pressure against the glassware and preventing the metal of the screw coming into contact there with.

In the accompanying drawings, Figure 1 is an elevation of the preferred form of my invention. Fig. 2 is a rear view of the same. Fig. 3 is an elevation of a modified form of the invention. Fig. 4 is a rear View of the same. Fig. 5 is an elevation of another modification. Fig. 6 is a rear view of the same. Fig. 7 is a view showing my invention applied to a hanger and shade such as are employed on semi-indirect lighting fixtures. Fig. 8 is a view of the invention applied to a shade ring such as used upon lamps and gas fixtures. Fig. 9 is an elevation of the device where the disk and arms are made of separate pieces and secured together, and Fig. 10 is a rear view of the same. Figs. 1, 2, 3, 4, 5, 6, 9, and 10 are in enlarged size for clearness of illustration.

Similar reference numerals indicate like parts throughout the several views.

In the preferred form of my invention, 10 indicates a disk or piece of metal or other suitable material having a screw-threaded central opening 11 and spaced arms 12, at right angles to the disk. The free ends of these arms are preferably pointed.

The disk 10 with its central opening and arms 12 is preferably cut out of a single fiat niece of metal and the arms bent up at right angles; but the disk may be a separate piece of any desired thickness with the arms attached in any suitable manner. p 1

13 indicates a pad of felt or other fibrous or spongy material which is inserted between the arms 12, after which the pointed ends of the arms are pressed against or into said pad to hold the same in position upon the disk 10.

In the modified form shown in Fig. 8, instead of employing the pad 13, the disk 10 may be made smaller in diameter, and the arms 12 of greater length with their free ends curved slightly outwardly to bear against the glassware; there being sufficient spring in the arms to prevent undue pressure upon the shade, and to yield sufiiciently upon expansion of the glassware to prevent injury thereto.

In Fig. 5, I have illustrated another modification by which the pad 13 may be dispensed with. In this form, a volute spring 14: ex tends from the disk 10, to bear against the shade. i

In either modification the device may be cut out of a single flat piece of metal and bent to shape. In the last named modification, I prefer to punch the opening 11 in the disk and cut or press a screw-thread therein, so as to provide an increased bearing upon the screw 15, where the device is cut out of a comparatively thin piece of metal. It will read ily be seen thatthe opening in the disk may be similarly formed in either instance, if desired where the disk and armsare formed of one piece of sheet metal.

In Fig. 7 of the drawing, I have illustrated my invention applied to a hanger 16, and globe 17 such as are employed in semi-indirect lighting fixtures, and in Fig. 8 I have shown itapplied to a shade ring 18, such as used upon lamps and gas fixtures.

It is of course applicable whether the burner and shade are upright or inverted.

It will be understood that other modifications may be made without departing from the spirit of my invention, which provides a resilient member adapted for attachment to the end of a screw and to contact with the 1. A device of the character described,-

comprising a disk having a screw threaded shade.

3. In a lighting fixture, the combination of a shade, a support for the same, a screw passing through an opening in said support, a disk provided with an opening to receive the end of said screw and connect it with the disk, arms projecting from said disk, and a pad gripped by said arms and contacting with said shade.

Signed by me this 11th day of January,

EDWIN L. WHITE.
