JAMES I. POLLAK, OF CHICAGO, ILLINOIS, ASSIGNOR TO U. S. TOOL MANUFACTURING COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

SHADE HOLDER.

Application filed. February 10, 1923. Serial No. 618,338.

To all whom it may concern:

Be it known that I, JAMES I. POLLAK, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Shade Holders; 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 improvements in shade holders, especially'for electric light sockets or the like, and has for its particular object the provision of a shade holder which can be readily applied to the common electric socket now on the market, and which, when applied, will securely hold in desired position the shade with which the light-is equipped. Y

One of the important objects of this invention is the provision of a shade holder for electric light sockets or the like, which can be readily detached therefrom so as to allow of the removal of the shade from the light or socket with a minimum expenditure of time and trouble, and which is so constructed that the shade can be readily and conveniently replaced when desired A further important object of this invention is the provision of a shade holder for electric lights or the like which ismade in practically one piece, and which comprises an integral spring hinge element whereby the eflicient operation of the same is insured at all times.

Another and'further important object of this invention is the provision of a shade holder for electric lights or the like which shall be simple of construction, economical to manufacture, and composed of a minimum of parts so that it will not be liable to breakage, and can be easily operated.

. Other and further important objects of the invention will be apparent from the disclosures in the accompanyingdrawings and following specification.

The invention, in a preferred form, is

illustrated in the drawings and hereinafter and comprlses malnly a plate26 of suitable more fully described In the drawings;

Figurel is a bottom plan view of they improved shade holder of this invention.

F g re 2 is a id elevation of th sam Figure 3 is a front elevation of the device, showing the latching means.

As shown in the drawings:

The, reference numeral 10 indicates a circular plate forming the body of the shade holder, and provided with a downwardly extending annular flange 12; Holes 14: are provided in the plate 10 for purposes of ventilation, or for the more ready escape of heated air from around the main holder. The central portion of the plate 10 is cut. away to provide a circular opening for the reception of the light socket, and the edges of this opening are bent upwardly, thereby forming an upwardly extending annular flange or collar 16, which fits closely to the light socket when the device is in closed position.

As illustrated in the drawings, the circular plate 10 is provided with a diametrically extending cut or slit, as shown at 18, which practically divides the same into two equal parts; The slit 18 extends upwardly through the collar 16, as best shown in Figure 3, and divides the same into halves to correspond with the halves of the plate 10.

The cut 18 extends through the forward portion of the downwardly extending flange or skirt portion 12, as shown at 20 in Figure 3, but the skirt or flange 12 is continuous at a point diametrically opposite the cut 20, as shown at 22 in Figure 1, thereby providing a hinge to allow of a slightopening of the shade holder. As the metal of which the device is composed is preferably resilient, a spring-like hinge is thereby formed, which is integral with the material of the holder itself.

As'best shown in Figure 1 of the drawings, the slit or cut 18 is curved away adjacent both sides of the spring hinge portion 22 of the flange 12, as illustrated at 24, in order to provide for a better opening ofthe plate 10 at this point, and also to insure a good spring action of the connecting element at 22.

A spring action locking means is providedon the front portion of the shade holder adjacent the slit 20 in the flange 12,

spring-leaf element, as shownin Figure 3, which tongue 30 is so made as to pass underneath a struck-up portion of th skirt member 12, as indicated at 32.. A slight pro? tuberance 34' or the like is provided on .the

tongue or latch member 30 so as to com prise a latching means whereby the shade holder proper may be, locked into normal shade retaining position'a nd automatically maintained in such position by means ofthe (Jo-operation of the protuberance. 34 with the forward edgeof the struck up'la tching means .32. The bentloyer.endfl3l of the tongue 30 further providesaretaining means wherebyfi any accidental: excessive pulling apart ofthe two halves ofthe'plate 10 will be prevented .All undue str faiii sfon thespring hinge member 22 are therefore avoided. V It will be evident that merely depressing the latch member 30 by means. of the linger will suflice to make the protuberance 34 pass under the, struck np portion 32 and release the spring means.

-The downwardly extending annular flange or skirt l2is provided with slots 38, and in these slots are inwardly struck in tegral retainingstrips 40, which serve to co-operate with the circular lip of the shade holder, and retain the same in positionwhen the deviceis in locked relation with the lamp socket.

From the drawing, especially; F igure 1,

y it will be .noted that the strips 40 are formed with a projecting bend 42' at each end, which preferably extends slightly beyond the circumference of the skirt 12, thereby providing a greater resiliency in the strips, and permitting of slight adjustments when same become necessary, onaccount of the use of the device with different shade holders,'which may vary slightly 1ns1ze. v It will be seen that herein is provided a shade holder which canbe very economically manufactured, in that it is comprised of practically one piece, which can be'made in a single stamping operation, which op'eration will also serve to punch etite necessary ventilating holes l and also to cut the slits l8 and, 20.. The inwardly struck shade supporting members L0. can then be formed in another operation, which operation may also. comprise the punching up of the latch locking member .32. The latch means 26, .30, .31 can then be applied by means of the rivet 28, and the device is completed. c

.lt will be further evidentl that thesimplicity of this device will fec oinmeiitl' itj for universal use, a shth e ..shade holders now on the .market all comprise; a' M 7 much; greater number .ofapart's: elements ,wlrich' are rather difliciilt or operation, as for e'zi'arnple,

mon .in such holders, and which, when lost, render the shade holder practically useless. The close fit between the locking tongue 30 and the outwardly struck latching means 32 will provide a holder which cannot sag or become warped in operation, and thereby prevents any accidental dropping of the shade.

I am aware that many changes may be made, and numerous details of construction varied throughout a wide range without departing from ,the principles of this inven; tion, and I, therefore, do not purpose limiting the patent granted hereon otherwise than asnecessitated by the prior art.
