Specification of Letters Patent.

Patented Mar. 3, 1914.

To all whom it may concern Be it known that I, F REDERIOK W. Wann- FIELD, a citizen of the United States, and a resident of Vermilion, county of Erie, and State of Ohio, have invented a new and useful Improvement in Combined Receptaole-Covers and Shade-Holders, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

The subject of the present invention is a combined receptacle, cover, and shade holder for electric lighting fixtures, and is designed to provide a means for not only covering and protecting the lamp receptacle or socket of an electrical fixture, but also a shade holder which may be easily and simply attached to the cover or the receptacle.

To the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed drawings and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of the various mechanical forms in which the principle of the invention may be used.

In said annexed drawin 's:-Figure 1 is a side elevation of the penc ant support extending from the ceiling and the receptacle cover; Fig. 2 is a side elevation of the invention when all of the parts are assembled ready for use; Fig. 3 is a view similar to Fig. 1, except that the parts are here shown assembled and a shade and lamp are in place, while the yoke is shown from the side; Fig. 4 is a bottom plan view of Fig. 3; Fig. 5 is a section on the line 5-5, Fig. 1, showing the shade holder connected to the receptacle, and Fig. 6 is a central vertical section of several shade holders illustrating the manner in which the same may be attached to a single sized receptacle; and Fig. 7 is a central section through the shade holder.

lln Fig. 1, I show the pendant support 1 extending from the ceiling and connected to a saddle or yoke 2 provided with two out wardly extending arms 3 terminating in inwardly extending lugs l which are adapted to contact against the shoulders 5 of the receptacle 6 to which they are attached by means of screws 7. The lugs l are rounded at the lower edges thus spacing the corners from the shoulders 5 of the receptacle. A cover 8 for the saddle and receptacle is formed in cone-shape and is provided with an aperture at its upper end adapting it to be slipped over the support 1 and down into snug engagement with the saddle, as shown in Fig. 3. The cover 8 is provided with an inwardly extending bead 9 a short distance from its lower edge, which is adapted to resiliently slip between the edges of the lugs 4- and the shoulders 5 when the cover is compressed slightly into oblong form. The resiliency of the cover will tend to force it back into its normal shape as soon as the bead has engaged against the shoulders, thus providing for a snug and resilient engagement of the cover on the saddle. The position of the cover, and the shape it may he made to assume when disengaged, are shown in Fig. 5. lVhen engaged with the receptacle, the bottom of the cover is circular, as indicated by the full heavy lines in Fig. 5. By pressing on the cover at either side between the points of attachment to the shoulders 5, the cover is forced into the shape indicated by the dotted lines, when it may he slipped off the receptacle. The receptacle is, of course, internally threaded, adapting it to receive an electric lamp 10. The two screws 7 which attach the saddle to the receptacle are provided with enlarged heads and are not brought into contact with the lower sides of the shoulders.

A shade-holder 12 is formed annular and of a size slightly larger than the bottom edge of the cone-shaped cover. The shade holder 12 is provided with an inwardly extending flange 13 on its upper edge, such flange being depressed, thus adapting it to fit around the cover 8, as shown clearly in Fig. 3, and effecting a close fit between the cover and shade-holder. The flange 13 on the shade-holder is also provided with two slots 14, which consist of two connected apertures, one of such apertures being larger than the other thus forming the common bayonet joint. The two larger apertures are oppositely disposed on the flange and are adapted to fit over the heads 11 of the screws 7. The shade-holder is then rotated slightly thus bringing the smaller apertures into register with the screws 7, the latter apertures not being large enough to permit the shade-holder to slip over the heads of the screws. It is, of course, a simple matter to disengage the shade-holder by rotating the same in the opposite direction and then pulling vertically downward.

The shade holder is provided with a lateral circular shoulder 20 adapted to contact against the lower bent in edge of the cover 8 and to maintain the same in position.

A shade 15 may be held in the shadeholder in the manner indicated in Figs. 2 and 3 by means of small set screws 16. This engagement is the usual and quite common method of holding the shade in the shadeholder and is, of course, no part of the present invention.

In Fig. 6 it is shown that any desired size of shade-holder may be used with a single size cover so long as the depression in the flange is equal in size to the shoulders on the receptacle.

The simplicity of my improved cover and shade-holder will be evident. But two members are required to perform these functions, the cover and the shade-holder, and the two are so designed that they snugly engage when assembled and present a pleasing appearance to the eye as well as an efficient means for covering the receptacle and holding the shade.

It will be understood that the cover 8 may be given any desired conformation externally to suit the taste of the designer; also that the form of the shade-holder 12, whatever its size, may be similarly varied. The cover, when raised as in Fig. 1, allows of the connection of the wires, passing down in the support to the receptacle. The convenience of this construction will be readily seen.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the tollowing claims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as my invention 1. The combination with an electric lamp receptacle; of a cover adapted to resiliently and detachably engage the sides of said receptacle; and a shade holder detachably secured to said receptacle, thereby preventing disengagement of the latter.

2. The combination with an electric lamp receptacle; provided with a plurality of shoulders; of a flexible cover adapted to resiliently engage such shoulders on said receptacle; and a shade holder detachably secured to said receptacle, thereby preventing disengagement of the latter.

3. The combination with an electric lamp receptacle; provided with two oppositely disposed shoulders; of a flexible cover provided with an internally extending flange adapted to resiliently engage over suclr shoulders; and a shade holder detachably secured to said receptacle, thereby preventing disengagement of the latter.

a. The combination with an electric lamp receptacle, provided with two oppositely disposed laterally extending shoulders having engaging members on their lower faces; of a flexible hollow cover provided with an internally extending flange adapted to resiliently engage over such shoulders; and a shade-holder having apertures adapted to receive such engaging members on said receptacle.

5. The combination with a pendant sup port, of a yoke attached thereto, each arm of said yoke being provided with a lug; an electric lamp receptacle provided with two oppositely disposed laterally extending shoulders adapted to register with such lugs on said yoke; screws engaging such registering lugs and shoulders; a shade-holder detachably secured to said screws; and a flexible hollow cover provided with an internally extending bead adapted to resiliently engage such shoulders.

Signed by me, this 22d day of October, 1912.

FREDERICK W. WAKEFIELD.
