FIXTURE SUPPORT Filed Oct. 20, 1928 Patented June 17, 1930 GEORGE ARRAS, OF CHICAGO, ILLINOIS l FIXTURE SUPPORT Application filed October 20, 1928. Serial No. 313,704.

This invention relates in general to a ixture support and has more particular reference to a globe and shade fastener for electric fixtures, although it may have a more general application wherever applicable. f

@ne of the principal objects or" the invention is to provide means for attaching a shade or globe to a ysupport in a simple eli'ective manner. A further object of the invention is the provision of means for positioning a shade or globe in a given direc'- tion or location by the act'of fastening it in place.

Further objects of the invention will appear hereinafter, the drawing illustrating a preferred` embodiment of the invention.

In the drawing:

Figure 1 is a side elevation of a fixture support and a reflector in accordance with the invention;

Figure 2 is a sectional view of the fixture parts shown in Figure 1;y

Figure 3 is a view of the attachment end of aglobe or shade; and

Figure l is a sectional view'taken on the line 1 4 of Figure 2.

This invention provides a simple means for attaching 'a shade or lglobe to a fitting at the end of a conduit or to the lid of a conduit box by providing an electric lamp socket which is inserted through an opening in the base of the shade, and these parts then relatively rotated and the socket attached to its support which clamps the shade between the socket and its support.

In practice the socket is usually attached loosely to the support by fastening screws or the like, the shade or globe is inserted over the socket and rotated substantially ninety degrees and the socket then secured tightly in place, thereby clamping the shade in its intended place at the same time.

Referring more particularly to the drawing, a socket 5 for receivinP an electric lamp 6 has opposite projections the central portions of which are recessed on opposite sides and provided with a perforation 8 for receiving a fastening screw 9. At the side opposite the head of the screw is a washer 10 for holding it in seated in the recess at one end of the pro- Jeetion.

This socket is attached by means of the screws 9 to any suitable support, such for example ais a supporting head 1 1 threaded onto the end of a conduit 12 through which extend electric wires 18 for the socket.

AThis head l1 may be circular in form, as

shown in Figures 1 and 2 or the conduit outlet may be at one side of a fitting 11a for receiving a conduit 12a at right angles to the circular end, as shown in dotted outline in Figure 1, and the circular end of either form is usually provided withan overhanging flange 14 for receiving the end of a globe or shade. K

A shade or globe of any size or shape may be applied to the iixtureas for example an angle reflector 15, as shown in Figure 1, but the attachment shell 16 is reduced at its end to lit within the circular flange lll, and the end or bottom of this reduced portion has a shaped Opening 17 adaptedr to fit more orlless loosely over the socket 5 lso that the socket maybe passed through the opening vin the end of the shade. At opposite sides of the opening 17 are notches or extensions 18 having one radial portion and a curved portion extending from the outer end of the radial .portion such that the screws 9 of the socket are located in the notches 18 in contact with the radial portions thereof when the socket and shade are relatively rotated approximately a quarter turn or ninety degrees, bringing the remaining portions or loops 19 of the end of the shade between the socket and the'support to which it is attached, and when the screws are tightened securely clamping the shade between the socket and the support 11, and holding the shade in this position until the screws are released. 4,

This construction is particularly valuable in locating Aor positioning a number of shades or reflectors so that they will extend and remain in a certain direction. For example, a number of angle reflectors such as shown in Figure 1 are to be directed toward a bill board. It is necessary only place, the head being to set the lamp sockets in the proper direction at the ends of the conduits by means of the threaded connections between the parts and then when the shade or reflector is applied, it is inserted over the socket at ninety degrees to the position desired, rotated to the proper position, and fastened in place by the socket screws.

This invention may be applied in a great variety of ways to fixtures of various kinds and has particular application to globes and shades for electrical fixtures. The term shade is intended to cover reflectors, globes, plates and canopies.

I claim:

1. The combination with a fixture support; of a socket having fastening means to secure it to the support; and a shade having an opening in its base insertable over the socket, and rotatable to directly engage the base between the socket and its support.

2. The combination with a support, of a socket having fastening means to attach it to the support, and a shade having a corresponding perforation in its base through which the socket will pass when they register, and having portions engaged between the socket and the support when the shade is rotated, the fastening means being adapted to secure the shade directly therebetween.

3. The combination with a support, of a socket having side extensions with fastening means therethrough for attaching it to the support, anda shade having a perforation in its base to admit the socket therethrough and rotatable to directly and positively engage portions of the base between the side extensions and the support, the fastening means securing the shade in place.

4. The combination with a support, of a member having opposite projections with fastening means inserted therethrough for attaching it to the support, and a -shade having a perforated base to admit the member therethrough and with a notch in the perforation to engage the fastening means when the shade is applied between the member artid the support to o 5. The combination of a lamp socket, and a shade therefor, the socket having side project-ions with fastening means extending therethrough, and the shade having an opening to admit the socket and its projections therethrough, the opening having a projection to engage one of the fastening means when the shade is applied over the socket and rotated, to limit the rotation thereof.

6. The combination with a lamp socket having side projections with fastening screws inserted therethrough, of a shade having a base with a perforation through which the socket and its projections will pass closely, sides `of the perforation to engage the screws limit the rotation therethe base having notches at the and limit the relative rotation of the shade and socket when the shade is applied there- 7 The combination with a support, of a lamp shade adapted to be set in a predetermined angular position with respect thereto, and a lamp socket having fastening means for attaching it to the support, the shade having an opening tovclosely admit the socket therethrough and thereupon rotatable to engage the base at the edge of the opening between the socket and its support before the socket is secured thereto, the edge of the opening being formed with a notch to engage the fastening means when the shade is rotated to limit lthis relative movement and to position the shade at the predetermined angular position with respect to the support.

8. In a fixture support, a lamp socket having side projections with fastening screws therethrough, and a shade having a perforation through which the socket andits projections pass closely, the shade having notches at the sides adapted to engage the screws when applied to the socket and to limit the relative rotary movement of the shade and socket to ninety degrees.

9. A fixture support comprising aL shade having an opening through which a socket is adapted to extend, the edges of the opening being clamped directly between a socket and its support, and the opening having sidev notches which engage a socket fastening means to limit the rotation thereof.

10. A fixture support comprising a shade having a base opening which closely admits chosen Assas.
