Patented Jan. 10, 1933 UNITED STATES PATENT ortica j CARL A. SCHROEDER, F VERMILION, OHIO, ASSIGNOItTO THE F. W. 'WAKEFIELD BRASS i COMPANY, OIF VERMILION, OHIO, .A GGRPORATION OF OI-IIG LIGHTING FIXTURE Application led September 18, 1931.

This application relates to' lighting lixtures, and more particularly those of acharacter for use in electric lighting; and it is among the objects of the invention to provide a fixture which is rugged and capable of safe-guarding the lighting elements in a secure manner, while at the same time being readily accessible for changes, repairs, etc. Another object is the provision of a regulable mounting allowing the use of shades of different weight and extent, etc. Other obj ects and advantages will appear as the description proceeds.

To the accomplishment of the foregoing and related ends, the invention, then, comprises the features hereinafter fully de scribed and particularly pointed out in the claims, the following description and the annexed drawing setting forth in detail certain illustrative embodiments of the invention, such being indicative however of but one of the ways in which the principle of the invention may be employed.

In said annexed drawing Fig. 1 is aside eleva-tional view of a fixture in accordance with the invention; Fig. 2 is an aXial section; and Figs. 3 and 4; are side elevational views of details. Y

Referring more particularly to the drawing, there is shown an anchor element 2 which may be of stamped sheet metal of suficiently heavy gauge, and which may be secured to a ceiling or support in any suitable manner, for instance by screws 3 connecting with a plate l which is secured to an'outlet stud or the like. Carried by the anchormember is a lamp socket 6, this preferably being of heavy duty porcelain-type and containing the usual-form threaded internal bushing 7 to receive the lamp. The socket may be attached to the anchor-member by convenient means, for instance screws 8. On the outer surface of the socket screw-threading is provided and preferably this may be in the form of a surrounding barrel 9, which may be held in assembly by the securing means 8. A collar 10 engageable with the aforesaid screw-threaded surface may then be set into position thereon as desired. Such screw-threads thus provide a surface upon Serial No. 563,547.

which a means for holding a canopy may be regulably positioned, and also a surface upon which'means for holding a shade may be regulably. positioned. Preferably, these two holding means may be combined into a com-V` mon means accomplishing both functions, and for instance a screw-threaded collar may be provided with portions respectively adapted therefor. Desirably, the collar 10 may carry at one end a flange 11, and at its other end extended outstanding projections 12 for engagement within a lamp shade 13. Thelatter may vary in form and contour, depending upon requirements in any particular instance, and by reasony of space limita tions is shown in the illustration partly broken away.

lThe canopy 14 and a shade cover 15 are arranged to coact, for instance by telescopic engagement, one element within the other. The particular arrangement may bev varied, but preferably the canopy 14; may have a cylindrical portion 16 upon which the shade cover may be slidably mounted. If desired, a bead or stop 17 may be provided in the cylindrical portion of the cover. lVith such arrangement, the shade cover 15 may be raised up out of the way in making changes or replacements, cleaning, etc.

By shaping the projections 12 to a relatively small eXtent of arc, with respect to the circumference of the neck of the shade `or globe to be supported, the latter may be easily inserted or removed when the collar is in place, by tilting the globe suliiciently to pass the neck thereof over the support 12` at o ne side, and then retilting and centering back to median final position.

lVhere it is desired to use open style shades, as contrasted with closed globes, the project-ions 12 may extend about a material part or the entire 380 corresponding tothe neck of the shade to besupported, and placement and removal of the shade can then be ,accomplished with the collar in the shade,

of the shade or globe and is then finally seated down into engagement with the shade in position.

Other modes of applying the principle of the invention may be employed, change being made as regards the details described, provided the means stated in any of the following claims, or the equivalent of such, be empkyed.

therefore particularly point out and distinctly claim as my invention 1. In a lighting fixture, an anchor member, a canopy for covering the same and having a depending cylindrical portion, a lamp socket carried by said anchor member, a screw-threaded barrel about said socket, a collar engageablc on said barrel and having an out-turned flange at its upper end and Vlaterally projecting shade supporting portions at its lower end, and a shade cover movable on the cylindrical portion of the canopy.

2. In a lighting fixture, an anchor member, a cano y for covering the same, a lamp socket carrie lby said anchor member, a screwthreaded barrel about said socket, a collar screw-threadedly engageable on said barrel and having an out-turned flange at its upper end and shade supporting projections at its lower end, and a shade-cover in telescopic relation with the canopy.

3. In a lighting fixture, an anchor member, a. canopy for covering the same, a lamp socket carried by said anchor member, screw-threads outside said socket, a collar engageable on said screw-threads for locking the canopy above and having shade supporting projections below, and a shade-cover cooperating with said shade-supporting projections.

4. In a lighting fixture, an anchor member, a canopy for covering the same, a lamp socket carried by said anchor member, screw-threads outside said socket, a collar engageable on said screw-threads and having shade-supporting projections, and a. shade cover about said collar.

5. In a lighting fixture, an anchor member, a canopy for covering the same, a lamp socket carried by said anchor member, screwthreads outside said socket, a collar engageable on said screw-threads for holding the canopy. and a shade cover about said collar.

6. In a lighting fixture, an anchor member. a cano y covering the same, a lamp socket carrie by said anchor member, screw threads Outside said socket, and means in common for supporting said canopy and a shade, said means including a screw-threaded member engageable on the aforementioned screwthreads, and having a canopy-supporting projection .and terminating in shade supportm extensions.

I. In a lighting fixture, an anchor member, a. canopy covering the same, a lamp socketcarried by said anchor member, a screwthreaded barrel about said socket, and means CARL A. SCHROEDER.
