in globe mounting means.

The object of my invention is to provide a novel construction which will permit the use of noncritical materials and still attain a rugged, easily adjustable, securely-locking, connector to hold in place removable globes or shades; to pro- 'vide a globesupport having a ceiling escutcheon Pursuant to Rev. st. Sec. 4888 I shall describe vized-and are of uniform sizes.

I 2 claims. (01. 2 40 -128) My invention'relates to improvements tions I I on such fixtures are generally standard- My invention concerns itself with the means for securing this neck portion and its attached globe It! to the ceiling ring.

The ceiling ring bezel may :be of any configuration depending upon the artists choice. Its function is to shield or cover-theusual metal conduit fixture box set in the ceiling to receive the electric outlet elements. At this point the plaster is usually broken and raw edges of lathing and illustrate in the drawing one embodiment of my invention. This is done with the intention that my invention shall not be limited to this form except as required by the state of the art and the claims appended hereto.

In the drawing:

Fig. l is a view in perspective looking down on the top of a ceiling-type mounting device which is removed from the ceiling and" is par- Fig. 4 is a view in cross-section taken on a vertical lane across the center of Fig. 1.

My invention is especially applicable to those installations where simplicity is desiredand the use of moulded or cast members made from glass, plastics, powdered metals, etc. i preferred. This is particularly true at the present tim due to critical shortages in the materials from which these devices have in the past been stamped or .tially cut away to show the single movable elespun. After the war when moulding and castings from magnesium alloys and other materials are available for civilian goods my invention will;

also find ready application.

The globe or fixture I0 is usually made of glass and covers a light bulb (not shown). It may be of any shape laid out by the artist but as shown in Fig. 4, regardless of the shape below the neck ring H, the latter i provided with the and plaster are exposed to View. The diameter of the bezel 20 is such' 'as to embrace or cover all of these unsightly elements of the building struc- 1 ture and thus provide an artistic escutcheon or ceiling ring. As shown in Figs. 1 and 4, the ceiling ring 20, used in describing my invention, has the vertical flange 2|, the substantially fiat Portion 22, and the depending ring portion 23 with a suitable decorative bead at 24 and 25. These decorative beads are not essential. When present they add strength and finish to the design. Mounted inside the ring 23 are the lug 26 and 21 which extend radially inwardly from, the ring 23 and are located to one side of a'diameter of the ring. As illustrated in Fig. 1, they are about apart. The reason for this is to permit insertion within the ring 23 of the annular collar H on the globe [0 so that its top edge M can be insertedabove the. lugs 26 and 2'! so the latter will project into the annular recess l2 and support the globe at two points. While I have shown twoof these lugs 26 and 21 they might be combined into one or there might be several." An'opening 30 is formed in the ring 23 generally opposite th location of the lugs 26 and 21. This opening maybe square, rectangular, or any shape so long as it is adapted to receive within it a resilient movable retractable lug 4|]. The latter has legs 4| and 42, which, when seen in cross-section, preferably should conform in shape to the inside edges 3| and 32 of the opening 30. If the legs 4| and 42 are curved in crosssection then it is better to have the side edges 3| and 32 of the opening 30'general1y conform thereto in shape. The retractable 'lug 40 has a lug portion 43 to engage in the concave annular recess. 12 of the globe Ill and it has the leg portions and 42' with indentations 43, 44, and

45 in each, adapted to latch against the side Y edges 3! and 32 of the opening 30.

erablyhas a top portion 46 adapted to engage the substantially flat under portion 22 of the ceilingv depressed annular groove l2. These neck porto ring 20 whereby the lug portion 43 is supported against any excessive downward tilting which might be imparted to it by the weight of the globe l8 pivoting around the fixed lugs 26 and 21. While I have shown three indentations 43, 44, 45 in each leg of the retractable lug there may be more or fewer. Likewise the exact shape of this retract- -ab1e member may be varied. It is preferable that it be made of a resilient material such as spring steel, if available, or it may be made of resilient plastics. While I have shown only one opening 30, some designers may wish to have more than one and use in each a retractable lug. This is optional.

The ceiling ring 20 is secured to the ceiling or to the metal conduit box (not shown) by means of the usual screws. A

In operation, assuming that the ceiling ring 20 has been secured in position, the globe I0 is tilted to one side so that its neck ring ll enters the ring 23 and then when the neck ring ii is moved L into a horizontal position its annular groove l2 opening 30 so that these edges will fall into anindentation 44 or 43 on each leg. Thus I have provided a structure which can be made from noncritical materials, which has a minimum of moving parts, and which lends itself to easy manufacture.

What I claim is:

1. In a ceiling fixture the combination of a ceiling ring with a downwardly extending bezel portion secured adjacent and below a substantially flat portion, one or more lugs extending inwardly from said bezel portion and located on one side thereof, an opening in said bezel portion in the region opposite to said lugs; a movable retractable lug fitted in said opening, having a lug portion to engage in the concave recess of a fixture fitted in said ring, side portions to engage the walls of said opening to hold it therein, and a top portion to engage said substantially fiat portion of said ceiling ring whereby the lug portion is supported against excessive downward tilting.

2. In a ceiling fixture the combination of a ceiling ring with a downwardly extending bezel portion secured adjacent and below a substantially flat portion, one or more lugs extending inwardly from said bezel portion and located on one side thereof, an opening in said bezel portion in the region opposite to said lugs; a movable retractable lug fitted in said opening, comprising a lug portion, indented side portions adapted to engage the walls of said opening and an extension thereon which extends into contact with the fiat portion of said ceiling ring whereby the lug portion is supported against excessive downward tilting.

SYLVESTER. A. BAKER.
