LIGHTING rrxruan.

Application filed January 24, 1927. Serial No. 163,037. I

My invention relates to lighting fixtures, and more particularly to an improved and simple device for supporting a lamp socket, an indirect reflector or ceiling or wall piece and a globe or other lamp shade, said device being readily detachable and interlocking the parts together in a practical and convenient manner. I

In order to explain my invention more fully, I have shown one practical embodiment thereof on the accompanying sheet of drawings, which I will now describe.

Figure 1 is a view, partly in elevation and partly in section, showing a ceiling fixture embodying my invention;

Figure 2 is a plan view of a member to be secured against the ceiling or wall;

. Figure 3 is a sectional view through Fig.

2, on line 3-3;

Figure 4 is an inside plan view of the holding member which is detachably secured to the member seen in Fig. 2, and which holds the other parts making up the fixture; and

Figure 5 is a fragmentary sectional view taken on line 55 of Fig. 4.

In lighting fixtures which are to be secured against aeeiling, or against a wall, it is quite common to provide two portions, one to be secured against the ceiling, or against the wall, either for ornamental or indirect lighting purposes, and the other portion to surround a lamp or to constitute a shade or direct reflector. These portions are usually made of porcelain or other translucent pottery, plain or decorated. It is the object of my invention to provide a very simple, practical and convenient means for securing these two portions together against the ceiling or the wall and in such a way that they can be detached-and removed for any purpose with a minimum of effort and with the fewest possible detachments.

Referring now more in detail to the drawings, I have shown one practical embodiment of my invention in a fixture secured to a ceiling, the two portions-being designated, 6 and 7 respectively. The part which is permanently secured to the ceiling is shown here as a ring member, 8, secured by means of two screws, 9, 9, screwed into the ceiling, C, with two screws, 10, 10, screwed into an inner flange portion, 11, of said ring, said screws, 10, 10, having heads and being adjustable in said ring member 8. This ring member 8, is known in the art and is used as a permanent supporting means and is, therefore, one of the known or old elements used in my new combination. The main feature of my invention is a detachable cup-like member, designated as a whole, 12, shown in Fig. 4, and also in place in Fig. 1, having in its bottom, in the present showing, two pairs of bayonet holes, 13, 13, and 14, 14, the holes being differently spaced for-differently spaced screws, 10, 10. The pair of holes 13, 13, fitting one spacing, while the holes, 14, 14, would fit another spacing of said supporting screws, 10, 10, in the permanent ceiling or wall ring, 8, as will be clear from the drawings.

Said cup-like member, 12, also has a central opening in its bottom or top, which opening is designated 15, to receive the usual lamp socket, designated, 16, and shown in Fig. 1, and clamped to said member 12, through said central opening, 15. Said cuplike member 12, also has struck out of its side, two inturned lips, as 17, 17, shown clearly in Figs. 4 and 5, and at the opposite side thereof is provided with a small thumb screw, as 18. ,These two instruck lips, 17 17, and said thumb screw, 18, constitute means for holding the shade portion, 7, in place, as will be clear from Fig. 1. Said cup-like portion has its lower edge turned outwardly to form a supporting flange, 19, which fits around the lower edge of the shade portion, 6, and supports it against the ceiling when said cup-like member, 12, is placed therethrough before being attached to the supporting screws, 10, 10, in the ring member 8, in the manner before described.

Thus to assemble the parts together and secure them in place against a ceiling, or wall. the lamp socket, 16, is secured to the member, 12, said member 12, is then inserted through the shade portion, 6, in the position indicated in Fig. 1, and the parts thus assembled are placed against the ceiling, over the ring. 8, with the heads of the screws, 10, 10, in the bayonet holes, 13, 13, and when slightly turned, said member 12 and said shade portion, 6, are secured in place firmly against the ceiling. The other shade portion, 7 is then inserted with its flange portion, 7 above the two lips, 17, 17, and with the thumb screw. 18, said lower shade portion, 7, is secured in place. It is only necessary to loosen the screw, 18, to remove the lower portion, which, of course, is not new, but the combination with a simple member,

12, which makes itpossible *to interlock two shade portions together, and to secure them quickly and firmly to the permanent ring member, 8, or its equivalent, with the upper portion 6, of the shade held in place, so far as I am aware is new and patenta ble.

I do not limit my invention to the showing made for descriptive purposes except as "I may be limited by the hereto appended claims. t i i I claim: t

t In a fixture-of the character shown and described, wall member of annular form to be secured against a wall with screws at opposite sides adjust-able therein with their heads outwardly, a cup-like member having abottom with open center and bayonet holes therethrough at opposite sides to'receive said screw head-s and having its side flange outwardly fiarediat its loweredge, a lamp socket member mountedin the open center of said cup-likc member and in said annularwall member, a wall shade member over said cup-like member against the wall and having a portion fitting around the outside of said cup-like member with its lower openingsubstantiallyin register with the mouth i said shade of said cup-like member, and a shade, 'memher having its upper end adapted to fit Within sairlcup-like member, and means for su porting sa dshade member in sald cup-l1 e member.

2. f-In a fixture of the character referred to, in combination, an annular ring to be securedia ainst a wall a cu -like*inember mouth over said cup-like member, and a 4 shade member havlng its mouth inserted into the mouth of said cup-like member, and means holding saidcup-like member and members in inter-fitting relationship,
