ATTORNEY Patented June 17, 1930 UNITED STATES PATENT OFFICE LEROY C. DOANE, OF MERIDEN, CONNECTICUT, ASSIGNOR TO THE MILLER COMPANY, 01 MERIDEN, CONNECTICUT, A CORPORATION OF CONNECTICUT LIGHTING FIXTURE Application filed March 9, 1927. Serial No. 173,831.

The present invention relates to lighting fixtures and is more particularly directed to the type of lighting fixture or lighting unit having a single centrally located electric lamp carried in a downwardly opening lamp socket.

One of the objects of the present invention is the provision of improved attaching devices for supporting the lamp socket from the loop customarily used in such lighting units.

Another object of the invention is to provide an improved frame for supporting the opaque deflector and difiusing disk of semiindirect lighting units. These improvements relate more especially to a frame for this purpose which may be easily assembled when installing the fixture and which supports the deflector when the glass diffuser is removed, and to the means for releasably supporting the diffuser.

A further object of the invention is to provide improved means for supporting the -structional parts of the lighting unit so that no strain is brought on the lamp socket.

Other and further objects of the invention will be apparent as the description proceeds.

The accompanying drawings show, for purposes of illustrating the invention, one of the many possible embodiments in which the invention may take form, it being understood that the drawings are illustrative of the invention rather than limiting the same.

In these drawings:

Figure 1 is an elevational view with parts in section showing a lighting fixture embodying the present invention;

Figure 2 is an enlarged view illustrating the upper part of the lighting unit;

Figure 3 is a fragmentary view of the socket housing and locking ring employed in the upper part of the unit;

Figure 4 is a top plan view of the ring at the lower part of the unit for supporting the deflector and difiuser;

Figure 5 is a perspective view of one of the straps which supports the ring of Figure 4;

Figure 6 is a fragmentary view illustrating the assembly of the frame; and

Figure 7 is an elevational view illustrating the removal of the lower glass diffuser.

As here shown, the lighting unit is of the pendant type and is carried at the lower end of a chain 10 by means of a suspension element such as a loop 11. As shown in Figures 1 and 2, this loop has a skirt 12 internally threaded as indicated at 13 and exter- An inverted cup-shaped sheet metal stamping 22 is provided with a hole to fit against the reduced lower end 15 of the loop so that the stamping 22 may be fastened onto the end of the loop bybeing interposed between the disk 18 and the loop 12. For convenience the upper end of this stamping 22 has holes punched in it to permit the screws 20 to pass through. The stamping 22 functions as a housing or cover for the socket and as a supporting element for other parts of the fixture to be described. An outer ornamental cover 23 is mounted on the loop as indicated and is held in the lower position by a nut 24 threaded onto the outside of the loop. When it is desired to raise the outer ornamental cover 23, the nut is released and the parts lifted up above the loop to give access to the lower part of the inner socket cover or housll'l lhe lower end of the socket cover or hou ing 22 is provided with vertical recesses 2h preferably three in number, and extend a short distance upwardly to holes 26 punched in the side of the socket cover or housing. A number of depending straps 27 are provided with inwardly bent upper ends 28. These inwardly bent ends are adapted to pass through the holes 26 in the socket cover and the upper portion of I the straps 27 are adapted to lie in the recesses 25. To look these straps in place, a locking collar 29 is provided. This collar is preferably held on ferred to.

the socket cover by a rivet or pin which asses through a Z-shaped slot 31 in the colar. When the collar is in the upper position as indicated in Figures 2 and 6, the straps may be inserted in place and when the collar is lowered along the slot 31 and given a slight turn, it is impossible for the straps to become loosened from the socket cover or housing. In order to provide a'convenient grip for the collar 29 and that the outer ornamental socket cover may be held securely in position, a flange 32 is provided at the upper end of the collar which engages the inner wall of the socket cover 23.

The straps 27 form the sole support for the deflector 33 and glass di'fl'user 34 above re- The straps 27 are adapted to pass down along the neck 35 of a lamp bulb 36 and are then bent outwardly and twlsted as indicated at 37. Below the twisted ortion of the straps, they extend vertically ownward, as here indicated at 38, and the straps are then bent as indicated to form a horizontal portion 39, a vertical portion 40 and an outwardly directed foot 41. A rin 42 shown more in detail in Figure 4 is provlded with a number of outwardly directed lugs or proj ections 43 having holes 44 adj acentthe outer wall 45 of the ring. The lower. inner edge 46 of the deflector is outside of the straps 27 and rests on the lugs 43. Hooks 47 are pivotally mounted on the lower side lugs 43. These hooks may be made out of a piece of twisted strap as indicated and held on a pin 48 passing through two ears 49 as indicated. These hooks are just the proper size and shape to engage the periphery 50 of the glass diifusing disk 34 and hold it in position. In assembling the fixture, the socket is wired in and mounted in the socket cover as previously described and the unit may be hung from the ceiling and connected with thehouse wires. The feet 41 of the straps 27 are passed through holes 44 in the ring 42 and these straps are then swung inwardly as indicated at the right of Figure 6 to bring the inwardly bent upper ends 28 into the slots or holes 26 in the socket cover. After this the collar 31 is moved down to lock the frame together. The portions 39 and 40 of the straps securely embrace the ring 42. The socket cover, straps and rin form a subs-tantial rigid self-supporting not collapse until it is disassembled. After the frarre has been assembled the deflector 33 may be tipped sidewise and passed upwardly over the ring in an obvious manner and then brought to rest on the lugs 43. The lam 36 may be inserted in the socket and the di using disk caught in to two of the hooks 47 p as indicated in Figure 7 and then the third hook snap ed into position as shown in Figure 1. The xture may be disassembled by reversing the order of the above operations.

It will be noted that this frame can be asf rame which will sembled and disassembled without the use of any toolswhatever. It will also be noted that the present form of construction'provides a rigid support for the deflector and makes it unnecessary to lower these deflectors when making lamp renewals or for cleaning the fixture. The ability to support the deflector on a non-collapsin frame is particularly important in larger xtures of this type which are sometimes provided with heavy ornament such as a ring indicated at 33.

It is obvious that the invention may be embodied in many forms and constructions within'the scope of the claims, and I wish it to be understood that the particular form shown is but one of the rgany forms. Various modifications and changes being possible, I do not otherwise limit myself in any way with respect thereto.
