To all whom it may concern: 7

Be it know-n that I, Or'ro H. Mona, a citizen of the United States, residing at. Oakland, county of Alameda, and State of Cali' fornia, have invented a certain new and useful Improvement in Frames for Lighting Fixtures, such as are described and shown in my United States Design Letters Patent #531,021, dated July 10,1917. In this patent the lighting unit is formed of a plurality of glass strips, whichare carried by a frame, the strips of glass being placed at an angle, so as to conceal the source of light. A good deal of difiiculty has been experienced in providing a suitable frame for holding these strips which could be quickly and easily assembled and which would hold the strips securely and without danger of breaking.

My invention has for its object to provide such a frame, and one which will not be expensive to manufacture. 7

My means of accomplishing the foregoing objects may be more readily understood by having reference to the accompanying drawings, in which:

Figure 1 is an inverted view of my improved frame, showing one of the strips of glass in place.

Figs. 2 and 3 are detail views of the various parts.

lar parts throughout the entire description.

As shown in the drawings, the frame consists of an annular member 6, which is provided with a plurality of recesses or slots 7, adapted to hold the lower end 8 of the glass strip 9. The inner part of this annular member 6, has a plurality of bosses 10, cast or formed thereon, which are threaded and have mounted therein upwardly and inwardly extending rods 11. A disk 12 is secured to the upper end of these rods by means of threaded holes into which the ends of the rods 11 are screwed. The disk 12 is provided with a plurality of notches 13, adapted to receive and hold the end 14 of the glass strip 9. A rod 15 extends up wardly from the central portion of the disk and has threads 16 cut thereon. A cushion 17, formed of felt or other suitable material is mounted upon the disk and is adapted to engage the end 14 of the glass strip 9.

A cover or cap 1.8, ismounted above the cushion 17, and is provided with a central opening 19, through which passes the rod 15.

The assembling of the device is accomplished as follows:

The frame is inverted as shown in the drawing. The large end 8 of the glass strip 9, is placed in the slot 7, formed in the annular member 6. Theupper end 14 is placed in the corresponding notch formed in the disk 12. The cushion is then placed on top of the disk so that it abuts against the end of the glass strips 9. The disk, cushion and ends of the glass are then coveredwith the cap 18, the rod 15 passing through the central opening 19 formed therein. The whole is then tightened into position by means of a lock nut 20, and a knob 21 is then screwed upon the threads 16 on the end of the rod 15, forming a suitable finish. The frame is then placed in position and is ready to be hung as a fixture with the light bulb inside of the conoidal portion, it being concealed by the plurality of glass strips 9.

Although I have shown a specific number of rodsand specific formsfor the various parts, it will be apparent to persons skilled in the art, that changes may be made'in the details of construction, without departing from the scope of my invention, and I do not desire to limit myself to the necessary details shown and described.

Having described my invention what I regard as new and desire to secure by Letters Patent is:

1. A frame for lighting units formed of strips of glass, comprising the combination of an annular member, having a plurality of slots formed therein, a disk having a plurality of notches in its periphery, corre-' sponding to the slots in the annular member, means to hold the two in spaced relationship, a cushion abutting against the ends of the glass adjacent the disk, a cap which fits over the cushion. and disk, and means to secure and hold said cap and thereby the glass in position.

2. A frame for lighting units formed of strips of glass, comprising the combination ofan annular member, having a plurality of slots therein, a disk having a plurality of notches in its periphery corresponding to the slots in the annularmember, means to hold the two in spaced relationship, a,

' cushion' abutting against the" ends of the glass adjacent the disk, an outwardly extending; rod on said; disk, threads cut thereon, a cap having a central opening which fits the said rod and a peripheral flange, a knob mounted onithefthreadsiof the rod to secure and hold said cap and periphery corresponding to the slots in the annular member, a plurality of rods, one end of which is secured to said annular member, the other end being attached to the said disk, an: outwardly extending rod on said disk, a cushion which abuts against the ends of the glass adjacent the disk, a cap which fits over the cushion and disk, and

foregoing specification. I

means to: secure and hold said. cap in position.

of strips of glass comprising an annular member, having a plurality of slots therein,

a disk. having a plurality of notches cut in its periphery corresponding to the slots in the annular member, one end of; the glass strips resting in the slots in the annular member, the other end resting in the notches in the disk means to hold the disk. and annular member in spacedrelationship,elastic and compressible means abutting; against the, ends of said glass strips and means to compress said last named'meansagainst the ends of the glass.

frame for lightingv units, formed In testimony; whereof I have signed the o'r'ro MOHR.
