SCREWLESS GLOBE SUPPORT.

Application filed December 5, 1923. Serial No. 678,567.

To aZZ whom it may concern:

Be it known that I, Crmnnns C. TVA):- BAUGH, a citizen of the United States, residing at New Yorkcity, in the county of New York and State of New York, have invented acertain new and useful Improvement in Screwless Globe Supports,v of which the following is the specification.

My inventionrelates to that class of de vices which are designed to support the onepiece glass globes which are so largely in use for lighting purposes at the present time, and has for its object to provide a de-- vice which will always support the globe securely and yet on which there will be no machlne work such as is required for those holders which utilize screws to support the globe and to accomplish the same in an inexpensive manner.

My means of accomplishing the foregoing objects may be more readily understood in the accompanying drawings which are hereunto annexed and are a part of this specification:

Fig. 1 is a side elevation of my improvement, part of the wall being broken away so as to show the interior construction.

Fig. 2 is a detailed View of the bell-shaped member.

Fig. 3 is a bottom view of the same.

Fi at is a side elevation of the annular member.

Fig. 5 is a bottom view of the same.

Fig. 6 is an enlarged fragmentary detailed View of a portion of one of the lugs of the annular member showing the locking projection.

The same reference numerals refer to similar parts throughout the entire description.

As shown in the drawings, my holder comprises a bell-shaped member 1 to which may be secured the standard eye 2, indicated by dotted lines in Fig. 1, to which the electric light socket 3, also shown by dotted lines, is secured. This bell-shaped member is provided with a shoulder 4 and at its lower edge is provided with a pair of rigidly extending

lugs

5 and 6, which are diametrically opposite to each other and the diameter of the lower portion of the bell-shaped member is of a size which will permit it to be inserted into the globe to be supported.

An annular member 7, clearly shown in Fig. 4, the side walls 8 of which are fitted to and telescope the side walis 9 of the bellshaped member; This annulus is provided with radially extending

lugs

10 and 11 which approximately fill the space intermediate the tions formed approximately at the corners of the

lugs

10 and 11, where they join the lower part of the wall 8.

It W111 be obvious to persons skilled in. the

art that if the bell-shaped member were the same diameter as the

lugs

5 and 6, it would be impossible to insert it inside of a globe and that when the space intermediate these lugs is filled by the lugs formed on the annular member 7 it cannot be inserted in the neck of the globe. The manner of mounting is therefore to turn the annular member upon the bell-shaped member until the lugs coinciderwhen it will be apparent that the device I will present the appearance shown in Fig.

when it can, by being tipped to one side, be

inserted into the neck of the globe.

, The annular member is then rotated upon the bell-shaped member until the

lugs

10 and 11 are in the spaces intermediatethe

lugs

5 and 6. When they reach this position, the detents 12 will automatically prevent the rotation of the annular member until it is lifted up so that the globe will be held securely in position and cannot possibly be dislodged or drop as frequently occurs where screw fastenings are employed as these fastenings loosen from the chandelier in the buildings where the fixtures are employed.

I provide an annular cap 13 which rests upon the shoulder a, being provided with a flange 14, which isfitted thereto. The outer edge 15 of this annular member rests upon the globe and presents a very neatand satisfactory appearance when the holder is in position.

Having described my invention, what 1 claim as new and desire to secure by Letters Patent of the United States is:

1. A globe holder comprising a bell-shaped member having two radially projecting lugs diametrically opposite. to each other, an annular member which telescopes said bellshaped member, radially projecting lugs thereon at diametrically opposite points which approximately fill the space intermediate the first-named lugs, projections adjacent the corner Where said lugs join the annulus. i

2. A globeholder comprisingabell-shaped member having two radially projecting lugs diametrically opposite to each other, an annular member Which telescopes said bellshaped member, radially projecting lugs at diametrically opposite points which approximately fill the space intermediate the first-named lug, means to 1001: said annulus against rotation. j

3. A globe holder comprising a bell-shaped member having two radially projecting lugs diametrically opposite to each other, an annular member which telescopes said bellshaped member, radially projecting lugs at diametrically opposite points which approXi1nately fill the space intermediate the first-named lug, means to lock said annulus 20 against rotation, a cap which fits said bellshaped member above said annular member.

4. A globe holder comprising a bell-shaped member, a shoulder formed thereon, radially projectinglugs diametrically opposite each other, formed on the lower edge of said member, an annular member, the walls of which are fitted to and coincide withthe walls of the bell-shaped member below said shoulder, a flange thereon which rests upon said shoulder, radially projecting lugs on said annulus at diametrically opposite points, which approximately fill the space intermediate the first-named lugs, locking means on said annulus to prevent its rotation.

5. A globe holder comprising abell-shaped member, a shoulder formed thereon, radially projecting lugs diametrically opposite each other, formed on the lower edge of said' member, an annular member, the walls of which are fitted to and coincide with the v walls of the bell-shaped member below said;

shoulder, a flange thereon which restsupon said shoulder, radially projecting lugs on said annulus at diametrically opposite points, which approximately fill the space intermediate the first-named lugs, locking means on said annulus to prevent its rota tlon, an annular cap which telescopes said bell-shaped member and rests upon said shoulder.
