HOLDER FOR LIGHT-TRANSMITTING BOWLS AND REFLECTORS.

Specification of Letters Patent.

- Application filed June 13, 1917. Serial No. 174,425

To all whom it may concern:

Be it known that I, EDWIN L. WHITE, a citizen of the United States, residing at the borough of Brooklyn, in the county of Kings, city and State of New York, have invented an Improvement in Holders for mitting Bowls and Reflectors, of which the following is a specification.

My invention relates to holders for light transmitting bowls and reflectors employed in lighting fixtures of the character producing a semi-indirect lighting efiect.

Holders have heretofore been made comprising a sheet metal top adapted for connection with a socket cover, with two downwardly extending oppositely bowed arms connected at their upper ends to said top by solder or rivets and connected at their lower ends in the same manner to a cupshaped bottom member of sheet metal having a flared top; such holders are placed inside the bowl, with the bottom member projecting through an opening in the bowl, the flared top of said bottom member bearing against the inner surface of the bowl. Such hangers are not adapted for supporting a reflector above the bowl, and furthermore in practice it has been found that the arms very often become loose or broken away from the top or bottom member or both, rendering the holder unsafe or useless, and the lower inner dish-shaped member forms a receptacle for dust or other foreign matter rendering it necessary to detach the holder for cleaning. The object of my present invention is to provide a holder that will not only support a bowl, but also support a reflector above the bowl and at the same time form an adjustable support for a lamp socket, by which the lamp may be adjusted for use wit 1 glassware of various sizes and shapes and furthermore providing a strong unbreakable connection for thearms both at top and bottom, also dispensing with the cup-shaped bottom.

In the accompanying drawing:

Figure 1 is an elevation partly in section, showing my improved holder connected with a hanging fixture. 3

Fig. 2 is a plan view of the holder detached.

Fig. 3 is an inverted plan view of the same,

I the arms being cut away on the broken line 33 of Fig. l.

Fig. 5 is an elevation of the upper ends of the arms before they are connected with the rlng, and

Fig. 6 is a plan view of the same.

Flgs. 1 and 2 are in reduced size, while in Figs. 3, 4:, 5 and 6 the parts are shown infull size.

10,-1ndicates an upper ring of comparatively thick metal interiorly threaded and upon the underside of which two transverse grooves 11, are cut, one at each side of the threaded opening.

12, indicates a lower ring of similar construction, the grooves 14 being made in its top surface. A 1

15, and 16, denote two wire arms, which at a predetermined distance from their upper and lower ends are bent vertically as at 17 and 18, then horizontally toward each other as at 19 and 20 which horizontal portions are bent at the center in opposite directions as at 21 and 22, then vertically as at 23 and 24, the extreme ends being out.- turned at aninclination as at 25 and 26.

.The two latter bends being made down- Patented Jan. 1,1918.

wardly at the upper ends of the arms, and

upwardly attheir lower ends.

The bent portion at 21 in the arm 15 is inserted into one of the grooves 11 on the underside of the upper ring 10, and the bend at 22, in the arm 16 is inserted into the other groove 11 in the same ring, after which the outer walls of the grooves are overturned upon the wires within the respective grooves K and hammered down, firmly securing the upper portions of the arms to the ring 10.

The-lower portions of the arms are secured to the .lower ring 12 in the same manner, that is, the bent portion at 21 in the arm 15 is inserted into one of the grooves in the upper surface of the ring 12, and the bend at 22 in the arm 16 is inserted into the other groove in the same ring, the metal of the ring 12 then being overturned upon the wires and hammered down thereon.

The wire arms between the vertical bends 17 and 18 are more or less curved or bowed in opposite directions according to the shape or size of the glassware with which the hanger is to be used.

With the arms secured to the upper ring 10, as described, the vertical bends 17, 18, 23 and 24 are equally spaced from each other and from the ring, while the inclined bends at 25 and 26 correspond with the curvature of the arms immediately below the vertical bends 17 and 18, therefore the upper end of the holder is adapted to being inserted into the neck of a dome or reflector 27 from below,-the inclined bends 25 and 26 and the outwardly bowed portions of the'arms 15 and 16 immediately below the vertical bends 17 and 18 forming seats for the dome or reflector.

The lower portions of the arms 15 and 16, being connected with the ring' 12 in the same manner as their upper portions with the ring 10, and having like bends, the lower end of the holder is adapted to ass into the opening in the bottom of a bow 28 with the inclined bends 25 and 26 conforming to and bearing against the inner surface of the bowl adjacent the opening. j

A cup 29 supports the bowl 28 there being a screw 30, which passes through a hole in the bottom of the cup and into the threaded opening in the ring 12.

This screw is of a length to allow for. the adjustment of the cup nearer to or farther from the bottom of the holder.

31, denotes an adjustable socket support. This consists of an exteriorly threaded tube fitting into the threaded opening in the ring 10. The lamp socket 32 is attached to the lower ,end of this tube, and at its'upper end there is secured an eye. to receive thesuspending chain 34:.

The conductor wires (not shown) pass through an opening in the base of the eye 33 and through the tube. 31 to the socket 32.

35 indicates an electric lamp.

It will be seen that by. rotating the threaded tube 31 within the threaded opening in the ring 10, the lamp-socket and lamp can be .raised or lowered to adjust its. position for various sizes or shapes of glassware, and this arrangement also allows for the use of larger watt lamps in holders of the same length than heretofore.

If desired a shell-cap 36 may be employed to fit over the neck of the dome or reflector 27 as shown in Fig. 1. This will also conceal the adjustable socket support 31 and give the fixture a more ornamental appearance.

My invention provides a holdercapable of supporting both a bowl and dome or re flector, it provides a connection for-both ends of the arms that is impossible of becoming loose or detached, it provides an adjustable socket support whereby the lamp may be readily adjusted when desired, and larger iamps may be used; it furthermore dispenses with the cup heretofore commonly connected the lower ends of the arms in tures, comprising two interiorly threaded rings in spaced vertical alinement, each provided with grooves, arms extending between the same and secured thereto within said grooves, the upper ends of said arms extending therefrom in opposite directions and bent to form spaced seats for a dome or reflector, and an exteriorly threaded tube fitted into the threaded opening in said upper ring forming an adjustable socket support.

3. A holder for glassware in lighting fix tures, comprising two rings in spaced vertical alinement, each provided with grooves, arms extending between the same and so cured thereto within said grooves, the upper ends of said arms extending therefrom in opposite directions and bent to form spaced seats for a dome or reflector, the lower ends of the arms being shaped to fit into the nech: of a bowl and contact with its inner lower surface.

4-. A. holder for glassware in lighting fixtures, comprising two interiorly threaded rings in spaced vertical alinement, each provided with grooves, arms extending between the same and secured thereto within said grooves, the upper ends of said arms ex tending therefrom in opposite directions and bent to form spaced seats for a dome or teflector, the lower ends of the arms being shaped to lit into the neck of a bowl and contact with its inner lower surface, and an exteriorly threaded tube titted into the threaded opening in said upper ring form ing an adjustable socket support.

5. in a lighting fixture and in combina-- tion, a dome or reflector, a bowl, a holder for said reflector and bowl comprising two rings in s aced vertical alinement, each. provided wit. grooves, arms extending between the same and secured thereto within said grooves, the upper ends ot said arms entered ing therefrom in opposite directions and bent to form spaced seats for said dome or reflector, the tower portion of the arms being within the bowl and shaped to fit into its neck and contact with its lower inner surface, a cup fitted over the bottom ot the bowl, and a screw connecting said cap the lower ring.

6. in a lighting fixture and in combination, a or reflector, a bowl, a holder for said reflector and bowl comprisin two interiorly threaded rings in space vertical ulinement, each provided with grooves, arms extending between'the same and secured thereto within said grooves, the upper ends of said arms extending from the ring in opposite directions and bent to form spaced seats for said dome or reflector, the lower portion of the arms'being within the bowl and shaped to fit into its neck and contact with its lower inner surface, a cup fitted over the bottom of the bowl, a screw 'connecting said cup with the lower ring, and an adjustable socket support fitted within the threaded opening in said upper ring.
