HOLDER FOR LIGHT-TRANSMITTING BOWLS.

Specification of Letters Patent.

Patented Jan. 8, 191%.

Application filed May 19, 1917. Serial No. 169,610.

To all whom it may concern:

Be it known that I, EDWIN L. VVIIITE, acitizen of the United States, residing at the borough of Brooklyn, in the county of Kings, city and State ofNew York, have invented an Improvement in Holders for Light-Transmitting Bowls, of which the following is a specification.

My invention relates to holders for light transmitting bowls employed in lighting fixtures of the character producing a semiindircct lighting effect, and adapted for connection with a socket cover or shell in ceiling lights, hanging lights or upright fixtures.

Holders of this character have heretofore been made comprising a ring-shaped top adapted for connection with a socket cover,

with two downwardly extending oppositely bowed arms connected at their upper ends to said ring by solder or rivets and connected at their lower ends in the same manner to a dish-shaped bottom member of solid sheet metal having a flared top, with central opening in the bottom through which passes a screw; 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, there being'a cup-shaped member with a central opening for the passage of the said screw placed over the outer surface of the bottom of the bowl, and a nut screwed upon the projecting end of the screw for holding the bowl between said outer member and said inner lower member.

In practice it has been found that the connecting 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 mem ber forms a receptacle for dust or other foreign matter rendering it necessaryto detach the holder for cleaning. The ob ect of my present invention is to overcome these difficulties and consists in providing a strong and secure attachment of the arms to the top ring, and an unbreakable connection between the lower ends of the arms in such manner as to render the employment of the inner lower dish-shaped member entirely unnecessary, thereby greatly economizing in material and cost of manufacture, while a superior holder for the purpose intended is produced.

In the accompanying drawing:

Figure 1 is an elevation partly in section, showing my improved holder attached to a hanging fixture.

Fig. 2 is a sectional view taken on the broken line 22 of Fig. 1, the globe being removed. I

Fig. 3 is an elevation of the hub before its connection with the arms.

Fig. 4 is a plan view of the same.

Fig. 5 is an elevation of the lower ends of the arms before they are connected with the hub.

Fig. 6 is a plan view of the same.

F 7 is a plan view of the top ring with the arms attached thereto.

Fig. 8 is a vertical section of the same, and

Fig. 9 is an elevation showing the screw and hub integral.

Similar reference characters denote like parts throughout the several figures.

10. indicates a concave ring having an inturned annular flange 11, at its top which flange is provided with oppositely disposed slots 12 and 13. The bottom of the ring 10 is of larger diameter than the top and its edge is preferably overturned to stiffen it.

14 and 15 denote two arms, the upper portion of which adjacent their ends being preferably flattened and bent to conform to the interior shape of the ring 10. The extreme upper ends of these flattened portions of the arms are preferably reduced in width of a size to pass through and fit within the slots 12 and 13 of the flange 11, their projecting ends being bent over upon the top of said flange.

In addition to such connection I also preferably rivet the arms to the ring as at 16 and 17 or they may be soldered at such points.

These oppositely disposed arms extend downwardly from the ring 10 to any desired extent and in more or less oppositelv bowed form according to the size or shape of the bowl to be supported.

At a predetermined distance from their lower ends each of the arms 14. and 15' are bent vertically. as at 18, then horizontally as at 19, which horizontal portion is bent at its center as at 20, (such bends being made in opposite directions in the respective transverse recesses 25.

21, and finally at an outward and upward inclination as at 22.

23, indicates a metallic hub havinga central threaded opening 2% to receive a screw 29.

In the top of the hub there are two spaced The bent portions 20, of the respective arms 14 and 15 are inserted into said recesses, and that portion of the hub outward of the recesses is overturned upon said bent portions of the arms, thus securely fastening the lower portions of the arms to said hub.

WVith the arms thus permanently secured to the hub the four vertical portions 18 and 21 of the arms are equally spaced and adapted to pass into and fit the opening 26 in the bottom of the bowl 27, the inclined ends 22 of the arms bearing against the interior surface of the bowl with resilient pressure.

The bottom of the bowl rests within or upon the cup 28 which is provided with a central hole for the passage of a screw 29 upon the projecting end of which is screwed a nut 30, whereby the bowl is held in posi tion and the cup secured to the arms. It will be understood that the screw may be made integral with the hub as illustrated in Fig. 9.

31, indicates a socket cover to which the ring 10 is held by set screws 32. 33 denotes an electric lamp, and 34: the suspending chain.

While I have illustrated my improved holder as connected to a suspended fixture, it will be seen that it is equally applicable to ceiling lights or upright or portable fixtures without change, and is easily placed in position where fixtures are, already installed. There is no danger of the. arms be-- coming loose or detached; the common solid sheet metal bottom cup is dispensed with,

greatly economizing in material and cost of manufacture and lessening the risk of injury tov the glassware as. the. inclined ends 22 of the arms possess a certain amount of spring and therefore do not bear against the inner surface of the globe with the same rigidity as the old solid sheet metal cup,

and there is no receptacle at this point for,

the collection of dust or other foreign matters.

comprising a, ring, arms secured at, their upper ends to said ring on opposite sides thereof and extending downwardly therefrom, the lower ends of said arms being bent toward each other in a horizontal line and then at right angles in an opposite direction, a hub having recesses in its top into which the bent lower portions of said arms are inserted and the metal of the hub overturned upon said arms to secure them within said recesses.

2. A holder for bowls in lighting fixtures, comprising a concave ring provided with an inturned annular flange at its top and oppositely disposed slots in said flange, arms flattened at their upper ends and bent to conform to the inner surface of said ring, their extreme upper ends being passed through said slots and overturned upon the top of said flange, said arms extending downwardly from said ring, and a hublprovided with recesses into which the lower portions of said arms are secured.

8. A holder for bowls in lighting fixtures, comprising a concave ring provided with an inturned annular flange at its top and oppositely disposed slots in said flange, arms flattened at their upper ends and bent to conform to the inner surface of said ring, their extreme upper ends being passed through said slots and overturned upon the downwardly from said ring their lower ends top of said flange, said arms extending being bent toward each other in a horizontal line and then at right angles in an opposite direction, a hub having recesses in itstop into wh ch the bent lower portions of sa d arms are inserted and the metal of the hub overturned upon said arms to. secure them within said recesses. V

4. In a lighting fixture and in combination, an electric lamp and socket, means for supporting the same, a socket cover, a ring connected w th said socket cover, arms secured at their upper ends to said ring on opposite sides thereof and extending down.- wardly therefrom, the lower ends of saidv arms being bent toward each other in a. horizontal, line and. then at right angles in an opposite direction, a hub provided with recesses into which such bent portions of the arms are inserted. and thesurrounding metal of "the, hub overturned upon said portions. of the arms to secure them withinsaid recesses, a bowl surrounding said arms and provided with an opening in its bottom into which said hub and the lower portions of the arms are inserted, a cupv within which the bottom of the. bowl rests, and means for removably connecting the cup with said hub. Signed by me this 11th day-of May, 1917. v EDWIN L; ,WHITE.
