COMBINED ADJUSTABLE BOWL-HANGER AND LAMP-SOCKET SUPPORT FOR LIGHTING- FIXTURES. I

I Application filed September 16, 1915.

T 0 all whom it may concern:

Be it known that I, WALTER R. KAHNS, a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have invented an Improvement in Combined Adjustable Bowl-Hangers and Lamp-Socket Supports for Lighting-Fixtures, of which the following is a specification.

My invention is particularly applicable to lighting fixtures for producing semi-indirect lighting effects; it is of the clamp character, and its object is to provide a combined bowl hanger and socket support which may be adjusted to glass-ware of varying curves and thickness, and also to provide means for supporting a lamp outside the bowl when desired.

The details of the invention are hereinafter particularly described.

In the accompanying drawing: Figure 1, is an elevation illustrating my invention applied to a bowl of the mushroom type, and supporting an incandescent electric lamp outside the bowl, the bowl being in section. Fig. 2, is an elevation illustrating my invention applied to a bowl of the hemispherical type, the supporting arm for an outside lamp being removed. Fig. 3, is a rear elevation of the hanger with the hook and inside socket support removed. Fig. 4, is an elevation of the hook and integral socket support detached. Fig. 5, is an elevation of the outside socket supporting arm detached, and Fig. 6, is a sectional view taken on the line 6-6 of Fig. 3, a fragment of a bowl being added.

Similar reference characters denote like parts throughout the several views.

10, indicates a bowl of transparent material, such as employed in fixtures for producing a semi-indirect lighting effect. These bowls are of various curves and thickness.

11, designates the hanger which may be of any desired ornamental character, the lower portion of which is curved inwardly and provided with an arm 12 at each side extended in opposite directions. On the inner side of this hanger 11, and at a predetermined distance from its top there is a bifurcated lug 13, each section of which is provided with an opening 14 which openings are in alinement.

15, indicates a bar having its upper end Specification of Letters Patent.

Serial No. 50,950.

bent over to form a hook 16, and provided at its lower end with two oppositely curved branches 17, and 18. Upon the free end of the branch 17, there is a hollow stud 19,

Upon the bar 15, at a predetermined point below the hook 16, there is a lug 20, pro ect1ng in the same direction as the branch 18. There is a lateral opening 21, through this lug 20. This lug 20, fits between the sections of the bifurcated lug 13, on the hanger 11, and is pivotally se cured therein by a rivet or screw 22. At predetermined points above and below the pivotal connection between the hanger 11, and bar 15, said bar is provided with screwthreaded holes 23, and 24, which receive the set screws 25, and 26, respectively.

27, designates an arm detachably se cured to the hanger 11. This arm may be of any desired ornamental character and at its free end is curved upwardly to form a hook 28. I have shown this arm 27, provided with a screw-threaded recess 29, adjacent its end opposite the hook 28. This recess 29, registers with an opening 30, in the hanger 11, through which passes a screw 31, which is screwed into the recess 29, thus detachably connecting said arm to the hanger.

32, indicates a suspending chain connected with the hook 16, upon the bar 15.

38, designates an incandescent electric lamp suspended from the hook 28 on the arm 27, by means of a loop 34, provided with a hollow screw-threaded stud 85, upon which the lamp socket is screwed.

The screw-threaded stud 19, upon the end of the branch 17, of the bar 15, is to receive and support a lamp socket within the bowl 10.

It will of course be understood that the conductor Wires (which have been omitted for clearness) pass to the lamps through the hollow studs 19, and 35, respectively.

In Fig. 1, of the drawing, I have shown my invention applied to a bowl of the mushroom type. In this instance after the rim of the bowl 10, has been placed between the hanger 11, and the bar 15, the set screw 25, is turned so that its end contacts with the hanger, swinging said hanger on the pivot 31, and moving its inturned lower portion with the extended arms 12 under the rim of the bowl, while the branch 18, at the lower end of the bar 15, is swung into contact with the inner surface of the bowl; the set screw 26, is then turned until its end comes into contact with the inner surface of the bowl, care being taken to so adjust the device that no undue pressure is applied to the glassware, while at the sametime the bowl is securely clamped. I prefer to form a recess 36, in the upper rear surface of the hanger 11, which provides a bearing for the end of "the screw 25.

In Fig. 2, of the drawing, I have shown the'device applied to a bowl of the hemispherical type. In this instance the screw 25, isnot necessary and is preferably entirely removed, as shown in this figure, but

it may be left in the hole 23, if. desired, with its point withdrawn suflicient-ly so as not to project beyond the oppositeside of the bar 15. The hooked end 16, of the bar being connected with the suspending chain 32, when the flanged or curved rimof the bowl 10, is placed upon the inturned lower part of. the hanger and its extended sidearms 12, the pull of the chain and the weight of the bowl swing the upper parts of the bar and hanger into contact in consequence of their pivotal connection, bringing the branch 18, at the lower end of the bar into contact with the inner surface of the bowl and thus automatically clamp the bowl.

As a precautionary measure, should the tension of the chain be relaxed or removed, the screw 26, is turned to bear against the inner surface of the bowl, as shown.

It will be readily seen that my-improved clamp may be easily adjusted to engage bowls of various curves, and thickness, whether the rim of the bowl is flat or curved more or less.

In Fig. 6, of the drawing, I have shown a fragment of a bowl having a rim which rests fiat upon the inturned lower end of the hanger and its side arms.

The detachable arm 27, provides a means of combining direct and semi-indirect lighting in instances where such combined effect is desired, but as such effect is not always desired, the detachability of the arm 27, is of great advantage as the arm may be easily attached or removed.

My invention renders it unnecessary to provide different hangers and hooks to conform to the differences in the curves and thickness of bowls, as heretofore required.

I claim as my invention:
