Application filed March 4, 1922. Serial No. 541,234. 2
To (ZZZ whom it may concern Be it known that LWALTER R. .KAHNs, 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 EXtQDSllOlGSHP- ports for Electric-Lamp Sockets, of which the following is a specification.
My invention relates to supports for lamp sockets in electric lighting fixtures, and
-while applicable to fixtures of different construction, it is particularly designed foruse in connection with electric candle fixtures in which the lamp socket is surrounded by a jacket or tube resembling a candle, the socket being supported in the upper endof the candle tube to hold the lamp in the proper relative position to the tube; these candle cylinders being of different'lengths, it is important that the socket supports be adjust able so that the socket, may be held in the proper position according to the height of the tube. i j. Adjustable supports have heretofore been made, but those in common uselack proper rigidity and-are inclined to wobble, and the object of my present invention is not only to remedy this objectionable feature, but also i to provide a support with a double adjustment, so that the support may be lengthened or shortened either at its top or bottom, or both if desired.
The details of the invention are hereinafter particularly described. I
In the accompanying drawing Figure 1 is a perspective view of the as sembled support, in actual size. V 1
Fig. 2 is an elevation of the upper'member detached, and in enlarged size.
Fig. 3 is an elevationof the lower bracketdetached, and enlarged.
Fig. 4 is an elevation of the link detached, and enlarged.
Fig. 5 is asection taken on thebroken line 5-5 of Fig. 1, but in larger size, and
Fig. 6 is a side view of the upper member showing a modified form for attachment to a lamp socket,'this view being also of enlar ed size.
imilar reference characters denote like parts throughout the several figures.
connecting Referring to the drawing, 10 denotes an,
angle bracket, its horizontal arm 11 being provided with a threaded stud 12, for attachment to a pipe terminal,'or other suitable means of support.
The longitudinal edges of the vertical arm 13, of the bracket 10 are bent over towards each other leaving a space 14, between them, i and also a space between these overturned portions and arm.
' 15 denotes a member to be connected with a lamp socket. The longitudinal edges of this member are bentover towards each other in the same manner as are the edges of the bracket 10, above described, leaving a space 16, between them corresponding in width with the space 14 between the overturned edges of the bracket. This member the flat body portion of this 15, is preferably formed from a single piece of sheet metal, and bent to'shape after being cut out. A recess 17 is cut in the upper end 5 formingtwo spaced arms or projections 18 and 19 in theends of which holes 20 are provided. These arms 18 and 19, are then bent at right angles to the body of the memher 15, and are to be secured to'the base of the lamp socketby screws, bolts orother suitable means, thus connecting the member .15, to the lamp socket.
21, indicates a link for adj ustably connecting the member 15 withthe bracket 10. This 7 *linkis formed from a strip of sheet metal. A
depression is made in one side its entire length, forming 'a central longitudinal groove 22, on that slde, and a central longiea I tudinal rib 23 on the opposite side, leaving a fiat'longitudinal edge 24 on either side of the" groove and rib. This link 21 is of a width and thickness at the outer edges to be passed between and under the overturned edges of the bracket 10, and member 15, and to be slidable in. each, the longitudinal rib 23, projecting into the spaces between the overturned edges of these members.
Adjacent each end of the link 21 there is provided athreaded hole 25, into each of which is screwed a binding screw 26, for clamping the link to the bracket 10 and member 15,in any position to which it may be adjusted, it being obvious that upon turning down the screws 26, their ends will press against the flat. body portions of the bracket or member 15, thereby forcing the flat'longitudinal edges of the link against the overturned edges of such member or members, tightly binding the parts together, which of course may be instantly released when desired, by turning the screw or screws in the opposite direction.
As a means for preventing the accidental withdrawl of the link from the member 15, I make a small central indenture in one side of the member 15, adjacent its lower end forming a projection 27, on the opposite side which projects into the longitudinal groove 22, and with which the binding screw in the upper end of the link will contact if drawn down suiliciently far, thus preventing the accidental separation of these parts. A similar projection 28 is formed in the upper end of the vertical arm of the bracket 10, for a similar purpos The formation of the upper end of the member 15 as shown in Fig. l and 2, is to provide for its connection to sockets now commonly in use in this class of lighting fixtures, but where it is desired to connect such member to lamp sockets provided at their lower ends with a threaded nipple, 1 provide the flanged or bent over upper end of the member 15 with a threaded end 29, to screw into the socket nipple, as illustrated in- Fig. 6. I
My invention provides against any possible wobble or lateral movement of the support, thereby holding the lamp socket steady in the position to which it may be adjusted. It also provides for the adjustment of the support either at the top or bottom, or both,
- which is of great importance, particularly vith candle tubes of extreme height, as the support may be lengthened to a much greater extent than has heretofore been possible. It will be readily seen, however, that for use with candle tubes of short or ordinary height, the lower end of the connecting link may be tightly clamped within the bracket in its lowermost position if desired, or it may even be permanently secured in such position.
I claim as my invention:
1. A support for an electric lamp socket, comprising three members, one member having its longitudinal edges over turned towards each other and provided at its upper end with means for attachment to the socket, the second member having similarly overturned edges and provided at its bottom with a stud for connection with a pipe terminal, the third member being inserted slidably under the folded edges of the first and second members, and means for clamp ing the same in that position.
2. A support for an electric lamp socket, comprising a member formed from a flat strip off metal,.having its longitudinal edges bent over towards each other leaving a between them, and provided at its upper end with means for attachment to the socket, an angle bracket provided with a stud for connection with a pipe terminal and having its: vertical side edges bent over towards each other leaving a space between them, and a link formed from a flat strip of metal provided with a central longitudinal rib on one side and a corresponding groove in its opposite side, said link passing under the bent over edges of said member and bracket and adjustably connecting'the same, the rib on said link projecting into the spaces between said bent over edges of the said member and bracket, and binding screws passing through a threaded hole in each end of said rib.
Signed by me this QZth'day of February, 1922.
