S. M. ISRAEL ADJUSTABLE SUPPORT FOR ELECTRIC LIGHT CANDLES Filed Aug. 22 1923 [PraeZ Federated No 2?, i923.

UNETE TATES SIDNEY M. ISRAEL, OF WOODI-IAVEN, NEW YORK.

ADJUSTABLE SUPPORT FOR ELECTRIC-LIGHT CANDLES.

Application filed August 22, 1923. Serial No. 658,744.

To all whom it my concern:

Be it known that I, SIDNEY M. ISRAEL, a citizen of the United States, and a resident of Woodhaven, county of Queens, city and State of New York, have invented certain new and useful-Improvements in Adjustable Supports for Electric-Light Candles, of which the following is a specification, sufficient to enable those skilled in the art to which the invention appertains to utilize the same.

y invention relates to the class of electric ight fixtures designated in my concurrent application Serial No. 612,928, filed January 16, 1923, which are intended to simulate the use of candles; and no imrovements are desi ed to afford a slmple, inexpensive, but e ective and substantial support for an incandescent candle lamp bulb, by means of which said lamp bulb may be conveniently adjusted as related to the other parts of the fixture, all as hereinafter fully set forth,--the invention, to this end, consisting in the specific construction, combination and arran ement of parts described and claimed, where y, the manipulation thereof is facilitated and rendered effective.

Inthe accompanying drawings I "exemplify a practical embodiment of the es sential features 'of my invention in an adjustable lamp support consisting of a onepiece basic section and a one-piece extension section, each of said sections being made from a blank of sheet metal, dieformed and bent into the requisite shapes, with interlocking parts as related to each other, although I do not limit myself to the identical configuration and construction thereof shown, since modifications in minor details and mechanical expedients may be resorted to with like result, and without departing from the spirit and intent of my invention in this respect.

With this understanding;

- Fi 1, represents a fiat View of the metallic b ank used in the formation of the adjustive section of In lamp support; and

.Fig. 2, what may e designated as a front view of said ad ustive section bent into re uisite shape;

ig. 3, is an upper end elevation of th part shown in Fig. 2;

Fig. 4, is a lower end elevation thereof;

Fig. 5, represents a flat view of the metallic blank used in the formation of the basic section of my lamp support; and

Fig. 6, what may be designated as a front view of said basic section bent into requisite shape;

Fig. 7, is an elevation of the upper end of the part shown in Fig. 6; and

Fig. 8, is an elevation of the lower end thereof;

Fig. 9, is a front view of the two sections of the support as assembled for use, and fully extended as related to each other;

Fig. 10, is a rear view of the parts as shown in Fig. 5; and

Fig. 11, a side elevation thereof;

F1g. 12, is a centrallongitudinal section taken upon plane of line 8-8 Fig. 5;

Fig. 13, is an elevation of the upper end of my support;

Fig. 14, is an elevation of the lower extremity thereof.

The lower basic or socket member B, or section of my extensible lam support is formed from a single blank 0 sheet metal, stamped into substantially the shape shown 1n Fig. 5, and is then bent up into tubular form as shown in the subsequent figures of the drawings' Said blank'B, is formed with lugs b, b, which are inturned for the purpose of malntaining the alignment of the ad ustable section A. The lower part of the blank B, is also formed with the lateral extensions b, b, which are inturned to form the tubular socket b, which is internally screw threaded as shown in Fig. 12, for attachment to the usual fixture, not shown.

The adjustable nipple section A, is formedwith lateral extensions (1, 0;, which on being inturned form the tubular nipple a, the upper end of which is peripherally screw threaded for engagement with an electric candle lam in the usual manner. Said adjustable nipple section A, is also formed with the lateral tongues a, a, at its lower extremity which, on being inturned, acts as stops to prevent the separation of the two sections A, B, when fully extended as related to each other as shown in Figs. 9, 10, 11 and 12 of the drawings, and more particularly in Fig. 9 thereof.

S, is a set screw engagin with a thread in the basic section B, and caring against the adjustable nipple section A, as shown more articularly in Fig. 12 of the drawing. This screw is preferably formed with form,

a knurled head to facilitate manipulation, although l do not wish to limit myself in this respect, as other forms of set screws maiy be substituted if desired.

t will be noted, of course, that the ad justable nipple section A, when in tubular diameter of the basic section B, so as to fit slidably therein.

My present construction and arran ment of parts is designed, to simpli y, cheapen and improve that set forth in my aforesaid concurrent application Serial No 612,928. A practical advantage obtained by spectiveparts.

my present structure is, dispensing with the necessity for slotting the lower basic section, and in having the set screw S, bear. onl against the nipple section A, thereby acting in conjunction with the lugs b, b, to retain the sections in the requisite relative positions.

' Another important advantage obtained by my present construction is dispensing with the lateral bracket arms on both sections of the holder, and forming the nipple end socket screw threads directly on their rel u'rthermom' by the use of the binding screw S, in conjunction with the retaining lugs b, b, I am enabled to attain a greater extent of adjustment between the parts. Another advantage in this connection is convenience or access to the set screw S.

By my present invention I attain a maxiis of less diameter than the tubular 1 ravages mum of simplicity and cheapness constrnction while facilitentirw manipulation.

It is to be noted in this connection that, aside from the set screw S, my present structure is free from protuberar both sections in axial alignment; parts may be die-formed exclusivel mg only the cutting of the screw and that the whole structure, considered in a unitary sense, is stronger, more rigid and substantial than heretofore.

What I claim as my invention and wish to secure by Letters Patent is:

As an article of manufacture, an adjustable support for electric lamps of the character designated, comprising a basic socket member formed of a single piece of sheet metal inturned into tubular form, and internally screw threaded at its lower extremity and formed with inturned lugs at the other extremity, and an adjustive nipple member formed of a single piece of sheet metal inturned into tubular form, and externally screw threaded at its upper extremity and formed with retaining lugs at its lower extremity, together with a binding screw in threaded engagement with the basic section and bearin against the adjustive nipple section, for t e purpose and substantially in the manner set forth.
