D. D. GORDON ADJUSTABLE CANDLE SOCKET MOUNTING Nov. 5, 1929.

Filed March 23, 1927 Patented Nov. 5 1929 UNITED STATES PATENT OFFICE DAVID J). GORDON, OF CHICAGO, I LInoIs, AssIGr'oR T0 ECONOMY FUSE AND MANU- FAC'IURING COMPANY, or CHICAGO, ILLINOIS, A CORPORATION on NEW YORK 'AIDJ'USTABLE OAIN'DLE SOCKET MOUNTING 7 Application filed March 23,

The present invention relates to adjustable candle socket mountings.

'More particularly, the present invention relates to electric devices of the type known in the art as candle sockets, commonly employing a cylindrical sleeve, simulating a candle. Said sleeves come of varying lengths and require the carrying in stock of different sizes of holding means for holding the usual socket for receiving the electric lamp.

Candle socket constructions frequently embody a witching mechanism for switching on and oil the electric lamp associated with the candle socket mechanism. The means for her secured to the conduit 10 at the'extremsupporting the socket containing the electric lamp and the switching mechanism should be rotatably adjustable independently of the vertical adjustability of the socket switching mechanism. I

An object of the present invention is to provide an adjustable candle socket mounting which permits a very large range in longitudinal adjustment of the light socketrelative to the electric fixture with which it is associated.

A further object is to provide an adjustable candlesocket mounting which is easy'to assemble and which, therefore,simplifies the work of the artisan or other person installing said candle socket mounting.

A further object is to provide a candle socket mounting having a wide range of adjustability in a longitudinal direction and which is also readily'adjustable in a circumferential direction.

Further objects will tion proceeds. I

Referring to the drawings- Figure 1 is a longitudinal sectional View of a candle socket mounting embodying the principles of the present invention;

Figure 2 is also a longitudinal sectional view of the structure shown in Figure 1, but taken at right angles to the plane shown in Figure 1;, i p g Figure-3 is a view in side elevation of a clamping member forming a part of the structure illustrated in Figures 1 and 2; and

Figure 4 is a sectional view taken along appear as the descripcooperating gripping members 17-17 1927. Serial No. 177,481.

as for example, a chandelier, wall bracket, or

other fixture. Secured to the conduit 10, near to the outer extremity thereof, is the cup 12 having the cylindrical wall 13and the shoulder 14. The numeral 15 indicates a sleeve member located within the wall 13 of the Cup 12 and resting upon the shoulder 14.

The numeral 16 indicates a clamping memity thereof. Said clamping member comprises the two gripping members 1717 and the intermediate portion 18. The extremity of the conduit 10 and the intermediate portion 18 of the clamping member 16 may have screw-threads whereby said clamplng member 16 may berigidly'positioned upon said conduit 10.

The clamping member16 provides adjustable holding means for a lampsocket indicated by the numeral 19. Said lamp socket 19 is adaptedto receive the lamp 20 and is provided at its other extremity with a cylindrical" shank 21, adapted to be gripped by the of the clamping member 16.

The lamp socket 19 is provided with a switching mechanism indicated by the numeral 22, which switching mechanism is il- 1 lust-rated as being of the pull chain variety, a pull chain 23 being illustrated, which chain extends through an aperture 23 in the cup 12.

The numeral 24 indicates sleeve adapted to encircle the gripping members 1717.

. Said sleeve 24 may have a substantially cylindrlcal interior conformation, or may be slightly conical to conform to the tapering conformation of the gripping members 1717. Said gripping members 1717,

. which may be formed of sheet metal, are preferably rounded, so that in cross-section they take the form of arcs of a circle.

, One of the gripping members 17 is provided with a plurality of spaced struck-out s5 pull portions or projections 2525, best illustrated in Figure 3. The inner surface of the cylindrical member 2a is provided with a recess 26 adapted to receive selectably one or another of the buttons 25.

Disposed diametrically opposite to the recess 26 in the cylindrical sleeve 2a is the screwthreaded aperture 27 containing the set screw 28, which set screw is adapted to engage the corresponding gripping member 17.

Located preferably, though not necessarily, in each of the gripping members 1717, a short distance above each button 25 (with the exception of the uppermost button 25) is the saw-mark or depression 29.

The mode of operation of the present invention will be clear without detailed explanation. It will be clear that the clamping member 16 may be screwed down upon the conduit 10, whereby to be rigidly secured in position upon said conduit 10. The shank 21 of the lamp'socket 19 will be positioned between the extremities of the gripping members 17-17, the set screw 28 being loosened slightly to permit the ready insertion of said shank 21 within said gripping members 17-17. The uppermost projection 25 will be disposed within the recess 26 of the inner wall of the sleeve 24, and the set screw 28 will be turned home to hold the gripping members 17 17 in tight engagement with the shank 21 of the lamp socket 19.

It will be understood that the invention permits a considerable range of adjustment in the position of the lamp socket 19 by reason of the fact that the shank 21 may be gripped at any preferred region throughout the length of said shank 21. ldoreover, the switching mechanism 22 may be disposed at the proper angle to allow the pull chain 23' to hang in a substantially vertical plane and to be disposed at any preferred position relative to the conduit 10.

- or near anyone of the regions 29-29, where- By reason of the plurality of projections 25 and by reason of the saw marks or depressions 29-29, a greatly increased range of adjustability is had, due to the fact that the gripping members 17 17 may be cut on" at by said gripping members may be varied in length. The advantage of this construction will be obvious. The electrical artisan need carry with him only one size of clamping member 16. If the job which he has at hand calls for a fitting for a relatively short sleeve member 15. he can readil cutoi the ri ping members 1717 at or near the proper regions, having available at the gripping extremities of said members 17-17 a button 25 for holding the sleeve 24 in position.

By reason of the present invention, therefore, the number of clamping members 16 which must be stocked by the electrical sup ply house in order to meet the demands of the trade is reduced to a minimum.

The present invention provides a firm gripping means which is simple to install and which efiectually meets the demands of ordinary service conditions.

.Though a preferred embodiment of the present invention has been described in detail, many modifications will occur to those skilled in the art. It is intended to cover all such modifications that fall within the scope of the appended claims.
