WILLIAM ADAMS, OF SAFT FRANCISCO, CALIFORNIA.

CHANDELIER.

To all whom it may concern:

Be it known that I, WILLIAM ADAMS, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented certain new and useful Improvements in Chandeliers, of. which the following is a specification.

My invention relates to that class of chandeliers in which the lighting units, with their associated ray-directing means, are so mounted as to adapt them to be turned for either direct or indirect lighting, that is to say, to throw the light either down or up.

My invention is particularly applicable to what may be termed cluster chandeliers, in which a plurality of arms project from the shell-body of the chandelier, each arm carrying one or more lighting units; though it is also applicable to a single bracket fixture.

My invention has for its object the provision of a simple and practical novel means for permitting the reversal of the lightcarrying arm, and cont-rolling said reversal by asuitable stop and a lock, the latter of which may form an ornamental feature of the fixture, and be adapted for proportions yielding a proper balance to the design of the fixture as a whole.

To this end my invention consists in the novel rotatable and controllable connection of the light carrying arm, which I shall now fully describe by reference to the accompanying drawings in which Figure 1 is an elevation of a chandelier, showing but one arm, and indicating by dotted lines the reversed position of the lighting unit. Fig. 2 is an elevation, enlarged, of the rotatable arm-joint. Fig. 3 is a longitudinal section of the same. Fig. 41 is a cross section on line wa: of Fig. 2.

The chandelier here shown is, in the main, of common type, comprising the canopy 1, the stem 2, the shell-body 3 with its bottom knob 1, and a plurality of arms, one only be ing here shown, indicated by 5. It will be understood that each of the other arms is like the one shown and similarly mounted.

The outer extremity 6 of the arm 5 carries the lighting unit or lamp 7. It also carries the shade holder 8 and the shade 9 which latter constitutes the ray-directing means. The rotatable, controllable connection bet-ween the arm 5 and the shell-body 3 of the chandelier is as follows :Through the band 3 of the shell-body is fitted a sleeve 10 the inner end of which is solid and Specification of Letters Patent.

is tapped for a short nipple 11 which con nects it with stem tube 12. The outer end of the sleeve is formed with a ball 13, which is held pressed up against the shell-body band 3 by the nipple connection 11 at the inner end of the sleeve. The sleeve 11, within the cavity of the shell body 3 is cut out as shown at 14: through half its upper circumference.

The inner end of the arm 5 is fitted through the ball end 13 of the sleeve 10, and extends into said sleeve. It is mounted to turn on its axis in said ball and sleeve, and its inner extremity is fitted with a stud 15 which plays in the cut out portion 1 1 'of said sleeve. This stud serves as a stop to limit the movement of the arm 5 on its axis, enabling it to turn in either direction through 180 degrees. Said stud 15 also serves as a stop against the lineal withdrawalof the arm 5; and a collar 16 on the arm 5 bearing against the ball 13 serves as a stop to limit the lineal penetration of said arm. Thus said arm is seated and may be turned to a reverse position as indicated by the dotted lines in Fig. 1. Now, in order to lock the arm in its position at the limits of its rotary or axial movement, a set screw 17 is fitted to the ball-13 and impinges upon the arm. This set screw may be made of any ornamental design.

The operation is as follows: Suppose the lighting unit be in the position shown in full lines in Fig. 1, with its lamp and ray-directing shade turned upward for indirect lighting, and it be desired to turn them downward for direct lighting. The set screw 17 is relieved and the arm 5 is turned on its axis until the parts assume the position shown by the dotted lines. This movement is limited by the stud 15 playing in the cut out portion 14: of the sleeve 10, and said arm 5 is then looked in this limit by setting up the screw 17 again. The arm 5 may also, if desired, be locked in any intermediate position, by the set screw 17. By again releasing the set screw the parts may be turned back again, and limited and looked as described. By this construction a simple and practical rotary connection is made, which requires no particular instruction to operate.

The parts are well fitted and of good and workmanlike appearance. The ball end 13 of the sleeve 10 may be made in such proportion to the arm as to present a proper balance to the design of the fixture as a whole, and the set screw 17 may be as ornamental as desired.

I claim 1. In a chandelier, the combination of a body; an arm; a lighting unit and raydirecting means carried by the outer end of the arm; a fixed sleeve fitted in and projecting from the body, the projecting end being formed with an enlargement Which bears exteriorly on the body, the inner end of the light-carrying arm being seated to rotate on its axis in said sleeve; means carried by the arm and coacting with the sleeve ithin the body to both limit the axial movement of said arm and to lock said arm against outward lineal movement; means on the arm exterior to the sleeve and acting in conjunction with the enlargement of said sleeve to lock said arm against inward lineal movement; and means carried by the enlargement of the sleeve to fix the arm in the position to which it is turned.

2. In a chandelier, the combination of a body; an arm; a lighting unit and raydirecting means carried by the outer end of the arm; a fixed sleeve fitted in and projecting from the body, said sleeve having a semi-circumferential cut out portion lying within the body and having on its projecting end an enlargement which bears exteriorly on the body, the inner end of the; light-carrying arm being seated to rotate on its axis in said sleeve and its enlargement; a stud on the inner extremity of the arm, playing in the cut out portion of the sleeve, to limit the axial movement of said arm;

a collar on the arm bearing against the enlargement of the sleeve and acting in conjunction with the'stud to fix the arm against lineal movement in its seat; and means carried by the enlargement of the sleeve to lock said arm in the position to which it is turned.

3. In a chandelier, the combination of a body; an arm; a lighting unit and raydirecting means carried by the outer end of the arm; a fixed sleeve fitted in and projecting from the body, said sleeve having a semi-circumferential cut out portion lying Within the body and having on its projecting end an enlargement which bears exteriorly on the body, the inner end of the light-carrying arm being seated to rotate on its axis in said sleeve and its enlargement; a stud on the inner extremity of the arm, playing in the cut out portion of the sleeve, to limit the axial movement of said arm; a collar on the arm bearing against the enlargement of the sleeve and acting in conjunction with the stud to fix the arm against lineal movement in its seat; and a set screw in said enlargement of the sleeve impinging on the arm to lock said arm in the position to which it is turned.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

WILLIAM ADAMS.
