T at a 7mm 2'15. may concern Be it known th at 1, PAU J.j PFEIFER, a

citizen of the United States, residing at Cleveland, in the county of Cuyahoga and 5 State of Ohio, have invented certain new snu against and useful Improvements in Electric-Light Fixtures, of which the following is a spec fication.

This invention r lights and the obj elates to brackets for side ect of the" invention 'is to construct such brackets in such a way that the through them applied to a .ther object of a bracket of this and the i circuit wires may wall or an outlet box.

with at b in a well known way. The outer end of the arm B is formed in a novel way.

It has a bead or shoulder c which provides a seat for the cap i for the fastening rod E. Said bracket is D and it has .a support 8 ratented iuayie, 19:22.

also formed with an extension or lip 7 which carries a nipple F. The nipple is firmly 'attachedto the extension 7? by the flanges shown and it is also preferably soldered for additional security.

The'rod'E is headed at its outer end and its threaded inner end carriesa nut G which engages the crowfoot, spider or sup port H which is attached to the side wall or to the outlet box therein. rod the bracket may the support and it is surrounded by the its arm. In order to conceal the fastening device at the outer end of the bracket and produce ance, I employ a cap D which fitsover the end of the arm' and over the nipple. This cap is formed with an" opening which the outer end ofthe arm extends and with an opening at through whiclithe nipple projects.

Then the nut N .'s applied and screwed home in suchmanner as to firmly lock the cap in place. I

The circuit wires may be applied in any preferred manner either in the shop or when the bracket is being installed. These circuit wires are passed through the bracket and through the nipple in well known ways.

A very important feature of the invention is that it enables me to polish or finish the exposed parts of the brackets without danger of breaking projecting parts. The extension f which carries the nipple F need not be polished as it is'concealed by the cap when the parts are assembled. Heretofore in brackets of somewhat similar construction. when the outer end of the arm loose or supplemental was applied to the polishing wheels, and the arm was polished in the neighborhood of the nipple, the nipple was often broken oil which has been a serious obstacle, but according to my invention the extension of the arm is not polished but left in a rough condition. It will be further observed that a smooth and even finish is given to the exterior of the bracket, the outer end of the fastening rod being surrounded by the cap while in many other constructions the head of the rod was exposed. The cap is separable from the bracket and may be polished separately and given a fine finish. It is important that this part of the bracket should begiven the best finish possible.

It will also be observed that there are no parts employed for connecting the cap with the bracket. The lug e is formed integrally with the bracket arm. The nipple is firmly secured to the bracket, and the nut is made strong and durable as is apparent from. the drawings.

As shown in Figure 2, the cap is so formed around the opening d that to the bracket and when the nut is screwed home, the cap will firmly engage the outside .of the extension f. The nipple F may bev used to connect the bracket with a lamp socket, or the nut'may be used for that purpose. As shown, the nut carries a loop which forms no part of the subject matter herein claimed. By detaching the nut the cap may be easily removed, and the wires may be easily inspected or adjusted. There after the parts may be quickly reassembled.

f necessary, after the cap is removed, the fastening rod may be disconnected from its supportand the bracket as a whole withdrawn;

I claim as my invention:

1. An electric hollow arm formed at its outer end with a bead, a nipple carrying extension and an inwardly extending lug engaging a fastening rod; and a cap seated against said head and concealing said lug.

2. An electric light bracket comprising an arm formed at its outer end with a lug enwhen applied light bracket comprising a gaging a supporting rod and rying extension; a nipple in said extension, and a cap fitted on the outer end of the arm through which the nipple extends and which conceals the lug.

3. An electric light bracket comprising an arm formed at its outer end with a bead, a lug engaging a supporting rod, and a nipple carrying extension; a nipple in said extension, a cap resting against the bead and ex- 5. An electric light bracket comprising an arm, an integral projecting lip at the outer end of the arm, a nipple carriedby said lip, and a cap fitting over the outer end of the arm to conceal said lip, said cap having an opening through which the nipple extends.

6. An electric light bracket comprising an arm, a projecting lip at the outer end of said arm, a nipple carried by said lip, a cap fitting over the outer end of the arm to con- 'ceal said lip and having an opening through which the nipple extends, and means on the nipple directly the latter in place.

7 An electric light bracket comprising an arm, an integral projecting lip at the outer end of the arm, a nipple fastened in said lip, a cap fitting over the outer end ofthe arm and engaging said lip thereby concealing the same, and having an openingthrough which the nipple extends, and adjustable means on the nipple and directly engaging the cap to clamp. the parts in assembled relation.

In testimony whereof, I have hereunto subscribed my name.
