IMPROVEMENT IN LAMP-BRACKETS.

Specification forming part of Letters Patent No. 198,118, dated December 1l, 1877 application led April 4, 1877.

To all whom it may concern:

Be it known that we, ALBERT D. J UDD'and EDWARD M. J UDD, of New Haven, in the State of Connecticut, have invented an I1nprovenient in Brackets for Lamps, 85o., ofl which the following is a specification:

Our improvement is made for sustaining the bracket upon pivots that are both above and below the bracket-arm, so as to increase `the strength of the pivot, and the pivot or wallplate is cast with the bearings for the pivot to avoid the expense of boring the holes. At the end of the bracket is a vertical hole, into which a'central vertical pin at the bottom of the reservoir-cup passes, so that said cup and its reservoir can be revolved around upon this pin. r

The reflector is supported so that it may be positioned at either side of the lamp, which cannot be done where the reflector is on the bracket or on the reservoir-holder that has a support at one side, as heretofore used.

In the drawing, Figure l is an elevation of the bracket, with the cup and wall-plate in section. Fig. 2 is an elevation of the wallplate, and Fig. 3 is a plan of the font-cup.

The bracket a is of any desired shape. At one end it has the pivot-studs b c, projecting' above and below, and upon these the bracket swings.

The wall-plate d is cast with an open loop, e, into which-the pivot-pin bis slipped up. The wall-plate is also made with a step at i,

4upon which the lower end of the pivot-pin c rests, and it is slightly channeled for the rounded end of the bracket and the cylindrical surface of the pivot c.

The retaining-plate f is adapted to sit over the pivot c, to hold it in position7 and the edges of the plate fare within the recessed surface of the wall-plate d, or between ribs that are provided for it, and the plate f is either riveted to d at 2, or secured by the attaching-screw at l, or both.

By this construction the parts can be cast ready for use, and do not require separate tting or boring.

The metal cup k, for the font. or reservoir, is to be of a shape adapted to receive such reservoir, and it is connected with the bracket a by a vertical central pin, t, running into the bracket, upon which the cup and the reservoir can be revolved entirely around.

At one side of the Cup k is the movable reilector-holder u, that is adapted to receive the reflector for the lamp. rlhis holder u is adapted to turn upon the vertical pin t, either with the lamp-cup lf, to which it is connected by the lower end entering the socketw, or the bracket may extend down to the pin t, and. terminate with an eye aroinid that pin, as shown by dotted lines. y

By this construction the lamp, cup, and rellector can be revolved on the central vertical pin, so as to direct the light to any desired part of the roorn, regardless of the direction of the bracket or chandelierarm upon which the lamp may be sustained. This is very converlicht, aud it also allows the reflector to be used as a screen or shade, to prevent the light reaching a bed or location from which it is to be shielded.

We claim as our invention- '1. The combination, with the bracket a and its pivots b and c, of the wall-plate d, and -retaining-platef, substantially as set forth.

2. The combination, with the bracket a, having a hole at its outer end, the metallic fontcup 7c and its central pivot-pin entering such hole, and the reilector-holder, supported as specified, so that the lamp and reflector can be entirely-revolved upon said central pivot-l 'pin, as set forth.

Signed by us this 29th day of March, A. D. 187 7
