No. 431.820. Patented July 1, 1890.

UNITED STATES PATENT OFFICE.

SIGMUND BERGMANN, OF NElV YORK, N. Y.

ELECTRIC-LAMP FIXTURE.

SPECIFICATION forming part of Letters Patent No. 431,320, dated July 1, 1890.

Application filed March 3, 1890. Serial No. 342,503. (No model.)

To all whom it may concern.-

Be it known that I, SIGMUND BERGMANN, of New York, county and State of New York, have invented a certain new and useful Improvement in Electric Lamp Fixtures, of which the following is a specification.

This invention relates to fixtures for electric lamps; and it consists in providing the fixture with a seat within which an electric cut-out may be secured.

I will describe a fixture embodying my improvement and then point out the novel features in claims.

In the accompanying drawings, Figure 1 shows a fixture or bracket-arm embodying my improvement with a cutout secured in place. Fig. 2 is a side view of a portion of an arm with the cut-out removed, and Fig. 3 is a top or plan view of the same.

Similar letters of reference designate corresponding parts in all the figures.

Referring by letter to the drawings, A designates a tubular arm for an eleetric-lan1p iixture or bracket. 13 is the seat for a cutout, and C shows a cut-out secured in place.

The cut-out C may be of any desired construction, and as its construction is not a feature of the present claim a detailed description thereof is not deemed necessary.

In a pending application, Serial No. 340,700, I describe andclaim a cut-out adapted for use herein.

The arm A may be of any con figuration or design, and obviously the cut-out seat B may be placed in any desirable part of it. The seat 13 is here shown as a frame or ring consisting of the outwardly-curved arms a, having perforated bosses a at opposite sides, to

which the adjacent ends of the tubular arm A are attached. I have here shown the'bosses A in the form of sockets and the ends of the arms seated therein and rigidly attached thereto by brazing or otherwise, so that the seat in effect is an integral part of the arm. In fact, the arms a may be formed by cutting away a portion of the sides of a tubular arm and curving the strips of metal formed thereby outwardly. The arms a have transverse channels a in their inner surface to receive the frame of a cut-out and prevent the same from turning within the seat. As a means for rcmovably securing a cut-out within the seat, the arms a are perforated at a for the passage of screws a. At one side of each end the arms a have depressions b. These depressions afford a means for reaching the binding-screws of a cut-out when attaching wires thereto, and as the depressions in each arm are at opposite sides thereof it is immaterial' from which side the cut-out may be placed in position. A suitable shell or case may be provided for the cut-out within the seat- Having described my invention, what I claim is 1. In an electric-lamp fixture, the combination, with a tubular portion thereof, of a seat for a cut-out, consisting of a frame or ring formed in said tubular portion, having transverse channels to prevent the cut-out from turning and open at the sides, substantially as specified.

2. The combination, with a tubular portion of an electric-lamp fixture, of a seat for a cutout, consisting of outwardly-bent arms having perforations to receive screws and depressions at the ends, substantially as specified.

SIGMUND BERGMANN.
