UNITED STATES PATENT OFFICE.

JOHN K. RIDDLE, OF TOLEDO, OHIO, ASSIGNOR TO THE EDWARD N. RIDDLE COMPANY, OF TOLEDO, OHIO, A CORPORATION OF OHIO.

LIGHTING FIXTURE.

Application filed December 17, 1923.

To all whom it may concern:

Be it known that I, JOHN K. RIDDLE, a citizen of the United States, residin at T0- ledo, in the county of Lucas and gtate of Ohio, have invented a certain new and useful Improvement in Lighting Fixtures, of which the following is the specification.

My invention relates principally to that class of lighting fixtures which are provided with arms which carry an electric light at their extremity.

In devices of this kind, it is usually customary to separate the electric light socket from the arm and this socket has to be provided with an ornamental socket cover or,

an ornamental husk-in some instances both.

My invention has for its object to provide aconstruction in which the termination of the arm of the fixture itself may be utilized to provide an ornamental covering for the socket and at the same time to provide a construction which will permit the shell of the socket to be rigidly secured to the fixture so that it is entirely concealed from View, thus effectively dispensing with the necessity of providing either a socket cover or a husk, and to accomplish the same in such a way that no skilled labor will be required in erecting the fixture, as is the case where the usual construction is followed.

My means of accomplishing the foregoing objects are readily seen in the accompanying drawing which is hereunto annexed and is a part of this specification.

Fig. 1 is a side elevation of a fragmentary portion of an arm for a chandelier, the ex tremity being shown in section for the purpose of disclosing the construction of my improvement.

Fig. 2 is a top of plan view of the arm.

Fig. 3 is an enlarged fragmentary de tailed view showing the means of attaching the shell to the fixture part.

The same reference numerals refer to similar parts throughout the entire description.

As shown in the drawing, the lighting fixture is provided with an arm 1 which is usually cast and at its extremity is formed, as shown in the drawing, into a cylindrical member 2. Although this member is shown and described as cylindrical, it will be obvious to persons skilled in the art that it does Serial No. 681,214.

not have to be cylindrical in its exterior or cylindrical in its vertical proportions, as it may be flared or it may be polygonal on its exterior and still be capable of being employed in identifying my invention.

Within this cylindrical member 2 is mounted the shell 3 of a standard electric lamp socket, the exterior wall of which being of a size to abut against the interior wall of the cast cylindrial member. When this shell is mounted in this position, an expansible swage is placed inside of the shell, the swage being provided with a plurality of outwardly projecting pointed arms so that when it is expanded, the points of these arms impinge upon the brass socket shell and swage it into the metal, forming the cylindrical member as at l, with the result that it becomes securely and firmly attached to the cylindrical member in such a manner that it possesses great rigidity. The remaining parts of the socket may then be inserted in the shell, and the cap 5, through which the electric conductors pass, is placed at its upper end which is ordinarily crimped, as at 6, to hold the cap on it.

The cylindrical shell 2 has a shoulder 7 formed on the inside thereof. The usual shoulder 8 found on socket shells fits against this shoulder and helps the lugs 9, pressed out of the shell 3 into shell 2, in securing these parts together.

Having described my invention, what 1 claim as new and desire to secure by Letters Patent of the United States is:

1. As an article of manufacture a fixture arm having an open ended shell, a shoulder within the shell, a light socket within the shell, said socket having a shoulder between its ends resting on the first mentioned shoulder, and lugs on the socket shell pressed into the open ended shell for securing the parts together.

, 2. A lighting fixture arm having an open ended cast integral shell, a socket shell within said shell and integral lugs on the socket shell pressed outwardly into the metal of the cast shell, and a cap for closing both shells.

Dated November 23, 1923.

JOHN K. RIDDLE.
