ILLUMINATED SIGN.

SPECIFICATION forming part of Letters Patent 'N o. 698,256,da.ted. April 22, 1902.

Application filed January 30, 1902. $erial No. 91,898. (No model.)

T0 at whom it may concern;

Be it known that we, GUY D. CHAPMAN and OLOYD R. QUINE, citizens of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented a certain new and useful Improvementin Illuminated Signs, of which the following is a specification.

Our invention has relation to the manufacture of what are known as illuminated electrical signs, and has especial relation to those signs in which the body portion of the letter of which the sign is composed is made from some non-conducting material, such as porcelain, and in which the electrical lamp is partially buried.

The objects of our invention are to produce a new and improved letter in which the means for attaching electric lamps shall be made integral with the main body portion, and it also is one of our objects to so attach the letter to the supporting-frame that it shall at all times be convenient to reach all the wires.

. different figures.

Figure 1 is a front elevation of the letter O with the electric lamps in position. Fig.

2 is a section at the line 00 a: of Fig. 1, and Fig.

vals are holes 3, extending through the main body portion of the letter and nearly to the bottom of sockets 4, which extend from the rear face of the body portion of the letter. These holes 3 are of such a diameter as will admit the socket end of an electric incandescent lamp. In the bottoms of the holes 3 is a central orifice provided with a shoulder and into which is placed a screw 5, provided with a shoulder to encounter the shoulder in the orifice. The upper end of this screw 5 projects into the opening 3 and is designed to mesh with the female threads in the lampsockets and form one of the electric connections of the lamps. Around and substantially concentric with the opening 3 at its bottom is placed a bent ring 6, fastened by two screws 7, which pass through the earthenware bottom of the letter and fasten to a semicircular plate 8 011 the bottom of the socket. The lower end of the screw 5 is threaded and meshes into a contact-plate 9, also on the bottom of the socket 4. On the plates 8 and 9 are screws 10, to which are fastened the wires for the lighting of the lamps, the current passing up from plate 8 by screws 7 to the'ring 6 and thence to the lamp and returning by the screw, 5 and contact-plate 9. These sockets t are made integral with the main body portion of the letter, and the diameter of the base portion of these sockets is larger than where the socket joins the letter and are substantially f in a dovetailed form. The letters are attached to the board 1 by making openings in the board large enough to admit the sockets, and the bodyportion 2 of the letter is brought accurately down on the surface of the board,

and the space around the narrow portion of the socket is filled with some cement, preferably plaster-of-paris, by which means the letter is accurately attached and firmly held in position when the cement dries.

We are aware that advertising-signs made .by attaching rows of incandescent lamps to a board arenot new, and this we do not claim.

What we do claim, and desire'to secure by Letters Patent, is-' 1. The combination in aletter for signs, of a body portion, and depending sockets for the reception of incandescent electric lights made integral with said body portion.

2. The combination ina letter for signs of.
