REFLECTOR.

Application filed February 5, 1916.

To all whom it may concern:

Be it known that I, HENRY DOLIER, Jr., a citizen of the United States, residing at Bridgeport, county of Fairfield, State of Connecticut, have invented an Improvement in Reflectors, of which the following is a specification.

This invention relates to the manufacture of two-part reflectors, that is, reflectors comprising a body portion having an initially separate extension or neck portion secured thereto, and has for its object the provision of a simple, durable and inexpensive means of attaching the body portions and extensions together, so that the neck portion or extensions and different styles of body portions of the reflectors may be kept in stock and special orders for different styles may be assembled from the stock, thus rendering it unnecessary to keep the various styles of Originally, electric light reflectors were attached directly to the lamp sockets. Later, the requirements of use developed the need of extensions to the reflectors, and reflector and extension were secured together by a lap joint. This did not prove satisfactory, however, especially when the parts were of steel finished with a porcelain enamel. It was next attempted to make the body and neck portions of the reflector in one piece, but the expense proved prohibitive, owing to the number of defective pieces. Other modes of manufacture have been to make the reflector and extension of steel and weld them together, and to make'the reflector of steel and the extension of copper and secure them together by a lap joint. Neither of these modes of manufacture meets the present requirements in a satisfactory manner.

My present invention consists in making both the body portion of the reflector and the neck portion or extension of steel which may receive any required finish, ordinarily porcelain enamel, and in securing the parts together by means of a soft metal gasket.

In the accompanying drawing forming a part of this specification, Figure 1 is a sectional view showing reflector, gasket and extension disassembled; Fig. 2 a similar view showing the parts assembled; Fig. 3 a sectional view on an enlarged scale showing the manner in which the edges of the gasket are closed about the flanges on the flector and ex ension respectivel Fig. 4

a perspective view of the gasket as formed and kept in stock ready for use; Figs. 5, 6 and 7 elevations showing extensions assembled with different styles of stock reflectors, and Fig. 8 is a view similar to Fig. 3 showing a slightly variant form especially adapted for use in connection with heavy reflectors.

10 denotes the body portion of a reflector ordinarily, but not necessarily, made of steel. The term reflector, as used, is intended to include shades as a matter of course, it being obvious that the special configuration or design of the reflector or shade or the material of which it is made, are not of the essence of the invention.

11 denotes the neck portion or extension,

preferably but not necessarily made of steel,

and ordinarily of a standard design, substantially as indicated in the drawing.

The reflector is provided with the usual central opening surrounded by an inwardly extending flange 12. The neck portion or extension is tubular and preferably its general configuration is that of a truncated cone. At the lower or meeting edge of the neck portion or extension is an outwardly turned flange 13, the contiguous faces of the tWo flanges overlapping.

14 denotes the gasket which may be made of any soft metal or alloy but is ordinarily made of copper, and is broadly ring-shaped, the ends, however, remaining unattached. The gaskets are produced from a strip of 'metal and are formed to the required shape by rolls, and cut into pieces of the required length. The form of the gaskets as kept in stock is clearlv shown in Fig. 4, one-half of the width of the ring being left flat, as indicated at 15, and the other half having rolled therein an internal circumferential groove 16 to receive the outwardly extending flange of the extension. In assembling, the gasket is sprung over the flange 13 of the neck portion or extension, which lies in the groove, then the flat portion 15 of the gasket is passed through the opening in the body portion of the reflector, and then the other edge of the gasket is closed outwardly about the inwardly extending flange 12 of said body portion, as clearly shown in Figs. 3 and 8. The cross section of the gasket in the assembled position is substantially that of the letter 8, one edge of the gasket being closed inwardly about the flange of the neck pop tion or extension, and the other edge being closed outwardly about the flange of the body portion of the reflector, thus holding the body and neck portions rigidly and firmly together and providing a means of connection that will fully meet the various requirements of use and will be durable, as the gasket, when made of copper, will not oxidize under the ordinary conditions of use.

It is of course immaterial whether the flange of the extension lies above the flange of the reflector, as in Fig. 3, or below it, as in Fig. 8. In one instance the flat portion of the gasket is passed downward through the opening in the reflector and in the other instance ,it is passed upward. The form illustrated in Fig. 8 is preferable for heavy reflectors, as the weight of the reflector is carried by the extension instead of being entirely upon the gasket.

Having thus described my invention, I claim:

1. A two-part reflector comprising a flaring body portion and a neck portion, said portions being provided with oppositely diwithin which said flanges are clamped. V V

, 2. A two-part reflector comprismg a flaring body portion and a neck 'portiomsaid body portion being provided with an inwardly directed flange and said neck portion with an outwardly directed flange at the adjoining edges of said portions, and an annu lar connecting gasket having oppositely disposed circumferential grooves within which said flanges are clamped.

3. A gasket for the purpose set forth comprising a ring of soft metal having its ends unattached, said ring having a flat body provided with an outward bend at approximately the median line, the edge of the bent portion being extended inwardly and spaced from the outwardly bent portion to form an internal flange receiving groove.

In testimony whereof I aflix my signature.
