SHADE AND SHADE-HOLDER.

SPECIFICATION forming part of Letters Patent No. 503,537, dated August 15, 1893.

Application filed April 28, 1893. Serial No. 472,208. (No model.)

T0 at whom it may concern.-

Be it known that we, HENRY A. C. HELLYER and WILLIAM T. LAWLESS, of the city of Ottawa, in the county of Carleton and Province of Ontario, Dominion of Canada, have jointly invented certain new and useful Improvements in Shades and Shade-Holders for Incandescent Electric Lamps 5 and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part hereof.

Our invention, which will be hereinafter fully set forth and claimed, relates to shades and shadeholders for incandescent electric lamps.

The object of our invention is an inexpensive and more durable shade for incandescent electric lamps, one less liable to fracture and of more protection to the lamp, together with a suitable holder therefor.

Figure 1 is a transverse section of our improved shade and holder, showing a part of the lamp socket in elevation. Fig. 2 is an elevation of the same, corresponding to Fig. 1. Fig. 3 is a top view of the holder without the clamp ring and Fig. 4 shows the separate parts of the holder partly in elevation and partly in section.

A is a shade of stiff paper, cardboard, celluloid or any other flexible material, cut to the required shape and jointed in a sloping line in any convenient manner or molded in one piece and having plain top rim. The interior surface is preferably white and of a reflecting character and the exterior of a darker color, either material of the desired character being used in the construction or the surfaces being suitably finished afterward, but both surfaces may be of any desired color and character. The depth of the shade is preferably made a little larger than the depth, 2'. e., length, of the lamp L, so that the lower rim of the shade projects below the lower point of the lamp, thus forming a protection to the latter in case of the whole of it dropping and striking a hard surface.

The holder consists of three parts: The beveled rim G with flexible neck 0, the beveled ring E to fit the upper rim of the shade and interior bevel of the rim 0 and the clamp ring D to fit the flexible neck c. The rim 0 is made of thin metal and is given the same bevel as the shade, so that the upper rim of the latter will fit the interior of said rim. The neck 0 is formed integrally with said rim by a sloping shoulder c which forms a gradual transition from the larger cone to the smaller cylinder which forms the neck. Said neck fits the lamp socket S and is provided with a bead c to fit the corresponding bead on the socket. Flexibility of the neck is produced by a number of slits, 0", extending all the way through the neck 0 and through part of the shoulder c. This flexibility enables the upper end of the neck 0 to be slipped over the bead on the socket and it is held in place by the clamp ring D, also made cylindric of about the same width as the neck 0 and made with a bead d at the upper edge, and of an inner diameter corresponding to the outer diameter of the bead c" said bead d being partly for appearance and also and more particularly to provide afinger-hold for slipping it on and off the neck 0. The ring E is made about the same width as the rim (J, given the same bevel and slightly smaller in diameter, so as to fit within the rim Q mith the thickness of the material of the shade between them. Both the rim C and ring E are provided with small perforations or slots 0 those in the rim corresponding with those in the ring and through those and the material of the shade between them are passed small paper fasteners F, the ends of which are turned over on the inside of the ring and hold the three together and in place. In Fig. 1 one of these is shown with its points not turned. Any other kind of a fastener would of course serve the same purpose, such as a pin, wire or a screw if the holes in the rim and ring are tapped.

It will be seen that the shade being of cheap material can be manufactured at a low cost and being flexible is not so liable to fracture as glass and the like, that by reason of this it is also a more effective protection to the lamp, that the holder is such as to provide a more effective hold by reason of its beveled rim and the positive hold of the pins passing through the material itself, and that it is much more readily put on or taken 0% the socket if required by means of the flexible neck and clamp ring.

We claim as our invention- 1. In an incandescent lamp shade and holder, the combination of a shade A of flexible material with plainupper rim, the rim 0 havmg the same bevel as the shade and fitting the top thereof and having perforations c and integrally connected by a shoulder a to a cylindric flexible neck 0 provided with head a" and slits c', the clamp ring D having bead d and fitting the head 0 of the neck 0, the bevel ring E fitting the interior of the rim 0 and top of the shade A and provided with perforations c and the fasteners passing through said perforations and the shade, substantially as set forth.

2, In an incandescent lamp shade and holder, the combination of a shade of flexible material with straight upper rim, a metallic rim 0 having the same bevel as the shade and provided with perforations c, flexible neck 0 integrally connected with said rim by a sloping shoulder c and provided with a bead c and slits c, the clamp ring D having bead d at the upper edge and fitting the neck bead c and the fasteners F passing through said perforations 0 substantially as set forth.

3. In an incandescent lampshade-holder,

0 the combination of a beveled rim 0 provided ble by means of a series of slits 0 extending into said shoulder, and a clamp ring D provided with bead d fitting the head a" of the neck, substantially as set forth.

4. In an incandescent lampshade-holder, the combination of a beveled rim 0 having perforations 0 a headed and slit neck a integrally connected with said rim, a beaded clamp ring D and a beveled ring E fitting within the rim 0 and having corresponding perforations, substantially as set forth.

5. In an incandescent lampshade-holder, the combination of a beveled rim 0, a cylindrical neck fitting the lower end of the lamp socket, and a shoulder integrally connecting said neck and rim, substantially as set forth.

In testimony whereof we have signed in the presence of the undersigned witnesses.

HENRY A. C. HELLYER. WILLIAM T. LAWLESS.
