SHADE FOR INCANDESCENT LAMPS.

Specification of Letters Patent.

Patented Jan. 28, 1908.

Application filed August 27, 1906. Serial No. 332.254.

T 0 all whom it may concern:

Be it known that I, EDWARD B. LEwrs, a citizen of the United States, residing at Pacific Grove, county of Monterey, and State of California, have invented certain 'new and useful Improvements in Shades for Incandescent Lamps, of which the following is a specification.

My invention relates to shades for incandescent lamps.

In the present invention my object is to provide, first, a novel shade-holder of simple and inexpensive construction, which can be quickly and easily applied to or removed amp socket and, second, a novel shade of artistic appearance having a new and original construction both in regard to the shade itself and its manner of attachment to the shade-holder, whereby the shade, being in a plurality of separate parts, may be readily assembled with the shadeholder and, if one of the shade parts becomes damaged or broken, it can be removed and replaced by another without disturbing the remaining portions or parts of the shade, beside which my improved construction has the advantage of being less liable to breakage than it would be were the shade made in one rigid piece.

In addition to the foregoing objects, the invention contemplates the provision of a shade, particularly adapted for use with incandescent lamps, the construction of which permits the employment of ieces of shell, thereby obtaining beautiful lighting effects by reason of the natural colors of the shell.

The invention is set forth fully hereinafter.

In the accompanying drawings :Figure 1 is a perspective of the invention; Fig. 2, a plan view showing the shade-holder in section just above the clamping band; and Fig. 3, a detail section through a portion of the shade and throu h the shade-holder, showing the detachable astenings which secure the parts of the shade to the points of the shadeholder.

In Fig. 1, dotted lines represent an incandescent lamp, its socket, and its conductor cord.

The numeral 1 represents the shell of the shadeholder, said shell having an inwardly turned upper edge 5 and being provided with a slot 10 in its side, while its lower portion is formed in a single piece with downwardly extending outwardly projecting independent points 2 which are of ornamental configuration.

The shade is composed of a plurality of pieces or members 8, which are secured to the points 2 by detachable nuts and bolts or rivets 4, said shade members 3 overla ping each other in the manner shown most 0 early in Fig. 2, which is accomplished by having the points or prongs 2 slightly tilted sidewise. The shade sections 3 may be of any desired material, but I preferably employ shell for this purpose as it is more or less transparent and beautiful color effects are obtained by the passage of the light from the incandescent lamp therethrough. Among shell which can be obtained cheaply, is the abalone which exists in great quantities alon the Pacific coast.

WIthin the shade-holder 1 and secured thereto by a single rivet 7 is a clamping band 6 of springy material which tends to expand. The rivet 7 is located intermediate the ends of the clamping band 6 and the ends 8 and 9 of the band are bent and extended through the slot 10 in parallel relation and through them passes a tightening or adjusting screw 11 which is screw-threaded into the end or ear 9 and passes loosely through the end or ear 8. On account of the freedom of the clamping band 6 at all points except where secured by the rivet 7, the clamping band is particularly Well adapted to pro erly conform to the lamp socket and can e quickly and easily tightened or loosened, while the overhanging edge 5 protects the band 6 and makes a snug and finished fit with the socket of the lamp.

The employment of a plurality of points or rongs 2, forming part of the shade-holder, with detachable connections to the shade, has the advantage of enabling the shade to be securely attached in a removable fashion without employing excess metal, aside from the ornamental appearance which is obtained and the fact that the separate parts of the shade can be independently detached so that if one part becomes broken, it may be readily replaced at relatively small expense and the necessity for substituting a complete shade is obviated. 7

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a shade-holder, the combination with a shell having a plurality of flat divergent laterally extending shade attaching parts each formed as one piece andrigidly attached thereto Whose planes lie in general transverse relation to the longitudinal axis of the shell, of a shade rigidly connected directly to the said shade attaching parts.

2. vThe combination With a shade-holder having a shell provided with apluralityof shade attaching members constituting eX- tensions of one of the edges or margins of said shell and extending in a general transverse relation to the longitudinal aXis of said shell, of a plurality of independent shade sections rigidly attached to the respective members aforesaid. 1 8. The combination with a shade-holder 1 having a shell provided With a plurality of shade attaching members constituting eX- tensions of one of the edges or margins of said shell and collectively flared outwardly from said shade-holder in general transverse relation to the longitudinal axis of said shell, of a plurality of independent shade sections rigidly attached directly to the respective members aforesaid.

In testimony whereof, I hereunto afliX my signature in presence of tWo Witnesses.
