IMPROVEMENT IN LAMP-sHADEs.

v Specification forming part of Letters Patent No. 131,173, dated September 10, 1872.

To all whom 'it may concern:

Beit known that I, GEORGE MAGBEIDE, of Carthage, in the county of Hancock and State of Illinois, have invented a new and useful Improvement in Lamp-Shades; andI do here-- by declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawing making' a part of this specification, in which- Figure l is a view, showing the shade set in position. Fig. 2 is a perspective View, showing the frame ofthe shade.

VLike letters in both iigures ot the drawing indicate like parts.

'.Lhe object ol' my invention is to protect the human eyesight from the glaring rays of the lamp or gaslight; and the invention relates to a shade having its shape made somewhat similar to that of ak cylinder, but representing more precisely the form of a frustum of a cone; the said shade consisting of bleached muslin or light-colored cottoncloth, bound at either end with tin or other suitable metal,and kept 1n position, longitudinally, by metallic standards connecting suitably with the metallic binding on the edges orends of the cloth, as above referred to; the device resting upon the body ofthe lamp, below the burner, and occupying a position just outside of the chimney, Irom which it is protected by projections from the metallic binding 5 the size of the shade being made to suit the various lamps in use.

To describe my invention more particularly attention is called to the letters of reference designating the various parts of its construction, as follows: A represents the top of the lamp; B, the shade proper; O, the burner; D,the chimney; E, the metallic rim or binding at the base of the shade, as hereinbefore mentioned; and F, the metallic rim or binding at the top; G, the metallic standards attached in any suitger-pieoes on the outside of the shade, near itsA base, for convenience in handling.

The ordinary construction of the shade is essentially as I have now described it but it yis evident that in manifold ways changes ma-y be made in the mere detail of the manufacture without in any sense departing from the invention now described and illustrated.

My improved shade will operate successfullyover any ordinary lamp having a chimney with few irregularities and a form approach` ing that of acylinder. It will protect the eyes completelywithout straining them. rlhe human eyes are injured bythe presence of a nude or reiiected flame of re, but this subdues its brightness without sacrificing necessary light, as a mild shade in summer protects us from the dazzling rays of the sun without depriving us of the convenience of the day. It is of a convenient shape; others, hanging from the top of the chimney,\protect the eyes only in certain positions, and they must be laid aside when the lamp is not in use, or on the shelf, thus rendering them liable to be broken or injured, While the place for this shade is on the lamp.

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

The lamp-shade herein described, consisting of the metallic rims E F, standards G, anges a a., and cloth B, the whole constructed substantially as and for the purpose set forth.

GEORGE MAOBRIDE.
