VVALLAOE II. WELLS, OF BRASHER'FALLS, NEV YORK.
lNCANDESCENT-LAMP SHADE OR COVER.
SPECIFICATION forming part of Letters Patent No. 609,924, dated August 30, 1898.
A licatio filed March 28, 1898. Serial No. 675,514. (No model.)
To all whom it may concern:
Be it known that I, WALLACE H. WELLS, a citizen of the United States, residing at Brasher Falls, in the county of St. Lawrence and State of New York, have invented certain new and useful Improvements in Incandescent-Lamp Shades or Covers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to an improvement in incandescent-lamp covers or shades; and its object is to provide a cover, simple and economic in construction, which is capable of being easily attached or removed from the bulb of the lamp, thereby permitting the ready use of diiferent-colored covers-a feature most desirable for display purposes and for use in hospitals, &c.
The device is exceedingly simple in construction, consisting, as it does, of a narrow strip of spring metal adapted to clamp the upper end of the bulb between itsends. To the outer sides of this strip is attached a suitable transparent material adapted to incase the bulb and capable of changing the color of the light-rays passing therethrough.
In the accompanying drawings, which show the preferred form of.my invention,Figure 1 is a perspective view showing my improved cover applied to a lamp. Fig. 2 is a vertical longitudinal section through the cover and the strip therein, and Fig. 3 is a cross-section.
Referring to said figures by letters of reference, A is a narrow strip of spring metal forming a loop adapted to be sprung over the lamp-bulb, grasping the upper part of the same between its outwardly-projecting ends ct a, as shown. Secured to the outer fiat side of the strip A at any desired points thereon is a suitable material B, capable of changing the color of light-rays passing therethrough. If desired, however, said cover B may be made detachable from the strip by providing perforations through the spring and cover through which a suitable fastening device I) is passed. It will be obvious that this latter construction is preferable, as it provides for the use of separate covers with but one spring.
the lamp, While its slight cost and simplicity of construction make the same most desirable for use.
While the cover B may be of any suitable material, I prefer the use of crimped or crape paper owing to its slight cost and the readiness with which it adapts itself to the contour of the lamp-bulb.
In the foregoing description I have described the preferred form of my invention; but I do not limit myself thereto, as I am aware that modifications thereof can be made without departing from the spirit or sacrificing the advantages thereof, and I therefore reserve the right to make such changes as fairly fall within the scope of my invention.
Having thus described my invention, what I therefore claim as new, and desire to secure by Letters Patent thereon, is-
1. As a new article of manufacture, a shade for incandescent lamps consisting of a springmetal strip the ends of which are adapted to clasp said lamp, and a cover secured to said strip and adapted to incase the lamp-bulb, substantially as described.
2. As a new article of manufacture, a shade for incandescent lamps consisting of a narrow spring-metal strip adapted to loop over the bulb and having outwardly-projecting ends for clasping the upper end of said bulb therebetween, and a cover or shade secured, substantially as described, to said strip and adapted to incase the bulb, substantially as and for the purpose described.
In testimony whereof I aifix my signature in presence of two witnesses.
