LAMP SHADE AND PROTECTOR.
Specification of Letters Patent.
Patented Sept. 18, 190.
r Application filed January 26,1906. Serial No. 298,032.
. To all whom it may concern:
' canopies, and particularly to electric-light shades, protectors, and canopies of-a reflective character in which the light is reflected both upward and downward, as well aslaterally, and the bulb is. protected against breakage.
It is the object of the invention to provide a shade which shall primarily serve as a protector against breakage to the bulb or globe of the lamp and 'at the same time operate to diffuse light in a most satisfactory manner.
In factories and other places where incandescent lights are used that are generally swung from the end of a wire hanging from above the lights are frequently brought close to the work being done on the. bench, and as a consequence they become very liable to be and are frequently broken, causing in the ag egate great loss and trouble in repairs an rearrangements. It has been essayed to cure these mischiefs and difliculties with greater or less success; but in all cases so ar as we are aware the unsatisfactory condition of things and the defects remain and are not obviated or cured because of failure of inventors to fully grasp the trouble or to meet it with entirely effective means. In very many cases the shades themselves are the source of the injury and trouble, since the cold metal forming a ring and surrounding the bulb without ventilation ofany kind suddenly cools a line or zone around unequal expansion uneven temperature breaks the said line.
the bulb when a shade is placed thereon and where it comes in contact with it, and the and contraction due to globe on the @ur im rovements are an im- 'provement upon this class of lamps and are aimed tocure the defects mentioned. They assuredly do reduce the objections and troubles to a very great extent.
Reference is to be had to the annexed of a cone, one inverted upon the drawings, forming a part of this specification, in which- Figure 1 is a perspective view of the improved shade and protector. Fig. 2 is a vertical sectional view of our improved lamp shade and protector, the bulb being indicated in elevation.
In the drawings, a designates the upper and?) the lower sect-ion of our improved pro,- tecto'r and shade which may be made, say, of bright sheet metal corrugated with alternating sharp ridges and gutters. Each section is constructed in the form of a frustum other and the two connected by a band a. Each section is furthermore. constructed so as to flare outwardly and upward and downward at an angle of thirty to thirty-five degrees, more or less. The band will bemade to encircle the bulb aboutone-third of the way down from its top, and the petticoat or lower section will reach down so as to be even with the lower end of the bulb, while the bodice or upper section'will protect the upper part of .the bulb'in the same Way. T scribed is of great importance, both in point of difl'usion of light and in point of protecting the globe or bulb against injury.
.The bulb or band 0 is provided at brief intervals with flues d on its inner side, through which air passing into. draft-openings e m the outside of the shade below the belt eontinues to rise and passes out of the slits or openings f inside above the belt. The shade is thus ventilated at the band or belt somewhat as indicated by the arrows marked on the drawings, and thus sudden changes in tem erature on the line where the metal ban comes in contact with the glass are" avoided. Beside this, the air passing between the bulb and lower section out between the exterior of the neck and upper section assists in setting into circulation the heated air from the lamp by cooling lamp and shade and protecting the mechanics from heat of lamp.
.While our improvements have not abated all'breakages, it is a fact attested by experience that the form of our improved shade and the ventilation of the belt described have largel reduced breakages and the other troubles mentioned and the form of the shade, as explained, secures an almost he form deperfect diffusion of the light from the lamp. The de recs at which the upper and lower parts 0' the lamp flare outwardly and the extent to which they reach both upward and downward are not essential features of the invention in the service the its lprotectors of the lamp an diflusers of the Inasmuch as the shade rests upon the glass bulb and does not come into contact with metal at the neck of the lamp or other material of a conductive nature, it is a nonconductor, and therefore safe in use on that score. Again, as the shade rests directly over the filament-coil it increases the reflected light two hundred per cent. over the naked bulb or bulb not provided with a shade or reflector in accordance with our invention.
It may be stated that our improved shade is not confined to metal as the substance out of which it may be manufactured, but any material that will erform the functions ascribed to our sha e will answer. Again, the direction in which the upper and lower sections of the shade extends may vary from thirty to thirty-five degrees, the latter figures beln given merely as a line or point from who varlation may extend in opposite Wayst Our improved shade, in addition to posperformboth sessing the advantages mentioned, operates to protect workmen from -the heat radiated from the lamp as usually employed, which is a matter of much importance.
We claim p 1. A shade and protectorfor incandescent lights and bulbs, consisting of two sections of fluted material, made in the form of two conic frusta, one inverted upon. the other and a band provided withyentilatin flues connecting the two, one of said sha e-sections having openings therethrough arranged contiguous to the lower ends of said flues, the
lower section flaring outwardly and reaching to the bottom of the bulb and the upper section flaring outwardly and reaching to the neck of the lamp. 7
2. An incandescent light shade and bulb therefor combined with a belt connecting the sections of which said shade is composed and provided with ventilating-flues, one of said shade-sections havi'ng openings therethrough, contiguous to the lower ends of said flues.
In testimony whereof we afiix our signatures in presence of two witnesses.
