Specification of Letters Patent.

Patented Dec. 2s, 1909.

Application led March 8, 1909. Serialy No. 481,903.

To all whom 'it lmay concern.'

Be it. known that I, CHARLES T. SCHRA- DER, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of 'Missouri, have invent-ed certain new and useful Improvements in Lamp- Globes; and I do declare the following to be a full, clear,'and exact description of the invention, such as will enable others skilled. p

in the art to vvwhich it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of'this specification.

My invention relates to a lamp globe and has for its object to provide a device of that class by whichrays vof light maybe magnified when passing therethrough. In accomplishing this object, I provide a lobe body having bulbular projections, or ulls eyes, on its outer face and pyramidal or other shaped points projecting from the globe body between the impinging points of adjacent bulls eyes. The preferred form of my improved globe is illustrated in the accompanying drawings, 1n whichz- Figure I is a side View of a globe con- II is a horizontal sectional View of same 'on the line IIe-II, fFig. I. Fig. III is a Vertical sectional view on the line III-III, Fig. I. Fig. IV is an enlar ed detail view 0f portions of adjoining bul s eyes and the points located in the spaces therebetween.

1g. V is a vertical sectional View of a slightly modified form of lobe.

Referring more in detai to the parts l designates the globe body which may be `formed in a -mold to rovide a smooth inner surface with the bul s eyes, 2, formed integral with the body and projectin from the outer surface thereof, the bull sf'jeyes being arranged in rows on the' Surfacezif- Fig.

the globe and the adjoining rows being staggered in order that the bulls. eyes may set closely together and cover, as nearly as possible, the entire outer surface of the globe.

In arranging the bulls eyes in the man* ner described, substantially triangular portions of the globe body Would remain exlosed and form crevices-`tl1at would interfere with thefproper diifusion of li ht. In order to obviate such imperfect di usion, I form pyramidal or other sha ed members in the spaces between the adjoining bulls eyes,'the sides of which taper outwardl to a common point and serve to diliuse llght thrown thereon by the rounded 'surfaces of the bulls eyes.

With a globe of this construction the rays of light passing through each of'the bul eyes `is magnified and rays-thrown against the points arevdi used therefrom to increase the efficiency of the globe and obviate shadowing of one bulls eye by another.

I prefer that the bulls eyes be substantially hemispherical in form, so as to present avery artistic a pearance.

Having thus descri m invention, what I claim' as new therein an desire to secure by Letters-Patent is l i A glass globe for lights, having its outer surface formed into numerous contacting hemispherical .protuberances, arranged in staggering relation, and also rovided in `the trian lar spaces between said protuberances with pyramidal points adapted to diffuse 'the light refracted by the protuberances; substantially as described.

In testimony whereof I aliix my signature in presence of two witnesses.
