REFLECTOR. I

Specification of Letters Patent.

Application filed October 7, 1905' Serial No. 281,776.

To all whom it may concern:

Be it known that I, ZEELIG MA'rLowsKY, a citizen of the United States, and a resident of the city of- New York, borou h of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Reflector, of which the following is a full, clear, and exact description.

This invention relates to reflectors made of glassware or porcelain and used with lights or lamps; and the object of theinvention is to produce an improved form for the surface of such parts as will benefit their reflecting qualities.

The invention consists in the construction and combination of parts to be described 2 is. a cross-section showing a portion of the.

- wall of a globe and illustrating clearly a form which its surface may take; and Fig. 3 is a view similar to Fig. 2, but representing a different construction of the surface of the globe.

Referring more particularly to the parts, 1 represents a lamp-globe, which may have a su stantially sphericaL'body 2 and a reduced neck 3 therebelow, as shown. It should be understood that in pra fee the source of illumination will be located substantially the center of the body 2; 'In forming a globe according to my invention I provide its surface with a plurality of cavities 12 of substantially pyramidal form, the same preferably being arran ed in horizontal and vertical rows, as in icated. I prefer to form these cavities 12 on the outer sidegof the lobe, so that pyramidal projections 12 are fbrmed on the inner side, as indicated in Fig. 2. These cavities are arranged in horizontal and vertical rows, presenting sharp edges 13 on the outer side between the cavities. The inclined faces 14 of the cavities do not meet .however, is the same as be ore.

below, butare connected by flat surfaces 10. On the inner face of the globe recesses 16 are formed which are in alinem'ent with the edges 13, said recesses presenting inclined clined aces are reflected through the trans- I lucent surfaces 10. In this way the light coming from the illuminated point is diffused, so that the entire globe appears to be a low.

In ractice the cavities 12 are so smaIl relative to the size of the lobe that the effect is pro need of myriads 0 illuminated points.

Instead of forming the cavities on the outer side of the globe, as indicated at 4 in Fig. 2,1 may form them on the inside, as indicated in Fig. 3. The principle applying in this case,

Referring to this figure, the cavities 4 are formed with substantially flat bottoms 7. A reflecting-coating 8 is applied to the inclined side faces 5 of the cavities, but is not applied to the surface 7. With this form the inclined faces 5 meet i in sharp edges 6 on the inner side-ofthe globe,

as shown.

While I have described the invention as applied to a globe and refer that the globe shall be constructed 0 glass, in ractice I may make the reflecting body 0 anyform desired. Thus I may form the surfaces on chimneys in the manner described above.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A reflector ada ted to surround an illuminated point-an having upon its surface a plurality of cavities presenting inclined faces coated with a reflecting substance, said cavities having uncoated bottoms through which the reflected light may pass.

2. A reflector having in its surface a plurality of cavitiesformed in rows and presenting substantially flat surfaces at their bottoms, with inclined side faces, said inclined 5 faces having a coat of a reflecting substance adapted to reflect light through said bottom faces.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
