SHADE OR REFLECTOR.

Patented Jan. in, 1911.

Application filed February 12, 1910. $e1ia1 .No. 543,323.

To all wiwm it may concern:

and render the reflected rays less strong and penetrating.

A further object is to provide a glass shade or reflector wherein the reflecting.

prisms have outer plain facets, giving said prisms a truncated form adapted for permitting the passage of light rays in radial directions. rind a still further object is to provide a reflector having outer facets on the reflecting prisms, adapting it for trans mitting, a Well as for reflecting, light, and having on said facets bead-like projections each of which is adapted for concentrating iight rays at a point outside'the reflector, said projections consequently giving to the reflector a highly ornamental appearance.

in describing the invention in detail, reference is had to the accompanying drawing, forming a part of this specification, in which Figure l'is a side elevatibn of a shade or reflector embodying my invention; F ig. 2 is a vertical section on the line 22, Fig. 1; and Fig. 3 is a horizontal section on the line 33, Fig. 2.

Referring to said drawing, in which like designating characters distinguish like parts throughout the several views-1' indicates the body of the glass shade or reflector, which may be of any preferred form and which is i'urrowed on its exterior with V-shapcd substantially parallel grooves 2, 't'orming prisms Be it known that I, GEORGE L. KRAATZ, a l

jections 5, l

3 of truncated shape between adjacent grooves, each prism terminating in a longitudinal facet 4, parallel to its base, instead of in the usual edge.

Formed on the facets 4 and spaced apart In any preferred manner are bead-like proeach of which constitutes an extremely small plano-eonvex lens of a bullseye type adapted for concentrating light rays. As is obvious, the facets i permit the transmission of light rays which would otherwise, were complete prisms employed, be reflected; and the employment of a large number of the bead-like, or lens-like, proections 5, while ornamenting the shade or reflector, serves to concentratev some of the light rays and to so direct them that a soft, diffused and,'at the same time, strong light will be directed radially.

Having thus described my invention, what I claim .as new, and desire to secure by Letters Patent, isv 1, A glass reflector having its exterior face fHIIOWBd with substantially parallel V-shaped grooves which are separated so as to leave longitudinal plain surtacestherebetween, and bead-like projections formed on said plain surfaces.

2. A glass reflector having its exterior surface tun-owed with substantially parallel ii-shaped grooves, prism-like ribs occupying the spaces between adjacent grooves, said ribs terminating in outer lon itudinal facets, and bead-like projections ormed on said facet-s. i

3. A glass reflector of the prismatic type wherein the prisms terminate in plain narrow facets which lie parallel to their bases, and plane-convex lens-like project-ions formed on said facets.

In testimony whereof I aflix my signature ll. 16. DUNLAP, liuugn Monms.
