JOHN G. NORRIS, OF DENVER, COLORADO.

LAMP SHADE OR REFLECTOR.

To all whom it may concern:

Be it known that I, JOHN C. Norms, a citizen of the United States, residing in the city and county of Denver and State of Colorado, have invented certain new and use ful Improvements in Lamp Shades or Beflectors; and I do declare the following to be a full, clear, and exact description of the in vention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in shades or reflectors for lamps and while more especially adapted for use in connection with electric lamps, its use of course is not limited thereto but it may be employed wherever a device of this general character is required.

My improved lamp shade or reflector consists of a device having a perforated central portion from which extend a number of radially disposed parts consisting of two sets occupying different inclined planes, the upper and" lower parts alternating with each other and forming partial sectors of a circle, the central portions of the sectors, however, being interrupted by the central perforation. The lower sides of these radially disposed parts are provided with reflecting surfaces. The two sets of parts are connected by radially disposed parts forming angles with the first named parts. As shown in the drawing these connecting parts form right angles with the two sets of connected parts. The exact angle of the said connecting parts, however, is not essential and may be varied. These connecting parts are formed of transparent material, whereby a portion of the light from the lamp or other illuminating device is allowed to pass through, thus giving a considerable degree of illumination above the shade or reflector, thereby distinguishing my improved construction from a perfect reflector or a device which reflects all of the illuminating rays.

Having briefly outlined my improved construction, I will proceed to describe the same in detail reference being made to the accompanying drawing in which is illustrated an embodiment thereof.

Specification of Letters Patent.

Application filed April 29, 1907.

Patented Oct. 20, 1908.

Serial No. 370,919.

In this drawing, Figure 1 is a top plan view of my improved device. Fig. 2 is a perspective side View of the same. Fig. 3 is a sectional detail view.

The same reference characters indicate the same parts in all the views.

Let the numeral 5 desi nate the central portion of my improved device having the perforation 6. From the part 5 lead two sets of radially disposed parts designated 7 and 8, respectively. These parts 7 and 8 are alternately arranged, the parts 7 being at a greater elevation than the parts 8. These two sets of parts are connected by triangular parts 9 forming suitable angles with the parts 7 and 8. These parts 9 are also radially disposed and as shown in the drawing form right angles with the parts 7 and 8. The parts 7 and S if formed of glass or other transparent material, are coated on their upper surfaces whereby their lower surfaces constitute reflectors.- This coating is designated Q in Fig. 3. This figure also shows that the angle parts 9 are transparent and non-reflecting, whereby the light from the illuminating device is allowed to pass freely therethrough, thus giving a considerable degree of illumination to surrounding objects as heretofore explained.

Having thus described my invention, what I claim is:

1. A lamp shade or reflector comprising a central perforated portion from which lead radially disposed parts arranged at different elevations, and parts arranged at suitable angles and connecting the radially disposed parts, the said connecting parts being transparent while the lower surfaces of the connected parts constitute reflectors, substantially as described.

2. In an improved article of manufacture, a shade or reflector having a central portion from which lead two sets of radially disposed inclined segmental sectors arranged at different elevations, and transparent parts arranged at suitable angles and connecting the two sets of sectors, the two sets of connected parts forming reflectors, for the purpose set forth.

3. A lamp shade or reflector comprising a central portion from which lead two sets of radially disposed inclined parts arranged at different elevations and alternating with each other, and transparent parts arranged at the two sets of parts to permit the light 10 suitable angles and connecting the two sets from the illuminating device to pass freely of parts, for the purpose set forth. between said parts, for the purpose set forth.

L. A lamp shade or reflector comprising a In testimony whereof I affix my signature 5' central portion from which lead two sets of in presence of two witnesses.

radially disposed inclined parts arranged at JOHN C. NORRIS.

difierent elevations and alternating with lVitnesses: each other,- the lower surface of the said parts DENA NELSON, forming reflectors, and means for connecting MAY GAWLEY.
