Specification of Letters Patent.

Patented an. 18,1916.

Application filed November 30, 1914. Serial No. 874,911.

To all whom it may concern:

Be it known that I, I-IANs KARL BITTER,

. a citizen of the Republic of Switzerland, and

resident of Niagara Falls, Province of Ontario, Dominion of Canada, have invented following specification and accompanying drawings forming part of the same.

In the drawing, Figure 1 is a sectional elevation of the improved shade. Fig. 2 is .a sectional elevation of a modified form of the same. Fig. 3 is a sectional elevation of another form of shade. Fig. 4 is a top view,

partially sectional, of the binding ring and tension bolt shown in Fig. 3. Fig. 5 is a vertical section of the binding ring and tension bolt shown in Fig. 3. Fig. 6 is a side elevation of a circular light reflector. Fig. 7 is a side elevation of a V-shaped light deflector. Fig. 8 is a plan view, looklng upwardly, of the shade shown in Fig. 1. Fig. 9 is a plan view, looking upwardly, of the shade shown in Fig. 2. Fig. 10 is a fragmentary perspective of the means for securing the annular strips to the frame. Fig. 11 is a fragmentary perspective view of a modified form of a deflecting strip mounted on the frame. Fig. 12 is a fragmentary perspective View of the frame showing the deflecting strips mounted thereon.

Like characters of reference refer to like parts in the several drawings.

Referring to the drawings, M represents the im roved lamp shade comprislng the frame Nsuitably hung by the suspending member S and consisting of a plurality of T-shaped ribs 0 carrying U-shaped brackets or furrows P cast or cut therein. This frame is designed to support the upper reflector A and lower distributer B thereon, and to facilitate in assembling the several parts, the distributer B is constructed of a plurality of slats of rectangular, S or like section of translucent glass or metal D, each of which engages at its end with the U- shaped brackets or furrows P in such a manner that between consecutive strips an air or l1ght space Q, is provided. These strips D are disposed at a suitable predetermined angle to the light source R so that the reflected light rays from the upper reflector A or lower distributer B pass through the spaces Q- which however are so arranged that the light source is not Visible. externally. The upper reflector A comprises an annular member of S, corrugated or like section, or a plurality of such members having air spaces therebetween suitably mounted on the frame N. These members are disposed at a suitable angle to the light source R in such a manner as to facilitate in reflecting the llght rays through the spaces in the refiector and the light spaces Q in the distrptbuter in a manner to be made clear herea er.

It will be understood-that the strips or slats comprisin both the reflector A and the lower distrlbuter B can be made with the outer surface of translucent, white or colored glass, the inner surface of the refiector being matte and the inner surfaceof the distributer highly polished and mirrored, or if it is found desirable the said strips may be made of highly polished metal. In assembling the shade it is only necessary to engage the ends of theseveral slats D of the distributer with the U-shaped furrows P of the frame N when the upper reflector A may be mounted on the said frame.

In Fig. 3 the strips of translucent glass or metal D mounted in the upper portion of the frame N are angularly disposed to those mounted on the lower portion of the frame and are carried inside a clear glass container F, the lower edge of which is offset and engages with the binding ring E suitably secured by means of the tension bolt G. .The reflector A is mounted on a holder H having downwardly disposed air holes I therethrough which are covered by the upper edge of the said holder'and'dex rored surface of the strips D on the outside of the adjacent strip pass outwardly.

In Fig. 2 the rays of-light on the inside section of the reflector A are thrownfback on the outside of the adjacent concentric section 0 and thence upwardl From this description it wi 1 be seen that the proper path is given to the light to effect an even distribution of the same.

a .What I claim as my invention is:

1. A lamp shade of the class described comprisin a frame, a distributer consisting of a plura ity of slats mounted on the frame with spaces therebetween and adapted to prevent the light sourc being seen externally, and an upper reflector consisting of a plurality of annular sections carried by the frame and having spaces therebetween, as and for the purpose specified.

2. A lamp shade of the class described comprising a frame, a distributer consisting of a plurality of angularly disposed slats mounted on the frame with spaces therebetween and adapted to lprevent the light source being seen external and an upper reflector consisting of a'plurality of angularly disposed annular sections carried by the frame with spaces therebetween, the said reflector and distributer being adapted to cause the light rays to pass through the said spaces.

' 3. A. lamp shade of the class described comprising a frame, a distributer consisting of a plurality of slats of S section'mounted on the frame with spaces therebetween, and an upper reflector consisting of a plurality of corrugated annular section shaving spaces therebetween.

4. A lamp shade of the class described comprising a frame, a distributer consisting of a plurality of slats mounted on the frame and having spaces therebetween, the, slats I on the upper part of the frame being angularly disposed to those on the lower part of the frame, and an upper reflector mount: ed on the frame.

5. A lamp shade of the class described comprising -a frame, a lower distributer mounted on the frame consisting of a plurality of slats, and an upper reflector mounted on the frame comprising a plurality of annular sections.

' "6. A lamp shade-of the class described comprising a frame, a lower distributer comprlsmg a plurallty of slats mirrored on the mner side facing the light source and colored on the outer side and having spaces between the consecutive slats, the said slats being adapted to reflect and deflect the light rays through the said spaces.

p A lamp shade of the class described comprising a frame, an upper reflector mounted thereon, a lower distributer. comprising a plurality of slats of translucent glass having air spaces therebetween, the said slats bemgadapted to reflect and deflect light rays from the inner surface to impinge .on the-outer surface of the adjacent slats and thence through the spaces, substantially as described. v

8. A lamp shade of the class described comprising a frame, an upper reflector, a lower distributer comprising a plurality of slats having spaces therebetween, the slats on the upper partof the frame being; angularly disposed to those on the lower part of the frame, and a clear glass contalner surrounding the said distributer.

9. lamp .shadeof the class described comprising a frame, a distributer mounted on the frame, an upper reflector comprising a plurality of annular sections carried by the frame and having spaces therebetween, the

said annular sectlons'being designed to reflect the light rays from the inner surfaces to impinge on the outer surface of the ad-- j acent section and thence through the spaces, substantially as described.

10. A lamp shade of the clas described comprising a frame inclosing a light source and consisting of a plurality of T-shaped ribs having U-shaped furrows therein, lower deflecting members mounted on the said frame comprising a plurality of reflecting sections engaging with the 'U-shaped furrows, and an upper reflector mounted on the frame comprising a plurality of annular sec-.

tions, substantially as described.

In witness whereof I have hereunto set my hand in the presence of tWo Witnesses. 1 HANS K. BITTER.
