LIGHT TRANSMITTING BODY Filed June 15, 193s 1N VEN TOR. foei/vf 5mn/mez,
Patented Feb. 26, 1935 LIGHT-TBANSMITTING BODY EugeneSchwarz, Alexandria, `Ind., assignor to The Mantle Lamp Company of America, Chicago, Ill., a corporation of Illinois Application June 15, 1933, Serial No. 675,875
My inventionlrelates to light-transmitting bodies of any kind, and isrespecially applicable ing. This coatingwhich resembles a mist, and,v
optically considered, clouds transmitted light, may be applied to a surface of the sheets in such a manner as to vary the translucency of portions of the sheets to thereby produce ornamental and pleasing designs. Physically, the surface will be of suede-like character.
In the accompanying drawing, Figure 1 is a fragmentary view of a sheet embodying the invention; Q
Figure 2 is an enlarged cross-sectional view taken on the line 2 2 of Figure 1;
Figure 3 is another enlarged cross-sectional view taken on'the line 3-3 of Figure 1;
Figure 4 shows a stencil; and
Figure 5 shows an open-mesh stencil.
In carrying out my invention, as an example,`I apply to a surface of parchment paper 1 a translucent or transparent adhesive 2, suchas, for
instance, varnish or lacquer, and while this adhesive is still in a tacky condition an excess of flock 3 of desired shades, colors or translucency, is dusted thereon. Saidadhesive is then allowed -to dry. The excess ock is then shaken, dusted or sucked away from the surface of the paper. The remaining ock, which adheres to the paper, forms a suede-like coating through which any ornamentation on that surface may be seen. Also, ornamentation may be formed on the suede-like surface.
This adhesive coating may be applied to the entire surface ofthe paper, or to selected areas thereof, to thereby produce desired designs. For this purpose, a stencil 4, which determines the areas to which the adhesive is to be applied, may be employed, or, as an alternative', the adhesive may be printed or sprayed on the parchment paper. A
The stencil 4 may, as shown in Figure 4, be a metal sheet having openings 5 of desired designs through which the adhesive 2 may be laid on the surface of the parchment paper 1, but, preferably, said stencil is an open-mesh silk screen 5a, shown in Figure 5, selected areas 6 of-which are masked by a substance 7 which lcloses the meshes at those areas, so that the adhesive 2 reaches the surface of the parchment paper only through the still open meshes 8 of said silk screen. i
Preferably, the parchment paper 1 is orna- 5 mented with translucent and colored designs before the adhesive 2 and the iiocculent coating 3 are applied, although,- if desired, only uncovered areas 9.0i said paper may later pe thus ornamented, -or said ornamentation may, at the same l()l time be applied to the covered areas.
While it is preferable to apply the ornamentation and the flocculent coating t the same surface of the sheet of parchment paper, satisfactory results may be attained by ornamenting one surl5 face ofsaid sheet, and by applying the occulent coating to the other side thereof, said sheet being so highly translucent that transmitted light renders both the ornamentation and said occulent `coating plainly visible.
The method herein described permits the making of very pleasing ornamental parchment shades of varying translucency. The variation in translucency between the flock-coated and uncoated areas of the shade, greatly accentuates the color Y designs in the uncoated areas and gives a brilliancy to these designs which is notattainable if the shade possesses the same translucency throughout.V
Having `thus described my invention, what I claim is:
1. An ornamented lightgtransmitting sheet of shade material having' a translucent iocculent coating directly and adherently lapplied to a sur-- face thereof `and overlying the ornamentation of said sheet. o Y 2. A light-transmitting sheet having designs on a surface thereof, and a occulent translucent coating overlying said designs.
3. A light-transmitting sheet having designs on a surface thereof, and a translucent occulent coating overlying portions only of said designs.
4. A light-transmitting body having varied designs on portions thereof, and flocculent material overlying certain of saiddesigns only.
5. A light-transmitting body having varied designs on portions' thereof, and flocculent material coinciding with certain of said designs only. ,Y
c. A iight-transmitting sheet inmaterialv having, 5 adherently applied to its surface, a translucent flock coating for clouding desired areas of said sheet. Y
'7. A 'light-transmitting lamp shade having translucent ock as a translucent coating.
8. A translucent lamp shade having trans' lucent ock adherently applied to parts of its surface for varying the translucency of parts of said shade.
9. A light-transmitting lamp shade having adlucent sheets which involves superilcially coating one side of selected areas of a translucent sheet with-a translucentl adhesive, applying 'liock to said adhesive while it is still in a tacky condition, allowing said adhesive to dry, and removing herently applied to its surface a translucent iiock Lexcessive and non-adherent portions of said flock to thereby render the retained ock thin and coating for reducing the translucency of certain areas of said shade and for giving to those areas a suede-like finish.
10. Light-transmitting parchment paper having an adherent translucent coating of flock.
11. Light-transmitting parchment paper having adherently applied to its surface Aa translu cent ock coating for reducing the translucency of certain areas thereof, and for giving to those areas a suede-like finish.
12. The method of producing ornamental translucent sheets which involves supercia1ly` coating a translucent sheet with a translucent adhesive, applying flock to said adhesive while it is still in a tacky condition, allowing said adhesive to dry, and removing excessive and non-adherent portions of said flock to thereby render the retained ock thin and translucent.
13. The method of producing ornamental transtranslucent.
14. The method of producing ornamental translucent sheets which involves superflcially coating a translucent sheet bearing translucent designs, with a translucent adhesive, applying flock to said adhesive while it is still in a tacky condition, allowing said adhesive to dry, and removing excessive and non-adherent portions of said flock to thereby render the retained ock thin and translucent.
15. A light-transmitting sheet of shade material, comprising a transparent sheet of parchment paper, a dried and translucent adhesive adherently attached to said parchment paper, and a thin and translucent layer of flock adherently united to said adhesive.
