' SCREEN'.

To all 'whom it 'may concern:

Be it known that I, CLYDE J COLEMAN, a citizen. of the United States, and a resident of New'York, county of New York, and State'of New'- York, have invented certain new and useful Improvements lin Screens,

" ofwhich the following is avspecification.

'My invention relates to screens, and more particularly to screens upon which moving pictures' and stereopticon views are pro- ]ected.

One object of my invention is to provide "'ajsoreen' 'which-the `iljluanimatien effect or ,f camouhtovf light isgreatlyincreased, so that vivid, and yet atthe same time the screen may be cheaply 4and easily made and isflexible, 'so lthat it may be conveniently lcarried v from place to placeand easily put up, Furtherobjects, l eatures 'and advanta es .will

It is transmitted V,through the coating 3, and striking against the silver coating or reiecting surface '2 Ais refiected back, and increases the degreev ofl illumination of the surface 4. 11am'. aware that ithas been suggested `to vuse a. ground glassw'ith a reflecting back, but my' arrangement has distinct advantages over s'uch a screen since my improved screen is iexible, thus enabling it to be more easily put .up and carried fromplace to place, as well asu being vfar less ,expensive to manufacture, especially when the screens are of considerable size, And' furthermore, my improved screen has' a further distinct advanta e in that the coating 3 is comparatively thm so that the rays offlight are refiected at a point very Anear the surface 4,4 and thus .-lthos'e rayswhich passl l.through the `coating 'v dat, an angle thereto are reflected back-sub# f s'tantiallyjtozfthe same poi'ntiat-Which they zstrike'pthe surface 4.

2. A screen of the class described, coniprising a flexible bod portion having a coating on one sidea apted 'to form areecting surface on that side and a. partiell 10 opaque coating over the first coating, bot

of said coatings being on the same side of the body portion.

In testlmony whereof, I have signed my, name to this specification, in the presence of two subscribing witnesses.
