MOVING-PICTURE SCREEN.

Specification of Letters Patent.

Patented Dec. 23, 1913.

Application filed August 29, 1-312. Serial No. 717,813.

To all whom it may concern:

Be it known that I, SAMUEL H. Jonas, a citizen of the United States, residing at Altus, in the county of Jackson and State of Oklahoma, have invented certain new and useful Improvements in Moving-Picture Screens; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in methods of producing a screen for receiving pictures thrown thereon from stereopticons or moving picture machines.

One object of the invention is to provide a method of producing a screen of this character the picture receiving surface of which is constructed in such manner that the pictures thrown thereon will be much more distinctly shown and all the details of the picture clearly brought out.

Another object is to provide a method of producing a screen upon which pictures may be exhibited and clearly seen in the daylight or without darkening the room in which the pictures are being exhibited.

A further object is to provide a screen of this character which may be readily rolled without danger of cracking the picture receiving surface thereof.

In the accompanying drawings Figure l is a perspective view of a portion of a screen produced by this method; Fig. 2 is an en larged sectional view of a portion of the screen showing the first step in the construction of the same; Fig. 3 is a similar view through a portion of the completed screen.

In the construction of my improved screen according to this method or process I employ a base or body 1 of suitable fabric woven or otherwise constructed. For the body or base of the screen I preferably employ common table oil cloth to which is applied the coating for forming my improved screen. Before applying the coating the oiled surface of the cloth is first preferably softened by applying thereto a solution of oil. The cloth after having the oil applied thereto is allowed to stand for twenty-four hours more or less. When thus treated the oil cloth becomes extremely soft and pliable and forms a much more satisfactory base upon which my improved coating is applied.

After the oil cloth has been softened in the manner described I apply a coating 2 of J ap-a-lac or other suitable form of varnish with which has been mixed a proper amount of turpentine. \Vhen this mixture has been applied the curtain is permitted to stand for four hours more or less or until this coating is about two-thirds dry. When the coating is thus partly dry, powdered aluminum 3 is thickly sprinkled over the surface and rubbed in with. a woolen brush or other suitable implement until the powder is thoroughly set in the J ap-a-lac and turpentine coating. The first application of the oil to the oil cloth base strikes through and softens the same and imparts to the finished screen an oily velvet effect.

It has been found after experimenting that a screen properly constructed in accord ance with my invention forms a background which produces a soft effect to the picture thrown thereon at the same time bringing out clearly and distinctly every detail of the picture. The softening effect produced by my improved screen does not tire or affeet the eyes as does the usual form of screen. The picture may also be produced on the screen with much less light than is necessary in the usual exhibition of storeopticon or moving pictures and by the use of my improved screen, pictures may be thrown and clearly seen thereon in daylight or without darkening the room in which the pictures are displayed. My improved screen may also be readily rolled when not in use without danger of cracking or injuring the coated surface thereof.

Having thus described my invention what I claim is:

1. A process of producing a. moving picture screen which consists in subjecting an oil cloth base to a softening oil, then apply ing a coating of Jap-a-lac and turpentine to the softened surface of said base and allow ing it to partially dry. and then applying a metallic powder to said coating and rubbing it therein until a velvety sheen is produced.

2. A method of producing a screen of the r described consisting in softening the my hand in presence of two subscribing witsurfaee of a flexlble base hzwmg a glossy nesses.

surface then coating said so softened surface I Q with a mixture of varnish and turpentine, SAMUEL JONES and then rubbing a metallic powder there- Witnesses:
