RICHARD WV. BAINBRIDGE, OF NEW YORK, N. Y.

PAPER-MAKING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 788,508, dated May 2, 1905.

Application tiled December 27, 1904:. Serial No.. 238,460.

To (r/ZZ 'whom 'lit 'nm/y concern:

Be it known that I, RICHARD W. BAIN- BRIDGE, a citizen of the United States, residing in the borough of Brooklyn, county of Kings, city and State of New York, have invented a certain new and useful Improvement in Paper-Making Apparatus, of which the following is a specification.

The present invention applies more particularly to apparatus for' making sheets of paper by hand; and the object is to provide a simple, portable, easily-handled mold utilizing the principle of gravitation in collecting the paper liber from the water in which the same may be suspended and distributing the same evenly upon a perfo'rate surface in order that a sheet of uniform texture and thickness may be produced without involving the employment of skilled labor, upon which the handmade-paper industry has heretofore depended.

In carrying out the invention I employ a mold which may take the form of a rectangular box, the top whereof may be provided with a gauze covering of suitable mesh, the

bottom whereof may, if desired, be detachable, and the sides whereof may be provided with suitable ports for egress of the air when such mold is immersed in water.

In operation upon immersing the mold in the water in which the fiber is suspended such water will under the iniiuence of gravity immediately pass into the mold, displacing the air therein, which is allowed to escape through the ports referred to, the fiber being arrested upon the gauze covering until the accumulation has been sufhcient to produce a sheet of requisite thickness, whereupon the mold may be lifted from the Water and the deposited fiber dried and otherwise treated in suitable manner.

The invention is illustrated in the accompanying drawings, in which- Figure l is a central section of a mold eniploying my invention. Fig. 2 is a top plan view thereof, a portion of the gauze covering being broken away; and Fig. 3 is an elevation on reduced scale, showing the mold immersed in water. n

Referring to the drawings, in which similar letters denote corresponding parts, it will be seen that the mold is here shown as rectangular in form,.comprising the four sides t a' a2 fand the bottom B, which is preferably detachable and provided with any suitable securing device whereby the same may be attached to said sides.

O designates the cover of wire-gauze of lsuitable mesh, and this may be secured in any desired manner in the position in which it is illustrated, detachably or permanently, as preferred.

D D designate ports or air-passages, here shown as two in number and each comprising a pipe connected with one of the sides of the mold and communicating with the interior thereof through an opening in such side.

The method of operation is illustrated in Fig. 3. |The mold is intended to be immersed, as above indicated, in the water in which the paper ber is suspended, whereupon under the pressure of such water the air will be forced therefrom through the ports or openings above indicated, and as the water passes into the interior of the mold the paper fiber will be laid upon the gauze covering C, the period of immersion being calculated with reference to the thickness of the paper to be produced.

Preferably the mold is of such height that a suiiicient quantity of fiber will be deposited upon the gauze before the water-level will rise to the ports. After the fiber has been laid and the mold removed from the tank the water may be freed from the mold in any suitablernanner as, for instance, by the removal of the bottom B. l

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is as follows:

I. In paper-making apparatus, the combination with a mold, of a closure for the bottom thereof, a foraminated closure for the top thereof, such as gauze, and a connection between the interior of said mold and the outside atmosphere, substantially as set forth.

2. 1n paper-making apparatus, the combination with a mold, of a closure for the bottom thereof, a forarninated closure for the top thereof, Such as gauze, and a port in said mold communicating with the outside atmosphere, substantially as set forth.

3. In paper-making apparatus, the combination with a mold, of a detachable closure for the bottom thereof, a foraminated closure vfor the top thereof, such as gauze, and a connection between the interior of said mold and the outside atmosphere, substantially as set forth.

4. In paper-making apparatus, the combination with a mold, of a closure for the bottom thereof, a foraminated closu re for the top thereof, such as gauze, and means for withdrawing air or water passed to the interior of said mold, substantially as set forth.

5. In paper-making apparatus, the combination with a container for water having paper liber suspended therein, of arnold adapted for immersion in the water in said container, said mold. having a Closure for the bottom thereof, and a closure for the top thereof of foraminated material such as gauze, and means for withdrawing the contents of said mold after the immersion thereof in said water, substantially as set forth.

This specification signed and witnessed this 19th day of December, 1904.
