MACHINE FOR PREPARING PAPER FOR STEREOTYPE=MATRICES.

, SPECIFICATION forming part of Letters Eatent No. 695,239, dated March 11, 1902.

Application filed August 20, 1901. Serial No. 72,700. (No model.)

To all whom it may concern:

Be it known that 1, ROBERT MARION SE- vERs, a citizen of the United States, and a resident of the city of-New York, borough of Manhattan, in the county and State of New York,

have invented a new and Improved Machine for Preparing Paper for Making Stereotype- Matrices, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved machine for making stereotype-matrices of any desired thickness and length, the machine being arranged to form the webs into a very homogeneous sheet cut into the desired length for the matrix.

The invention consists of certain novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claim.

A practical embodiment of my invention is represented by the accompanying drawing, which is a sectional side elevation of the improvement. v

On a suitably-constructed frame A is held a paste-pot B, containing paste such as is now employed in the manufacture of paper matrices. In the paste-pot B are arranged guides 0, preferably in the shape of rollers, located one above the other and extending in a transverse direction, so that paper webs D unwinding from reels E are passed separated one from the other under the said guides O to pass into the paste contained in the pastepot for coating both sides of the webs D with paste. The reels E are journaled on the frame A, and supplementary guides F are employed for sundry of the webs D to properly guide the same to the guides O.

In front of the paste-pot B is arranged a set of longitndinally-extending pressure-rollers G G, geared together and driven by suitable mechanism from a main shaft I-I, connected with other machinery to rotate the pressure-rollers G G in unison, the said pres sure-rollers being also geared to a second set of pressure-rollers G G arranged in front of the pressure-rollers G and G and spaced somewhat therefrom, as is plainly indicated in the drawing.

Two reels E and E are journaled on the frame A and are arranged relative to the pressure-rollers G G, so that the paper webs D D unwinding from said reels pass onto the peripheral surfaces of the pressure-rollers G G to receive between the webs D D the other webs D as the same come out of the paste contained in the pot B. Thus the webs D D pass uncoated to the pressure-rollers to receive between them the coated webs D, and all the webs now pass between the pressurerollers, so as to be pressed together to form a homogeneous sheet D which is cut into desired lengths or pieces by a suitable cutting mechanism I, preferably located between the sets of pressure-rollers G G and G G The mechanism for actuating the cutting device I may be of any approvedconstruction, and hence it is not deemed necessary to show and describe the details thereof.

The sheet D as it leaves the set of pressure-rollers G G passes upon a table .I, from which the matrix-sheets may be removed whenever desired. From the foregoing it is evident that the coated as well as the uncoated webs are very firmly united to form matrix-sheets of a very high quality, it being understood that any desired number of coated webs D may be passed to and between the dry sheets D and D to form a matrix -sheet of the desired thickness.

It is evident that the machine described is capable of producing a large amount of matrix-sheets in a comparatively short time.

Having thus fully described my invention,

I claim asnew and desire to secure by Letters Patent- A machine for preparing paper for making stereotype-matrices, comprising a frame, a pot for holding a liquid adhesive, a plurality of independent rollers journaled in said pot below the normal upper level of said adhesive, for the purpose of carrying moving webs of paper into and out of contact with said adhesive, pressure-rollers adjacent to said pot for squeezing the webs of paper arriving therefrom, separate rollers located re spectively above and below said pressurerolls, for feeding dry webs of paper respectively above and below said webs arriving from said pot, cutting mechanism adjacent to said pressure-rolls, and separate pressure rolls adj acent to the said cutting mechanism. In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ROBERT MARION SEVERS.
