To aZZ whom it may concern: of the frame. These makingwires are of Be it known that we, CHARLES H. CASE, a common construction, but have a novel arresident of Highland Park, and JOHN GRAY, rangement.

out the disadvantage of either, the machine being capable of forming the stuff into a sheet of any desired thickness from the thinnest to the thickest.

It is to be noted that the stuff is delivered to the hopper, two of the Opposing sides of which are formed of the making-wires that travel from the top to the bottom of the hopper and approach each other as they near the bottom. The stuff is supplied to the hopper mixed with a large amount of water and in uted throughout the quantity sufficient to maintain the level of the-stuff within the hopper at the required height. As the fluid mass descends under the action of the traveling making-wires it is gradually compressed more and more as it nears the bottom of the hopper, the water at the same time being forced out to a degree through the making wires composing the walls of the hopper. The adjustable side parts determine the width of the sheet, and by the time the sheet passes around the guideroll 0 at the bottom of the hopper the mass of fiber is formed into a sheet of quite regularconsistencyand veryhomogeneous. From this point it is carried along, passing between the lower making-roll b and the press-roll g, and thence between the felt roll f and pressroll h, from which point it is conducted to further press-rolls or dry'ing-cylinders,as may be desired.

An advantage derived from this construction resides in the fact that foreign material, as quite large strips or pieces of tobaccostalks or the like, can be regularly distribmass as it is formed into a sheet, thus giving to both sides of the sheet when finished all of the advantages which may reside in a fabric by reason of the presence of such material therein, the surface of both sides of the sheet being. alike and capable of use.

The term making-wire has been used throughout the specification and in the claims to designate those parts which act upon the pulp while contained in the hopper and for removing it therefrom; but we do not desire to limit ourselves to a making-wire in the sense that it shall be composed of a metal fabric, as it is intended and understood that any fabric which accomplishes the desired result shall be within the intent and scope of the invention and included in the term makingwire. as used herein.

What we claim as our invention, sire to secure by Letters Patent, is-
