NITED STATES PATENT OFFICE.
THOMAS F. HOXSEY, OF PATERSON, NEW JERSEY.
MANUFACTURE OF PAPER-PULP FROM WOOD.
SPECIFICATION forming part of Letters Patent No. 231,720, dated August 31, 1880.
Application filed May 27, 1880. (No model.)
- SEY, of Paterson, in the county of Passaic and the State of New Jersey, have invented an Improved Process for the-Manufacture of Paper-Pulp from Wood; and I do hereby declare that the following is a full, clear, and exact description thereof.
My invention has forits objects the production of a long fiber pointed at the ends and broader in the middle, of greater orless length, according to the desire of the manufacturer, and to effect these results entirely by mechanical means, thus avoiding the use of chemicals and furnishing a pulp which is, without their employment, fit for use in the paper-makefis' vats.
In carrying out my process I take wood of any suitable variety, and saw it into blocks at (or as near as practicable at) a right angle with the grain of the wood, which is thus left from one-eightl'i of an inch to one inch in extent, measured from one out side of the blocks to the opposite cut side-that is to say, I saw oft the blocks in thicknesses ran gingfrom onceighth of an inch to one inch. The blocks thus out are then laid upon a firm support of some suitable solid material-say a smooth flatfaced mass of ironin such manner that the grain of the wood is in a vertical position relati vel y with the said face, and the blocks are then hammeredupon the cut ends of the grains therein till the blocks are reduced to fiber ot' the requisitefinene'ss. I preferably use a triphammer for thus disintegrating the wood, but of course do not confine myself to such a machine. The effect is to separate the wood into its cellular fibers without materially breaking these fibers across, and hence to produce a paper-stock of equal strength, capable of making a stronger and more perfect article of paper than can be done with pulp of shorter fiber, or fiber partly broken between its ends.
I claim as my invention The herein-described process of manufacturing paper-pulp from wood, which consists in first sawing the wood at (or as nearly as practicable at) a right angle with the grain into blocks of various thicknesses, according to the nature of the fiber to be produced, and then subjecting these blocks to hammering applied in the direction of the end of the grain till the blocks are reduced to pulp of the required fineness, substantially as and for the purposes set forth.
