METHOD OF REDUCING FIBROUS SHEET MATERIAL.
ducing fibrous sheet material such as sulphite paper board, the peculiarities of which will be hereinafter fully described and claimed.'
The main object of my invention is to re- 'duce sulphite paper board or like fibrous material from its comparatively hard pressed sheet condition to a fluffy, finely divided, comminuted state for further preparation in the manufacture of paper.
In the accompanying drawing on which reference letters are used to identify the parts described, the single view represents, partly in perspective, a diagrammatic view of the-'preferred means for carrying out this method; l
The letter A designates a shredding machine in the form of a grinder having `rotary pivoted hammers-B formed by rectangular bar steel; the outer end of each is chamfered off to allow for clearance'in operation, and thefront forward face is drawn forward and sharpened to present a cutting edge the vlength of which corresponds to the thickness 'of the bar, and is adapted' to slice a thin elongated sliver from the board or sheet of material that is passed between 'n compression rollers C and D, and extends inward over` the edge of a cutter bar D into the path of the said' hammers, whereby said slivers'of the material are lirst cutupon the cutter bar and then are carried down for further action in "connection with a perforated cage E. As said slivers are forced outward through the perforations in the cage they are cut crosswise into shorter pieces, and are also further divided lengthwise by the cutting edges of the rotary hammers operating in close proximity to said cage. l
The material thus divided, passes through the cage as indicated in the figure, and. is

acted upon by a blast of air entering at F and carried along outward from beneath the shredding machine into a'pipe G that is connected tol an exhaust fan H. The fan has a discharge 'pipe I that rises from the outlet of the fan vertically, and is bent over at its upper end into tangential connection with a cyclone collector .lof the usual or any approved style, from the bottom end of which it is discharged by a pipe K to the floor 4or a suitable receptacle. The outlet end of the cyclone collector is connected by a pipe L with a rotary or other suitable form of collector M, adapted to catch ,the finest particles and dust that is discharged from the cyclone collector.
After the mechanical division of the sulphite paper board into slivers by the cutting' edges of the rotary hammers B, and the furtherl division of said slivers in connectlon wlth the cage E` the air blast takes up vthe finely divided material and, by its ac- The longer fibrous porreadily acted upon in the further prepara tion of print paper, and for other purposes in which such changed` condition of thematerial is desirable.
