Description
HEZEKIAH DODGE, OF ALBANY, NEW YORK, ASSIGNOR TO NEW YORK WOOD-PULP COMPANY OF VNEW YORK CITY.
IMPROVEMENT IN MACHINES FOR THE MANUFACTURE OF WOOD-PULP.
Specification forming part of Letters Patent No. 122,581, dated January 9,1872; antedated December 23, 1871.
- ful Improvements in Machines for Shaving and Cutting Wood for the Manufacture of Paper- Pulp; and I do hereby deciare the following to be a full, clear, and exact description of the same, reference being had to the accompany ing drawing forming part of this specification, in whichvFigure l is an end elevation of the cutter head. Fig. 2 is a longitudinal vertical section representing certain parts of the head. Fig. 3 is a plan of the plate to whichthe cuttingblades* are attached; and Fig. 4is a plan of the saine with the blades.
Similar letters of reference indicate like parts.
This invention is an-improvement upon the machine for which Letters Patent of the United States were granted to me January 25, 1870, No. 99,071; and the invention consists in a new construction of the plates that support the knives, and a novel arrangement of the knives, as hereinafter set forth. v
In my former machine I employed a conical head with asystem of blades arranged longitudinally of it in aradial plane, their edges projecting through the walls of the head into the interior thereof, striking the log almost perpendicularly to its surface at the point of contact, and thus scraping over it as the cutter rotated. In my present invention I construct the head of two parallel annular plates,
. b c, of equal diameter, but unequal bore, ar-
ranged at a suitable distance apart with their centers in line, connected by two or more tapering dat plates, c a, which support the blades es. The wide end of the plates a is attached to the ring c, (which has the smaller opening,) nearly in a radial plane through the center thereof 5 but the narrow end of the plates is carried obliquely to the ring b and fastened to it, not in a plane radial to the center, but in one which is nearly tangential to the bore. 'lhe result is, that the edges of the blades are not in a line with the axis ofthe cutter-head in any direction; but they strike the log nearly tangentially and cut it obliquely to a conical point, producing a clean iiossy fiber, very much superiorto that produced by the former machine.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. The rings b c, in combination with the tapering plates a a a, arranged obliquely to the axis of the head, substantially as and for the purposes described. I
2, The combination of the rings b c, plates a, a; a, and blades s `s s, constructed and arranged substantially as and for the purposes specified.
3. A cutter-head in which the cuttin g-blades s .s s, suitably supported, are arranged in a line oblique to the axis of the head, and with their cutting-edges so disposedas to cut the log to a taper, substantially as described, for the purposes set forth.
HEZEKIAH DODGE.
