MARSHALL MILL Filed March 18. 1929 2 Sheets-Sheet 2 Patented Feb. 23, 1932 UNITED STATES FRANK J. MARSHALL, OF EASTON, ZPENNSYLVANIA, ASSIGNOR TO LUCY G. MARSHALL, OF SPRINGFIELD, MASSACHUSETTS MILL Application filed March 18, 1929. Serial No. 347,773.
This invention relates to an improvement in grinding and hydrating mills and while particularly adapted to mills for hydrating pulp used in the manufacture of paper, is also adapted for use in grin v.mg coal or cei'uent.
The general construction of the mill is like that shown in patent granted to me February 21, 1911, No. 984,830, for pulpbeating engine,
which includes a conical case, a bed-plate, l0 and a conical plug with a disk having cntters co-acting with the cutters on the bed plate. In some forms of pulp and in grinding coal or cement, there is tendency to clog, and the object of this invention is to so con struct the conical casing and conical plug that clogging is less liable to occur, and in pulp raw stock may he hydrated in very much less time than has heretofore been necessary.
My invention further consists in a grinding and hydrating mill having certain details ot construction and combinations of parts as will be hereinafter described and particularly recited in the claims.
In the accompanying drawings:
1 is a view partly in section of a grind ing mill constructed in accordance with my invention;
Fig. 2 is a sectional view on the line 2-2 of Fig. 1;
Fig. 3 is a sectional view on the line 33 of Fig. 1;
Fig. 4 is a side view of the cone detached;
Fig. 5 is an end view thereof;
Fig. 6 is a face view of a. portion of the disk, showing the segmental cutter-plates applied thereto; and
Fig. '2' is a corresponding view of a portion of the hed plate, showing cutters applied thereto.
In carrying out my invention, I employ a machine substantially like the machine shown in the above-mentioned patent and including a conical case 10, a conical plug 11, means for mounting the conical plug for revolution within the casing, a disk 12, and a bed-plate 13. In this case the cone is lined with segmental plates 14 bolted to the casing, these plates being provided with closely-arranged recesses 15 forming a plurality of pockets which will tend to hold the material being operated upon. The cone llis formed with a plurality of grooves 16, herein shown as four in number, extending longitudinallyof the cone and gradually increasing in width and depth toward the larger end, and secured to the surface of the cone between these grooves are segn'lental plates 17 having longitudinal ribs 18, and beyond these plates 17 are continuing-plates 19 having angular pockets 20 like the pockets 15 in the casing. The inner face of the disk 12 is provided with segmental plates 21 having radial ribs 22 and a bedplate 13 is provided with complementary plates 23 having staggered ribs 24; coacting with the radial ribs 22 on the disk.
The operation of the machine will be readily understood. Stock is fed to it at the smaller end of the casing and is crushed between the surfaces of the cone and casing, and due to the formation of the plates applied to these members, a rubbing action is secured, so that the material is crushed witl1- out actually cutting it. The grooves tend to force the stock between the bed-plate and disk, so that it is further crushed between them. By providing the cutter and casing with the incrcasinglytapercd grooves as described, the taper on the casing and cutter is reduced to the minimum and yet an increased amo-unt of stock may be treated in the machine.
I claim:
1. In a mill, the combination with a conical casing, of a cone mounted in said casing, said con-e formed with longitudinally-tapered grooves widening toward the larger end of the cone, and longitudinally-ribbcd plates and angular pocketed plates secured to the surface of the cone between said grooves.
2. In a mill, the combination with a conical casing lined with segmental angular pocketed plates, of a cone mounted in said casing, said cone formed with longitudinally-tapered grooves widening toward the larger end of the cone, and longitudinally-ribbed plates and pocketed plates secured to the surface of the cone between said grooves.
3. In a mill, the combination with a conical casing, of a cone mounted therein and adapted to be revolved, said cone formed with longitudinally tapered grooves widening toward the larger end of the cone, and a bed-plate and a disk, said plate and disk provided with segmental complementary cutters. V
4. In a mill, the combination with a conical casing,-of a cone mounted therein and adapted to be revolved, said cone formed with longitudinally tapered grooves widening toward the larger end of the cone, and
a bed-plate and a disk, said plate and disk provided with segmental complementary cutters, the cutters on one member being radial and the cutters on the other member being staggered with relation thereto.
In testimony whereof, I have signed this specification.
FRANK J. MARSHALL.
