GRINDING-MILL.
Specification of Letters Patent.
Patented Mar. 29, 1910.
Application filed December 27, 1909. Serial No. 535,062.
Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Grinding- Mills, of which the following is a specification.
My invention relates to improvements in grinding mills and the objects of my improvements are simplicity and economy in construction and convenience and efficiency in use.
Inthe accompanying drawing :Figure 1 is a longitudinal section of part of a grinding mill embodying my invention, certain partsbeing in side elevation. Fi 2 is a back view of the moving grinding disk Fig. 3 is a similar view of the hub which supports the moving rinding disk, the position of the movingd isk being indicated by broken lines. Fig. 4 is a front view of the hub. Fig. 5 is an enlarged view of certain of the parts shown in Fig. 1.
A is the lower body and base of a grinding mill and comprises the lower half 10 of an operating chamber in which are housed the grinding disks, comprising a stationary disk B and moving disk C and is provided with means for supporting the bearings D for the shaft E which carries the said moving disk C, which bearings may be a ball hearing as shown. The said shaft extends through the stationary disk B and a partial hopper 11 on one side of the same and overhangs the bearing D on the same side as the said hopper 11 and supports on the outside a combined crank and fly wheel F, and is operatively connected to the same through the medium of an adjusting screw G, all in a manner well known. The said stationary disk B is of well known construction and comprises on the back face the grinding face or disk proper 12 having the usual ribs and teeth, and on the front face said partial hopper 11, the said disk and hopper being pierced to admit the shaft E as described. The shaft hole 14 in the hopper is of a size to allow clearance for the shaft and the hole or passageway 15 through the stationary disk B admits the material to be ground. On the outer edges the stationary disk B is provided with lugs for holding the same in place in engagement with correspondin lugs on the body A. The moving disk 6 comprises on the front face an annular disk 17 provided with the usual ribs and teeth, and constituting the grinding face, opposed to the said stationary grinding face 12. A
I claim as my invention 2- 1. In a grinding mill having a moving disk, a hub, and a shaft, the said hub having means for being rigidly secured to said shaft, and provided with a bearing rib concentric with the said shaft, radially exterior to the said rib having an annular web provided with radial slots, the said disk provided With a bearing surface adapted to engage in abutment with the said rib and with lugs adapted to engage with and be driven by the walls of the said slots.
2. In a grinding mill having a shaft and a grinding disk, a hub provided with means for being rigidly mounted on said shaft and in abutment with the said grinding disk, the confronting faces of the said hub and disk provided with circular bearing ribs in abutment with one another and projecting gening extending radially exterior to said hub an annular web provided with means for engagement with said disk, and the said' disk provided with a circular rib in abutment with said rib on said hub, the sald hub inwardly from said rib provided with a recess extending away from said disk adapted as a recelving chamber for.unground material.
