Description
Oct. 29, 1929. v R. J. VJfllLlAM S ET AL SHEAR SURFACE RING FOR, PULVERIZING MACHINES Filed Dec. 11. 1926 Patented Oct. 29, 1929 warren *sTArss A CORPORATION OF DELAWARE SHEAR SURFACE RING roa runvnnrznve MACHINES Application filed December 11, 1926. Serial No. 154,097.
This invention relates to rings intended to be mounted on the reels of pulverizing machines of the rotary beater type, and has for its object to provide a construction of ring which, while involving in a substantial measure the function of roller reduction, will at the same time serve efiiciently as a hammer, and particularly with a shearing effect upon the lumps of material against which it acts.
The invention proceeds upon the principle of constructing a ring for use in the situation stated, with a tread of serpentine form, as, for instance, by developing in the periphery of the ring two circumferential series of recesses, opening alternately on opposite sides of the ring, and with the defining walls of the recesses inclined to the plane of the wheel so as to develop a continuous tread portion, zig-zagging back and forth between the sides of the ring. Thelatera-lly opening recesses extend radially inward from the periphery of the ring to the circumference of an inner body portion of annular form, and taper somewhat in depth from the outer face of said body portion inwardly. In the preferred design, the depth extends the axis of the ring well beyond the medial plane of the ring, so that the recesses overlap in the series. The effect of the form of tread referred to is to shear the fragments of mineral upon which it acts by the diagonal edges of the tread, develop a hammering effect by the inclination of the recess walls to the circumference of the ring, and produce a rolling effect upon the finer materials passing over the grating of the machine.
In the accompanying drawing-' Figure 1 is a vertical a pulverizing machine of the type in which the ring, constituting the subject-matter of the present invention, is intended to be used.
Figure 2 is a face view of one of the ring employed in Figure 1.
Figure 3 is an edge view of the same; and
Figure 4 1s a section on the line i -49 Figure 2.
1 represents the grating, 2 the revolving reel, and 3 rings carried by the reel in a pulverizing machine. The ring 3 is constructed with an annular body portion 4: having en- 'dial planes of the ring, so that the tread asin the direction of transverse section of RUSSELL J. WILLIAMS AND CHARLES ALBERT WETTENGEL, or STQLOUIS MISSOURI, nssrenons T0 sonrnnnir Mnncnnnsn srnnr COMPANY, on ST. LOUIS, MISSOURI,
larged central perforation 5 through means of which the rings are mounted upon the longitudinal rods 2* of the reel. The outer annulus of the ring is constructed with two I series of recesses 6, 7, extending radially inward from the tread of the ring to the body portion 4, and opening alternately on oppos1te sides of the ring and leaving between them a tread surface 8. The defining walls of the recesses 6 and 7 are inclined to both axial radial planes andcircumferential rasumes a zig-zag or serpentine course in extending around the circumference of the wheel. a
Among the advantages of the construction herein shown and described, are the provision of a substantially continuous rolling surface, and shearing cutting edges.
We claim:
1. In a pulverizing machine of the hammer type, a ring constructed for mounting with freedom of hammer action, said ring having a tread defined by two circumferential series of recesses extending inwardly alternately from opposite sides of the ring, and walls defining and separating the recesses, inclined to the circumference and intersecting the im-' pact surface of the ring in shearing edges.-
2. In a puverizing machine ofthe hammer type, a ring constructed for mounting with freedom of hammer action, said ring having a tread defined by two circumferential series of; recesses extending inwardly alternately from iopposite sides of the ring, andwalls defining to the circumference and intersecting the impact surface of the ring in shearing edges;
the said walls, collectively, producing-a serpentine or zig-zag impact surface on the ring. I
3; In a pulverizmg machine of the hammer I of recesses extending inwardly alternately. from opposite sides of the ring, and walls defining and separating the recesses, 1n-
clined to the circumference and intersecting the impact surface of the ring in shearing edges; the recesses extendlng inwardly from I andseparating the recesses,inclined I the opposite sides to a depth beyond the medial circumferential plane of the ring.
4. A ring for pulverizing machines comprising a circular body with a comparatively 5 lar e centralcircular opening, the marginal portions of the peripheral surface of said body being circumferentially corrugated to form series of annularly spaced lateral relatively shallow recesses in its peripheral 19 edges.
Signed at St. Louis, Missouri, this 18th day of November, 1926.
