OLIVER J". WILLIAMS, OF BURLINGAME, CALIFORNIA, ASSIGNOR TO WILLIA'MS PATENT CRUSHER & PULVERIZER 00., OF ST. LOUIS, MISSOURI, A CORPORA- IION OF MISSOURI.
FEED-REDUCING- MACHINE.
Specification of Letters Patent.
Patented Jan. 3, 1922.
Application filed November 26, 1918. Serial No. 264,184.
To all whom it may concern Be it known that I, OLIVER J. WILLIAMS, a citizen of the United States, residin at Burlingame, in the county of San l ateo and State of California, have invented certain new and useful Improvements in Feed- Reducing Machines, of which the following is a specification.
This invention relates to certain new and useful improvements in feed reducing machines and having special reference to the hammers and breaker plate.
The main object of my invention is to provide means for splitting and breaking up the material having long stiff fibers, such as corn stalk and the like, and reducing the same to any desired degree of fineness.
In the accompanying drawing on which like reference letters indicate corresponding parts, Fig. 1 represents a perspective sectional view of a machine embodying my invention;.Fig. 2 a detail view of my double-toothed hammer and part of a matching breaker plate, Fig. 3 is a similar View of my single-toothed hammer; Fig. 4: is a similar view of the hammer shown in Fig. 3, but in reversed position, and F ig. 5, a similar view of. my multiple-toothed hammer.
The letter. A designates the casing of a reducing machine provided with a top B and a feed inlet hopper C of suitable construction. In said casing is mounted a shaft D having discs E or other hammer supports for a series of stirrup hammers, such hammers comprising a pair of shanks adapted for pivotal connection at one end of said discs, or other hammer supports, and having at their outer ends a transverse bar Connecting said shanks and adapted to cooperate with a suitable breaker plate F adjustably mounted at the inner end of the feed inlet and co-operate also with a suitable cage G of open bar or other style.
Referring now to my special form of hammer,the shanks are preferably made of flat bar steel of relatively greater width than thickness and have at their inner ends a hole for a pivotal bolt connecting each shank with the hammer support on the respective side, or otherwise adapted for pivotal mounting. The outer ends of said shanks are connected by a transverse bar, likewise of greater relative width than thi kness such as would. be formed by bond,-
ing the stock bar of which said shanks and transverse bar are made, into the toothed form illustrated in the accompanying drawing. In this construction the lesser dimension of the bar is presented as the forward operative edge to the feed material entering said hopper, and by the co-operative action of a suitable breaker plate the long fibers of the feed material are broken up transversely when they slip sidewise into said hopper, and are split when they slip or are fed endwise into said hopper.
Referring to Fig. 2 it will be observed that the shanks G are connected by a transverse bar having angular \lwshaped projections H, forming teeth, which are separated by a straight portion I. In this form the teeth H are located directly adjacent to the shanks G. r
In the form shown in Figs. 3 and 4: one tooth H is located at one side of the middle of said transverse bar, and thus nearer one shank than the other, whereby this singletooth hammer is capable, by reversing it in its hammer supports, of operating with two corresponding portions of the matching breaker plate F.
In Fig. 5 I have shown a'multiple-toothed hammer and portion of co-operating breaker plate in which the connecting bar I before mentioned is wholly made up of teeth H which co-operate with the notches of a suitable breaker plate as shown.
In practical operation I may thus provide a reducing machine with pivoted hammers having one or more teeth so mounted as to follow each other successively but act upon a different portion of the breaker plate, or co-operate with a difi'erently located notch in said breaker plate respectively, according to the location and number of the teeth II as above described.
In certain kinds of feed material such as tailings for fertilizer in which the reduction is coarse, or is not required to be finely reduced, the breaker plate may be other than of the toothed and notched form shown in connection with my toothed hammer. That is to say, my toothed hammer would break up split and otherwise reduce to roughage the material fed to said hopper when of such coarse construction and growth that a finely reduced output would not be required.
. 1 the ther hand, I have h wn the breaker plate as adapted for adjustment inward and outward by means of screws J, Fig. 1, whereby the space between the teeth, and therefore the fineness of grinding, may be varied as desired.
In this application the term stirrup is used to designate a double-shank hammer with connecting cross bar at the outer end of said shanks, as distinguished from a single-shank hammer.
In addition to the splitting and breaking action of the toothed hammer above described, it is evident that by providing such teeth on the connecting bar, especially in the multiple form of hammer above described, I have largely increased the cutting edge of the hammer,-that is, practically doubling the length of cutting edge when formedas in Fig. 5, over a straight connecting bar as in, a plain stirrup hammer.
Thus it will be seen that when a flat bar. of steel or other material is bent up into two parallel shanks of equal length, separated a suitable distance, and connected at the outer ends of the shanks by a head that is bent inward and outward in inclined planes forming teeth alternating with hollows upon both the inner and the outer edges of the cross bar head, said teeth and hollows lie in a plane through the shanks and pivot points and present cutting edges to reduce the material in connection with the breaker plate and also act upon the material inside of the stirrup hammers between the shanks. The cross bar head forms a zigzag line with inner teeth and outer teeth between the outer ends of the double shanks, and when the teeth are irregularly disposed in the head they follow each other alternately in their circumferential motion about the shaft, and therefore alternate with the respective hollows of the said breaker plate and act upon the material as before described.
I claim:
1. A machine of the character described comprising rotary pivoted hammers each consisting of a flat rectangular bar of greater width than thickness, consisting of shanks having pivot holes at their inner ends and connected by a cross bar at their outer ends, said bar being formed into multiple teeth presenting the lesser dimension of the bar as a cuttingedge, substantially as shown and described.
2. A machine of the character described comprising rotary pivoted hammers each consisting of a fiat rectangular bar of greater width than thickness and having shanks with pivot holes at their inner ends,
and connected by a cross bar head formed into multiple teeth by successively bending the bar on its lesser dimension, thereby forming teeth alternately on the outer and inner face of said bar, andpresenting operative cutting edges by the lesser dimension of the bar, and alternately disposed teeth on the outer and inner faces, substantially as shown and described.
3. A machine of the character described comprising rotary pivoted hammers each consisting of a fiat rectangular bar of greater width than thickness consisting of shanks having pivot holes at their inner ends and connected by a toothed cross bar at their outer ends,-the said toothed cross bar and shanks presenting the lesser dimension of the bar to the material being reduced and thereby effecting a slicing action thereon, substantially as described. 7
In testimony whereof I have affixed my signature.
OLIVER J. WILLIAMS.
