ENSILAGE-CUTTER.
Specification of Letters latent.
Patented May 30, 1916.
Application filed April 22, 1915. Serial No. 23,157.
To all whom it may concern Be it known that 1, DAVID F. WVILLIAMs, a citizen of the United States, residing at Poultney, in the county of Rutland and State of Vermont, have invented a new and useful Ensilage-Cutter, of which the following is a specification.
This invention relates to ensilage cutters and is more particularly a continuation of application No. 831,017, filed by me in the United States Patent Ofiice on April 10, 1914, for improvements in machines for filling silos.
One of the objects of the invention is to provide a combined revoluble cutter and blower of novel construction the blades of which are adjustably mounted so as to be capable of minute'adjustment without danger of shifting out of the positions to which they have been adjusted.
A further object is to provide blades so mounted as to effect a shearing action in connection with a fixed cutter, said cutters operating inwardly toward the axis of rotation thereof so that the power exerted by the movable cutter increases during the continued engagement of the cutters with the material being severed.
A further object is to provide a movable cutter the active edge portion of which is offset whereby the retarding action which has heretofore been present due to the accumulation of gummy substances upon the blades, is overcome and the said cutter is capable of working freely.
With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the com-- bination and arrangement of parts and in the details of construction hereinafter described and claimed, it' being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the inven tion.
In the accompanying drawings the preferred form of the invention has been shown.
In said drawings :Figure 1 is a front elevation of the cutter head. Fig. 2 is a transverse section through a portion of said cutter head and showing one of the blades cooperating with a fixed blade of an ensilage cutting machine. Fig. 3 is an enlai-ged section on line AB Fig. 1.
Referring to the figures by characters of reference 1 designates a disk-like cutter head provided, at regular intervals with recesses 2 extending into the periphery thereof and terminating at shoulders 3 which diverge inwardly from those radii of the head intersecting the outer ends of the shoulders. Outstanding from the head at each shoulder are backing lugs 41 and fitting against the advancing faces of these lugs and alining with the shoulders are blower blades 5 each of which has a base flange 6 bolted or otherwise secured to the head. These blades are so positioned that, during the rotation of the head 1, they will act as fan blades to throw outwardly any material which may he directed into the path thereof.
Formed upon one side of the head 1 are opposed arcuate series of bosses 7 each of which has a bore 8 extending therethrough, there being a counterbore 9 within the free end portion of each boss and said counterbore being interiorly screw threaded. These counterbores are adapted to be engaged by threaded bushings 10 having angular heads 11 constituting seats against which the cutting blades 12 are adapted to bear. A bore 13 extends through each boss and registers with the adjacent bore 8 and with an opening 14 in the blade 12. A bolt 15 extends through the opening 14: and the bores 13 and 8 and is engaged by a nut 16 whereby the several parts are securely fastened together. Each blade 12 is preferably secured to three bosses, as indicated in Fig. 1 and, as shown in said figure and in Fig. 2, each blade has its cutting edge bowed inwardly in the direction of its length and offset outwardly, as shown at 17. Thus it will be seen that the heads of the bolts 15 are free to lap the outer faces of'the blades 12 without interfering with the cutting action, as will be seen by referring to Fig. 2, while at the same time the area of the blade brought into contact with the stationary cutter 18 is materially reduced with the result that friction is less and the danger of the operation of the apparatus being retarded by accumulations of gummy substances, is eliminated. It will be noted, furthermordthat the outer end of each cutting edge is in advance of the material being cut and said material is then sheared inwardly along the active edge of the stationary blade 18, so that the power exerted by the movable cutter increases during the continued engagement of the cutter with the material being severed. By providing the particular mounting of the blade illustrated, a very minute adjustment of the blade can be eifected, this adjustment being secured by placing a wrench upon the angular head 11 of the bushing 13 and adjusting said bushing into or out of the boss 7. The blade is then placed upon the head of the bushing 13 and the bolt 15 inserted through openings 14, bushing 10 and boss 7, after which the bolt is tightened, thus securely binding the parts together so that there is no danger of their shifting relative to each other. Subsequent minute adjustment of I the blade toward or from the cutter head can be effected by placing the wrench on the angular head of the bushing close to and back of the cutting blade and then screwing the bushing into or out of the boss, the offset edge portion of the cutting blade eliminating any possibility of said edge portion being injured by the wrench during this operation. By providing the offset edge portion of the blade, it becomes possible to use a bolt 15 the head of which can project outwardly beyond the cutting blade and bear against the outer surface of the blade, thus having a bore extending therethrough and through the head and having a counterbore, the wall of the counterbore belng screw threaded, a bushing screwed into each counterbore and having an angular head at its outer end, said head being provided with a flat outer face free of projecting portions, a blade bearing against said flat outer ends of the bushings and having a cutting edge, and bolts extending through the blade, bushings and bosses and having heads bearing against the outer face of the blade.
In testimony that I claim the foregoing as my own, I have hereto afliXed my signature in the presence of two witnesses.
