PECIFIGATION forming part of Letters Patent No. 396,794, dated January 29, 1889.

Application filed October 8, 1 888. $erial No. 287,543- (N model-l To (all whom it may concern.-

Be it known that I, JACOB Wrssrns, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented certain new and useful Im provements in Fodder-Cutters; and I do here by declare that the following is a full, clear, and exact description of the same, reference being had. to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon, in which- Figure 1 is an isometrical view showing a portion of the frame. Fi 2 is an end view of the cylinder, showing the cuttii'ig-knives attached thereto. Fig. 3 is a detached isometrical view of a portion ofthe cutter-bar, showing a cutting-knife in proper position to commence cutting. Fig. -'l is a view of a portion of the cylinder, showing the manner of attaching the cutting-knives thereto. Fig. 5 is a detached view of one of the cuttingknives. Fig. 6 is a top view of one of the cutting-knives.

The present invention has'relation to fodder-cutters5 and it consists in the different parts and combination of parts hereinafter described, and particularly pointed out in the claims.

Similar letters of reference indicate corre sponding parts in all the figures of the drawings.

In the accompanying drawings, A represents the frame of the fmlder-eut-ter proper, which maybe snbstanti ally of the form shown, or it may be of any other desired construction, reference being had to attachingthe dif ferent parts thereto. To the frame is properly j ournaled the cylinder l3 by means of the boxes (L. To the cylinder H are securely attached the cuttingknives b by means of suit able cla1nping-bolts or their equivalents. For the purpose of adjusting the cutting-knives h laterally the elongated slots 0 are provided.

The cutter-bar O is provided with the bent or curved fingers d, which are located and arranged substantially as illustrated in the drawings, and for the purpose of strengthening these fingers the braces or ribs 0 are provided. These fingers (Z and the braces or {)ibs (61 are preferably formed integral with the The cutter-bar O is placed in the frame A substantially as illustrated, and for the purpose of security and rigidly holding the out ter-bar C in proper position the ends of said cutter-bar are provided with the ribs f, said ribs fitting in corresponding grooves located in the frame.

The cylinder B consists of the curved wings D, said wings being located and arranged substantially as illustrated in the drawings, and are integral parts of the cylinder proper. These wings D are twisted substantially as illustrated, and in this instance said ribs are twisted about one-fourth around, or what is commonly known as a quarter-twist.

For the purpose of attaching the cuttingknives l) to the wings D the ribs g are provided, said ribs beinglocated substantially as illustrated in Fig. 2. The cutting-knives b are bent or curved laterally to the cylinder proper, said curvature corresponding with the curvature of the fingers d. For the purpose of causing the knives b to cut in a shearing manner the outer ends of said knives are bent or curved in such a position that will cause the point of said knives to enter the spaces between the fingers d in advance of the heel portions of the knives, thereby causing said knives to cut in an easy manner.

For the purpose of causing the cuttingknives to enter between the fingers bat an angle to said fingers the center or shaft of the cylinder proper is located somewhat higher than the top of the cutter-bar C. I11 order to assist in holding the fodder laterally 011 the cutter-bar O and fingers cl, said fingers are slightly concaved, as illustrated in Figs. 1 and 3. It will be seen that by concaving the top of the fingers d the edges of said fingers will present sharp corners, thereby holding the fodder thereon. For the purpose of providing a continuous cut the fingers d, are curved to such an extent that will bring the rear portion of said fingers to one side of the forward ends of said fingers, as illustrated by the dot ted line 06 :0, Fig. 3.

For the purpose of providing a strong and secure attachment for the knives h the shanks h are formed of such a length 'that will pro vide a strong attachment to the wings D, said shanks overlapping each other, as illustrated in Fig. 4:. The object and purpose of lapping 7 cut, thus enabling me to cut hay or straw l be understood that rotary motion is to be coininunicated to the feed-rolls E in any convenient and well-known manner.

It will be seen that by providing the curved fingers (Z and the curved cutting-knives l), I am enabled to provide a continuous shear or without any change of parts. By adjusting the cutting-knives so that their front or forward ends will enter between the fingers (Z in advance of theheel portions of said knives the fodder will be drawn forward. The cutting-knives l) are so adjusted that the point of the next upper knife will commence to out next lower knife.

' In Fig. 2 the end of the cylinder is transposed from the position shown in Fig. 1, so as to better illustrate the curvature of the cutting-knives Z).

Having fully dcseribedflny invei'ltiou, what i I claim, and desire to secure by Letters Patent, is-- 1. In a fodder-cutter, the combination of the cutter-bar C, provided with the bent or curved fingers (Z, and the cylinder B, provided with the twisted wings D and having attached thereto the cutting knives b, said cuttingknives being bent or curved to correspond with the curvature of the fingers (Z, substantially as and for the purpose specified.

2. In a fodder-cutter, the combination, with the cutter-bar provided with the eoneaved fingers (Z, of the cylinder B, the wings D, and the cutting-knives l), substantially as and for the purpose specified.

E3. The cutter-bar C, provided with the bent or curved fingers (Z, the streiigthening-ribs e, the cylinder 13, provided with the twisted wings I), and the bent or curved cuttingknivcs l), substantially as and for the purpose specified.

4. The cutter-bar C, provided with. the bent or curved fingers (Z, the cylinder B, provided with the wings D, and the cutting-knives b, a little before the lettin go of the heel of the i having their outer ends bent below the heels of said knives Z), substantially as and for the purpose set forth.

In testimony that I claim the above I;- have hereunto subscribed my name in the presence of two witnesses.
