SPECIFICATION forming part of Letters Patent No. 352,960, dated November'23, 1886.

7 Application filed J uly 3, 1886. Serial No. 207,069. (No model.)

clare that the following is a full, clear, and ex act description of the same, reference being had to the annexed drawings, making a part of this specification, and to theletters and figures of reference mark'ed thereomin which-- Figure 1 is a perspective view of my improved straw-cutter, parts being broken away.

Fig. 2 is a detached view of the cutter-bar.

Figs. 3 are detached views of the main shaft, showing one of the rotary arms attached thereto and the knives placed in position, to be properly attached to-said rotary arm. Fig. 4 is a detached view of a portion of the lower feed-shaft, showing three sections of thefeedrollers located thereon. Fig. 5 is a detached view of a portion of the upper feed-shaft,showing a section of a feed-roller located thereon. Fig. 6 is a detached view of the bracket and pin for changing the speed of the rollers. Fig. 7 is a top view of a portion of the cutter-bar and one of the rotary arms properly located on the main shaft.

The presentinvention has relation to foddercut-ters; and it consists in the different parts and combinations of parts hereinafter described, and particularly pointed out in the claims.

Similar letters of reference indicate corresp onding parts in all the figures of the drawings.

A represents the frame, which may be substantially of the form shown in Fig. 1, and, as shown,is properly braced,so as to rigidly hold the same.

To the front or forward end of the frame A are securely attached the plates or bars a, said plates or bars being provided with suitable bearings for the main shaft B, said shaft B being located substantially as shown in Fig. 1.

To this main shaft B are attached the rotary placed in the position shown in Figs. 3, and for the purpose of securely holding the rotary arms C.

At agiven place on the main shaft B the set-screws c are provided, as shown in the drawings. 'To the ends of the rotary arms 0 are adjustably attached the knives D. Said knives are substantially of the form shown in the drawings, and are securely attached to the rotary arms 0 by means of the clamping-bolts d, or their equivalents. For the purpose of adjusting the knives Him or out from the main shaft B the slots e are provided, as shown in the drawings. of the form shown, and, as shown, are provided with the shanks D, which are integral with the knives D, the knives D being at an angle to the shanks, and when properly attached to the rotary arms 0 will be at an angle to said arms. The rotary arms 0 are placed spirally ,on the main shaft B, as shown in Fig. 1. The

The knives D are substantially object and purpose of so placing the rotary arms 0 are that but one knife will cut at any one time, thereby causing the fodder to be out much easier. I

The cutter-bar E is substantially of the form shown in Figs. 1, 2, and 7, and is securely held in proper position by means of clamping-bolts or their equivalents. I prefer to attach the cutter-bar to the plates or bars at This cutterbar E is provided with diagonally-arranged teeth f,which are formed integral with the bar E. The teeth f are so adjusted that their side faces will be in line with the knives D when said knives pass between them. The knives D are placed upon opposite sides of the rotary two knives upon one of the, rotary arms will pass between two of the teeth f.

It will be seen that by means of the setscrews 0', Iam enabled to adjust the knives D to or from the teeth f, and thereby regulate the cutter-bar andknives for different kinds of fodder. To one end of the shaft Bis rigidly attached the pinion F, which meshes into the wheel G.

To the side of the'wheel G is attached or placed the pinion g. This pinion g may be formed integral with the wheel G, or it may be formed separate and attached in .any we1larms 0, as illustrated in Figs. 3, so that the IOO known manner. The pinion g communicates motion to the wheel H, which isrigidly attached to the lower feed-roller shaft, as shown in Fig. 1, motion being communicated to the upper feed-roller shaft by means of ordinary finger gear-wheels. The wheel G and pinion g are mounted on a stud or pin, K, projecting from one end of a bracket, L, having a slot, M, for passage of a screw by which it can be adjustably attached to the machine-frame.

The feed-rollers I are formed in sections and strung on the shafts, as shown in Figs. 1, 4:, and 5. The rollers I, designed and calculated for the lower shaft, are fluted or corrugated, as shown in the drawings. The rollers designed and calculated for the upper shaft are provided with the cleats J, which are located substan tially as shown.

It Will be seen that by forming the feedrollers I in sections machines of different widths can be made by increasing or decreasing the number of sections. It will be understood that the feed-rollers proper should be pressed against each other by means of springs.

For the purpose of changing the speed of the feed-rollers I, the pinion 9 may be formed of different diameters and adjusted to the wheel H by moving the pin K, on which the pinion 9 turns, to or from the wheel H. For

this purpose the pinion g is preferably made separate from the wheel G, but capable of being secured thereto in any suitable manner.

' Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is v 1. The combination, with the diagonallytoothed cutter-bar E, of the rotary shaft B, the arms 0, connected in pairs by collars and adjustably secured to said shaft in different plane's, thereby forming a spiral thereon, and the knives D, adjustably secured to the ends of said arms with their cutting-edges standing at an .angle thereto, substantially as described.

2. The combination of the feed-rollers I, the toothed cutter-bar E, the rotary shaft B, having pinion F, the arms 0, mounted on said shaft and provided with knives-D, the adjustable bracket L, having slot M and stud K,the wheel G and pinion g, mounted on said stud, and the wheel H, attached to the lower feedroller, substantially as described.

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