Fig. 15 is a perspective showing a V-shaped knife, a splitter, and knife-holder. Fig. 16 is a section on line yy, Fig. 15. Fig. 1.7 is a perspective of a gage-pin shown at lower end of Fig. 16; and Fig. 18 is a front elevation showing the parts when adapted for the use of V-shaped knives,as shown in Fig. 15. Fig. 19 further illustrates the chain-guides.

A denotes the feed-box, and B cast-metal sides, which are similar in form, but made in pairs. The sides form the frame and support for the mechanism, and are supported on legs 0. The sides 13 have offset portion D on line w on, Fig. 1, by which the front portion of the frame is reduced to the width of the rear end of the feed-box A, or substantially so, the rear end of the side boards of the feed-box being secured on the inside of the front portion D of the frame. In this portion of the frame are provided j ournal-boxes for the feedroller shafts at. There are also provided in the front lower portion sockets for the front legs 0.

In the rear portion of the frame B are provided journal boxes I), in which are journaled' driving-shaft c and journal-boxes cl, in which is journaled the lower chain-wheel shaft 6. At the top portion of the frame side B are provided slots f, in which are placed vertically-slidable journal-boxes g, in which is journaled the upper chain-wheel shaft h. The journal-box is supported on a tensionspringj, one end of which is supported on an outwardly-projecting lug 7c, the other end supported on a tension-screw Z.

At the rear side of the feed-rollers E and F is secured by its end portions to the front portion D of the sides B the stationary knife G. Gear-wheels and chains of the usual and well-known form are applied to connect the roller-wheels a and rollers E and F with a driving mechanism in any of the usual and well-known ways, by which rollers the fodder is fed rearwardly upon and over the stationary knife G, the ends of which are passed through the portion D of the sides B, and be tween lugs n, projected forwardly from the offset or shoulder, as shown in Fig. 4:, and secured by the set-screw 0, turned onto the inclined surface of the recess 19 in the end of the knife.

To the inside face of the frame sides B are pivotally secured slides or guideways II by the bolt g at the upper end portion of the guide. At the lower end portion is provided a spring 7", resting on lugs on'the guide. (See Figs. 6 and '7.) Against this spring is rotated a crank portion or pin 8 on a head J, that is journaled in the sides B, on the outer end of which is secured a pointer or register K, which will be explained hereinafter.

The journal .9 of the head J has a squared portion 8 on which is placed the pointer K, which is secured by a screw 5 which enters a threaded aperture in the journal, as seen in Fig. 7.

In the shafts h are mounted chain-wheels L, and on shaft 6 are mounted similar wheels L, about which are placed chains M, in which are placed at desired intervals links, as N, having therein centrally thereto a lateral cir-. cular aperture t, that serves as a journal-box for the pin or journal a, projected from the side of the knife holder or bearer 0, (see Figs. 2 and 10,) and at other desired intervals links, as P, having a laterally-projected pin 1), adapted to pass into the slot win the knifebearer. On the inner face of the knife-bearer is provided an inwardly-projected ledge y, to which the knife Q is secured. The knifebearers are similar in form, but made in pairs to adapt them for use on the two sides of the machine, and to secure the desired angle of the cutting edge of the knife Q as it passes the stationary knife G the links N and P are placed forward or back in the chain, and by the same manipulation of said link the angle of the knives Q may be set to cut in opposite directions or parallel with the stationary knife. At the forward end of the knifebearer O is provided a lug d, to which is secured a crossbar or spreader R, as shown in Fig. 1.

The chains M are placed about the chain or sprocket wheels L and L, the knife-bearers with knives secured thereto, as hereinbefore described.

To operate the machine by hand, a crank S is placed on the right-hand end of shaft 0, andon the opposite is mounted a gear-wheel T, that engages a similar wheel U 011 shaft 6, that carries chain-wheels L, by turning shaft 0 by the crank in the direction indicated by the arrow. The chain-bearers with the knives secured thereto will be carried up over and down between the guides II and the fixed knife G, to sever the fodder that has been passed over the knife G, by the rollers E and F, as hereinbefore stated, and to provide against accident, or the knives Q striking too violently against the knife G, and to secure a desired adjustment, the spring a" and crank-pin .9 (shown in Figs. (3 and 7) are provided, as hereinbefore mentioned. By turning. the pin 8 against the spring, the pressure of the knife Q, against the knife G may be regulated.

The heads J are journaled in the sides B of the frame, at points opposite the lower parts of the guides H, the latter being pivotally connected, at their upper ends, with the sides by bolts q, and the crank-pin s of each head extends into one of said guides and is adapted to bear against the spring 9' when the head J in the opposite direction, the guide may be moved from the path of the knifebearers. The index-pointer K, outside of the frame, is used to turn the head J and also to indicate the adjustment of the head. In Fig. 19, which illustrates the guide, the spring .9 and head J are indicated in dotted lines.

There is provided at the lower end of the guide H a side projection a circular on its under side, that serves as a cover and protection to the top portion of the chain-wheels L. WVhen the machine is operated by power, a sleeve V is placed on the left-hand end of shaft 6, and secured thereto by a setscrew a On the sleeve V and against the flange l X is placed a fly-wheel A, having about its central portion a series of apertures a, adapted to receive a series of pins a on the inner face of the hub a of the driving-pulley B. Against the outer face of the hub a of the pulley B is placed a plate 0, having in its inner face recesses (L in which is placed a circular or segmental spring a the crowningface to rest against the hub of the pulley, as shown in Fig. 13.

The plateO' is held against rotation on the sleeve by V-shaped ribs adapted to the V- shaped grooves a" in the hub of the plate. On the end of the sleeve is provided a screwthread on which is turned a nut (0 against the outside of the plate 0, by which the friction on the ends of the pulley-hub may be adjusted and regulated between the flange X and the springs a in the plate O, by which a desired amount of driving-power may be secured to drive the knives through the fodder and to allow them to stop and the wheels A and pulley B continue to rotate in case some hard substance should pass in with the fodder, and thus prevent violence or damage occurring to the knives, the knife-driving power being limited to the friction between the flange X and springs a on the wheel A and the hub of the pulley B.

To increase the cutting capacity of the machine, the width of the box and length of the knives are increased, and in that case I prefer a bent or V-shaped knife B, substantially as shown in Fig. 15, in which case I provide a central support E, secured to a cross-piece F. (See Fig. 18.)

G denotes a cast-metal knife-support having a central rib b to rest against and slide upon the face of the support E. In this form of construction it is desirable to have the central support E a distance from the knife G to allow the out fodder to fall unobstructed onto a carrier or other receptacle.

To provide against damage to the knife B or the stationary knife G, the support E has a hinged or yielding connection with the cross-piece F, comprising block W, having in its outer face a recess b circular in cross section, adapted to receive a circular projection I) on the side of the support E, through which is passed the bolt 19 by which the support is secured to the cross-bar F in a yielding rocking relation.

At the lower end of the support E is provided a spring 12 that rests against an adjustable slotted pin 11 secured to the bar F, as shown in Fig. 16. The object of this construction is to adjust the central portion of the knife similar the adjustment provided, and hereinbefore described, for adjusting the end portions of the movable knives to the stationary knife.

When it is desired to split the fodder before cutting, the cross-bar R, as shown in Fig. 1,.may be removed and a similar bar substituted, having splitting-knives similar to those shown on bar B, Fig. 15.

Having thus fully described the nature and object of my invention, what I claim is 1.
