Specification of Letters PatentNo. 33,1 19,,dated A,ug1 1st2Q, 1861.

To} all whom z'ijmayconcern:

Be it known that I, JorrN R. Wnrrrnnronn,

of Ghicopee Falls, in the county of Hampden and Commonwealth of Massachusetts,

chine is represented by a side sectional View.

In said drawing letter A, is the common hide roll for cutting against.

B, is the cylinder for holding the knives, usually made of iron; 0, the arbor or center in hide roll.

I), D, D, are the knives for cutting; E

side board to the hopper; F top board to the mouth piece of the hopper; Gr, movable spring board in the mouth of the hopper.

H, is the spring which presses the block I, against the spring board G.

J, J, J, is the wood frame, the cross lines 7 upon some parts showing where the machine is cut to show it in sections; K, the spring which keeps the hide roll from pressing too hard upon the cylinder of knives below.

L is the set screw which keeps the roll down upon the edge of the knives below, so that any feed may be cut that is brought between them.

M, M, M, is the iron frame which holds the roll, knives, &c.

N represents the position of the balance wheel.

The nature of my invention consists mainly in the use of common hide roll and cylinder of knives; using therewith a less number of knives than can be used with said roll and cylinder alone; and then combining with said roll and knives a compressible mouth to the hopper, the advantages of which I will hereafter describe.

The roll A is made of rawhide in the usual wayviz., it is first cut into circles with a hole in their centers, and then forced upon an arbor by a powerful press until they are solid, and then held firm at each end and when turned off in a lathe a smooth hard surface is left to out against. The knives in the cylinder B, are held by forcing them into slots made in the cylinder, but may be held by screws or other ways. These knives are so arranged that in their revolution their edges will merely touch the roll above for the purpose of cutting anything that may be brought between them. This roll turns only when acted upon by the knives below,

to, w hich cylinder of knives. the crank is, apphed,

The mouth of; the hopper through which the feed passes ismade compressible, or variable, but is not new independent of its, com binations. The sides of the hopper form each end, a stationary board F forms the top, with the board G at the bottom, which board is hinged at one end as seen, and acted upon by the spring H, and block I, which press against it. This spring runs back over the standard which supports the hop per, and is held between the standard and hopper, and is allowed to slide forward and back according to the pressure desired upon the spring board G, and the feed in the mouth of the hopper. WVhen pressed back as represented a hard pressure is produced; but when entirely forward very little or none.

In cutting some kinds of feed as hay, when considerable length is desired, but little pressure is needed; but when it is desired to cut stalks, the number of knives usually used prevents their being cut to advantage, the knives being so near together the stalks are crowded in between them and clog it up so that it cuts slow and hard, very few can be cut at once; but by dispensing with all but two or three knives there is no chance for clogging between them and about three times as large a body of feed can be cut very easy. Then this compressible mouth is absolutelynecessary to prevent the stalks from coming back from the place or point of cutting, so that the neXt revolving knife will take hold of it, and when it does take hold of it to prevent it being drawn too easily and thus too far forward, causing it to be out too long. It gives a regularity of cut which otherwise cannot be obtained also making it self-feeding.

If the knives upon the cylinder B are near enough together so that the knives behind shall pinch the feed to hold it before the one in front has cut it off, the feed and more especially stalks will crowd and clog between them. Then to make an effectual stalk cutter from the common hide roll outter it is necessary to use a less number of knives than has heretofore been used, and if so it is necessary to combine with it a comlent, to hold the feed until the next revolving knife shall reachit, draw it forward and cut it off. The hide roll cutter has heretofore been considered not valuable for stalks for the reason above named, it is not a selffeeder without at least five knives upon the cylinder which are too many for stalks.

Although a less number of knives upon the cylinder does not produce as many cuts at a turn of the crank, yet, this deficiency is more than made up by the larger body of feed it will cut at once. This compressible mouth Will so regulate and hold the feed back and compress it, that one knife will out twice as fine as twelve or fourteen in the usual way for fine cuts; and three knives will cut as fast as fourteen, because of the larger body of feed it will cut at once. It is intended to use in this machine from one to 7 three knives. The roll can also be "made smaller as a less number of knives cut upon it to wear 1t out, thus a larger machlne can be furnished for the same price or a machine of the same size at a less price.

I claim as new and desire to secure by Letters Patent is The compressible mouth ofthe hopper in combination with the hide roll Aor-its 7 equivalent and the cylinder of knives B, substantially as and for the purpose specified WVitnesses:
