Description
J. G. PERRY. Straw Cutter.
Patented March 24. 1863.
n m m f UNITED STATES PATENT ()FFICE.
JONN G. PERRY, OF SOUTH KINGSTOWN, RHODE ISLAND.
IMPROVEMENT IN STRAW-CUTTERS.
Specification forming part of Letters Patent No. 37,974, dated March 24,1863.
To all whom it may concern:
Be it known that I, JoHN G. PERRY, of South Kingstown, in the county Washington, in the State of Rhode Island, have invented an Improvement in Machines for Cutting Hay,
Straw, or Fodder; and I do hereby declare that the following is a full and correct description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.
Similarletters in all the figures refer to the same parts.
Figure 1 is a perspective view of the haycutter. Fig. 2 is a back elevation. Figs. 3 and 4 are sections of the cylinders, showing the knives.
The frame work of my improved hay-cutter is made in the usual manner-that is, a horizontal tapering trough, B, to hold the material to be cut, is supported under the middle by a standard, It, secured to a base-frame, N, and at one end by two standards, A A, upon which is fastened the cutting apparatus, which consists of two rolls, 0 E, placed between the standards and turning in hearings on them, these bearings being so arranged that those on one roll, being movable, can be set toward the other by means of the two screws t t. One of these rolls, 0, is made of some firm metal or mineral or other suitable material, and is made smooth and round. The other roll, E. is made with one or more flanges or rings, (see Fig. 5,) having knives S S secured to their periphery, lying lengthwise of the roll and flat, nearly in a line with the circumference or their line of motion when the roll is turned. (See Fig. 3.)
Fig. 4 shows how the knives may be put on the sides of the flanges and bent nearly at right angles, so as to answer the same purpose.
H L are gear wheels, secured to the ends of the rolls to govern their relative motions while running, in sharpening the knives-- that is, to cause the knife-roll to turn faster than the other one, that the knives may rub against it, and thus sharpen them. Their use is not so essential to the operation of cutting.
:0 is a balance-wheel, which is fastened on the shaft of one of the rolls, and into which the handle a is inserted, which serves the purpose of a crank to turn the rolls by.
It will be seen by reference to Fig. 3 that the principle of cutting obtained in this machine is entirely different from what it is in those using radial knives, which out directly toward and into the other roll, as in the machine'using a hide roll, in which case there is no tendency to sharpen the knives by use, but, on the contrary, to dull them, when to sharpen them they must be taken ott' of the roll.
In my machine the knives cutting by the roll tends to sharpen them by whctting them upon their outsides.
The mode of operating the machine is as follows: A proper quantity of hay or other material to be cutis laid in the trough B in contact with the rolls, when, the wheel a: being turned, it is drawn in between the rolls and out off by the knives S S.
Having thus described my improved haycutter, I claim-- The combination of the smooth cylinder 0 with the cylinder E, having a knife or knives arranged as herein described, and for the purposes set "forth.
