IMPROVEMENT IN MACHINES FOR CUTTING HEMP.

Specification forming part oi Letters Patent No. 7,568; dated August 20, 185.0; Reissue No. l ,200, dated June 18,-186l.

To all whom it may concern:

Be it known that JOHN LOCKE HARDE- MAN, of Saline county, near Arrow Rock, and

- Figure 6, is straight and sharp onthei r cuttingedges, two and a half inches wide for one-half their length, then sloped toward their cuttingedges, leaving their other ends half an inch. wide and one-eighth of an inch thick onmthen backs. From their back at their center is cut a semicircle, a, Fig. 6, Plate 2, to admit 'of the screw b, Fig. 1, Plate 2, passing between the backs of the blades 0 c, Fig. 1, Plate 2, when placed upon the arni d, Fig. 1, Plate 2, in which place they occupy a space of eight inches on the arm and terminate together in a point. The armd, Fig. 1, Plate 2, is constructed of cast-iron, four feet long, fourinches wide, and two inches thick, having a rabbet, e,.Fi g. 1, Plate 2,-cut from the upper and back corner, twoinches wideand three-fourths of an inch Plate 2, to receive the blades 0 c, Fig. 1, Plate 2, which projecting points are t rou ghed or channeled, so as to "form, with the cap 9, Fig. 1, Plate 2, and Fig. 8, Plate 2, jaws, by which the blades 0 0, Fig.1, Plate 2 are firmly held in their position at an angle of about forty degrees from a level, which is the position of blades are in pairs, back to back, in a V form. That one of said points which is nearest 'to the main frame 0 is secured thereto, as clearly illustrated. At each end of the arm there are singleblades h 71., Fig. 1, Plate 2, right and left. he arm is so placed as to be at right angles with the track of the horses, and exfourfeet into the standinghemp, &c.,

It is also extended two and a half feet on the left hand in an upward direction, d (3, Plate 5, across and into the framework P P, Plate 5, to'which it is attached, and is a plain bar without rabbet or points. The caps 9, Fig. 1, Plate 2, and Plate 2, Figs. 7 and S, are of castdron, formed so as to confine the blades c c, Fig. 1, Plate 2, by being pressed firmly down upon them, and fastened by screws b, Fig. 1, Plate 2, the angle of the sides 1' i, Plate 2, Figs. 1 and 8, corresponding to the sides of the projecting points f, Plate 2, Fig. 1, the two forming-jaws in which the blades are held as in a vise.

The remainder of the cleaner or cutter is a shank or handle four inches long, having a hole through the end where it is attached to the projecting points I, Plate 2, Fig. 1, of the bar k, Plate 2, Fig. 1. There is also a hole through the widest part through which passes the screw 11., Plate 2, Fig. 1, into the arm d, Plate2, Fig. 1, and on which it works like a n'ioviugshear-blade over the junction of the stationary blades e, Plate 2, Fig. 6, which form the lower' part of the shears. ,To the right-hand end of the arm is fastenened by rivet-s c c '0, Plate 1, the separat-or, Plate 1, one

The frame-work is made ofsolid oak -tin1- ck, and joined .as in the on a scale of two inches to t Plate 4,which is one and onethird inch to the foot. The machine is drawn by two horses tandem, the leading horse being attached to a onnecting the points of the shafts in front of thebreast of the other horse, cted as to equalize the resistance of the arm or finger-bar, which is all at one side thereof, by means of a m the, driving-wheel being placed as far as pos sible' to the left for the same purpose.

' It will be observed that the above-described invention or improvements contain some of the essential elementsofthe best mowing-ma. chines now in be seen by refe useas, for instance, it will, reuce'to Plate 1 of the drawiugs, that the invention made the subject of this division has most of the main groundwheel'framefa-r above the ground, and also' that the part of it which comes near the ground rst projecting Point, or that one or cutters of a crank and' pitman;'a is but' four inches wide,
