lMPROVED vARRANGEMENT 0F CUTTERS IN GRAIN AND GRASS HRVESTER.

Specilicatin forming` part of Letters Patent No. 7.48 I'. dated July 2, lli-50.

lo all 'whom 'it may concern:

Be' it known that l, JACOB PEIRsON,of Wiliningt.on,in the county of Newcastle and State of Delaware, have invented new and useful Improvements in Mowing and Reaping Machines; and l do hereby declare the following` 4to be a full, clear, and exact description of the delivery of the cut grain in gavels.

In the annexed drawings similar letters refer to corresponding parts in all the figures.

Figure l is a top or birt s-eye view of the machine. Fig. 2 is a rear elevation. Fig. 3V is an elevation ot' the rightsideof themachine. Fig. 4 is a top view of a portion of the cutterbelt and its appurtenances. Fig. 5 is a trailsverse section of the same.

rlhe frame a, pole b, running-wheel c, driving-wheel d, bevel-gearing e f, endless delivery' apron g do not di-er materially from mechan ism heretofore employed in this connection.

To the hindermost cross-rail, a', of the frame is journaled the rear extremity of the pinionshaft h., which projects back of the rail a snciently to carry 'a couple of pulleys, ij, which actnate the cutting and delivery apparatus,in the manner hereinafter described.

Extending upward from the rear end of the frame are two ironvcolnmns, lc, and to the top of these js bolted a rail, l, which extends horizontally some distance to the rightof the posts.

vParallel with and directly under this rail l,

and but a short distance above the ground ,is another rail, m, whose right extremity is supported and stayed by a post, a, connecting` it with the rail l. The middle and, left extremity of the rail m are supported by iron hangers o o, extending downward and rearward from the under side ofthe frame to which they are bolted.

Pivoted at its lower extremity to the rail m, near its right end, and confined above within agroove, p, is a bar, q, from which project the journal-pins of two guide or carrying pulleys,

r r', around which and the pulley t' is passed a continuous belt of leather, s, armed ateqnal distances with cutters t, each heilig attached to the belt by a cou ple of bolts. The belt, having been placed upon the pulleys, is made tant by means of the screw -bolt u, which draws back the upper end ofthe pivoted bar q in the ar'c of a circle, at the same time drawing back the pulley i. Thesecuttersin theirlower position rest upon a couple of iron bars, 1 2, fastened to the top of the rail m at such a distance apart as to' allow of the passage of the bolt-heads of the cutters between them, and these bolt-heads by this means serve to maintain the cutters in a direct course while lin action or parallel to the ways.

A metallic plate, v, is fastened to the back of the rail'm, rises vertically, is then heut at right angles and extends horizontally,` is then turned down vertically, being extended over the rail, and forming a sheath or cover from the grain, and valsoan attachmenttbrthc pointed guards w, which are placed soniewhat closer.

together than the cutters ton the endless belts.

From the rail m also project the journal-pins A of two rollers, X, upon which lthe endless delivery-apron gis stretched. One of these rollers has a pulley, w', which communicates by a cord, c, with the pulleyj on the pinion-axle h, as aforesaid.

The cutters maybe sharpened on both edges, and be reversed on the belt when one edge is worn out. f

The operation is as follows: The machine being advanced in the usual way by horses being attached to the whifletree E, the, rotation f the driving-wheel d will communicate motion through the gearing cfto the pulleys ij, and thence .to the endless belt s and apron g by means of the crossed band c, and the pointed 'guards w (which areinade. in the ns'ual manner) will collect the grain, which will be rapidly severed by the cutters t, and falling over onto the apron g is by it carried leftward in. I vthe direction of the arrow 3 until it reaches the rake or arrester z, which-being elevated at proper intervals by the driver, the grain is deposited by gavels at the left-hand extremity of the apron.

As is usual in this class ofreaping-machines, the team walks alongside the standing crop, keeping it uniformly to the-right. ylhe armto which the rake-handle is alxed is pivoted to tbe rear part of the frame in any convenient position, so as to bring the points of the raketeeth near the surface of the revolving endless apron, to arrest the motion of tlie struwthereou until 4e'sul'icient quantity s collected to form a gavel. This rake may be raised and lowered by-meansl of a. cord and pulley, or a lever, or by any convenient means. There may also be a sheet-iron guard secured to the post n land' rail m,

meetingat a point in front 0f the teeth to divide the grain and shield the lowercarryiug-pulley, as shown by the dotted lines I in Fig. l`

Having thus fully described the nature "of my improvements in mowing and reaping manul, and desire to secure by Letters Patent,

Thearrangement, substantiallyas herein described and represented, of cutters bolted to an endless belt, s, revolving in a, vertical orbit, and vmoving on a rail, m, guarded and disposed after the manner described.

In testimony whereof l have hereunto signed my-.name before two subscribing Witnesses.

JACOB PEIRSON. Witnesses:
