IMPROVEMENT lN REAPlNG-MACHINES.

Specification forming part of Letters Patent No. 5,189, dated July 10, 1847.

To all whom it may concern:

Be it known that I, WILLIAM F. KErcIIUM,

' specification.

The nature of myinvention consists in an endless-chain cutter for cuttin g grain and grass, and the application of it in such a way as will 'cause it to run around pulleys with the back of the cutter against them, (the pulleys are fixed on the rack-piece of proper length for the width of the swath to be cut,) with the cut-' ter passing round the pulleys, the cutter being covered all but the edge which comes in contact with the grain or grass.

To enable others skilled in the art to make and use myinvention,Iwill proceed to describe its construction and operation. I

I make the endless belt of cutters, as seen at A, ofiron and steel segments or pieces about three or four inches long, and I connect them together by lapping the longest pieces on the top of the short pieces, (seen at B.) The ends of the longest pieces meet in the center of the short pieces, and the short pieces are riveted fast with two rivets at one end, and the other end is riveted to the other long piece with one rivet, which is the joint or pivot on which the pieces work or turn. The inner corner of the longest pieces are rounded off, so that the belt may bendor work around the pulleys, (seen ate 0.) The belt of cutters is placed on the rack-piece D flatwise and around the pulleys edgewise, or, rather, the back part of the cutter is against the pulleys and the cutting-edge projecting from them between the rack-teeth. The rackteeth are fastened to the rack under the belt of cutters, and are seen at E E, projecting out in front of the cutting-edge. Thevinner corners of the longest pieces or segments of the belt of cutters being rounded allows the belt to yield and work around the pulleys edgewise. The pulley nearest the driving-wheel is propelled by cogs on the shaft F, which shaft is propelled by the main cog-wheel, (seen at N.) The other pulley yields to the uneven surface of the belt by a spring, G, bearing against its boxing. 4

The crooked arm or coupling-piece H, which connects the rack-pieceD to the cast-iron frame L, I make of cast-ironand fasten one end of it to the frame at or near the center of the driving-wheel K. The other end has asort of open mortise in'it, in which I fasten the rack-piece D with bolts, (seen at J J which rack-piece may be made of wood or wrought-iron. By

connecting the rack-piece to the crooked coupling-piece H and the crooked coupling-piece I,

me to rake the grain ofi the platform L on oneside out of the track of the machine. I brace the rack to the frame-with a wrought-iron brace from the front part of the frame, (seen at M.)

What I claim as my invention, and desire to secure by Letters Patent, is-

l. The endless-chain cutter, in combination with the pulleys and rack-teeth for cutting grain and grass, as above described.

2, The crooked arm or coupling-piece, in connection and combination with the rackvpiece and frame, as above set forth, for the purposes therein stated.

WILLIAM F. KETGHUM.
