FREDERICK NISHWITZ, OF VILLIAMSB URG, NEW YORK.

liil P-RDVEli/INT IN GRAIN-HARVESTERS.

Specification forming part of Letters Patent No. 9,9755, dated August 30, 1853.

To all whom it may concern.-

Beit known that I, FEEDERIcK NIsHwITZ,

` of iVilliainsburg, in the county of Kings and State of New York, have invented certain new and useful Improvements in Beapers or Harvesting- Machines; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this speciiication, in which- Figure l is a front view of the machine in arrangement ot' cutters. and fingers, which will be hereinafter described; second, in the employment or use of flanged rollers, arranged, as will be hereinafter shown, for the purpose of throwing` or detaching the-grass or grain from the discharging ends ot' the belts.

To enable others skilled iu the art to make and use my invention, I will proceed to describe its construction and operation.

A represents a cylindrical shaft, on which is placed a series of cutters, c.. (See Figs. l and 3.) This shaft is placed at the front part of the machine or frame ot' the machine. (See Fig. 3.) Directly behind the shaft A is the front board or brace, B, ofthe frame. To the upper surface of this front board there is attached a series of iingers, l), which partially encircle the shaft. These fingers have an oblique position, as will be seen in Fig. l. They terminate in a point, as seen in Figs. 2 and 3. The obliquity of the fingers will be better understood by describing the upper edge of each blade of the fingers as projecting a little over the lower edge ot' the blade of the iinger adjoining it on the right side, supposing the eye to be directed at Fig. l. Through each finger there is a slot, c. (See Figs. l and 2 and dotted lines in Fig. 3.) These slots are for the purpose of allowing the cutters a to pass through as the shaft A rotates. The slots pass vertically entirely through the iin gers.

The cutters c proj ect'at ri ght angles from the shaft, and there are two that pass through each slot, or two to each finger, placed at opposite points upon the periphery of the shaft, as seen in Fig. 3. The cutters are not placed in line the whole length of the shaft, but are on the shaft spirally, as seen in Fig. l.

The operation ofthe cutters and fingers will be readily understood. Motion is communicated to the shaft A in any proper manner, and the cutters c, as the shaft A rotates, pass through the slots c in the fingers b. As the machine is moved along, the grass, grain, or whatever article is being cut passes between the fingers b, and the iingers having an oblique position, as before described-viz., the upper edge of each finger projecting a little over the lower edge of the finger adjoining it on the right sidethe grass or grain will be ben tas indicated by the red lines in Fig. l, and

consequently the cutters a., as they rotate, cut off the grass or grain with an oblique cut. The bending oi' the grass or grain causes it to be drawn tight, and the cutters consequently act upon it and cut it with the greatest ease and certainty.

By this improvement all shaking orjarring ofthe machineis avoided. There is no great friction, as is the case where the reciprocating saw-toothed cutters are used, nor is there any possibility of the cutters being clogged or choked, as is often the case in other reapingmachines.

G is an inclined bed placed directly back of the front board or brace, B. (See Figs. l and 3.) 0n this bed C there is an endless apron composed of a number of belts, D, passing over pulleys E E E and F F F. Three belts are represented in the drawings; but any proper number may be employed. The belts are provided with spikes d, and the grass or grain, as it is cut by the cutters, falls tipon these belts, the spikes d retaining the grass or grain upon the belts. The belts move in the direction indicated by the arrows. The pulleys FF Fare provided with iianges e-one on each side; or the pulleys F FF may be described as being deeply grooved, the belts iitting in the grooves. At the end of the bed C where the pulleys F F F are placed are curved guides GG G,which are so curved or bent as to cause the grass or grain to be turned as it descends upon them, the butt of the stalks or straw being toward the bed.

The operation of this improvement is eX,-

tremely simple. The grass or grain, as before stated, after being out, tells against the belts D, the spikes dreteining the grass orgrain upon the belts, and the belts moving in the direction of the arrows. As the belts pass around the pulleys F F F the flanges e throw the grass or grain free from the spikes, end it falls upon the curved guides Gr G G, and from thence to the ground, the guides, owing to their curvature, Causing the butt ofthe straw or grass to be toward the machine. (See red arrows 1n Fig. 1, which represent Jthe grain.)

The object of the spikes isA to properly retain or hold the grass or straw upon the belts while passing over the bell, and the object of the flanges is to throw off the grass or straw from the spikes and belts upon the guides when the grass or grain reaches the end of the bed to which the guides are attached.

The pulleys are hung upon shafts, and may have motion communicated. to them in any proper manner.

Having thus described the nature and operation of my invention, what I claim as new, and desire to secure by LettersPatent, is-

1. .The combination ofthe fingers b and eutters fr, or their equivalents, constructed, ar-

ranged, and operating in the manner und'for the purpose substantially as herein shown and Y
