SPECIFICATION forming part of Letters Patent No. 593,449, dated November 9, 1897.

Application filed September 1,1896. Serial No. 604,583. (No model.)

To all whom it may concern:

Be it kn own that I, lVIIHAIL ALEXANDRESCU, a subject of the King of Roumania, residing at Bucharest, in the Kingdom of Roumania, have invented new and useful Improvements in Reaping-Machines, of which the following is a specification.

This invention relates to a reaping-machine which is pushed by a draft-animal along the field to be reaped.

The new machine is illustrated in the accompanying drawings, in Figure 1 in side elevation, and in Fig. 2 in plan.

The improvements in this machine relate more particularly to an apparatus which serves to grasp the corn to be cut, to bend it down, and then to convey it to the knives.

The framing a of the machine rests on the ground-wheel axle Z), on which are mounted the ground-wheels c. From this axle the cutter-bar (Z has to-and-fro motion imparted to it in the usual manner by means of toothed wheels, crank-shaft, &c. The cutter-bar consists, as usual, of a number of triangular knives sliding in slots in the fingers 6, so as to cut the corn that enters between said fingers e. The corn then falls upon an endless apron p, which passes over the rollers pp. The rollers p p are rotated from the ground-wheel axle, so as to cause the apron p to travel continually in one and the same direction. The corn falling upon the apron p is conveyed onto a rack q, where it collects until it falls onto the ground when the rack has moved inward. The rack q rotates about the axis q, and when the rack moves inward the several teeth or bars of the rack pass under the rollers p or the apron 1).

The apparatus for the purpose of bending the corn downward consists of the two struts f, which are situated above the knife-beam (Z and are connected together at top by means of a transverse shaftg, which is journaled in the struts f and carries the two side arms h. The struts f also carry at their upper end two arms 2' i, which are not rotatable, but are in fixed relation to the struts J".

On the ground-wheel axle there is arranged a cross-shaped arrangement of arms 70, which, as shown in Fig. 1, consists of four arms which are bent over at their outer ends. On rotating the toothed Wheel the arms act upon a tappet Z, which is fixed 'to thewheel Z, that is mounted on the frame a. Each of the arms is moving in the direction of the arrow serves to rotate the wheel Z through one-quarter of a revolution, after which the said arms slide off along the tappet Z. To the wheel Z there is affixed at Z a cord m, which passes over the guide-pulleys n to a ring 0 on the arms 2', to which the cord is secured. WVhen the arms 7e actuate the wheel Z, the cord is partly wound upon the said wheel with the result of rocking the arms h downwardly into the position 72. (Shown in dotted lines in Fig. 1.) To the ends of the arms 2' there are attached ropes T, which pass through rings to the front ends of the arm h and thence to guide-pulleys f on the struts f. From these guide-pulleys f the ropes pass down and carry weights .9. Between the two arms h the two ropes r are connected by means of a transverse rope 25. As the ends of the ropes are connected to the arms i,when the arms it move down the Weights s are raised and the transverse connection 25 moves into the position i. (Shown in Fig. 2.) This transverse connection 25' engages with the corn and bends it down toward the knifebeam, where, after it has been cut off, it falls onto the apron p. As soon as an arm is slips off the tappet Z the wheel Z revolves back into its initial position, while at the same time the weights .9 move down and thereby cause the arms h to reassume their raised position.

As the machine is pushed forward by the draft-animal (see Fig. 1) the arms 71. with the cross-rope t are given alternately an up-anddown motion, and thus the corn to be cut is continually being carried toward the knifebeam.

The aforementioned rack q moves with its outer beam, which carries a ring g on its end, along a curved or bent piece g This bent piece is provided at its rear end with a handle g which serves to enable the operator to guide the machine.

The cutting apparatus is driven by a link CZ, reciprocated through the medium of a crank carried on a shaft (Z that runs parallel with the frame of the machine beneath the apron p and is driven by a bevel-gear 0Z meshing with a bevel-pinion (Z on the shaft CF, and in turn carried on a counter-shaft (Z The counter-shaft 6Z5 is journaled in the frame a and has a sprocket-wheel 19 over which the chain 5 passes to a spur-sprocket b, fixed on the axle b of the wheels 0. The shaft d also drives the apron 19 through the medium of gears 19 and 19 respectively fixed on the shaft 61 and one of the rollers p and adapted to be connected by a chain passing between them. The two rollers 19 are also connected to each other by means of a chain 19 passing over gears 10 and p respectively fixed to the rollers.

I claim- 1. The herein-described means for pressing down grain or the like to be cut, consisting of the struts f, arms 2', shaft g, carrying the arms h, wheel Z rocked by the arms is, a connection between the wheel Z and the arms h, for rocking the latter, a flexible strand connected with the arms 2', and passing across between the arms h, and weights 8 acting on said strand, all in combination, substantially as described. I

2. In apparatus for pressing grain or the like downward, the combination of a frame mounted to rock, a flexible strand extending across the frame, means for rocking the frame, and means for shifting the strand outward and inward on the frame, substantially as described.

3. In apparatus for pressing grain or the like downward to be cut, the combination of a frame mounted to rock, a pulley or reel, a flexible connection leading from said frame to the pulley or reel, means for imparting motion to the said pulley or reel, and a weight acting on the rocking frame in opposition to the movement imparted from the said pulley or reel, substantially as described.

4. The combination with a harvester, of rigidly-supported struts running outward therefrom, a frame pivoted to swing between the struts, flexible connections respectively attached to the struts and run over the frame, weights for the flexible connections whereby to raise the frame, a second flexible connection in connection with the frame, a reel to which the second flexible connection is attached, and means for oscillating the reel.

5. In aharvester, the combination of a frame pivoted to the harvester and capable of swinging back and forth in a regular are from a point above the grain to a point adjacent to the cutting apparatus, and means for operating the frame, such means being carried on the harvester and driven by the mechanism thereof.

6. The combination with a harvester, of a same toward the cutting apparatus, a flexible connection attached to the frame, means for alternately drawing and releasing the flexible connection, and a weight having connection with the frame and serving to oppose the said flexible connection.
