machine piles the goods together in cylindrical, cone shaped or similarly formed hollow bodies; hereinafter referred to a's bundies or grain cylinders, and ejects them in this form, whichthey retainby'reason of twisting and compressing action imparted thereto. The bu ndles so formed are more readily dried than ordinary sheaves-,which is a great advantage when the harvesting takesplace in wet weather. 7

In the drawings a constructional embodirnent is shown, by way of example, of one forrnserving as a right-hand, cutting machine according to the invent on.

The cylinder 2 is concentric with and-con nected to thebuter running wheel 1. "On the inside of the outer running wheel 1S a toothed rim 3 fitted withsmall grooves 3'.

lntheseisrnall grooves 3 at for example three points, adjustable arms 5 of the frame 6 of themachine engage by the medium of the rollers 4; in this frame is secured the shaft or beam 7 The outer runningwheel 1 can rotate about the rollers at of the frame 6, and on drawing the machinealong by pulling the shaft rolls on the ground. The axle 8 of the inner cylin der 9 is arranged concentric'with cylinder 2 and rotatable in frame 6. Between the outer cylinder 2 and the inner cylinder 9 is a hollowspace 10 across the entire width of the running wheel, in which the grasses and cereals are brought, fastened together and formed into a cylindrical bundle. At the side, the frame 6 is provided with a support 1.1, which is carried at its support 11, arearranged transporting webs,

for example 14, 15, of cloth orthe like, these havingthe object of taking the reaped crop and conveying it to the annular cylindrical hollow space between the parts 2 and 9, which can be accomplished in varirus ways. The Webs may be said to'constittte a platform on to which the crops fall as they are cut by the device 12.

no form is shown in front view. plan and side View in Figs. 1, 2, and 3 respectively. The reanedcrop is conveyedfrom the cutting device 12 bya special endless web 15 to the main endless web 1 1 provided with studs to aid the transportation and. working transversely to the driving direction of the machine. I

I Since the cut straws are moved with their ears foremost, by the web15 in opposition to the driving direction of the machine; and by the endless web 14 transverse to the driving direction, a turning of the corn and a forwarding of the ears towards the hollow cylinder is effected. On the side away from the cutting device, the web l l is bounded by a further endless upright web 16, which it self moves as quick or quicker than the web l t. The tray-like slide 17, whose shape changes gradually from the flat ofthe surface of the horizontal transporting web 14 to the curvature'of the hol ow, cylinder, guides the'cut products from the platform tothe hollow cylinder. In the cylindrical hollow space 10 move the longitudinally mov able rams 18 (Figs; 1 and. 4-.) connected together more or less in dovetailed manner." These are guided by'means of the suitably formed arms 19, on a curved rail 20 fixed to the frame 6in such a way that at the delivery point of the tray-shaped slide 17 they are entirely withdrawn from the annular space, yet they are completely pushed into the said cylindrical space at the diametrically opposite point. Upon rotation of the working cylinder therams 18 are carried along therewith either by natural rubbing or in any convenient manner. It is therefore evident that the reapedcrops whichare con'veyedto the hollow space from the platform over the tray 17 are gradually compressed by the rams and pushed forward. The reaped crops in'this way strike against the cogs of the wheels 21, projecting through ill) the inner cylinder 9 into the hollow space 10, two or more of which wheels are arranged radially to the hollow cylinder. The cogs ot the wheels 21 engage with the endless screw 22, which is rotatably mounted on the axle 8, but can be coupled thereto by the couplings 23. At the beginning of the work the two wheels 21 and the at present uncoupled screw 22, stand still relative to the self-rotating cylinder; with increased feeding of the reaped crops and increased pressure the wheels 21 are turned'by the grain cylinder in the direction ot the arrows a, the endless screw is displaced along the axle 8 towards the left and coupled thereto through the coupling 23. The end less screw hereby receives the same speed of revolution as the axle 8. This is such that now the wheels 21 receive a rotation opposite to the direction oi? arrows (L, and with their cogs retard the forward movement oi the cylinder o t' grain in the hollow cylinder in the direction of arrows b. The rotating motion of the axle 8 is derived, as shown in Figs. 1 and 2, through the change wheels 24, 25, the spur wheels 26, 27, the worm wheels 28, 29, the pair of spur wheels 30. '1 and the pair of bevel wheels 33 "a shaft 35 which is coupled and uncoupled by means of the coupling 34 and driven by cog wheel 36 mounted thereon from the toothed rim 3 of the track wheel 1. By varying the wheels of the changegear 24, 25, a change in speed of the endless screw 22 and hence ot the cog wheels 21 is obtained, so that 1t is possible to adjust the forward velocity of the cylinder of grain according to the strength and quality of the straw, audits degree of dampness in any given working conditions.

The inner cylinder 9 extends beyond the topmost ram 18 a distance y which is approximately equal to the desired length of the finished bundle, referred to as the grain cylinder. The outer cylinder 2 projects beyond the inner cylinder 9 a further distance in which is slightly greater than the distance 3 and is cut away to provide an ejection aperture 53. A cylindrical sleeve 37 is rotatably mounted upon the outer end of the cylinder 2 and has an aperture 52 there n, which from time to time comes into registration with the aperture 53 to allow the grain cylinders to be.discharged from the machine as they are completed. The.

sleeve 37 will rotate together with cylinder 2 by reason of the friction therebetween, but its rotation is adapted to be arrested by a projection 42 thereon coming against arm 41 of a vertical spindle 40 journaled in the frame 39 which is rigidly secured to frame Got the machine. The arm 41 is normally held by means of a spring 45 in a position out of the path of abutment 42 so that the sleeve 37 is free to rotate. A roller 38 is carried by an arm secured to the upper end of spindle 40, and projects somewhat within the cylinder 2 and in line with the annular space 10. This arrangement results in that as the grain cylinder formed in space 10 is advanced into the discharge end of cylinder 2, it presses against the buffer roller 38, turns the spindle 40 against the action of spring 45, thereby moves the arm 41 into the path of abutment 42 so that the sleeve 37 is arrested with its aperture 52 directed downwards and rearwards, and as aperture 53 in cylinder 2 comes into re istration, a grain cylinder of length a: will fall by its own weight out on to the field, as hereinal'ter explained. Actuation of the butter roller 38 also interrupts the feed of the conveyer mechanism by disengaging the coupling 34 by means of draw-bar44 pivoted to a. crank arm 43 secured upon the lower end olt' spindle 40. i

The division of one grain cylinder from the tollowing one is effected according to the preterred method in this Way. In operation the machine is first worked until a cylinder of grain is formed extending from the rams 18 to the butter roller 38, pushing back the latter and thus causing the clutclr34 to be disengaged and interrupt the advance of fresh material to theannular space 10, and at the same time arresting the sleeve 37 as above described so that the aperture 53 comes into registration with the aperture 52. This long grain cylinder is then cut into two approximately at the position indicateo by arrows .2, by hand or in any other convenient manner and the portion thus severed will fall out. Now during the time that one grain cylinder is undergoing ejection, which corresponds approximately to one revolution of the cylinder 2, the rams 18 act upon the rear end of the following grain cylinder to compress same without additional material being added. So, when the buffer roller 38 is allowed to be brought back by its spring 45 into the normal position incidentally the sleeve 37 is released, thecoupling 34 re-engaged, more material isfed forward to the rams by the conveyor, and

the formation of another grain cylinder is commenced. Thus, by interrupting the conveyor mechanism. a division is made between consecutive grain cylinders which suffices to enable said cylinders to fall out, one by one, as they reach the ends of cylinder 2 and cause the exit apertures 52, 53 to come into appropriate registering position.

The separation of the firstformed grain cylinder by cutting as described above might in some cases be effected alternatively by operating the bulfer roller mechanism manually when a m is first formed.

The treatment which the stalks receive grain cylinder of length within the annular space 2 enables the finished bundles to retain their shape without additional binding means as is necessary for ordinary sheaves. The bundles will lie on the ground on their sides until stood on end manually 01' otherwise when they will dry much more readily than ordinary sheavesby reasonof their form, particularly if raised somewhat on one side so that a through passage for air is provided.

It is obvious that the machine above de scribed. admits of various modifications without departing from the scope or spirit of the invention. For example the platform can also be constructed according to Figs. 6 and 7, where two endless webs work behind each other in the same direction; the web 46 moves quicker than web 47, so that here also the stalks are turned and conveyed in the proper direction to the tray and so to the hollow cylinder.

In Figs. 8 and 9 a further embodiment of the platform is shown. There are two endless webs 48 and 49 disposed one over the other between which the reaped crops are taken and conveyed to the slide and so to the hollow cylinder. The cut goods fall first on the upper web 48 which carries them outwardly. At '50 an interchangeable plate 51 of dimensions according to the length of the grain is disposed between the cut stalks and the smaller endless web 49. i The cared .ends of the stalks are seized while the straw ends fall on the polished sheet 51. Here also the forwarding of the cared ends as against the straw ends is effected and the reaped crops are conveyed in appropriate position between the webs to the slide and so to the hollow cylinder.

The machine can be adapted for driving through narrow and small ways in known manner by means of displaceable wheels and for driving longitudinally and also so constructed that the platform can be closed up.
