Also a caster-wheel 's arranged to form loops 12, constituting entranceopenunder the center of the front bar 11 to supings, whereby the standing stalks of the corn port the front of the frame. Also rising from in parallel rows are brought into contact with the front bar 11 and connecting the same with the cutting devices. To the end portions 11 the cross-bar 18 at opposite sides of the en of the front bar are connected the draft aptrance -openings of the frame are vertical 5o plianccs, of which Ihave deemed it necessary outer and inner guards 33 and 311-, of which too the inner uprights 34 are extended rearwardly and connected to form a loop 35 of approximately V shape in plan. This loop constitutes a bracket, at the center of which is formed a point of attachment for the upper end of a cranked shaft 36, having inner or adjacent spindle portions, upon which are mounted sprocket- wheels 37 and 38, and outer offset or eccentric spindle portions, upon which are mounted sprocket- wheels 39 and 40, the sprocket- wheels 37 and 38 being connected by conveyer- chains 41 and 42 with similar upper and lower sprocket-wheels 43 on one of the inner upright spindles 21 and the sprocket-wheels 39 and being connected by upper and lower conveyer- chains 44 and 45 with upper and lower sprocket-wheels 46 on the other inner spindle 21. these conveyer-chains receive motion from the spindle 21, which in turn are actuated by the transverse counter-shaft 28, and said chains are provided with the usual spurs, which span the interval between rearwardlyconvergent inner and outer guide- rods 47 and 48, arranged in upper and lower pairs and combining to form ways which are flared at their front ends to receive the stalks in advance of the cutter disks or knives, and thus are parallel-sided to guide the stalks in their rearward passage to the shocking mechanism. The offset arrangement of the sprocket-wheels 37 to 40 provides for the operation of each pair of conveyer-chains without interfering with the other, and thus allows the stalks, which are severed by the two sets of knives, to be brought together at the point of convergence of the ways formed by said guide- rods 47 and 48. The innerguide-rods 47 are preferably connected at their rear ends, each rod being arranged in the horizontal plane of the conveyer-chain with which it cooperates; but. the rear ends of the outer guide-rods 48 are separated to form an outlet for the stalks and allow them to be fed upon the revoluble shocking table 49. This shocking table, which is preferably circular in plan, is fitted in a seat 50 in a tilting platform 51, a central spindle 52 being employed to connect the table with the platform. In addition to the rotary table 49 the shocking mechanism includes stationary and movable spreadingframes 53 and 54, of which the latter may be pivotally mounted upon the former in alinement with the axis of the table, as clearly shown in Fig. 5, the outer end of said movable frame having attachment, as at 55, to the table and being adapted, as hereinafter explained, to communicate rotary motion to said table. In the construction illustrated the fixed spreader-frame 58 is provided with a front upright 56, which rises from the tilting platform 51 and has a slotted connection, as at 57, with the rear ends of the adjacent outer guide-rods 48, such slotted connection being designed to allow the tilting of the platform 51 Without straining the guides of the conveying devices and at the same time Obviously fixed spreader frame are presserarms 60,

which when the movable spreader-frame is in its initial position, as indicated in dotted lines in Fig. 1, or adjacent to the plane of the fixed spreader-frame said presser-arms span the interval therebetween and are arranged across the path of stalks advanced by the conveying devices upon the shocking-table. The flexible tie, which may consist of wire or any other suitable material, is supplied from a reel 61, suitably mounted upon the stationary platform 16, and after passing through a guide 62 it is terminally attached to or engaged by the extremity of the carrier-arm, consisting of the upper member of said movable spreadei frame. Preferably the guide 62 is constructed with a clamping device, whereby backward or return movement of the tie is prevented, as when the tie is severed at a point in rear of the guide after the completion of a shock, and also of such a construction as to allow the tie to feed freely therefrom as the carrierarm 54 of said movable spreader-frame is advanced in the direction indicated by the arrow in Fig. 1.

In operation the spreader-frames are disposed in a forwardly-divergent relation to laterally bound a space which is in communication with the outlet of the conveyer devices, and as the severed stalks are fed rearwardly upon the table 49 they enter said space between the spreader-frames and, advancing toward the point of connection of said frames, tend to separate the same, and thus cause swinging movement of the frame 54 in the direction indicated by said arrow in Fig. 1, said separating or spreading action allowing greater space for the accommodation of the stalks, and the operation of spreading being continued until a shock is completed. The presser-arms 60, which are arranged in the path of the stalks as they enter the shocking mechanism, are pressed rearwardly; but their resilience serves to impart an outward pressure to the stalks, which assists in communicating motion to the movable spreader-frame, and thus increases the elficiency of the spreading action. The tie-wire being brought from the reel 61 through the guide 62 is passed over a cutter 69 and is then terminally attached to the carrier-arm 54. The tie-wire is maintained at all times outside of the forming shock, and thus serves to hold the stalks compactly between the spreader-frames. The advance of the movable spreader-frame continues until it reaches a position beyond the fixed portion of the frame, as shown in Fig. 6 of the drawings, carrying the wire around the stalks and crossing it at a point between the jaws of the tying mechanism, which will be presently described. This tying mechanism, as shown in the drawings, and particularly in Fig. 6, consists of a tie-spindle 63, slidably journaled in the bearing 6- supported by the standard and provided with a crank or handle 66, through the medium of which said spindle may be both reciprocated and rotated.

One end of the spindle has a fixed jaw 68, and pivoted to the spindle is a cooperating jaw 67, adapted for gripping action in connection with the fixed jaw. Between these jaws extends the tie-wire directly after passing over the cutter above mentioned, the wire playing through the jaws during the advance of the movable spreader-frame. As the movable spreader-frame passes these jaws it carries the end of the tie-wire between them, and thus makes a cross of the wire, the movable spreader-frame stopping at a point which brings this cross between the jaws and in a position to be gripped thereby.

In order to effect the gripping action of the jaws, the rear end of the jaw 07 is extended beyond its pivot and hangs below the spindle and has engaged therewith one end of the spring-plate 90, fixed to the under side of the spindle, and which spring tends to hold the jaws normally in an engaging position.

In order to open the jaws to grasp the crossed portion of the wire, a projection 91 is formed upon the upper surface of the pivoted jaw, and above its pivot and in the path of this projection as the spindle is reoiprocated lies a block 92, supported by a spring 93, fixed to the support of the bearing 6%. This block 92 is substantially triangular in form, and the tension of the spring 93 is such that as the spindle is moved forwardly the projection 91 will strike the block 92 and the pivoted jaw will be moved to an open position against the influence of the spring 90, and when the jaw has moved to the limit of its open position further outward movement of the spindle will cause the projection 91 to raise the block 92 and pass thereunder. At this time the open jaws are inclosing the crossed portions of the wire. When the projection 91 passes beyond the block 92, the jaws are brought together by the spring 90 and grip the wire with sufficient force to permit the twisting together of the ends of the wire. After the cross-wires have been gripped and before the twisting operation takes place the wire is out upon the knife adjacent to the holder 62. After the twisting operation has been performed the spindle is drawn rearwardly until the depending end of the pivoted jaw engages the front of the block, when this engagement will act to move the pivoted jaw to release the wire, the pivoted jaw having its depending portion projecting slightly rearwz'trdly, as shown at 90 in Fig. 7, to accomplish this result. 1

The tilting platform 51 ishiugedly mounted at its front edge, as shown at 70, upon the rear edge of. the fixed platform 16 and is adapted to swing between the vertical planes of the side bars 10 for depression independently of the main frame. For returning this tilting platform to its normal position after being depressed at its rear edge, as indicated in Fig. 3, and maintaining the same in its normal or horizontal position, as indicated in Fig. 2, I have illustrated a hand-lever 71 connected at its lower end with a stirrup 7 2, of which the transverse portion 7 3 extends under the platform, as shown in dotted lines in Fig. 1, and is journaled in bearing-blocks 73. (Shown in Fig. 8.) The stirrup has ofiset bearing portions 7 1, which are mounted upon the adja cent horizontal side bars 10 of the supporting frame, and with one of which offsets the lever 71 is directly connected. The leveris adapted to operate in connection with a notched or toothed segment 75, terminally fixed to the platform 51 and adapted to hold said lever at different points in its adjustment. This platform-operating device is unconnected with the platform-su pporting frame, the ofi'set bearing portions 7 1 being free to slide toward and from the axis of the ground-wheels upon the side bars 10 and the transverse supporting member 73 of the stirrup being pivoted to the under surface of the platform. It will be seen that when the bearing portions 74: of the platform-adjusting device are arranged in rear of the fulcrum-point of said platform the depression of the front or free end of the lever will impart upward pressure to the platform and that when the platform reaches the desired elevation the engagement of the lever with one of the notches or teeth of the segment will maintain it in that position. Preferably the lever is of a sufficiently yielding construction to adapt it to be engaged with or disengaged from the notches or teeth of the segment by a lateral swinging movement, the resilience of said lever normally holding it in position to engage the same.

In addition to the above-described mechanism, however, I have found it desirable to employ means for positively discharging a completed shock from the shocking-table, and in the construction illustrated said means consist of discharging-slides 76, mounted at opposite sides of the platform 51 upon guides 77 and 7 8, said slides being provided at their front ends with follower-arms 79, which extend inwardly over the surface of the platform and are normally arranged in advance of the shock. The guides 77 are secured to and extend longitudinally over the surface of the platform 51, while the guides 78 consist of arms extending rearwardly from the platform and terminating in upturned deflected or cam portions 80. Also the slides 76, of which the rear ends are mounted upon the guidearms 78, are provided with spurs S], which when the slides are in their normal positions are located adjacent to the rear edge of the platform 51 and are adapted to be forced into and engage the soil when the platform 51 is tilted or is released to drop with the weight of the superposed shock. After the engagement of these spurs with the soil the forward movement of the machine will cause the follower-arms 79 to rearwardly traverse the upper surface of the shocking-table, and thus drag the shock from its place upon said table and deposit it in an upright position upon the ground in rear of the machine. As the guide-eyes 82 at the rear ends of the slides 76 reach the cam portions 80 of the guidearms 78 they are elevated to Withdraw the spurs 81 from the soil, whereupon by means of the lever 71 the platform may be returned to its normal or elevated position, and this causes a forward inclination of the guidearms 78, which in turn causes the slides 76 to slip forward upon the guides until they reach their normal position. As shown in the drawings, the bar 79 passes under the frames 54.

It will be understood that in practice various changes in the form, proportion, size, and minor details of construction within the scope of the appended claims may be resorted to Without departing from the spirit or sacrificing any of the advantages of the invention.
