HENRY W. JOHNSON, OF MOPHERSON, KANSAS- SHO'CKER.

SPECIFICATION forming part of Letters Itlatent No. 739,084, dated September 1 5, 1903.

Application filed March 5, 1903.

To all whom it may concern:

Be it known that I, HENRY W. JOHNSON, a citizen of the United States, residing at Mo- Pherson, in the county of McPherson, State of Kansas, have invented certain new and useful Improvements in Shockers; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to shockers for harvesting-machines; and ithas for its object to provide an attachment which may be secured to the main or binder frame in position to receive the bundles from the table and which mechanism or attachment after a predetermined number of bundles have been contributed thereto will be automatically operated to discharge the bundles in upright positions and set them upon the ground in the form of a shock, the part-s of the mechanism then returning to their original positions to receive other bundles. 1

Other objects and advantages of the invention will be understood from the following description and include the provision of structural details to insure proper sequence of the steps of the operation.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the sev-' eral views, Figure 1 is a perspective View of the machine with the parts thereof in position to receive the bundles. Fig. 2 is a side elevation of the attachment with the parts in position'to receive the bundles. Fig. 3 is a section on line 3 3 of Fig. 4 on a smaller scale. Fig. 4 is a plan view of the attachment in its final position of discharging the shock. Fig.

5 is an elevation showing the mechanism shown at the left of Fig. 2 and with the latchfinger in engaging position. Fig. 6 is a rear elevation of -a part of the machine, showing the means for disengaging the latch.

Referring now to the drawings, the present Sh0Ck6l,WhlCl1 is designed for attachment to the main frame of a harvester and binder, comprises a frame including the longitudinal sills 10 and 11, arranged in parallel relation and connected at their forward ends by the cross-piece 12, the sill 10 having brackets 13 for attachment to the main frame 15 of the Serial; No. 146,404. (No model harvester and binder, while the sill 11 is provided with a supporting-wheel 14. It will be noted that the rear end of the frame of the attachment is open. At the forward end of the frame of the attachment is mounted an oscillatory transverse shaft 16, having rearwardly-directed fingers 17, which lie between the sills l0 and 11, and the rear or free ends of which fingers are designed to rise and fall as the shaft 16 oscillates. When the extremities of the fingers 17 move downwardly to their limit, the fingers slant, so that the bundles which are discharged onto the fingers from the table of the main frame may be readily moved from thefingers and at the same time swung into erect positions.

To move a numberof bundles simultaneously from the fingers 17 and deposit them in the form of a shock upon the ground, the following mechanism is provided: A head 18in the form of a plate is provided, the ends of the head being slotted, as shown at 19 and 20, to receive the stems 21 and 22 of the bundle-holding arms ofthe mechanism, these arms being shown at 23 and 24 and including cross-pieces 25 and 26 at the ends of the stems, and from which cross-pieces extend the .pairs of curved members, as illustrated, the arms being so positioned with relation to the head that when the plate is in horizontal position the curved members of each arm will lie one above the other and when the head is in vertical position the curved members of one arm will lie vertically above the curved members of the other arm. As illustrated, the stems of the bundle-holding arms are pivotally mounted in the end slots of the head, so that the opposite ends of the arms may be moved toward and away from each other to gripor release the bundles. Normally the head is in vertical position wit-h the arm 23 below the arm 24 and in close relation to the extremity of the fingers 17, so that the bundles deposited upon the fingers from the binder-frame will lie with their heads upon the arm 23, and if the arms be then caused to grip the bundles and the head be rotated to carry the arm 2t forwardly of the machine and the arm 23 rearwardly'the bundles will be gradually moved into erect position and ofi from the rear ends of the fingers. The bundles may be then lowered to the ground and the arms operated to release them and then raised above the tops of the bundles and moved to their former positions as the machine progresses.

To hold the arm 23 against downward pivotal movement when in position to receive the bundles, the stem 21 is provided with a finger 25, which projects beyond the outer face of the head 18, and in the path of movement in one direction of this finger is alatch or stop 26', which is pivoted to the rear face of the head 18 and isheld normally and yieldably in active position by meansof the helical spring 28, which encircles the rod 29, attached to the pivoted latch, and rests with its ends against the latch and the eye 30, through which the rod is slidably passed. When the latch or stop is raised against the action of this helical spring, it passes from the path of the finger 25', so that the arm 23 may swing in a direction away from the arm 24 to release the shock, as hereinafter described. The arm 23 is held normally and yieldably against movement in a direction away from the arm 24 by means of the helical spring 31, which is disposed between the inner end of the slot containing the stem and the adjacent face of the stem, the spring being attached at both ends and having such strength that it will return the arm 23 to its normal position when the shock has been released.

To hold the arm 24 spaced to the maximum degree from the arm 23 when the latter is in horizontal position, the stem 22 of the arm 24 has a rearwardly-directed lug 2, which projects into the path of movement of the cam 33 on the rod 34, which is pivoted to one end of the head 18 and through the medium of which said head is oscillated on the shaft 35, which is slid-ably mounted in the diagonal slot 36 in the outer side of the frame of the attachment. The rod 34 is connected to the crank -arm 37 on the oscillatory shaft 38, mounted at the forward end of the frame of the attachment and which is oscillated at suitable intervals from the binder mechanism. As the rod 34 moves or swingsthe head 18 into vertical position the cam 33 is carried into engagement with the lug at the end of the stem of the arm 24, and as this lug is carried around the under face of the cam it is depressed and the arm 24 is raised at its free end or moved away from the arm 23.

To hold the shaft 35 at the upper end of the diagonal slot 36, a cam 39 in the form of a quadrant is formed on-the outer or rear face 18 and works against the roller 40 on the pin 41, which projects from the inner face of the outer side of the frame of the attach ment, the cam being so positioned that its curved face rests upon this roller when the head is in vertical position and continues to rest upon the roller until the head has reached a horizontal position, when the cam passes beyond the rollerand the head,with its arms,may then drop. Connected to the outer end or head of the shaft 35 is a spring 42, connected also to the post 43 at a point above'the shaft, the strength of this spring being sufiicient to hold the head, with its shaft, normally in raised position and to permit the head to move downwardly only when the arms thereof bear the weight of a shock. When the shock is released, the spring referred to raises the head so that by operation of the rod 34 the head may be rotated to run the cam 39 onto the roller 41, it being understood that in the rotation of the head the cam holds the head againstdownwardmovement, due to the weight of the shock, until after the shock is moved to erect position.

As above described, the separate bundles are successively deposited upon the fingers l7'and the arm 23, the arm 24 being held at the upper limit of its movement, while the arm 23 is prevented from pivotal movement away from the arm 24. As the arm 24 is swung forwardly and downwardly and the arm 23 rearwardly and upwardly by rotary movement of the head'l8 the cam 33 passes from engagement with the lug of the stem 22, so that the arm 24 is released and its spring is permitted to draw it tightly against the bundles and hold them between it and the arm 23 in the form of a shock. This rotary movement of the head with the arm is continued until both arms and the head are in horizontal position, at which time the cam 39 has passed beyond its supportingroller, and the weight of the shock causes the arms and the head to move downwardly to deposit the shock with the bottoms of the bundles upon the ground. As the head 18 travels downwardly it travels also rearwardly by reason of the diagonal or slanting direction of the slot 36, so that the latch 26 is carried downwardly and rearwardly and strikes upon the pin 44 at the side of the frame of the attachment, so that as the head continues downwardly the latch 26' will be swung free from the lug or finger 25' to permit of the arm 23 swinging rearwardly or in a direction away from the arm 24. This rearward-swinging movement of the arm 23 acts to release the shock, and as the machine progresses the arm swings farther to the rear and is then drawn along the side of the shock, and when the machine has passed beyond the shock the spring connected with the stem 21 returns the arm to its originalposition. As soon asthe arms deposit the shock, so that the head is relieved of the weight of the shock, the spring 42 raises thehead, and therewith the arms, so that the latch 26 is raised out of engagement with its stop-pin, and the latch is permitted to return to its normal or active position. At this time the lug or finger 25 projects beneath the latch 26, so that the latch does not snap down into its active position until after the spring of the arm 23 has returned said arm to its normal or receiving position. After the head, with the arms, has been raised by the spring 42 the rod 34 returns the head to vertical position, with the ICC arms in position to receive the next lot of bundles, it being understood that when the head is thus rotated in its raised position the latch 26 is spaced such a distance from its stop-pin on the frame of the attachment that it swings clear of the stop-pin. This is because the axis of rotation of the head has been raised, in which position it is held during the return movement or downward inove-.

zontal position the strap is released and thefree ends of the fingers are permitted to drop.

.When the shaft 38 is rocked in the opposite direction to return the head to vertical position, the strap is drawn upon, so that the shaft 16 is rocked to raise the free ends of the fingers 17.

With this construction it will be seen that by properly timing the oscillation of the shaft 38 the arms may be held in proper position to receive a number of bundles and will then bemoved to erect the bundles, then to deposit them, then to release the bundles in the form of a shock, and finally to return to their original positions.

In practice modifications of the specific construction shown may be made and any suitable materials and proportions may be used for the various parts without departing from the spirit of the invention.
