JOSEPH M. SHIVELY, OF ALFRED, KANSAS, ASSIGNOR T O DEERING HARVESTER COMPANY,

CORN-SHOGKER.

SPECIFICATION forming part of Letters Patent No. 681,517, dated. August 27, 1901.

Application filed February 6, 1901. Serial No. 46,321. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH M. SHIVELY, a citizen of the United States,residing at Alfred, in the county of Douglas and State of Kansas, have invented certain new and useful Improvements in Corn-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, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to devices for lifting the shock formed upon the machine and depositing it upon the ground. It is an improvement upon the machine patented to me May 5, 1896, No. 559,754; and it consists in means for rendering the shock-lifting core semi-automatic in its action in dropping the shock.

In the drawings, Figure l is a perspective view of the core around which the shock is formed, its radial arms and spreaders, and means for operating them, all as in position while sustaining the shock when forming there around. Fig. 2 shows the same parts, but with the spreaders and radial arms closed to the position they occupy when being drawn from the shock. Fig. 3 is a plan view of the tripping-latch. Fig. 4. is a side elevation of the parts shown in Fig. 3. Fig. 5 is a longitudinal sectional view of the devices for holding the radial projecting arms in position. Fig. 6 is a plan View of parts shown in Fig. 5. Fig. 7 is a side elevation of the means provided for locking the telescoping pipes together during withdrawal of the core from the shock. Fig. Sis a side elevation of parts shown in Fig. 7 with one of the bars it removed, but which has been turned through an angle of ninety degrees about a vertical axis; and Fig. 9 is a perspective view of a portion of the revolving table,showing the square stud which supports the shock-forming post in its vertical positionand causes the same to revolve.

to, at its center I secure to the rotary table the square stud b, which fits within the lower end of the square pipe A.

C is a square pipe outside the square pipe When the ropes are drawn, by means of Windlass or otherwise, the movement of the pipe A, having the disk Ct through the pipe 0, causes the disk at to press the spreaders outward. It is preferable that they be moved substantially equally, and hence I provide the chains a and link them together.

So far as now described this construction is found in the patent above referred to and need not be dwelt upon.

Upon the pipe C is clamped the sleeve F. It is constructed as shown in Figs. 5 and 6, its size being such as to pass freely onto the pipe C, but by means of the pinch-bolt f may be secured to the pipe at any desired place. This is for varying the vertical position of the arms to conform them to corn of dilferent heights.

f,- f f and f are arms pivoted to the sleeve F at f Each arm is provided'with an upturned end f near its pivot, as shown in Fig. 5.

Adapted to slide freely for a limited distance on the sleeve F is the collar G, having the downwardly-projecting peripheral flange 1 and H, and extending upwardly outside of a the pipe C are the bars h and h, and connecting the said bars at the top is the plate It.

Upon the two bars are the stops 7?? and h Surrounding the pipe 0 and the parts last described is the ring I, and extending upwardly from it is the bar I, having the notches i, 2', t

and i This bar is sustained at its upper end by mechanism soon to be described.

Extending from the case of the pulley d is a slotted link 61 In order that the core of my shocking-machine may rotate while the shock is accumulating without twisting the ropes 61 the swivel a, before mentioned, is provided, and in order that the core may rotate without carrying the bar I with itthe said core is free to turn in the ring I. Upon the top of the crane-arm -D is the latch for the bar I. This part is shown in detail in Figs. 3 and i. A slotted sleeve K is pivoted at and 70' between the arms 70 and 70 which arms are formed by bending the part as shown in Fig. 3. The part last mentioned is riveted to the upper end of the crane D. Within this slotted sleeve is pivoted the latch L, which is adapted to engage any of the notches z', 7}, 1' or t of the bar I. As the shock when suspended and being moved from the shocking-table is likely to swing from side to side, the sleeve K is pivoted, as before stated, and in order that the bar I may not crampwithin the slot in the sleeve the slot is made sufficiently long to permit of considerable vibration. The upper portion of the crane D is constructed of bars of iron D preferably formed,as shown in Fig. 1, to give place for securement of the end of the rope. This forms a support for the pulley d and place for attaching the locking device that engages the bar I. The spring-latch L, pivoted within the sleeve K, has secured to it the rope Z, which leads downward along the arm D to within convenient reach of the operator.

The operation of my device is as follows: With the arms f, f f and f raised, as shown in Fig. 1, and the shock formed, the rope d is pulled by Windlass or otherwise, and as the pipe A, to which the rope is indirectly connected, moves upward the disk a forces the spreaders E to the position shown. The core and shock surrounding it as a whole is then lifted to any desired height to draw the pipe A from the square stud b, which projects upward from the rotary shocking-table. The crane is then swung to such a position that the shock'may be dropped to the ground sufficiently far from the standing corn to permit the machine to pass upon another round, as in my patent above referred to. As the shock forming device is raised the bar 1 passes upwardly through the sleeve K, so that one of the notches "i, i, 71 or i is engaged by the latch L. When the shock is to be dropped, the rope d is set free. The Weight of the core and the shock surroundingit is then sustained by the bar I, the ring I of which comes in contact with the plate It and draws the collar G, through the intermediacy of the bars 71. and the loop H, upward relative to the sleeve F,

and thus disengages the arms f, f f and f and permits them to fall. Not only this, the weight of the entire apparatus being sustained by the bar I the pipe A is free to move downward by its weight or by the pressure of the spring e, and thus permit the spreaders E to collapse. The action of the parts thus far is to permit the shock to be dropped to the ground. The core has yet to be drawn upward through the top of the shock. This isdone by pulling upon the rope cl until the core is raised sufficiently high. It is plain, however, that if the pipe A were free to move upward relative to the other parts the disk a would force the Spreaders and prevent the withdrawing of the core from the shock. Upon the pipe 0 is the spring-latch M, with a pin m, adapted to enter the hole m in the pipe A. When the latter pipe is at its lowest position, with the two pipes locked together, it will be seen that the stress is reapplied to the rope C1 The spiders are not moved. The core having been fully removed from the shock is swung to its position over the shock forming table and lowered. The spring-latch L is disengaged from the notches t', z", '5 or 11 by pulling upon the rope Z. The pipe A is then placed in position on the square stud b of the rotary table and the latch M is withdrawn, so as to leave the pipes C and A free to move relatively to each other in the next operation of removing the shock. The arms f, f f and f are raised and the collar G permitted to engage them and hold them in the position shown.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a corn-shocking machine, the combi-- nation with a shock-forming post having pivoted arms, a trigger adapted to engage said arms and to lock them in radial posit-ion relative to said post and by longitudinal movement of same, relative to said post, to unlock said arms, and a shock-lifting hoist, of a trigger pull consisting of the notched bar 1' adapted to engage said trigger, a guide upon the arm of said hoist, said notched bar passing upward through said guide, and a catch upon said guide whereby the notched bar may -be arrested from downward movement when the hoisting device is permitted to lower the shock forming post, substantially as described.

2, In a corn-shocking machine, the'combination with a shock-forming post having pivoted arms, a trigger adapted to engage said arms and to lock them in radial position relative to said post and by longitudinal movement of same, relative to said post, to unlock said arms, and a shock-lifting hoist, of a trigger pull consisting of the notched bar I adapted to engage said trigger, a guide upon the arm of said hoist, said notched bar passing upward through said guide, and a catch upon said guide whereby the notched bar may be arrested from downward movement when the hoisting device is permitted to lower the shock-forming post, means for moving said catch out of engagement with said notched bar to permit the same to move downward when the shock-forming post is lowered to its position on the table, substantially as described.

3. In a corn-shocking machine, the combination with a shock-forming post having pivoted arms, a trigger adapted to engage said arms and to lock them in radial position relative to said post and by longitudinal movement of same, relative to said post, to unlock said arms, and a shock-lifting device conneoted to the top of said post by a swivel, of a catch on said shock-lifting device and a trigger-pull extending from said catch downward and surrounding said trigger, whereby the shock-forming post is free to rotate while forming the shock without afiecting the position of said trigger-pull relative to said lifting device, substantially as described.

4. In a corn-shocking machine, the combination with a shock-forming post having piv oted arms, a trigger adapted to engage said arms and to lock them in radial position relative to said post and by longitudinal movement of same, relative to said post, to unlock said arms, and a shock-lifting device, of a trigger-pull adapted to move a limited distance longitudinally relative to said trigger and to engage therewith, whereby the trigger is permitted to move downward with the shock-forming post for a little distance and the said trigger then arrested by engagement with the said trigger-pull, whereby the momentum of the descending post and shock is instrumental in setting the arms free, substantially as described. I

In testimony whereof I affix my signature in the presence of two witnesses.

JOSEPH M. SHIVELY.
