CORD-CARRYING IVIECHANISIVI FOR CORN-SHOCK COMPRESSORS.

SPECIFICATION forming part of Letters Patent No. 767,457, dated August 16, 1904.

Application filed March 28, 1904.

To fbi/Z ufl/,mit 7115 may concern:

Be it known that LJOHN I/V. IVnBsTEma citi- Zen of the United States, residing at Chicago, in the county of Cook and State of Illinois,

- have invented a new and useful Improvement in Cord-Carrying' Mechanism for Corn-Shock Compressors, of which the following is a complete specification.

This invention relates to devices to be used in connection with corn-harvesting machines in which the shock is formed upon a rotating table and about a shock-forming standard. The purpose of the invention isto provide means for passing' both the cinch-rope and tierope about'the shock with ease and despatch after the shock has been formed. One of the methods in common use for accomplishing this heretofore has been to thrust the pin carrying the cords into the shock at the beginning of the last revolution. This occasioned more or less trouble, because of the fact that it was necessary to go a suicient distance to eifect just one revolution of the table after the formation of the shock, which required somewhat close attention.

For a complete description of the machine in connection with which this improvement is shown reference is made to the patent granted to J. M. Shively, April 7, 1903, No. 724,515.

Referring' to the drawings, Figure l represents a rear elevation of a complete machine embodying my improvement with many of the non-essential parts being shown in dotted lines. Fig. 2 is a plan view of the principal parts of the machine, illustrating the relative position of the cordcarrying device and shock, the said cord-carrying device being' shown in the position-which it occupies after having been let fall on the forward side of the shock, the shock being' represented in section adjacent to the band which is shown in dotted lines; and Fig. 3 is an enlarged detail view in section showing' the construction of the cord-engaging device of the shock-compressor. l

In the drawings, 1 designates the main frame of a corn-harvesting machine; 2, the main supporting' and driving' wheel; 3, the

serial No. 200,256. (No'modei.)

grain side wheel, and L the wall surrounding 5o the rotating shock-forming table.

5 represents the crane (shown in Fig. l in dotted lines) for removing the shock from the machine, and 6 is the twine-box.

7 designates one ,of the inclined braces for 5 5 supporting the crane, and 8 a vertically-arranged standard arranged adjacent to the shock-forming table on the stubbleward and forward side thereof. In the upper end of this standard 8 and in a suitable bearing on 6o the said brace 7 is mounted the bar or rod 9, having a horizontally-eXtending portion 9', provided with the transversely extending arm l0. The horiZontally-extending portion 9/ of this rod is disposed slightly oblique with 65 respect to the line of advance, the rear end being farther stubbleward, as shown. The object of such arrangement is to cause the free or upper end of the arm which carries the shock-compressor to move in a path lead- 7o ing rearwardly as it descends, and it follows that the farther stubbleward the rear support of the horizontal portion 9 of the lbent bar 9 is located the farther rearward the free end of said arm l() moves, the limit of such effect being reached, of course, when the horizontal portion assumes a transverse position, which would then cause the arm to swing directly rearward. It is designed to have the deflection sufficient so that the free end of the arm 8o will swing in a plane substantially vertical and intersecting the shock-forming table at a position near its edge and lodge upon the liaring side of the shock. To hold the arm 10, with the shock-compressor mounted thereon, 8 5 in its inoperative position, the upper end of the standard 8 is provided with a bent end 1l, which projects into the path of said arml and against which it normally rests.

The corn-shock compressor and carrying 9o device may be of any construction, but pref* `erably of that construction shown in Fig. 3.

In this figure is shown the device covered in an application filed December 3 1903, Serial No. 183,562. This deviceconsists, essentially, of the open casting 12, in which is pivotally mounted the sheave 13, and in operative relation with respect to this sheave is the bellcrank pinch-lever 14, one end of which engages the rope by pinchingthat portion thereof lying between it and the said sheave 13, while to the other arm of said bell-crank pinch-lever is secured the tiXed end of the cinch-rope 15, while the free end of said rope passes around said sheave 13, as shown. The lower end of this casting 12 is provided with a socket 16, which releasably engages the upturned end 10 of the said bent rod 9.

17 is a spring-clip, beneath which is temporarily secured the tie-rope Q0 when being passed about the shock.

On the rearward end of the bent rod 9 is the crank portion 18, formed, preferably, integral with the said rod and by which said rod is caused to rock.

The operation of the device is as follows: After a complete shock has been formed the tie-rope 2O is secured beneath the spring-clip 17 of the shock-compressor, while one end of the cinch-rope 15 is permanently secured thereto. The crank 18 is moved, which causes the upper end of the arm 10, carrying the said shock-compressor, to fall against the shoclrin such a way that it will lodge on the forward side of same, where it occupies the position shown in dotted lines in Fig. 1 and in full lines in Fig. 2. 'Ihe operator standing in the rear of the shock grasps the cord-engaging device and raises it to the proper height. He then takes the free end of the cinch-rope 15 from the guide 19 and engages it, as shownin Fig. 3, and draws it tight, at which time it will be in the position shown in dotted lines in Fig. 1. The free end of the tie-rope will be at hand beneath the clip 17, while the run or loop from the box will beheld by the guide 19. This loop or run the operator takes, draws tightly around the shock, and ties the same, after which the string is severed, the cinch-rope disengaged, and the shock removed. The rod 9 is then turned to its normal position, as shown in full lines in Fig. 1, and the cord-engaging device again placed thereon ready for use upon the succeeding shock.
