CORN-HARVESTER.

SPECIFICATION forming part of Letters Patent No. 509,162, dated November 21, 1893.

Application filed September 16, 1892. Serial No. 446,111. (No model.)

peculiar construction and arrangement of the various parts of a corn harvester, with two knives forward of the rear axle, a slatted platform and the mechanical means for holding the shock while it is being bound.

That the invention may be seen and fully understood by others, reference will be had to the following specification and annexed drawings forming a part thereof;

Figure 1. is a 'side view showing the slatted platform raised,one wheel and one side being broken away to show the mechanical workings to better advantage. Fig. 2. is a similar view showing the platform dropped. Fig. 3. is a front end view. Fig. 4: is a plan View. Fig. 5 is a partial plan view showing a diiferent means for depositing the shocks. Fig. 6. is a partial side view of same. Figs. 7, 8 and 9 are enlarged views of the compressor detached, hereinafter fully explained.

Like letters of reference designate like parts 11 the drawings and specification.

In the drawings the knives are denoted by the letters a. a Figs. 3 and 4. These knives are set at an angle of forty degrees more or less, with the bevel up. The operators stand on the platform I), back of the knives. To the platform b is attached the falling leaf deck 0, having the slats d hinged thereto as shown. A lever e for operating the deck and hinged slats is arranged conveniently for the operator, the operation of WhlOh 1S hereinafter explained.

f. are twoguides or holders; for holding the shock of corn while being bound. These holders f. f are connected and operate conjointly with the falling leaf 0 and slats d by means of the cranks g. g and arms h. h.

The mechanism for operating the falling leaf and slats is as follows: The lever e is held in an upright position by a spring catch or trip 2' as shown in Fig. 1. When 1n this position the leaf and slats are raised. The bar j is in a horizontal position over the slats. The rods lo and Z have one terminal pivoted to the bar j and their other terminal to a fixed block m on the floor of the harvester. The rod n also has one terminal pivoted to the bar j and the opposite terminalto the lever e. The falling leaf 0 is connected with the lever e by means of the pivotal rod 0, chain 0' and the rigid rod p on the leaf 0. A rod q is also pivoted to the lever e, and extends back to the slats (1, said rod q having a cross piece q thereon resting on the slats. It will readily be seen that when the lever e is released by the trip 7; and thrown back, the leafi c, slatsd and bar j will be forced down to the position shown in Fig. 2. through the medium of the lever and connections above described, and the cross piece q will sweep back on the slats d. for the same reason. The guards or holders f. f. will be thrown up through their connection with the leaf 0 by means of the cranks g. g. and rods 71.. h.

The compressor (of which Fig. 7. is an enlarged detached view of one side showing the lever in a perpendicular position, Fig. 8. a

view of the opposite side, with the lever partially thrown down and Fig. 9. a detached plan view), is situated in the middle of the floor of the harvester, convenient for the operator. Said compressor is constructed and operates as follows: The standard 0" is rigidly attached to the floor, and has the cross piece r fixed to its upper terminal. The lever sis pivoted to one terminal of the cross piece 4*. The lever s has two rods 8' and s pivoted thereto. The rod 8' is also pivoted to the sleeve 15 on the standard 7'. The rod 8 which is pivoted to the lever s by means of the arm 3 is also pivoted to a sliding bar 11., arranged to slide horizontally against the cross piece r. The sliding bar a, is extended on each side forming the curved arms u and a at the op posite terminal thereof from the lever s. A ring '0 Figs. 1 and 2. with two cords v. 11 attached thereto is arranged to slide freely on the rod w, on top of the bar j. J

The operation of the compressor and the entire machine is as follows: The corn after being cut by the knives a. a. as the apparatus is drawn forward, is caught by the operators, carried back and placed against the bar j on both sides, beyond the links is and Z and the arms u. and n of the compressor. When a sufficient amount to form a shock of the de- 5 sired size has been so placed, the cords v and o are placed around the shock, crossed and one passed on one side of the pulley Figs. 1, 2, 7, 8 and 9, the other one passing on the other side of said pulley. [0 then together passed over the pulley y and the terminals made fastto the sleeve tin any manner whereby they may be readily detached, the form herein shown being simply a notch in the sleeve t which catches knots I on the ends of the cords. The levers is then forced down to the position shown by dotted lines in Fig; 7 or simply as shown in Fig. 8.

This will cause the loop formed around the shock to contract and the sliding barn to be 2o forced forward, thus holding the shock firm until bound with an extra cord. The cords o ando are then released from their terminal fastenings on the sleeve t. The-lever e is then released fromthe' trip '5. and carried back as shown in-Fig. 2, which drops the slats and forces the shock off, in a standing position.

In place-of the sweep q an endless apron A. may be used as shown in Figs. 5 and 6, which" may be operated by any known suit- 0 able means as a band and gear wheels as shown.

What I'clai'm, and desire to secure by Letters Patent, is-

The twocords are.

a sliding bar u and sleeve 15 operated conjointly with the pivotal rods 8' and s and the cords o and 0 whereby a temporary binder is formed for theshock', holding it in place until firmly bound, substantially as and in the manner set forth.

In a corn harvester, the=combination of 1 the binding lever mechanism with the=fa1ling leaf 0, slatted platform d,stationany platform b lever e and connections. as described and knives a. a. operating conjointly with the arms h. h. cranks g. g and holders fifisubstantially in the: manner asand forthe purpose setforth.

In'testimony whereof I afli'x'my signaturein 6o presence'of two witnesses.
