CORN-HARVESTER.

SPECIFICATION forming part of 'Letters atent No. 612,537, dated October' 18, 1898.

Application filed December 18, 1897. Serial No.` 662,498. (No model.)

To @ZZ whom it may concern:

Be it known that I, FRANK LAURENCE WE1! after being bound it is discharged `onto the ground in a standing position.

This invention primarily has for its object to provide a machine of this character of `a very simple and inexpensive nature in which the several parts are easily manipulated and arranged to facilitate the formation of the shock and then deposit such shock in the field at any desired point in a standing position.

This invention also seeks to provide a ma- Y chine of this character having suitably-arranged devices which will serve to steady the top of the shock as it is accumulated and which can be instantly swung out of engagement with the shock as it is discharged to a standing position, whereby to free the upper end of4 the shock of contact with anyfixed member which might serve to retard the free discharge thereof. i

Another object of this invention is to provide a machine of this character having a; novel form of dumping-platform which when lifted from its support closes up automatically and provides for openings through which the shock can drop in a standing posi# tion onto the ground.

The invention also has other minor objects in view, which will hereinafter be specifically referred to; and such invention consists in the peculiar combination andnovel arrangement of parts, such as will be first described in detail and then be specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which- Figure l is a perspective view of my improved harvester. `Figxf is a longitudinal section thereof, the head-supporting yoke-frame being shown swung to its elevated position in dotted lines. Fig. 3 is a transverse secon the arm 9.

tion, the folding platform being shown to its normal or expanded position in full lines `and in its folded or elevated position in dotted lines.

.Referring to the accompanying drawings, in which like numerals indicate like parts in all the figures,'l indicates a platform of suitable length and width, which is supported, preferably near the rear end, on the axle 2, having supporting-wheels 3,' the front end of such platform being supported on the wheels 4, which in practice may be held for vertical adjustment in its bearin-gsAs, suchbearings La carrying the clevis or draft member '5,' as

clearly shown in Fig. l of the drawings.

The front end of the platform, which is of a substantially triangular form, is equipped with the conventional long cutter-blades 6, and adjacent the cutter end the platform is provided with two operators seats 7, arranged one on each side of the center.

8 8 indicate a pair of standards which extend up centrally from the platform 1, which support a horse or supporting-arm 9, which extends rearward the full length of the machine and forms the main support for the upper end of the shock as it is being formed. l

1 The standard 8 extends above the arm'9 and forms the support for the swinging head or yoke-frame, which consists of a bar l0, eX- tended longitudinally rearward over the arm 9, pivoted at `10a to the standard 8 and provided at the rear end with a short pendent bar 10b, to which the yoke 11 is secured, it also having apendent rest member 10c, adapted when the frame 10 is swung down to seat lThe front end of the bar l0 is extended forward of its pivot and forms a handle which projects in convenient reach of either operator, whereby the yoke-frame can be swungup to the position shown in dotted `lines in Fig. 2, for a purpose presently eX- plained.

The yokellinpractice is formed of a stout spring wire or band, centrally secured to the member l0b and having its ends extended horizontally forward, closing toward each other, and then curvedoutward, so ast-oprovide a convenient guide-mouth and a pocket to receive the heads of the several stalks IOO which form the shock. By forming the yoke of spring metal it is manifest the sides of the pocket will expand to1 admit of a large quantity of heads when the shock is to be formed of more than the average number of stalks. The rest-bar b also forms a central division member for dividing the upper or head end of the shock, which is also divided and supported by the longitudinal bars 10 and 9.

By referring now more particularly to Fig. 2 it will be noticed the arm 9 and the yokev fra-me extend beyond the rear end of the platform 1 over the supplemental platform 12, the construct-ion of which forms the essential feature of this invention. This platform 12 is formed of two longitudinal members 12 12, pivotally joined to fold transversely of the machine and normally held by any suitable means-such as, for example, springs 13, as shownto their extended position, as shown in full lines in Fig. 3. The springs 13 permit the pivoted section to fold together instantly under the weight of the shock and deposit the latter squarely upon the ground. Then extended, the platform 12 is of substantially the width of the front platform 1, and when adjusted to form the support forthe base of the shock the outer ends of members 12 12 are supported on roller-bearings 14 14, journaled on the inner face of the side extensions 1 of the front platform-frame, said extensions 1 having vertical flanges or guides 1b to hold the butts of the stalks from slidingoff the platform 12 sidewise. The object in providing roller-bearings for supporting the platform is to facilitate the movement inward of the members l2 when the platform is elevated in the manner presently described.

The platform 12 is supported centrally atj the front and rear ends on guy chains or ropes side of such arms.

15 15, one of which, 15, passes up over a pulley 16, hung pendent from the rear end of the; arm 9, and a pulley 16 on the front end of such arm 9, from which it passes to a windlass 17, journaled between the uprights 8 and` 8 on suitable horizontal cross-bars. The rope 15 passes up over a pulley 16 and then over the windlass 17.

The operation of my improved harvester isl best explained as follows: When the parts are arranged as shown in Fig. 1, the machine" is drawn forward between two rows of stalks, the operators (one at each side) gathering the stalks of their respective row as they are sev-` ered by the cutter-blades and placing them` in position on the platform 12 with their heads in the yoke-pocket, the operator at one side resting his gathered stalks against one side of the arms 9 and 10, while the other operator deposits his stalks against the othery When the shock is half built, on either side top fingers 25, pivoted to the bar 10 to swing transversely on the machine, as clearly shown in Fig. 2, are turned down at the will of the operator to hold the shock from falling forward, such fingers being also turned down when the machine is going downgrade to hold the saidl shock from falling forward. After a suitable amount of stalks have been gathered to complete the shock the heads are bound in the usual manner by means of the clamp-rope 26, which draws the head of the shock tightly around the center projecting member 10 and holds the head in position to be secured bythe tying cord or wire 18, which in practice is held in a suitable box mounted on the arm 9, and to hold the shock from sliding off the back end of the machine as the same is drawn upgrade pivotal back fenders 27 are provided, (see Fig. 2,) which are adapted to be conveniently operated by means of crank members 27 at the front end of the machine. The machine is then drawn to the point where it is desired to stand the shock, after which one of the operators turns the crank of the windlass 17 and draws up the guy-ropes, which being secured to the center of platform 12 elevates the platform,the side members of which, however, owing to the weight of the shock thereon, fold inward from under the shock, (see dotted lines, Fig. 3,) which then sinks to the ground and stands erect. The operator then elevates the yoke-frame and the yoke from the head of the shock, so as to free it from engagement with any fixed part except the longitudinal support 9 as the machine is drawn forward. The team is then started and the machine drawn away from the shock, it being manifest that as the platform 12 is practically closed up it will freely pull from under the shock without danger of pulling it over, as the upper or head end is suitably guided and supported by the bar 9. After the machine is pulled away from the shock and the platform-sections 12 relieved of weight such sections (through the medium of the expansionsprings) will again assume their extended positions, it being obvious that by unwinding the windlass the platform 12 can be quickly turned to rest on the roller-bearin gs on frame sides 1.

While I prefer to use my dumping-platform and shock-head forming and guide means with a cutting mechanism as shown, it is manifest that such devices may be used in connection with any other shock-cutting means.

When the long triangularly disposed knives such as shown are used, I prefer to also provide supplemental rotary cutters 20, secured on the long cutters or the platform in such a position that they will also form guides to bring the stalks in proper position for a quick cutting action.

'While I prefer to arrange the several parts constituting my complete invention substantially in the manner shown and described, it is manifest the detailed arrangement of parts may be varied or modified without departing from the scope of the appended claims.

Having thus described my invention, what lOO IIO

I claim, and desire to secure by Letters Patent,is i A 1.
