FRANK G. GROVE, OF LURAY, VIRGINIA.

HARVESTER-BINDER.

SPECIFICATION forming part of Letters Patent No. 583,801, dated June 1, 1897.

Ap lication filed November 22, 1895. Serial No. 669,797. (No model.)

T0 at whom it may concern:

Be it known that I, FRANK G. GROVE, of Luray, in the county of Page and State of Virginia, have invented a new and useful Improvement in Harvester-Binders, of which the following is a specification.

This invention is an improved self-binder which is applicable to and maybe used upon any side-delivery harvester and in which the driving power may be derived from the rakeshaft or other moving part of the harvester.

The invention has for its object certain improvements; and it consists in the novel constructions and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the drawings, Figure 1 is a perspective view of my improved binder. Fig.2 is a top plan view thereof, parts being removed. Fig. 3 is a side elevation. Fig. 4 is a rear end view. Fig. 5 is a detail perspective view of the packer, and Fig. 6 is a detail perspective view of the binding mechanism.

The platform A may be that of any ordinary side-delivery harvester, and alongside such platform I support the table B, one end of which, preferably the front end, as shown, forms the binding-table and has an opening 0, in which the gavel is bound and from which the sheaf is discharged. In connecting the table B .with the platform A it is preferred to provide for a lateral adjustment of the table B, so it may be set with respect to the platform to adapt it for grain of different lengths. In securing this adjustment it is preferred to provide the table B with supporting-rods or bars D, which project beneath the platform A and fit in keepers d on the under side of such platform, as shown. To the platform is I journaled a rock-shaft E, having at opposite ends cranks 6, connected by links 6 wit-h the opposite ends of the table B, so such shaft E may be rocked to set the table B at different distances from the platform A. One of the cranks e is extended at E to form a handle-lever which is provided with a pawl engaging a rack-segment E thus serving to secure the rock-shaft in any suitable adjustment.

Over the table B, I extend guide-rods F, arranged at a suitable height to admit beneath them the gavel deposited by the harvesterrake. These rods F extend from the rear end of the table to a point in advance of the discharge-opening O and support the head 9 of the packer G, such head resting upon the rods F and having rods or similar portions 9 lapping under the rods F, so the head 9 will be held to and yet may slide freely along the guide-rods F. On this head g are supported the packer-teeth G, which depend from the head 9 and are rigid as the head moves forward toward the binding mechanism, but lift on the reverse movement of the packer to pass over the gavel that may have been delivered. Thus on its forward movement the packer will carry the gavel forward to the binding mechanism and yet will pass over the gavel that may be in its path as it is moved rearwardly to its starting-point. To reciprocate this packer, I provide a rock-shaft I, which, like the binder-shaft H, is preferably supported upon a slightly-elevated frame J immediately in advance of the dischargeopening 0. This rock-shaft I has a long crank-arm I, which is connected by a pitman I with the packer-head, and a crank 1 which is suitably connected with some moving part of the harvester, (it may be the rake-shaft, as shown, or of some other suitable part,) and I do not desire to be limited to any particular construction for operating this rock-shaft. In connecting the pitman I with the packerhead it is preferred to provide such pit-man with a shaft 1 which extends across the packer-head and is journaled in bearings 1 provided thereon. This construction is preferred because thereby I secure an even movement of the packer-head and avoid any twisting strains thereon and the binding of such head upon its guide-rods. Now, in operation, as the rock-shaft is operated the rakehead will be reciprocated toward and from the binding mechanism and the gavel will be accumulated, pressed into the dischargeopening, then bound and discharged, as will more fully appear hereinafter. In order that the gavel may be'properly compacted before it is delivered into thebinding-opening, I

provide presser-arms K, which extend from about the rear ends of the guide-rods F to a point just in rear of the discharge-opening O and are deflected just in rear of such opening down toward and bear upon the table B.

As the grain is forced forward by the packer the tension of these spring-arms K tends to resist its passage to the binding mechanism until it has accumulated in such quantities and with such a degree of compactness that it will, when forced into the binding-opening, properly operate the binding-arm and form a sheaf, as presently described. Immediately in rear of the binding-opening the table is provided with slots L, which communicate with the binding-opening C. The discharge arms L operate in the slots and are carried by a shaft L which has at one end a pinion L which is acted upon by racks carried by the binder-shaft, as presently described. The function of these discharge-arms is to force the bound sheaf out of the holder, consisting of the spring-arms M, in which it rests until it is bound, and so empty the binder for a new sheaf.

The tying apparatus may be of any suitable pattern and may include as a part thereof a pinion N, arranged for operation by a rack T on the needle-arm, as will be readily understood by those skilled in the art.

The binder-shaft ll supports the needlearm 0 and is provided with a crank-arm P and a crank-arm Q. The needle 0 has an extension O' below the shaft H, which extension is engaged by the gavel forced into the hinding-opening in order that the shaft H maybe rocked to cause the point of the needle-arm to descend in effecting the binding of the sheaf. To the crank-arm Q is connected a spring Q, which extends to and is secured to the framing. The function of this spring is twofold. 1n the first place it tends to return the shaft to both positions when it has been moved past its center, while in the second place by varying the tension of the spring the size of the sheaf may be regulated, it requiring a greater quantity of grain to rock the shaft 1-1 against the tension of such spring Q if the latter be strong than if it be Weaker, as will be readily understood. On the shaft Q are supported two rack-bars R and R, the former of which operatively engages the pinion L as the shaft H is rocked to binding position while the latter operatively engages such pinion as the shaft H is returned from binding position to its original starting position. These rack-bars R and R are pressed into contact with the pinion L by a spring R and such rack-bars are so constructed that they slip along the pinion in one direction of movement and bind or mesh such pinion in the opposite direction of movement, so that jointly they operate to cause such pinion and the shaft to which it is attached to move intermittently in the same direction. The crankarm P has for its function to cooperate in positively pressing the needle to binding position and in returning such needle from binding position. To this end I provide on the packer-head g a loop S, which preferably has a slight spring at its outer extremity S, so it may yield and pass up over and then spring down, embracing the point of the crankarm P.

In the operation of the invention as the gavel is forced into the binding-opening it will, by pressure against the lower extension of the needle-arm, tilt the shaft ll until the crank Q thereof passes rearwardly beyond its center, when the spring, acting upon such crank, will tend to further rock the shaft II and will bring the crank P to a position where it will be engaged by a point S of the loop S, which by its resilience will slide up over the point of the crank P until it drops down over such crank, when the rearward movement of the packer will push the shaft H and the bindenneedle positively back to a position where the crank Q passes in front of its center, and the spring Q will begin to act. In the operation of the loop S and crank-arm P if the parts be in the position shown in Fig. 3 and the loop S be moved up against the arm P it will ride up over the said arm and on the return movement will drag the arm P with it past its center, so the spring Q may act to force the binder-arm to binding position, the loop S then springing off the end of arm P. On the return movement of the loop S it will bear under arm Pand move the same toward its position (shown in Fig. 3) until its reaches the point where spring Q, may act to set the arm P to the position shown in Fig. It will be seen that the racks R and R will operate the pinion L to cause the discharging arm to first aid in compressing the sheaf and then by a continued movement to forcibly discharge the sheaf from its holder, such operations being repeated from time to time as the several gavels are successively accumulated, bound, and discharged.

On the downward movement of the needle the discharge arm should be turned far enough to compress the sheaf before it is tied, which may be regulated by the number of cogs or teeth on the rack-bar R, the rackbar R completingthe revolution of the discharge-arms as the needle goes back to its place.

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

1. The combination of the bindenshaft, a packer-head reciprocating toward and from said shaft, means for operating said head a projecting looped arm on the said head and an arm on the binder-shaft with which said looped arm engages substantially as shown and described.

2. The combination of the binder-shaft having the needle-arm, the reciprocating packer movable toward and from said needle, means for positively operating said packer and intermediate devices between said packer and needle whereby the movement of the packer in both directions correspondingly operates the binder-shaft substantially as shown and described.

The combination with the binder-shaft having a crank, and the reciprocating head,

5. The combination with the binder-shaft having a crank, of a spring acting upon such a'rm whereby to forcibly actuate such shaft in either direction when set past the center and devices whereby toset the shaft pastthe center in both directions substantially as set forth. I

6. The combination of the binder-shaft, a crank thereon, a spring acting upon such crank,'a reciprocating head, aspring-loop carried by said head and a crank on the bindershaft arranged for engagement by said springloop, substantially as set forth.

7. The combination of the binder-shaft, the sheaf-discharging shaft, having a pinion and racks carried by the binder-shaft and having reversely-disposed teeth engaging the said pinion substantially as set forth.

8. The combination with the binder-shaft having a lower extension for engagement by the gavel, a crank on said shaft and a spring engaging such crank'and adapted to operate the shaft in both directions, of a second crank on the binder-shaft, the packer and a springloop carried by said packer and adapted to detachably engage and to operate the said second crank in both directions, substantially as and for the purposes set forth.

9. In combination with the binder-table and the binding devices, the guide-rods located above said table, the packer sliding on the said rods toward and from the binding devices, and the spring-arms extending in the direction of said guide-rods and having portions bearing upon the table, the packer having devices projecting below the main portions of the said spring-arms substantially as and for the purposes set forth.

10. In a binder the combination with the binder-crank shaft and devices whereby the crank on said shaft when moved in either direct-ion past the center may be rocked a limited distance away from such center, of the reciprocating packer and connections whereby the said packer may operate to set the binder-crank past the center in both directions substantially as set forth.

11. The combination with the rotating discharging-shaft and the rocking binding-shaft of intermediate devices whereby as the bindershaft is rocked in one direction, the discharging-shaft will be turned to position to compress the gavel and as the binder-shaft is rocked in the opposite direction the motion of the discharging-shaft will be continued in the same direction as before to discharge the sheaf such discharging-shaft being thus given a complete revolution substantially as and for the purposes set forth.
