IMPROVEMENT IN GRAIN-BINDERS.

Specifica-tionforming part of Letters Patent No. 42,322, dated April 12, 1.864; reissue No. 2,336, dated August 14, 1866.

To all whom 'it may concern Be it known that I, SAMUEL J. WALLACE, of Carthage7 in the county of Hancock and State ot' Illinois, have invented a new and Improved Grain-Binder ,z and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying' drawings, and to the letters ot' reference marked thereon, in which- Figure l is a front elevation of my improved grain-binder attached to the dratt or wheel traine of a reaping-machine, showing the several parts in their relative positions for receiv ing the sheaf ot' grain to be bound. Fig. 2 is a rear elevation, showin g the same parts in their relative positions in the act of compressing and securing the band around the sheaf. 3, Sheet 2, isa perspective view of the reel detached from the binding apparatus, showing the curved arm and tooth for securing the reel to its axis for taking up the slack strand. Fig. 4, Sheet 2, shows in detail the slotted plates, band-cutter, and spring holding-fingers ofthe curved swinging arms. Fig. 5, Sheet 2, is an enlarged perspective view ot' the slotted twister detached from the binder.

Similar letters of reference indicate corresponding parts in the several tigures.

This invention has for its object the compressing and binding of grain into sheaves as fast as it is cut by the reaping-machine. The binding apparatus is designed to be attached to the draft-frame of the reaper, and in such relation to t-he drivers seat that the driver can control the binding apparatus with very little extra labor, and by the simple operation of a lever.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

A is the usual draft-frame of a reaping-machine, supported on the wheels B B', and C is the drivers seat, which is supported on the frame A in the usual position for the drivers seat of a reaping-machine. D is a curved binding-arm, pivoted at a to a bifurcatinglever,D1, and again at a1 to a longvibrating upright arm, D2, which latter is pivoted at a2 to one side of the-frame A. The bifurcated lever D1 is pivoted at its lower end to the side of the drivers scat, and one arm ot' this lever extends up and forms a handle, which is in convenient position for the driver, who can perform the operation of binding the grain by giving a vibrating movement to this hand-lever.

Below the curved swinging` arm D, and in,

or nearly in, a vertical plane therewith, is arranged a curved bed, E, which is secured and properly braced at one end to the frame A ot' the reaper. This curved bed E is intended to receive the loose grain from the platform of the reaper and retain the sheat until the binding operation is etl'ected; and to this end this bed E has a curved tongue, El, projecting from its outer end, over which the loose grain passes as it is being raked into the binding apparatus.

On the swinging end ot' the binding-arm D the wire-hand holder is secured, which consists of two curved slotted plates, b b, secured -together at their extreme ends, as shown in Fig. 4 ot' the drawings, and having a pertoration,b, formed at the upper termini ofthe slots b2 b2, for receiving the outer or counter twist of the wire band, as will be hereinafter described.

Along one side of the swinging end of the curved bar D is a curved toothed rack, c, the length of which is equal to the length of the slots in plates b I), and at or near the terminus ot' the upper end of this rack c is a knife, d, which inclines from this racl; downward, as shown in Fig. 4 of the drawings. At the extreme outer end ofthe swinging arm D, and on each side ot' this arm, are two spring-fingers, e e, which are secured to a spring, e', the lower end of which is bent at right angles'under the end of arm I), and projects forward a suitable distance to be acted upon by the curved edge ot' a plate, E2, which is secured to the lower side ot' bed E, and thrusts this spring outward, thereby pushing back the spring-ingers e e, immediately after these iingers have put the end oi' the wire which is carried by the arm I) into the radial slot in the twister F.

The twister F, which twists the two ends of the wire band together atter the bundle ot' grain has been suiiciently compressed, consists of a toothed wheel,F, having its axial bearings in the bed-plate E and the curved thrusting-plate E?, as shown in Figs. l and 5 ot' the drawings. This wheel F has a radial slot,f, cut into it, extending from its axis toits circumference, said slot being of sutticient size to receive two wires to be twisted together, as will be further described hereinafter. This twister F is arranged on the outer end of the bed E, in such a relation to the curved rack c on the binding-arm D that the teeth of this rack will engage with those of the twister F and rotate the twister, for the purpose ofgiving the tie-twist to the wire band, while the baud is drawn tightly around the bundle oi' grain.

G is a curved plate, which is secured at its forward end to the extreme outer end of the curved bed E, and which vextends from this point downward and backward, so as to have a sufficient space between-the bottoni ol' plate E and this plate G to allow the curved plates b b to pass down and present the band-wire to the twister F, to be twisted together.

The bandecarrying reel Il consists of two circular disks,`g g', which are connected to a hub in the usual manner of constructing a reel or spool. This reel is allowed to turn freely on its axis al when the arm D rises; but when the arm D commences its downward motion this reel is fixedV to its axis and made to turn backward, as will be further described.

Between the disks g g the wire which is used for binding the grain is wound, and carried thence to the friction-roller t', down through the curved bed E; thence under this bed to the outside ot'and through a. hole, `1/,iu the plateG; and, iinally, the end ot' this wire isheld lirinly between the slots b2 b2 in curved plates b Z, as shown in Fig. 1 ofthe drawings.

The reel-disk g has a toothed wheel, 7.", secured to its outside surface, concentricallv with its axis, and between this disk g and the pivoted end ofthe swinging arm D is fixed to the pivot al a bent arm, J, which is'actuated by the hand-lever D,l so as to cause a pin,j, on lever J to engage with the teeth of wheel k, and hx it to the axis al, thus rotating the reel backward,and drawingthe band ti gh tl y around the sheaf preparatory to cutting the wires and severing the bundle from the machine. The operation of the curved arm J, with its pin j, upon the toothed or ratchet wheel 7c is like that of a common pawl and ratchet, with this addition: the curved arm J, by its lower or curved end pressing against the side of the long arm D2 when this arm is moved outward, engages the tooth or pin j with the ratchetwheel k, and when the long arm D'l is moved backward or toward the driver, the pawl-arin J disengages the toothj from the ratchet-wheel it', and allows the wire to unwind from the reel.

Besides tighteningthe band around the sheaf, by giving the reel a backward rotation, as just described, it is further tightened, in consequence of the reel being raised by the long arm D2, as this arm describes its arc from the pivot a2, and the curved arm advances to the twister F.

The operation of my invention is as follows: The band-wire, (wire being used instead of twine,) which is represented in the drawings,r is wound upon the reel, and carried from thence under the bed E toward the outer end of this bed, and passed through plate G at a point which is coincident with the axis ofthe twister grain. The grain is now raked from the platform ot' the reaper (in any ot" the usual modes of raking gra-in from the platt'orin ot' reapers,)against the slack wire, carrying with :it the slack wire into the curved bed E, and at the same operation drawing the wire through slotfinto the axis of twister F. Then a suflicient quantity ot' grain is thus raked into the binder over the slack bindingwire, the driver forces thc'hand-lever D1 outward, thus depress ing the outer end ot' arm l), and carrying the free end ot' the wire over the confined bundle ot' grain.

The end ofthe wire which is held by the arrn D is now forced into the axis of the twister F,

.and held down in its place on both sides of this twister by the spring-fu'igers e e. The teeth of rack cnow engage with the twister, rotate it, and canse it to twist the wire tightly around the bundle of confined grain. During this operation the arm D continues to descend, and the reel is caused to rotate backward, so as to take up the slack wire, and thus draw the band tightly, in the `nar. ver described, around the shea?. linrnedateiy the fingers e e put the end ot' the wire into the slotfin twister F, and the twister begins to rotate, these hngers are thrust outward, in consequence of the arm e coming in contact with thn curved edge of plate E2, and thus allow the i isted wires between the plates G and to pass between the slots in plates b b.

The curved arm D still further descends, twisting the wire and compressing the sheaf, until the knife d severs the twisted ends ot' the wire from the upper side ot the twister, and thus releases the bound sheat' froml the machine.

The arm D, after this operation, begins to ascend, and in this return stroke the twisted end' of the wire, which is left in the slot fof the twister, is pulled out of the twister by the slotted plates b b, and the twisted knot, which is left on the end of the wire, slips through the first slot b2 at the point b1, and is caught between the two plates l) b, where it is held in a position to be presented to the slot j' in the twister in the next downward stroke of the arm D.

It will be seen that the slotted plates b b and their spring-fingers e e hold the free end of the wire firmly, and draw out suiicient slack from the reel to commence the operation of binding. They then unite the ends of the wire in the slot in the twister, and finally grasp the end of the wire again, when it has been cut o, to repeat the operation.

The return stroke of the curved arm D is effected by the driver, who draws the handle'ver Dl toward him, as soon as he finds that the ignite d has severed the wires which connect the sheaf with the curved bed of the binder.

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