1 IMPROVEMENT IN GRAIN-BINDERS.

specification fQmnn-g pm ff Letters attent No. 93,458, dated August 1o, 1869.

To all whom it may concern:

Be it known that I, WILLIAM LOTTRIDGE, of Charles City, in the county of Floyd 'and State of Iowa, have invented a new and Improved Grain-Binder 5 and I do hereby declare that the following is afull, clear, and exact description thereof, which will enable others skilled in the artto make and use the same, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to improvements vin grain-binding machines, the object of which is to provide a machine capableof binding theV sheaves with bands of straw, tov be made andplaced in position by the attendant.

I he arrangement of the machine is such th at the grain is delivered upon a raking device attached to the side thereof, which conveys the grain in gavels in a lateral direction up an incline and delivers it into a trough, across which a band has been previously placed bythe operator, with' the `ends to be tied around the sheaf in the notched or groovcd ends of a pair of ycurved compressing-jaws, which move up from each side and condense the sheaf between them, and present the said ends of the band to a twister, which twists the ends together, and

from which the twisted end ofthe band is taken and tucked between the band and the sheaf by a tucker, in a manner similar to that practiced when bound by hand.v After the tucking is accomplished a disch arger actuated by a spring strikes the sheaf at the end and drives it out of the trough, all as hereinafter more fully specified.

Figure 1 represents a transverse sectional elevation of my improved machine, and Fig. 2 represents a horizontal section of the same.

Similar letters of reference indicate corresponding parts.

A represents a laterally-projecting apron, whereon the grain is delivered from the reap in g-machine, or by any other means. An endless carrier or raking device, B, working over the said apron and up the incline C, over the roller D, gathers the grain into gavels, and carries it to and delivers it into the trough E, across which a band of straw, previously formed by the operator, who occupies the seat O, has been laid, with the ends in the curved grooves a of the vertical gripingjaws F F1. These jaws are arranged to embrace the grainand opposite end by a cord, L5,

condense it into a bundle, and also to present the ends of the band to the twister G. The

jaw Fis pivoted in slotted bearings at F2, and

jointed at F3 to a lever, F4, )ivoted at F 5, and

connected to th end F6 of a yoke, F1, deriving lareciprocating motion from the. crank F3 of the'driving7shaft. The said end F*3 of the'yoke works ina grooved support, F9. The jaw F1 is pivoted at F1o to fixed bearin gs, and jointed at F11 to the opposite end of the said yoke, also working in a groove. .By this arrangement the griping-jaws are opened and closed by one revolution of the crank-shaft. The said crankshaft derivesv motion from the shaft H of the driving-wheel H by suitable gear-wheels, so arranged that when the machine is moved backward they cannot rotate the`crank-shaft. These gripin g or conden sing jaws are provided with semicircular recesses or grooves I in their upper ends, which meet together around the shaft of the twister G, and hold the endsof the band while they are engaged by the curved arms of the twister, the shaft G of which is supported vertically -in the axis of the central opening formed'by the junction of theends of the jaws F F1, so as to suspend the twister immediately below the ends of the jaws. The

-said twister is kept in constant motion by a system of gear-wheels connecting with the crank-shaft. When the ends of the band have been sutliciently twisted together a crotched tucker, L, located in bearings upon the jaw F1, so as to be in theright position when the jaws are closed` to strike the twisted band immediately below the twister, is set into motion by a tappet, L1, on a shaft, L2, constantly moving and deriving motion from the crank-shaft, which tappet strikes the end of a lever, L3, supported on an axis, L4, and connected at its to a pulley, L6, onA

the shaft of the said tucker. The said shaft is provided with a retracting-spring, L1, to restore it to its normal position after having performed the tucking operation,which consists in detachin g the said twisted end of the band from the twister and the jaws, and tucking it between the band and the straw of the bundle, in the manner commonly practicedby hand.

After this operation has been performed the final Idischarging operation is e'ected in the following manner: A discharger, M, attached to a strap, M2, connected at one end to a discharging-spring, M3, and at the other end to a loose crank, M4, on the shaft of Va constantlyrevolving wheel, M5, is retracted by a fixed pin, M6, projectingfronl the face of the wheel M5, which forces the said loose crank in the backward direction until it rises above the axis of the hub, when 'thedischarging-spring will cause the strap to ily forward, carrying the discharger M against the end ofthe bundle, ejecting it from `the mouth of the receiver, a slot being formed in the bottom thereof to allow the discharger to move a sulcient distance for the purpose.

I do not desire to limit myself to the arrangementot the machinery which I have herein shown for actuating the essential elements of l my invention, which I consider to be the receiver, gri pin gjaws, twister, and .tucker, when combined and adapted for tying the bands of straws, as `other arrangements may be employed with good results for operating these principal elements.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- Y 1. The arrangement of the receiver E, griping or condensing jaws .F F1, twister G, and tucker L, as .herein described,'rfor .thepurpose specified.

V2. The discharger M, constructed as described, in combination with the spring M3,

loose crank M, pin M6 on thewheel M5, and

the slotted receiver E, substantially as described, for the purpose specilied.

3. The arrangement of the griping-jaws F F1 with relation to each other, and the lever F4, yoke F7, crank F8, grooved supports, and slotted and fixed bearings, substantially as herein shown and described, for the purpose specified. 4. The arrangement of thetwister G G with :reference to the .griping-jaws F Fl and tucker L, whereby itis adapted to operate inthe manner described, for thepurposeset forth.y
