GRAIN-BINDER.

srncrrrcgrron forming To all whom it may concern Be it known that I, ERASMUS MILLER DEANE, a citizen of the United States, residing at St. Paul, county of Ramsey, State of Minnesota, have invented certain new and useful Improvements in Grain-Binders, of which the followingis hereby declared to be a full, clear, and exact description. g The invention relates to that class of automatic binders wherein the binding mechanism proper is tripped or brought into action through the medium of the accumulating gavel; and it consists of certain improvements in the construction of a machine for effecting this result, as hereinafter described, and distinctly defined in the claims following.

i In the accompanying drawings, Figure l is y a top plan view, Fig. 2 a side elevation, and

Fig. 3 a sectional view on line :0 m, Fig. l, of one form of machine embodying the improvementsf-only so much of the complete grainbinder being shown as is necessary to a clear understanding of the invention. Figs. 4,5, 6,-and 7 are minor detail views. Fig. 8 is a sectional view, similar to Fig. 3, of a modified form of machine; and Fig. 9, a detail view of a sliding box for the packer-shaft thereof.

For convenience, the invention will be fully shown and described as applied to the well- ];"nown Appleby grain-binder, set forth in Letters Patent No. 212,420, February 18, 1879,

and No. 260,63 l, July 4', 1882, respectively.

his to beunderstood, however, that the in vention is by no means restricted in usefulness to that particular type of machine, .but may beapplied to other forms as well, and whether these employ cord or wire insecuring the gavel.

I The binder-framc A issusta-ined at the side of'the main harvcster-frame by the tubes or rods 0 in manner well understood. .Across the binder-frame and beneath the binder-table extends the drive-shaft M, having near its outer end the sprocket-wheel b, which, through asprock et-chain engaging therewith, and with alike wheel on a driving-shaft of the harvester, communicates the power necessary to operate the several moving parts of the binder. The shaft M is sustained by the frame A within any of thelordinary journal boxes or bearings, and at itsinner end is secured, by suitable unipart of Letters Patent No, 291,497, dated January 8, 1884. Application filed March .24, 1883. (No model.)

versal couplingjoints, F F, to the inner end of packer-shaft M, which is sustained by the swinging shaft-supports c c, the projecting journals 0 of which are seated overhead in boxes (1 d, bolted to the binder frame. By

using the universal couplings or like connections between the main drive-shaft and packershaft M, the latter, being sustainedby swing ing supports 0 c, is free to move'bodily to and fro without binding or risk of disengagement or disarrangement of the shaft carrying the sprocketwheel b. Two cranks, N N, set opposite each other on the shaft Mf, carry the packers L L, the lower ends of which are joined to the links a, pivoted to the binderframe. The binder-arm K, mounted on shaft 0, swings up through the binder-table, between the packers L L, and free from interference with packer-shaft M.

At the back of the shaft-supports 0 care projecting lugs or ears c adapted to receive between them the reduced end of the base or seat 7a of a spindle, 7.7, which is pivoted thereto. The spindle 7- at its opposite end passes through a perforation in the stop-plate i, secured to the binder frame, and carries a threaded nut, by means of which the tension of spring 71, encompassing spindle 7r, and bearing at its ends against seat 7;. and stop-plate 'i, respectively, may be regulated. connection between spindles 7; 76 and supports 0 0 allows these latter, together with packershaft M, which they sustain, to swing backward about journals 0', and against the tension of springs 71 without undue stress or strain. Atrip-rod, Z, keyed at one end within a perforation of one of the journals 0 of swinging supports 0, so as to rotate therewith, is sus; tained near its opposite end in the side frame of the binder, and has secured to it a tripcrank, m, which bears against a secondary trip-lever, 0, (or an adjustable nut thereon,) mountedupon a stud or arbor, r, at the side of the binder-frame. The secondarytrip-lever 0 rests at its end beneath the primary triplever Q, journaled upon shaft 0 of the binderarm, said primary lever, as well understood, bearing against the long arm of a lever-stop,- P, pivoted to the side of a [drive-pinion, s, which is journaled loosely upon drive-shaft M. An arm, 0, fastened rigidly to shaft M,

The pivotal and having the projecting pins or catches t,

revolves constantly with said shaft, and imparts motion to pinion 8 whenever primary lever Qrises free and away from the long arm of lever-stop P, so that the short arm thereof may be forced upward by a suitable spring, 1;, into the path of the pins t, thus dogging or looking the pinion s to revolving shaft M. The pinion s communicates its movement through intermediate gear-wheels to the drivewheel E, which controls the operation of the binding mechanism, the binder-arm, and the ejectors; but as these several parts, their relation, and coaction form no part of this invention, and, besides, for the Appleby type of machine are well understood, and can be readily traced therein from the outline already given, a further detailed description thereof is not deemed requisite.

The crank-arm p, keyed to the shaft 0, of thebinder-arm,carries pivoted thereto a short rod encircled by spring y, the tension whereof may be "adjusted by suitable thumb-nut, so that the force necessary to lift primary triplever Q, against which lever the spring g bears, may be varied at will, and for a purpose presently to be described.

When loose grain is falling upon the bindertable from the elevator-apron, the continuous revolution of drive-shaft M causes the packers L on cranks N to rise alternately through slots in the table, advancing the loose grain, and compacting the same against the gavelsupporting finger S, (see Fig. 8,) or against any other suitable stop which may be arranged to arrest the passage of the grain preliminary to applying the band to the gavel. .As the loose grain accumulates it offers more and more resistance to the alternating action of the packers L, which resistance, being reflected upon shaft M, to which the packers are secured, causes said shaft to swing gradually backward about its pendent supports 0 and against the tension of springs h on the spindles k. The movement of swinging support 0 causes triprod 1, keyed to journal 0 of said support, to rotate slightly, thereby raising trip-crank m against the secondary trip-lever 0, which in turn lifts primary trip-lever Q away from the lever-stop P. Spring 12 thereupon forces the short arm of lever-stop l into the path of pins t, so that pinion s is locked with constantlyrevolving arm 0 of the shaft M, and the drivewheel E, through intermediate gear-wheels, is made, to describe one complete revolution to operate the binder and compressor arms, the binding mechanism, and the ejectors, as well understood. The binder-arm, in rising above the table to apply the band, advances the gavel and compresses the same somewhat, so that the packers, being relieved from the resistance of the gavel, are freeto return, together with packer-shaft M, to their normal position, the springs h acting against the swinging supports- 0 to accomplish this end. The reverse movement of supports 0 causes a correspond- 29min ing reverse rotation of rod 1, and through ita reversal or return to first position of the tripcrank m and secondary trip-lever 0. The primary trip-lever Q and lever-stop I? return to position when binder-arm passes below the table. The pinion sis thereby put out of clutch witharm 0, so that said pinion, and with it the drive-wheel E, is brought to rest, and remains thus, pending the accumulation of grain sufficient for another gavel.

It is obvious that the tension of springs h h may be adjusted by the set-nuts, so as to offer greater or less resistance to the backward movement of swinging supports 0 and shaft M, and that thereby and in like degree will the size and compactness of the gavel be determined, said springs acting in conjunction with the spring 1 to that end, and to control the action of the trip.

If desired, the springs h h may be omitted, in which event the tension of spring against primary trip-1ever Q will govern the movement of trip-rod Z, supports 0, and shaft M; or, on the other hand, the spring 3/ may be discarded and springs h h alone be employed, though in general it is preferred to use both in regulating the density of the gavel. Again, the main drive-shaft M may be connected to packer-shaft M by other means than the couplings F. These and all like modifications within the skill of the mechanic to accomplish involve no essential difference in invention, and can be readily effected, as convenience may suggest or the peculiarities of the machine may require, without in any wise departing from the spirit of the invention.

As thus far detailed, the operation of the improved automatic tripping mechanism is shown to be dependent directly upon the impact of the packers against the accumulated grain and the reaction or resistance arising therefrom, which is reflected upon the movable shaft of said packers. In the Appleby patents, heretofore referred to, the gavel rests against a certain supportingfinger, S, which, through the stress of the gavel thereon, finally rocks ash aft, 2,-an outer arm, 3, of which raises the trip-lever Q away from the lever-stop P. This trip mechanism of the Appleby binder may be retained entire and caused to co-operate with that which has been heretofore set forth, without further change whatever, in which case it is plain that both gavel-support S and packers L are sensitively set and coact, as against the pressure of the grain, to auto matically dog the pinion by which the binding mechanism proper is intermittently brought into play. To more certainly effect this cooperation of the several parts, to simplify con-- struction, and to enable the invention to be easily adapted to the Appleby machines now in use is the object of the style of machine illustrated by Figs. 8, 9, and 10. As shown therein the extension 2 of the gavel supporting finger S is formed with an eye to receive the reduced shank of an arm, R, connected to a rock-shaft, 2, said shaft being sus tained in suitablebearings of the binder-frame,

and having at its outer end an arm, 3, which having a threaded nut thereon, and pivotally joined at its opposite end to an ear of one of the sliding boxes 0, which sustain the shaft M of the packers L. The sliding boxes c are in this form employed in lieu of the swinging supports a, to allow for the to-and-fro play of packer-shaft M, as against the impact of the accumulated grain, although, as will presentlyappear, the swinging supports 0 may be used with equal success. The boxes of are retained in place on binder-frame A by headed bolts 0 passing through slots in the boxes, there being thimbles c on the bolt-shanks, to allow of more easy movement of the boxes. The spindles is, pivoted to boxes 0*, the stop-plates t, and springs h are the same in relation and operation as heretofore detailed. In this form of machine itis plain that as the grain accumulates against the gavel-supporting finger S, the packers 'L, and with them their shaft M, are gradually forced backward, the shaft moving with sliding boxes 0*, and these latter against the tensionof springs hi. Connectingrod 0" thereupon coacts with the pivoted fingers S to rock. the shaft 2 far enough to release the dog which controls the movement of the binding mechanism, as well understood. This direct cooperation of yielding gavelsupporting fingers with yielding packers to rock thesame shaft, has the merit of simplicity and sensitiveness, so that by adjustment of spring 3/ and of springs 72 (where these latter are uscd,) the tripping action can be effected without undue strain and the density of the gavel and the uniformity thereof more certainly insured.

Instead of rotating a rock-shaft, it is obvious that the yielding packers,as mounted,may be made to operate a trip-lever where such is employed, to control the binder-clutch, and that either the swinging supports a or sliding boxes 0* may be used to sustain the packer-shaft M, as convenience may suggest. Again,the yielding packer-shaft and its connections, as herein described, may be used exclusively to trip the binding mechanism, in which event the sensitively-set gavel-supports, or other like expedients to actuate the rocking shaft 2,will be entirely dispensed with.

Without limiting myself, therefore, to the precise details herein set forth, and again declaring that the improvements are not restricted to any onespecial form of grain-binder,

\Vhat I claim as new, and desire to secure by Letters Patent, is

1. In a grain-binder, the combination, with the adjustably-yielding packershaft, of the adj ustably-yielding trip-lever which controls the binder-clutch, said parts being so arranged that the movement of the packer-shaft shall be communicated to the trip-lever, substantially as described.
