SPECIFICATION forming part of Letters Patent No. 273,325, datei March e, less,

Application led April 25, 188'2. (Model.)l

llov all whom it may concern Be it known that I, WILLIAM VAN HORN, a citizen of the United States ofAinerica. residing at Piqua, in the county of Miamiand State of Ohio, have invented certain new and useful Improvements in Grain-Binders, of which the following is a specification, reference being had therein to the accom panying drawings.

rIhis invention relates-t0 that class of grainbinders in which the grain is bound with cord and it consists in certain peculiarities and improvements therein, as will be hereinafter described and claimed.

In the drawings, Figure 1 represents a perspective view taken from the front, and Fig. 2 a perspective taken from the rear, ot' a grainbinder constructed according to my improve'- ments. Fig. 3 is a detail View, in elevation, of the rear ot' the machine, wheel K being removed. Fig. 4 is a top plan view, and Fig. 5 Fig. 6 represents in sectional elevation the needle with my improvements applied thereto. Fig. 7 represents a perspective View ot' the sheaf or gavel compressor. Fig.8 is an elevation of a part ofthe gearing. Fig. 9 is afrontl elevation of my improved grain-packer. Fig. 10 represents in perspective one ot' my packera-rms. Fig. 11 represents in perspective a cam and rack wheel for operating the cord holding and tying mechanism. Fig. 12 represents in elevation the cord-tyer in position in the framing. Figs. 13 and 14 represent the cord-tyer and sleeve separately. Fig. 15 shows in rear elevation, and Fig. 16 in plan view, a portion of thc gearing with clutch mechanism. Fig. 17 represents in perspective vthe cord guiding and throwing arms and knife-operan ing arm's. `Fig. 18 represents in perspective the gavel holding or supporting andthe gavel- `discharging arms. Fig. 19 shows the cord,-

holding device separately. Y A represents the patform or apron upon which the grain is recl ived trom the elevator.

This platform may bc secured in any suitable' manner to the elevatorfraine, and is slotted, as shown, to admitof the passage therethrough of the needle and its attachmentsand the gavel-compressor, and also the gavel holding and discharging arms.

Journaled in bearings c on the under side of the platform A is the rock-shaft B. These A,bearings are secured to the platform by ears I, and extend farenough in a downwarddirection at their center to allow of the gavel holding and discharging arms revolving within the slots in the platform without comin-g in contact with shaft B.

C represents the'cordspool, which is journaled in bearings c, secured to the underside of the platform. Frein this spool the. cord passes to and through the stapleV d, and from thence to staples ein the compressor-pushing arm E, to the needle D, which has a longitudivnal groove, o?, in its rear face, to guide the cord and prevent it slipping off the needlepoint, and a stop, a", against which the front end of the U-shaped arm V, to be presently described, impinges, and thereby holds the cord straight in proper position to enter the groove a2.

F represents the main driving-shaft, which receives its' motion through a pulley or cog \vheel,f, operated by any suitable means.

The packer Gr, for packing the grain upon the gavel holding or supporting arms, consists vof two disks or wheels, one of which, H, is

keyed upon the inner end of the shaft F, and has pivoted to its face, at g, the arms or extensions h of the packer-arms l, the other disk, J, being journaled in the framing at i, eccentrically to the disk H, and having the ends of the packer-arms I pivoted at k to the inner face of the disk J, as shown. lt' desired, instead of-applying the pivot-pinsg and lc directly to the packer-arms, and then securing said pins within holes in the disks, said pins may be first applied to the disks themselves, and the packer-arms then. engaged therewith. Again, the arms 0r extensions h of the packerarms I may be of elbow form, as shown, or they may be of any other desired or convenient con. tour 0r shape, and they may extend from said arms in a reverse or in any other suitable direction from said arms. The -distance from pivot g to pivot h is equal to the distance from center to center of the disks or wheels H J. Upon each of the pivot-pins is formed a shoulder, l, which projects slightly beyond the arms or extensions, to prevent the binding upon and friction against said disks of said packer-arms. By thus eccentrically mounting the disks H ICL.

and J and constructing the upper ends of the packer-arms I with an arm or elbow-extension at their inner ends, and pivoting said arms to each disk, and mounting said disks with an equal distance between their centers and between the pivots g 7:, I secure a uniformity of action of said arms, and as said disks revolve said arms will retain a vertical or nearly vertical position and will revolve around each other, and on their upward rotation will be brought entirely within the circumference of said disks, thereby insuring the rotation of said arms free from contact with any of the operative parts ofthe machine.

By pivoting the packer-arms upon the disks or wheels and mounting said disks eccentrically, as shown, considerable leverage power will be imparted to said packer-arms during their rotation forward. rlhis is especially advantageous when they reach the position for operating upon the grain on the platform, as they are held perfectly rigid between the disks, and as they revolve with the disks they press the grain forward to the holdingarms with a steady force. l

.In the drawings I have shown the binder as provided with one packer only; but by extending the short shaft or pin t' one or more additional packers may be mounted thereon whenever it is desired to exert a forward pressure upon the grain at more than one point of its length. Loosely mounted upon the shaftF is a toothed wheel, m, which is held from longitudinal movement upon said shaft by sleeves o, and gears with the teeth of the drive-wheel K, which is keyed upon one end of a shaft, N, upon whose other end is mounted a disk, to be presently described, for operating the tyershaft and cord holding and cutting devices.

The gavel-discharging arms Xare mounted upon the shaft W. The gavel-supporting arms L are connected at p to the gavel-dischargin g arms X, so as to extend in a reverse direction therefrom, the object of which is that, as the gravel-supportingarms L recede and pass downward below the platform on the completion of the tying of the gavel, said arms X will ascend and come in contact with the gavel on its opposite side, and on the continued revolution of said shaft W said arms X will press the gavel forward and off the platform.

Within the lower end of each arm L isformed a slot, l. `By loosening the screws p said arms can be slid inward or outward, as desired, to adjust their position upon said shaft, and thereby increase or diminish the space between the arms L and the packers, and allow of gave-is of larger or smaller circumierenc being formed, as desired. f

Upon the inner face of the drive-wheel K isa cam, Y, the rim of which, as the drive-wheel revolves, is in contact with apin, q', on the inner tace of the hooked arm M. Upon this disk Y being revolved until the recess 1^ comes under the pin q', said pin.will drop down within said recess, and thereby bring the hooked outer end of the arm M into engagement with the upper arm of the clutch on the wheel m, and thereby hold all the operative parts ot' the machine, with the single exception of the packer, from rotation. Upon the grain being packed against the gavel-supportingarmsL by thepacker-arms, said arms will be forced backward, and as they are securely fastened to the shaft WV, said shaft W will thereby be correspondingly turned. The reverse rotation of this shaft W is prevented by a spring-pawl, s', which engages with a ratchetwheel, t', upon said shaft W. Upon the end of this shaft Wis keyed a cog-wheel, L, which meshes with a gear-wheel, n', journaled in the framing. Projecting from the inner face of this gear-wheel u' is a projection, o', which, as the gear-wheelu is, through the cog-wheel L, moved around the distance of one tooth, is forced against the downwardly-depending portion w' of the hooked arm M, pushing the same forward, and thereby tripping the hook, as shown in dotted lines, Fig. 3, and by means of a clutch mechanism, to be presently described, coupling the wheel m with the driving-shaft F, in order that. said wheel m may rotate and impart motion to the drivewheel K and parts connected therewith. The horizontal and vertical arms of the hook M have movement within staples gZ h2, which retain the same in proper position.

Projecting outwardly from the outer face ofA the gear-wheelul is a pin,f2, which rides upon the rim t2 of the disk la?, the oiiice of said pin while riding upon said rim being to hold the gear-wheel, and consequently also hold the toothed wheel Z and the shaft upon which are the gavel supporting and discharging arms, from movement until the recessed orcut-away portion Pof the rim i2 comes opposite said pin f2- Then at this moment the cogs of the gearwheel u andthe teeth of the rack m2 will mesh together, and as the gear-wheel u revolves it will turn the toothed wheel Z and cause the shaft W to revolve and operate the gavel supporting and discharging arms. The grain from the elevator falls upon the platform or apron Ain front of the packer G, and as the cogwheel f, which may be a chain-wheel ora band-pulley,or of other suitable construction, and revolved in any of the well-known ways, revolves, the shaft F is caused to revolve and carry with it the innerdisk or wheel,H, which in its turn carries around the outer disk ork wheel, J, and the packer-arms I, secured to said disks or wheels. As these arms I revolve they take hold of the grain lying upon the apron or platform A and propel it forward toward the gavel-supporting arms L, said forward movement of the grain being continued by the arms I until the pressure of the grain against the gavel-supporting arms L forces them back far enough to raise the hooked arm M from a clutch-armi), on the inner face of the gearwheel m. This arm NI is pivoted at its rear end to the fi'aming,and is held down at itsfree end in locking engagement with the armp of the clutch q, as shown in Fig. l5, by a plate- IOO ' ing coupled together, the continued rotation of said shaft will'cause said wheel to revolveand impart rotary motion to the drive-wheel K.

On the outerface of the drive-wheel K, and.

eccentrically thereon, is a stud or project-ion, b2. To this stud b2 is secured the upper end of a pitman, c2, which is composed of two short rods having rightand left screw -threads formed upon their inner ends,.said ends being coupled together by a sleeve, d2, by turning which in one direction the inner ends of said rods may be brought nearer together, and the vpitman thus shortened, and by turning said sleeve in the reverse direction said ends are pushed further apart, and the pitinan thereby lengthened. The lower end of this pitxnan is secured to a crank-arm, e2, whichis keyed upon the outer end of the rock-shaft B. Upon this rock-shaft B is mounted the needle D.

'lhe compressor T consists of two curved arms, U U, joined togetheratornearone end by a pin or stud, m', and at the opposite end by a pin or stud, m3. The pin m' preferably has a roller mounted thereon to avoid friction on the needle, and at this end the curved arms ot' the compressor arepivoted upon a transverse shaft, a', having bearings within the platform or withv in slotted plates, o', attached to the under side thereof. By-securing these ends of the arms U U within the slots 02, the needle, on passing up, will press against the pin m3 and push such lower ends forward within theslots, thereby diminishing the space between the compressor and the gavel -holding arms. Upon the retraction of the needle the recessed rear edges m of the arms U ofthe compressor are forced. against the shaft B, which causes their pivoted ends to move rearwardly in the slots sufficient ly to allow of such arms U passing down beneath the platform withoutcoming in contact with and binding against the shaft B, as would be the case were the arms U pivoted without capability of horizontal movement.

E represents a curved arm, which may be formed solid with the needle-arm or formed separately therefrom and secured at its lower end thereto. e, as shown, through which the cord passes from the spool to the groove a2 and to the eye of the needle, and near its upper end this arm E passes betweenthe cheeks or arms U ofthe compressor and rests against the rear face of the pin or stud m3. The effect of this arrange-- ment is that as the drive-wheel K revolves the shaft B is turned, carrying with it the needle l), and as said needle passes upward and for- This arm has eyes or staples c ward the arm E thereon will press against the pin or stud m3 and force the compressor for ward, thereby compressing the grain up to and upon the gavel-supporting arms L, and on the needle being retracted, after the bundling and tying of the gavel are completed, the rearward motion of said needle will cause its arm to press against the front face of the pin or stud m3 and 'carry the compressor down with it below the platform A.

A-ttached to the arm E, or formed solid therewith, with its forward end resting or abutting against a stop at ax x, on the rear of the needlearm, for the purpose hereinbefore described,

`is a bow or Dshaped arm, V, which serves as a guard or fence to hold back the grain Afrom the needle during the operation of compressing and tying the gavel. As the packer is in constant operation, the tendency of its arms is to continuously press forward the grain upon thc platform, and without such arm V the grain would be pressed against the needle and compressor, and thereby impede their action and become tangled up with the gavel being bound. By the employment of this arm V the grain upon the platform A is e'ectually kept back from the needle and compressor and a clear Avspace left within which they they can work.

At the same time that wheel K causes the forward motion ofthe needle it also rotates the shaft N, at whose opposite end is secured a cam and rack wheel, 0. Ou therim or periphery of this cam and rack Wheel O is an arm or pin, c, having segment on its outer end, which, when the needle has passed forward so as to place the end ofthe cord across or'between the arms of the cord-holder .fr by the continued revolution of said cam and rack wheel O, comes in contact with-the toothed disk y' and turns the cord-holder w around the distance of one arm, thereby causing, the latter to clamp and I hold the cord taut until the knot is formed, when the knife Sis turned by the arm h and the cord cnt and thrown, in the manner hereinafter described.

Projecting from the outer face of the cam and rack wheel O is a lug or projection, upon which is sleeved a roller, n2.

The cord-tyer l? consists of a shaft, a3, having a finger, a, and a sleeve, a5, having a finger, a6. Upon the sleeve a5 is formeda cam. c", which, when the tyer is rotated to form the knot by the segment on the cam 'and rack wheel O engaging with the cog-wheel on the tyer-shaft, rides upon saidroller. The sleeve and its finger a6 are thereby raised to admit the entrance between thefingers a4 and a6 of that part of the cord at the rear of the knot, and when the olfset als on the cam a7 is in line with the roller n2 the free end of the spring a9, which rests upon the top of said cam, will force thesleeve down, and thereby clamp the cord between the two fingers. This spring is -secured at its rear end by a screw, al, to the IOS said spring increased or diminished as it is desired to force the sleeve down more or less quickly and firmly.

The object of arranging a roller for the camV al to travel upon is that thereby the tycr may rotate with greater ease and less friction than would be the case were said cam arranged to Y ride upon a pin or stud on which there was no pendent vertical movement upon said shaft.

Upon the inner edge ol' the wheel() is a segmental rack, y, which is so arranged upon said wheel that it shall gear with the teeth upon the pinion or toothed wheel zon the top of the Iyer-shalt at the time that the segment on the pin c on the wheel 0 operates upon the cordholder. The teeth on the segment y are of a number sufficient to revolve the cog-wheel z once. As the cog-wheel z revolves it carries the shaft of the tyer I.

A cam-groove, a', is formed in the circumference ot' the wheel O, within which works a pin, b', on one end ot' an arm, Q. This arm Q is centrally pivoted at c to a link, d', connecting said arm Q with arm It, and has a pivot or pin, e', which rests within the slotf in the arm 1i. By this construction, upon the revolution ot' the wheel O bringing the pin b into engagement with the inclined portion g of the cam-groove in the wheel O, the arm Q will draw the slotted end of the arm R inward, and consequently force the front end, h', of the arm R and the hook-shaped end t" outward. As the end It moves outward it comes in contact with the lugj on the knife S and pushes said knife partly around, so that the sharp edge k' otsaid knife shall cnt with a shearing action against the frame on which it is mounted, and thus sever that portion of the cord lying across the edge of the frame and allow ot' the removal of the tied gavel. As the needle begins its return movement the end 71, of the arm R returns to its normal position, and as it returns it comes in contact with the lug l on the knife S and pushes said knife back in readiness for the next cutting movement. The hook-shaped end 'i' on the arm R pushes the cord away after the tying operation.

In Fig. ll is shown a perspective View ofthe cam and rack wheel with a part removed to show its internal construction. The inner face ot' this wheel has an outer circumferential rim, 2, and inner circumferential tlat face, 3, recessed at 4, a central recessed portion, 5, and a disk, 6, for holding said wheel upon its shaft.

In Fig. 12, 7 represents a plate or disk,which is secured to the framing and lits within or npon the face of the wheel O, (shown in Fig. 1l.) 0n this plate 7 is aiiat face, 8, with which the ilat face comes in contact and upon which it revolves. 9 represents a central rim which tits within the recess 5. 10 represents a circular orifice through which the roller n2 upon the shaft projects to engage with the cam on the Sleeve of the tyer. The opposite face of this plate 7 is recessed to receive the tyer,which is embraced on the opposite side by osets l1 on the plate 12. A recess, 13, is formed in this plate topermit of the free end of the spring agengaging the cam on the tyer-sleeve. Resting upon thetopol' thisplate l2,andextendingacross the rim ofthe plate 7, which is cut away at that point, as shown,.to allow of the free movement thereof, is a disk, 14, which is mounted on the tyer-shaft and revolves therewith. This disk 14 is cut away or liattened at 15. Upon this plate 7 being secured to the face ofthe wheel O, this flattened portion 15 will rest against the ilat l'ace 3. and, on said wheel() revolving, said face 3 will travel continuously across this l'lattened portion untilthesegnienton the wheel engages with the cog wheel on the tyer-shalt. Immediately on the segment turning the cog or pinion on the tyer-shaft, said disk or collar 14 will revolve, and the circular portion of its rim or edge will then.come opposite to the recess 4 in the face of the wheel O, and thereby admit ofthe tyer freely revolving until the flattened portion l5 again comes in contact with the ilat face 3 of the wheel O.

Attached to the rear end of the framing are two plates, b3 b3. To thein ner face of each plate is secured one end of a plate-spring, b4, with its free end extending down toward thelower ends ot' said plates. The cord holder or wheel an is pivoted within the lower ends ot' these plates b3, so that its arms w may revolve vertically between the free ends ofthe springs b4. Upon the needle with cord threaded thereon advancing, the forward portion of said cord will pass across and restupon said wheel within the space between the arms that is then in alignment with the needle. Then as the wheel() revolves the segment on the end of the arm of pin c wil engage with the teeth ot' the disk y on the wheel rv, and thereby turn said wheel around sufficiently to cause the arms w to move forward and carry the cord to and between the freeends of the springs b4, which will then clamp the cord and hold the same iirmly between them and the arm holding the cord. The binding or clamping power of said springs b4 upon said cord, and also upon the wheel w, can be regulated by a binding-screw, b", by tightening which the plates b3 can be forced nearer together to grip the cord and wheel more firmly, or by loosening said screw b" the friction upon such cord and wheel can be diminished, as 0ecaslon may require.

Upon the rear face ot' the outer plate, b3, are a spring-pawl and ratchet, 118, said ratchet being keyed to the outer end of the shaft or pivot upon which the wheel rotates, for the purpose ot' preventing rearward motion of said wheel which is very necessary, as without some such arrangement said wheel might be forced backward, and thereby cause the pre- IIO IIS

273.325 Y l '5 l mature release of the cord held thereby, and thus entanglc the cord and cause a derangement of someof the operative parts of the machine. l

The knife S is pivoted to the outer face of the inner plate, b3, by a screw, b9. A frictionspring may be placed under the head of said screw, so as to insure the knife being held steadily in whichever position it is turned. This knife has a circular rear edge to allow of the cord readily slippingaround or across the same on its passage to the cord-holding wheel.

A' represents a plate or shield, attached at each end to suitable hangers on o'r otherwise secured to the framing, for the purpose of fending or shielding the tying mechanism from grain. A longitudinal slot, B', is formed in said plate or shield to admit lof the passage therethrough of the needle-arm and its attachments. y

C, Fig. 2, representsv a bow-shaped arm, which is secured at one end to the edge of the platform-A and at its outer end to the under side thereof. As the gavel is pushed off by the arms X it will drop upon this arm C' and fall away from the line of movement of said arms X.'

The operation of the machine is as follows:

The needle D having been threaded, the pulley or wheelf is connectedo the ordinary driving mechanism, and on motion therefrom being imparted to said wheel or pulley the shaft F will revolve and carry with it the wheel m, and cause the same to revolve the drive-wheel K. By means of the pitman c2 motion is then imparted to the rock-shaft-B, upon which the needle D is mounted. As this shaft B rocks it carries the needle up and forward until the loose end of the cord is laid across the cordholding wheel. As the wheel O revolves the segment on the pin engages with the teeth on the cord-holdin g disk or wheel w and turns the same around, thereby carrying the cord between the cord-clamping plateslf b4, where it is tightly held. The continued revolution of the drive-wheel will then cause the retraction of the needle below the platform. Said drivewheel then continues its revolution until the recess r comes opposite the pin q', when said pin q will drop down into such recessed portion r and cause the hooked arm M to engage with the arm p on the clutch, and thereby ,hold the coupling-wheel m, and consequently drive-wheel K and parts connected therewith, from rotation. The cordbeing thus placed in position, the grain is then allowed to fall upon the platform A from the elevator in front of the needle, and as the packer G revolves the arms I press such grain forward and pack it upon the gavel-supportin g arms L. As the grain packs against the gavel-supporting arms L said arms will be slightly pressed back. This willcanse the shaftto turn partly around and move the wheel t one tooth. As wheel t moves'around the distance of one tooth it causes the gear-wheel u to move the distance of one tooth also, and thereby bring the pin on its outer face into frictional contact with the rim t2, and at the` same time causes the pin fz on the opposite side of said wheel u to press against the lower end of the arm M, rand thereby raise the hooked end of said arm and release the clutch. The clutch having .thus

been released, the wheel 'm revolves and imparts motion to the drive-wheel K, which in turn rotates the shaft upon which the cam and rack wheel O is mounted and operates the rock-shaft B, carrying the needle-arm and its attach ments. As the shaft revolves the needle ascends and carries forward the compressor, which compresses the grain, places the cord across the fingers of the tyer, and'presents the forward portion of the threaded cord to the arms w. At the same time the segment on the arm u engages with the cog-wheel on the disk w and causes the arms w to move around one step to grasp the cord. Vhile this operation is being effected the segment on the wheel O engages with the cog-wheel or pinion on the top of the tyer-shaft and causes the tyer to rotate and knot the cord. As thetyer rotates, the cam upon the tyer-sleeve comes'in contact with the roller projecting from the wheel O, and rides upward thereon, thereby opening the respective ngers on' the tyershaft and sleeve, and allowing` them as theyr revolve to pass on either side of the cord. The tyer having made one complete revolution,

the sleeve drops down, being aided in such downward movement by the spring pressing upon the top edge of the cam on said sleeve, and holds the cord between the two iingers. The cam-groove in the wheel O then operates on the arm R and pushes the finger at the front end, h., against the lug or projection on the knife, thereby causing said knife Sto turn and cut the cord. movement ot' the front end of the arm R then .causes the hook i' to push the cord away and free it from the tyer-hooks. Then, as the drivewheel continues its rotation, the armR is returned to its position of rest, the needle and compressor are retracted, the shafty W is rotated, and the gavel-supporting and gavel-discharging arms are revolved, and the bound gavel pushed oft' the platform.

Having thus described my invention, what I claim-.therein is ll. The packer G, consisting of the disk or.
