To all whom t may concern.- y

Be it known that I, GEORGE G. HUNT, a citizen of the United States, residing at Bristol, inthe county of Kendall and State of Illinois, have invented a new and useful Improvement in Grain-Binders, of which the following used.` I attain this object bythe mechanism illustrated in the accompanying drawings,fin which- Figure l` is a side view of my invention looking from the stubble side of the machine.

Fig. L is a sectional rear view on the line y, y Fig. l of a part of the binder frame with driving sprocket wheel mounted thereon. Fig. 5 is a sectional view from the rear on the line m, on Fig. l showing the trip mechanism. Fig. 6 is a view of apart of the trip mechanism, looking from the stubble side. Fig. 7 is a longitudinal sectional view of the compressor body showing its interior. Fig. 8 is a modification showing a front view of those parts of myinvention designed to operate the needle when mounted on a rock shaft driven from the front. Fig. 9 is a plan of parts shown in Fig. 8.

In Figs. 8 and 9, similar letters and characters of reference indicate like parts in the n two figures.

to be supported thereon.

The knotter head may be of any usual form and is not shown.

In a lower horizontal arm A2, is mounted loosely but firmly the front portion of a needle shaft A4. The rear portion of the needle shaft `A4, is supported in a bearing b2, attached to the end of a cross bar B. The opposite end of the cross bar B, embraces a longitudinal tubular bar B3, and is firmly attached thereto. Two other cross-bars B-B2, are similarly attached to the bar B3, and, at their opposite ends are forked to embrace the lugs A3 on the horizontal arm `A2. The three cross bars B,-B,-B`, are identical in form, and cast from the same pattern. The lugs A3, and forked part of cross bars B'-B2, have corresponding holes to admit bolts which clamp the bars and frame firmly together. A

The lower part of the forks h, of the cross bars B--B'-B2 project stubbleward and are provided with bolt holes J4, J6 for the attachment of packer link pivots.

A needle I is rigidly attached to the shaft A4, in close proximity to the rearend of `the arm A2. The shaft A4, in this case, is subjected to no torsional strain,` and may therefore be of only sulicient strength to serve as a pivot for the needle and to helpsupport the outer end of the bar B, which supports the rear end of the deck or grain table.

The binder frame is provided with hangers terminating in bearings A51-A6, in which is mounted a shaft O, to the front end of which is rigidly attached a gear Wheel K, and, to its rear end acrank wheel O13, is similarly attached. The crank wheel C13, is provided with a crank pin O7, upon its rear side, and upon its front side it has a short projecting pin F. The wheel C13 is cam shaped as shown in Fig. 3. Another wheel C3, is rigidly attached to the shaft O, in the rear of, and in close proximity to the wheel O13. The wheel C3, is cut away as shown at f4, (see Fig. 5) and is bored to receive the pin 1C, of a driving dog O4, which is located on the front side of the wheel O3, the hub of the wheel forming a stop against which the dog C4 rests as in Fig. 5. The dog O4 is firmly attached to the pin 1C, or it may be integral therewith. l

Upon the pin 1C, at the rear side of the wheel O3, is rigidly attached an arm or lever 1C", terminating in a part lO', bent to be at a right to the front side of the lever 05.

angle to the body of the arm or lever 104. A light coiled spring S, embraces the pin 10,f the ends of the wire forming the spring resting under tension as shown in Fig. 5; having one end against the part 10', of the arm 101, and the opposite end against the shaft 0, thereby acting constantly to rock the dog 04, away from the hub of the Wheel C3, into the path of a driving pin 02, on the wheel 0';

A trip lever 05, is pivoted near its center upon a pin c. The outer part of said lever is curved upward to allow the grain to be packed against it by the packers J. The inner portion extends downward and inward, terminating in an angular part 012. An angular lever or support 06, is pivoted at its upper end upon the same pin c, in close proximity The lower part of the lever 06, lies a short distance below the lever 05, and is provided with a rearwardly projecting flange d, upon which rests the lower end of a coiled spring 08, which embraces a rod 07. The rod 07 tits loosely at its lower end in an aperture in the `flange d, and is conned therein by a pin 016. The upper part of the rod 07 is threaded for the reception of a nut 015, which presses against the upper end of the spring 08. The upper end of the rod 07 is pivoted to a lug 09, on the lever 05 by a pin 011.

Near the angle of the lever 06, and upon its rear side, is a pin e upon which is mounted a roller 010, that rests upon the periphery of the wheel 03, thereby supporting the lever 05.

The nut 015, may be adjusted to cause more or less resistance to the pressure of the grain against the lever 05, thereby allowing greater or smaller bundles io be made as desired.

The angular part 012, of the lever 05, when in its initial position, (see Fig. 5) lies in the path of the angular part l0 of the dog lever 104, so that as the wheel 03 completes its revolution the part 10 engages or abuts against the part 012, thereby forcing the dog 04 into the position shown in Fig. 4, and out of engagement with the driving pinv 02, on the wheel 0.

In Fig. 4, the driving dog 01, is not intended to be shown as a part of the wheel 0, but shows its relative position to wheel 0 and its driving pins 02.

For imparting motion to the needle l, I use a toggle jointed lever H, the inner end being pivoted on the bar B2, for convenience. The outer end H5 is provided with a slot H11, having a lateral flange or rib H8 surrounding it for wearing surface and for strength.. Two links H8 connect the lever H, between its ends with the needle AI, by pin joints L12-H4, and the outer end H5, is connected by the crank pin 07, and its roller R, in the slot H5, to the wheel 015. The inner part of the lever H, is

provided with a slot I-l through which the needle I, vibrates in binding, and a rib H9, connecting the iiange H8, with the body part of the lever stiensthe structure. i

The compressor may be described as fol` lows: A hollow cylindrical bar E, provided with a pendent lug E21, and forked at its inner end to impart stability, is pivoted on a lug A7, on the binder frame, a pin e passing horizontally through the lug A7 and fork of the bar E. Upon the bar E, is mounted a hollow cylinder E2 with open ends which is adapted to slide on the bar E. The cylinder E2, is provided with an upwardly projecting curved arm E', which is opposite to, and in the same vertical plane as the needle l. A pin E3 passes through the pa-rts E-E2 from top to bottom, fitting tightly in the part E2,

and loosely in'a slot E6, in the bar E thereby allowing the pin to move therein and allow the'part E2, to slide on the bar E. The hollow bar E, contains a spring F having its in- Y ner end abutting against the pin E3, and held under compression by a pin E7, in thev outer end of the bar E. Upon the rear side of thev lug E31, is a pin E4 upon which is mounted a roller E8, which rests upon the periphery of the crank wheel 013. The lug E21 terminates .in a tooth f2, which lies in the path of the pin f, on the wheel 013.

Upon a stud attached to the frame A is a gear wheel K2, having the same number of teeth as and meshing with the wheel K. The wheel K2, is secured to a sprocket wheel K3,- the two wheels being preferably integral, or

cast in one piece. The sprocket wheel K2, and f the sprocket wheel K4, have an equal number of teeth, and are connected by a chain K5, which transmits motion to the shaft a., and rotates it in unison with the shaft 0.

A' double crank G2, for driving the packers is mounted in hangers B5, (see Fig. 3,) integral Vwith the'bars 13g-YB. Y

A sprocket wheel G2, is rigidly attached to the front end of the crank G2, and connects it with adriving shaft G, the front end of which is supported by a hanger similar to those supporting the crank.

A chain G4, connects the sprocket wheel G2, to the wheel 0', and is thereby kept in constant motion. v

A packer J, is connected to the crank G2, bya box and strap J The tail of the packer J is connected to one end of a packer 'link J2, by a pin joint J, and the opposite end of the said link is pivoted to the frame at the point J 3.

As the packers form n.0 part of my invention they are only shown in'Fig. 3, for the purpose of showing the form and relative position ofthe parts. A bolt hole J4, in the member b, of the bar B', is for the attachment of the packer link pivot for the front packer, and the same member of the barB is similarly provided for the attachment of the rear packer link pivot.

The vhole J 6, in the bar B2 is utilized for the insertion of a bolt for confining the deck'or grain table,-which forming no part of myv invention isnot shown. y

If desirable to attach a third packer, then the hole J 6 may be used in a similar. manner and for the same purpose as the correspondling holes in the bars B B', the same bolt serving for both purposes.

The operation of the mechanism described is as follows: The packers J, carry the grain little by little against the compressorarm E until the desired amount to form a bundle is in the receptacle, when the pressure against the arm C5, overcomes the resistance of the spring C8, and the arm C5, yields, and, moving on the pin e, the part C12, rises out of engagement with the part 1C of the lever 1C4, which, through the instrumentality of the spring s, carries the dog C4, into the path of the nearest driving pin C2, on the wheel C. C4, instantlyengages said pin, and motion is thereby communicated to the wheel G3, which j continues until one revolution has been made.

`As the wheel C13, moves in the direction of the arrow, the crank pin C?, slides in the slot Ils, but, at the same time carries the free part, or outer end H5, of the toggle-jointed lever H,

with it, and the needle I,-being connected as described-moving upward on its pivot,

stops the inflowing grain. When one quarter of a revolution of the crank pin C7, has been made, its position is at the end of the slot H6 nearest the pivot B3, and for this reason `the movement of the toggle jointed lever H has been the most rapid; and as the crank pin C7 continues its rotation and slides to ward the outer, or opposite end of the slot H6, the movement of the toggle jointed lever j H and needle I, becomes slower in a geometrical ratio until the extreme forward movement (represented by dotted lines in Fig. 3) of the needle has been reached, and the crank pin has arrived at the point indicated by the dotted lines in the same figure. At this time the toggle jointed lever H is extended into nearly a straight line between its pivot on the bar B3, and its connection with the needle I,- and the force being applied upon the needle in nearly a right line toward the center of the bundle, the extreme forward movement of the needle has been reached with precision,

. and with little strain upon either crank pin or needle, whereby the troublesome choking of the binder, and consequent `sliding of the drive wheel of the harvester is avoided. As the wheel C13, moves from its `initial position, its cam shaped rim, pressing against the roller 1 E8, moves the compressor arm E', toward the bundle. t quite slow, and until the needle Lbegins to At first the motion of the arm E', is

tying,`thereby relieving the cord of an unc necessary strain.

At the time the knot is tying, the compressor with its arm E', is at the position shown by dotted lines in Fig.` 3; but

c this position of the arm E', may vary by so The dog much as a large or small bundle moves the cylinder E2, outward against the force of the spring F, during the compressing process' At the time the needle, and other connected parts, have arrived at the position represented by dotted lines in Fig. 3, the bundle is nearlyready to be discharged, but in the form of cam shown in Fig. 3, the wheel C13, must move a farther distance, (approximately that between the roller E8, and crank pin in dotted lines) before the crank pin passes the roller and allows the latter to drop into the cut away part of the Wheel C13. As the arm E', drops ont of the Way of the discharging bundle, its upper end is just beneath the table or deck, and the roller E8, has

moved about the center e, untilsaid roller has passed a straight line t, connecting the centers of the shaft C, of the cam wheel C13, and the pin e. When the roller E8, is in the last mentioned position, the cam, or its shoulder y f 5, can not readily engage with the roller E8, to return it-to its initial position, but the pin f,engages the part f2, on the lug E3', and moves it outward past the aforesaid straight line 2f, when the shoulder f5, engages with the roller, and moves it until the rim of the wheel C13, moves under the roller, leaving it in its initial position as the wheel C13, stops.

In Figs. 8, and 9, the upright part of the binder frame is marked A, in an arm` A2, of which is mounted the needle shaft A4.

To the rear end of the shaft A4', the needle I, is securely attached by a key and pin. Upon the front end of the shaft A4', a crank N, having a crank pin O2, is also securely attached by a key and pin.

The outer end of the'crank N, is, for con venience provided with a slot N, in which one end of a link Q, is pivoted by a pin O2. The opposite end of the link Q,is pivoted in the forked end of a vibrating lever or bar O, by a pin O. The forked end of the lever also receives the upper end of a pitman OS upon the same pin O.

The inner end of the lever or bar O, is for convenience pivoted on a bar B3, which is attached to the frame of the harvester, but the position of the pivot may be changed within limits to meet a variation in form of binder.

The lower end of the pitman O3, is attached to a crank Cb, by a crank pin Cd. A shaft Ca, to the front end of which the crank Cb, is securely attached, is mounted in the lower part A, of the binder frame, and securely attached to the shaft Ca, is a gear wheel T.` Another gear wheel T having an equal number of teeth, is mounted on a shaft C, on the binder frame so that the gear Wheels T,- T', mesh together. The shaft C receives motion from a constantly running part as the packer shaft. As the movements of the toggle jointed lever have been already described, it is not considered necessary to describe the movements of the modified form contained in Figs. S and 9, above described.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isv l. ln a grain binder the combination of the frame having a binding arm or needle pivoted to said frame and vibratable thereon, a lever pivoted at its inner end to the binder frame and having a slot in its outer portion for the reception of a friction roller and crank pin of a driving crank, a link hinged at one end to the body of the needle and its opposite end hinged to the lever between its ends, and a driving crank mounted on a driving shaft of the binder, said crank having its pinL and friction roller in the slot of the outer part of the pivoted lever, all arranged in the manner as and' for the purpose hereinbefore set forth.

2, In a grain binder the combination of a vibratable binding armor needle pivoted by a shaft to the binder frame, the shaft itself lying in a fore and att position, a lever pivotally connected to the needle by a link, the inn ner end of said lever being pivoted to the binder frame outside the needle or toward the elevating mechanism in such a manner that When the lever and link are not exed, and the full forceof the lever is exerted upon the needle to compress the bundle the three pivots connecting the lever toy the vneedle and to the binder frame are in aright line or nearly so, a shaft mounted onrthe frame parallel with the needle shaft and driven from the motive power ot' the machine, and a crank mounted on said shaft and connected by suitable means to the Vlever whereby a vibratory motion is imparted to the lever and needle, at the same time yielding a compound leverage upon the needle by the crank passing its center at the instant the lever and its link are fully extended, all the parte being arranged substantially as hereinbefore specitied.
