SPECIFICATION formingpart of .l'aetters Patent No. 708,002, dated September 2, 1902. Application tiled September 11, 1901. Serial No. 75,007. (No model.)

It has for its object to provide means for' causing the binding and packing mechanisms to intermit alternately in their operation and means whereby the pressure on the packers sets the binding mechanism in motion.

It has for its further object to provide l means for adjusting the needle relative to the knotter Without changing its relation to the deck.

In the drawings, Figure lis a side elevation of such parts of a grain-binder as necessary to illustrate my invention. Fig. 2 is a plan View of parts shown in Fig. 1. Fig. 3 is a detail elevation of the means for intermit-` tently actuating the binding mechanism. Fig. et is a detail elevation of the means for intermittently actuating the packers. Fig. 5 is an elevation of a portion of the binding mechanism, showing the means for adjusting the needle relative to the knotter. an elevation of a portion of the parts shown in Fig. 5, showing that the relation of the needle to the deck does not change as it is adjusted relative to the knotter. Fig.`7 is a perspective View of the vibrating trip-arm. Fig. S is a perspective View of the packerlink support. view of a portion of the binder-frame, showing the bevel-gears inclosed in their cases.

The binder-frame A, the binder-pipe B, the

tie b, and the supports C and D form the ordinary frameworkot' an automatic grainbinder. This framework is mounted upon the harvester (not here shown)y by means 'of suitable supports in the ordinary manner. The binder-frame A is connected to the binderpipe B by means of the support C and the- Fig. 9 is a partial sectionalv tightly iitted thel needle-shaft L. The support D is secured at'one end to said needleshaft and at the other end to the binderpipe B.

The continuously-rotating driving-shaft E, which receives its motion from the tractionwheel through the intermediacy of the ordinary gearing, is journaled in the boxes c and d of the supports Cand D. Secured to the driving-shaft E near its inner end is the spur-pinion E', and mounted upon said driving-shaft and adapted to vibrate thereon is the Vibrating hanger F. (Best shown in Figs. 2 and 4.) Journaled in the vibrating hanger F and in constant mesh with the spur-pinion E is the intermediate pinion F. To the sleeve or hub f is secured the operating-arm f', which is adapted to beengaged by a roller or cam on the needle-arm, as will be described later. The packer-shaft Gr, having the packercranks g and g, is journaled in the self-alining boxes c and d in the supports C and D. Secured to said packer-shaft near its inner end is the spur-gear G'. Intermittent rotation is imparted to said spur-gear by the intermediate pinion F', which is adapted to mesh 'intermittently therewith. Journaled upon the packer-cranks g and g are the usual packers-H and H, which have their lower Vends held in a definite relation to some normally tixed point by the ordinary packerlinks h and h. It is customary to pivot one end of the packer-links to a fixed point in the binder-framework, but, as here shown, they are pivoted in the'packer-link support h',

which in turn is pivoted on a stud on the support D, but which is normally held in a fixed relation with the framework of the binder.

ment is eectual in throwing the binding mechanism into gear, as will be hereinafter described.

In suitablefbearings in the binder-frame A is journaled the binder driving-shaft I,v

th rough which motion is imparted to the knot- :ter-sha1 t I through the intermediacy of the cross-shaft I2 and the miter-gears and 'i and miter-gears t" and 7l'. To the knotter-shaft I is secured the ordinary kuotteroperating wheel I4, which actuates the knotting devices. On the inner end of said binder driving-shaft is the spur-gear I3, provided on the outer side with the cam Z2 and the delay-surface Z3.

Mounted upon the driving-shaft E near its inner end and adapted to vibrate thereon is the trip-arm J. In the yoke j of said triparm is journaled the intermediate pinion J', which meshes constantly with the spur-pinion E' and is adapted to mesh intermittently with the spur-gear I3. The trip-arm J is counected to the packer-link support 71,' by means of the trip-linkj. On the upper end of said trip-arm and in one part therewith is the tripcamj2.

Pivoted in suitable lugs OZ and a of the binder-frame is the trip-shaft K. Secured to the inner end of said trip-shaft is the tripstop K', which is provided with the antifriction-roller k, adapted normally to engage the trip-cam 3'2. In one part with the trip-stop K' is the actuating-arm K2. The outer end of the trip-shaft is provided with the crankarm 7c', to which is pivoted the slide 702. Pivotally secured to the tie Z) is the trip-spring rod twhich is adapted to move freely through the slide k2. Upon this rod is the trip-spring 7a4, one end of which bears against the slide k2 and the other against a threaded adjusting-nut on the end of said trip-spring rod.

It will be noticed that the actuating-arm K2 of the trip-stop is adapted to project diagonally above the deck in a position to be engaged by the grain to be bound. During the packing of the grain when the pressure on the actuating arm produced by the packers reaches a certain point determined by the tension ou the trip-springk4 it is pressed down against the action of said trip-spring and the trip-stop K' raised, so that its antifrictionroller is out of engagement with the trip-cam j2. This disengagement leaves the trip-arm J free to move on its axis on the driving-shaft. The thrust on the packer-links h and h, due to the same pressure on the packers which is eectual in disengaging the trip-stop from the trip-cam, moves the packer-link support 7L' upon its pivot, which in turn through the agency of the trip-linkj' moves the trip-arm J upon its axis, whereby the intermediate pinion J', carried thereby, is thrown into mesh with the spur-gear I3 on the bindershaft and the binding mechanism is actuated, as above referred to. It will be seen that the effective arm through which the force of the trip-spring acts is greater before the trip-stop is disengaged from the trip-cam than afterward. In other words, when the mechanism is tripped the trip-spring acts nearer the deadcenter of the crank-arm of the trip-shaft than before. In this manner considerable pressure is required to trip the mechanism, so that the bundles may be bound tightly; but when once tripped little resistance is offered to theirdischarge. At a properly-timed point the spur-gear I3 is mutilated by filling or partially filling the space between two or more teeth. When the intermediate pinion J shall have driven said spur-gear through one revolution, one or more teeth of said intermediate pinion engage the mutilation. The proportion of said mutilation is such that when it is thus engaged said intermediate pinion is raised and the trip-arm J, in which it is mounted, moved on its axis a suicient amount to carry the trip-camj2 beyond the dead-center of the antifriction-roller 7c of the trip-stop. Through the agency of the trip-spring 7a4 said antifriction-roller is forced into its seat in said trip-cam, whereby said trip-arm is moved on its axis a sufficient additional amount to carry said intermediate pinion entirely out of mesh with said spur-gear. When said intermediate pinion is once thrown out of engagement with said spur-gear, it remains there, and said spur-gear remains at rest until suicient pressure is again brought upon the packers, when the operation is repeated.

J ournaled upon the needle-shaft L is the needle L', to the hub Z of which in one part therewith is secured the arm Z'. Pivoted to said arm is the adjustable bell-crank Z2, which is secured in a normally fixed position relative thereto by the adjusting-bolt Z3, with its lock-nuts engaging a lug Z4 onthe needle-hub. The needle-pitman Z5 has one end pivoted in said bell-crank and the other end in the spurgear I2. As the spur-gear I3 is driven through its cycle by the intermediate pinion J', thereby driving the binding mechanism, as above described, the needle L' is caused to oscillate on its shaft through the intermediacy of the needle-pitman Zand the adjustable bell-crank Z2, whereby the bundle is compressed and the cord carried to the knotting device in the usual manner. By means of the adjustingbolt Z3, thereby shortening or lengthening the effective length of the arm Z', the needle may be readily adjusted relative to the knotting device to compensate for variations in man ufacture or for any other purpose without changing its relation to the deck, as shown in Figs. 5 and 6. Devices heretofore foradjusting the oscillation of the needle have been such that when it was found necessary to move the needle farther at the forward end of its oscillation it would be moved less at the rear end. By this means the point of the needle may be left projecting above the deck to interfere with the passage of the grain. The device herein described and illustrated overcomes this objection, since the needle always returns to the same position under the deck, or about so, regardless of its adjustment relative to the knotter.

Pivoted upon the needleshaftL is the compresser-arm M, to which is secured the compressor-hook m, and pivoted in a like manner is the compressor-actuating arm M. Interposed between said compressor-arm and the actuating-arm is the compressor-spring IOO IIO

fm', which produces a yielding pressure upon the bundle. The position of saidcompressor is determined by the stop d, located in this instance upon the support D, which stop is adapted to engage the lug m3 upon the com- A properlytimed cam 2 is located upon the spur-gear I8 and is adapted to engage an antifrictionroller m2 on the actuating-arm M'. When the bundle has been bound, the antifrictionroller m2is disengaged from the delay-surface 723 of the cam t2 and the compressor-hook dropped on its pivot to permit the discharge of the bundle, after which it is again raised to its normal position by the cam 2'2.

Upon the arm of the needle L is secured a roller or cam l?, which is adapted to engage the operating-arm f'of the vibrating hanger F, as above referred to. During the packing of the bundle the intermediate pinion F' is held in mesh with the spur-gear G' by the spring f2 or other suitable means; but when the needle rises in the operation ofbinding the roller or cam Z6 engages the operating-arm z f', and thereby moves the vibrating hanger on Yits pivot and carries the intermediate pinion out of mesh with the spur-gear G', -thus causing the packers to intermit in their operation alternately with the binding mechanism. When the bundle has been bound and the needle recedes, the vibratin g hanger, through the action of the spring f2 again carries the intermediate pinion F into'mesh'with the s ur-Ofear G', thereb actuatinf` the acke'rs.

P e Y e P It Will be seen from the relative positions of the axes of the intermediate pinionsF and J' to the axes of the gears E and G' andE and I3 of their respective trains and the direction of rotation of the driver E that when once said pinions are thrown into mesh the tendency is to remain so and to be forced in more deeply. To prevent their meshing too closely together, each of the two trains is provided withpitch-line shrouds which are adapted to roll together, thus forming automatic stops.

Heretofore the gearing fordriving the knotter-shafthas been outside the binder-frame; More or less trouble has been experienced by straw getting into it and being Wound up. Here a binder-frame is provided with cases for inclosing said gearing.k At the intersection of the horizontalmembers of the binderframe Arwith thetransverse member are the cases a3 and a4, which inclose,respective1y,` the ruiter-gears z' Vand The openings of said casings are closed by the coverings a5 and a5. In this-mannerthe gearing is completely inclosed and protected fromv all foreign substances, thus making the life of the gears longer and their operation less troublesome. l

The successful operationof this invention" does not depend upon the use of the packerstopping device herein shown and illustrated. The dev ice for accomplishing this end', pat- I ented to me July 2, 1901, No. 677,553,l can quite as readily be used instead in combination with the other parts described. Hence I do -not wish to limit myself to the means for stopping the packers as above described.l
