BUNDLE-CARRIER.

Specification of Letters Patent.

Application led March 11, 1908.

Patented Jan. 26, 1909.

Serial No. 420,391.

To all whom it may concern:

Be it known that I, Jos Tnorrnn, a subject of the King of Great Britain, residing at Sevilla, Spain, have invented a new and useful Improvement in Bundle-Carriers, of which the following is a specification.

This invention relates more particularly to improvements in bundle carriers for selfbinding grain harvesters of that type in which the carrier is arranged to receive the bundles of grain as they pass from the binding mechanism and hold the same until a pre determined number of bundles have accumulated thereon, and then to automatically dump these bundles and return to its receiving position.

One object of this invention is to provide a practical and eflicient carrier of this character which will be simple in construction and in which the carrier is positively returned from its dumping to its receiving` position by means operated by the binding mechanism of the machine to which the carrier is attached.

A further object is to improve the construction of the means of attachment of the f fingers of the carrier to the supporting frame thereof, to insure a complete discharge of the bundles from the carrier and to enable the fingers to be readily removed and replaced when necessary.

A further object of the invention is to generally improve the construction and operation of carriers of this type in the particulars hereinafter more fully described and set forth in the claims.

In the accompanying drawings, consisting of three sheets: Figure l is a perspective view of a bundle carrier embodying my invention, showing the parts of the grain binder to which the same is attached. 2 is a perspective view, on an enlarged scale, of the ratchet pawl and its supporting arm. Fig. 3 is a similar view of an extension piece for the pawl-supporting arm. Fig. 4 is a plan view, on an enlarged scale, of the carrier, showing the same in its discharging position. Fig. 5 is a perspective view of the hinge and swivel blocks for one of the lingers of the carrier. Fig. 6 is a fragmentary plan view of a portion -of the carrier in its receiving position. Fig. 7 is a fragmentary sectional elevation of the carrier, showing one of the supporting brackets for the fingers of the carrier. Fig. 8 is a cross section of the same, taken on line 8 8, Fig. 4. Fig. 9 is a fragmentary longitudinal sectional elevation of the locking means for the carrier, taken in line 9-9, Fig. il. Fig. 10 is a side elevation of the carrier showing the same in its discharging position. Fig. 11 is a side elevation7 on an enlarged scale, of the ratchet wheel and its associated parts.

Like letters of reference refer to like parts in the several figures.

A represents the binding deck or table of a self-binding harvester, B the knotter shaft thereof provided with a crank wheel t, and C a pitman connecting the crank wheel of the knetter shaft with a crank arm on the needle shaft D. These parts are all of well known construction.

The bundle carrier is supported from the frame of the harvester and is arranged below and slightly beyond the discharge end of the binding deck and substantially parallel therewith.

E represents the frame of the carrier which is suspended from the frame of the harvester by suitable arms e, and preferably consists of a metal pipe having its forward end bent inwardly and rearwardly to form a loop, the arm c of which is connected at its end with the main part of the frame by a cross bar e2.

F represents the fingers or tines of the carrier which, in the extended or receiving position thereof, project outwardly from the machine in a substantially horizontal direction and are adapted to receive and hold the bundles as they are discharged from the binding deck. In the construction shown, five carrier fingers are employed, although a greater or less number may of course be used, as desired. ri`he lingers are separately attached to the carrier frame by universal joints or connections which enable them to swing rearwardly and downwardly to dump the bundles, the construction being preferably as follows:

Each Enger is supported by a bracket G and accordingly there are as many brackets as there are fingers. rlhese brackets are secured to the frame E at suitable distances apart and extend at an inclination above and below the frame, each being provided at its lower end with a perforated lug or swivel socket g and at its upper end with an outwardly and rearwardly extending hook g.

H represents a swivel block, see Fig. 5, which is provided with an upwardly-projecting swivel pin h which is secured and adapted to turn horizontally in the swivel socket g. The swivel block is also provided with a downwardly-projecting hinge lug h which is secured by a horizontal hinge pin h2 in a vertical slot in one end of a hinge block 1 to which the fingers F are detachably secured. By these connections, the fingers F, when free to move, can swing horizontally and also downwardly. The swivel pins h for the carrier fingers are preferably inclined somewhat toward the rear of the carrier, as shown in Fig. 7, whereby the weight of the bundles on the fingers tendsv to cause the fingers to swing rearwardly or in the proper direction to discharge the bundles.

The carrier fingers are preferably detachably secured to the hinge blocks I, so that when bent or broken, they can be removed from the carrier and replaced, for which purpose each hinge block 1 is provided on one side thereof with laterally eX- tending hooks c' i', and the finger is bent to form a loop t2 near its inner end which fits over and pivots on the hook i, while the inner end of the finger beyond the loopengages under and is held from upward movement by the hook i. The finger cannot slip laterally off of the hooks i. 'i' and the weight of the finger serves to hold its inner end in constant engagement with the hook i. The finger can be readily removed by raising the outer end of the same to free its inner end from engagement with the hook i and then slipping the loop i2 off the hook i.

The carrier fingers F are held suspended from the brackets G by chains K which are attached at their upper ends to the hooks g on the upper ends of the brackets G, and have rings at their lower ends which are slipped over the fingers and engage and support the same adjacent to the hinge blocks As the supporting hook g for each chain is located inwardly and rearwardly from the point of attachment of the chain to the finger F, the chain permits the carrier finger, when released, to move downwardly and rearwardly, in an arc of which the chainsupporting hook is the center, to the discharging position shown in Figs. l and 10.

The means just described for detachably securin the hngers and connecting them to the ame, so that they can swing downwardly and rearwardly, are desirable, but other means for these purposes could be used.

To regulate the movement of the fingers and to hold the same normally in their eX- tended receiving position, the following means are employed: Each of the swivel blocks H is provided with an inwardly-extending arm Z which is attached at its end to a link L which connects all of the swivel blocks together so that they may be moved in unison. A chain M is secured at one end to an extension of the arm l of one of the swivel blocks and passes around a pulley m journaled in suitable bearings on thek end of the frame E, and is connected at its other end to a rod N which is slidaoly supported in suitable brackets n on the frame of the carrier. This rod is provided at its forward end with a hook a adapted in one position of the rod to engage a spring catch O, Figs. 4, 8 and 9, pivotally secured on the cross-bar e2 of the carrier frame. An inclined support O is located on the cross-bar e2 below this catch and serves to support the forward endv of the rod N and hold the same normally in engagement with the catch. When the sliding rod N is in engagement with this catch, through its connection with the link L it holds the swivel block H from turning, and the fingers of the carrier are thus locked in their extended receiving position, as shown in Fig. 1. When the rod is released, the swivel blocks can turn and the fingers are free to swing rearwardly and downwardly to the discharging position shown in Figs. 4 and 10. For automatically releasing this rod for dumping the carrier, the following means are employed:

A ratchet wheelv P, j ournaled in a standard p on the frame E of the carrier, is provided with a projecting stud 7o adapted to engage a trip arm p2 onthe spring catch O to release the rod N. This ratchet wheel is turned intermittently by suitable means connected with the binding mechanism so that the wheel will be turned a predetermined distance for each bundle that is bound and de livered to the carrier. The means shown for this purpose are constructed as follows: A pawl lever p3 pivoted to oscillate on the shaft of the ratchet wheel, is provided with a spring-pressed pawl p4 for engaging the teeth of the ratchet wheel. An extension piece p5 is adj ustably secured to the pawl lever anda rod ps'connects the extension piece 705 with one arm 7' of a bellecrank lever R which is suitably pivoted on a standard r on the loop arm e on the frame E. The lever arm r is suitably connected by a link or rod r2 with the crank wheel b of the knotter shaft B, or other suitable member of the binding mechanism whereby the lever R will be reciprocated once for every revolution of the knetter shaft and will communicate this movement in turn by the rod p to the pawl lever p3. Each downward movement of the pawl lever p3 causes a definite movement of the ratchet wheel, depending upon the length of movement of the pawl lever. A suitable dog S pivoted to the standard p above the ratchet wheel engages the teeth of the ratchet wheel to hold the same from turning backwardly. It will thus be seen that with each revolution of the knotter shaft the pawl lever p3 is reciprocated and the ratchet wheel advanced a certain distance. By adjusting the eXtension piece 'p5 of the pawl lever on the latter toward or from the aXis of the ratchet wheel, the connection of the rod p6 with the pawl lever is correspondingly changed so as to increase or decrease the stroke of the pawl lever and pawl and thus turn the ratchet wheel a shorter or longer distance, as desired. As the knetter shaft makes one revolution for each bundle that passes over the binding deck, the ratchet wheel is moved a certain distance each time a bundle is delivered to the carrier. By regulating the stroke of the pawl and the number of teeth on the ratchet wheel, it is possible to regulate the movement of the ratchet wheel so that it will make one complete revolution for a certain predetermined number of bundles. In the construction shown, the ratchet wheel is provided with twenty teeth and the movement of the pawl is such that this wheel is rotated a distance of four teeth for each revolution of the knotter shaft. The ratchet wheel will thus make one complete revolution for every five bundles delivered to the carrier. Four of these bundles will therefore be received and held by the carrier and the fifth bundle will pass from the binding deck onto the carrier at the same time that the ratchet wheel completes one revolution and trips the catch O to release the fingers of the carrier, and will thus be dumped with the other four bundles. When the catch O is released, the weight of the bundles upon the carrier will cause the same to dump automatically. It some times happens that the operator may desire to dump the carrier for some reason before the entire number of bundles has been deposited thereon. For this purpose a suitable dumping lever s is secured to the catch O and is connected by suitable means (not shown) to an operating lever adjacent to the drivers seat so that the driver may at any time release this catch to dump the carrier.

The carrier is positively returned to its elevated or receiving position after being dumped by the following preferred means: Secured to the sliding rod N adjacent to its hooked end n is an upright arm t having a sliding bearing therein for a return rod T, provided with a hooked end t which is adapted to engage the arm t. The other or front end of this return rod is pivotally secured to the lower arm of the bell-crank lever R and. the rod is thus reciprocated back and forth with the movements of this lever. When the sliding rod N is in engagement with the catch O, the return rod T slides idly back and forth in its bearing on the supporting arm t and does not affect the position of the rod N. I/Vhen, however, the catch O is released to dump the carrier, the movement of the carrier fingers in dumping causes the sliding rod N to move rearwardly to the position shown in Fig. l0. In this position the arm t on this rod N comes into engagement with the hooked end lof the return rod T, and as the return rod is moved forwardly by the action of the bell-crank lever R, the sliding rod N is drawn forwardly in like manner until it engages the catch O. This movement of the sliding rod serves to return the fingers of the carrier to their eX- tended receiving position. A positive return of the carrier from its dumping to its receiving position is thus secured which is effected by the same mechanism on the harvester which operates the ,automatic release therefor, so that the return movement will be at all times regular and certain. When the carrier is being dumped, the fingers swing downwardly and rearwardly until they extend adjacent to the ground and substantially parallel with the direction of movement of the harvester, and their outer ends fold together, as shown in Figs. 4 and 10. This insures an effectual discharge of the bundles from the carrier and enables the fingers of the carrier to be completely withdrawn from engagement with the bundles before their return movement is begun.

By inclining the connecting swivels for the 'lingers rearwardly, the fingers of the carrier, when released, always tend to swing downwardly and rearwardly, while if the swivels were substantially vertical, the movement of the fingers might be hindered when the frame of the carrier was inclined forwardly, as when the machine was being used on the side of a hill.
