GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 345,546, dated July 13, 1886.

Application filed March 13, 1884. Serial No. 124,018. (No model.) I

To aZZiwhom it may concern.-

Be it known that I, JAMES It. SEVERANOE, of Fremont, in the county of Sandusky and State of Ohio, have invented certain new and useful Improvements in Grain -Binders, of which the following is a specification.

My invention relates to improvements ap plicable to grain binding machines of the class usually designated "platform-binders.

My object chiefly is to provide siniple and efficient means for completely separating the respective gavels of grain successively accumulated for binding from other grain carried by the machine, so that the connection or tangling of one bundle with another by straggling stalks of grain will be rendered impossible.

Asuitable application of my improvements, which are hereinafter particularly claimed, is represented by the accompanying drawings. The drawings show only those features of appropriate mechanism an illustration of which is needed to convey a proper understanding of my improvements. Some of these improvements may, however, be used without the others, and also be employed in connection with mechanism differing in various respects from that shown and hereinafter in detail described.

Figure 1 is a plan view with some parts omitted and others broken away. Fig. 2 is a view partly in front elevation and partly in section on the line 2 2 of Fig. 1. Fig. 3 is a view partlyin side elevation and partlyin section on the line 3 3 of Fig. 1. Fig. 4 is a view partly in front elevation and partly in section on the line 4 4 of Fig. 1, showing the gavel-separating mechanismin its inoperative position; and Figs. 5 and 6 are similar views, the section on the line 45, Fig. 1, and with the mechanism represented in positions assumed at different stages in the operation. Fig. 7 is a view partly in plan and partly in section on the line 7 7 of Fig. 8; and Fig. 8, aview partly in front elevation and partly in section on the line 8 8 of Fig. 7, showing the packing mechanism. Fig. 9 is a plan view showing details of portions of the mechanism for actuating the binding mechanism; Fig. 10, a view partly in elevation and partly in section on the line 10 10 of Fig. 9, and Fig. 11 aview partlyin elevation and partly in section on the line 11 11 of Fig. 9.

My improvements are in this instance shown asorganized so asto be especially adapted for use in connection with sundry other improvements invented by me, in some respects features shown in connection with my present improvements being precisely the same, and in other respects substantially the same,as improvements set forth in United States Letters Patent N 0. 237,135, of February 1, 1881; No. 277,356, of May 8, 1883; No. 281,570, of July 17, 1883; No. 283,671, of August 21, 1883, and No. 297,723, of April 29, 1884.

A driving and supporting wheel (not shown) is properly mounted by its axle in obvious way between the bars A A of a suitable main frame, the other chief portions of which, as shown, are the bars A B, B, and B A metallic frame, A hereinafter designated the binder-frame, is suitably secured to the main frame and supports the binding mechanism.

Mechanism for delivering the cut grain to the inner end of the platform 0 consists, as shown, of an endless carrier composed of sections a, consisting of a series of belts with teeth a, working, as moved inward, through the platform-slots b, and returning or moving outward beneath the platform, as fully set forth in my above mentioned Patent No. 297,723.

A series of short slots, b, for a purpose further on to be explained, are made in the surface of the platform at or near its inner end and adjacent to a grain passage-way or throat, 0, leading from the platform to a grain-receptacle, D, which, as well as the grain passage-way, its curved spring-arm d, and bent spring-fingers d, and a series of feeding and packing teeth, E, are the same as in my Patent No. 281,570, of July 17, 1883. The slots 1), it should be noticed, with the exception of the rearmost one, are arranged between the slots 1) for the carrier-sections a.

Instead of the several series of packing-teeth being actuated from the packer-shaft E by planetary gearing in all respects such as before employed by me, I in this instance actuate the teeth by an arrangement of gearing as follows: The central fixed pinion, '6, fast on v the bearing-sleeve for one end of the rotating packer-shaft, engages the larger idle-gears F, (one of these gears for each of the series of teeth,) which are of such size that each revolution of the packer-shaft will impart a halfrevolution to the idle-gears. Each idle-gear is formed with a pinion,f, corresponding in size both with the fixed central pinion and with driven pinions e on the rotating driven shafts F of the respective series of packerteeth. The idle-pinionsf mesh with the driven pinions. The driven shafts F and the stud-shafts f of the idle-gears and their attached pinions are supported by the spiders E" E, which are secured to the packer-shaft. It will be seen that while the packer-teeth, which are fixed to their shafts, act alternately with their opposite ends to force the grain along the passage-way to the receptacle, and gradually withdraw from the accumulated grain, as before, yet by my present improvements I attain greater compactness of gearing, bring the shafts of the teeth closer to their casing F, and am enabled to reduce the area of the casing, and thus economize space,without lessening t-helength of the acting portions of the packer-tecththose portions which project beyond their casing and act upon the grain. Obviously the packer-teeth must be made of a length such that they do not proj eet from their shafts a distance exceeding that between these shafts and the packer-shaft proper. The length of the teeth being limited, it becomes important to have their shafts move as close as practicable to the concentric portion of their casing, so that the teeth may act properly upon the grain in the passage-way. Besides, the closer the shafts of the teeth pass to the casing the shorter the teeth may be made while projecting into the grain to agiven extent, and so the strain upon the parts resulting from the employment of long teeth be lessened.

It will be seen that the advantages arising from the above-described construction of packing mechanism result from having the driven pinions c of the same size as the fixed central pinion, instead of twice its size, as before, and causing the large idle-gears for lessening the speed of the driven pinions relatively to that of the packer-shaft to lap the driven pinions and connect with them through or by way of the idle-pinions, instead of engaging them directly. In this way the distance between the packer-shaft and the driven shafts is lessened to an extent corresponding with the amount of lap of the driven pinions by the idle-gears, while the packer-teeth are correspondingly shortened and the concentric portion of the casing brought correspondingly nearer the packer-shaft.

Tripping mechanism automatically operated by the pressure of the grain to throw the binding mechanism (a binder-arm, suitable knotter, Ste.) and the gavel separating mechanism into action, as in turn to be explained, as in this instance provided, is as follows: A tripping-lever, G, overhangs the grainreceptacle D, so as to be rocked upward to a suitable extent by the pressure of the grain when accumulated in the receptacle in quantity sufficient to form a gavel. This trip ping-lever is fast at its heel end to a rockshaft, G, turning in suitable bearings attached to a cross-piece, G constituting the top of the frame of the packer-casing. As shown, the tripping-lever and its rock-shaft are made of a single rod bentinto shape. At its front end the rock-shaft is provided with a crank-arm, g, which projects downwardly, and engages by means of a wrist or pin, g, at its lower end with a slot in an upwardly projecting and laterally-curved crank, g", secured to the rear end of asecond and doublycranked rock-shaft, II, the other crank, 71, of which is at its front end and projects downwardly. The crank h, like the slotted crank, projectslaterally toward the grain-receptacle. The doubly-cranked shaftis supported so as to rock in bearing-brackets H h on the framebar B. The doubly-cranked rock-shaft H of the tripping mechanism is connected by means of its front crank and a link-rod, h, with suitable clutch mechanism, such as in detail to be described further on, by the actuation of which intermittinglyacting gearing for operating the binding mechanism and the gavel-separating mechanism is thrown into and out of action, the clutch mechanism serving to throw a main actuating driven shaft, I, into and out of gear with a gear-wheel, J, hereinafter termed the primary gear, as through or by way of connections with it the binding mechanism and gavel separating mechanism are actuated. The main actuating-shaft I is continuously rotated during the operation of the machine by means of a bevelpinion, 1, fast upon it, and a corresponding gear, 1", fast on a shortdriving-shaft, J,mounted in a sleeve-bearing, J", of the binder-frame, and driven by means of suitable gearing connecting it with the driving-wheel in obvious way. The main actuating-shaft extends from front to rear of the machine, and is mounted in suitable bearings, iiii' of the binder-frame. At its rear end this shaft is provided with a sprocket-pulley. A chain passing around this pulley and around a pulley on the rear end of the packer-shaft E serves to operate the packing mechanism. A counter shaft, K, supported in suitable bearings of the binderframe, is actuated by means of a pinion,7c, fastened to it, and a gear, K, fast on the main actuating-shaft and engaging this pinion. A crank -wheel, K provided with the usual wrist-pin, 7c, is secured to the forward end of the counter-shaft, and serves by means of a pitman to actuate the cutters, as will readily be understood. A sprocket-pulley, Z, on the counter-shaft K and its chain serve to impart motion to a eonsiderabl y larger sprocket-put ley, L, on a shaft, Z, for actuating the belts of the endless carrier. This carrier-actuating shaft 1 connects with and imparts motion to the driving-pulleys L of the carrier-belts by means of bevel-gearing in obvious way. One only of the belt driving-pulleys is shown, (see IIO Fig. 2,) and the bevel-gearing connecting 1 sections ofthe clutch, so that when the stud them with their actuating-shaft is not shown.

These omitted parts are fully represented in my before-mentioned Patent No. 297,723.

As shown, the clutch mechanism for throwing the main actuating-shaft I into and out of gear with the primary gear J is in general features of construction, similar to that shown in my before-mentioned Patent No. 237,135; but in various details the mechanism now to be described is different. The link-rod h is connected to the upturned outer end of a horizontally-vibrating clutch-controller, M, composed of a rod forked at its inner or heel end to pass above and below the front cross-piece of the binder-frame A to which it is secured by a pivot-bolt, m, and having a stud, m, near its outer end close to where it is bent upward, the stud projecting toward the sliding section N of a clutch-coupling on the main actuatingshaft. That member of the fork of the clutchcontroller which passes beneath the binder. frame is extended and bent inward to constitute a heel-lever, M, to which one end of a coiled spring, M", is secured. The other end of the spring is connected to a pivoted lever, 0, outside of but near its pivot. This lever serves to dog and release the clutch-controller, as soon to be explained, and it is pivotally supported by an arm, 0, secured to the binder-frame, has a short inwardly-projecting arm or heel, 0, and a shoulder, 0, near its outer end, to engage with and dog the clutch controller when by the action of the link if the controller is pulled outward or against the force of the spring M Which acts also with a tendency to keep the lever and upturned end of the con-' troller always in contact, as will readily be understood. The sliding clutch-section N is connected with the main actuating-shaft in well-known way, so as to rotate constantly with it, and is acted upon by a spring, N, which presses inwardly upon it, or with a tendency to move ittoward the non-sliding section N of the clutch, which is formed with a pinion, a. This pinion-section of the clutch is loose on the main actuating-shaft, and the pinion engages the primary gear. The heads or adjacent surfaces of the clutch-sections are formed so asto interlock, as usual, when brought together. The sliding clutch-section is enlarged at its outer end, being formed with an annular shoulder or collar, N between which and its head there is an annular groove, a, of a size such as to receive the stud m of the clutchcontroller. Inclined recesses or cam-grooves n are formed in the periphery of the clutchcollar, corresponding in number with the spurs projecting from the head of the sliding clutchsection-two in this instance. Each camgroove at one end extends nearly across the periphery of the collar, and is gradually narrowed from its wide end to a point at its opposite end. Throughout its length each groove extends entirely through to the inner surface of the collar, and its depth is less than that of the annular groove between the two of the clutch controller is in this annular groove there can be no endwise movement of the sliding clutch-section. The wide end of the one cam-groove is adjacent to the point of the other, so that the two grooves extend near- 1y or entirely around the clutch-collar. The primary gear is provided with awiper-can1,j,to

r act upon the heel 0 of the lever O, and is fast on an intermittingly-actuated shaft, P, which makes one revolution at each actuation, and is connected with the binder-arm and the gavel-separating mechanism by means such as further on to be explained,

From the above description of the clutchtripping mechanism and the clutch mechan' ism it will be seen that when by the pressure of the grain accumulated in the receptacle the tripping-lever is thrown into action the operation will he as follows: 'The crank of the rockshaft G acts by its pin first in the short vertical or straight portion of the slot of the crank of the second and doubly-cranked rockshaft H, and after having imparted sufficient movement to this rock-shaft to cause it, by way of its crank hand the link If, to draw the stud of the clutch-controller M out of the groove between the clutchsections and outside of the path of travel of the sliding clutch-section, then the crank-pin may move in the curved portion of the slot in the crank 9 without imparting further movement to the doubly-cranked rock-shaft, because of the fact that the movement at first imparted to this rock-shaft was such as to bring its properlycurved slot into a position concentric with the axis of the rock-shaft G. As the trip ping-lever is moved upward after having per formed its function, when the binder-arm is acting on the grain in the receptacle, as further on will appear, the importance of guarding against any additional movement being thus imparted to the doubly-cranked rockshaftis obvious. The withdrawal of the stud of the clutch-controller from the annular groove in the sliding clutch-section and the dogging of the controller by the shoulder o of the lever 0 leave this section free to be engaged by the action of its spring with the pinion-section of the clutch, and the rotation of the pinion with the main actuating-shaft imparts motion to the primary gear and its shaft. Shortly before the completion of its single revolution the primary gear acts by its wipercam against the heel 0 of the lever O and moves it so as to release the controller, which is acted upon by its spring to move the stud m inward against the clutch-collar. The stud now enters one of the cam-grooves in the collar, first engaging its wide end, and forces back the sliding clutchsection against its spring, disengaging the clu'tchsections at about the time the stud passes from the point of the cam-groove into the annular groove, as will readily be understood. After each actuation the primary gear, the tripping-lever, and the roclcshafts come to rest in the positions in which they are rcpresented in the drawings, preparatory to re peating the above-described operation. A rocking binder-arm, Q, is fastened to the inner end of a rock-shaft, (j, mounted in a sleevebearing, Q, formed with or rigidly connected to the upper end of a rocking post, Q. At its outer end the binder-armrock-shaft has a segment-gear, q, keyed to it,and this gear engages an idle-pinion, qi'which is supported by a studshaft of the rocking post (9,", and engages a segment-gear, Qfiwhich is loosely mounted on a shaft, q, to which is fastened the rocking post which supports the binder-arm roclcsliaft. The intermittingly-actuated shaft 1 is doubly cranked, its cranks p p projecting from it at or about a quadrant apart, or at a right angle to each other. A pitman, 1-, connects the crank p with the rocking post, and a pitman, P, connects the other crank, p, with the segment-gear Q. By these means the binderarm is operated at each actuation of the shaft 1?, as fully set forth in my Patent No. 237,135, and, as will readily be understood from inspection of said patent, the binder-arm, by reason of the two motions imparted to itthe one about its own axis, or independently of the movements of its supporting-post, and the other with the post-is caused to reach out far enough to embrace the grain in the receptacle D,where the gavels are accumulated, and then draw it inward past the free end of the tripping-lever to a suitable binding receptacle above proper knotting mechanism. The binding-receptacle in this instance is constituted by the upper surface of the knotter-casing 1*,which is provided with a depression for the bundle to rest in, and a casing (not shown) for the binder shafting and gearing, which extends to or nearly to the rear of the binderframe from a point about over the drivingshaft J, as will readily be understood.

In order to effect a thorough separation of the grain forming one gavel from that for air other without loss of time or to the slightest extent encroaching upon the time allowed for the operation of the binding mechanism in securing the respective bundles, I provide intermittingly-operated gavel-separating mechanism acting upon the grain on the platform in opposition to the action upon it of the mechanism by which it is delivered to the passage-way and within reach of the packing mechanism, the gavel-separating mechanism serving not only to arrest the movement of the grain inward by the endless carrier, but also to move the grain subjected to its action outward or away from the packing 1necl1anism, thus quickly providing a sufficient space between the grain inside of the separating mechanism and that outside of it, to insure complete isolation of the grain about to be bound from other grain.

As in this instance shown,the gavel-scparating mechanism and the connecting mechanism by which it is operated from the intermittingly-actuatcd shaft Pare as follows: A shaft, S, is provided with a series of rigidly-attached separating-teeth, 8, arranged in a row extending crosswise of the platform, above which the shaft is adj ustably supported, so that the teeth may be caused to enter and leave the platformslots b and be moved outward therein against the incoming grain. The toothed shaft is of a length less than the width of the platform, and is adjustably supported at its ends by being mounted in guideway-brackets T T, so that it may rock vertically and move to and fro horizontally, the ends of the shaft projecting into guide-slots t i of these brackets, which are secured beneath the bar B of the main frame. The toothed shaft has a short crank, s, at its rear end, and the slot 1/, in which this cranked end works, is angular, the main or horizontal portion of the slot terminating at its inner end in a shorter vertical portion. The slot t in thebracket T may also be of angular form, and the front end of the shaft be cranked,if preferred; but the desired to-and-fro and vertical movements may readily be imparted to the toothed shaft with the parts constructed as shown. A springis caused to act upon the toothed shaft of the gave1-separating mechanism to restore it to its inoperative position after it has been operated by positively-actuated mechanism. A rod,U,sliding in suitably-supported brackets a u,is connected with the toothed shaft by eyes 0 1), through which the shaft passes. One of these eyes is formed in the sliding rod,and the other at the outer end of an arm, V, projecting inwardly therefrom. Aspring, U,coiled about the sliding rod, bears at one end against the enter one of the brackets to, and at its other end against the arm V. A rod, V, forming part of the mechanism connecting the gavelseparatingmechanism with the shaft 1, has jointed connection at its opposite ends, respectively, with the sliding rod of the gavelseparating mechanism, anda crank, in, at the rear end of a rockshaftflV, of the connecting mechanism. This rock-shaft is mounted in suitable bearing-brackets,shown as secured to the bar A of the main frame, and has another crank, \V, near its front end, which is provided with a slightly-projecting elongated side lug, w, to be acted upon by a segment-wiper, Y,fast on the intermittinglyactuated shaft 1, against or close to which shaft the outer end of the crank \V rests when the gavel-separating mechanism is not in action.

From the above description it will be seen that at each actuation of the binder-arm, and as the mechanism is in this instance adjusted just after the binder-arm begins its movement, the gavel-separating mechanism is thrown into action, the operation being as follows: The wiper Y acts against the side ing of the crank \V, and by the motion thus imparted to the rock-shaft \V the sliding rod U is moved outward against the force of its spring,the toothed shaft being rocked during the first part of this movement,owing to the control exercised over it by its crank when being drawn down the vertical portion of its guide-slot,and the points IIO of the separating-teeth are thus caused to] enter their platform-slots at or close to the mouth or entrance to the grain passage-way. By the continued action of the wiper the separating-teeth are then forced outward as their shaft is moved along its guide-slots, and the crank on the shaft, working in the horizontal portion of its guide-slot, prevents the teeth from being turned back by the pressure of the grain being moved outward by them against the action of the endless carrier. As that portion of the grain about to be bound, which is acted upon by the packing mechanism and carried along the passage-way while the separating-teeth are in action, is being moved one way at the same time the grain in the platform is being movedthe other way, it will be seen that a very quick separation results, and that by the time the wiper ceases to act on the crank there will be a considerable space unoccupied by grain extending from the separating-teeth to the grain-receptacle. Then the wiper releases the crank, which, as the mechanism is in this instance timed, is when the binder-arm is well advanced on its inward movement and nearing the end of its actuation, the toothed shaft is actuated by the spring U and the gavel. separating mechanism is returned to its position of rest, as will readily be understood, the above-described operation being repeated at each revolution of the intermittingly-actuated shaft carrying the wiper. The endless carrier being left free to act by the backward horizontal and rocking movements of the separating-teeth, the delivery of grain to the passage-way and packing mechanism is resumed.

I do not wish to be understood as confining my invention herein claimed to the details of construction and precise arrangements of parts described and illustrated, as my improvements may be modified in various respects without departure from my invention.
