GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 354,251, dated December 14, 1886.

Application filed July 13, 1885.

Serial No. 171,517. (No model.)

To all whom it 17mg concern.-

Be it known that I, JOHN F. SEIBERLING, of Akron, county of Summit, and State of Ohio, have invented a new and useful Improvement in Grain-Binders, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

My invention relates to a novel construction and arrangement of the parts of the knotting mechanism, with a'view, mainly, to securing greater compactness of the parts and a reduc- 11011 in the weight of the said mechanism as compared with constructions now in use. It will be understood from the following description, taken in connection with the claims.

In the accompanying drawings, Figure 1 is an outer side elevation of my improved k notting mechanism; Fig. 2, an end elevation of the same. Fig. 3 is aplan view of the same, with the cam-wheel shown in section; Fig. 4,, a face view of the cam-wheel detached; Fig. 5, an end elevation, looking from the end adjacent to the canrwheel, with said wheel removed; Fig. 6, aperspective view of the cordholder-carryin g arm and parts connected therewith; Fig. 7, a similar View of the knotter, the end ofthe jointed shaft to which it is attached, and of the pivoted frame supporting said end, with the knife attached; and Fig. 8, a side view of the parts shown in Fig. 7.

A represents the knotteractuating and camwheel shaft-5 A, the cam-wheel secured to and rotating with said shaft.

C is a knotter-mechanism-supporting frame or casting, provided near its upper end with a sleeve, C, surrounding the shaft A, and at its lower end with afoot-flange, 0 through which, in practice, it is bolted to the knotter-shield or breast-plate, the shaft A serving to uphold the casting 0 and the end of the breast-plate connected therewith, while the latter prevents said frame or casting from turning with or upon the shaft A, in a manner well understood. The frame or casting G is provided with arms 0 and 0, extending obliquely upward and outward, forming supports for the rock-shaft or pivot on which the cord-holdercarrying arm D is suspended, and at c with a slightly-inclined upright sleeve -bearing for the upper portion of the inclined and jointed knotter-shaft B, which is arranged at one side of the sleeve 0 of the knotter-mechanism frame, crossing the horizontal plane of .the shaft A, as will be explained. Thelower pivoted portion, B, of the knotter-shaft has the knotter -hook B secured to it, and is journaled in a frame, E, pivoted by means of a rock-shaft or pivot, E, formed upon it, in a transverse sleeve, 0*, formed in the frame 0, so arranged that when the knotter-shaft is in position to be flexed th'e jointb therein will be in line with said pivot E. By this arrangement of the knotter-shaft to cross the plane of its actuating-shaft upon one side it is made to assume a position substantially tangential to the latter, or to the sleeve 0, in which it rotates, and to accommodate this arrangement the teeth of the segment a on the camwheel A have a corresponding tangential or spiral arrangement given to them, (shown in Fig. 4,) instead of the radial arrangement usually employed, and by setting the shaft to incline rearward or outward and away from the adjacentpperative face of the canrdisk from its upper end, to which the actuating-pinion B" is attached, downward, its lower end, to which the knotter is attached, is sufficiently removed from the cam-Wheel A to permit the needle, the end of which is indicated at F, to pass between said shaft and the wheel, as shown in Fig. 1. The needle in practice is secured to and operated by means of a rockshaft geared to and having its movements timed to those of the shaft actuating the knotter mechanism, and is arranged preferably 'to operate from beneath the binder-table, in a manner well known.

The frame or arm D, carrying the cordholding devices, is shown in Fig. 6. It is provided at its upper end with a fork, the arms ddof which terminate in eyes or short sleeves, which suspend it from a rock'shaft, D, supported in the arms 0 and 0 of the frame 0, the

fork striding a tubular rock-shaft, D'", mounted and turning on the same pivotal center or rock-shaft 1). The forward arm, (1, of the fork has a laterally-projecting fork or arms, (I (2, formed on its side adjacent to the shaft A, said fork striding the latter and a cam projection, a, on the hub of the ca1n-wheel, the latter servingby its action on said arms at d to impart a lateral vibration to the arm D in each revolution of the shaft Aand cam-wheel A, for yielding cord to the knotter, in a manner well understood.

The cord-holding disk G is mounted upon a stud-pivot, g, secured to the lower end of the vibrating arm D, and upon this same pivot, between the disk G and the arm D, is pivoted an arm or lever, 9, adapted to swing on said pivot, and provided near its swinging end with apin, g", to which the lower end of a connecting rod or pitman, H, is attached, the upper end of said rod being connected with a wrist-pin, i, on a crank-arm, D keyed or otherwise secured to the rock-shaft D. The forward end of shaft D has a crank arm, D", formed upon it, provided at its outer end with a wrist-pin havingafriction-roller, i, mounted upon it, which runs in the cam-groove A in wheel A, and which serves at each revolution to Vibrate the rock-shaft D, and thereby to impart a vertical vibration to the lever g. The lever extends beyond the pin 9', and has a pawl, 9 pivoted to its outer face, adapted to engage notches in the cord-holder disk G, for imparting an intermittent rotary movement thereto, and adapting it to carry the cord into the cord-holding shoe G, in a manner well understood. The pawl g is held in engagement with the notched disk ordinarily by its own gravity, which permits it to back freely over the face of the disk when the arm g is depressed for moving the pawl into position to again act on the disk; but to insure its engagement with the latter it is provided on its upper face with a spur, g, which projects laterally over the end of lever g, and which, when thelatter is depressed, comes in contact with a spring, H, secured to the rod H, and which serves to force the pawl into engagement with the disk for actuating the latter. The spring H at its lower free end overhangs the end of the lever g, and as it rises with the rod H, after having forced the pawl into engagement with the disk, it passes off the spur g, and rests on said end of lever g, leaving the pawl freeto risein backing over the notched periphery of the disk held down by gravity only, as explained.

The shoe G consists of a pendent curved bar or plate pivoted at its upper end to a laterally-projecting lug or ear, j, on the frame or arm D, near the upper end of the latter, and provided at its lower end with a groove or parallel ribs, in or between which the edge of the cord-holding disk G moves for engaging and holding the cord. The shoe G is provided at its lower end on its side or edge with a laterally-projecting spur, against which thelower free end of a spring, H bears for holding the shoe up against the action of the diskGwith-the desired pressure. This spring is secured, by means of a set-screw or adjusting-bolt, to the forward face of a laterallyprojecting lug or ear, j, formed on the arm D,

below and slightly in rear of the lug j, as

- shown. The upper end of this spring H is curved slightly inward toward its supportinglug at h in such manner as to rest upon and hold the body of the spring away from the face of the lug, thereby permitting the adjustment of the set-screw, and the consequent tension or pressure of the spring on the spur g, asdesired.

The tubular rock shaft or sleeve D is mounted on the rock-shaft D, between the arms D and D thereofland between the arms d d of the cord-holder arm D, as explained, and has on its forward end a curved arm or hood which overhangs the arm (I, and is provided with a crank-arm, D having a forwardly projecting pin carrying a frictionroller, '5 which projects within the camgroove A and causes a vibratory movement of the arm D and sleeve D? at each revolution of the cam-wheel. The sleeve D surrounds the rockshaft D, and is supported thereby and by the forward arm, 0, of the frame (7, said arm having an enlarged bearing, provided with a removable halfbox, 0 (see View of said halfbox detached in Fig. 5,) facilitating the removal and replacement of the sleeve D and shaft D. The rear end of the sleeve D has a crank-arm, D, formed upon it, provided with a rearwardlyprejecting pin, d, from which a connecting-rod, k, extends downward to a perforated lug or ear, 0, 011 the rear face of the pivoted arm E, on which the lower pivoted end of the knotter-shaft is journaled. The joint in'the knotter-sha t B B isin line with the pivot E, on which the arm E is supported, and as thelatter is vibrated or swung back on said pivot by the action of the camwheel on the sleeve D and the connections of the latter therewitlnthe knotter will be carried with it for withdrawing its point from the loop formed in the knot, and thereby freeing the bundle. The arm or frame E has the knife 0 for severing the cord, secured to and moving with it, and arranged to sever the cord, and thereby to free the bundle as the arm swings backward to withdraw the knotterpoint from the loop. The arm or frameEhas a cam projection, 6", formed on its lower face, which, in the rotation of the knotter-shaft to form the loop on the knotter, serves to open the jaws of the knotter to receive the ends of the band, said cam acting on a roller, Z, on a.

heel projection of the movable jaw of the knotter for that purpose. An arm, E on the swinging arm or frame Ehas a' pendent spring,

L, secured to it, which extends down in rear of the knotter B and acts upon a roller, Z, mounted on a heel-extension of the moving jaw thereof for holding the latter snugly against the fixed jaw while the knotter is being vibrated to free it from the loop. The pinion B" on the knotter-shaft has the usual delay surface, B, formed upon it, which operates, in connection with the rear face, a, on' the cam-wheel to hold the knottershaft against rotation, except when acted on by the toothed segment a,- but the mechanism being in these and other details of construction similar to others in common use, and not being herein claimed,need not be described.

ICC

IIO

It will be apparent from the foregoing description that the arrangement of the jointed knotter-shaft, whereby it is made to cross the plane of its actuating or cam wheel shaft, and at an inclination to the face of the cam-wheel, so that while operated thereby through a pinion on one end its opposite end will be sufficiently removed from said cam-wheel to permit the free passage of the needle between,

said shaft and the face of the cam-wheel, enables me to bring the knotting mechanism into very compact shape-a very desirable feature in practice, and one constituting the main object of my present construction, as explained.

Having now described my invention, I claim as newl. The combination, with the cam-wheel, of the knotter-shaft crossing the plane of the knotter'actuating shaft and the face of said wheel, and inclined laterallyin relation to and actuated by the latter, and the needle arranged to pass between said knotter-shaft and the camwheel, substantially as described.

2. The spiral segmental gear on the camwheel, in combination with the knottershaft crossing the plane of the cam-wheel shaft and inclined laterally to the face of the cam-wheel, and having its actuating-pinion located on one side of said cam-wheel shaft and the knotter on the opposite side thereof, substantially as and for the purpose described.

3. Thecombination, with the cam-wheel and the shaft supporting and actuating it, of the knotter-shaft having its actuating-pinion on one end and the knotter-hook on the other, and arranged in close proximity to and crossing the plane of the cam-wheel shaft in laterally-inclined relation to the face of the camwheel, and the spiral segmental gear on the cam'wheel for actuating said knotter-shaft, substantially as described.

4. The jointed knotter-shaft, in combination with the vibrating hinged arm or frame E, carryingtheswinging end or part of said shaft, a cam for opening the knotter-j aw, and aknife for severing the cord, and mechanism, substantially as described, for vibrating said arm or frame, and the hinged part of theknotter-shaft journaled thereon, substantially as described.

5. The combination of the cam-wheel A, the shaft D, and tubular shaft or sleeve D mounted and turning on said shaft D, the vibrating arm or frame E, knotter B, and corddisk G, and their supporting and actuating devices, substantially as described, whereby said knotter and disk are both vibrated from the same cam.

6. The rock shaft D and rocking sleeve D,

mounted thereon, both connected with and adapted to be operated by the same cam, in combination with the cord-holder arm supported by and Vibrating on said shaft, the swinging arm carrying the knotter, and the knife for severing the cord, and mechanism, substantially as described, for actuating said cord-holder and knotter-carrying arms.

7. The combination of the cord-holding disk, its actuating-pawl y the connectingrod H, and the spring H arranged to be disengaged from said pawl when the latter is raisedin operating the disk, and to be brought into contact therewith when the pawl isdepressed, substantially as described.

8. The combination of the jointed knottershaft and the hinged arm or frame supporting the swinging end of said shaft, the joint in the shaft and the frame-pivot being arranged to coincide, substantially as described.

9. The swinging cord-holder arm or frame provided with the fork or arms d and d, and the cam on the cam-wheel shaft for actuating the same, in combination with the hinged arm of the knotter-frame carrying the hinged end of the knotter-shaft, knotter, and means, substantially as described, for vibrating said hinged arm of the knotter-frame and knotter.

In testimony whereof I have hereunto set my hand this 1st day of July, A. D. 1885.
