SYLVANUS D. LOCKE, OF HOOSIOK FALLS, NEW YORK.

HARVESTER-BINDER.

SPECIFICATION forming part of Letters Patent No. 236,898, dated January 25, 1881.

Application filed July 14, 1879.

To all whom it may concern:

Be it known that I, SYLVANUs D. LOGKE, of Hoosiek Falls, in the county of Rensselaer and State of New York, have invented a certain new and useful Improvement in Harvester- Binders; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure lis a plan view of a harvester-binder to which my improvements are applied. Fig. 2 is an end view of the same. Fig. 3 is a rear view of a portion of the machine. Figs. 4 and 5 are detail views of the cord holding, looping, tying, and cutting mechanism.

Similar letters of reference in the several figures denote the same parts.

This invention relates to that class of automatic grain-binding machines in which a cord or flexible band is applied around the gavel and secured by a knot; and it consists, first, in an improved construction of the cord-holding device which co-operates with the looper and tyer in forming the knot; and, secondly, in the combination of said improved device with the other co-operatiu g parts of the mechanism.

In the drawings, A represents the harvester, which in the form here shown contains the usual cutter a, platform a, endless-apron carrier a elevator a draft-tongue a, draft-w heels a a drivers seat a", and binding table or platform B, these several parts, with their necessary and usual accessories, being of .any approved form and construction.

Upon an offset, a, of the harvester-frame there are attached, by screws or otherwise, two castings, F, supporting traveler-rods ff. An adjustable frame, G, is mounted upon and guided by said rods, the purpose of which frame is to support the binding-platform B, the band-carrying arm, and the binding and tying mechanism, and enable them all to be adjusted with relation to the length of the grain and its position on the binding-table. This frame and its traveler-rods are not claimed herein, for the reason that they are shown and claimed in other pending applications filed by me for Letters Patentthereon. By means of a lever, H, the driver, from his seat, slides the frame back and forth upon the traveler-rods, and, as the binding-table is supported by the frame G and secured thereto, it adjusts back and forth with said frame, and thus always maintains the proper position relative to the binding mechanism. The top of the frame G is stayed by braces G G extending to a slidin g plate or block, G guided by a rail, G on the top of the harvester-frame; but said braces and guide-plate are not claimed herein, because claimed in another of my applications for Letters Patent.

0 is the main driving-wheel, which actuates the holding and tying mechanism and the ban d-carryin g arm. It is continuously rotated in the direction of the arrow by means of circumferential cogs meshing into asliding feathered pinion or trundle, K, on a shaft, K, which, in turn, is driven by any suitable connection to the main power shaft or wheel of the harvester. The sliding pinion K automatically adjusts itself on its shaft to the position of the main wheel 0 as the latter may be from time to time moved back and forth by the lever H.

The shaft D of wheel 0 passes horizontally through the lower arm of the frame G, and, projecting at the angle or corner thereof, is provided with a bevel-pinion, d. The latter meshes into a similar pinion, d, on the lower end of a vertical shaft, D, which has its bearings in the upright part of the frame. At the upper end ofthe vertical shaft is another bevelgear wheel, (1 having only a mutilated-gear rim, which drives intermittingly a bevel-gear, 01 on the end of aho'rizontal shaft, D having its bearings in the upper part of the frame. The bevelgear d is provided with a delayplate, 01", (see Fig. 1,) to hold it from rotating except when actuated by the gear -teeth on wheel 0?, and openings d are made through the wheel d to permit said delay-surface to go into and out of engagement, and to allow any dirt or dust that may lodge on the wheel d to drop through and escape, instead of clogging the wheels. At the opposite end the shaft D is provided with a crank, d", which actuates the band-carrying arm I. The latteris curved as shown, and is at its upper end, above the crank d constructed with a curved and slotted extension, 1, into or through the slot of which extends a headed bolt or pin, 73, from an upright standard or arm. g, of frame G, extending above the axis of the crank (1 A grain-separator and compressor, J, oscillating on an arm,j, and held back normally by a spring,j, against a stop,j, serves to compact the gavel and to separate the old gavel from the new one about to be formed; but as this device and the peculiar binding-arm with its operating mechanism are described and claimed in another application filed by me, they are not claimed herein.

The looping and tying mechanism is supported upon a bracket, I formed upon or affixed to an upright standard or lug, g, projecting up from the lower part of the frame G, by the side of the wheel C. Thisbracket extends over the top of the wheel and down on the opposite side thereof, as shown, and is provided with two cylindrical bearings, arranged obliquely to each other, in which are supported two small rotatory shafts, e 0, both projecting at their upperand lower ends from the said bearings. The shaft 0 carries the tying-head M at its upper end, and a gear-pinion, c, and delay-plate c at its lower end. The shaft 0 carries the holding and cutting devices at its upper end, and a gear-wheel, C2, and suitable delay-surfaces 0, two or more in number, at its lower end. The gear-wheel c is driven by a long gear-rim, c, on the side of the wheel C, and the gear-wheel c is driven by gear-teeth 0 arranged on the same side of said wheel, but preferably farther from its center, suitable recesses being provided for the delay-surfaces. The bearing of shaft 0 extends somewhat higher than that of shaft 0, so as to bring the lower end of the looping and tying head nearly on a line with the upper part of the holding device; and between the two bearin gs the bracket is recessed or concaved, as shown at e, to prevent any entanglement of the tying and holding mechanism with the grain or with the fiber from the bands, which obstructions are, by this means, allowed to drop and escape.

The cord holding and cutting devices are constructed as follows: N is a disk atiixed to the upper end of the shaft E, so as to rotate therewith, and provided with notches n, preferably three in number, the metal at the rear edge of the notches projecting in the shape of a hook, it, as shown. Beneath this disk is arranged a flat smooth metal plate or shoe, 0, secured at its outer end to the bracket, as shown at 0, and curved or hooked partially around the shaft 0 or hub of disk N. The under surface of the plate or disk N is contiguous to the smooth plate 0, and is formed with ratchet-teeth, as shown at 11 which are set forwardly or against the stress of the cord, to insure its taking a good hold on the latter. A screw, 19, serves to adjust the plate 0 more or less closely to the toothed under side of the disk. The extremity of the curve or book of plate 0 lies immediately in front of the open notch n on the side next to the path of the band-carrying arm, and is beveled inward or undercut to guide the cord inward under the toothed surface a and between said toothed surface and the upper surface of the plate 0. A cutter, S, is pivoted on the end of the shaft 6, or centrally of the disk N, and is provided with a projecting knit'eedge, s. This cutter is actuated by a spur, t, under the loopinghead, and is limited in its movements by a stop-pin, f, projecting from the bracket E, as shown.

The looping-head M is constructed in the peculiar shape shown in Figs. 4 and 5, having the enlarged or conical base and the projectin g curved and tapering jaws m m. The jaw m is rigid, but the other, m, is a stiff spring. A projection, m between the jaws serves to prevent any retraction of the cord therefrom. The rotating notched disk N and looping and tying jaws m m are timed so as to occupy the relative positions shown in Figs. 4 and 5 when the machine is ready to commence operations.

The binding-tableis provided with the usual guides B B, slot B and yoke B. At the edges of the slot, adjacent to the binding mechanism, two flanged metal plates, I) b, are secured to its edge,one of which, b, is provided with a hook-shaped notch, I), while the other is provided with a projecting flange, Ir". The needle or band-carrying arm is curved or bent, as shown at i, to enable it to run under the flange If and clear the projecting point at W, while the band, running through the end i of the arm underneath, is drawn directly in line with the hook b and its engagement therewith is assured. The two flanged plates b I; serve the further purpose of deflecting loose grain, dirt, &c., away from the slot and from the mechanism beneath, and by nearly closing the slot above the said mechanism they greatly conduce to the protection of the parts from the access of grain, straw, and other obstructions. These flanged plates 1 do not claim herein, as they are claimed in another application for patent filed by me.

The cord is supplied and kept at the proper tension by any suitable means, the particular device here shown for such purpose being a cylindrical cord-holder, R, with spring tensionarm 1', as described and claimed in another application filed by me for Letters Patent thereon.

The operation of this improved machine is as follows: The cord is first put through the end of the arm I, and its extremity is either held by the hand or is fastened to a pin or other suitable device over the band-carrying arm at or near the crank-connection. The machine is then operated, causing the arm I to descend into the slot B and sweep forward to a point opposite to the tyingmechanism, where it stops temporarily by reason of the unmeshin g of the gear-wheels d d". This movement of the arm 1 brings the cord opposite or into the exposed notch n of disk N and within reach of the curved looping-jaws m m. The tying-head then revolves, catching around over the cord, forcing it securely into the notch n, and loop- I ing it around the head. g Aboutthe time the first revolution of the .shaft 0 is completed the shaft e and its disk N begin to rotate, perform one-third of a revolution, and stop, thereby forcing the cord in under the said disk and between its roughened holding-surface and the upper side of the flat plate 0, which clamps the cord securely between said two surfaces. The movement of the mechanism as described bends the cord at an abrupt angle around the edges of the notch in the disk, and thus increases the friction upon it and contributes to prevent its being afterward accidentally drawn out of the clamp. It will now be noticed that the axis of rotation of the holding-disk is inclined to the axis of rotation of the tying or looping head, the lower edge of the disk being nearest to the head. It will also be observed that the notch, when it receives the cord, is down near the looping-head, and that, as the holding-disk rotates with the cord engaged in the holder, the cord is thereby elevated so that the jaws m m, which passed over it in its first position, now come in line with it, causing said jaws 'to seize and hold the cord between them, and as they near the end of their revolution the spur t strikes the cutter S and causes it to sever the cord above the holder. The severed portion of the cord is then pulled out by hand and thrown away; or, if attached to the arm, the further movement of the arm pulls it out; but as the loop draws off of the jaws it closes on the strand held between them, and thereby forms a secure knot in-the waste piece thrown away. The machine is now put into the grain. The cut grain dumped by the conveyer upon the binding-table accumulates behind and against the compressor and separator J. The arm I passes upward andbackward over the accumulating grain and descends between the guides B into the slot B separating the quantity of grain necessary to form a gavel and sweeping it forward againstthe compressor, which yields and lies against the front and upper side of the bundle, when the arm I arrives at the tying mechanism and stops. The two strands of the cord are now caught by the looping head, and in the process of being looped around the head are forced into the open notch presented at the side of the disk to receive them, the holding-disk revolves partially around to clamp the cord and to raise the two ends of the band, the jaws come around, seize, and hold them, the cutter severs the cords above the disk, and the arm I, commencing again to move forward, positively ejects the bound gavel, thereby drawing the loop from the looping and tying head and forming the knot in the'band, as above described. As the bundle passes out from under the compressing arm or rod J the latter quickly springs back, effectually separating the coming grain from the old discharging-gavel. In this it is aided by the inclined position and rising movement of the cord held by the end of the arm I. As the latter moves forward and upward the cord carried by it swings upward and backward over the inclined face of the shoulder or detent b by which it is held in proper position to insure the operation of the holder and looper at their next succeeding rotations. The projecting undercut end of the plate 0 operates as a guide to carry the cord between this plate and the disk, and also as a detent to prevent the backward movement of the arm I from drawing the cord out of position on that side of the notch.

It will be observed that the inclination of the disk N to the looping-head performs important functions in this machine; but as I have in another application contemporaneous herewith broadly claimed such inclination, I limit myself herein to the improvements in construction and combination, as set forth.

I claim as my invention- 1. The notched disk N, roughened or serrated on its flat under side, in combination with the plate 0, or an equivalent thereof, and with the looping and tying head, substantially as described.

2. The vibrating cutter, combined with the rotating looping-head, the fixed plate 0, and the rotating disk N, notched at its edges and roughened or serrated on its under side, substantially as described.

3. The combination of the oblique shafts e e, the inclined notched or roughened disk N, the fixed holding-plate O, the cutter, and the lodping and tying head, substantially as described.

4. The adjustable plate 0, combined with the notched and roughened plate or disk N, substantially as described.

5. The combination, to form a cord-holder to automatically seize the cord and iutermittingl y take a fresh hold, of a smooth-surfaced clamping-plate and a superposed rotating notched disk having its flat under surface contiguous to said plate, and formed with ratchet-teeth set forwardly or against the stress of the cord.
