PATENT SYLVAN B. ROBBINS, OF LAWRENGEBUBG, INDIANA.
GRAIN-BINDER FOR HARVESTERS.
SPECIFICATION forming part of Letters Patent No. 271,126, dated January 23, 1883.
Application filed June 10, 1882. (ModelJ u To all whom it may concern Be it known that I, SYLVAN BALDWIN R013- in the county ofDearborn and State of Indiana, have invented a new and useful Improvement in Grain Binders for Harvesters, of which the following is a full, clear, and exact-description, reference being had to the annexed drawings, forming part of this specification.
This invention consists of a grain-binder in which an oscillating needle is combined with certain rotary and oscillatory-devices operated by a rack-bar which is connected to the elbow lever carrying the needle, whereby the cord shall be held, tied,andout in binding the gave], as hereinafter fully described.
In the drawings, Figure 1 is a side elevation ofmybinding-mechanism,thegrain-tablebeing sectioned. Fig.2 is a view ofthe rotary head, showing its shaft and housing in section. Fig. 2% is an end view of the shaft of the rotary head and its housing. Fig. 3 is a plan of the cord-cutting device. Fig. at is a plan of the cord-gripping device. Fig. 5 is asectional view, showing the cam-groove ,for operating a part of the tying device. Fig. 6 is a plan of the mechanism for operating the gripping device; and Figs. 7,8, 9, 10 show different stages in the process of tying a knot.
A designates a portion of the grain-table, above which is pivoted the elbow-lever B, carrying the needle (3 at its upper end. To the lower end of the elbow-lever is connected the rack-bar D, which is adapted to slide horizontally in suitable guides attached to the under side of the table.
Above the rack-bar is journaled a shaft, E, arranged at right angles thereto,and carrying a pinion, F, which shaft also carries the rotary head or knot-tying device, G. The shaft is supported in the housing L, as shown in Fig. 2. In a longitudinal perforation in the said shaft is loosely arranged a. pin, H, which also extends through corresponding perforations in the pinion F and rotary head G, and is provided with a hook, it, at its projecting end, which is adapted to be drawn into a recess in the face of the rotary head. A spiral spring, I, surrounding a portion of the pin at the opposite end thereof from the rotary head is accommodated in an enlarged portion of the perforation containing the pin, and an intermit tent longitudinal reciprocation is given to the pin by means ofa transverse projection, J, on the pin, which works in a slot, '5, in the corre-' sponding end of the shaftE, and a cam-groove, K, formed in the bottom or lower half of the housing L, in which groove the projection is moved when the shaft is rotated. The upper half of the housing is recessed, as shown in Fig. 2?}, to accommodate the projection Jwhen not in the groove. in the lower part of the housing L, and has a sudden inward curve at its central and lowest part, as shown in Fig. 5, so' that the lug on the projection J,in passing through the groove will be moved inward and then outward at said point to cause the hook it to reach out and engage the cord and draw it against the face of the head G, as shown in Figs. 9 and 10.
The rotary head G is of a nearly cylindrical form, and is provided with two reversely-inclined hooks, g g, which are formed by a helical slot, g cut from the periphery nearly to the center of the head. Extending nearly around the heel of the longer or outer book, 9, is a groove, which is formed obliquely or spirally across the periphery of the head and terminates at a pointon the face, near the center thereof. The object of this construction is to provide a bed for the cord to holdit in a definite position upon the knotter-head while the loop and knot are being formed.
1m inedia-tely below the rotary head and the rack-bar, and projecting laterally therefrom, is a frame, M, consisting of an upper and a lower plate connected together, in which are supported two short vertical spindles, m on, having pinions m at their lower ends meshing with each other. Near the upper end of the spindle m are secured two parallel dish'shaped disks, rt, arranged at a slight interval apart, with their concave faces toward each other. The peripheries of the disks are provided with corresponding projections, n, arranged at regular intervals apart and inclined in the same direction.
To the spindle at, near its upper end, is se- This cam-groove is formed cured a single plane disk, n adapted to be rotated between the disks n, and having projections similar to those ofthe latter, which are designed, in conjunction therewith, to catch the ICC cord anddraw it between the disks, whereby it will be securely held.
The disks a are made dish-shaped in order to accommodate them to cords of difi'erent sizes, since a very small cord will beheld at the peripheral edges of the disks, while in case a larger cord is used the disks, which are to be made of spring-steel, will readily spread apart without losing any of the requisite binding effect upon the cord at the edges of the disk.
To the disks an intermittent movement, always in the same relative directions, is imparted by means of a lever, N, journaled upon the spindle m, and having a spring-actuated pawl, 0, which engages with a ratchet-wheel, 0, secured to said spindle, and a projection, P, on the rack-bar, which engages with thelever during the latter part of its movement in one direction. A retaining-pawl, Q, is also placed in engagement with the ratchet-wheel O, to prevent the latter from being accidentally rotated backward. After the lever N has been moved to a given position by the projection P it is returned to its normal position by a projection, P, near the opposite end of the rackbar. A given movement is thus imparted to the cord-holding device, which movement is made to correspond to that of other parts, as further explained.
To the upper surface of the frame M is secured a stationary blade, 12, under the edge of which a pivoted blade, 19, is made to oscillate to cut the cord after the gavel has been bound.
The blade p is provided with an arm, g, which is adapted to be moved to close the blades by the projection P, while the projection P, moving in the opposite direction, throws the pivoted blade back from the stationary blade. By the latter movement the arm q is thrown beyond the reach of the projection P, and in order to leave the arm in a position where it can be reached by the said projection, a catch, q, is formed on the blade which shall be thrown into the way of the projection P after the latter has passed a certain limit, and on its return it will strike the catch q, and by it move the blade 1) just sufficientlyto bring the arm q into the way of the projection P, and thus the arm will always be left in a position to be operated by the projection P whenever the latter is moved toward the former.
1 To the upper surface of the stationary blade 19 is pivoted a crooked finger, 1, having a retaining-spring, r,'and adapted to be oscillated by a lug, s, on the rack-bar, near the projection P, in such manner that the rack-bar shall close the finger and the spring shall open it. The object of this finger is to catch the cord and draw it within reach of the outer or longer book of the rotary head.
The needle 0 is provided near its point with a curve, P in the lower portion of which is the eye. The frame M is recessed to allow the needle to pass near enough to the knotting devices to enable them to engage the cord.
The operation is as follows: When the needle descends the finger r is oscillated by the simultaneous movement of the rack-bar and engages with and draws the cord inward toward the rotary head, as shown in Fig. 7, while the gripping device seizes the cord at a lower point and holds it firmly. As the needle begins to ascend the rotary head turns forward in the direction of the arrows in'Figs. 7 to 10. inclusive, and the outer hook engages tl e cord. At the same time the finger moves back out'of the way, and as the rotary head conshown in Fig.8, in which the inner book of the rotary head has engaged with the cord to prevent it from slipping back behind the outer book before the latter is in a position to control it. As the rotary head moves to the position shown in Fig. 9 the 'cord is crossed at the inner end of the slot and the hook projects from the face of the rotary head and allows the lower end of the cord to pass under it, where it is gripped and held until the rotary head reaches the position shown in Fig. 10, where the loop in the cord has slipped over the hook and tied the knot, which is completed by the loop slipping oif the end of the hook. The last movement operates the blade 19, which cuts the cord, and the ends of the cord are held by the hook it with sufficient force to draw the knot tight in disengaging the ends, when the sheaf falls.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s
