SPECIFICATION forming part of Letters Patent No. 307,176, dated October 28, 1884.
Application filed June is, ices. (Modem have invented certain new anduseful Improve- -n1ents in Grain-Binding Apparatus; and I do hereby declare the following to be a full, clear,
and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of thi specification.
Figure 1 is a top plan view of the knotting devices, part of the slotted breast-plate being broken away. Fig. 2 is an outer side View,
partly in section,the section being taken in .Figs. 7, 8, and 9 are details showing the three movements of the cord-guide.
This invention relates to improvements on cord tying and knotting. devices, which are used in connection with other devices, the whole constituting a mechanism for binding grain on a harvesting-machine, which improvement will be fully understood from the followat b, and on the other end of this shaft is keyed a compound cam and gear wheel, B.
D designates the knotter, which projects at the bed-plate A.
right angles from its vertical shaft D, that has its bearings in portions of the standard A, and which has keyed on it a beveled spur-pinion, E, adapted to engage at times with a number of teeth, 01, on the face of the cam and gear wheel B, which revolves the knotter. This knotter consists of a fixed lower'barbed cut ting-jaw, e, and an upper grooved jaw, e, which is pivoted within and plays in a slot in the upper fixed jaw, so that its grooved and beveled edges will drop on the point of the said barb.
On the upper end of the knotter-shaft D is keyed a tappet, F, which is acted on by a concentric cam-rib on the face of the cam-wheel B, and also by a striker, f which is on the end of a bent arm that is fixed to the wheel 13 alongside of the cam-rib f There is also a delay-shoe, F, on the knotter-shaft D, below the tappet F, the fiat surface of which bears against the rib f on cam-wheel B, and positively holds the knotter D in proper position to receive the cord, after which the shoe F is released from rib f, and acted on by lug f Below the knotter D is the bifurcated cord tucker or placer H, which vibrates across the curved and enlarged portion of the slot through This cord-placer vibrates upon a stud orpin, g,'which is fixed to the breast-plate, and its angular arm has an antifriction roller, 9*, on it, which works in the cam-slot g in the periphery of the wheel B,the general form of which is represented in Figs. 1 and 2.
I will now describe the device for grasping and holding the cord at proper times during the formation of the knots.
K designates a horizontally-vibrating bell crank lever or frame, which has its fulcrum on a stud, h, fixed to the breast-plate A. From one arm of the lever K rises perpendicularly a post, on which is an anti-friction roller, I, arranged to bear against the edge of the flange b of wheel 0 and prevent vibration of the cord-holder during the greater part of the revolution of said wheel. The free end of the longest arm of the holder-lever K has a vertical grooved and beveled end, 6, formed on it, and this grooved and beveled end constitutes the rigid jaw of the holder and vibrates be-- ico of the bar L has an anti-friction roller, 1, applied on it arranged in the path of a cam, M, v
which is on the end of a long radial arm or sweep, M, secured rigidly to the inner side of the flanged wheel C at the point where the notch l/ is made in the flange b. At the proper time during each revolution of the wheel 0 the cam M will strike the anti-friction wheel I and retract the grasper-bar L and release the cord, which, when it is released, will be returned to its place by the spring T.
' Having thus described the construction and arrangement of my knotting devices, I will now describe the operation of the same. The
, end of the binding-cord, after being passed through the eye of the needle, is placed in the cord-holder. The needle shown in dotted lines in Fig. 3 recedes and lays the cord over the knotter-hook and in between the fingers of the cord-placer. The needle then remains down until a sufiicient quantity of grain accumulates in the receptacle of the binder to start the binding mechanism, when the needle moves forward and brings the cord around the bundle and between the fingers of the cord-placer, and, by means of the crooked slots in the cam-wheel B and the roller on the arm of the cord-placer, this placer is then vibrated,
so that it stands with its fingers about at right angles across the slot through the breast-plate A, whereby both strands of the binding-cord are held down within reach of the knotterhook. The knotter-hook is nowvcaused to make a revolution, looping the cord around which is now in the same position it was before its revolution. \Vhen wheel B moves far enough to release the knotter-pinion from the segment d, the tappet F on the shaft of the knotter-hook is struck by a lug, on wheel 13 and turns the knotter one-half a revolution backward, so that the knotter-jaws point outward from the machine, and when the discharge-arms Z Z throw the bundle from the machine the knot is pulled off the hook and tightened. The pivoted compressing or holding jaw in the knotting-hook is without an inwardly-extending heel, and when the knottinghook is turned so that its jaws turn outward in the direction of the discharge for the purpose of letting the discharge-arms strip the knot therefrom the cord placer or guide is also turned outward, so that the cords may slip out of said placer or guide, and as the wheel B revolves the knotter and the cordplacer are thrown back into their original position, ready for repeating the operation on another bundle. \Vhile the gavel is being packed into the grain-receptacle the cordguide stands up in the position shown in Fig. 7, and the end of the cord is held in the cordholder, when the binding mechanism is tripped into gear and the eye of the needle is brought over far enough to bring the upper part of the cord within the fork of the cord-guide, the guide drops, as shown in Fig. 8, and brings the two strands of cord down over the knotter-hook. The lower part of the guide is designed to hold the cord in proper position;
When the cordguide drops down, as shown in Fig. 9, it slackens the under cord and relieves the strain, so that the cord will be in no danger of breaking. The projection if is intended to hold the cord back, so as to form the loop near the back part of the knotterhook, and thus give sufficient room for the two cords to enter the jaws of the knotter hook. WVhile the needleis at rest and the packers are packing the grain, the'flange-wheel 0 holds the grasper until the binder is started. This wheel continues to turn until the notch b in its flange is opposite the roller I of the grasper-leveiyat which moment the knotterhook commences to revolve, and by the winding of the cord around the hook it pulls the cord-holder up toward it, and at that instant the beveled piece or cam M strikes the roller 1 and opens the jaws of the holder and releases the end of the cord and takes the other part of the cord again near the end of the needle bythe action of spring T closing the adapted to operate substantially as described.
2. The combination of the forked cordplacer H, vibrated by means of a slot in camwheel B for delivering the cord to the knotter, and the breast-plate A, having a curved slot, .a, through it, substantially as described.
3. The revolving knotter having a lower rigid jaw provided with cutting-barb e, an upper rigid j aw, c and a grooved-edge tongue, 6, pivoted therein, in combination with a pinion, E, tappet F, a delay-shoe, F, and a camwheel having concentric ribs, a lug, and a toothed segment on its face, substantially as described.
4. The combination of the yielding cordholder frame K, having a grooved-rigid jaw on one end, stops on the breast-plate, a springactuated bar carrying the movable jaw and the anti-friction roller, the cam-flanged wheel cutter, the vibrating forked cord-placer, and 10 0, having a notch in its flange, and the cam M the gear and cam wheel B for operating the opposite thereto, adapted to retract said bar, knotter and placer, substantially as described.
