' MOSES A. KELLER, OF LITTLESTOWN, PENNSYLVANIA.
IMPROVEMENT IN GRAIN-B''NDERS.
Specification forming part of Letters Patent N0. 200,54l4, dated February 19, 1878; application filed July 14, 1877. i
To all whom/ it may concern: y
Be it known that I, MosEs A. KELLER, of
Littlestown, in the county of Adams and State' of Pennsylvania, have invented certain new and useful Improvements in Automatic Grain- Binders; 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 pertains to make and use it, reference being had to .the accompanying drawings, which form part of this specification.
My invention relates to an improved automatic grain-binder for harvesters, in which cord or twine is employed as the binding material; and has for its object the provision of such devices as shall receive and take from the platform of the receiver or harvester a suitable amount of grain, shall compress the same into a gavel, and bind it, ready for delivery to the ground. i
Figure l is a vertical side view, showing the whole'plan of the binding-head, and a longitudinal section of the platform. Fig. 2 is a vertical front elevation of the binding-head, with a transverse section of the platform. Fi g. 3 is a plan view of the horizontal mechanism, with part of the platform removed. Fig; 4 is a plan' view of a part of the binder mechanism. Figs. 5 and 6 are internal views of the head disk; and' Figs. 6, 7, 8, 9, 10, 11, and 12 are detail views of different parts of the mechansm.
A represents the binding table or platform, and B the driving or Operating shaft, which has a bevel-pinion, C, on its inner end. This pinion meshes with the large bevel-wheel D, on the lower end of a Vertical shaft, E, which operates the binding-head mechanism, and which wheel D is provided with a wrist-pin, F, that passes through oneend of the slotted lever G. Pivoted in the outer end of this lever G is a catch, H, having a projection I, on its inner side, and which projection passes through-a mortise in the side of the lever Gr,
I so as to project across the slot, as shown.
Bearng against 'the end of the catch H is the spring J which holds the catch pressed tightly against the side of the lever Gr, so as to keep the projection pressed inward across the slot, and so that when the cranked lever K forces the inner end of the catch outward it will snap back to place again. This cranked 'lever Kis pivoted in a mortise through the,
inner end of the lever G, and is operated by a proj ection, L, on the inside edge of the frame A. v As the lever Gr sweeps around, one end of this lever K strikes against the proj ection, thereby forcing it backward, which movement forces the inner end of the' catch H outward,
so as to withdraw the projection Ifrom across:
the slot in the lever G.
Pivoted to the frame A, at any suitable point, is the lever M, which moves the shuttleframe Nback and forth, and which has its inner end fastened to the frame' N by means of-a link or other suitable device. opening or slot near the outer end of this lever is passed a bolt or pin, O, which passes through the slot in the lever Gr. As the wheel D sweeps around, the wrist-pin F, through the slotted lever G, moves the lever M back and forth, in such a manner as to cause the shuttle-frame N to reciprocate back and forth in its bearings, .alternately moving and standing still, while the wheel D continues to revolve. While the bolt O is held at the inner end of the slot in the lever G, by means of the projection I, the lever M is made tomove the frame M; but as soon as the crankcd lever Ktrips the catch H, so that the projection I releases the bolt O, the bolt moves freely in the outer end of the slot without causing the lever to move until the catch again gets behind the bolt, when the lever M and frame N are again moved..
By the above-described mechanism the frame N is moved forward to have the loop formed, stands still while the knot is being tied, and then moves back again after it is done.
Pvoted to one corner of the bearings P, in which the frame N moves back and forth, is the bar Q, which has a number of cogs formed on its under side for Operating the shaft R, which has a segmental pinion, S, near its center, an enlarged recessed head, T, on its inner end, and a hook, U, on this head, for catching the strings and drawing them around with it as the shaft revolves. There are just enough cogs on the bar and the pinion to cause the i shaft R to make one complete revolution-no more, no less.
As the frame N moves either forward or Through an back; as long 'a flat part of the-bar rests upon the cut-away portion of the pi'nion the shaft stays still; but as soon as the pinion reaches the rock, the shaft at once begins to revolve.
Rigidly secured to one of the bearings, to one side of the frame N, is the switch-plate V, which has a suitably-shaped I recess in each side, and in these recesses are pivoted the spring-switches X X', of such shape as will give the loop-former a and cutter b their necessary motions. The loop-former a consists of a straight bar or rod, having its inner end recessed vertically, so as to catch the string, and a deep recess formed horizontally into its end, so as to divide the end into two prongs, each of which has a groove in its top to receive the string as the string is forced against them. As the' frame N is moved,the roller W, on the under side of this former, catches between the side of the recess in the switch-plate V and the switch X, and forces the former forward, so that its end enters the recess in the head T, carrying the stringwith it. Just as this former enters the head, the head is made to revolve entirely around the former, at which time the string is released, the cutter again comes forward, catches the string, outs it, and holds one end, and the hook U catches the string while it is thu"'s held in the head, so as to bring the two ends of the string around over the top of the former, just opposite the'horizontal recess in its end. Just before the head completes its revolution around the former the motion of the frame N causes the friction-roller on top' of the cutter b to move in the switchplate, in such a nanner as to force the outter b forward against the string and cut it off. The end of this cutter is so shaped as to catch the string and carry it forward without any danger of its slipping off, while the under 'side of this end is roughened, so as to hold the stri g while the binder-arn carries the string around the sheave. Pressed forward against the end of the cutter b by a suitable spring, c, is a holder, d, ;which presses the string against the end of the cutter, and helps to prevent the string from slipping. The switch-plate may be cast with the hearing.
` Bigidly secured to one end of the frame N is a guide, e, in which the plier-jawsf move back and forth. Upon the top of the rear end of the movable jaw is a small proj eetion, which catches in the under side of a switch-plate, g, in which there is also placed a spring-switch. Upon the rear end of these jaws is a frictionroller, i, which is made to catch, bythe motion of the frame N, behind the hook h, to draw the jaws back after they have been forced through the opening through the end of the 'ormer. Just before the frame N reaches the end of its motion toward the hook h, the
M switch-plate g causes the jaws to open as they pass through the end of the former, so as to catch the two ends of the string.
As the frame moves back, the roller is held by the hook just long and hard enough to cause the switch-plate to close the jaws, and thus grasp the two ends of the string and draw them through the loop into a knot. Upon the end of the switch-plate g there is a suitable projection, 0', which preven ts the jaws from opening too soon, as they` would otherwise do, and thus the knot not be drawn tight enough.
The'vertical shaft E passes up through the hollow standard j, and has a gear, k, on its upper end, for meshing with a similar wheel, l, on the end of a horizontal shaft, m, which operates the binder-head mechanism. The horizontal part of the hollow standard J has the gear-case n fastened to it near its end, and upon its end isthe segmental stationary wheel p, which has a portion of the cogs upon its periphery cut away, just opposite a portion of a 'circular guide, q, on the inside of the case n.
To the inner end of the shaft m is Secured the disk r, upon the inner side of which disk are the two wheels s t. The wheel s is the larger of the two, and moshes with the wheel 19, for the purpose of communicating its motion to the smaller one, t. The wheel t is secured to the rear side ofa disk, v, which revolves in an opening made through the face of the disk 1', and which has its face fiush with that of the disk. Upon the side of the wheel tis a semicircular guide, u, which, as the disk r revolves, catches over the top of the circular guide q, so as to hold both wheels s t stationary while they are'passing that portion of the wheel 1 where the cogs are cut away. i
To the disko is secured the eccentric wristpin w, upon which is pivoted both the binder arm y, compressor z, and spool 1. The binder-arn is of a single thickness of metal above the pivot, and about three thicknesses below, so as to form a groove for guiding the string, and to receive a pulley at its lower end. Above the pivot is made a longslot, 1, which acts as a guide for the upper end of the rod 2, which connects the binder and compressor arms together, and causes them to act in unison. Pivoted to the top of the curved portion of the compressor-arm is a rod, 3, which has its upper end pivoted to the lower end of a second rod, 4. The upper end of this rod 4 has its end Secured in a slot, 5, in the upper end of the binder-arn y.
Upon the top of the gear-ase n is formed a hearing, and in this bearing is pivoted a hub, 6, which has a suitable reoess forned in its face for the upper part of the binder-arn to slide up and down in. To the front of this hub 6, and over the front side of the binder arm, is secured the cam 7, which has an opening made down through its top, of the form shown. To the front of this` can is fastened the flat spring 8 which serves to force' the head of the rod 4 over into the bottom of the cam 7 and hold it there for the time being.` On the outer side of the rod 3 is placed ablock of rubber, 9, or other suitable spring, against the inner side of which presses the lower end of rod 4. Should there be an unusually large gavel taken in between the'binder-arm and the compressor-arm, the joint between the two rods 3 4: and' this spring will allow the com pressor-arm to give or yield.
The string is drawn from the spool, passed through the slot 10, down through the groove, and around the pulley. When the disk r begins to turn, the binding and compressing arms are far apart, and the binding-arm assumes an inclined position, so as to sweep the grain into a gavel. As the disk continues to turn, thetwo arms assume an 'upright position, and their lower ends move toward each*other, and the connecting-rod 2 has its upper end moved from the bottom to the -top of the slot 1, as shown in Fig. 1. The knot is then tied by the mechanism already described. As long as the upper end of this rod 2 bears up against the under side of the cam 7, and the upper end of the rod 4 is held down to the bottom of the slot 5 in the top of the binder-arm and the bottom of the opening in the top of the cam 7, there is no yield to either binder or compressor arm, except what the spring 9 allows the compressor-arm for large bundles. As the disk continues to revolve and begins to raise the two arms upward after the knot has been tied, the uppcr end of the rod 4 is forced upward out of the recess in the top of the cam, and then the binder-arm begins to be forced upward through the hub 6. As the binder-arm rises, the upper end of rod 4 rises in the slot 5 at the-'same time that the under side of the cam 7 forces the npper end of the rod 2 downward, thereby separating the two arms and getting them ready for the next .bundle. Until the spool reaches its highest point the string is being nnwound; but as soon as it begins to descend, it revolves in the opposite direction, so as to take up all slack. The line of travel through which this spool passes is shown in dotted lines in Fig. 1; and as the binder and compressor arms are pivoted on the same pin, it is evident that they travel on the same line.
Instead of the shuttle-frame being made to operate back and forth, this frame may re main stationary and the bearings be made to move.
In building full-sized machines I follow the latter plan entirely, as being cheaper and better.
Having thus described my invention, I claim- 1. The lever G, slotted a portion of its len gth catch H, spring-cranked lever, a tripping device, L, and an Operating-lever, provided with a piu or projection, substantially as shown, the parts being combined for operation, as described.
