It is also provided at its end with a lateral projection, 1"", which engages with a locking-catch, 7' below the binding-table when the bindingarm is down.
- Said catch is hinged at one end, and is normally held down by means of "a spring, 1", but is adapted to be raised automatically by the engagement of a downward projection, r, at its end with an arm, 1, located on the reciprocating rake-frame F.
- S represents the spool or bobbin containing the binding-cord. It is held between bearings s s, the former of which is rigid, while the lat ter is mounted upon a spring, 8 and is capable of being adjusted by means ofa set-screw, .9 so as to bear with more or less pressure upon the ends of the spool, and thus regulate the tension.

SPECIFICATION forming part of Letters Patent No. 250,620, dated December 6, 1881. Application filed June 15, 1881. (N model.)
To all whom it may concern Be it known that I, JAooB W. WILsoN, of Summerford, Madison county, Ohio, have invented certain new and useful Improvements in Harvester-Binders; and I do hereby declare the following to a full, clear, and exact description of the same, reference being had to the ac- 7 is a detailed view of parts of the looping and tying mechanism. Fig. Sis a sectional view taken longitudinally through the platform. Fig. 9 is a perspective view of the raking-frame; Fig. 10, a bottom-plan view of the frame D D carrying parts ofthe binding mechanism; Fig. 11, a detail view, showing the rake-frame and the cam for raising the catch or pawl to release the rake-head and permit the rake-teeth to fall down. Fig. 12 is a view of part of the rake-frame. Fig. 13 shows the end of the rakehead and the devices for holding it when the teeth are elevated, together-with the cam for releasing it; Fig. 14, Sheet 3, a view of the binding-arm and its clamps. Fig. 15 is a perspective view of the bar T detached.
My invention has for its object to provide a harvester-binder in which the cut grain that falls upon the grain-platform shall be carried directly to a binding mechanism located at one end of the platform by means ofa raking mechanism arranged on the platform itself; and it consists in a machine embodying certain novelties of construction and combinations of parts, whereby my said object is obtained, which machine I will now proceed to describe.
In the drawings, Arepresents the main frame ofthe machine, mounted upon suitable wheels, B B, and not differing materially from the frame of an ordinary mowing or reaping machine, except thatitis formed with or has bolted to it a rearwardly-projeeting bar, (J, to which is adapted to be suspended by means of a bar, D, a platform, D, containing the cutting, raking, and binding mechanism of the machine, the said platform being further supported by a drag-bar, D, at its front edge, and a grainwheel, D, at its outer end, as shown.
E is a reel mounted upon a standard extending upward from the drag-bar, and receiving motion through an endless chain passing over a sprocketwheel on the end of its shaft, and also around a similar wheel fixed to the revolving main axle or to the hub of one of the wheels B, in the usual manner.
The platform D is preferably constructed of longitudinal front and rear bars or timbers, D D, end cross-bars, D D, an intermediate frame, D, carrying a part of the knotting mechanism, and a plate or table, D carrying on its under side other parts of the knotting mechanism, and constituting also the table onto which the sheaves are gathered and held while being bound. The under side of the platform, beneath the binding mechanism, is covered with a bottom, D, while its upper side, where the cut grain falls, is provided with a longitudinally-slotted top extending from the outer end of the platform to the binders table, as shown.
The front and rear timbers, D D, are provided upon their inner faces with longitudinal grooves or guides 01 d back and forth, in which is adapted to slide a rake-frame, F, carrying a rake-head, F, armed with teeth f, which are adapted to project up through the slots in the top of the platform. The rake-frame is connected to an endless chain, F which passes around a sprocket-wheel, F, at the outer end of the platform and around another sprocketwheel, F mounted upon a vertical shaft, F supported in a bracket, F, at the inner end of the platform. The shaft F is provided with a pinion, F, with which engages the racktoothed end of a pitman, F operated from a crank, F on the end of the main axle of the machine. The-rack-teeth of the pitman are kept at all times engaged with the pinion by means of a guide, F, that plays through an opening in an offset, F, of the bracket F", and which is joined at both ends to the pitman, as shown. The connection of the pitman to the wrist of the crank is not permanent, but the pitman is provided with a slot, F which enables it is to be engaged with or disengaged from the wrist, as desired, by the co-operation of an arm, G, projecting from a rock-shaft, G,
' and kept under the control of the driver of the machine from his seat by means of a foot-lever, G When the pitman is in engagement with the crank-wrist the vibration of the latter causes the pitman to vibrate back and forth and its racktoothed end to rotate the pinion and its shaft first in one direction and then in the opposite direction, thereby imparting to the endless chain a reciprocating motion and causing the rake-frame and its rake to advance toward and reeedefrom the binding apparatus. To arrest the operation of the rake it is only necessary for the driver to press upon the footlever G and elevate the arm G into the path of a lateral projection, g, on the end of the pitman, so that when the crank brings the pitman around the said arm will strike the projection and unship the pitman from. the wrist, thus breaking the connection. The rake head F has its bearings in the forward end of the rake-train e, and its extremities, projecting into the grooves d, form the supports and guides for that end of the frame.
When the rake-frame starts to move forward toward the binding mechanism acam or projection, f, near one end of the rake-head, strikes the upturned end of a stationaryspring,
f and causes the rake-head to be rotated until its teeth f stand up vertically through the slots in the platform, in which position they are locked from further movement in either direction by the engagement of a spring-catch,
f mounted on the rake-frame with a notch in an enlargement, f*, at the opposite end of the rake-head. Continuing to advance, the raketeeth gather the cut grain and sweep it up to and onto the binding-table into position to be compressed and bound into a sheaf. Having thus delivered the grain to the binding-table, the further movement of the rake-frame causes the spring-catch f to be lifted from engagement with the notch in the enlargement f by means of a cam, f, on the side of the bar or front timber, D thereby releasing the head and permitting the teeth, as they strike the intermediate cross-frame, D to be thrown down into horizontal position, where they remain until the rake-frame is reciprocated back to its first position or starting-point.
Extending upward from the front and rear timbers of the platform, at opposite ends of the binding-table,are two standards, H H, and at the upper ends of these standards is mounted a cross-shaft, H, carrying at or near its middle the binding-arm H A fixed curved arm, H rises from the rear side of the binding-table, a little to one side of theplane in which the hinding-arm moves, and to an extension or offset of the said fixed arm H is articulated a movable compressor-arm, H, (see Fig. 8,) having a laterally-projecting pin or stud, h,which is adapted to engage with a slot in a short arm, h, fixed to the shaft H, and against which the arm h of a spring, 7L3, coiled about the shaft H,is
also adapted at certain times to bear. Ayielding spring-arm, h, is attached to the arm H as shown.
Securedto the end of the shaft H, at the rear side of the machine, is a crank, 7L5, and connected to the wrist of this crank is a bar, h,which in turn is connected to the short arm of an angular bar, it, pivoted to the platform at h", and having an offset, 71/ at its outer end, and a cam-slot, h extending nearly its entire length. h is a pawl-arm, pivoted at h, and having anotch or shoulder, h, which at certain times is adapted to engage with the offset h", and having, also, an extended weighted end,which, when the notch is engaged with the ofi'set, extends over the bar h and across the slot there- Arranged at the rear side of the platform, and connected to the sliding-rake frame in any suitable manner,is a bar, i, the same extending along the platform some distance, and having at its forward end a laterally-projecting pin, *5, as shown.
At thetime when the rake advances to sweep the grain onto the binding-table the bindingarm is in an elevated position and the slotted bar h is down, so that the weighted pawl engages with its ott'set and extends across its slot. The movable compressor-arm is also elevated, its lateral stud or pin it being held within the slot in the short arm h. Just before the rake-teeth begin to fall down into horizontal position after delivering the grain onto the binding-table, the pin 11 on the bar it enters the slot in theinclined portion of the bar h", strikes the end of the pawl-arm projecting across said slot, thereby disengaging the pawl from the offset, and, traveling along in the inclined portion of the slot, causes the bar to be elevated, and through the connecting-bar h and crank h causes the shaft H to be rotated. Soon after this shaft begins to rotate, and while the binding-arm is sweeping down, the pin it becomes disengaged from the slot in the arm h, and the end of the coiled spring 7L3 strikes the said pin and causes the compressor-arm H to grasp the collected grain, form it into a bun dle, and hold it with yielding pressure against the spring-arm h, after which the binding-arm passes the cord around it, as will be presently explained. The force with which the spring It bears upon the compressor-arm H may be regulated by adjusting the sleeve or ring to which the inner end of said spring is connected, and securing it by means ofa set-screw,
The knotting mechanism consists, mainly, of a longitudinally-sliding but non -'rotating tube, K, around which the cord is wound to form theloop; arotatin g outer cylinder or tube, L, carrying a pair of spring jaws or nippers, l l, which grasp and hold the end of the cord while it is being looped about the inner tube, and a central longitudinally-sliding hook-bar, M, and co-operating bar N, which securely grasp the end of the cord lying across the formed loop and pull it through the loop and within the inner tube, so as to complete the knot and draw it tight.
The outer rotary cylinder or tube, L, is preferably mounted in hangers or bearings depending from the under side of the binding-table, and has a pinion, i upon its outer end, with which engages the teeth of a vibratory rackbar or toothed segment, 0. On the forward end of said tube L thejaws or nippers Z Z are mounted. Thescjaws are preferably ofspring metal and of sufficient rigidity to hold securely a strand or strands of cord forced between them, and the outer jaw, I, has a stud or projection, 1 on its innerside,which passes through a perforation in the innerjaw, l, and projects inward a short distance beyond the latter.
The inner non-rotating tube, K, extends longitudinally through the outer tube, L, and has secured to its rear end an arm, it, while on its front end it is provided with a radial projection, k which at certain stages of the tying operation is adapted to engage with the stud l on the clamping-jaw Z, to open said jaw and permit the entrance of the cord between the twojaws. The said projection k is also adapted to enter a longitudinal slot in the outer tube, L, when the latter is stationary and the inner tube is moved longitudinally, as will be presently explained.
The central retracting hook-bar, M, extends through theinner tube, K, and is curved around at its rear end and bifurcated to receive the lower end of the arm 7- of the tube K. It also has a pin, m, which engages with an arm, Q, pivoted at q and having a spring on its pivot operating to press the arm inward.
The bar N, which co-operates with the hookbar M to clamp and draw inward the end of the cord, lies alongside the bar M in the tube K, and has a downwardly-projecting arm, n, at its rear end, against which a spring, n bears, so as to exert a forward pressure upon the bar.
The toothed vibratory rack-bar or segment 0, which rotates the pinion of the tube L, is articulated to an arm, 0, mounted upon a post or stud, 0, and to the lower end of this stud 0 is secured a bell-crank lever 0 one arm of which is slotted at 0 and has an extension, 0 and the otherarm of whichis provided with adownwardly-projectin g pin, 0 A vibratory motion is imparted to the bell-crank by means of a projection, 0 on the reciproeaiin g rake-frame engaging with the slotted arm of said lever, and by an arm, 0, projecting from said rake-frame and cooperating with the downwardlyprojecting pin 0 on the bell-crank lever. .Two projections, 0 and 0 are formed upon the front side of the rack-bar, one of which, 0 operates to throwinto action a pivoted cutting-knife P, when the rack-oar is vibrated in one direction, and the other of which, 0 serves to throw said knife out of action when the rack-bar is vibrated in the opposite direction.
The binding-arm, at its outer end, is provided with a cord-clampin g device, It, consistin g, preferably, of two'thin metal fingers, "r 1',
held closed together bytheir own elasticity, and flared a little at their outer ends to illsure the entranceof the cord between them. Said arm is further provided with a curved arm, 1", which, as the arm descends, bears upon the top of the binding-table, and carries into a slot in the table the binding-cord. It is also provided at its end with a lateral projection, 1"", which engages with a locking-catch, 7' below the binding-table when the bindingarm is down. Said catch is hinged at one end, and is normally held down by means of "a spring, 1", but is adapted to be raised automatically by the engagement of a downward projection, r, at its end with an arm, 1, located on the reciprocating rake-frame F.
S represents the spool or bobbin containing the binding-cord. It is held between bearings s s, the former of which is rigid, while the lat ter is mounted upon a spring, 8 and is capable of being adjusted by means ofa set-screw, .9 so as to bear with more or less pressure upon the ends of the spool, and thus regulate the tension. From the spool the cord passes through a perforation, s, in a plate of the intermediate frame, and thence to the clamps on the bindingarm.
T, Figs. 4 and 15, is a centrally-pivoted lever, carrying at its rear end a wedge-shaped projection, t, which is adapted at certain intervals to rise and spread apart the clamps on the binding-arm, so as to admit the second strand of cord more readily. The front end of said lever is bentdownward, and is provided with a lateral projection, t, which is adapted to engage with an incline or cam, t on the reciprocating rake-frame when the latter moves toward the binding-table, for the purpose of throwing the rear end of the lever and its wedge-shaped projection upward. A spring, 15 beneath the forward end of the lever, keeps the rear end normally depressed.
Mounted upon a laterally-projecting stud on the top of the rear standard H is a bundle ejector or kicker, U, shaped somewhat like a pitchfork, and kept normally elevated by the action of a spring, a. A spur, u, is formed upon or secured to the base of the crank If, and cooperates with a projection, u on the ejector, to cause the latter to sweep toward the rear of the machine and carry off the sheaf or bound bundle from the binding-table.
From the foregoing detaileddescription the operation of the machine will be readily understood. NVhen the machine starts to operate the binding-arm stands in an elevated position with the end of the cord held in its clamping device, while the rake-frame is at the outer end of the platform. As the machine advances the rake-frame is reciprocated toward the bind ing-table by the mechanism before described, and the elevated rake-teeth sweep the out grain up to and onto the binding-table against the springarm h Just before the rake-teeth descend to a horizontal position, the laterallyprojecting pin t" of the bar i enters the slot of ICC the pivoted bar it, releases the pawl-arm from the offset, and, through the medium of the bar If, connecting-bar h, crank If and shaft H, causes the-movable compressor-arm and the binding-arm to one after the other descend, the former compressing the grain into a compact bundle, and the latter passing the cord around thesame, the curved arm r carryingthe cord into the slotc in the binding-table,where the firststrand of cord alreadyis. As the end of the binding-arm passes down under the hinding-table the projection 1" on the rake-frame raises the spring locking-catch v and permits the lateral projection r on the binding-arm to pass thereunder and be locked, thus securely holding the binding-arm. The clamps on the binding arm have meanwhile caught the second strand of cord between them, and both strands have been carried in between the spring jaws or nippers Z l of the knotting mechanism, which are held open by the engagement of the stud l of thejaw Z, with the radial projection k on the inner tube, K. Immediately after the binding-arm has been secured by the lockingcatch, as aforesaid, or simultaneously with its being so secured, the cam t on the rake-frame operates the lever T, so as to cause its wedgeshaped projection 25 to rise and open or spread apart the clamps of the binding-arm, to enable them to take a firm hold upon the second strand of cord, after which the wedge-shaped projection 0 on the rake-frame strikes the slotted arm of the bell-crank lever o, and, through the medium of stud 0 and arm 0, causes the rack-bar or toothed segment 0 to rotate the pinion Z and the tube L, to which it is secured. As the tube Lbegins to rotate,its clamps or nippers ll close tightly and hold the two strands of cord, and soon thereafter the projection 0 on the rack-bar strikes the pivoted knife P, and causes it to sever the strands of cord close tothebinding-armclamps. Thecylinderortube L revolves about one and one-half time around, its clamps l l holding securely the ends of the cord meanwhile. During its first revolution it carries the cord completely around the end of the inner tube, K; but when this is accomplished the stud 0 on the rake-frame strikes the end y of a spring-detent, Y, located on the under side of the frame, and disengages said detent from the downwardly-projecting arm k of the tube K, after which a cam, v, on the back of the rack-bar O strikes the said arm 70, and pushes the tube K a little backward longitudinally,so thaton the neXthalf-revolution thecord will not be wound about the tube K, but will cross itself and be drawn over the end of said tube and behind the exposed hook of the hookbar M. The continued movement of the rakeframe causes it next to strike at the point to the bifurcated end of the retracting hook-bar M and force said bar backward, its hook end pulling the ends of the cord completely within the tube K and against the forward end of the co-operating bar N, the spring a at the rear of the latter operating to hold said cord ends securely and positively. A projection, 20, on the rake-frame then strikes and moves backward the spring-arm Q, and the latter then, by its connection with the pin on the end of bar M, forces still farther backward both the tube K and the bars M and N, the radial projection on the said tube sliding into the longitudinal slotin the end of tube L. As the tube K thus moves backward the loop of cord around its end is pushed off by the stationary outer tube, L, after which the bars M and N, still holding securely the ends of the cord, pull the knot tight, thus completing the operation. Upon the movement of therake back to its first position the bars M and N release the ends of the cord and reset the binding mechanism, as will be readily understood. During such resetting movement, however, the kicker or ejector U is operated, and catching the bound bundle with its teeth discharges it endwise from the machine.
The raking mechanism is pref rably so constructed and geared as to cause it to gather the grain and set in motion the binding mechanism every-twelve or fifteen feet as the machine advances; but should the crop be light, the driver, by operating the foot-lever and disconnecting the slotted pitman from the drivingcrank, can cause said mechanism to operate less frequently, or keep it out of operation altogether as long as desired.
It will be observed that in this machine the binding mechanism is operated entirely and directly by the raking mechanism, and that the latter is not set in motion until the proper amount of cut grain has accumulated on the platform. This I regard an important feature, as by it the bundles or sheaves are kept of uniform size and more satisfactory Work is performed.
, The main frame of the machine is so constructed that the platform D can be detached, when desired, and the proper parts of an ordinary mower or reaper be attached in its place. This is an economy to the farmer, as it renders it unnecessary for him to have but one main frame and driving mechanism to operate his several machines.
While I have described herein a mechanism adapted to the bindingofgrain with cord alone, it is evident that with slight adaptation a wiretwisting device might be substituted for the knotting arrangement, and wire used as the binding material instead of cord.
The proper adjustment of the platform may I be effected by means of the set-screw Z, which clamps the suspending-bar to the rearwardlyextended beam of the main frame.
If desired, a small caster-wheel may be provided to assist in supporting the inner end of the platform at its rear side.
