SPECFICATION forming part of Letters Patent No. 398,921, dated March 5, 1889.

Application iled April l, 1886. Serial No. 197,436. (No model.)

To all 'trimm it muy #01m/2m Be ity known that we, WILLIAM N. Wurm- LEY, WILLIAM BAYLEY, and Oscar. E. PER- RIGO, citizens of the United States, residing' at Springfield, in the countiAv of Clark and State ot' Ohio, hare invcntedceriain new and useful Improvements iu Grain-Binders; and we do hereby declare that the following is such a Inll, clear, and exact dei cfiption of the saine as to enable any person skilled in the art t which our invention pertains to construct and operate the saine, reference being had to the accompanying drawings, forming a part of this speciiication.

Our invention relates, in general terms, to that class of automatic grain-bi ndingharvesters wherein the grain is bound between the grain-platform and the main driving-wheel;

and it consists in the construction and arl rangement of the various parts composing the mechanism for elevating, lgiinding, and ldischarging the cut grain, and in the devices provided for driving the same, as hereinafter more particularly described and pointed out.

In the drawings, Figure l is a perspective View of our machine as a whole. Fi g. is a front elevziition, Fig. is a rear elevation, and Fig. i is a transverse section, of the machine, the grain-platform, reel, te., being omitted. Fig. 5 is an enlarged View of the trip or sctoff device for throwing the binding meehanism into and out of gear. Fig. G a scctional plan o'l the packer-shaft and its appendages. Fig. '7 is a perspective View of the startenpawl, and Fig. 8 is a longitudinal seetion of a modification of the elevator-belts and parts et the binding device.

Several parts not necessar)v to the proper understamling of the machine are omitted in oneor more views to avoid needless complications.

Similarletters refer iolike paris in the severa-l Views.

A A is the main trame el' the machine, lo which the main wheel i3 is journaled in the usual' manner. to it the bevel-wheel B2, which engages the bevel-pinion Bi on the eounter-shaft o, upon the outer or rear end oi' which is l'ixed the spur-gear B", engaging the spur-pinon Bf on the crank-shaft h2, upon the opposite or front The main wheel l has fixed l end of which is fixed the ily-wheel B, from lt'heitixed wrist-pin ZP' oi" which extends the pitman o* to the cutter-bar b5, shown, and as usuali;-v arranged.

Formed upon the spur gear-wheel B", cast l in one piece with it or secured to it or to the l Counter-shaft l1, is the sprocket-wheel C, from l which power is lu'ansmiitei'l by the chain c C t0 the sprocket-wheel for driving the elerating, binding, and discharging mechanism, i, to the sprocket-wheel C for driving the platform or convener-belt, and tothe sprocketwheel C" for driving the reel. The reel D D l is operated through the medium of the shaft l of, bevel-gears c3 and if, sprocket-wheels C, C, CT, and CS, and chains c and ci, and is prog vided with the adjusting-lever ci and its appen (leges, all arranged in the usual manner.

A`l A3 A* A5 A A Ag are the parts composing the upper fra-me, which is attached to and forms a part of the main frame A A, and incloses and supports the elevating, liinding, and discharging mechanism, as well as furnishes the support for the reel D, while upon the seat-board AS is fixed the drivers seat Z, all in the usual manner.

The platform E and its appendages are construct-ed' as usual, iixed to the main frame, and supported at the grain end by the usual grain-wheel, E2, attached as ma y be most con- Veniet.

The elevating, binding, and discharging mechanism is supported by a 'frame-work composed of the side boards, F F, cross-barF2 F3, deck-supports F, brace F5, middle rails, F, breast-plate FT, and frame-plates FS. This frame is supported within the upper portion of the main frame as Vfollows: Fixed to the sill A ot the main trame is the gas pipe or tube f, upon which rest the friction-wheels f2 f2, pivoied to brackets fixed to the side boards, F F. Fixed to the frame-plates F" is the gas-pipef, iis ends projecting forward and back,a11d sliding loosely through the boxes fAl f1", fixed 1o the posts Jb and Af. Fixed to the outer sill of the main `frame. is the upwardlyprojecting bracket u, harin g pivoted in it the i'rietionwheel a?, upon which rests the giri; 60". fixed to the under side ol' the discharge-deck O, which is kept from rising out of place by a portion ot the bracket rl being looped over I the well-known plan described in Letters Pat- V6) is driven by the chain c, passing over the ICI the girt a. The adjustment of the binding mechanism in its relation to the cutting mechanism, to suit the Varying lengths of g1 ain, is thus secured, and is controlled by the cranklever d, shaft cl2, and pinion (Z3, engaging the rack d"xed to the gas-pipe f3 in the usual manner.

The elevatorbclts V V2 are constrnctedas usual, except that the upper one extends only about half the usual distance up the incline, and that the belts are divided-'ll c., each com'- posed of two belts running parallel to each other and far enough apart to admit of the free operation of the binding mechanism between them, as shown in Fig. 1. rlhe belts are driven by the rollers V3 V" and pass over the upper rollers, V5 Vj.

The binding mechanism is constructed upon ent No. 212,420, granted to John F. Appleby February. 18, 1879, modified to suit the requirements of this form of constructing and arranging the machine-to wit, binding the grain between the platform and the main driving-wheel. v

The binder-frame Q is fixed to the side board, F, and carries the knetter-shaft q, binder sprocket-wheel K, tyer-wheel W2, and knotter L The packer-shaft G (shown in detail in Fig.

sprocket-wheel C2, through which it passes and is permitted to slide freely, but is kept from turning thereon by the spline g, traveling in the slot g2 of the packer-shaft, as usual. The shaft is supported in the binding mechanism by passing through the frameplates FS F8, between which the shaft has forlned upon it two packer-cranks, g3 g3, to which are pivoted the lower ends of the packers G2 G2. The packers are suspended and kept in their proper paths by the links g4 g4, pivoted at one .end to the packers near their center and at the other to the frameplates F8. The packer-shaft G, rotating in i the direction of the arrow, moves the packers i alt ernately upward bctw( en the elevator-belts, g forcing the grain against the compressor l-l', and returning beneath the lower elevatonbelt, the points of the packers following, in direction of the arro'w, the dotted li nes, as shown in Fig'. 4. By this method of constructing and arranging the packers two important results are accomplished over the usual form, viz: First, the packer has a much longer and more direct throw against the grain, its ascent being a long, gradual, upward sweep, while it withdraws itself freely from the grain, with i no shearing motion, and travels quickly back to its first point in the most practically direct line; second, by so constructing and hanging t the packers they occupy much less space lonl gitudinally, and the main driving-wheel may I therefore be set much nearer the grain-plati form and a more proper balance of the machine secured.

The needleearm J is fixed upon the shaft j, which passes through to the front of the machine, where it has the arm j? fixed to it, by which itis operated by the pitman js, connecting at its upper end with the crank-wrist of the binder sprocket-wheel K in the usual manner. The needle-arm J is composed of three partsrpivoted to each other-ai. e., the needle-arm J proper, the curved back piece, J 3, and the .link J4. The back piece, J 3, has one end pivoted to the needle-arm proper and the other to the link J4, whose opposite end is pivoted to some lixed point of the binderframe. By this arrangement, when the needle-arm J is thrown up to encircle the gavel, the link J 4, swinging upon its fixed pivot, carries the end of the back piece, J 3, which is pivoted to it, into such a position that it shall form an arc of a circle in prolongation with the arc formed by the back of the needle-arm, from its point to the pivot of the back piece, J3, by which construction the needle-arm is practically as useful as the usual form,while it occupies onlyabout two-thirds of the space longitudinally that is usually required, and the main driving-wheel can be set that distance closer to the grain-platform. The operations of the needle-arm in its functions of encircling the gavel, carrying the bindingcord, presenting it to the knotting device, &c., are all performed in the usual manner.

The compressor H is pivoted at its lower end to a projection on the needle-arm J, while its upper end is supported by the link" H2, connecting it with the arm H3, iixed upon the compressor-shaft 7L, which passes through to thefront of the machine, where it has fixed to it the arm Il, operated by the spring connecting-rod 7b2 and cam-lever 71.3, whose friction-roller works in a cam-track formed upon the binder sprocket-wheel K in the usual man-` ner, with the exception that as the arm j? must be forced downward in the act of binding, instead of being drawn upward, (owing to the changed location of the binding device) the cam-track is formed accordingly.

Upon the front end of the packer-shaft G I packer-shaft G, is the continuously-revolving head L3, having the friction-rollersl Z pivoted at each end thereof. Uponl the dog L2 is formed a projection, Z2, which, when the dog is in the position shown by dotted lines in Fig. 5, is engaged by one of the friction-rollers Z Z, whereby the sprocket-wheel L is rotated. The dog L2 is held in the position shown in the drawings by a projection, l, coming in contact with the end of the tripping-lover M, which pivoted to the bracket M2, fixed to the side board, F. Vhen the binding mechanism is at rest, the tripping-lever M is held down by the spiral spring ym, which is confined upon the bent rod ongby a thumbnut, ym3, the upper end ol the rod 'mi2 beine; pivoied to the tripping-lever M, which now rests on the projecting` curved point of the bracket MQ. The pawlor dog L2 is held in contact with the tripping-lever M by means of the spring Z3, fixed to the sprocket-wheel L. Upon the crank-arm j2 (by which the needlevarm is actuated) is a project-ion nearly at right angles, to which is pivoted the connecting-rod M3, whose lower end is pivoted to the starting-lever M. Formed upon the trip-rod M3, near its upper end, is a curved projection, mt

N is t-he trip-arm, fixed to the trip-shaft n near the center of the binder and immediately under the knetter W. The trip-shaft 'n runs through to the front oi the machine, where it has fixed to it the curved arm N2, in the end of which is a set-screw, n2, whose point rests under the curved projection ymi on the triprod M3.

The mechanism for starting the binder just described is substantially that usually employed; but the arrangement of the, several parts is more particularly referred to, as their disposition differs from that usually resorted to, and their operation is as follows, viz: The grain is packed upon the trip-lever N and against the compressor H by the packers G2 i2 until its weight forces down the trip-lever N to the position shown by dotted lines, Fig. 5, and raises the curved ar-m N2, whose setscrew n? elevates the trip-rod M3 and startinglever M far enough to release the dog L?, which is.immediately forced to the position shown by dotted lines by the spring Z3, thus throwing 'the projection i? far enough outward to catch one oi' the friction-rollers Non its way around, and thus set in motion the sprocket-wheel L, l'rom which the chain` L' runs over the binder sprocket-wheel K and ejector sprocket-wheel P, each ot' which makes one revolution to each bundle bound. pon the binding mechanism being` started, as just described, the arm [2 swings over to the position shown by dotted upper end to the projection on the arm f2, and

when this arm is swung` over to the position shown by dotted lines the connecting-rod M3 raises the starting-lever tothe position shown by dotted lines and holds it in that position until the needle-arm has performed its work `to be bound.

and falls back, when the trip-lever M is allowed to drop down to its original position, the end catching the upwardly-projecting portion of the dog L?, throwing it into the position shown, and releasing the projection Z2 from Contact with thc friction-roller l, which now revolves around outside of it while the binding' mechanism stops. The packer-shaft continues to revolve and the packers to pack the grain upon the trip-lever and against the compressor for the next bundle. The size of the bundles is regulated by the set-screw n2, as usual.

Journaled in the supports F is the ejectorshaft p, having the ejector sprocket-wheel P fixed to its front end. The ejector-shaft p runs through to near the center of the binder, where it has xed to it the ejector-crank p2. Pivoted on one of the supports F is the friction-roller r, which is fitted to a curved slot in the ejector R, whose lower end is pivoted t) the ej ector-crank p2. The ejector sprocketwheel P, being the saine diameter as the binder sprocket-wheel K and driven by the saine chain, necessarily makesonerevolution to each bundle bound, In the drawings the ejector is shown in its position when at rest-il e., while thcpackers are at work accumulating a gavel when a gavel has been formed and the trip-lever has started the-binding mechanism, the ej ector-crank p2 rotates in direction of the arrow and causes the point of the ejector to slowly travel alongl the dotted line from S to S2 during the interval of the movement ofthe needle-arm while encircling the gavcl and wh ile the knotter is 'forming the knot, at which movement the point a; ol the cam-track on the binder sprocket-wheel K has arrived at the friction-roller r2 ol' the cam-lever h3, the cani raises thespring-rod YF and arm ll", the compressor-shaft li rocks. carrying` with it the arm lli, and b v means oi" the link H2 throws down the compressor ll and releases the bound bundle. At the same time the ej eetor commences its upward n'uiwement, and as the leverage from the pin ofr the crank p2 and friction-roller r is very much reduced the motion of the ejector correspondingly accelerated and travels from S2 to Sfi quiekljf, carrying` with it the bound bundle, which is forcibly snatched away from its position, separated from the unbound grain, and thrown out upon the ground, the deflect-or T2 preventing the bundle from rising off the point of the ejector. At this moment, the dist-ance from the pin of the crank p2 and friction-roller r becoming much increased, the ejector returns without shock to its original position, with the point resting at S.

Instead of discharging the bundles upon the ground, as just described,thej7 maybe received in a bundle-carrier, as shown in Fig. l. This device consists of a rock-shaft, t, pivoted in the supports F4, and having the arm t2 fixed to one end thereof, while it is provid ed with curved fingers T T, 'lined at suitable inlOO lIO

tervals for receiving' and retaining several bundles. It is held in the position shown by the rod t3, pivoted to the arm t2, and terminating in a handle in reach of the driver. This rod t3 has formed in it two loops, u, (only one of which is shown,) which are engaged by a pin in the post A2. Vhen a'sufcient number of bundles have been collected in the bundle-carrier, the rod t3 is released from the pin in the post A2 and the load dumped by the turning of the shaft if and consequent dropping of the fingers T T.

In practice it has been found that sometimes the grain may be very sparse over the held and may be turned endwise, in which event it is scattered loosely over the conveying and elevating mechanism, and therefore to move the grain successfully there must be a moving surface upon which the grain is carried forward and upward in order to facilitate its elevation and accumulation for binding. Therefore we employ a conveying-belt, and also elevating-belts--in this case two belts-one on each side of the cord-carrying or needle arm, for the grain to rest upon, While above the grain two similar belts are arranged to still further insure the proper elevation of the grain and its delivery to the packers. By this means we are enabled to convey the grain perfectly, in whatever position it maybe presented, to the elevator-belts and to securely deliver it to the binding mechanism, where it is compacted preparatory to being encircled by the band, the band knotted, the cord severed, and thefbundle discharged by the mechanism herein described.

The elevator-belts V V2 may be constructed as herein described, the lower belt, V2, taking the place of the usual stationary bindin g-deck,

or it may only reach to the needle-arm shaft J; or the partsV may be arranged as shown in Fig. 8. In this case a shaft, v717, is pivoted in the side boards, F `F, and fixed to said shaft are fingers H7.- Upon the front end of the shaft hl may be an arm, to which may be pivoted a rod connecting it with the binding mechanism in such a manner that as soon as the binding mechanism is set oft' or started the shaft f may rotate slightly, raising the ingers HT to the position shown by dotted lines, thus raising the accumulated bundle clear from the elevating-belt V2, in order that the movement of the same may not disturb the free and effectual operation of the binding mechanism. lAfter the bundle is bound t-he fingers Il2 may again drop out of the way until another sheaf is accumulated.

We are aware that it is old to bind grain over an intermittingly-moving carrier, which carrier is, however, during the binding operation at rest. We are also aware that it is old to employ a feed mechanism which gives to the cut grain a step-by-step movement while a sewing device unites it into a sort of gavel. Such earlier devices we disclaim, but believe ourselves to be the'irst to dispense with a binding-deck which is stationary during the operation of the binding mechanism, and to bind directly upon the moving elevating-belts.

Having thus fully described our invention, its construction and operation, and without wishing to be understood as restricting our claims to invention to the precise forms, proportions, or arrangement of the parts, or to the particular device herein described, or to any devices not essential to the principle of construction and mode of operation of the improvements made by us and herein described, what we claim as new, and desire to secure by Letters Patent, is-'- 1. In a self-binding harvester, the combination of a continuously-moving grain-carrier, a bundle-forming mechanism, a needle-arm operated from beneath, and a knotter mechanism situated over said grain-carrier and binding the grain while resting thereon. Y

2. In a grain-binding harvester wherein the binding mechanism is situated between the grain-platform and the drive-wheel, the combination of the inclined continuously-moving elevating-belt, which carries the grain over the drive-wheel, and a knotter mechanism situated over said belt, which binds the grain while resting on said Amoving belt.

3. In a grain-binding harvester, the combination of a continuously-moving elevatingbelt divided substantially centrally and a binding mechanism situated over said belt and adapted to bind the grain into bundles while resting on said belt, parts of said binding mechanism operating` through the space between the parts of said divided belt.
