|MPRovi-:MENT IN HARVESTERS.

Specification forming part of Letters Patent No. [64,799, dated June 22, 1875; application filed May 25, 1874.

To all whom' it may concern:

Be it known that I, HARRY H. BRVIDEN- THALL, Jr., ofLatrobe, in the county of West moreland, in the Sta-te of Pennsylvania, have invented new and useful Improvements in Grain-Binding Harvesters; and I do hereby declare that the following is a full, clear, and exact description thereof', which will venable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure I is a rear view of my improved machine partly in section, the sectional part of which shows the compressing mechanism. Fig. II is a top view ofthe same, showing the general plan of arrangement of the various devices. Fig. III is a side sectional view of the same taken through the line a: :o m, Fig. II,

and showing the operatingmechanism. Figs.`

IV and V are detailed sectional views ofthethroat, and show the manner of forming the band. Figs. VI, VII are sectional'views of the band, showing its arrangement.

Similar letters of reference where they ocy our in different figures denote like parts of the machine in all of the drawings.

The object of myinvent-ion is to improve the construction of grain-binding harvesters, making them more convenient in use and more effectivea in operation, causing' the cut grain to be deposited at such distance from the standing grain as to be out of the way of the machine in its next round and in ga-vcls suitable for handbinding, or substantially l bound in sheaves as may be desired. It consists in a raking device 5 in the arrangement of the forming-hook, whereby the gavels are bound by means of the interlocked hoop system, in .a throat, by which the loops are protected while being formed, and more closely and substantially interlocked 5 andin the-construction, combination, and arrangement of the various parts of the machine, so that the operations of reaping, gaveling,and bindingmay be performed, as hereinafter more fully described, and specifically claimed.

The cutting device to be used in my machine docs not differ from that usually employed in this class of harvesters. y

`A A are the drive-wheels, which are connected to themain axle a in any suitable way. The axle o has its bearing within the sleeve al, which is rigidly attached to the forwardl end of the shaft al. rIhe shaft al is pivoted to the frame B by suitable bearings, in boxes attached to the frameJ B. The bevel-Wheel q? is rigidly connected with the axle a, and meshes with the bevel-pinion a3 upon the shaft a4. The shaft a4 rotates lwithin suitable boxes in the frame B. The bearings of the shafts al and a? are in axial line with each other. the grain-platform, which is, by means of the finger-bar D, rigidly connected with the frame B. By this constructionthe axle a is allowed to oscillate above the main frame B, thereby enabling the machine to move more steadily over the rou gli ground of the field. lThe shaft E revolves within suit-able bearings attached to theinuer'side ofthe platform C, and motion is communicated to it from the shaft c4 by suitable miter-gears and shaft, arranged at the forward partof the frame B and the platform C.

The wheel e fits loosely upon the forward part of the shaft E, which turns therein, ex-

cept when engaged by the clutch el, in order to communicate motion to the shaft I, for purposes hereinafter described. The clutch el is operated by the lever It, which communicates with the shipper-arm r, by means of a short shaft in a suitable box. The' lever B is operated by a pin in the toothed segmental arm J, in such a manner as to connect the clutch el only when there is a gavel in the binder.` e2 is a combined square pinion and miter-wheel, the square part of which meshes with the segmental arm J, and the miter-gear meshes with an idler-miter, e5, which is `pivoted to a stationary stud on the platform C. The idlermiter e5 meshes with the miter c3 upon the shaft E, which turns loosely within the wheels c2 and c3, between which and upon the shaft E is the double clutch c, which can be, by means of the shipper-lever O, made to connect with either c2 or c3, -or be disengaged with both.

By this construction the segmental arm J can be moved backward or forward, as may be desired, and is'held in either extremity of its movement by means of the studded rod P, which is operated as hereinafter described.

The bevel-pinion e6 lits loosely upon the rear Gis' end of t-he shaft- E, and meshes with the bevel-wheel h, which is rigidly connected with the shaft H, which communicates motion to the raking device when the clutch c" is e11- gaged in a manner hereinafter described. The pawl 67 rests within the notch h6 in the wheel h, when the rake is not in operation, thereby holding it in its position. while a sheaf is being' bound, or a gavel gathering upon the platform U. To the inner side of the grain-platform is attached the post T, which supports the bandforming mechanism. To the upper end of the shaft .l is connected the bevel-wheelj", which meshes with a pinion upon the shaft t2, which has its bearing in boxes in the arm t1. Near themiddle of the shaft t2 is an eccentric, which operates the pawl upon the ratchet-wheel t3, giving it an intermittent rotary motion. The said ratchet-wheel in turn rotates its shaft, which communicates motion to the pulley a land the endless spiked bands S- S, and the compressing-belt M, for the purpose of holding and rotating1 the gavel while the band is being formed thereon. The bands S S may he formed of a metal chain, with links suitably provided with prongs or tines. The shaft may be connected with the frame t, so as to be capable of adjustment therein, in order to adjust the tension ofthe bands S S. The endless belt M passes around the pulley n, as in dicated by the arrow, thence around the pulley a, thence through the tightening springblock n, thence down around the pulleys a4, a2, and n3. The tightening-spring U serves to take up the slack of the compressing-belt M when there is no gavel in the binder; also, to enable the machine to bind a large or a small sheaf with equal tension. In place of the spring U there may be substituted a weight or a spring' coiled within a drum, with a cord or chain to wrap around the same, for the purpose of operating the pulley-block o16. The

toothed segmental arm J is secured within suitable bearings, so as to be capable of moving in its own arc, and carries the pulley a3 at its outer end, around which is the guard or hood o4, for the purpose of assisting in gathering' the grain into the binder, and to keep the belt M upon the said pulley a3. The toothed segmental arm J has for its purpose to'carry the compressing-belt M around the gavel to hold it against the bands S S, for the purpose before mentioned.

To the outer end of the shaft t2 is secured the crank-wheel t7, which, by means of the connecting-rod t4, gives the rod q a reciprocating motion corresponding with the intermittent motion of the belts S S. The said rod q is connected by means of suitable boxes, rigidly connected to the frame T1. To the lower end of the said rod q is pivoted the band-formng\hook T. One arm of the said hook eX- tends upward to the slot t5 in the frame T1, where it is provided with a pin or frictionroller, which plays within the said slot t5, which is provided with spring-ledges, which guide the pin in its vertical motion, so as to pass upwardA along the left-hand slot, and downward along the right-hand slot, thereby giving the forming-hook a lateral oscillating motion, while being driven with a vertical reciprocating motion, for the purpose of drawing the loops from the gavel and stretching or drawing the said loops forward in order to allow the forming-hook to pass through the last one formed, and draw the next one through it without tearing the said loop. The lower end of the rod q serves as gate or cast-off to throw the loops over the forming-hook. By this construction the forward or that part of the forming-hook which bears against the loop is nearly or altogether in line with the plane of its longitudinal motion, thereby, in a measure, preventing the loop from being torn or cut by the friction produced by the reciprocating movement of the said forminghook, as in the ordinary construction,wherein an inclined plane impinges against the loop, drawing forward and stretching the loops or bands. The forming-hook T and the rod q are placed at angles with the frame T1, so as to reciprocate and draw the loops obliquely to the radius line of the gavel,'thereby allowing the hook to pass farther into the gavel to draw the loops therefrom, and, in a measure, obviating the liability of the loops being entangled in the center of the sheaf, as in the ordinary construction, wherein the tufts or loops are drawn radially from the center of the sheaf. By this construction and-arrangement the sheaves are more easy to open for thrashing, and a more substantial band formed by giving the loops a better hold within the sheaf, and by overlapping the loops with a sharper angle, as shown in Fig. VL To the under side of the frame Tl is secured the throat-plate e, which is constructed so as to form the cheeks v6 and o6, which are rounded on the inner and under side edges in such a manner as not to cut the loops as they are drawn upward through, as shown in Fig. IV. Friction-rollers may be vadvantageously used, suitably pivoted to the lower inner edges ot' the plate o. The cap @l is connected with the upper side of the plate o, by" means of the ledges o3 and c4, in such a manner as to be adjustablev in relation to the hook T, and the plate fv. Under the said cap o1 is the slide o2, which fits loosely within its place, and is held to the right-hand extremity of its movement, and against the hook T, by means of the spring o5. The slides ol and o2, being arched form a cavity under them, and above the cheeks o6, as shown in Fig. IV.

The plate e and the cap o* may be formed in one piece, and dispensing with the slide 02, by making the plate o adjustable upon the frame t1. The plate c may also be grooved so as to let the endless belts S S operate within the grooves, and their lower edges come Hush with the under surface of the said plate c. From the rear edge of the platform C projects a short bracket, to which is secured the post or rod k1, about which rotates the sleeve k2.

glcagree `3 ing, in which works the rod ki", the top of which is bent, forming the cranks k1", which .are similar to the stationary cranks ku. `At fthe top of the rod k1 the said 'cranks 7cm and cllare connected by the-slats k6 and k7. The

lrod 165 :is curved forward and downward, the` lower end of which terminates in a shaft running backward and parallel with the surface of the grain-platform C. By this construction the rodk5 is carried by the arm 194 around the post k1 as a common center, and the straight part of the rod h5 always points in the same direction in relation to the platform G. The rake-board K is secured to the straight part of the rod kf by means of the sleevek, which has suitable ears for its secure attachment to .the rake-board K. The llDDer edge of the said board is secured by means of the guard k, thereby allowing the rake-board to move a short distance backward and forward along the straight part of the rod ki", and is held in the forward extremity of its `movement by means of the spring k. To the lower rear corner of the rake-board K is secured thevfriction roller ki', which has for its purpose to prevent the rake-board K from passing too far forward bystriking against and rolling along the rear edge of the platform C while the rake is sweeping the grain to the inner side of the platform. The exible rod :r3 is securely connected to theA upper forward corner of the rake-board K, and projects for Ward and is curved downward nearly to the platform, and has for its object to assist in gatheringthe grain into the binder, and enabling the segmental arm J `to encircle the gavel by passing between the vertical `part of they rod .r3 and the end of the rake-board K. The rod x3. being elastic enables itto extricate itself, when entangled with other portions of the machine, without injury. y

To the outer end of the arm k4 is secured the short curved arm w1, which has for its purpose to move the rake-board backward for the purpose of allowing the rod .r3 to pass the sleeve k2, while the rake is passing rearward from the inner to outer side of the grainplatform, by pressing against the frictionroller a3, which revolves about a stud connected with the top of the rake-board K, ina manner as hereinafter described. The arm 7a4 and the slats cand k7 are made `suiiiciently Awide so as to overlap each other a little when their respective cranks are at right angles with them, for the purposefof1 preventing stalks of grain from getting between. t

The operations of my machine are as follows: Suflicient grain having accumulated upon the grain-platform C to form a sheaf, the operator pushes thelever `L slowly forward. The studilupon the end of the` arm i slips down the inclined ledge Z3. The lower end of the lever L being pivoted to the shipper-lever Z4. thereby moving the pawl Z7 upon the arm l1 of the shipper-lever l4 out of theI notch h6 in the wheel h, further movement of the lever L engages the clutch e7, and thus communicating motion to the rake. The stud l1 slips a little way under the end of the inclined ledge Z3, thus holding the lever L in its position. The clutch e7 is held in gear by the pawl Z7, which rests against the rim of the wheel 7L. The rake moves rearward around to the outer side of the platform, thence across, sweeping the gavel over the pulleys n2 and n3, :and upon the compressing-belt M. The bevel-wheel h and the rake having made one revolution, the pawl Z7 is` forced into the notch h by the spring ls, thereby releasing the clutch c7 and retaining the wheel h and the rake securely in position against the gavel, where it remains during the operation of binding, and preventing the falling grain from being entangled with the revolving sl'reaf. The pawl Z7, in moving intoA the notch h3, throws the lower end ofthe lever L, with the connecting-rod N, forward, thereby carrying the stud l1 past the lower'end of the ledge Z3. At the same time, by means of the connecting-rod N, oscillates the shipper-leverV O upon its fulcrum 0, withdrawing a stud upon the rod P from the notch jl, Fig. I, and moving the clutch e4 so as to engage the wheel c2, thereby operating the segmental arm J, so as to carry the belt M around the gavel rising and holding it against the spiked bands S S. The arm J having nearly completed its movement, the pin si strikes the end of the arm 01, depressing it, thereby bringing the shipper-lever ,O to its first position, moving" the stud upon the rod l? into the notch .7'2 in the arm J, and releasing the clutch e4, thereby retaining the arm J in its position; also holding the gavel encircled by Vthe belt M and spiked bands S S.` The lever- R being now depressed, as before described, motion is communicated to the band-forming mechanism,` which operates as follows: The forming-hook T strikes into the gavel, and, in so doing, thepin or stud t passes to-and down the right-hand slot, thereby opening laterally the honk T, which returns a little way open, or in the same lateral position, before closing, for the purpose of filling the said hook with straw. The hook closes by the pin t6 passing across to the left-hand slot, and passes upward, drawing the tuft with it `through the .throat v, forming a loop. The

pawl s4 now acts upon the ratchet-wheel t3, and moves the bands S S so as to rotate the gavel a little to the right as the forming-hook com- Imences its descent, when the point of the hookproper just passes the edge of the slide M02. `The pin t6 passes across to the right-hand slot, thereby oscillating the hook T upon its fulcrum S5, thereby carrying the band to the `left, stretching the loop and placing it beneath` the slider2 and upon the plate t. The

y hook. passes through, and, being tapered side- -wise, spreads the loop, forcing it into the cavity t3, as shown in Fig. 1V, where it remains protected from being injured by drawing the next loop through it. The hook having again filled itself, as before described, draws the tnft through the throat and the previouslyformed hoop, when the pawl s3 again acts upon the ratchet t3, and again moves the gavel to the right, carrying the first-formed loop out of the cavity t3. The downward movement of the forming-hook places the second loop within the cavity in the same manner as the rst, then, passing into the gavel and taking up another, and drawing it through the second, and so on, repeating the operation until a band of loops is formed. The first of the` series coming under the hook, the last are drawn through them, thus connecting the first and last, and forming an endless band of interlocked loops.

The part of the pulley n carryin g the belt M is somewhat larger than the parts carrying the bands S S. By this construction the slack or difference of circumference of the gavel, caused by the shrinking of the sheaf while being rotated and bound, is taken up just before coming under the bands S S. The gavel is therefore being compressed during nearly the whole ofthe binding operation. 1t will be seen that the compressing-belt M passes directly over the series of loops as they are formed, compressing them and insuring their coming fairly under the hook for the purpose described. The binding of the sheaf being com-l pleted, the operator draws the lever L backward, and, by so doing, the stud Z1 passes over the inclined ledge Z3, and the connecting-rod N oscillates the shipper-lever 0, so as to push the stud upon the rod P out ot' the notch jf, thereby releasing the segmental arm J. The lower end of the lever 0 moves the clutch c4 so as to connect the wheel c3, thereby reversing or withdrawing the arm J, which, when withdrawn nearly far enough, the pin s strikes against the arm o1, thereby releasing the clutch et, and drawing the stud upon the rod P into the notch j', and holding the arm J in position. T he-upper` end of the lever R being now raised by the segmental arm J the clutch c1 is released, and the binding mechanism stops. The tightener U takes up the slack of the belt M, causing it to throw the sheaf against the rake-board K, where it remains until another gavel is to be bound. Sudicient grain having accumulated upon the platform for a sheat', the operator pushes the lever L forward, as before described, throwing the pawl C7 out of the notch h in the wheel p and starting the rake, which moves backward, throwing the sheaf off the platform. During the backward movement of the rake-board the arm m1 presses against the friction-roller x2, thereby moving the rake-board rearwardv along the straight part of the rod h5, for the purpose of allowing the rod x3 to pass behind the sleeve 7a2, when the end of the arm xl slips past the roller x2, and the spring kf moves the rakeboard forward, and the operation of raking and binding a sheaf is repeated.

When the gavels are to be deposited upon the ground for hand-binding, the frame T1, arm J, belt M, shaft I, and the shipper-lever 0, with their necessary connections, are removed, and the mesh of the miter-gear wheels h1 and h3 are changed, so that when the pawl 17 rests within the notch h the rakeboard will be in aposition at the outer side ofthe grain-platform to deli-ver a gavel. The operator moves the lever L forward, as before described, releasing the wheel h, and engaging the clutch el, thereby starting the rake, which sweeps the grain across to the inner side ofthe platform and against the board L1, when the backward movement Vof the rake draws the gavel oi the platform and passes round to the outer side of the platform, when the pawl drops into the notch h6, vas before described.

- When the machine is to be used as a mower, the whole of the plat-form (l, with its necessary connections, are to be removed. The height. of the stubble may be regulated by means of any suitable arrangement which will enable the tongue to be adjusted to different angles relative to the main frame, so as to tilt it forward to lower the cut, and tilt it backward to raise the cut.
