signor to the St. Paul Harvester Works, St. Paul, Minn. Original No. 177,231, dated May 9, 1876. Filed June 12, 1879.

To all whom it may concer-n:

Be it known that I, JOHN H. ELWARD, of Stillwater, in the county of Washington and State of Minnesota, have invented certain new and useful Improvements in Harvesters; and I do hereby declare that the following is a full, clear, and exact description of the invention, that will enable others skilled in the art to which it appertains to make and use the same, reference being,r had to the accompan yin g drawings, and to the letters of reference marked thereon, which form a part of this specification.

Figure 1 is a perspective view of a harvesting-machine embracing my improvements. Fig. 2 is a transverse vertical section through the same, and Figs. 3' and 4 are detached views of parts of the machine hereinafter described.

Similar letters of reference denote corresponding parts wherever used.

My invention relates, first, to a novel arrangement of means for effecting the desired adjustments of the reel 5 second, to a novel arrangement of delivery-chute in connection with the grain-receiver and dumping-tray; third, to means for determining the position of the gavel relative to the bundling devices; fourth, to the bundling devices themselves; and, lastly, to certain details hereinafter fully described.

The machine in its general organization is similar to many now iu use, and it need therefore be described only so far as is necessary to an understanding of my improvements.

In the accompanying drawings, A represents the gear-plank or main longitudinal bar of the main frame, upon which the drivinggearing of the machine is mounted in a manner described in a former application. rlhis gear-plank is located upon the grain side of the drive-wheel, and has its' forward end slotted or bifurcated, as shown in Fig. 1, and within the slot thus formed one of the tongue or pole straps a t is placed, the other strap being placedat the side of thepole-plank. The two straps thus clasping one of the arms of the gear-plank snugly between them and being pivoted thereto at their rear ends by a through-bolt, lateral relative play ofthe main frame and tongue is effeetually prevented, thus giving great steadiness to the movement of the machine without interfering with its vertical adjustment.

B is the seat-plank, supported above the inclined elevator or inner end of the platformcarrier by transverse bars arranged in front andin rearof the elevatorin a well-known way, and about midway of the length of this seathar is secured an upright, to which the inner reel-bearer, b, is pivoted at or near or slightly in rear of its center. b' is the outer reel-bearer, pivoted in a similar manner and in the same transverse line in a frame or support, b2, secured to the rear outer corner ofthe platformframe, as shown in Fig. 2. The rear ends of these reel-bearers are connected by links c with crank-arms c' on a transverse rock-shaft, e2, mounted in suitable bearings at the rear of the platform-frame, the arrangement being such that when any vibration is imparted to one of the reel-bearers a corresponding movement is imparted through the rock-shaft and links to the other bearer, thus sin'iultaneously adjusting both ends of the reel-shaft sup ported upon the forward ends of said bearers.

Upon the forward end of the seat-plank B is mounted a bell-crank lever, d, connected by a link, d', with the forward arm of the reelbearer b, by means of which the reel-bearers can be adjusted by the driver at will, a rack at dx and any usual form of thumb-latch serving to hold the lever at any desired adjustment.

The reel-shaft has itsY bearings in sliding boxes e o, placed on the forward ends of the bearers I; b, and these boxes are connected by links e' e with crank-arms on a rock-shaft, e2, which, iu this instance, serves as the pivotal center of the reel-bearers. The inner end of this rock-shaft is provided with a lever, el, by vibrating which the reel-shaft can be moved forward or backward at the will of the driver, as the nature of the work may require, a rack, e4, serving to hold the lever at any desired adjustment.

To accommodate the adjustments ofthe reel, as described, the rcel is connected at its inner end, by atumbling-joint, with an extensible shaft, ff', which, at its opposite end, is con-r nected by a similar joint with a driving-shaft, f2, mounted in fixed bearings y g, attached to. the front of the elevator-frame, in such relation thereto as to be about in line with the reel-shaft in its usual or more frequent position, and around an extension of which line the reelis adjusted. By this arrangement the reel can be driven with equal facility under any adjustment, while the shaft f2, being unaffected by these adjustments, may be driven by any usual or preferred arrangement of gea-ring or driving belts or chains connecting it with the driving-wheel.

The platform apron or carrier and the elevator-apron are made in any usual or preferred form, except that I prefer to connect the aprons and the slats thereon with an endless drivingchain placed inside of the endless apron, and about midway of its width from front to rear, and traveling upon sprocket-wheels or grooves on the apron-rollers midway of their length. By this arrangement the strain or tension and wear upon the apron is in a great measure avoided, while at the same time the tendency ofthe apron to at its center is obviated.

The inclined delivery-board E, down which the grain passes from the elevator to the binders grain-receiver, and said receiver itself, except in particulars hereinafter recited, may be of any usual or preferred construction.

To the end boards of the elevator-frame, or to blocks F, connected therewith, are hinged by their upper ends two gaveling-boards, F', one at the front and the other at the rear of the delivery-board E. The board E is provided at each end, near its lower edge, with a series of perfbrations, at t, arranged in the arcs of circles, of which the hinges to the boards F' are the centeis, and the lower edges of the boards lf' have each a pin, which may be placed in any one of its respective series of holes, for adjusting` the angle of the boards, and thus giving' direction to the movement of the descending grain for placing the gavel tartiner forward or farther back, as described.

The main frame, at its stubble side, has an upright frame, (indicated at a?, Fig. 2,) a3 representing a longitudinal bar, and the binders stand or platform H, on its adjacent side, has a similar upright framing and longitudinal v bar a, and these bars a3 a', about midway of their length, are connected by a horizontal pivot, g', upon which the binders-platform fraijne is suspended, and upon which, also, it is adapted to be swung orvibrated for the purpose of maintaining its horizontal position Linder the different adjustments of the main frame.

The forward cud of the biinlersplatfoi'm frame is connected by alink, h, with the rockshaft h', through which, by means of a lever, h2, the driver adjusts the height of the cutting apparatus, the arrangement heilig' such that as the main frame is vibrated for changing the height of the cutters the binders7 platform is correspondingly vibrated relative thereto for preserving its horizontality.

G is the grain-receiver, consisting of a pivoted longitudinal rod provided with a series of horizontal fingers adapted to receive and hold the grain to be bound. Just under this receiver is located the inner side of the binderstable frame, H', composed of a series of longitudinal bars connected by transverse bars, and forming a slotted rectangular table, open centrally at H2, to accommodate the binders standing on the binders7 platform H. This table is hinged at its outer edge to the upright platform-frame, and has its outer edge supported by hinged feet hx, resting in sockets on the platform H, adapting it to be folded out of the way when not in use.

The platform H has a vertical rim extending around it, giving it the form of a shallow box or receptacle for heads and loose grain that may become separated in the process of binding, Svc., and the table-frame is provided at its ends which project beyond the platform with end boards, k, to which boards It" are hinged by their upper edges, and said boards, inclining inward, as shown, have their lower ends located within this shattered-grain receptacle, for insuring' the deposit of the loose or shattered grain therein.

The platform H has arms l l projecting from its outer side, in the outer ends of which the longitudinal pivot of the bundle carrier and dumper L has its bearings, said dumping-carrier being arranged about in the same horizontal plane with the upper edge of the rim of the platform H, as shown.

K is an inclined or concave chtite, extending between the elevated binders receptacle and the inner edge of the bundle-carrier, as shown, the arrangement being such that when the bound bundles are released at the outer edge ofthe receptacle G they are automatically conveyed to and deposited upon the bundlecarrier. The chute K is, by preference, made of the inclined curved bars or slats arranged between the binders; but it may be in a single wide piece, if desired.

A cord, l', extends from the inner edge of the dumpin g-carrier L, through suitable guides, to the drivers seat, for enabling the driver to dump said carrier whenever it is desired.

Upon the slatted table H is placed a removable bundling attachment, constructed as follows, viz: At or near each end of said binders7 table is an upright triangular frame, N, the lower or horizontal bar of which rests `on the slats of the table, and has a button which, when turned longitudinally, passes between and below the slats, when, being turned transversely, it engages with the slats and fastens the end frames, N, thereto.

The outer inclined bars, N', of the framesN extend beyond the apex of the frames, and are united at their upper ends by ahorizontal bar, NZ, and at or near said apex said frames are further united by a horizontal shaft, O, to which motion is imparted by a cone-pulley or I sprocket-wheel, P, mounted loosely on its forward end, and connected therewith as follows: The forward end of the shaft O has a crosshead, o', rigidly connected with it, (see Fig. 3,) and directly in rear of said cross-head the shaft has an eccentric, 02, formed upon it, which forms the journal for the cone-wheel P.

The forward face of the cone-wheel has a pin or spur, p, formed upon it near its periphery, and as the wheel is rotated the pin strikes one of the arms of the cross-head o', and through said arm imparts a rotary movement to the shaft until, by the eccentric relation of the wheel to the cross-head, the pin p moves outward sufficiently far to escape from the one arm of the cross-head, leaving the opposite arm in position to be acted upon by the pin in its turn. By this arrangement an intermitting movement is imparted to the shaft 0, and it is allowed to remain stationary during just one-half the revolution of the wheel P, for a purpose which .will be hereinafter explained.

The speed of the shaft O is regulated by the cone-pulleys, upon any one of the series of which the driving band or chain may operate, according to the necessities of the Work, said chains being driven from one of a corresponding series of cone-pulleys, (indicated bydotted lilies at P', Fig. 1,) the shaft of the latter series of coilepulleys being connected through bevel-wheels with a transverse shaft, f3, which, in turn, is connected by a tumbling extensible shaft, f4, with the shaft f 2, which drives the reel. By this arrangement I provide for the driving of the shaft 0 under all the varying relations of the swinging binders platform and tables to the main frame.

Upon the shaft 0,'about midwayofits length, is secured a cross arm or arms, Q, made preferably in the curved or S form shown, connected centrally to the shaft, and provided at its ends with horizontal pins or studs, on which are mounted smal] groovcd rollers g, fora purpose which will bc explained.

The upper bar, N2, of the bundling-frame is provided with suitable bearing-brackets, in which is mounted a rock-shaft, r, the rear end of which is provided with a curved angular arm, r, the outer swinging end of which overhangs and extends downward in close proximity with the outer edge of the binders7 grainreceptacle G, as shown. A cord, '8, is connected at one end with the swinging end of arm i", and, extending up through the plane of the circle in which the grooved rollers gare carried by the arm Q, and through a guidingeye in the bar N2, has its upper end connected with a spring, t, connected to the frame N or frame-bar N2, as shown, said spring serving at all times to hold the cord s taut.

The forward end of rock-shaft r has an arm, r2, attached, which extends down sufficiently far to engage with one of two arms or stops, o4 o4, on the shaft 0, and which serves, when a bundle is in position and compressed, as hereinafter explained, to hold the arm r with its cord in proper position for holding the bundle.

The shaft O, in rear of the forward frame, N, is provided with a cam or ratchet disk, u, (see Fig. 3,) and a pawl, u', pivoted to the frame N, engages with said ratchet-disk and prevents the backward rotation of the shaft O when the cross-head 0 is released from the pin Vp on its d rivingwheel l).

There the bundling attachment above described is used concave composed of two or more parallel bars, V, is arranged above and rests upon the ordinary grain receiver, as shown, or it may be in the form of a slotted concave, in which the grain discharged bythe elevator is deposited, V representing the slot in which the bundling-arms Q move for gathering and compressing the grain.

The operation of these devices is as follows: Supposing a sufficient quantity of grain to be in thc concave V to form a bundle, a half-revolution is imparted to the shaft() by the wheel P through the connections described, imparting a continuous movement to the cross-head or bundling-arms Q. The groove-d pulleys on the upper arm strike against the cord s, and pressing it before it carries it over and behind the grain in the concave down through the slot Vl and urnlerneath the grain until the arm Q comes close to the arm r', to which one end of said cord is attached, thereby forming a loop (see dotted line at s) in the cord s, encircling or nearly encircling the bundle. When the arm Q orQhas reached this position the stops o4 and u u come into play, as described, and hold the arms Q and r while another gavel accumulates behind the arm Q', giving the operator ample time to apply the band. During this operation, it will be seen, the bundle is tightly com pressed by the cord s, which is held under tension by the spring t, the bundle being thus completed by the time the wheel P has completed its half-revolution necessary to again connect it with the shaft 0, as has been explained, when, by further movement of said shaft, the arm i" is released, and the cord sis retracted into its former right line, releasing the bundle, which is crowded outward by the following arm Q, and descends over the chute K upon the dumpingcarrier, when the opera tion is repeated, as before.

By the arrangement of adjustable shields in connection with the grain-receptacle, as described, the attendant is enabled to regulate with precision the delivery of the grain relativc to the bundling or binding devices or to the position of the binders. Thus, where the bundling devices described in another application are employed and the machine is operating upon short grain, in order to deposit it in the receptacle with thc center of its length of strawin the same transverse plane with said bundling devices, it is desirable to swing the lowerend of the forward shields backward, in order to move the grain backward in its de scent into the proper relation to said devices, and to prevent its being carried too far the rear shield may be swung forward and secured at the desired point. When the straw is long the shields will be correspondingly moved outward or away from each other in order to deposit thc grain in the proper relation to the binders or to the bundling' or binding devices.

It is well known that it is practically indispensable that the band should be placed very near the center of the gavel, and it will also be readily seen that it is very desirable that in machines of this class there should be some provision by which thebutt-ends of the straw shall be evened, and shall also be delivered at such point relative to that part of the mechanism at which the band is passed around the gavel that such band shall be placed near the center of the bundle. Ihese results are secured in my construction, and the capabilities and usefulness of the machine are greatly' increased thereby.

It will also be seen that the gavel boards are supported upon the machine independently of the chute or delivery-board or the grain-receiver-that is to say, the lower edge of the gavel-board is arranged above the upper face of the chute-board, and is not permanently atached to said chute, for which reason the chute or receiver can be moved below the gavel-board should such operation be found desirable.

I do not claim to be the first to construct a harvester with a board arranged at the end of the chute or delivery-board, as the patent to Renwick and Watson, dated December 6, 1853, shows boards at both ends of their chute; butin their construction such boards were employed as a part of the frame-work of the machine, and they certainly' did not employ them to guide the grain to the desired point during its passage over the chute, because their drawing shows the grain having its butts and tips some distance removed from the boards; and. further, because they state exA plicitly that they propose to regulate the delivery of the grain over the chute by shifting the position of the upper end of the elevator.

I do not claim, broadly, a vertical board arranged at the end of the chute or deliveryboard, irrespective of its relation to the other parts of the machine or of its function.

It is also apparent that some of the advantages growing out of the use of these shields in machines which can be tilted forward (in order to cut short or iodged grain) may be had without adjusting them or moving their lower ends inward, from the fact that, even though the lower ends remain stationary, the shields will still prevent the short grain or tangled grain from sliding off at the front end of the grain receiver or becoming entangled with the driving-chains or other mechanism which is arranged near the end of the grainreceiver or the delivery-board.

W W represent band-trays for carrying either prepared bands or straw suitable for bands. These are provided with suitablelugs or ears w, adapting them to be readily attached to or disengaged from the table H or frames N, either or both, as preferred. Additional bands or straw therefor may be carried underneath the chute K and at the ends of the binders platform and shatteredgrain receptacle.

When the bundling attachment described is removed, the dumping-table may be raised to the plane-of the tables H-its usual position and under its usual arrangement-if preferred.

The slats of the elevator-apron, to prevent them from lagging or being deflected backward in passing over the rollers, have little angular brace-straps x connected to them at their ends, the feet of which rest upon the apron in rea-r of the slats, and so hold them up to their work. Or, instead of these, if preferred, leather or other yielding straps may be made to hold the slats by being connected therewith and with the apron in advance of the slats.
