SPECIFICATION forming part of Letters Patent No.` 339,561` dated April 6, 1886. Application filed March 16, 1,881. Serial No. 23,409. (No model.)

Be it known that I, SYLvANUs D. LooKE,

of Hoosick Falls, in the county of Rensselaer and State of New York, have invented certain new and useful Improvements in Harvesters,

of which the following is a specification.

My invention relates,mainly,to that class of harvesting-machines in which the grain, after being eut or laid upon the platform, is'carried sidewise by raking apparatus up over an elevator, as in the well-known Marshtype,

' and delivered to a binding-table or to an' au-` tomatic binder or dropped upon the ground;

and for the purpose of properly illustrating the Various features I have represented them in connection with a machine of such-construction.

My improvements consist in a raking mechanism composed of rotating spirals braced by exterior supports; in the combination,with ro-l tating raking spirals braced by exterior supports, of independentinternal supports; in the combination, with an elevator composed of rotating spirals, of a series of rotating star-j wheels, to insure the proper delivery of grain.

from the rake thereto; in a spring-supported iioat overlying the elevator and sustained in a peculiar manner, and in other combinations and details of construction hereinafter described. 1

In the drawings, Figure l is a perspective view of a machine embodying my improvements. Fig. 2 is a top plan view; Fig. 3, a vertical section through the elevator longitudinally of the machine; Fig. 4, details ofthe float and forcing-wheel at the junction of the platform and elevator-lakes; Fig. 5, a detail of the gearing by which the elevator-rake is driven; Fig. 6, enlarged plan view of the outer end of the platform, with parts removed to show therake-gearing; Fig. 7, a vertical section through the platform on the line yy, Fig. 2; Fig. 8, a detail of the gearing which drives the platformirake, and Fig. 9 a detail of the porting-Wheels, B and B', the former of which carries the principal weight-of the machine and serves as the 'driving-wheel .from which motion is transmitted to the operating parts of the machine and the latter being the grainwheel', and a strong frame supporting the apparatus on the axle of the drive-wheel.

For the purpose of varying the height of 6o cut, the machine'is vertically adjustable upon .the axle of the main or driving Wheel, as is The seat C is for the purposes of the pres-` ent description shown as mounted upon the rearwardly-projecting beam C', which runs longitudinally beneath the elevator-frame, the standard c of said seat being seated in a casting, c, which is adjustable forward and backwardupon the beam, and is held at any desired adjustment by means of a bolt passing through the step or casting and through one of a series of holes'in the beam.` The step is vformed with an inclined socket to receive the seat-standard, and wit-h a foot-rest,'c2, to receive the feet of the driver. The standard may be bolted in thesocket, but ordinarily its leverage will be sufficient to confine it therein, and for the purpose of staying it when so confined,and to permitv its kready removal or adjustment,a rod, c3, is provided, having its inner end bent to hook into an eye or staple on the frame of the machine, and having a series of perforations at its outer end to re ceive a hook or pin on the seat-standard, bent at such angle that after the rod has been applied thereto aud hooked into its eye 011 the frame it cannot be removed Without first releasing it from said eye.

In ord er to brace the overhanging rear end IOO i of the beam C, and also to provide aguideor keeper for the driving-chain, as will hereinafter appear, I make use of an angular bracket, c4, bolted by one foot to the rear sill of the frame and by the other to said beam.

The draft-tongue D is hinged or jointed to the sills of the elevator-frame, as usual, and is connected at a suitable distance from the said joint by a link, d, with one arm of an elbowlever, d', the other arm of which is coupled by a ball-and-socke't o r equivalent joint to the forward end of a rod or shaft, d2, which is threaded at its rear end, passes through an internally-threaded arm, d3, and is provided within reach of the drivers seat with a crank, d, or a hand-wheel,by which toy turn it. The rotation of the rod or shaft causes it to move forward or backward, thereby rocking the elbow-lever uponits pivot and causing it to elevate or depress the link, and through it the tongue, according to the direction in which the rod or 'shaft turns. A reel is also employed, which may be summarily described as consisting of a hub, E, attached to the usual reel-.shaft and carrying diagonal braces e and radial hangers e', which -support the outer andinner ends,respectively, of beaters e, extending practically from end to end of the cutterbar.

E E' represent two uprights'or standards at the front of the elevator, bearing near their tops, rmly bolted, two segmental racks, g'and g', between and through which extends a hori-V zontal rod or shaft, g2.

Upon this rod is mounted a yoke, G, having pivoted or jointed to its upper ends a flame or arms, G, supporting the reelshaft, as shown. The yoke is furnished with a hand-lever, g3, by which it may be rocked upon the rod or shaft g2 in order to throw its upper end outward or inward, vand thereby throw the reelshaft forward or j draw it back, causing the reel to stand in ad- Vance or in rear of the cutter or at any interi mediate point. The lever has a locking-dog to engage with the rack g, for the purpose of holding the yoke in its adjusted position, which dog is connected by a rod or wire witha hand-piece alongside the hand-hold of the lever, that may be grasped and operated to disengage the dog in the act of seizing the lever. l

For the purpose of varying the elevation of the reel a second lever, 9*, is pivoted upon the rod -or shaft g2, with its forward end extend` ing some distance in advance of the yoke G, and there connected by a link or rod, g5, with both of the reel-supportingarms G', as more clearly shown in Fig. 1, so that by rocking said lever upon its pivot the link is moved up or down, carrying the arms G with it, the arms swinging on the rod by which they are jointed to the yoke. This last lever is furnished with a locking-dog in the same manner as the other, to engage with rack g and hold the lever and and reel when adjusted. The two levers ex- 1 tend backward, so as'to bring their hand-holds within easy reach of the driver.

The reel-shaft is connected by abar, F, and

tered on the driving-wheel axle, and carrying at its outer end a double chain-wheel, f', andl motion is transmitted by means of a chain-belt from a chain-wheel on the driving-axle to the wheel f, and thence to a wheel on the reelshaft. A single chain-belt may, however, be used by making the usual provisions therefor.

The mechanism relating to the support and adjustment of the seat, that relating to the adjustment of the draft-tongue and its co-operation with the seat, and that relating to the individual adjustment of the reel, as well as the specific construction of said reel, are made the subject-matters of applications filed as divisions of the present, and entitled Division B, relating especially to the seat, filed January 28,.1886, Serial No. 190,046; Division C, relating to the draft-tongue, filed on the same date, Serial No. 190,045, and Division D, relating especially to the reel, also filed on said date, Serial No. 190,074, and to these respective divisions reference may be made for more extended and particular description of said devices, their constituent mechanism, and their purposes.

Hitherto it has been customary to employ dividing-boards inclined in relation to theline of advance of t-he machine, or curved at the outer end, for the purpose of more effectively gathering and drawing in leaning grain. It is, however, found in practice that such construction is objectionable, as the ends of the reel-beaters have to be shortened or kept back to avoid coming in contact with the dividers, and the grain is thereby frequently permitted to escape, and is in consequence bent or broken down and swept under the machine withoutbeing cut by the knife or sickle. To overcome this difficulty, and to insure a clean division and certainty of reeling the grain into the cutters, I employ straight inside and outside dividing-boards, H H', especially the latter. The former may have the usual inclination, extend-ing directly forward in the direction in whichthe machine advances, so that the reel-beaters may sink and move between them in lines parallel with their faces. Wings or flanges h project inwardly along the feet of these dividing-boards, so as to lift the grain away from contact with their walls, and the ends of the reel-beaters project beyond and sweep close over these flanges as they pass back in their beating movement. This construction requires less draft-power than the old, insures less waste, a much cleaner stubble, and otherwise gives very beneficial results.

The raking mechanism by which the cut grain is carried sidewise over the platform,

to insure a f reeand unobstructed delivery.

To this extent the raking mechanism is essentially the same as that for which Letters Patent were granted to myself and Egbert Bowhay, bearing date April 29,1879, and numbered 214,929, upon which this is an improvement.

The platform is formed with longitudinal concave channels t', conforming nearly to the periphery of the spirals. These channels revceive the spirals, and, being oflike curvature in cross-section, serve both to support and keep them in shape and to prevent their mov-v ing out of place. In order the more certainly to retain the spirals inthe channels and prevent their rising, I apply internal bars, fi', the lower face of said bars being rounded to correspond to the internal curvature of the spirals. v To provide against the grain being car-` ried to or from the cutter by the rotation of the spirals, the latter are coiled alternately in right and left hand directions and geared to rotate in a corresponding manner, as before.

In Fig. 6 the gearing by which the raking mechanism is driven is represented, and in Fig. ,8 the construction of parts and the arrangement of gearing is shown enlarged and in detail.

K represents a supporting-block, which is bolted to the frame at the end of the platform, and is provided at its outer end with a spin- Ydle, k, which forms an axle for the Apinion o r head It" of the spiral I, the endof which is seated and secured in a socket in a lug, k2, formed on said pinion. The block is also formed with a transverse hole or bearing to receive the driving-shaft b5, carrying the series of driving-pinions a3, the end and side v faces of the block serving as bearing-surfaces for the pinions, as indicated. Outside of the pinion 7c', and upon the spindle lr, is pinned or otherwise iirmly secured a block, k3, flanged at its sides and adapted to receive and support the end of the bar. or internal brace, i', which is secured thereto by a bolt or equivalent fastening, as shown. In this way the block k3 is very firmly supported, and is at the vsame time made to hold the pinion in place upon the spindle.

The driving-shaft b5 extends across the end of the platform from the forward spiral slightly to the rear of the'platfornnwhere it is furnished with a sprocket-wheel, by which it is driven, and its whole length within the platform, and with it the gearing, which it immediately supports and drives, is coveredl by a cap, a, suitably beveled, to deflect the grain uponV the raking or conveying mechanism, and hinged that it may be thrown back to give access to said gearing to permit oiling or repairs. From the raking mechanism the grain is delivered to the lower end of the elevator, which is of a construction similar to that of the platform-raking mechanism, consisting of a series of spirals, I', with internal bars, ix, as in said rake.

carrying the driving-pinions a, which impart motion to the pinions Z of the spirals, rotating about the spindles Z of the block, and held in place thereon by the block Z2, to which are secured the bars tx. The shaft b4, like its companion -shaft at the outer end of the platform, 4is providedlwith a sprocket-wheel atk the rear of the machine, whereby it may be driven, and with its immediate gearing iscovered or incased by a hinged cap, c', which also forms a bridge between the platform and elevatorspirals. A

\ Instead of forming concave channels in the elevator-platform or covering of the elevatorframe, the spirals I may be placed over openings 132, extending from the top to the bottom thereof and of a width less than the diameter of the spirals, the sides of said openings being beveled orcharnfered to support the spirals and prevent their cutting into the covering of the frame. While this construction is an improvement overprevious plans, and may be used with advantage both for the elevator and raking mechanism, the concave channels are deemed more advantageous, for the reason that they give a better support to the spirals, and also prevent the loss of grain,which is liable to occur when the bottom of the channel is open.

To hold the grain properly down to the elevator-spirals and insure its being carried upward thereby, I employ a float sustained byoverhanging arms M and N, in substantially the same manner as in the patent heretofore granted to me, bearing date October 26, 1880, and numbered 283,781, whereby the grain is permitted to extend outward beyond the float at the back of the machine'. Instead, however, of an endless apron, as in the patent mentioned, I make use of a series of elastically yielding rods, m, attached .at their lower extremities to the bar N and at their upper end to a bar or slat, m', which is in turn suspended by spring arms or supports m2 from the bar or beam M. This construction causes the rods to bear-` with sufficient force upon the grain to insure the proper action of the spirals upon it, even when but little is passing, and at the same time permits ICO IIO

them to yield to accommodate an unusually or beam N, as shown in Fig. 4. This arrangement forms a hinge-joint or pivotal attachment, enabling the iioat to move freely to or from the elevator platform or frame.

Ilhe beam or bar M, which bears the upper end of the float, is supported by a bracket, m3, at the head of the elevator, and `braced by a rod, m4, or in any equivalent manner, and the lower bearing-beam, N, is firmly bolted to a flanged casting, a', attached tothe post or standard E', bywhich it is held rigidly in place.

For the purpose of facilitating and insuring 1 the passagel of the grain from the raking-spirals to those of the elevator and its proper delivery to the latter, a series of star-wheels, O,

is employed, each consisting of a series of ra dial arms, o, having their ends curved slightly backward, as shown in Figs. 3 and 4, and mounted and secured upon a common shaft, o', suspended from the beam N in hangers o2, directly over the space intervening between the raking and elevator-spirals in position to carry the grain from one to the other. A rotary motion is imparted to the star-wheels and shaft by the successive engagement and elevation of the arms of one or more of said wheels by one or more of the elevator-spirals. In order that the grain may not be wound or twisted about the shaft, a shield, P, of sheet metal or other suitable material,is placed thereabout, having` openings p, through which the arms o extend, the curved lower ends of rods m serving also to hold the grain away from said shaft, and to strip it from the fingers as they revolve. i

While I have described the star-wheels as fixed upon the shaft, and prefer to arrange them in such manner, in order to insure an equal advance of the grain at both lends, it will be seen that good results may be attained 'by mounting them loosely upon the shaft and rotating each one as an individual, particularly as the spirals are caused to move in unison.

The grain carried up over the elevator is delivered to a binding-table, an automatic binder, or allowed to fall upon the ground,as is usual in such machines.

Heretofore it has been usual to place the sprocket-wheel and shaft for driving the platform-rake at the junction of the platform and elevator, and for driving the elevator-rake at the head or apex of the elevator, and to lead a chain over them from a master-wheel at the rear outer corner of thelatter. This involves a constantly-moving body over parts liable to be touched by the hand or person of the driver or other attendant, and is therefore objectionable.

In my machine I arrange the shaft b4 for driving the elevator-rake at the angle between the platform and the elevator, the shaft b5 for driving the platform-rake at the outer end of the platform, and their sprocket-wheels immediately outside of the rearsillof the machine, and drive them by a horizontal endless belt,l

R, running behind said sill from the masterwheel 'b3 at the outer base of the elevator. From thiswheel the belt is led over a tightener, r; thence to and beneath the sprocketwheel on the end of the shaft b4; neXt over a support, rf, about midway of the length of the platform, which may also serve to hold it up in mesh with said sprocket-wheel; then over the sprocket-wheel at the outer end of the platform, and returned over the sprocketwheel at the inner end, down under an idler, r2, to bind it to said wheel, and,finally,through the keeper c* to the master-wheel again.

-In orderto brace and strengthen the joint between the platform and elevator, and also to protect the chain at that point and provide firm bearings for the sprocket-wheel and idler, whereby they may be kept in constant relation to each other, I apply a casting, r3, which binds the frame at said point, receives the journals of the idler and sprocket-wheel, and bridges, by means of an overhanging flange, r4, the chain above and for some distance to the side of the wheel, so. that it will not be clogged.

Ordinarily, the master-wheel b3 is keyed to a shaft extending through the machine from front to rear, and bearing at its forward end the crank-wheel by which the cutter-bar is driven. The rrelative speeds of cutting and raking mechanism are therefore determined by the size of the exposed wheels at either end of the shaft. In the present instance it is shownl as divided, so that the `bevel-gear on the end of the shaft b, driven direct from the main wheel, may mesh with bevel-pinions on the inner ends of said shaft-sections b b2, the former bearing the crank-wheel at its front end and the latter the master-wheel b3 atits rear. This arrangement is advantageous when automatic binding mechanism is to be driven from the section b2, as'the pinion of the latter may, as proposed in an application filed by me in the Patent Office of the United States on the 29th day of March, 1881, Serial No. 29,452, be meshed with an inner or narrower rim of teeth on the face of its driving-gear, and thereby be driven with greatest power, .while the pinion of the crankshaft may run on an outer rim for speed.
