IMPROVEMENT IN HARVESTERS.

Specification forming part of Letters Patent No.1 52,622, dated June 30, 1874; application filed March 10, 1874.

To all whom it may concern Be it known that I, AJol-Luv H. ELWARD, of St. Paul, county of Ramsey, State of Minnesota, have invented certain new and useful Improvements in Harvesting Machines, of which the following is a ful1,clear, and'exact description, reference being had to the accompanying drawings, making part of this speci-l fication, in which- Figure l is a plan view of my improved harvester, broken away in part to more fully Fig. 2 is a vertical transverse section online y y, Fig. 1. Fig. 3 is a plan view of the binders carriage,show ing the manner in which it is connected with the machine or mainframe. Fig. 4 represents an outer or stubble side elevation, with the binders carriage removed and the elevator shown in broken section on line z z, Fig.2; and Fig. 5 represents a vertical transverse section through the outer or grain side of the platform and platform-apron.

Similar letters of reference denote corresponding parts wherever used.

i The invention consists, iirst, in a novel combination of stripper-belts with the platform and elevator aprons; second, in a novel construction of the elevator, whereby the elevatorapron can be made to move in either direction, and isl adapted to elevate the grain by either its upper or lower face acting thereon, as the circumstances under which the grain is harvested may suggest or require, and as hereinafter explained 5 and, lastly, the invent-ion consists in certain details ofconstruction and arrangements of parts, all as hereinafterfully set forth.

- In the accompanying drawings, A represents the main drive-wheel; A', the outer platformcarrying wheel; B B1 B2, the main frame; CO1, the elevator-frame; D Dl the platform -and elevator aprons, all of usual'or any preferred construction. The bottom of the platform-frame, underneath the apron D, is tightly closed by a wood or sheet-metal bottom, d,

and this bottom, in connection with the closed end at di, forms a receptacle for such grain as may be shattered or thrashedout in cutting and conveying the same to the inner end of the platform. At the outer end of the apron D (see Fig. 5) is placed a concave, d2, conforming in curvature,.or nearly so, to the sweep of the teeth on the slats of apron D, and extending from the horizontal plane of the bottom board, d, to the vertical plane of the end or divider board, d1, as shown, for enabling the teeth of the apron D to piek up and return any grain or straw that may fall between the divider-board and end of the apron, or otherwise get under said apron. With this construction tlie usual inclined overhanging dividershield may be dispensed with, if desired. The elevator-bottom C? is slotted, as shown at c in Figs. 1 and 4, to permit the ends of the teeth on the elevator-slats to pass below its upper surface, on which the grain rests, and up which it is carried, in such manner as to avoid the objectionable frictioual contact of the teeth with such upper surface usual to the close bottom of elevators of this class as heretofore constructed, while at the same time it insures the regular and even elevation and delivery of the grain. A box or receptacle, E, extending from front to rear of the elevator, is pivoted underneath the elevatorframe, in the transverse front and rear bars, B, of the frame, and serves to receive and retain such shattered or shelled grain as may escape through the slots c in the elevatorbottom. The platform may be provided, if desired, with a series of rods or wires, b, arranged over the apron D, connected at their outer ends with the end or divider board d1, and at their inner ends with the elevator-bottom C2, near its lower end, as shown in Figs. l and 2, said rods or wires forming a stationary platform, on which the grain falls as it is cut, and between which the rake-teeth ofthe apron D project for removing the grain; or the rods b may be dispensedwith, and in lieu thereof a series of curved lingers, bf, attached to the elevator-bottoni C2, at or near its lower end, or to other convenient support, and extending outward into suitable position totake the grain from the teeth of the slats of the apron D, as shown, the rods b or b', whichever may be employed, serving to strip the grain from the rake-teeth of apron D. At the inner end of the platform-apron, andA in close proximity to the inner apron-roller, is arranged :a horizontal shaft, upon which is placed a series of fast pulleys, F, and upon the opposite side of or underneath the elevator-bottom G2 is arranged another shaft, similarly provided with fast pulleys F1, upon which are placed a number of stripper bands or belts, F2, which pass through slots in the elevator-bottom, and are armed upon their outer faces with teeth j", which, when the belts are rotated in the same direction with the apron D, pass in close proximity to the inner end of said apron, or to the slats and teeth thereon, and serve to take the grain from the platform-apron and to convey it inward within reach of the elevator.

A similar arrangement of stripper-belts is made at the upper end of the elevator, to take the grain from said elevator and convey it to the desired point of discharge, Gr G' indicating the rollers or pulleys, and g the stripper-belts, the shafts of which are mounted in bearings in a frame, H, which has a horizontal pivotal connection, orI h h, with the top ofthe elevatorframe, for permitting the stripper-belts to be set or adjusted to any desired angle of relation to the elevator-apron, and to vary the elevation at which the grain is discharged from the stripper-belts. The stripper-belts are made to move in the same direction with the aprons from which they take the grain, being operated by belts and pulleys, as shown in Fig. l,

n or any other suitable or preferred arrangement of mechanism'for the purpose; and when the grain is carried up by` the elevator-apron actin g underneath, tkmipper-belts also act underneath, as indicated by the arrows in. Fig. 2, and the grain is carried across a flooring, h', of the-pivoted stripper-frame H to the desired point of discharge; but where, from any cause, such as a damp or sticky condition of the grain, it may be found desirable to carry the grain upward on the face of the moving apron D' itself, by simply crossing the belt which drives said apron, the direction of movement of both the elevator-apron and its strippin g-belts g will be reversed, causing` the grain to be carried upon their upper faces from the stripper-belts f to the point of discharge. Under this arrangement the grain is held down upon the upper inclined face of apron D' by yielding spring-rods i, secured at their lower ends to a cylindrical rod, I, which is suspended by springs j from the seat-plank J which overhangs the apron D', being supported upon projecting bars J' in front and rear of said apron. rlhe upper ends of the rods z' are left free and overhang the upper end of the elevator-apron, as shown, said yielding rods serving to gently hold the grain to the face of the apron with out materially resisting its progress until it is delivered to the stripper-belts. The supporting-rod I, which forms, as it were, a mouth-piece for straightening the grain and admitting it to the elevator by its cylindrical form, facilitates the admission of the grain, and offers the least kpossible resistance to its passage. The reel-shaft K, atits inner end, is mounted in a horizontal longitudinal bar, K', which is adjustably connected with the uprights C of the elevator-frame, a series'of holes, k k, and the fastening bolts or screws k1 permitting the vertical adjustment of the bar K' and reel-shaft K, and a series of notches or bearings, k2, or an adjustable sliding box, permitting the horizontal or backward and forward adjustment for adapting the reel to the condition of the grain. f

A similar construction may be employed for adjusting the outer end of the reelshaft. Guide-pulleys Z Z for guiding the reel-belt are mounted in a bell-crank arm, L, pivoted at its lower end to an upright or post, O, of the elevator-frame. The upper horizontal arm is provided with a curved slot, and connected with the post by a bolt or set-screw, which permits its adjustment forward or backward on the lower pivoted end for regulating the tension of the reel-belt. M, Figs. 1, 2, and 3, represents a binders carriage, consisting of a rectangular frame, of any suitable construction, mounted upon wheels N, with its inner side, M, parallel with the outer or stubble side of the main frame, and connected therewith by links O 0, pivoted at one end to the binders carriage, and at the other to the main frame, one in front and the other in rear, as shown in Fig. 3, by horizontal pivots at right angles to each other, to accommodate the independent movements of the binders7 carriage, while at the same time always holding said carriage in proper relation to the machine to receive the grain as it is discharged from the elevator. A dragbar, P, pivoted at its forward end to the main frame, and at its rear end to the binders carriage, serves to draw the carriage as the machine is drawn forward. rlhe carriage has an upright frame supporting the bars Q, which form a seat or lateral support for the binders standing on the platform or flooring of the carriage M. Q'

Q are longitudinal bars, connected by a series of transverse rods or wires, q, upon which the grain is caught as it is discllarged from the elevator. The frame of the binders carriage may be closed, either in whole or in part, as at m m, upon its sides, to form a receptacle for shattered grain. tends upward the height of the frame, forming' a fender or shield against the Working parts ofthe machine, and a loose sheet or canvas, R, connected with the upper end of this shield M, and with the outer swinging end of the elevator, serves to prevent any grain from escaping in its passage from one to the other. Sufficient slack is provided in this apron R to permit the free movement of the binders ca rriage relative to the apron, and also the adjustment of the pivotal frame H as desired.

Parts of the machine not particularly described may be made in any usual or preferred manner.
