UNITED STATES PATENT OEEoEo JOHN H. ELWARD, OF ST. PAUL-MINNESOTA, ASSIGNOR TO HIMSELF AND WAYLAND S. GOODHUE.'
IMPROVEMENT IN HARVESTERS.
Specification forming part of Letters Patent No. 127,324, dated May 28, 1872; reissue No. 6,403, dated April 27, 1875; application filed March 5, 1875.
To all whom yit may concern:
Be it known that I, JOHN H. ELWARD, formerly of Polo, Illinois, but now of St. Paul, county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Hari-'esting-Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing making part of this specilication, in which- Figure 1 is a perspective view of the machine arranged for reaping. Fig. 2 is a vertical longitudinal section of the same, and Fig. 3 is a perspective view of the mower.
Similar letters of reference denote corresponding parts in all the figures.
The lirst part of the invention consists in mounting the secondary or bevel-wheel shaft and the support for one end of the main axle of a harvesting-machine upon a removable gear-plank or framc,in such manner that said gearing and frame may be readily removed from the reaper and combined with a separate mowing attachment. The second part of the invehtion consists in making the binders platform in two parts, one part of which is hinged, and may be used as' a dropper. The invention further consists in certain details of construction, as will be hereinafter explained.
In the drawing, A is the main ground drivewheel, supported in curved tlanges a; but, as these ian ges and the devices connected therewith have been fully described in a prior patent granted to me, they need not be particularly described here. One pair of the iianges is mounted upon thelongitudinal bar B of the main frame, and the other pair upon the gearplank C, shown plainly in Fig. 3. D is a drivin g-wheel, mounted upon the secondary or pinion shaft, driven from a spur-gear, A', attached to the inner face of the ground-wheel A. Wheel D corresponds to the bevel-wheel, which is ordinarily employed in a machine ot' this class; but, instead of having a bevel-gear upon its periphery, has two or more concentric circles of pert'orations or sockets cast or cut in its face, with which the teeth or spurs on the periphery of crank-shaft pinion E', on
crank-shaft B, engage-the construction and arrangement of these parts being fully shown in Fig. 2. Gear-plank O is in one piece, and cut vout or mortised to permit the gearing to be conveniently mounted thereon, in order that it (the gearing) may be readily transferred from the reaper to the mower, and vice versa. In the machine as used for a reaper, Figs. 1 and 2, F F' are the grain-platform sills, one at the front edge and the other at the rear, by means of which the platform is connected with the gearing, and upon which the elevator, reel, and binders stand are supported. G is t-he carrying-wheel. is applied to the harvester it is mounted upon the adjustable hanger G', but when the machine is used as a mower, it (the wheel) is secured to a short shaft, g, which is mounted in a suitable bearing, g',attached to the under side of the gear-plank c. H is a carryingbelt, arranged behind the cutting apparatus. H' is the elevator, provided with transverse knife-edged slats h,notched,as shownin Figs. 1 and 2, to receive the wires or rods which compress the straw upon the elevator during its passage over the same. hl are rods attached at 'their lower ends to bars 7b2 extending from sill F to sill F', and at their upper ends to roller I, mounted in suitable bearings on theunder side of the elevator in such manner that it can be rotated without disturbing its relation to the rods, for a purpose which will be explained.
I' are lingers, projecting at suitable intervals (usually about a foot) from roller I. f f1 are standards or braces, rising from sills F F', to support the rear or upper end of the elevator. f2 is a ratchet-plate, attached to standard f1 at the rear side of the machine. K is the tongue, pivoted to the gear-plank. K' is a tilting-lever. One end of this lever is rigidly attached to the tongue a short distance in front ot' the point at which the tongue is piv-` oted to the gear-plank, and the other end engages with the ratchet-plate f2. By means ofthis lever the platform may be tilted upon main drive-wheel A, and the grain or carrying wheel Gr, as will be readily understood. L are posts, rising from the stubble-ends of sills F F'. L' is a grain-guard, serving to prevent WVhe-n this wheel the grain from becoming entangled with the driving-wheel. Mis one of the reel-bearers. The lower end of this bearer is supported upon aV bracket, m, attached to the main frame, the upper end being supported by a bolt or pin passing through the slotted end of a rail, M', which, by preference, is made long enough to extend across the machine, and is secured to posts L, or bars attached to said posts. The other reel-bearer is not shown but may be located at the inner or outer corner of the platform, as it is desired. NN are horizontal bars, supported upon posts L and standards f f1, or the frame of the elevator. O is a bar, bolted to the overhanging ends of bars N N. O is a secondary bar, suspended from bar O, and provided with a number of elastic compressing-rods, o, which are bent and arranged substantially as shownthat is, so as to lie parallel, or thereabout, with the elevator -apron, at a short distance from it, thereby serving to conline the grain to the apron, and thus to render the operation of said elevator more certain. The upper ends of rods 0 are bent down ward to insure the delivery of the grain upon either the grain-receiver or the dropping devices, which will be explained hereafter. P is the seat, and P the seat-support. The seat is adjustable upon the support by a bolt, which can be passed through either of a series of holes,p, and the support is pivoted to bar N, and can be adjusted upon bar N by means of bolt-holes p. Thus the weight of the driver can be employed to balance the machine, as may be required.
Q Q are hangers, from which the outer side of the binders7 stand or platform is suspended by links Q Q. These hangers are pivoted to the posts L at l, in such manner that they can vibrate vertically. q is a stop, on bar N, which limits the upward throw ot' the inner end of the hanger, and there is a similar stop olrbar N1. R is a binders platform, hinged at its inner side to the main frame, 'as at r, Figxl, and pivoted at its outer edge to links Q. The Hoor or platform is made in two parts, the inner part or dropper R1 being hinged to the outer part, so that it can drop into the position shown in full lines, Fig. 2, when actuated by certain devices, in a manner andfor a purpose which will be explained. In practice, I prefer to hinge the dropper R1 by means of pivots, and to the rear pivot I attach a crank-arm, rl, Fig. 2, in about the relation to the dropper shown in this ligure. B2 is a second dropper, arranged above drop-4 per R1, and pivoted upon the hangers Q Q. Dropper B2 is also provided with a crank-arm, r2, the position of this arm, relative to dropper B2, being the reverse ot' crank-arm rl, relative to dropper R1. The crank-arms are connected by means of a link, S, and are operated by a sliding link, S', which extends past the side of the elevator to within convenient reach of the driver while riding in seat P. The free end of link S rests in a suitable guide, s, and is notched upon its down side, in order that it may be lockedin any position in which it may be placed by the driver. T is a partition board or fender, arranged in a vertical position outside ot' the droppers. It is secured to hinges Q Q by pins t, or equivalent devices, in such manner that it may be easily removed. U U', Fig. 3, are two short sills, which, with bar or sill B, and gear-plank C, form the frame ot the machine, when adapted for mowing'. In Fig. 3, the cutting apparatus is hinged to the main frame, and may be lifted, for passing obstructions, by means of lever V and link n. In this gure the lifting-lever is shown pivoted to one of the inclined side pieces of the elevator; but it is obvious that some other form of support maybe employed. In this figure the seat is shown supported from the outer side of the frame, this change being made to balance the machine.
In the drawing the machine is shown as it is intended to be used for a side-delivery dropper, the parts being arranged in the position into which they are moved when delivering a gavel upon the ground, the straw being now received upon the upper' dropper B2. As soon, however, as the gavel is delivered, the driver thrusts link Sl backward-thatis, from himand the two droppers are simultaneously thrown into the position indicated in dotted lines in Fig. 2. By this movement the grain which was accummulated upon dropper R2 is delivered upon dropper B1, Where it lies until enough has been added to it to make a gavel of the desired size, when the driver draws link S1 toward him, and the gavel is dropped upon the ground, the upper drop B2 serving as a cut-off to prevent the grain. from straggling while the lower drop R1 is open, as will be readily understood. J
When I wish to bind the grain as it is cut, I remove the fender T and drop R2 and lockdrop R1, up in ahorizontal position, and, when deemed advisable, add a box or receptacle for the shattered grain, and such rails or other supports for the binders, as I' may prefer. The roller I is then turned around until linger I1 assumes the position shown in dotted lines, Fig. 2, thus forming a receiver in which the grain is deposited from the elevator, until enough shall have accumulated to form a gavel, when it is removed and bound.
In order to con vert the reaper shown in Figs. l and 2 into a mower, as shown in Fig. 3, it is necessary to take the end sill or bar B, gearplank C, with the gearing and tongue mounted thereon, and the main drive-wheel A from their places on the sills F13, and secure them together by the short sills U U. Then take the seat P and its support P and attach them to the frame, (preferably on the outer side as shown,) bya socket or suitable device. Next hinge the cutting apparatus, and add the liftin g-lever V, link c, and a suitable support for l them.
In practice I prefer a support which is made on purpose to be used with the mower instead of taking any part of the reaper, as the eX- pense is but slight, and it is much more convenient.
By adding the grain-wheel to the inner side of the gear-plank the mower is ready for operation.
I am aware that reapin g-machines have been built, in which the gearing, with the exception of the cogged driving-rim on the main carrying-Wheel, was mounted upon a single plank piece or frame complete in itself, and adapted to be removed from the rest of the frame-work of the machine; but in this construction there was no especial adaptation of the removable parts to fit them for being embodied in a mower, whereas in my machine the construction of the gearing andthe gear-frame is such as to facilitate its transfer from a reaper to a mower. Thus the secondary gear is intended to impart two distinct rates of speed to the cutters, and the hangings for the main wheel permit of the gear-frame being supported at di'erentheights, these two features being practicallyindispensable in a combined machine.
It will of course be understood that as the crank is located at the rear end of the gearplank a transmitting-lever must he employed to drive the cutters, which are to be arranged at the front edge of the grain-platform when the machine is reaping.
By arranging the seat as shown I use the bars N N' O for supporting both the seat P and the guidingrods 0.
It will be readily seen that, as the hangers Q and platform R are pivoted to the framework of the harvesters, and the linksQ' are pivoted to the hangers and the platform, these devices, together with dropper R2, when it is in position on the machine, canA be folded up compactly for passing through gateways and similar contracted places. As the grain passes over the upper end of the elevator H', the wires h', which are bent into nearly vertical position instead of conforming to the path of the elevator, insure the delivery upon either the grain receivers or the droppers, and serve to prevent it (the grain) from clinging to the slats h.
Certain features of construction and arrangement, hcreinabove described, are ernbraced in another application, and are not here claimed. A
I am aware that a carrying belt or apron with transverse slats, havin gprojecting spikes or spurs, has been used in this class of machines, but I regard the knife-edged slats used in my machine as being a decided improvement upon the spurs, for the following reasons: As the grain frequently falls in a somewhat tangled condition upon the platform, it is very desirable to straighten it be. fore it is delivered to the binders. It is difi cult, if not impossible, to do this on those elevators in which spurs are employed, because they penetrate the straw, thus keeping it in the same position while it is being elevated, and deliver to the grain-receiver substantially in a swath; whereas in my construction the slats present, as nearly as possible, a continuous knife-edge, broken only by narrow notches to receive the Wires. v
As the grain is carried up its progress is retarded by the wires, the greatest pressure bein g exerted immediately over the slats, and wherever there is any accumulation of straw. It will be apparent that under this construction and arrangement of devices the straw will be pulled apart and divided at each slat, and will be discharged into the receiver in small handfuls, thus greatly facilitating the operation of binding.
Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. In a machine for reaping grain, a removable gear and gear-frames, said gearing being adapted to drive the cutter at different velocities, and the gear-frame being constructed, substantially as described, so that itcan be supported upon the main wheel at different heights, substantially as and for the purpose sot forth.
2. The binders7 platform, constructed of two parts,R It', hinged to each other, substantially as described, so that one part may be operated as a dropper, substantially as set forth.
3. In combination with the bar I, to which is attached the upper ends of rods h', the iingers I', whereby said bar I is made to serve both as a support for rods h' and as a head for its rocking-grain receiving-lingers, substantially as set forth.
4. The combination, with broad, endless elevating-apron, upon the moving-surface of which the grain is carried to the. outer or stubble side of the machine, of the knifeedged slats h, arranged and operating as described.
5. The combination, with the secondary elevating-apron H', of the knife-edged slats h, and the compressing rods or wires o, substantially as and for the purpose described.
