A is the main wheel; a, the main axle, upon which this wheel is mounted and to which it is usually keyed; B, the seat supported upon a bracket 1), sleeved to said axle outside of the main wheel, or on the stubble side thereof, and O a brace rigid with said support or bracket and extending therefrom to a pendulum guide or keeper 0, secured to the tongue by the hound-bolt, whereby this brace is made not only to support the seat and cause it to follow the adjustment of the tongue, but also acts as the outer hound to said tongue. Upon the inner end of the axle is sleeved a bracketcasting D, having a rearwardlyextending radius-arm d, secured to the prime-pinion shaft 61', carrying the prime pinion (1 which meshes with the main gear E, mounted on the axle outside of the bracket-castin g and driven therefrom by a one-way clutch. In front of the axle the casting has a vertical segmentrack f for the raising and lowering and supporting lever F, pivoted at f, concentric with said rack and having the link f depending from its crank-arm f to a connection with the frame-bar. This frame-bar G extends from a pivotal connection 'with the drafttongue at the point where the hound-bolt passes through the same to a keeper at the rear of the gear-frame, and upon this bar is mounted a segment g, into which the tippinglever G, pivoted at g to said 'bar, latches, and a link 9 from the crank-arm g of said lever depends therefrom to a connection with the gear-frame at or adjacent to the joint between said frame and the tongue.
As thus fardescribed, the machine does not essentially differ from that made the subject of my before-mentioned patent, except in respect to the outline of the frame-bar and the relations thereto of the lifting and tilting apparatus, as will be presently explained. In said former patent the sills of the platform were brought close up to the main wheel and constituted the gear-frame-that is, they afforded the supporting base for the metal. brackets or bearings carrying the primepinion shaft and for the rake-standard, sufficient space for these in strumentalities of course being left between the platform proper and the wheel, and also a point of support for a metal bracket bolted to the front sill, practically in line with the crank-shaft, to receive the pivot-bolt of the hinged tongue. I now, however, replace the inner ends of these sills by a metal frame consisting of a casting H, having one sleeve-arm h, parallel with the main wheel or in line with the advance of the machine, and constituting the bearing for the cutter crank-shaft H, which it incloses,and
To an offset from the side of the box, and near the bottom thereof, is riveted an arm orbar h of wrought metal, (though it may be cast integral, if desired, or formed of malleable castiron,) parallel with the front arm of the casting and occupying substantially the place of the rear sill in the former construction. This metal framethus forms a low-down rectangular gear-frame suspended from the main axle and entirely beneath it at practically the level of the platform, to which it is to be connected, as presently described.
The frame-bar as alread T intimated is ivoted to the tongue by the honnd-bolt and plays in a keeper at the rear of the gear-frame; but instead of being practically straight, as in my former construction, it is curved, as shown, to form a sort of arch or bridge h at the point where it supports the segment for the tiltin g-lever and an inverted arch h* where the link from the lifting-lever is pivoted toit, thus securing greater strength or resistance with the same metal or the same strength with less metal and weight.
Near the outer ends of the lateral bars of the metal frame are ears 2' to receive a rod I, parallel with the side of the main wheel, and a lug i, rising from the inn er shoe I, secured to the finger-bar and platform, extends up alongside the front ear and also receives said rod, while a strap or oifset 1' from said platform embraces the rod alongside the ear on the rear bar of the gear-frame, permitting the platform to hinge upon said rod and to be turned up to or past a position at right angles with said frame. The front bar of this gear-frame is extended beyond the pivotal IIO connection, as at 4*, and a bolt 1?, passing through said extension, clamps the shoe, and consequently the platform, rigidly to the frame, making a stiff platform for use.
The hound K, which connects the shoe with the tongue, is jointed to said shoe by a universal pin-coupling or swivel 70, having its main pivot 71; in line with the rod upon which the platform hinges and the transverse pivot 70 in line with the hinge-joint between the draft-ton gue and gear-frame, so that no strain shall be brought upon said hound whenever the platform is folded for transportation, or when it is raised or lowered or tilted by the appropriate levers while the machine is in operation.
A crank-shaft L is carried in bearings beneath and alongside the rear bar of the gearframe, and the crankl at its inner end is connected by a link Z with the main axle, as in the machine upon which this is an improvement, while the crank Z at its outer end is link-connected with a similar crank m on a second crank-shaft M, running beneath the platform a short distance behind the fingerbar, and carrying at its outer end a crank m, receiving a detachable stub-axle m for the support of the grain-wheel.
The link N, which connects the adjacent cranks of the two shafts or shaft-sections, is preferably secured to the crank on the inner shaft by a spring-pin n, which can bereadily withdrawn to uncouple the link, but will always remain attached thereto, and the stubaxle is so formed, and secured by nuts to its cranks in such manner that it may be readily removed and with the grain-wheel applied to the crank on the inn er shaft whenever the link is uncoupled therefrom. Thus whenever it is intended to remove the machine from one field to another or take it along the road from or to the house the link will be uncoupled from the crank Z at the platform end of the gear-frame, the grain-wheel detached from the crank alongside the divider, the bolt which clamps the fin ger-bar stiffly to the gearframe will be removed, the platform folded up and secured by a stay-rod extending to any appropriate part of the frame, and the grain-wheel will then be mounted upon the crank Z and serve as a carrying-wheel at that side of the gear-frame.
I do not intend to limit myself to the specific means of communicating motion from the inner section of the subtending crankshaft to the other, nor to the employment of the other novel elements of my invent-ion in connection with a gear-frame and frame-bar (if the precise construction and outline described alone, nor to the use of a double pinjoint as the universal coupling between the hound and inner shoe, since in the last case a ball-and-socket joint is a'full equivalent; but
