SPECIFICATION forming part of Letters Patent No. 491,746, dated February 14, 1893.

Application filed December 7, 1885. Serial No. 184,893. (No modal.)

To @ZZ wltom it may concern:

Be it known that I, OLE O. STORLE, of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Harvesters; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled inthe art to which it pertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to that class of harvesters popularly called low down machines.

Its objects are, rst: greater compactness, lightness and simplicity and second, a better balanced, easier running machine. These objects I attain by the use of the improvements hereinafter described, which consist essentially of a canvas orconveyer peculiarly constructed. and arranged to receive the grain from the straight canvas or apron upon which it falls when cut, and convey the same in a curved path at one side of the driving Wheel to and upon the binder table, thereby dispensing with the elevators and their actuating mechanism commonly employed to raise the grain up and over the driving wheel.

In the accompanying drawings like letters refer to the same parts in the several figures. Figure 1 is a plan View of a harvester embodying my improvements a portion of the rear platform being broken away to disclose the gearing underneath the same. Fig. 2 is a like view of the machine, the canvases or aprons and the platform atthe rear thereof being removed to disclose the underlying parts. Figs. 3 and 4t are detached detail views of the packers, Fig. Sbeing a plan view and Fig. l a side elevation thereof and Fig. 5 is a side elevation of the butter and its connections.

A A represent the frame work of the machine, M the drivingwheel, T the grain Wheel supporting the machine at the opposite end in the saine vertical plane with said driving wheel M, G the finger bar provided with the outer and inner divider points H H', all constructed and arranged in the usual manner.

B is a canvas belt or apron provided with transverse slats 6, Z), and mounted just behind and parallel with the finger bar G upon cylindrical rollers, I, I', the upper half of said apron being arranged to travel toward the driving wheel M and catch the grain as it falls from the scythe and carry the same to, and deliver it upon, the curved canvas or eonveyer C. Said conveyer C is provided like the apron, B, with transverse slats, c, c, by which it is partially stlfened aud main- ,tainedin its proper shape and position, approximately the quadrant of a circle. It is mounted upon the conical or frustum-shaped rollers, L, L, and is provided about its front or longer edge with the chain belt r, suitably fastened thereto, and engaged by the sprocket wheels Z, l, upon which it is mounted and turns and by which the canvas is not only retained in position upon the rollers L, L, but is also positively driven at both ends. The chain-belt r is composed, as shown in Fig. 1, of links suitably shaped to conform to and maintain the curve of the conveyer, and to work properly with the beveled faces of the sprocket wheels Z, Z.

The shafts of the several rollers I, I, L, L, are suitably journaled in convenient parts of the frame-Work of the machine, and the upper sections of the apron B and curved conveyer C are supported at the sides by the cleats or guides a, a, a', a', the guides a', a', being curved to conform to the contour of said conveyer C. The shafts of said rollers L, L, are extended rearward and are provided with the bevel gears n, n, which mesh with a similar idler, o, upon its opposite sides. The gear n', meshes with another similar idler, q, attached concentrically to a smaller bevel gear p', meshing with a similar gear p, mounted upon the rearward extended end of the shaft of roller I. One of the rollers L, L, I is connected in any suitable manner with some convenient part of the machine from which 1notion is transmitted through the intermediate mechanism just described to the apron B, and curved canvas C.

The gears, n, n', o, and q, and the gears, p, p', being of the same size, and the larger end of the rollers L, L, being larger than the roller I, the front edge of the curvedcanvas C is caused to travel faster than'the apron B. At
