UNITED STATES WILLIAM K. MILLER- OF CANTON, OHIO.

IMPROVEM ENT IN HARVESTERS.

Specification forming part of Letters Patent No. 32,707, dated July 2, 1861; Reissue No. 2,296, dated June 2G, 1866.

DlvrsIoN C.

To all whom it may concern:

Be it known that I, WILLTAM K. MILLER, of Canton, in the county of Stark and State of Ollio, have invented certain new and useful Improvements in Harvesti11g-Machines; and I do hereby declare the following to he a full, clear, and exact description` of the construction and operation of the same, reference being had to the accoxnpalxying drawings, making a part of this specification, in which- Figure l represents a perspective view of the machine as arranged for reaping grain, the drivers seat (shown in the separate iigure) beingl removed to show the parzs that would be concealed by it if in place. Fig. 2 represents a vertical transverse section, taken close up to the platform drive-wheel, to show the arrangement of the hinged part of the main frame and its operation.A Fig. 3 represents, in perspective, the main frame proper-that is, that part of the main frame that is supported and controlled by the carrying-wheels and tongue. Fig. 4 represents the drivers seat and the clutch-lever for throwing the cutter in and out of gear, detached and separated from the main frame.

My harvesting-machine is designed for reaping grain as Well as for mowing grass, it being convertible from one to the other at pleasY ure, and equally applicable to both purposes; and my invention consists in the use of a brace on the grain side of the machine, extending from the front end of the frame to and connected with the axle of the drivingwheel, so as to furnish a support for the linger-beam and To enable others skilled in the art to make. and use my invention, I will describe the same with reference to the drawings.

A represents a main frame, united by a bent axle, B, or a brace, near where the journals C U of the wheels are united to said frame, as seen at Fig. 3, whether said brace be the axle or otherwise, and to which frame the tongue D is rigidly fixed. There are also upon this frame boxes a a, in which a cross-shaft, b, Fig. l, is supported and turns, to communicate -1notion to the cutters from the drive-wheels or either of them. It also has'a rigid arm, E, affixed to it, to Which the lever is hinged that raises the linger-bar and platform, and also a short arm, F, to which a brace or bar, G, Fig 1, is fastened by one of itsends, the other end being connected to the point of the journal C', the object of this brace or bar being to conneet the screw-buckle rod o to.

The driving'whecls II H are independent drivers, turningloosely on the above-mentioned journals O O. They have gear-wheels I I attached, which gear with and turn the pinions d on the shaft b when the machine is drawn forward; but when the machine is backed the shaft b does not turn, there being ratchets and pawls xed in the drums e, so that the pinions may turn without the shaft, in the usual wellknown manner. At about the center of the shaft I) there is a bevel-gear, j', which turns a bevel-pinion, g, on a shaft that carries the cranlrwheel h.

A sleeve or boss, t', is connected with the bevel-gear j' and to the shaft b by a feather and groove, so that, by'means of a lever, j, which straddles the sleeve and extends up toward the drivers sea-t, the driver may at pleasure throw said gearjI in orout of connec tion with the pinion g. From the crank-Wheel It there extends a pitman, 7c, which connects with and gives motion to the cutter-bar and cutters.

To the shaft b are hinged two frame-pieces, J J, which extend rearward, and are bolted to the finger-bar K or a prolongation of it, K', so that the linger-bar in rising and falling swings around the shaft b as a center, said shaft being forward of the bearings or journals of the drive-wheels, and, having a longer radius than they could have if hung to the journals or axles of the drive-Wheels, can be more easily raised with less swing of the lever L than though they were hung shorter.

The shaft that carries the bevel-pinion g and crank-Wheel h is supported on these framepicces J J, so that the pinionsA can roll around the bevelgearf and still mesh with it, as the shaft 11 is the common center of all the parts.

To the under side of the framepieces J J, at b, Fig. 2, are hinged two bars, M M, which extend rearward, and to which the foot-board N and the rakers support or stand O are fastened, and which may have a caster, m, underneath them, to keep them oft' the ground, and an upright, n, which may be adjusted and fastn cned to the upright o on the linger-bar; or, if the pin or bolt p be removed, then the rakers stand and the finger-bar can move independent of each other in a vertical line.

The leverL is pivoted to the arm E, and has a grooved arc, q, upon it, and rack-teeth to hold it in any Xed position.

To the arc q is fastened a cord or chain that passes under a roller, 1", and thence to a lever, s, which is connected to the shoe l?, so that the driver, when occupying his seat, can by means of this lever raise up or let down the platform, cutters, and other' connected parts at pleasure', a hinge-joint being provided between the shoe P and the shoe-plate Q, for this purpose, and the fin ger-bar being bolted to the Y shoe P and the brace-bar K to the shoe-plate Q admits of this movement. The shoe and shoe-plate attachment and hinge are the same as that patented to me heretofore, and need not be here further described.

The suspension or tension-rod t is connected to the front of the shoe, and extends up and has its upper end fastened to the brace G. In this rod t there is a screw-buckle, u, by which the point of the shoe may be raised or lowered and held at any desirable height.

R is the outside supporting-wheel, S the outside divider, and T the platform 5 U the outer' reel-support, and V the inner one, for supporting the reel W. The outer reel-post is rigid, but adjustable. The inner one, V, is pivoted at t to a nut or block, w, that is adjustable in the slot .as of the arm X, and the reel-post is made further adjustable by the pin 2 and slot 3 of the plate z, by which it is pivoted to the nut w.

There is a gimbal joint at 4, where the reelshaft is supported to the inner reelpost, V, and this support is made adjustable by the screwrod 5.

On the end of the reel-shaft there is a pulley, 6, around which a belt, 7, passes, and thence around a pulley, 8, near the joint of the hinged reel-support V, and thence around a pulley, 9, on the hub of the driving-wheel, from whence the reel is driven. By this arrangement the platform or finger-bar and cutters may rise and fall7 whilst the reel will swing to admit of this movement, and the belt crossing thejoint between the platform and main frame will continue to drive the reel.

Z is the drivers seat. Its position on the machine-frame will be readily understood by the position of the leverj on the main frame and the same lever shown in connection with the seat in Fig. 4. There is a hole in the lever j that sets over a pinin the upright l() when the wheelfis'in gear with the pinion g, and hooks l1 catch under the front of the main frame to hold the seat firmly to its place.

By placing the shaft b in advance of the bearings of the drive-wheels the power of said drive-wheels upon the pinions on said shaft tends to prevent the drive-wheels from slipping, whilsttlie contrary effect would take place if the shaft and pinions were behind the line of bearings of the drive-wheels.

The swringing reel-support V turns on the pin or pivot t, and can move back and forth past the joint between the platform and main frame, and `the universal joint 4 in the reelshaft admits of this motion without in anywise cramping or binding the reel.

What l claim under this invention, and de sire to secure by Letters Patent, is-

The brace on the grain side of the machine, extending from the front end of the frame to the axle of the driving-wheel, as a support to the finger-beam and the reel-post, substan tially as described.
