IMPROVEMENT IN HARVESTERS..

Specification forming part of Letters Patent No. 16,873, dated March 24, 1857 extended seven 'years 5 reissue No. 5,115, dated October 29, 1872.

To all whom it A'may concern: l

'Be it known that I, GEORGE ESTERLY, formerly of Hart Prairie, now of Whitewater, in

the county ofWalworth and State of Wisconsin,

have invented certain new and useful Improvements'in Harvesters; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, reference being had to the accompanyingdrawing making part of this speciiication and to the letters of reference marked .thereon,like letters indicatinglike parts wherever they occur. Y To enable others skilled in the art to construct and use my invention, I will proceed to y describe it.

,Y My lllelllfiou relates to machinesl for cutting..

grain orgrass; and the invention consists in so hinging the draft-bar to the main frame f the machine in rear of the axle, and at or nearI side supporting-wheel. The Wheel A has its` bearing in a rectangular frame, G, from which extends laterally the cutter-beam l), and arear beam, E,'which are united at their outer ends by a girt, F, to which the outer wheel B is 'attached. On the rear beam E or near to it are arranged two supports, G, to which is pivot'ed4 the rear-end ,otl the `reach or draft-,bar H, the,`

front Jend' being provided with a bolster, I, and 'resting onl a truck, J, yto which it is pivoted, so that the wheels may turn freely under the reach. The tongue'L maybe loose and thus 4the horses necks will be relieved of Weight.

A bar, M, is secured vupon the reach at or near its center, through a mortise in which there extends up a forked bar, N, hinged at'its'lower' end to the cutter-band), and having ratchetteetlrc on its opposite edges, as shown in the drawing. Another bar, U, is attached to the reach infront of the bar M, and has pivoted on it alever, P, the front end of which passes under the drivers seat Q so as to be conveniently reached by the driver, whileits rear end is forked so as to straddle the shank of the supporting-bar N. rIhe edges of the prongs f of this forked portion are beveled or rounded oil' next to the bar Nto prevent their catching in the teeth c. Outside of the prongs f, andy attached to the bar M, are two sprin g-do gs, g, which engage Withthe teeth of the support N to hold up Vthe cutter-beam or front of the main frame at any fixed height desired, When it is desired to lower the cutter-bar, the driver places .his foot on the front end of lever.P.

andprcssing it down raises the opposite end, thereby bringing the prongs f up against the spring-dogs g, throwing them out of theteeth c,.when .thel front or cutter bar will drop.V By Y .releasing the lever P the dogsg will again catch in the teeth and hold the frame suspended, as before.' On the-rear beam E, and' near the rakers seat R, is secured a lever, S, by wl1ich the raker can raise the front of the machine at will, the springdogs g catching in the teeth c and holding it up. The

elasticity of the spring-dogs gis suiiicient to allow them to yield a little when theV weight of the frame bears on them, thus preventing any sudden shock or jar and, in order that the raker at his seat may do both the raising and lowering ot' the cutter-bar, a cord, may

run from the front end of the lever P over suit-l able pulleys to or near the rakers sea-t, so thatv by drawing on the cord the dogs may be released and the front of the machine be allow` d to drop, as-before stated'. The spreading of the reach or draft-bar and hinging it at the rear of the machine, not only facilitates the turning around of the machine, but prevents 'all racking of the Vfra-me. `supporting-bar N, spreading laterally at .its lower, end Where it is connected to the cutter- Besides this, the

bar, helps to brace the parts and tends to throw the weight of the machine onto the main wheel A and4 thus assist to' counteractside draft. The reach or draft-bar is placed inside of the Y main wheel A, or between it and the outer end of the platform or cutter-bar, so as 'to support as much of the outer part ofthe machine as po'ssiblc withoutl interfering with the cuttingV of the standing l grain. The platform T is hinged' at its front to the cutter-bar D, and is' connected at its rear tothe beamjl by screw- When sufficient grain has accumulated onthe` platform, to form a gavel it is turned so as to brin g the heads` of the grain toward the daslb board, when it is pushed oil' en dwise, the heads of the grain striking against the hoard U, when it falls at once to the ground in a compact bnndleeonvenient for binding.

'By'hinging the draft-bar to the mainframe at or near the rear end, as shown, and in rear ot' the axle or supporting-Wheel, it will be seen that when the team is backed, the front ofthe machine will have a tendency to be raised from the ground7 and that when the team moves forward the front will be held down and made te follow the nndulations of the surface, when not held up by the degs g, and thus .it may be used either as a loose or rigid frame at will, the former being best adapted for mowing, and the latter for cutting grain.

I am aware that it has been'proposed to oonstruet a reaper having 'its draft-bar pivoted to the main frame'slightly in rear of the journal of the bearing-"Wheel7 and in which a lever is pivoted to'standards attached to the front of the rear frame, and in which the cutter-bar is elevated by means of said lever; and, there fore, I do not elaiin euch; but

Having described my invention, what I claim l. A reaper having its main frame Cmounted so as to tip or swing on its bearingwheels,

and having its draft-bar hinged or pivoted to Witnesses EDWARD P. BURRoWs, J. H. Riera.
