Specification "forming4 plafrt of Letters Patent No. secas, dated December 6,1859', Reissue Nojeoo, dated,

June 20, 1865.

To all whom it may concern.- 1 1 Be it known'that WILLIAM OoGsWELL and IRAYGOGSWELL, Jr., both of Ottaw a, in the county of La Salle and State of llli'noii., did invent a new and Improved Harvesting-Machine; and we do hereby declare that the following is afull, clear, and exact description of' the same, reference being had to the accompanying drawings, making part of this specification, in which-- Figure 1 is a side sectional view ofthe invention. Fig. 2 is a horizontal section o-f the same.

Similar letters of reference indicate c orresponding parts in the two igures.

The object of this improvement is to enable the pinion, which rotates in a permanent bearing in' the frame, and is connected with the' ptman, to run at different speeds and in different directions, -by each of which results special beneficial results'a're attained, as will hereinafter appear. The object is attained by providing the driving-wheel with two distinct gear wheels and making its axis movable forward andsbackward, so as to bring leith'erone of the gears into engagement with the pinion, or the latter vequidistant between the two cogwheels and out of gear.

To enable those skilled in the art to fully understand and construct the invention, we will proceedto describe it.

A represents the main frame of a harvester, and B the finger-bar attached thereto. The main frame maybe of the ordinary rectangular form, as shown in Fig. 2.

C is the driving-wheel, tted loosely on its axle D, thelatter being placed iu a frame, E, the forward part of which is'itted loosely on a journal, a, and `a shaft, b, the'journal and shaft being in line with each other, as shown plainly in Fig. 2. The frame E is allowed to rise and fall freely in consequence of being fitted-loosely on its journal and shaft, and it may be secured at any desired height within the -scope of its movement \by pins c, which pass through segment-bars d d, attached to .the main frame. The journaling ofthe axle D iu the rising and falling pivoted frame is merely a method of providing for the rising and falling of the main frame, as the machine vis regulated for cutting at a greater or less height from the ground. Other means for .permittingthe rising and vfalling ofthe-frame pensed with. The axle D ofthe driving-wheel C has eccentric journals formed at its ends, and is journaled in the frame E, so as tofturn therein.

To the axle D 'a lever, F, is attached, said lever being fitted between pins f fhgl g, or h h in a semicircular plate, F, attachedy to the main frame, said pinsl and lever securing the axle D in three dili'erent positions. The driving-.Wheel is so journaled on ythe axle as to be moved forward or backward by the partial rotation of the axle, ou which it runs freely.

To the outer side of vthe driving-wheel C a toothed wheel, G, is attached concentrically, and a geared ange, H', is also attached concentrically to the outer side of the drivingwheel, the flange H being near the rim of the wheel. v

On the inner end ofY the shaft b a pinion,-I, is placed, said pinion being tted in the space between the geared ange H and wheel G, the diameter of the pinion being less than the width of the space between the geared flange H and wheel G. A

From the above description it will be'seen that the pinion I may be made fo gear into either the ange H or wheel G by simply turning the axle D, the result being due to the eccentric journaling of the'axle D, the drivingwheelU shifting as the axle is turned. It will .fit between the geared flange and wheel, so as not to be engaged with either, in the .latter case the lever F being itted between the pins ff, as shown in black, Fig. 1. When the pinion is in gear with the wheel H ,the lever F is ttedbetweenthe pins ee, and when in gear with the flange H it is fitted between the pins gg. When the pinion I is in gear with the Wheel G the'shaft b, from which motion is communicated to the sickle, will rotate slower than when saidl pinion is in gear with the Bange H, and consequently the speed of the sickle may be adapted for cutting either grass cutting grass than is necessary for 'cutting grain. 1u cutting the latter the sickle-is raised considerably higher than in cutting grass, and

may be provided and the pivoted frame E dis.

also be seen that the pinion I may be made to or grain, a quicker motion being required for' this adjustment' of the sickle is eeoted by simply adjusting the frame `E at a greater or less height by means of the pins c c in the segment-bars ld d, o'r by any equivalent device for raising and lowering the frame relatively to the driving'and supporting wheel G. Besides the advantage of the change of` speed, the change of the motion of the gearing makes the cogs Wear evenly on both sides, presunling them to be equally used, andthe crank-wrist Wears round instead of flat, and the durability y of the parts is.increased one-third. What we claim, and desire to secure by Let In combination with the pinion I, rotating in a fixed bearing in the frame, and a drivingwheel provided with gearing G and H, the

lhand-lever F andeccentric journal D, adapted to move the driving-wheel forward and back- Ward, so as to bring either of the'said gears G or H into engagement witht'he. said pinion or equidistant't'rom it and out of gear, substantially as described.

To the above specification of improvement in harwesters we have signed our hands this Sthof April, 1865.v
