IMPARQVEMENT IN HARVESTING-MACHINES.

Specification forming part of Letters Patent No. 16,131, dated November '25, 1856; Reissue No. 1,203, dated June 25, 1R61. l

To all whom, t may concern:

, Be it knownthat I, XVILLIAM N. WHITE- LEY, Jr., of Springield, in the countyof Clarke and State of Ohio, have invented various new and useful Improvements in Harvesting-lNIachines', and I do hereby declare that the following is a full and 'exact description thereof, reference being had to the accom- Ipanying drawings, and to the letters of refercomposed (mainly) of old parts improved intheir construction and manner of arrangement in respect or relation to eachother, for obtaining both fthe combined as well as the separate functions-of the various parts of which a i harvesting-machine is composed in a more advantageous manner than they were attained previous t0 my invention.

kTo enable those skilled in the art to-.make and use myseveral improvements forming the subject of this division, I will now proceed'to .describe them and the -advantages obtained by them as I have practiced them, referring by letters and figures to the accompanying drawings, forming part of this specification, in which- Figure 1 illustrates in perspective a harvesting -machine embracing my improvements.

Fig. 2 represents a perspective view of one of the sector-plates @which carry the adjustable boxes in which revolves the axle of the.

main ground and driving wheeDand its center stud or bearing detached. Fig. 3 represents a' detached perspective of pinion-shaft, pinion-clutch, and shipper. Fig. trepresents a vertical longitudinal section through the Fig.'5 represents a vertical longitudinal section inside of the main driving-wheel, illustrating more fully Ithe vibrating adjustable sector-plates and adjustable shaft or axle-boxes. Fig. 6 representsa.

Fig. 8 represents a perspective view of connectingcasting. at the line 4, 4t of Fig. 4. perspective views of tongue-heel and holding or retaining stirrup. view of rake-arch balance-lever, &c.

Similar letters denote the same parts in the different views.

A and A2. represent the two beams of the main ground-wheelframe. That of A is somewhat larger and extends fartherforward for receiving the tongues retaining-stirrup. y

A is a cast-iron connecting-piece, by which and screw-bolts at the front end of A2 the beams are connected together.

' G is an extension-bar, with a single screwrbolt passing up throughit and each of the beams, neartheir rear ends,whereby they are sustained above it in a very secure manner, so that any shrinking of the beams can be overcome by merely tightening the nuts on the bolts. A

Extension-bar G', after extending out from beam A the proper distance, has a downward set or bend in it, from near which bend its extended part forms the nger-bar G, on which is arranged, in the usual. manner, the cutting apparatus, of which the fingers O only are shown. n is a brace-rod, the rearend of which is connected to the under side of the bar G near its bend, and its front end` to beam A, by the bolts O3, which connect the heel of the tongue B to beam A, which brace-rod and the connecting-casting A', together with the extension-bar G, retain the frame against being forced out of square or in twist. r

In beam A there are two holes, 0 and O2, and may be more, one abovethe other, for bolt O3, for rendering the heel of the tongue vertically adjustable, as is required for Aenabling the attendant to give the finger-bar a heavy or light bearing on the ground, or keep its bearing the same, when the height of the front of the frame is varied when mowing, and the tongue the same, or vary its angle to that of the frame when reaping, and to the front end of which beam A is secured the tongues re- Fig.'9 represents a vertical section Fig. lrrepresents Fig. 7

Fig. 1l represents side I taining-stirrup vT, by which the tongue is rel shipper y, by which pinion b is thrown in contained, and in which it plays freely up and down when the machine is used for mowing, and against the upper end of which stirrup it is held by the drivers weight when in his seat, when used for reaping, which makes the heretofore limber tongue for mowing a rigid one for reaping. i l

e is the box in which the master-wheel pinion-shaft E revolves, and from the end of which, through the proper gears and a crank and pitman, (not shown,)the cutters (also not shown) are vibrated or reciprocated, which is confined to the upperedge of beam A and covered by a corresponding box, each of .which extends over the beam toward beam A2.

f and f2 are the sector-plates, with a large hole in the small end of each and a series of small holes in their large ends, lying in an arc the center of which is the center of the large holes, and also an inward-projecting flange on the upper edge of each, with two holes, s s, in

, each, and a projecting lip on the inner side of f, in which is placed the fulcrum-pin of the shipper q, by which pinion?) is thrown in connection with its clutch-pin, which parts rfo'rm my improved .sector plate or plates, as set forth, which have two novel and useful features-a top flange for receiving theadjustable boxes, whose place may (in some instances) be supplied by 1n ak-ing holes for the main groundwheel axle at various distances from its pinionshaft, and a lip for the shipper qs fulcrumpin, which makes a cheaper and much more rigid fulcrum for the shipper than if made separate from the sector-plate.

r is pinion bs clutch pin, which passes 'through shaft E, between its pinion, when on its shaft, and box e, for coupling them together and puttingV the cutters in motion, as set= forth, which improvement is one which will. be seen to be very useful, from the fact that*` the hole in the shaft into which the clu tch-pin is placed is reamed out on the outeredges and the pins ends upset therein, which makes itV very tight in the shaft, and the projecting ends larger, which could not be done when itV has to be removed for changing pinions.

The shipper-groove in the hub WV (see Figs. I l and 3) and also the clutch-pin slot 2 (see Fig. 3) in the end of the hub of all the pinions to be used on shaft E must beA made the; same size, so that the pinions will differ only in their size and in the number of their cogs. The small end of the sector-plate f is hung and Vturns on the projecting end of box e, and

that of f on a short stud, M, (seen at Fig. 2,)

when attached to beam A2, in line with shaft E, with their rear ends each attached to its beam by a screw-bolt passed through one of the series of holes, the same one in each sector, and its beam which confines the frame to `the sectors, so as to be at the desired distance from the main ground and master-wheel axle, which distance may be varied by the attendant by placing the screw-bolts in a different vone of the series of holes. The forked end of a little in front of the finger-bar.

nection with its clutch-pin r, for putting the lcutters in motion, and by which (alone) the pinion b is retained on its shaft E, is now placed in the groove in hub W andon its fulcrum-pm. Y

C is the main ground and driving wheel. a3

are its arms; a2, its internal cog-rim; a, its internal gear; C, its convex connecting-plate, which connects the `edge of the internal cogrim, a2, with the edge of the ground-rim C, and projects farther out than the edge of either or the cogs a, for causing the wheel to run 4with rless power applied, protecting the cogs,

and for preventing the thin edge of the rim from carrying up the earth and dropping it on the working parts. f

U is the hub ofthe main ground and driving wheel, and D its axle. g g are the adjustu able boxes in which it revolves, and in which are formed longitudinal slots i i, through which passrthe bolts h h into the lioles s s in the nanges of the sector-plates ff, for confining said boxes at such various distances from the master-wheel pinion-shaft as will bring the gear c properly in mesh with al1 the varioussized pinions to be used on said pinion-shaft, which changes are fully illustrated by red and black lines at Fig. 6 of the drawings-the small pinion b and pitch-circle'cin black and the large pinion b2 and pitch-circle c2 in red.

, lt will now be observed that the main ground-wheel frame can be raised nearer to or lowered farther from the axle of the main ground and driving cog-wheel., and also the axle brought nearer its wheels pinion-shaftl (which always occupies the same position 011 the frame) or removed farther from it, for

vbringing gear c in mesh with whatever sized pinion will give the cutters the desired number of reciprocations or vibrations. Thus it will be seen that any desired number of vibrations or reciprocations can be given to the cutters by using the proper-sized pinion and varying the distance between the master-wheel axle and its pinion-shaft to suit the pinion used, and also that the distance of the frame from the axle can be varied when desired.

Now, it will be observed that my machine,

with the attachment of a dividing-point and,

swath-board to the endV of the finger-bar farthest from the wheel-frame, which I' shall hereinafter call the outer end, is ready for from t-he finger-bar and platform, and attached to the outer end of the finger-bar by a single screw-bolt. y H is the grain-wheel, attached to the divider Y p N is the reel-post; O andV R, reel-braces. The reel is notshown.

Bis the platforn1,which is made separate from vits clutch-pin has two and secured (the Awide end) to the under edge of that part of the divider in rear of the finger-bar by screw-bolts, and the narrow end to the rear ends and under edges of beams A and A2 by a screw-bolt in each.

K is the rake-arch, curved to suit the circle the rake makes in its raking stroke, with its front end about the same width to or near where the rake-head leaves the platform (when its front end is placed about over the rear end of bracea'od n., edge upward on the circle the rake moves) in its raking stroke, from which place its upper edge inclines upward a sufficient distance for raising the rake-teeth out of the gavel which they are discharging without 'entangling it, and from there backward it inclines a little downward for retaining the rakehead at rest when a gavel of suicient size is not formed at one revolution of the main ground-wheel. To the curved side ofthe rakearch is attached (by a fulcrum-pin) the forked balance-lever P, with a weight, P, at its lower end, which lever is checked in its vibration by its stop w.

F is thev rake-head, with its inner or center end connected to the upper edge of beam A2 at i* by a link or universal joint. f2 are its teeth, which occupy nearly the space between its arch and its outer end. Y

@"is the crank by which the rake is driven, on the inner side of the large end of which is a hub in which is cut a shipper-groove, and in the outer side of which .is cut a clutch-pin slot.

0n the extended portion of axle l) is placed a coiled spring, which, when crank Z is placed on the outer end of axle D and a clutch-pin through the axle after the crank is on it near its end, always holds the crank in clutch with when not held out by its shipper P, the forked end of which ts' into the groove in the hub of crank e.

, M is the pitman by which the motion of crank i is transmited to the rake-head, the large end of which pitman surrounds the wrist-pin in the small end of the crank, and the fiat end of which passes through a slot in the rake-head, and is there confined by a pin, c2,

L is the driver s seat on its outward inclined leg, L2, which is attached to the connectingcasting A by screw-bolts, so that it can be readily removed for using the machine as a mower, by which manner of attachment it separate anddistinct functions, the first of which is the raising and retaining above the ground the rear end of the wheelframe and making the heretofore limber tongue a rigid one bymerely placing the driver on his seat, (his weight bringing the top of the stirrup T down on the tongue,) as set forth in recital eighth; and it will further be observed that to perform the last-mentioned function the drivers seat has no occasion to project outside of the Wheel-frame; and, also, that by having it project outside, as shown and del scribed, the drivers weight, when in his seat, peforms an entirely new function-that of rais- V1,203 I p 3 ing and preventing the sag in the nger-bar, as well as that of raising and retaining the rear end of the wheel-frame, by which arrangement the machine is given more power, the side draft diminished, and the entire 1nachine caused to run lighter; audit will bc still further observed that, were the self-rake removed and a man placed on the wheel-frame for removing the gavels, the attachment-of my adjustable drivers seat, as described, would perform the same functions as with a self-rake, and therefore I do not wish to limit its use to a combined self -raking reaper and mower, the design of placing the drivers weight in a certain position in relation to the bearing of the main groundwheel on the ground being for accomplishing the hereinbeforedescribed advantages, and not the peculiarmanner of so placing it. It is obvious that it might be made to occupy the same position connected to the frame in a different manner than that practiced by me, which I have found to work well.

The operation of my improved self-raker for harvesting-machines is as follows: Suppose a sufficient quantity of cut grain on the platform for a gavel, the rake-teeth just dropped into the butts thereof by the weighted lever l?, which carries the'rake forward over the cut crop,

and the crank i just passing its dead-center in front (as the machine moves forward) and moving the rake backward and from the standing crop, (the teeth in an arc,) and the head parallel with the platform to or near its rear edge, and from there up the incline of arch K, by which movement the rake-teeth are raised out of the gavel, being discharged by them without entangling it-a thing which could not be done were there [no incline arch or its equivalent for raising the rake-teethout of the gavel at about 'the time it leaves the'platform. This feature aloneof my invention is of great value, were Vthere no other functions performed by my improved selfrake, and therefore the parts which produce said movement will be claimed in a separate combination from those which perform other functions. f Y

Ther second distinct function of my self-rake will be seen in the points of the teeth, which teeth move in an are over the platform, the center of which is farther from the standing crop than the platform, moving faster than their other end, by which movement the teeth, when starting the gavel from the platform, are less liable to breakage on account of their points standing forward a little, which permits them to slip in the uncut grain, (should they engage with it,) and, when leaving the gavel and platform, be at different angles to them than when starting the gavel, and by which also, the gavel leaves them more freely without becoming en,- tangled by them than it would otherwise do.

The third function of my improved self-rake will be seen in the rake moving in an arc the center-of which is farther from the standing crop than the platform, and inreasingin Nelocity from where the teethy enter the gavel to about Where they leave it. By this arrangement the liability of the rake to be broken by talaring` hold of the tangled uncut erop isA entirely prevented, which is a great desideratum 'and one of the main features in my self-rake.

Having thus fully described the construef tion and operation of those parts or functions of my invention claimed inv this division, what I claim as my invention, and desire to secure by Letters Patent, is

1. In combination with the main ground- Wheel frame of a harvesting-machine, the sectorplates f f', provided with the adjustable boxes g g', or their equivalents, substantiallyv as shown and described, for the purposes specified. 4

2. In combination with the sector-plate f, a projecting lip for the shippers fulcrum-pin,

` substantially such as shown and described, for

the purposes specified.

3. Retaining the pinion on itsshaft by means of the shipper or its equivalent, by which said pinion is thrown in and out of connection with its clutch-pin, substantially as shown and described, for the purpose stated.

4, Soconnecting or combining the drivers f seat of harvesting-maehines with the front end of the frame of the same (when used for reaping) that when the driver is on his seat his weight will do either, raise and hold up the rear end of the wheel-frame (to which the cutting-up harvesters are connected) or both the rear end of the frame and the center, of the iinger-bar, for the purposes specified.

In testimony whereof I have hereunto set my hand this 19th day of March, 1859.
