IMPROVEMENT IN HARVESTlNG-MACHINS.

, Specicationforming part of Letters Patent No. 16,131, dated November 25, 1856; Reissue No. 1,203, dated June 25,1861 Reissue No. 1,6l4, dated February 2, 1864.

"of my invention, asa whole, being to produce a harvesting-machine which will operate both as a mower and self-raking reaperl with the fewest changes (attachments or detach ments) possible.

The nature ot' my invention consists` in the combination ot' the main frame ot'a harvesting-machine with the main ground and driving wheels pinion-shaft on the frame, with sector-plates and sliding adjustable boxes so constructed `and arranged that the attendant of the machine can both vary the distance of the frame from the axle of the driving-wheel (so as'to carry the frame higher or lower) and its distance from the pinion-shaft (to suit-differentsized pinions) while the axleot' the driving-wheel remains in the boxes in which it turns; second, making a projecting lip on the sector plate above mentioned for the fulcrum-pin of the shipper, which traverses the pinion heretofore mentioned; third, retaining the pinion on its shaft by means ot' the shipper, which throws it in and ont of connection with its clutch-pin; fourth, so, connecting or combining the drivers seat of harvesting-machines with the frontend oftheframe ofthe same (when used for reaping) that when the driver is on his seat his weight will either raise and hold up the rear end of the wheel-frame (to which the cutting apparatus is connected) or both the rear end of the frame and the center of the finger-bar.

To enable those skilled in thc-art to make and nsemy several improvements forming the subject of this division, I will now proceed to describe them and the advantages'obtaincd by them, as -I have practiced them, referring by letters and figures to the accompanying DIVIsIonA,

l drawings, forming part of this speciticatioinin which- Figure 1 illustrates in perspective a harvest` ing-machineemhracingmyimprovemcnts. Fig. 2 represents a perspective view of oneV ot' the sectorplates (which carry theadjustable boxes in which revolves the axle of the main ground and driving wheel) and its center stud or bearing detached. Fig. 3 represents a detached perspective of pinion-shaft, pinion-clutch, and shipper'. Fig. 4 represents a vertical longitudinal section through the center of the main driving-wheel. Fig. 5 represents a vertical longitudinal section inside of the main driving-wheel, illustrating more fully the vibrating adjustable sector-plates and adjustable shaft or axle-boxes. Fig. 6 represents a partial duplication of Fig. 5, illustrating by red and black lines the change ot' pinions by sliding the master-wheel axleboxes. Fig. 7 rep- `rcsents a vertical cross-section of the master or main ground and driving-wheel.

Fig..8 represents a perspective view of a connectingcasting. Fig. 9 represents a vertical sect-ion at the linc w of Fig. 4. Fig. 1() represents perspective views of tongue, heel,and holding or retaining stirrnp. Fig. 11 represents a side view of rake-arch or guide balance-lever, &c.

Similar letters denote the same parts inv the dierent views.

A and A2 represent the two beams of the main ground-wheelframe. That ofA is somewhat larger and extends farther forward for receiving the tongues retaining-stirrnp.

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 extensioI1-bar,with a single screwbolt passing up through it and cachot the beams, near their rear ends, whereby they are sustained above it in a very secure manner, so

that any shrinking of the beams can beovercome by merely tightening the nuts -on the bolts., The extension-bar G', after extending 'out-from beam A the proper distance, has a downward set or bend in it, fromtnear which bend its extended part forms the finger-bar G,

onv which. is arranged in the usual manner the `cutting apparatus, of whichthe tingers 0 only -are shown. 1 u .f N is a brace-rod, the rear end of which 1s 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 ofthe tongue B to beam A,which brace-rod and connectingcasting A', together with the extension-bar G'. retain the frame against being forced out of square, or in" twist. ln beam Ak there are two holes, o and 02, and maybe more, one above the other, for bolt 03,'for rendering the heel of the tongue vertically adjustable, as is required for enabling the attendant to give the ungerbar a heavy or light bearing on the ground, or

keep its bearing the same when the height ofV 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 ot' which beam A is secured the tongues retaining-stirrup T, by which the tongue is retained, and in which it plays freely np and down when the machine is used for mowing, and against the upper end of-which stirru'p it is held bythe d riverswei gh t, when in his seat, when used for reaping,which makes the heretofore limber tongue for mowing a rigid one for reaping.

eis the box in whiclithemaster-wheel pinionshaft E revolves, and from the end of which, through the proper gears and a crank and pitman, (notl showin) the cutterslalso notshown) are vibratedk or reciprocated, which is confined to the upper edge of beam A, and

' covered by a corresponding box, each ofwhich small holes in their large ends, lying in an` are the center of which is the center of the large holes, and also an inward -projecting flange on the upper'edge ot' each, with two holes, s s, -in each, and a projecting llip on the inner side off, in which is placed the fulcrumpin Vof the shipper q, by which pinion b is thrown in connection with clutch-pin, which parts form my improved sector plate or plates, as 'set forth, which have two novel and useful features-a top flange for receiving the adjustable bones, and a lip for the shipper qs fulcrum-pin-wbich makes a cheaper and much more rigid fulcrum for the shipper than if made separate from the sector-plate.

lr 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 putting the cutters in motion. This improvement is one which will be seen to be very useful, from the fact that the hole in the shaft, into which the clntch-pin is placed, is reained out on the outer edges and the pins ends upset therein, which makes it very tight in the shaft, andthe projecting ends larger, which could "not be done when it has to be removed for changing pinions. i

The shipper-groove in the hub w, (see Figs. 1 and 3,) and also the clutch-pin slot 2 (see Figa) inthe end of the hub of all the pinions to be used on shaft E, must be made the same size, so that the pinions will differ only in their size and in the number of their cogs. l l The small end of the sector-plate fis hung and turns 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 lbeam by a screw-bolt passed through one of the series of holes, the same one in each sector, and its beam, which contines the frame to the sectors, so as to be at the desired distance from the main ground and master wheel axle,

which distance maybe varied by the attendant by placing the screwbolts in a different one of the series of holes. The forked end of the shipper y, by which pinion b is thrown in connection with its clutch-pin r, for putting the cutters in motion, and by which alone the pinion b is retained on its shaft E, is now placed in the groove in hub tu and on its fnl- Acrum-pin.

C is the main ground and driving wheel. a3 are its arms; a?, its internal cogrim; a, its internal gear; c, its curved flange, which connects the edge of the internal cog-rim, 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 with less power applied, protecting the cogs, and for said boxes at such various distances from tbe `master-wheel pinion-shaft as will bring the gear a properly in mesh withv all the varioussized pinions to be used on said vpinion-shaft, which changes are fully illustrated. by red and black lines at Fig. 6 of the drawings, the small pinion b and pitch-circle c in black, and the large pinion bzand pitch-circle c2 in red. It will now be observed that the main groundwheel 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 wheel-pinion shaft, (which alwaysoccupies the same position on the fra-me,) or removed farther from it for bringing gear a in mesh with whatever sized pinion will give the cutters'the desired number of reciprocations or vibrations, all the changes being made without `removin g the axleboxes from the main driving Thus it will be seen cog-wheels shaft or axle. that any desired number of vibrations or'yreciprocations 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, without removing the sliding boxes from the axle. Now,

it willbe observed that my machine, with the attachment of a dividing-point and swath-- board to the end of the finger-bar farthest from the wheel-frame, which I shall hereinafter call the outer end, is ready for mowing, with the addition ofthe cutters, Src., (notshown in the drawings.) I willtherefore remove the dividing-point and swath-board and attach' the adjustable parts which change it into a self-raking reaper. Y

I is the divider, which is made separate from the finger-bar and platform, and attached to the outer end of the finger-bar by a single screw-bolt.

H is the grain-wheel, attached to the divider a little in front ofthe linger-bar. This grainwheel is made will] a wide deep groove on one side, as shown in an additional drawing, Fig.

12, between the hub and rim or tread,land' the pivot on which it turns is fixed in such al position that the sickle-bar or cutter at the end of the bar will traverse into the groove when the -fro'm and secured (the wide endito the under edge of that part of thc divider in rear of the linger-.bar by screw-bolts, and the narrow end to the rear ends and under edges Aofbeams A and A2 by a screw-bolt in each.

K is the rake arch or guide, curved to Suit the circle the rake makes in its raking-stroke, with its front end about the same widtlrto or near where the rake-head leaves the platform in its raking-stroke, from which placeits upper edge inclines upward a sufficient distance for raising the rake-teeth out of the gavel which is falling from the platform without entangling it, and from there backward it inclines aI little downward for retaining the rake-head at rest when a gavel of sufficient size is not formed at one revolution of the main ground-wheel, and the rake-crank is disengaged until sufcient grain has been gathered to form another gavel. To the curved side ofthe rake-archis attached (byafnlcrumpin) the forked balance-lever P, with a weight,

p, at its lower end, which lever is checked in. its vibration by its stop X.

F is the rake-head, with one end connected to the upper edge of beam A2 by a link or universal joint, 4, forming a fixed fnlcrum about opposite or in line with the cutter-bar, on which fulcrum the rake vibrates when its outer end is carried across the platform to remove the gavel, and is then raised up and carried forward over the cut and fallen grain to rake off the nextV gavel, the rake making all its movements with one end fixed at i4. By xing the fulcrum of the rake-head opposite or a little forward of the end of the cutter-bar, the rake moves the gavcl or grain sidewise as `soon as it begins to move it backward. f2 are its teeth, which occupy nearly tire space between its arch or guide and its outer end.

l is the crank by which the rake is driven, ony

the inner side of the large end of. which is a.

hub in which is cut a shipper-groove, and ini the outer side of which is cutaclutch-pin slot..

On the extended portion'of axle D is placed coiled spring, which when crank l 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,) which spring always holds the crank in clutch with its clutch-pin when not held out by its shipper P, the forked end of which fits into the groove in the hub of the crank l.

m is the pitlnan by which theinotion ofcrank lis transmitted to therakehead,v the large end of which pitman surrounds the wrist-pin in the small end of the crank, and the dat end of which passes through a slot in the rakehead, and is there contined by a pin, c2.

L is the drvers seat on its outer inclined leg L?, whichis attached to the connecting casting A by screw-bolts, so that itcan he readily' removed for using' the machine a mower, by which manner of attachment it has two seperate and distinct functionsthe iirst ot' which is the raising and retaining above the ground the rearend of the wheel-frame, and making the heretofore-limber tongue a rigid one by merely placing the driver on his seat, (his weight bringing the top ot' the stixrup T down on the tongue,)as set forth, and it will be further observed that to perform the last- `mentioned function the drivers seat has occasion to project outside of the wheelframe, and also that by having it project outside, as shown and described, the'drivers weight, when in his scat, performs an entirely new-function, that of raising and preventing the sag in the fingerbar, as we llas thatofraisingand retaining the rear end ofthe wheel-frame, by which arrangement the machinc'is given more power, the side draft diminished, and Vthe entire machine caused to run lighter; and it will be 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 thereforeI 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 ot' -the main ground-wheel on the ground being Afor accomplishing the hereinbefore-described advantages, and not the peculiar-manner of so placing it. It is obvious that it might be matie 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 self-im proved self-raker whichv carries the rake forwardv over the cut crop, and the crank ljust 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 of arch K, by which movement the rake-teeth are raised out of the gavel, being discharged by them without entangling i-t-a thing which could not be done were there no incline arch or its equivalent for raising the rake-teeth out of the gavei at about the time it leaves the platform. This feature alone of my invention is of great value, were there no other functions performed by'myimproved self-rake, and therefore the parts which produce said movement will be claimed in a separate combination from those which perform other functions. The second distinct function of my self-rake will be seen in the points ofthe teeth, which teeth move in an arc over the platform, the center of which is farther from the standing cropzthan the platform, moving faster than their other end, by which movement the teeth, when starting thegavel 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 leaviug'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 entangled by them, than it would otherwise do. The third function of my improved self-rake will be seen in the rake moving in an A arc the center of which is farther 'from the standing crop than the platform, and increasing in velocity-from where the teeth4 enter the gavel to about where they leave Y it. By' this arrangement the liability of the rake to be broken by taking hold of the tangled uncut crop is entirely prevented, which is a great 1, The combination of the mainframe of a harvesting-machine with the main ground and driving wheels pinion-shaft onV the frame, the sector-plates f f', and the sliding or adjustable boxes g g or their equivalents, so that `the attendant ofthe machine can both vary the distance of the frame from the axle of the drivingwheel and its distance from the pinion-shaft, while the axle remains in said sliding boxes, in which it revolves, for the purposes set forth and described.

2. In combination with thesector-platef, a projecting lip for the shippers fulcrum-pin, substantially such as is shown and described, for the purposes specified.

3. Retaining the pinion on its shaft 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. So connecting or combining the drivers seat of harvesting-machines with the front end of the frame and the center of the finger-bar, t i' for the purposes specified.
