SPECIFICATION forming part of Letters Patent No. 251,986, dated January 3,1882, Application filed January 2, 1880. Renewed Octobir 6, 1881. (Model) Patented in England December-8, 1879.

'To all whom it may concern;

Be it known that 1, WILLIAM Anson Woon, of Youngstown, State of Ohio, mechanical engineer, have invented certain new and useful Improvements on Harvesters; and [do hereby declare that the following is a full, clear, and exact description of the same.

Each one of thesev'eral parts of my lllVQlltion relates to a combination of devices which to is hereinafter more particularly described and set forth, the object of my inventionbeing to better regulate the distance of the front edge of the platform from the surface of the ground, set the uppersurface of the platform at any desired incline, and efl'ecta lowering or elevating of the same from i the drivers side of the machine.

In the drawings, in which the same letters of reference indicate like parts, Figure 1 rep- 2o resents a side elevation of the harvester embodying the improvements of my invention. Fig. 2 represents a plan view ofthe same. Fig. 3represents a plan view of the rake-head and devices operating the same. Fig. 4 represents a. sectional view of the hub of the drive-wheel and locking device for locking the drive-wheel with the gear driving the rakehead. Fig. 5 is the ratchet-wheel with whichthe device shown inFig. 4operates. Fig. 6 is a view of the machine from the rear. Fig. 7 represents a view of the machine,vicwed from the platform side, with platform removed. Fig. 8 represents the grain-wheel and devices for elevating and tilting the platform from said grain-wheel.

'In the drawings, A represents the main frame. B is the draft-pole attached to said frame.

O is the drive-wheel, loosely mounted on axle 0 (1, (shown in Figs. 1, 2, 4, and 7,) which axleis supported in proper .bearings from the main frame A.

D is an internal gear, cast solid with the sup porting-wheel, or attached to the same, which 5 internal gear gives motion to the spur-pinion E, Figs. 1, 2, and 7, which spur-pinion isl-oosely mounted on spindle b, Fig. 7, secured to the main frame A. In the head end of said spurpinion E i'sprovided aratchet-wheel. Loosely mounted on the same spindle b is the bevelgear F, Figs. 1, 2,6, and 7, the said bevel-gear carrying a dog or pawl which operates with the ratchet-wheel carried by thespur-pinion E. When tb us arranged, the drive-wheehwhcn revolved forward, will give motion to the spurpinion E, which spur-pinion will, through the medium of the ratchet and pawl, givemotion to the bevel-gear F; but when thesaid drivewheel is revolved in an opposite direction the said bevelgear' will remain idle.

c is the crank-shaft box, made solid with the frame A, or attached to the same, which crankshaft box carries the crank-shaft d. i To the upper and rear end of the said crankshaft is secured the bevelpinion e, which be-velpinion receives motion from the gearF. To the lower and forward end of said crank-shaftis'secured the balance-wheel f, which carries the pitmanconnection or crank for operating pitman g,'t0

transmit motion to the sickle or knife bar 71. of the machine.

Loosely'secured on axle a of the supporting- Wheel 0 is the sprocket-wheel G, which communicates motion to the rake-head through the medium of the endless chain 1' and sprocket- 7 wheel G, as shown in Figs. .1, 2, and 7. One of the spokes j ofthe supporting-wheel G is made with .a sleeve, is, running "transversely with said spoke, as shown in Figs. 2 and 4. Through this sleeve works a shaft, I. To the outer end of said. shaft is secured a handle, at, and to the opposite end is secured the cam n. V livoted to ears made with the hub of the supporting-wheel is the dog 0, which runs back to the sprocket-wheel G, and engages with the teeth of anvinternal ratchet-wheel, 19, made in said sprocket-wheel G, as shownin Figs. 2 and 4.

A spring placed between dog 0 and the hub of the supporting-wheel throws said dog up, so that its end will engage with the ratchetwheel 9c in the sprocket-wheel G. When the handle at is turned in a direction transverse to the direction of spokej the dog 0 will engage with the ratchet-wheel of the'sprocket-wheel G, and the said sprocketwheel will be revolved by the 5 drive-wheel, when in motion, in a forward direction. When the handle at is turned. back and inadirection parallel with the spokej the cam 92 on shaft l will be turned down on the dog 0, to depress the same and throwits free I00 end out of engagement with the ratchet p of the sprocket-wheel G, when said sprocket wheel will remain idle.

Arranged parallel with the side of the main frame toward the platform H is the tilting frame I, Figs. 1, 2, 6, and 7, which tilting frame carries the platform H and its sickle-bar and guards and the rake. The forward end of the said tilting frame is supported by the eccentric J and its rearward end by the tilting shaft K. The eccentric J is fixed securely to shaft 0, on which the drive-wheel revolves, and works in the flanged way a; an, made solid with said tilting frame, as shown in Figs. 1, 2, 6, and 7. Firmly secured to the opposite end ot'shaft a,

- and-directly opposite the platform M of the drivers seat L, is the worm -gear wheel N. Workingin said worm-gear wheel is the screw P, which screw is provided with a crank, Q, extending up vertically to near the plane of the drivers seat. When the crank Q, is revolved in one'direction the screw P will also be revolved, and will operate with the worm-gear wheel N and revolve it forward, and carry with .it the shaft to of the drive-Wheel, and also the eccentric J, attached to the opposite end of said shafn When the said eccentric is thus moved its throw from the shaft will be downward, and in such a manner as to cause the eccentric to revolve in the flanged ways was of the tilting frame and depress the forward end of thesame, and carry with it the platform H, with its sickle-bar, and also the rake-head. A reverse movementof the crank q will revolve the screw P in an opposite direction, and so operate the worm-gear as to carry the eccentric J upward, so as to carry the tilting frame up, and thereby elevate the platform and rake to a higher plane.

The tilting shaft K, for elevating or depressing the rearward portion of the tilting frame I, extends across the rear end of the main frame A, and is supported in hearings in the same, as shown in Figs. 1, 2, and 6. The end of said tilting shaft next to the tilting frame I is provided with a crank, q, the end of which crank works in slot r, made in the rear end of said tilting frame, as shown in Figs. 2, 6, and 7. Secured to the opposite end of the said tilting shaft K is the hand-lever R, which carries the finger s and elastic dog 8, as shown in Figs. 2 and 7. The dog 8 works in a segmental toothrack, I, and operates to hold the tilting shaft posite direction and elevate the rear end of K in any position it may be set to. When the hand-lever R is thrown forward the tiling shaft will be moved in a corresponding direction, and thecrank q of said tilting shaft will be thrown downward at its free end, and carry with it;the rear end of the tilting frame 1. A reverse movement of the hand-lever R will move the crank q of the tilting shaft in an opthe tiltingframe. When the eccentric J has been operated to carry its greatest throw downward the tilting frame will be depressed, and will carry with it the guards and sickle-bar attached. to the front of platform H, and when in this condition it is desired to give to the platform but a slight inclination, the hand-lever B is to be moved forward, when the crank ofthe tilting shaft will be thrown downward,

and will carry with it the rear end of the tilting frame I, and consequently depress the rear end of the platform H, and thereby cause the platform to have its upper surface about on a plane parallel with the surface of the ground, or to a greater or less angle with the same, as may be selected, accordingly as the rear end of the tilting frame is moved by the tilting shaft.

Secured to the machine from the main shaft or of the drive-wheel and the projecting end of spindle 1) (shown in Figs. 2 and 7) is the depressing-way T.

Pivoted to the platform H, at its lower side,

is the shaft to, held in proper bearings secured to said platform, as shown in Fig.6. The end.

of said shaft toward the tilting frame is provided-with a right-angular piece forming lever to, which lever is provided with a grooved head, a, which receives the lower side edge of the depressing-way T, as shown in Figs. 2, 6, and 7.

Made with the end of shaft a, next to the grain-wheel U, is the crank 12, Figs. 2 and 8,

which crank works in the grain-wheel arm or lever V, hinged to the platform H at a point rearward of said grain-wheel, as shown in Fig. 8.- The spindle of said grain-wheel U is secured to said lever V. The said lever is held in place by the guide w, secured to said plat.- form and clasping the said lever at a point forward of the pivot by which it is connected to the platform. When the rear end of the tilting frame 1 is depressed the platform H, in its rearward portion, will also be depressed, while thegrooved head 0 of lever u of shaft to will ride on the lower side of the depressing-way T, and the crank v of shaft a will be thrown upward, and thereby carry upward the spindle of the grain-wheel U, when the rear end of the platform will be depressed on thegrainwheel side, correspondingly with the rear end of the same at the tilting-frame side, so that both sides of the platform will be on the same plane. I

'A draw-rod, b, connects the pole B to the platform H by means of stud a, secured to the pole,-and stud a secured to said platform, as shown in Figs. 1 and 2. A stiffening-rod, 0, having one end connected to stud a 011 the platform and its opposite end to the tilting frame I, stifiens the connection of said platform with said tilting. frame. v

v Secured to the forward portion of the tilting frame .1, Figs. 6 and 7, is a bracket, A, which bracket supports shaft B, supported in suitable bearings from said bfacket in a position nearly vertical to the plane of platform H. The

IIO

said shaft, which is free to revolve, is made to turn in its bearings by the bevel-gear O, actuated by .thebevcl-pinion D, secured to the shaft carrying the sprocket-wheel G, and supported esnose: v 3

-nearly horizontal and on a higher plane than its opposite side vertical portion, 2, toward the platform side, while the portion 3 of said track will have a gradual descent from the horizontal portion 1 toward and to thevertical portion 2,

to and the rearward portion, 4, will have a sudden rise from the vertical portion 2 to the horizontal portion 1, asshown in Figs. 2, 3, and 6.

.The rake-arms F! are hinged to the headpieeeE by means of the metallic arms F Each metallic arm is provided with aroller,z,which rollers, when the rake-head E is revolved, will revolve on the faces of the several portions, 1, 3, 2, and 4, of the cam-track and cause the rakearms and their rakes to be successively elevated and lowered. The said rollers are arranged nearly at right angles with the metallic arms F so that when they are brought to revolve on the horizontal portion 1 of the cam-track the rake-arms will be elevated, as in Fig. 6,

2-5 and when they are carried forward and descend on the forward portion, 3, of the track the said rake-arms will be graduallydepressed,so as to cause the rakes H to work against the standingj graiirand carry it toward the platform,

0 while when the roller of an arm passes rearward and against the vertical "portion 2 of the track therake will sweepthe platform clear of the accumulatedcut grain thereon and throw itrearward of the platform. When'the said 3 5 roller passes entirely to the rearlportion, 4, of

the cam-track thelsuddenincline of said portion 40f the trackwill cause the rakearm to be elevated the same as w hen first startrd.

-Su1')portedfrom the side of the continuous to cam-track. J toward the platform. H, and from the vertical side portion, 2, of the same, is the bracketlK, provided on its uppersidewitha way, which works the sliding piece, L Fig.3, which sliding piece carries a section, 5, ofthe heater-track. Theinner facefside', m, of said sliding section'o of beater-track is so formed that: when the rollerle of a rake-arm passes be-' tween the said face on and the vertical portion 2 of the continuous cam-track J the rake-arm 5o willbe locked. down from all'liability ofjump' ing upward. The outer side face, 02, of said sliding section 5 is so formedas to run from a vertical line of surface :to one which is oblique or inclined, so that when the saidsliding section5 is. moved back against the vertical portion 2 .ofthe cam-track J, asindicated by dot ted lines in Fig. 3, thexroller z of a rake-arm will move against said face a of said sliding section 51an'd cause the rakearm to be gradir 6 0 ally elevated. i l i Cast solid with bracketK is a fixed section,

6, of the beater track, the face of which is so formed that the roller 2 of a rake-armrevolving against-the sajme'will force the rake-arm aipward to a higher elevationthan when mo'v heaters and rakes, I

'ing against the face side it of the tion 5.- k

'Pivoted from'ears 19, Fig. 3, made with the base portion of the continuous cam-track J, is the switch-track 7, whichforms a section of the beater-track and 1e ids the roller 2 of a rakearm from the sliding section 5 and fixed sec tion 6 to the main continuous cam-track J, so as to raise the rake arm to its highest elevation. When the sliding section 5 of the beatsliding secer earn-track is moved off from the vertical seci tion 2 of the continuous cam track J, as shown by full lines in Fig. 3, the rollers z of the rakearms will move successively against thefaces of the portions 1, 3, 2, and 40f said cam-track and cause the rakes (as they are continuously revolved) to alternately rise and descend tion 5,- the rakes, as they are revolvedbythe head-piece E, will besuccessively elevated and depressed for operation asbeaters to carry the standing grain toward the platform, butnot for operation as rakes to sweep theplatforin clear of the fallen grain. To effect an automatic movement of-the sliding section 5 of the beater-track toward and from the main and continuous cam-track J, for causing the rakes to operate alternately as provide the followingdevices and mechanism: i

Made with thelower side of the-headpiece E (shown in Fig. 3) are one or more downwardly-prqjecting pieces, g, which pieces revolve with said head-piece continuously. Secured to the upper end of a vertical pivot work ing in a bearing made solid with the camtrack J is the lever-arm r. (Shown in thesaine figure.) Secured to the lower end of thesame I vertical pivot is another lever, 01:, which lever 1 is connected by connecting-rod a to another lever, 3 (shown by dotted linesin Fig. 3,) arranged below the sliding piece L, and secured to the lower end of the vertical pivot z of a tripping-lever, 0 The lever 31 is yoked to a sliding latch, 0 (shownby dotted linesrin Fig. 3,) which sliding latch works in the lower side of the sliding piece L, and is provided with a holdingJip on its head end toward the continu ous cam track, and is adaptedto engage with the head end of said sliding piece L. The/vertical 'pivot% to which the levers or arms r and r are secured is made with a greater length than the length of the bearing in which said vertical pivot works, and is made elastic by a spring, (not shown,) which spring so operates IIS with the said pivot and its attached lever-arms as to hold the lever 1" up to a plane on a horizontal line above the lower ends of the downwardly-projecting pieces q q, carried by the head-piece E. A spring, s Fig. 6, is provided on the lower side of the sliding piece L, and connecting from the head end of the same to the outer end of the bracket K, for the purpose of drawing the sliding section 5 of the beater-track to the vertical section 2 of the continuous cam-track J.

Supported from the bracket supporting the rake head shaft B is the bracket-arm d which carries a crank-shaft, f Figs. 2, 3, and 6, supported in suitable bearings. Made with the end of said crank-shaft toward the rake-head is the arm 9 which rests on'the heel of lever 00. (Shown by dotted lines in Fig. 3 and full lines in Fig. 6.) Pivoted to the outer arm crank end of shaft f is the draw-rod [1, which connects in a pivoted manner to the short end of the foot-lever m having for its fulcrum the outer end of the shaft a of the supportingwheel 0, as shown in Figs. 1, 2, and 6.

The manner in which theseveral parts of this mechanism operates is as follows: VVhen' the head-piece E is revolved continuously by the mechanism provided the downwardly-projecting pieces g on said'head-piece Will strike on the inner side edge of the lever-arm r, and so press on it as to cause it to turn outward, when the'lever m below, secured to the same pivot, will also be moved outward and draw, by the connecting-bar 00 the lever y in the same direction. This movement of the lever y will be in a direction toward the continuous camtrack J, and being secured to the vertical pivot z of the tripping-lever a will cause the free end of the said tripping-lever c to be moved toward the said cam-track. The lever y, when moved toward the cam-track, will, by reason of its being yoked to the sliding latch 0 carry said sliding latch forward and throw its catching head end in engagement with the lower side of the head end of the sliding piece L, which carries section 5 of the beater-track, while at the same time the said sliding section 5 will be carried by spring 8 up to the vertical section2of the continuouscam-track J. When the several parts are in this position the tripping-lever will be partially over the groovetrack of the rollers z of the rake-arms, so that when the head-piece E is made to continue its revolution, and the projecting piece g has been carried past the lever r, the latch-piece 6 will be set for operating the sliding piece L to move it back and carry the sliding section 5 of the beater-track 01'1" from the main cam-track J, to permit therollerz of the first approaching rakearm to pass between the vertical section 2 of I the cam-track and the face m of said sliding section 5. This movement of the sliding piece L and its section 5 of the beater-track is effected by means of the roller 2 of the first ap-' forward movement, press against the tripping lever or arm 0 and force it to move outward, and by means of its vertical pivot z,to which it and the lever 3 beneath are secured, the said lever y will also be moved outward, and will carry with it the latch-piece e engaging with the sliding piece L, and draw said sliding piece and section 5 of the beater-track with it from the cam-track, when the roller 2 of the said approaching rake-arm will pass between the face m of the said section 5 and the vertical facesection 2 of the cam track J, and the rake attached to the said rake-arm will be depressed,

and will be made to sweep over the entire surface of the platform and clear it of the cut grain fallen thereon. As soon as the roller 2 of the said rake-arm has passed out between the said two sections 5 and 2 another-projection, q, made with the head-piece E, will operate with the lever r to reset the several parts for another operation.

When four rake-arms with rakes are employed lose two project-ions, q, one situated opposite to the other, as shown in Fig. 3, and

thereby secure an alternate rake and heater movement'of the rakes, which are adapted to be thus used alternately in good or heavy grain. When thegrain is light in its straw, and it is desired to have the machine travel a greater distance before discharging the cut grain from the platform in bunches, the driver will with his foot press on the foot-lever m when said lever will operate the crankshaftf and cause the arm 9 to press on the heel of lever 40, and thereby carry said lever, together with the lever 1*, downward, so that the upper surface side of said lever 1" will be carried below the I plane of the lower ends of the projections q q, carried by the head-piece E, when the said projection will pass free from contact with lever 1", when said lever will be unaffected, and consequently the sliding section 5 of the beatertrack -will be held up to the vertical face-section 2 of themain track by the force of the spring 8 in Fig. 6, and not by the sliding latchpiece 6 as before described. Inthis condition of parts the rakes will be revolved only as heaters, and will not operate as rakes for sweeping the platform clear of grain, as the rollers 2 will revolve against the face n of the sliding section 5 of the beater-track, and not between said section and the vertical face-section 2 of the main cam-track; but when the driver removes the. pressure of his foot from lever m the projections q q will operate against the lever 1", which will be carried upward by the spring before referred to,to give movement to the several parts operating to. set the sliding latch-piece e and tripping-arm c, when the rake-arms will revolve and be made to operate the rakes alternately as heaters and rakes.

What I claim, and desire to secure by Letters Patent, is-

1. In combination with the main frame A and with the tilting frame which carries the platform and rakes, the eccentric J adapted to operate directly upon the said tilting frame, said eccentric being fixed on the shaft a, on one side of the main supportingwheel, and
