" ALMON-P. AAYERS, OF CHICAGO, ILLINOIS.

. `IMPROVEMENT 1N HARVESTERS.

Specification forming part of Letters Patent lid-104,407, datedY J une 2] 1870.

To all whoml 1i-may concern.-

Be it known that I, ALMON P. AYERs, o

Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Harvesters 5. and do declare that the following isa true and accurate descrip- .tion thereof, reference being had to the accompanying-drawing, and 3to thefletters of reference marked thereon, and being a part of this specification. f The natureof this invention relates to an improved construction of harvesting-m achines. It consists in the combination of the devices for giving a reciprocating motion tothe rakehead ,the arrangement of the rake-head upon the platform; the combination of the devices for raising the grain when cut, and for binding it; the arrangement upon 'the platform of the "devices for .holding thebinding-rope, and for cuttingitoif as needed; also, in the general arrangement of its various parts, as more fully hereinafter set forth.

Figure l, Plate 1,=is aplan view of my looking from the front, to show-the operation l of the elevator. Fig.` 5 is a bottom plan of the loop in which the elevatin g-strap travels, and

which `releases its catch, allowing the elevator `to drop. l Fig. 6 is adetached elevation-of the reciprocating rack which-v` operates the rake, looking at it from the front. Fig. 7 is an elevation of the cam which reciprocates the sicklebar. Fig. 8 is a cross-section of the same.

Like letters indicatelike parts in each iigure. y

l In the drawing, A represents the main frame ofthe carriage, in which is mortised or otherwise secured, at one side of the center, a pair of sills, vA1, extending from front to rear. Between these sills the traction-wheel B is placed, its shaft rotating in suitable bearingsy `in the` sills.` At the grainside or end ofthe frame a carrying-wheel, C, is l so placedas to support that side of thernachine, although the "princil pal weight is supported by the traction-wheel. A2 is the iinger-bar, which is attached at either end to the frame A. On the nger-bar the sickle-bar D is placed, being reciprocated by the traction-wheel through its bevel-gear B', which rotates a short `shaft,E,v through its pinion E'. At the other end of the shaft E is a cam, F, which reciprocates a cani-frame,l F', connected with the sickle-bar byapitman,A D.

G is a reel, one end of whose shaft is journaled in astandard at the' right side of -the frame, and the other in a similar standard rising from a metallic frame, H, extending from the front around to the rvrear of the Amachine over the inner end of the platform or apron I, which is composed of strips of wood or metal l running parallel with the sickle-bar, and sejustable vertically, as shown.

J is a shaft, whose rear end overhangs the l rear partof the frame of the machine, Vcarrying a spur-wheel, J'. .This shaft is rotated by the tractlon-wheelthroughbevel-gears'on each, as shown in dotted lines in Fig. 3. Within the frame a` chain-wheel, K, is secured to the shaft J, which communicates motion toa counter-shaft, L, below,` provided with agchainl wheel, L', by means of an4 endless chain,1la, passing around both. On the rear end of the counter-shaft a spur-wheel, M, is 'rigidly se cured,

N is a bar, provided with rack-teethon ilits upper and `under sides at the rearedges thereof,` which rack-teethfare alternately caused to engage with the spur-wheels J'Vand -M,and

`thus reciprocate the-rack-bar, the alternating engagement of the racks with the pinions fbeing eifected in the following manner: `The in ner or plain part of .the rack-bar is provided `with an opening near each end-of the racks;

ya stud, b, projects from the rear part'of4 the 4jfrain'e between the gears J' and M; a'spring,

c, secured to the frameunder the rack-bar,

presses the-latter upward-as it 4passes along,.- the stud underneath keeping the rack ony its' upper sidein gear with the wheel' Vuntil the :opening at its grain` end is overfthestudb, when it drops down into Vgear with the wheel M, which reverses' the motion,n causing the rackfto movetoward the standing grain, the `stud preventing it from rising until the `opening at the other end reaches the stud, when the spring o throws it upagain into gear with the wheel J', and the motion of the rack-bar is again reversed.

fN' is a bar, securedat itsrear fend to the grain end of the rack-barextending across and underneath the platform I, reciprocating inface of the frame A at the rear of the platform,

the rake-teeth lying horizontal until reaching the inclined plane P', up `which it ascends until it passes the cam-latch e at the end of the guide I), which drops under it. At this time the travel of the rake is reversed, as hereinbe- Y fore described, when it is compelled to move forward on the top of the guide, which causes it to bring the rake-teeth to a vertical position. As it moves toward the inner end of the platform it carries the grain lying there along with it, pushing it off the platform onto an elevator, Q, consisting of a series of hookshaped rods attached to a shaft jonrnaled in the outer ends of the rods Q', whose inner ends are pivoted at f to the main frame.

g is a rock-shaft journaled in the frame under thebinding-platform R. At either end of the shaft is secured a lifting-lever, S, under the elevating rods Q'. The lever, at the rear end of the shaft, is extended beyond the shaft in the form of a sector, S', to the upper corner of which a ilerible metallic or other strap, h, is secured. This strap is attached to the end of a bar, It', sliding in ways or guides i on the under side of the platform I. On the upper side of this bar It' is a spring-latch, j, so arranged that when the bar passes with it through a loop, k, the latch is depressed. Now, it will be noticed that as the rake is moving toward the elevator the elevator is lying down, without motion, until the rake throws on it the gavel of grain. As the rake recedes the rake-head comes in contact with the spring-latch on the bar h', and draws it along, and, through the strap and sector, lifts the levers S, which, in turn,raise the elevatorrods Q'; The elevator, with its gavel, is carried up the face of the apron T to an open bindingrack,U, behind which an attendant stands. In its passage up it comes in contact with a series of holders, V, of the form shown in Fig. 2, projecting from the transverse frame H.

In passing up, the gavelvis somewhat compressed, and after passing through the'con-- tracted part of the binding-rack and holders the latterclose under it and hold it while being bound. In the meantime the rake-head has'carried the bar `h' along until the springlatch approaches the loop k, passing under which it is depressed, and withdrawn from contact with the rake-head, when the elevator and its attachments fall to a horizontal position of their own gravity, drawing back the strap and bar h'. The rake completes its movement, and in returning with another gavel the rake-head depresses the springlatch in passing over it, and does not engage with it until it again recedes from the elevator.

The shaft of the elevator is provided with a crank-arm, m, whose wrist-pin, as the elevator rises, passing under a cam, W, causes the shaft to partially rotate, and to discharge the gavel into the binding-rack.

X are spools loosely journaled in the frame at the rear ofthe binders platform. On these spools straw rope is wound for binding the gavels with. The rope is led around a pulley, n, through an incased cutting-shears, o, operated by a treadle, o', near which the attendant stands.

Y is the draft-pole, and Z is the drivers seat.

The operation of cutting the grain, raking it in gavels to the elevator, and their delivery to the binding-rack having been already eX- plained, the binding of the gavels is effected in the following manner: The binder, as each gavel is discharged into the binding-rack, draws enough of the hay or straw rope through the jaw of the shear-case to bind it, and cuts it off by depressing the treadle o', which forces the cutter through it.

The free end of the rope is held in place against the pulley by a spring, p. The band is then passed around the gavel held between the rack and holders, and tied, and as the succeeding gavel rises and forces the holders away from the rack, he discharges the bundle at the rear of the machine, when the process Y is repeated, as described.

What I claim as my inventiomand desire to secure by Letters Patent, is-
