`s'peeilcation forming part of lettrrs Iatent No. l.1,7lll, d-itrd September lil, leal/l; ltei sne No. 20|. dated lie it known that l, auxin; WnrrELEv, ot' Springlield, in the county ot' Clarke and State ot Ohio, have invented a new and useful Improvement. in (train and (lrass l'larvesters; and Ido hercblv declaiwA that the following' is a full, clear, and exact desrrlption of the same., reference being had to the accompanyingdrawings, making part of this specitication.

This improvement embraces an automatic raker or deliverer ot' the cut grain received on the platform of the reaper, aml several important improvements of the reapei' itself, such as the improvement in guiding' the grain (when being' reeled down onto the platform) into the end ot' the reel, so as to incline the grain sufficiently into the reel for the ref" to take hold of that part ofthe grain which L mes in front of the divider and reel it down t ito the platform; also, in placing' the fingers 'unprovided with slots) on alternate sides y the cutter blades and bar, the edges of which are also alternating'.

In the accompanyingl drawings, of which Figure I isa perspective view with the extra. platform detached, A is the mas er-wheel; B, the tongue, (the extended end emoved;) C, the drivers seat, and D his foot est; E E, an angular framel rising from the tt gue and main frame 1T' I". G G' is an angular frame; and between these two is placed the linger-bar Il and platform for receiving the grain. I is the nose or grain-divider. Behind Il will be noticed a parallel brace, K, whose object or use will be hereinafter explained. L 'n' are rakee'uides, in the inside ot' which the ends ofthe rake are guided; and it will be olrerved that the outward one, L', is not. confined to (r at its lower end, said lower end beineY part of the nose, while the other one is secured 'to the side ot' the platform M. This arrange'I ut of L is necessar.)Y to permit the grain to s between the brace G aud guide.

N is the reel-shaft, a a a, the t. Aree sets of arms thereof, and b b the remainim pa-ir, coustructed so as to admitthe rake to swing between them at their' insertion in t` shaft N. c e c are bla-des on the arms a. a u.. (t unites the fourth set and forms a suspending-point for the rake. r/g/ are loose-fitting straps hing'- ing' the blade d to the bars c r, and the bars c April l, l

e are framed into the rake O. These several arms are suitably braced. ,/'is a lever-latch passing` through shaft N, being' pivoted at h, and retained in its locked condition by the loop I when theI knec-lever l is moved toward the right. by the driver. h1 is another self-droppine' latch, h v means whereof the rakefhead t) is retained between it and f when locked. It is a pulley receiving,r motion by a band on a pul` le)Y on the driving-pinion shaft. The reel admits of adjustment of height,- to suit the grain.

I represents one of the two upper guides for the rake O, leaving a space between it and S- one otf the ways on the platform. l q are guides between which the ends of the reel rods or blades pass when the reel revolves, and serve to incline the grain into the end of the reel,so as to be caught by the blades and carried onto the platt'o1'i1i--e., the grain in front of the divider.

T is a metal rod connecting the extended rear end of M with the upper end of Ii', and V a second rod continuing the Connection to the main frame F. It is by this arrangement that an)1 weight received on the nose I is transferred to M, and thence transferred to the end ofthe tongue B.

The cutting part is designated by tlgures or numbers. 3 is the slide-bar on which the outters are secured; 4 et 4, a series ot' plain-faced lingers-that is, without guard or under piece or slot. 5 5 5 are alternate lingers placed with their faces upward, being' the reverse of t 4 4. Between these sets the eutterblades work, and to meet the requirement of alternate fingers the edges ofthe cutters also alternatet hat is, every tooth has its edges alternate, the one shearing against the upper finger during one stroke of the crank and the other shearing' against the under tugor adjacent to it during the other stroke of the crank. Said teeth are made rights and let'ts, so as to place them alterv nately ou the cutter-bar, and the two adjacent edges which cut against any one ofthe lingers will be beveled the same wa-Lv, so as to cut with a close shear-edge against both sides of every finger, and it is by this arrangement [obviate all difticulty ot' choking, and by the cutters being' sprung in opposite directions it will be seen that. the spring' of the one will balance the spring of the other and always leave the bar loose in the lingers, thus avoiding all bindin;r in the lingers when the cutters dull, and preserving,T the line ol' cut.

'lhe operation ot' the rake is as follows: llein;r hung,r on one of the rolls or blades, it is liioughtintoplay, (when not locked by the bolt.) and on the revolution ot' the reel it drops by the weight. ot' the. rake-head l), the ends ol' which falling' iii the guidi-s or waysl li l., and enters the ,g'rooved guides near the platl'orin, where it takes the buttot' the gialli pil-rionsly laid bythe reel and travels across the platl'orin en the extended ends nl' the ways. dnlivv ering the ,e'raiii by pushingr it bet'oi'e the rakehead1 either over the rear ol' the platl'orni nr onto a seeoiid plall'oi'ni with aside delivery. 'lfhe rake-head, on its leaving' the grain. lo .i receding movement rising, the. reel is' ready for another stroke of' the rake, as in the tirs-t. 'l`he oliieet ot' the extended upper portion ol' ille llides ll 'li' is to l'llziili llie ruhe-limiti therein during' its passage over the r'ei'l'shal't. the [ront portion ot' said guides l. li serving' to guide the rake thence down to the platl'orin, the extended ends` S S Serving' to make itspassage over the. platform more easy. The. inanner oflocking the rake-head iii light grain, so as to allow a number ot' revolutions ol' the reel to intervene between each action ot' the rake and accumulate a bundle on the. platt'orin, is by the knee ot' the driver operatingthe leverlatch on the one side7 while the drop-latch eurestheoppositesideot'tlierakehead. When the lock is notJ used the rake t'reely operates on each revolution nl' the. shalt N, the guides i, il and the upper one, which is not marked in the drawings, all extending' into the end ot the circuit ot' the reel rods` or blades when the reel is working at its lowest point. the grain is forced into the end ol' the reel as the machine is drawn forward. the slanting t'ront ends of Said guides pressing the grain gradually into it, and each rcel-roll is conipelled to carry to the platt'nrni the grain which comes in between it and the rod preceding it1 and thus prevent the grain accuinulatin,r on

the divider as it is being cut, and also prevent. i the saine masning down the grain in front ol the divider' and running over it., as it will when Q the grain is allowed to accumulate on the di vider, and as the reel is raised to the higher I points, the upper guides still performing the W' 'le are two ofthe sickle-teeth, j
