IMPROVEMENT IN REAPING AND MOWING MACHINES.

Specification forming,r part. oi'V Letters Patent No. 13.18l, dated Jnly.,3, 1855;

Reissue No. slhdated 1`)ere1nber 11, 1855.

Figure lis a 'side view ofmy improvedv fnachine; Fig. 2, a. transverse vertical section of the'sam'e, the. plane of Section being through the center; Fig. 3, a plair'ortop viewot' a portion of the iingerbar and cutters; Fig.l4, anfenlarged transverse section of lthe ringer-bar," inger, and critters; and Fignfga plan view of the same, like letters ind icatiug the same parts when in the ditferent figures.:`

The nature ot" my invention consist-s inthe peculiar means employed, which `will be hereinafter described, for elevatingr and depressing the dinger-bar and sickle, and in the peculiar node iu which I construct and apply the fingers for the. purpose of supporting the ends of the stationary knives or cutters nud preventiner thc-critters from becoming clicked.

ioeuable others skilled in the art to fully' understand and construct tn'y invention, I will proceed to describe it.

A represents the frnine of the machine, composed ot' two side pieces-c' a, and snitabe com. liections to support the gearing by which the sickle is driven.

B represents the drivingnvheei, having a gearwheel, C, attached toits inner side. The tlriiingand gear wheels are itung upon an axle, l, which has its bearings in the frame A. :See Fig. 2.) rlhe geurn'vheel C gears into a `union, l), on a shalt, E, which works in suittble beur-ings on the upper part; 'of the fra-nie e. This shaft E also n toothed wheel, F, lpn it, which gears into a pinion, G, hung ipon .rvertienl shafnli. .At the'lower end ot' .he shaft ll there is acrenkqmiley, I, to which me end oi' n pitlnnn orconneeting rod, J, is at- .'iehed.

l( represents the linger-bur attached to one ide oi' the frame A at its lower port. 'To the the frame A.

vAs the machine is dra-wn along the Wheel B,

ower part or edge of szi-id finger-bar fingers c ,rc attached ina substantia manner, the outer t endsof the fingers being provided with knobs or projections d and sockets Within thesame, as shown in Figs. 4 and i5. of the 'nger-,bar K stationaryl cutters c are attached, the outer ends or points of the cutters heilig secured in the sockets within the knobs or projections d, and the fingers formel1-i or bent Y updtard, so as toserve also-as braces or firm audunyielding ysupports to the ends of the" stationary cutters, -as shown in Fins. LL and 5.' L represents the sickle-bar, to which the cu t ters or teeth 'f are attached in the usual manner. These cutters or teetlrf, as well as the cutters e, are` of the usual saw-tooth or triangular form, and 'have cutting-edges at each side. Tnecuttersorteeth 'workdirectl over .Y

and in contact with ythe stationary cutters e. The sickle-bar-works iu guides a", one or more, attach ed to the upper-surface of the tingerbar. .The pitman or connecting-rod J is attached to Vone end ofthe 'sickle-liar Lasshownin Fig. "rf M M are twoverticai bars, the upper ends of which are connected by across-bar, N. These bars M M work loosely in theinnerside piece, a, of the frame A, and have each a small wheel,

O, at their lower ends. To thecenter of thel cross-bar'N there is attached an arn), P, pro ject-ing down ward i-nthe side piece, a., and to the lower end of this arm the outer end of a lever,f Q, is attached by a pin or pivot, g. (See Fig, 2, and dotted lines. in Fig'. l.) 'lheo'ppo site ed ot' the 'levery Q is attached to a shaft, R, on tle frame A,`s'aid shaft having an up'- right arm, S, attached to it. T, Fig. 1, represents the tongue attached to the front end of in consequence ofthe gear- Wheels C F, pinions P G,crank-pulie y '1, and pitmnn or conneot ing rod J, communicates-a reciprocating mot,V

.tion to the sicklebarL, and' its cutters orteeth f work over nodulin 'contact with ythestationery cutters o, andtliergra'ss or grain is cut between them on both sides of the cutters. The finger-` bar und cutters are raised or depressed, so .as

to cut the grain or gruss the required distance from the surt'aeeof the'gronnd. By operating the lever or arnrvS the lever Q, of conrse, will raise or-depres's the-inner side piece, a, and also the`fingebar1 'and' cutters attached to it.

"lhe arm S muy be secured atany desired To the front side` as to cut the grainV or grass thel required distittingpfirmly in the sockets inode in the knobs '0r projections d, and the fingers being conv 'thereto, as fu-llyshown in Figs. al and 5, and

point by a pawl, U, the lower end ot' which hears upon curved or segment guides V V ou the frame A. t

The above invention is extremely simple, and the cutters may be elevated and depressed sol tance from the ground with the greatest fucility.- The stationary cutters having their ends structed so as toforni an unyielding support both sets of cutters e and F having sharp cu*- ting-edges on both their outer edges and ar ranged and operating together, as described, the cutters are prevented from clogging or becoming choked, because the stationary cutters ere prevented from beingdmun downward by the groin or grass which comes in uncut contact therewith, and consequently the edges of `the twosets of` cutters are never separated from this cause, and the grass or straw can never t get between their two rubbing-surfaces, ofthe l cutters become clicked or clogged thereby, jas

lin other machines not'pr'orided with n suicient support to tbc-lower cutters to prevent theirbeng drawn downward or separated from.A the upper cutters by the tractilc action ot' che grain or grass yet fast to the lf'zround, f

Wha-t1 claim as new, and desire to secure by Letters Patent, isfim v 1. Raising and depressing the finger-bnr K, und consequently the cutters f, by ineens et' thezrcrticnl bars M M havin g wheels() (lf si, their lower ends, arm Rattnched to the crossl piece N of the bars lillYLlerer-Q., and shni't lt, with its crm S attached, the :there ifrts lhainggvarrangetl substantially as herein short-fn tml described. D v

2. Supporting the ends of the stationerycnt ters c by means of the sockets, or their equis elents, in the knobs or projections dof the gers c, substantially and for tho purpose ns .forth and described.'
