in connecting;h the lingenhur tothe lnu-ini'ranie by means of an intermediate fronte', the sume being; hinged tothe trent and rear timbersot' the main trunie on a line with the. crunk-shaft, as hereinafter described; second, in the inode herein described Afor raising land loweringthe mitin ti-:nne so as to adopt the machinefor mowing und reaping; third, the plun and construction ot' my finger-bur und guards und the munner ot' securing,` the guards to the tingen. 'nur and ot" operating the cutters therein present thetollowingdistinguishingfeatures: first, the linger-intr is made in u n ogen forni; second, the buse oi' the guard is marde to conform to the ogen torni et' the. tinger-bur, so as to rest npon the upper side thereof and support the euttetwbur, u mortise heinev mudo through the l'ront curve ot' the linger-bar, through which thegnnrd posses, the under part of the slot being on a level with the edge of the fingerbar; third, in locatingl the cutter-bur in rear ot the t'iont edge und over the. tngetgbur, so its to niow the cuttinged-ge of the cutters-to t-rnss the edge ot' the. lingerEbar and clip the grass or j rnin as nein' as possible to the tin- ;er-baii:

'lheinger bur, by meansotts connection to the inside sl oe, is ilso connected to this frame, sfr that when connected to the main frz ine the t'hole will hinge or turn on the holtsp' an'dp", and u perfect adaptability of the n'ger-hanto uneven ground is tiiere'hyf`etiectetl. C, shaft of pinion and bevel-wheel; C', shaft ol sinull bevel andlspur wheel; crank-shaft.; D; shaft which supports segment-gear H and H' LA J J, standards whichl support the shat't D. These standztrdsjare bolted firmly to the ina-in ironie. Reest-iron frame, which turns on the journal-boxes of shaft G, the journal-boxes heing extended andtitted for this purpose. The driving-wheel A'and hearing-Wheel A' are connected to this vfronte by separate axles. The geared segments I and I'r are also supported `on thisi'ruine. These segments mesh in with l segments H and Ll', und by means thereof the main freine can be.l rztised and lowered us desii-cd. The lever L isconnected to the shaft l), and is operated by the driver while on his seat, und gives hiinl power-to work the seg;- nient-gearing, and thereby to raise und lower the main trame zt-'she pleases.

P 1s a bar of iron, bent in c circular forniI and bolted to the frame D', and'is for the purpose of holding the lever L' in any required position; 0, Fig. 3, casting, which forms n palrtofthc hinged frame B. It is firmly bolted to the Wood part B', from which it projects. A similar casting' (and connected in u similar manner) is represented ut OQFi .l. Bymeans of. these castings a connection c n be formed .with the main fratrie (in front and rear) at about midway between the driving and bearing wheels. This arrangement prevents a side draft, and relieves the drag ot' the iinger-bur'upon the ground. S, inside shoe; R2,

B2 shows'the end ot' the finger-bnr, and they manner ot' its connection to and support in the shoe. M2 is a'grooved cap-piece o1" the same width of the shoe. Bolts pass through this cup-piece and iinger-bar and lower -part o'tlthe shoe, and the finger-bar is thereby compressed A groove, h1, made in this works. 1t?, end ot' rod, which passes on the under side ot'the iingerbnr and tonnects with the outside shoe.

Fig. 5 is a plan ota portion ot" the linger-bar B2, cutter-bnr C B, cutters K', and guards (i2 as arranged together. Thisarrangenicnt brings the cutter-bar in rear ofthe front edge ol" the iinger-bar, and thereby prevents all possibil- :ty of clogging between the back ot' the cutter-bar and -i'nger-bur. It also enables me to use a shorter guard, and const quently u guard olless metal and less weight. Vltalso eiinbles me to sever the stalks ofgrass or grain close to the iingenbar, and renders the gruss less liable to lodge or benk thereon. t The ogee forni of the finger-bar enables ine to make it thinner, and consequently a less amount ot' metal and less Weight. It Ina-y be giventhe proper forml at the rolling-mills, or itmay be forged. This form' f bar also gives greater strength and stiffness, with aless amount of metal than any form heretofore adopted within my knowledge.

Fig. ti is a plan ot the tinger-bnr guards and outside shoe, bottom upward. The rod R* passes along on the bottoni ot the iinger-bar in the curve and connects with the segment".

Fig. 7 is n. lsection, of the tingerbar .and guard, and shows how the guard lits onto the linger-ban. 'lille guard passes througlrthe mortise c, Fig. S, and restff upon the upper side ol' the linger-bm', sind is held tirmly thereon by the rivet n, which passes through both.

Fig. is c i'ront elevation ot' the finger-bin', for the purpose ot' showing more distinctly the inortise c, through which the guard passes. he guard just fills this niortise, and is thereby held firmly in its place, and is prevented i'rotn working sidewise or becoming loose.

The vguard ma); be made oi` malleable iron or forged.

Connecting the ringer-bar to the main frame by incunsol' the intermediate frame, 0, und 0', the same being hinged to the tront and rear erosstiinb'ers ot' the main i'ranie on a line, or nearly so, with the cinnk-sliat't,ior the 'purpose of relieving thc dragot' the linger-bar upon the ground und allowing it to conform to uneven surfaces without varying the throw ot' thc cutters through the guards, substantially as herein set forth.

L. The arrangenicnnot' the mechanisin,as herein described, for the purpose ot' raising and-lowering the mitin trame ot' the inzichine.

5. ill-tilting the linger-bnr in the'fogee forni.,
