Torall whom it may concern.'

l Be it known that LjPELLsMANNY, of Waddams Grove, iti-fthe county of lStephenson and State ofIliinois, have invented certain A new and"nset'ul I mproveincntsin' Keeping-Machines, of which thevf'oilowingis a full, clear,

and exact description, referencebeing had toy the accompanyingdrawings,,tormjng part ot'` this specification, in whic -s f Fignrel is aperspecytive vientof the machine-1 complete, withthe 'ex/cepltioriof `thcendless band for discharging `the cnt grain. Fig. 2 is aV verticalA section of aportionot the machine,

y showing,` 'more yparticularly the revolving ,cut-.j

ters and theatrang'ement for raising and lowjl erlng the cutter-frame; and Figs'. 3, 4,-and 5 are plans of various: portions of the machine, the firstYshowing'theirrangementot'the pole, v

the second tbat'of the stationary knives, and.

-the iast the arrangement ot the tightening- -roiler of the endless band for discharging the cut grain'.

My invention consists,- `first, inconibining revolving spiral cutters with a. series of staf ytionary-knives,`the two being so arranged with respect to each other as to act on the standing grain likethecutting-edges of'a common shears; second, in raising or loweringl the cutter-frame in snchnianner that the cutters` shall always act upon 'the grain at the angle 'best suited to the dista-nce from the-gronml .nt which. `the straw ist-ut, while the band which-,eitjes mo- .tion to the revolving cutters shall heal-ways v kept equally stretched, irrespective'ot' the position ot' the cutterft'rame; third, iu themcthod ot' alteringl the direction ot' the progressive mo Afion ot' the machine npoithes'uri'acc vot' the ground. l

The general arrangement ot' my renper is as follows:` Fingers project from the front ol' the machine, which, by the progressive motion ot'. tli'e carriage, enter the standing grain and direct. it against stationary knives placcd-at-thcir bases and runningdiagonally i'rom finger to4 ling-er. A series ot' spiral c'uttcrs,'driven b v a band l'ronrthe wheels oi' the carriage, revolve immediately above the stationary knives, and, acting' with Ithem, shear oi'tl` the. grain. 'lhecut grain t'alls'upon au endless .hand running on rollers, also driven by the' progressive motion ot' the machine, and by this band it is discharged into .a wagon moving beside the reaper. lhe'franie' which car-` ries the moving and stationary cutters and `the discharging-band can be raised or lowered at. pleasure. The pole to which the horses are attached projects from the hinder part of the carriage, its projecting extremity being supported by a wheel. 'It is lattached to the car- 'friage by a pivot on which it turns, and. has

two ropes attached-to its extremity within tho carriage. which, proceeding in'opposite drec tions to the sides'voi'I the carriage, pass round sheavestherennto -at.tac`hed,and are returned rectionsnpon thebarrel ot'a ivindlass; 4By applyingthe hands to the spokes ofthe windlass the pole is moved in either direction `from the central liuc passing through ythe pivotin the same manner as the tiller of-a vessel is worked. ln thel drawings, A isiheiraming ot' the carriage, B being the axle-tree, onwhich thc wheels G revolve. Attire front end ofthe machine is the cutter-frame I). From the lower part of this frame lingers a are projected forward, to whose bases stationaryvkniv'es b are attachcd,'wljiich ektcnd diagonali-y across thc spacesbetwen the lingers.

Directly above the rstationary knives is the shaft c ofthe skeleton d1'nni,to which the mov .i ing cutters are attached. This drumis t'ormed ol' two heads, E E', mounted on the opposite extremities ofthe same shai't, iQ-and connected i by 'longitudinal picccsF, extending spirally from onehead, E, to the other, E'. These pieces are connected with each other .by suitable braces, d, and to them the movin g spiralcntters c a reA attached. These cutters are made otthin .sheet metal, and are so larrangged that in pass ing,"I over the cdgcs of the stationary knives l an angle shall be. t'ormed between the edges ot' the two, the moving? cutters first meeting the stationary knives at these parts ol' their edges, which byA their diagonal position .project farbackward toward the inneranglo formed by its inner extremity is attached, thus'jshearing the grain in the same manner as the edges ot' an ordinary shears cut. lt isimportant that the stationary cutting-edge should be coinposed ot' a series of knives instead of one uubroken'cdge, first, because the cutter-frame can be shorter, (in the direction of the motion ot'A the carriage and, second, when the I'inives become dull aless amonnt ofgrain accumulates toward each other andfwoundin opposite di.

thest into' the slanding .grniinand advancing the stationary kniieaud `the. tingerto whichstrained.

at' the inner angles formed by them with thel gngers, and the power exerted tocut such ac cumulation of grain will be less than it' the stationary cutter was one unbroken edge, iu

the ratio of the number of divisions in the series. The cut grain-iscarried backwardby .the'revolvingcutter' and discharged upon an endlessband vrunning on rollers H H trans versely across the machineand projecting beyond its side at I. The outer roller of this ba'nd is supported byan adjustable frame, J, hinged at its inner extremity to the cutterframe D. The projectingextremity'is connectedwith the upper part of the cutter-frame and supported by straps'which may be shorten'ed or lengthened to elevate-or depressA the `projecting extremity ot` the roller-frame J.

The'roller H', at the projecting extremityof the frame J, is not fixed', but is continually forced outward by springs g, acting. upon the sliding supports It of its axis, so as to keep the discharging band constantly tight. The revolving cutter-drum is driven from 'one of the carriage wheels by a belt, L, which* passes over a belt-pulley, K, secured to-the spokes of the carriage-wheel, and overa second pulley, K', on the 'shaft ofthe cutter-drinn.

The cutter-frame D is suspended from Aone extremity of the lever M by the links N connecting the two. To the opposite end ot' this lever M a rope, i, is attached, which, proceeding downward,pa sses under a sheave, j, at-iv tached to the fra'ine of the carriage, and thencev returning upwardvand passing overa second sheave in the extremity of the lever, (by which its direction is. changed,) and under a third vsheave =on the carriage, is brought upward and around upon the barrel of a windlass, 0, by turning which 'the cutter-frame is raised or lowered.

`In order to regulate the angle at which the stationary cutters meet the grain in the several positions of the cutter-frame, and at the same time tov keep the driving-belt L always equally strained,-Ihaveinveuted the following arrangei' ment: Circular ways I, concentric with the axis of the wheels, are attached to the, frame" of the carriage, and corresponding oues,"P, to

.the cutter-frame. D, whose' centers coincide with that of -theshait of the cutter-drum'E. These latter slide. upon the former, and as the circular ways are concentricA with the pulleywheels K K thedistance between-the axes of the latter' will -not .be altered by raising or delpressing the cutterframe,and the-dri vingbelt` L', surrounding the two, wil l always beequally In order Vthat the stationary knives b may always meet the grain at a proper' an'- `ting the grain.

The pole 1t, to which the team is attached,

an upward inclination, thus being .always placed at themost advantageous angle for cutprojects from Athe hinder part ot'/ the carriage, and has its prnjectingextreinity, to which the whiftletree is attached, supported by a wheel,

l, above which is the seat m of the driver.v In

' order to direct the reaper, I attach the pole R tothe carriage bya pivc't, u, o'n which it can be moved horizontally in either direction from the -centralline of the machine. The inner extremity, r, ofthe pole projects within the pivot n and has two ropes, o o', attached to it; which, proceeding horizontally in-oppositedirections, pass under sheaves p p',a'ttached to the outer i'raming'of the carriage, and thence, returning inward and upward,.are wound in opposite directions-upon the'drutn s ot a windlass, 0l. The hands of .the director are lapplied'tov the spokes o't the windlass-wheel O", and-, acting through the ropes o o', haul the inner extreniity of the pole to either side in the 'same' |nan` lner as the tiller ot' a vessel is turned for the purpose of steering.
