do hereby declare that the following is a full,

clear, and exact description thereof', reference being had to the accomp gdrewinlg, picking e part of this speoicetion, in w c Figure l is a plan View of my improved ma chine. Fig. 2 is a side elevation of the seme with one traction-wheel removed; Fig. 3 is a..

side elevation of thc crank-shaft and-driving- Ofeor. Fig. 4 is a like view of the lever used lorrelevating end depressing the cutting devices. Fig. 5 is a horizontal central section of the crank and pitman or connection-box; und Figs. 6 ond 7v are aplan view and side elevation, respectively, of the pitmanand cutter. har at their point of attachment.

Letters of like name and kind refer to like ports in each of the iigures.

My invenon relates to e class of machinery used for cutting glues and standing grain; und it consists in the employment of. e male and female spur-gear wheel, positively driven by the seme gear, and caused to mesh with the crank f shaft pinion from.l opposite sides, substaniially as and for the purpose hereinafter set forth.

It also consists in the means employed' for ecuring vertical adjustment of the forward end of the frame, and of the cutting device attached thereto, substentielly as end for thc purpose hereinafter specified.

.In the annexed drawing, A represents -the cally downwardhis provided upon its lower which flu'nishes. a bearing end with a box, for the rear end otl the crank-shaft F, the front end of kwhich is supported within and by a similar box, g, forming part of a second brace, G, extending downward from the front portion of the said frame.

` .rammed loosely upon nie lme Bis eben. shepedbevel-gear, H, made concave inside of the line of teeth, and provided, upon the outer end of its hub h, with sltable radial grooves or notches, for the reception of corres'ondmg elevations'upon the contiguous face el asliding clutch, I, of usual construction, by'meens ofy which said axle end gear are locked together, so as torevolve et one and the same time.

A beveledI pinion, K, is secured upon one .end of e short shaft that restswithin a box d, 'forming a part of the brace 1,),and m with and receives motion from' the gear H which motion is communicated through se' shaft-to e spur-gems(i Lthottached to the rear end of -the letter an ugh said gear L to the crunk-shaft F, by means ofthe pinion M, at-

emes to' and crankshaft, :ma mening with said vspur-gear.

A second bevel-pinion, N, corresponding in size with the pinion K, is attached to one .end of e. similar shaft, which rests within o box,o, formed within the outer end of a brace0, that is so attached to the frame A in the rear ofthe axle B as tocuuse said pinionN to engage with the geur-wheel H.

, A-female gear-wheel, P, corresponding in interior size 'und number of teeth with the exterior of the spur-gear L is attached to or upon the front end of the shaft containing the pinion N, und meshes with the lower side of the ipinion M upon the crank-shaft, to accomplis which result the rear shaft containing said female gear is dropped downward below the corresponding front shaft a distance equal to the diameter of seid pinion M.

As thus arranged, it will be seen that, the motion of the axle is commimioated to the crank-shaft pinion M through two trains of gerin-viz., the bevel-geur wheel H pinion K, an spur-gear L--andv through the said bevel-gear H, pinion N, and female gear P, and that as saidtrains operate upon seid crankshaft pinion M from opposite sides the strain -und pressure of each thereon will zbe neutralfemale geur Pis to enable the crank-shaft 'pinn frame A is a. supplementary frame,

- depressed.

ion b e driven from opposite sides, while th-shafts ofthe drivinsrgeer er@ upon the. same side -o'fseid pinion, and capable of being actuated bythe sume gear, so as theleby to reduce the number of gearing required to coml muncete the motion of thelsxlc to the cutterbalgtxend also render. 4seid gearing more comlm Y l Hingedfto'or upon the lower side of the i12-vins said ame, if

In order that said cutting apparatus maybe edjustedyerticallyto any desredpositiomthe followipIgdescrbed means are employed: A ly'er, ,proyi'ded etl its lower. end with a short W projecting outward. eta. right angle toV e e of seid lever is pivoted et seid end loosely upon the axle between the frame und the traction-wheel, so as to have thereon n. motion in a. line with the A chain-,'10, is secured to the-end of the erm WI, tothejiiamne Q immedietely beneath, so' thatiwhen the lever V' is raised toward a. perpendicular lposition or dropped forward, saidirame and the inner end of the cutting apparatus willbe correspondingly elevuted or 'To raise the outer end'of the inger-bur a connection, -X, is pivotedet one end to the ie ver Vfrshortv distance' fa'bovethe axle B, und

fromthence extending forward hos its opposite' en d pivoted to the upper 'end of the rod Y, whch rod extends downward to the .beuring y), secured to or upon the erm R laterally outward through seid bearing, and is then cerriedto. the side of said ammiand terminotes og short downward bend. j A short arm, u, secured to the rear edge of the finger-bemand extending inwardbeyond the hinge and beneath the end of the crankroclgY, completes portion of the device, the pemtion of which is as follows: Upon raising the lever V the upper end of the rod Yiis drawn -to the rear, so es 'to cause its lower endto press downward upon the arm u end raise the outer end of the finger-bar. VUpon 'reversing the movement of the lever V the finger-ber is lowered to its former position. 4 I

The lever Vis locked'v in position by means of a toothed quadrant, @attached et one end to the'frene A7 and passing .through u suits.-

ble guidel o,sec1ned upon the side oi'gseid` lever, en eugagingwith a. detent-rod, operated by means of 'a hand-lever, z', iv oted upon or near the upper end ofszu -lever Y. f

The draft-pole A' is not attached directly to the moin frame, but to u sectional freine,

B', which is hinged et itsrear ends to or upon en., es with a detent, D', working within a.

barre -guide d', attached to said'pole, so esto loekvsai a paie and the mein neme in any ae- VAsired relative position. Y

In order that the detent D' may be withdrawn from the segment C a. ioot-lever,-E, hawing'the formshown in pivotedto or upon. said pole, and provi ed with an arm, i, which extends downward into a," slot within said. detent, so that when said foot-Ieverispressed downward suiddetent is carried forward, releasing it oln seid ment.

As thus arranged, the 'cperetor may change .the relative positions of the mein frame and pole, so -nsto' raise or depress the cutting apparatus, by simply pressing downward with his foot upon the leverE und then moving the louer v forwiud or bac 'ord without withdrawing the detent e from engagement with the segment Z. Y

-The box E' loi the connection or pitmnn G' is provided with e cap, f that screws over the outer end, and 'compfetely ineloscs the outer end of the crunk-pin f, so as to not 'only exclude all dust and the box the oil use for lubrication. Upon the bearing at .the opposite-end ofthe pinnen G', I shrink e collar, g', having a, dif mneter of about two inches, and formed of .steel composition, or any desired metaal, by

wliic i means a. large increase in bea. -sursimilar bearings of ordinary construcwithout unnecessary mzdtiplica'tion of ports,

perfectly equalizes the strain uponA the crankshaft, so as to cause the letter to revolve es freely within its bearings-as though entirety 'disconnected from all mechanism second the means employed' for giving vertical ndlustment to the 'ibrwnrd end of the mein frame, and-of the cutting devices attached thereto, are easil f constructed-and adjusted, efficient, und y operated,l end, in connection with the means used for securing the vertical adjustment of the outer end of seid cutting 'devices, give the operator. complete control of the machine upon or over uneven ground.

`Having thus fully set forth the nutureand' merits of my invention, what I claim-nene 1. D1' n reaping or mowing machine, u.- mele und a. female spur-geerwhcel, positively driven in opposite directions by the'same geur-wheel,

and yto mesh with undimpert motion to but also'to retain face, und, consequently, durability, is secure@ a crank-shaft pinion upon opposite sides of the same, substantially as and for the purpose specified.

2. 1n combination with the main fra-me A, the hinged frame B' the pole A', the segment G', and the detent b', the f0ot-1ever Ef, the lever V, and the toothed segment Z, for the purpose of securing vertical adjustment to the forward end of said mein frame, sulistantinlly as shown and specified.
