T0 @ZZ whom, t 71mg/ concern: 2

Be it known that T, J Atras H. JoNEs, of Scotland, county of Scotland, and State of Missouri, have invented anew and useful Improvement in Mowing-Machines; and I do herebydeclare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use it, reference being had to the accompanying drawings, forming apart thereof.

My invention relates to improvements in mowing-machines, and it consists in the construction, combination, and arrangement of the several parts, as will be hereinafter defv scribed and claimed. 1 In the drawings, Figure l is a perspective view of my machine, and Figs. 2 and 3 are respectively top and bottom plans. Figa is a front elevation of the machine with sicklebars elevated. Fig. 5 is a side elevation of the same with a wheel removed. f

The main frame of the machine has its side bars, A A, pivoted on the axle B,and its front bar, A', is provided with a suitable opening, A2, through which the tongue A3 is passed- The side bars,A A,are j oined at theirrear ends by a cross-bar, A4, as shown. The axle B has bearings in the side bars, A A, and also in beams C @,which are bolted or otherwise made fast to the outer sides of the bars A, and extend above and below the same. The portion of each beam above the bar A is formed or provided on its inner face with a series of rack or ratchet teeth, c, for the purpose presently described.

In addition to the main frame I employ a supplemental frame composed of side bars, D D, and end bars, D D2, arranged as shown most clearly in Fig. 3. This supplemental frame is pivotally secured near its rear end to the lower portion of the beam C, and ex tends forward under the axle B. I journal a shaft, D3, in the bars D, immediately below the axle B,aud this shaft forms the pivot upon which the supplemental frame turns. On this shaft I secure the bevel gear-wheel D4 and the pinion D5, the latter meshing'with the gear B on the axle B, as shown.

In operation the axle B is revolved by the wheels B2, spindled on its opposite ends, the4 said wheels being provided with pawls I), ar-

ranged to engage the ratchet-wheels b', keyed on the axle, and thus the axle B and wheels B and D5 D* will rotate together, as will be readily understood. The pawls b are pivoted to the wheels. A crank-shaft, d, is journaled at its forward end in the bar D,thrcugh which it passes, and near its rear end in the lug d, projected from one of the bars D, and it is provided on its rear end with a bevel-pinion, di, meshed with wheel D4, as shown, whereby the crankshaft d is revolved. `A yoke-shaped hanger, E, is pivoted at its upper middle or crown portion on the shaft d, immediately in front ofthe bar D', and -its opposite ends extend down close to the ground and have pivoted to them the inner ends of the knife-supporting iinger-bars E.- These iinger-bars are provided on their under sides, at each end, with a supporting runner or shoe, e, and are constructed with guides or keepers e'ei,whicl1 serve as ways for the knife-bars F, which slide therein in their reciprocating action. These knife-bars F are secured in the keepers e e2, and are connected together by the link F', pivotally secured at its opposite ends to the inner or adjacent ends of the knife-bars. This link is provided with a. central slot, f, which is elongated-vertically, as sliowmand in which works the crank or eccentrically disposed pin cl3, secured on the end of shaft d, so that as the said shaft is revolved the crank d, working in the slot f, will give the link F, and consequently the knife-bars F, a simultane- .ous reciprocating motion. The seat G is mounted on the beam G, which is supported midway its ends on the springs g, extended from the side bars, A. These springs form practically a pivot-support for the beam, the forward end of which is connected by chains or cords g with the forward end of the supplemental frame, so that the weight of the driver serves as a counterpoise of the cutting apparatus connected to said supplemental frame. For the purpose of raising the cutters, either one at will, I employ the levers H H and I I. The levers BI H are pivoted at one end to the inner side of the bars A, and extend therefrom at right angles over the opposite bar A, and are connected at their outer or ,free ends with the ends of the yoke E by chains h'. rIhe levers I are pivoted at their forward ends to the bars A, and extend rear- IOS ward, each under one oi' tl1elevers,and at their I with a crank-pin working in said slot,and necrear ends are to lie held by the ratchet-bars c at any suitable elevation. The particular arrangement' and operation of these levers will be fully understood i'roin Fig. 1.

By the before-described mechanism, it vfill be seen,tlie machine will eut a swat-li on opposite sides of the machine, and one or both oi" the cutter-bars may lie raised ior any desired purpose.

Any ofthe ordinary vvelllknown provisions for throwing,` the machine into and out ol" gear inay be employed. Many orins are vvellreals, and I do not deein it necessary to illustrate such.

Vhat I claiin as iny invention, and desire to secure by Letters Patent, is-

l. In a inowing-niachine, the combination, substantially as set i'ortli, olI the l iiilel ars,tlie suitiporting` iinger-bars, and a yoke or support connected midway its ends to the traine by a pivot-joint, and pivotally secured at its opposite ends to the finger-bars, and the i'ieeessary operating` mechanism, as set l'ortli.

2. In a mowing-machine, the combination, with the pivot'ed yoke, ofthe linger-bars pivoted to the opposite ends of said yoke and provided ivith guides or keepers, the knife-oars placed in and operating` through said keepers,

the link connecting said knife-bars and provided With a vertical slot, a shaftprovided essary ouerating mechanism, as set forth.

3. In a moving-machine, the combination, ivitli the slial't d, geared with the operating` mechanism and provided with a crank, di, ol" the yoke pivoted on the said shaftand having the finger-liars secured to its opposite ends,t`ne knife-bars, the link connecting` the saine and provided with a vertical slot engaged by said crank di", and nieans for elevating,1 the yoke at Will, substantially as set i'ortli.

4'. In ay mowing-machine, the combination its opposite ends, .the levers H II I I, chains or ropes h, and tlieneeessary training` and operating; ineelianisin, as sot forth.

5. The combination, in a mowing-machine, ofthe axle B, the ratchet-wheels D', the gearivlieel I, scoured tl'iereon,the pawls arranged to engage the ratchet-wheels, the Shaft DilpreV vided with rear-wheel il and pinion B, the Shall'. d. having pinion d`l and crank d", the yoke pivoted on the shaftd, the cutting` apparatus secured to the yoke, the link F', having slotf, and the necessary l'i';iniiiig,as set forth.

In testiinony that I ('laiin the foregoing I append my signature.
