IVIOWINGfMACHINE.

SPECIFICATION formingpart of Letters Patent No. 248,329, dated October 18, 1881.

` Application filed July 24, 1879.

To all whom it may concern:

Be it known that I, WM. KEELER, of Towanda, in the county of Bradford and State of Pennsylvania, have invented new and useful Improvements in Mowing-Machines, of

which the following' is a specification.

My invention relates to improvements in front-draft mowing-machines; and the objects of my improvements are to obtain with greater 1o facility the required number of revolutions of the crank-sh aft and the consequent desired increased motions of the cutter, to give to the finger-bar a freer yieldin g motion and greater adaptability to rough surfaces while in operation, and .to improve the arrangement of devices for raising and lowering the linger-bar. I attain these objects by the mechanism illustrated in the accompanying drawings, in whichzo Figure l is a plan view of a mower in a position for operating, with my improvements attached thereto. Fig. 2 is a side elevation of the same, showing the arrangement of gearing around the axle of the transportin g-wh eels and their connection with the remainder of the apparatus as the linger-bar rests upon the ground. Fig. 3 is a side elevation, showing the cog-wheels G D E and their relative positions around the axle A of the transporting.- 3o wheels. Fig. 4 is a sectional view of the interna-l cog-wheel, D, pinion W, and shaft A, taken ou the line ff, Fig. 1. Fig. 5 is a sectional view of arm in of brace L', showing the posit-ion of the main axle A and shafts F and H, as the said axles and shafts extend through said brace to support the driving-wheels and gearing. Fig. 6 is a similar sectional view of arm a, and brace L'. Fig. 7 is au enlarged longitudinal section, taken through the center of 4o crank-shaft F, to show particularly the sleevebox d.

Similar letters refer to similar parts throughout the several views.

The axle A, in combination with the braces L L' and draft-pole P, constitute the frame of the machine. The ends of axle A are connected with the hubs of the driving-wheels B B' in the usual manner.

Attached loosely to axle A is the internal 5o cog-wheel, D,to which power is communicated by the axle by the usual arrangement of ratchets and pawls. Power applied to the internal cog,D,is directly transmitted to another set of gear, O and E, the axes'of which are separate and independent of the main axle A, by the means and in the manner following.

L' is a brace, the lower end of which is secured firmly to the draft-pole P. It tnen extends upward to between the drive-wheel B and the cogD,and isdivided into two branches 6o or arms, m n, which are attached to and form loose bearings for axle A, all as shown in Figs.

1, 5, and 6. One of the arms, n, is shown as bolted to brace L', but, if desired, the whole brace may be cast in one piece. Said arms also form bearing and supports for shafts F and H. v

On the center of shaft H is secured gear wheel E, and on the inner end of.the same shaft is secured pinion W. '7o

Shaft F, with its inner end bearing loosely in arm a of brace L', and having for an opposite bearing box d, secured on arm m, is provided with gear-wheel O, which meshes with Wheel E on shaft H, and has attached to its outer end, beyond box d, crank-wheel O, all as shown in Fig. 7.

To the wrist-pin of the wheel O one end of a pitman-rod, N, is loosely connected, 'the opposite end being attached to bell-cranklever V. 8o

Secured to and having a loose bearingaround sleeve-box d is sidepropellingarm,l ',extending down to finger-bar T and connected with pitman-rod Nbypinp. By this connection the sickle is reciprocated in the usual manner. 8 5

Referring, now, to the operation of these parts, power is communicated through the internal cog, D, to the pinion W, from thence by shaft H to wheels E and O, and by shaftF to crankwheel O and pitman-rod N. Ou the opposite 9o side of the machine the axle A is connected with the draft-pole P by a brace, L, corresponding in form to the brace L', in which the axle A has a loose bearing, but provided with only one arm. 9 5

To the braceL, by means ofabolt, b, a thrustarm, M, is connected, corresponding in form to the arm M' on the opposite side of the machine. The bolt b forms a loose bearing and support for the arm M, and the center of said bolt is on roc the same line with crank-shaft F, which operates the arm M' on the opposite side of the machine. These side arms are thus arranged to operate concentrically with said Wheels; and in connection with the arrangement and opereration previously described the entire gearing is held in rest in any position it may take in revolving about the main axle A. The rear end of each ofthe side arms or bars, M and M', is provided with adouble curveorconvex face, as shown at c, Fig. 1, also shown in Fig. 7, where they would naturally tend to rub against the other parts, and thus a free and yielding motion of the linger-bar is obtained, preventing the parts from binding when one end of the bar is raised in passing over an obstruction, and thus adapting the machine for easy and effective operation over rough surfaces. These arms M and M', which may be made of wood or lnetal, extend or curve outwardly beyond the vertical plane of the wheels B B', and to their lower ends is rigidly attached nger-bar T. The linger-har rests upon the shoes R R, which slide on the ground, or may be further supported by wheels. The lever J and bar I, connected by means of chains G G to the side arms, M and M', form together a silnple device for raising and lowering the finger-bar and other apparatus, and which is connected to draft-pole P and braces L L by means ofloose bearings, substantiallyin the manner and form shown in Figs. 1 and 2.

Draft-pole P is connected with axle A by means of a loose bearing, and as the weight of the gearing above described rests chiefly on the wheel B, such connection should be at such distance from the middle of said axle to compensate for the unequal draft of the wheels, and thus crea-te,'as nearly as possible, a direct central draft, thereby preventing side strain on the horses while operating the machine.

The drivers seat S is mounted on standard Q, which standard is inclined backward, and is secured to the draft-pole by screw-bolts passed through a slot in the standard and secured on the under side of the pole by nuts in such a manner as to make it adjustable forward and backward. The weight of the driver will serve to relieve much of the strain on the draft-po1e.

Having thus described my invention, what I claim, and desire t-o secure by Letters Patent, 1s-

1. The brace L', provided with arms m n, in combination with the main axle, gearing, shafts F and H, and sleeve-box d, for which mentioned features the said brace and its arms form a suit-able support and bearin gs.

2. In a mowing-machine, the side bars, M and M, provided at their rear ends with double curved or convex faces, as shown at c, in combination with. linger-bar T, rigidly attached to the lower ends of said arms, substantially as described.

3. The sleeve-box d, in combination with the arm M', the crank-wheel, the pitman-rod, and the cutter-bar, substantially as described.
