SPECIFICATION forming part of Letters Patent No. 395,349, dated January 1, 1889.

Application tiled January 29, 1887. Serial No. 225,898. (No model.)

To @ZZ whom it may concern;

Be it known that we, .Tol-IN HILL REDFlnLD, SAMUEL HALL REDFIELD, and ABRAHAM ED- WARD HANSBRO, citizens of the United States, residing at Glendale, in the county of Douglas and State of Oregon, have invented certain new and useful Improvements in Mowers; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures ot' reference marked thereon,which form a part of this specication.

The invention will first be described in connection with the drawings, and then pointed out in thc claims.

Figure l is a plan view showing the parts of the mower connected together. Fig. 2 is a front view ot' the same. Fig. 3 is a detail view ot' the axle. Fig. -fl is a trout v'ewof the cam-wheel, parl'l)Y in section. Fig s a crosssection ot' the axle with connecting parts. Fig. G a detached view of the outer shoe. Fig. 7 illustrates in side view the shaft with oscillating arms,which is actuated by the camwheel.

In the drawings, A (lesigna'les the draftpole, which is secured to the angle-plate B by screws and between the flanges Z1, the said plate being held to the axle by clips ,which embrace the axle-'tube D. The curved seatbar E is held between llie rear end ol' the pole and ol' the plate i3, while the seat is supported on :its more elevated and forwardlycurved end. The axle F passes entirely through the tubular bearings lf), and is threaded at each end to receive the axle-nuts G. At or near the ends ot' tube D ratchetwheels l are placed on the axle and made fast thereto, the grouinl-wheels K being placed next and the nuts G being screwed on the extremities.

The hub k of each ground-wheel is provided with a tubular flange, lr, on each side, and the ratchet-wheel l has an inward tubular extension, H, and, as shown in Fig. 3, the parts are so constructed that the outer ange of the hub extends under a rim ot' the axlenut, and the inward flange, extends under the ratchet-wheel, the extension H of which extends under the end of tube D, the axle being thus e'ltectually inclosed for the exclusion of dirt. The wheels K are loose on the axle, and the hubs la are provided with the diametrically-opposite spring-pawls k2, which engage with the fast ratchet-wheels I, so that when the wheels move forward the axle revolves with them; but when they move back- 6o ward the axle is not rotated with them and the cutting mechanism ceases to operate.

Loose on the axle is arranged the large spur-wheelV L, which carries one part, Z, of a clutch, the other part, in, being movable, feathered to the axle, and (i'onnected with a forked lever, M, by means ot the pins m', which stand from the arms of the fork ot' said lever into the circumferential groove m2 oi' the part or section my ot the clutch. This le- 7o ver M is pivoted to the piece m, fixed to the frame, and carries at its rear end the pin m4.

N is a lever pivoted to the frame at n and placed at right angles to the lever M, and having the inclined slot nin its outer end, which slot engages the pin m4. The pin m4 on the end of lever M is connected with the fulcrum screw or pin n of the lever N by the spring O, the office of the spring being to keep the clutch locked. This construction of 8o lever N with curved slot In. for engagement with pin Int on leverM serves to facilitate the proper movement ot' M, and also assists the retaining-spring O in holding the last-mentioned lever to keep the clutch locked. The

power end' ol the lever N is connected by the rod o with pivoted handle l), which moves in a slot, g, of the lixed plate Q, which has a shoulder, g', behind which the handle P held to keep the parts l m of the clutch apart. 9o The spur-wheel L meshes with apinion, L', which is tasten the shaft R, which carries the cam-wheel S. The latter is made in two parts, S', each with a tube, s, provided with the slots s,while the shaft R hascorresponding n otches, 9 5 r. rlhe keys r2 are beveled on their outer edges, so that they narrow downward, the slots o and notches conforming to them. They are passed downward in the slots and notches, and may be ixed at any desired adroo justment by means ot set-screws s2, and by these means the sections S may be adjusted on shaft R toward or from each other for the purpose of taking' up wear or to make the wheel work with as little friction as possible, the parts being' so constructed and ar rano'ed that the inward adustn'lent of the two sections is effected by pressing the keys r2 downward. (See Fig'. 4f.) The shaft R may be adjusted longitudinally by means ol? the screw-bolts The cam-faces of the sections i are in equal altern ating' convexities an d concavities, in order to uniformly vibrate the shaft T, which has its bearin 'in iframe V, surrounding the cam-wheel and gearing', and is proA 'vided with the forward arms, '/r, and the rear arms, t. (See Fig. 7 The arms if carry friction-rollers t2 on studs or pins Ai'or engagement with the cam-wheel, and working' between the sections S', and the armsf are conzo neeted with the pivoted pitmen U and U", which are connected with the upper and lower cutter-bars, ll2 and U3, to which bars reciprocatingmotion thus ii'nparted.

A casing (indicated by V) is usually' pro- 2 5 videdfor the. operating mechanism.

UL1 is a front brace havingl a pivotal counection with the frame V at S3, and with the inner shoe, u, at s, the said shoebeing pivotally secured at its rear end to the outer 3o end of the coupling-arm Z, which is pivoted at its inner end to the frame V.

U5 is a thrust-bar pivotally connected with.

4o to its rear end the swath-board u2, carrying l the track-clearer ai". This shoe .is adjustable in height .in the following' manner: ',lhe rear part ot' the runner W ot' the slice is turned upward and has a series olf apertures, u', and it may be drawn up or moved down and secured at the desi red point by means ot' a screw, io', passed through an aperture, u', and screwed into the linger-bar X, the height ot' the shoe l Z2 indicates a tilting lever placed on the coupling-arm Z for the purpose of raising the points ot' the guard-lingers to avoid obstructions or to turn them downward as desired.

le claiml.. lu a mower, the con'ibination, with the axle having'a threaded end, of the `groundwheel K, provided with a hub having the annular ilanges 7o standing out from both sides thercot', the ratchet wheel l, recessed and seated on the flange t' on the inner side of the hub, the spring-controlled pawl k2, arranged to engage said ratchet-wheel, and the recessed ln ut G,screwed upon the extended and threaded end oli the axle and provided with a circum fercntial. flange that embraces the jflange 7s on the outer side ot the hub and bears on the peri phery of the latter, substantially as specified.

2. ln a mower, the combination of the main axle or shaft having the ground-wheels attached, the `gear-wheel L, seated loosely on said axle and having its hub Z forming' one section of a clutch, the opposite section, m, of said clutch splined or feathered on said axle and provided with a circumferential groove, the pivoted and forked lever M, having' the pin mi on its outer or rear end and the pin m on the arms of its fork, which pins project in to the circuinferentizill groove of the clutch part or section fm, the pivoted lever il, provided with the inclined or diagonal slot n, and the pin n", the coiled spring' o, connecting' the pins mit and a', andthe pivoted lever-handle l), havingI its l'ront end within easy reach of the dri vers seat, substantially as specified.

The combination, with the cam S, composed o'tf two sections havingwaved facing edges that would lit upon each other it' the sections were brought into contact, which sections are seated on the shaft R, the tapered openings through said shaft and through the outstanding bosses ot' said sections, and the l'aljiered adj listing-keys r2', of the centrally-piv oted shaft 'l`haviug' anti-friction rollers on its ends enter-iney between said sections, the pitmen U U,connected to the respective ends oi' said lever T, and the cutter-bars attached to the ouler ends oi' said pitmen.

l In testimony whereof we allix our signatures in presence of two witnesses.
