Patented Apr. 15, 1930 i N UNITED STATES PATENT OFFICE ERNEST SACK, OF WAVERLY, IOWA RAILWAY MoWEn Application led December 1, 1927. Serial No. 237,037.

My invention relates to improvements in tion of the frames 11 and 1 as shown. Lon` railway mowers, and the object of my imgitudinal bars 16, 17 and 18 are end-conprovements is to furnish a self-propelled denected to and across said arched intermediviceof this class, equipped with a laterally ately located bars 15.

An internal coina reciprocable sickle device of a well-known bustion engine 5 is mounted in the front part type mounted upon it and has the usual end of the chassis and drives a rotary shaft 6 ShOeS at at 29.

Other arched members 15 are following described means. The numeral 34 fastened rigidly across the bars 12 of frame denotes an arm swingingly mounted upon the 0 1 a little outside of the frame 11 in the posiarch member 14, the latter having a link 33 and cable connection 32 to a short erect arm 30 fixed on the shoe 29. A cable 35 is end connected to the member 14 and has its other end connected to and to be wound upon a drum-shaft 37 which is rotatably mounted in bearings on the bars 12. The shaft 37 has at the. rear a hand crank 41 andl a ratchet wheel 47 thereon, the latter' engageable by a gravity controlled pawl. A cable 39 is end connected to the front end ,of the shoe 29, thence passed forwardly oblique-ly about a sheave L10 on the forward right hand corner of the frame 1, thence rearwardly and about a sheave on said frame and then to the left and end-connected to a pulley 38 on the shaft 37 to be wound thereon. A third cable 42 is end connected to the arched member 13 and also end connected to the shaft 37 to be wound thereon.

The operator standing on the frame platform 11 may control the to and fro lateral movements of thevframe 11 byfrotatingr the crank 41 with the shaft 37 to wind the cables 35 and 42 reversely thereon, and thus the frame may be projected tothe left from the position shown or after a cuttingof a parallel outer swath. The sickle-bar 31 may be swingingly controlled by the arm or lever 34, the arm being left loose to let the shoes 29 ride upon the ground when mowing, or the arm 34 may be swung to erect the sickle-bar to clear whistle-posts in the way. The loose- 1y swinging sickle-bar-may react to avoid stones or small obstacles in the way by swinging a little over them upwardly.

The cable 39 cooperates with the cable 35 in the propelling of the frame 11 or returning of the same, and also in taking up side draft thrust, and the mounting of the frame 11 is such as also to almost entirely eliminate side draft thereon.

When parallel swaths have been cut alongside the rails 4 on one side of the right of way, and the chassis has been reversed in direction at the end of its run, the other side of the right of way may be similarly mowed over. The arm 34 may be completely-swung over to the left, erecting the sickle-bar 31 when not in use, and the arm then sprung into a hook 3G on the right-hand bar 15.

The lever 20 is used in the usual way in clutching the sleeve 8 to the hub of the sprocket-wheel 10 incausing rotation of the Wheel and movement of the chain 21 in moving the frame 11 laterally to the right, the shfaft 37 being used in returning it to the 1e Having described my invention, what I claim as new and desire to secure by letters patent, is:

1. In combination, a wheeled chassis, mechanism mounted thereon for propelling it, an elongated frame movable across and upon said chassis to different positions of lateral adjustment, a sickle-device mounted terminally upon said frame to be swung vertically, means for actuating the sickle of said device disconnectibly operatively connected to said propelling mechanism, a cable connected to said sickle-device for eliminating side draft thereon, and a winding-drum on said frame upon which the cable is windable..

2. In combination, a wheeled self-propelled chassis, a hingedly connected sickledevice and transversely mounted frame support therefor, the frame being mounted upon said' chassis for lateral adjustments thereon to permit the sickleY device to be projected laterally beyond the chassis to cut swaths at different distances therefrom, and manually operable means for supporting movably the sickle-device relatively to said chassis to. eliminate side draft thereon, consisting; of a winding-drum on the frame, an idler pulley in advance of the sickle-device on thev for-l ward part of the frame, and a cable windable upon said drum, reevedv upon said pulley and' end connected to the forward part of the sickle-device.`

3. In combination, a wheeled chassis, a'.

prime motor mounted thereon, an elongated frame movable across the-chassis oppositely,

a sickle-device mounted upon an* end of the frame to swing vertically, disconnectible means for actuating tlie-sickle-device driven by the prime motor, means connected to said' frame including a manually operable device for shifting it laterally oppositely, disconnectible connecting means between the-primemotor and wheels of the chassis for rotating the wheels, a winding-drum on the frame, a`

cable connected to the-sickle-device to prevent side-draft thereon, said cable being windable upon said drum, another cable windable on said drum and connected to the sickle carrying end of the chassis, and a third cable wound reversely on said drum and end-connected to the opposite end of the chassis.

4a. In combination, a wheeled chassis, a prime motor mounted there'onv and? disconnectibly connected to wheels-of the chassis, an elongated frame mounted upon the chassis to shift across it laterally oppositely,.a sickledevice mounted upon' one end of the frame' ERNEST SACK.
