UNITED y STATES P.A "rniwiv OFFICE.

y JOHN HLRIBLE, or DAYTON, OHIO.

Y IIVIPROVEIENT IN MOWlNG-MACHINES.

Specification `forming part of Letters To aZZ whom it maycmwern:

Be it known that I, J OHNH. BIBLE, of the town of Dayton, in the county of Montgomery, State of Ohio, have invented new and useful Improvements in VMowing-Machines; and the following is a clear and exactn description of metal frame detached.

My invention consists in the arrangement of the journal-boxes which support the crankshaft, in combination with the draft-pole and the brace-bars which support the cutting mechanism, in the manner herein fully set forth, so that by raising the cutter-bar to a given height the pinion is disconnectedfrom the gear-wheels, thereby dispensing with all other fixtures for stopping the motion of the cutters.

To enable others skilled in the art to make and use my invention, I will proceed to describe it more fully, referringto the drawings and the letters marked thereon. v

My mowing-machine is constructed in the most simple manner by a metal frame, A, so shaped as to form the boxes a a, for the driv! ing-shaft B', which supports the machine on two wheels, b` b. At right angle with the boxes a a are bosses c c', into which is iitted a'pinion, C, working into a bevel-gear wheel, D, secured to the axle-shaft B, by which motion is communicated to the long crank-shaft d by the intervention of the spur-gear wheel E and pinion e.

The crank-shaft d has its support and bearings at each end in boxes f andf, to which the brace-bars H and I are fastened. The journal-boxes f and ff are hinged on boltsV or screws ii to the angle-pieces jj, on the extreme ends of the frame A, and are placed enough out of the line of the center with the shaft cl to allow thepinion e to be released from contact with the gearewhel E when the cutterbar is elevated to a certain point, and

| will always be thrown into and held in gear when the cutter-bar rests on the ground.

The back brace-bar, H, is secured to the box f', and connects at the bottom with the shoe K at its rear end. The front brace-bar, I, is also secured to about the center of the shoe K, and is so bent edgewise as to extend away forward under the axle B, and connects with the journal-box f under the drivers foot-piece h, which is placed on the tongue or pole F. The brace I greatlystrengthens the cutting it being extended forward of theline of the periphery of the driving-wheels.

of the metal frame A, and extends back so as to about balance on the axle-shaft B. On it is placed the drivers seat G, mounted on a Springbar, g.

The cutting mechanism is arranged to follow in the rear of the driving-wheels, and consists of the shoe K, to which the guard-finger bar L is hinged by screw-pivots k k, so as to allow the whole to turn up and` over and rest on the rear end of the pole when not in use. The guard-fingers ZZZ, the scallop cutters m da, the dividing-finger a, and track-clearer o differ not in construction from those in common use.

. Attached to the axle-shaft B is a crooked hand-lever, J, connected to the brace I by a link or chain, q, for the purpose of elevating pass over stones and other irregularities, as

its motion. This arrangement is found to be simple and efficient for the purpose of connecting'and disconnecting the gear to operate the bar is resting on the ground for mowing.

The great desideratum in all labor-saving machinery is to have it as much simplified as possible- 1'. e., to have as few pieces to effect the purpose as can be made to answer, and the fewer the number of bolts and screws to put work together the better, and none more so than agricultural implements, which are subject to .strain and jarring in passing over the irregular surface of the soil, and, moreover, are generally in the hands of men who have but little practical knowledge and experience in mechanics. Thus it will be seen mechanism, and the side draft is equalized by The pole or tongue Fis secured to the top `the cutting mechanism and controlling it to also to throw the pinion out of gear and stop the cutters, and is sure to be in its place when y that the peculiar simplicity of my machine have their bearings, in combination with the cannot fail to be comprehended in al1 its parts, draft pole or tongue of the machine, and With so that any further explanation is deemed unthe braces H and I, which support the cutting necessary. mechanism, substantially in the manner and Having thus fully described my improvefor the purposes herein set forth. ments, what I claim as new, and desire to se- J.
