IMPR'OVEMENT IN MOWERS.

Specification forming part of Letters Patent No. 211,163, dated J annary 7, 1879; application filed October 4, 1878.

To all whom it may concern:

Be it known that I, WILLIAM J. KLAUNIG, of Richmond, in the county of Henrico and State of Virginia, have invented a new and Improved Mowing and Reaping Machine, of which the following is a specification In theaccompan yin g drawings, Figure 1 represents a sectional side elevation of my improved mowing andreaping machine. Fig. 2 is a top view of the same; and Fig. 3, a detail view, on enlarged scale, of the wave-wheel.

Similar letters of reference indicate corresponding parts.

The invention relates to an improved construction and arrangement of parts, as here-- inafter described and claimed.

Referring to the drawings, A represents the knife-bar-supporting f ame, which is cast ofone piece of metal, and hung by sleeves to the axle of the mowing or reaping machine.

Between the curved and forkshaped portions of frame A is placed, on the axle, the wavewheel B, which transmits the power, by a fulerumed lever, G, and pitman D, to the knifebar E.

The supporting-frame A is grooved for the lever G, and braced by a straight arm, A, extending from the longer axle-sleeve, near one of the supporting-wheels, to the front end of the frame. A curved guard-shield, a, at the front end of frame A protects the pitman-connection with the knife-bar.

The wave-wheel B, which imparts the motion to the knives, is placed loosely on the axle, and thrown, by means of a clutch arrangement, B, in or out of gear with the same. The wave-wheel is cast of two disk-shaped sections, which are bolted together, and so indented at the circumference as to form a me andering guide-groove for the pin or roller of the transmitting-lever C.

'The groove of the wave-wheel is so constructed that the points'or apices of the bonds are elongated, and the corresponding guide portions of the disk-sections flattened off, as shown in detail in Fig. 3. In the full-sized working machine the apioes of the points measure about two and a half inches across. This causes a shorter or longer stop of the knives whenever the pin of the lever passes that part of each bend or wave between the elongated point and the corresponding fiattened-off guide portion.

The knives of the knife-bar have to bemade shorter or longer in proportion to the shorter or longer stoppage of the pin in each wave of the wheel. This peculiar shape of the wavewheel imparts to the knives a scythe-like cutting action, that prevents the dropping of the grain from the cars, which has hitherto been the case, owing to the rapidly-reciprocating motion of the knives of former machines, which motion shakes out the grain, and compels, therefore, the cutting of the grain before it has become entirely ripe.

By my wave-wheel a slower motion of the knives, and a position of rest beforethey move in opposite direction, are obtained, which admits the filling up of the spaces between the knives with stalks, which are out easily, and without being shaken, so as to drop the grain.

The lever O is retained by a screw-plate, b, near its fulcrum in frame A, and receives its motion by the usual pin or roller d at the rear end from the wave-wheel. An arm, G, ex tends at right angles from the lever O, and swings in a side groove of frame A. The arm 0 has a weight at its outer end, that exerts, in connection with the swinging motion of the lover, a kind of sudden end motion on the knives, giving it somewhat of a hammer motion for effectively cutting off the grain.

The front end of the lever O is connected to the pitman by aball-and-socket joint, 6, the ball being at the end of the lever, and a sectional box, 6, at the end of the pitman, so that the pitman moves freely and flexibly on the end of the leverl The opposite end of the pitman is attached by a hook-connection. to an eye, f, of the knife-bar. This forms a simple connection of the pitman with the transmit ting-lever and knife-bar, and supplies, in con nection with the frame and wave'wheel, a simple and durable knife-motion for mowing and reaping machines.

I do not claim a wave-wheel made in two parts; and I am aware that a cam-wheel having a slot or groove, one portion of which is straight and the remainder spiral, has been used for operating the rake of a grain-har vester.

Having thus described my invention, Iclaim tending at right angles from the lever, substantially as and for the purpose described.

3. In a mowing and reaping machine, the combination of a wave-whee1,B, and transmitting-lever 0, having weighted arm 0, with pitman D and knife-bar F, the transmitting-lever and pitman being connected by ball-andsocket joint, and the pitman hooked to an eye of knife-bar, substantially as set forth.
