SPECIFICATION forming part of Letters Patent No. 439,253, dated October 28, 1890.

Application letl January 6 1890. Serial No. 336,101. (No model.)

To all whom it may concern,.-v

Be it known that I, OLIVER U. PERRIN, a citizen of the United States, residing at Stone Blus` in the county of Fountain and State of Indiana, have invented an Improved Mechanism for Operating Flowing-Machines, of which the following is a specification.

My invention relates particularly to animprovement in reciprocating mowers, and has for its object to produce a machine of the character described, in which the operating mechanism is very simple, durable, and cicient.

With these objects in view-my invention consists in the peculiar construction ofvarious parts and their novel combination, as will be more fully explained hereinafter.

In the drawings forming a part of this specification, Figure l is a perspective view of my improved machine. Fig. 2 is a top plan view. Fig. 3 is a detail view of the wheel and ratchet. Fig. 4 is a detail view of the shoecoupling, hand and thumb levers, pawl, ratchet, ne.

In the embodiment of my invention I use a main frame A, essentiallyT rectangular in shape, said frame being of wood or metal, and connected with the opposite sides of said frame are the journal-boxes A', through which passes the axle A2, upon the ends of which are mounted the drive-wheels A3. The axle-spindles are provided with the ratchetwheels d, and the hub of each of the Wheels is formed with a recess adapted to receive said ratchet-wheeland also a spring-actuated pawl pivoted to said hub and adapted to engage the ratchet. By this construction the axle will be rotated when the Inachine is moving forward, but will not move when the machine is backed.

A wheel B is rigidly secured to the axleshaft within the main frame, one face of said wheel being serrated radially, as shown at b, and upon the axle adjacent to the serrated side of the wheel is arrangeda rigid collar B', in which the axle turns, and in which is pivoted the vibrating lever C, the axle passing through said lever or not, as desired. The wheel B has an uneven number of serrations, and the face of the lever C that rests against said wheel is formed to correspond with said serrations. The lever has no vertical movement, and is vibrated horizontally by the serrated wheel B, with which it is in engagement.

outer end of the shaft F, said coupling having a lever G rigidly connected therewith at its top and extending inwardly toward the driver, said lever having a thumb-lever g, which operates a spring-actuated pawl g', which is pivc-ted to the shoe-coupling and adapted to engage the ratchet-faced enlargement f and hold the coupling at any desired angle. H indicates the shoe, and H the finger or guide bar, and H2 is the reciprocating cutter-bar. H3 indicates a link-connection between the draft-pole and shoe. The outer end of the vibrating lever is formed with a ball, which fits into a socket in the end of the pitmanrod I, and is held in said socket by means of the socket-cap 'L'. The outer end of the pitman is also 'provided with a ball, which tits in a socket-cap i2, secured to the cutter-bar. A lever K is pivoted to the upper side of the frame near the drivers seat, said lever having a link-arm 7c connected therewith, which in turn is connected with a'chain or rope 7c', attached to the coupling-yoke, and by elevating or depressing the leverV the coupling, cutter, dac., vare raised or lowered. The chain passes over a pulley or sheave k2, mounted on the side of the frame. By means of the hand and thumb levers the cutter-bar can be arranged at any suitable angle.

S indicates the drivers seat. ,if

The operation and advantages of y improved device are obvious to every one in the art to which it pertains.

What-I claim as new, and desire to'secure by Letters Patent, is-

`kines In a mowing-machine, lthe combination, with the main frame having the tubular axlebeariugs projecting laterally from both sides of the frame, of the axle passing through said 5 bearings, the rigid collar mounted. loosely upon the axle between the tubular bearings, a ratchet-faced Wheel secured upon the axle within the frame, and adapted to turn with the said axle, and a vibrating lever pivoted :inl the rigid. collar ami adapted to engage the so ratchet-faced wheel, substantially as shown and described.
