IMPROVEMENT IN MOWING-MACHINES.

Specification forming part ol' Letters Patent No. 16,274, dated December 23, 1856; Reissue N0. l,210,f dated July 9, 186i.

looking in the direction of' arrow l, Fig. 1.'

Fig. 3 represents a rear view, the finger-beam being shown in red lines elevated at its outer end; and Fig. 4t represents a side view of the ad justing-plate M, together with certain other portions of the machine, the plate M- being shown in ditt'elentpositions by black, blue, and red lines.

In the drawings, A represents the main frame, the extension side pieces, A', answering the purpose of thills by which to guide and steady the machine, the draft connections being of any known form.. B B are the main su pportin g and driving wheels, fast to the axle C. B is a gear, fast to the main wheel next to the cutting apparatus, and gears with wheel ay fast on shai't c, and to which gear b is also made fast, whereby, as gear b is revolved, gear d, together with its crank-shaft e, are revolved. Crank-shafts e and g are connected by a link,f, so that as crank e is revolved crank g, which is greater than e, is caused to vibrate back and forth, thus giving a similar vibration to the crank It', to whose wrist the front end of the pitman or connecting rod I is attached. In this way the bent lever J, which is pivoted to the heel of the tinger beam. is caused to vibrate on its t'ulcrum,

` causing the cutter bar or bars 5 (i, between Vwhich the rear ends of the cutters are pivoted,

to move back and forth, whereby the front of the cutters, which are pivoted to the lingerbeam at 7c, is caused to vibrate back and forth between tingers or stationary cutters t' far enough to cut on each side, rst on one side and then on the other. The cutters are pivoted to the upper side of the linger-beam K, and work over theiedges of the fingers or stal tionary cutters i, which are provided with curved supports 7, as shown in the drawings, the rear ends of the supporters 7 being made fast i`n the bottom of the ringer-beam K. The top .of the linger-beam is formed with a depression, K, for the purpose of allowing the cutter-bar to work down low enough to permit the cutters to rest on the face ofthe stationary knives or lingers, which are fastened to the top ot' the linger-beam. By this construction and arrangement of parts the cutting apparatus is rendered quite compact and well protected from injury. A cap, l, is placed over the rear of the cutters to keep out cut grass. The finger-beam is formed of metal, and its heel is provided with an eye, whereby to hinge it between ears N N, which project from the side of an adjusting-plate, M. The main part of the adjusting-plate M is made in the form shown in the drawings, and hung to the side of the main frame by a hinge or bolt, 1, so that its ears N N, which support the heel of the finger-beam, will be close down to the ground. Plate M can be adjusted back and forth, as shown in different colors in Fig. 4. If allowed to swing on the hinge 1, it would adjust itself,vor, if desired, by means of the bolts and nuts 2 and 3 it can be held in any desired position to give the points of the guards a greater or less inclination, the plate being cut out for that purpose. This is often of great advantage, especially in mowing on land lwhich is uneven and cut up by furrows, since, it' the points of the guards or cutters on such land are lett turned down as low as when used on level ground, they are. liable to run into elevations of ground instead of running over them. In the use of a nger-beam in a mowing'machine -hinged to the grain side of the machine by one of its ends only, so as to be capable of rising and falling as these machines have heretofore been constructed, the linger-beam was arranged on a line back ofthe axis ot' the main driving and supporting wheels; consequently it became necessary to employ connections and coupling-pieces of considerable length in order to give the cutting apparatus the necessary freedom of motion when the machine was passing over uneven ground. By my arrangement, however, the nger-beamis so placed that it is nearly on a line with the axis ot' the supportingwow.

wheel, and consequentb7 the motions of the machine do not a'ect the position of the cutting apparatus so much as if it were arranged. farther back, hence there is not that necessity for long connections, which are more liable to break. By bringing the main frame down close to the ground and giving it the form of a runner it runs over mown grass which mayv happen to be close to the heel of the fingerbeam and presses it down, thus preventing its being rolled up in front of thev machine. The connection of vthe front of the pitman I with its Wrist is loose, so as not to cramp when the n ger-beamispassin g over uneven ground.

I-Iaving described one mode of applying my said improvements to practical use, what I claim, and desire to secure by Letters Patent, 1s-

1. The combination, with thc heel ofa iinger-beam so connected or hinged to the main frame of a mowing-machine as that the entire bar can rise or'fall independent of the Lip-anddown motion of the main frame of a selfadjusting hinged plate or auxiliary shoe, for the purpose of allowing the points of the guards or fingers to freely adapt themselves to the character ofthe ground over which the machine passes While in operation.

2. I do not claim, broadly, so constructing,` and connecting the inger'beam to the main frame ota mowingmachine as that the points ofthe guards can be adjusted up or. down, but I claim, in combination with a s lf-adjusting auxiliary shoe or plate, as set forth in the above claimof an adjusting screw or bolt, for the purposes stated.

3. The combination of the adjustable inetallic plate M with its ears N N, and other- Wise constructed as described, with the heel of the finger-beam and main frame, as set forth.

4. The combination of the bent lever J and its opcratin g mechanism and hinged oscillating cutters j with a hinged linger-beam, for the purposes stated.

In witness whercof I have hercunto subscribed myname.
