IMPROVEMENT lN MOWlNG-MACHINES.

To all whom it may concern:

Be it known that I, ANTHONY B. ALLEN, of the city, county, and State of New York, have invented certain new and useful Improvements in the Construction of Mowing-Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanyingdrawings, making part of this specification, and in which Figure 1 represents the plan of a mowingmachine embracing my present improvements. Fig. 2 represents the inner side elevation of the main frame, the finger-bar and cutters being represented in section. Fig. 3 represents the rear elevation of the same machine; Fig. 4, a detail view of the inner shoe and curved lever.

My invention relates more especially to that class of mowing-machines in which the fingerbar is hinged in such manner as to allow of its being folded over against the main frame, for the purpose of enabling the machine to pass through gates or narrow passages and for the more ready transportation of the same from place to place.

My improvement relates to the means for causing to turn on its hinges the inner shoe, together with the finger-bar attached thereto.

The object sought to be attained by my improvement is that the lever arrangement by means of which the finger-bar is to be operated, and which is so adapted as to turn the finger-bar upward to a considerable height, should not in any manner incumber the frame, nor otherwise be in the way when the fingerbar is folded against the main frame; and, lastly, my invention relates to a new and improved combination and arrangement upon the main frame of certain means or devices for actuating the lever which operates the fingerbar.

To enable others skilled in the art to make, construct, and use my invention, I will now proceed to describe it in detail, omitting the description of such parts of a mowing-machine as are not essential to the full understanding of my present improvements.

The main frame is represented as being supported on two large wheels, B B. To the under side of the inner beam, A and near its front end, are secured two arms, 0 O, the outer ends of which project from the main frame and are made to fit between lugs a, erected upon the inner shoe, I), to which the inner end of the finger-bar E is secured. In the lugs a are formed suitable holes, corresponding holes being also provided at the extremity of the arms 0 O, for the reception of bolts 1) b, by means of which the inner shoe is hinged to said arms. On the inner and rear end of the shoe D is formed a vertical projection, 0, against which is made to rest the inner side ofa lever, F. The rear bolt, b, serves as a fulcrum of this lever, and which is made of a curved shape, inclining outward, as shown in Fig. 4, in order that it should be capable of considerable play without interfering in the least with the inner frame-beam, A This curved lever F is operated by means of a chain, belt, or rope, G, secured to upper end of said lever. This rope, which passes first over a grooved segment, H, mounted horizontally in suitable bearings projecting from the inner frame-beam, A", has its other end secured to a grooved segment, H, mounted vertically on suitable bearings, J, which extend from the under side of the inner beam, A at a place next to the drivers seat M. This segment H is provided with a hand-lever, I, by means of which the driver is enabled to operate it. The stopsjj, which are arranged on the outer surface of the inner beam, A and on either side of the hand-lever, serve the purpose of preventing the latter from getting too much depressed. By operating the hand-lever I backward the segment H is caused to turn with it. The rope G, being thereby drawn in, pulls on the upper end of the lever F, which, pressing in its turn against the projection c of the inner shoe, forces the latter to turn on its hinges. WVhen the lever F has been drawn in against the frame-beam A the further lifting and folding of the finger-bar have to be effected by the driver pulling the end of the long handle L, which extends from the track-board and is suitably arranged for that purpose, and the lever F will remain'in the position as shown in red lines in Fig. 3.

The cutter-bar It receives its vibrating motion from the pitman Q, jointed to a projection, s, erected upon the prolongation r of the cutter-bar, said pitman extending from a crank, S, which receives its motion, through suitable intermediate gear, from the driving-wheel B. The end of the pitman next the cutter-bar is made to pass through an inverted stirrup, N,

made of metal or any other suitable material, supporting the inner end of finger-bar, the arand which is secured to the under side of the inner frame-beam, A as seen in Fig.2. This stirrup or checking contrivance, which is so arranged as not to interfere with or impede the necessary changes or variations in the position of the pitman in relation to the other parts of the machine,'wiil yet effectually prevent a too great depression of the said pitman and that of the inner end of the cutter-bar while the finger-bar is being lifted up or folded.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is as follows:

1. In combination with the pivoted shoe rangement of the lever F and projection c, in the manner substantially as and for the purpose set forth.

2. In combination with the lever F, operatin g as set forth the hand-lever I, the segments Hand H, and chain G, or its equivalent, the whole being arranged and operated in the manner substantially as and for the purposes set forth.

In testimony whereof [hereunto set m y hand.

ANTHONY B. ALLEN.
