IMPROVEMENT IN MOWING-MACHINES.

Specification forming partof Letters Patent No. 20,164, dated May 4, 1858.

To all whom it may concern:

Be it known that I, HENRY MARcELLUs, of Amsterdam, in the county of Montgomery and State of New York, have invented a new and Improved Mowing-Machine; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specilication, in which- Figure l is a side sectional elevation ot" my improvement, taken in the line a' m, Fig. 3. Fig. 2 is back view of the same. Fig. 3 is a plan or top view of the same.

l Similar letters 'of reference indicate corresponding parts in the several ligures.

This invention consists in. a novel way of attaching the main frame of themachine to `its axle, as hereinafter fully shown and described, whereby the sickle is allowed to conform tothe inequalities of the ground withv out at all affecting the perfect operation of the driving-gear, and the machine as a whole rendered extremely simple and effective.

To enable those skilled in the art to fully understand and construct my invention,l will proceed to describe it.

A represents an axle. B Bare wheels tted thereon. The wheel B is litted loosely on-the axle, but the wheel B isattached permanently to it.

C is a sleeve or collar, which is placed loosely on the axle A, and adjoining the wheel l. This sleeve or collar has an arm or projection, a, attached to its front part at right angles.

D is the main frame of the machine, which is formed of a cast-metal plate, having the linger-bar E rigidly attached to its back end, at right angles with it., as shown in Fig. 3. 'lhe front end of the main frame D has a vertical ledge, b,'i'ormed on it, through which a journal, c, at the front end of the arm or projection a, passes loosely, and a journal, d, at the back end ofthe sleeve or colla-r C, and in line withjournal c, passes into an upright, c, attached to the main frame. (See Fig. l.) By this means the main frame is attached to the axle A, and it will be seen that a universal-joint connection is obtained-that is to say, the platform is allowed to vibrate or move vertically in a plane at right angles with the axle A, and also in a plane parallel or nearly parallel with it. j

F is a bevel-wheel, which is placed on the axle A, and secured permanently to it, adjoining the end ofthe lsleeve or collar C.

This bevel-wheel gears into a bevel-pinion, f, which is placedon a shaft, G, one end of which has its bearing in the upright, e. The opposite end of the shaft Gr has its bearingin an upright, g, which is attached t0 the main frame D at its back part. The back end of the shaft G has a toothed wheel, h, on it, said wheel gearing into a pinion, i, which is placed on a shaft, H, parallel with the shaft G, and having its bearings in the same uprights, e g. The back end of the shaft H has ac'rankpulley, l, placed on` it, said crank-pulley having a connecting-rod, J, attached to it, which connecting-rod drives the sckleK, which is placed on the linger-bar E. y

P is the drivers seat, which is attached to an upright, Q, at the front end of the main frame, and at one side ot' it, as shown in Fig. 2. t

From the above description it will be seen that as the machine is drawn along the iinger-bar, and consequently the sickle, will rise and fall to conform to the inequalities of the surface ot' the ground, the linger-bar being allowed to rest on the ground, the linger and main frame working or moving together, as they are rigidly connected, and the movenection ot' the main frame to the axle A. It will also be seen that the driving-gear F f ot' the main frame, as the axis of the pinion j is at all times in a radial position relatively with the wheel F.

By means of the plate L, lever N, and bar O the finger-bar and sickle may be raised and supported at the proper height, the two caster-wheels M. M retaining the linger-bar and main frame in proper positions.

`By this improvement the machine is rendered extremely simple, it being composed of but very few parts, and none that are liable to get out of repair.

Having thus described my invention, what l claim as new, and desire to secure hy Letters' Patent, is^

Attaching the main frame D 'of the machine to the axle A by connecting the frame, by means ot' journals c d, to the sleeve or col lar C, which is placed loosely on the axle A, substantially as and for the purpose set forth.

HENRY MARGELLUS.
