MOWlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 509,317, dated November 21, 1893.

Application filed April 1 3. 1 8 9 3.

To all whom it may concern.-

Be it known that I, JOHN W. LATIMER, of Milwaukee, in the county of Milwaukee and State of ViTisconsin, have in vented certain new and useful Improvements in 'Mowing-Machines; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which itpertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The main objects ofmy invention are to prevent the dragging of the cutting apparatus and thereby diminish the direct draft and avoid side draft of the machine; to take the weight of the cutting apparatus off from the horses necks when the machine is not in operation; to utilize the weight of the driver or the draft of the team or both, to sustain the weight of the cutting apparatus, and-at the same time hold the finger bar steady and avoid the communication of abrupt movements or variations in weight or draft through the intermediate connections between the seat or draft and the cutting apparatus.

It consists essentially of a seat support movably connected with the frame and having an elastic connection with the cutting apparatus; of an elastic connection between the draft connection-and the cutting apparatus; of a longitudinally and laterally movable gear shaft in connection with internal and bevel gears, and of certain other novel features of construction and arrangement hereinafter particularly described and pointed out in the claims.

In the accompanying drawings like letters designate the same parts in the several figures.

Figs. 7 and 8 are respectively a plan view and side elevation on an enlarged scale showing a modification of the seat support and of the draft connection with the cutting apparatus; and Figs. 9 toll are detail views showing another modification of the seat support and draft connections, Fig. 9 being a partial side, elevation and vertical cross section, Fig. 10 a vertical section on the line 10,10, Fig. 9, and Fig. 11 a plan View.

A represents the frame of the machine, which in this case comprises a tubular portion a, through which'the main axle passes, a tubular portion a at right angles thereto, through which the fly wheel or crank shaft passes, and a tongue support (1 B B are the main supporting and driving wheels mounted in the usual or any suitable manner upon the ends of the main axle O,

with which they have the usual ratchet con-- nections.

D is an internal driving gear fixed upon the main axle C on the opposite side of the machine from the cutting apparatus.

E is a short driving shaft parallel with the main axle, provided at one end with apinion e, constructed and arranged to mesh'with the driving gear D and provided at the opposite end with a bevel gear e.

F is the fiy wheel shaft supported in the tubular portion a of the frame, and provided at its rear end with a bevel pinionf, arranged to mesh with the gear e. It is provided at its front end in a suitable housing formed by an extension of the frame, with afly or crank wheel f, which is connected in the usual or any suitable manner by a pitman f with the knife or cutter. The driving shaft E is supported in an eccentrically bored sleeve G, which in turn is held in a sleeve H, cast with or rigidly attached to the main frame, behind and parallel with its tubular portion or. The sleeve G is provided with a rod or arm g, projecting outwardly therefrom through an incline or cam slot h in sleeve H, shown in detail in Fig. 4. By turningthe arm 9 backward, the shaft E is simultaneously shifted laterally forward toward the main axle and moved'endwise toward the center of the machine, thereby carrying the pinion e out of engagement with the internal driving gear D, and the gear 6 away from the pinion f. With the arrangement of gears herein shown and described, it is necessary for the purpose of moving the pinion 6 out of engagement with the gear D, to move the driving bevel gear e, away from its driven pinion f, otherwise the gear 6' would bind upon the pinion fand prevent the disengagement of the pinion e from the gear D.

The device above described affords simple and effectit e means for connecting and disconnecting the driving gearing at a single operation.

I is the coupling bar pivotally connected at one end to the front part of the frame in line with the crank shaft F, and at its opposite end by a yoke J with the shoe J, to which the finger bar J is attached. The yoke J is formed with a sleeve which encircles and is capable of turning on the coupling bar I and is forked and hinged or pivoted by its arms to said shoe in a line parallel with the draft of the machine.

j is a push bar or brace loosely connected at its rear end with a depending arm or bracket to the frame, and at its front end with the sleeve of yoke J.

The supporting or carrying connections of the finger bar hereinbefore described, constitute no essential part of my invention, but are shown and described as suitable for use in connection with my improvements, as they allow the cutting apparatus to conform freely in its movements to inequalities in the ground and permit of the desired tilting, elevating and folding adjustments or movements necessary or desirable in a machine of this kind.

K represents the seat support, which is hinged to the rear side of the tubular part a of the frame by means of a rod or bolt L, passing through perforated ears formed on said frame and support, as shown in detail in Figs. 5 and 6. It is formed or provided with an upwardly projecting arm 70, a downwardly projecting arm is and a rearwardly projecting plate 15 to which the seat L is adj ustably attached, a number of holes being provided in said plate for the purpose, as shown in Fig. 6. By setting the seat farther back or forward, the leverage of the weight of the driver upon the seat support, which with its arms constitutes a lever, is increased or decreased.

10 is a dog pivoted to the seat support and arranged to be turned between it and the frame, as shown in Fig. 5, for the purpose of locking said support rigidly in place with the frame in case for any reason it is desired to prevent the lifting operation of the driver or seat and the draft, through the spring M.

The upwardly projecting arm 7r; is connected by a spiral spring M with the upper part of a quadrant lever N, pivoted to a bracket attached to the pole or to any convenient support, and in turn connected bya chain nwith one arm of a bell crank lever O, fulcrumed at its angle to the sleeve of yoke J, as shown in detail in Fig. 3. The other arm of said lever is connected by a chain 0 with the upwardly extending arm of a lever P, fulcrumed upon a pin or bolt 10, to the shoe J in the line of its hinge or pivot connections with yoke J, and formed with a short angular arm which bears upon the inner end of the finger bar or a portion of the shoe. The weight of the driver acts through the seat support K and the connections last above mentioned, primarily upon the coupling bar I, tending to lift the shoe J and inner end of the finger bar, and secondarily through the lever P, tending to lift the outer end of the finger bar. In this way the drivers weight tends to counterbalance the weight of the finger bar and to prevent its dragging heavily upon the ground.

The chain it is connected with the quadrant N through the medium of an angular lever n, fulcrumed by its shorter arm to said quadrant at an intermediate point in its periphery, and having its longer upwardly extending arm curved to correspond with the curvature of the adjacent portion of the periphery of said quadrant. A foot lever B, fulcrumed to the upper side of the tubular portion a, of the frame within convenient reach of the drivers right foot, is connected by a rod 7 with the upper end of the lever n, and serves to lift the shoe J and the inner end of the finger bar, to pass over obstructions or for any other purpose. A hand lifting lever S, fulcrumed to the frame concentrically with the lever B, is arranged when swung backward to engage with a shoulder r on the lever B, and through it to lift the shoe J. The driver is thus enabled by either hand or foot to raise the cutting apparatus. The lever 41 serves also as a stop to limit the expansion of spring M and the descent of the shoe J, thereby preventing it from dropping too far into holes or abrupt depressions over which the machine may pass, the upper end of said lever n being held rigidly in place by its connection with levers R and S. The downward movement of the quadrant N is arrested when its periphery comes in contact with the upper portion of said lever. I utilize the draft of the team also, either alone or in connection with the weight of the driver, to counterbalance the cutting appara tus, by connecting the evener Q, which is loosely suspended from or movably connected with the pole, by a draw bar (1, with the downwardly projecting arm k of the seat support K. The draft of the team is thus transmitted through the seat support and its connections hereinbefore described, to the cutting apparatus, which it tends to lift from the ground.

To adjust the tension of spring M, I provide for its attachment at one end, a hooked rod m, having a screw threaded plug m, as shown in Fig. 5, which may be turned into or out of said spring more or less as desired.

The upwardly projecting arm of lever P is formed with a series of holes, as shown in Fig. 3, and by shifting the attachment of chain 0 fication of the seat support and draft connec-' tions designed to utilize the draft of the team alone for sustaining the cutting apparatus, K represents the seat support, which in this case is cast with or rigidly attached to the tubular portion a of the frame. A rod or shaft L, supported and capable of turning in bearings between and parallel with said seat support and frame, is provided with a depending arm Z, with which the draw bar q is connected, and with an upwardly projecting arm Z with which the spring M is connected. A dog Z pivoted to the frame, is arranged to be turned into engagement with a shoulder on arm Z and lock the same rigidly with said frame, so as to prevent whenever it is desired, the operation of the draft connections upon the cutting apparatus. T is the tilting lever, which is connected by a rod t with an upwardly projecting army" on the sleeve of yoke J, for the purpose of tilting the finger bar or turning it on an axis in the direction of its length. This lever is f ulcrumed to the depending arm or bracket with which the rear end of the push bar is connected, and is provided with the usual latch, which works with a quadrant t, formed with or attached to said arm or bracket. The seat sup port K is constructed to serve as a foot rest, as clearly shown in Fig. 2.

Referring to Figs. 9 to 11 inclusive, illustrating a modification of the seat support and draft connection, whereby the range of independent movement of the seat on its hinge connection with the frame and its leverage on the cutting apparatus are reduced, K is the seat support, which is hinged or pivoted by cars formed thereon to corresponding ears a (t formed on the tubular portion a of the frame, parallel with the axle O. U is a casting pivoted on a line parallel with the axle C to ears 0. a on the frame below the seat support and formed with depending ears or arms u u, which are connected by a link 10 with the rearwardly projecting attachment plate of the seat support. It is also formed with an upwardly projecting arm a with which the spring M is connected, and a downwardly projecting arm U2 with which the draft bar q is connected. The yielding or elastic connection afforded by the spring M prevents the transmission of abrupt movements or vibrationsfrom the finger bar to the seat and draft bar, or vice versa, when the machine is passing over rough or uneven ground. The finger bar is thus carried more steadily and the seat is caused to ride more comfortably and with greater safety to the driver, as any sudden drop of the finger bar when it passes over an abrupt depression, willnot be transmitted to the seat. Besides, when the main wheels run into holes, producing a sudden and violent depression of the seat, the increased draft exerted'through the draft bar in drawing the machine out of such holes, is applied to the support of the cutting apparatus just at the time when the ,recoil of the seat relieves it of the drivers weight and would otherwise allow it to drop.

Various other changes in minor details of construction and arrangement may be made within the intended scope of my invention.
