SPECIFICATION forming part of Letters Patent No. $91,514:, dated October 23, 1888.

Application filed March 22, 1888. Serial No. 268,143.

To all whom it may concern:

Be it known that I, ALONZO P. COOK, a citizen of the United States, residing at Attica, in the county of Wyoming and State ofNew York, have invented a new and useful Improvement in Mowing-Machines, of which the following is a specification.

My invention relates to an improvement in mowing-machines; and it consists in the peculiar construction and combination of devices, that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a mowing-machine embodying my improvements. Fig. 2 is a top plan view of the' same. Fig. 3 is a front elevation. Fig. 4. is an inverted plan view. Figs. 5 and 6 are detailed views. Fig. 7 is a detailed perspective view of the frame. Fig. 8 is a detail View of the rear end of the tongue.

A. represents the frame of the machine, which is made of one solid integral casting, comprises the inclined platform B, having the spindle 0 formed at its ends for the driving-wheels, is provided at its front side near its center with a pair of forwardly-extending downwardly-inclined arms, D, which are connected at their front ends by a crossbar, E. The frame is also provided at its ends with a pair of forwardlyextending downwardly-inclined arms, F, and has at a suitable distance from one end an arm, Gr, provided in its upper side with a longitudinal recess or groove, H, adapted to receive the beveled inner end of the tongue 1'. Formed integrally with the said frame or platform, on the under side thereof, is a transverse depending strengthening-rib, K, which is arranged in line with the spindles O, and a pair of forwardly-extending ribs or braces, L,which are arranged under the arms D.

H represents apair of traction drive-wheels which are journaled on the spindles G,and concentric with said drive-wheels and secured to the inner sides thereof are internally-spurred gear-wheels N.

0 represents a driving-shaft, which isjournaled transversely under the frame at a suitable distance in advance of the rib or brace K in bearings 0 which are secured to the arms F, and is provided at its extremities with gearpinions P, which engage the gear-wheels N, and are connected to the shaft by the usual (No model.)

pawl-an'd-ratch et mechanisn1,whereby the said pinions are caused to rotate with the shaft when the machine is moved forward, and are adapted to rotate idly on the said shaft when the machine is moving backward, or while it is being turned. These pawl-and-ratchet mechanisrns are not fully described herein, for the reason that they are of the usual construction and are well known to persons skilled in this art.

Rigidly secured to the drivingshaft O is a clutch, R, having studs S, projecting from its inner side at diametrically-opposite points. Loosely journaled on the said driving-shaft and arranged between the arms D is a gearwheel, T, which is adapted to slide on the shaft, is provided on one side of its hub with recesses U, adapted to be engaged by the clutch when the wheel is moved againt the same, and is provided at its opposite side with an annular groove, V.

WV represents a lever, which is fulcrumed on a substantially vertical spindle, X, that projects from the upper side of the frame, and the front end of the said lever extends downward and is caused to engage the annular groove V, the rear arm of the lever being adapted to engage a stop, Y, which is secured to and projects from the upper side of the frame. A spring, Z, bears downward on the central portion of the lever, and thereby keeps the same in engagement with the stud or step.

A represents a countershafmwhich isjournaled in suitable bearings secured on the un der sides of arms D. To the center of this counter-shaft is rigidly secured a pinion, B, which is adapted to engage the gear-wheel T, and to the ends of the said counter-shaft which project beyond the outer sides of arms D are rigidly secured a pair of disks, 0, which have inwardly-extending rims that are scalloped or sinuated in form, and thereby form serpentine cams D.

, Depending from the front ends of the arms D and formed integral therewith are arms E, and to the front sides of said arms E is bolted a transverse plate, F, which has a longitudinal central slot, G, and is provided on its inner side with a longitudinal groove, H, which coincides with similar grooves on the outer side of arms E, and thereby forms a guide for a reciprocating arm, I. The ends of the said bar are provided with antifriction rollers K, that engage the opposing edges of cams D, and thereby when the counter-shaft is rotated the bar I is reciprocated, as will be very readily understood. From the front side of the said bar, at the center thereof, projects a stud or spindle, L.

M represents an arm,which has its rear up per end pivoted or hinged to a depending ear, N, at one end of the frame by a pivotal bolt, 0. The lower end of this arm projects forward from the frame, is bent at such an angle as will cause it to lie horizontal above the ground when the machine is in operation, and to the front end of said arm is journaled asupporting roller or caster, P. The said arm M supports the inner end of the usual cutting apparatus, R, and the cutter-bar of said apparatus has its inner ends connected to the stud or spindle L of the reciprocating bar I by means of a pitman, S. v

T represents a link which connects the arm M with one of the arms E.

U represents a bell-crank lever, which is pivoted to one side of the tongue, near therear end thereof, and is connected to the arm M by means of a chain or flexible link, V. By operating the said lever the said arm N may be raised or lowered, so as to raise or lower the cutting apparatus, as will be readily understood. In order to secure the said lever in any desired position,the same is provided with the usual spring-actuated bolt, which engages a segment on the tongue. The usual drivers seat, a, is secured to a spring-bar, b, which has its lower front end secured to the frame;

The operation of my invention is as follows: When the lever V is moved so as to throw the wheel T in engagement with the clutch on the drivingshaft and the machine is drawn forward, the said wheel T is rotated by the driving-shaft and transmits rotary motion to the counter-shaft A through the pinion B, and thereby causes the cam to rotate and reciprocate the bar I, the motion of the said bar being communicated to the cutter-bar by the pitman before described. When the lever IV is moved so as to bring the wheel T out of engagement with the clutch on the driving-shaft, the latter rotates without rotating said wheel T, and consequently the cutting apparatus is thrown out of gear.

I would have it understood that I may employ my combination of gearing for working the sickle or cutter-bar on any form of mowing-machine,whatever may be the style or construction of frame.

I do not wish to be limited to form, proportion, or details of construction.

Having thus described my invention, I claim 1. The combination, in a mowing-machine, of the frame having the forward projecting arms D and the bar E, connecting the front ends of said arms, the traction-wheels having the gears N, the driving-shaft journaled in hearings in arms D and having the wheel T and'pinions P, the latter engaging gears N, the counter-shaft A,parallelwith the driving shaft and also journaled in bearings in arms D, and having the pinion B, engaging wheel T, the cams D, secured to the ends of the counter-shaft and arranged opposite each other, the guideplate F, secured to the front ends of arms D, the reciprocating bar I, sup ported in the plate F and engaging the opposing sides of the cams, the cutting apparatus having the finger-bar connected to the frame and the cutter-bar, and the pitman connecting thelatter to the bar I, substantially as described.

2. The combination, with the frame of a mowing-machine, of the revoluble shaft A, mounted therein, the disks 0, secured to said shaft and having the inward-projecting rims constituting the cams D, the guideway arranged between the said cams, the reciprocating bar I in said guideway having its end engaging the opposing sides of the cams, the cutting apparatus comprising the finger-bar and cutter-bar, the former having its inner end pivotally connected to an arm of the frame, and the pitnian connecting the cutter-bar to the bar I, substantially as described.

3. The combination, in a mowing-machine, of the frame having the forward-projecting arms D, the driving'shaft journaled in the frame and having the wheel T, the counter.- shaft journaled in arms D and having the pinion engaging wheel T, and provided with the cams D, arranged opposite each other, the guide-plate F, secured to the front ends of arms D, the reciprocating bar 1, arranged in a groove in said guide-plate and engaging the opposing sides of the cams, the cutting apparatus having the cutter-bar,and the pitman connecting said cutter-bar to the reciprocating bar I, substantially as described.

In testimony thatI claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

ALONZO P. COOK.
