To all whom it may concern.-

Be it known that we, E. FOWLER STODDARD and JAMES MODAVID RossnLL, citizens of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Mowing-Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings,

forming a part of this specification.

Our invention relates to that class of mowing-machines known as two-wheel front-cut machines; and its novelty consists in the construction, combination, and arrangements of 1 the parts, as will be herein set forth and specifically claimed.

In the accompanying drawings, Figure 1 is aside elevation of our improved mower with the near wheel removed. Fig. 2 is a correspending view showing the upward tilt taken by the finger-bar when dropped into a hollow or dead furrow. Fig. 3 is a plan view of the machine. Fig. 4 is a detailed plan view of the gearing. Fig. 5 is a side elevation of the bar- 2 lifting ratchet sheave and its connections.

, Fig. 6 is a reversed view of the same. Fig. 7

is a plan view of the same with the lever re- .moved. Fig. 8 is a detail perspective view showing the construction of the lower end of 0 thelifting-lever. Fig. 9 is an inside elevation showing the manner ofattach ment of the handlever to the ratchet-sheave. Fig. 10 is a detailed plan view of the eccentric counter-shaft. Fig. 11 is a side elevation, partly in section,

5 through the line a: :0 in Fig. 4. Fig. 12 is a front elevation of the machine. Fig. 13 is an enlarged detail view, partly in section, of the ring coupling, draft link, lever arm, I and coupling-bar.

The same letters of reference are used to indicate identical parts in all the figures.

A is the usual or any suitable main frame, supported upon the axle B,which is journaled therein, and which has the customary ratchet- 5 and pawl connections with the supportingwheels 0.

D is the pole or tongue, in this instance of two pieces, bolted together with a lapped joint and bolted or otherwise secured to the main frame.

The usual finger and cutter-bars, E and F, are connected to the machine in the following manner: I is a coupling-arm,whose extremity is connected by a ball-and-socket or universal joint, J, to the extreme forward extension of the main frame, and which isin aline slightly in advance of the finger -bar, but parallel therewith. The other extremity of this coupling-arm is joined with the yoke H, to the two arms of which the inner shoe, G, is pivoted. To the under side of the pole is secured a wellbraced pendent bracket, K, from the lower end of which extends a drag-bar or draft-link,

L, whose rear end is screwed, for purposes of adjustment, into the socket of a ring-coupling, 6 M, which embraces the coupling-arm I just at the side of the yoke H. This ring-coupling is held from slipping laterally upon the arm I by a lever-arm, N, which, embracing the arm I, is bolted at a to the yoke. The ring-coupling has on its forward under side a lug having a curved slot, 0, through which is passed a bolt secured to a lower extension of the yoke and to an extension of the leverarm N, by means of which the tilting of the finger-bar up and down is limited. While I prefer this construction, the curved slot and the bolt passing therethrough may be entirely dispensed with.

Upon the main frame is secured a notched sector-plate, O, to which is pivoted a hand lever, P, provided with the usual spring-bolt, adapted to engage one of the notches in the plate 0 to keep the lever in position. The lower extremity of this lever l is bent or curved backward, and is connected by a link, R, to the upper end of the arm N. Both the lower end of the lever and the upper portion of the arm have one or more perforations for attaching the ehds of the link for the purpose of effecting different adjustments, if desired. From this construction it will be seen that we obtain a direct draft upon the finger and cutter bars, which, while rigidly held in a constant draft-line,can yet follow the inequalities of the ground, forming what is known as a 95 perfect floating bar. Furthermore, in case of the finger-bar dropping into a hollow or dead furrow the fingers will not dig down, but, owing to the manner in which the bar is hung, and to the link R, which in such case 1o journaled the ratchet-sheave T, with the teeth of which the toe g of the pivoted gravitating dog U engages. This gravitating dog U is suitably pivoted to an ear of the bracket S, and has a rearward weighted extension, a forward lateral pedal, m, and an engaging-toe,

7 g, for the ratchet-sheave, and a second tripping-toe, with which the shoulder h of the lever A engages. Secured in the groove of this sheave is the rear end of a chain, V, which passes forward around a small guidesheave, b, journaled upon a bracket, 0, secured to the side of the tongue, and thence downward,where its forward end is connected to a projecting arm, d, upon the shoe G. Upon the ratchet-sheave spindle is secured one end of a spring, 6, whose opposite end is formed into a hook, which engages with a pin, f, projecting from the sheave, the purpose of which spring is to take up the slack in the lifting chain V, so as to keep the same taut when the cutter-bar is down, and to prevent loss of time and the repeated working of the lilting-lever, as would be necessary if there were slack in the chain. Between theratchetsheave and its bracket,and upon the extended hub of said ratchetsheave, is looselyjournaled the lift ng-lever A, whose lower end is constructed, as shown in Fig. 8, with the ratchetengaging shoulder g and tripping-shoulders h 1'.

step, it, upon the bracket, as seen in Fig. 6.

The bearing-aperture Z is elongated, so that.

when the lever is thrown forward'and the tripping-shoulder; bears upon the step it the lever is raised forward in such manner as to trip the locking-dog U, and at the same time lift the engaging-shoulder 9 clear above the ratchet to permit the finger-bar to fall and the chain to be unwound from the sheave, as will be readily understood. One of the teeth a of the ratchet is sufficiently enlarged to form a stop by comingin contact with the shoulder g of the lever A to limit the turning of the ratchet-sheave, and thereby limit the downward movement of the fingerbar. The locking-dog U has a lateral pedal, m, by means of which the driver can trip it with his foot without the aid of the hand-lever. Again, when it is not desirable to let the finger-bar fall suddenly the driver may press the dog out of engagement with his foot and retain his hold upon the hand-lever, thereby letting the bar down more than half-way before the lever would be automatically disengaged from the ratchet. Instead of letting the bar drop from this point, the dog may re-en- The shoulderh engages with the locking dog at j, and the shoulder i engages with a gage'with the ratchet, and the elongation in the lever-bearing would permit the lever to be thrown back clear of the ratchet to take a fresh hold, whereupon the dog could be again pressed out of engagement with the ratchet and the bar could be let entirely down by the hand-lever.

Referring to Fig. 5, it willbe seen that the application of the spring 6 is such that when the sheave is rotated to wind up the chain the pin f simply moves away from the spring when the spring reaches its point of equilibrium. At the same time the spring, when under pressurethat is, when the bar is downprevents any slack in the chain, for the reason before stated.

It is evident that instead of employing the elongated bearing in the lifting-lever to permit the disengagement of the engaging shoulder g from the ratchet, an ordinary gravitating or spring latch with a hand-hold, such as' employed upon the lever P, may be used.

In Fig. 4 the driving-gearing is fully shown.

Upon the axle, within the box of the main frame, is keyed or otherwise fastened the gearwheel B, which meshes with the pinion C, loosely mounted upon the countershatt. D, having eccentric journals held in hearings on the frame, which shalt also carries a gearwheel, E, integral with the pinion C, it desired. that meshes with a loose pinion, F, upon the axle B. Integral with this pinion F, and also loose upon the axle B, is a beveled gearwheel, G, which meshes with the beveled pinion H upon the crank-shaft 1, whose outer end is provided with a balance-wheel, J, having a wrist-pin to which the pitman K, which drives the cutter-bar, is attached. The essential feature of this gearing consists in the construction and arrangement of the eccentric counter-shaft shown in detail in Fig. 10, in connection with the locking crank-arm L, the construction of the counter-shaft being such that when it is oscillated downward and forward by throwing the crank L over backward to the position indicated by dotted lines in Fig. 4 it carries the gears C E forward into engagement with the gears B F, at which point the stop a, coming in contact with the frame or box of the machine, prevents any further oscillation of the eccentric shaft in that direction, and, as seen in Fig. 11, the direction of the revolution of the gears serves to hold them in constant engagement without the liability or the possibility of their accidental disengagement, and without the necessityot' any extraneous locking device, as will be readily understood. To unship the gears, it is merely necessary to raise and press forward the crank-arm L to the position shown in solid lines in Fig. 4, by
