' SPECIFICATION forming part of Letters Patent No, 361,607, dated April 19, 1887.

Application filed March 12, 1885.

Be it known that I, WILLIAM R. BAKER, a

citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Mowers, of which the following is a specification.

My invention relates to that class of mowers known as two-wheel hinge-bar front-cut 1nachines in which there is a floating and rocking finger-bar connected to the main frame by a coupling-frame and thrust-bar; and it consists in hinging the couplingarm and the thrust-bar to the main frame between the carrying-wheels upon diagonal pivots arranged upon the same axis with the rear pivot in close proximity to the axle; in combining with the coupling-arm and thrust-bar, both hinged upon a common diagonal axis, and with the finger-bar a tilting lever having its weightarm substantially in line with said axis, in order that the rising and falling of the fingerbar may not essentially affect the adjustment of the cutter-bar; in a hollow coupling-frame forked at its end to embrace the inner shoe of the finger-bar and having a recurved head on the rear arm of the fork and a vertical shielded gnideway in the front arm; in combining with the forked coupling-arm a thrust-bar pivoted to the main frame upon the same diagonal hinge with said coupling-frame and bolted rigidly to a seat upon the rear arm of the fork; in combining with a Wing or spur on the front arm of the forked coupling a lead-wheel receiving the point of said wing within its reenteringly-curved rim, to act as a rolling shoe or inside divider, and in various other details of stru cture,hereinafter described and claimed.

In the drawings, Figure 1 is a top plan view of a mower embodying my invention, the tongue and finger-bar being partly broken away. Fig. 2 is an elevation thereof from the divider side. Fig 2 is a detail showing the fore part of the coupling-fork and inner shoe and. the connection between the two. Fig. 3 is an enlarged detail in section of the leadwheel and the connection between it and the coupling-arm; Figs. 4 and 5, enlarged details showing the arrangement of the inner'shoe Serial No. 158,625. (No model.)

and rear arm of the forked coupling, and the lever and tilting chain with its bell-crank.

A represents the main or driving wheels of the machine; 13, the main frame with incased gearing; C, the drivers seat; D, the draft tongue, and E the cutter crank-shaft, the

arrangement of these being such as usual in mowers now in the market, and not requiring further description.

To the bracket 6, which shields the connection between the pitman and wrist-pin, and in front thereof, 1 hinge on a diagonal pivotpin, f, directed inward toward the axle and inner wheel,acoupling-arm, F, which may be of theusual form, but which, for lightness and increased strength, Iprefer to make as shown that is, it is cast hollow, in one piece of gradually-enlarging diameter toward the inner shoe, and near its free end is forked or provided with an offsetting arm, F, which extends rearwardly at right angles to the main arm ,for the purpose of supporting various parts, ashereinafter explained, until it reaches and passes slightly beyond the heel of the inner shoe, when it curves upon itself and terminates in a spherical head or ball, f, to form one member of a universal coupling with the inner shoe. Directly in front of this ball the extended main arm has a vertical recess or way, f formedin said arm. and in a downward offset from the same, and closed or shielded at top and'bottom, as well as at the sides.

A thrust-bar, G, is rigidly bolted to a seat formed upon the rear end of the arm F, and is hinged to the main frame just beneath the axle by a diagonal pivot, g, inline with or upon the same axis as the pin, by which the coupling-arm is hinged, the purpose of these diag onal pivots being to keep the finger-bar in line, notwithstanding its flexions, and also to more effectually resist the leverage of the finger-bar.

In front of the coupling-arm and integral therewith,or rigidly affixed thereto, is a wing, g, flaring outwardly and forwardly and termimating in a point or spur. A vertical slotted elongated boss, 9, upon this wing receives a bolt, securing thereto a tubular stub-axle, g supporting the lead-wheel H, which is thus made to carry the weight of the coupling-arm and parts which it supports, and which may be adjusted up and down along the slotted boss to change the height of the inner end of-the finger-bar. This lead-wheel is hollow, and is open on one side, except, as shown in Fig. 3, for a re-entrant rim, h,which forms an angular chamber, h,within the tread. ,Into this chamber the point or spur of the wing-piece projects, coming close to the edge of the rim and being entirely shielded thereby, so that the wheel and the wing-piece together form in effect both an inner divider and a rolling-shoe.

The inner shoe, I, has at its rear or at its wheel end a spherical socket, i, for the reception of the ball in the rear fork of the coupling-arm, and on its toe an anti-friction roller, i,which is received into and fits snugly within the shielded recess or Way in the front fork.

Behind this it is curved to substantially follow the. curved outline of the tread of the lead-wheel, and merges into the finger-bar K practically on a line with the inner face of said wheel.

To the inner or divider side of the rear fork of the couplingarm is pivoted a bell-crank lever, L, one arm, l,of which connects by ashort chain, 1, with the front part of the shoe, so as to lift it within its guideway, thus tilting the finger-bar,and yet permitting it to be further lifted by any sinuosity of the ground or by any obstruction. The other arm, 1*, of the bellcrank is connected by a link, Z, with a lever, M, pivoted at the rear of of the axle and having the usual segment-rack, m, and detent. The location of this lever is such as to bring its lower or Weight arm substantially in line with the diagonal axis of the coupling -arm and thrust-bar, so that the tilting adjustment of the finger-bar will be practically undisturbed by flexions or movements of the floating or coupling frame formed by the coupling-arm and thrust-bar. On the other side of the rear forkand beneath the thrust-bar is pivoted a gag-lever, N, the lower arm of which comes against a lateral spur, n, from the heel of the inner shoe, and the other arm has a socket, n, in which the thrust-bar'is received, and is connected by a chain, 'nflwith the liftingsegment 0 and actuating-lever O on the main frame, so that whenever this actuating-lever is moved to take in the chain the gag-lever will first act upon the finger-bar to lift its outer end, and will then, if the-movement of the lever is continued, catch upon the thrust-bar and lift the finger-bar and floating frame bodily.

In order to lighten the draft or pressure of the floating frame upon the ground, a stirrup, P, is hinged to the draft-tongue, and to this is attached the clip for the double-tree. A link, 19, connects this stirrup with the thrustbar about opposite the tread of the carryingwheel, so that as the stirrup is rocked by the draft of the team the link will draw upon the thrust-bar and tend to raise it and the parts to which it is rigidly attached, or which, by

means of the gag-lever, are so locked to the others as to be compelled to follow their movements.

I 'am aware that in Letters Patent granted.

to J. B. Kershaw, June 15, 1869, No. 91,347, a

peculiarly liable to catch and collect the fine gritty dust that is stirred up from the stalks and stubble in the passage of the machine, thus causing the joint to clog and grind, Wearing it out rapidly. In my machine, on the contrary, the socket, being upon the heel of the shoe, has its mouth directed, to the rear, and thus serves the twofold function of member of the joint and shield therefor.
