MOWER.

SPECIFICATION forming part of Letters Patent No. 572,549, dated December 8, 1896. Application filed April 1, 1895. Serial No. 544,063. (No model.)

To all whom it may concern:

Be it known that I, SAMUEL V. KENNEDY, of St. Paul, Ramsey county, Minnesota, have invented certain Improvements in Mowers, of which the following is a specification.

My invention relates to improvements in mowing-machines, its object being to furnish a pivotal support for the fin ger-bar at the rear of and near its horizontal plane, so as to prevent any forward movement of the bar when tilted and also to furnish substantial support and connection at a point forward and above the pivot, so as to prevent lateral movement ofthe connected parts, whereby the bar would be thrown out of alinement, together with means for lateral adjustment on this support, so as to secure and maintain perfect alinement of the finger-bar and pitman.

To this end my invention consists in providin g an arched or bifurcated hanger, which is pivotally connected by its rear leg to a depending lug carried by the main frame, which frame is preferably made of a single casting. The legs of the hanger are also provided with hinge members, to which is connected the finger-bar, so that the finger-bar stands forward of and a little below the hanger-pivot.

The hanger is further supported at the top from the main frame by means of a stud-and slot c0nnection,which permits a limited movement of the hanger in a vertical plane upon its pivot and also permits of lateral adjustment upon said stud, whereby the connected finger-bar may be adjusted and held in alin ement with the pitman.

Other features of construction will appear more fully in the following more specific description and claims.

'In the accompanying drawings, forming part of this specification, Figure 1 is a side elevation of a mower embodying my improvements, the right-hand driving-wheel being removed to disclose the construction. Fig. 2 is a partial side elevation looking toward the opposite drive-wheel. Fig. 3 is a detail plan view of the main frame with the attached finger-bar, shoe, and grass-guard. Fig. 1 is a detail plan view of the finger-bar and connected shoe. Fig. 5 is a detail illustrating the stud-and-slot connection between the hanger and frame, and Figs. 6 and 7 are other details.

In the drawings, A represents the main frame of the mower, consisting of a single casting. The cylindrical member 2 serves as a sleeve for the axle 3 and is provided with rearwardly-exten ding arms 4 and 5 to furnish journal-support for the driving-gear. The left-hand member 6, at right angles with the member 2, is a crank-shaft sleeve. The righthand member 7, also at right angles with the sleeve 2, but inclined downward slightly more than the member 6, serves as a connection and support for the finger-bar, and the V-shaped double brace 8, with its apex connected to the axle-sleeve and its legs to the ends of the members (5 and 7, strengthens and renders the frame rigid.

B is an arched hanger, the roar leg 9 of which is supported upon the pivot 10, connected to the lug 11, depending from the frame member 7. This hanger is also provided with a transverse slot 12, which has the curvature of a circle with the pivot 10 for its center. The face of the hanger is provided with the groove 13 parallel with, but wider than, the slot 12 for the purpose hereinafter described. The st ud-bolt 14, passing through and secured to the frame member 7, carries a sleeve 15, which fits snugly in the slot 12 and has a flange 16 on its outer end bearing against the shoulders 17, formed by the bottom of the groove 13, thus holding the hanger The lateral position of the hanger may be adjusted by means of washers 18, interposed between it and the frame, whereby'the fingerbar may be set and held in alinement with the pitman. Arranged upon the other end of the bolt 14 and between its nut 19 and the frame member I provide a washer 20, having an eye 21, to which is attached the clevis 22, v

carried by the lifting-chain 23.

The legs of the hanger B carry journals 24,

and to receive the gudgeons 26 and 27, furnishing a hinge-support for the finger-bar shoe 0. Connected at one end to the gudgeon 27 is the grass-guard 28, which extends in front of the frame and has its other end formed with a reverse bend 29, entering a socket 30, in which is arranged a spring 31, adapted to bear upon the end of the rod to prevent its rattling in the socket. is the lifting-lever, carrying the quadrant 33, to which the chain 23 is attached.

34 is the draft-rod, connected at its rear end to the upwardly-projecting lug 35 upon the frame and running through a link or eye 36, supported upon the pole 37.

Thehanger B is provided with an eye 38 at its top, to which is connected the rod 39, running to the lever 40, pivoted to the frame of the machine, the angular position of which is adjustable upon the quadrant 41 to determine the height or position of the hanger. By throwing the lever backward the hanger is lifted, turning on its pivot 10, so as to tilt the points of the guards-upward, but without any appreciable forward movement of the fingerbar.

The rear end of the adjustable sole-plate or heel 42 upon the shoe 0 is at the same distancefrom the points of the guards as the rear end or heel of the dividenshoe upon the outer end of the finger-bar. Consequently the points of the guards are all tilted to uniform height. The shoe C is provided with the usual fender-rod 44 and has also a rearwardly and laterally extending arm 45, the top "of the end of which is normally in line with the pivot of the hanger.

To the lug 46, depending from the frame of the machine, is pivoted the gag-lever 4:7,which extends back over the arm 45 and stands normally slightly above it.. The lever is conn eeted by the link 48 with the crank 4:9,which is pivoted to the pole-casting 50. The crankarm 51, rigidly connected to the crank 49, is connected by the rod or link 52 to the lever The crank is also provided with a socket 53, into which is fitted the treadle-lever 54. It will thus be seen that with the depressing of the treadle-lever the gag-lever 47 is operated to bear upon the arm 45 and turn the finger-bar shoe upon its hinge, so as to throw the outer end of the finger-bar upward. At the same time, through the crank-arm 51 and rod 52, the lever 32 is operated to lift the forward part of the frame and connected parts around the axle 3 as a center, and conversely the operating of the lever 32 serves to actuate the gag-lever. The initial movement of both serves to first lift the frame and fingerbarinto engagement with the gag-lever, so that the outer end of the finger-bar is not allowed to drop, and as the movement continues it is raised more rapidly and higher than the frame. By supporting the fingerbar shoe upon the arched hanger, pivoted, as described, at its rear and in nearly thesame horizontal plane as the finger-bar, in the tilting of the finger-bar the alinement between the pitman and the sickle-bar (not shown) is practically ll11Va1i6(i,-\Vi1iCl1 is of. great practical value in the operation of the machine.

I claim 1. In a mowing-machine, the combination with-the finger-bar shoe and the main frame having a pivot-stud adjacent the shoe, of the hanger hinged to said shoe and mounted on said pivot, the stud-and-slot connection between said hanger and frame, whereby the rotary movement of the hanger on its pivot is limited, and means for longitudinally adjusting the position of the stud in said slot, so as to aline the finger-bar.
