Be it known that I, CHARLES S. SHARP, of

Auburn, in the county of Oayugaand State'of New-York, have invented a certain new and useful Mowing-Machine, of which the following is a speciiication. f

My invention has for its lobject the production of particularly simple, economical, and efficient connections between the lnger-bar and coupling-frame of a mower; and it consists in the combination, construction, and arrangement of the component parts of the contiguous portions of said finger-bar and frame and the connections between the same, as hereinafter fully described, and pointed out in the claim.

In describing this invention reference is had to the accompanying drawings, forming part of this specification, in which like letters indicate corresponding parts in all the views.

Figure 1 is a top plan of a mowing-machine embodying my invention, a portion of the pole being broken away. Fig. 2 is an enlarged top plan of contiguous portions of the finger-bar and the coupling-frame opera-. tively connected together. Fig. 3 is avertical sectional view taken on line 3 3, Fig. 1. Fig. 4 is a horizontal sectional view of the front connection between the finger-bar and the coupling-frame. Fig. 5 is a rear elevation of the detached inner shoe for the fingerbar and the adjusting member journaled in said shoe. Fig. 6 is a horizontal sectional view taken on line 6 6, Fig. 5. Fig. 7 is an enlarged plan view, partly'in section, of a portion of the parts seen in Fig. 2. i

A and B represent, respectively, the {ingerbar and the coupling-frame of my mowingmachine, both of which parts may be of any suitable form, size, and construction. Said tinger-bar A and coupling-frame B are provided, respectively, with aninner shoe a and ayoke b, which, so far as this invention is concerned, form, essentially, parts of theiinger-bar and the coupling-frame. The yoke is provided with a socket b', extending from the rear forwardly and having lsubstantially vertical side walls b2 bias best shown in Figs. 2 and 3, and a seating. 61,979. @modela L diagonalpush-barts, forming part ofthe A'couplingframe Bhas afforward-extension 64,

projecting.intothe socket- The extension of Athepush-baris provided withan eye, through which theend ofthe frame-bar b5 extends, The yoke .b .is journaled upon the bar 65,.-and the extension b4 of the -bar 3 cooperates with the vertical walls b2 on its opposite sides and limits the endwise movement of the yoke on the frame-bar b5. p

The finger-bar A, or, more strictly speaking, its inner shoe a, is provided with separated relatively fixed attaching parts or ears a' a2, which rise upwardly from the contiguous portions Yof said finger-har, are arranged one in advance of the other, and are connected independently to the coupling-frame B, and preferably to attaching parts or ears t 67, depending from the yoke t, and also arranged one in advance-of the other.

v The'parts or ears a b are connected by a substantially horizontal pivot e, Fig. A, which Vhas a limited play in a slot in the ear b, and the contiguous surfaces of said parts or ears a be are formed concavo-conveX, so that tlie surface of the part or ear a' adjacent to the part or ear b is free to move relatively to said part or ear b as the outer end of the fingerbar is forced forwardly or backwardly.

The parts or ears co2 67 are connected by an adjusting member o" and a substantially horizontal pivot o?, Figs. 6 and 7, the adjusting member c being journaled in the part or ear a2 and provided with an eccentrically-arranged opening and the pivot 02 being passed through the part or ear 67 and through the eccentrically-arranged opening in the adjusting member 0 and alined with the pivot c transversely to the length of the finger-bar A. Said adjusting member c may be held in position by any suitable means, as a bolt 03, engaged with' partly rotated in the attaching part or ear a2, thus moving said part or ear laterally relatively to the other part or ear a without varying the alinement of the pivots c c2. During the adjustment of the linger-bar by the member c" the part or ear a is free to move relatively to the part or ear b to a limited extent for permitting the desired movement of the part or ear a2. After the desired adjustment of the outer end of the finger-bar the bolt 03 is tightened, whereupon said finger-bar is held in its adjusted position. When adjusting the linger-bar, it is usually unnecessary to adjust the bolt c; but it will be understood that said bolt may be adjusted, if desired.

The construction and operation of my mowing-machine will now be readily understood upon reference to the foregoing description andv the accompanying drawings, and it will be particularly noted that more or less change may be made in the component parts thereof Without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a mowing-machine, the combination of a coupling-frame bar, a yoke mounted on the coupling-frame bar and provided with a socket extending forwardly from a rear face thereof, and a diagonal push-bar formed with a forward extension projecting into the socket and connected to the coupling-frame bar, said extension eoperating with the side walls of the socket to limit the endwise movement of the yoke on the coupling-frame bar, substantially as and for the purpose described.

In testimony whereof I have hereunto signed my name, in the presence of two attesting witnesses, at Auburn, in the county or' Cayuga, in the State of New York, this 10th day of May, 1901.

CHARLES S. SHARP.
