MOWlNG-MACHINE.
SPECIFICATION forming part Of Letters Patent No. 653,419, dated July 10, 1900.
Application filed December 1], 1399. Serial No. 739,901. (No model.)
To all whom it mag concern: I
Be it known that I, MAURI E KANE, a citizen of the United States, residing at Austin, in the county of Cook and State of Illinois, have invented a new and useful Mowing- Machine, of which the following is a specification.
This invention relates to mowing-machines.
The object of the invention is to provide means for restoring and maintaining alinement between the cutter-bar and its actuating-pitman.
The invention consists, substantially, in the construction, combination, location, and re1ative arrangement of parts, all as will be more fully hereinafter set forth, shown in the accompanying drawings, and finally pointed out in the appended claims.
Referring to the accompanying drawings and to the various views and reference-signs appearing thereon, Figure l is a view in plan of a mowing-machine, showing the application thereto of a construction embodying the principles of my invention. Fig. 2 is a detached detail view, in side elevation, of the yoke upon which the cutter-bar is supported and showing a construction embodying my invention, the finger-bar being in transverse section. Fig. 3 is a plan view of the construction-shown in Fig. 2, the cutter-bar be ing broken off. Fig. 4 is a broken detached detail view of the eyebolt for restoring the alinement of the cutter-bar with its actuatingpitman.
The same part is designated by the same reference-sign wherever it occurs.
In the efficient operation of mowing-machines it is desirable and important to maintain accurate alinement betweenthe cutterbar and its actuating-pitman. In use through the wear of joints and parts which support the inner end of the finger-bar and the backward pressure exerted upon the finger-bar as the machine advances over the ground and encounters the grass to be cut or other obstruction a tendency is quickly developed in' the finger-bar to sag backward, and it is evident that only a slight wear of the joints at the inner end of the finger-bar will result in a magnified degree of backward sagging at the outer end of such bar, as clearly indicated in dotted lines in Fig. 1. This backward sagging of the finger-bar is objectionable and undesirable for the reason that thereby the path of reciprocation of the cutter-bar becomes deflected or changed out of accurate alinement with the pitman through which re ciprocations are imparted to the cutter-bar, andas a rapid reciprocation is imparted to the cutter-bar while the machine is in use such deflection of the path of reciprocation of the cutter from true and accurate alinement with the line of movement of the pitman through which the cutter bar is reciprocated (and which is not affected by the rearward pressure upon the finger-bar or by wear in the parts which support the finger-bar) develops friction and rapid wear and looseness of the cutter-bar, thus not only causing the machine to run heavy, but rapidly wearing out the parts. Various expedients have been resorted to with a view to overcoming this difficulty, and in my priorapplication,Serial No. 679,712, filed May 12, 1898, I have shown, described,
and claimed a construction for restoring and maintaining alinement between the cutterbar and its actuating-pitman by relatively adjusting the yoke upon which is hinged the shoe which supports the cutter-bar, such relative adjustment being effected with respect to the coupling-arm upon which the yoke is mounted. The present invention relates to means for securing the same object and embodies a modified construction wherein the cutter-bar is adjusted relative to its supporting-shoe and without disturbing or affecting the position or adjustment of the yoke.
Referring to the accompanying drawings, reference-sign A desigifates a mowing-machine, which may be of the usual or any ordinary or well-known type of construction or arrangement. B designates the coupling-arm; O,the-yoke,which is supported or sleeved upon the end of the coupling-arm; D, the shoe, which may be hinged or otherwise supported upon the yoke 0 in the ordinary or any suitable manner, whereby the finger-bar supported thereby may be folded into convenient position for transportation, and E is the fingerbar, adapted to receivethe cutter-'barF in the These parts so far mentioned may be of the usual or any wellknown or suitable construction.
In my prior application I have provided means for restoring the alinement of the cutter-bar with respect to its operating-pitman G by adjusting the position of the yoke O with respect to the coupling-arm 13, upon which said yoke is mounted, such adjustment of the yoke effecting the restoration of alinement between the cutter-bar and its operatin g-pitman byreason of the fact that said cutter-bar reciproc'ates in guides formed in the finger-bar and the latter being supported upon the shoe, which is in turn supported upon or= hinged to the yoke. In the present application Tpropose to secure the same results by adjustin g the finger-bar with respect to the shoe. To this end I secure the innerend of the finger-bar to the shoe by means of two bolts, one bolt H passing through said bar and shoe and the other bolt J also passing through said bar and shoe, but the slot K, (indicated in dotted lines in Fig. 2,) through which said bolt passes, being elongated, so as to permit lateral movement of said boltin said slot, the bolt J being located nearer the inner end of the bar E than bolt H, as clearly shown, said bolts H and J being provided with nuts L and M, respectively, by which said bolts may be clamped up to lock the finger-bar and shoe in the positions to which they may be adjusted. Arranged to pass through theuptnrned heel or lug N on the shoe D is an eyebolt P, having a threaded stem, as clearly shown, and the bolt J is arranged to pass through the eye R of said eyebolt, as clearly shown in Figs. 2, 3, and 4. Set-nuts Q are threaded upon the stem of eyebolt P and are arranged, respectively, on opposite sides of the upturned heel or lug N. By this construction it will be seen that by backing off one of the nuts Q and turning up on the other, after loosening the nuts L M of bolts H and J, the finger-bar E will be adjusted with reference to its supportingshoe, said finger-bar swinging about bolt H as a pivot, the elongated slot K in the shoe permitting such swing. In this mannerl secure a ready and easy restoration of alinement between the cutter-bar and its actuatin g-pitman to correct and compensate for any backward sag in a very simple and expeditious manner by merely swinging the fingerbar which supports the cutter-bar in the manner above described. It will be observed that only a slight adjustment or swing of the inner end of the bar is all that is required, as the movement at such inner end will be m ultiplied at the outer end of such bar.
Having now set forth the object and nature of my invention and a construction embodying the principles thereof, what I claim as new and useful and of my own invention, and de' carried, a shoe upon which said finger-bar is supported, said shoe being pivotally mounted, whereby the finger-bar may be folded into convenient position for transportation, an actuating-pitm an for said cutter-bar, of means for adjusting the position of the finger-bar upon and with reference to said shoe; whereby alinement between said bar and its actuating-pitman is restored and maintained, as and for the purpose set forth.
2. In a mowing-machine, a finger-bar, in which the cutter-bar is carried, a shoe for supporting the same,and an actuating-pitman for the cutter-bar, in combination with means for swinging the cutter-bar forwardly upon and with reference to said shoe, to restore and maintain alinement between said cutter-bar and pitman, as and for the purpose set forth.
3. In am owing-maohine,a fi nger-bar adapted to carry a cutter-bar, a pitman for actuating said cutter-bar, and a shoe fox-supporting the finger-bar, in combination with means for adjusting the finger-bar upon and with reference to said shoe, whereby the outer end of said finger-bar may be moved forwardly to restore and maintain alinement between said cutter-bar and its actuating-pitman, as and for the purpose set forth.
4. In a mowing-machine,a finger-bar adapted to carrya cutter-bar, an actuating-pitman forthe latter, a shoe, the finger-bar being pivotally supported thereon, said shoe provided with a laterally-extending elongated slot, a bolt passing through such slot and securing the finger-barto the shoe, in combination with an eyebolt engaging the first-mentioned bolt, and means for adjusting such eyebolt; whereby said fingor-bar is capable of being rocked about its pivot, to restore and maintain alinement between said bar and pitman, as and for the purpose set forth.
5. In a mowing-machine, a finger-bar, a cut-- ter-bar supported thereby, an actuating-pitman for said cutter-bar, a supporting-shoe for said finger-bar, said shoe provided with an upturned heel or lug and an elongated slot, a securing-bolt for said finger-barand shoe, an adj usting-bolt for said fin ger-bar and shoe, said adjusting-bolt arranged to pass through the elongated slot in said shoe, an eyebolt arranged to be engaged by said adjusting-bolt, and having its stem arranged to pass through said upturned heel orlug, and set-nuts mounted upon said eyebolt-stein and arranged on opposite sides, respectively, of said upturned heel or lug, whereby said finger-bar may be rocked or swung upon said shoe to restore and maintain alinement between said cutter-bar and pitman, as and for the purpose set forth.
In witness whereof I have hereunto set my hand, this 8th day of December, 1899, in the presence of the subscribing witnesses.
