SPECIFICATION forming part of Letters Patent No. 470,331, dated March 8,1892.

Application led September 5, 1891. Serial No. 404.806. (No model.)

To aZZ whom it mag/concern.-

Be it known that I, JOEL FARRINGTON, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in Blowing-Machines; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the artto which it appertains to make and use the same.

This invention relates to mowing-machines; and it consists in certain improvements in the means for raising and lowering the fingerbar, as will be hereinafter fully explained, and pointed out in the claims.

Reference is had to the invention shown in Letters Patent of the United States granted to me January 7, 1873, No. 134,531, on which my present invention is an improvement.

In the accompanying drawings, Figure l is atop plan view of a mowing-machine containing my present improvements. Fig.2 is a side elevation of the same machine looking from the end of the cutter-bar. Fig. 3 is a perspective view of the lifting-lever G G detached from the machine; and Fig.4 is a perspective view of the lower end of the coupling-arm E, the inner end of the linger-bar F, and the gag-lever G2.

Letters of reference in all the figures indicate parts as follows:

A is the main axle; B B, the driving-wheels; O, the frame and gearing-box; O', the crankshaft sleeve or housing; O2, the crank; C3, the connecting-rod or pitman; K, the knives; K', the knife-bar; K2, the wrist on the knife-bar to which the pitman connects; F, the iingerbar; E, the coupling-arm; f, the joint or hinge of the finger-bar to the coupling-arm; D, the tongue-plate; D', the tongue; H, alifting arm or horn connected with the frame-work C C at c by bolts h; G G', the lifting-lever; G2, the gag or lock lever; g, the fulcrum of the lever G G g', a lifting bar or link connecting the prong G of the lever G G with the lifting-arm Il; g2, the fulcrum of the gag-lever; g3, the chain connecting the lever G with the gag-lever; J, a hand grip-lever on the lever G G J', a pawl operated by the handgrip J; J2, a notched quadrant with which the pawl J engages.

Other letters of reference will be referred to in place herein.

As the invention relates wholly to the means for lifting the finger-bar and said means are applicable to machines of various construction as to other parts, it is not necessary to further describe the general construction of the machine than to point out the associated parts, as above. The lifting-lever G G straddies the tongue D and is pivot-ed at g on a bolt or pin,which passes through the tongueplate D. The ordinary grip-lever J, pawlJ, and notched quadrant J2 are used to hold the lever G G in any desired position. The prong G of the lifting-lever is shorter than the main part G, and both are curved upwardly at their ends. The prong G is connected with thelifting-arm H by a lifting bar or link g', which stands parallel with the vertical part of the arm I-I and is pivoted to said arm at its upper end and to the lever at its lower end. The arm Il is attached to the sleeve C at c by bolts 7L, and it is guided in a block d on the side of the tongue lD by a lip h thereon entering a notch in said block, as clearly seen in Fig. l. The main arm G of the lever connects with the gag or lock lever by a chain g2, as in the former patent referred to. The gag-lever G2, as here shown, is longer than in said former device and is of different form, and it has the same spur or lug e at its outer end for engaging the coupling-bar E 5 but here I further add a lug e dn the coupling-bar, which extends out over the gag-lever G2 back of its pintle g2. This lug e supplements the spur e in supporting the strain upon the lever G2 when the linger-bar is supported in an elevated position. p

The form of the lever G G here shown, the manner of pivoting the same, and the introduction of the lifting bar or link g', together with the form of the lifting-arm I-I and the manner in which it is guided or supported; add greatly to the efficiency of the lifting devices and constitute a very important improvement upon the construction heretofore used by me. For instance, in my former construction that part of the lifting-lever which engaged the lifting -bar (said parts being marked g, g', f, and f in said patent) was not integral with the lever G, but was in the form IOO of a crank-bar connecting With the lever G s0 as to be turned by it and serving as apivot for the said main lever G. My present construction is much stronger and the prong G can be made longer, and by substituting the lifting bar or link g' for the pin .and slotted eye used as a means forconnecting thecrankarm g' With the extension f' from the bar f in said forlner construction Iain able, through the long curved-up lever-prong G' and the link g', to obtain a toggle action in place of a friction-generating sliding connection and also to apply the power necessary for lifting the parts at the most advantageous point; but a more important point gained is that I am ableby this newconstruction to get more throw, and hence can lift the finger-bar much higher than I could with the old form. This is of great advantage in crossing ditches or passing over rocks, stumps, or mounds. I have found by actual experience thatin the present form I can raise the linger-bar higher-and with less exertion than with the old construction.

Vhat I claiin as new is*- 1. In a mowing-machine, the combination, substantially as shown, of the forked liftinglever G G', pivoted on the bolt g, the liftingvarm H, attached to the sleeve C', and the lifting-link g', pivoted at its lower end to the lifting-lever and at its upper end to the liftlng-arm.

2. In a mowing-machine, the combination, substantially as shown, of the forked liftinglever G G', pivoted astraddle of the tongue, the lifting-arm H, extending from the sleeve C' and guided in a block on the tongue D', and the lifting-bar g', pivoted at its lower end to the lever-prong G' and at its upper end to the lifting-arm II.

3. In a mowing-machine, the combination, substantially as set forth, of the forked liftin g-lever G G', pivoted astraddle of the tongue D', the lifting-arm I-I, extending from the sleeve C', the lifting-link g', connecting the upper end of the arrn I'I With the prong G' of the lever, the gag-lever G2, connected with the prong G of the lever, and the lugeon the coupling-bar E, engaging said lever G2 back of its pintle g2.

In testimony whereof I afx my signature in presence of two Witnesses.

JOEL FARRINGTON.
