Be it known that I, JAMES MACPHAIL, a

V citizen of the United statesyresiding at Blue Island, in the county of ,Qook and State of Illinois, have invefitedjcertain new and useful Improvements inflMoive fs, of which the following-is aspecificatiomf. 1

Y a 'The object of my invention is to make the finger-bar raising and loweringdevices oper ative'by hand or foot, and operatingindepende v ently of or simultaneously with each other;

my invention; Fig; 2*is a. Section on the line and my invention consists of vcertain'neiir and specifically pointed-outin the claim. v

- Referring tothe accompanying drawings, which form a part of this specification, Figure 1 is a plan View of a" mower embodying 2 2'in Fig. 1. 1- Fig. 3 is a like section showing the foot lifting-.lever-of. the machine depressed. Fig. 4 is a detail sectionon the line 4 .4 in Fig. '1. Fig. 51m section on the same line as the last, showing; the finger-bar and shoe of the machine tilted. Fig. 6 is a side elevation of a finger-'bar-liftingdevice. Fig.

7 7 is a detail elevation showing arack and the spindle-bearing of the finge'r-bar-lifting device. Fig.8 is a side elevation of, the'ma chine, showing the hand andfoot lifting thereby.

{A A Adam respectively the axle, wheels, and main framejof the-mower.

1 B is a rack mounted on the main frame A of the machineand having a spindle 13' projectingtherefroin and detent-notches B therein. p

C is a finger-bar-lifting device provided I with an upwardly and forwardly projecting arm C, a downwardly and backwardly pro jecting arm C and mounted 011 the spindle B, so thatit may be freely oscillated thereon.

D is the inner shoeof the mower.

D is a yoke jointed by pivots-D D to upwardly-projecting lugs I) D' on the shocl).

D is a tilting-post rigidly connected .with

the upper portion of the yoke D.

E is a coupling-bar having a universal connection by one end at E with the main frame the machine.

K is an auxiliary spriug extendlng from A and being fastened by means of bolts E at the other end to the yoke D.

- F is a push-bar pivoted by one end to the tilting post D at F and by the other-end at F to the rigid downwardly-projecting lug A I on themain frame A The coupling-bar E, yoke D, and push-bar F constitute what is commonly known as the floating frame of a mower.

G is a foot liftinglever pivotally connected. at G with the free end portionof the arm (L of the finger-bar-lifting deviceG and adapted t'ofoperate therethrough to raise tlieffloating fraine'of the machine.

' G"'is a 'setrscr'ew for adjusting the elevation ofthe foot-lever G. a p H is a, draftrod bracket secu red to the pushbarF.

H is a link or any other suitable on'nction through the gag-lever 11 between the ing device G and the floating frame oft-he machine. J v

I is a hand liftingdever rigidly connected with the finger-bar-lifting device 0 and mounted on the spindle B',\vl1ich passes through a circular opening (not shown) in thelower end thereof.

v I is a detent adapted to engagewith any of p the notches B in the rack B. levers depressed*and the finger-bar elevated I isa hand-latch pivoted to the upper endv of the hand lifting-lever I. l

. I is a rod connecting the detent I with the hand-latch I J is a clevis suspended from thejmachinetongue J by means of a pivot-joint J so as to freely swing thereon.

J 3 are jaws integral with the clevis J and carry an evener J which is jointed thereto by means of a bolt J J is a draft-rod connecting the clevis J, through the bracket II, with the push-bar F.

K is a bracket secured to the tongue J of the free end portion of the arm'C of the lifting devicc C to the bracket-Kon the ton guc J.

M is a main sprocket-wheel.

O.is a bracket bolted to the main frame A3,-

free end of the arm 0 of the finger-bar-lifthaving a crank-shaft box 0', extending lon'gitudinallytherethrough, provided with a recessed circular shield O'-,' having an axle O projecting at right angles to crank-shaft box from the inside of the center of said shield. The parts 0, O, 0 and O are formed by casting them in a single piece.

P is a crank-shaft provided with a crankwheel P, having a wrist-pin P projecting therefrom and mounted in the crank-shaft Q is a sprocket mounted on. the axle 0 R is a drive-chain connecting the main downward to the posit-ion shown in Fig. 8,

when the detent I, Fig. 5, ,will engage with the lowest notch 13 Fig. 3, in the rack B. Obviously the levers G I may be used conjointly and simultaneously or separately, according as may be most desirable or advantageous to the operator.

I do not desire to claim herein the invention shown by combining the main frame A and bracket 0, cast in one piece and bolted to the frame A 'The invention shown thereby is the subject-matter of a separate application, having Serial No. 602,105, filed August 7, 1896, and it has been hereinbefore described for the purpose of showing its operation in connection and combination with other devices to form a complete mower.

I claim In a front-cut mower, in combination, the

main axle, the main frame'mounted thereon, a rack mounted on the main frame and hav:.

ing a spindle projecting therefrom, the finger-bar-lifting device provided with an upwardly and forwardly projecting arm 0' and a downwardly and backwardly projecting arm C and mounted on said spindle, the floati-ng frame of the machine, a connection between the free end of the arm G and the floating frame of the machine, and a foot liftinglever pivdta'liy connected with the free end portion of the arm C of .the fin ger-bar-li'fting 'device and adapted to operate therethrough to raisethe floating frame and having its elevation adjustable by means of a set-screw, substantially as and for the purposespecified.
