IMPROVEMENT IN MowlNG-MAcl-i'mes.

Speoilication forming` part of Letters Patent No. 156,760, dated 'Novemberl 10,1874; reissue No. 7,540, dated February 27,1877; application tiled January 1B, .1877.

Stute ol" New York, have invented certain new and usel'ul lmprowments in Harvesting-Machines, of which the following is a specilication My invention rel-.ttes to the well-known clnss of twowvheeled front-cut hinge-bar mowA ing-ninchinr-rs haring rocking folding' tingelhealns--snch, lor instance, as that shown in Letters Patent ot' the United States No.5l,546, granted to me December 19, 1865.

The object ol" the first part of my invention is to regulate the rocking or rolling' Vof the 'linger-hewn upon its longitudinal axis; to which end this part ot' my invention consists of a ianple device, hy which the linger har, or the points ot' the guards, may he turned up and maintained in such position as that,` in passy ing;- stones', hnmmocks, or other obstructions, the cuttingapparatus will glide over them uninjured without attention on the part of the operator, while at the sume time leaving the cutting apparatus free to move in any direction required under the usual working comlitions, thus constituting a valuable improvenient lor use upon rough land.

My invention further consists of an improvenn-.nt in thel track-clearer, by which its dividing, stick or finger may he rolled in its shoe, so as to raise or lower its` outer end at will, to adapt it to dil'erent conditions of the crop.

The subjectmatter claimed will hereinafter specilically he designated.

The accompanying drawings represent so much of a mowingnnachine embracing my improvements as is necessary to illustrate the subject-matter herein claimed.

Figure 1 represents a view in perspective ther-col', with the inner driving-wheel removed to show the parts which would otherwise. he concealed by it. Fig. 2 represents a View in elevation of the machine, as seen from the di- Vider side, with the inner driving-\vheel removed, and withthe cutting apparatus in section on the line l. 1 of Figs. land 3. Fig. 3 rcpl i resents a plan or top View ofthe ilexihleconncctions between the main frame and cutting apparatus. Fi". 4 represents a View in. eleva-v tion of portion's ot' the flexible-connections, partly in section on the lille 2 2 of Figs. 1 and 3, showingr particularly the details ot' the gagiron or locking-stop. Fig. 5 represents a plan view of the divider end ot' the cutting apparatas; and Fig'. 6 a side elevation thereof.

Two main driving and supporting;- wheels, A A', are lnounted upon an. axle, B, in wellknown ways, the axle revolving in boxes in a cast-metal main t'ranie,.G, havingl a drooping rear end. A bar or standard, d, inclined hackward and upward from this frame supports a seat, D, for the driver behind the axle. This standard passes through an upper platform or supplementary frame,- G, mounted upon the lew'x frame U, partakingof its movement. A coupli|ig-arm,.fE, is hinged at its upper Aend to arockinghearing, e, in the outer front corner ofthe frame. in which hearing the coupling, arm Lswivels. The lower end of the couplingarm is hinged to the shoe, as usual. A thrusthar, F, is pivoted in rear to the main traine, while its front end is pivoted yon aluggf, ou the coupling-arm. A wedge-shaped block, E', is lilxed upon, and extends bucket', the coup ling-arm, and is acted upon by a rocking cam or wiper, G, rocking upon a pivot, g, on the thrust-bar, and connected, by means ol" a link, h, with a hand lever, H, pivoted upon the frame within convenient reach ot' the driver, and provided with the usual spring-latch and detent, by which means the coupling-arm maybe rockedV or rolled on its longitudinal axis by the attendant while in his seat.

'lhe guards may thus he held at any'desired elevation, while their points arel free to rise above that point, land, by moving:r the handlever backward, the downward range of inotion ol` the guard-lingers will be increased; though, under all circumstances, thc rocking cam will act as a stop, to prevent to'o great 'downward detlection ot' the points ol' the guards.

A lifting lever, M, pivotcd upon the main frame, provided with the usual detent or hohling pawl, is connected hy its liftingchain N witha crank-arm or gag-nomi), rocking in bearings underneath thc coupling-arm and provided with a. projecting locking-toe, O',

l, which comes between the couiiliug-a'rrn and` the heelot' A'the shoe, as vshown in Fig. 4,'by which mode of construction, when the cutting apparatus is lifted,-the heel of the shoe abuts against this locking-stop and causes the fingerbar to lift horizontally Withoutexing its joint, as'it would otherwise do, 'while at the same time leaving it 4free to rock and roll or be tilted by the tilting-lever and rocking-cam, as

above described.

1t will be observed that by my improvement the lifting` mechanism is entirely independent di' the tilting mechanism, so that I ain enabled to rock theeutter-.bar either while resting` upon v tlie ground or while suspended by the liftingchain.

ik linger-beam, I, is attached to the inner shoe in the ordinary manner, kand carries a dividler, J, at its outer end, to which a dividerirou, K, is secured, and to which a trackclearer or divider-hoard, K', is pivoted, as

usual. A socket, k, on the upper end of the divider-iron, receives the rounded end oi' the dividing' stick or finger L, which, in combination ivi h the track-board K', makes the track- 'cleareig and throws the cut grass away from that which is left standing. The socket k is provided with a slot, l, in which a screwbolt, l', inserted in the divider-stick,l works. kThe moving ofl this bolt in its slot allows the di-r vider-finger to be adjusted .at will, as shown by'dotted lines in Fig. 6.- The rear-end of the divider-stick is bent 'or curved, as shown in Fig. 5. In lodged grass or grain this point, which is ordinarily horizontal, is turned down1 allowing the `tangled mass of cut grain or grass to slip 'oi the stickleaving the cut stalks evenlyscattered over the groundand 'not running them together in heaps, which is done when' the stick is high and unadjustable. rIn cutting;` tall standing crops the point of the ,divider-stick is turned up, keeping the Y stalks erect and not allowing. the cut to become 'entangled with the uncut stalks, thus making an easily adjusted and efficient trackclearer. What I claim as myinvention, and desire to secure by Letters Patent, is-

1. The combination, substantially as herein before set forth, of a main frame, a rockinghiuged coupling-arm, a thrust-barconnectng the main frame and coupling-arm, a lifting apparatus, a-tilting lever, a rocking-cam, and' a wedge `upon the coupling-arm. Y Y 2. The combination, `substantially as hereinbeforef set forth, of the wedge-block on the rockingcoupling-arm with the yrocking-cam 0u the thrust-bar, for tilting or rocking the fingerbar on its longitudinal axis.

3. The combination, substantially as hereinbefore set forth, of the main frame, the rocking; coupling-arm, the block or wedge thereon, the push-bar connecting the main frame and coupling-arm, the baud-lever, its link, and the rocking-cam on the thrust-bar.

4. rlhe combination ofthe rocking couplingarm, the shoe, the cranked gag-iron or lockingstop, rocking underneath the coupling-arm and acting ou the shoe, the lifting-lever, and the chainI connecting it with the gag-iron, these members being constructed and operating in combination, substantially as hereinbefore set forth, to allow the guards to rock or r'oll upward, while' the cutting apparatus is elevated above the ground. l

5. The divider-iron, constructed as hereinbefo're described, with a transversely-slotted socket, incombinatiou with the divider-finger inserted. therein, and the screw-bolt passing through the slot into the` finger, for permitting said finger to be rolled and secured in any desired position, substantially as and for the purpose hereubet'ore-set forth.
