UNITED STATES EDWARD M. KRUM, OF OLD OHATHAM, NEW YORK.

MOWING OR REAPING MACHINE.

SPECIFICATION fonning part of Letters Patent No. 412,274, dated October 8, 1889.

Application filed September 30, 1886. Serial No. 214,921. (No model.)

To ntZZ whom it 722 603, concern:

Be it known that I, EDWARD M. KRUM, a citizen of the United States, residing at Old Chathain, in the county of Columbia and State of New York, have invented certain new and useful Improvements in Mowing or Reaping Machines, of which the following is a specification.

My invention relates to improvements in mowing or reaping machines; and it consists of the devices and parts and combinations of devices and parts, hereinafter particularly described, and specifically set forth in the claims.

The objects of my invention are to provide in mowing or reaping machines certain means by which the driver can easily and at will control the operations of operating parts in the same, and also render certain parts more effective than heretofore; and, further, to combine certain elements with certain operating parts of the machine, whereby more advantageous operations will be had than heretofore, all of which will be hereinafter fully explained. I attain these obj ects by the means illustrated in the accompanying drawings, in which there are twelve figures, in all of which the same letters of reference refer to like parts throughout the several views.

Figure 1 is a front view of a machine embodying the improvements in this invention. Fig. 2 is a rear side view of the same. Fig. 3 is a view from above of the same. Fig. 4: is a side elevation of the same with one of the driving-wheels removed. Fig. 5 is an enlarged view of the gear mechanism, drivewheel, axle-connections of the frames, and other co-oper'ating parts. Fig. 6 is another view of the gear mechanism. Fig. 7 is an enlarged view of the adjuncts of the cutter-bar shoe and crank-shaft. Fig. 8 is a view of the crank-shaft connection with the cutter-bar from above. Fig. 9 is a sectional view of the pitman-wrist-pin box and sickle-bar pin. Fig. 10 is a side view of the wrist-pin box or hearing. Fig. 11 is a sectional view of the same, taken at line 1, Fig. 12. Fig. 12 is a sectional View taken at line 2 in Fig. 10.

Referring to the drawings, A A are the driving-wheels, and B is the main shaft or axle on which these wheels are loosely mount ed. This axle has its hearings in sleeve 0, and tongue-frame D connects pole D with said sleeve in the manner usually practiced by the trade. Wheels A Aare each held in connection with the axle or shaft B by a friction-clutch E.

A floating frame composed of portions F F F (shown by full and dotted lines in Figs. 1,

2, 3, and 4.) is arranged relatively below the axle-sleeve C and ton gue-frame D. This floating tongue-frame is preferably made with its port-ions F F F connected as one piece and arranged relatively in the form of a triangle below the axle of the machine, and it is jointed with the axle or its sleeve by ears ff, Figs. 1, 3, 4., and 5, so as to be capable of vibrating vertically to elevate or depress its forward end, with which the cutting mechanism is connected. Portion F, of this frame runs diagonally from ear f to the front end of portion F, which holds the crankshaft C, and portion F is ext-ended roan wardly from the forward end of the crankshaft in a direction relatively parallel with the sides of drive-wheels A, and is jointed with sleeve C by ear f, as shown in Figs. 1, 3, and a, and portion F is arranged relatively below axle-sleeve O and extends from ear f of portion. F to ear f of portion F A bracket F is extended rearwardly from portion F for supporting one portion of the gear mechanism, Figs. 1, 2, 3, 4:, 5, and 6, for imparting motion to the crankshaft. The end portions 0 c of portion F serve as bearings for crankshaft C. Bevel-gear G is connected with axle B so as to revolve with it.

Supported from bracket F extended from portion F of the floating frame, Figs. 5 and 6, is the internal gear G and'bevel-pinion G (preferably cast in a single piece,) mounted on a suitable spindleg, supported from bracket F and pinion g, working with the internal gear G, and suitably connected with sprocket-wheel H and mounted on a suitable spindle and also supported from bracket F The revolution of bevel-gear G will ,thro ugh bevelgear G and pinion g, revolve sprocketwheel H.

Secured to the rear endof crank-shaft C is sprocket Wheel H, which is geared with sprocket-wheel H by endless drive-chain H and secured to the front end of the same shaft is the balance crank-wheel E, which operates, through a pitman, the sickle-bar.

I is the inner shoe connected with suspended arm I, which latter is suspended from portion F of the floating frame by ears 1' 2', Figs. 3, 4, 7, and 8. The shoe I being thus suspended by means of its arms I from the portion F of the floating frame, it can be readily oscillated from the latter in either direction, so as to carry the shoe sidewise upward from the ground and return.

Secured to shoe I is the finger-bar J, in which works the sickle-bar K. A wrist-pin j, secured with balance crank-wheel E, operates with a pitman to impart to the sicklebar a reciprocating motion. When the shoe I,

by its arm I, is oscillated outwardly and upwardly, it wilLcarry with it the entire cutting apparatus and elevate the outer end of the 1 shown in Figs. 1 and 4. The pressure of the same accordingly.

In the nose I of shoe I is secured the; This caster-wheel is connected with the nose of said shoeby the angular bracket M, the horizoncaster-Wheel L, Figs. 1, 3, and 4.

tal limb m of which is pivoted to bracket m at the end of nose I while the vertical limb m is slotted and provided with an adjustable spindle m on which the caster-wheel revolves. By means of a screw-threaded nut on spindle m the latter can be adjusted at will to different heights above the surface of the ground, so as to carry the shoe at a .corresponding distance above the same, and by the pivoting of the horizontal limb of bracket M with the shoe the caster-wheel is rendered free to vibrate horizontally.

Secured to the rear side of shoe 1, and proj ecting outwardly from the same, is the curved lifting-arm N, Figs. 1, 2, 3, 4, 7, and 8, having groove n for receiving lifting-chain n. Chain 71. connects wit-l1 the volute-shaped lifting-cam Of This cam is connected with gear 0', (preferably a bevelgear,) and is mounted on a spindle held by a suitable bracket 0, projected upward from frame D, as shown in Fig. 4.

Pivoted to bracket 10, projected upward from tongue-frame D, is segment-gear P, working with gear 0, connected with volute cam 0. Made with the segment gear-piece are ratchet teeth p, and lever-handle P, provided with pawl p operated by a lever-latch and connecting-rod in the manner usually practiced by the trade, enables the driver to operate at will the segment-gear and through it and its coacting gear 0 revolve the volute cam O to cause it to wind up chain n, and thereby cause the arm I of shoeI (which carries the cutting apparatus) to swing upwardly and outwardly by its ears z' z from portion F of the floating frame, when the cutting apparatus will be elevated from a horizontal position to a vertical one, when the cutting apparatus can be readily moved to a short distance past a vertical position, so as to be slightly inclining, and thereby obviate the use of a locking device for holding the said cutting apparatus up, and when the cutting apparatus is turned up from a horizontal position the curved lifting-arm N will be in reversed position on opposite side of portion F of the floating frame, with the end of liftingchain (connected with the shoe) relatively inward past the line of arm I, while the opposite end of said chain will have contact with the external portion of the volute cam. A return of the cutting apparatus to a horizontal position will be 'eifected by reversed operations of the handled lever P.

Q is a duplex lever (shown in Figs. 1, 2, 3, and 4) arranged relatively forward of the drivers seat, so that both its treadles q q can drivers foot on the forward treadle q will depress the forward end of the floating frame, and consequently shoe I and the heel end of the cutting apparatus carried by it. When the pressure is transferred to the rearward treadle q, the forward end of the floating frame will be elevated, when the shoe and heel end of the cutting apparatus will be correspondingly elevated. When the forward treadle q is operated at the time lever-handle P is moved to a short distance, the heel end of the cutter-bar will be kept to the ground, while the outer end of the said cutter-bar will be raised to pass any projecting substance; but

when rear treadle q is depressed and leverhandle 19 is idle, the heel end of the cutter-bar will be raised, so as to pass overany projecting substance at or near the heel of the cutterbar. Byoperating lever P to a short distance at the same time the rear end of the duplex lever Q is depressed the cutter-bar will be raised in its entire length to a corresponding position above the ground. It will therefore be readily understood that by means of the lifting mechanism operated by lever P and the duplex lever Q the driver has full control of the cutting apparatus, and can, at will, elevate or depress the same, or raise or depress its outer end only, or only elevate or depress its heel or shoe end of the same, as may be desired.

R is abifurcated draw-bar having its upper end supported in a suitable loose manner from pole D, while the ends of its limbs 1' 'r are jointed to the diagonal portion F of the fioatingframe, as shown in Figs. 1, 3, and 4. By this bifurcated draw-bar the draft of the animals is applied directly to the floating frame instead of to the main frame or pole, and this floating frame will not be in the least affected by-the relative rise or fall of the pole when the machine is being drawn over uneven surfaces of the ground, while the shoe I of the cutting apparatus will be maintained to the elevation set by the adjustment of the casterwheel without being materially raised or lowered by the draft of the animals or the movements of the pole. 1

With the means of applying the draft of the animals to the machine the pole is employed simply to guide the machine for turning the same and for properly supporting the devices which are attached to the tongueframe D.

Mounted on standard 8, projecting above the tongue-frame, is drivers seat- S, which is pivoted to the horizontal end portion of standard s, so as to be capable of turning in direction of arrow 2. On the lower side of seat S are gear-teeth t. (Shown in Fig. 2, and indicated by dotted lines in Fig. 3.) These gearteeth operate gear T, Figs. 1, 2, 3, and 4, mounted on shaft 11., which is supported by brackets a a, connected in a suitable manner with standards. Secured to the forward end of shaft 16 is a crank-lever T, and jointed with the free end of this crank-lever is rod T which is jointed with the horizontal arm '2; of dog V, Figs. 5 and 6. This dog V is pivoted in a suitable manner with bracket F as shown illustrated in Figs. 5 and 6, and when arm n is in a horizontal position, as shown by full lines in Fig. 6, this dog will be out of engageinent with the cogs of the internal gear G; but when said arm is depressed the dog will engage with said gear and hold the same from revolving WV is a spring connecting with seat S and its standard. S in direction of arrow 2 and hold it turned with its front side toward the gear G, and when the seat turns in direction of arrow 2 the gear made with the seat will operate gear T, actuating crank-lever U, and effect a depression of the arm Q7 of dog V, andthrow the latter in with the teeth of the internal gear G and hold it from revolving; but wh en. the seat is turned to position facing the front of the machine the gears t T will, through cranklever T and connecting-rod T operate to hold dog V out of engagement with the teeth of said gear, so that it can fully revolve. At a side of the seat is fixed a reacting lever '0, Figs. 3 and t, which projects forward so as to have bearing along the side of the drivers leg, to aid him to hold the seat facing the front of the machine. lVhenever the seat is turned so as to face toward gear G, the dog V will be thrown into engagement with the internal gear and hold the same from transferring motion from the bevel-gear G to the cutting apparatus. It will be readily seen that should the driver from any cause fall from the seat the spring XV will turn the seat on its pivot and thereby cause the gear mechanism T t and crank -lever T to throw dog V into engagement with the internal gear G, and thereby stop the movement of the cutting apparatus and prevent the driver from being injured by it. Another advantage is that when the driver is off the seat the seat will be in position for holding the dog V in lookingengagement with gear G, when the driving This spring tends to turn seat wheels will be held from revolving forward. In this case the mechanism operates as a brake to the wheels, and will check the animals from readily starting olf with the machine in the absence of the driver.

I provide with bracket F Figs. 5 and 6, an adjustable sprocket-wheel bracket 72, which is pivoted on the stud or spindle g of the internal gear G. This bracket is provided with curved slot 72., which receives the spindle 721 of the sprocket-wheel H. This spindle 71- is made with a shoulder and a tightening-nut h by which it can be readily fixed after the said bracket 71-1138 been adjusted. By means of this adjustable sprocket-wheel bracket the slack of the sprocket-chain can at any time be taken up.

X, Figs. 2 and 3,is a shifting cam mounted on sleeve 0 and working in notch w, made in portion F of the floating-tram e. This cam has a throw sufficient to move the floating frame to a distance sidewise from the bevelgear G equal to the depth of the cogs in the same, so as to move the bevel-pinion G out of engagement with said gear, when the driving-wheels of the machine will be free to revolve with out imparting motion to other mechanism of the machine.

Y is the pitman for connecting the wristpin of the balance crank-wheel E with the reciprocating sickle-bar K. This pitman consists of the pivoted lever-jaws 3 y and tightening screw-bolt y, Figs. 7, S, and 9. The long ends of these lever-jaws are made with recessed jaws ,2, preferably conical-shaped, as shown in Fig. 9, and they hold the conical ends of a pivot or pin, which passes through the car 70, Figs. '7 and 8, made with the heel end of the sickle-bar. The opposite ends of these lever-jaws are made with conical cupshaped recesses e and receive the conicalshaped box-bearin gs Z of the wrist-pin. These bearings are preferably made as illustrated in Figs. 10, 11, and 12, in which two opposite sides are slot/ted in direction of the axes of the bearings to within a short distance from being through the she1l,while with one of these slotted sides is slit 5 through to the bore of the bearing. Vlhenever either the conical ends of the pivot-pin or those of the bearing Z become worn the pitman can be readily tightened on the same by screwing the nut on the tightening-bolt 3 The track-clearers l are held in sockets i suitably connected, as praeticedby the trade, with a bracket i which is adjustably-pivoted to the heel of the outer shoe 1*, and is held with the same by a screw-bolt, which can be loosened and tightened at will to permit the adjustment of the track-clearer to any desired position for clearing a good track.

Connected with the main frame or pole and attached to the same and arranged between the same and the floating frame is the elastic holder consisting of a suitable spring S secured to the main frame or pole, and a suspension-chain S or jointed rod,) which con- IOC nects the said spring with the floating frame. This device operates to give to the forward end of the floating frame" an elastic support, so as to cause the shoe I to bear more lightly on the ground than it would without this support.
