To all whom it may` concern.-

^ Be it known that I, DAVID B. ARNOLD, a

l citizen of the United States, residing at Terre VIQ `Haute, in the county of Vigo and State of Indiana, have invented certain new and useful `Improvements in Traction-Engines; and. I

eclare the-followin to be a full, clear, and

exact description. of t e invention, such as Vwill enable others skilled in the art to which it appertains to make and use the same.

' My invention relates to improvements in traction-engines; and it consists in the novel mowing-mac me may be driven and also means whereby a reapm -mac an elevator or other parts of ine may be driven.

A furt er object of the invention is to improve and simplify the construction and operation of machines of this character, and thereby render the same more e'mcient and durable in use and lessv expensive to manufacture.

The above and other objects of the invention are attained by means of the constructlon illustrated in ,the accompanying drawings, in Which- Figure `1 is a top plan view' of my improved tractlon-engine, showing a plow mounted thereon. Fig. 2 is a vertical longitudinal .Y sectional view' through the same, taken on the plane indicated by the line 2 2 in Fig. 1.

Fig. 3 is a vertical transverse sectional view taken on the plane indicated by the line 3 3 in Fig. 1'. Fig. 4 is a similar sectional view takenon the lane indicated bythe line 4 4. in Fig. 1 and slliowing thegearing for `operatin the cutter-bar of a mowing-mac e. Figs. 5 and 6 are pers e'ctive views of the coacting members of tlie clutch device upon one of the drive-wheels, and Figs. 7 and 8 are similar views of the coacting members of the clutch device upon the other-drive-wheel.

construction, but, as shown, is of substantially rectan channel meta beams. `Said `frame. is .supy .ported at its front upon steerin -wheels 2 and at its rear upon drive-whee s 3.. The

steering-wheels 2 are sultably journaled upon. spindles provided at the. ends of a front axle 4, which is plvotally mounted at its center beneath the front end of the frame 1,y asy clearly shown in 2 of the drawin s. lhe

kin -bolt or Aivot-shait 5 of theax e 4 kexten s verti'ca ly throufgrh suitable. bearings 6 7, rovided upon the ame 1, and man angu ar brace 8, as seen in Fig.- 3.0i the draw-l secured a bevel-gear 9, which meshes with ings. Upon the upper end ofthe' shaft 5 is.

ismounted in ear-f ings 12, provided u on the brace 8: A hand-.- Wheel 13' is secure upon. the endofthelaston a rearwardl -exmentioned shaft for the purpose oi` steering the machine. It will be seen that whenV this wheel is rotated the axles 4 may be swung v1n either direction, as desired.

'The drive-Wheels?, have their hubs loosely' mounted upon the ends of the rear axle 15, which is journaled in suitable bearmgsl,

secured adjacentto the rear of the frame 1. Each of the wheels 3 is adapted tobe locked to vthe shaft 5, ,so-as' to rotate therewith, by -a suitable clutch device. In Fi s. 5 to8,"in-

ets 17, so as to p'ermitthesaid hu to serve as one member of the' clutch. .Theother v- 'member 18 is'slidably mounted uponthe rear axle and has an annular enlargement or flange at one end,from which projects an annular series of studs 1.9,Wh1ch arel adapted to sey enter the sockets or recesses 17 ,formed in the hub 14, so as to lock said members together. The member 18, while dinally upon the shaftfso as? to permit the studs 19to be .moved into-and outv of the sockets 17,is keyedto rotate with the shaft 15,`as shown at 20, and the member 18 is forced toward the other member o the clutch, and thereby, held normally m its free to slide longitulocked position by means of a coiled spring 21, which surrounds the axles and is ccnined between said members 18 and an annular collar formed or secured upon the axle.

The clutch device shown in Figs. 7 and 8 of the drawings is similar in construction to the one just described. Instead of providing a stud-and-socket locking connection between the two members of the clutch the members 22 23 in this form are similar and each consists of an inner and an outer annular row of ratchet-teeth, the teeth of each row being inclined in opposite directions and the teeth of the' corresponding rows in the two members being also inclined in opposite directions, as clearly shown in Figs. 7 and. 8.

The members 18 and 28 of the two clutch devices are each formed with annular grooves 24 to receive the forked or bifurcated arms of the bell-crank levers 25, which are pivo ted in brackets 26 provided upon the frame 1. The bell-crank levers 25 have their other arms connected by links or rods 27 to operatinglevers 28, mounted at the front of the frame 1 Within convenient reach of the operator.

The axle 15 is driven from the countershaft 30, which is mounted in suitablelbearings upon the frame 1 and may be connected up in any desired manner with any suitable form of'engine or motor mounted on the frame 1. In order todrive the axle in one direction, I secure upon it .a gear 31, ,which meshes with a pinion 32, loosely mounted upon the counter-shaft 30, and in order to drive it in the reverse direction I sprocket-chain' 33, which is passe about a sprocket-wheel 34, secured upon the-'axle 15, and about a' sprocket-pinion 35, loosely mounted upon the counter-shaft 30. The

opposing vfaces of the pinion 32 and sprocket'.v

35 are provided with clutch members' V36, either of which is adapted to be en `a red by ceac-ting clutch members 37, provi e upon' a sliding hub 38, whichfis mounted u'pnthe counter-'shaft 30. This clutch-hub 38 is` form'ed with an angular groove to receive the bifurcated endv of an operating-lever 39, by means of which the clutch-hub 38 may be shifted to connect or disconnect either the direct or the reverse driving-gear just described. v

In Figs. 1 and 2 of the drawings I have shown a plow 40 mounted upon the rear of the frame 1. As shown,` this plow consists of two parallel beams 41,.which are lconnected together and spaced apart by cross-bars 42, upon the lower endof each of which is a plowshare 43. Thisplow is adjustably: mounted by pivoting it upon the rear end of a swinging 'beam'44, which hasl its opposite end pivotally mounted upon one side ofthe frame 1,

as`shown at 45. The pivotal connection of the plow to the beam is preferably effected bypassing a pivot-bolt 46 throughgalining openings formed in' thejsaid beam. and in rovide a ably mounted rotary disk colters 49, which are disposed in front of the plcwshares and are preferably of the usual form and construction.

In order to raise and lower the plow and hold it in an adjusted position, I providel a flexible cable 50 and connect one of its ends to the rear cross-bar 42 of the plow and its other end to a winding device mounted in the frame 1 at its front end. The cable or similar flexible connection 5() passes over a `guide'- pulle 51 in the forked end of a brace 52, whic 1 is pivotally mounted, as shown at 53, upon the frame 1, so that it may be swung inwardly and out of the way when the low is disconnected from the machine. T e forward end of the cable,50' is secured to and wound `upon a drum 54, which is secured u on the shaft 55 of said'winding` device. T is sl'aft 55 is ourn a'led in suitable'bearings provided upon the frame l and has fixed thereto one member56 o'fa clutch device, the other member 57 of which is adapted'to slide longitudinally upon said shaft 55, but is prevented from rotating therewith b the engagement of longitudinally-extenr ing arms ,59 with slotted guide-bracketsn 60. As shown, these. -arms 59 are formed f integral with a plate`61, which is secured upon the outer face of theclutch member 57 and has at itstop a prdjecting lug or arm 62, to which is pivoted'k.

an operating-lever 63.

member 57 longitudinally u" on the shaft 55 to disengage it from'the oter member 56, with which it is held normally engaged by means of a coil-spring 65. Said s ring surrounds the shaft 55 and is'confine between the member 57 and one ofthe bearings of said shaft.-

vided upon a hand-lever 68'. he lever 68 is loosely mounted upon the shaft 55, and the pawl 67 is slidably mounted ina suitable .plate 69, which is secured upon said lever.

his plate has guid-lugs 70 bent upwardly from its central portionfsaid lower lug 71 bcing apertured to receive the'pawl 67 and havmg a fportlon bent inwardly to engage .the outer ace of the ratchet 66, and thereby hold the 'lever 68 adjacent to said ratchet, and said lug 70 being a ertured to receive an operating stem or ro 2172, which is a acbed'fto the pawl 67 and has its upper engl .3 bent at right angles and projecting through a slot 74,

The latter has one of v` its ends formed with a'handle and its other end pivoted upon a bracket 64, which is se- :o5

Upon the member 56 of the clutch device is formed or secured a ratchetwheel 66, which coacts with a )awl 67, prof Een into engagement with the ratchet 66 by a' springr 75, which surrounds the lower portion of the rod 7 2 `between said pawl and the lug rif.

it will be seen that b pulling or pressing upwardly upon the en 7 3 of said rod the pawl may be disengaged from the ratchet 66 to permit the lever to be rotated without actuating the clutch member 56, and hence the shaft 55. .In order to control the rotation of the shaft 55, particularly when the cable is unwound from the drum 54 to lower the plow, I rovide u on the shaft 55 a brake wheel or lub 76, w 'ch is surrounded and engaged by a friction brake-band 77. This band is preferably formed of resilient metal and -has one of its ends secured upon the cross-bar 7 8` upon the frame 1 and its opposite end bent to forma foot-piece 79, by means of which it may be readily tightened upon the periphery of the friction-wheel 76, as clearly shown in Fig. 2 of the drawings. In elevating the -plow it will be seen that the ra' net-lever 68 is oscillated. When moved forwardly, its pawl 67 slips over the teeth of the ratchet 66, and when moved .rearwardly it rotates the clutch member 56, and hence 'the shaft 55 and drum 54, to wind the\cable 5() upon the latter, the teeth of the clutch member 56 slipping over .the teeth of the member 57, as will be readily understood by reference to Fig. 1 of the drawings. When 1t is desired to lower the'plow, the clutch-lever 63 is shifted to disengage vthe member 57 from the member 56, and the pawl 67 is disengaged from the ratchet 66, so that the weight of the plow will rotate the drum 54 and its shaft 55, the movement of the lattermentioned elements being readily controlled by means of theengagement 'of the friction brake-band 77 with the wheel 76, as explained.

When itis desired to use the machine for operating a mowin -machine instead of a plow, as previously described, the plow is removed and the necessary parts o'fa mowingmachine are connected to .the frame 1, as shown in Fig. 4 of the drawings. vThe sicklebar 80 of the mowing-machine' has itsl pitman 81 connected to a wrist-pin 82, provided upon a crank-disk 84, which is securedupon the forward end of a shaft '85. The latter is mounted in a downwardly and forwardly inclined position inbearings 86, provided upon bracket 87 which depends from one side of the frame 1.v Upon the shaft is secured a' bevel-pinion 88, which meshes with the bevel-` gear 89, which is mounted to rotate upon a stub-shaft 9 0, provided in the bracket 487. Secured upon the -gear 89 is a sprocket-wheel 91, which is connected by a s rocket-chain 9 to a sprocketheel93, which is secured 1Jon the counter-shaft 30. It willbe seen that when' the shaft 30 is rotated itsv moyement will be imparted through the gearing l ust described to the crank-disk 84, so that the cutter or sickle bar of the mower will be reci rocated.

hen the mechanism for reaping grain is mounted upon or connected to the frame 1*, the elevators and binders thereof may. be driven by a sprocket-chain, (not shown,) which may be passed about a sprocket-wheel 94, secured upon the outer ends of the counter-shaft 30, as willl be readily understood.

From the foregoing description, taken in? connection with the accompanying drawings,

the construction and operation ofthe invention will be readily understood without re- .A

Soif

quiring a more extended ex lanation Various changes in the orm, proportion, and the minor detailsof construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described .myinvention what I claim asnew, and desire to secure by Let-y 1. A traction-engine having a frame, a. driving counter-shaft mounted thereon, a driving aXle-shaft,'connecti11v -gears between the counter-shaft and the a e-shaft to drive v 'the latter in either direction without reversingthe counter-shaft, each of said connecting-gears including an element loose on the" counter-shaft, a clutch member on the counter-shaft to lock either of said loose elements thereto at will, a stub-shaft, a bevel-gear rotatable thereon, driving connections between said stub-shaft, and said counter-shaft, a sec-4 enf ond shaft' a bevel-pinion onv the latter gaged with said bevel-gear, and a crank-disk on the second shaft, to Ivoperate the pitman of' a mowing-machine, substantially as described. e

2. The combination of a frame, wheels for supporting the same, means for4 driving said wheels, a counter-shaft, a'bracket upon said frame, a stub-shaftin gear rotatably -mounted upon -said. stubshaft, sprocket-ham gearing between said bevel-gear and said counter-shaft, a second shaft,l a .bevelinion upon the latter in mesh with said beve -gear, a crank-disk u on said second shaft, av wrist-pin upon sai crankdisk, a tooth-bar of a mowing-machine, a cutter-bar mounted in said tooth-bar, and a pitman conn'ecting said cutter-'bar and said wrist-pin, substantially as described.
