SPECIFICATICN forming part of Letters Patent No. 399,000, dated March 5, 1889.

Application filed November 16, i888- Sorial No. 291,025. (No modeLl Y .To coli whom it Hwy-concern:

Be it known that l, MILO DJBEACH, a citizen of the United States, residing at .Litchield, in the county of Litchfield and State ot Connecticut, have invented cert-ain new and useful Improvements in Hillside-Flows; and I do decla-rc the followingro he a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use tliesarne, reference being had to the accompanying drawings-and to the letters and figures of ref-.

one side. and decreased when it stands on the other side. These results are accomplishedv by the mechanism shown inthe drawings, in Which- Figure l is a sideelevation of an iron-beam plowr embodying my improvements. Fig, 2 is a Vertical longitudinalv section of the worning parts. Fig. 3 is a horizontal sectionthrough the shaft. Figtis a Vertical oross-section through the handles and the duplex hook. Fig. 5 is a View of the double eccentric for' shifting the jointer. Fig. 6 shows a-modied form of the same for shitting the colter.

Figs. 7, 8, and 9 illustrate the duplex hook. Fig. 10 is a cross-section of the tubular bean ing and the colter, taken on line :l: zg, Fig: li. Fig. 11 shows the scctoigear. Fig. l2 is a crosssection of the jointer on line y y, Fig. 2. Fig. 13 is a plan of the crank-head. Fig. 14 is a View of the colter; and Fig. l5 is a crosssection of the beam on line e e, Fig. l(

The same letters refer to the. same parts in all the igures.

the standard at c, and also to a cross-har, D, which is fastened by a holt, d, to a lug or ear, a,

projecting rearwardly i'rointlie standard. Between the handles is pivoted the duplex hook E, which is composed of a huh, e, having two arms, e', meeting the hub at an obtuse angle. On the outer end of each arm is an upwardlyturned hook, e2, having its upper edge down- Wardly 'inclined toward the rear, as shown in Fig. S. Along the upper .side of each arm runs a rounded rib, e3. From theupper face foi the hub project one ormore studs, et, which enter corresponding holes in the end of a headed sleeve, F, and thus look the hook and sleevelogether. Other means of accomplishf ingthi's will be'readily suggested. The sleeve iscylindrical and fits into a bearing formed in the cross-har D. The upper end of the sleeve is fiattened on opposite sides to enter an oblong slot, g, cut in the plate G, which rests on the upper face of the cross-bar D. Through the huh e and the sleeve-Fv passesa bolt, H, which has a broad flat head, h, bearing Aagainst the under side of the hook E. The opening in the hub e is larger than the bolt, so that the huh is loose on thebolt, which eX- tends considerably' above vthe plate G, and carries a cap, 7L', which may be integral'with the nut h2, or separate from it, as desiredr- Between the cap and the pla-te G is seated a helical spring, H', encircling the bolt., which is thus free to slide axially in the sleeveF, but is normallyheldwith its headholding the hook E in place against the sleeve. The hook can, however,.he sprung slightly away fronti 'thesleeva so that when swung ffroni an opposite position to the other it may ride under one of the small liigs d', which depend-from the under side of the cross-bar Dfan'd serre to loek the hook in place. The lugs ld and the ribs ea are rounded, as shown in Fig-7, so

as to readily be engaged or disengaged by the application of sufficient force.V

On each under side of the mold-board is a catch or lugo, having one face beveled, as shown in Fig. 4. The edgeof the lug is also inclined, to correspond with the edge ot' the hook e2, as shown in Fig, 8. WV hen the plow is to be reversed, the plowinan pushes the projecting arm of the double hook E. with his foot, which disengages said hook from the' lug b on the mold-board and from the lug d on the crossbar and throws it around into its other position, whereit is locked hy the lug the hook to have sufficient play to act in this' manner, and the inclined edges of the hook e'2 and the lug b have a tendency on meeting to throw the arm'e forward and so avoid any danger of disengaging it from the lug d.

\Vhen the duplex hook is swung frein one I side to the other, it oscillates the sleeve F and the plate G. The front edge of sai pl'ate'is a segment ot' a circle struck from t ecenter of the sleeve F, and is cut into bevel gearteeth g'. These mesh with. a sector gear wheel, I', on a shaft, I, which is stepped in a bearing, d?, preferably formed in the crossbar D, and extends upward along'the back of the standard, as shown, its upper end be ing received in a semi-cylindrical socket, j, formed at one end of a double eccentric, J. rIhe shaft I is secured in the socket by a bolt, as shown. socket allows the shaft I1 to be stepped in the bearing d?, andrthen dropped laterally into the socket and fastened. At the end of the double eccentric ,J is formed. .a cup-shaped hub, 7", cylindrical on the outside. The axis of this hub is in line with the axis of the socket j and the shaft I, so that the hub revolves concentrically with the shaft I.

The double eccentricJ consists of a cylindrical shaft united tol the sooketgl at one end and to the hub j at t-he other, but so placed with its ends on opposited sides of the axis of the shaft'I and hub 7"V that the axis of the eccentric J crosses the axis of the shaft I and hub j preferably about midway of the eccentric J. 'hen the shaftl is rotated, the ends of the eccentric .I will'describe small circles around the axis of the shaft. The hub j -is held in a cylindrical bearingformed in a horn, A', which may be castA integral with the beam A, or may be attached to it.l

The jointer is provided with a, stem, K, fit- 5o ting in a tubular bearing, A2, formed in the beam A'. A transversebol't, a', engages with sys -a groove, 1c, cut partially around thestem K, and prevents any endwise motion of said stem in its bearing. In the upper end of the stern is a diametrical slot, k', whose width is slightly greater than4 the diameter of the double eccentric J, which'is engaged with the slot, as v,shown in Figs. 2 and A3. The axial lines of the shaft I, the eccentric J, and the jointer-steui K all intersect at the point X, Fig. l3.

Upon revolvin g the shaft I the vibration of the double-eccentric causes the stem K to oscillate in its bearing, the angular movement being twice the angle between the axes of the shaft I and-the eccentric.

To the lower end of the jointer-stem is at- The semi cylindrical form of they tac-lied the jointer, composed of a Socke-ted head, K', provided with a setscrew,-\1', engaging with suitable depressions in the stem K for the purpose of adjusting the jointer up and down on the stein. To thehead K are cureda suitable point andilaring wings or mold-boards, as shown, wherebyT the jointer is4 en( bled to lslice off the turf in advance of the plowshare whichever way the furrow is being turned. A single mold-board joiuter may be used, if desired. 'hen the duplexY hook Eis thrown from one side to the other, the sectorgears will be opcrated,and they are so pro- .I portioned that the shaftl lis thereby given a half-revolution. This is sufficient to throw the point of the joint-er over to the side opposite to the mold-board of the plow in a position to properly cut the turf.

In order to automatically swing the elevis to properly adj ust the draft of the plow, a shaft, L, is mounted in a tubular bearing, A, cored out in the plow-beam. The rear end of this shaft projects into the cup-'shaped hub j', where a slot, l, in the shaft engages with a pin, f2, passing diametrically across the hub. The slot and bolt constitute a universal joint, by which the motion of the sha-ft l is communicated to the shaft L.. i

- In the forward end'of the shaft L is a slot, l', which engages with a pin, m,diametrically crossing a cavity in the end of the-short horizontal 'shaft M, mounted in a tubular bearing,

Af?, cored out in the beam A. The shaft M projects out from the end'vof the plow-beam and carries a flat head, M', the front edge of which is a curve. In each side ofthe head is cut a groove, m', concentric with andparallel to the curred edge, leaving a flange, m2, on each side of 'the head. A dog, 'Nhaving a T shaped slot fitting the flange and the grooves, is adjustable along the head by means of the set-screw Frein the front of the dog projects a cylindricalA nose, N.

The clevis O is Ushaped,'and is pivoted to swing horizontally by' means of the bolts P, which are provided with suitable nuts, p, lreceived in slots in the web of the beam A. The

curve of the head M' is struck from theaXis' of the bolts P-as a cen-ter.l In theinner face of the clevis, which has the samecurvature as .the head M', is a groove, o, which engages with the nose N of the dog N.

Then the nose N lies in Ithe axis of the shaft M, it will have no effect' upon the clevis when the shaft is rot-ated; but if the dog is adjusted to one side or the other along the head lVlQthcn whenl the shaft is`rotated the nose N acts as a crank-pin and throws the clevis t oneside or the other, and to an .extent correspondingavith the distance of the nose from the axis of the sha-ft M. In this way the angle of the clcvis to the line of draft can be regulated with great nicety, and is certain to give exactly the same amount of side draft in both positions of the plowshare and mold-board. rlhe clevis is automatically shifted at the same time with the jointer and IOO IIO

scacco bythe single operation of throwing the duplex hook from one side to the other. Under some circumstances, however, it may be desirable or necessary to give more side draft when running the plow in one di-rection than when running it in the opposite direction. To accomplish this, the @levis-hook Q is attached to the clevis O by a bolt, q, passing loosely through one of the holes o in the head of the clevis, and thev sides of the clevishead, are chamfered ott toward the iront and rea-r from aline just back of the bolt-holes, as shown in Fig. 3. This construction permits the clevis-hook to be laterally vibrated, and it is locked in any desired relation to the clevis by means of intermeshing teeth or corrugat-ions o2 q', formed, respectively, on the front edge ot the clevis and the inner face of the slot in the clevis-hook. vThese teetlirun verpartial revolution on lits axis.

tically the entire length ot the surfaces in which they are formed. To adjust the hook Q, the bolt q is removed, the hook is pulled slightly away from the clevis, moved laterally the required amount, and then pushed baekto engage its teeth q with the teeth o2 of the clevis and bring the bolt-holes into line, so'thatbolt q may be replaced. This adjustment oi the clevis-hook will increase the side draft when the clevis stands on one side and reduce it when the clevis is reversed. The side drait can therefore be regulated with great exactness to suit the varying conditions under which the plow is used. A colter may be substituted for the jointer, if desired. lt is shown in the dotted 'line'sin' Figs. l and 2 'and in full lines in Fig. 14. Fig.. 6 shows the eccentric for shitting the colter, and Fig. ll is a cross-section of the colter where Vit enters the tubular bearing A2. The stem R of the colter tapers oft toward the top, so as to be able to vibrate sidewise in the bearing. In front ci the tubular bearing A?r is formed a recesso2 to receive the upper part of the dat blade Rf of the colter. The.. eccentric J', which shifts the colteigis single instead of double, and has a greater throw at its rear end than in front, as indicated by the positions of its axial line relative tothe axial line of rotation. A double motion is thus imparted to the'colter-one ot vibration laterally in the bearing and one of The vibratory motion throws the point of the colter into line with the plow-point. The rotator-y movement brings up the edge of the colter in to a nearly vertical plane, andthereby counteracts the tendency or" the vibratory motion to tilt the colter out of an upright position. The point of the colter lies in the axis of revolution of the stem R, and is therefore not affect-ed 'by the rotatory motion. l

lt will be noticed that the eccentrico .l and i J and theadjustable crank-pin N are so disposed as to be onradeadfcenter whenV the jointer or colter and the clevis occupy their working positions,- so 'that the eccentrics and the pin are in the best position to resist strains,

l and are relieved. from all danger of being thrown out.; of their positions by the stems of the j ointer or colter and the head of the clevis.
