MARTIN L. ANDREWS, OFMILLERTON, PENNSYLVANIA, 'AssrGNoR 0E oNE-'HAJL'E 'To LUELL J. ROBERTS, 0E SABINsvILLE, PENNsYEVANIA p REVERSIBLE WHEELER PLoWJ I Application filed July 1,

To all whom t may concern:

Be it lmownthat I, MARTIN LIANDREWS, a citizen of the United States, and residing at Millerton, Tioga County, State of Pennsylvania, have invented certain new and useful Improvements in Reversible Wheeled Plows, of which the`following is a specication.

The general object of the present invention is to provide a plow of the reversible type utilized in plowing back. and forth across a field, the successive furrows being parallel and adjacent, in which are embodied improvements rendering the same eflicient and convenient in use.

One specific object is to provide a wheeled plow with a plurality of reversible plowing devices. Another object is to provide a plow of this class in which the reversal of the plows at the end of the furrow is brought about iquiclly and easily, the power necessary being obtained from the horses or tractor employed to pull thesame. further object is. to provide suchia plow ink which the reversal of plow blades is effected by the l .direct raising and lowering ofthe plow beams, which may be done quickly, not only at the end of the furrowbut Aat any point therealong if desired. The invention also has for an object the provision of Vnovel4 structure by means of which the plows are maintained at al constant distanceapart in the plowing operation, but which mechanism permitsy the plows vto move in'4 unisonl from sideto side slightlyV due to inequalities in the ground and to avoid rocks, etc. f

The invention may be embodied inivarious Y -forms and one satisfactory formas disclosed '6-6 VoA'fFigure 2; and v inthe kfollowing. description and 'in the'4 accompanying drawings, in which:

AFigure 1 is'a top view of a'two-beampl'ow, the plowsbeing in raised ,or inoperative .position; y Y i -jr Figure 2'is a similar-view but showing the plows in lowered or cutting position;

tion lfull lines `and in lowered or cutting position in dotted lines.

The frame of the plow comprises lthree longitudinal parallel members 10, 11 and 12 I secured together vat their forwardends by cross-pieces 13 and 111 and beingfconiiected at theirrear ,endsl bythe 'axle' 15`r which passes through bearings ineach longitudinal member and is freely rotatable relatively to lthe frame.y Wheels 116 ofjthe usualgfrarm implement type are mounted von theenrdsof` shaft 15A and' parallel linkage comprising i members 19, 20,21 and 22 maintains sleeves 17 aconstant distance apart, the' side menibers 2O and 21 of thelinkage being slotted at 23, and 241 respectively to receive 'pins 25 andv 26 projecting upwardly from sleeves 17. To 4the rear end of each plow beam Vis rigidly vsecured av right lia-nd plow 27 vand a left hand plow-128 ai'idAto4 the. frontlendgof each beam is secured a crosshead member 29, the

endsy of each of which are adapted toslide longitudinally of theplow body in slotted members 30, through llimited distances. Each of the plow beams' is grooved at v31, clearly illustrated inFigure-t, this groove making a quarter turn in its length and hav- Ving extending downwardly thereinto a lug 32 integral with .a 'non-rotatable' sleeve 17. Each beam rotates through -o when the crosshead attached thereto, and which vlimits i l its motion in both directions, ismoving from y .one end of slotted member 30 to the other.`

Each of the sleeves 17 is latched to the corresponding crosshead 2,9 Aby a pivoted latchmember 33 and each of the crosshead members 29 isnormally latched tothe cross I piece 14 by a U-shaped latch member Bthaving a handle 35 integral therewith and Ijourynaled. upon shaft 36, clearly illustrated: in

Figure 6.; Immediately in frontof each of which it isfrigidly secured, rod 39, ring member 40 to which the'rod39 is rigidly secured, and arm 41. extendingrearwardly and passyarms 35 is oney portion 37 of a.v trip member lwhich compris'esarm 37, ring y,member 3 8-to f-iiigzimmediately. under thegforwardfend of one of the latch members 33. The two tripping members are similarly `but oppositely formed and each rotates on shaft 36v as an axis when the corresponding lever 35 is moved forwardly. It will be apparent from this description that if the right hand lever 35 is moved forwardly that the right hand crosshead 29 will be released by thelatch 34 and the left hand sleeve 17 will be released, its latchingl member SShaV-ing been'raised by the tripping device. lf the left hand lever 35 be -moved forwardly it will be apparent that the left hand crosshead 29 and the right hand sleeve 17 will be released while the right hand crosshead will remain in position. In Figure 2 -is clearly illustrated the position of the parts after the left hand hand lever has been operated.

The' plow beams tend to fall by their Vown weight from the full line position to the dotted line position, Figure 3, rotating the axle 15 rearwardly and downwardly. Then the plows arev raisedand are in inoperative position, however, they will remain in' such position until one of the hand levers is operated. Assuming that theleft hand hand lever is the one selected it will be seen that the left hand plow beam will fall without moving relatively to its sleeve 17, and hence without rotation. The right hand plow beam has howevernot beenreleased by unlatching the Amember 34 and it has merely swung downwardly about the crosshead Y29 as a pivot'. The vright hand sleeve 1 7 has however moved rearwardly on the plow beam and has causedVV the same to rotate thrOughQOOias the forward end of the plow beam is Vpivotally connected to the crosshead 29, thereby causing the plow 27 to fall into operativeor 'cutting position, as shown vin Figure 7. In this position one of the plows.

is positioned a short distance ahead of the other which vis desirable. The downward movement of the plow beams is limited by the horizontal` bar 42 against which the longitudinally extending portions of thelaxle strike. .This bar 42 is fastened to the vertical post 43 bolted to the center bar 11 of the frame. A #As the plows'and plow beams are of considerable weight, means is provided for raising them to inoperative position without requiring strenuous work on the part of the operator. rllhis means throws the exertion necessary uponvthe draft horses or tractor connected to. the plow. .Rigidly secured to each offthe'wheels is a notched ring 44 and bolted to each laterally extending U shaped yportion of the axle in such manner as to be freely rotatable is a bar 45 having a hookedA end 46 in positionA to engage one of the notches of the ring 44, and having at its inner endy an arm 47. To theA ends of each ofthe arms 47 is connected. a cord or rope f 48` which extends.. forwardly to a position plow iii-to. operative. position.k

where it may be conveniently pulled by the operator.

yVv'lhen one of the levers 35 has beenmanipulated to lower the plows, the hooked arm 46 is thrown rearwardly, asI illustrated in F igure 3, and remains in this position'iintil the operator, by pulling on cord 48, throws it forwardlyso that it engages one of the notches in the ring 44. As both hooks 46 simultaneously engage rings 44 the axle 50 will be rotated from its substantially horizontal position to its substantially vertical position, lifting the plows from operative to inoperative position and sliding the left hand cross head 29; and the right hand sleeve 17 forwardly until they are again latchedf 'in inoperative vposition as shown in Figure 1. As the plow beams reach their uppermost 'or final and inoperative position the arms 47 of bars 45` strike cross piece 22 thereby liftinghooks 46 from thev notches at the proper time. This is done when the plgow has reached the end of the furrow and when the return journey isy begun theright hand operating lever is operated to release the plow beams which thereupon fall.k with the left hand plows in operative. position, so that the plow may parallell its former. course and yet the fur-rows be thrown in the same direction.

The invention enables a single operator 'to easily and conveniently plow a field on Va steep hillside, and puts no burden upon him in the manipulation ofthe reversing plows other than that of'operating levers 35 and cord 48. The device is inexpensive and 4not liable to become out of order in any manner. The invention vmay. be made ina variety of forms ofwhich that form disclosed is representative, and isrnot limited in its scope to this exact desi-gn.

Having thus described the invention what .is claimed as new and desired tobe secured by Letters Patent is:

l. In a plow of. the `class described, a wheeled` frame, a rotatable and vertically movable plow beam, right and left hand plows secured to said beam, and connections including, a sleeve throughwhich the beam extends' with a sliding fit, between said beam 3. In a plow of the class,y wheeledv frame, a crosshead having a` limited sliding movement relatively,y to s aidframe,

described, a

a plow beam having one end rotatably secured to said crosshead, right and left hand plows secured to said beam, and means connecting said beam and frame intermediate the crosshead and plows whereby the beam is given a rotary movement as it moves longitudinally with the crosshead, for the purpose set forth.

4. In a plow of the class described, a wheeled frame, a crosshead having a limited sliding movement relatively to Vsaid frame, a plow beam having one end rotatably secured to said crosshead, right and left hand plows secured to said beam, and means, including a sleeve connected to the frame and receiving the beam with a sliding fit, securing the beam to the frame intermediate the i crosshead and plows, whereby the beam is given a rotary movement as it moves longitudinally with the crosshead, for the purpose set forth.

5. In a plow of the class described, a wheeled frame, a crosshead having a limited sliding movement relatively to said frame, a plow beam having one end rotatably secured to said crosshead, right and left hand plows secured to said beam, vand means including a non-rotatable member, connecting said beam and frame intermediate the crosshead and plows whereby the beam is given a rotary movement as it moves longitudinally with the crosshead, said beam and nonrotatable member having mutually engaging portions one of which is spiral shaped for effecting the rotation of tion of its axis, right and left hand plows secured to each beam, and means normally retaining said beams 1n elevated position,

said means comprising two manually operable levers, the operation of one of which permits both plow beams to fall by gravity with the right hand plows in operative position and the operation of the other of which permits both beams to fall vwith the left hand plows in operative position, one plow beam moving axially a greater distance'- v tion, the operation of the other of whichvv permits both beams to fall with the right hand plows 'in operative position.

8. In a plow yof the class described, the

combination with a wheeled supporting frame, ofl two plow beams supported thereon, each plow beam being mounted for rocking movement in a vertical plane and also movement in the direction of its axis, right and left hand plows secured to each beam, and means normally retaining said beams in elevated position, said means in-y cluding two latches normally holding each i plow beam, and two manually operable latch releasing devices, the operation of.l

leither latch devices resulting in the release of three of said latches whereby the plow beams are allowed to fall with either two right hand or two left hand plows in operative position, depending upon the releasing device operated.

In testimony whereof I affix my signature.
