REVERSIBLE PLOW.

SPECIFICATION forming part of Letters Patent N 0. 477,912, dated June 28,1892. Application filed March 17, 1892'. Serial No. 425,233. (No model.)

'To all whom it may concern:

Be it knownthat-I, AUGUST PIRCH, a citizen of the United States, residing at Los An geles, in the county of Los Angeles and State of California, have invented a new and useful Improvement in Reversible Side-Hill and Ditching Plows, of which the following is a specification.

My invention relates to that class of plows in which a right and a left hand plow are secured together rear to rear and pointing in reverse directions.

One object of my invention is to increase 'the efficiency and convenience of operation of this class of plows and to adaptsuch plows for ditching purposes.

A-further object of my invention is to produce a sulky-plow of this class which may be adjusted to the slope of the ground upon which it is used and which, without changing the position of the sulky with relation to the plow, will automatically turn theseat as the plow-beam is reversed, so that the driver will always face the team without any effort on his part to that end.

A further object is to provide convenient means for gaging the depth and width of the furrow which the plow will open.

The accompanying drawings illustrate my invention.

Figure 1 is a perspective front view of my improved plow arranged to operate as a side hill plow. Fig. 2 is a fragmental transverse,

sectional view on line a: a; of Fig. 1. Fig. 3 indicates the line of section. In this figure is also shown an enlarged 'detail of the lower end of the plow-operating shaft with the thrust-nuts and collar in place. Fig. 3 isaplan view of myim'proved plow arranged for ditching purposes. Fig. 4 isa fragmental side elevation of Fig. 1. Fig. 5 is a fragmental sectional View on line 1 y, Fig. 3, looking toward the left. Fig. 6 is a plan elevation of the landside dirt-guard removed from theplow. The position of the plow-standard c is indicated by dotted lines in this view. Fig. 7 is a rear elevation of the beam-adjusting'de vice, showing a second position in dotted lines. A portion of the guide A and a fragment of the beani and truss are shown in this view. Line 2 IejFig. 3, indicates the point of view.

Fig. 8is a fragmentary view illustrating the guide engaging the pawl-head and'the notches Figs. 1, 3, 4, and 5 to contract the view.

My invention comprises the combination of a reversible plow having its beam journaled to revolve, a sulky-wheel arranged atone side of such beam and attached thereto by intermediate means, a seat arranged above such sulky-wheel and ournaled to revolve, suitable intermediate means connecting the plowbeam and the seat to cause the seatto rotate in correspondence with the plow-beam when such beam is rotated, and means for locking the beam with relation to the plow.

My invention also comprises the combination, in a plow, of a horizontally-arranged hoop or band forming a circular beam guide and brace, a truss extending across the center of such guide and secured at each end to such guide, a right and a left hand plow placed rear to rear and having their standards pivotally secured to such truss, a plowbeam arranged substantiallyin line with the truss and pivoted thereto bya pivot arranged at the center of the circular guide, suitable means for guiding such plow-beam around such circular guide, suitable means for looking such beam upon such guide, and suitable means for depressing or elevating the points of such plows to cause them to enter or with- ,draw from the ground.

My invention further comprises the combination of a circular beam guide or brace, a truss extending across the center of such circular guide and having its ends attached to such guide,a plow-beam pivoted to such truss at the center of the circular guide and provided with guidingdevices arranged to engage such guide and slide therearound when the beam is rotated, a right and a left hand plow placed rear to rear and having their standards pivotally secured to-the truss, a sulky-arrn having its inner end-attached to the truss, extending outward 'u nder the circular guide and attached thereto, a supportingwheel adj ustably secured to the outer end of such sulky-arm, a seat-bow provided with a seat and pivotally attached to such sulky-arm,

a sprocket-wheel fixed to such seat-bow at its pivotal point, asprocket-wheel attached to the plow-beam at its pivotal point, a sprocketchain connecting such sprocket-wheels, means for locking the plow-beam in position upon the circular guide, and means for depressing and elevating the points of such plows to cause them to enter or to withdraw from the ground. 7

My invention also comprises the combination of a plowshare and a mold-board, a standard secured thereto,abeam-guide attached to such standard and provided with a suitable pawl-receiving notch and arranged to allow lateral movement of such beam,a plow-beam provided with a suitable guideway arranged to engage such guide to allow lateral movement of the beam,-abeam-adjustinglever pivotally secured to such plow-beam and provided with a pawl arranged to engage a suitable rack rigidly fixed to the beam, such rack, and means for operating the pawls.

The invention also comprises, in a reversible plow, the combination of a right and a left hand plow secured rear to rear, a plowbeam attached to such plows, suitable means for operating such plows, and a sheetkmetal landside dirt-guard substantially conforming to the shape of and arranged to cover the open space upon thelandside of each plow, and

suitable means for securing such guards to such plows.

My invention also comprises various other features and combinations hereinafter fully set forth and claimed.

The circular guide A is formed of a band or hoop of wrought, cast, or forged metal of suitable thickness to secure the desired strength. As illustrated in the drawings, the truss which extends across the guide A is formed of the parallel transverse beams B B, which have their ends I) b firmly secured to such band upon the inside thereof, and are arranged with a space I)" shown in dotted lines in Fig. 3) between them to admit the standards 0 c of the plows'O O, which are secured thereb'etween by means of the bolts 0" c. It will be understood that if the guide A is of cast metal the truss may be cast integral therewith without departing from my invention. 7

The plow-beam D is provided on its under side with the guide bearing and draft-plate E, which is secured to the beam by bolts E, and is provided at its ends with the guideseats e e, which are'arranged to embrace the circular guide or rack A, the lugs e" preventing upward displacement of the beam.

The plow-beam D is pivoted to the truss '3 B by means of the plow-depth adjusting screw-shaft- F, which is provided at its upper end with the crank-arm f, and which passes through suitable holes provided in such plowbeam and plate E therefor and also through the nuts G G, which are arranged above and below the truss B B, and are secured thereto bysuitable means, such as the lugs g g, which are arranged to engage the end of the sulky-arm J and the -'sides.of thetruss-beams B B, respectively, to prevent the nuts from turning when the shaft F is rotated. The shaft F extends below the nut G to a point near the base of the plow-standards c c, to which standards it is connected by means of the braces H H, which are pivoted to the standards by bolts h h, and arev also pivoted to the collar h, which acts as a journalbox for. the lower end of the shaft F. Above and below the collar h are placed the thrustnuts I I, which are rigidly secured upon the shaftF by suitable means, such as the setscrews 2'11.

To regulate the width of the furrow which the plow will open,I provide the lateral.plow-..

beam-adjusting lever K, which is pivoted to the plow-beam D by intermediate means, such as the brace L and pivot Z, and is provided with a pawl k, which has a head which is nearly cylindrical in form and is connected with the body of the pawl by a narrow neck -2, and is adapted to engage the notches a,

which are provided in the top of the guide A for its reception. This pawl is operated by a grip-lever and connecting-rod 7c" and a spring 70".

When the plow-beam is thrown over, as is indicated in dotted lines in Fig. 7, an ordi-v nary-shaped pawl-head would be withdrawn from the notch if the line of draft were suddenly shifted toward the left. vTo prevent this I make the pawl-head it nearly cylindrb cal in form and attach it to the bodyk of the pawl bya neck 2, and I also make the notches a. of a circular form with contracted months. When the lever K is inclined, as indicated in dotted lines in Fig. 7, the pawl-head will be retained in the notch by the contracted mouth of the notch until the lever K is thrown upright.

Fig.8 illustrates in dotted lines the position assumedby the head of the pawl in the notch a when the lever K is inclined to the right. The lever K is also provided with a. pawl M, which is arranged to engage a rack N, which is rigidly fixed to the plow-beam D, and such pawl is operated by the grip-lever and connecting-rod m and spring m. It will be understood that the rack N forms the are of a circle, of which the pivot l is the center. The inner end of the sulky-arm J rests upon the top of the truss-beams B Band is secured in place by the stern of the screw F,'which passes therethrough, and such arm is bent downward and passes out beneath the guide A, to which it is rigidly secured by means of the brace-strap j, which is arranged to hold the arm a sufficient distance below the bottom of the guide to leave a space 6" to allow the passage of .the lug (2" between the arm and guide when the plow-beam is reversed by semtrotating it upon the shaft F. A short distance outward from the guidcAthe sulky-.

arm J is bent at right angles and extends upward. a suitable distance to form a vertical guide 7 for the supporting-wheel guide-brace arm O,which is provided with the'guide-seat O and the anti-friction rollers 0, arranged to slide along the guide j. Above this guide portion j the arm is again bent at right angles and at its end is provided with the nut j", through which the wheel-height-adjusting screw'P screws to raise and lower the wheel Q with relation to the plows C C. The wheel Q is journaled between the two arms q g, which are formed of a single strap of metal bent into U shape and attached to the bracearm 0 by welding or other suitable means:

Upon the top of the outer end of the bracearm 0 and directly over the axle of the wheel Q is placed the seat-bow R,which is reversely bent to form the U-shaped portion r, and the stem of the wheel-adjusting screwP is passed through suitable perforations provided in such reverse bends. The bow'is then bent to the rear and bowed upward and forward to receive the seat 1".. The foot and seat-bow is provided on its outer end with a foot-testis;

To the top member of the reverse bend r is rigidly secured the sprocket-wheel T bybolts 3, and which is connected by sprocket-chain t with thesprocket-wheel T, which is rigidly secured upon the beam D at its pivotal point by bolts 4. The hole 8 in the foot-rest brace S and the hole 0"" in the upper member of the bend 1' of the seat-bow spring B, through which the wheel adjusting screw-shaft P passes, are large enough to allow the said shaft to slip easily therethrough. The screw-threads upon the lower end of such shaft are cut away to form the tenon p, which passes through the lower member of the reverse bend r, the wheel-brace, arm 0, and the top of the inverted U-shaped wheel-arms qq, and is sesecured against removal 'by' the pin 19'. A suitable hand-wheel 19'. is secured upon the top of the screw-stem P. to operate the screw to raise and lower the wheel Q with relation to the plows. I

U is a sheet-metal guard-plate conforming to the shape of and arranged to cover the open space. upon the landside of the plow to prevent the dirt from falling between the plows when in use, which would result in raising the rear plowshare in passing over the dirt which had fallen between the plows and so cause the front plow to run too deep.

In Fig. 4 I have shown a fragm'entof this plate secured upon the rear plow; but in the other views they are removed to expose the construction. to is a screw, which passes through such plate and screws into thelug 21,, which is provided upon the mold-boards. u" are perforations, through which bolts may be passed to secure such guard-plate to the plow-standards in case it is deemed necessary.

In Fig. 3 I have shown the rightand left hand-plows, both pointing in thesame direction to adapt the plow for ditching, the stand bolt c and to the standard'c by the bolth,

which secures the brace H tothe standard 0. When placed in thisposi'tion, the rear portion of the plow isunsupported, and to prevent the operator from tipping over back ward when turning the plow I provide a suitable brace W, which I have indicated by dotted lines in Fig; 4c, and which 'is simply theplow-standard and landside connected by a diagonal brace w. It'will' be understood that in practice the screw-stem F is designed to be strongenough to bear the thrust of the plow, or a suitable brace may be extended from the collar h to the rear portion of the guide A to receive the thrust. This, however, would readily suggest itself to any one versed in the art and does not require illus-j tration.

'In practice the operator rotates the screw F, which screws through the nuts G G. The thrust-nuts I I, rotating with the screwstem, bear against the collar h to raise or lower it with relation'to the plow-beam' If thehan- 'dle f is rotated to the left, the collar h is thrust downward and the braces H H force the standards 0 c apart at the bottomand cause the points 'of the'plo'wshare to rise, as lindicated in dotted lines in Fig. 4. 'When it is desired to force the plow into the ground,

the action of the screw is reversed and the bottoms of standards 1 c are drawn toward each other, thus causing the points of the shares to lower and enter the ground. The

operator can adjust the height of thewheel Q with relation to the plows O O by rotating the hand-wheel p". The screw P, acting upon the screw-nut j", forces the Bulky-wheel Q nearer to or farther from such nut, and so jraise's or lowers the wheel with relation to the plows to suit the slope of the ground upon which it isused. When the end of the fur row is reached, the operator raises the pawlhead it out of the notch'ct' bymeans of the grip-lever k" and turns the horses from him in the reverse direction. Thebeam D, being freed from its engagement with the guide A, revolves upon the stein of the screw F as the 'horses turn: .As soon as this rotation of the beam has carried the pawl-head k'beyond :the notch a, from which it is raised, the op- I erator releases the leverk" and the spring 15'' forces the pawl down upon the upper face of IIO the guide A, along which it slides until it reaches and enters the notch a upon the op jpositeside of the guide from that from which 'it was released, and so again locks the beam" upon the guide. The operator drives the team back along the furrow, opened when traveling in the reverse directiomthe hor'se whiclrtraveled upon the land smashin -0mg traveling in the furrow in makingthe' return trip; The same operation 'is 'repeated'when the 'end of the furrow is reached, the opera; tor thus alternately using the right and left hand plows and always throwingthe furrow in the same direction.

As the beam D re volves, the sprocket-wheel T revolves there with, and acting through the medium of the sprocket-chain t rotates the sprocket-wheel T, the seat-bow R, and seat r, while the sulky-wheel Q, brace-arm O, and sulky-arm J hold the screw-stem P firm to allow the seatbow and footbrace to revolve thereabout, thus causing the seat to automatically turn and the driver to always face the horses without any efiort for that purpose on his part.

When it is desired to change the width of the furrow which the plow will cut, the pawl M is released from the rack N and the lever K is then forced away from the operator, the pawl-head 70' beingin the notch a. The beam D is forced along the guide A away from the landside of the plow. When the plow is thus adjusted to cut the desired width of furrow, the pawl M is released and engages the rack N to hold the beam in the desired position upon the guide A. To cause the plow to take a narrow furrow, the pawl M is released from the rack, as before, and the lever K is drawn toward the operator, thus drawing the plow-beam over the landside of the plow which is in use, causing it to take a narrower furrow.

When it 'is desired to use the plow as a ditcher, the plows are placed side by side, as shown in Fig. 3, and are secured by the bolts 0 and 72.. These bolts are shown in Fig. 1. The plow thus throws the dirt right and left and forms a ditch. If desired, an additional set of plowshares may be attached by the bolts 0 and h so that the ditcher will be reversible the same as when arranged for sidehill plowing. The draft and guide-bearing plate E pulls against the circular guide A but the truss-beams B B being substantially in line with the plow-beam D the strain is practically upon the truss and not upon the guide. As the beam revolves, the lugs e" slide along the bottom of the guide and holds the beam firmly upon the track or guide.
