PLOW.

SPECIFICATION forming part of Letters Patent No. 536,306, dated March 26, 1895.

Application filed August 3, 18 94- To all whom it may concern..-

Be it known that I, MARINUS WEBER, a citizen of the Republic of Switzerland, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Plows, of which the following is a full and exact description.

My invention relates to gang plowsin which a number or gang of shares is employed. It has also reference to single plows which are provided with one share only. Both types of my improved plow, the single shared one as well as the gang plow can also be used as scarifiers and both can further be arranged for the purpose of sowing sugar beets, potatoes and the like.

Heretofore the share supporting frame in gang plows was either stationary and then unmovable or could be raised and lowered only. Further, in steam plows employed so far, two gangs of shares were generally provided if it was desired to plow on the return way. Plows with one gang of shares could be used as scarifiers in either direction only when the single shares on a rigid frame were each adjusted accordingly.

In my improved plows the above described deficiencies are overcome.

My gang plow requires only one gang of shares for plowing to and fro. This is accomplised notably .by means of a share supporting frame, which is movable in the horizontal plane in which itis supported. This frame is pivoted to a stationary frame, and for convenience sake the stationary frame will be called the main frame while the frame moving in the horizontal plane in which it is supported will be referred to shortly as the movable frame. To the movable frame are attached the two principal wheels. There is further a platform on the front .of the movable frame, preferably cast on integral therewith. This platform is half circular in shape and provided with teeth for the purpose of operating the movable frame as will be fully described farther down.

The shares inmy improved plows areof novel construction, and their plates can be turned or shifted to the right or left of the share stocks without lifting the shares; so.

attendant.

that right or left-hand furrows can be turned,

$eria1No.,519, 395. (No model.)

provided the share plates are arranged accordingly. By means of the movable frame is further accomplished that all the shares can be used simultaneously for plowing to and fro and none need to be idle while plowing in either direction.

My invention has further reference to improvements in a lifting and lowering device for the regulation of the depth of the furrows, to improvements in the steering mechanism, to a novel method of equalizing the movement of the shares in the ground, and to devices for raising or lowering each wheel independently.

The plows are illustrated in the accom pan ying drawings, in which Figure 1 is a side elevation of the gang plow with the steering wheel in the rear and provided in this instance with five shares. Fig. 2 is a plan view of Fig. 1 without the seat of the attendant. Fig. 3 is a cross section of the movable frame. Fig. 4 is a front elevation of Fig. 1. Fig. 5 represents on a larger scale the steering wheel with attachments used when in the rear of the plow. Fig. 6 shows on a larger scale a share with connection on the movable frame, and its position when raised. Fig. 7 is arear elevation of Fig. 6, showing also a device for hanging up the share and the position of the share plate when shifted to the right. Fig. 8 is a side elevation of a share in the position necessary for sowing beets, duo. Fig. 9 is a plan or top view of Fig. 8. Fig. 10 is a side elevation of a single plow, and shows the position of the share when raised. Fig. 11 is a plan view of Fig. 10 without the seat of the Fig. 12 is a front elevation of Fig. 10 without the seat of the attendant. Fig. 13 is a side elevation'of the gang plow with the steering wheel in front, and Fig. 14 is a plan view of Fig. 13. I

Similar letters of reference indicate corresponding parts.

The gang plow is made in two constructions. For uneven ground it is desirable to have the steering Wheel inthe rear and for even ground the same is in the front. The latter construction simplifies the whole plow a greatdeal.

The gang plow with the steering wheel in the rear will be described first. The main frame of the same consists of two parallel bars A, A, Figs. 1 and 2, cast, or madeof wrought iron or of steel. It runs under the movable frame where it is pivoted to the same, so that it is principally carried by the two inclined wheels attached to the movable frame. The bars A, A rise rectangularly at a to a, Fig. 1. From there they extend rectangularl y rearward and at their ends they are again rectangularly bent down ward. These downward portions are connected by three parallel cross bars, A A A riveted or bolted thereon. A number of other cross bars and bridges further help to hold the main bars A, A in a stationary position, but nearly all of these cross bars and bridges have other functions besides fixing the main frame.

Between bars A A A, is located a screw box in which runs a rod provided with a thread and leading to a frame which supports the steering wheel. Thus the steering wheel helps to carry the main frame, most of the weight of the plow being between the three wheels.

Each of the principal bars of the main frame is divided in the front at a Fig. 1. The lower portions, A act as a support for two loose cross bars 0, O which pertain to the draft and to the device for equalizing the movement of the shares in the ground. The upper portions A, are bent and rise then straight up. Above the bend is a segment integral therewith which is provided with teeth and has at a a bar A extending straight down to a where it turns backward under an angle and connects with the main bar. This backward bent portion of bar A forms the support for the foot board of the attendant. The principal bars of the main frame are further connected by the cross bridges A", A A, Fig. 2. These cross bridges are preferably fastened under the principal bars. To the cross bridges A A is pivoted the movable frame. The pivots are exactly in the center of these bridges. Above the segment are two connecting bars A A The bar A extends over the principal bars A, A and is bent up so as to form a rein bridge. By these cross bars and bridges the main frame is very substantially fixed and possesses great strength and durability.

The movable frame consists of two parallel long bars B, B and two parallel short bars B B The latter are also parallel with the main bars A, A of the main frame. The four bars are pivoted together by upright standing rods E, E, E E as illustrated in Figs. 1 and 2. The two long bars are pivoted in the center to the main frame, bar B to the crossbridge A and bar B to the cross bridge A. On these pivots the movable frame is shifted in its own horizontal plane and the wheels and everything else attached to it change position accordingly. If the movable frame is now shifted so that it is under a right angle to the main frame, then the four bars constituting the frame form an oblong. If the frame is however shifted into any other position, for instance, as shown in Fig. 2, then the four bars form a rhomboid.

On the long front bar B of the movable frame is the platform B preferably cast on integral therewith. The platform is provided with teeth which are engaged by a cog-wheel M. The shaft of this cog-wheel goes straight up and passes through a side flange A of the segment A and forms farther up a crank handle. If this handle is turned then the cogwheel engages the teeth of the platform moving the same and thereby shifting the whole movable frame in its own horizontal plane, consequently moving the wheels, shares and everything else attached to it. The frame can be shifted in this way until its bar B touches the upright portion of a main bar of the main frame. A platform arrester P is on the main bar Aof the main frame and on the side bridge A, Fig. 1. It is operated by the foot of the attendant simply by raising and lowering a bent lever which is pushed between the teeth of the cog-wheel M after the movable frame is adjusted. The position of the movable frame as shown in Fig. 2 is the one generally used in plowing and shows that the furrow slices in this instance are turned to the right. At the end of the land the plow has to be turned round and the movable frame shifted so that it is under the same angle but in the opposite direction. Now the share plates are turned to the other side of the share stocks when the furrow slices will be on the left then harmonizing with the furrow slices made already.

The short bars B 13 are further provided with three holes each. Through the center holes pass the rods E E and through the side holes in bar B pass the rods E, F. while through bar B pass rods E E". To the lower end of the rods E, E is attached firmly or cast on astrong piece P, and a similar piece P is attached to or cast on the lower ends of rods E E, Figs. 1 and 3. In the pieces P, P are the axles for the two principal wheels 0, C. The axles are under a slight angle downward. Consequently the wheels are inclined and closer together on the soil.

The four rods pivoting the movable frame extend straight up, and are lessened in diameter so as to form shoulders and to receive the cross bars F and F. A little above these bars are two similar bars F F The rods E and E are a little longer on top than E, E for the purpose of receiving a long cross bar F, which is parallel with bar B of the movable frame. The frame work formed by these rods moves with the movable frame and serves for fastening the various attachments of the same.

The movable frame carries the shares. The ends of the share-beams are pivoted in ears or lugs H, H H H H These ears or lugs are on the front bar 8 of the movable frame, (Figs. 1, 2 and 3.) The frame has correspondsponding with the lugs in bar B five guidings' for the shares. They are necessary because the shares would move or swing sidewise if supported only in the lugs HH These guidings G, Fig. 3 consist each of two square bars of iron having suflicient space between them for the upward and downward movement of the share stock. The bars are provided with shoulders at the top and bottom. All the guidings have on their shoulders pins in the center whose lower pin goes through the frame bar B and the pin on the top goes through the connecting bar F. In this way they are securely fastened without needing screws and nuts. The center guiding G0 however, must be especially well fastened, because it runs through the center of the frame bar B and through cross bridge A where frame bar B turns. Therefore it is fastened by means of a screw and nut after passing through E. On the guiding G0 is further cast, before it passes F, a shoulder of the shape shown in Fig. 1, and for a purpose which will be described farther down. As described, the rods E, E are connected by cross bars F, and F These cross bars are provided with five holes each. Through the center holes passes a rod E to which is attached a crank handleon the top. Rod E is providedwith a screw thread. The bottom of this rod is turned down forming a shoulder and pin and the pin rests in a hole in piece P. The shoulder keeps the pin in position, but allows the turning of the rod around its own axis. By this motion the attendant is able to raise or lower this wheel independently of the other by simply turning the crank handle. To accomplish this a screw box K is provided in which the screw thread of the rod E runs. The rods E, E are loose in their holes in bars F, F and can slide up and down, while the rod E has a shoulder below a cross bar F which connects the rods E E so thatit cannot move upward when its crank handle is turned. Consequently when the crank handleis turned then the screw thread moves in the screw box, for

instance, upward and carries with it the side rods E E and the wheel 0 connected thereto by the cast piece P. The-rod E is a little longer than the rod E -It is provided with a notch or indentation for the purpose of receiving the handle. The same can be turned over vertically and then arrests the motion when the wheel is in the desired position. The other wheel 0 can likewise be raised and lowered independently.

The shares are of novel construction. The

The lugs are cast in S S and cross piece S hook when not in use.

share plates can befturned or shifted to the right or left of the share stock without lifting the share, Figs. 6 and 7. The shifting is necessary for plowing on the return way in order to get the furrow slices in the desired side. The share frame consists of beam S, stocks Thelatter is curved exactly like the share plate to allow the same to pass under it. The lower portion of stock S forms the colter. In its rear end at s fits loosely the pin forming the point of the share plate. Cross piece S is provided with part S on which a movable T piece S is fastened. The T piece ends fit in holes in the share plate. The T piece turns to the left or right under the beam S. If the'share plate is on the left side of the share stock, Fig. 6, then the T piece is in the right hole. The front end of beam S is pivoted to the lug H so that the share can be raised when out of gear. Beam S has further a piece S near the front end and extending downward. This piece has three holes. A small'pulley is fastened in one of the holes. Over the pulley runs a wire rope which connects with the draft and"v when the share meets with obstacles in the ground then it jumps. Fig. 7 further shows how the share can be lifted and hung up in a The hook is pivoted to one bar of the guide and moves on the pivot. Ordinarily the hook is simply moved off from the beam, and then the share drops, but when it is desirable to'let the share down gently on roughor stony ground then the share is lifted until the beam S strikes the top end of the hook and raises the same (Fig.

7). The share is then let down and will pass the stationary position of the hook before the same returns.

The share plates can be taken out very easily when repairs shall be made or an exchange is required. The broad rear portion of the share has three supporting arms Fig. 7, which center below the middle arm. The extension is bent and bolted to theend of the stock S Fig. 7. When this bolt is taken out the share can be taken out. The lower portion of S is curved for the purpose of preventing the aggregation of the thrown up earth beforethe bolt which would give unnecessary resistance to overcome. The beam S is further provided at its utmost rear end with a weight cast thereon for the purpose of pressing the share down. Seen from the center line of the share stock Fig. 9 the share plate is shaped the same way on either side for enabling the shifting to the right or left and getting the furrow slices to either side. The front of the share plate near the pin is shallow, Fig. 7.

In the plow preferably used on uneven ground the steering wheel D, Fig. 4, is in the rear and is supported between the two main bars of the main frame. A steering wheel supporting rod D runs in a screw box K 10- cated between the main bars of the main frame and supported by cross bars A A and A Figs. 1 and 5. The rod D is provided with a screw thread which moves in the screw box. The rod is riveted or forged to a fork shaped frame L, L in which the wheel turns. To the bar L of the forked shaped frame is bolted a rod D which is twice rectangularly bent so as to connect with the top of rod D. A square shouldered bolt fixes D and D permanently. On rod D slides a bar D Figs. 2 and 5. The bar D rests on the rectangular piece D Figs. 2 and 5 which is fixed to the main bar A of the main frame. The bar D runs from the attachments of the steering wheel outside and along the main frame bar A to the front, coming gradually nearer to the bar A as is seen in Fig. 2. About half way bar D is provided with a movable joint which rests on a bar attached to the main frame. From the joint J it runs down rectangnlarly like and alongside of the vertical part of the bar A of the main frame, about in the middle, Fig. 1. It is connected thereto by a pivot. At the lower end of bar D is a similar joint J and the rod then runs to the front where a like joint .l is provided. From this point the rod turns straight up and a little above the last mentioned joint it is pivoted to the stag A of the segment A. The rod forms a straight handle at the top which can be moved forward and backward and it is plainly understood that by means of the bar D provided with the described joints and pivoted as described the steering wheel can be directed to the right or left as desired. The handle is provided with a locking device which fits into the teeth of the segment A and looks the same when the steering wheel is adjusted.

The device for equalizing the movement of the shares in the ground consists principally of a wire rope R running over the rollers which are pivoted between bars 0, 0. These bars are bolted together at their ends and in the center so as to leave space between them for the free movement of the rollers. Four rollers are provided between the bars. The rope runs beneath the movable and main frames. The ends of the rope R are fixed to two small downwardly curved extensions 12 b on the short bars B B of the movable frame. From 12 the rope runs over a roller R fastened in one of the three holes of the downward piece S of the share beam S and runs through to the front to roller R which is one of the rollers between the twoloose bars 0, 0. After passing R the rope goes back to roller R which is in a hole of S of the next share. The rope then runs forward to roller R and so on to R to the third share to R between 0, O to R on the fourth share, to R between 0, O to R on the fifth share and b where it ends. This mechanism is operated by the draft of the horses. The center bolt of O, O has a bar extending forward. On this bar is the axle to receive the lines for the draft. If one share now meets an obstruction in the ground then by means of this rope Rtbe resistance is transformed to all the shares and allows that this share meeting the obstruction stops and moves upward and releases itself, that is, it jumps.

The seat is supported by the rod which is cast on the lug 1-1 This lug is longer than the other lugs. About in the middle of this rod is attached a box like frame which carries the seat. Between this frame and the lug H is a strong spiral spring for easing the seat.

The device for raising or lowering the whole frame work for regulating the depth of the furrow consists of a continuous chain running over cog-wheels. Behind the seat is a special frame which is situated between the central guiding Ga and the seat supporting rod. This frame supports a shaft which forms a crank handle on the top. Outhe shaft and between this frame are two cog-wheels K, K over which the continuous chain runs. The shaft is square where it runs through the cog-wheels in order to hold them securely and it is round where it runs through the frame. It is shouldered before entering the top bar of the frame. The cog-wheels are separated by an intermediate piece like a heavy washer. The chain runs from the cog-wheel K to the cog-wheel K which is on the steering wheel supporting rod D. It returns then on the cog-wheel K and goes then to cog-wheel K which is on the rod E Figs. 1 and 2. Then the chain goes to the cogwheel K on rod E If the crank handle is now turned then the continuous chain runs over all the cog-wheels and turns them by their motion. The screw boxes move up or down on the threads of the rod, as the case may be, and then lower or raise the whole frame work supporting the shares accordingly, in this way regulating the depth of the furrow. It is plainly seen that the shares can be raised above the ground if it is desired to do so. In order to raise the whole frame work it is necessary that the screw thread on rod D is cut in the opposite direction of the threads on E, E

The wheels attached to the movable frame are slightly inclined as described for the purpose of keeping them on unplowed ground. This is further accomplished in this construction by having the wheels at little before the shares and is always the case when all the shares are in operation. It is however plainly understood that, if necessary, any number of shares can he lifted and hung up, so that, if desired only one share, the middle one, is used. When the outside shares are out of gear then the wheel next to the furrows already made runs in a furrow and thus makes the plow uneven. To prevent this the mechanism described already for raising or lowering one wheel independently is operated. The wheel in the furrow is simply lowered until the plow is level. Heretofore certain plows had wheels of different diameter which was inconvenient under circumstances other than the ones just described.

For plowing on relatively even ground the gang plow is greatly simplified and the steering wheel D is in the front. Fig. 13 shows a ICC side elevation of such a gang plow and Fig. 14

is a plan view of Fig. 13. The movable frame in this plow is of different construction. The side bars of the movable frame B B are elongated as shown in Fig. 14 and the wheels 0 C are attached thereto in the rear portion of the elongated bars. By this is accomplished that the principal weight'of the plow is in front of these two wheels and consequently the steering wheel has to be on the front so that the weight rests on the three wheels. The steering wheel is now regulated by the draft and the whole mechanism-for operating the same is dispensed with. Further, the device for raising and lowering the whole share supporting frame work is not necessary here. Only the devices for raising and lowering each wheel independently remain. The main frame bars A, A are farther apart than in the first described construction. They end a little behind cross bridge A and branch out in the front as illustrated in Fig. 13. The steering wheel rests in a forked shaped frame similar to the one shown in Fig. 5. To this frame is attached a front standard which is provided with a thread. A wheel V runs on this thread and by means of the same. the steering wheel can be raised andlowered independently. T which is attached as illustrated in Fig. 13. The block runs loose on the front standard and between its top and bottom part is supported on the front standard a double, perforated segment to which is bolted a shackle lifting lever U which is locked to a pin in two perforations of the segment. From the lever U a shackle rod U goes down to the draft. This shackle lever device regulates partly the firmness with which the shares enter into the ground. In the block T runs a threaded shaft which is pivoted to the ends of the main frame, Fig. 14 and on it the steering wheel can be moved backward and forward, to suit the movement of the shares in the ground. The shaft extends over the main bar A and to it outside of the bar is attached a wheel by means of which the block T is moved to the right or left, thereby moving the steering wheel and all its attachments in the same. direction. This is necessary when one of the side shares is out of gear. The resistance met then by the other shares in the ground will act unevenly on the draft and to prevent this the steering wheel with its attachments is moved into the center line of the shares in the ground. To the top end of the front standard is firmly attached a lever U which extends rearward so that the attendant can reach it from the seat and adjust by it any slight deviation of the steering wheel. The motion of the steering wheel however is principally regulated by the draft. The device forequalizing the movement of the shares in the ground is the same as already described. The wheels attached to the movable frame are straight in this construction. The screw boxes on the rods E E are bolted between the cross bars F, F and The wheel Vcarries the block F and F respectively. The cross bars F, F extend downward, Fig. 13, after leaving the rods E, E and are securely fastened to the main front bar B of the movable frame thus acting as a substantial support.

An uneven number of shares is shown and described, but by means of the movable frame it is just as easily possible to have an even number of shares all of which can be worked at once. The difference in the construction is in the attachmentof the shares to the movable frame. In the described constructions a share was fastened to the front center pin of the movable frame and in the construction for an even number of shares the one in the center pin is omitted and the even number of shares is arranged at even distance accordingly.

The gang plow illustrated in Figs. 13 and 14 may be provided with any even or uneven number of shares and any desired number can be used simultaneously.

In the gang plow illustrated principally in Figs. 1, 2 and 4 any number of shares may be provided but if an even number is there then only an even number can be used simultaneously because the resistance of the ground would be uneven on the plow.

It is evident that steam power can be used instead of horses.

A single shared plow has also been constructed. The sameis illustrated in Figs. 10,

Y11 and 12, and contains my improved share whose plate can be turned to the right or left of the share stock without lifting the share- The wheels of the single shared plow are;

turned on a crank axle. This axle is provided with a lever, Figs. 10 and 11. The lever is bent near the crank axle, Fig. 11. On the axle is fastened the share supporting frame T which isstrengthened by a cross bar Q as shown in Fig. 11. To the frame is attached the segment which regulates the position of the share and thus the depth ofthe furrow. The share can be lifted and is supported by a locking. arrangement. The seat is supported by a spring bolted to the frame and shaft. Itturns up and down again, Fig. 10, so as to form the basis for the foot board U To the beam of the share are attached in the front two pieces, Fig. 10, fittin g close to the frame. They are fitted to a cross piece which is pivoted to the frame. This arrangement allows the share to move up and down. From the frame runs down a piece Z which is connected to piece S of the share beam by a rod to which the draft arrangement is attached. For keeping IID piece fits. The hole is near the outside of the share plate so that the share plate is in a horizontal position. In this way the narrow furrow is obtained and if a very narrow one is desired then the share is simply raised a little so that practically speaking the colter alone cuts the ground. The beets, for instance, are then put into the furrow and in returning the plow shares must run between the furrows to hill up the earth so as to cover the beets.
