PLOW.

SPECIFICATION forming part of Letters Patent No. 544,994, dated August 20, 1895. v

Application tiled July 21, 1894. SerialNo. 518,191. (No model.)

To all whom it may concern:

Be it known that I, AUGUST PIRCH, a citizen of the United States, residing at Los Augeles, in the county of Los Angeles and State ot' California, have" invented new and useful Improvements in `General-Purpose Plows, of which the following is a specification.

rlhe object of my invention is to produce a device which will be more convenient to use, will be easy to operate, and will be more efficient than any device of this character heretofore produced, and one which, by simply rearranging its various parts, will be adapted to perform many kinds of work.

My invention consists of the features and the combination of parts hereinafter fully set forth and claimed.

The accompanying drawings illustrate my invention.

Figure l is a perspective side elevation of a device embodying my invention and arranged for side-hill plowing or for ditching. Fig. 2 is a frontelevation of the same arranged for ditching. Fig. 3 is a side elevation of my improved device adapted for use as a double sulky-plow. Fig. 4 is is a fragmental elevation of a plow, showing my improved reversible steel point removed from the plow. Fig. 5 is a perspective side elevation of my irnproved device arranged for use as asingle sulky-plow. Fig. 6 is a perspective fragmental side elevation of the plow shown in Fig. 5. Fig. 7 is a sectional View of my im proved revolving-disk moldboard and its journalspindle shown in Figs. 5 and 6. Fig. 8 is a front elevation of a curved colter, which is adapted for use with the revolving moldboard shown in Figs. 5, 6, and 7. Fig. 9`is a perspective view of a rotary pulverizing spider which is adapted to be arranged in place of the rotary disk shown in Figs. 5, 6, and 7 and to pulverize the soil as it is turned by the plow.

In diversied or general farming it becomes necessary to have tools which are suitable for use in performing different kinds of work. For instance, itis sometimes necessary to make ditches and at other times it isdesirable to have an implement which may be used advantageously in plowing sidehills, and it is also desirable that the farmer be provided with a double sulky-plow. It is also essential, in order toperform his work with facility` that he be provided with a single sulky-plow. It has heretofore been necessary p to provide a separate implement for each distinct class of work, no one implement being supporting beaml which is arranged upon suitable supporting-wheels B and B. Upon this beam the tongue C, by means of supporting-wheels c, is so arranged that the tongue may be shifted back and forth along the beam from side to side of the'implement. This tongue-supporting beam is provided with two vertical guide-posts a a', one arranged at each end of the tongue-supporting beam, andl along which the guides D and D', which are respectively secured to the beams ofthe right and left hand gangs of plow E and E', are arranged to slide.. These guides are each secured tothe front end ofthe beams of its respective gang, and by raising and lowering the guides along the guide-posts a ci the' points of the gangs E and E are raised to throw them out of the soil or lowered so 'they will be forced into the soil when the plow is drawn forward.

.As shown in Fig. l, the two plows e and e', which comprise the left-hand gang E', are secured together by means of brackets F and F', which are bolted to the beamsfandf, so that the movement of the beam ot' one of the plows will cause a corresponding movement of the beamof the other plow. The two plows e and e, which comprise the righthand gang E, have their beams G and G secured together by brackets g and g in like manner. These brackets are each provided with a series of holes g, whereby the brackets are made adjustable to bring the plows nearer together' or to throw themV farther apart, as may be desired. Each separate gang is provided with an actuating-leverlH and H', respectively, which are provided, respectively, with pawls h h', and arc-racks I IOC) I', which are respectively secured to the plow-beams G' andy".

In order to insure that the operation of raising and lowering the ends of the beams of the plows shall be entirely positive in action, I provide a peculiar arrangement of parts whereby the motion from the actuatinglever is transmitted by means of a chain and operates both to raise the beams and also to draw the end of the beams downward.

The device for raising and lowering the beams of each gang is the same in construction, and therefore I will describe the mechanism for raising the-gang E', shown in Figs. 1 and 2, and this description will serve as a description of both. This consists of the actvuating-leverI-I', which is pivoted to the plowbeam f', and two chains K and K', attached to the lever H', one chain, K, attached above the pivotal point I-I" of said lever, and the other, K', below the pivotal point thereof. The chain K passes forward and over a pulley 7a, which is journaled in theguide D' and thence downward, and is attached at its lower end to a suitable support L, which is secured upon axle M' of the wheel B'. The other chain K' passes forward and under a pulley 7c', which is also journaled in the guide D', and

, passes upward and is attached at its upper end to a suitable support L', which is attached to the upright guide-post of.' near the top thereof. Thus, when the lever H' is thrown forward it draws upon the chain K' and loosens the chain K, so that as the chain K operates to force the guide D' downward the chain K is loosened to allow the guide D to move downward along the guide-post a', thus to throw the points of the plows e e' into the soil; and when the lever is reversed and thrown toward the rear the chain K' operates to raise the guide D' and the chain K is loosened to allow such guide to be drawn upward, thus to raise the points of the plows c and e to cause them to run out of the soil.

I will now describe the mannerofsuppoiting the rear ends of the gangs E E'. Each gang is supported by a suitable supporting-wheel N N', respectively, which is provided with a shaft 'rt n', which is journaled in suitable guides 0 O' and is provided with a square shoulderrt. (Shown in Fig. 5, where thelocking-lever is omitted for clearness of illustration.) A suitable locking-lever P P' is arranged to fit upon this square shoulder n" to prevent the shaft 'n n' from rotating. The locking-lever P' is pivoted tothe plow-beam f by a pivotp and extends from such pivot toward the rear and is arranged to tit upon the square shouldern" and is provided with afor- Wardly-extending actuating-lever P"', which is arranged with its end within convenient reach of the operator when seated in the seat Q. By pressing down upon the end of thelever that portion of the lever which embraces the square shoulder is raised above such shoulder and allows the shaft to rotate as the wheel changes its direction of travel. A spiral spring R R is arranged, encircling the upper end of the stem n n', to force the lever P P' downward to cause it to engage the shoulder n" and to normally lock the wheel N N' against turning.

When it is desired to use the device shown in Fig. l as a side-hill plow, the gangs E and E' are alternately brought into use, thus to also throw the land always in the same direction-that is to say, when going in one direction the lever H is actuated to lower the ends of the beams of the plow e" and e" to cause such plows to enter the soil and the lever H' is actuated to elevate the ends of the beams of the plows e and e' to cause such plows to ride above the top of the ground, and upon the return trip the lever H is actuated to elevate the ends of the beams of the plows e" and 6' and the lever H' is actuated to lower the ends of the beams of the plows c and e', so that in returning the land is turned in the same direction as upon the for- Ward trip. When the end of a furrow is reached, the levers P and P' are operated to release the shanks n n' of their respective wheels N and N' in order to allow the shafts to turn as the plow is turned.

By reason of alternately using the right and the left hand gang of plows it becomes necessary to shift the clevis S into position to bring the draft into line with the plows which are in use. In order to provide couvenient means for accomplishing this I provide a transverse draft-rod T, which is arranged passing through the clevis-racks T', with one arm s encircling the draft-rod between the two beams of the gang E and its other arm s arranged encircling the draft-rod T between the two beams of the gang E'. To the tongue C, I secure a suitable'bracket c', which is arranged to engage and support the clevis S, and to the bracket g' of the plow 6"' I pivot an actuating-lever U, one end u of which is arranged to engage a suitable rack U and its other end tt' is arranged in a slot S' provided in the clevis S, so that by operating the lever U back and forth along the rack the clevis S and the tongue@ can be shifted back and forth across the plow to bring the draftclevis in line with whichever gang of plows is in use. The clevis-racks T' are pivoted to the plow beams to allow the beams tomove up and down with relation to the bar T.

In Fig. 2 I have shown the two plows e'" and e' connected by means of a ditchingpoint V, which is secured to the nose of each of such plows and forms a connection therebetween. A colter V' is arranged extending upward from such point in order to cut the soil to cause the furrows to open easily.

In Fig. 5 I have shown the plows e e' 8"' and the wheel B' removed from the device, the tongue-supporting beam A reduced in length, and to take the place of the wheel B' Iarrangeasupporting-wheelB"uponacranlcshaft b, which is journaled in suitable journals b', fixed to the rear end of the frame of IOO ros

I'ro

of the plow, and provide a crank b, rigidly fixed to the shaft b and connected, by means of a connecting-rod b", with the actuatinglever H, so that as the lever H is acuated to raise the guide D upward along the guidepost ct it also operates upon the crank-shaft ZJ to force the wheel B downward, thus to raise the plows out of the ground. When the operation of the lever is reversed to lower the guide D along the guide-post a, the crankshaft bis operated to raise the wheel B, thus to cause the plow-pointsv to enter the ground.

W, Fig. 5, represents my improved reversible steel point, which is provided with two series of bolt-holes w and w', so arranged that when the point is placed in position upon the plow with one side uppermost, the bolts will be arranged in one series of bolt-holes jw, and when the point is reversed to bring the other side uppermost the bolts will be arranged in the other series of bolt-holes w. This point is slightly twisted, as shown in Fig. 5, in order that the stem which is secured to the plow may conform to the curve of the moldboard, while the point will-lie flat in the furrow. I am aware that reversible points have heretofore'been made,l but they have been reversed by turning them end for end. My invention is to be distinguished from such points in that my point is simply turned to bring the side which was beneath upon the top, and the point thus becomes self-sharpening. In order to allow the point to be reversed it is necessary to extend the landside X forward andform a seat X for the point upon the upper face of the plow and between the landside and the share, as shown in Fig. 4. I provide the point WV with shoulders W', arranged one upon each side of the point, as shown in Fig. 6, so that' when the point is reversed it will tit between the share Yand the landside X, no matter which side of the point is uppermost.- t

I am aware that plows formed of' a rolling disk have been provided heretofore, but such plows simply cut a groove in the earth, and do not cutl a furrow square at the bottom, and consequently Va portion of the soil between the furrows is not stirred to the full depth to which it should be-that is to say, the disks gouge a series of grooves or channels, which 4are separated from each other by ridges of unstirred soil. I provide an improved device of this kind which combines the advantages ofthe ordinary plow with the superior features of the rolling moldboard.

My improvement consists of the plowshare Y, Fig. 5, a fixed moldboard 2, arranged above such share, a rolling moldboard 3, consisting of a disk arranged at the top of such fixed moldboard and having its lower portion arranged behind and below the top of such moldboard and journaled to the frame of the plow by a suitable arm 4. In order to prevent friction upon the bearing of the rolling moldboard I provide a ball-seat 5, Fig. 7, which is secured to the disk 3, and in this seat I arrange a ball 6. A shouldered sleeve '7 is arranged to receive a shouldered spindle 8, which is provided at its end with a seat adapted to seat upon the ball 6` and at its other end is passed through the supporting-arm et,

which is attached tothe plow and secured by means of a nut 9. The sleeve 7 is flanged at its outer end and is secured to the disk 3 by rivets or screws l0. Thus, when the bearing becomes worn the sleeve 7 can be removed from the disk 3, the spindle 8 can be removed from the sleeve, and a new spindle substituted with great facility. t I am aware that it has been proposed to provide a revolving disk at the top of a stationary moldboard; but, as heretofore employed, the lower portion ofthe disk has been arranged to receive the soil and to rotate toward the direction in which the soil is being turned. This causes great friction, for the reason that the moldboard is thus rotated in the direction opposite the movement of the soil which is being turned, and, therefore, instead of lightening the draft, itincreases the draft by reason ofthe increased friction which is thus produced.

In order to facilitate the turning of the soil I provide a gouge-shaped colter l2, which is rigidly secured to the landside of the plow and projects upward therefrom. This form is shown in Figs. 5, 6, and S, and is designed to be used when the rolling moldboard 8 shown in Figs. 5 and 6 is used. By attaching the colter to the landside it may be made to project upward onlya sufficient distance to cut through the top of the soil, and I thereby avoid the collection of weeds and other material which ordinarily gathers upon all colters except rolling colters. This gouge shape of the colter severs the land and causes it to be delivered against the rolling disk 3, so that the upper edge is rounded and holds its shape, and the disk is thereby enabled to readily turn the soil over without theland becoming broken. The disk at the rear of the vStationary moldboard rotates as the land is forced thereagainst, thus practically avoiding all friction, and since the friction upon the rear end of a fixed moldboard is always greater than at any other point the draft of the plow is materially reduced by this arrangement, while the bottom of the furrow is cnt square across and the soil is uniformly stirred in the same manner it is stirred by the ordinary plow. This construction is especially suitable for use upon my improved device, since it greatly reduces the draft, so that the increased weight of the additional gang of plows is not objectionable. i For convenience of illustration I have shown the ordinary form of moldboard on the plows shown in Figs. l, 2, and 3; but iu practice I prefer to use the form shown in Fig. 5.

In'Fig. 9 I have shown arotary spider con `sisting of the central body 13,provided with a series of radial arms 14E, projecting outward from ,the body and arranged to be rotatedby ICO tog

the land as it is turned over by the plow, and by this rotation to break up and disintegrate the soil. 15 represents suitable scrapers arranged to scrape the wheels B and B.

IVhen it is desired to use the plow as a double sulky-plow, the gang E is removed from the plow by slipping the end of the supporting-beam A off of the top of the upright guide-post a and by removing the draft-bar T from the clevis-brackets at the end of the beams fandf, whereby the plows e and e', the wheel B', and the guide-post a are disconnected from the remainder of the device. This removal of the Wheel B renders it necessary to provide a support for the gang E to serve in place of the wheel. To accomplish this I provide the crank-shaft b, having the Wheel B, journaled thereupon and arranged to be raised and lowered by the operation of the actuatinglever H, as hereinbefore described.

The clevis S is .attached to the gang E by means of a short draft-rod 16, and the beam A is removed from the bracket a and a shorter beam is substituted therefor. This shorter beam is not illustrated in detail, for the reason that the construction will be understood by those versed in the art, and no claim is made thereto.

When it is desired to use the device as a single sulky-plow, the bolts 17 and 18, Figs. 1 and 2, are removed, thus releasing the plow e" from the device, leaving the plow e to be used as a single sulky-plow.

18 represents suitable handles which may be secured to the rear end of the beams G andf when it is desired to guide the device by hand.

If it is desired to use the device as a double lister, the plow 6 may be removed from its beam G and may be secured to the beam f', to which the plow e is attached, and the plow e may be removed from its beamf and secured to the beam G', to which the plow e is secured, so that when thus arranged the device may be used as a double lister, in addition tothe other uses to which it may be applied. This arrangement of the plows is not illustrated, for the reason that itwill be readily understood by those versed in the art, and illustration thereof is not deemed necessary herein.
