SILAS E. BAILOR, OF TARKIO, MISSOURI.

CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 780,930, dated January 24:, 1905.

Application filed January 30, 1904. Serial 1%. 191,337.

To all whom it may concern.-

Be it known that I, SILAs E. BAILOR, a citizen of the United States, residing at Tarkio, in the county of Atchison and State of Missouri. have invented a new and useful Cultivator, of which the following is a specification.

This inventionrelates to improvements in cultivators, and has for its primary object to produce an agricultural implement of this character embodying a simple and inexpensive construction and so arranged that the direction of movement of "the machine and the raiswhereby the weight of the driver will be utilized in the elevation of the plows at either side of the machine or at both sides thereof, as the case may be.

Further objects are to decrease the weight and increase the stability of the frame structure and to equip the machine with novel guiding mechanism, including treadles disposed adjacent to the drivers seat for manipulation by the feet of the driver.

Subordinate to the objects stated are others which will appear duringthe course of the suc ceeding description of that form of my invention which for the purpose of this disclosure is illustrated in the accompanying drawings.

In said drawings, Figure 1 is plan view of a two-row cultivator embodying my invention. Fig. 2 is a side elevation thereof with one of the wheels removed. Fig. 3 is a vertical transverse section on the line 3 3 of Fig. 1. Fig. 4 is afront elevation. Fig. 5 is a detail perspective View showing a portion of the steering mechanism. Fig. 6.is a sectional view of one of the plow-beams, showing the manner of attachment of the rear plow-standards; and Fig. 7 is a similar View showing the mounting of the front standards. Fig. 8 is a view illustrating the arrangement of the plow-beams and the mechanism for raising and lowering the same.

Like characters of reference are employed to designate corresponding parts throughout 5 the several views.

The frame of the machine comprehends the axletree 1, from which extend forwardly the tongues 2, resting upon the tree 1 and supporting at a point some distancein advance of said tree a transverse frame-bar 3, preferably constructed of angle-iron. At the opposite ends of the axletree are secured brackets 4 for the reception of the vertical portions 5 of short crank-axles 6, which-pass through the hubs of the carrying-wheels 7 of the machine. These crank-axles are designed to swing upon vertical axes defined by the vertical portions 5 thereof for the purpose of changing the relation of the, carrying-wheels to the frame in order to properly guide the movements of the machine in a manner well understood in the art. Extending forwardly from the crank-axles are arms 8,secured thereto by brackets 9,as shown, and having their front ends connected by a rod 10, extending transversely across the machine.

The shifting of the connecting-rod 10 in a longitudinal direction will effect the swinging of the crank-axles on their vertical axes and will dispose the axes of the wheels at an angle to the line of draft for the purpose of facilitating the turning of the machine in one direc tion or the other.

A seat-post 17 of inverted-U shape is passed vertically through the axletree 1 to present and 23. The treadles 22 and 23 extend downwardly and rearwardly and are disposed to receive the feet of the driver, for whose accommodation a seat 25 is supported above and in rear of the axletree. When it is desired toguide the machine in one direction or the other, the proper treadle is depressed for the purpose of shifting the connecting-rod 10, and thereby swinging the crank-axles 6 in an obvious manner.

treadles and the rod 10 is effected through the medium of an oscillatory segment 10. fulcrumed upon a bracket 10, bolted to and sup- The connection between the IOO ported by the brace-bars 2 below the connecting-rod. The treadles are connected to the opposite ends of the segment 10 byfiexible pieces as, for instance, chains lO and the segment is in turn connected to the rod 10 by crossed pieces or chains 10, as clearly shown in Fig. 5. Obviously, however, other modes of connecting the segment and rod may be substituted for the crossed chains-for instance, a toothed engagement-constituting a rack-and-pinion connection.

To the under sides of the tongues 2 aresecured the arches 26 of the beam-supporting bar or frame 27. This bar is braced by inclined end braces 28, extending from the ends of the bar to the bearing-brackets 4, and by vertical braces 29, bolted at their upper ends to the frame-bar 3 and at their lower ends to spaced collars 30, encircling the beam-supporting bar midway of its ends and preferably connected by an integral connecting-piece 31. The forwardly-extending braces 24:, which have been described as being bolted to the lower ends of the seat-post 17, are bolted, as before stated, at their front ends to the vertical braces 29 at points adjacent to the collars 30. The beam-supporting bar 27 is thus rigidly associated in the frame structure, and the arches 26 thereof are designed for the accom modation of two rows of plants which are to be simultaneously cultivated by the implement.

From the beam-supporting bar 27 is swung a series of plow- beams 32, 33, 34, and These beams are disposed at opposite sides of the arches, and to prevent undue swinging movement thereof in a horizontal direction their front ends are preferably bifurcated, as shown in Fig. 1, and are apertured for the reception of the bar 27 To prevent the middle beams 33 and 3a from sliding laterally on the bar, a split retaining-collar 36 is secured upon the bar 27 between the terminal bifurcations of each beam. It will be understood that these several beams are designed for the support of the plows, cultivator-teeth, or other implements; but before describing the specific mounting of the latter Ishall first de- -scribe the novel mechanism which I have devised for facilitating the raising and lowering of the beams for the purpose of withdrawing them from the ground or of presenting them in their operative positions. The beams associated with each of the arches 26 constitute a gang designed to be raised and lowered by a yoke- shaped lever 37 or 38, pivoted to the frame-bar 3, as shown in Fig. 3, and provided with a spring-latch 39, disposed to engage a segmental rack 4:0 for the purpose of retaining the lever in its adjusted positions. As this machine is designed for use as a doublerow cultivator, the beam-supporting bar is formed with two arches, the plows are divided into two'gangs, and two levers 37 and 38, one

therefore utilized. To each of the lovers 37 and 38 are connected the upper ends of a pair of lifting-rods ll and 42, disposed vertically and passed through openings in the horizontally-disposed upper ends of posts s 3, upstanding from and secured to the beams of the gang controlled by the lever. Each of these rods is encircled by a stout spiral spring 44, bearing at one end against the post-it3 and at its opposite end against a spring-cap +15, secured to the rod adjacent to its upper end, or, if desired, the cap maybe omitted and the spring disposed to bear directly against the lever. Since the levers are held rigidly by the engagement of their latches with the racks 40, the springs 44, bearing upon the posts 43, will urge the beams toward the ground, but will yield to permit the raising of the beam in case the plows should encounter an unusual obstruction. Upon the lower extremity of each of the rods 42 is screwed a nut 46, and between this nut and the under side of the horizontal portion of the post 43 is disposed a buffer-spring 47, encircling the rod &2. The purpose of these buffer-springs -17 is to permit the smooth working of the parts when the levers are operated to lift the beams, as it will be observed that the first movement of the lever will be taken up by the compression of the spring a7, and the beam will then be elevated after the inertia of the lever has been overcome.

We now come to consider an important feature of the invention, residing in a novel construetion andarrangement of parts, whereby the weight of the driver is utilized to assist in the raising of either gang of plows independently of the other gang or in unison therewith, as desired. The seat is supported upon the rear end. of aseat-beam 18, pivotally supported at a point intermediate of its ends upon the upper or closed end of the seat-post 17, the transverse bar &9 of the latter being rounded and fitted into ears 50, depending from the beam 48. The beam 48 is disposed longitudinally of the machine and is provided at its front end with a pair of pendent links 51, between the lower ends of which is medially pivoted a transverse yoke 52, having its opposite ends extended upwardly to engage brace- bars 53 and 54, which serve to brace the opposite side portions of each of the lovers 37 and 38. It will thus appear that the weight of the driver will tend to depress the rear end of the seat-beam a8, thereby elevating the yoke 52, secured to the front end of the beam, and exerting considerable force in an upward direction upon the levers 37 and 38. Therefore upon the release of these levers from the racks the weight of the rider will be utilized to assist in the elevation of the plowbeams, and if this weight is more than counterbalanced by the weight of the parts to be moved it is simply necessary for the operator for each gang of plows or pair of beams, are i to pull upwardly on the handles of the levers for the purpose of effectually lifting the plows from the ground. Obviously if it is desired toelevate one only of the gangs of plows this may be accomplished with equal facility, as the yoke is mounted to rock upon a central axis to accommodate the independent movement of one of the plows, and the weight of the rider will therefore be utilized in raising oted intermediate of its ends upon a stud 56,,

projecting from one side of a standard-supporting bracket 57, ad justably retained against one side of the beam by a strap 58, clamped against the opposite side of the beam by nuts 59, screwed upon bolts 60, extending from the bracket 57. At the upper end of the bracket 57 is disposed an angular socket 61 for the reception of the upper end of the standard 55, which latter is retained against movement by a wooden or other frangible break-pin 62. This pin is of suflicient strength'to sustain the usual strains brought to bear upon the lower end of the standard by the movement of the plow through the earth, but is designed to break under unusual strains in order to pre vent injury-to the standard or its mounting. By this arrangement the front standard is offset from one side of the beam, and in order to secure a proper lateral separation of the two plows carried by each beam the front standard 63 is offset by a bracket 64 from the opposite side of the deflected rear end 65 of the beam. The bracket 64 is bolted to the beam, as shown in Fig. 7, and the mounting of the standard thereon is similar to the mounting of the rear standard on the bracket 56.

A simple draft-equalizing device is shown applied to the cultivator. This device comprehends a middle swingletree 66, to which is connected a draft-chain 67, passed under the pulley 68 (mounted on the bar 27 between the collars 30) and around a pulley 69' and terminally secured to a bolt 70, passed through the vertical braces 29. The pulley 69 is mounted in a frame 71, in which is mounted a second pulley 72, having its axis at right angles to the pulley 69. Around the pulley.7 2 is passed a short length of chain 73, the ends of which are passed in opposite directions around pulleys 7 4L and upon' the front of the axletree and are attached to to the draft-chains, as shown in Fig. 1. By this arrangement the draft is equalized.

It is thought that from the foregoing the construction and operation of my cultivator will be clearly apparent; but while the illustrated embodiment of the invention is believed at this time to be preferable I do not wish to limit myself to the structural details defined, as, on the contrary, I reserve the right to effect such changes, modifications, and variations ofthe illustrated structure as are fairly embraced within the scope of the protection prayed.
