SPECIFICATION forming part of Letters Patent No. 508,028, dated November '7, 1893.

Application nea March 2. 1893.

vin which similar figures and letters of reference indicate corresponding parts in all the views.

lFigure 1 is a'plan view of the cultivator. Fig. 2 is a longitudinal vertical section taken practically on the line 2-2 of Fig. 1. Fig. 3 is a front elevation of the cultivator, the pole being shown in section, the section being taken on the line 3-3 of Fig. 1; and Fig. 4is a transverse vertical section taken practically on the line 4-4 of Fig. 1.

In carrying out the invention the frame of themachine may be said to consist of two beams A and B, forward arches 10 and 1l, rear arches 12 and 13, front and rear guide plates 14 and 15, receiving the crown orbody of the arches, and a socket 16, carried by the rear plate and adapted to receive the rear end of the tongue or pole V17. The beams A and B, are arranged opposite each other; they are horizontally located, andthey are made to converge at their forward ends and diverge at their rear ends. As each beam is of like construction, and furthermore, as each beam carries disk oultivators in the same manner, the detailed description will be conined to one of them. Each beam consists of two parallel and spaced bars 18 and 19, the extremities of both of the bars being placed atan angle to the body, the bodyof the beams occupying a diagonal positionwith respect to the extremities, the extremities being made straight; and the forward extremities are designated as a, while the rear extremities are designated as a. The bars 18 and 19, are connected near the forward and rear ends of their body portions by means of cross bars sena No. 464,379. (No model.)

20, which cross bars are` provided with an outwardly extending central eye 2l. A boxing C, is located at the rear of the beam and a boxing C', is located at the front thereof. The rear boxing consists of a casing, comprising as is shown in Fig. 4, a body portion 22, which is hollow and provided ateach side with a recess 23, and an upper socket 24, located transversely upon the body and a lower transverse socket 25, together with a rear socket 26, shown best in Figs. 1 and 2, which socket 26, is provided with a circular interior, while the remaining sockets, and likewise the interior of the body are made more or less rectangular. The eye 21 of the rear cross bar 20 of the beam is made longer than the interior of the body of the boxing C at the front thereof, and is pivotally held therein through the medium of a pin 27; and the rear end portions a of the bars ofthe beams are made to enter the side recesses 23 in the body. Thus the beam may have more or less play in the boxing.

The forward boxing C', is identical with that shown and described with reference to the rear boxing C, with the exception that its outer or front socket, which is the equivalent of the rear socket 26 of the rear boxing, has a rectangular or polygonal interior and is designated as 26a; and the forward end of the beam is connected with the forward boxing in like manner as the rear end is attached to the rearboxing.` Each beam is provided with a series of slides D, which are adapted to be moved longitudinally uponrthe side barsof the beam, or the body portion thereof. The construction of a slide is best shown in Fig. 4, in which it will be observed thatthe slide consists of an upperl bar 29, a lower bar 30, and an upright bar 3l connecting the upper and lower bars back of the inner ends of the latter, the outer end portions of the upper and lower bars being connected by stand. ards 32, which standards extend somewhat above the Vupper bar andare provided with bearings, the standards being placed at suitable intervals apart and being connected at their outer ends. In the standards of each slide a worm 33, is journaled, and as shown in Fig. 1, one end of the worm is squared to receive a wrench, as illustrated at 3 4 in the said figure. One side bar of a beam passes between the upper and lower bars 29 and 30 of a socket, and in engagement with the inner upright bar 31, while the other and outer side bar of the beam passes through openin gs 35, produced in the standards; and after the slides have been properly adjusted upon the beams they are held in their adjusted' position by set screws 36, which are passed up throughthe connecting bars ofthe slide standards to an engagement with the outer bar of the beam,as is likewise best shown in Fig.4; but any equivalent of the said fastening device Inay be employed if in practice it is found desirable.

It will be observed that by reason of the peculiar construction of the slides a central open space 37, is obtained; and each standard is adapted to receive a shank 38 of a cultivator, and said shank which is preferably round, is carried upward through the slide,

being loosely mountedtherein; and through this central space 37 the upper end l of the i shank extendsa suitable distance above the i uppenface oftheI slide. Each shankislpractieally angular or Lshaped,ras is clearly sl1own\inI`ig.-4, the vertical member-being1u mounted in a slide, While the horizontal mein'- ber extends inwardly beneath the beam and is adaptedto carry a disk cultivator'E. The

shank ofa disk cultivator is adapted for vertical adjustment in its slide, and likewise is adapted to be turned readily therenso as to` cause the disk `cultivatorto entertlle ground -to a greater or less degree, and in order to give itany desired inclination beneath the beam. Thevertical adjustment is provided for by placing a collar 39 upon the vertical member of the shank within the opening 37 of its slide,.the collar being providedwith a` suit- `able set screw. Thus by lowering theset screw the shank may be raised or loweredf and by tighteningit the shank `may `be held in 4au adjusted position, and as the collar is located within the slide and loosely placed therein the shank may be turned Without the collar oiering any resistance.

A rotary movement is imparted to the cul` tivator shank by securing upon the upper endiofthe shank a mutilated or segmental gear 40, which is preferably secured thereon by means of a set screw, as shown in Figrl,

and this `gear meshes `with the Worm carried by the slide in whichthe shankis` located. Therefore, it will be observed that by manipnlating the worm 33 the shank may be turned in whatever direction it is desired to place the disk E, which fit carries.

The cultivator disk E, is of peculiar con-i mounted loosely upon the horizontal member of a cultivator shank; and the cultivator is held upon the shank either by means ot a nut, as shown in the drawings, or by screwing a cap on the hub over the end of the shank, in which latter event all dust or dirt is excluded from the axle of the cultivator.

Any desired number of cultivators may be placed upon a beam, and the beams are connected at the front by the arches 10 and 11 and at the rear by the arches 12 and 13. The arches at the front and rear are arranged one above the other. The arch 12, which is the upper arch, has its members carried downward and outward in opposite directions and thence horizontally into the upper socket 24 of the rear boxing C, while the members of the `lower arch 13, are carried in the same dircction and made to euterthe `lower sockets 25 of the rear boxings. Each arch isimade in two sections, asshown in Fig.` 4, one section being connected with the rearboxingof each beam, while the upper ends of the arch `sections are made toenter sockets produced in the upper and lower portions of-the guide platesl; the said sockets `,being ldesiguated in the drawingsas 15. Therefore, when two beams have been coupled togetheriby the rear arches the space between Ithem may be enlarged or `lessened by adjustingthe arch sections in their sockets;` and afterthe adjustmenthas been made the arch sectionsare held firmly in their sockets by means-0t set screws 43, or the equivalent thereof,` asshown in Fig. 3.

The front portions of the beams-A and B, are connected in like manner as the rearportions by meansof the front arches'lO and 11, whichare similarly disposed to the rear arches, the sockets in the front guide plate `14, how ever, being designated in the drawings as 14"'. The guide plates are `connected by brace rods 44, which are Apassedfrom plate to plate, en tering said plates betweenitheir upper and lower sockets, the guide rods being provided with suitable lock and check nuts. Ordinarily two guide rods are employed, one being located at each side of the center of the plate.

The sockets of the frontand rear plates face each other, as shown in Fig. 2 g andiupon the front plate at its centeri ears 45, are located, and between said earsf the pole or tongue 17 of the machine ispivoted, while the `rear or butt end of the pole or: tongue is-made to enter the box or socket 16, secured to lthe centraiportionfof the rear arch guideplate 15 uponthe forward face of` saidplate; and as shown particularly in Figs. 2 and 4, this box, which is open at its front, extends some dis tance `upward beyond the said plate 15; there fore, the tongue 17 hasifree and guided movement inthe box 16, which is of a width just sufficient tofreely admit the tongue or pole; and whenlthe machine is drawn over undu latingfor rough ground the rear end ofthe pole will ascend or descend, moving freely in IOO its box 16, and therefore there will be no unnecessary strain upon the team, the machine accommodating itself to the inequalities of the ground while the pole or tongue will accommodate itself to the motion of the team. It is necessary, however, in turning corners and on some occasions, to hold the tongue or pole in a rigid position, and this is preferably accomplished by mounting upon the top of the box 16 a lever 46, and connecting that lever with the pole or tongue near its rear end by an arched link 47,-whereby when the lever is pressed downward and rearward until the link has passed its center, the pole or tongue will be locked firmly in the box, and it may be as conveniently released by throw` ing the lever v46 upward.

The machine is supported upon two rear wheels 48, and these wheels areimounted upon crank axles 49,each. axle being'independent; and each crank axle' is journaled in the rear socket 26 of the rear boxing C. The beams, therefore, may be raised or lowered by the manipulation of these axles, and this is accomplished through' the medium of levers 49, which aresecured preferably to the inner ends of the axles, the said levers being provided with thumb latches 50, adapted to enter Vracks 5l, secured in any suitable or approved manner upon the rear boxings, as shown in both Figs. 1 and 4. The forward sockets 26a ofthe forward boxings C', are adapted for use when two or more of the cultivators are to be f coupled together to work in gangs, as it is rying them, and the angle or inclination may be readily changed by operating the worms 33. It -will be understood that the-worms maybe placed upon the inner side ofthe frame instead of the outer side, if'found more desirable.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent;- i
