SPECIFICATION forming part of Letters Patent No. 575,872, dated January 26, 1897.

Application filed July 21,1894. Serial No. 518,237. (No model.)

T0 LZZ whom, t IIL/Ly concor/L:

B e it known that I, JAMES FRANK BoLLIN- GER, a citizen of the United States, residing at Hickor in the county of Catawba and State of North Carolina, have invented a new and useful Cultivator, of which the following is a specification.

My invention relates to cultivators, and has for its object to provide a simple, inexpensive, and eiiicient device of the class named with which any desired number of shovels may be employed irrespective of the handles and braces, each cultivator-beam being braced at the point of greatest strain in order to form a compact structure.

Further objects and advantages of this invention will appear in the following description, and the novel features thereof will be particularly pointed out in the appended claim.

In the drawings, Figure 1 is a perspective view of a cultivator constructed in accordance with my invention. Figs. 2 and 3 are transverse sectional views taken, respectively, in the planes of the front and rear transverse braces. Fig. llisa detail sectional view of the rear end'of the draft-beam to show the attachment of the central standard thereto. Fig. 5 is a detail perspective view of the wedge-shaped spacing-plate.

Similar numerals of reference indicate corresponding parts in all the figures of the drawings.

l designates a draft -beam to which, by means of a transverse bolt 2, are secured the front ends of the rearwardly-inclined handles 3,downwardly-convergent braces 4 extending from said handles near their rear or grip ends to the contiguous or rear end of the draftbeam.

Any desired number of plow-beams may be secured to the draft-beam upon opposite sides thereof; but in the drawings I have shown two opposite front beams and a corresponding number of rear beams, the front beams being indicated at 10 and the rear beams at 1l. Each plow-beam is provided at its front end with an ear arranged to bear against the side of the draft-beam, the ears of the front plowbeams being secured to the draft-beam by means of bolts 17 and the ears of the rear plow-beams being secured to the draft-'beam by means of the bolts 18.

The body portions of the front and rear plow-beams are arranged at inclinations to the draft-beam, diverging rearwardly therefrom, and the rear portion of each plow-beam is arranged approximately parallel with the draft-beam,whereby the draft upon the standards 12 and 13, which are integral, respectively, with the front and rear plow-beams, is in a direction parallel with the draft-beam.

In order to hold the rear ends-of the body portions of the plow-beams at the desired deiection from the line of the draft-beam, I employ front and rear transverse braces 22 and 23, each comprising relatively adj ustable sections or members overlapping at their inner or contiguous ends above the plane of the draft-beam and resting upon the upper edge thereof. The overlapping extremities of the sections or membersof the transverse braces are provided with series of perforations for .the draft-beam by the rearward pressure upon the front and rear shovels 8 and 9, and the point of engagement of said braces with the plow-beams insures the efficient coperation of the braces and beams.

It will be seen that any desired number of plow-beams may be employed to carry the desired number of shovels, and in addition to those above described I preferably apply a standard b to the draft-beam near its rear end to carry a shovel 7. Said standard G is provided with a brace l5, secured in place at its rear end by means of a bolt 16, as clearly shown in Fig. 4. The upper end of the standard 6 is bifurcated, and the extremities thereof are connected above the plane of the upper edge of the draft-beam by means of a transverse bolt 14.

When it is desired to change the interval between the rear ends of the plow-beams and the draft-beam to suit the intervals between ICO rows to be cultivated, it may be accomplished by the adjustment of the sections or members of the transverse braces 22 and 23, and in order to insure the tightening of the bolts 17 and 18 and the pressure of the heads and nuts thereof against the surfaces engaged thereby I employ the wedge-shaped spacingplates 20, one of which is shown between the ear at the front end of one of the front plowbeams and the contiguous surface of the draftbeam, and another of which is shown between the ear at the front end of one of the rear plow-beams and the contiguous heads of the bolts, said plates being perforated to receive the bolts.

From the above description it will lbe seen that the handles and the braces thereof are secured to the draft-beam independently of the plow-beams, and that the plowbeams may be adjusted as desired or may be removed to provide the necessary number of shovels without ailectingthe handles. Either of the transversely opposite plow-beams is detachable independently of the other to provide for using the desired number of plow-standards, and it is equally obvious that when a plowbeam is removed the corresponding section of the transverse brace which is employed for holding said plow-beam in position may also be detached, the other section of the same brace being efficient for the designed purpose independently of the removed section. Thus any desired number of plow-beams maybe employed, and only those brace-sections which are attached terminally to the plow-beams in use are allowed to remain in position upon the cultivator. The remaining brace-sections are removed with the detachable plow-beams. Hence it will be seen that the arrangement of the brace-sections with overlapping inner eX- tremities secured by common bolts accomplishes the object desired with a simple construction, the one bolt employed being adequate for securing either or both brace-sections, according to the number which may be required to suit the number of plow-beams in use.

The clips 24, by which the rear portions of the plow-beams are secured to the outer eX- tremities of the braces, consist of single stems engaged at their upper extremities above the planes of the braces by nuts and provided at their lower extremities with hooks engaging the lower edges of the beams, whereby said clips are adapted to turn to suit the adjustment of the plow-beams or their deection from their normal positions. The sin gle stems by which the clips are attached to the braces have the effect of swiveling the clips thereon.

Having described my invention, what I claim is- A cultivator comprising a sectional draftbeam having attached handles and carrying a plow-standard adjustable longitudinally of the draft-beam and provided with means for clamping it at the desired adjustment, pairs of transversely opposite plow-beams detachably secured by common bolts to opposite sides of the draft-beam, each plow-beam being provided at its front end with an ear appl-ont mately parallel with the draft-beam, engaged by said bolts, and adapted to be deflected from the plane of the plow-beam by the insertion of a wedge-block, a rearwardly and outwardly deflected body portion, and a rear port-ion parallel with the draft-beam and terminatingin a plow-standard, either of thc opposite plow-beams being detachable independently of the other to provide the desired number of plow-standards, and transverse braces comprising relatively-adjustable sections terminally attached to the plow-beams contiguous to said rear portions and secured at their overlapping inner extremities by engaging bolts which are also engaged with the draft-beam, either section of said transverse braces being adjustable independently ofthe other, and also being removable independently of the other to suit the number and locations of the plow-beams, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two Witnesses.
