DISK CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 603,167, dated Apr126, 1898.

Application led November 28,1896. Serial No. 613,758. (No model.)

class described which will be composed of but few parts and be light and strong and one of such peculiar construction that the disks can' be easily adjusted bythe driver to' suit the requirements of the occasion.

Having this object in view, the invention consists of a disk cultivator comprising those novel features and combinations of pearing more in detail hereinafter;

In the accompanying drawings, Figure 1 is a side elevatiomFig. 2a reary View, Fig. 3 a plan view, and Fig. 4 a perspective view, of the complete machine,

The draft-tongue. is designated by the numeral 1, and atthe'rea'rof -this draft-tongue there is a drivers seat 2, whilethe machine is mounted on suitable traction-wheels 3.

The numeral 4 designates an adjustmentbox which is in the shape of a casting, connected to the rear portion of the draft-beam underneath thelatter.

5 and 6 indicate two L-shaped frame-pieces or horizontal bars,which have their adjacent ends secured in openings or sockets in the opposite ends of the adjustment block or box 4, the arrangement being such as to allow said frame-bars to rock in said sockets or openings. When it is desired to hold the bars at any [ixed adjustment, it is done by means of setscreWs 7 and'8,vwhich serve to prevent endwise movement of the `frame-bars, but which when loosened permit the frame-bars to be rocked in rtheir bearing in the adjustmentbox. The pendent rigid arms at the outer ends of these frame-bars extend down through perforations in the boxes 17 and 18, in which the disk-shafts 13 and 14 are journaled, the arrangement being such as to give the shafts a swiveling connection with said pendent arms.

parts ap- 9 and l10 indicate pendentl arms intermediate the adjustment-box 4 and the outer rigid arms of the frame-bar and sleeved upon the horizontal portions of said arms or otherwise pivotally connected therewith to allow them to swing independently of the rigid pendent arms of said frame-bars. These pendent arms 9 and l10 extend through the boxes in which the disk-shafts 13 and-14 are journaled, the

said boxes havinga swiveling connection with 19- and 2O indicate scraper-bars carried by the respective sets of boxes in which the shafts 13 and 14 are journaled.

2121 indicate converging rods connected attheir rear ends with the lower ends of the rigid pendent arms of the frame-bars and converging thence forward, where they pass through a horizontal slot in the tongue indicated at 22. The tongue is also provided with a guide-slot 23.

The numeral 24 designates a cross-beam which has a pivot-bolt 25, that passes through the slot in the tongue and is adapted to move therein. It is not clamped at any point, so it will be seen that this beam has an adjustable pivot-that is to say, the beam can be moved longitudinally in relation to the tongue and yet at all times be pivoted so that it may swing horizontally.

The lnumeral 26 designates a rearwardlyextending shifting lever which has its forward end rigidly connected to the crossbeam, and this lever has a dog adapted to ride on and engage with a transverse rack 27, whereby the lever may be locked.

The numeral 28 designates a controllinglever of ordinary construction, which is pivoted to that portion of the rod 21 that is journaled in the frame'and has its lower extremity pivoted to the tongue. This controllinglever is connected to the cross-beam.

The numerals 29 and 30 designate rods which connect the ends of the cross-beam with the lower portion of the supplemental frame-pieces.

At 3l there is shown a foot-rest for the driver, which can be raised or lowered, as desirable.

The operation is extremely simple and as follows: When it is desired to give inclination to the cult-ivator-disks, the shifting lever can be moved and said disks and their shafts will be inclined to any desired degree, as the lever can be locked at any point. If it is desired to raise and lower the disk-shaft and disks, the controlling-lever can be moved either forwardly or baekwardly, as the case may be, thereby rocking the horizontal arms of the L-shaped frame-pieces in their sockets in the block or ad justment-box by the simultaneous forward or backward movement of both the rigid and the swinging pendent arms of the disk-supporting frame.

Having thus described the invention, what is claimed as new isl. In a wheeled disk cultivator, the combination with the draft-beam, of the disk-supporting frames pivotally connected therewith and having each a pendent rigid arm and a pendent arm, adapted to swing on the horizontal frame-arm the disk-shafts having a swiveling connection with said arms, an adjustable cross-bar connected with the pendent swinging arms for simultaneously swinging the disk-shafts on the rigid arms for adjusting the angle of presentation of the disks, and means for adjusting said cross-bar longitudinally upon the machine.

2. In a wheeled disk eultivator, the combination with the disk-shafts and disks carried thereby, of overhanging frames pivoted to swing in a vertical plane and having pendent rigid arms pivoted to the disk-shafts, supplemental suspending arms pivotally connected to the disk-shafts and also pivoted at points in alinement with the pivotal points of the suspending frames, means for swinging the suspending frames forwardly and upwardly, and independent means for swinging the supplemental arms independently of the suspending frames, whereby the disk-shafts can be simultaneously set at any desired inclination to a transverse line.

3. In a disk cultivator, the combination with depending frame-pieces adapted to swing upwardly, of supplemental pivoted members, sets of cultivator-disks carried by the main frame-pieces and the supplemental members, rods connected to the frame-pieces and movable longitudinally of the machine, a controlling-lever connected to said rods for operating said frame, a pivoted cross-bar, rods connecting the same to the supplemental members,a shifting lever adapted for lateral movement and to which the controlling-lever is pivoted, and means for locking the said shifting lever.

4. In a wheel disk cultivator, the combination with the pendent rigid arm of the supporting-frame pivoted to swing forwardly and upwardly, of supplemental members pivoted to the frame-piece and also adapted to swing forwardly and upwardly, disk-shafts pivoted to the frame-piece and to the supplemental members, disks carried by said shafts, a crossbar pivotally connected with and movable longitudinally of the machine, a controllinglever having its extremity pivoted to the main frame and which is also pivoted to the cross-bar, rods connecting the ends of said cross-bar and the supplemental members, a shifting lever secured to the cross-bar for adjusting the angle thereof, and means for locking said lever at any desired adjustment.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
