CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 792,243, dated June 13, 1905. Application filed February 21, 1905. Serial No. 246,794.

To (LZZ whom it may concern:

Be it known that I, LEwIs E.VVATERMAN, a citizen of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Cultivators, of which the following is a specification.

The object of this invention is to control the action of the supporting-wheels by foot-levers supported by the beams by means of the tongue having a pivotal connection with the main frame and a bail connection between the tongue and beams.

The further object of this invention is to adjust the toothed quadrants when the beams are adjusted toward or from each other in order that the connection between the liftinglevers and beams may be directly over the connection between the beams and main frame, so that the beams will swing in substantially a horizontal plane.

In the accompanying drawings, Figure 1 is a plan view of my improved cultivator. Fig. 2 is a section on dotted line a a, Fig. 1. Fig.

3 is a side elevation in which portions are shown in section. Fig. A is a section on dotted line Z) Z), Fig. 1.

The main frame consists of the rear crossbar 1 and the forward portion 2, of U shape. Stub-axles 3 have a connection with the rear cross-bar of the main frame and each supports a carrying-wheel 4. A tongue 5 has a pivotal connection with the forward portion of the main frame at the point 6. To that portion of the tongue rearward of its pivotal connection with the main frame is secured a strap 7. having a depending rear end 8. A roller 9 is pivotally supported by the depending end 8 and bears against the under face of the rear bar of the main frame. Another strap 10 has a connection with the tongue, but located in connection with its under face.

A cross-shaft 11 is supported by the forward portion of the main frame by the brackets 12. Upon the shaft 11 are located two pendants, each having two branches 13 and 21 passes and connects it with the forward portion of the main frame. To the quadrant is pivoted a hand-lever 22, having the usual dog engagement with the quadrant. Upon the shaft 11 is mounted a hook 23, which is held by a set-screw 2 1. This hook engages the branch 14 of the pendant, which holds the pendant in connection with the shaft, and as the quadrant is connected to the pendant and also connected to the main frame the pendant is held in a vertical position. The pendant and quadrant are adjusted transversely of the main frame together, and it will be noticed that the hand-lever 22 is vertically over the lower end of the pendant. This relative position will always be maintained. To the lower end of the pendants are pivoted the beams 25 and 26 in a manner that they can be raised and lowered and moved transverse to the length of the cultivator, as in the act of cultivating. The rods 27 form a connection between the lifting-levers and the beams. Each of the arms 16 of the pendants supports an eyebolt 28.

To each of the beams is pivoted a foot-lever 29 and located diagonal to the length of the beam and each having a perforated projection 30. A rod 31 connects the perforated projection 30 with the eyebolt 28 and extends diagonally to the length of the beam.

From each of the beams extends a loop 32. From the forward portion of the main frame depend two horizontally-perforated brackets 33.

A bail is employed to connect the beams and comprises the horizontal section 34, guided by the brackets 33, and two vertical sections 35, guided by the loops 32. The vertical sections have an adjustable connection with the horizontal section by the set-screws 36. To the front face of the horizontal section 3 of the bail is connected an ear 37. A bolt 38 passes through the plates 7 and 10 and the ear 37, thereby forming a connection between the bail and tongue.

\Nhen the driver is located in the seat, his feet rest in engagement with the foot-levers 29, By a pressure of the feet against the footlevers in a forwardly direction the foot-levers, moving on their pivotal supports, will move the beams transverse to the length of the cultivator by reason of the foot-levers pulling on the rods 31, which are located diagonally across the beams. This movement of the beams will through the bail move the tongue on its pivotal connection with the forward portion of the main frame, and the roller 9 will move in contact with the rear cross-bar 1 of the main frame. By this movement of the foot-levers a natural position is given the feet of the driver and great power can be imparted to the foot-levers. As the pendants are adjusted transversely of the main frame, the beams will'be carried with them, also the quadrants, so that the same relation between the lifting-levers and beams always remain the same, which will allow the beams to swing in a horizontal plane.

I claim as my invention 1. In a cultivator, the combination of a main frame, beams having a swinging connection with the main frame, each beam pivotally supporting a foot-lever and located diagonally to the length of the beam, and a rod connecting the foot-lever with the main frame whereby a forward movement of the foot-lever will swing the beam transverse to the length of the cultivator.

2. In a cultivator, the combination of a main frame, beams having a swinging connection with the main frame, each beam pivotally supporting a foot-lever and located diagonally to the length of the beam, and a rod connecting the foot-lever with the main frame, and located beneath and diagonally to the length of the beam, whereby a forward movement of the foot-lever will swing the beam transverse to the length of the cultivator.

3. 1n acultivator, the combination of a main frame, beams connected to the main frame and adjustable bodily transversely thereof, and a quadrant and lever for each beam and adjustable bodily transversely of the main frame.

f. In a cultivatorthe combination of a main frame, pendants supported by the main frame, a quadrant connected to each pendant, a handlever for each quadrant, the pendants and quadrants adjustable bodily transversely of the main frame, and a beam connected to each pendant.
