SPECIFICATION forming part of Letters Patent No. 356,094, dated January 18, 1887.

Application filed November 9,'1886. Serial No. 218,390. (No model.)

To all whom, it may concern:

Be it known that we, DENNIS S. BLUE and LEANDER HALTER, citizens of the United States, residing at Fremont, in the county of Sandusky and State of Ohio, have invented certain new and useful Improvements in Oultivators; and we do hereby that the following is a full, clear, and exact description of the same, reference being had to the annexeddrawings, making a part of this specification, and to the letters and figures of reference marked thereon;

Figure 1 of the drawings is a perspective view of our improved cultivator; Fig. 2, a top plan View partly in section; Fig. 3, a detail sectional view taken on line as x of Fig. 2; Fig. 4, a similar view taken on line y y, and Fig. 5 a detail sectional view through the seat and seat-support.

The present invention has for its object t0 provide a practically-constructed and easilyoperating cultivator; and it consists in the details of construction substantially as shown on lthe drawings and hereinafter described and claimed.

In the accompanying drawings, the frame Aris composed of tubing a, coupled together at their forward ends by elbows I), the sides of the lrame having connected thereto, by coupling-sections c, a transverse brace-rod, (Lto which is connected the tongue of the cultivator, as shown at B. This tongue in the present instance is formed of the two sections ef,- but, if preferred, a single section may be used.

The crank-axles C at their upper ends are connected to the coupling-sections c and eX- tend down and outwardly, and upon their eX- tremities are mounted the wheels D. rIhe upper ends of the axles Care screw-threaded, by means of which they. are securely connected to the coupling-sections c, as shown in Fig. 3, as are also the ends of the transverse brace d. The ends of the tubes @,which form the frame of the cultivator, are also screw-threaded to couple with the elbows b. The lower. end of the crank-axles C have connected to them braces E, the ends of which are widened, as shown at g, to form ashoulder or collar for the hub of the wheel, the upper ends of said braces being connected in any suitable manner to the forward end of the frame of the machine.

The cultivator-beams are of the ordinary shape, and at their front ends are connected together to form a slot, h, to receive the drawbar F. There are shown three beams, G, to each cultivator, their rear ends being curved in the usualmanner for attaching thereto the shovels H. In forming the slots h the outer ones of the beams G are-formed of one piece of metal, and the middle beam disposed between them and fastened in position so that a slot will be left, as above described.

The draw-bars F are curved at their upper ends and bifurcated, as shown at z', to receive grooved rollers k, which work on guides I, suitably attached to transverse rods Z, connected to suitable 'clips projecting from the under side ofthe frame of the machine, or in any other suitable manner attached thereto, as found preferable. The rods Z form the inner guide for the rollers k, thereby retaining the pulley in position while working laterally on the guides, when the cultivators move laterally in either direction. The draw-bars F have perforaiions m at their lower ends to receive bolts n, whereby the cultivator-beams may be raised or lowered to regulate the depth of cultivator, as shown more clearly in Fig. 4, a suitable nut, o, engaging with the screwthreaded end of the bolts. The cultivators may also be raised or lowered by means of the double-crank arm K, suitablyjournaled to the sides of the cultivator-frame, as shown at p, and to clips q on thev rear extremities of the tongue-sections ef.'

The double crank arms or levers K are connected to the cultivator by means of standards or links L, said levers being pivoted or loosely connected to the upper ends thereof,

the standards being bifurcated to embrace the sides of two of the cultivator-beams. The

double-crank levers are bent to form handles,

ner ends of each section, a suitable distance ICO throughout its length, have perforationse, through which passes a suitable screw-bolt, w, upon the end of which engages a tightening-nut, w', to secure the spring-sections together and also secure the seat thereto. By the above means provision is'made for lengthening or shorteningI the springto increase or diminish its iexibility. The rods O, to which the spring is connected, extend through the tubesa of the frame, and are held therein by setscrews a', and areconsequent-l y adjustable, to change the position ot' the seat as circumstances require. By lifting the curved handles r of the double-crank levers K the crank portion thereof, tonwhich the bifurcated standards L are connected, when brought forward beyond a vertical line will fall of its own weight until the standards rest against the transverse brace d, which will securely hold the cultivators from ot'f the ground.

One or both of the cultivators may be provided with the usual handle, P, and the tubes 'and couplings forming the frame of the ma` chine render the frame not only strong and durable, but comparatively light.

As will be noticed, the coupling-elbows b of the frame A are provided with depending lugs bf as a means for attaching thereto the extremities of the transverse rod Z, held thereto by means of nuts c', engaging the screw-threaded ends of the rod. The coupling-sections c are also provided with like lugs, for connecting thereto the rear one of the rods Z. The eyes or clip p, which form the bearings for the double-crank levers K, project from the rear end of the coupling-sections c, thereby forming a strong and permanent fixture for the levers.

When the cultivators are moved from right to suit different persons.

As previously described, two different means are employed for connecting the sleeves s of the spring to the extremities of the rods O, viz: a key, t, and a latch, u, said latch acting as a hinge, so that when the key is removed one end of the spring may be detached, or by disengaging the latch with the rod 0 this end maybe removed, while the opposite end is held bymeans of the key, thereby enabling the driver to get in and out of his seat. The rods O are drawn out of the tubes a sufficiently so that the driver can balance the tongue, this being an important feature of our invention, as well as other details of construction, hereinbefore described. The bifurcated standards L are-.connected to the beams of the cultivator by means of a strong and substantial the beams, and also forming a brace therefor,

the two serving to steady the cultivator when in operation.

As will be noticed, two rods Z are shown, for convenience of using a riding Lor walking Cultivator, the forward one of said rods being used for attachment thereto of a ridingcultivator. One or both of said cultivators ymay be provided with a stirrup, It, to receive the foot of the driver, to move the cultivator to either the right or the left. The walking-cultivator is made by asimple change,

the rod Z being placed in the rear of the riding-cultivator at the proper distance, so as to. take the draft andY weight of the tongue,

in order to balance without the weight of driver, as is more clearly shown in Fig. 2, the same connections being made between the cultivator beam and rod; but the `draw-bar F is reversed, as shown in dotted lines, Fig. 4.

By this change the cultivator is kept in the same line with the riding-cultivator, and the manner of attaching the cultivators prevents their hanging back of the wheels when turning. f

One draw-rod Z will answer for both riding and walking cultivator when either is used separately. The stirru p R is detachable, so that it may be removed when the device is used as a walking-cultivator.

Having nowv fully described our invention, what we claim as new, and desire to'secure by Letters Patent, is-

1 In a frame i'orcultivators, the metal tubes @coupling-elbows b, and couplingsections c, roo having depending lugs, as shown, and the former having eye-clips p, iu combination with the transverse brace (Z, rods Z,.and the doublecrank levers la, links L, and beams G, substantially as and for the purpose specified.

2. The combination, with the extensible rods O, of the extensible or adjustable spring seatsupport N, provided at its extremities' with sleeves s, and detachably connected to the ends of the rods,substantially as and for the purpose 1ro set forth.

3. ln a cultivator, the frame A, constructed as described, the transverse guides l, and rods Z, in combination with the plow-beams, the crank-levers K, for raising and lowering them, i 15 andthe curved and bifurcated draw-bars F, provided with grooved rollers k, substantially as and for the purpose set forth.

In testimony that we claim the above we have hereunto subscribed our names in the .12o presence of two witnesses.
