CULTIVATO R.

SPECIPICATIOlHorming part of Letters Patent No. 324,720, dated August 18, 1885.

(No model.)

To ctZZ whom it may concern Be it known that I, Osciin L. NEISLER, of the city of Indianapolis, county of Marion, and State of Indiana, have invented certain new and useful Improvements in Cultivators, of which the following is a specification.

My said invention consists in certain im provements in the construction and arrangement of the plow-bean1 attachments, and of spring-supports for carrying the same, as will be hereinafter more particularly described and claimed.

Referring to the accompanying drawings, which are made a part hereof, and on which similar letters of reference indicate similar parts, Figure l is a top or plan view of a cultivator embodying my said invention; Fig. 2, a side elevation of the same, one of the wheels being removed to show the construction more clearly; Fig. 3, a longitudinal sectional view, looking upwardly from the dotted line 3 3 in Fig. 1; Fig. 4, a rear elevation of one-half of the cultivator; Fig. 5, a detail horizontal section on the dotted line 5 5 in Fig. 4 on an enlarged scale; Fig. 6, a detail rear elevation of one of the bearings for the plow-standard; Fig. 7, a detail sectional view of the upper end of the supporting-spring and adjacent parts on the dotted line 7 7 in Figs. 1 and at; Fig. 8, a detail sectional view of the lower endof the supporting-spring and adjacent parts, and Fig. 9 a detail sectional View of the connection between the stud axles for the wheels and the vertical part of the arched axle on the dottedline 9 9 in Fig. 2.

111 said drawings, the portions marked A represent the arched axle of the cultivator; B, swinging supports attached to the front cross-beam ofsaid axle; O, plow-beams pivoted to the lower end of said swinging supports; 1), the plows, and E springsupports for the plows and plowbeams.

The vertical portions of the axle A are formed in two branches, as shown most plainly in Fig. 2, and the upper horizontal portions thereof are thus made double, thus giving the tongue A two bearing-points thereon, where it is secured by bolts a, as shown, and also permits the swinging supports to be attached considerably in advance of the spring- The cross-beams or upper portions may be slotted at the ends where they are attached to the upright portions, and the width of the cultivator thus varied, if desired. The lower ends may also be provided with a sliding connection, and be thus adapted to be varied in height by. the proper arrangement of the bolts a", which connect them to the stud axles a, on which the wheels A are mounted. I have shown (as seen most plainly in Figs. 4 and 9) slots in the vertical portions, with bolts a passing through them and flanges on the studaXles. The opposite sides are serrated, and correspondinglyserrated washers (formed in this case as a part of the hooks to which the stay-chains are connected) are provided, and by the proper manipulation of these bolts and washers the desired adjustment can be easily made, as will be readily understood.

The swinging supports B are secured to the under side of the forward cross-beam of the axle A in such a manner as to freely swing back and forth in the line of draft, but are not permitted to swing sidewise. The means shown consists of a bar, A, bolted to said cross beam, and pivots to, entering its ends. The lower ends of said swinging supports are prevented from swinging too far forward while the cultivator is being used by stay chains b, which connect their lower ends to a point on the axles behind them, preferably by hooks If, which also form washers, as above specified. Draft-rods b are also connected to these swinging supports near their lower ends, and at still another point, preferably between the staychains and the draft-rods, are hearings in which the rock-shafts C, forming in effect part of the plow-beams, are located.

The plow-beams O are mainly composed of two straight bars, pivoted at their forward ends to the rock-shafts G, and at their rear ends are provided with semicircular bearingplates 0", in which are bearings for the stand ards of the plows.

The standards of the plows D are mounted in the bearings provided therefor in the semicircular bearingplates G attached to the plowbeams. Extending inwardly from each of these standards is a projecting arm or bar, d or d, which are rendered adjustable on each other by a series of boltholes and a bolt, (1, provided therefor, and the plowsniay thus be I bar by bolts 6.

adjusted to a greater or less distance apart. Upon these arms or bars may be mounted, if desired, a clip, d*, to which the handle D may be secured, and the same bolt. 61 may pass through the handles, these clips, and said arms, and thus secure the whole together, as shown, although any other arrangement for attaching the handles may be provided, if desired. The bearings in the semicircular bearing-plates C are rendered adjustable by being divided and having interlocking notches and projections c, as shown, and a bolt, 0 by which they may be drawn together, as shown most plainly in Figs. 1, 4, and 6, and thus as the bearings become loose by wear they may be tightened up and restored to. their normal condition.

By the arrangement of these plows and plow-beams, the latter being attached by pivots to a rock-shaft and the former being attached to said plow-beams by pivot-bearings, it will be readily seen that the plows may be either moved up or down or swung from'side to side without varying their relation to the line of draft.

The springs E are secured to the hangers E upon the rear cross-bar of the axle A by pivots c, said hangers being secured to said cross- Said springs extend down and forward to near the lower end of the swinging supports B, and are provided upon their lower ends with clips 6'. At the upper end is a tension-regulating device, E the upper portion of which is slotted, as shown most plainly in Fig. 7, and is secured inside the hanger E by the same bolt, 6, which secures said hanger in position. Rigidly secured to the rock-shafts O are arms E, which extend rearwardly and pass through the clips 6 on the lower ends of the springs E. The operation of these devices is, when the plows are raised up, that the clips'e slide back along the arms E", and when the plows are released the clips 0 grip the said arms, and thus secure the plows in raised position. When the plows are down, as when in work, the relative position of the clips and arms is such that said arms slide freely back and forth through said clips the slight distance rendered necessary by the movement of the plows. These springs press down somewhat upon said arms, and thus aid in forcing the plows into the ground, as will be readily understood, and they thus serve two distinct purposes-that of helping to keep the plows into effective work and of supporting said plows when out of work. The latter purpose, however, may be served by hooked rods a secured to the cross-beams of the axle A in a common manner; but the spring-supports are regarded as possessing some advantages. WVhen it is desired to vary the tension of these springs IE, it may be done by loosening the bolts 6, slipping the devices E" so as to operate with more or less force upon said springs, as desired, and again tightening said bolts. These springs .E are so arranged lateral movement thereof to a short distance,

which is desirable.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, in a cultivator, of the arched axle, the vertical parts of which are composed of two branches, and having two upper portions, swinging supports pivoted to the ends of the bar A, secured to the under side of the front top part of the axle, plowbeams and draft-rods pivoted to the lower end of said swinging supports, and stay-chains connecting the lower ends of said swinging supports to the lower part of the axle, substantially as set forth.

2. The combination of the double-arched axle A,having swinging supports B secured to its forward portion, plow-beams secured to the lower ends of said swinging supports, the plows thereon, arms secured to the rock-shafts of said plow-beams, and springs secured to the rear portion of said double-arched axle and engaging with said arms, substantially as set'forth.

3. The combination of plow-beams'pivoted at their forward ends to swing in both directions, semicircular bearing-plates secured to the rear ends thereof, and plows mounted in said bearing-plates and provided with connectingarms which extend from one to the other, substantially as described, and for the purposes specified.

4. The combination, with the plows and plow-beams, of bearings connected to said beams for said plows, the two halves of which are provided with notches and projections which interlock, and bolts by which the fit of said bearings on the shanks of the plows may be adjusted, substantially as shown and specified.

5. The combination of the double plowbeams G, semicircular bearing-plates G pivoted to the rear ends thereof, plows D, the

standards of which are pivotally mounted in bearings in said plates, and are provided with inwardly-projecting arms d and d, which lap by each other, and a bolt, (1", which passes through said arms and secures them together, said projecting arms being provided with a series of holes, whereby the distance between the plows may be adjusted, substantially as set forth.
