CULTIVATING-PLOW.

SPECIFICATION forming part of Letters Patent No. 662,613, dated November 27, 1900.

Application filed August 30, 1900. Serial No. 28,537. (No modelJ I T0 :LZ/Z whom it ntrty concern:

Be it known that I, CHARLES WELLS, a citizen of the United States, residing at Woodville, in the county of Tyler and State 0f Texas, have invented a new and useful (lultivating-Plow, of which the following is a specification.

My invention is an improved cultivating- .plow adapted for cultivating a numbervof rows of growing plants at a single operation, my improvements relating especially to the couplings for connecting the plow-beams to the axle and to the devices for raising the plows from the ground when turning at the ends of the rows and in driving the cultivator from one field to another.

My invention consists in the peculiar construction and combination of devices hereinafter fully set forth, and pointed out in the claims. p

In the accompanying drawings, Figure 1 is a side elevation of an improved cultivatingplow constructed in accordance with my invention, the near wheel being removed. Fig. 2 is a top plan view of the saine. Fig. 3 is a detail view.

The axle 1 is provided with the arch 2 and with the horizontally-disposed portions 3, near the ends of the axle at the inner ends of the spindles thereof, on which the supportingwheels 11 have their bearings. The tongue 5 is connected to the arch of the axle by bars 6 and clip-bolts 7. A cross-bar 8 is secured on the bars 6 either by means of clip-bolts or any other suitable devices. Yokes 9 are mounted on the cross-bar 8 and are normally retained in a vertical position by means of coiled springs 10, which are disposed on the lower pivotal sides of said yokes, are secured at one end to the bar 8, and have arms 11 at their free ends, which bear against the rear sides of the yokes.

On the portions 3 of the axle are secured couplings 12. Each coupling comprises an upper jaw 13 and a lower jaw 11i, which are provided in their opposing sides with an opening to receive the axle. Said jaws are provided at their front ends with ears or lugs 15 to receive the clamping-bolts 16, which serve to connect the front ends of said jaws together. Said jawsare provided, respectively, at their rear ends with rearwardly-extending arms 17 18, which are connected together by an adjusting coupling-bolt 19. The same is square in cross-section and is provided with a series of adjusting-openings 20, made transversely therethrough. It will be understood by reference to the drawings that the spindles 21 of the said coupling-bolt at the upper and lower ends thereof pass through and are adapted to turn in openings 22 in the arms 17 18 and that by means of the nuts or taps 23, screwed on the outer threaded extremities of the spindles of the bolt, the latter serves to clamp the rear ends of the jaws 13 1L]E together'. Each coupling 12 is secured on the axle and prevented from turning thereon by means of setscrews 21. The arm 17 of each coupling 12 is provided on its upper side at its rear end with a vertically-disposed bracket 25, in which is mounted a grooved roller 2G. Each bracket 25 is formed with a chain-guard 27, disposed below the roller 26. The bolts 16, which clamp the front ends of the jaws of the coupliugs 12 to the axle, also serve as means for the attachment of the rear ends of the draftbars 28 to the couplings.

The cultivators 29 each comprise a central beam 30, that carries a shovel 31, and a pair of side beams 32, bolted on opposite sides of said beam 30, said side beams carrying reversely-disposed cultivating-plows 32, which are abreast of each other and are adapted to throw the earth outward in opposite directions. To each of the cultivators is attached a single handle 33 when the machine is equipped as a walking-cultivator; but when the same is to be used as a riding-cultivator the handles 33 may be dispensed with. The front end of each beam 30 is provided with an angular fork 34, the forked sides of the front end of the beam bearing on opposite sides of the coupling-bolts 19 and being secured thereto by means of bolts 35, which are appropriately disposed in the adjusting-openings 20. Thereby the front ends of the plowbeams may be attached to the coupling-bolts at any desired vertical adjustment to dispose the cultivating-plows at any desired pitch or inclination when the same are in operation. It will be understood that as the couplingbolts 19 are adapted to turn in the couplings IOO 12 the said cultivators may be moved laterally when in operation as may be required, and it will be further understood that as the said cultivators are pivotally connected to the coupling-bolts by the bolts 35 the same may be swung in vertical planes, and hence the cultivators are adapted for universal movement, thereby enabling the plowman to manipulate the cultivators as may be re- On each beam 30 is secured an upwardlyextending hook 36. 'Supporting and elevating chains 37 are attached to' the upper sides of the yokes ll, as at 38. Said chains pass under and engage the lower sides of the rollers 26 and are attached to the hooks 36, which latter will engage any appropriate links ot the chains.

From the foregoing and by reference to the drawings it will be understood that the springpressed yokes ll and chains 37 support the weight of the cultivators and normally raise the saine from the ground.

In operation the plowman by depressing the handles 33 causes the cultivating shovels and plows to operate as may be required between the rows of plants, and when the end of a row is reached and it is necessary to turn the plowman releases the handles 33, whereupon the spring-pressed yokes and chains elevate the cultivators from the ground and permit the machine to be turned. Said springpressed yokes and elevating-chains also keep the cultivators in elevated position out of contact with the ground when the machine is being driven from one field to another.

It will be understood that the couplings l2 are rigidly attached to the axle and do not `turn thereon, and when the cultivators are raised and lowered there is no wear on the axle, the bolts 35 forming the pivots for vertically moving the cultivators.

The cultivator-shovels may be adjustable on their standards and adapted to be turned to any necessary angle and to be sharpened without the necessity of removing them from their standards. Fenders may also be employed in connection with the cultivators to shield the plants and prevent them from being broken or covered by clods or stones.

Harrows of suitable form for cultivating between the rows may be substituted for the cultivators when desired for cultivating Vyoung and small corn.

Having thus described my invention, I 55 claiml. In a cultivating-plow, the combination of the axle, the coupling comprising the two sections bolted together andy secured one above the other on the axle, the vertical adjusting-bolt connecting said sections of the coupling and adapted to turn and the cultivator having the beam pivotally connected to said adj Listing-bolt, the axis of said pivot being at right angles to that of said adjusting-bolt, substantially as described.

2. In a cultivating-plow, the combination of the axle, the coupling comprising the separable sections having the forwardly-extending lugs 15 and the rearwardly extending arms, the bolt 16 in said lugs and connecting the front ends of said sections together, the adjusting-bolt connecting the rearwardly-extending arms of said sections together and adapted to turn therein, and the plow-beam pivotally att-ached to said adjusting-bolt, substantially as described.

3. In a cultivating-plow, the combination of the axle, the coupling comprising the sections bolted together and secured on the axle, said sections having the rearwardly-extending arms, the adjusting-bolt having the spindles at its upper and lower ends in openings in said rearwardly-extending arm, adapted to turn therein, said adjusting-bolt having the series of adj listing-openings, and the cultivator having its beam connected to said adjusting-bolt by a bolt disposed in one of said adjusting-openings, substantially as described.

4. In av cultivating-plow, the combination ofthe axle, the coupling rigidly secured thereon, the coupling-bolt adapted to turn in said coupling, the cultivator having the beam pivotally connected to said coupling-bolt, the spring-pressed yoke mounted on the frame of the cultivating-plow,the chain attached thereto and engaging a hook on said beam, and the roller carried by the coupling and engaged by said chain, substantially as described.

In testimony that I claim the foregoing as IOO my own I have hereto affixed my signature in Witnesses:

STEPHEN P. WEST, GORDON BULLITT.
