DITCHING AND GRADING'PLOW.

SPECIFICATION forming part Of Letters Patent N0. 258,064, dated May 16, 1882.

' Application filed January 14, 1882. (No model.)

To all whom 'it may concern:

Be it known that we, FRANK A. HILL, of Benicia, in the county of Solano and State of California, and MosEsJ. CHURCH, of Fresno, in the county of Fresno and State of California, have invented a new and useful Improvement in Ditching and Grading Plows and we hereby declare that the following is a full, clear, and exact description of the same.

Our invention relates to plows; and it consists mainly in the improved and novel construction and adjustment of the extension of the mold-board, and in other details of construction hereinaftermore fully set forth.

Figure is a side elevation, and Fig. 2 a plarf view, of the improved apparatus.

In these drawings the plow is reprcsen ted as mounted upon an axle, the beam of the plow being connected thereto, as shown in Fig. 1. The axle is provided with cranks m w, and is unusually heavy. The wheels are provided with wide tires and with adjustable boxes H, which are bolted to the hub with three small bolts, and can readily be replaced when worn out or broken. The plow is of the slip-share class, and its depth is adjusted by means of the lever D, which is fixed, as shown more clearly in Fig. 1, to the rock-shaft V. This is mounted on suitable standards, and is provided at its ends with arms P P',Fig.2, which are connected to the crank-axles by means of links P P. The lever engages with a bent rack-bar, 1, by means of which it is held in any required position. To the beam, which is of the ordinary bent form, a permanent mold-board and landside are connected and securely braced. A movable or adjustable extension of the mold-board is shown at A. This is pivoted at the lower forward corner, as shown at R, and is held at the forward upper corner to the fixed mold-board by means of a bolt passing through a slot. This construction permits the movable mold-board to be raised to an angle of forty-five degrees, more or less, as may be required, to enable the operatorto adjust the machine to suit the soil in which he is working. The ditching mold-board is supported upon a lever, K, which is pivoted at 0?, Fig.2, and is capable of swinging laterally on this point. .It is supported on a bar, U, Fig.2, around which it moves toaccommodate itself to the different positions of the end of the movable mold-board A. The cross-bar is supported on suitable standards. The rear end of the lever K is provided with a lever, I, engaging with a rack-bar, J, on the lever Kand supporting by means of a chain the end of the detachable mold-board. This mold-board is also adjustable laterally, the angle which it makes with the landside being variable at will by means of the jointed bars 00, Fig. 2. These bars are connected to the mold-board and landside by means of suitable hooks and eyes or in any other convenient way, and may be increased or decreased in length, as required.

The landside is also composed of aiixed and removable part, L L, the latter being bolted to the former by means of bolts E E, and. when desired this part L may be removed with its appurtenances and with the ditching mold: board, and the plow used as a deep tiller.

In order to carry the landside when theplow is not working, we have provided a casterwheel, W, upon the end of a pivoted bent lever, S. The lever is pivoted at the end of the landside, and when the machine is not at work the lever is thrown forward into the position shown in Fig. 1, which brings the wheel under the end of the broadside, thereby slightly elevating it. When it is desirable to lower the landsidefor work the lever is thrown backward to trail upon the ground.

The pole T is fixed adjustably to the front cross-bar, t, of the frame and to the axle. Preferably it is clamped to the axle by a strap and bolted to the front bar by two or more bolts. This front bar is provided with a series of holes, so that the pole can be shifted laterally, and always be located in the centralline of draft in whatever position or manner the plow or mold-board is adjusted.

The plow-beam, frame-work, and all other appurtenances are preferably made of metal, except the pole and sustaining-lever K, which may be wood. The whole machine is constructed with a view to strength as well as for the special functions, and may be attached to a number of horses without danger of breakage in any of its parts.

Having thus described our invention, what we claim is- 1. In a ditching-plow, the combination of the carrying-wheels, the rook-shaft V, the plow names to this specification in the presence of having a permanent mold-board, the pivoted two subscribing witnesses.

extension A', having independent vertical and lateral adjustment, and the lever K, pivoted 5 to the rock-shaft and connected to the extension of the mold-board.

2. The combination, with the mold-board, of the extension A, pivoted at R, and having the pin and slot G, the support K, and the rack and 10 lever J I.

In testimony whereof we have signed our FRANK A. HILL. MOSES J. CHURCH.
