DITCH l NGF PLOW- SPECIFICATION formingpart of Letters Patent No. 470,491, dated March 8, 1892.

Application filed July 16,1891. Serial No. 399,742. (No model.)

To all whom it may concern:

Be it known that I, ISAAC JONES, a citizen of the United States, residing at Knoxville, in the county of Marion and State of Iowa, have invented certain new and useful Improvements in Ditching-Flows; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to an improvement in ditching-plows; and it consists in the certain peculiar features of construction and arrangement of parts more fullyhereinafter described, and definitely pointed out in the claim.

The object of -my invention is to form a plow for cutting ditches adapted especially for draining-tiles, which will be simple in its construction, embodying the fewest number of movable parts, and which can be readily transported to and from the place of operation. This object I accomplish by the construction illustrated in the accompanying drawings, wherein like letters of reference indicate like parts in the several views, and in which- Figure 1 is a perspective View. Fig. 2 is a top plan view, and Fig. 3 is a side elevation with the parts arranged for transportation.

In thedrawin gs, A represents the plow-beam supported on the front and rear axles B and B, upon which suitable wheels are placed, the axle B being pivoted to the beam on its upper side and the axle B rigidly secured on the upp r side of the front end of the beam. To retain the axle Bin a rigid position, I secure two straps O and O, pivoted on the axle on ends adjustably secured to the beam at the front of the axle, so that the axle willbe held in a rigid position at right angles to the beam when the plow is in operation.

When it is desired to transport the plow, the forward ends of the straps are loosened and removed from the beam and swung over a support for the same.

are attached to a suitable tongue D,'so that i the front axle may be moved to turn the machine.

In securing the axle B to the beam I in- I terpose a block E and insert a pivot-pin 6 directly through the axle and block. This block elevates the wheels so that the lower portions thereof are on the same plane as the lower parts of the frontwheels, thereby holding the plow in a perfectly horizontal position. F is a brace on the upper side of the axle B, extending forward and secured to the beam. On the rear end of the beam,to one side thereof, is rigidly secured an inclined mold-board G, having a flaring upper end inclining to one side and a tapering lower end terminating in a shoe G placed at anincline of less angle than the mold-board. This-moldboard has a backing of wood G which forms The side of the moldboard next to the standard is carried up vertically to form a plate H, which has its upper end rigidly secured to the beam. This plate is at right angles to the mold-board and acts as a retaining-wall for the earth that passes up over the mold-board, thereby conducting the same to one side of the ditch.

I isa parallel beam located on the side of the forward portion of-the beam proper, having interposed between a block I at its rear end and clevis-block I at its forward end, to which the power is attached. On the side of this supplemental beam I is a metallic bar J, extending back to point beyond the shoe. The rear end of this bar is provided with a vertical colter extending down to and attached to the lower end of the mold-board or point thereof, having a cutting front edge.

K is an inclined colter and brace secured to the rear end of the supplemental beam,

serve to sever the soil in advance of the plow or point, while the knives or colters serve to trim the walls of the ditch dug. The rear end of thebar J is bent outwardly, so that the upper end of the vertical colter attached thereto will engage the soil in the rear of the forward colter.

By the above-described construction it will be seen that as the power is applied to the forward end of the plow the same will be drawn into the ground, severing the earth and carrying it up themold-board off to one side of the ditch cut and in rear of the wheels. The power that I preferably use is a windlass or capstan; but any other desired means may be employed.

By placing the axles of the machine on the top of the beam and rigidly securing the other parts to the beam it is evident that all that is necessary is to turn the plow over, throwing the mold-board up. The braces are then detached and the tongue secured in place, when the device is ready for transportation.

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

In a ditching-plow, the combination, with the main beam having a mold-board secured to one side thereof and extending down at an angle, colters extending from the beam to mold-board, axles mounted on top of the beam, wheels on the axles, and adjustable braces on one axle for holding it in its adjusted position and to which a tongue is attached when the plow is reversed for transportation, substantially as described.

In testimony whereof I affix m y signaturcin presence of two witnesses.

ISAAC JONES.
