TILE-DITCHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 755,012, dated March 22, 1904. Application filed December 15, 1902. Serial No. 135,354. (No model.)

To all whom it may concern:

Be it known that we, EDWARD J nsonxn, residing at Bellevue, in the county of Huron, and CHARLES WV. J ESOHKE, residing at Lorain, in the county of Lorain, State of Ohio, citizens of the United States, have invented certain new and useful Improvements in Tile- Ditching Machines; and we do declare the following to be afull, 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 the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in excavators, and has particular reference to that class known as tile-ditching machines.

The object of the invention is to provide a machine that will cut a ditch or trench of the desired width and depth, raise the dirt therefrom to the surface of the ground, and force the same a sufficient distance from said ditch or trench to prevent it falling back thereinto.

Further objects and advantages of the invention will be obvious from the detail description when taken in connection with the drawings.

The invention consists of a ditching-machine provided with an excavator in combination with vertically and horizontally adjustable wings or spreaders. i

The invention further consists in the construotion and novel arrangement of the several parts of the device hereinafter described, illustrated in the drawings, and more particularly pointed out in the claims hereunto appended.

In the drawings, Figure 1 is a side elevation of the machine embodying our invention. Fig. 2 is a top plan view thereof. Fig. 3 is a detached view of the excavator and showing suitable guides secured on the under side thereof. Fig. i is a perspective view of one of the adjustable wings or spreaders. Fig. 5 is another form thereof. Fig. 6 is a view of the extensible axle, showing the manner of lncreasing or dnnmishing the length thereof;

- and Fig. 7 is a detail of themeans for holding the wings or spreaders in normal position.

Like letters indicate corresponding parts in all the figures.

Referring to thedrawings by letters, A indicates the axle of the device and consists of the parts A A and the spindle-bars A A the said axle being so constructed that its length may be readily increased or diminished, as desired, and a a are the wheels.

B indicates a central beam or support secured in and set at right angles to said axle and is held rigidly in that position by stays or braces Z2 6. The forward end of this beam B is bifurcated, being provided with the arms B B. Into the bifurcated portion is set and suitably pivoted, between the arms B B, a rack-beam or support O, as shown, the forward end of which extends beyond the cuttingpoint of an excavator H and is provided with a pivoted bifurcated post D, into which is journaled a colter-wheel E, as shown. To each of the arms (Z (Z of the bifurcated post D is secured an angular cutter-blade d, which extend back toward the point of the excavator H and having their lower cutting edges projecting below the tread of the colter-wheel E, as shown. On the lower forward end of this rack-beam C, above and below its pivotal point, is secured an excavator H, which has its lower end or point slightly bent, as shown at h, and the upper end of which is split and curved upward and outward, so as to set on each side of said beam, as shown at [Ll h. At the lower end of this excavator H, set into a suitable opening ]L2 or secured thereto in any suitable manner, is the lower end of a cuttingblade f, the upper end of whichcuttingblade is firmly secured in any convenient manner to the beam O on a line at an angle to the plane of the direction of the machine.

Upon the beam or support B, to the'rear of the rack portion 0 of the beam O, we mount a suitable bracket G, into which is journaled a cog-wheel Gr, adapted to mesh with the rack c on the beam O and be operated by a worm G set in the upper portion of said bracket, which worm is in turn operated by a hand-wheel G To each side of said beam O and beneath the excavator H we mount suitable guides K K, and on the rear part of the beam B, forward of the axle, we mount two sets of guides L L, a set being mounted on each side of said beam. The guides L L are in line with or project above said beam, while the guides L L project below the level of said beam.

M M are horizontally and vertically adjustable Wings or spreaders connected to and slidably mounted on said guides K K L L L L, as shown. On the inner rear portions of said wings or spreaders are rigidly secured suitable arms N N N N, provided with openings or guides n a n a in the free ends thereof, which said openings are adapted to fit over and slide upon said guides L L L L on each side of said beam B, and to the inner front end of each of said wings or spreaders is at tached an arm m, adapted to fit over and slide upon the guides K K. On the front ends of said wings or spreaders M M, to the outside thereof, may be loosely pivoted sections or points M M, having their rear ends pivoted to the outside of said wings or spreaders, and on the front inner end of each section is provided an arm m, having an opening therein also adapted to fit over and slide upon the guides K K. Instead of these points or sections M M being pivoted they may be rigid with said wings or spreaders without affecting the operation of the device.

O O are suitable shoes secured to the lower inner sides of the wings or spreaders for the purpose of preventing said wings or spreaders cutting into the ground as they pass over the surface thereof. The arms N N of the wings or spreadersare provided with suitable cam-levers N or other means for the purpose of holding said wings or spreaders in any de sired position on said guides. On the rear end of each wing or spreader is preferably secured a lump-catcher P and is designed to prevent loose lumps rolling back into the ditch. p is a spring secured to the beam B and the rear end of the spreader to hold the same in normal position.

The operation of the device is as follows: When it is desired to cut a ditch orv trench, the excavator is set to cut to the desired depth by means of a hand-wheel G and the wings or spreaders are raised both vertically and horizontally until the lower edge thereof will rest upon and run along the top of the ground.

The machine is then started, the cutter-blades secured at each side of the colter-wheel will cut the ground the width of the proposed ditch, and the excavator will enter the ground and cut and force the dirt up and out of the ditch upon the wings or spreaders, which in turn will throw the dirt to either side of the ditch and clear thereof. The operation of setting and resetting the excavator and wings is continued from time to time until the ditch has been .cut to the proper or desired depth. As the ditch is cut deeper and deeper the wings or spreaders are raised higher and higher, so that they will remain on the surface of the ground, as is evident. It is also to be noted in this connection that the wings or spreaders may be adjusted independently of each other. This independent adjustment is frequently found desirable and sometimes necessary when cutting ditches on hillsides, &c. It will be further noticed that the wings or spreaders commencing at the excavator diverge toward the rear, whereby the dirt is pushed sufiiciently far from the edge of the ditch to prevent it rolling back when the machine has passed.

Having thus described our invention, what we claim, and desire to secure by Letters Patent of the United States, is

1. In a tile-ditching machine of the character described, wings or spreaders each adapted to be independently adjusted both vertically and horizontally, as set forth.
