9 Claims.

'I'he invention relates to a ditching machine and more especially to an apparatus for making ditches and cleaning the same, especially those in irrigated districts.

The primary object of the invention is the provision of a machine of this character, wherein a at bottom ditch can be completed in a single operation or in the advancing ofthe machine in one direction and also that will ride level and require but little effort to keep the same in a straight and level path.

Another object of the invention is the provision of a machine of this character, wherein the construction thereof is such as to enable the cleaning of irrigating ditches and the tractor with which it is used may be kept clear of the ditch and such machine will stay fiat in the ditch even when subjected to side draft.

A further object of the invention is the provision of a machine of this character, wherein it is susceptible of a wide range of adjustment and will operate for the making of a ditch or the cleaning thereof and in the operation will level the banks at opposite sides of the ditch.

A still further object of the invention is the provision of a machine of this character, which is extremely simple in its construction, thoroughly reliable and eiiicient in its operation, convenient for use, strong, durable, and inexpensive to manufacture.

With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings, which disclose the prefered embodiment of the invention and pointed out in the claims hereunto appended.

yIn the accompanying drawings:

Figure 1 is a top plan view of the machine constructed in accordance with the invention.

Figure 2 is a side elevation thereof partly broken away.

Figure 3 is a rear elevation.

Figure 4 is a fragmentary rear elevation showing an adjustment of the machine.

Figure 5 is a top plan view partly broken away and showing an adjustment of the hitch.

Figure 6 is a sectional View on the line 6 6 of Figure 5 looking in the direction of the arrows.

Figure 7 is a. sectional view on the line 1-1 of Figure 6 looking in the direction of the arrows.

Figure 8 is a fragmentary detailed side elevation.

Figure 9 is a fragmentary side elevation of one of the mould plates.

Figure 10 is a sectional view on the line Ill-I0 of Figure 4.

Figure 11 is a fragmentary elevation showing a bank leveling wing.

Figure 12 is a sectional view on the line I2--I2 of Figure 11 looking in the direction of the arrows.

Similar reference characters indicate corresponding parts throughout the several viewsY in the drawings.

Referring to thel drawings in detail, the machine in its preferred embodiment comprises a plow share or member Ill made secure in any suitable manner to the forwardly converging front runner sections I'l which are connected by hinges I2 rearwardly of the share or member I0 and also connected by hinges I3 to the rear runner sections I4 these being preferably arranged in spaced parallel relation to each other and are in the form of U-irons. The sections II at their outer sides have riveted or otherwise secured thereto mould plates I5 these carrying at their lower ends outwardly curled scraping cutter blades I6. Connected with the rear ends of the mould plates I5 by hinges I1 are substantially segmental shaped leaves I8 to which are pivoted at I9 vertical swinging rear mould plates 20 these having at their lowermost edges scraper or cutter blades 2| which are curled outwardly similar to the blades It. The leaves I'8 and the mould plates 20 are provided with matching apertures 22 for accommodating detachable fasteners 23 so that the plates 20 can be made secure in vertically adjusted position or secured to operate in the same plane with the plates I5. The plates 20 have the outturned upper edges 24 and each is also provided with a clearance slot 25 for the companion leaf I8 so that there will be no interference in the vertical upward swing of the plate 2U on adjustment thereof.

The rear runners I4 carry fore and aft thereof channeled brackets 26 with which are fitted adjustable tie plates 21, these being provided with apertures 28 and the brackets with the apertures 29 as companions thereto for accommodating fasteners 30 for the adjustable coupling of the plates 2'I with said brackets and in this fashion the runners may be disposed at the desired distance apart for regulating the spread of the ditching machine.

The mould plates 2U carry eyes 3| engaged by links 32 these being engaged with adjustable eyes 33 mounted in the brackets 26 rearmost of the runners I4. These links have fitted therewith adjustable slides 34 to which are pivoted braces which are connected with the eyes 36 on the plates I8 and elevated with relation to the eyes 3|. The slides 34 are fitted with set screws 31 for securing the same adjusted on the links 32.

At the front of the machine is carried a vertical hitch 38 for a tractor or other draft machinery.

In Figure 5 of the drawings the machine at the front has connected therewith the horizontally arranged hitch 39 for side draft purposes.

Connected with the rear ends of the plates 20 by hinges 40 are bank scraping wings 4|, each plate 20.

At the rear ends of the runners I4 are pivotally supported equalizer members r43 which function as calks to steady the machine thereof as will be apparent from Figures 2, 3 and 4 of the drawings.

It will appear that the machine can be adjusted for lateral spread thereof and alsothe mould plates 20 can be vertically adjusted so `as to have the wings 4| scrape and levelthebanks at opposite sides of a ditch as formed by the machine or as cleaned thereby.

If found desirable, the inner runners |4 instead of being pivoted for lateral swing,-as at I3, they may be made rigid and maintained in parallel relation to each other, this being optional.`
