Specification of Letters Patent.

Patented July 9, 1918*".

Application filed October 12, 1917. Serial No, 196,244.

To alZw/wm it may concern. Be it known that I, ROBERT B. SUMMEns,

a citizen of Oknnilgee, 1n the county of Okmulgee and State of Oklahoma, have invented new and useful Improvements in D1tch1ngMach1nes,-

of which the following is a specification.

This invention relates to ditching maits ob ects, theprovision of a machine of this nature of exchines and has for one of simple and practical construction, devoid of cumbersome and intricate parts and which has a multiplicity of ad ustments.

Another object of the invention is to pro tremely which is vido in a ditching machine, a plow mounted an incllned elevator and being in advance of vertically adjustable with the elevator.

A further object of the invention consists inthe provision of a ditching machine, which by simple and easily operable means may be leveled irrespective of the inclination of the ground over which it is working.

A further object of the invention is to provide a machine especially useful in pipe lining, trenching, and the like, and having means for discharging the excavated mate- I rial adjacent to, the side of the ditch.

he invention also alms to prove ditching machines to render them more practical, useful and commercially desir-able.

With these and other objects in View, as i will become more proceeds, the 3 novel features of construction, and arrangement of parts as will be hereinapparent as the description after fully described, illustrated and claimed.

In tl 1e drawings, Figure 1 1s aside elevation of a ditching machine constructed in accordance with my 1 I .snown.

Fig. 2 is atop plan view of the machine.

*ig. 3 is a side elevation of the front half of the machine, showing the plow and conveyer in partly elevated position.

eferring in detail to the drawings by numerals, l designates as an entirety the frame of the ditching machine, said frame raving parallel side bars 2. A bolster 3extends transversely under the frame in en? gagement therewith adjacent its forward end and carries on each of its terminals a housing 4 to acconnnodate respectively the wheel standards 5. These standards are the United States, residing atgenerally im- Y invent-1011 consists in certain combination and 1s fixed on a shaft 23 extending wheels 11.

Each side bar 2 of the frame carries a forward raising and lowerlng lever 12 pivotally supported intermediate its ends by the bracket 13 on a horizontal pivot. Each lever extends longittldinally of the frame and is forward end as at pivotally connected at its of the correspond 1e upper terminal ing standard 5.

-A second pair of raising and lowering or lei cling levers 15 are pivoted to the sides 2 intermediate their ends on horizontal pivots supported by brackets 16. These levers extend longitudinally of the frame and are pivotally connected at their rear ends to the upper terminals of the standards 10 as indicated at 17. 'The inner ends of the two levers on each side of the frame terminate in spaced relation to one'another and are connected by a chain or other flexible connection 18 which latter is connected centrally of its ends to a chain 19. The chains 19 are trained over pulleys 20 carried by brackets 21 and are wound in opposite directions about a drum 22 and fixed thereon. This drum extends longitudinally of the frame The wardly to a turning arm or lever 24:.

lever may be swung from side to side to tate thedrum and may be locked in any set position by means of thelatch mechanism as The rotation of the drum winds chains 19 and unwinds chain soit will be seen thereon oneof the therefrom the other that since these chains operate upon the levers 12 and 15, that the machine may be quickly leveled.

he earth is excavated by a plow share 25 having vertical side wings 26 which taper upwardly as shown. Each and adjustably connected to a plow beam y means of a clamp 28 having a sliding engagement with the beam and adapted to be locked thereto as shown. Pivots 29 connect the lower rear corners of the plow share rebars 2 of the frame and are each 7 extends vertically through a bracket with a binding orgear to tilting levers by the latch 37.
