ROBERT A. BAYLES, 0F STOCKTON, CALI'FOR/NIA.

nXcAvATrNs-MACHINE.

Specification of Letters Patent.

Patented Apr. 6, 1920.

Application led March 25, 1919. Serial No. 285,040.

To all lwhom z't may concern:

Be it known that I, ROBERT A. BAYLES, a citizen of the. United States of America, residing at Stockton, in the county of San Joaquin, State of California, have invented certain new and useful Improvements in Excavating-Machines; and I do declare the following to be a clear, full, and exact description of the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this application.

This invention relates to improvements in excavating machines, and particularly to a type adapted to excavate and dig ditches and lthe like; the principal object of the invention being to produce a machine which frame, or 4the depth at whichthe,v plowing can be used to dig a ditch of any depth or width, and which will deposit the dirt so excavated off to one side of the ditch, leaving a furrow or ditch clean of loose earth.

A further object has been to produce a machine which will be simple of operation and yet extremely eiicient for the purpose for which it is designed.

These objects, I accomplish by means of such structure and relative arrangement of the parts as will fully appear by a perusal of the following specification and claims.

On the drawings, similar characters of reference indicate corresponding parts in the several views.

Figure 1 is a side elevation of my improved excavator with the earth on one side of the ditch being dug cut away.

Fig. 2 is a similar view, taken on the opposite side of the machine.

Fig. 3 is a cross sectional view, taken relatively on a line 3 3 of Fig. 1.

Fig. 4 is a fragmentary view of a plow adjustment'means taken on a line 4-4 of Fig. 1.

Referring now more particularly to the numerals of reference on the drawings, the numeral 1 represents a pair of spaced and suitably connected longitudinal frames, between vvhich is journaled a large wide face wheel 2 having spokes 3 on one side of the same. From this side a frusto-conical ring 4 extends inwardly, forming a V-shaped pocket 5 all around the inner periphery of the wheel 2 adjacent the side having the spokes 3 thereon. This pocket s subdivided by a plurality of vanes or plates 6 suitably spaced around the wheel and extending from the side of the wheel opposite to the spokes to the ring 4 and being connected thereto.

Positionedon the latter side ,of the wheel and flexibly mounted to the frame 1 is a plow beam 7 having a plow share 8 secured to the same in such a manner that the dirt turned up thereby will be deposited in the pockets 5 of the wheel 2.

The pulling strain on the' plow beamis taken by a chain 9 secured thereto at the forward end and to a swingle or double tree 10 mounted for vertical. yadjustment relative VIAto the frame 'l by means ofa slotted bar 11, which member 10 is adapted to be Nhitched up, with draft animalsv to pull the excavator. v Y

The angle of the plowA relativeto ythe is to be done relative to the wheel 2 is regulated at the forward end by means of a chain l2, adapted to be wound on aV shaft 13 by some such meansy as a worm drive 14 operated by a hand wheel 15 from the drivers seat 16 at the rear ofthe excavator. vThe rear end of the plow 'is held in adjustablev position by means of a rectangular bar meni` ber' 17 'pivotally mounted4 thereto, one'side of which is slotted as at 18 and adjustably secured to the frame'through such slot.

Positioned in the wheel 2 above the center thereof isa hopper 19 rigidly mounted to the frame 1, which hopper is adapted to discharge onto a short endless conveyer belt 20, whose outer end is adjustable for height at its forward end as shown at 21. This conveyer discharges onto a conveyer 22, of a length suflicient to discharge its contents aV considerable distance from the machine, the outer end being adjustable as to height and being so adjusted and held by means of a chain 23 adapted to be let out or drawn up by means of a hand wheel mechanism 24 near the seat 16.

Both conveyers are chain driven, such driving means being transmitted through bevel gears 25, which are driven with the rotation of the wheel 2 by means'of a' chain 26 on a sprocket 27 'on the wheel 2. The upwardly riding side of the wheel 2 above the center thereof and to the hopper 19 has a curved plate 28 `following the inner periphery of the ring 4 and extending across the face of the wheel in order that the dirt in the pockets will be retained therein yuntil the hopper 19 is reached.

The rear end of the eXcavator is supported by a wheel 29 adjustable for height by any suitable means such as the ratchet-held lever 30. v

Side balance for the machine is had by means of a wheel 31, set on an offset shaft 32 adapted to be clamped in any desired position in the bearing 33, which is adapted to be clamped at any desired point to abeam 34C extending at right angles from the frame l on the side opposite to the conveyer and plow mechanisms. This wheel is adapted to rest on the bank of the ditch which is being dug to balance the machine, but the offset portion of the shaft 32 is of sufficient length to enable the wheel 3l to ride on the vground at the same level as the wheel 2 when the machine is being moved over even ground. In the operation of the machine, the plow 1s first lowered a certain distance below the level of Vthe wheel 2 by means of the 'forward and rear adjustments in order to make the initial cuts in the ground.

The Wheel 2 then rides in these cuts, and the plow is operated to cut a furrow alongside to the desired depth, the operation being repeated back and forth until the desired width and depth of ditch has been attained. The dirt from the plow is emptied into the pockets 5 in the wheel, and this dirt is then discharged into the hopper 19 and deposited to one side of the machine by the conveyer 22. n

Thus, from the foregoing description 'it will readily be seen that I have produced such a device as substantially fulfils the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice, such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.

Having thus described my invention, what I claim as new and useful and desire to secure by Letters Patent is l. An excavator comprising a frame, a wide faced wheel mounted therein, a plow positioned adjacent one side of the wheel, a balance wheel on the opposite side of the first named wheel, and means whereby the balance wheel may be adjusted both for height and transverse distance relative to the first named wheel.

2. In an excavator having a frame, a wide faced wheel mounted therein and a balance wheel on one side thereof, means whereby the balance wheel may be y adjusted both for height and transverse distance relative to the first named wheel, suchmeans including a beam proj ecting from the frame at right angles thereto, a carriage adjustably mounted to the beaml for longitudinal movement relative thereto, and a shaft extending parallel to the beam and adjustably clamped to the carriage against turning movement relative thereto, the shaft having an extension thereon beyond the carriage at right angles to the beam, the balance wheel being mounted on this extension and parallel thereto.

In testimony whereof I affiX'my signature in presence of two witnesses.
