SLOPING-BANK-GUTTING ATTACHMENT.

Application filed. February 1253, 1922. serial No. 538,52Q.

To all whom it may concern:

Be it knownthat 1, CHARLES L. Gnomes, a citizen of the United States, and a resident of Findlay, county of Hancock, and State of Ohio, have made an Invention Appertaining to a- Sloping-Bank-Cutting Attachment; and I do hereby 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 makeand use the same, reference .being had to the accompanying drawings,

and to the characters of reference marked thereon, which form a part of this specification.

This invention relates to excavating machines particularly of the digging wheel type, and has for its primary object the provision of a simple, improved and efiicient sloping bank cutting attachment therefor and a simple and compact means for mounting and driving the same.

The invention is fully described in the following specification, and while in its broader aspect it is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated. in the accompanying drawings, in which,

Fig. 1 is a side elevation of an excavating wheel and its mounting, with a sloping bank cutting attachment embodying the invention associated therewith and with a part of the wheel buckets removed. Fig.

. 2 is an end elevation thereof with the digging wheel in central cross section and with parts removed, and Fig. 3 is a fragmentary plan view of the rear end portion of the frame and associated digging and sloping wheel driving parts. I

Referring to the drawings, 1 designate the excavating wheel and 2 the frame in which it is mounted, which frame is carried for vertical adjusting movements by the machine with which associated as well understood in the art. The frame 2 has a substructure 3 which cooperates with the mainframe 2 to carry two sets of rollers 4 in rectangularly spaced relation, which rollers cooperate to guide the rotary move ments of the excavating wheel, as is common in machines of this type.

A roller 4 of each set is mounted on a shaft 5,'which is journaled over the frame 2 transversely thereof in suitable bearing brackets 6 mounted thereon, and these -when the frame is raised. This driving means is common in machines of this class and need not therefore be specifically described.

A second cross shaft 12 is journaled in the frame 2 between the two side beams thereof and is connected by a set of gears 13 to the shaft 5. The shaft 12 has a sprocket wheel 14: fixed thereto intermediate its ends and connected by a chain 15 to a sprocket wheel 16 mounted on a cross shaft 17 journaled below the sub-frame 3 in bearing brackets 18 extending down from the frame 2 at the outer sides of the frame 3.

Each bearing bracket 18 is provided at its lower end below the bearing for the shaft 17 with a bearing 19 which is inclined transversely of the wheel and hasits elevated end projecting inwardly into the opening of the adjacent side rim of the excavating wheel. A shaft 20 is journaled in each bearing 19 and has its inner elevated end in bevel-gear connection 21 with the shaft 17 and carries at its outer lower end a sloping bank cutting wheel 22. The wheels 22 are of spider form, having, in the present instance, four arms 23 radiating therefrom and each carrying 'a cutter or rooter 24 at the outer side of its outer end portion. It is evident that upon a rotation of the wheels 22 in cutting engagement with respective banks of a trench being dug'the banks will be given a sloping cut as shown in Fig. 2. It is understood that the slope cutting wheels 22 receive their power from the excavating wheel driving shaft 5.

Theshaft 17 projects at its ends over the central portions of the respective slope cutting wheels 22 and carries at each end an agitating member 25 in the form of a crossarm which revolves with the shaft 17. This member is disposed between the upper portion of the slope cutting wheel 22 and the digging wheel and acts to break up the material cut 05 the bank by the slope cutter, thereby enabling such material to be taken driving up more readily bythe buckets of the digging wheel.

The shafts 26 are for driving the side delivery aprons for the excavating material and form no part of the invention.

I wish it understood that my invention is not limited to any specific construction, arrangement or form of the parts, as it is capable of embodiment in numerous forms without departing from the spirit of the claims.

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

1. In a machine of the class described, a frame, an excavating Wheel rotatably mounted in the frame, a slope cutting wheel carried by the frame within the periphery of the excavating wheel, a rotatable agitating member disposed between the excavating wheel and the slop cutting wheel to break up the material cut by the latter, and means for driving the slope cutting wheel and agitating member.

2. In a machine of the class described, a digging wheel carrying frame, a digging wheel mounted therein, a cross shaft, a slope cutting wheel carried by the frame at a side of the lower portion thereof and having its axis outwardly and downwardly inclined, a rotatable agitating member disposed between the digging wheel and slope cutting wheel to break up th material cut by the latter, and means for driving the slope cutting wheel and agitator.

3. In a machine of the class described, a digging Wheel carrying frame, a digging wheel mounted therein, an outwardly and downwardly inclined shaft journaled in the frame at one side of the digging wheel near its lower portion, a slope cutting wheel carried by said shaft at its outer end, a cross shaft mounted in the frame over the inclined shaft, an agitating member carried by the cross shaft between the digging Wheel and slope cutting wheel to break up material cut by-the latter, driving connection be tween the two shafts, means for driving the digging wheel and driving connection between said means and the cross shaft.

In testimony whereof I have hereunto signed my name to this specification.

CHAR-LES L. GEORGE.
