Specification of Letters Patent.

Application filed February 21, 191 9. Serial No. 278,455.
. is a specification.
This invention relates to excavating machinery and particularly to ditching machines. I
An object of this invention is to produce novel means for holding the sides of ditches against disintegration or caving While the earth removing mechanism is being operated, and furthermore, to provide novel means whereby the sides of a ditch may be operated 011 and dislodged for the purpose of widening the cut-or ditch as the scooping at the bottom of the ditch progresses.
A further object of this invention is to produce earth displacing mechanism operatinglaterally of the ditch during a predetermined interval of its travel longitudinally of the ditch, novel means being also supplied for rendering the said displacing mechanism inactive or inoperative during another interval of its travel, and particularly to move the displacing mechanism laterally when traveling along that part of the ditch containing the shield.
A still further object of the invention is to provide novel means whereby the shield and excavating mechanism are assembled to move in unison along a ditch, novel means being present for bracing the shields at the sides and holding them firmly againstthe walls of the excavation.
lVith the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.
In describing the invention in detail, reference will be had to the accompanying drawings forming part of this specification, wherein like characters denote corresponding parts in the several views, and in which- Figure 1 illustrates a side elevation of a fragment of the device, the rear wall of the shield being in section;
Fig. 2 illustrates a top plan view of a fragment of the excavating apparatus on an enlarged scale;
Fig. 3 illustrates a sectional view on the line 33 of Fig. 4:;
Fig. 4: illustrates a transve view of the trench side scraper;
Fig; 5 illustrates a sectional view of a fragment of the sheathing showing a brace in elevation; and
Fig. 6 illustrates a sectional view of the casing on a reduced scale.
In these drawings 10 denotes a, frame of an excavator of any appropriate type for digging ditches, the same including ordinary sprocket chains, excavating and conveying buckets 12, and any appropriate power transmitting means (not shown).
There is of course a plurality of excavating and conveying buckets and preferably alternating therewith, there are side scraping or cutting devices, attached to the chains and carried thereby.
each comprises an inner plate or yoke 12, havmg curved slots 13 and 14; the sald yoke being connected to the links of the chains 11 by posts 15 attached to the yoke by welding or fasteners (not shown), which fastenings may comprise rivets, bolts or the like.
rse sectional In the present embodlment of the side scrapers or cutters,
The shield on each side comprises a series of plates :29 having their edges secured together by rivets 30 or the like and the said plates have a series of bases 81 secured to them by fastenings such as shown at 3'2, the said bases constituting abutments for the braces 33 Which hold the sides of the shield in spaced relation and force the said sides of the shield against the side of the excavation so as to prevent dislodgment of the earth. The braces 83 are of a type Which comprise two telescopic sections 34 and 35 screw threaded so that the sections may be extended or retracted to increase or diminish the pressure on the sides of the shield.
By reason. of the employment of the in.- vention described, the ditching machines now in common use can be employed in any kind of soil While at the same time the sides of the ditch'vvill be held against caving so that the idea of the attachment is to convert a regular ditching machine andL provide it With a shield bolted to the ditcher on each side, the said shield following in a path made for it by the clearance afforded, lue to the operation of the laterally extending arms and the blades carried by them.
The present invention, that is to say, the attachment Which is applied to ordinary ditching machines is not intended to operate to increase the depth of a ditch, but is simply intended to Widen the ditch by removing some of the sides to create a clearance, as stated, for the shield. The regular bucket ditching machines now in common use out the depth of the ditch and carry out the soil so that the main idea included in this invention is that of the side cutting ele ments and the shield which may be used in connection with any ditching machine. The braces for holding the sides and shield in spaced relation are also important features of the invention.
On the front end of the shield there is a diagonally disposed plate 36 on each side, made separate from the main parts of the sides of the shield, so that they may be at tached to the sides of the shield by bolts 37 to adjust the end plate in different positions on the ditching boom to allow for the removal of rocks from in front of the boom,
and the holes 38 permit the bolt to be adjusted for the purpose stated.
The rear end of the steel boom may be used opened or closed and When closed, the ditch may be filled directly, behind it, it being seen that the rear Wall 88 has a flange 39, one of which will, of course, be supplied on each end of the Wall, so that it may be attached by bolts 40 or the like to the sides of the shield.
l clain 1. In a ditching machine, a chain having excm'ating and conveying buckets thereon adapted to excavate and remove earth, members carried by the chain and extending laterally thereof, means on said members for ren'ioving earth from th sides of a ditch, and means for retracting the last mentioned members.
2. In an excavating machine, excavating buckets, means for moving the said buckets whereby they operate to remove ear h, members interposed between the said first mentioned members and operative to remove earth from the sides of the cut created by the first mentioned members, means for holding the second mentioned members in operative position, and means for retracting the said members. 7 l
3. In an excavating machine, a frame, excavating and conveying members, means for carrying the excavating and conveying members with rela ion to the frame and shield, a shield carried by the frame, means for holding the parts of the shield in operative positions, means for removing the sides of the excavation, means movable with the first mentioned members for removing the sides of the excavation and means for retracting sain members when they pass the shield.
