This invention relates to excavators of the full-revolving, type. V vI The general purpose offthe invention is to provide interengaging means on the re volving deck. and the table or support upon of engagement but, upon a heavy load being applied'to the deck, willengage with, nonv 'sisted by thesupporting table and the two-- ,tor or other vehicle carrying thesame, the
gibs frictionally engaging *the flange onlyv accompanying drawings and described berolling friction to prevent 't'eetering'of the deckon the turntable during lexcavating operations thereby holdingtheline of the cut accurately and'which', particularly in skimming roadways, hold the'scoop to the grade and furthermore relieve the center pin on which the shovel pivots of severe upon a heavy load "being appliedto the deck as when'crowdingthe scoop of the ex cavator. v r i The foregoing and other objects are ob-' tained bythe construction illustrated in the It is" to be understood'thatthe invention is not limited to the specific form thereof shown and described. I J 3 Of the accompanying drawings, Figurel l is a side elevation of an excavator embodying the invention, two types of excavating attachments being indicated thereon in dotted lines; and
Figure 2 is a section "on line of Figure 1.v
Referring to the 10 designates a tractor and 11 an annular or circular table mounted thereon onwhich is supported a revolving deck 12 pivoting on a center pin 13. i 1 r The table-11 has al'ateral flange -l1 ..thereon and at circumferentially spaced pointson the under side of de'ck12 are gibs 14;, 1 4
drawings, the numeral embracing the flange 1 1%, but normally out of engagement therewith. 1
At 15 there is indicated in dottedlines a skimmer attachment which, incrowding into the earth, produces a toggle action'on the deck 12 tending to lift'the front end upwardly; The gibs 14 engaging flange 11 will, accordingly, be engaged with the flange andwill tend to lift the whole forward end of thetractor 10 oifthe ground. This great weight ona leverage thelength of the whole tractor oflers such resistance to the lifting action of the skimmer 15 as to prevent its 1 definite grade can be maintained. I I
At 16 there is indicated in dotted lines an excavator attachment of the ditcher type, the dipper stickbeing shown at 17. thrust in this stick is upwardly and-also tends to lift the'forward end of deck 12, gibs 14: effectively preventing such action assuming a different angle than that at which it is initially crowded and thus a 6.5
The
and thus assisting in maintaining a definite depth of cut. 7
I The gibs 14, being normally'out of engagement with flange ll ofl'er no fric-\ tional resistance whatever to the normal rotation or sw nging of therde'ck as for dumping the scoop, but are only brought into play, 1
during a crowding action of the scoop.
It will be understood that theogibs 14 have similarbeneficial results whenother types of excavator attachments than are shown herein are used on deck 12. It will also be apparent that modifications of the invention may be resorted to withoutdepa'rting What'is claimed is: 1
An excavator of thefull-revolving type, comprising a vehicle,a circular table on'the vehicle, a 'revolving vdeck bearing on'zthe table, a pivot for the revolving deck on the from the spirit thereof or the scope of the p w 7' qap'pended claim. l
vehicle. at the centerr of the table, a lateral flange on the edge of the table, circumferentially spaced non-rotatable gibs on the under ii side of the deck extending under'the flange and normally out of engagement therewith but adapted to engage under the flange with non-rolling friction when a heavy load is applied to the deck to preveht'teetering and sideplay thereof and an excavator attachment on the forward end of the deck,
' including a boom tending to lift the forward end of the deck during an excavating operation."
