Y .DITCHING MACHINE. l

' application med December 30, 1927. serial :ramasse This invention relates toV a ditching-machine, with special reference Vto the ycutting wheel and the means for driving'thesame.

In machines of the type to which my -1nvention relates, the cutting and digging members Iare carried by two wheel rims` broken, or when assembling anew machine,`

i ditliculty has been experienced in obtaining the proper relation between them in order that there may be no binding action and 1n order that thedri've mayJbe equalv at oppo-I site sides of the wheel.

equal driving relations between the two rims and the power shaft. Y I

The specific construction of the invention, in its present embodiment, together with the advantages resulting therefrom, will be more particularly described withreference to the accompanying drawing, in whichof a ditching machine'to which the invention is applied.

Fig. 2 is a sectional view'taken substantially on the line 2*, 2 of Fig.-1. 'l V Fig. 3 is a detailview of one of the driving gears and the means for mounting the same. e Y

The invention is illustrated in connection with a ditching machine having a frame 5 on which is a revolubly mounted cutting wheel having oppositely disposed rims 7. Secured to'these rims are annular strips 8 to which the cutting and digging members 9 are secured. Each rim 7 revolves on idle rolls 10, one ofk which isshown in Fig. 1. Associated with each ,rim isla driving. gear 11 meshing with cogs 12 lcarried by the rim. The driving gear is secured to a sleeve 13 mounted in a journal box 14 at the side of the frame 5. The driving sleeve 13 is provided with anges 15 and 16 at opposite sides of the journal box.

The inner portion of each sleeve 13 is noncircular in cross section, preferably square as shown in Figure 3, and 'is formedr with a The means for driving these rimsv The object of the present invention is to overcome the vabove mentioned difficultiesy and to obtain yfreely operable, uniform Yand,

Figure 1 is avside'elevation of a portionV number of peripheral channels'17 infone of which al split collar 18 is mounted, Athis collar being bolted to' the'l driving gear 11. Thus the drivlng gear is secured on the noncircuf larv portion of the shaft and held'against movement longitudinally thereof while the several channelsfl? permit the gear tov bef.

adjusted for cutting wheels of different width.

Each sleeve 4'13 isy drivenfby a sprocket',l

wheel 19 mounted on the'outer end thereof and bolted to the flange 15. A beveled gear 20 is also bolted to the flange and, through the medium of gearing 23, is adapted to drive a conveyor for carrying away the materialwhich is removed from the ditch by y the cutting wheel. 1A shaft 21 ismounted in the sleeves 13 and 'holds the sameinfaline-L ment, the shaft being retained by heads 22V secured 'to opposite vends thereof.

The

sprocket wheels 19`are driven by sprocketf chains 24 from sprocket wheelsf25 and Y26 respectively, mounted on a countershaft 27.

One of the sprocket wheels, as 2.5i, is keyed to the counter shaft 27 while the other, as 26, vis held by a retaining'washer 2K8 on Ythe shaft 27Vand in toothed engagementV with Ia sleeve 29 lwhich is rotatably 'mounted on the shaft. *Theshaft 27 andL sleeve 29,vv and consequently the sprocket wheels 25 and `26, are

differentially driven by differential gearing 30 which has a ring gear 31 driven bya sprocket chain 32 from Ythemrnain power shaft 33. j

j From the foregoingA description it will be seen that the sprocket wheels 25 and2G, and

consequently the driving gears 11, arediferentially driven, thus permitting the gears 11 to adjust themselves automatically to they cogsy l2 onthe vrims ofthe cutting wheel. This compensates for any inequalities in the rims, preventsr any binding action kdue vto unequal wear ori unequalstraln and insures a smooth and uniform' drive under. all conditlons.

vWhile I have shownfand described the invention as applied only 'to one specific type of ditching machine it is to be understood that the invention is not limited to this specific construction but may be readily modified for usein connectionv with various other types of construction.

IVhat I claim is:

1.l In a ditching machine, a cutting wheel,

having two laterally spaced annularlytoothed lil members, a drive gear inmesh With each toothed member, said gears being relatively rotatable, and differential driving means for said gears. Y i

2. In a ditching machine, a cutting Wheel comprising peripherally disposed ditching members and opposed annularly toothed members on which the ditching members are secured, drivegears meshing With the respective toothed members, said gears being relatively rotatable, A and differential means for driving vsaid gears.

Y 3. In a ditching machine, a frame," a eut-` tingwheel mounted therein, eppositely disposed rims secured tothe side edges of the wheel, a pair of .gears in driving relation te the respective rims, a pair of rotatable members on Which the respetcive driving gears are removably secured, and differential means for driving said rotatable members.

,4. In a ditching machine, a cutting Wheel having oppositely disposed rims secured to the side edges thereof, tWo axially alined rotatable members independently mounted andgeared tothe respective rims, `and differential means for driving said rotatable members. y

In a ditching machine, a cutting Wheel having oppositely disposed rims secured to the side edges thereof, a shaft parallel to the axis of the rims, a pair of sleeves mounted for independent rotation on said shaft,

gearing connecting theV sleeves individually to the respective rims, and differentialmea-ns p for rotating said sleeves.

6. In a ditching machine, a frame, a cutting Wheel mounted therein, oppositely disposed rims secured to the side edges of the Wheel, a pair of axially alined sleeves journaled in said frame, a shaft mounted in said sleeves, the sleeves being rotatable With respect to the shaft, each sleeve having a noncircular portion on which a gear is secured, each gear having an independent driving relation to the corresponding rim, difieren.l

tial gearing, and operative connections from said differential gearing to the respective sleeves.

7. In a ditching machine, a frame, a cutting Wheel mounted therein, oppositely disposed rims secured to the side edges of the Wheel, a pair of axially alined members in dependently journaled in the frame and each having a noncircular portion, `gears mounted on the noncireular portions and in driving relation to the respective rims, means for securing said gears against movement lengthwise of said noncircular portions, said means being adjustable .to accommodate the gears to cutting Wheels of different Widths, and differential means for driving saidaxially alined members.
