Application filed m 2, 1916.: Serial No. 94.939.

slioi'tsville, in the county ofjOnta'riov and. State of New York, have. invented certain new and useful Improvements in. .Rotary Cutting-Wheels, ofrwhich thefollowing is a. specification,.reference being had therein.

to the accompanying. drawing.

Thisinvention relates to certain. new and in rotary cuttlng.

useful improvements wheels used in .ens1lage;cutters,-the ob ec.t being to provide a cuttmg wheel wh1ch1s so constructed that theknivesnarried there by will ,be' prevented from becoming choked by. the material. being cut, meansbeing provided in connection with a the knife supports.

for allowing the material to, pass under the knives. I

Anotherobject of my invention to pro-i vide a cuttingwheel with'anoffset-portion forming a recess underthe knife supports having an inclined bottom which allows the materialfcutbythe. knives to pass under;

the same between the knife supports, therewhen cutting certain. kinds of material.

Another and further object of theinventionis to provide a. cutting Wheel which is.

provided with .stopsforl the knife Supports soas'to relieve the bolts from the thrustof- ,Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

In the drawingf I Figure-1, isa plan view of aportion of a wheel constructed in accordance withmy invention showing one of the cutting knives mounted upon a pair-.ofsupports; and

1 of; course, understood that-the wheel will Specification of Letters Patent.

be constructed at each blade, as shownin thev segments. illustrated'in Figs. 1 'and'2, the construction of which will be hereinafter fully described. 1

airranged on the face of the cutting wheel I at equal distances, is a cutting blade .2

mounted uponsupports" 3 in substantially the same manner as-shown in mycompanion case, with the exception that the supports are provided with bosses 4. fittingin recesses 5 formed; inthe faceof the wheelisurrounding the securing bolt' ;6; as. clearly shown in. Fig. 2, "which receives the end 1;

thrustof the support EIIlCl'jlILOfClGP to-provide additional means fort-his purpose the. face. of the wheel is provided. with a h1g7. ateach: support.

The supports 3-are secured in positionupon the wheel and are ad usted *m a similar manner to that disclosed. in'my companion case, abovereferredto. 3 In order to preventithe material .being cut by the-knives 2 -from.,wedging-under the knives and chokingthe cutting wheel when in-operation,,': I provide the wheel with an offset portion?) which forms arecess 9 under thespaced supportsr3,lsaid recesshaving a1 tapering or inclined bottom: 10 :terminating flushawith the faceofithe'wheel,at.11 and an inclined wall 12' terminatingat the 1 face of the wheel to the rear of the .cuttingiblade."

As the material is cut by the-knife 2 when the wheel-is being'rotated, in cutting certain" kinds of mat'erial, the @material wedges under the knife and the face of the wheel so as to choke'the cutting wheel and I have found that by providing a cutting wheeluwith an .inclineclI recess extending fromapoint-approximately in line'with the. cutting edgeof theknife, to the rear? of the cutting, knife, the cutmaterial will passbetween the knifeand wheel without wedging, thereby preventing the cutting wheel from being; choked. M IVhile I have-shown a recess constructe in a particular mannerinorder to prevent the knivesof. thewheel from becoming choked by thematerial being cut, I do not wish to limit myself to the exact construction of recess shown, as theobject of my invention is to provide means for prevent= ing' the material from accumulating under thefknife by providing the" wheel with a recess which can be formed of various shapes without departing from the spirit of my invention.

In cutter wheels of this character used in connection with ensilage cutters, the knives are set at an angle in respect'to the face of the cutting wheel so that the material is wedged under the knife and the face of the wheel as the cutting edge of the knife is at a greater distance from the face of the wheel than the rear edge of the knife and I have found that by providing the face of the wheel with a recess having an inclined bottom under the knife ex-'- tending from the cutting edge to the rear of the knife, that the distance between the knife and the bottom of the recess is gradually increased as the material is forced under the same so as to prevent the wedging action, whereby a self-clearance is obtained.

It will be seen that I have provided a cuttingwheel for an ensilage cutter with the recess arranged between the supports and to each side thereof in order to provide an ensilage cutter with a self clearing knife so as to prevent the material being cut from wedging under the knife, and while in the drawing I have shown this'recess formed of such a size that it extends out to each side of the knife, I do not wish to limit myself to the size of recess employed as in some cases it might be found that a recess located solely between the supports willaccomplish the desired result.

From the foregoing description, it will be seen that I have provided a cutting wheel for an ensilage cutter of a series of tangentially arranged cutting knives mountupon spaced supports over recesses'formed in thecutting wheel in order to allow the material being cut by the knives to pass under the knives.

I claim: a
