FODDER-CUTTER.

Specification of Letters Patent.

Patented March 31, 190s.

Application iled April 28, 1906. Serial No. 314,132. A

To all whom 'it may concern:

Be it known that I, JOSEPH DICK, a citizen of the Unit-ed States, residing at Canton, in ythe county of Stark and State of Ohio, have invented a new and useful Improvementin Fodder-Cutters, of which the following is a specific-ation.

The invention relates to certain features in the construction ofAthe outer bearing support for the main /shaft, in, machines for cutting forage. l

The/generalobjects of the invention are to provide means for mounting and supporting the outer bearing for the main shaft so that the driving belt can be applied and removed without difficulty, and for so adjusting and securing the shaft that'thel cutting knives will not be deiiectcd by the tension of the belt. These objects are attained by the constructidi, mechanism and arrangement illustrated-in the accompanying drawings, in which# i Figure 1 is a plan section of a fodder cutter showing the general arrangementof the parts and Fig. 2, a detached perspective view of the outer main shaft bearing showing fragmentary parts of its supporting bracket.

Similar numerals refer to similar parts throughout the drawings. y

The main shaft 1 is]ournaled in suitable bearings 2 and 2a axially mounted in the ends ofthe case 3, and the fans 4, and cutting knives 5 are secured to the main shaft by means of the balance disk 6 'within-the case, and the pulley 7 is secured'on theshaft in rear of the case. Power is communicated from the main shaft to the lower feed roll 8 v by Vmeans of the cog gear 9, the counter shaft 10, the clutch gear 11, the transverse shaft 12, and the sprocket gear 13;' and ower is transmitted from the lower feed rol to the*l upper feed roll (not shown) by means of the shaft 15, the cog orear 16, and the shaft 17, which latter shaft is provided with the knuckle joint 18 to accommodate the necessary vertical movements of the upper feed roll; which features of construction are common to machines` of the type used lto illustrate the improvement and, -excepting in combination, constitute no part of the present invention.

The rearward ported from below by means of the brace 20 vfree end of the main shaft is journaled in the bearing 19 which is sup which is preferably connected below to the 55 case by means of the ears 21 and the pin 22,

passed through the apertures 23 in the brace and ears; and above to the bearing by means of the ears 24 and the pin 25 passed throughx;y

Vthe apertures 26 in the ears and brace:- and the bearing 19 is sustained against lateral.

movement by means of the bracket 27 having its ends detachably connected to the case, preferably by means of the ears 28 andA pins 29 like the lower brace; which bracket is passed through theslot 30 formed in the' bearing, one corner of which slot is beveled to form theinclinedface 31 against which the corresponding edge 32 of the bracket 'is ada ted to be wedged, and the op osite edge of t e bracket is beveled to form t e inclined face33, against which face the set screw 34 in the bracket is adaptedto be turned, by which means the bracket is wed ed against the opposing inclined face of t e bear' slot whereby the' bearing is rigidly hel against lateral movement. e

When it is desired to remove the pulley 7 or the driving belt (not shown), the same can be done by removing the bearing 19, which 'is readily accomplished by removlng the con-l necting ins by means of which 'the brace and brac et are secured to the case; and if it instit on the bracket, it is only necessary to oosen the set screw 34.

Vhen the detachable bearing 19 ismounted on; the brace and bracket and the set' srew is loosened, it is evident that the bearing can be adjusted by sliding it laterally along the bracket, and that when itv has been brought into true alinement with the case bearings 2 and 2a it can be secured in this position ilby tightening the, set screw. It will be 'understood that there is sufficient flexibility inthe supporting brace, or looseness in its joints, to accommodate the slight lateral is desired to detach'the bearingfrom or admovement of the detachable bearing required.

for its adjustment. vTheadjustment of the.

detachable bearing thus described serves to brin(y the main shaft laterally into its true axia line, which is pro erly a proximately erpendicular to. the p ane o the cuttingfnives, which knives are adapted to shear against the cutter bar 35 located in one end ,oi the case. And-when the detachable'bear-4 ing is secured in this osi'tion, it is evident that the tension of the elt on' the pulley canet vone side,

bracket into t not bend or flex the sheftand thus deflect the cutting knives out of their proper p0sition with reference to the cutter-ber.

What I cleini as my invention, and desire to secure by Letters Patent, s.-

l'. In a. fodder cutter7 an axial shaft hevin e pulley thereon outside the cese', e journafl bearingfor the shaft outside the pulley,

, there being, a, transverse'slot' in the bearing having the feces tapered toward each. other e, detachable supporting brace `between 'the bearing and the cese, e lateral bracket detachebly connecte with the cese# at its ends and located in the transverse slot of the bearin with means for forcing/ the e tapered side of the slot.

2. In a fodder cutter, alcase with a cutterl'bali in one enti thereof, e shaft journaled in the cese and having cuttin knives thereon f adapted to sheer against t e cutter ber, e pulley' on the shaft outside the case, a bearing, for the shaft outside the pulley, a supporting brace end e bracket for the bearing connected with the case, and means for ad- )listing and securi g the bearing on' the brace end bracket. Y

In testimony whereof I have signed my neme to this specieetion in the presence of' ltwo subscribing witnesses` i l JOSEPH DICK.
