-To all 'whom it may concern:

Be it known that l, JOSEPH Dion, a citin zen of the United States, residing at Can ton, in the county of Stark and State of Ohio, have invented certain newand useful Improvements-iii loddenCutters, of which the following is a specication.

The invention relates to, machines for cutting forage; and the improvements pertain to the construction ot the pneumatic blower case in which the cutting-knife and the blower-fan ly Wheel is rotatably mounted, to the construction of' the feed rolls, to the devices for cleaning the feed-roll teeth and for forming a throat between the feed-rolls and the cutter-bar, and to the mechanism for adjust-ing, the upper feed roll.

A Well-known construction of the blower case is to join two separate circular side plates with a series of overlapping interchangeable peripheral plates by means of adjustable peripheral rds, the inner sides of the peripheral plates being provided with grooves'adapted to receive the edges'ot the side plates. As suoli separate side and peH ripheral plates harefrequently been made ot cast iron, it has been tound practically ini-- possible to construct and assemble the parts so that the joints will be tightly closed and dust-proof, which difticulty arises largely by reason of the rigidity of the respdotive parts, and the practical impossibility (of forming or finishing the abutting` parts toexactly lit Aeach other in all positions of relativo ar-y rangement. This difficulty is overcome by making the peripheral part of thenblower out of one or inore sheet metal sections hav ing annular corrugations in their edges adapted to tit over the edges of the side plates, with suitable devices whereby the sheet metal sections are clampedv around the side plates, inwhich relation ot the parts the resilience of the sheet metal permits the same to neatly fit and clamp .the edges of the plates at all points irrespective of any ordinary inequalities inthe finish thereof,

Fodder cutters are utilized to reduce so many kinds o't forage and other materials and to do the Work under such trying` oonditions, that it has been found desir-@ble to' make the feed rolls with a series ot annular row's ot4 teeth. thereon quite close 'together and arranged so that the teeth ot therows on one roll will mesh between the teeth of rows on the other roll Whei :he two rolls are brought near together. Difficulty has been experienced in providing means for cleining:

the teeth of Vsuch rolls to prevent the l 'from being carried around the rolls and clogging; the machine; and when piatcs have been employed to `bridge the. interval between the lower roll and the cutter diliticulty has occurred by reason oi the 'friction of the plates on the roll and of the clogging of the forage against the cutter bar on sides and unf neatlu such plateM These ditiiculties are wercoine by provini ries of preferably adjusta e clcr gers between. the iespecti l and extending the saine tir-ward toy forni a throatteriniiiatin over and. adjacent to the cutter bar. each cleaning; finger heirl ,p erably independently supported so that it will not bear either upon the roll or upon the cutter barw ln the larger fodder cutters, it has generally been found desirable 'to provide a car-y riage for the upper roller which will not only permit .it to move upward and donnward but to tilt somewhat in its lateral. pusition to accommodate the varying tlfiioltness ot' the forage, but in thesn aller'nnicliiir and especially when the for arrar in uniform bundles for teedin chine, and furthermore when i rolls 'formed with teeth and sup'iilenientcd by cleaning' lingers as herein set forth., this tilting adjustment is not essential, and itis soi'netimes more irriportant that the rolls shall be irinly preseiited to cach other in parallel relation andthat 'the upper roll can f be conveniently raised troni the lower roll Whenever it is desired to have access te the throat ot the machine. These obje ts are atn tained by suspending' the upper 'feed roll from a spring-miuroiled bracket or traine and to provide a, handle by which the saine. can be readily rotated by manual means to raise the roll..

The various objects of the invention.,

which are thus set forth in general terms,-

are attained by the' construction', mecha nisin and arrangement illustrated in the accompanying drawings, forming part here spective view of the tion or the endet' the part thereof showing the feed rolls and the lower portion ofv the adjacent cose; Fig. 3, ey vertical section of the blower cese, transverse its exis; Fig. ya detached elevator pipe coup ing showingenly one arm of the pipe bracket; Fig 5B e detached perspective View: of the ordinary peripheral bend couplinr; Fig: G, e fragmentary sectional view il ustretrng one peripherel edge joint of the cese; a detached sectional View o t' the feed transverse their' axes, showing ajznodiiied form of the throat cleaning lingers; Fig. 8, a fragmentary sectional view of one end of the lower feed roll onlline 8-8, Fig; 73' Fig; 9,' a plan viewvof. the upper feed roll supportingl bracket; Fig; 10, e sectional elevathe bridge plate appliedthe'reto; Fig. 11,11 detached W* perspective view' plate; und Fig. l2, a, cross section of the feed trough on line 12--12, FiglO.

Similar numerals refer to similar parts throughout the drawings. `VThe blower case is composed of the two side plates 1 and l, and e, sheet metal periphernl bend which is ineterablyl nitide in two sections 2 fend 2n ioined togetherV by the hinge brackets `3 and 3a and 'the pipe brackets /land fle, The peripheral edges of the side plates are`tormed with thev middle -lat :tace 5 and the lateral beveled faces 6,

and the edges of the peripheral bend sections are curved to form the corrugations 7 which. ere mede of such o cross section that they must be sprung or expanded to lit' the beveled feces of the edgesy es shown 1in Fig. ,6; and the middle'portion of the peripheral bend is preferably crowned or erched'but- Ward in its cross section, to givethe band as i o Whole some lateral as well as longitudinal elasticity, es shown in lligufg.

The' peripherel bend 4is though not' necessarily medeintwo sections, and the lower or mein section 2 preferably embraces more than heli.' of the loiver portion of the side plates, so that when placed around the plates -it will be. retained 'thereon by the spring of: the metal. Thesetivo. sections4 are coupled together by the hinge breclfets 3 nud which ere riv` eted to the respective adjacent ends7 and the 'hinge bearings are preferably mede in the form ci' the hooks 8 end 8 Whiohnre adeptto 'engage over the hinge pinlzle 9 by nielus oi which the peripheral sections orc readily .engaged and disengaged.

The elornpingboltsl, one oneacb side, connect the brackets 4tend 4 of the pipe coupling, and when the parts' are assembledthese'bolts are adapted to engage the ears 13a and 13b tightly clamp the peripheral ben-d' sections arouudthe edges of the side plates, In so doing the edge corrugetions of thebend sections are sprung orfexpended to tand clamp the beveled ed es of. the plates, and the resiliencei the and-sections permits them to t tightly against the edges of the plates at all points in their peripheral edges, thereby melting a, neet which pipe is also riveted' section, thus .making o close joint on the coupling brackets and to v and tightjoint therewith. The Apipe bracket sections `are ,provided With the grooves'- i4 and le the Walls of which are adapted to tit over end clamp the peripherol edges of the oornpletlng the peripheral closure of the cose; end the lapping of the .bandsection lirder 'the opposite hinge-section and of the one pipe bracket under the other side plates, thus :1 'substantially dustLtight cese. lt is evident that the discharge pipe can be adjusted to various positions by merely loosening the 'clamping bolts and that the lid section con e-lopened up and detached by removing the' o ts.

lly this arrangement, the wheel can be clelicotely balanced by adding one or more sheets in the. various fan apertures es may be reuired; and by utilizingthe location of the ons :it and outside the periphery of the Wheel Jfor this purpose, the ed'ectiveness of the counterholnncing Weights is increased.

Finch series ot' cylinrlric sectors 2l mounted on the respective shafts 22 and 22 by'mezinsiof the intervening collars 2l,- to vwhich collars the feed roll is preterebly mede of a i :forward ed es 2C and 26H oi the teeth are n n n n ,y n e vprerersrbly curved to facihtate their witndrawai from the forage. One cleaningr tinger 27 or 27 1s located between each row of teeth, on the side of the roll which is pre-V sented to theopposingroll,andinthe oit the lower roll each linger 2'? is curved down- 'ard aronnd thelorward side ol? the cylindric body of the roll to a pivotal bearing on the transversely lmounted' har 25, located below vthe forward side of the roll and eX- tending between and secured to the side platesA 29 of the machine frame; v and the other ends of the lower lingen' are extended rearward from the upper side of ithe roll' and after spanning' the interval between the roll and the adjacent cutter bar-'30, terroinate above but not in contact with the cntter haar, the lower edge 3l of the rear endet the finger beingr preferably beveled to reduce the thickness of the extreme end of the finger. i

The rear ends of the lower fingers snp ported on the legs 32 which may be either -pivotally riveted to the fingers as at in Fig. 2, or formed integral therewith. as shown in the modified forni in Fig. The lowerl ends of these legs are normally snpportcd on the transverse bar 34 which efr-- tends between and is secured to the side plates 29, which bar passes through the slotted ends 35 of the legs, which slots are so shaped that the respective fingers and legs can be slightly oscillated on the pivotal rods 28. The lower ngers are located and snpported so that they' do not touch or rest on the cyiindri-c body of the roll or the cutter bar at any time, which prevents any frictional contactwlth the roll and any clogging of the forage around the forward ends of the fingers and. against the rear end ol" the 'cutter bar.

The location of the fingers on each side of the feedl roll teeth serves an abut ment to hold the forage while the teeth are being withdrawn from the sain l.; and ihr-thernlore, the lower fingers, taken tngetl'ier, form a table which spans the interval between the lower feed rollend thel coltefr bar, on which table the forage travels over this interval. it 1s evident that inv event any forage drops down between or around the ends of the invers and back of the cutter liar it will be h, a

carried along and will slip over the ends of the fingers, which saine are free to be .slightly elevatedto increase the space between the lingers and the 'cutter bar it' the same is necessary, Therngers 2,27 of the upper feed roll are similarly shaped and inversely positioned,

the 'Jrward ends lle-ing carved upward @fi/fiore around the 'torvv'artl side of the cylindric body ot' the roll and are pivot-ally suspended from the transverse bar 28 located above the forward side oLt the roll and extending. between and secoredto the depending linlt plates Elli in which the bearings as 3'? for the opper 'eed roll are 'formed or secured; and. the torward'ends of the upper fingers are suspended by the legs 32l from the transverse rod Sala by means of the slotted ends 35S which are shaped so that the legs are adapted lo be oscillated on the pivot har. The fingers of the upper feed roll like the lingers ot' the lower roll serveias an abntnient for the forage when the 'teeth of. the opper roll are being); withdrawn theietroi'n; and the iorward ends of the opper fingers are extended torwardzmd terminate above the forwa rd ends of the lower lingers.

rIlle series ot lingers above and below, taken together forni the-opper and lower walls out' a throat through which the forage is guided freni the feed rolls to the cutter bar. And it is evident that as each linger is adapted to osciliate independently of the other, the upper fingers are adapte-d to be slightly elevated to accommodate the varying thickness ot' the forage between the rolls and that this elevation is not necessarily roede by alhfthe iingers at the same time but adapts itself to the varying thickness of the forage in'ditierent portions of its width. The upper fingers, .like the lower ones, are so mounted that they do not at any 'time come in Contact with the cylindric body of the roll so that there never any lirictional contact therewith.

ln the modified torni of the lingers 2lb and 27@ which is shown in F 'Y thesnpporting-and suspending legs 82 and 32 are inadeinteg'ral with the lingers, and in the Samej'lgure'the upward oscillation of thev fingers is indicated in breiten lines; and it. will be understood that. it is not essential to provide slotted supports 'for' the rear ends of the" lingers,J although the slight oscillas tion of the lingers thereby permitted isvery desirable'for the purposes. which have been mentioned. some of the benefits ot the lower lingers can be realized without the use of the upper fingers, but the presenccoi' the upper fingers is preferred to clean thewppcr teeth and to form the throat between the 'feed rolls and the cutter ba'r,- which throat is specially de sirahie when vtine and light materials are being t'ed into the n'lachine.
