rlhis invention relates to ensilage machines.

ln ensilage machines as heretofore constructed, it has been the usual, practice to have an indirect drive ior the blower and in the itew instances in which the blower is mounted upon the cutter shalt it has been the usual practice to provide an auxiliary Mleed or auger for passing the material to the blower.

Further these machines have either-'i reqquired an excessive amount ol" power or else have tailed to give lull satisfaction d ne to the :tact that the iteed spout vlrerpiently clogged.

Further than this in certain types oit niachines the blower has been so constructed that it produced a number ol? eddy air currents which caused whirling and unnecessarily consumed power.

',lhis invention is designed to overcome the defects noted above and objects oi such invention are to provide a novellorni olf ensilage machine in which the blower and cut ter are directly connected and in which a novel form oil ileed spout is associated with these two devices and is very short and so constructed 'that no auxiliary :feed is needed and yet in which the possibi lityoli clogging is wholly avoided together with any unnecessary eddy air currents.

Further objects are to provide a novel form of ensilage machine in which a cylinder type out cutter is directly connected to the blower and in which the leed spout is so constructed and associated with these parts that a film ot air or layer ol air travels inwardly beneath the cut material, and in addition a current ol air travels directly through the leed spout, the leed spout itself being relatively slnall at all points and extremely short, such "leed spout opening into the blower at a point intermediate its center and periphery and below the delivery chute.

This invention has for its further object the provision ot a very shallow :teed spout immediately under the knives and constructed to talie air at such point and to converge to a substantially circular opening in the blower casing so that the feed spout has relatively small cross section at all points and a relatively small opening into the blower or :tan casing, thus causing the feed to travel `with the least deflection :from its natural course.

Further objects are 'to provide an ensilage machine which is highly etlicient and which is ol eminently practical construction.

`the lorward end oif the main casing 2.

An embodiment ol the invention is shown in the accompanying drawings, in which z-f Figure l is a side view ol the machine.

Figure 2 is a sectional view through the blower, such view correspondingr to a section on the .line 2 2 ot Figure Figure 3 is a sectional view on the line 3-n--3 oil Figure et.

Figure ais a sectional view on the line -ld ot Figure 3, the blower or ian `casing being shown in lfull.

llei'erring to the drawings, it will be seen that the cutter casing l is mounted adjacent This cutter casing is mounted in axial alignment with the blower or lian casing 5l and a single drive shailit 4l extends through the casings. ',lhis drive shalt carries the rotary cutter 5 and the lian cr blower. The statioinlry shear bar (S is hulicated :in Figure 2 and is carried by a shear bar support 7. The material is iled to the cutter by means o'i a pair ot rollers consisting oit an upper roller 8 and a lower :liuted roller S). Any suitable conveyor may be provided :for delivering the material to these 'feed rollers. For example, the endless chain'l() is indicated in Figure 2.

rlhe `lan casing or blower casing 3 is provided with a vertical discharge spout ll and with a circular inlet opening l). as may be seen particularly from Figure 2. This 'inlet opening 12 is relatively small and is located below the horizontal diameter ol the lian casing and. slightly past the vertical diameter through said casing.`

Also it is to be noted that this entrance opening is located intermediate the center oil' the casing" and its periphery.

It is to be noted that the outer frame or casing member 13 o l the main casing extends outside of the end oit the cylindrical cutter and is provided with a plurality ol' air inlet openings 'll as shown most clearly in Figures l and 3. These air inlet openings are located below the horizontal.diameter of the cutter.

A very short iieed spout l5 extends :from the member 13 to the flan casing and con verges to the cylindrical opening l2. This :leed spout slants downwardly and forwardly as maybe seen from the drawings. lt is provided with an opening 16 below the cutter, such opening being preferably substantially triangular adjacent its outer side and extending part way across beneath the cutter particularly beneath the shear bar support 7 as may be seen from Figures 2, 3 and 4t.

The luted roller V9 holds the material, while it is being fed, from lateral displacement and passes it across the shear bar to the rotary cutter.` The rotary cutter cuts the material into small lengths' and the cut material as it is drawn from the cutter, travels in its natural path from said cutter and is swept along by the inwardly passing streams of air. For example, it travels upon a lower layer of air which enters 'through the opening 1G and is further urged along by means of a stream of air which enters through the openings 14C. rl"he cut material therefore has au extremely short distance to travel and its natural direction of travel is utilized by causing the air streams to travel in the manner described above and indicated by the arrows in the drawings. The cut material therefore cannot under any possibility clog the feed spout but passes through this very short feed spout at a high ratey of speed directly into the blower' casing. Unnecessary and energy wasting air eddy currents are avoided by this construetion and the air is admitted and directedin a manner to conserve the power consumption and to insure against clogging. The small cross section of the feed spout and the very short distances'of travel of the cut material insures a very rapid travel of such material and prevents overloading of the fan blades, and as stated above, prevents clogging of the feed spout. Further it is to be noted that the cut material is delivered to the fan at a point between its center and periphery and relatively close to the delivery chute. The fan readily picks up the cut material carried by the air and forces it through the delivery chute. y It will be seen further that a novel form of ensilage machine has been provided by this invention which does not require an auxiliary food or auger between the cutter and the blower or fan and which has a direct connected cylindrical cutter and fan.

It will be seen further that the air currents so enter the novel form of feed spout that clogging of the spout or overloading of the fan is wholly avoided.

y' It will beseen also that the air currents are so guided or controlled due to the Iconstruction described in detail above that power consuming and wasteful eddy currents are wholly avoided.

Further, an excessive speed of the fan is not necessary with this device due to the cooperation between the cutter, the feed spout, and the fan.

Although the invention has been described in considerable detail, such description is intended as illustrative rather than limiting as the invention may be variously embodied and as the scope of such invention is to be determined as claimed.

We claim 1. An ensilage machine con'iprising a cylindrical cutter, a rotary fan having a casing provided with a delivery chute and having an entrance opening intermediate its periphery and center, a housing for said cutter, and a short feed spout leading from the under forward side of said cutter and converging lo said entrance opening, said machine having an entrance opening adjacent the end of the spout and below the cutter and extending across said cutter.

2. An ensilage machine conun'ising a cylindrical cutter, a rotary fan mounted upon said cutter shaft and having a casingl provided with a discharge chute and an entrance opening, and a short leed spout extending from the lower forward side of said cutter laterally downwardly and forwardly to said entrance opening, said spout lntving an air entrance opening below said cutter and extending across said cutter and paralleling the axis of said cutter, whereby the citt material travels generally in its natural direction as it leaves the cutter and is supported by a lower layer of rapidly travelling air while it passes to the entrance opening.

An ensilage machine comprising a cut.- ter, a housing` for said cutter, a. rotary fau, a casing for said fan having an entrance opening and a discharge chute, a short shallow closed feed trough leading trom the under forward side of said cutter to said entrance opening and having an air inlet opening bclow the cutter and extending laterally completely across the cutter and aplnoxiinately paralleling the axis of said cutter.

l. An cnsilage machine comprising` a cylindrical cutter and a direct connected rotary fan, a housing for said cutter, a casing tor said 'fan having an entrance ol'iening located in its side towards the cutter and to vards` the front lower portion of said casing and intermediate its center and periphery, a, l'eed spout extending from below the cutter lorwardly and downwardly and converging to said entrance opening, said machine having an air entrance opening adjacent the outer end of said spout and having an air entrance opening below said cutter and extending across the cutter, whereby the cut material is floated by an air stream entering through said last mentioned opening and is driven through said spout by an air stream l'rom the end opening.

In testimony that We claim the. foregoing we have hereunto set our hands at Appleton, in the 'county of Outagamie and Statie ot Yisconsin.
