Letters Patent No. 110,191, dated December 20, 1870` The Schedule referred to in thse Il'lettcrsal Patent and malldng part ot the lame.

To 'whom 'it mayconceru.-

, Be it-known that I, J. ADAM Benzine, Jr., of

Y Oswego, in the county' of Oswego and State of N ew York, have invented a new and useful Improvement one of the staves of the case removed to show the in'- terior arrangement thereof'.

Figure 2 is an elevation of `the upper fan-case from the discharge side. e,

Figure 3 is a vertical section of my machine.

Figure 4 is a perspective ot' the cylinder, beaters, and supplementary fan. p

Figure 5 is a perspective of the inner side oi' one of the casing-stares, showing the peculiar arrangement of the scouring service.

The nature of this invention relates to an improvement in the construction of machines for removing smut from wheat; and

1t consists in the peculiar arrangement orconformation of the corrugations on the inner wall's of the ease, known as the scouring service; in the employment of a supplementary fan in the lower part of the cylinder, so arranged as to throw stray kernels outward to the beaters; in the peculiar arrangement ot' thclbeaters with relation to the cylinder and scouring service; and in the arrangement of certain' conductors conveying from a channel in the upper periphery of the case into the fan-chamber, whereby the large percentage of smut eliminated from the graiuas it strikes the top plate of the cylinder is at once 'carried away, as more fully hereinafter set fort-h.

In the .drawing- A represents the rectangular frame of the machine, which is properly inclosed by tightly fitting panels B.

C is a. vertical shalt, steppedI and journaled in the center of the frame-work, extending up through the fan-case D at the top, and provided with a pulley, O', near its lower end, by means of which it is rotated at a high speed from any convenient source of power.

E is'the cylindrical scouring-case, constructed as usual in sections or staves of hard metal, but differing in the internal dress or scouring service, shown in iig. 5.0i the' accompanying drawing, in which it will be seen that the corrugations a do not extend continuously from end to end of thc stave, but are broken or interrupted at short intervals. The parallel rows of corrugations are not vertically disposed in the stares, but are slightly inclined or traverse the face diago nally.

b are the smut-openings, which, for thc reasons hereinaftergivemd am enabled to make much larger on the outside than usual, thereby facilitating the passage of the slnnt.

F is a disk, and

F are a pair of spiders secured to the sh'aft 0,'forming the'cylinder, to which the beaters G are diagonally secured in a contrary directionI to the disposition of the corrugations in the scouring service. These six beaters, half the usual number, are Atangent to the periphery of the cylinder so as to throw the grain to the case. l

His a small fan secured -to the shaft within the lower hal-f of the cylinder, and its blades are so arranger1 as to draw ina supply of air throughthe open ings in the bottom E' of the case, and direct al blast outwardly'aganst the scouring service, so that any.

stray grains falling \vithin the beaters may be thrown out to be caught by the beaters, and by them dashed against the corruga-t-ions.

The bottom of the case tlares from the apex of the opening to the path of the lower ends of the beaters,

so that the scoured grain may be carried by them to the spout I leading therefrom to thc blast-separator J, open at its lower end, extending up over the top ci' the machine and terminating in a drop, J', as is usual in all such machines.

' Within the fan-case D a fan, K, is mounted on the shaft G, its principal supply of air coming through the perfor-ations ofthe scouring-case from the inside, thence through the opening in thc bottom of the fan-case, as shown in iig. 3. It also receives alimited supply from that part ot' the blast-separator which lies just above it, as shown inthe same ligure.

The suction thus created in the separator is sufficient to carry up the light grains which enter it with the sound berries. atl, whilel the heavy onesfall of their own gravity.I The impurities. are blown lout at the side of the t'anfcasc in the usual manner, while the light grains are discharged at the drop J'.

Around the upper periphery of the securing-case extends a channel, c, from which several tubes, d, con verge and terminate in the lower opening in'the fancase.

L is the spout through which the grain is fed to the machine, impiuging as it enters, ou the disk l1 ofthe cylinder, which, in its rapid rotation, breaks up and sets free a. large percentage ofthe smut, which is carried around inthe channel c tothe tubes d, whence it is at once sucked np by the fan and discharged withont going down with the wheat through the mill, which it relieves to that extent, lessening the number of beaters, and consequently the amount ot' power required to operate the machine.

The grain now falls over the edge of the disk, when it is caught by the beaters and dashed against the curi ugatious, breaking up at the remaining sn'iut-l'ialls, and, fi'ointhe peculiar arrangement of the eorrugations, the wheat cannot fall directly down, but must be turned over -many times, thoroughly scouring it before reaching the bott-om, whence it is discharged asusual.

The dust ot' the smut is during thistime sucked ont through the perforations b by the action of the fan, carried up, and blown away.

As before mentioned, the openings b are widely on the outside oi' the stares, facilitating the passage of the smut-dust through them, preventing its a'eeulnulation in the case ort'obstruetiug the openings.

- Iam enabled to make these opening moreiiaring than usual, from the fact thatthe grain in passing through the case d oes not slide-in continuous contact with the groove-faces, but is kept constantly turning over by the scouring service; consequently the metal about the openings .is notworn away to enlarge them, a's is the case with other machines. A seruifyv outside portion of the bran, particularly at theblow end of the grain, has always hitherto been very diticuit to eliminate. It suiieient velocity were given the cylin- What I claim as myinveution, and desire to secure.

by Letters Patent, is i 1. The combination of the case E provided with the openings b, and eorrngations l with the fau H, shaft yO,.all constructed and' arranged substantially as described and shown for the purposes set forth.

2. The combination of the 'disk F, the spiders 1*", the bottom E', the beaters G, and the shaft C, all constructed and arranged substantially as described and sh0wn,'forvthe purposes set forth. y
