IMPROVEMENT Iii-,suitrit-Nutte -Be it .known thatI, Da N P EASE, of the town of Floyd, in the county of Oneida, Vand State of New York,

'have invented a. new and useful Improvement in the smut-Milli and I do hereby declare that the following is a full, clear, and exact description of the construction and operation-of the s'a-me, reference Abeing had to the annexed drawings, Vmaking a part of this-speciiication, in which- Figure 1 is anexternal perspective view of the entire machine, including the improvement.

Figure@ ,is a perspective view ofthe lower part of the mill, partly turned round', showing the improvement at a, as it is connected ivith the mill, in the rear. Y

Figure 3 is a view of the part composing the improvement taken ed', and-shown separately.

Figure 4 is a vertical cross-section, `in outline, of the whole mill, including the improvement, and

Figure 5 is the essential part of the improvement, shown by a top view, and exhibits its connection with the, circular figure of the cylinder case, which contains the revolving part of the mill.

The object of the Aimprovement: is to furnish the means of spreading the grain as it passes from the mill,

iii order to a'ord greater facility for the air which passes up through it to separate and 'carry oif the foul stuff.. i It is designed to be used in connection with" my smut-mill, patented by me on the 22dday of September, 1868,

but may be attached to and used in connection with any other smut-mill or machine.

The-force of thei revolving cylinder, in the smut-mill, drawing in a volume of air, blows out, in a lateral direction,`most of the dust, chaff, and light stuff, and discharges it at A, fig. 1, and the` grain being brushed and scoured by the action of the cylinder, passes rapidly towards the discharge below, but still carries with it 'more or less light grain, chess, and other `foulstuti'l This is acted upon with a view to its separation from the grain by the swift current of air which it meets near the discharge at the mouth 'of.the air conductor f. But

in order that the sir should act advantageously for this purpose ,the volume of grain thus' descending Ato the discharge should be well spread and divided in the passage.l v This, as smut-millshave been heretofore constructed, is not sufiiciently provided for; and my invention provides a simple and e'ective spreader for this purpose, scattemgand dividing this volume of grain in such a manner as to permitthe swift current of air that passes up through it to carry oil' all the remaining dust, light grain, chess, and other impurities, leaving the grain better cleansed than has heretofore been done.` 'l

In the operation of the smut-mill the uncleaned grain is introduced to the top of the cylinder through a spout, not shown in the drawings, but is situated near the shaftof .the pulley b, fig. 1. It is cleansed by the action of a revolving metal cylinder, the stationary base of which is seen at c, fig. 2. When sufficiently scoured, itpasses off from the cylinder chamber through a. passage indicated by Ythe arrows die, iig. 4, and

entering the air conductorf, near its `Jmouth, is discharged at gf On entering the conductor f it meetsa stili current of air passing up the conductor', and which is drawn in by the swift operation of the fan-blower, located on the cylinder-shaft underneath the machine [I he circular easement of this fanfblouer is partially seen at k,

figs. 1 and 2. -This current of air carries the light impurities up the conductor-f, and over into the upright part l, according to the course indicated by the arrows n op, fig. 4. My improvement for spreading the grain is located in thepassage for the grain leading from the bottom 'or lovver part of the cylinder-chamber to the conductorf, and, forms the commencement or upper part of this passage. The passage within the spreader extends from k to l, iig. 2, and is of a length corresponding to the width of the flat conductor j', iig. 1. This passage is contracted in breadth as it proceeds 4to the end l, so that the last-of the partitions m, figs. 2 and' 3, almost closes across The shape of the wholepassage is seen at k, fig. 2nhere 2' is the bottom, and is on a level with the base of the' cylinder C. 3 is the farther side, and 4 a projecting portion of the opposite side.v

The parts composing the improvement are more distinctly shown in iig. 3, which is the attachment seenat k l,

iig. 2, taken oil' and shown separately.Y This new attachment I call a'spreader. The scoured grain in passing from thecylinder-chamber to the spreader, being driven with great force byl the swift action of' the cylinder,

strikes the partitions m, figs. 2 and 3. These partitions are placed vertically against the farther side of the passage, and extend forward over thefdrip4 or inclined base below, but'do notreach quite down toit; nor do they extend forward fully across the passage, but stop a little short of it, and nearl the edge of the bottom 2, iig. 2, and leave the front portion ofthe passage unobstructed. A portion of the passing grain strikes each of these partitions, and as it stiikes immediately falls to the drip below, which -leuds irito th'e conductorf, fig. 1. This operation divides'the'volurne of grain, and occasions it to fall in a vdivided sheet to thel mo nth of the con- Meer "ddctorf, whereit meets the swift current of air, ivhich carries up the lconductor the light grain, chess,- and other impurities, while the cleansed grain is discharged at the mouth g ofthe conductor. yIn fig. 1, the spreader is seen projc'ctingat GH,Where it is covered by its easement. G corresponds. to the cover G in gs..2und 3,

and H is the cover of the portion ofthe spreader on the opposite side of regulating slide I. This-reglilatin'g slide is an important agent. It is operatedbymans of the hnnd-`le`ver J.- It is hungon the fnlcrumpin-w, and

shuts de'n betweenthe covers G and H. l"If the grainfalls too much between the partitions 'nearestto k,.`

fig. 3, theslide I is let down to cut it oil" and send it farther towards the end Z of the spreader. If toolittle is dropped at the end k, the slide is raised. f This slide, Ain figs. 2 and 3, ieshbwnJ raised out'V of the way to show the partitions m and the spacesbetvreen them." In a mil-i of full size, these partitions arenbout tivo'and n. half inches apart. The passage forth'e grain from the spreader to the conducter f is angular in its course, as indicated by the arrows d c, iig. 4, .which also .assists inv spreading the voluuie'of grain as-it passes down. Figi' presents a top view of the spreader, as connected` with the circle-kof the cylinder case, .and with the'covers-G und H, tig. 3, taken o', so .este show theTup-per edges of the parts. Irithis figure, N is the upperedge of a y, l

narrow i'leifriblehoard or-plate, lying diagonally from end Ato' end ofthe passage,y as shdwn in theV figure, and is Vacted upon" by the, thumb-screw R."V It is braced atwnch end, but being vflexible. is capable of beingv pressed inward in its centre by the seremtojnarrow the; passage, and -to 4regulate the passage ofthe grain, and promote, nu: equal spreading of its volume. As Athe' impurities thus carried Aup the lair."conductor f, according tothe course of 'the arrows n 011 fig. v4, include lightgrain, chess, and other lighter material, theniill'is designed tb divide theseI materialmand separating' theglighter'and entirely valueless materials from the heavier portion, the formerfis carried over into the verticnlfportion z', fig. 1, of the conductor, andxis discharged at the month ofthe' fan-case at t, iig. 2, while the latter, 'containing material 4of some value, falls upon the inclined base 'u of tlie conv ductor, fig. 4, and sliding down this deelivity; isdischarged at the spout V, tigrl. For the puinose of impro-ving' this separation, I have madea longitudinal eper'xinglin thenvnder side, near the lower end of this declivitj'l-and fixed therein a fine screen of'wire cloth,',nt .'w,`lg 4,'for a'lmitting a current'of. air immediately under and quite across this broad conductor. Underneath this/inclined plane,and at the angle formed by it and the upright part 'of the conductor, is an enclosure,l te, figs'. 1 and 4.'. This' enclosure is divided into two apartments by the partition i y, iig. 4. In the upper part f this enclosure,and opposite the aforesaid wire screen, is an opening, Z, for the admission of a current of air to pass up through this wire screen, and thence through the aforesaid sheetoi' coarse= material as it descends, assisting `to carryover such dust and light stuff asmay still'be mingled therewithfinto the conductor z. .To this 'opening Z is aixed the slide vgate L, to .regulatethe vamount of air to be admitted. Ihus the dusty and light material are carried1 over into theeonductoi' z', and the heavier portion is dischai-ged'at the spout V, fig. 1, as before mentioned.v In the lower part of the enclosure x is another opening, to `which is aliixed a vibrating gute, vS, whiehis actuated by the entering current of air, which tends to closeit. It is opened 4against the force of this current bythe accumulating weigh'tof the descending material, which'passes thence into the spout V, and is discharged. T, fig. 1,'is another wire screen, inserted in the back sideof-thwspreider. This screen is also seen' at T, tige.l 2 and'3. It is intended as a vent for theescape of-the air driv'e/n 4til1rdi`igl1 thespreuder with the passing grain, to prevent this current ofar from affecting the strength of thecurrent drawn into the conductor-f by the action of the .an-blower. i D, iig. -1, is a swinging-valve gate in the'outside of the conductor z'. ,The strong draught, occasionedby thefswiit action'of tle fan-blower,tends to open this valve; and the weight E, hnngnpon a lever outside of the valve, keepsit closed.with a. strength'correspnding te the'length ef leverage .used in hanging the'vreightf.` If'the current of air in the conductor f is too strong, and carries up the. grain, less leverage is given to the ,weight E, allow'ingthe gate D to open, letting in a counter-current of air to modify'thestrength ofthecurrent in the lconductor f. This; .device is not claimed as new. ,i I d. V n

Having thus described myv i'mprvement, 'with its adaptation and operation, 'what 1 claim asm'y invention, and desire to secure by Letters Patent, is f y The spreadershown separately-ing. 3, and as oonnectedwith the smut-mill shovivxi in.A figs. 1 and 2, and fully described'in the specification. the whole hei-ng constructed, adapted, andarranged substantially-in the manner herein set forth. l
