SMUT-MACHINE.

SPECIFICATION forming part of Letters Patent No. 600,319, dated March 8, 1898. Application filed August l, 1896. Renewed August 17, 1897. Serial No. 648,587. (No model.)

To @ZZ whom it may concern,.-

Beit known that I, FAUSTIN PRINZ, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Smut-Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to smut-machines, and is an improvement on the smut-machine for which I obtained Letters Patent lof the United States April 3, 1888, No. 380,348.

It has for its object to improve the construction of the cleaning case or cylinder whereby it may be easily put together and taken apart and be comparatively inexpensive to construct, while at the same time it will be durable and efcient.

It has further for its object to provide simple and efficient means for securing together the adjacent ends of the meeting edges of the metallic plates or bands which constitute the cleaning case or cylinder.

It has further for its object to improve the construction of the beaters by which the descent of the grain between the beaters and side of the cleaning case or cylinder is retarded, so that a better cleaning of the grain is obtained and breaking of the grain prevented.

To the accomplishment of the foregoing and such other objects as may be hereinafter made to appear the invention consists in the construction and in the combination of parts hereinafter particularly described, and then sought to be specifically defined by the claims, reference being had to the accompanying drawings, forming a part thereof, and in which- Figure 1 is a side elevation of the smut-machine embodying my invention, parts being in section and parts being broken away. Fig. 2 is an enlarged detail showing in vertical section a portion of one of the beaters, a portion of the cleaning-case, and a portion of one of the rings or pans which feeds the grain from beneath one beater to the receiving-plate of the beater next below; Fig. 3, a side view of several of the metallic plates used in building the cleaning case or cylinder and showing the straps and couplings joining the ends together. Fig. f1 is a plan view of a portion of one set of the beaters; Fig. 5, a side view of a portion of one of the upright bars placed at intervals around the cleaning case or cylinder and to which the pans are secured. Fig. 6 is a vertical section through a portion of one of these upright bars. Fig. 7 is a plan view of one of the segments of one set of beaters. Fig. Sis a side View of the same; Fig. 9, a perspective of two of the plates used in building up the cleaning case or cylinder, and Fig. 10 a cross-section through the same.

In the drawings the numeral 1 designates the upright legs or supports of the machine, of any number desired, which support at the top a ring 2, upon which rests the flange 3 of the top 4. of the cleaning case or cylinder. Between the legs 1 at the bottom is a bridgetree 5, which supports the lower end of the rotatable shaft 6, which :may be driven by the bevel-gears 7 and 8 or otherwise. The shaft 9 of the bevel-gear 8 may also carry the fanblades 10, which are employed for creating air-suction through the flue 11, the drum 12, and the flue 13, so as to carry o the chaff and other light material from the grain, which will be discharged from the bottom of the cleaning case or cylinder through a spout 14 into the spout 15,beneath which may be a trough 16 for directing the cleaned grain to the point desired. The numeral 17 designates a shell or drum which may surround the cleaning case or cylinder. The bottom pan of the cleaning case or cylinder is designated by the numeral 18 and. may be supported by brackets 19, securedto the legs or supports of the machine, and from this bottom plate the material is swept by the bottom set of beaters through a suitable opening into the spout 14. These parts so far described may be of any approved pattern and need not be more particularly described, as they do not constitute my present invention.

The numerals 2O designate a series of upright bars, to the inside faces of which are secured at suitable intervals apart a number of studs or abutments 21, which preferably IOO are made separate from the bars and formed with tenons 22., fitting in openings made in the bars and secured in place by riveting to j a number of metallic plates 25, each plate be-" ing formed on its inside face with transversely-extending cavities 26, which will afford good rubbing-surfaces for the grain, and in the bottom of which cavities are formed slots or slits 27, which will permit the passage of air and of finer particles of dust. These plates are adapted to slide into place between each upper and lower set of studs 2l, the faces of these studs preferably being beveled, as shown at 28, and the edges of the plates bearing against the studs correspondingly beveled, the edges of the plates lying directly back of the pans 24, as indicated clearly in Fig. 2 of the drawings. In this manner ways are formed for the plates, so that they can be pushed or slid into place, the side edge of one plate bearing against the edge of the plate next to it, and so on until the circumference straps assuming a circular form as they traverse the circumference of the cleaning-case. The two outside plates are then drawn together by means of couplings, so as to securely bind the band or belt in place. These couplings are formed of slotted angle-plates 32, the lips 33 of which extend at right angles to the slotted portions and are formed with openings for the passage of a threaded bolt 34, one of the openings being screw-threaded, so that by turning the bolts the two lips will be drawn toward each other and the end plates of the series thus drawn together and held by the screw-bolts. These couplings are applied after the plates have been put into position. The slotted portions of the angle-plates receive the nuts 31, as illustrated in Fig. 3 of the drawings, and these nuts form bearings for the angle-plates to pull on, so that the plates may be drawn together. It will be observed that one of the slotted angle-plates is longer than the other. The purpose of this is to admit of a more extended adjustment by leaving a greater space between the lips of the two angle-plates. It also permits the angle-plates to be adjusted in position without extending across the joint between the meeting side edges of the two end plates, whereby the joint between the plates will conform to the arc of a circle. It is obvious, however, that both angle-plates might be of the same length, provided that the nuts 31 to one of the end plates were set farther back from the edge of the plate. After one set of the plates has been put into position another set is placed in position above the first and between the studs which project from the faces of the uprightV bars, and so on until the cleaning case or cylinder is completed by building up these sections of plates in the manner specified. vThis construction admits of any one set of the plates being removed and replaced by another without disturbing the other plates. It also affords a simple and efcient construction and enables the case or cylinder to be built up to the height desired and the parts to be easily assembled in putting the parts of the machine together.

The rotatable shaft 6 carries a series of arms or spiders 35, the hubs of which maybe secured by set-screws or other means to the shaft, so that the spiders will rotate with the shaft. To the outer ends of the spiders are secured the plates 36, which lie directly below the opening in the return-pans 24, so as to receive the grain from the return-pans. rIo the outer ,edge of the plates 36 are secured the beaters 37. These beaters, plates, and return-pans operate substantially as in my patent hereinbefore referred to. Under the construction specified in that patent it was found that the grain would fall in a comparatively thin stream from the pans to the plates and in the space between the beaters and the wall of the cleaning case or cylinder and that some of the grain would become broken by the force of the blows and the rubbing action between the beaters and the wall of the case or cylinder. For the purpose of obviating that evil I provide the beaters, preferably at their lower ends, with laterally-extending lips or shelves 38, each lip or shelf partially filling the space between the adjacent beaters, and while permitting the material to drop between the beaters yet at the same time retarding its flow. These lips or shelves check the falling of the grain, so that it falls slower than under other constructions, and also causes the grain to accumulate to a greater extent in the spaces between the beaters and the wall of the cleaning case or cylinder and as the result breaking of the grain is prevented and a better scouring action obtained. Each plate 36 is preferably made in sections or segments, as illustrated in Fig. 7 of the drawings, and a number of these sections or segments bolted to the arms or spiders, so as to form the annular plate. The beaters and their lips or shelves are preferably cast integral withthe loo IIO

sections or segments, and the beaters may be j The grain is fed to the machine through the spout 40, which will deliver the grain to the top plate 41, which will be secured to the rotatable shaft 6, so as to rotate therewith. The grain is thrown from this top plate 4l centrifugally and into the space between the top beaters 37 and the wall of the case carried around and rubbed between them and the wall of the cylinder or case. It then passes down onto the pan 24, through which it passes onto the plate 36 next below, from which it is thrown centrifugally between the beaters and the wall of the case or cylinder, and so on down the entire series of pans and beaters until it is iinally discharged through the spout li at the bottom of the case or cylinder.

I have described with particularity the preferred details of construction of each part constituting the present invention; but it is obvious that changes can be made in the details Without departing from the essential features of the invention.

A drum or guard 42 is placed to the rear of the beaters and return-pans, so as to prevent the grain from rebounding into the space around the rotating shaft. This drum is stationary and supported from the return plates or pans.

Having described my invention and set forth its merits, what I claim is- 1. In a smut-machine, a cleaning case or cylinder formed of sets of plates arranged one set above the other, and each set formed of a series of plates placed end to end and connected together by straps to form a belt or band adapted to be bent into a curved form to form the wall of the case or cylinder, and a series of rotatable beaters within the case or cylinder, said beaters being provided with laterally-extendin g lips, substantially as and for the purposes described.

2. In a smut-machine, the combination of rotatable beaters, annular pans above the beaters, a case or cylinder surrounding the pans and beaters and formed of a series of plates placed end to end and arranged one above the other and bearing against the outside of the pans, and a series of rotatable beaters within the case or cylinder, said beaters being provided with laterally-extendin g lips, substantially as and for the purposes described.

3. In a smut-machine, a cleaning case or cylinder formed of a series of plates placed 5 54 end to end and flexibly connected together to form a band or belt, and a coupling for joining the end plates of the band or belt, said coupling comprising slotted angle-plates and means for drawing the angle-plates toward each other, the slotted portions of the couplings being adapted to receive abutments for the couplings to draw against, substantially as and for the purposes described.

4. In a smut-machine, a cleaning case or cylinder formed of a series of plates placed end to end, iieXible straps connecting the plates together and secured thereto by bolts and nuts, and a coupling comprising slotted angle-plates and means for drawing the angleplates toward each other, the slotted portions of the couplings receiving the nuts of adjacent end plates of the series to hold the ends together, substantially as and for the purposes described.

5. In a smut-machine, the combination with a cleaning case or cylinder, of vertical rotatable beaters located within the case or cylinder, said beaters being provided with laterally-extending lips to partially occupy the spaces between the beaters, substantially as and for the purposes described.

6. In a smut-machine, the combination with a cleaning case or cylinder, of rotatable beaters located within the case or cylinder, said beaters consisting of upright wings having braces extending from one face thereof and lips extending laterally from the wings to partially occupy the spaces between the wings, substantially as and for the purposes described.

7. In a smut-machine, the combination of a cleaning case or cylinder, rotatable plates within the case or cylinder, pans for directing the grain onto said plates, beaters located between said plates and the wall of the case or cylinder, and lips projecting laterally from 4said beaters to partially occupy the spaces between said beaters, substantially as and for the purposes described.

In testimony whereof I affix my signature in presence of two witnesses.
