WILLIAM KLOSTERMANN, OF YOUNG AMERICA, MINNESOTA.
MIDDLINGS-PURIFIER.
SPECIFICATION forming part of Letters Iatent No. 405,486, dated June 18, 1889.
Application filed June 26, 1888. Serial No. 278,299- (No model.)
To all whom, it may concern.-
Be it known that LWILLIAM KLOSTERMANN, of Young America, in the county of Carver and State of Minnesota, have invented a new and Improved Middlin gs-Purifier, of which the following is a full, clear, and exact description.
The invention relates to middlingsp u rifiers such as shown and described in Letters Patent No. 267,226, November '7, 1882, and Nos. 332,615 and 332,616, granted to me December 15, 1885.
The object of the present invention is to provide a new and improved middlings-purifier which is simple in construction and very effectively cleans the middlings of worthless stuff.
The invention consists of certain parts and details and combinations of the same, as will be fully described herein after, and then poi nted out in the claims.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figure 1 is a side elevation of theimprove' ment. Fig. 2 is a front end view of the same with parts broken out. Fig. 3 is a rear end elevation of the same. Fig. L is an enlarged transverse section of the drum. Fig. 5 is an enlarged sectional side elevation o f the same on the line 00 0c of Fig. l, parts being broken out. Fig. 6 is an enlarged plan view of aperforated sliding plate. Fig. 7 is an enlarged sectional end elevation of the discharge-spo ut. Fig. 8 is an end elevation of a device for imparting motion to the perforated sliding plate. Fig. 9 is an enlarged plan View of the shaker mechanism, and Fig. 10 is a sectional side elevation of the same on the line y y of Fig. 9.
On the rear end of a suitably-consti-ucted frame A is mounted to rotate in suitable bearings the main driving-shaft B, carrying on one end a pulley B connected by a belt with a pulley O, secured 011 one end of the shaft O, mounted to rotate in suitable bearings on the front end of the frame A. On the shaft O are secured the beveled pinions (3 meshing into the bevel gear-wheels D,fastened on the ends of the shafts D, mounted to rotate in suitable bearings on the main frame A and is prevented from moving endwise by a V- shaped annular rim F, formed in the middle of the pulleys F and engaging a correspondingly-shaped groove G in the periphery of the drum G. When the main driving-shaft Bis rotated, a rotary motion is transmitted to the shaft O, which imparts a rotary motion to the shafts D, so that the latter, by the pulleys E, impart a rotary motion to the drum G.
On the inside of the drum G are secured the longitudinal strips G extending at an angle, as is plainly shown in Fig. 4, and serving to carry up the middlings in order to drop the same on the middlings distributing box H, located within the drum G, which is open at both ends. The middlings-distributing box I1 is provided with the heads H and H fitting into the open ends of the drum G. To the heads H and H is secured a longitudinally-extending peaked section I, provided on each side of the top with inclined strips or rifflesl, extending at an angle of about fortyfive degrees, as is plainly shown in Fig. 5. On top of the peaked section I is held a longitudinally-extending gate J, which can be thrown to either side, so as to distribute the iniddlings on either side of the peaked section I. A longitudinallyextending stop-board H is secured to the heads H and H of the middlings-distributing box, which serves to stop the downward motion of the middlings remaining on the longitudinal strips G of the drum G. The inlet-spout H is held to the front end of the machine and discharges directly onto the longitudinal strips G of the drum G. (See Figs. 4 and 5.)
The lower ends of the peaked section I discharge into a riddling or shaking box K, supported inside of the drum G, directly under the distributing box II, by means of springbands K, each secured by one end to the frame A and by the other end to the outer ends of the said box K. The sides K of the box K are provided at their upper edges with the longitudinally-extending downwardly-inclined boards K on which the material is discharged from the lower ends of the peaked section I. The inner lower end of each board K discharges on a longitudinally-extending board K located directly below the inn er longitudinal edge of said board K and in turn discharging onto a longitudinally-extending rib K which in turn discharges onto an inclined board K located under the first-named board K Any number of such alternating boards K and ribs K may be arranged Within the middlings-box K, so that the middlings fall from one to the other until they reach the lowermost strip K. The strips are secured to perforated side plates K extending throughout the length of the box K, said plates K being provided with slots K", which are smaller at the top than at the bottom, increasing proportionately from top to bottom. The lowermost strips K discharge on the inclined bottom K extending longitudinally in the box K, and from the said bottom K the middlings fall on the longitudinal strips G of the drum G, and the light material passes into the center of the box K and upward between two longitudinal walls 1 secured to the under side of the peaked section I and to the heads H and H of the distributing-box H.
Between the two parallel walls Pis'held to slide a V-shaped plate N, provided with perforations increasing in size from the front end of the machine to the rear end, as is plainly shown in Fig. 6, to compensate for the varying strength of the air-blast as the discharge end of the machine is approached. The plate N serves to distribute the blast, and acts as a screen to prevent anything other than the lighter particles from passing out with the blast. The plate N is mounted to reciprocate longitudinally, and for this purpose is provided at one end with a rope N, extending to the outside of the head H and passing over a pulley N secured on the said head H and extending downward, being connected at its lower end to a lever N fulcrumed on the spout O of the exhaust-fan P, located at the rear end of the machine. The lever N is engaged by a pin N secured on the front of a worm-wheel N mounted to rotate in suitable bearings on the said spout O. The worm- Wheel N meshes into a worm C secured to the shaft 0, so that when the latter is rotated the worm imparts a rotary motion to the worm-Wheel N and at every revolution of the said wheel N its pin N engages the lever N which is pressed downward and pulls on the rope N, so as to move the sliding plate N toward the front.
" On the rear end of the sliding plate N is whenever the pin N has disengaged the lever N The sliding plate N thus abuts suddenly again st the head H, so that the middlings remaining on top of the plate N are distributed and acted on by the air from the exhaustspout O, which latter opens into the space formed below the peaked section I and between the parallel walls I on top of the plate N, as shown in. Fig. 4:.
The riddling-box K receives a forward and backward motion from the main driving-shaft B, which for this purpose is provided in its middle with an eccentric B on which is fitted a rod L, connected with the shaft L, mounted with its ends in a rubber bearing L held between two blocks L secured on the rear end of the box K and pressed toward each other by a screw L screwing in a threaded piece L fastened to the rear end of the box K. (See Figs. 9 and 10.) At the rear end of the box K is formed a chamber K which is open at the top, so that the last riffles I discharge into the open top end of the said chamber K, which leads into the discharge-spout K extending to the outside.
The exhaust-fan P is of any approved c011- struction, and is mounted on a shaft P, carrying at one end a pulley P connected by a crossed belt P with a pulley B secured on the main driving-shaft B.
The operation is as follows: WVhen the main drivin g-shaft Bis rotated in any suitable mannor, the drum G is set in motion, and at the same time the fan P draws by its exhaustspout 0 from the middlings-distributing box H, as above described. The sliding plate N receives a forward and backwardmotion in its hearings on the parallel walls 1 as before mentioned. WVhen the middlings are passed in through the inlet-spout H they fall into the strips G of the drum G, are carried upward by the same, and are distributed on the top of the peaked section I, from which they pass downward between the riflles 1 onto the inclined boards K of the riddling-box K. The latter by its forward and backward motion causes the middlings to pass down alternately onto the boards K and the ribs K, from which the heavier particles fall onto the bottom K and 'onto the strips G and the worthless stuff is sucked into the middle of the box K by the action of the exhaust-fan P, and is drawn up in the direction of the arrows, (see Fig. 4,) passing through the perforations in the sliding plate N, and from the latter through the exhaust spout O. The heavier particles are again lifted upward and discharged onto the peaked section somewhat farther in rear, as the riflies I, on account of their inclination, have the tendency to deliver the middlings toward the rear end of the machine. 7
The above-described operation is repeated, so that the middlings are constantly passed over the peaked section I, between the riffies I, over the boards K and K and the ribs K of the box K, to be separated from the worthless stuff, which is drawn upward through the plates N and into the exhaust-spout 0. When IIO the middlings reach the last riffle I, on the rear of the machine, they are thoroughly purified and pass from the said last riffles 1 into the chamber K from which they pass through the spout K to the outside. Thus it will be seen that the middlings are agitated over and over again, in order to thoroughly purify them, always separating the worthless stuff from the middlings.
Having thus described my invention, what I claim as new, and desire to secure by Let ters Patent, is
1. In a Iniddlings-purifier, the combination, with a rotary drum provided with elevatorstrips on its inner surface, of a peaked section held stationary in the said drum, inclined riffles secured to the sides of the said peaked section, a riddling-box held to slide longitudinally below the said peaked section, which discharges into the riddling-box, a feed-spout discharging into one end of the said drum, and an outlet-chamber at the other end of the said riddlingbox and into which the last inclined riffles discharge, substantially as shown and described.
2. The combination, with the rotary drum having longitudinally-extending elevatorstrips and a feed-spout which discharges into one end of the drum, of the relatively station-- aryinverted-V-shapeddistributing-boxwithin the drum, longitudinally-extending depending walls 1 having ways on their inner sides within the distributing-box, a reciprocating apertured plate N, mounted on said ways, an exhaust-fan opening into the said box at one end above the screen, and a reciprocating riddling-box under the distributer-box having apertured side plates K provided at their upper ends with inclined boards K extending under the lower longitudinal edges of the distributing-box, a vertical series of inclinedribs K on the inner faces of said side plates, and a vertical series of oppositelyinclined boards K under each wall I and discharging upon the ribs K a central passage being formed between the said two series of boards opening into the space between Walls 1 below the reciprocating plate, and the bottom K inclined oppositely from the center of the space between the boards K substantially as set forth.
