SCRAPER FOR BOTATINGBING GEUSHING-MAUJPIINES.
Specification of Letters Patent. Patented Dec, 11, 191'? Application. filed February 2, 1916. Serial lilo. 75,629.
My invention relates to improvements in scrapers for rotating ring crushing machines, and has for one object to provide means for scraping the material of]? the ring after it has passed between the ring and crushing roller. It has for another object to gradually feed the material through the ring step by step after each crushing stroke of the roll against the ring. it has for still another object to turn. over and stir up and otherwise agitate the material so as to prevent packing of the material on the ring. Uther objects will appear trom time to time in the specification. My invention is illus trated more or less diagrammatically in the accompanying drawings, wherein- Figure 1 is a transverse section through the roller machine perpendicular to the axis of the roll.
lFig. 2 is a section along the line 2-2 of llig. It.
Fig. 3 is a section along the line 3--3 of lll'ig. 1..
ltig. t is a detail section on an enlarged scale along the line M of Fig. 1.
Fig. is a side elevation detail showing one of the guide rollers and its spring mounting.
Like parts are indicated by like letters in all the figures.
it is a rigid foundation containing within its interior a hopper AU, from the bottom of which leads a discharge trough or channel A A A are pillow or hearing blocks anchored on the top of the base A and carrying the shaft A which shaft is adapted to be rotated by power applied to the pulley it. The shaft A carries between the hear ing blocks A, A a crushing roller A". A is a shield or housing substantially closing the upper portion of the hopper and raised above the roller.
B is a rigid ponderous crushing ring. It rests uponthe roller and hangs down into the hopper A B is an annular track on the ring 13. lit engages on either side the channeled rollers B which rollers are supported in bearings B tree to move for a short distance along axial lines, the springs B being provided to yieldingly hold in the center these rollers. B is an annular interlining for the innerperiphery of the ring. It is held in position on oneside by a collar B bolted to the discharge side of the ring and on the other side by a collar B, which collar is otlset to contain a wood filler B and extends inwardly toward the center of the ring to provide a material holding flange B It willbe observed that the inside diameter of the ring is larger than the outside diameter of the roller, so that as the ring hangs on the roller, there is a sharp appreciable gap between the ring and roller at all places, except along a supporting line of contact which line is parallel with the axis of rotation of the ring and roller, and which line is located immediately above the center of the roller. Rotation of the pulley and roller will, of course, cause the roller to drive the ring, the ring rotating at the same peripheral speed as the roller, and thus at a lower angle of velocity. B is a feed chute whereby material to be crushed may be discharged into the interior of the ring ata point adjacent the feed edge oi the ring. This material is discharged to the inner surface of the ring so as to fall upon the more or less soft and adhesive wood filler at a point above the bottom of the ring, so that the materialas it falls down along the surface of the ring under the influence of gravity will have given to it a degree of velocity in the same direction as the direction the ring is rotating, thus the material fed to the ring rapidly takes up the ring velocity.
(l is a scraper knits or blade extending across through the interior of the ring. It is mounted on the pivotal arms C Rods U extend outwardly from the arms through brackets C andare drawn yieldingly outward todraw the scraper against the ring surface by the springs C. This scraper, it will be noted, is self-sharpening, because pressed diagonally against the surface of the roller as the scraper is Worn away a fresh cutting surface is always presented to the surface oi? the ring.
D is a supporting beam extending across inside the ring beneath the roll and slightly below and to one side of the lower discharge edge of the scraper blade. Upon this beam l) are pivoted a series of deflecting plow-like guide members 'Each of these guide members is also pivoted on an adjusting bar 1) by means of a bolt D whichis adjustable in a slot D. The bar itself is bodily movable, and may bem'oved into and locked in adjusted position by means of the set screws D D in lugs D D engagingfa stop D. Lock nuts D are provided for locking the set screws in position. The movement of this rod changes the inclination of all the guide members together in unison, while an adjustment of any one with respect to the rodmay be provided to change the inclination of any one. Preferably my. device: is set up with the inclination gradually decreasinglfrom the feed to the discharge side of the roller.
The use and operation of my invention are as follows-:-
fThe roller is driven by power applied through the pulley in the usual way. \Vhen it rotates it carries the ring with it. If there isno material beingerushed, the roll surface and ring surface will be in. contact. \Vith the roll and pulley in rotation the operator commencesto feed'ofi material through the chute as indicated. This material falls upon the'filler strip at the edge of the ring and tends to slide downward toward the lowest part of the ring. This filler strip is of wood and tends to take hold of the material and give it further velocity beyond that caused by a free fall under the influence of gravity. This velocity is suflicient to cause the material to, adhere to the ring and be carried over withit as it rotates. The material thus carried aroundthe ringrides over the roll andis crushed between the ring and'roll by the weight of the ring on the roll. This weight is very large and amply sufficient to partially crush the material. The, material by this crushing blow or troke will be more or. less compacted on the surface of the ring. .The ring goes on around carr yingthis compacted material with it until it reaches the scraper. The scraper with, its sharp edge lifts or peels or scrapes this material off the ring, and the scraped material'drops down along the back of the scraper and is discharged onto the upper edges of the deflectors or plows. These deflectors or plows turn the material over and discharge it to one side of its original path. It drops from them downv along the surface of the ring in the same general direction without any very great loss in velocity. Itis then carried aroundthe ring: again, and this process is repeated. In other words, each particle of material which is fed into the ring on the feed sideis carried around andaroundthe ringv being crushed each: time until after it has made as many; short; steps longitudinally there are deflectors, itis discharged from the discharge end of the ring. Depending on whether the operator wishes to feed the material through the ring rapidly or slowly, he
changes the angularity of the deflectors or plows. If the material is hard to crush and he wants it to go through slowly, he will give them a very slight inclination. If he wants it to go through fast, the inclination would be increased, and the step made by the material in each crushing will be increased. If the material starts in coarse it comes out fine, so that in order to keep the ring and roll parallel, and to keep a proper pressure on thematerial at all points it is necessary to increase the amountof material toward the discharge end. This effect is obtained by changing the inclination of the plows adjacent the discharge end. Preferably the inclination of the plows will progressively decrease from the feed to the discharge, so that thematerial will decrease in speed through the machii'ie, th'us banking up to provide the needed increased amount of ma terial. to give the desired even thickness of blanket over the surface of the ring.
