To allwitom it may'comem:

Be it known that l, JEDGAJR IBlfixnroivs-a citizen of the United States, residing at. Gin

cag'oyin the I-coulnty of-Co'okand State of 'fllll'mois, have invented a. certain new" and- "useful Improvement in 'Fotating-Ring rushing-Machines, of which the following -r is a specification.

My ventlon 'relates'primarily crush-' ingor fine reduction machines wherein the materialis to be pulverized or very finely reduced. In order to produce this result,

- 1 and in order to do it rapidly, it is necessary 'jjthatthe material 'be spread or arrangedon'j 'the crushing surfaces in the form of a thinf layer or film prior to and during the process:

v of crushing, and this necessitates in the peculiar form of roller ring and crushing ma- E' jchine which llh'ave shown, a ring in which thedischarge side or sides are completely open and free to discharge the material at; all times absolutely without. hindrance. -'llhat is to say, the presence of a screen or a selective member of 'any' kind whatever would interfere with the operation of my de: vice by causing a banking up of the crushed material at the screen, and thus the film so necessary would no longer be had.

In my device, therefore, I have provided an arrangement wherein the diameter of the. .exit opening, that is to say," the diameter at the extreme ends of the crushing ring is ef- 5 fectively equalto the diameter of the ring at that point.

'][f this thin cause the crushing element itself cannot be relied upon satisfactorily to feed the material and this feed is necessary to prevent bankm gap and preserve the of uniform and predetermined thickness.

My invention therefore relates toimprove-L ments in rotating ringcrushing machines.

It is illustrated more or less, diagrammati-- cally in one form in the accompanying drawin s, wherem 1 lgure 1 is an end elevation in part s'ection with parts broken away;

This crossbar is provided with curved slots E so that it may be moved-longitudinally to adjust the inclination of the guide plates E which are each secured to the crossbar E by the nuts E engaging slots E in the crossbar itself so that each individual guide plate may be adjusted with respect to the remainder or with respect to the movable crossbar itself.

Either chain 13 or F may be dispensed with.- r

In the modification shown in Fig. 5, the ring is centrally hollowed at G to adapt the machine for crushing from relatively large ring may take any form or shape. I have suggested the structureshown in Fig. 5.

With such an apparatus it is necessary, and with any form of ring it might be desirable to spread the material from the center outwardly in either or both'directions. This is accomplished by a structure such as that shown wherein the spreading plate E", E are arranged on one side at one angle and on the, other. side at the opposite ang'le. To do this effectively, I provide separated bars G, G, each secured referably by means 0%. a slot and pin G to the side bars E and gether by a link G by means of the slots G Gr and set screws G, G whereby the two bars .G and G are adjustable to and from each other. as to be downwardly inclined toward the middle line of the ring. Each of the spreader plates is preferably secured to its proper cross bar Gr by means of the arc- .shaped slot and set screw G so that the individual spreaders may be separately adjusted. G" is 'a short link which connects the two bars G Gr to which the other ends hollowed out.

It goes u The two bars G, G are secured'to- They are mounted so.

of the Spreaders E are pivoted. By this means the spreaders may be adjusted in any desired manner to accommodate themselves to the service required in connection with a ring where the material is fed near the middle and to a ring whose surface is inwardly Gr is an inward extension of the feed-spout which delivers near the middle line of the ring and at one side of the spreader device.

- It will be evident that while I have shown in my drawings an operative device, still many changes might be made in size, shape and arrangement of parts without departing from the spirit of my invention. I wish, therefore, that my drawings be taken as in a sense diagrammatic, and I do not wish to be limited to the particular devices shown or to the particular elements of the machine accompanying the essential features of my invention.

The use and operation of my invention are as follows:

The crushing machine is started by rotating the shaft in the usual manner. This causes the ring to rotate, since the ring is supported on the roll. The material to be crushed is then fed in through the feed spout and discharged into the annular feed pocket at one side of the ring. When this pocket is filled, (-11 reached by the first guide plate, which, acte material piles up and is their ing as a plow or guide, feeds the material over into the crushing zone. The material, of course, as it falls into the feed pocket and is fed into the crushing zone is held by centrifugal force against the inner surface of .the ring, is carried around and when in the "feeding' zone, is acted upon'by the crushing roll, being crushed thereby, the weight of the ring crushing the material against the roll as an anvil. The material after being crushed comes around and strikes the next guide plate and is by it moved slightly over.

continues until the material has passed completely through the ring, making as many complete revolutions to make this passage as there are guide plates. The material is pushed off the ring at the bottom on the side opposite the side at which it enters, and is discharged by centrifugal force downwardly into the receiving hopper.

It will be understood hat as the coarse 'material is fed in, at one side of the ring,

- ward the discharge end.

It will be noted that I have made proviand is again crushed and comesdown an strikes the next guide plate. This lat sion for both means of adjustment. I have always at' substantially the same position shown the inside diameter of the ring but since they rotate about difi'erent axes slightly larger at the feed end than it is at and since their peripheries are substantially the discharge end so that as the material tan ential, it is obvious that they do efi'ecby being reduced packs down and occupies tive y at least have a movement and do in less space, it will still always be crushed by eflect have or form a crushing stroke since the ring. If this adjustment is notsuflicient, any point of the surfaces will gradually or and under some circumstances it might be successively approach it and recede from insulficient, it is only necessary to adjust the other surface. n

The result of this will, that is to say, while the crushing ring and 15 ofcourse, betohave the material bank up crushing roll are always in contact, still any to a certam extent so that more material will one point on the crushin ring is treated by he in the ring toward the discharge end a series of successive b ows, one blow octhan is in it adjacent the feed e'nd,,and-this curring each revolution ofthat point when will compensate for'thfi'ndflcreased bulk of it asses the roll.
