MITTS QUENNER, OF SANTA ANA, SONOR-A, MEXICO, ASSIGNOR, BY MESNE ASSIGN- MENTS, TO QUENNER DRY RATION OF ARIZONA,

CRUSHER COMPANY, OF DOUGLAS, ARIZONA, A CORPO- ORE-TREATIN G MACHINE,

To all whom it may concern:

' Be it known that I, Mrrrs QUENNER, a citizen of the United States, residing at Santa Ana, Sonora, Mexico, have invented certain new and useful Improvements in Ore-Treating Machines, of which the following is a specification, reference being bad therein to the accompanying drawing.

This invention relates to a machine for breaking up material such as rock, coal and othersubstanccs and has for its primary object the provision of instmmentalities for expeditiously and effectively accomplishing the result stated.

Hcreto-fore in the art of reduction, especially that branch of the art which deals with the reduction of masses of stone, coal or other lump substance-s, it has been usual to subject the material to the crushing action of rolls, jaws, stamps or hammers, all of which require the material to be backed up or supported so that the crushing force will be directed against the material and resisted in the main by the backing or supports. r

In the use of machines designed to assist in carrying into. practical effect the m above referred to, there has been the inherent production of a very considerable amount of' pulverulent or fine material which though desirable in some instances is absolutely useless in others. For example, in breaking coal, to reduce the size to the proportions required for use, and when breaking rock to reduce the size to the proper proportions, as

in the product known as road ballast itis very desirable to avoid, so far as possible,

any crushing action of the stone or coal and thus substantially eliminate the production of fines and culm. It is the foregoing condition of the reduction art that is met and improved upon by a new method of breaking or shattering the rock, coal, etc, devised by me and by my improved machine constituting the subject matter hereof, designed especially for use to facilitate the carrying of said method into practical efieet.

Generally speaking, as distinguished from a crusher or grinding machine, the principal characteristic of in present machine is its breaking or shattering operation.

I have illustrated in the accompanying drawings the preferred embodiment of my invention, although it will be noted by thoseskilled in the art that the invention is ca'pa- Specification of Letters Patent.

bio of embodiment in still other forms and arrangements.

Features of the above mentioned machine are the provision of breaking or shattering instrumentalities comprising a rotatable shaft. and a plurality of flexibly mounted projectiles arranged to strike and shatter the rock and conveniently disposed to cause the.

somewhat after the manner of an ordinary screw conveyor.

Still other features are means for closing the discharge end of the cylinder or grizzly effecting rotation of the projectiles and feed and discharge openings at the opposite ends of the grizzly tending to canse the Ina-- details in the construction and' arrangement of the parts of my machine will bsapparent 1 from the detailed description hereinafter contained, when read in connection with the accompanying drawings forming part here-. of and wherein a convenient embodiment of the discharge of material through said end, said regulating means being preferably adjustable; means for ad *justing the grizzly to regulate the size of the escape passages therethrwgh; means for spirally grizzly in the same direction but-at differing speeds; and a relative arrangement or the the invention is illustrated. Itis to be un- 4 derstood, however, that although I have, for the sake of imparting a full understanding of my invention, illustrated a special enibodirnent thereof, the invention is capable of embodiment in other forms and devices than that disclosed herein without departing from the spirit of-zny invention.

J represents grizzly provided at its op posite ends with mitwai'dly ii-ejecting suppoiting hinges it adapted to rest upon the peripheries .m. the flanged- Wheels ll, as clearly shown in Figs, 1 am! 2, it being here observed that the wheels H constitute the only moans of supporting the grizzly, the let! 1: being ielltl. in p .(re by its own weight. and the i ,-ght t inihirial l) treat ed therein, the rcspczrive pairs of x eels being separated to 3.50mi a. firm seating for the grizzly preventing any tendency of the same to become displaced. in a lateral clirection, and the flanges of the Wheels H engaging the outer of the flanges 71 of the grizzly preventing any entwise movement thereof. The grizzly is provided with ends or heads j (Fig. 4') having circumferentiizlly slotted interned flanges Ior aleteehahly seeming the slats K in place, the t slats being similarly slottetl,

so table bee rings in ii tiles h ihly connected thereto,

Wide relative to the other slats which are inter; icilizzie tliererdi. lhcse wide K are fixed to the heads and constitute with said heads What may he termed the frame of the gr zzly. In adjusting the grizzly, only those nflriow sluts between the broad slats K are shifted, thus facilitating the quick adjustmentof the parts from opposite sides of the grizzly, it being observed that when the slats are arranged in close proximity to each other with relatively fine passages therehetwecn, an :1 (lditional slat maybe inscrted between the end narrow slat and the adjacent Wide slut K", which said additional slat is removed when the narrow slats are pc itimieil at correspoiz lingly wider distances apart.

The frictional engagement between the grizzly and the flm'igcil wheels H is sui fieientto enable the grizzly to he rotntcil under the :ietuation of the driven wheels ll on one of the shafts as hereinzrlim'e set forth, the heads being open for quite {U1 c.\'- tent around the shaft 1) to permit the grizzly to rise and fall in keeping with the wheels H to constantly preserve it firm content ther'ehe Ween.

ilpon the shaft ll {Hill arranged Within the grizzly is a multitude of projectiles I.

l woymrt collars l. \(lHplQ-(l to embrace and lie lioimtl in position upon the shaft. D by binding bolts and nuts M secure the same in place. The two parts oi the collar are of such form that the QiHls thereof when drawn toward each other by the bolts and nuts M will not engage, but will leave a space N thcrelt eiween for the i ntrmluction of the enil link of a chain or flexible connection 0, Wherehy the b lt M may alsoconstitutc tho ii'mnwlinte fastening mean: or the flexible away. Normally the projectiles terminate at a point short of the inside of the grizzly so as not to engage and unduly cut or Wear the bars of which the grizzly is formed. In Fig. 6 it is clearly seen that two of the flexi- 'bly mounted projectiles are secured to each of the collars, and a highly important feature of the relative arrangements of the suc cessive pairs of projectiles is the fact that they occupy a progressively slightly advancin relation to each other so that the re su tant action of the rojectiles is substantially that of a spira, which in operation under the rotation of the shaft causes the projectiles to act somewhat after the manner of a feed screw to efi'ectthe travel of the material being treated from the feed end of the machine to the discharge end of the same. Of course the projectiles are thrown outwardly into their operating position and relation by centrifugal action 1ncident to the rotation of the shaft D as hereinbefore pointed out. \Vhile the projectiles are thus thrown out by centrifu a] force they are held to a normall circu ar path of movement by their fiexib e connection with the shaft D. It is to be observed, however, that the said connection represents largely a tether confining the projectiles to movements within certain limits. This is important in that when the projectiles strike the material no destructive vibrations are transmitted to the shaft. Again there is practically no impediment to the continued movement of the projectiles after the blow has been delivered, the movement of the shaft drawing the projectiles around the rock or portions which may be in the, path of the projectiles after impact. Should the impact be delivered or resisted at a. point between the projectile and the shaft, he result would be that the projectile ,would be drawn down by its momentive force onto a portion of the rock, the blow being in the direction toward approximately the center of the grizzly. This tethering of,

the projectiles enables the machine to be run at a veryhigh rate of speed so that effective blows can be delivered rapidly on the ol strut-ting material and thus quickly shatter and break up the him 5 or rock.

Q is a feed hopper leading to an opening q in the adjacent head of the grizzly, the hopper being mounted u on a bracket g to be held stationary at all times.

R is a flaring flange carried by the discharge head or end of the grizzly and secured thereto so that it rotates with the grizzly, this flange being arranged to serve at all times as an inclined conducting surface to guide the material discharged from the grizzly J to a stationary inclined grizzly S iseharging to any suitable auxiliary treating machinery .or to any point desired. The discharge opcning T of the grizzly is of sometate them, tie pulleys d what greater diameter than the inlet open ing r as is indicated in Fig. 4, so that the material being treated tends to traverse an incline approximately on the dotted line it from the inlet to the outlet, which will assist he heaters in effecting the desired feed of the material.

U is a door or closing plate for the discharge opening T, the same being sleeved upon, the projectile shaft 1) and held in fixed position and free from rotation with the grizzly by a bracket u projecting inwardly from the adjacent upright portion B of the frame. The lower ortion of the plate U is divided horizontally and hinged along the line of its division as at 'v, to constitute a hin d flu or door V, the same being normafi held in closed position through the medium of an adjustable spring retaining device W supported from a bracket 10 on said upri ht portion B. It will be obvious that by adjusting the nut of this spring device, the flap or door V will open .or close with greater or less pressure from the interior 0f the grizzly as the case may be.

X are deflecting plates arranged parallel to the axis of the grizzly and adapted to guide substances escaping from the upper portion of the grizzly down to the ground or into suitable receptacles at the base of 95 the same.

From the foregoing description, the operation of the machine may now be followed. The OpOIHtlII medium being applied to 1'0- and 9 will, through the medium of their respective belts, d, g rotate the pulleysd and 9, thus etlecting rotation of the projectile shaft I) and one of the shafts with the pair of flanged wheels H thereon. The grizzly bearing upon said wheels will be eorrespondingly rotated, tending to move, carry upwardly or turn over, at relatively slow speed, the material introduced through the hopper Q. The flexible projectiles on the shaft 1) will be rotated in the same direction but under a relatively high speed to combat the material in the grizzly and break the sanuup, as desired, the centrifugal action .xtc ding all the projectiles and the spiral arrangement of the projectiles imparting the desired feeding lllflvtil'llel ll to the shattered or broken material from 1116 end of the machine to the other. The machine will ac commodate material of any size which may be fed thereinto, and as the material is dolivcrcd to the machine, the grizzly having attained its relatively slow rotation and the projectiles their correspondingly high rate of movement in the same direction, the umterial is struck repeatedly and shattered by impact blows delivered in a direction slightly tangent to the walls of the grizzly.

The unshattered parts are subjected to repeated blows pro ecting the rock forward w against other moving hodies of rock and this continuous action of rapidly repeated impact projectile l)lt)\\', soon shatters the rock without eil'ecting any material or substantial erushiir; or pulvcrizing thereot'. As the rock particles hecomc shatt red or lu'olten to a size which will permit them to escape through the opening: hctwecn thc slats they are gathered helow the uachinc or may lro fed to any suitahle receptacle or separator. The adnmce or moving 4,! turning over of the material by the grizz.y or cage prevents the material from assuming a condition of rest and thus a backing which might other- Wise be present is substantially avoided, this insuring the material being treated in what may he termed a floating tree or moving condition. Any of the line or lighter particles ot' the material escaping from the up per portion of the grizzly or the sides thereof are deflected dovinwardly hy the deflecting side plates X. as hetore noted.

The size of the material regula ed by the adjustment of the escape passages he tween the slats of the gr1zzly and hy the speed of rotation of the projt tiles. Owing to this adjustable (ltzllt\tltllr-lit of the machine hoth respecting arrangcnu-nt of parts and relative speeds of nnncment. the 11111- chine is capahle of use in yarions in,-.tanccs other than that use for whith the in\t-ntion was primarily designed. to nil. as a hrcalting and shattering mechanism f r rock, etc. For example by firmly closing the door to practically prevent escape ol material. the machine may be used purely as a crusher or pulvcrizcr, reducing all of the material i11- troduced thereinto to a given degree of lincness determined by the escape passages through the slats ot the grizzly. Further. the machinery may he used as a mill or mixer hy n'actically closing the slatted periphery o the grizzly together. to form a substantially continuous solid wall when the material will he treated hv the projectiles and gradually ted in its entirety through the tlap or door V.

I mention the foregoing matters to illus tratc the various uses to which the machine may he put; the same having heendound ellicacious in all of the ptlllltlllill'h' noted.

I will not claim herein specifically the suhsidiary part or ldrcolultilittlion ot my inyention involving hroadly the rotatable grimly and the special means for closing the discharge opening thcrcot' inasmuch as the .s-unc more properly constitutes stlhject ma tcr tor a divisional application.
