The Objects ofv thisinvention are: I V
to produce an improved and. cheap ap paratus for treating gralvel inorder to free-it from. rotten stone, hard clay lumps, agglomerates,
g, or. the like; which are present in gravel. even .aiter washing and which greatly interfere with they value of gravel for use as on eggresotein concrete work V II.
Second, to provide such an apparatus that will treat gravel which has been screened to size and .wilL-by the erushingsction of the bells}.v itate it withthe gravel; and remove the obiec-tienable. material referred to, l I
, Third, to providesuch an apparatus in which m; the gravel to be treated-is fed continuously at one end of the machine to. come outif-ree from. the objectionable materiel; I
1 Fourth. to. provide such an apparatus for carry ing out the method disclosed in-mycopendins anplicetion. for-Letters Patent filed, April r9, 1934. I

3 is: a conventionalplanview of ap- I stood that this. construction can be departed from paratus showing the driving means.
Referring to the drawing, l. isa. box preferably.
constructed of metal and adapted to receive gravcl from a hopper; the discharge of. which is shown angle pieces-4 positioned near the bottom'of the.
The box I is approximately twelvefeet long by sixfeet wide. and is mounted at anangle of about. 5F 20 degrees to the horizontal, sloping away from Serial NO. 7.2.1.268"
A, structure which is a. preferred embodiment 01* my invention. is illustrated in the a.ccompzmyilris'.v
therein. which will be later-described. I. prefer to s Claims- X01. zoo-e) I f the hopper discharge 2. I The box is. mounted for agitation by -eny suitable shaker mechanism. The shaker mechanism disclosed is illustratedin detail in 2. A pair of eccentric shorts. 8 ex.-
tend transversely of the. box. .The shafts have. 5,
eccentric portions 9 fitted inbearings l0 fixed to the side plates. 2' of the box I. The shafts are mounted in bearings H which are. mounted on any suitablesupportand are provided at theirouterends with sprockets l2. connected by a. silent chain 13 which synchronizes the ration, to insure roperoperetion of the. shaking mechanism. One shaft is-driven by any suitable means and; the other shaft is driven, through the sprocket l2 endchein In, H 15.
3. I show a. plan view-oi the app ratus showing. the box I, tnesyncbronous chain H. a belt pulley?! mounted on onset the shaf s 8; com nected by belt to. sin-electric motor 25 having the driving pulley 2'5 thereon. It will be der-. stood thatinstead or using a, belt and pulley arrangemen fordiivins'one ofthe shafts, a clcieinv drive or directdrive for the shaft could be used and instead of an electric motor any suitable drivins means couldbcemp oyed. I
I have illustrated the device without indicatin anyspring suDPQrts forthe box althou h. these might beused. it beins nly necessary that the. box be agitated sufiiciently. to. move the balls run the mechanism at .froml to. 300 revolutions p r minute depend-mention the work to be done and provide eccentric shafts 8 which. give a. throw ing stroke of from. 1 to 2. inches. It will berunder- 86. without interfering with the operation. of the device materially. 1 i
Extending transversely of the box are Darth tion members. I which divide the box into. compartments or sections. and extending from the. p of the. partition H upwardly and at an angle are foraminous elements [5, The elementsv [5 are supported at their tops by cross members It. one of which is located at the open end 5 of; the box and serves also as a; stifiener.
In each compartment formed by the pertitionv members ll are a plurality of balls H. These balls may be of any suitable material, and also. in referring to them as balls... itwill be understoodthat they can be of any suitable shape o h than round, it being only essentialthat they be adapted to crush the objectionable material in thesgrevel as it is agitated with them. I
.The. 'foraminous elements. ii. can be. of any. desired type but I have illustrated a plate having.
Kill.

ready for shipment or immediate use.
holes [8 therein. These holes are of a larger size than the gravel to be treated so that the gravel can pass freely therethrough, and the balls are of a larger size than the holes so that the balls are retained'in the separate compartments to act upon'gravel as it is fed through the machine. 7
The foraminous elements l slope in a direction oppositetothe. slope of the box and ata greater angle, it being necessary that the slopebe such that the balls,'during the agitation, climb up on the compartment. v v v In construction of the box I,"I prefer 'tojprovide Wear plates IS in the bottoms of the compartmentso that wear on the surfaces'will not destroy the machine, and the plates can bereplates could also be provided on the sidesif desired.
In the' bottom plate3 at the open end 5 01 the.box,-I provide 'a series of openings 20 which serve as a gravel scree'nand Iprovidea water sprayer 2| for spraying the gravel as it comes from the machine towash the broken'stone and clay through the screen; The gravel is passed to suitable collecting means, If desired, the holes 20 may be left out and a separate screen may be 'provided. At the hopper discharged-3,
I may also provide a watersprayflfl'to spray is sufficient to cause the balls and-gravel'to be thoroughly mixed and agitated together and the crushing action of the balls is suchthat the rotten stone and clay lumps or the 7 like are 1-broken up and the gravel passed through'the" screen. "The mixture*ofthe gravel and balls rides up on the foraminous element l5 and thecrushing action of the balls forces the gravel through the screen and assists in breaking up; the objectionable materials 'The angle'of the foraminous elementl5 is such that the balls are kept down at or near the compartment and the crushing action of them is assured. I have shown three compartments but it is obvious that if de-- 'z sired morecompar'tments' could-be supplied, or
if the work is light, fewer compartments would do. As the gravel passes over the openings" the spray'of water 2| washes the'gravel'and it It. will beappreciated that this machine is of a very cheap and'simple-construction and can be transported and- 0 rated on the job if necessary.
in an embodiment which hasprovenfhigh'ly satisfactory. I have notattem'pted to illustrateanddescribe variousother adaptations or embodiments'which I contemplate as it believed that this embodiment will-enable those skilled in the art 'to embo'dy or adapt thesame as may be desired.
