Tofall whom t may concern:

Be it knownv that I, JAMES M. LONGAN, a` citizenV of the United States,iresiding at Chicopee, in the county of Crawford and `State of Kansas, have invented a new and usefull Ore Washer and Separator, 'of which the followingis a specification.

`The present invention relates to ore washers, `separators and concentrators, and aims to provide a novel and improved machine forwashing various ores and separating the same from dirt and slime, in a thoroughly practical and efficient manner and with a continuous operation;

` It is the objectl of the invention to provide a machine embodying a plurality of washing and concentrating pans or boards, and novel means for mounting the same for movement past areceive'r or receivers for the discharge of the orev thereinto, the pans or boards being! agitated to concentrate the ores therein.

A further object of the invention is the provision of a machine of the nature indicatedv wherein the pans or `boards are mounted for circuitou's movement to provide for 'a continuous operation, the unwashed ore being'delivered onto the machine at one point, and water being supplied thereon at another point, so that the washing andseparation take place as the pans are moved in succession to the receiver to discharge thereinto.

'Iheini'fentionl also has for its object the provision of ancre washer and separator of thenature indicated embodying a novel assemblage of the component elements and novelactuating mechanism, whereby the operation of the machine will be carried out in a satisfactory manner, under various conditions.

With the foregoing and other' objects'in view, which will appear as the description proceeds, theinvention: resides in the combination and arraiigementof parts and in the details of construction hereinafter deL scribed and claimed, itbeing understood that changes in the lprecise embodiment of theinvention-herein disclosed can be made within the scope ofwhatis claimed, without departing from the spirit ofthe invention.

The inventionis illustrated in the. accom# panying drawings, wherein:

Fig. 6 is an enlarged detail view of" one of thev catches. f

Figs. 7 and 8` are plan views ofmodi'ed forms of pans or boards usedwithlditferent ores.

The machine embodies a suitable base l above which is disposed an inclined supporting frame 2 having its lower end hinged, as at 3,t'o\the`base in order that the frame can be supported at various angles to suit various materials and? ores. The upper end of the frame 2 is supported by propsV 4e or other suitable means from the base. l

The shaking or agitating frame 5' is mounted on the supporting frame 2 inf a 'similarly inclined position for transverse vibratory movement, and this shaking frame embodies transverse cleats/or bars `6 seated on the frame.` 2, and longitudinal side bars 7l securedon the cleats 6. The cleats 16 have recesses 8 accommodating the side bars of theframe 2, permitting theframe 5 to have a limited transverse movement. The'frame 5 rests against a transverseplate 9 secured upon the frame "2, thereby preventing: the shaking frame from'slidingdownwardly on the supporting frame.

In `order to shake the frame 5 transversely, reciprocatory bars; 10 are carried by the frame 2 at the opposite' sides thereof and are provided at theopposite sideswithreversed cams or wedges 11` working in the recessesS, and the-cam bars 10 'are connected byf links or connecting rods 12 with cams or eccentrics 14 mounted on a transverse drive shaft 14 carried by the frame 2 near its upper end. Thus, when the driveshaft la is rotated, the connecting rods 12-will reciprocate the cam bars 10,- thereby'actuating the cams or wedges 1l-which vibrate or `shake the frame 5 transversely and parts carried thereby; 4

'The side bars ofi theA frame. f5 areprovided with upstanding longitudinal guidesl for the ends lofthe transverse elongated washing and separatingboards 'or pans 17g which can be constructed of wood or other-suitable material. As illustrated, said pans are each of wood having on the upper surfaceV the sheet metal plate 19 provided at one edge with an outwardly curved lip or riiie 20. The ends of the pan or board are provided with tongues 18 of reduced width to work in the guides 16 with the riiile 20 of the pan at the lowermost edge'thereof. The riiiies 2O of the pan serve to retain the oreor heavier material within the pans, but permit the dirt land lighter materials to be washed from one pan to another with the water as it flows downwardly over the series of pans, the rililes 2O also overlapping the next lower pans to discharge ythe materials from one pan to another toward the-lower end of the machine.

As a means for giving the pans a greater inclination transversely thereof when they reach the upper end of the shaking frame on which the `pans move upwardly, guides or railsy 21 are pivotally connected by links 22 or otherwise with the frame 5 near the upperend thereof, and extend over the upper end of said frame, being arranged at a greater angle of inclination relative to the base 1, and at an acute angle with the frame The upper ends of the guides 21 are adj ustably supported by adjusting screws 23 carried thereby and resting on the frame 5, or othersuitable means can be used for adjusting said guides. yThe frames 2 and 5, as above explained, can be adjusted to different angles of inclination due to the hinging of the frame 2 to the base, and the guides 21 being hingedly connected with the frame 5, can in turn be adjusted at various angles of inclination relatively to the frames according to the materials being worked. The guides 21 extend upwardly at an angle from the upper ends of the guides 16, so that the pans 17 as they are moved upwardly, move fromthe guides 16 into the guides 21, and in doing so, will begiven a greater angle of transverse inclination longitudinally of thefmachine, to. dump the ore into the receiver, as will hereinafter more fully appear. The guides 21 have grooves 24 for ren ceiving the'tongues 18 of the pans and said guides have cut-away portions 25 permitting the tongues 18 to move downwardly, whereby to transfer the v pans to the returning device.v The pans when they are moved between the guides 21 `have their tongues 18 moved over cleats 26 carried by the guides beyond the recesses or eut-away portions 25,thereby supporting the upper edges of the pans until the tongues 18 are in a position to move downwardly, thereby causing the lower edge of the pan to drop, as seen in Fig. 3, while the upper edge is supported on the cleats 26'. l

" The returning device' for the pans embodies endless belts 27 trained around pulleys 28 carried by the upper end of the frame 2, as at 29, and also trained around pulley wheels 30 carried by a transverse shaft 31 journaled to the frame 2 at the lower end thereof. The upper runs of the belts 27 move downwardly underneath the upwardly moving set of pans carried by the shaking frame 5, so that when the uppermost pan drops downwardly from between the guides 21,it seats on the belts 27, which convey the pan downwardly underneath the active set of pans to the lower end of the frame 5, where the pan is limited in its movement by suitable stops 33 carried by said frame.

The pan which is returned to the lower end of the frame 5 is transferred back into the guides 16 at the lower ends thereof, by means of a pair of longitudinal lift bars 34 slidable longitudinally on the cleats 6 within guides 35 thereon, said bars 34 being provided with cams 36 to move onto the cleats 6 when said bars are moved downwardly, thereby raising said bars. Said bars are normally slightly below the plane of the upper runs of the belts 27, but when said bars are moved downwardly and raised by the cams 36, the bars are raised above said plane. The pan at the lower end of the machine which rests 'against the stop 33 will, therefore, be raised by said bars into the plane of the guides 16 for upward movement into said guides. The bars are also raised at their upper ends to receive the pan which passes from between the guides 21, as explained more in detail hereinafter. These bars 34 form a part of an intermittently reciprocated trip or actuating mechanism embodying a transverse bar 38 mounted for longitudinal movement of the machine below the frame 5 and above the frame 2, and connected by links 37 with the bars 34 to reciprocate said bars. Cords or other fiexible elements 39 are connected to the bar 38 and exl tend over guides 40 at the upper end of the frame 2 and have suitable weights 4l suspended from their free terminals, whereby the weights normally move the bar 38 and parts connected therewith upwardly to normal position when released. The bar 38 and parts connected thereto are moved downwardly intermittently by means of cords or other flexible elements 42 connected to said bar and to a transverse winding shaft 43 carried by the frame 2 for winding up the cords 42, whereby to pull the bar 38 downwardly. This shaft 43 is provided with a star wheel 44 thereon disposed between the belts 32 which connect the shafts 14 and 31 to drive the belts 27. The belts 32 are connected by a series of transverse cleats 45 providing a rack to mesh with the star wheel 44 and rotate the shaft 43 to wind up the cords 42 once during each circuitous movement of the belts 32. Thus, when the cleats 45 pass the star wheel 44, the shaft ITO meneer 43'zis' rotatedito` wind up` the cords 42, thus pullingthebar 38 and arts connected thereto downwardly, and after the cleats 45 have passed the star wheel 44, the bar` 38 is released, so that the weights 41 pull it back to normaly position. i

Upstanding `plates 46 are secured. to the endsfof the bary38 and have connected theretolinks 47 extending behind therlinks 22 and connectedat theirupper ends to a transverse strip 48 sliding'onthe guides 22. rThis strip 48 isreciprocated with thebar 38, and assists in the removal of the pans from said guides. A transverse bar 49 is secured-upon the plates 46 above the guides 16 and frame 5, and have. secured thereon a` receiver or. collecting pan 50 which has its` upper receiving edgeso arrangedas to move below the riflies 20 in succession as the pans are fed up wardly. The receiver 50 has a discharge spout.. 51 extending to one side.

As illustrated, a singleA receiver is employed, but4 it will be readily appreciated that a number of receivers can `be used side by side, or at different positionswhen a multiple separation of the ore is desired. Various forms of pans can also be used, according to the material being worked and other conditions. The pans shown in Figs. 1 and 3 are of simple or plain construction for ordinary use, whereas the. pan shown in Fig. 7 is provided with oblique corrugations 60 and partition or separating cleats 61, for use with` certain kinds of material, when the acf tion of the corrugations adds efficiency to the operation. It will be noted that the corrugations will serve to direct the ore transversely of the machine during the shaking and` upward movement of the pan, whereby to dischargethedesired ore into the receiver. The receivers can, therefore, be of restricted width, as seen in Fig. 1, to receive theores from one point 0f the pans only, thereby providing for a more thorough separation of the material. Fig. 8 illustrates still another form of pan having the cleats 61 and drain apertures 62 adjacent to the riiiies 20. These and otherforms of pans can be used as required.

In order to move the pans upwardly on the shaking frame 5, bars 52 are secured to the bar 49 and extend downwardly along the guides 16 `over the tongues 18 of the respective pans, and catches 53 are pivoted-to the lower ends of the bars 52 to drop intoengagement with thetonguesv 18. Said catches are reciprocated baclr and forth with the bar'38,.whereby when the bar 38 is moved downwardly, the catches 53 will engage the tongues 18 of thepan which is raised by the lift bars 34, the return movement of the bar 38, therefore, moving` the lowermost pan withthecatches 53 upwardly intothe guides 16, thereby advancingjout of the pans on the shaking frame. Catches` 54 arencarriedby the shaking frame near the lowerend thereof, to: engagethe tongues 18 and prevent the downward movement of the pans,` especially when the bars 52 are* moved downwardly. The bars 52 work under guides 55 carried by the'frame` 5, `while the catchesV 54 work under guides. i

The* operation of the machine is as follows: The materialr to be' separated is delivered. onto thepans at the lower `portion of the machine in any suitable manner,an`d water isA sprinkled or otherwise supplied onto the pansv to wash the dirt and lighter materials downwardly. During thel operationfof'themachine, theV camibars 11 will be reciprocated continuously by the rotation of the cams 13 with the shaft 14thus shaking the frame 5 transversely. This will shake the pans longitudinally of them selves, whereby to facilitate the washing of the lighter materials from the ore, which concentrates in the pansadjacent to the riffles, serving to retain the ore. The water and` lighter materials will flow from one pan to another over the rifHes downthe machine, thereby washing the ore. rlhe pan 17 which is in the guides 21 is arranged at greater angle and its riiiie overhangs the receiving portion of the receiver 50, sothat the ore will bedischargedfrom said pan into the receiver due to the transverse movement of said pan, the lighter materials having been previously washed from said pan during its upward step by step movement. At intervals, the cle'atsor rack 45 of the `belt 32 will engage'the star wheel 44 and rotate the shaft 43 to wind the cords 42 thereon, lthereby moving `the bar 38 downwardly, together with the links 47 and strip 48, bar 49V and receiver 50, and bars 52 and catches 53. During such downward movement of the bar 38, the bars-34 are also moved downwardly, whereby to lift the empty pan at the lower end of the machine, which has its tongues 18engaged by the catches 53. The receiver 50 in being moved downwardly, will `have its receiving edge moved past and under the riilie 20 ofthe next pan. Now, when the cleats 45 `have moved past the star wheel 44, thus releasing the bar 38, said bar is re turned upwardly by` the weights 41 or equivalent means. rlhe catches 53 being moved upwardly will carry the lowermost pan with them into the' guides 16 from the bars-34, and the lowermost pan will push the other pans ahead of it upwardly in the guides 16 and 21. The receiver 50 also moves upwardly with the pans, and the strip 48 which 'was previously moved downwardly along the guides 21 over the pan17 which previously discharged into the receiver, will move upwardly with said pan as the pan moves over the cleats 26, thusholding the pan on the cleats'26momentarily, until the tongues 180:15 Athe pancan drop through the cutea'way portions 25. The lower edge of the pan, therefore, drops first, as seen in dotted line in Fig. 3, onto, the bars 34:, andthe strip 48 passes vover the upper edge of the pan ofl' of the same. vl/Vhen the parts have returned to normal position, the bars 3A in being lowered let the lower edge of thev dropped pan rest on the belts Y27 which carry the pan downwardly to the stops 33, said pan being cleaned out since the ore was delivered to the receiver, .and the dropping of the pan will also further clean it out. The pan which is moved aheadof the receiver in moving from the guides 16 into the guides 21 will be given a greater angle off.. inclination, thereby assisting in the discharge of ore into the receiver in addition tothe transverse shaking movement of the pans. The

Vtransverse shaking movement of the pans is continued in the meantime, andthe pans remain in 'their longitudinal'` position until the cleats A5 again .engage the star wheel 44, when the operation is repeated as before. The pans move through a circuit, being moved upwardly in a seriesl to and past the receiver, and then returned to the lower'` end to again be moved up in regular order. This providesfor a continuous operation of the machine, and a steady flow of material can be delivered onto the machine. Each pan during its shaking movement is fed upwardly step by stepeto `finally discharge into the receiver, and is then returned' back to receive another supplyv of material. The pans move upthe incline during their shaking movement, whereby the lighter mat-erials are washed downwardly from one pan to the other to be discharged from the lowermost pan. After the dirt and lighter materials Yare washed from the ore, the ore is discharged into the receiver, thus completely emptying they pan automatically, whereby there is neither yan accumulation of ore nor waste material in the machine.l Consequently, the machine need not be stopped for cleaning, and the separation of ore will be uniform, due to the fact that each pan is a unit in itself, .first receiving the material, then having the dirt and lighter materials washed therefrom, then discharging the concentrated ore into the receiver, and then returning back to positionV 'to receive more material.
