To all whom t may con-cern.' f

Be 'it known that I, JAMES F. RnILnY, a

citizenof Canada,fresidingat Tucson, inthe vcounty of Pima and State'of Arizona, vhave invented certain new and' useful Improvements in Combined Jigs and Aspirators,f`of

which the following is a full, clear, and exactl description. y

`The invention relates to a combined jig and aspirator for separating the gangue from the heavier particles ofthe ore and one of the objects of the invention is to provide an apparatus of this character which is simple in construction and which is easily manufactured and installed, and which will ae-v complish the desired function in aA high-ly efficient manner. Y

It is well known that the 'escaping dust has a very injurious effect on the operators in ainill; and one of the object-s of the present invention is to Aprovide an apparatus in which all' of the operations are effected within a closed casing 'so-that all escape of the gangue to the atmosphere 'is prevented. l

A further objectof the invention is to provi de an apparatus whichrwill more thorouglily separate the gan'gue from the heavier particles thanhas been possible in previously known constructions; and w-hichwill automatically classify the particles according to their weight and deposit them inseparate receptacles.

adjustable f for varying the amount l[of crushed ore which is fed from the hopper` tothe separating apparatus. A. simple con.- sti'uctio'n-for accomplishing the vertical fade liustment ofV this combined element' consists in providing the vertical plate with a rack* 3 at-each end! thereof, and meshing-with each of these -rachs isa pinion affixed on a rotary' l This shaft "extends outwardly through one wall of th-e .casing 6l and has a 'worm wheel 7 Ymounted on its outer end-g2 the worinwheel being engaged byvworm S opcrated'by hand wheel 9. As'plainly indicated in the drawings, particularly Figure 4,

the. shaft 5 where it extends. through. the casing and the associated parts for rotating the shaft are all i'nclosed for the purpose of preventing the escape to theatmospheie of the dust 'within the casing G.

rMounted within the-casing and bel'ow thelcliute Q, is a transversely reciprocable jig 10. The is-supported byl a suitabley number o'f spring'elements 1I extending upward'ly through thetop of the casing and adJustably mounted by means of vset screws '12. For the' purpose of steadying the spring elements and adding strength thereto, they areA passed through blocks 11.', clearly shown in Figures 1 and' 2. `I TheA jigis `given a rapid transverse yreciprocatory movement -by 'an apparatus to be hereinafter described.

it l istprovided: with a" depending strapl 2- whichis adaptedto be engaged' bythe end ofthe .vibratory jig-10. It willbe under-1 stood, of course, that the chute 2 is loosely mounted in order that it mayv have a vibra.- tory motion imparted to it.

Arranged in the casingG forwardly of and below the jig 1'0 is a second jig 1S which is Nuineral'lli indicates a pulley whichis driven by a belt 15 from anydesired source of power. Thispulley `14 operates a'cone pulley- 16 arranged in the .usual relation' Itgis also the intention to give a vibratory n I `motionto the chute 2, and for `vtl'ia'tpurpose f with an opposite cone pulley 17 mounted on a shaft 13; the two cone pulleys being operatively connected in the well. known manner by a belt 19. Also mounted on the shaft 18 is another pulley 2O carrying a belt 21 which engages a pulley 22 mounted on an inclined shaft 23. The inclined shaft 23 carries two eccentrics 24, 24 associated with eccentric straps 25, 25; and these eccentric straps are pivotally connected to links 26, 26 which are attached to the jigs 10 and 13. The links 26, 26 are mounted in bushings 27, 27 at the point where they pass through the wall of the casing 6.

The vibratory motion given to the jigs by the apparatus above described will cause some o fthe particles of ore on the jig 10 to fall over the sides thereof into a chute 28 and be carried by a conveyer 29 to a receptacle 30. rllhe jig 10 is, of course, downwardly inclined, and as the material 1s v1- brated it will gradually work toward the lower end thereof where it will be fed upon a second jig 13. The ore fed to the jig 13 is subjected to the same vibratory motion and the material falling over the sides thereof will drop into a chute 31 and be carried by a conveyer 32 to the receptacle 30. The material that passes off the end of the jig 13 drops into another chute 33 which is provided in its bottom with a gate 34 which may be intermittently opened to permit the acumulated ore to drop through a conveyer 35 carrying it to any suitable receptacle (not shown). rlhe chute 33 is divided into two 'parts by a vertical partition 36 and vertically and adjustahly mounted above said partition 36 is a baille 37. This baffie 37 is made adjustable to regulate the character of ore which will pass into either side of the divided chute 33. Extending from one side of the chute33 is another chute 33 which will collect particles of ore from the jig 13 and carry them olf to a suitable receptacle (not shown) the chute being provided with an ordinary flap valve 39. EX- tending from the opposite side of the chute 33 is another chute 40 similar in all respectsV to the chute 38 and it will collect and carry oil to a suitable receptacle the crushed ore of another weight.

The motion which is imparted to the jigs in the manner previously described causes the very line dust or gangue to rise from the material on the jigs, and as this gangue rises it is carried off by a gentle air furnished by a blower 41. The mouth of the conveyer indicated by numeral 42 is arranged just over the top of the jig 10, and as clearly indicated in Figure 2, this mouth extends substantially the entire width of the jig. As the gangue laden air passes on through the casing it meets an adjustable baille 43 which divides the current into two parts. The heavier particles will pass beneath the baflie 43 and will drop upon either side of the balhe 37 depending on the weight of the particles.

The lighter particles will pass upwardly over the baille 43 and through a flue 44 into a separating chamber 45. As the dust laden air passes from the flue it will strike a baffle 46 and be caused to rebound, and it will thus be given a whirling motion, whereby the heavier particles will settle. These heavier particles will pass downwardly through a passage 47 into a chute 33 where they will be accumulated. The lighter particles will continue their upward passage, and arranged at the top of the separator chamber is -a suction fan 48 which will carry oil these lighter particles and force them through the pipe 49 to a settling room (not shown). Any particles which settle before reaching the suction fan will be caught by the circular baille 50 and be directed into appropriate chutes 51 to suitable collecting receptacles not shown).

rlhe entire side walls of the casing 6 are made removable and are held in place by clamping screws 52, as clearly shown in Figure 2. rllhe side walls are also provided with appropriate peep windows 53.Y

lt is believed that the operation of this apparatus will be thoroughly understood from the foregoing description, but it may be brieliy deseribedas follows:

rlhe principal object of the invention is to separate the gangue from low grade lead and copper ores where more than 60% of the material to be separated is gangue and waste matter. Material is fed from the hopper 1 onto the chute 2 which chute is given vibratory motion by means ofthe vibrating jig 10. rthe material is thus caused to pasg from the chute on to this jig. As the jig vibrates laterally some of the material may be thrown olf the sides thereof;V or it may drop. through holes which may be pro vided if desired in the bottom of the `ig 10. Also the air supplied by the blower 41 may cause some of the ore to fall off the jig 10. All of these heavier particles which fall from the jig 10 will be collected in the receptacle 30 in the manner described. Material passing olf the end of the jig 10 passes on to the jig 13 where it is treated in eX- actly the same manner, and any heavy particles falling off of this will also be collected in the receptacle 30 or in a separate receptacle. The particles passing ofl the end of the jig 13 will pass into one of the compartments of the chute 33 or into the chute 33 or 40.

llhile the material is being agitated on the jigs 10 and 13 the gangue will rise therefrom and be carried off bya light air furnished by the blower 41. As shown in Figure 1, the mouth of the blower is arranged directly over the top of the jig 10,

imV

'andas shown in Figure 2, the mouth of the blower is of substantially the same width as the 'j'ioz f The gangue laden air will pass on to the baille 43 where the heavier par* ticles will pass downwardly for collection while the lighterparticles will pass upward- .ly through the flue 44 into the separating chamber 45, where the heavier particles will' be Jfurther divided out in the manner described, and the lightestparticles will be carried on through the pipe 49 to a settling room (not shown). i

, It is to be particularly-noted that every element in this apparatus is inclosed,A and that the construction is .such that it is impossible for any of the dust to escape from Y' the apparatus into the mill, and this pre- Hthe scope of the appended claims.
