- Be it known that i, FRANK Nicnmn, e citizen of the United States, residing at Seronton, in the county of Laokawennn and Stets' of Pennsylvania, have invented new and usefoi; ininrovements in Spiral Sepuretors, of
which the following is n specification. This invention relates to that (dass of sepatutors for coni, &e.,.emhodying Yc. vertical spiral way or channel wherein the oro or nia# 4'tcriui fed in at the top is seperated by eentrilfugni action and by gravitynnd friction in 'Q4-its traverse down the spiral wey or channelles, for instance, in the Pardiae type of sopai5` rators.

A further object of the invention is to increase the frictionel Aaction between the spiral wey and the heavier ports of thv motorini treated.'
A further object of the invention is to pro the speed of the nmlorinl treeted overithc lsoor of the spiral wary, thus ennliiing thc some machine to succcsslfully handle ores, like., varying greatly in choreoter and requiring diierent treatment. V
W'itli' thse objects in view the invention consists in details of constructionnnd combinotions, which will be `described in the ensuing s eficetionand claimed in the clauses nt the c ose thereof.
In the accompanying drawings, Figure 1 is e vertical section through a' rotary separator Fig. 2 is n lside elevation'of the seine. Fig. 3 is n plan view showin the d rivinfr'connection between the source o? power nm the sepnrntor-shnft, whereby the rate of rotation/of theseparntor may bereguined to snit thc conditions nl' tin.' material trratcd. Fig. i isn doluil ofthedstrihuting-hin.
Referring now to the drnwings, 1 dcsignotes the vertical rotnry shnft of :ny iniproved separator, the saune comprising` in' the instance shown o tube or )ipo provided nt its up )er and lower ends with ane-tid stubs etwccn which the tulle is provided with n filler 4, of wood, to give rigidity lo ther Ilshnt nod to nli'ord anchorage for t 1o'suprafting-unos of the spiral ways, presently to lie described. The shaft l is at its lower end inonntedin n step-houring 5, suitably secured to nli'ord the required stability, and l prefer to einpioy n hull-bearing nt this pond-,z shown, to receive the thrust of tho s mit nml to reduce friction. A v
The stnh 2 nl the upper und oi' tho sind'Ll is holi'ow und is secured rigidly to n shnft (i. ournnled in suitably-suppe:rtm1 hrnrings 7 and provided ut its upper ond with n horn! geur-wheel H, meshing with 1|. corresponding pinion i), carried hy n. counter-simil, l0. 'This V,vomito[-sluilt; is provided with u pulley Il,
Vwhich is nonno :ted by heit l2 with n pulley' 'i3 on tilo'cnd of one ol' o pair of pumllol snifts 14 I4", eurryinfr oppositely-tapered cones l5 i5, operative y or frietionelly connected hy n ring 16, shiitnhle longitullinnlly of the cones, so that the rotation of thol dliving-cono which is driven et. n constant s eed troni any' siiitahlc source of power tlirough pulley 17, will impart c(irrespijniding,Y rotation to the. cone l5 and thence to shaft l at "renter iii-less speed, accordingr iisthc ring lt is shifted to one or the. othersiileol the. longitudinal centers ol" the nies. 'lhis changespecd device is of taniiliiir construction and forms no piirt of nii' invention except in coinliiinition. As the iiiiiteriiil to lie operated upon dillcrs greatly :is to its spceiie gravity in diflcreiit inines and in ilillereni. veins in thc saine. mine it liecoines necessary to the accomplishment ol perfect work that the inzichine should he equipped willi means atthe o erators disposal to regulate the speed :it W ich the machine is'riin; llence .l eniplov the speed-regulating incans described, though an other that will accomplish the saine cnd wi l answer the purpose.
Secured rigidly to the shalt 1 arc spiral troughs or ways A A and I3, e-.ich comprising what I shall terni :i lloor" A anilB and a. wing" A: and BL'. The spiral ways A A extend troni top to bottoni ot' the shaft, and at top the vertical ings A: thereof constitute a hop iena to receive eoiil from ii suitable chute lleatling from ii lireiiker or grader. These wings are gradually reduced in height, (sec Fig. 1,) terminating approximately in a horizontal plaine with the upper end ol the Way B, froni thence downward to the distributing-hin l). At the lower enil ol' the separator the ways A A comprise the lliior A' and its supports. The spiral wii l is of greater dianicter than the ways A A, its I'nne` tion h ein,1 to receive con] discharged li) eentrilugiil l'oree. leoni the ways A and convey it to :i distributing-hin lll. The upper end of this `way B is located appioxinnitely in a 'horizontal plane with the lerniinution ofthe wines A: ol' the wiiys A A\ to receive eiiiil, tie., disc iiirged l'roni the outer edge thereof, said way B havinnr n llooi Bf, having ii pitch toward the shii'ltY of, say, forty-live degrees, as shown, and n wing l", having :i 'gleeter incline with relation io the lsluiltf-siiy eighiydegrecs, niore or less. 'llhese ways are, sup- ,ported on the shaft l lijir means of arms 2U 20" 2U", pinietriiting the ftiiliuliir shell thereof and havinpr anchorage inthe wood or olhei filling 4, heretofore refiiired to'. 'lhc ai'nis 20 and 2U are lient at angles lo aeconiniodato and properly .support the parts of the several ways to which they iiie appropriate, relerenee living had to the drawings. l`lie ways A A and B extend to near the liase oll the shaft l, where they discharge the separated coal and shite into a hopper It), lending 1o chiites 2li :ind 2l, the loriner tiiliinpr the slate, and hone 'roni llie ways A A and the hitler taking eoiil l'i'oni the way li De- Ileelorplates rl und /i iire seeureil :il llio lower ends ol' the respective wars :inil B to give propel' direi-tion lo the iiiiileiiiil :is it is iliscluiigcd.
By employing a rotary sparator I ani naliled to olitain nnich more effective centrifugal action in the separation of the coal and slate, and, moreover, I am enabled to construct the spiral of more rapid pitch than has heen heretofore possible in iincfl'ective separator, since while the shite arid bone traverse the inclined ways more ra'pidly the friction thereof upon the floors A and B will be ini creased as these floors travel in the direction of the feed of thc material. i
The foregoing' is aV description of the spiral ways A and B, respectively, while in order to increase the capacity or usefulnessV of n inneliine in practice I increase the spirals saine description, leaving the spiralway B iis one, sciving as a catchingan4 of coal for all the three or four spiralsA It has been only after long and careful experiinent that I found it to be of great. benefit to run the spirals in the direct-ion of the feed. This operation is substantially like that of pushing the bottom spiraliundcr the running coal, or equally of havinu less' pitch, Besides I get a use of the centri iwal tcndonc'y in peeuliiir iiiiiiiiii-rtliiit of thaving;r the material rundown li action of gravity and at the saine time eliinli the incline from the center of the spiriiltothc side of the same, and as the slate or rock is much heavier than the eoiil, or at least very iippreciably heavier, the slate or rock hy means of the centrifugal tendency will soon be ahead in climbing thc ini-line l'roiii the center to the side of the spiral :ind drop oil" into an attached catchingpiin. as has heen ascertained from careful cxperiinentiition. Now it has also been ascertained from the latter action that coal is not only of dill'crent specific gravit-y in different mines, lint of varyinpy gravity from differenti veins in the saine niine. This fact makes it necessary to adjust the spiral separator at will andv immediately, so as to change the speed iitwhich it is run. This I accomplish, as I have already stated, hy intcrposing an Evans friction-coneI 'or speed-changing means between the spiral separator and the powershalt. ll tliisspecd-ehnnging1neans,wliich may lie o any form that will accomplish the purpose, I eini treat any reasonably-sized maiteriiil or material of varying gravity with equal effect. and with the greatest recision and highest degrecof erfeetion. T -send'conld not be olitained ift ie machine were notrendered capahle of changing its speed as stated. I of course niiike no elniin to speed changing nieiins per se, hut only to its employment in this particular combination.
