Specification of Letters Patent.

Application filed April 2, 1902. Serial No; 101.086.
T0 all whom, t may concern,.-
Be it known that l, RICHARD Go'rTIIlLF NEUMANN, a subject of the German Emperor, and a resident of Wandsbek, near Hamburg, in the German Empire, have invented certain new and useful Improvements in Concentrators for Pulverulent Materials, of which the following is a specification.
The present invention relates to concentrators for pulverulent materials of that class in which the pulverulent or finely-divided material is carried by a moving body of air or its equivalent through a zigzag-shaped or undulatedpipe-conduit or incasement provided with discharge-channels, and more particularly refers to means whereby the concentration or separation of the constituent particles of the material is controlled, the moving air freed from its admixtures, dust, tc., and supplied back as pressureless air to the centrifugal ventilator, or any other suitable lmeans forforcing the air through the said concentrator, so that the same bulk of air may be used over and over again.
Vtith this end in view my invention consists in certain novel features of construction and combinations of' parts, as will be hereinafter fully described, with reference to the aecompanying sheet of drawings, in which- Figure 1 is a side elevation, partly in section, of .a concentrator constructed in accordance with and embodying my invention.
Fig. 2 is a plan or top view of my improved concentrator, and Fig. 3 is a horizontal longitudinal section of the undulated concentrator-incasement of the casing for the centrifugal ventilator and of the collecting vessels for the concentrated niaterial.
Similar letters refer to similar parts 'throughout the several views.
l 0r shut up by swing-doors or turn-aps d, l hinged inside the serpentine casing b and operated by outside handles e. The said handles, and consequently the flaps d, maybe secured in the proper position by means of serrated segments p, fastened on the top plate of the serpentine easing, as this is evident from the drawings without further detailed explanation. When the concentrator is in operation, the turn-flaps are so placed that their vertical free edges are oppositely directed to the direction of motion of the material forced through the coneentratorcasing b. This position of the turn-flaps is shown in Fig. 3.
is forced by the action of the centrifugal ventilator a, to which rotation may be imparted by a pulley o through the serpentine casing b, whereby the material is thrown alternately against the curved vertical side walls of the casing or conduit l). The constituent particles of the material are according to their relative gravity and size driven by the air-blast for a more or less greater distance throu h the serpentine easing b, and as the turniaps d are directed opposite to the direction of motion or path of the said particles the latter are dei'lected or directed by the said turn-iiaps into the corresponding lateral discharge-channels c. The heavier or larger particles are thus discharged into the channels c nearest lor nearer to the ventilator, while the lighter and iiner or-lightest and finest particles `are carried and driven into the more remote and remotest channels c. The air-blast carrying the dust enters at the exit of the serpentineI conduit b into a suitable, preferably cylindrical, collecting vessel h. The diseliarge-channels c lead int similar collecting vessels q. Within the vessels g and' 7L the posited .and collected at the lower ends of lthese vessels into bags t or the like, while the oto., of the respective material escapes by vertical pipes g and h and connecting-pipes le, respectively, into a main pipe Z, through which the said air passes into a similar but somewhat larger collecting vessel m. In this latter vessel the air is freed from the last particles lof dust, &c.,' and relieved from any The material fed through a supply-pipe fy particles, dust, etc., forced therein are deair more or less freed from the particles, dustyv IOO pressure. The thus cleaned or purified and pressureless air is led back to-the ventilator or ventilator-casing respectively, throu h a pipe-conduit n, so that the same bulk o air rnayy be used over and over again.
i n the example shown the feed-pipe f discharges into the air-conduit n in front of the ventilator, so that the supplied material is sucked together with the air coming from the vessel m.
Although'it is preferred to employ for mau terials which are subject to spoilinr-such as Hour, grits, inely-ground cacao,andthe likeconcentra tor-casings having an undulated or serpentine form, in some cases, however, when materials less liable to spoiling-such as coloring-matters, brick-dust, &c.-are to be concentrated, concentrator-casings having a Zigzag-shaped form may be used with equally good results.
Having fully described my invention, what l claim, and. desire to secure by Letters Patent, 1s-' 1. In a. concentrator, the combination with an air-blast, of a horizontal serpentine-conduit connected at one end to the delivery end of said blast and 'at the other end to the suction end of the blast to form a closed air-blast circuit, discharge-passages from the conduit ing discharge-ports in its vertical walls, chan-` nels leading from said ports in the direction of the flow of air in the conduit, doors mounted .at said ports adapted to extend into the path of the current of air, collecting vesselsv 1n communicatlon W1tl1 said channels, and
air-passages leading from the collectors to the air-blast,l substantially as and tor the purpose specified.
3. In a concentrator, the combination with` an air-blast, of a serpentine conduit having verticalsides, connected atone end to the delivery end of the air-blast and' a pipe con- -nection between the other end of the conduit and the suction 'end of the airblast, thereby 'forming a closed circuit, a dust-collector connected tof/the said pipeand closed rece tacles connected to' the conduit to receive t e separated material, substantially as described.
4. In aconcent'rator, the combination withl an air-blast, of a closed horizontallyearn ranged serpentine conduit rectangular in l cross-section, a plurality of lateral discharge channels leading from the ports in the vortical Walls of the conduit and mounts-din thc direction of the flow of air, doors hinged at the mouths of said channels, means for adjusting said doors into. the path of the aircurrent, a collecting vessel communicating charge-channels leading fromI ports formed,
in the vertical side Walls of said conduit, said channels being mounted in the direction of the flow of air in the conduit, doors mounted' at the receiving 'end of said' channels, handles for positioning and locking said doorsint' the path oi the current of airin the conduit,
'a collecting vessel for each dischargeechannel, an-air-passage leading from 'the'top of each collectin vessel, a main passage vcommunicating with the aforesaid air-passage,v
and an air-collector interposed between said main passage and feed-pipe, substantially as described. V
6. in a concentrator, the combination with an air-blast, of a horizontal serpentine orjsinusoidal conduit having ports in the sides thereof and connected at one end' to 'the vairblast, a pipe connection 'betweenpthe 'other end of said conduit and the suction side of said air-blast,a plurality of lateraldischargechannels leading from the ports, and means to :individually control the opening of said" ports, whereby the particles foliowing first one side then deflected to the"'otl`1er side' of `said conduit will be separated in the order of their gravities', the heavier and, larger par-"' ticles passing into the discharge-channels nearer the'air-blast.
7 ln a concentrator, the'coinbination an air-blast, oi a serpentinelconduit h'avin'g'a continuous bottom and serpentine-or zigzag'E side walls having openings therein, adj'nstable doors to control said openings, and' means connected to the conduit at the open/ ings to receive the separated material, where` by the heavier particles will pass through the regv openingsnearest the air-blast, being moved first against oneI wall and then as described. l v
