' the city ofDixon,

the machine is a pipe 1 passes, said pipe being 7 whereby the section on the line .the material to be reduced is The pipes 9 snrnna'rme nnvxcn.

To all whom it may concern:

Be it known that I, Enwann J. S'rncK'Ln, a citizen of 'the United States, residing at county of Lee, State of have invented a certain new an useful Improvement in Separating Devices, of which thefollowing is a full, clear, and exact description, such as will enable others skilled'in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part 01 this specification, in which-- Figure 1 is an endelevational view of my improved separatingapparatus. Fig. 2 is a side elevationalview of the same partly in section. Fig. 3 is a top plan view partly. in 3-3 of Fig. .2.

This invention relates to a new and useful improvement in separating apparatus designed particularly for'the. separation of particles of materlal reduced by some sort of reducing machine such as a crusher -or pulveriz'er, the object being ,to return the coarser particles of material to the mill for further reduction and to collect the finer Illinois,

particles as afinished product.

Of course the ribs 5 are separated at the hinge point, but are substantially continuations of the diverging ribs attachedto the solid portion of this flaring spreading pipe. The hinged, portion of the spreading pipe is-located in a chamber-8 in which chamber are arranged airinlet pipes 9 each having nozzles 10 whose discharge ends'arezflat ed-so as to'emit'substantially continuous sheets of air at. an angle to each other meeting practically at the lower edge of thefhinged portion of the angularly disposed spreading w with theirflattened mounted in the.

emitted therefrom can be adjusted. There *areremovable covers 9 on the ends of the pipes which enable access to be gained the interiors thereof from the outside for cleaning purposes. This may be necessary on account of the dust settling in the pipes 9. r The pipe 11 leads from thetop of the separating chamber 8 into the eye a fan 12 whence the dust laden air is projected by dust collector 13 of the well lmown cyclone type. The particles of dust thus drawn from the separating chamber by the fan are collected in the dust collecting chamber 13' the trough 14: in which is located a spiral blade15 for conducting the material into a chamber 16 where it may be elevated by suitable buckets 17 and deposited in a storagebin, not shown. e air pressure in the dust collector 13 escapes through a discharge pipe per controlled pipe vent 19 located at some suitable point in its length whereby ressure in the pipe 18 may be regulated. ipe 18- leads back to the separating chamber 8 and supplies air to the pipes 9 heretofore referred to.

Only the finer particles of material can be drawn into the pipe 11 any material passes with the air from the dust collector through the pipe 18, it is obvious that such dust laden air will be and deposited into chamber-an eventually be'collected. In heavy particles of material from being drawn. into the fan, I adjustable baflle plates 11 said lates being inclined in the opposite directions so as to deflect the air and cause the heavier particles of materi verted so that they will have an opportumty of falling back into The heavier particles, up through the pipe 11' fall into the bottom 0 the separating c 20, where a spiral 21 conveys or collectingchamber to be buckets 22 and returned by a suitable down 18 having a damby the fan and if the blower'tangentially into a order to prevent preferably arrange in the pipe 11,

The nozzles are directed so that the point of the intersection of the sheets of air emitted therefrom meet substantially at, or slightly below, the point of discharge or lower edge of the hinged wall of the separatspout. By, this arrangeing or spreadin "ment, I am enab ed to strike the fallingparticles-on both sides with the result that the finer particles are carried up with the air current and delivered to the dust collector. The troughs15 and 21 are so constructed that the screw conveyers arranged therein,

What I claim is: Y 1. A separating apparatus of the character described, comprising a separating chamber having a spreader for conducting the material posed nozzles for emitting blasts of air on opposite sides of the material as it leaves.

2. An apparatus of the character described comprising a separating chamber, a
