To all whom it may concern.

Be it known that I, DANIEL R. BRYAN, a citizen of the United States, residing at Uhath am, New Jersey, have invented certain new and useful Improvements in Apparatus for Sorting Heterogeneous Material, of which the following is a specificat1on.

The general object of this invention is to refine the construction of an apparatus for sorting heterogeneous material, such as that which makes up the refuse of cities and consisting mainly of ashes, cinders, paper, rags, glass articles, metallic substances, etc, and. especially that type of apparatus as shown in U, S. Reissue Patent No. 14,266, dated March 6th, 1917. In that apparatus it has been proposed to employ rotary screen members having graduated openings and a stationary inclined chute to receive the mass of material after the same has been operated upon by the screens. I have now found that the efliciency of the structure forming the subject matter of that patent may in no wise be departed from by the substitution of a, reciprocating screen and a vibrating table arranged so as to receive the material after it has been operated upon by the screens. In fact, by the substitution of these new elements, the apparatus is rendered capable of operating extremely efliciently on certain'grades of material. and at the same time the cost of mamifacture is greatly reduccd.

Other objects will appear and be better understood from that embodiment of my invention, of which the following is a specification, reference being had to the accompanying drawings forming a part hereof, in which.

Figure 1 shows a longitudinal vertical section with. parts in elevation. Fig. 2 shows a horizontal sectional view of that portion of the apparatus in which is located the segregating mechanism, and Fig. 3 is a cross sectional view'taken on the line 33 of Fig. 2 with parts shown in elevation.

In the drawings A. designates a casing, B a reciprocating screen provided with a series of holes of relatively ditfereut sizes, and C a chute preferably rectangular in cross section and to which the material passes after being acted upon by the screen.

The screen may be mounted for reciprocation in the bottom of the casingin any suitable manner. As here shown, it is provided at each end portion with crank rods D and E, which are connected to the crank shafts I.

Through chain and sprocket connections (it with an electric motor H the crank shafts are rotated.

The screen is preferably formed of one continuous sheet of metal and is preferably divided into three sections, namely a F) c, in which the relatively difl'erent sized holes are located.

The casing is preferably provided at its upper end with a hopper I into which the material to be sorted is dumped. and which delivers the same to the screen as shown.

An adjustable gate or door J is provided within the lower end of the hopper for the purpose of regulating the iiow of material to the screen when desired.

In the upper end of the chute is preferably arranged a means for removing the clouds of dust and fine particles produced by the screening. operation. As shown here, i have employed practically the same means as disclosed in my earlier pz.itentnamely, an electric fan I: which produces a current of air in a conduit is which acts by inspiration, through orifices Z and. m over the screen,- to draw the dust-laden air from within the chute into the conduit and carry it away, to a bin or receptacle hereinafter referred to.

lilatcrial passing from the hopper onto the screen. isugitated thereby and the screen being provided. at its section a with smali pcrtorations, is partiaily sifted and such particles as ashes and other fine particles removed therefrom. From the z' material passes to the section I) where it again further sifted. The section F1 provided with larger nzriorations than the section (6 and such pa .ts ot' the material as small cinder-s or other particles may be removed. From the section 1') the material passes to the section 0 where it undergoes further agitation and. sitting. The section havinglarger perforations than the section 7) operates to remove the larger particles from the mass. A suitable frame L is also provided for the purpose of supporting the chute and casing at the proper inclination.

From the screen 13 the material passes into the chute C, and a swinging door M, adapted to be held in adjustable position by means of a rack and dog N ,may be provided for regulating the passage of material to the chute. The sifted material, which is separated by the several. sections of the screen, falls into a series of funnels O, P, Q, arranged beneath the screen and is delivered into separate bins or compartments, R, S and T where it may be collected. After the screen has acted upon the material, it is then discharged onto a vibrator which forms the bottom of the lower portion of the chute. The construction of this vibrator is best understood by ret'erence to Fig. 1 wherein its lower end is shown pivotally connected to the frame as at U and its upper end is mounted upon an eccentric V secured to a shaft \V.

Through a sprocket and chain connection X with the electric motor H the eccentric is rotated, whereby the operation of the vibrator is effected. By constructing the lower part of the chute as a vibrator admits of this part of the chute performing a two-fold function; namely, as a means for accelerating the movement of the material through the chute after the material has been deposited onto the vibrator as previously described; and also as a means for loosening lumpy material remaining unaffected under the action of the screen, or relatively light material that becomes deposited under the heavy. Thus it will be seen that the action of the vibrator on the material deposited thereon conditions this material to be effectively 0perated upon by the segregating mechanism shown in detail in Figs. 2 and 3 and which will now be described.

Referring now to Figs. 2 and 3, it will be seen that the segregating mechanism inchides a motor-operated tan 1 arranged so as to direct a. blast of air transversely of the vibrator. Thus it will be seen that when the material is conditioned by the action of the vibrator as previously described, the air blast generated by the fan will operate to remove the relatively light material from the, vibrator and direct the same into another part of the segregating mechanism, to wit 2-- a casing 2 which will he observed is disposed at right angles to the vibrator and in alinement with the fan 1, and leave the residue of material as a substantially thin layer or stratum whereby it is conditioned to have the metallic particles exposed for removal.

It Will be observed that the casing is provided with a series of chutes 3, 4.- and 5, opening at one end through the bottom of the casing and arranged one behind the other and viewed from a position looking, toward theright in Fig. 3. Thus it will be seen that this disposition of the chute provides that the relatively light mass of heterogeneous material removed from the vibrator by the direction of the fan blast and directed thereby into the casing will be separated according to the specific gravities of its components, that is to say, when the force ofthe blast is such as will move the relatively heavy components of the mixture to thefirst compartment 3 on the left in Fig. 3, gravity will operate to move these into the said compartment 3, while the lighter components will move forwardly under the action of the blast until the heavier of these coming into alinement with the sec ond compartment 4 on the right and. away from the influence of the blast, will .fall by gravity into the said compartment 4. The still. lighter components on coming into alinement with the third compartment 5 and out of the influence of the blast will gravitate into this compartment. Manifestly with this arrangement, greater or less num ber of compartments than shown may be employed as the character of the work demands. lVith a battery of three compartments as shown or more, any of these may be rendered closed or inoperative by means of a door (3 as shown in Fig. 3. The doors are arranged at the upper ends of the compartments and are pivoted as indicated at 7 and operated from the exterior of the casing by the handles 8.

The relatively light material which is separated from the mass and after passing through the chutes 3, 4 and 5, falls into a series of coinpartlmmts or bins Y where it may be collected.

As shown in Fig. 3, the mouths ol the compartments lie in an inclined plane in order that heterogeneous masses of different conditions, such as relatively wet and dry, may be effectively operated upon, the casing 2 is rendered bodily adjustable in a vertical manner. 'Any improved means for el'l'ccting this adjustment may be employmd but for the purpose oi illustration, l have shown the casing suspended from a davit E) mounted on top of the chute On the end of the davit is arranged a sheave 10 over which passes a wire cable ll, one end of which is connected to the upper end of the casing, the other end oi which after passing around a second sheave 12, mounted on the davit, is brought down to and wrapped around a clcat 13 mounted on the side of the frame ll, see Fig. where the end of the cable may be within convenient reach of an operator.

, From the point where it is acted upon by the blast of air, the material passes to a point where it is acted upon by an electro magnetic separator 14, the action of which is to separate magnetizable particles, such as ironand the like from the mass. As here shown, I have employed practically the same means for accomplishing this result as that embodied in my earlier patent, whereby inagnetizable material is separated from the mass and conveyed through an opening in the side of the clinic and delivered into a, bin or receptacle 16,.

After passing the elcctro-magl'letic separator such parts of the n'iass remain and consist mainly of bottles, particles of glass, etc, will be delivered through the end of the chute 18 into a bin or receptacle 19 Where it may be collected.

Each oi tbebins or receptacles is'preterably provided with a door 20 through which the contents may, from time to time, be remo v e d The usual means employed by me for antiscptically treating the material after it leaves the hopper is shown in Fig. 1 and comprises a tank 21 adapted to deliver a suitable disinfectant to the pipe 22 for spraying the disinfectant over the material as it vfirst the casing. 23-3 is also nro'viiled through which 30111 pressed ai admi ted to ti tank to force the disinfectant out from the pipe over the material to be will. be understood, the a iiparatus in disclose is operative to subject the xorial to assorting action bird. is traversing a flow path, being in approximate correspondence v1 h general characteristic divisions oi? the :uniterial, this action being provided. by the use of separating Zones located successively in such flow path and individually active to remove material of predetermined characteristics While. the material is traversing the zone, one of said zones, intern liate the ends ofthe flow path being ada iited to receive material and provide. a stratiiication of they material Within limits. to locate the lighter portions of the nmtcrial in an upper strata, said lighter particles being play in suspension by a pneu- "ic b t to carry the particles transversely iron] such path into a classifying cliamoer '"hin which the removed particles i classified curring travel to es, the chamber being of dimensions automatically decrease the preset the blast, so that the particles are lQlli'liP/l fl ui'ider maxinunn pressure and l modified pressure, thereby ification by specific gravling particles. obvious that those skilled in, the art tinny valv the i'lctails of construction and arparts Without departing from y invention, and, therefore, I do not w a be limited to such features, except as may be required by the claims.
