APIPA RATUS FOR SORTING HE'IEROGENEOUS MATERIAL.

Patented June 9, 1914.

Application filed March 24, 1913. Serial No. 753,421

To all whom it may concern Be it known that we, DANIEL R. BRYAN and JOSEPH W. BRYAN, both citizens of the United States, residin at Ghatham, New Jersey, and 47 West New York, N. Y., respectively, have invented certain new-and useful Improvements in Apparatus for Sortin HeterogeneousMaterial, of which the to lowing is a specification.

This invention relates to an apparatus for sorting heterogeneous material, and aims to provide improvements therein.

The invention provides adapted to sorting and delivering to appropriate receptacles heterogeneous material such as that which makes up the refuses of cities and consisting mainly of ashes, cinders, paper, rags, glass articles, metallic substances, etc. It provides a means of simple and durable construction, which will not be clogged up by the service to which it is put and which operates efiiciently to. perform its intended functions. Other features of improvement will be hereinafter set forth.

An embodiment, of the invention is set forth inthe accompanying drawing, whereshows a longitudinal vertical section (with parts in elevation) and Figs. 2, 3, and 4, transverse sections on the lines 22, 3.-3, and 4-4 respectively of Fig. 1.

In said drawings, A, B and C, designate a series of rotatable screens, adapted to empty one into another, and D a chute, preferably rectangular in cross section, into which the material passes after being acted upon by the screens.

The screens may able manner and suitable means are provided for rotating them. As here shown, each of the screens is provided with a circular rack E, running in grooved rollers F, and meshing with a gear G, connected through bevel ears H to the shaft of an electric motor The screens are preferably so proportioned that the delivery end of one fits within the receiving end of another, as for instance the delivery end of the screen A fits within the receiving end of the screen B, thereby avoiding the formation of an obstruction by the ends of the screen. The screens are also Figure 1 preferably adapted to rotate at different ighty-fourth street,

a means especially be. mounted in any suit-- relative s code, and also to have the relative spee s varied. The screens will,ordinarily rotate at different relative speeds, owing to. the fact that they areof different diameters, and being rotated by independent electric motors, variation in the relative speeds of rotation may be produced by increasing or diminishing the speed of opera.

tion, of one or more of the motors.- The first screen where the smallest particles are sifted out, should preferably receive the greatest speed of rotation; therefore it may be retated at the fastest speed,.and the succeeding screens at successively lesser speeds.

A casing J is preferab y arranged around the hoppers to confine the cloudsof dust and fine particles produced by the screening operation. The dust is preferably removed from the casing andfor this urposesuitable means may be rovide As here shown, an'electrically riven fan 0 is provided, which reduces a current of air in a conduit 72, which acts by inspiration, through orifices g, r. and s, over each of the screens and branch conduits t and u, to draw the dust-laden air from the casing J into the conduit 72 and carry it away, as to a bin or receptacle U hereinafter referred to. a

The screens A, B and G and the chute D are preferably mounted upon a frame K arranged at a suitable incline so that the material may move through the-apparatus un der the influence of gravity. The frame K is furthermore preferably mounted at one end upon a pivoted bearing L and supported at its other end uponlifting means, such as a jack M, by which the inclination of the parts may be adjusted to the frictional resistance of the material operated on, which I screens. Material passing from the hopper into the, screen A is agitated and the screen being provided with small perforations, is y sifted and has such particles as partial ashes and other fine particles removed therefrom. From the screen A the material passes to the screen B where it is again agltated and further sifted. The screen B is provided with larger perforations than the vary from various causes, as for inwho sorted is dumped, and which delivers theisame to the series of screen A, and such parts of the material as small cinders may be removed. From the screen B-the. material may pass to another screen 0 where it undergoes further agitation and sitting. The screen C having larger perforations then the screen B operates to remove the larger particles from the mass. From the screen C the material passes into the chute D, and a swinging door P adapted to be held in adjusted positions by means of a rack and dog Q may be regulatin the passage of t e material through t e chute.

The sifted material which is separated by the several screens, falls into a series of funnels, R, S and T, arranged beneath the screens, andis delivered into separate bins or compartments U, V and W, where it may be collected. As the material passes into the chute D it is referably first acted upon by a vacuum. l hi's vacuum may be, and preferably is, produced by the inspiration of acurrent of air, set in motion in a conduit Y, by an electrically driven fan Z, flowing past an orifice a in the upper part of the chute D (Fig. The efi'ect of this vacuum is to suck up light particles such as paper and rags and deliver them into a compartment or bin 6 into which the conduit Y empties.

From the point where it is acted upon by the vacuum the material passes to a point Where it is acted upon by an electromagnetic separator, c, the action of which is to sepa rate metallic like from the mass. As shown.(see Fig. 4) the electro-magnetic separator 0 preferably comprises a series of electro-magnets 03, 111 front of which moves a belt e, preferably of non-magnetic material, such as an ordinary canvas belt. Pieces of iron attracted by the electro-magnets will be carried to one side by thebelte through an opening f in the side of the chute D and dropped into a conduit 9 after being moved beyond the zone of influence of the magnets. From the conduit g the metallic particles are delivered into a bin or receptacle h.

After passing the electro-magnetic sepav rator such parts of the mass as remain, and consisting mainly of bottles and particles of glass, will be delivered througha conduit 2' at the end of the chute D, into a oin or receptacle is where they are collected, and further separation may be made if desired; Each of thebins or receptacles U, V, W, b, h and 7a is preferably provided with a door, through which the contents may be removed.

rovided for particles such as iron and the m isa door in the chute D throu h which access may be had to the interior t ereof.

Means are provided for antisepticall treating the entire mass of refuse as 1t leaves the hopper. This means may comprise a tank an adapted tocontain a suitable disinfectant t, a pipe y adapted to spray the disinfectant over the refuse as it enters the first screen. A pipe z is also preferably provided through which compressed, air

from a suitable source, may be admitted to the tank to force the disinfectant out through the pipe 3 over the material to be sprayed- While we have illustrated and described one embodiment of the invention, the invention is not to be understood as limited.

thereto, as many changes and modifications may be made therein without departing from the spirit of the invention.

What we claim is 1. In a machine of the class described, the combination of a hollow screen member having inlet and outlet openings, means for feeding material within said member, suction means .fortransversely withdrawing under-sized material through the Walls of said screen, and suction means for simultaneously drawing over-sized material longi tudinally of the screen member through said outlet.

2. In a machine of the class described, the combination of a tubular screen having inlet and outlet openings, material within said screen, a discharge chute arranged at the outlet of the screen and in axial alinement with such screen,

suction means for transversely withdrawing under-sized material throu h the walls of the screen, suction means connected with the discharge chute for simultaneously drawing over-sized material. longitudinally of the screen and through the outlet thereof, and a device located between the outlet of the screen and the last-mentioned suction means for regulating .the flowof material to the chute and to the last-mentioned suction -means.

In testimony whereof, we, DANIEL R. BRYAN and Josnrrr W, BRYAN have signed our names to this specification in the presence of two subscribing witnesses, this 20th day of March 1913.
