SEWAGE SEPARATING AND PURIFYING APPARATUS.

SPEGIFICATION forming part of Letters Patent No. 478,539, dated July 5, 1892. Application tiled October 8, 1891. Serial No. 408,092. (No model.)

To all'whom it may concern:

Be it known that I, WILLIAM F. GooDHUE, of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Sewage Separating and Purifying Apparatus; and I do hereby declare that the following is afull, clear, and exact description of the invention, which will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference markedy thereon, which form a part of this specification.

The main object of my invention is to forcibly and continuously separate by mechanical means the solid from the liquid constituents of sewage and other similar matter.

It consists, essentially, of a cylinder or chamber provided with a reciprocating strainer and with suitable connections and valves, whereby the sewage is fed into said cylinder or chamber and the separated solid and liquid constituents are discharged therefrom into suitable receptacles or conduits.

In the accompanying drawings like letters designate the same parts in the several Iig- Figure 1 is a partial side elevationand vertical axial section of my improved apparatus. Fig. 2 is a vertical cross-section through one of the separating-cylinders, and Fig. 3 is a detail view of one of the sludge-valves with its actuating mechanism.

A A represent two horizont-al cylinders arranged iu line with each other. They 'are provided with screensA B B', fitted and arranged therein in the manner of pistons. They are mounted and fixed upon a pistonrod b, which passes through stuffing-boxes 1n both ends of said cylinders and through an intermediate steam-cylinder C, within which is fitted and mounted upon said piston-rod a piston D. These several cylinders are connected and held iirmly in place by tie-rods c c. The cylinders A A are provided at the upper side of their outer ends with ports a a, which are connected with the supply pipe or conduit VE by branches E E'. These cylinders are also provided on the underside with ports a a. for the discharge of the sludge at the outer ends and at their inner ends with ports a2 a.2 for the discharge of the liquid portion of the sewage from which the sludge has been separated. The ports a2 are connected with a discharge-pipe F by branches F' F', and the ports a open into or are connected with suitable conduits or receptacles.

'lhe branches E E', through which the sewage is fed to the cylindersA A', are provided with valves c e', which are operated by mechanism so arranged as to admit the sewage a1- ternately into said cylinders when the screenpistons B B are at or near the inner ends of their strokes. For this purpose I provide the valve-stems with crank-arms e2 e2, which are connected with slotted'blocks e3 e3, adjustably mounted upon a horizontally-sliding rod e, which is supported in suitable bearings e5. This rod is reciprocated by means of a lever G, fulcru med to a block g, which is adj ustably mounted upon one of the tie-rods c or upon anyothersuitable-support. Thislever is pr vided with longitudinal slots at Vthe ends, by means ofwhich it is pivoted at its lower end to a piu on a collar g', adj ustably vmounted upon the piston-rod b, and at its upper end to a pin on a sleeve adj ustabiy mounted upon the reciprocating valve-rod e4.

. The valve of the engine by which the separater-screens are operated may be actuated byv means of the same lever G. .For this purpose I provide the valve-rod I-I with an adjustable collar h and connect it by a rod h with said lever. To give the proper movement to the valve, the connecting-rod h is pivoted by a crank-pinin a longitudinal slot in said lever' G. To allow for the arc motion of the crankarms e2 in connecting them with thefreciproeating rod e4, I provide the free ends of said crank-arms with crank-pins, which engage with vertical slots formed for their recept-ion in lateral projections on the adjustable collars or blocks e3.

The conduits or passages into which the discharge-ports a. open are provided with transverse slides K K', constituting the sludge-valves. These valves are, normally closed by means of springs k and are opened against the opposing force of said springs by' means of hooks ll,pivoted to depending arms L L, mounted upon the projecting ends of the piston-rod b, and by blocks 7c' k on the stems k2 of said sludge-valves, the hooks Z being aras the hooks l are released from position in which they are shown in the drawv tions thereof to pass ings, the valve e is closed and the valve e' is opened, thereby admitting sewage to the outer end of cylinder A through the port a. AIn this position of the separating-screens the sludge-valve K is closed, while the valve K at the opposite end of the apparatus is opened. Now as the piston D is reversed and moves the screens B B tothe right the valve e will be opened and the valve e will be closed. The screen b', advancing against the sewage contained in cylinder A', permits the liquid porthrough it into the inner end of the cylinder, whence it-escapes through the port a and branch E into the discharge pipe or conduit F, the solid constituents of the sewage being carried tothe outer end of the cylinder, and the greater part of the liquid expressed therefrom is as the screen B nears the end of its stroke discharged through the port a' by the opening of the sludge-valve in the manner hereinbefore described. While the latter operation is going on in the cylinder A the cylinder sewage, and thus the operation goes on continuously, first one and .then the other cylinder being filled and the sludge being separated and discharged alternately in opposite ends of the apparatus.

Various changes may be made in the details of my apparatus within the scope of my invention. Where apparatus of small capacity is sucient, a single-acting separator, like or similar to one end of the apparatus hereinbefore shown and described, may be employed.

While I have shown and described my apparatus as specially designed for operating upon sewage, I do not wish to be understood as limiting myself thereby `to such particular use, inasmuch as the apparatus may be applied with advantage to the separation of the solid and liquid portions of a'variety of matter other than sewage.

I claim- 1.
