' Lon'gIsland, and State of New Yorlghave in vented' certain new' anduseful Improve;- ments in DiffusionfOutlets for Conduits,- of which the followingis av specification.

My invention relates to diitfusion outlets forco11(:luits, and particularly to'an outlet cover or guard, which not only lessens jdan gerof stoppage, but also aids; 1n effecting discharge from the conduit. The invention is particularly applicable" to submerged sewer pipe outlets.

In the accompanyingdrawings 1. is a side elevation of a di-iiusion block inwhichmy invention is enibodied in one form;

Fig. 2 is a broken" plan thereof;

It is a. frequent practice for municipalities to pipe theirv sewage of water, such as av river, ti'dal basin, etc.,

and to discharge the sewage into the latter through ports formed at intervals in the length of the sewer pipe. Often object's sus pended in the water of submergence' become lodged in the outlet openings of the conduit and block discharge therefrom. It requires constant inspection of the line to keep the openings free from this trouble; The object of the present invention is to provide a diffusion block adapt-ed to'be arranged at such 7 ports and serving not only to prevent stop page thereof, but also to deflect the flow of the water of submergence past the opening so as to assist in the discharge of the sewage from the pipe. While I have referred to submerged sewers as the type of construction to which the invention is particularly applisection on the line 14- 14,

to a neighboring body cable, it will be understood of coursethat' the construction may 'be used inrnany other in stallations to advantage-,and 1010 not liinit its application, therefore, to sewer pipe. 4

V Referring to the" constructions shown in Figs; 1 to 3,1the conduitQO, through: which the liquid to" be discharged flo wsp is indi cated as niadelrom concrete,'and has a pe ripheral port 21 formed therein through: which the liquid escapes In order' to prevent,-' as 'far as possible, the retention of any" solids at the mouth of the port, its mazrgin isround'ed, a's at' 22', to affordasmooth pas sageway. As" will be noted troni F-igl2ythe" port is here shownaslsubstantially rectan gular in plan. Covering this opening' is a diiiiusion bloclz 23 which, wherefithe conduit is of concrete, may similarly bemolded from concreteaand its 'concavv'e seatfi may beset in grout on the pipe 20, to* assist in holding iti-n position. I have provided also a pair" of steelbands-25, which pa'ss beneath the conduit and over thebloclnwliere they-are drawn tightby bolts QG'en'ga-ging the angle iron ends 527. The block thus forms an arch, which overlies the port 21 and affords lateral discharge openings" 28' at right angles to the axis oi" the pipe." Cast integral with the block at its opposite ends, in'the direc tionof the length'of the pipe; are deflecting plows or

vanes

29 and 30. Where thepipe is submerged in water wh-i'ch'flows in oppo"- site directions, as in a tidal basin, the vanes 29* and 30 deflect the current and divert it outward so thatat' the discharge ports the fiow'past the outlet is at an angle to the axis of the pipe". This not only tends to keep any suspended matter in the water of submergence awayfrorn the aperture, but also exerts a certainsuction effort which aids in'discharging. the contents of the conduit.

WVhere the conduit is located in a stream, where the direction of flowis always in-one direction, the diffusion block may have but a single deflecting vane, pointed" rip-stream, as illustrated in- Figs. 4, 5'and 6: Inthis case I have shown the'discharg'e 'portin'the pipe as: circular, and the diiiusion block is preferably located with its upstream end wall adjacent the up-stream side of the discharge port. The margins of discharge port '31 are outwardly flared to prevent clogging.

diffusion block has its discharge opening arranged at the down stream end of the block in the direction of the flow of the current. The discharge port 33 in the conduit is flared at its outer margin only, to assist in maintaining the aperture clear.

In Figs. 10, 11 and 12 the conduit is provided with a pair of discharge openings 34: and 35, which open to a corresponding pair of

channels

36 and 37 diverging from the axial line of the pipe and opening to the sides of the diffusion block. Obviously, the same effect is obtained in this construction as in that first described by reason of the current-deflecting vane 29 at the up-stream end of the diffusion block.

In all of the constructions, I have indicated small holes 38 in the blocks to facilitate their manipulation during manufacture and adjustment in position on the conduit.

Various other modifications in construction and arrangement of apertures and discharge channels will readily occur to those skilled in the art which obtain substantially similar results, without departing from what I claim as my invention.

I claim- 1. For use with a submerged conduit having a discharge port in its crown, a diffusion block adapted to be arranged over the port and shaped to deflect the water of submergence into an outwardly directed current, and having a lateral discharge aperture communicating with the conduit port and leading thedischarge therefrom toward said outwardly directed current in I the water of submergence.

2. For use with a submerged conduit having a discharge port, a diffusion block adapted to be arranged over the port and having a lateral discharge aperture coinmunicating with said port, said diffusion block being independent of the conduit and having associated means embracing the conduit for securing the same in position over the discharge port in the conduit.

'3. For use with a submerged conduit having a discharge port, a diffusion block adapted to be arranged over the port and having a lateral discharge aperture communicating with said port, together with projecting end vane means for deflecting the liquid of submergence away from the outlet of the diffusion block.

'41; For use with a submerged conduit having a peripheral port, a diffusion block having an arcuate seat adapted to rest on the conduit, an outwardly flared lateral dis-.

charge outlet from the diffusion block, and

a passage establishing communication between said outlet port in the conduit.

5. A difl'usion block of the type described having a passage adapted to be placed in register with a peripheral port in a conduit 011 which the block is adapted to be seated, a lateral discharge outlet to which said passage opens, and a deflecting nose at an end of the block and extending in the direction of the pipe length.

6. The combination with a conduit submerged in a flowing body of water, and having a peripheral port, of a diflusion block seated on said conduit at said port and having a lateral outlet, together with a deflecting nose for said diffusion block, said nose being pointed up-stream, and serving to cause the water of submergence to be laterally deflected at the block for the purpose specified.

7. For use with a submerged conduit having' a discharge port, a diffusion block adapted to be arranged over the port and having a lateral discharge aperture communicating with said port and opening to the water of submergence at a point above the crown of the pipe.

8. For use with a submerged conduit having a discharge port, a diffusion block adapted to be arranged over the port and having a lateral discharge aperture communicating with said port and extending in a direction substantially parallel to the transverse horizontal axis of the pipe.

9. For use with a submerged conduit having a discharge port, a diffusion block adapted to be arranged over the port and having a lateral discharge aperture communicating with said port, said block being shaped to deflect the flow of the water of submergence past the port away from said aperture but in the general direction of the flow of said water of submergence to pro duce a suction effort aiding the discharge from said aperture.

10. For use with a submerged conduit having a discharge port, a diffusion block adapted to be arranged over the port and having an outwardly flared lateral discharge aperture communicating with said port, said diffusion block having a V-shaped plow end serving to deflect the flow of the water, of submergence past said aperture in a direction to exert a suction effort at the aperture for the purpose specificed.

In testimony whereof I have signed my name to this specification.
