UNITED STATES WILLIAM ZELLNER, OF PATERSON, NEW JERSEY, ASSIGNOR TO THE GON- SOLIDATED SAFETY VALVE COMPANY, OF BOSTON,-MASSAGHUSETTS.

NOlSE-QUlETING STEAM-NOZZLE.

SPECIFICATION forming part of Letters Patent No. 227,341, dated May 4, 1880.

Application filed October 14, 1879.

To all whom it may concern 1 Be it known that I, WILLIAM ZELLNER, of Paterson, in the county of Passaic and State of New Jersey, have invented a new and useful Improvementin Noise-Quietin g Steam-Nozzles; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, forming a part of this specification,

in which- Figurel represents an elevation, and Fig. 2 a central vertical section, of a device embodying my invention.

The object of this invention is to subdue the r 5 noise of escaping steam.

The invention consists in constructing an escapepipe nozzle or chamber, through which the steam passes in its passage-to the atmosphere, with internal deflecting plates or parti 2o tions that form a circuitous passage therethrough and subdivide the escaping steam by interposed wire-gauze, perforated plates, or other porous material.

In order that others may understand and use my invention, 1 will first proceed to describe the construction and operation of a device embodying the same, and subsequently to define in the claims the novel features thereof.

In the drawings, A represents a hollow cyl- 0 inder 9r case, provided with fixed heads a at, having central openings 1) b for the inlet and exit of the steam. v a

The head a is provided with a projecting horizontal flange, 0, to be connected to a cor- 3 5 responding flange upon an escape or exhaust pipe of the boiler, the central opening b forming the inlet-passage to -the instrument.

The opening I; is surrounded by an inwardlyprojecting cone-shaped'nozzle, (1, its apex form in g a contracted passage for the steam.

0 represents a hemispherical plate of somewhat larger diameter than the opening at the inner end of the nozzle-d, and located directly above the same, the base of the hemispherical 5 plate 0 being in line with the inner end of the sides of the case A, having a passage, 12, for the steam that is directed thereto by the hemispherical plate 6. This plate 6 is also provided with a central opening, h, through which a portion of the steam is allowed to pass.

The opening it is covered by a cap, 0', corresponding in shape to the plate 0, and afflxed thereto by stud-bolts k k, to form an annular passage over and around the top'of the plate 0.

mm are deflecting-plates, arranged horizontally, as shown, the plate m having a central opening for the passage of the steam, and the plateau made solid and shortened to leave an annular passage, a, between it and the case A, similar to the arrangement of the flange 9 upon the hemispherical plate e.

0 represents a series of'wire-gauze partitions, arranged vertically between the deflectingplates m m and flange g, and with intermediate spaces, as shown. These partitions areinterposed to fill the circuitous passage formed bythe deflecting-plates for the purpose of subdividing the steam. Any number of suchpartitions may be introduced to make up the respective series, and any suitable material that will permit the passage of the steam in a divided state may be substituted therefor.

The exit-opening b is fitted with a short pipe, 12, extending through the head a, projecting outward and provided with a flared end, and also projecting within the case or cylinder, as shown. The inwardly-projecting portion of this pipe may also contain a series of perforations, i, as shown, to continue-the subdividing process up to the point of the final exit of the steam to the atmosphere.

S represents a perforated plate, which serves to cover a portion of the annular space surrounding the nozzle d, and within which water producedby condensation of the steam may lodgeand be withdrawn through the pipe 10.

The operation of my invention will be readily appreciated by an inspection of the relative arrangement of the parts and composition of I the substance interposed within the circuitous nozzle (l and forming an annular passage, f,to the interior of the case or cylinder A, as indicated by the arrows, Fig. 2. p The hemispherical plate 0 is alsop'rovided with a surrounding 5o horizontal flange, 9, that extends nearly to the passages for subdividing the escaping steam without further explanation, the efl'ect of such a result being authenticated by variously-contriveddevices involving the same principle.

Therefore,

IOG

Having thus fully described my invention, What I claim, and desire to secure by Letters Patent,'is-

l, A pipe, nozzle, or chamber for the passage of escaping steam, provided with internal pro.- ject-ing plates, forming a circuitous passage therethrougl and having one or more interposed Vertical partitions, composed of wiregauze, perforated plates, or other porous mate rial, whereby the escaping steam is separated or divided, for the purpose specified.

2. A pipe, nozzle, or chamber for the passage of escaping steam, provided with an inwardly-projecting nozzle, (1, forming the inletpassage, a hemispherical deflecting-plate, 0, having a projecting flange, g, one or more horizontal deflecting-plates, m m, forming a circuitous passage therethrough, and one or more series of interposed partitions, composed of wire-gauze or analogous material, whereby the 20 escaping steam is subdivided, for the purpose specified.

3. The hemispherical plate e,. having the central aperture h, in combination with the cap 0, whereby a passage is formed for a di 25 vided portion of the steam, for thepurpose specified. I I

,4. The exit-opening b, fitted with a pipe, 1), projecting within and beyond the head a, and

'withor without the perforations r, substano tially as set forth.

WILLIAM ZELLNER.
