STEAM-VAPOR SPRAY.

Specification of Letters Patent.

Application filed Gctober 30, 1912.

Patented July 28, 1914-. Serial No. 728,602.

To all whom it may concern llc it known that I, WILLIAM H. GO'UGH, a citizen of the United States of America and a resident of Valley Falls, in the State of Rhode Island,havc invented a new and useful Improvement in Steam-Vapor Sprays, of which the following is a specification,

This invention relates to those sprayers or lnimidifiers known as steam vapor sprays which are supplied with steam only. An 0bjecticn to these devices as employed in the weaving' rooms of cotton mills is the occasional discharge of drops of the water of condensation with the vapor spray. Some of them are constructed with special reference to converting the water of condensation into spray, and I know of none in which the Occasional discharge of drops of "ater is ctli'ectively prevented.

The leading object of the present invention is to insure the absence of all water of condensation from the spray,

Another object is to facilitate discharging the spray from each device through a pluralitv of horizontal nozzles with reference especially to the location of the device in an alley between looms and the discharge of the spray l'iorizontally on both sides of thc alley above the looms on its respective sides so as to reduce the number of instalments required for a given area,

Other objects will be set forth in the general description which follows.

A sheet of drawings accompanies thls specification as part thereof.

Figure 1 is an elevation partly in section; Fig. 2 represents a longitudinal section through one of the nozzles; Fig. 3 is an end view of a nozzle.

Like reference characters refer to like carts in all the figures. In the ii'nproved apparatus, a steam pipe (1 leads horizontally into a vertically elongated hollow member 7), conveniently round in crosssection and of any required length, forming a vertically extended expansion chamber, 0, free from partitions, in which the steam is reduced to water vapor of suitable quality. This chamber need not be more than two inches in diameter. The delivery end a of the steam pipe within the chamber 0, is extended downward from a point above mid-height at which the pipe enters, so as to facilitate and insure the escape of water of condensation downward. therefrom From a central terminal collar at the domed and otherwise closed upper end of the chamber a connecting pipe (I extends to the required height, and is coupled by a T c, to oppositely projecting horizontal pipes f and g, each terminating in a suitable vapor-spray nozzle 72, one of which is reprcsentcd in detail by Figs. 2 and 3. The aperture 2? in each nozzle is round and axial, and may be one-sixteenth of an inch in diametcr being in all cases much smaller than the inlct chamber of the nozzle. See Fig. 2.

A drip pipe extends downward from the lower end of the chamber 6, within which *atcr of condensation nut accuinulate as represented in Fig. 1, but never so as to be discharged with the vapor-spray. Should the discharge of this water through the drip pipe j be neglected, its contact with the steam inlet a will give audible notice of that fact.

Simple globe valves, 1, 2, 3, 4, provide respectively (1) for controlling the How of steam through the steam pipe (2, (2 and 3) for regulating the discharge of vapor-Spray -from the several nozzles, and (4;) for regulating the discharge of the water of condensation tl'irough the drip pipe j. All the globe valves 1, 2, 3, 4, are readily located so as to be easily accessible; and they are the only parts of the apparatus requiring repairs; which consist in replacing one or more of the valve disks, at a cost of a few cents.

The pair of horizontal pipes f and g, each about six inches long, are designed to 'etl'ectively locate the vapor-spiny nozzles ii on opposite sides of a weaving-room alley, so as to discharge the spray from one and the same apparatus over two looms.

One or more additional horizontal pipes may obviously be added; or vapor-spray nozzles of a different pattern, or having apertures of other forms, may be substituted for those shown; and other like 1nodifications will suggest themselves to those skilled in the art.

Any apparatus in which water is sprayed however foreign to the present invention. It will be seen that in the hereinbefore described apparatus the only discharge is of steam vapor spray from which water of condensation has been separated (1) by the downwardly directed steam inlet a (2) by the top of the expansion chamber 0, (3) by the T e or its equivalent at the top of the vertical pipe (Z and (4:) by the inlet chambers of the vapor nozzles h, these chambers being large compared with the axial discharge apertures i as shown in Fig. 2.

Having thus described said improvement, I claim as my invention, and desire to patent under this specification:

1. A steam-vapor-spray apparatus conr prising a steam-supply pipe having a clownwardly extended delivery end, a vertically elongated hollow member forming a vertically extended expansion chamber into which said pipe extends horizontally, said chamber member having a central terminal collar at its domed and otherwise closed upper end, a pipe extending vertically upward from said collar, a coupling at the upper end of this pipe, a plurality of horizontal pipes in communication with said chamber through said coupling and said vertically extending pipe, vapor-spray noz zles having drip-preventing chambers at the extremities of said horizontal pipes, and

a means for draining said expansion chamber.

2. In a vapor-spray apparatus supplied with steam only, the combination with a horizontal steam pipe, of a vertically elongated hollow member forming a vertically extended expansion chamber into which said steam pipe extends above mid-height of the chamber, and within which said pipe is eX- tended downward, said chamber member having a central terminal collar at its domed and otherwise closed upper end, a pipe extending vertically upward from said collar,

and means for regulating the flow through each of said horizontal pipes and through said drip pipe, substantially as hereinbefore specified,

WM. H. GOUGH.
