SINCLAIR STUART, OF PLAINFIELD, NEW JERSEY.

SEPA RATO R.

To all whom t may concern:

Be it known that l, SINCLAIR STUART, of Plainfield, in the county of Union and State of New Jersey, have invented a new and useful Improvement in Separators for Steam-Pipes, of which the following is a specification.

My invention relates to a separator which may be inserted in aline of pipe for live or exhaust steam, and which will separate from the steam the water, and in case of exhauststeam also the oil, which is always carried from the cylinder of an engine, steam-pump, or similar machine, and thus prevent the boiler and the condenser, if one be used, being injured by the deposit of oil and grease therein. When such a device is applied to an exhaustpipc for supplying exhaust-steam to a system of heating-radiators, it prevents oil and grease from being carried 4to and de' posited in the radiators, and thereby prevents foul odors which are frequently produced where such deposit occurs.

In my Letters Patent No. 362,191, dated May 8, 1887, I have shown a device for 'the purpose, consisting of a chamber wherein are arranged catch-plates or abutments against which the steam impinges; but I have now discovered that the desired result may be accomplished by constructing the device so as to afford free opportunity for the expansion of the steam and for the escape from the steam-pipe of the water and oil which will be caused, to deposit by the reduced velocity consequent on such expansion.

The invention will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure l is an elevation, partly in section, of my device; and Fig. 2 is a transverse section thereof on the lplane of the dotted liner x, Fig. l.

Similar letters of reference designate corresponding parts in both figures.

A designates the steam or exhaust pipe in which my device is applied. The sections of this pipe at opposite sides of the separator are connected with a pipe-section, B, form ing a part of the extractor, and which is usually of larger diameter than the pipe A, so that as the steam reaches theY pi pe'section B it will expand and will have its velocity correspondingly reduced. The separator comparent No.3e3'74, dated May 29, lese.

`Serial No. 258.458, (No model.)

prisesa chamber, B', which surrounds the pipe section B, and it has at its lower portion a well, B2, which is in openvcommunication with the chamber B', and forms, in fact, a part thereof, both being formed in asingle casting. At the bottom of the well B2 is an outlet-pipe, b, provided with a valve, b', and through which the water and oil may be withdrawn from time to time. The well B2 may also have applied to it agage-glass, b, for indicating the level of oil and water within it.

The pipe-section or passage B is perforated throughout its length, which is covered by the chamber B', or has numerous openings a formed therein, through which water and oil, and also steam, pass into the chamber B. As here represented, the portion b of said pipesection B which is outside the chamber B', and therefore imperforate, is of gradually-increasing diameter, or inwardlyiiaring in the direction in which steam enters, and as the steam passesinto and through the pipe section or passage B its velocity becomes reduced, owing to its expansion, and the particles of water and oil deposit, owing to their specific gravity, and find their way through the openings a into the chamber B' and thence to the well B2. So, also, any steam which passes through the openings a has its current broken up and loses its velocity and allows the water and oil held in suspension to deposit in the chamber B'.

When the separator is applied in an exhaust-pipe which communicates with a condenser, and wherein a vacuum is to be maintained, the outlet b may have applied to it a dischargingchamber, also having a valved outlet, as shown in my aforesaid patent, and then the well B2 may be discharged without interfering with and notwithstanding the vacuum in the chamber B'.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The separator herein described, consisting of a steampipe section or passage which is perforated or formed with lateral openings, and with the ends of which are connected the steam-pipe sections, and a chamber surrounding the perforated pipesection or passage, and which is constructed to forni :a well for IOO receivingwaterund oii,substantia1ly asherein receiving the water and oil, and provided set forth. with an outlet-pipe therefor, substantially as Io 2. The combination, with the pipe-sections herein set forth. A, of the separator, comprising the pipe-seo- SINCLAIR STUART 5 tion or passage B, larger in diameter than the sections A, and having lateral perforations or Witnesses:

openings, the chamber B', surrounding the C. HALL, pipe section or passage B, and the weil B2, for FREDK. HAYNES.
