Application filed April 12, 1920. Serial No. 378,295.

To all whom it may concern:

Be it known that 1, CHARLES E. A'rKINsoN,

a citizen of the United States, residing at' South Bend, in the county of St. Joseph and State of Indiana, have invented certain new specification.

The invention relates to a water trap for air-brake systems, and is adapted for installation in the air line for the purpose of separating water of condensation'from the air stream.

The object of the invention resides in the provision of means for separating water of condensation precipitated within the pipes of an air-brake system from the moisture in the air, due to the heat of the pressure pump induced by friction-and high compression, sweating of the pipes, and from other causes,

at points in the line which will render the system inoperative by the freezing thereof in cold weather. A further object resides in the provision of means for the purpose stated, which will be simple and cheap of structure, and which will be highly eflicient for the purposes thereof;

With the above and other objects in view, the invention in its preferred details of structure will be described in the following specification, reference being had particularly to the accompanyin drawing, which illustrates the device part y in section and partly in elevation.

Referring now more particularly to the said drawing, the reference numeral 1 designates a cylindrical casing formed preferably with an integral head end 2, provided with a centrally threaded aperture 3, and with a removable bottom end 4, secured, as

by means of bolts 5, to the annular flange 6 of the cylinder. Integrally formed with the cylinder are oppositely disposed perforate lugs or cars 7 adapted to receive means for mounting or supporting the casing in the installation thereof.

Preferably formed integral with the easing and disposed at a point in close proximity with the upper end of the casing, is an inwardly and upwardly directed spout 8, adapted for connection with an inlet pipe 9, leading, for example, from the air pressure pump of an airbrake system. Threaded at one end into the aperture 3 of the head of the casing, and terminating short of the lower end thereof, is an outlet pipe 10, leading, for example, through a pipe connection 11, with the air reservoir of the system. Enclrcllng the outlet pipe 10 and extending the length of the casing is a spiral baffle member l2, slightly spaced at its outer ed e from the casing, and toward the under side of- WhlCll the inlet spout 8 is directed. Threaded into the bottom end of the casing 1s a pet-cock 13 for draining the accumulated water from the casing.

In operation, the inrushing air stream under force of the pressure pump is directed upwardly of the casing and projected against the under side of the spiral baiiie, so that any partlcles of water carried by the air stream will be deposited thereon and flow downwardly thereon to the bottom of the casing. It Wlll be apparent that the water 'particles' or moisture is deposited on the and thus prevent the lodgment of the water under side of the spiral balfie, and that it will thus flow to the bottom of the casing on the under side of the baflle throughout the length thereof, thus fully protecting the same in its flow from the down rushing air, and measurably preventing the air stream from picking up again the particles of water. Furthermore,the upwardly directed inlet will causethe incoming air to meet down flowing air, and by the aid of the spiral baffle, cause the incoming air stream to be thoroughly broken up and diffused, so that particles of water and moisture carried thereby may more easily precipitate by the decreased density of the air.

While the foregoing improvement is particularly described and adapted for use in connection with air-brake systems, it is obvious that the same may be used in other connections where the same results are desired, hence I do not limit myself to the use thereof in any particular connection. Also I do not limit myself to the'precise structure shown and described, as it is obvious that modifications thereofmay be made without departing from the spirit of the invention as defined by the claims.

Having thus described my invention, what is claimed is:

1. A water trap for air conducting lines comprising a casing, an outlet pipe extending downwardly into and terminating short at the bottom of the casing, a spiral baflle member encircling said outlet pipe from a point adjacent the upper end of the casing to its lower end, the lower end of said spiral bafiie member extending below the lower end of the outlet pipe, thereby formin means for conducting the water downwar 1y to a point below the lower end of the outlet pipe and an inlet pipe connected to the casing adjacent its upper end. 7 i

- 2. A water trap for air conducting lines comprising a vertically disposed casing, an outlet pipe extending downwardly into and terminating short of the bottom of the casl0 casing, and an inlet pipe carried by said 1?;

casing adjacent its upper end.

In testimony whereof I aflix my si CHARLES E. ATKINSON.

ature.
