GEORGE ILSLEY ROBERTS, OF NEW ROCHELLE, NEW YORK.

EXHAUST-HEAD.

SPECIFICATION forming part Of Letters Patent NO. 731,816, dated June 23, 1903.

Application filed April 17 1903. Serial No- 153,029. (No model.) I

To all whom it may concern.-

Be it known that I, GEORGE ILSLEY ROB- ERTS, a citizen of the United States, residing in New Rochelle, Westchester county, and

reliably efficient in its operation of condensing the steam and the collection and return of the Water of condensation.

My improvements consist in the special construction, arrangement, and combination of the several parts, portions, or details comprising the apparatus, as hereinafter shown, described, and claimed.

Referring to the drawings, Figure l represents a sectional view of an apparatus embodying my improvements. Fig. 2 represents a cross-section of the apparatus on line w w of Fig. 1 and showing plan views of the diaphragm-partitions. Fig. 3 represents a cross-section of the apparatus on line y 3 of Fig. 1', showing a plan view of the supporting exhaust connection.

Similar letters of reference designate like parts, portions, or details in all the figures.

A designates the connection to exhauststeam pipe, made, preferably, of cast-iron for B designates the main shell or casing, and C a closed head through which the air-tubes D pass. These tubes are inserted and adapted for cooling and condensing the steam or fluid matter passing around about or coming in contact therewith by reason of a circulation of cold air from without passing through said tubes.

E and E designate diaphragm-partitions, preferably conical in shape, located within the shell, as shown, to control the movement of the treated steam or fluid matter for muffling and condensation purposes. F designates a plurality of outlets for the uncondensed steam. They are located in the upper portion of shell B.

G designates a local drain for disposing of all liquid settling upon the diaphragm-partitions E when closely attached to thew'alls of shell or casing B. Any liquid settling into the inner diaphragm-partition E overflows at the periphery of said diaphragm-partition and drops into the annular cup portion or compartment a of the exhaust connection A, whence it exits through drain H for delivery as desired.

In the operation of the device, as shown, the steam or any exhaust fluid enters through the exhaust connection A, is met by and impinges upon the inner or central diaphragm guide-partition E and against the cooling-surfaces of the air-tubes D. Passing through the several spaces between the air-tubes, the steam next impinges upon the outer shellB, rises and impinges upon the outer diaphragm guide-partition E, and again passes through the spaces between the air-tubes to the center of the shellB, and again, fora third time, through the air-tube spaces to the upper portion of shell B, impinging upon and reacting from the top head 0, to pass outthrough one or more side outlets F to the atmosphere. All water or fluid condensation received by the outer diaphragm-partition E passes down through drain G and drops to the annular space a of connection A. The water orfluid condensation received by the inner or central diaphragm-partition E overflows its edges and drops into the said annular space a, for discharge through outlet H. Only two diaphragm-partitions, an inner or central oneE and an outer one E, are shown in Fig. 1. These may, however, be duplicated or multiplied, according to the length of shell 01' the demands of condensation. The annular spaces a are formed by and between an upward or vertical extension of the exhaust passage or connection and a surrounding cupshaped attachment, to which the main casing or shell B is secured or which may be extended or carried up to form said shell.

To provide for any expansion and contraction in the apparatus, the air-tubes D are preferably expanded into the metal of the exhaust-inlet connection'and are left free to move through holes in the upper head 0.

I do not confine myself to the exact detail and construction shown and described, but

claim the right to make any slight changes and alterations compatible with the spirit and scope of the invention.

What I claim as new, and desire to secure by Letters Patent, is

1. In an exhaust-head, in combination With 1 the exhaust connection and attached shell, a

plurality of cooling air-tubes located Within said shell, a closed head to said shell, and one or more outlet-openings in the vertical siding of said shell, substantially as and for the purposes set forth.

2. In combination with the inclosing shell of an exhaust-head, a plurality of contained air-tubes, one or more contained diaphragm I5 guide-partitions, a closed head to said shell and one or more outlet-openings in the vertical siding of said shell, substantially as and for the purposes set forth.

GEORGE ILSLEY ROBERTS.
