ARTHUR J. FILKINS, OF RIVERSIDE, ILLINOIS F'ICE.

EXHAUST HEAD F OR EXHAUST-STEAM PIPES.

Application filed June 10, 1922. Serial No. 567,477.

To all whom it may concern:

Be it known that I, ARTHUR J. FILKINS, a citizen of the United States, residing at Riverside, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Exhaust Heads for Exhaust-Steam Pipes, of which the following is a specification.

As is well known, exhaust steam pipes for exhausting the-steam from engines and the like, when installed in cities or other closely built localities, are commonly carried upwardly to a point above the roof of the building in which the steam engine is located, and

r from this point the exhaust steam is expelled with considerable force into the atmosphere in a series of sharp staccato puffs in rapid succession. This results in a spray of minute particles or drops of water accompanied frequently with small globules of lubricant, as oil and the like, being discharged into the atmosphere with the steam, which has the objection of wetting and soiling anything'within its path of descent to the street level.

This discharge of steam from steam exhaust pipes has proven such a nuisance that cities have found it necessary to pass ordinances prohibiting the discharge of exhaust steam pipes into the atmosphere, unless such pipes are equipped with a suitable trap or exhaust head for muflling and controlling the discharge therefrom.

The primary object of. the inventionis to.

provide an improved exhaust head which will so control the exhaust steam as to check the force and mufiie or deaden thesound with which the steamis expelled into the atmos phere and cause the steam to rise from the exhaust head in a gradual manner and without force.

A further object of the invention is to provide an exhaust head that will expedite condensation and collect all condensation of steam therewithin and direct the water re-. sulting therefrom to a roof gutter, sewer or other point of discharge.

Other objects of the invention will appear from the following description of the preferred form thereof, shown also in the drawing forming a part of the specification, the features of novelty being set forth in the appended claims.

In the said drawing, Fig. 1 is an elevation view, partly in section, of the improved exr Reference character 10 indicates the outer i casing of the improved exhaust head andhas the nterlorly screw threaded portion 11 extending downwardly from the bottom thereof for receiving exhaust steam pipe 12 in screw threaded engagement therewith, as at 13. gcrew threaded portion 11 extends upwardly lnto the casing 10 forming an annular wall 14 around the central internally screw threaded opening 15 in'the bottom of casing 10, thus forming a gutter or drainway 16,'which communicates withdrain pipe 17, which has screw threaded engagement with the screw threaded opening 18 adjacent the drainway 16. Drain pipe 17 may communicate with a roof gutter, sewer or any other means for the disposal of waste water and is forth'e purpose of draining water which is collected in utter 16 from the condensation of steam wit in the exhaust head. The wall of the outer casing 10 is thickened at its upper end, as at 19, and isrecessed on its inner periphery forming a seat 20 for the reception therein of radial arms 21 on the circularcup like bafile 22. Baflle 22 is suspended within and concentrically with outer casing 10 with its wall spaced from the wall of the outer casing to provide a passageway for the exhaust steam upwardly to cap23. Cap 23 is formed With an inwardly extending wall which is inclinedtowardthe center, first upwardly as at 2 1, and then downwardly, as at 25, forming an apex 26. The downwardly inclined wall 25 terminates in a downwardly extending portion or throat 27 which extends into and concentrically with the vertical wall of baffle 22. The cap 23 with its, downward ly extending throat 27 thus forms a second and abrupt battle in the path of the exhaust steam which practically completely checks the force with which the steam is expelled from the outlet of the steam head. The steam is thus caused to rise from the steam head in an approximately uniform flow and with greatly reduced force. Baffle 22 has a concavo-convex bottom 28 and is provided with an outlet 29 for water collecting in the baflie from the condensation of steam which outlet discharges into the outer casing 10, and from which the water thus collected is carried from the outer casing by pipe 17 to a point of discharge.

Casing 10 has radially'extendingears 30, preferably three in numbr, which ears are bored, the bores being adapted to register with similar bores through. ears 31 carried by cap 23 for the reception therethrough of bolts 82 which are adapted to receive thereon screw threaded nuts 33 for securing the assembled parts of the exhaust head in proper relation.

It will be appreciated from the foregoing disclosure that exhauststeam expelled into the exhaust steam pipe from the cylinder of an engine will first come into contact with the bottoin28 of baffle 22 and be given a downward and outward course, and will pass thence upwardly between the outer wall of the battle cup and the wall of casing 10 into contact with the top cap 23, being thence deflected downwardly aroundthe outer periphery of throat piece 27 and thence upwardly and outwardly through the discharge opening therein, thus greatly reducing the force and rapidity with which the exhaust steam leaves the cylinder head. At the same time particles of oil or condensed steam will be entrapped and drained through the drain pipe 17.

In order that the invention might be understood I have shown the details of the embodiment of the invention that has been found most successful and that is preferred by me. but it is not desired to be limited to the details of the invention except as defined in-the claims, since it will be apparent that persons skilled in the art may resort to various modifications without departing from the purpose and spirit of my invention.
