EXHAUST-HEAD.

Specification of Letters Patent. Patented Mar. 24, 1914:.

Application filed July 19, 19-11. Serial No. 639,415.

To all whom it may concern Be it known that we, CHARLES B. KLINGE- MANN and WVALrnR Gr. Ruocnns, of South l/Veymouth, county of Norfolk, and State of Massachusetts, and of Reading, in the county of Middlesex and State of Massachusetts, respectively, have invented certain new and useful Improvements in Exhaust- Heads, of which the following is a specification.

This invention relates to a device adapted to be fastened upon the pipe which conducts exhaust steam from steamengines, and other machinery using steam for motive power, to the outer air.

In many mechanical power installations the exhaust steam is discharged directly into the outer air by a pipe passing through the wall or roof of the building containing the power plant, instead ofbeing condensed, and it is upon such an exhaust pipe that the device in which this invention is embodied is intended to be attached for the purpose of removing water of condensation and 011 from the steam before discharge of the steam.

The object of the invention is to provide a device of this kind, or exhaust head, so constructed that it may be attached to the end of an exhaust pipe, which is capable of performing its functions efficiently and without appreciably increasing the resistance to escape of the steam, and made without separate internal parts.

In the accompanying drawings we have illustrated the preferred embodiment of our invention, and in the accompanyingspecification have described this embodiment in detail.

Figure 1 represents a vertical axial section of the exhaust head. Fig. 2 represents a vertical section on the line 2--2 of Fig. 1. Fig. 3 represents a horizontal section on line 33 of Figs. 1 and 2.

The same reference characters indicate the same parts in all the figures.

Referring to the drawings the device consists of a shell a which is preferably spherical in form, but may have other forms without departing from the spirit of the inven tion. This shell is adapted to be secured on the end of a steam pipe where such pipe projects externally from a building, through the wall or above the roof thereof, and for the purpose of such attachment it is provided with attaching means such as a flange b, or it may be a threaded nipple. In the bottom of the shell is an inlet 0 and in the top an outlet cl. Surrounding the inlet and rising therefrom within the shell is a tube or conduit 6, which also may be termed a deflector. The tube is curved through an arc of substantially 90 and has its outlet therefore in a plane approximately perpendicular to the plane of the inlet, and therefore parallel to the axis of the shell, which outlet is directed toward one side'of the shell, as shown in Fig. 1; Surrounding the outlet of of the shell, and depending therefrom into the interior of the shell, is a second tube, conduit or deflector f, which likewise is curved' through substantially an equal arc, but in the opposite direction. Thus the inlet of the conduit f is in a plane parallel to the outlet of the conduit 6, but laterally offset therefrom and directed toward the opposite side of the shell from that toward which the inlet conduit faces. The shell, flange and conduits are made in one solid piece as a single casting, the conduits being joined with the shell at the rims 'or peripheries of the inlet and outlet openings respectively, and being'also joined to each other where they are tangent on their convex sides. The tube ,f and outlet 03 are larger in diameter and cross-sectional area than the conduit e and inlet 0 respectively.

At diametrically opposite sides of the shell, and angularly midway between the inner ends of the tubes, are ribs or baflies g and 71,. These ribs follow the curvature of the shell through nearly the entire vertical extent thereof and lie in a plane passing through the vertical axis of the shell. At the bottom theshell is formed with a pocket 70 from which an outlet Z passes through the wall of the latter and is adapted to receive a drip pipe.

When this head is attached upon the end of a steam pipe it is so placed that the inlet 0 is in continuation with the bore of the pipe, whereupon the steam passes through the conduit 6 and is discharged therefrom squarely against the side of the shell. Its velocity is thus instantly destroyed and whatever condensed water or oil may be carried with it is arrested and caused to fall. The steam then travels around the shell until it finds the opening into the Outlet conduit f, through which it passes and out through the outlet. Thus traveling around the inside of the shell, the steam encounters the baffles g, h, and is again impeded, caused to change its direction and to lose Velocity. This gives, however, opportunity for water and oil which do not fall at the first check to be separated. In this way practically all the liquid is removed from the steam. In passing from the inlet conduit into the interior of the shell and thence through the outlet conduit, which is of larger siZe than the inlet, as before stated, the steam is allowed to expand. and so. to pass freely out of the exhaust head. For this reason the pressure of the steam in the exhaust head is not increased by reason of the checks and impediments placed in the way of its escape, and thus no increase of the back pressure of the engine is caused by the presence of the exhaust head. hen the steam finally escapes from the head, it is dissipated and absorbed by the atmosphere, and there is not sufficient moisture left to cause wetting of roofs and walls of buildings or the adjacent ground with either water or oil. Thereby wetting and rotting of the material of the building and accumulation of ice are avoided.

'Owing to the fact that the head with all its internal parts is made in one integral piece, and that the internal parts are not separate and independent, there is no dan- I ger of these internal parts working loose,

nor are spaces and joints left in which water can collect and cause corrosion.

We claim,

1. An exhaust head. comprising an outer shell having an inlet and an outlet, curved tubes extending from said inlet and outlet respectively into the interior of the shell and having their end openings within the shell turned away from one another, whereby the steam issuing from the inlet tube is required to change its direction before it canenter the outlet tube, and baffles interposed in the path of the fluid from the inlet tube to the outlet tube and arranged transversely to the direction in which the fluid flows.

2. An exhaust head comprising a spherical shell having inlet and outlet openings at diametrically opposite points, an inlet tube extending into the shell. from the inlet opening and being deflected so that its outlet is at one side of the line of openings and is in a plane parallel to such line, an outlet tube entering the shell from the outlet opening and oppositely deflected so that its admission orifice is at the opposite side of the line of openings from the inlet tube outlet, and baffles projecting from the inner wall of the shell between the discharge orifice of the inlet tube and the intake orifice of the outlet tube.

3. An exhaust head comprising a spherical shell having an inlet opening at its bottom, an inlet tube extending upwardly from and to one side of, said opening and having its discharge orifice directed toward one side of the shell, an outlet opening in the top of the shell diametrically opposite to the inlet opening, an outlet tube extending from the outlet opening downwardly and toward the opposite side of the shell from the inlet tube, said tubes being joined hermetically with the shell and surrounding their respective openings, a baffle projecting inwardly from the side of the shell intermediate those sides toward which the inlet and outlet tubes are respectively directed, whereby to arrest steam passing from the inlet tube to the outlet tube and a drip outlet from the bottom of the shell at the base of the inlet tube for draining off water separated from the steam.

4. An exhaust head comprising an outer shell, an inlet tube or conduit extending upwardly and to one side from an opening at the bottom of the shell, an outlet tube or conduit extending downwardly and toward the opposite side from the top of the shell, and a drip outlet from the bottom of the shell at the base of the inlet tube.

5. An exhaust head comprising an outer shell, an inlet tube or conduit extending upwardly and to one side from an opening at the bottom of the shell, an outlet tube or conduit extending downwardly and toward the opposite side from thetop of the shell, said tubes being tangent to each other at the center of the shell, and integrally united together at the tangent point and to the shell at their outer ends in one solid casting.

In testimony whereof we have afiixed our signatures, in presence of two witnesses.
