PBOPELLING MEANS FOR VESSELS.

To all whom it may concern:

Be it known that l, FRANK FANNING, a citizen of the United States, residing at Woodward, in the county of Woodward and State of Oklahoma, have invented certain new and useful Improvements in Propelling Means for Vessels, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to improvements in propelling means, especially adapted for vessels, and has for its object to provide means whereby a vessel can be propelled by means of steam or other aeriform fluid.

Other objects and advantages of my invention will appear in the course of the following specification.

In the accompanying drawings: Figure 1 is a longitudinal sectional view. taken through a vessel fitted with my propelling apparatus, a portion of the latter being shown in full, lines. Fig. 2 is a top plan view of a vessel similarly fitted. Fig. 3 is a longitudinal sectional view (enlarged) taken through portions of the propelling apparatus.

Referring to the drawings, which illustrate the preferred embodiment of my invention, 1 desi 'nates a vessel of conventional form. Krranged horizontally and longitudinally of the forward part of the vessel is an intake or supply pipe 2 which extends from its opening 3, beneath the water line at the bow of the boat to about the center thereof where it is connected by means of a union 4 to the reduced end 5 of an ejector 6. From the reduced portion 5, the ejector is substantially increased in diameter, as at 7 for a portion of its length and at 8, 8, the sides of the ejector are extended at right angles or perpendicularly to form a reservoir 9, which is substantially drum-shaped. vAttached to the bottom of the forward perpendicular side 8 of the reservoir 9 is a mixing chamber 10. The mixing chamber is constructed of a pair of conical frustums 11 and 12, respectively, similarly proportioned and inclined toward and connected to a horizontally-extending intermediate portion 13. The mixing chamber has formed as an integral portion thereof a discharge pipe 14:, which, as shown, is of a diameter substantially greater than that of the intake or supply pipe 2, but less than that of the reservoir 9.

Serial No. 509,491.

Formed in the top of the portion 7 of the ejector is a pipe or injector 15 which is inclined downward and curved and extends horizontally and centrally through the reservoir 9. The interior of the pipe 15 is formed with a converging bore, and hence thickened, from a point near the bend therein toward the end to form a nozzle 16 which projects into the conical frustum 11 of the mixing chamber 10 of the ejector. The interior thickening of the pipe 15 to form the nozzle 16 serves both to cause the steam to be emitted at a high velocity and at the same time serves to prevent any undue cooling thereof prior to its contacting with the water in the mixing chamber.

The horizontal intermediate portion 13 of the mixing chamber 10 is provided at its upper side with an integral circular rib or boss 17, which is provided with a suitably screw-threaded, circular interior. Arranged centrally within the circular boss 17 is an aperture 18 in communication with the interior of the mixing chamber and screwed into the boss is a valve casing 19 having an inverted truncated conical valve seat 20, the bottom of which registers with the aperture 18 in the mixing chamber. The side of the valve casing extends up above the top of the boss 17 and at its upper end is provided with an externally arranged rib or flange 21. The internal diameter 22 of the upper part of the valve casing, as shown, is greater than that of the upper end of the truncated conical valve seat 20, and is also beveled at its upper end, as at 23, for a purpose hereinafter described.

A valve 24: is positioned in the valve seat and is held in place by means of a coil spring 26 which surrounds a stem or short rod 27. One end of the coil spring rests on top of the valve while the other end thereof presses against the under side of a cross piece 28 to which the stem is connected or is an integral portion thereof. The lower suitably exteriorly threaded and adapted to engage the threaded portion thereof is an internally threaded collar 32 provided with an inturned flange 33 which contacts with the lower side of the flange 21 of the valve casing to lock the valve casing and associated members together. The pipe 30, as shown, is turned to one side-and passed through the side of the vessel, where it discharges. As is apparent the valve 2t can be set or regulated for any amount of pressure in the mixing chamber and will rise to allow the escape of the steam and water through the pipe whenever the pressure is excessive and overbalances the valve.

The steam or other aeritorni fluid fed through the injector may be a constant supply or it can be fed intermittently as desired.

hat I, claim is 1. In a propelling apparatus, an intake pipe, an ejector having a reduced end connected to the intake pipe, and an enlarged portion of greater diameter than the intake pipe, a reservoir communicating with and of larger diameter than the ejector, a mixing chamber connected at one end with said reservoir and consisting of a pair of conical trust-um shaped chambers connected at their smaller ends by an intermediate cylindrical portion, an inclined steam pipe extending downward in a curve through the enlarged portion of the ejector, and then horizontally through the reservoir and projecting into the mixing chamber, a relief valve for the mixing chamber, and a discharge pipe connected with said mixing chamber, and of greater diameter than the intake pipe, and of smaller diameter than the reservoir.

2. In a propelling apparatus, an ejector,

an intake pipe for said ejector, and a discharge pipe carried by said e ector, said discharge p1pe be ng substantially larger than said intake pipe.
