EXPLOSlVE-ENGINE.

SPECIFICATION forming part of Letters Patent No. 738,860, dated September 15, 1903.

Application filed January 8, 1902. Serial No. 88,849. (No model.)

To all whom it may concern:

Be it known that we, WILLIAM W. TUoK, residing; at Richmond Hill, Queens county, ABBOT AUGUSTUS LOW, residing at Horseshoe, St. Lawrence county,and AUGUST IVASSMANN, residing at Halletts Point, Astoria, Queens county, State of New York, citizens of the United States, have invented certain new and usefullmprovements in EXp1osive-Engines,of which thefollowingisa specificatiomsufficient to enable others skilled in the art to which the invention appertains to make and use the 7 same.

against a reciprocating piston and are de-j signed to obviate back pressure and noise by condensing, absorbing, and withdrawing the products of combustion through the medium,

of a stream of water flowing under pressure, substantially as hereinafter stated.

The invention consists, essentially, in combining with the exhaust for the products of combustion a conduit through which water is passed under pressure in such manner that the products of combustion are caused to impinge upon the flowing water by which they are withdrawn and discharged, the continuously-flowing stream of water closing the exhaust-passage to the atmosphere, so that there can be no back pressure and resulting noise, vibration,or loss of power, as hereinafter more clearly set forth.

In the accompanying drawings Figure 1 represents a front elevation of our improvements as applied to a gas engine in which kerosene-oil is used, although it is to be understood that our improvements may be used inv conjunction with any form of gas or explosive. Fig. 2 is a sectional detail of our ejector.

E is the engine of any design or manufacture, as before indicated, in which the power is generated by the explosion of a hydrocarbon gas or vapor or any other form of explosive producing products of combustion.

c is the ordinary exhaust pipe or passage.

P is a pump of any desired form or corn struction, operated preferably by means of an eccentric 0 upon the power-shaft S of the engine, although this is not essential, since the pump or equivalent device may be operated by any mechanical means, if desired, the essential feature in this connection being the provision of means whereby a continuous flow of water or other liquid may be maintained within the pipe or conduit A. In the drawings a pump P of ordinary and well-known construction is indicated, supplemented by check-valves p p in the usual way, a regulating-valve V being added and interposed between the check-valve p and discharge-ejector I) for the purpose of regulating and adjusting the flow of water delivered by the pump. The ejector D may be made in various ways mechanically and the form herein shown is presented by way of illustration only, since the essential feature of construction consists in means for passing a stream of water across the opening e in the lower end of the exhaust 6, through which the products of combustion are discharged from the engine E.

It is obviously preferable to have the lower end of the conduit for the discharge of the products of combustion run parallel to the adjoining portion of the water-conduit, so that the flow of gas and liquid will be in the same direction as indicated, although the products of combustion may be caused to impinge against a stream of water at any desired angle without departing materially from the spirit and intent of our invention. In the drawings we show the ejector D as interposed between the lower end of the conduit c and the upper end of the water-pipe A, said ejector having the two passages d and c merging into each other and into the common discharge or outlet D, by which the combined water and products of combustion are conducted to the desired point for ejectment. The tendency of the constantlyflowing stream of water in the passages A, (Z, and D is to create suction through the discharge-passage 6, so that the products of combustion as they are forced through the discharge-pipe c readily enter into and are absorbed by the stream of water, and this without direct impact against the atmosphere. The stream of water also forms a continuous seal to the end of the discharge-pipe (2, so that there can be no communication with the atmosphere under any conditions, and consequently no back action and no noise or vibration.

By our method the removalof the products of combustion is complete and effective, no bad or impure air being left within the cylinder or exhaust-pipe to contaminate and impair the efficiency of succeeding charges, rendering the operation of the engine more economical and effective, as has been proved by experiment and use, while, as before stated, avoiding back action, vibration, and noise, the stream of water sealing the dischargepipe, lubricating the same, and tending constantly to suck out and absorb the products of combustion.

What we claim as our invention, and desire to secure by Letters Patent, is

1. The combination with an explosive-engine, of an exhaust-pipe leading therefrom, an ejector connected with the lower end of said exhaust-pipe, said ejector having a diaphragm extending beneath such connection with the exhaust-pipe, means for forcing a stream of water from beneath said diaphragm across the discharge-opening of the exhaust from said ejector above the diaphragm, and a common discharge for the exhaust and water from said ejector, substantially as shown and described.

2. In an explosive-engine the combination with the exhaust-pipe and a water-pipe, of an ejector interposed between the two and having passages separated by a partition, one of said passages being connected with the exhaust-pipe, and the other with the dischargepipe from said pump, and a discharge-pipe connected with the discharge end of the ejector in line with said partition whereby said partition constitutes a water seal extending across the discharge end of the passage connected with the exhaust, substantially asv and for the purpose specified.

The combination with an explosive-engine and its exhaust-pipe, of a water-pump connected directly with the power-shaft of said engine, a pipe leading from said pump, a regulating-valve in said pipe, an ejector connected with said pipe and with the exhaust-pipe and having a portion extending at substantially right angles to said pipes and provided with a longitudinal partition extending from the point of junction of its curved branches, and a common discharge-pipe for said water and exhaust connected with the discharge end of the ejector with said partition extending substantially in axial line therewith, whereby the waterfiowing through the lower branch of the ejector creates a suction through its upper branch and the water forms a continuous seal to the end of the discharge-pipe and to the exhaust, all substantially as shown and described.

4. The combination in an explosive-engine and with the exhaust-pipe leading therefrom, of an ejector having upper and lower branches for connection with said exhaustpipe and with a pipe leading from a pump and a lateral branch at right angles thereto for connection with a discharge-pipe common to both of said branches, -said ejector being further formed with a longitudinal partition integral with and joining the said upper and lower branches at their junction and extending to a point approximately at the outer end of its lateral branch to constitute with the water beneath the same a continuous seal to the end of the discharge-pipe from the exhaust of the engine to avoid back action and vibration, all substantially as shown and described. I

5. As an improved article of manufacture, an ejector attachment for explosive-engines comprising in a single integral element an ej ector-bodyhavin g upper and lower branches oppositely curved from the body portion which latter is contracted at its outlet end, and a longitudinal partition joining the adj acent curved portions of the upper and lower branches and extending lengthwise of the body portion to the point where the same is contracted and the whole adapted to serve substantially as and for the purpose specified.
