Application led December 19, 1912. Serial No. 737,729.

To all 'whom it may concern.'

Be it known that I, WILLIAM B. PYLE, a at Robinson, in the county of Crawford, State ot Illinois, have invented certain new and useful Improvements in feter-Circulating Systems for Explosive-Engines; and I do hereby declare the folowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

' This'invention relates to improvements in water cooling systems for explosive engines.

The principal object of the invention is to provide such a system that a quantity of cool water from a supply tank will be drawn ,positively through the water jacket at each exhaust of the engine.

Another object is to provide a system of such construction and arrangement that cool water from the supply tank` will be drawn directly throughthe water jacket under the action of the exhaust from the' engine, and the ,heated water returned to the tank.

Other objects and advantages will be apparent from the following,descriptiony and :with particular reference to the accompanyin drawin the drawings the figure is a sectional v elevation of my Water circulating system.

Referring particularly to the accompanying drawings, 10 represents the cylinder of an explosive engine, which is provided with the usual exhaust pipe 11. The cylinder is also provided with the usual water jacket 12 in connection with which my device is used.

Disposed adjacent the engine is a water supply tank 13, and leading from the lower end of the tank to the lower side of the cylinder, and entering the water jacket, is a conduit 14 for conveying cool water from the tank to the'jacket, this conduit 14 entering the jacket of the cylinder near the outer end thereof.

Connected to the Water jacket on the -upper side of the engine near the rear end thereof isa conduit 15, said conduit extending a suitable distance above the water level of the tank 13, where it extends horizontally as indicated at 16 and is connected to a vertical pipe 17. Located in the pipe 15 just above the cylinder 10 is a check valve 1 which opens in a directionaway t; ii cylinder, and in one side of this check .f .n

is arranged a. pet cock 19. At a suitable point between the check valve 18 and the horizontal portion 16 is this pipe being arranged and extending horizontally toward anddischarging the water into the top of the tank. In this pipe 20 is a valve 21 opening toward the tank. Ex'- tending' from Athe exhaust pipes 11' is a pipe 22 and'connecting this pipe 22, by means oit' the union A23, to the pipe 17, is a pipe 24, this pipe being provided with a stop cock 25. By means of the valve the eifectiveness of the pull of the exhaust can be regulated.

The operation of the cooling system can be briefly described as follows: The exhaust flowing through the pipe 11 creates a vacuum". in the pipes 24C, 17, 16 and 15, and causes the water to, How directly from the bottom of the tank 13 through the pipe .14, the water jacket and up the pipe 15. This pipe 15 is of a height suiiicient to take a column of a return'pipe 20, Y

water equal to the amount of water which 1s 1n the water jacket and which has become hot. Upon closing of the1 exhaust air will rush into the pipes 22, 17 and 15 and exert pressure on andcause the same to iiow back through the pipe 20, into the tank. 'Return ot water into the jacket is prevented bythe Attention is particularly 'directed to the fact that applicant does not depend on gravity for the flow of the cold waterinto the water jacket, but the low is positive and` direct at each exhaust of the engine.

Attention is particularly called to the valve .25. By partially closing this valve the efectiveness of the -pull of the exhaust will be reduced. Were the valve to be moved into complete open position, the electiveness of the pull of the exhaust would be so great that the column of the water raised in the limb 15 might not be relieved ot' the suction to an extent sufficientv to permit it to i'all by gravity, the result being the continued suction of water until it iiowed r-h the 1'irnb 17 to the exhaust pipe 11 ctiveness of the system nan be gaged according to the speed of the engine.

It will also be noted that the exhaust wipe, as well as the point of connection oi the pipe 24C thereto is disposed below the engine cylinder, thereby precluding any possibilitvI yof entrance.` of water into the cylinder.

What is claimed is:

The combination with an explosive engine lncluding a water jacket .and an exhaust pipe, of a water circulatingsystem therefor comprising a water tank, a conduit connecting the lower end of the tank with the loweiiv side of ,the water jacket of the engine, an

other end 'connected to the side of the ex haust pipe below the cylinder of the engine, l

a conduit connecting the ist' named limb with the upper end of the tank, said irst named limb having an upwardly opening. check valve below the last named condult, a

check valve in the last named conduit opening toward the tank, and a 4valvein the second named limb of the U-shaped conduit foi' controlli'fig the eli'ectiveness of. the `suction from theexhaust pipe.

in testimony whereof, I aifixmy signature, in the presence ol two witnesses.
