INTERNAL-COMBUSTION MOTOR.

To all whom it may concern:

Be it known that I, WILDER P. Bowers, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Internal-Combustion Motors; and I do hereby declare the following 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 internal combustion motors, and more particularly to means for introducing water or vapor into the cylinders thereof simultaneously and admixed with-the carbureted air for the usual and well-known purpose of eating out existing carbon deposits in the cylinders, and preventing such deposits therein.

The main object of the present invention is to provide a very simple and eflicient device for attaining the aforesaid objects, and

in which the feed of water or vapor is readily controlled by the operator from his seat in a motor-propelled vehicle to which the devlce 1 is particularly adapted.

A suitable embodiment of the invention is illustrated in the accompanying drawings in which:

Figure l is a fragmentary view partly in section and partly in elevation of the hood and motor of an automobile including the dash-board of the latter equipped with an apparatus constructed in accordance with my invention.

Fig. 2 is a detail transverse section of a water tank employed;

Fig. 3 is a detail view in elevation showing a dial and indicating hand associated with the valve controlling the supply froin the tank to the motor;

My said invention comprises a tank 1 adapted to contain water, which may be mounted at any suitable point, preferably on the dash-board, of a motor-propelled vehicle. Leading from the bottom of the tank 1 to a point higher than the latter is a pipe 2 which is coiled between its ends, as indicated at 3, about the exhaust manifold i of the motor, and which is connected at its other end, preferably by means of branch pipes 5, with the intake manifold 6 of the motor so as to uniformly distribute water or vapor supplied by said pi e 2 to said intake and among the several cy inders of the mo- Specification of Letters Patent.

tor. In this instance I have illustrated an ordinary four-cylinder motor, but it will be obviousthat my said device may be applied with equal advantage to motors having a greater or less number of cylinders.

Between the ends of the pipe 2 is a valve-.

' to indicate on the graduated scale 12, contained on a disk or dial 13 mounted on said dash-board, the extent to which the said needle valve is open. In the instance illustrated the indicating hand 11 indicates at zero on-the dial showing that the valve is closed. By turning the knob 10 to the right the' said valve may be very slightly opened,

or opened to a considerable extent, depending upon the amount of water or vapor desired to be introduced into the intake manifold and engine cylinders. Obviously the water must be drawn from the tank 1 by the communication of the artial vacuum existing in the intake maniiold, during operation of the motor, to the tank 1; thus drawing a, supply of water into the pipe 2. If the quantity admitted is very small, as by only very slightly opening the needle valve, such water will be almost instantly converted into steam in the coil 3, which is heated to a high degree by the exhaust manifold and the steam or vapor thus gen-' erated will be drawn into the intake'maniconverted into vapor or so-called wet steam which is advantageously introduced when the motor attains a high temperature, and the carbon deposits therein are unusually great and required to be quickly and completely removed.

While l have shown a suitable location for the tank 1 it will be obvious that in many instances it would he still more advantageous to locate the same below the level of the connection of the pipe 2 with the intake manifold so as to prevent a continuous siphon-flow into the manifold when the motor is idle in the event that the operator should forget to close theneedle valve.

I prefer to employ a needle valve, but any valve capable of relatively tine adjustment will he adapted to the purpose.

While I have shown a suitable einhodiinent ot the invention in the accompanying tllHVlIlQh, i1, will be obvious, of course, that the same is capable of variation and modification to adapt it to dif'tercnt l'notors and vehicl s without. (imparting from the invention as defined in the appended claim.

I claim as my invention:

In a propelling device for internal comhnstion automobiles, an internal combustion motor, a hood COVQI'lI'lg same; a cylindrical tank mounted in the space between the said motor and the hood and adapted to contain water, a connecting pipe therefrom leading to a valve-easing, a needle vol ve associated therewith and adapted to control the flow of water from the said cylinder tank, a handle for the said valve-stem ex tending through the dash-hoard 01"- the car, a knob and pointer associated therewith; a dial associated with the said pointer adapted to indicate the radial position of the said valve-stem, a pipe coil leading away from the valve-casing; said coil being wrapped around the exhaust manifold of the motor, continuation of the said pipe coil, duplicate branches leading therefrom, an intake main to the said motor, holes in the intake main adapted to receive. the said pipe connection and fastening means associated therewith whereby the branch inlets of the previously mentioned \\'ate1'-pipe are connected to the said maniilold.

l n testimony whereof I have signed my name in presence of two subscribing witnesscs.
