INTERNAL COMBUSTION ENGINE CLEANING DEVICE Filed NOV. '7, 1928 INVENTOR We BY t a? l ATTOR N EY Patented Dec. 30, 1930 PATENT FFICEy l FRANK F. COWHERD, OKF CHICAGO, ILLINOIS INTERNAL-COMBUSTION-ENGINE-CLEANING DEVICE Application led November This invention relates to certa-in novel improvements in internal combustion engine cleaning devices, and has for its principal object the provision of an improved construction of this character, which will be highly eficient in use and economical in manufacture.

The efficiency of internal combustion engines is greatly impaired by carbon accumulations in the explosion chambers and by accumulations around the valve seats and around the guiding members for the valve stems. y

I have found that by introducing a suitable luidinto the cylinders of such engines that these accumulations may be obvated and therefore, the efficiency of the engine may be maintained ata maximum. It is therefore the salient object of my invention to provide a construction which will permit the introducing of such a cleaning fluid into the combustion chamber of an internal combustion engine.

An object of my invention ancillary to the foregoing is to provide a device through which airV may pass to pick up the cleaning Huid and convey the same into the intake manifold of the engine.

Other objects will appear hereinafter.

The invention consists in the novel combination and arrangement of parts to be hereinafter described and claimed.

The invention will best be understood by vreference to the accompanying drawings wherein a preferred form of construction is shown, and which:

Fig. 1 is a side elevational view depicting v a preferred form of construction for my invention; Y

Fig. 2 is a vertical sectional detail view taken substantially on the line 2 2 on Fig. 1;

Fig. 3 is an elevational view depicting a preferred form of construction for my device in association with an internal combustion engine; and

Fig. 4 is a plan view of the device illustrated in Fig. 1.

body portion Vwhich is preferably formed of a transparent material for a purpose to be set forth hereinafter. The member 10 is substantially cylindrical in formation and at the lower end thereof, the bottom member 11 is mounted, which preferably has an upwardly extending flange 12 that engages the periphery of the body member 10. At substantially in the midpoint in the bottom member 11 on the inner side thereof a boss 13 is provided o0 through which an opening 14 extends to the outer side of the bottom member 11 for a purpose to be set forth presently. A head construction 15 is provided which is mounted at the upper end of the cylindrical member 10 65 and this head construction 15 includes a depending flange 16 which corresponds to the flange 12. A supporting bracket 17 is provided which is employed in the mounting of the construction. An vaxially arranged bore 18 extends through the head member 15 and terminates in a screw-threaded portion 19 at the inner' end thereof. A pipe member 20 has one end thereof connected in the screwthreaded portion 19 and the opposite end thereof is rested on the inner surface of boss 13. A bolt member 21 is passed through the opening 14 which screw-threadedly engages the inner surface of the pipe member 2O and thus a differential clamping action is created so which serves to hold the bottom member 11 and head member 15 in position on the body member 10.

Into the outer screw threaded end portion y22 of the bore 18 a plug member 23 is fitted. 85 An opening 24 extends axially through the plug member 23 and this opening is of relatively restricted size so as to be substantially capillary. Adjacent the lower end of the pipe member 20 openings such as 25 are provided for a purpose to be set forth presently.

An outlet passage 26 is provided in the head member 15 which opens into a conduit 27 that is connected into the head member 15. A conduit structure 28 connects the conduit C5 member 27 with the intake manifold 29v of an internal combustion engine.

In operation, a vacuum is created in the intake manifold in a manner well understood in the art. This causes air to be drawn 1 1li Gil through the opening 24, passage 18, pipe member 20, and out through the openings 25 `into theiinterioi' of the body'meniber l0.

Prior to this time the plug member 24 Will have been removed and the body member l Will have been filled with a cleaning fluid having the properties set forth hereintofore and I have found that kerosene is Vtherein to Which members may be connected to connect said chamber with the intake manifold of the internal combustion engine.
