CARBON-REMOVING MEANS FOR INTERNAL-COMBUSTION ENGINES.

Specification of Letters Patent.

ieaamaea Nev. 1., i921.

Application led February 28, 1920.` SerialNo. 362,096.

To all whom it may concern:

Be it known that I, FRANK P. HOWARD, a citizen of the United States, residing at Lisbon, in the county of Grafton and State of New Hampshire, have invented certain new and useful Improvements in Carbon-Removing Means for Internal-Combustion Engines, of which the following is a speciication.

This inventionrelates to means for removing the carbon from the cylinders of instances into the cylinders. Attemptsvhave hitherto been made to inject cleaning liquids through spark plug openings, or by means of priming cups, but liquids so introduced are not properly distributed, and do not produce satisfactory results.

Tt is Vthe primary object of the present invention, therefore, to provide simple, convenient, and eflicient means for eHectively introducing into` an 'engine manifold a suitable hydrocarbon or other substance forv cleaning the cylinders.

' A further object is to provide means whereby such :cleaning agent may be supplied to the manifold in either liquid or i i vapor form, as desired, the vapor being of'a character either the same as or different from the liquid. 4 V

A still further object is to provide kan improved mechanical construction of vapor forming and liquid delivery apparatus peculiarly adapted for the above purposes.

With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts hereinafter described and claimed, and illustrated in the accompanying drawing, in which Figure 1 is a longitudinal vertical section v shown in elevation and a portion of an en-V gine manifold being illustrated inv dotted lines;

Fig. 2 is a side elevation of my improved device, and

Fig. 3 is a front elevation thereof, showing the manner of supplying liquid thereto.

Referring to the drawings in` detail, my

Vimproved device comprises a container or receptacle 1 preferably made of metal and shown as rectangular in shape. This container has a bottom 2 provided with an annular flange 3 within which snugly fits the upper end of a cup 4 preferably formed of glass. A gasket 5 of rubber or the like may be employed to insure a tight seal between the upper edgeof the cup 4 and the container 1. Y

The cup 4 is supported by means of a Vsaucer or stirrup 6 in which it rests and the .stirrup is held by means of a strap 7 passing under the same, the free ends of which are secured to plungers 8 working freely in guide tubes` 9 extending through the container or receptacle 1. The upper ends of these tubes are preferably closed as by means of removable plugs 10. The upper end of each plunger 8 is provided with an enlarged head 12, and each'tube 9 carries an inwardly extending annular shoulder 13. Between Ythe head 12 and shoulder 13 is a helical spring 11, the yresiliency of which serves to exert a yielding upward pull on the strap 7, thus urging the cup 4 against the gasket 5 and holding it firmly in position, notwithstanding the severe vibration to Vwhich it is subjected.

Extending vertically down through the receptacle 1 is an airinlet tube 14 having an enlarged screw threaded portion 15, engaging the top of the receptacle. Thus tube passes down through the bottom of the receptacle into the cup 4, its end terminating a short distance above the bottom of the cup. The bottom 2 of the receptacle Vis provided with va plurality of perforations 16, so that the interior of the cup 4 is in free communication with the interior of the receptacle. The cup and receptacle when in use are partially filled with a suitable liquid, such as kerosene, to a height as indicated for example at m in Fig. 1. The receptacle is further provided with a drain cock 17 protecting cap 28 being, of course,aremoved.

and a waste or overflow outlet 18. Screw bolts 19 having nuts 20 are also preferably provided so that the device may be conveniently attached to the dash board or other part of an automobile.

Surmounting the receptacle 1 is an air dome chamber formed by an annular upstanding flange 21 and an inverted cup or cap 22 snugly tting such flange. The top wall of the container 1 is provided wit perforations 23 affording communication between the interior of the container and the dome or chamber above described.

Carried by the wall of the lair dome or cap 22 is a pipe 24 terminating on the inside of the cup 22in a beveled end 24. A pi e or tube 25, which may be of copper, ru ber or other suitable material, extends from the pipe 24 to the engine manifold 26 at a point between the carbureter and cylinders,U the passage of fluid through such pipe being controlled by means of a pet cock 2 5, operated by a pull rod 25? in anyvsuitable manner. Y

Obviously when this 'pet cock is opened and the engine is running, the suction created by the engine will cause air to flow down through thel tube 14 and bubble up through the liquid.A contained in the receptacle, such bubbles being readily visible through the glass cu 4. This produces a vaporization of the liquid, and thel vapor passes up through the perforations 23 and thence through the pipes 274 and 25 to the engine cylinders, where it assists in cleaning and removin the carbon therefrom. v

Ifit is desired to supply kerosene or other substances in liquid form to the manifold, the`upper end of the tube 14 is closed by means of a plug 14, as shown in Fi 3. A short piece of flexible hose 29 is t en attached to a nozzle 27 carried by the cap 22 immediately above the kend of pipe 24, the

The free endof'the hose 29-is immersed in kerosene or other liquid contained in a cup 30, which Vmay beheld inthe hand or otherwise suitably supported. The suction of the engine will, therefore, Icause liquid l to4 be drawn in through the hose 29 and nozzle 27, from which it will pass into the pipe 24 and be conveyed tothe manifold.V

This operation of supplying liquid to the engine should be'performe'd,'of course, when the automobile is not in motion, and` whilev p the engine is either running slowly or being cranked. v Y Y It will beunderstood that. if it is desired to remove the glass cup 4,'this may .be accomplished by pulling down on the stirrup 6, and swinging it t0 one side, the springs 11 yielding suliciently to permit the edge of the stirrup to clear the bottom of the cup.

It will thus be seen that I have provided a simple and efficient device whereby either liquid or vapor may be supplied to an engine manifold as required, and thence distributed to the cylinders and it' is thought that the many advanta es of my invention will be readily appreclated without further discussion. f

What I claim is:

1. The combination with a liquid receptacle having, two communicating compartments, one partially filled with liquid, and the other having a suction pipe extending therefrom, and provided with a liquid inlet, an air inlet pipe discharging below the level of the liquid in said first mentioned compartment, andmeans for closing said air inlet pipe s0 as to cause said suction pipe to draw in liquid from another source through said liquid inlet.` y I 2. A hydrocarbon Vapor generator comprising a receptacle partly filledy with liquid hydrocarbon, a suction pipe extending from the upper part of said receptacle, a glass cup fitted in the bottom of said receptacle and communicating therewith, and an air inlet tube passing down into said receptacle and terminatingin saidl cup, whereby suction through said pipe causes air to iow in through said tube and bubble up through the liquid, such bubbles being visible through said glass '.cup. i

,3. v hydrocarbon vaporgenerator comprisng a receptacle partly filled with liquid hydrocarbon, a, suction pipe extending from the upper part of said receptacle, adetach able glass cup fitted to the vbottom of said receptacle and communicating therewith, and a stirru-p supporting said cup.

4. A hydrocarbon vapor generator comprising la receptacle partly filled with liquid hydrocarbon, a suction pipe vextending from the upper part of said receptacle, a cup fitted in the bottom of said receptacle and communicating therewith, a stril'uk in vwhich `said cup rests, and means for res iently'supportingl said stirrup so as to lhold said cup in osition. I'

n Vtestimony whereof I aix my signature in presence of two witnesses.
