Patented Oct. 2 8, 1930 PATENT OFFICE cAanon-nnnovme DEVICE Application filed. June as,

This invention appertains to an attachment for internal combustion engines and more particularly to a device which can be incorporated with the existing type of internal 5 combustion engines without change thereto for efiectively removing carbon deposits therefrom.

One of the primary objects of the present invention is to provide novel means for in to troducing a vapor directly from. a burning substance arranged exteriorly' of the engine I into the intake manifold of the engine while the engine is in operation, the vapor acting upon the carbon deposit to loosen and remove the same from the various engine parts. Another salient feature of the invention is the provision of a carbon removing attachment for internal combustion engines embodying a container for receiving an inflammable substance with means for collecting vapor from said substance and for introducing said vapors into the intake manifold of the engine.

A further object of the invention is the provision of novel means for igniting said inflammable mixture by the operator of the engine without diificulty or inconvenience, when it is desirable to remove carbon from the engine.

A further object of the invention is the provision of novel means for constructing the container for receiving the inflammable mixture to permit the free circulation of air therethrough with means from the intake manifold for causing a suction in said container for creating a draft therethrough in connection with means for igniting the inflammable mixture disposed in said container.

A further object of the invention is the provision of novel means arranged in predetermined relation to the container for eliminating any exterior fire hazard.

A still further object of the invention is to provide an improved carbon removing attachment for internal combustion engines of I the above character, which will be durable and eflicient in use, one that will be simple 7 and easy to manufacture, and one which can be placed upon the market and incorporated 1928. Serial No. 287.877.

with a conventional automobile internal combustion engine at a small cost.

With these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described, claimed, and illustrated in the accompanying drawing, in which drawings Figure 1 is a fragmentary side elevation of an automobile showing parts thereof broken away and in section and illustrating my improved attachment incorporated therewith.

Figure 2 is an enlarged side elevation of the novel container forming a part of my attachment showing the same in connection with the dash-board, the dash-board being shown in section.

Figure 3 is a similar view with the container in longitudinal section.

Referring now to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views the letter A generally indicates a motor vehicle including the usual internal combustion engine 5, dash-board 6, and instrument panel 7. As shown the internal combustion engine includes the usual cylinders 8, an intake manifold 9 having connection with a carburetor 10.

My improved attachment for removing carbon from the engine is generally indicated by the reference character B and the same embodies a container 15 which can be formed of any desired material and of any desired size. As shown this container embodies a cylindrical side wall 16 and a lower disc shaped bottom wall 17 which is provided with a plurality of air openings 18. This bottom wall and its axial center can also be provided with an internally threaded nipple 19 for a purpose, which will be later described. The up per end of the container can be provided with a removable cover 20 so as to permit the introduction of an inflammable material 21 therein. The cover 20 can be removably secured .in position in any desired way such as by the use of mating threads on the container and said cover. The material 21 utilized in this apparatus is of a special character and forms the subject matter of my copending application filed June 23, 1928, Serial #287,878 hazard, I provide a closely woven wire mesh This material preferably consists of pure charcoal impregnated with salt. The charcoal is utilized for supporting combustion and allows the fumes from the salt to act on the carbon deposits in the engine.

The container can be secured in any desired position on the automobile adjacent to the engine 5 and in the present instance I have shown this container connected to the inner face of the dash-board 6, by the use of a suitable retaining bracket 22.

If desired the material can be held slightly spaced above the bottom wall 17 by the use of a suitable grate or screen (not shown), in the drawings.

The material in the container is adapted to be ignited and the vapors caused by the burning of the material are delivered directly to the intake manifold 9 of the internal combustion engine. As shown I have provided a conduit pipe 23 leading from the covor 20 to the intake manifold 9directly above the carburetor 10. This conduit pipe 23 can be detachably connected with the cover in any way so as to permit the easy removal of the cover 20 when necessary or desirable.

It is obvious that when the engine is in operation a suction will be created within the container 10 causing air to flow into the container through the openings 18 and the creation of a draft through said container. This suction can be controlled in any preferred way, and in the present instance I have shown a pet-cock 24 incorporated in the length of the conduit pipe 23, and this pet-cock can be rod 26. This rod can be extended through the instrument panel 7 of the automobile so as to permit t e convenient operation of the pet-cock by the operator of the machine without leaving his seat.

The material in said container can be quickly ignited in any desired way, but I prefer to use a substantially conventional spark-plug 27 for this purpose and this spark-plug can be threaded into the nipple 19 as clearly shown in Figure 3 of the drawings. The high tension current necessary for operating the spark-plug can be obtained from any desired source from the vehicle and the same does not form the subject matter of this application, but, as shown, a wire 28 is connected with one of the plugs of the engine and said wire is led to the central electrode of the plug 27. A manually controlled switch 29 can be incorporated in the length of this wire and the switch can be mounted on the instrument panel 7 for convenient operation by the operator of the vehicle. The other electrode of the plug is grounded, through the container, pipe 23 and then to the engine block.

In order to reduce the possibility of fire shield 30 for the lower end of the container and this shield is shaped as to entirely house the lower end thereof and the openings 18. This shield can be removably held in position in any desired way and in the present instance I have shown the shield connected with the container by the ordinary bayonet slot connection 31.

In the use of my improved attachment, the same is incor orated with an automobile, as shown, and tlie material 21 is placed in the container 15 through the open end thereof by the removal of the cover 20. When the enine becomes ladened with carbon, it is merey-necessary for the operator of the vehicle to pull the rod 26 to open the pet-cock 24 and to 0 rate the switch 29 to cause the operation of t e plug 27. The sparking of the plug 27 will i nite the material 21 and the vapors from t is material will flow through the conduit pipe 23 and into the intake manifold 9. It is understood that the engine is o erated during the use of the attachment. he vapors containing the salt fumes flowin into the intake manifold with the fuel mixture will act upon the carbon in the engine to loosen theearbon and remove the same from the electrodes of the spark-plugs, the valves, the piston, and the like, it bein known that salt effectively removes carbon rom internal combustion engines.

From the foregoing description it can be seen that I have provided a novel attachment of exceptionally simple and durable character which can be readily incorporated with an provided with d p ndi h dl or nk automobile, by the ordinary layman, without 25, to which can be connected an operating change h r o.
