AUTOMATIC DECARBONIZER FOR INTERNAL-COMBUSTION ENGINES.
Application filed July 3, 1916.
T 0 all whom it may concern:
Be it known that we, HARVEY E. SMITH and WILLIAM H. LAISURE, citizens of the United States, residing at Tacoma, in the county of Pierce and State of Washington, have invented certain new and useful Improvements in Automatic Decarbonizers for Internal-Combustion Engines; and we do 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 decarbonizers which are adapted to be attached to the intake manifolds of internal combustion engines, the object being to provide a solution which will act upon the deposits of carbon within the engine cylinders in order to loosen the same so that it may be blown out through the exhaust.
The primary object of the present invention is to provide a simply constructed decarbonizer of this character in which all the parts are assembled in one device in a compact manner.
An additional object is to provide a sight feed in communication with the fluid container in order that the operator may see if the solution is flowing properly or not.
With these and many other objects in view, our invention resides in the novel features of construction, combination and arrangement of parts which will be hereinafter more particularly described and claimed.
In the accompanyin drawings Figure l is a side e evation of a conventional internal combustion engine showing our improved decarbonizer attached to the intake manifold thereof above the carbureter;
Fig. 2 is a top plan view of the device removed;
Fig. 3 1s a central verticalsection on the line 3-3 of Fig. 2;
Fig. 4 is a transverse section on the line H of Fig. 2; and
Fig. 5 is a side elevation of the decarbonizer removed.
Referring more particularly to the drawing in which similar reference characters designate like parts throughout the several views, E denotes an internal combustion en- 'ne of ordinary construction having a plurality of cy inders G into which a combusti- Specification of Letters Patent.-

ble mixture from the carburetor A is conveyed by the intake manifold M. As shown 1n Fig. 1, the improved decarbonizer 1 is designed to be constructed. with the intake rmanifold at a point just above the communication of the carbureter therewith.
This decarbonizer comprises a substan tially cylindrical fluid container 2 having liquid within the container may be readily removed at any time. Air may be allowed to enter the interior of the container in order to prevent a vacuum forming therein by any preferred means such as a small vent opening in the top.
Formed integrally with the side wall of the container 2 adjacent the top thereof is a combined vacuum and sight feed chamber 8, the interior of which is preferably cylindrical in order to receive the usual cylindrical si 'ht feed lass 9. lhe to chamber 8 extends slightly above the top of the container and is internally threaded to receive a threaded disk 10 in the center of which a valve seat 11 is formed. From Fig. 3 will be noted that the sight feed glass 8 does not extend much above the sight openings 12 in the chamber and that this disk 10 contacts with the upper edge thereof in order to .hold it in operative position. Suitable packing is disposed at the top and bottom of the glass in order to prevent the decarbonizing fluid from leaking out through the sight openings. By this arrangement should the glass 9 become broken, it can be readily replaced by unscrewing the disk 10 and substituting a new glass therefor.
The valve disk 10 is placed below the top and the chamber 8 so that fluid from the corn tainer 2 may readily flow into the latter through a downwardly inclined port which is formed in an integral rib 1% which is disposed on the top 3. Une end of this port opens into the chamber 8 above the valve disk 10, while the other end communicates with the opening in spray pipe 15,
the latter being formed integrally with and depending from the top 3 to a point adjacent the bottom l as illustrated. in Fi 3.
In order to control the flow of liquid from the container 2 to the chamber 8, a needle valve 16 is provided for engagement with the valve seat 11. in the disk 10. The stem of this valve is threaded for engagement with the internal threads on a needle valve holder 17, the latter being threaded into the upper ends of the chamber 8. This holder 17 comprises a sleeve which is'both internally and externally threaded. and a packing nut 18 which is formed intermediate the ends of the sleeve and adapted to provide means to facilitate the engagement of a wrench with this holder in. order to thread the lower end of the same into the chamber 8, and also to hold a gasket 19 around the upper end of this chamber to prevent any leakage therefrom. The upper portion of the needle valve holder 17 has a packing gland 20 threaded thereon for the usual purpose. A handle 21 is provided on the upper end of the needle valve so as to readily perniit the same to be engaged or disengaged with the seat 11.
In order to permit the device to be attached to the intake manifold, a threaded nipple is formed integrally with the side of the chamber 8 opposite its connection with the container 2, this nipple being pro-- vided with a port 23 which communicates with a port A formed in an enlarged portion 25 of the wall. of the chamber Communication is had with the bottom of this chamber by means of a passage-way 26. It is obvious that by providing an opening in the intake manifold above the carburetor and tapping the same, the decarhonizer may be readily attached. Before the communication takes place, however, a spray nozzle 27 is tl'ireaded into the enlarged opening in the end of the nipple.
.fssuming that the device has been attached to the intake manifold M, the container 2 well filled. with a. suitable decarbonizing fluid, and after the needle valve 16 has been opened. the necessary extent. the automatic operation is as follows :--At each reciprocation of the pistons within the cylinder C a partial vacuum is created in the in take manifold M, thus drawing the requisite quantity of gas from the carbureter, and at the same time a vacuum is created in the vacuum chamber 8 of the decarbonizer, whereupon a quantity of fluid \vi l be sucked up the spray pipe ii -and into the port 13 from whence it flows out onto the disk 10 and drops from the nipple 10 formed on the lower side thereof. The amount of flow can be readily seen from the sight openings and regulated by means of the needle valve 16 After the fluid drops into the chamber 8 it is drawn through ports to the nipple 22 and from there to the spray nozzle 27. As the drops of liquid hang on the ends of the nozzle 27, the gases from the carbureter as they rush by will tend to atomize the decarbonizing fluid and carry it in the form of vapor to the cylinders, where it acts upon the deposits of carbon, loosening the same and permitting it to be blown out tl'irough the exhaust.
After the carbon has been entirely re moved, the dccarbonizing vapor formed from the fluid in the container Zwill pre vent the formation of further deposits, thus keeping the engine clea'n and allowing it to perform better service. From the foregoing description it will be seen that the device operates automatically, but is only in use during the operation of the engine.
