CARBON-REMOVING AND LUBRICATIN G ATTACHMENT FOR IN TERNAL-COMIBUSTION ENGINES.

Specification of Letters Patent.

Patented Dec. 16, 1919.

Application filed April 10, 1919. Serial No. 289,007.

To all whom it may concern:

Be it known that I, Jnssn W. SILVER, a citizen of the United States, residing at South Tacoma, in the county of Pierce and State of Washington, have invented new and useful Improvements in Carbon-Removing and Lubricating Attachments for Internal Combustion Engines, of which the following is a specification.

This invention relates to means for improving the operation of internal combustion engines by supplying thereto a carbon removing and lubricating vapor and thereby cleaning the cylinders of gasolenc or analogous internal combustion engines or motors and materially economizing in the use of gas in the operation of the engine or motor. One of the principal objects oi the invention is to provide an attachment that may be readily applied to gasolene engines of automobiles or other vehicles and also to stationary gas engines Without requiring any essential modification in the construction and arrangement of the parts of the engine and whereby a cleaning and lubricating vapor may be automatically supplied to the manifold of a asolene or internal combustion engine and distributed throughout the series of cylinders comprised Within the engine structure. With this and other objects and advantages in View, the inven tion consists of the construction and arrangement of the several parts which will be more fully hereinafter described and claimed.

In the drawings:

Figure 1 is an elevation of a portion of an internal combustion engine of the type usually employed in automobiles and showing intake and exhaust manifolds and a part of the dash of an automobile with the improved attachment applied thereto, and mainly shown in transverse vertical section.

Fig. 2 is a transverse vertical section taken in the plane of the line 22, Fig. 1.

Fig. 3 is an enlarged horizontal section taken in the plane of the line 33, Fig. 1.

The numeral 5 designates a container which is preferably formed of glass and supported by a band or clip 6 which is clamped around the said container and secured to the dash 7 b a suitable fastening means, as at 8. The and or clip 6 will be first secure-d to the dash and the container 5 subsequently inserted therein and secured, the said clip having angularly projecting ends 9 engaged by a clamp screw 10 whereby the said ends 9 may be drawn closely together to clamp the band or clip around the body of the container and reliably hold the latter in applied position. The container 5 has an upper reduced neck 11 which is corrugated or threaded to receive a chamber cap 12 and a horizontal partition plate or disk 13 which is firmly held in place on the upper end of the said neck within the lower portion of the chamber cap 12. The partition disk 13 practically forms a bottom for the chamber cap 12 and has a central depending tube 14 with a perforated flanged disk 15 at its lower end. On the tube 14 a short distance below the partition disk 13 is a perforated flanged disk 1(3,similar to the disk 15. The tube 14 with the disks l5 and 16 and the partition disk 13, as well as the chamber cap 12, are all formed of metal or other suitable material of a non-corrosive nature, and within the chamber cap 12 is a mixing chamber 17 of materially less diameter than the cap and whereby a passage 18 is formed between the mixing chamber and the cap, the passage 18 being obstructed in its complete continuity by depending flange 19 extending from one vertical wall of the chairs ber 17 downwardly to the partition disk 13. From the bottom of the mixing chamber a short length tube 20 extends and continuous through the partition disk 13, said tube terminating above the perforated flanged disk 16. The chamber cap 12 has a top inlet 21 with a removable cover 22 fitted thereover for filling purposes. Connected to the upper portion of the mixing chamber 17 is a tube or pipe 23 which extends through or across the passage 18 and outwardly through the adjacent wall of the chamber cap 12 and in part lies along and close to the exhaust manifold and is also connected to the intake manifold 24 as at 25, the pipe 23 having a valve 26 therein adjacent its point of attachment to the intake manifold for eontrollin communication of the mixing chamber 1% with the said manifold. Attached to and opening through the chamber cap 12 and communicatin with the passage 18 just above the obstructing or baflie flange 19 is a pipe 27 which extends along in engagement with the exhaust manifold 28.

oil being first prepared before depositing the same in the container. This combination of oils is supplied through the inlet 21 and passes downwardly through the chamber cap 12 to the upper end of the pipe 14; and then through the latter into the container and after the container has thus been supplied with the combined oils, the motor or engine, of which the manifolds 24; and 28 form parts, is started into operation and graduall slowed down, the valve 26 being closed w en the motor or engine is started. After the motor or engine has been suitably slowed down, orits running 'speed materially reduced, the valve 26 is opened and the suction of the motor or engine is ermitted to operate through the pipe 23. his suction of the engine or motor acting through the pipe 23 draws the air out of the mixing chamber 17 and causes the formation of a partial vacuum in the said chamber and creates a suction through the tube 20 relative to the contents of the container 5 and the outside air at the same time is drawn through thepipe 27 3 into the passage 18, this air, as will be understood, being heated. The hot air drawn into the passage way 18' through the pipe 27 is forced to pass upwardly over and down around the mixing chamber 17 by reason of the' baflle or obstru'cting flange 19 and by this means the said mixing chamber-is thoroughly heated. The heated air from the passage 18 continues downwardly through the pipe 14: and is delivered close to the bottom 0 the container 5 and then passes upwardly through the lower flanged perforated disk 15 which operates to divide the air into minute currents. These currents of heated air are drawn upwardly through the combined oils in the container 5 which causes the said combined oils to evaporate. The air currents ladened with the va rized oils then pass u wardly through t e erforated disk 16, t .e latter actin as asp ash to prevent 50 the air from'tfirowing the 011 in bulk upwardly into the mixing chamber 1'7. After passing through the perforated disk 16 the oil laden hot air currents then enter the said mixing chamber through the itnbe 20 which is materi heated and sheets a thorough mixture the air and oils. From the mixing chamber the vaporized oils and the air pass out through the pi 23 and are further heated and more comp etely va orized by the heated part of this pipe and t en conducted down to thexintake manifold 24 "whichstill further heats the mixture and creates a gas which unites with the gasolene gas after the latter haspassed through the usual form of and'at the same time a greas lubricant is carried into the cylinders an caused to engage the pistons of the motor or .engine with said gasolene gas and by this means in combination with the usual lubricating or oiling system, the pistons are thoroughly lubricated. The vaorized coal or kerosene oil that is carried mtothe manifold with the hot air and mixed with the gasolene gas serves as a cylinder cleaningmedium and also as an effective decarbonizmg agent and whereby the carbon deposits within the cylinders and adjacent parts areremoved and caused to pass out through the exhaust. The cleanin or decarbonizing element also serves to fieep the spark plug heads in cleanly condition with material advantage in the operation of the same. In addition to removing the carbon from the cylinder walls, it will also be understood that the pistons are relieved of carbon dc osits. The pipe 27 is held in connection with the exhaust manifold as shown by means of a suitable clamp 29, and the heat of this exhaust manifold is transmitted to the pipe and the air drawn through the latter is correspondingly tempered or heated.

From the foregoing it will be seen that the improved attachment may be readily applied to any type of automobile or other veicle motor or engine by simply securing the band or clip 6 to a support at a suitable distance from the intake and exhaust manifolds and connecting up the pipe 23 to the intake manifold and securing the pi e 27 against the exhaust manifold. It w' also be understood that the container 5 will have a suflicient capacity to render the operation thereof effective and it is proposed to modify the proportions, dimensions and general details of construction within the scope of the appended claims to adapt the improved attachment for various applications.
