GAS SAVING ATTAGHMENT FOR INTERNAL COMBUSTION ENGINES Filed Sept. 27. 1 928 Patented Mar. 11, 1930 HENRY FRANK BEEMAN, 015 FORT COLLINS, COLORADO GAS-SAVING ATTACHMENT FOR INTERNAL-COMBUSTION ENGINES Application filed September 27, 1928. Serial No. 308,868.

This invention relates to a gas saving attachment for internal combustion engines and is designed primarily for use in connection with automobile engines.

One of the objects of the invention is to operation of the engine.

A further object is to provide simple means for washing the. vapor so as to prevent the particles of dust from being carried into the engine and injuring the same.

A further object is to supply water vapor to the intake manifold, thereby permitting a considerable reduction in the amount of gas used and also practically eliminating oarbon deposits.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings, the preferred form of the invention has been shown.

In said drawings,

Figure 1 is view partly in elevation and partly in section of a portion of an automobile engine having the present improvements combined therewith.

Figure 2 is a perspective view showing one way in which the intake pipe of the attachment can be connected to the overflow pipe of the radiator.

Referring to the figures by characters of reference A designates a portion of the intake manifold of an automobile engine and B designates a portion of the radiator provided with the usual overflow pipe G.

The attachment constituting the present invention includes a tubular body 1 preferably formed of thick glass the ends of which are seated in grooves 2 formed in heads 3 and 4:. These heads are drawn toward each other by tie rods 5 and, by first placing gaskets 6 upon the ends of the tubular body 1, the ti ghtening of the rods 5 will-result in the formation of a shield chamber 7. Opening through i the upper head 3 of the attachment is a nipple 8 to which is connected an outlet tube 9 which can be of copper or other material easily bent. Another tube 10 is suspended within the chamber 7 from the head 3, the upper end of this tube being coupled as at 11 to a vapor supply tube 12 likewise preferably formed of copper or other material easily bent. An air inlet tube13 depends from the head 3 and has a check valve 1 1 normally clos ing the upper or outer end thereof. The

lower end of this tube 13 is located at a considerable distance above the lower end of the tube 10 and mounted to slide within the air tube 13 is a rod 15 projecting upwardly from a float 16. This rod is so proportioned that when the float 16 rises to a point close to the lower end of the tube 13, said rod 15 will come against and unseat the check valve 14, thereby permitting air to enter the chamber 7 through the tube 13., Normally, however, this valve is in closed position.

When it is desired to use the device constituting the present invention a small opening 17' is drilled into the overflow pipe 0 and an elongated opening 18 is out into the tube 12 near its free end. A screw plug 19 which is coupled in any suitable manner to one end of the tube 9 is screwed into an opening 20 drilled in the wall of the intake manifold A. The opening 18 in tube 12 is placed where it will communicate with the aperture 17 and thereafter said tube 12 is fastened securely to the overflow tube 0 in any suitable manner. For example strong insulating tape indicated generally at 21 can be wrapped about the engaging portions of the tubes 12 and C so as to hold them together firmly, close the free end of the tube 12 and prevent leakage of air into the tube 12. With the parts thus assembled and the body land heads 3 and 4 mounted in any preferred manner adjacent the ention between the upper portion of said chamgine, the attachment is ready for use. It is her and the intake manifold of an engine.

rst necessary to pour a mixture of heavy oil In testimony that I claim the foregoing as into the chamber 7. This mixture is prefermy own, I have hereto affixed my signature. ably made up of one part coal-oil and two HENRY FRANK BEEMAN. 70 I parts castor oil. A suflicient amount of the mixed oil is used to submerge the lower end if of the tube 10. While the engine is in use a suction will be set up from the chamber 7 10 through the tube 9 to the intake manifold A 75 and as the check valve 14 is normally closed, this suction will result in the withdrawal of an amount of vapor from the top ofthe radiator B through the upper portion of the over- 15 flow pipe C, the apertures 17 and 18to the S0 tube 12 and thence into the bottom. portion of chamber 7. Here the vapor will rise through the oil at which time any dust or other objectionable particles commingled therewith 20 will be precipitated while the pure vapor will 35 be free to flow into the tube 9.

Should there be an undesirable accumulation of water due to the condensation of vapor in the chamber 7, the float 16 would zti'rise sufiiciently to lift rod 15 and valve 14 90 and thus admit air into the chamber 7 so that l the'operation will continue without causing l the chamber to become flooded to an objectionable extentbyithe water. [Air thus admitted 'willalso prevent the structure from vas overheating.

It will be understood that the pipe or tube 1'3 acts as a guide for the rod'15.
