ATTACHMENT FOR MOTORS.

Application filed August 12, 1919.

To all whom. it may concern:

Be it known that we, GEORGE W. FoKnnN, a citizen of the United States, and ALFRED Amrenusrnn, a citizen of Austria, residing at Detroit, in the county oflVayne and State of Michigan, have invented new and useful Improvements in Attachments for Motors, of which the following is a specification.

This invention relates to an attachment for a gasolene engine, wherein a predetermined quantity of water or water vapor is automatically delivered to the engine in each suction stroke of the piston, which water vapor tends as is well known to the elimination of carbon deposit within the cylinder.

he invention is capable of use in connection with the suction, vacuum, or damp air system and comprises a unitary member which may be readily applied in position on any motor having an intake manifold, and which is so constructed that the water utilized may be taken from the usual circulating system of the engine or from an independent source of supply.

In the drawings:

igure 1 is a view in elevation illustrating an engine diagrammatically and showing the position of the attachment with relation thereto.

Fig. 2 is an enlarged plan view of the attachment.

Fig. 3 is an enlarged elevation of the attachment.

Fig. 4 is a vertical section of the attachment.

Fig. 5 is a horizontal section of the attachment.

Fig. 6 is an end view illustrating particularly the needle valve and its adjustment indication.

The improved attachment comprises a body 1 approximately circular for a greater portion of its length and having a lateral offset 2 at one end. The body has a central bore or channel 3, which at one end is enlarged to provide a receiving chamber 4, and at the opposite end communicates with a similar bore 5 in the lateral offset 2. The communication between the chamber 4 and the bore 3 beyond said chamber is controlled through a needle valve 6 cooperating with a valve seat 7 formed in the bore 3, said needle valve beyond the chamber having threaded connection as at 8 with an extension 9 of the body, a lock nut 10 cooperating with said Specification of Letters Patent.

extension and serving to valve in adjusted position. has an operatlng lock the needle The needle valve pin or handle 11, on the outer surface of which is arranged a dial 12. This dial is marked to indicate the drops passing the point of the needle valve in a particular period of time, as one minute, and the marks on the dial are, of course, adapted to register with any fixed pointer at 13.

The chamber 4: communicates with a bore 14; extending through the top of the body and connection is here made as thrmigh a pipe 15, with suitable connectors in any source of water supply. This may be, and is preferably an appropriate part of the water circulating system, although it is, of course, understood that an independent water container may be used if desired. lateral offset portion of the body is preferably inclined with respect to said body and its bore 5 is formed slightly beyond its juncture with the bore 3 with a valve seat 16 adapted to cooperate with a valve 17. The extension 2 is cored in line with the bore 5 as at 18, the wall of which is threaded to receive an adjusting member 19, having a stem :20. The valve 17 is also provided with a stem 20. which, together with the stem 20 acts to hold a spring 20 in position to bear upon the valve. By adjustment of the member 19, the tension of the spring can be so regulated that the lift of the valve 17 may be controlled or the said valve may be held firmly seated.

The extension 2 beyond the valve seat is formed with a channel 21, communicating with the channel 5. The body is provided at this point with a threaded extension 22 adapted to engage with the intake manifold 23 of the carburetor.

The outer side of the body is provided vith a threaded opening 24, adapted to re ceive a screw 25 having a headed portion 26 beyond the body. The opening 24 communi cates with the bore 3 between the needle valve seat and the valve 17. The screw 25 provides means for testing the operation of the apparatus at any time, as upon the removal of this screw, the passage of water through the bore 3 may be indicated by leakage of such water through the opening 24:, so that the user will know that the device is in operation.

If the needle valve set screw admits the desired quantity of water past the same, each suction stroke of the piston will lift the valve 17 from its seat and draw into the cylinder with the incoming gas a certain proportion of water from the apparatus here described. This water becoming vaporized will materially aid in gasifying or cleaning of the carbon within the cylinder and the continued use of the device will maintain such cylinder clean, while at the same time adding that vapor to the gas which as is well known increases the power thereof. Therefore the device is in eifect both a gas saver and an economizer, and as it is apparent from the above description, may be readily applied to any gasoline engine having an intake manifold, as all that is necessary is the formation of a threaded opening in the latter, and the connection of the inlet pipe 15 to the radiator or to an lily dependent source of water supply.

In the use of the invention in connection with a suction system, the water has a tendency to pass the valve and enter the engine cylinders, as the level of the water is higher than the vaporizer, when the latter is connected to the engine radiator. To prevent the passage of the surplus water into the engine cylinders there is provided a safety valve, which is formed of .a ball27 located in the chamber 28 and adapted to engage a seat 29 when acted upon by the suction of the en ine. The chamber 28 communicates with tie bore 5 through a passage 30 and should the valve 17 fail to seat immediately at the end of the suction stroke of the en- 7 gine the surplus water which passes said valve 17 will escape through the passage 30, as the valve 27 will be opened by gravity.

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is here in reserved to make such changes as properly fall within the scope of the appended claims.

Having described the invention, what is claimed .is:

1. An engine attachment comprising a. body having a longitudinal bore extending therefrom and defining an inlet opening at one end and an outlet opening at the opposite end, a needle valve controlling the inlet opening, a suction operated valve spaced from and controlling the outlet opening and a normally open drain valve communicating with the bore between the suction valve and outlet opening and adapted to be closed when the suction valve is opened.

2. An engine attachment comprising a body having a straight horizontally arranged bore at its inlet end and. a similar bore at its outlet end, the last mentioned bore beingvof arelatively higher plane and an inclined bore connecting the inner ends of the inlet and outlet bores, controlling the inlet bore, a spring pressed suction operated valve located within the inclined bore for controlling theoutlet bore and a normal y open valve controlled drain communicating with the outlet bore.

In testimony whereof we aflix our signatures. e
