To all whom it may concern:

tie it known that .th trainer i fnornna a.

resident of flincinnati, in the county of ltit Valves for internal-Combustion lEntttt gripes tioni this invention a novel auxiliary a r oit which. the following is a specificaminer or valve by the use ot the which air is admitted between the carburetor and the intalte manifold ot an internal combustion engine to be mixed With the tool tron). the ear-boreteiz The invention includes means ivherehy the air miner Will be set to admit more or less air according; to the position ot the throttle valve and also includes means whereby at higher speeds at the engine a greater volume of air will he ttiitltflltltltlltfttlly admitted and a charge of the proper quality supplied to the engine thus incriasinp; the

power and speed ot the engine and. econoncliting tiiel.

tine embodiment ot the invention, is illustrated in the accompanying drawiinr, in

which? lt ha"; l is an elevation ot a carbnreter and a part of the trunk of an intake manit'old having my auxiliary device eon'ibined therewith,

hip; 52/ is a side view ot my device With parts in section on. the line of Fig". 1,

his". 3 is a view similar to high 2 but viewing; the opposite side ot the device, and

Fig. t is a section on the line t tet l itg'.

'llhe carbureter 1 may he of any Welt leaovvn or preferred type and is controlled by a'throttle valve? actuated by a lever 3 which is connected With a throttle rod t. 'lhe tuel passing}: from the carburetor is delivered into the trunli: ot the intake manifold and thence flows into the engine cylinders. in carrying oatv my invention,

ll. inter-pose between t e carbureter' outlet and the trunk 5 a flat body 6 havin an opening; 7 through its upper portion adaptand the carburetor outlet and of the same diameter so that a continuous passage for the flow oi the gas Will be provided. The body 6 is provided on opposite sides With lateral Wings 8 through which and logs 9 on the carburetor and the manifold trunk securing l; olts are inserted to firmly eonnect the parts suitable packing being" provided between the opposed surfaces to prevent leakage. lining ring 10 is fitted in the opening 7 and secured in place in any convenient manner, said lining ring being constructed with two series of openings or perforations or ports i1 and 12 Which regrater respectively with the grooves or passages 13 and it termed in the body 6 around the opening 7, the ports restricting the communication between said grooves and the bore or opening 7, and the perforations or ports 11 being smaller in diameter than the perto 'ations 12. The passages 13 and it are carried into a depending extension 15 at the body it where they merge into the Walls of chambers 16 and 17 respectively said chambers being: separated by a ported partition i8 rind, the (llttll'llJBI 16 commnnicat with the outside air througl'i a port 19 in the side oi" he body, An opening 20 is provided in the side of the chamber 17 to permit the insertion of a disk valve 21 and a spring 22 for holding said valve normally seated in the portot the partition 18. After the valve and springs-re in place, as shown in Fig. i, the opening 20 is covered by a cap plate 23 which is rigidly secured upon the side of the extension 15.

Upon the outer side of the capplate #23 is a tubular body 24; in which is housed one end of a coiled spring 25, the outer end at said spring being; attached to or beariitrr upon one end oi a bent lever 26 which is 'fulcrurned between lugs 27 on the extension ed to register with the harm of the trunltnear its lower end between the same 'lihe tit lower end of the trip lever bears upon the outer edge oi the lever 26 and presents a convex edge thereto, as shown at 32, while the upper longer arm of the trip lever is disposed adjacent and in the path of a trigger 33 secured upon the throttle rod 4. It is thought the operation will be readily understood. The parts are illustrated in the position assumed when the engine is running idle. As the throttle is opened for more speed. the trigger 33 is caused to impinge upon the trip lever 31 and swing the upper end thereof outwardly or away from the body of the device. The lower end of the said lever will be thereby caused to rock the angle lever 26 against the tension of the spring 25 so that the valve 28 will be opened. thereby admitting air to the chamber 16. This air will at once flow through the groove 13 and escape through the ports or openings 11, which are appreci ably smaller than the openings 12, in small streams of high velocity which will penetrate the mixture flowing from the carbureter. As the engine speed increases. the air pressure will. eventually overcome the force of the spring 22 and unseat the valve 21 whereupon air will flow through the groove l t to and through the ports .12 to penetrate the charge. As the engine speed decreases, the valve 21 will be seated but the valve.28 will remain open until the throttle rod 4 is shifted sufliciently to permititto close.

It will be readily noted thatI have provided a verv simple and eificient device. By its use, mileage per gallon of fuel is increased and the engine will run more smoothly and With greater speed and power than heretofore. The device acts as a mixer by discharging streams of air at high velocity into the mixture supplied by the carburetor and the additional air supply results in greater speed and power. The inner valve 21 is brought into action only after the outer valve 28 is raised, and supplies 'needed additional air as the speed increases.

When the speed drops under a load, as when climbing a hill in an automobile, the valve '21 will. close but the valve 28 will remain open. The throttle may be set for full speed and under an increased load will remain Wide open but air will enter only through the small ports 11.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent of the United States is 1. A- device of the character described adapted to be placed between a carbureter and an internal combustion engine. comprising a body or casing having an opening to register with the outlet of the carbureter, said body having a plurality of passagesto admit air to said opening. a valve for ad mitting air to one of said passages, and

a normally closed automatically actuated valve for admitting air to another of said passages, when the first mentioned valve is opened.

2. A device of the character described adapted to be placed between a carburetor and an internal combustion engine comprising a body or casing having an opening to register with the outlet of the carburetor, said body having a plurality of passages to admit air to said opening, independent valves controlling said passages, one of said valves being controlled by the throttling mechanism of the carbureter and the second valve being operable automatically by air pressure after the first valve is opened.

3.1K device of the character described adapted to be placed between a carburetor and an internal combustion engine comprising a body or casing having an opening to register with the outlet of the carlimreter, said body having a plurality ofrpassages to admit air to said opening, means surrounding said opening provided with a plurality of perforations communicating with said passages, a valve for admitting air to one of said passages and a normally closed automatically actuated valve for admitting air to another of said passages, when the first mentioned valve is opened.

i. A device of the character describi d adapted to be placed between a carbureter and an internal combustion engine comprising a body or casing having an opening to register with the outlet of the carburcter, said body having a plurality of passages to admit air to said opening, means surrounding said opening provided with a plurality of perforations communicating with said passages. the perforations communicating with one of said passages being smaller in diameter than the perforations communicating with the adjacent passage. a valve for admitting air to one of said passages and a normally closed automatically actuated valve for admitting air to another of said said passages. when the first mentioned valve is opened.

5. In a device for the purpose set forth. the combination of a body having an air passage therein. a valve controlling said passage, a lever fulcrumed on the body and carrying said valve at one end, a spring housed upon the body and bearing upon the opposite end of the lever to hold the valve normally closed. and a second lever disposed at an angle to the first-mentioned leverand bearing upon an edge thereof and operable to rock the first-mentioned lever and open the valve.
