To all whom it may concern:

Be it known that I, HOMER E. BARNT- HOUSE, a citizen of the United States, residing at Marion, in the county of Marion, State of Ohio, have invented a new and useful Auxiliary Valve for Internal-Combustion Engines; and I do hereby 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 the art of valves and the like, and more particularly to a new and useful valve especially adapted for internal combustion engines for supplying additional air to the intake manifold to mix with the charge passing therethrough.

Another object of the invention is the provision of means for regulating the amount of additional air.

.Another object of the invention is to dispose the. valve operating handle in such position as to prevent the same from being in the way.

One of the features of the invention is the provision of a member threaded into the intake of the valve and provided with oppositely disposed yieldable parts or prongs, whereby, as the member is adjusted into and out of the inlet of the valve, said opposing prongs will move toward and from each other to regulate the amount of additional air.

In practical fields. the details of'construction may necessitate alterations falling within the scope of what is claimed.

The invention comprises further featuresand combination of parts, as hereinafter set forth, shown in the drawings and claimed. 7

In the drawings: 1

Fig. 2 is a plan view of the same.

v Fig. 3 is asectional view on line '3-3 of Fig. 1.

Fig. 4 is a view in side elevation ,of an intake manifold, showing another form of a valve and operating means applied.

Fig. 7 is a longitudinal sectional view through the handle extension part of the valve operating means.

Fig. 8 is a detail perspective view of the member for regulating the amount of the additional air.

Fig. 9 is a sectional view on line 9-9 of Fig. 6.

Referring more especially to the drawings, l designates an intake manifold of an internal combustion automobile engine, and 2 denotes an auxiliary valve casing. The valve casing 2 has a threaded extension 3, which is threaded into the wall of the manifold, as shown. The valve casing is provided with an intake passage 4, through which an auxiliary supply of air may pass, in order to enter the intake manifold. Formed in the casing 2 and at right angles to the passage 4 is a conical opening 5. for the reception of the tapering plug valve 6, on to an extension 7 of which. a suitable washer Sis fitted. A screw 9 is threaded into the smaller end of the plug valve, and interposed between the head, of the screw 9 and sa d washer 8, is a plate 10, thereby holding the washer 8 closely in engagement with the valve casing. By setting up on the screw 9, the plug valve 6 may be tightened in its opening 5. The tapering plug valve is provided with a transverse opening 11, which may register with the passage 4, whereby an extra supply of air may pass therethrough and into the intake manifold. The valve casing 2 is provided with a chamber 12 adjacent that portion of the passage 4- nearest the intake manifold, and into th s chamber 12, this additional air may collect. As the opening 11 begins to gradually register with the chamber 12. as the valve- 6 is opened or gradually adjusted toward an open position. the additional air gradually increases. and when the valve 6 is gradually. closed, the additional air is gradually decreased. By means of this additional air into the intake manifold. the charge from the carbureter to the engine is additionally volatilized or vaporized, and under these conditions the carbureter requires less fuel. The larger end of the valve is provided with an extension 13 terminating in a flat part 14. through an aperture 15 of which, the angled end 16 of the valve operating rod 17 is disposed, there being a cotter pin 18, to hold the angled end in place. The other end of the rod 17 terminates in a handle 19. By turning the rod 17 in one direction or the other, the tapered plug valve 6 may be rotated in one direction or the other to cause the opening 11 to register with the chamber 12 and one end portion of the passage 4, so'that an additional iupdply of air may enter the intake mani- In Figs. 4, 5 and 6, the valve casing 2 has its extension 20 interiorly threaded, as shown at 21, and which threaded interior is larger in diameter than the passage 4. Engaging the threads of the interior 21 is a plug or member 22, which is provided with oppositely disposed yieldable prongs 23. The outer faces of the prongs 23 are so inclined as to cooperate with diametrically opposite sides of the passage 4, as shown at 24, ad jacent the shoulder 25, in order to cause the prongs to move toward and from each other, whereby the additional supply of air may be decreased or increased. In other words, when the valve 6 is adjusted, whereby the maximum supply of additional air is admitted, the plug or member 22 may be adjusted, so that the prongs or members 23 will move toward and from each other, in order to regulate the maximum supply of air. The plug or member 22 is provided with a pair of diametrically opposite projections 26, to be engaged by a spanner wrench, whereby the plug or member 22 may be adjusted. In Figs. 4 and 7, the valve operating rod consists of two sections, a.

valve engaging section 27 and a tubular handle section 28, which telescopically receives the section 27. A spring blade 29 is secured by a screw 30 to the tubular handle section- 28, and extending from the blade 29 is a lug 31 passing through an opening 32 in the wall of the tubular handle section.

This lug 31 enters an elongated groove 33' the valve, in order to hold the handle section out of the way.

ing in an enlarged chamber adjacent the tapering opening, the passage of the other extension having its outer end portion enlarged which is interiorly threaded and provided with an interior annular shoulder, a tubular bushing member adjustably threaded into the enlargement of the passage of the second extension, one end of said bushing member being conical said conical portion being bifurcated substantially its full length, thereby causing to be formed opposite yieldable prongs extending into the small part of the passage last mentioned, the outer curved portions of the prongs being adapted to contact with the smaller part of said passage, whereby, as the bushing member is adjusted, said prongs may be moved toward or from each other for regulating an extra supply of air said enlarged portion of said passage adjacent said shoulders acting as a chamber for the collection of the air as it passes through the bushing member, the bushing member at its outer end having means to be engaged by an operating device for adjusting the bushing member, a tapered plug valve in'said tapered opening and provided with a transverse opening; to cooperate with said axially alined passages to additionally regulate a supply of air, and adjustable means for operating the tapered plug valve.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

HOMER E. BARNTHOUSE.
