AUTOMIQIIG AIR CONTROL.

Specification of Letters Patent.

Application filed March 3, 1917. Serial No. 152,291. Y

To all whom itvmay concern:

Be it known that I, ULYSSES S. GRANT HINTON, a citizen of the United States, residing at Monterey Park, in the county of Los Angeles, State of California, have invented new and useful Improvements in Automatic Air Control, of which the follow- 'ing is a specification;

This invention relates to gas savers for automobiles and the like; and it is an object of this invention to provide a simple and inexpensive device which may be easily applied to a carbureter and which, when ap plied, has the function of greatly increasing the ,efiiciency of the carbureter and the engine to which it is attached.

It is further an object of this invention to provide a device which, when applied to a carbureter, will always be uniform in action and will not be affected in action by variations in the sizeof the parts in which it is placed. For instance, in some gas savers, the application of the saver to the carbureter is liable to change the interrelation of the parts of the gas saver, so that the gas saver does not act in a normal and uniform manner; and it is a specific objectof my invention to overcome this difliculty.

It is also an object of my invention to pro-- vide, in such a simple device as herein described, a means for taking care of back fires through the carbureter. This I do in a very simple manner, as hereinafter specified.

In the following specifications, I describe a preferred and specific form of device embodying my invention; and reference is had for this purpose to the accompanying drawings in which Figure 1 is a side elevation of a carbureter, showing my gas saver in operative position, certain parts being shown in section; Fig. 2 is an enlarged longitudinal section of mygas saver; Fig. 3 is an end view thereof taken as indicated by line 8-3 on Fig. 2; and Fig. 4 is a section taken as indicated by line 4.4 on-Fig. 2. v

In the drawings the numeral 10 designates any ordinary carbureter having its air intake at 11, which maybe controlled by air throttle 12. In one common form of carbureter this air intake may be provided with a tube 13, which extends outwardly and upwardly,having a part 14 at its upper end 7 adapted to be clamped against the exhaust manifold of the engine, for the purpose of heating the air entering the carburetef. I

make my gas saver 15 to fit .into the inner end of this tube 13. My gas saver comprises a cylindrical shell 16 with a prefer-- ably conical enlargement 16? on one end.

This enlargement is of. such dimensions as to cause the shellto befitted tightlyiand snugly intoany tube 13, taking'c'are' of any small variations in the size of thetu be; and doing this without the necessity of changing the effective diameter of the shell 16. In the other end of the shell I mountthe pivoted valve 17. This valve 17 is pivotally mounted upon a suitable transverse plvot pin 18, ears 19 being turned upon the periphery of the valve to engage the pivot pin 18. Pivot pin 18 is s et'in shelll16 by providing indentations in the wall of the shell, as shown at 20, and passing the'pivot pin through apertures in the indented portions.

Valve 17 is preferably made of stamped I sheet metal and is substantially circular; and has a hook 21 stamped out of itself'and adapted to be engaged by the end of the valve closing spring 22, the other end of the valve closing spring hooked around a small projection 23 at the swedged end of the shell. The valve normally stands in the position shown in the drawings; and its upper edge presses against a stop 24 formed by the inwardbending of a small portion of the endof the shell; the spring 22 holding the Valve normallyagainst this stop. The lower part of the valizefbeing that-part below the pivot pin 18, isbent outwardly, as shown at 17 in Fig.2, so that this part stands in a diagonal position point- 7 ing diagonally outward toward the direction from which the air comes, this direction being indicated by the arrow in Fig. 2. Any back fire which occurs comes from the direction of the carbureter, and impinges upon the valve in the direction opposite to'that indicated ,on Fig.2. v i v,

It will be noted .that the shell and the valve being both circular, there is a2 definite and uniform open space ;-around thejupper part of the valve, between the upperpart of the valve and the shell"; but the bending of the lower part 17 of the valve, to adiago'nal position, makes a somewhat 'wider opening a e s le e rar we engage shell; that is, between the shell and that part of the valve which is below the pivot pin 18. By reference to the drawings, it will be seen that the space at 25 is Wider than the space at 26. This widened space, and the diagonal position of the parts 17*, play an important function; and it will he noted that,

for the purpose of this function, it is important that the relation of the valve to the shell be fixed and not be variable. the engine is running at low speed, sufiicient air is drawn through the spaces around the valve to supply the engine; when the engine runs at a higher speed, or the throttle is opened to admit more air to the engine, then the valve is proportionately opened against the action of spring 22; the strength and tension of this spring being determined and Y set-in accordance with the requirements of the carbureter and engine. Now, when a back fire occurs, the back rush of gases tends to immediately seek the path of least resistance to flow; and the stream of outrushing gases is thus directed to the wider opening at 25 under the diagonal part 17*. The effect of this construction and'operation has been shown in practice to sufliciently relieve J the back pressure.

The moving parts are preferably of light weight, so as to respond quickly, and I find that my gas saver is not only very etficlent in action, due to the fact of proper proportioning and unchangeable relation between the shell and the valve; but is also very etfective to release a back fire, due to the action just described.

. Having described a preferred form of my invention, I claim:

1. A gas saver for a carbureter adapted to be attached to the air intake of the carbureter; embodying an exterior shell, a valve I. pivoted transversely across the shell and 7 bearing a certain definite and unchangeable bureter; embodying an exterior shell, a valve 1 pivoted transversely across the shell and bearinga certain definite and unchangeable relation to the shell, and spring means to normally hold said valveclosed. the body of said valve extending substantially transversely across the shell, and a part of said valve on-one side of its pivot, extending di- 4 agonallv outwardly toward the outer end of the shell. there being a fixed open space between the body of the valve and the shell, and there being a widerrfixed open space When between the diagonally extending portion of the valve and the shell, whereby back fire pressure is relieved.

3. A gas saver for a carbureter adapted to be attached to the air intake of the carbureter comprising an attaching member; an exterior shell adapted to be inserted into the attaching member, a valve pivoted transversely across the shell and bearing a certain definite and unchangeable relation to the shell, and spring means to normally hold said valve closed, the shell having means formed at the end adapted to retain the shell in the attaching member subsequent to insertion therein without changing the definite relation of the shell to the valve.

4. A gas saver for a carbureter adapted to be attached to the air intake of the carbureter; embodying an exterior shell, a valve pivoted transversely across the shell and 85 hearing a certain definite and unchangeable relation to the shell, and spring means to normally hold said valve closed. the body of said valve extending substantially transversely across the shell, and a part of said valve on one side of its pivot, extendingdi agonally outwardly toward the outer end of the shell, there being a fixed open space between the body of the valve and the shell, and there being a wider fixed open space between the diagonally extending portion of the valve and the shell whereby back-fire pressure is relieved, the shell having an enlarged end for fitting the shell into the'air intake without changing the definite relation of the shell to the valve.

5. A gas saver for a carbureter adapted to be attached to the air intake of the carbureter; embodying an exterior shell. a valve pivoted transversely across the shell, and

spring means to normally hold said valve in closed positionacross the shell. the body of 7 said valve extending substantially transversely across the shell. and having an opening movement inwardly against the action of saidspring, and a part of said valve on one side of its pivot extending diagonally outwardly toward the outer end of the shell and spaced from the shell, whereby back fire pressure is relieved.
