Beit known that il, RALPH `Heirs Asiinii,

a citizen ofthe UnitedStates, yand a resident of London, in thecounty of Madison and State of Ohi`o,ih'ave invented a new and I useful `linpfroveineiit in-` Air "Regulators, of

4An object'of my inventionis to provide a 'devicewhioh will'automatically regulate or control the amount ofv air 4entering they carburetor,`in such anianner that the fuel whichis consumed `by aninternal combustion engine, operated in connection with the carburetor, is considerably 'lessthan where sucligair regulation is not used. y i f A further Aobject of my invention is to `provide an air regulator of the Vtype de-` scribed, which'is made inthe form of an unit that may be" inserted in the air' intakepipe leading to the carburetor, without the neces sity of changing or altering either the pipe or the'carbureto'r.

My invention is illustrated in the accompanying drawings, Vforming part of this application, in which-` Fig. l is a side view of a carburetor and an intake pipe leading thereto, the position of the air regulator being shown in dotted.

lines,

' Fig. 2 is a plan `view of the air regulator,

' 'Fig 3 is a sectional view through a por` tion of the air intake pipe, the carburetor connection, and the air regulator, and

Fig. 4 is an end view of the air regulator.`

ln the drawings,y the air intake pipe is indicated at 5this being provided with an the exhaust pipe?, as in the ordinary Ford engine, for the purpose of heating the `in-\ 'opening nppiieanon ined January e, i921. senai no. 434,566.

coming'air. The carburetor 8 isrprovided with the usual pipe connection `9 adapted .to receivethebent end of the intake `pipe 5. The airregulator is made in the form of llt' consists of a short tube 'l0 havi a unit.`

ing a lateral ,eiiteiidingend flange 1l, fthe` widthof this `flange being substantially i thatof the thickness of'thewall of the intake pipe'5,`as'shown in Fig. Theopposite end of the tube is-beveledandfis provided with an inclined end portion 12, which has anopenin'g 13 therein.

purpose explainedy hereinafter.,l Ears 16 eX- p The top portion of the tube 10 has arecess l5 for a tend forwardlyfroni'the beveled end of the tube lOand between these ears is `thepivot pin 17 of a weightedvalveilSL This valve *i is made preferably in theshapeshown in thedrawings and is provided with aflat face arranged to abut the inner side of the end portion 12 so as to normallyclose the lead orwofanyv suitable material.

:ein the `'foregoing' "description `of the vvarieus parte of the device, the'` operationy thereof may be readily understood.y pll'n Figf 'rires-l and 3 3the'valve is shown closed. lt

will be observed that there isa passageway r for lair through"theopening l5 and between rthe upper surface of the valve `l2 on the inner wall of the intakepipe 5.` Vhen the` engine is cranked, air will enter through vthe opening lfandwillvpasson to the carburetor, inixingwith thefuel and being drawn into the cylinders of the engine.` Assoon y 3. Jillhe valve may ybe made of! r as the engine starts," the suction of the en-v Qiiiewill cause the valve l2 to `move away from its seatgthus uncovering the opening 13. The greater the sneed of the engine, thev farther the valve will move, thus allowing vincre air to enter. l have'found'byexperiinentthat thisair control device actually saves a considerable amount of fuel in an internal combustion engine, `such as the Thus, whenan engine with-` out my improved air regulator' is throttled down to a given point, the engine will stop,` whereas under the sanie conditions, with` Ford engine.

'my air regulator, it will continue to'run.

`,f-igai'iii, I havefound thatwith my air reg` ,ulatoig the engine will start, where it will `not start under the, same conditions withy out the air regulator. When iny regulator isy used the needle valve of thecarburetor may `be turned to a point which will more nearly close off thefloW 'Qf ,fuel than is possible,`
