To allwhom it may concern: *Beit known that I, 1 Claims SINGELYN,

a'citizen of the-United States, residing at Detroit, county-of Wayne, State of M1ch1- gan'yha-ve invented agcertain-new and use- :Eu'l Improvement in Automatic Air-Regulators for Automobile Gas En'gines, and de- I cla'r'e the following to -be'a"'-full', 'clear, and exact description ofthe same, such as w1ll .enable others skilledin the; artto which it pertains to make and use the same,"-reference" whic bein ,:.had to the accompanying drawings; l1 form a part' of this specificatlonl 1 My invention relates' to 1 an improvement r for: gas engines -for 'niotor vehicles f Y The; object r :to: provide means whereby an additionalsupply of'riair :will Be -admitted to the 'gas mixture 'as';th running speed ofi (r W n the? engine increases; .An additional obj ec means whereby the quantity I of; air this a'dmitted- V will ivary :directlyf as 'Zthe': speed-increases and such=addit1onalisupply will be. automatically shuts ofli as the amount of fuel passingthrough vthe intake falls 'be lowzi-aucertainminrmummii an additional obj ecteis aloe-provide inexpensive s imple means connected up w1th=' the throttle rod so that actuation thereof to increase, the duel supply; Wlll automatically furnish an additional air supply to the'e'n-.

gine, the reverse. likewise 'being' true.

In the drawings:

Figure l is a conventional gas engine with my improvement attached.

Fig. 2 is a detail sectional View.

A form of conventional gas engine is represented by a, the gas intake pipe is represented by b, accelerator rod 0 is connected up by means of link d to bell crank e at the lower extremity of the throttle rod. f indicates a plunger guide, having an interior air passageway p which communicates with the atmosphere through air inlet holes 6. Plunger guide f is screwed or otherwlse inserted through the wall of the gas intake pipe, the interior air passageway 39 communicating with the gas intake pipe. Within the plunger guide is disposed a plunger 9 held therein by means of a spring k, so as to normally cover air inlet holes 2'. A flexible linkage is provided connecting said plunger with the accelerator rod. A telescopic link is here shown consisting of a rod is held telescopically within tubular member j. A stop 9 is provided on the plunger, a stop 7' is promada nag-mention FOR v1 XUTILOMOBILE GAS-1i|1 1'GIl\TES.

' videdonthe telescopiclink. When the accelerator rod has been withdrawn su'fiiciently to bring link 7' asit'pivots about its pivotal I point-on plunger g into perpendicular position thereto stop j is brought into cong and further rotation of tact with stop the-link about 'itsipivotalpoint on'the plunger is prevented; Plunger "g is then withdrawn equally with the accelerator rod.

Forexample', let the position m indicate the-throttle valve as closed, The plunger is held'seated in the plunger guide and the 1 air inl'et holes are closed thereby. n would indicate the =positionof'the Llink j up to the time the acceleratorrod had been actuated such d-istance' that it would begin to actuate the plunger and would be adjusted in such a manner a's to provide sufiicient inlet of gas tozth'eg eng1ne"to"attain"-a predetermined engine speedi Passing point n or after this predetermined engine speed h'asbeen passed,

thev plunger :will -be actuated equally with theiaccelerator rod uncovering air inlet holes in proportion to its actuation, thereby admrtting ain, to ithesintake in proportion to' I the! increase of gas fldw thereinzl It will be 7 apparent 'thatithe withdra'wal of the plungerand consequent uncovering of air inletholes in theplungerwill bear a direct ratio to the admissiOn-of-fuehto the engine as regulated by the-operation of thethrottle" rod It will-be observed that rod c'would be actuated by the accelerator pedal the same as through link (1 connecting the same up to the throttle rod. The primary purpose however is to provide means whereby as the flow of fuel to the en ine is increased after the passing of sai minimum rate of flow has been reached, additional air supply would be automatically admitted to the gas mixture proportionate therewith and this would normally be accomplished through the throttle rod.

What I claim is:

1. In a gas engine for motor vehicles, in

combination with the gas inlet pipe a plunger guide having an air passageway leading therein such air passageway communicating with the atmosphere by means of a series of air inlet holes, a plunger disposed in said plunger guide normally closing said air inlet holes, means connecting said plunger with the throttle rod, such means so adapted that after the throttle rod has been actuated a predetermined distance the plunger will commence to withdraw, uncovering the air inlet holes in the plunger guide directproportion to the further actuation of said throttle rod beyond SIIChzPIGdGtQIIDiHGd'diS- tance.

2.
