.To all 'whom t may concern: A

Be it known that I, BRAINARD G. Riou, a citizen of the United Sieges, and a resident of Colville in the county of Stevens and "State of Vlashington, haveg'nvented a new .manifold for/governing the inlet of. aiuto the uel' mixture before entering the cylinder toregu1ate the character of the mixture l under given conditions requiring the richneof the mixture to be varied.

An object ofthe invention is to'provide an ajuxillary ain-valve, and. automatic ccntrolling means therefor, whereby under-norl mulconditions, when" the automobile is running. on level lground, a regulated,` quantity of air will be supplied to the' intake mani.n fold "and whereby the'l supply of air will be decreased in proportion to the grade of ascent or entirely cut oiupon a lpredetermined grade .being reached; the reverse automatically taking place when the autcmobile is running down grade so that en increased quantity of air will be admitd to reduce' the richness of the mixtureu Important objects of the invention also are toprovide v01' automatic valve control through the medium of a pendulous device; to so connect th endulous device that it will accommodate Aitself to a lateral tilting of the automobile preventing bindin of the valve elemehts, and to provide .or the manual movement of the pendulum for cut? Weather conditions.

tingod the supply of air when starting with the engine cold, or running' under very cold An object of the invention also is to provide a valve of the indicated character having an inlet in the/valve body 0r fixed part and an inlet in the automatically movable -(3o-acting controlling element to be brought more or'less into or out of register with the first inlet; together with manually controlled regulatin means to vary the capacity of the lirst in et.

A more specific object of the invention is to provide 'an auxiliary air valve improved various particulars with reference to simy pli'city of construction and with a View to promote convenience in assembling ,or edjusti'ng the parts. Reference isto'be had to the accomgmnyn ingdrawings forming a part ofthis specifi cation in which similar reference cliaract indicate corresponding parte in'all. the vie it heingunderstcod that thedrawings are i 'merely illustrative of one exemple of the invention.

litigare 1 is a perspective view of an auxillary air valve embodying my invention, showing' the name applied to an intake maf-ii fold;

Fig. is a longitudinal 'vertical section of the vaive;

Fig. 3 a@ transverse said valve;

Fig. 4 detail in transverse vertical section indicating tbe preferred manner of operating the pull cord manually controlling the endulum.

y improved air valve is vertical "section of designed' to be tapped into. an intake manifold A, the per tioula'r location of the valve dependingon the .form of manifold, employed. In the illustrated example the valve is formed and arranged for use where the intake manifold. is on the right hand side of the engine iooking from the drvers seat. Said valve in cludes a tubular body 10 having at the for- Ward 'end thereof suitable means securing it in position, there being shown a threaded nipple et the forward terminal 1l ada ted to engage e tapnedjhole in the meni old there being a poiygcnal iauge 12 at the base' of the nipple 1l adapted to receive a Wrench.. The valve body 10 1s rcvided with an inlet orifice to be contro led, the said inlet in the presentinstance being in the side of the valve body and indice-ted. by thenumeral 13. A sleeve 14 is loose on the body 10 and is adapted by turning movement in opposite' directions to control the inlet 13. AIn the present arrangement the sleevel is formed with an inlet port 15 adapted tobe brought' more or less into or out of re ter'wth the inlet 13 or to entirely' cut oli t e latter. The

'Sil

sleeve 14 is held in position between the flange 12 and a set colla 16, the numeral 17 indicating the set screw of the collar.

To automatcall' turnighe sleeve 14 in opposite directions orhregulating the ow of air through the valve body I provide' s. pendulum designated generally by the 'neri 18, which Ahas suspending arms ienne-.i

lill

with eyes or equivalent formations at the upper end thereof to hang the arms on 1ateral pins 21 at diametrieallyY `opposite sides of the sleeve 14.

By the described arrangement it will be clear that oscillations of the pendulum in its own plane, that is to say, in a plane transverse to the axis of the`valve, will turn the sleeve 14. Thus, the inlet 15 will partially register with the inlet 13 to allow a limited quantity of air to flow through the valve as when running under normal weather conditions on a level road. Upon the automobile aseendin a grade the pendulum will swing rearwar l', thereby turning the sleeve 14 forwardly to gradually reduce the effective area of the inlet or to finally close the inlet upon a redetermined grade having been reached` n the other hand upon t 1e au toniobile reaching a down grade the pendulum will swing in the opposite direction in creasing the area of the inlet to cause an increased Vdilution of the fuel mixture.

" The forward swinging of the pendulum 18 is limited by a stop 22 which in the illustrated example is in the form of a wire or bent rod fixed at -on`e end on the valve body',

`onthe ange 12, or other convenient part of the valve body and extends into the path of movement of the forward suspension arm 19 ofthe pendulum.

To manually swing the pendulum to close the air inlet for starting, or under other con ditions requiring the full richness of the fuel mixture, I connect a string, 23, cord, or the like, at one end with the-pendulum as at 24 and extend the cord or the like to the dash B- or other place for convenient operahaving an operating rod 25 thereon slidabloI in a bushing 26 in the dash, said rod having a handle 27 at its rear end Yat one side of the dash, and a collar 28 or equivalent stop elonient adapted to Contact with the front side of the dash for limiting the pull on the cord.

It will be observed that the eyes of the sleeves 2O are loose on the pins 21 and by reason of this arrangement when the automobile tilts laterally the pendulum may swing outwardly or inwardly transverse to its ordinary plane of oscillation and without imparting any turning movement to the sleeve 14, to prevent the lateral swinging of the pendulum from binding the sleeve on the valve art. A

I Wlsh to State in conclusion that although the illustrated example constitutes a practical embodiment `of my invention, I do not limit myself strictly to the mechanical details hereinx illustrated, since manifestly the same'can be considerably varied without departure from the sprit of the invention as defined in the appended claim.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent: Y

An air valve including a valve body, a sleeve loose on the valve body and controlling, by a turning movement, the flow of air througlaFthe valve body, and a- -pendulum hung on the sleeve, the said sleevebeing operated by the oscillations of the pendulum in one plane, and said pendulum being adapted to swing at right angles to the rst plane independently of the sleeve.
