VAppncanw filed July 2s, 1921. serial no. 425,225. i

'- invention relates tomake and use the same,

reference being made therein to /theaccompanying drawings, which form a partof this specification. f Y

"llhe inventionrelates Vto valve mechanism,

and while-in some .respects'of more general applicatiom'it has Vbeen. designed with particular rreference to use in Vconnection with an air heater of the typeue'mployed'in sup'-V plying heated "air to fav carbureter of an internal combustion eng-ine.V l

The 'nventionrhas for it-sf principal object the provision' of yan improved Y valve mechanism capable ofV being easily and.

-, improved handle and locking `device whereb14 i suitable-bending cheaply manufactured and assembled and y being leasy, of j adjustment and eflicient in? operation. l n Y j A further'object is the provision of a valve structure comprising -in a single `piece a valve member proper-anda `spindle or shaft ltherefor, the 4whole being'formed by sheet metal blanl.` A

vA Vfurther object is tliev-provision" of an the valve spindle may be rotatedV and 'whereby itmaybe retained.inthexdesired positionsofadjustment.- 1

Further objectsand advantages will appear from the following descriptiontakeir in connection with the accompanying drawings, in which- Fig. 1 is a side elevation of an internal combustion engine showing in connection therewith one embodiment of my invention; Fig. 2 is a cross section on line 2-2 of Fig. 1;

Fig. 3 is an elevation of the air conduit shown in Fig. ltaken from the right end;

Fig. 4 is a plan view and Fig. 5 an end elevation of the valve member;

Fig. 6 is a plan view of the blank from which the valve member is formed; and

Fig. 7 is a plan view of the combined handle and locking device applied to a slightly different form of valve member.l

operations from a Vunitary Referring to the drawings, 10 indicates an internal combustion engine includlngV the intake manifold 11, an exhaust manifold V12, and carbureter 13. A heating device,

ordinarily termed a stove, is provided for heating the air supplied to the carbureter intake 14which stove may comprise,v asY shown, a. jacket or belll surroundingy a part of theexhaust manifold and connected by a branched conduit 16 to the air intake '14, one branch of the conduit opening directly to the air, as at 17 .i A valve .member of suitable form, as the butterfly valve 18, is pivotally mounted, as at 19, in suchposition thatrbyrotation or oscillation of the valve 1 it maybeposition'ed either to' close the opening of the conduit 17 or the branch leading to, theheating jacket 15. The valve therefore provides a meanswhereby heated air may be supplied to the carbureter or the air may be taken directly from the exterior lwithout preheating.y

The valvemechanism with which invention is more directlyconcerned comprises a valve memberzproper as shown at Y18` and a spindle or shaft therefor Aindicated at 20. I form the valve preferably by bending `operations from a sheet metal blank of the form illustrated in Fig. 6 comprisinga shaft portion 20 of suitable dimensions to ,pro`v-ide,`when bent to tubular form, thespin'dle20 and an extension-18 of suitable foijm to close thepassage with whichV the valve may be associated. Y It will be noted that the shaft ,portion 20 has projecting portions extending in-both directions be- -yondgthe portion 18', as aty 21', 22',v which extensions, `when the shaft ortion is bent to tubular form, serve as journals 21, 22 adapted to seat within vsuitable apertures inV the walls of ak conduit to provide pivotal support for the valve member.

In order to rotate the valve, I provide a handle 23 formed preferably from resilient material, as from spring wire. One end of the handle may be formedv with a loop V24g having a hooked end 25, the other end being provided with aV suitably shaped portion, asa loop 26, whereby the handle may be seized and the valve rotated to the desired positions of adjustment. A slot 27 is provided in one side of the journal portion `22 throughwhich the handle 23 may be journal 22 with the hook 25 engaging the end of the slot to thereby` prevent displacement of the handle. An aperture 28 is formed in the 'journal portion 22 opposite the slot 27, which aperture maybe con-` stitutedby two notches 28 in the mating edges of the blank portion 22 and through which aperture the handle 23`extends. The handle will be made preferably of such length as to extend outwardly over the curved surface of the conduit with which the valve is associatedv and will be bent in suc-h manner as to contact resilientlywith such conduit. The frictional engagement of the handle with the walls of the conduit will therefore tend to retain the valve in the desired positions of adjustment, particularly if, as illustrated in Fig. l, the shape of theconduit is such that the tendency of the handle to slide downwardly over the curved surface of theconduit will cause the valve member tov move toward its. closed position at the respective extremesof its movement. l By merely grasping the loop 26,

however, the handle may be readily bent away7 from the seated position against the conduit and the valve may then be rotated to theV opposite eXtreme of its movement, where it will be resiliently reta-ined upon releasing the handle. l

lli/'here a valve of the form illustrated in Fig. 7 is employed, comprising a valve member 29"secured to a spindle 30 as by screws 31,'the spring handle 23 may be attachedV tothe spindle by ,the provision of a loop 2li lying in a plane at right angles to the plane of the loop 26 and secured to the spindle 30 as by clamping it between the nuts 31. The operation in this case will'be the same as that already described, in that the resilient portion of the handle 23 enn gaging the walls of the conduit with which the valve is associatedwilltendto retain the valve resiliently" in yitsy exteremeV posi.- tions. v

Various other changes may be made k,in details of construction and operation without departing from ythe spirit and scope of the invention and therefore l do not wish tov be. limited to the specific strueture herein set forth except as required by the language of the appended claims in view of the prior art. Y i

Y'I claim: Y

i. In valve mechanism, the combination of a conduit having curved walls, a valve therein having two, eXtreme positions of adjustment, and a resilient handle for said valve shaped to engage said curved Walls and thereby retain the valve in either of its positions.

2. In valve mechanism, the combination of a branched conduit, a valve pivoted in said conduit in position toclose either of itsbranches, a handle comprising'aresilient wire connected to said valve, said handle shaped to engage opposite sides of said conduit when the valve is in its Arespective positions and adapted, by engagement with the conduit, to force the valve resiliently to its extreme positions.

3,. Invalve mechanism, the combination with a valve member comprising a flowobstructing portion anda spindlel portion formed from a Vsingle piece of sheet material, said spindle portion havingapertures therethrough, of a handlemember comprising a resilient device seated in said apertures.

Ll. rlhe combination with a member to be rotated comprising a spindle formed by bending sheet material into tubular form, said spindle having apertures upon -opposite sides thereof, of a handle comprising a resilient wire bent to form to pass through said apertures and be retained therein.

45. In valve mechanism, a valve member mountedy for pivotal movement aboutone edge thereof, said member comprising a 'body portion and ay shaft portion formed from'a blank of sheet materiahthe shaft portion being constituted by a part, ofy the bla-nk extendngbeyendthe bedr Dertien in the direction1 of the'pivoty and ,bent tov form a spindle. y
