GGMBINED INTAKE AND DISCHARGE VALVE.

Application filed September 18, 1924. Serial No. 73%,5 25.

Toizll whom it may m Be it known that I, THOMAS BOVEY, a citizen of the United States, and a resident of Chicago, in the county of Cook and State such as will enable others skilled in the art to make and use the same.

. "My present invention relates to a valve for use in conjunction with an automobile heater, the construction of which valve is such that when the valve-plate is in normal position it permits of the continued straight-away flow of the hotv gases from the exhaust maniiold to.the mufiler, but when the valve-plate is moved to a transverse position'for at substantially a rightangle to its normal position, the valve casing will take in hot gas from the exhaust pipe and direct the same to a conduit or pipe leading to the heating radiator within the vehicle, and the same valve and casing will permit the return of the exhaust from the outlet of the heater back into }the exhaust pipe. Thus there is a continuous and uninterrupted 'fiow of the hot gas in which ever position the valve plate may be positioned.

One of the objects of my invention is to provide a valve within which there is provided a web or wall that extends from between the discharge and return stubs into the central portion of the casing'where it turns downwardly to a point about mediate theends of the valve opening or seat at the bottom of the casing so that it will be unnecessary to provide a specially co. structed and positive seat for the valve W 'en in a transverse or open position while the heater is in use.

In my prior application, filed Aprll 5th, 1923, Serial No. 629,987 for a valve for'automobile heaters, I have disclosed a valve of a type similar to the valve herein de-' scribed. In said prior structureit was necessary to form or machine a seat for the edge of the valve-plate so that there'would be a snug fit when the plate is moved to a transverse position in order to prevent the oppositely movingcurrents of hot gas 1n-' terfering with each other. while the heater is in use. This type of structure is expensive from a manufacturin standpoint because it requires the use 0 special tools to mill or machine out an arched seat deep in the casing. I have, in mypresent design of valve, provided a casing in which the web or dividing wall, which provides the inlet and return passageways, extends down to thelocation of the valve-spindle or stein so that it is unnecessary to mill. or machine a seat for the edge of the valve-plate, as before mentioned.

It is a further object of my invention to provide a valve and valve-casing that is simple in construction and dependable in operation and which is novel in the arrangement of its parts. All the foregoing objects I prefer to accomplish in the manner substantially as'hereinafter described and as more particularly pointed out in the appended claims, reference being had to the drawings accompanying this specification Figure 2 is a transverse vertical section 8i? thereof on line 2-2 of Figure 1.

Figure 3 is a central longitudinal section of the structure illustrated in Figure l.

The drawings illustrate a typical or preferred embodiment of my invention, and in $5 said drawings I have designated similar parts by means of the same reference characters wherever said parts occur throughout the several views. The structure preferably" comprises a casting 5 that is hollow, and extending obliquely upwardly from the upper portion of the same is a discharge-stub 6, and disposed with its'axis parailel with the aforesaid stub 6 is a return-stub '3 that leads into the casting for the return of the exhaust gas thereto. These stubs are adapted to recive len the of flexible metallic hose or conduit 0 a length suficient to convey the exhaust gas between valve casing and the proper ports in the radiator of the heater structure that is usually dis posed on the floor of the vehicle. The radiator, the housing therefor, and. -;the flexible pipes, may be of any suitable or well known construction and, therefore, need not be a herein disclosed.

Extending in from the edge of the easing and in a plane betweenthe parallel axes to divide the interior of the latter into two passageways, 9 and 10, one" of which (9) extends directly out of the casting and the other (10) extends parallelthereto and then turns downwardly past the adjacent end of the first passageway so that said passageways terminate alongside .each other at their outer or lower ends. I

The bottom of the casting or housing is provided with a longitudinally eelongated opening 11, which is of substantially the same extent as the combined cross-sectional area of'the two passageways and said open ing 11 is substantially intersected by the adjacent end portion of the wall or web 8.

The casing on its bottom is provided with a: basal member 12 which may be of any suitable shape so as to be conveniently secured to the exhaust conduit or i e that leads from the engine to the mu er. In

the present instance I have shown the basal member arched or concaved upwardly so as to partially surround the cylindrical pipe or embossment and it'is provided with suit-l able means for securing the same" in place. In installing the structure just described a longitudinal elongated aperture l3-is made in the exhaust pipe 1%, of sufiicient width and length to accommodate the movement of the valve-plate, to be-liereinafter de scribed, so that when the arched portion-of the basal member 12 is littedupon the pipe,

14 this aperture l3 will be in registry with the opening 11 formed iiithe casing.

The valve comprises an elongated plate 15 having its ends rounded into semi-circa lar shape so as to snugly fit the aperturell, which is preferably correspondingly shaped in the bottom of the valve casing and said plate is mounted upon a rotatable spindle 16 that-is journaled in the hearings in the opposite side walls of the casing so as to be positioned transversely of the opening at about the lower end of the dividing wall or web 8. A bell crank lever isniounted 'upon one of the extended ends of the'spindle and has its longer arm 1? f of an open. rod extends" into the vehicle to within convenient reach of the occupants. The other or shorter arm 18 0f the bell crank has a coiled contraction 19 connected to it, and the opposite end of said sprin is sccin'ed upon the laterally bent end 20 of rod 21 mounted in a suitable boss 92 formed on exterior wall of the casing. This spr g normally maintains the valve in a closed seat in the aperture ll of the 131 When, however the valve is opened by a longitudinal movement of the rod ill the plate 15 will be moved with its spindle 16 to a position transverse of the opening or aperture ii and with its upper portionalongside the lateral port-ion or" well or'web 8 while its lower portion extend nn'ected to one end position upon its me ial through the aperture 13 in the exhaust ipe to interlit with the lower half thereo so as to interrupt the continuous straight-away fiowor" the exhaust gas. -This will dlrect said gas up into the valve casing and into which returns it to the exhaust pipe 14 through passageway 9 uponfthe opposite side of the valve plate, as indicated by ar rows in Figure 3 ofthe drawings.

What I claim is V 1, A valve comprising acasing havmgan opening in its bottom, two stubs projectmg from said casin a. wall dividing the interior of said casing, into two passageways that communicate with said stubs, said wall extending vto the opening in the bottom of said, casing to CllVldBSiLld opening, means for securing said casing upon -a. chamberv with the opening in registry with an open- 'ing in said chamber, and a valve plate pivotally mounted in-said casing and movable into one position to close the opening therein and into a transverse position to be dis-- posed transversely through said opening and the opening in said chamber.
