AUTOMATIC FEED VALVE FOR OIL STOVES.
Application filed June 4, 1925. Serial No. 34,960.
To all whom it may concern:
Be it known that I, GRADY A. Poss, a citizen of the United States, residing at Augusta, in the county of Richmond and State of Georgia, have invented certain new and useful Improvements in Automatic Feed Valves for Oil Stoves, of which the following is a specification, reference being had to the accompanying drawings.
This invention relates to the valves which are used on oil stoves for the purpose of controlling the feed of oil from the main reservoir or tank into the sub-tank, these valves being such that the main reservoir may be taken off for filling and then when the reservoir is inverted the valve strikes the bottom of the sub-tank and is thereby opened and the oil discharged into the subtank and to the burners.
The general object of the present invention is to provide a feed valve of this character which is so constructed that it will not tend to puncture or wear a hole in the bottom of the sub-tank.
A further object is to so construct this valve that it will catch all trash, dirt or other foreign matter which would otherwise pass from the main jar or tank into the sub-tank.
My invention is illustrated in the accom panying drawing, wherein Figure 1 is a perspective view of a portion of an oil stove showing the main tank and sub-tank usually found in these structures;
Figure 2 is an elevation of the lower portion of the main tank and the sub-tank, the sub-tank being broken away and the discharge nozzle of the main tank being broken away to show the valve structure therein;
Figure 3 is a vertical sectional view through the valve and allied parts.
Referring to this drawing, it will be seen that I have illustrated one end wall of an oil stove, which is designated 10. This end wall carries the brackets 11 upon which the sub-tank 12 rests and from which a feed pipe 13 extends to the burners (not shown). Adapted to rest upon the sub-tank is the main tank or reservoir 14 which ordinarily is made of glass and is formed with a con tracted neck 15 screw-threaded for the reception of a cap, which cap carries the usual valve. This tank 14 is so mounted upon the stove that it may be swung either into an inverted position or swung to a position with the neck upward, and when in this position the tank 14 may be removed for filling. This construction is commonly found in oil stoves and needs no particular description, as my invention does not relate to any particular means for mounting the tank 14.
The neck 15 is screw-threaded, as before remarked, and engaging the screw-threads of this neck is the cap 16 which is made of thin metal and is provided with a somewhat cylindrical guide 17 having longitudinally extending slots 18. Operating through the central perforation 19 in this cap is the valve rod 20. This valve rod carries the valve 21 and around the valve rod is disposed a coiled compression spring 22, which at its upper end bears against the upper end of the guide 17 and urges downward on the valve 21, thus urging the valve 20 into place on its seat 19. The lower end of the rod 21 carries upon it a cup 23 which, when the tank 14 is inverted upon the sub-tank or bowl 12, bears against the bottom of the sub-tank 12 and causes the valve'2O to 0 en or be lifted against the action of the spring 22, the valve thus remaining open so long as the tank 14 is disposed over the sub-tank 12. Of course, after the usual manner of valves of this character, the valve closes just as soon as the tank 14 is lifted from the sub-tank 12 as, for instance, before filling the tank 14.
It will be seen that the cup 23 rests on the bottom of the sub-tank and the shape of this cup is such as to prevent the valve stem punching a hole in the sub-tank, as it is liable to do where the valve stem is not tilted, as in the present case. By making the shield 23 cupshaped, any trash or dirt which may pass downward as the oil feeds through the valve opening 19 will be caught in this cup and thus prevents this trash and dirt from stopping up the feed pipe.
While I have illustrated a particular form of valve and a particular form of the shield 23, I do not wish to be limited to this as other forms might be used, but I regard the form of the shield as illustrated as preferable for the reasons stated. While I have designed this valve particularly for use with oil stoves or the like, I do not wish to be limited to this as it may be used in many situations.
I claim 1. In an oil burner of the character de scribed, a sub-tank, a main tank invertible upon the sub-tank and having a neck snrrounding an outlet opening, a suqporting member mounted in said neck and having an outlet opening, a valve seating within the outlet opening of the supporting 1ne1nher, a spying" urging said valve 1'0 its seat, the valve having a stem extending beyond the supporting); member and adapted to be engaged by the sub-tank when the main tank is inverted lhei'ein to thereby open the valve, and a shield carried upon the lower exlieznity of the valve stein said shield being "in the form 0'! a one having; an area approxinmt-ely equal to that" of the outlet opening 0]? he main tank in thereby receive oil flowing from said outlet opening and detain foreign matter eenlained within the oil.
2. As an article 0f manufacture, a. valve structure COl'Dp-lls'll'lg a cap having a screwtln'eaded flange and a central outlet aperture, a valve stem passing through said aperin-e end carrying a valve adapted to seat lhereagains; the cap having a guide through which the valve Sl'QlTl passes, a spring surrounding the valve stem hearing against said valve and against said cap to thereby urge the valve to its seat, and a shield c211- iied upon the exterior end ofthe valve stem, said shield being cup-shaped and having a dimnetei' greater than that; of the ordinary outlet epening; with which the valve eoaets.
In testimony ivliei'eolt' I hereunto afiix my signature.
