SELF-REGULATING VALVE.

Application filed January It is only when the heater is tilted, the

burner is lowered, or the oil tank raised that this self-regulating valve is brought into action. Innormal operation, the heater is intended tobe level, and rest firmly on the floor.

In the accompanying drawings:

Fig. 1 is a side view with parts broken away;

Fig. 2 is a plan;

Fig. 3 is a view looking down on the weight;

Fig. 4 is a transverse vertical section 5 through the upper end of the device;

Fig. 5 is a view of the bracket;-

Fig. 6 is a view of the connecting-arm;

Fig. 7 is a bottom plan view of the dial; and

Fig. 8 is a top view of the same. I

A valve 11 isinterposed between the sections of-the feed-pipe, the ends of which are this valve is an upright pipe 7 of sufiicient length to support the operating mechanism of the device. This mechanism consists of a weight 6 supported by a rod 5, which is screwed into the upper end of the weight, and also the connecting-arm 2. This connecting-arm is provided with knife or scale bearings 0, which in turn are supported by bracket 1 screwed to the upper end of the upright pipe 7. The lugs on the weight 6 straddle the pipe 7, and are to prevent the weight from being accidentally swung to Screwed into 21, 1925. Serial No. 3,887.

by the use of the knife or scale bearings 0 and 0. The flanged bushing 4 is screwed into the dial from beneath, and set so that there is just a little" play between the bushing and the ball point on the knife-bearings 0, as at X. This serves tokeep the knife bearing'O in place, and to action to the valve stem.

After a hrooder equipped with this selfacting valve has been put into-operation, if the floor should warp from moisture, and raise the oil-container (not shown), an increiase in oil pressure at the valve would resu t. ever, the angle of the pipe7 changes, causing the weight 6 to swing away from the upright pipe 7 .to close partly the valve 11, and to take care of increased oilpressure.

In case the burner is raised, oil pressure is reduced and by the weight swinging toward the upright pipe 7, the valve will open and allow more oil to flow to the burner. If the burner is raised so far that the valve is opened, wide,there would be no danger of flooding, as the oil groove of the burner would be above the oil level in the oil container, and the flame would go out.

A knob with pointer 8 secured on the upper end of the valve stem 9 is provided for the adjustment of the valve.

My improved valve may be adjusted like any ordinary globe or needle-valve'by'turning thispointer 8 quite independently of the compensating and self-adjusting feature, as will be readily understood, as in this way the normal relation of the needle-valve 9 to its seat in the valve 11 is accurately adjusted. his only when the heater is tilted, the burner lowered, or the oil tank raised that the self-adjusting feature is brought into action. In normal operation, the heater is intended to be level and rest firmly on the floor, andthe oil flow to the burner is controlled by means of the needle-valve 9 through adjusting-knob 8. But in case the floor should spring or warp, which apparently happens all too often, as is evidenced by the number of fires reported, the self-adjusting mechanism will control the valve-stem 9, closing the valve in direct proportion to the distance the oil-container may be raised or the burner lowered out of normal, so that the flow of oil, that is the quantity delivered to the burner, will re. main approximately uniform. r

The weight 6 on the rod 5 swings llke a give a: positive As the oil container is raised, howr: in

pendulum and acts on the needle-valve 9 through the arm 2. Scale beam bearings O and 0 are used throughout, thus reducing friction to a minimum.

Thus it will be seen that my improved valve automatically controls the amount of oil delivered to the burner, and as a consequence, it also controls the flame. words, this improved valve will automatically maintain the same size of flame, whether the burner is lowered or the oil containeris'raised, an inch or more from normal operating level. As-xthe'burner is lower.ed,'or the.oil container'is raised, the valve will actin direct proportion to the distance the oilcontainer is raised or the burner is lowered. Extinguishing the-flame is only intended as a last resort, and only takes place after the burner is lowered or oil container is raised far enough to close. the needle-valve.

The length of the arm'2 and taper of the needle-point or valve will determine how far the burner can drop before the valve is fully closed. To those unfamiliar with conditions encountered in brooder-houses, such as warping of the floor boards and the springiness of the floor, which is often the case, the advantages of my improved compensating valve cannot be fullyyappreciated. For example, when adjusting the flamethe weight of :the operator is placed on the floor close to thebrooder-heater. If the floor .is springyythe flame, itself, will change as soon as the weight of the operator is removed. My improved compensating valve entirely overcomes "this trouble and'with its use,'there is no appreciable change in the flame due to these conditions. Fires have occurred where operators have stated under oath, that just a short time before the brooder had been examined, the tank refilled with oil, and the flame adjusted, and that it was burning a perfect and proper size flame. These fires have always occurred in buildings with wooden floors, principally in the cheaply constructed wooden floor brooder-houses. It is conditions like these, that my invention contemplates and it effectively overcomes these dangers and difiiculties.
