Description

June 11, 1935. R. E. WARREN 2 FLOW CONTROLLING MECHANISM Filed Feb. 1, 1952 trolling the inflow of water,
Patented June 11, 1935 I l 5* UNITED STATES PATE NTOFFICE v This invention relates to a flow controlling mechanism.
An object of the invention is to provide a mechanism of the character described for'conparticularly into a boiler. a
Another object of the invention is to provide in a mechanism of the character described a novel type of valve employed.
Another object of the invention isvto provide novel means for actuating the valve. r r With the above and other objects inview, the invention has particular relation to certain novel features of construction, operation and arrangement of parts an example of which is given in this specification and illustrated in the accompanying drawing, wherein:-
Figure 1 shows a side view of the mechanism as mounted on a boiler and,
Figure 2 shows a sectional view of the valve.
In the drawing the numeral I designates a boiler or other container leading into the top of which there is a supply pipe 2 incorporated into which is the valve casing 3. The supply pipe 2 leads into one side of the valve casing and is connected to the top thereof by means of a suitable coupling 3". Threaded into the inner end of this coupling there is an outwardly tapering valve seat 4 and in the casing there is a valve 5 having ment and stufling box and normally tends to open the valve. There is a lever l0 pivotally mounted on the boiler and whose outer end has a pivotally sliding connection withthe outer end of the stem 6, and whose other end is extended beyond the pivotal support of said lever. There is a float H adapted to ride on the water in the boiler I and which is attached to the free end of the arm 1 Claim. (01. 251-434 I l2. The otherend of this arm is fixed on a shaft i3 which rotates in a bearing l4 in the side, of. the boiler and fixed to the outer end of said shaft l3 there is an arm [5 whose free end is connected to the extended end of the lever ID by means of the link i6. 7 i
As the level of the water in the boiler rises the float II will rise with it, operating through the mechanism described to lift the valve 5 and to close the seat 4 to shut off the inflow of water, meanwhile placing the spring 9 under compression. Pressure in the casing 3 will tend to hold said valve closed. 7 v t Asthe Wat-er level is lowered in the boiler the float I I will descend 7 operating through the mechanism described assisted by the spring 9 to open the valve 5, and to again admit water to the boiler.
The inner end of the valve 5 is tapered as in I! so as to offer a minimum resistance to the water in the casing 3 as the valve is moved to open povention by way of illustration only, 'While the tion with said stop, a flow line entering the side of the chamberan-d leading outwardly therefrom through said seat, a valve in said chamber opposing endof these'at when the valve is closed,
a valve stem attached to the other end of the valve, astuifing box carried by the casing through which said stem works and yieldable means normally tendingto hold the valve open.
