JACOB PODOLSKY, OF BOSTON, MASSACHUSETTS ANTISIPHON DEVICE FOR KITCHEN-RANGE BOILERS.
Application filed June 25, 1913.
T0 (1N tllhO'lIl it may, concern Be it known that I, JACOB PoDoLsnY, a citizen of the United States, residing at Bos ton, county of Suffolk, State of Massachusetts, have invented an Improvement in Antisiphon Devices for Kitchen-Range Boilers. of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.
This invention has for its object to provide a novel device to be used in connection with kitchen range boilers to prevent their collapsing in case the water siphons out of them. The device comprises an air inlet port with means for normally holding said port closed so long as the boiler is full, which means operates to open the air inlet port to admit the water into the boiler when ever the water left in the boiler falls below a predetermined amount, the air which is thus admitted operating to break the siphon and prevent the boiler from being emptied or collapsing.
In order to give an understanding of the invention, I have illustrated in the drawings a selected embodiment thereof it being understood that the constructional features shown may be varied in many ways without departing from the invention.
Figure 1 is a side view of a kitchen range boiler, having my means applied thereto. Fig. 2 is an enlarged sectional view through the anti-siphon device.
I have shown at 1 an ordinary kitchen range boiler having the water inlet pipe 2 through which water is delivered to the boiler and the eduction pipe 3 from which the water is withdrawn from the boiler.
It sometimes happens that owing to certain manipulations of the valves or faucets connected with the water supply system, the water will start to siphon out of the boiler through the supply pipe 2 and when this occurs the boiler is very apt to collapse. The device I have herein illustrated is for the purpose of preventing this from happening. It comprises a casing or chamber at which has communication with the interior of the boiler and which may be directly connected to the boiler or may be in the supply pipe 2 so that the water entering the boiler will pass through the casing 41-, this latter being the construction herein illustrated. Situated within the casing 4: is a hollow Specification of Letters Patent.
Patented Nov. 17, 1914.
Serial No. 775,681.
member shown as having a nipple 6 at its lower end which terminates in a valve seat 7. The member 5 is also provided with a laterally extending nipple 8 which extends through one side of the casing a and which has secured thereto an extension 9 provided with an air inlet port 10. The port 11 through the nipple 6 is normally closed by a valve 12 which seats against the valve seat 7. This valve has a stem 13 connected thereto which stem is operatively connected to the valve stem 14: of an air valve 15 that normally closes the air inlet port 10. The connections between the valve stems 13 and 14 may be of any suitable construction. I have herein shown for that purpose a bell crank lever 16 which is pivoted at 17 within the member 5 and the arms of which are pivotally connected to the valve stems 13 and 14.. The valve 12 has connected thereto a float 18 which constitutes the means for normally keeping the valves 12 and 15 closed. This float and the valve 12 are located within a housing 19 which is secured to the nipple 6, but is open at the bottom.
The operation of the device will be understood. So long as the boiler 1 and the casing l is filled with water the buoyancy of the float 18 will keep the valve 12 closed against the seat 7 and will also keep the air valve 15 closed. when these two valves are closed no water can leak out through the ports 11 and 10. If, however, the water in the boiler 1 begins to siphon out therefrom so that the water level drops below the float 18 then the weight of the fioat operates to open the valves 12 and 15 to allow the entrance of air into the casing at. This breaks the siphon and vents the boiler so as to prevent it from collapsing.
\Vhile I have illustrated one embodiment of my invention, I do not wish to be limited to the constructional features shown.
Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:
1. In an anti-siphon device for range boilers, the combination with a supply pipe leading into the boiler, of a casing communicating with said pipe and through which the water passes in its course to the boiler, a hollow member within said casing and having communication therewith, an air inlet port leading to said member, a valve for closing said port, and a float within the easing and connected to the valve for maintaining the valve closed so long as the boiler is filled.
2. In a device of the class described, the combination with a supply pipe for supplying water to a boiler, of a casing communicating with said pipe and through which the water passes in its course to the boiler, a hollow member within the casing and provided with a port leading thereto and also with an air port, a valve for each port, and a float situated within the casing and connected to said valves.
3. In a device of the class described, the combination with a supply pipe leading to a boiler, of a casing communicating with said pipe, a hollow member within the casing and provided with a port leading thereto and also with an air inlet port, a valve for each port and a float situated within the casing connected to said valves and an open bottom housing connected to the hollow member for inclosing and protecting the float.
4. In an anti-siphon device for range boilers, the combination with a casing adapted to communicate with a range boiler, of a hollow member within said casing and pro vided with a port leading thereto and also with an air port, a valve for each port, and a float situated within the casing and connected to said valves.
5. In an anti-siphon device for range boilers, the combination with a supplypipe leading into the boiler, of a casing communicating with sad pipe and through which the water passes in its course to the boiler, a hollow member within said casing communicating therewith, an air inlet port leading to said hollow member, a valve for closing said port, a float within the casing secured to the valve, and means within the casing partially inclosing the float and protecting the latter.
In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
