COMBINED GAS AND WATER COCK FOR WATER-HEATERS.
SPECIFICATION forming part of Letters Patent No. 690,413, dated January 7, 1 902. Application filed May 5, 1900. Serial No. 15,567. (No model.)
To aZZ whom it may concern.-
Be it known that I, WILLIAM B. FOLGER, a citizen of the United States of America, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in a Combined Gas and Water Cook for Water-Heaters, of which the following is a specification.
The object of my invention is a combined water-valve and gas-cockfor those heaters in which water is heated by ignited gas, formed in a single casting, by means of which the gas is turned on and kept so turned on by the flow of water through the water-valve, even though the pressure of the flow be low, is-
turned off effectually when the flow ceases, and in which the parts do not stick nor work hard after standing. This object is attained by the means described in the annexed specification and illustrated in the accompanying drawings, in which Figure l is a front elevation of a combined water-valve and gas-cock embodying my invention. Fig. 2 is a central vertical longitudinal sectional view of the same. Fig. 3 is a transverse sectional view of the same, taken upon line so so of Fig. 2 looking toward the left.
cation.
Referring to the parts, the cylindrical casing A of the water-valve aand the casing B of the gas-cock are formed in a single casting. CasingA has a lower externally-screw-threaded extension forming an inlet a to receive a water-supply pipe, and a lateral externallyscrew-threaded extension forming outlet at to receive the pipe leading into a water-heater. (Not shown.) The top of the casing is closed by a cap a Within the cylindrical bore of the casing is the piston-valve Ct, which hasa stem a extending up into cap a and a downwardly-extending stem 0?, upon the end of which is a nut a to hold thereon a loose cylindrical weight (0 Between piston CL- and weight a is a Washer a which has a downwardly-projecting annular flange a". When the water is turned on, it throws weight a? against washer a so that the outer beveled edge of the weight bearing against flange a spreads it outward and makes it fit snugly against the walls of the casing. Within casing A and journaled in its walls is a trans- Fig. 4 is a front elevation of a modifiverse shaft a upon which is secured a lever a whose end extends into a slot (L12 in stem 02*. Shaft a extends through the front of casing A and outside of the casing has a lever a secured to it. A by-pass on forms communication between the upper partof the casing and outlet 0, to allow any water which leaks past piston a into the upper part of the casing to pass out, so that it creates no back pressure when piston is raised.
Casing B of the gas-cock has a lateral internally screw threaded extension forming inlet b to receive a gas-supply pipe, and a rearwardly-extending externally-screw-threaded extension forming outlet 1) to receive the gaspipe leading into the jets in the heater. Casing B has a transverse bore, which is to receive a conical plug-valve b and from which extends a lateral passage b into the inlet b, a downward passage b into the outlet 1), and an upper narrow passage b into the secondaryplug-valve Z)", which regulates the lighter 12 which is kept burning constantly. Plugvalve b has an angular passage 17 to register in the open position with passages 19 and b and upon its front end is secured a lever b which is coupled to lever a by a link b When piston a is raised by the water, lever a is rotated to the right, communicating a similar movement through link 19 to lever b, which rotates plug-valve b so that passage 6 places. inlet 6 in communication without outlet 1) turning the gas on in the heater. The valve and cook are returned to their normal positions by a weight C, attached to the end of shaft (1 Secondary plug-valve b has secured upon its end a lever b, which is connected bya link 12 to lever b". When levers a and b are rotated toward the right, as above described, turning on the water and the gas within the heater, secondary plug-valve b is rotated so that channel Z7 in it puts passage 19 in direct communication with lighter b sending a greatly-increased flow of gas into it, so that its flame shoots out across the jets in the heater to ignite the gas issuing therefrom. When water-valve and gas-cock are shut off, the gas passes into the lighter from the inlet by means of contracted channels h and Z2 in the secondary plug, as shown in Fig. 2. To form a passage into the lighter while plug i) is turning, the latter has a semicircular groove b extending around it, as shown in In the modification shown in Fig. at in place of levers a and b shaft 0. and plug 5' have intermeshing cog-wheels (L and I)" attached to their ends, which are coupled by links a, and 19 to a slip-block d, which slides on a rod d, secured to the casting. Upon the rod is likewise a sliding weight D, which returns valve a to its normal position and closes the gas-cock when the flow of water is cut oif.
As seen in Fig. 2, the piston and the washer in their lowered position fit the water-cylinder loosely, so that there is little tendency in them to stick after standing. The jar of weight a when it is thrown upward against the under side of piston a, overcomes whatever of this tendency there may be in the parts. The pressure of the flow necessary to open and keep the water-valve open needs to be but little more than that ot the combined weights of the weights a and O, and when the flow ceases these weights bring the parts effectually to their normal position shown in Fig. 2. This combined with the simplicity of construction and the absence of packed joints overcomes any danger of leakage either from gas or water.
What I claim is 1. In a combined water-valve and gas-cock a Watersupply pipe, a casing interposed therein, a piston within the casing to be carried to and held in its open position by the flow of water in the pipe and having a downwardly-projecting stern, a weight mounted loosely upon the stem to be thrown upward against the valve by the pressure of the water when turned on, a gas-supply pipe, a casing interposed therein, a valve in the casing for regulating the flow of gas, and means for coupling the piston and the valve whereby the flow of water controls the flow of gas, substantially as shown and described.
2. In a combined water-valve and gas-cock a watersupply pipe, a casing interposed therein, a piston within the casing to be carried to and held in its open position by the fiow of water in the pipe and having a downwardly-projecting stem, a washer upon the stem below the piston, a cylindrical weight retained loosely on the stem to be thrown upward against the washer by the water when it is turned on, a shaft journaled in the casing, means for coupling the shaft and the piston whereby the piston rotates the shaft, a gas-supply pipe, a casing interposed therein, a rotatable plug-valve in the casing for opening and closing ofi the flow of gas through the pipe, and means for coupling the rotating 6o shaft and the plug-valve whereby the rotation of the shaft caused by the flowing of the water in its case is com municated to theplugvalve to turn on the gas, substantially as shown and described.
3. In awater-valve and a gas-cock the combination of a piston to be raised by inflowing water, a shaft to be rotated by the raising of the piston, a lever attached to the end of the shaft, a rotating plug-valve for opening and shutting off the How of gas through the cook,
a second lever attached to the plug-valve, means for coupling the lovers to communicate the motion from one to the other, a lighter, a channel for supplying it continuously with gas, a secondary plug-valve interposed in the channel having'an enlarged and a contracted opening therein through which the gas passes to the lighter, a lever secured to the secondary plug-valve, a link connecting it with said 89 second lever for rotating the secondary plug to put the lighter in direct communication with the enlarged channel therein, substan tially as shown and described.
