Specification of Letters Patent.

Patented May 11, 19515.

Application led November 15, 1911. Serial No. 660,325.

My invention relates to devices for regl/1% lating the supply of gas te the burners off water heaters which are actuated by the pressure and temperature 'of the water admitted therein, and the objects are, rst, to provide a doubly actuated gas valve that is simple, durable and safe, second, to provide such a valve that is positive in its action, third to provide such a valve that will not be azected by the overstroke of the thermostat or an over pressure of gas, fourth, to provide a novel means of thermostat and water valve connection to said gas valve, and fifth, to provide a substantial means for rigidly connecting said thermostat, gas and water valves in relation to each other.

With these and other objects in view as will appear, my invention consists of certain novel features of construction, combination and arrangement of parts, as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawings, and to the characters of reference thereon, which form a part of this specification, in which The figure is a sectional view of my valve" shownin operative connection with a water actuated valve and a thermostat, these latter parts being shown in elevation.

Similar characters of reference refer to similar parts throughout the several views.

The casing 1, valve 2, valve 3, spring 4, spring 5, valve stem 6, valve stem 7, stuing box 8, sg box 9, thermostat 10, support 11, and water valve 12 constitute the principal parts of my Water heater regulator.

The casing 1 contains two compartments 1a and 1b which are connected by a passage 1.

In the upper end of the casing in the compartment 1a is screwed a plug 1d and in the upper end of the casing into compart- 1 ment 1b is screwed plug 1. These plugs are adapted to facilitate the placing of the several parts in said compartments.

Tn the lower surface of compartment 1 is a valve seat 1f, and in the lower surface of compartment lb is a valve seat 1g, and adapt ed to fit the valve seat lt is a packing 2a which is supported by a flange on the valve 2. Fitting the valve seat'lg 1s a packing 3 which is supported by a flange on the valve 3. These valves are provided with guides 2b and 3b adapted to facilitate their engagement with said valve seats.

Connecting with valve 2 is a valve stem `6, which extends out Jthrough the plug 1d and is provided centrally and around said valve stem with a stuiing box 8. Connecting with the valve 3 is a similar valve stem 7 which extends in the opposite direction to valve stem 6, and is provided with a similar stuiing box 9. Connecting with the valve 2 is a compression spring 1, which is adapted to close and to keep the valve closed under certain conditions.

Tn connection with valve 3 is a compression spring 5 adapted to close and to keep the valve 3 closed under certain conditions.

ln line with valve stem 7 and adapted to engage with the end thereof is a water pressure actuated valve stem 12a, so that when the water pressure in valve 12 causes valve stem 12a to be pressed outward, it thrusts the valve stem 7 into said valve casing, thereby opening the valve 3 by compressing the spring 5, thus allowing the gas to iiow through these compartments in accordance with the flow or amount of water pressure through valve 12.

. Connecting with valve stem 6 is a lever 6'cx which is pivotally mounted upon a support 11 at the point 11, and mounted on lever 6a is a rod 6b which connects with a lever 10a, which is pivotally mounted on support 1l at the point 11b, and connecting with lever l0a is a thermostat adjusting bolt 10b, which is attached to the extended end of the thermostat 10. This thermostat 10 is a single piece of pipe provided with a plug 10c in its end and having an inlet l0d and an outlet 10e. This thermostat is rigidly attached to the support 11, at one end, and is supported by a guide 11C in which the thermostat is adapted to contract and eirpand. The thermostat support 11 is shaped as shown inthe figure, and is provided with extended lugs 11d and 11", and is provided on one side with a bracket'lug llf, which is adapted for attaching it to a water heater. This support l1 rigidly connects these valves and the thermostat together, thus providing a positive action.

The operation of the thermostat valve 2 is as follows The heated water enteringthe thermostat through the opening 10I will heat the thermostat, causing it to-elongate, which `in turn will relieve the leverl l0, which will relieve the lever 6, thus allowlng the valve stem 6 to be pressed into the' casingby means of the compression sprlng 4, which closes the valve 2. If however, the temperature of the water in the thermostat is not too high, the contraction of the lthermostat will compress the spring 4, thus opening the valve 2..

It will be readily seen that with this construction, there is provided a good and stubstantial water heater regulator; that lthe support connecting the several parts together, provides a means of holding the dlfferent parts, rigidly, in their relative positions; that the double actuated valves provide a positive means of regulating the supply of fuel to a water heater; that the single pipe thermostat construction, in connection with the valves, provides avery simple operative means.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. A water heater regulator comprising, a gas valve casing divided into two separate compartments and provided with an inlet and an outlet, a passage way connecting said compartments, a water pressure actuated gas valve, spring seated`on the pressure side in v one of said compartments, a water pressure actuated valve for opening said gas valve and permitting the How of gas from one compartment 1nto the other, a thermostat actuated valve normally seated by a compression spring on the pressure side in the other compartment of sald casing and adapted to control the flow of gas to a burner, a

',erated valve, and said support.

2. A water heater regulator comprising a supporting and connecting frame, provide with aI lug near itsmiddle, adapted to be rigidly attached to aiwater heater, a thermostat consisting of an elongated hollow casing, through which the heated water 'from the heaterl Hows',- rigidiy secured to said frame at one 'of its endsnear the -end of said frame, a guide rigidly secured to said supporting frame near the middle in which the other end of said thermostat is shiftably mounted, a doubly actuated fuel supply valve rigidly secured to said support'- ing and connecting frame, operative connections mounted o'n said frame between said supply valve and said thermostat whereby the movement oi said thermostat is enlarged to one of the actuating portions of 'said sup ly valve, and a watel` pressure actuated valve for actuating the ot er portion of said gas valve rigidly secured to said supporting frame, whereby 'said thermostat, fuel supply valve, operative connections and water pressure actuated valve are rigidly secured and connected together. y

In testimony whereof, I have hereunto subscribed my naine in the presence of two subscribing witnesses;
