GOMB INATTON GAS AND WATER VALVE.

Specification of Letters Patent.

Patented June 9, 1903.

Application filed. July 10, 1906. Serial No. 325,524.

To all whom it may concern:

.Be it known that I, HERBERT S. HUM- PIIREY, a citizen of the United States, residing at Kalamazoo, county of Kalamazoo, State of Michigan, have invented certain new and useful Improvements in Combination Gas and Water Valves, of which the following is a specification.

This invention relates to improvements in valves.

It relates particularly to improvements in automatic water and gas valves for water heaters, although it is adapted for use in other relations.

. tak n on a The objects of this invention are: First, to provide an improved valve for water heaters, which compels the incoming or supply water to pass through the heater, and also permits the water in the system to circulate or ass'through the heater when the supply Va ve is closed. Second, to provide an improved automatic water and gas valve in which the quantity of gas delivered is con- 7 trolled by the quantity of the water delivered,

which may be readily adjusted. Third, to provide in a valvean improved means for adjusting the delivery port of the valve. Fourth, to provide an improved combination automatic water and gas valve for Water heaters, which is simple and econom ical in structure'and convenient in use, and

one which is not likely to get out of repair in use.

Further objects, and objects relating to Figure. 1 is a detall elevation of a structure embod ng the features of my invention, portions the water heater casmg being broken away show the relation of the parts, and (.letailsonly of the circulating system being shbwn. Fig. 2 is a detail vertical section,

line corresponding to line 2 Z of /l i g. 1, showing the structural details of the valves. Fig. 3 is a detail transverse section,

taken on. a line corresponding to the broken line 33 of Fig.2. Fig. 4 is an enlai ed perspective of the adjustable member or controlling the port or passage of the inlet valve.

In the drawing, the sectional views are taken looking in the direction of the little arrows at the ends of the section lines, and similar numerals of reference refer to similar parts throughout the several views.

Referring to the drawin ,the casing 1 of the water heater may be 0 any desired construction, the structure illustrated being a double wall. Within this casing is the Water heating coil 2, below which the burners, as 3, are arranged. The water heater is provided with a suitable flue, as 4, for the discharge of the gases of combustion. 5 of the water heater leads to the circulation The discharge pipe 1 system, which is here illustrated in conventional form only. The water supply pipe 6 v is connected to the inlet pipe 7 of the heating coils. The gas sup ily pipe 8 is connected by the pipe 9 to the urner. ,The circulation tank 10 is connected by the return pipe 11 to the inlet pipe 7 of the heating coils. The water inlet pipe, the circulation pipe, and the gas supply pipe are controlled by an automatic water and gas valve, the details of which are illustrated in Figs. 2 to 4, inclusive. This valve comprises a casing 12, provided with an inlet passage 13, a circulation passage 14, and an outlet or discharge passage- 15. The inlet passage 13 is connected to the water supply pipe 6, and the circulation passage 14 is connected to the return pipe 11 of the circulation system, while the discharge passage 15 is connected to the inlet pipe 7 of the heater.

For convenience in referring to the parts, 1 herein designate the passage 1.4 as the circulation passage, and the valve 17, which controls this passage, the circulation. valve. The valve casing 12 is provided with a chamber for the main or inlet valve 16, intowhich the inlet passage 13 opens; and also with a chamber into which the circulation passage 14 opens for the circulation valve 17. The inlet valve 16 is a piston valve,- and preferably carries the circulation valve 17, which is preferably formed integral therewith, as is illustrated in the accompanying drawing.

The valve 17 in the structure illustrated is cylindrical in form, with notch-like ports in its lower end, which parts are open when the ,inlet valve is in its upper or closed position, and closed when the inlet valve is.o ened; so that, when the inlet valve is cosed, a circulation of water through .the heater and the circulation system is permitted. The discharge port for the in- -et* valve is formed in one side of the main valve chamber, and is preferably provided so that the delivery of water is increased as the valve is opened. This I preferably accomplish by tapping a hole or chamber 18 into the valve casing, so that one side of the same opens into the inlet valve chamber. In this chamber 18, I arrange the block 19 which is supported. adjustably therein by means of the stem 20, which is threaded into the block. The block '19 is tapered'or inclined on its inner face, as at 21, so that, as the valve 16 curves downwardly, the area of the ort is increased. The block 19 is preferab y cylindrical in general form, and is prevented from turnin by the pin 22, which projects into the hofia 23in the block. The

stem 20 is provided with a suitable packing,

consisting preferably of the ring 24, which is arranged against the collar 25 of the stem. A block-like gland 26 is threaded into the casing. Between the ring 24. and the gland 26 is a packing 27. These parts are all ar- 1 ranged III the 'ihig 28, thIGSM ed into the casing, which is arge enough to ermit the insertion and removal of the ock 19 therethrough.

The valves 16 and 17 are so arran ed that the valve 17 is always closed when t e valve 16 is opened, so that, when the valve 16 is opened, the water is compelled to ass to the heater, instead of circulating, bac through the circulation system. The valve is designed to be automatically operated by the water pressure, so that, when the water is 40 turned on or the pressure in the system falls below that in the sup ly,as is occasioned by the drawing off 0 water from the systemthe valve 16 is automatically opened; and, when the ressu're is equalized,as by the closing of a aucet,the valve 16 is again closed. A spring 29 is provided for this purpose. This spring is preferably arranged un der the piston valve 16, within the circulation valve, 17 and the chamber, as illustrated. When the inlet valve is closed, the circulation valve is opened, so that the water in the system is free to circulate through the heater.

The valve 16 is provided with a stop 30, which is held normally against the top of the valve casing by the spring. The gas valve casing 31 is connected to the casing 12 by a suitable yoke, as 32. The gas valve casing is provided with an inlet passage 33, to which the supply pipe 8 is connected, and with a discharge passage 34, to which the burner pipe 9 is connected.

The delivery of the gas is controlled by the valve 35. The structure and arrangement of the gas valve is preferably that illustrated and described in my Letters Patent dated portion to the amount of Water passing through the main Water valve, as is pointed out in my atent above referred to. The valves in t e accom anying drawing are shown in their close positions. The arran ement of the pilot light valve is also reFerably that illustrated in my patent reerredto, the pilot burner 39 being connected by the pipe 40 to the valve casing.

By arranging the parts as I have illustrated and described, the assage of the water is effectively controlled the valve being automatic in its operation in controlling both the delivery of the water and the gas, and permitting the circulation of the water in the system through the heater when the inlet valve is closed, and compelling the circulation of the fresh or incpming water to the heater when the inlet valve is opened. The structure" is compact and simple, and not likely to get out of repair.
