Application filed May 13, 1913.

To aZZ whom it may concern:

Be it known that I, FRANK C. Bonn, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Steam-Pressure Regulator Valves, of which the following is a specification.

My invention relates to improvements in steam pressure regulator valves in which the supply of fuel is regulated by the pressure of steam; and the objects of my improvement are, first, to provide a *alve by means of which the supply of fuel is regulated by the pressure of steam, and second, to provide adjustments by which the supply of fuel may be regulated with different pressures of steam, and third, to provide means for automatically controlling the supply of fuel to the steam producing burner. These objects, together with other objects readily apparent to those skilled in the art, I attain by the construction illustrated in the accompanying drawings, although my invention may be embodied in a variety ofother me chanical forms, the construction illustrated being chosen by way of example.

In the accompanying drawing l igure 1 is a side elevation of the regulator and valv Fig. 2 is a longitudinal section. Fig. 3 is a detached view of the fuel or gas regulating needle and its adjustable head. t is a view showing a portion of the valve illustrating the steam and spring controlled chambers together with the flexible disk or (llilpl'lltlglll dividing sheet chamber. Fig. 5 is a transverse section on line 55, Fig. 2.

Similar numerals of reference indicate corresponding parts in all the figures of the drawing.

In the accompanying drawing, 1 represents the steam chamber casing and 2 the spring chamber casing, which casings are connected together by means of a coupler or union 3, which coupler or union is of the ordinary construction. To the steam Cl121l11- ber casing 1 is attached the steam pipe 4, which steam pipe is connected to the radiator or other steam heating device in which steam is generated by a suitable burner connected to the body 5, which body is provided with a gas outlet aperture 6 or what might be more specifically termed the gas tip of the burner. The body 5 is provided with the valve casing Specification of Letters Patent.

' T, in which is located the valve 8, which valve is operated by the valve handle 9.

To the valve casing 7 is attached a fuel or supply pipe by means of the ordinary screw threads 10, said supply pipe being connected to any source of supply such as street pipes properly connected to a gasometer or other source of supply, reference being had to the kind of gas employed.

lVithin the steam chamber is located the screw threaded bar 11, which screw threaded bar is held in fixed adjustment by means of a screw threaded aperture formed in the end 12 of the steam casing l. in the spring controlled chamber 2 is located the spring 13, which spring is located around that portion of the needle bar 14-, which is extended into the spring chamber. Between the chambers formed by the casings 1 and 2 is located the flexible diaphragm 15, which flexible diaphragm is held in position by means of the flange 16 and the end of the spring chamber casing 17 as best illustrated in Fig. 4c. The screw threaded bar 11 is for the purpose of limiting the moveu'ient of the diaphragm caused by the action of the spring 1.3 and for the purpose of adjusting this movement of the diaphragm the screw threaded bar 11 is adjusted to or from said diaphragm 15.

The operation of the regulator is substantially as follows: When the steam pressure becomes below the pressure desired. thereby reducing the degree of heat. wanted, the spring 13 will move the needle bar Lt toward the diaphragm 15, thereby moving the needle point 18, away from the tip or aperture 6 and admitting a greater supply of gas to the burner and increasing the amount of steam and heat, which increased pressure when greater than desired will move the diaphragm 15 and the needle bar l t in the opposite direction and reduces the supply of gas to the burner, the said movement of the needle bar also contacts the spring 13. It will be noted that the supply of gas should not be entirely out off by the steam pressure, but when it is desired to cut off the supply of gas to the burner the valve 8 is closed by means of the handle 9.

It is well understood that in heating systems, the degree of heat desired varies from time to time, owing to different degrees of temperature and during excessive cold weather more heat is required than is necessary during periods of moderate temperature. In order to provide for the proper regulation of the heat with reference to weather conditions the adjustable sleeve 19 is provided, which sleeve is located upon the needle bar 14, and is provided with the flange 20, which flange forms an abutment for one end of the spring 13, the opposite end of said spring abutting against the inner end of the valve casing T.

It will be understood that by adjusting the sleeve 19 in opposite directions, the tension of the spring will be increased or decreased, reference being had to the adjustment of the sleeve 19, by which adjustment greater or less steam force is required so that the degree of heat may be automatically regulated to produce the desired amount of heat, reference being had to weather conditions as to heat and cold.

For the purpose of providing means for properly inclosing the extended end of the screw threaded bar 11, the steam chamber casing 1 is provided with the screw threaded extension 21 upon which is located the cap or cover 22, said cap or cover being for the purpose of giving the va ve proper, and neat appearance, and protecting the bar 11.

V For the purpose of providing for the escape of steam from the steam chamber the screw threaded extension 21 is provided with internal screw threads which are for the purpose of receiving the screw threads formed upon the packing holding sleeve 23, which sleeve is for the purpose of holding the packing 2%. In order that there may be no stopping of the flow of gas or possible clog ging during the time the valve 8 is open or partially opened, the needle bar 14: is provided with the angular portion or part 24, the apexes of said angular portion or part 24: being so arranged that they will come in contact or nearly in contact with the wall of the outlet gas passage 25 located through the burner body 5, thereby producing the gas passage 26.

Having fully described my invention what I claim as new and desire to secure by Letters Patent, is

1. In a device of the character described, the combination of steam and spring chamber casings, means for connecting said chambers together, said steam chamber provided with a screw threaded extension, the

spring chamber casin provided with a burner tipped body, a gas passage located through said body, a valve adapted to regulate the fuel supply to the burner tip, a needle bar partially located within the spring chamber casing and extended into the burner body, an adjustable sleeve located upon the end of the needle bar located in the spring chamber, said sleeve provided with an outward extended flange, a spring located around the needle bar and adapted to bear against the adjustable sleeve, a screw threaded bar partially located within the steam chamber and in the screw threaded extension, a diaphragm adapted to be clamped between the spring and steam chamber casings, a packing adapted to press against one side of the diaphragm, and a packing holding sleeve adjustably connected to the screw threaded bar, substantially as and for the purpose specified.

2. In a device of the character described, the combination of steam and spring chamber casings, means for connecting said chambers together, said steam chamber provided with a screw threaded extension, the spring chamber casing provided with a burner tipped body, a gas passage located through said body, a valve adapted to regulate the fuel supply to the burner tip, a needle bar provided with an angular portion and partially located within the spring chamber casing and extended into the burner body, an adjustable sleeve located in the spring chamber, said sleeve provided with an outward extended flange, a spring located around the needle bar and adapted to bear against the adjustable sleeve, a screw threaded bar partially located within the steam chamber and in the screw threaded extension, a diaphragm adapted to be clamped between the spring and steam chamber casings, a packing adapted to press against one side of the diaphragm, and a packing holding sleeve adjustably connected to the screw threaded bar, substantially as and for the purpose specified.

In testimony that I claim the above, I have hereunto subscribed my name in the presence of two witnesses.
