GEO. II. KITCHEN,
OF NEW YORK, N. Y.
CONSTRUCTION OF GAS-REGULATORS.
Specification of Letters Patent No. 25,834, dated October 18, 1859.
have invented a new and useful Improvement 1n the Construction of Gas-Regula- 1 tors; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, forming part of this specification, in which Figure 1, is a central vertical section of the gas regulator. Fig. 2, is a horizontal section of the same in the plane indicated by the line w, w, of Fig. 1.
Similar letters of reference indicate corresponding parts in both figures.
My invention consists in a certain novel system and arrangement of passages surrounding a chamber in which works a cup shaped or diskiform valve that is operated upon directly by the pressure of the gas, whereby the said valve is caused, by the action of the gas upon it, to regulate the flow of gas to the burners under all conditions by giving an enlarged opening to the passages as the valve is raised and a diminished opening as the valve is depressed.
To enable those skilled in the art to make and use my invention I will proceed to describe its construction and operation.
A, is the chamber or external portion of the regulator whose general form is that of an upright cylinder having an internal screw a, at the bottom to enable it to be screwed onto the outlet nozzle B, of a gasmeter or on to the end of a service pipe and having an external screw 6, at the top to connect the pipe 0, which supplies the burners it is intended to regulate. This chamber which may be made of brass or other metal is bored out cylindrically and smoothly from the top nearly to the bottom, where there is provided a valve seat 0, which has a slight downward bevel toward the center to prevent the collection thereon of any of the impurities of the gas and to allow them to run back into the meter or service pipe. In the sides of this, chamber, at equal distances apart above the valve seat 0, there are a number of recesses d, d, which terminate in points close to the valve seat and have a gradually increased width to the top of the chamber as shown in Fig. 1. Between these recesses, are left the projections e, 6, whose faces are portions of the face of the cylindrical bore of the chamber.
D, is the regulating valve which I prefer to make of the form of an inverted cylindrical cup, as represented in the drawing, but which might consist of a disk. This valve may be made of brass or other metal and has a sharp edge at its bottom to prevent it sticking on the seat (I. It is fitted closely, but so as to slide freely up and down, within the cylindrical bore of the chamber, so as to leave no passage for the gas between it and the chamber except the recesses d, d. The area of the passages formed by the recesses outside of the valve it is obvious will be greater or less as the valve is higher or lower in the chamber, and when the valve is on its seat the gas is completely shut off.
The operation of the regulator is as follows: When the gas is entirely shut off,
either at the burners or at the meter the valve rests upon the seat 0. When the cock at the meter or in the service pipe is opened and the gas is turned onto one or more burners by their respective cocks, the valve which is made of suitable weight is raised by the pressure of the gas against the underside of its head to such a position as to give the required aggregate area of passage to supply the requisite amount of gas and so remains as it were floating steadily on the gas till more burners are opened or some are shut off, or until some variation of the pressure in the main pipe occurs. In case of more of the burners being opened a reduc tion of the pressure above the valve takes place by reason of the more free escape that is provided, and the valve is consequently raised by the pressure of the gas below and thus brought opposite to wider portions of the recesses d, d, and a sufliciently greater area of passage for the gas is obtained to compensate for the increase of the number of burners in operation and the valve then becomes stationary again, but in case of some of the burners being closed the opposite effect is produced on the valve by the increase of pressure that takes place on its upper side; and in either case if the recesses (Z, d,
reduction of the pressure in the main taking place the opposite efi'ect is produced. Thus a perfect regulation of the light from each burner has been found in practice to be obtained under all conditions.
I am aware that there are gas regulators in use consisting of inverted cup and diskiform valves acted upon directly by the pressure of the gas to regulate the area of certain passages and therefore I do not claim broadly the invention of such a regulator; but such regulators have generally been applied, separately, to each burner, and have only been required to provide against the effects of variable pressure below the valves, and the passages have been contracted by the upward movement of the valve and enlarged by its downward movement, which GEO.
