UNITED STATES PATENT OFFICE.
WILLIAM C. MILLER, OF LINCOLN, NEBRASKA, ASSIGNOR OF ONE-HALF TO SYDNEY CIWHEELER, OF WYMORE, NEBRASKA.
PRESSURE-REDUCING VALVE.
SPECIFIGATION forming part of Letters Patent No. 643,519, dated February 13, 1900-. Application filed September 6,18991 Serial No. 729,599. (No model.)
To all whom it may concern:
Be it known that I, WILLIAM G. MILLER, a
citizen of the United States, residing at Lincoln, in the county-0f Lancaster and State of Nebraska, have invented certain new and useful Improvements in Pressure-Reducing Valves; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to improvements in.
pressure-reducing Valves, and more particularly to that class employing a corrugated expansion-diaphragm and the objects are to improve the construction and prevent the rupture of the diaphragm in the event of an excess of pressure.
To this end the invention consists in the construction, combination, and arrangement of the several elements of the device, as will be hereinafter more fully described, and particularly pointed out in the claim.
In the accompanying drawings the same reference characters indicate the same parts of the invention.
Figure 1 is a perspective view of my improved pressure-reducing valve. Fig. 2 is a vertical transverse section of the same. Fig. 3 is a horizontal section showing a top plan View of the sectional segmental diaphragm open, and Fig. 4 is a similar view showing the same closed.
1 denotes the valve-casing, and 2 the removable cap or cover, which is provided with a tubular extension 3, having a removable screw-cap 4. The valve-casing terminates in a sleeve 5, which is internally threaded to receive the adjusting-plug 6 and externally threaded to receive the cap 7, which protects the plug.
8 denotes the pressure-spring, the lower end of which rests upon the adjusting-plug 6, and its upper end is encompassed by a socket 9, terminating in a stud-post 10, upon which the corrugated diaphragm 11 rests, the outer peripheral edge of which is clamped inthe usual manner between the casing 1 and the cap 2. The stud-post 10 is formed with a circumferential groove 12 to receive the inner edges of the sectors 13 13, which form a sectiona-l diaphragm, the onteredges of which rest upon the rabbeted shoulder 14, formed in the valve casing. This sectional diaphragm entirely encompasses the lower face of the corrugated diaphragm, so as to form a shield when excessive pressure is employed and prevent the rupture of the main diaphragm.
The extension 3 is provided with an outlet connection 15, and within the extension 3 is a sleeve 16, in which is mounted a movable post or stem 17, the lower end of which rests on the diaphragm l1, and its upper end rests against the face of a feed-Valve 18, which seats on the upper end of the sleeve 16-and is held in contact therewith by a superimposed spring 19, seated in the cap 4. It will be noted that the feed-valve stem 17 is longitudinally slotted, which allows convenient access to the valve and stem for cleaning.
20 denotes the inlet connection to the diaphragm-chamber 21, through which connection the air, gas, or liquid is conducted to the point of consumption. Lugs 29 29 extend down from the central portion of the cover2 to within ashort distance of the diaphragm 11, but do not quite contact with it normally, thereby preventing the closing of the diaphragm-chamber 21.
The operation of the device is as follows: The air, gas, or liquid being admitted to the casing through the inlet connection 20 passes under the valve 18, which is raised by the pressure-spring 8, down through the sleeve 16 into the diaphragm-chamber 21 and outlet connection 15 to the. point of consumption, the spring 8 being adjusted to the normal pressure required to hold the valve 18 open. If this normal pressure is increased, it overcomes the tension of the spring 8 through the medium of the diaphragm 11, which lowers the stem 17 and allows the valve 18 to seat and cut off the pressure, which, being removed from the diaphragm 11, allows the spring 8 to react, and thus raise the valve again.
It will of course be understood that various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.
Having thus fully described my invention, what I claim as new and useful, and desire to protect by Letters Patent of the United States, is
In a pressure-reducing valve, the combination of the va1ve-casin terminating in a sleeve 5 both externally and internally threaded at its lower end and exteriorly threaded at its upper end; the stud-post 10 formed with a circumferential groove; the socket 9 seated in said valve-casingg the pressure-springSlocated Within the socket 9 and sleeve 5; the corrugated diaphragm 11 and the sectional diaphragm formed of the sectors 13 13; the adjusting-plug 6; the protecting-cap 7; the tubular extension 3 provided with a removable screw-cap at; the outlet 15 leading from said extension 3; the sleeve 16 located Within said extension; and the movable post or stem 17 mounted within the sleeve 16 and having 20 In testimony whereof I have hereunto set 2 5 my hand in presence of two subscribing Witnesses.
