UNITED STATES PATENT OFFICE.
WILLIAM J. QUINN, OF BALTIMORE, MARYLAND, ASSIGNOR TO THE HENRY MCSHANE MANUFACTURING COMPANY, OF SAME PLACE.
LoBE-VALVE.
SPECIFICATION forming part of Letters Patent No. 485,055, dated October 25, 1892.
Application led June 2, 1892. Serial No. 435,286. (No model) I To all whom it may concern:
Be it known that I, WILLIAM J. QUINN, a
` citizen of the United States, residing at Baltimore, in the State of Maryland,`have invented certain new and useful Improvements in Globe-Valves, and I do hereby 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.
This invention has relation to globe-valves such as are especially designed and adapted for use on steam pipes and fittings, and has for its object the provision of novel means for rendering the valve perfectly steam -tight when turned down upon its closing-seat and for preventing leakage when the valve is raised and caused to seat against the under side of the box, as may be sometime required when it is necessary to renew the packing in the upper part of the box.
This invention has for its further objct the provision of a novel construction and arrangement of the valve proper and of the collar and nut by which it is secured upon the spindle, whereby the valve is rendered reversible, the packing-disk made interchangeable and reversible, and the valve prevented from turning and grinding or wearing after being seated.
My invention consists in the novel construe tion, combination, and arrangement of parts as hereinafter described and specifically claimed.
In the accompanying drawings, Figure l is a vertical central sectional view of a globevalve embodying my invention. Fig. 2 is a horizontal sectional view of the same on the line X X of Fig. l.
The valve-casing A is of the usual construction, and is provided vwith th'e box B, through which passes the spindle D, carrying on its lower end the valve E. Above the internallyscrew-threaded part of the box B the ordinary cavity h is formed for the reception of packing material. A screw-threaded cap c surmounts the box B and is formed with a central opening for the passage of the smooth cylindrical portion of the valvestem. On the under side of the box B is formed an annular valve-seat F, against which the upper side of the valve is pressed and the valve seated when the latter is raised to its highest point of adjustment.
The valve E for the purposes of my invention consists of a cylindrical block or head, having a central opening for the passage of the spindle D, and having in its upper and lower faces cylindrical cavities or recesses for the reception of the vulcanized packing-disks 6o G G', which fit snugly in place and have central openings corresponding to the central openings in the web ofthe valve-head. When the valve-head is in place upon the spindle, the upper surface of the disk G rests against a collar h, formed upon the spindle D, and the Valve is held in position by means of a flanged capnut I, which screws upon a threaded tenon on the lower end of the valvespindle, a shoulder 7i; being left on the spindle 7o to prevent the nut from being screwed up tightly enough to bind the valve-head or prevent' easy rotation. It is important and very desirable that the valve-head should have a certain amount of play upon the spindle and that it should be able to freely rotate upon the same, so that when the valve is seated upon its annular seat C the valve-stem may be turned independently of the head and the valve tightly compressed against its seat with- 8o out turning or grinding upon the same. Then the valve is raised as high as possible,its upper surface seats against the annular liange F and produces a perfectly-steam-tight joint, which permits of the cap e being removed and the spindle-box packed without danger of leakage.
It will be seen that the packing-disks G G and the recesses in the valve in which said packing-disks t are exactly alike in shape 9o and dimensions, and that under these conditions the valve-head may be reversed on the spindle, either disk inverted, or the disks interchanged, so that the wear upon the disks may be readily compensated for and their serviceableness greatly prolonged.
The valve E, as already indicated, is loose upon the stem D. Hence when the valve is lowered upon its seat C the upper disk G is compressed tightly against the collar h, thus 10o producing a tight joint around the collar and preventing leakage at that point, and when block or head having like recesses in its upper and lower faces containing reversible and interchangeable packing-disks, substantially as described.
In testimony whereof I affix my signature in presence of two witnesses.
WILLIAM J. QUINN.
