COMBINED STOP AND CHECK VALVE.
SPECIFICATION forming part. of Letters Patent No. 315,273, dated April 7, 1885.
Application niedmyiiss'i." (No modela To all whom it may concern:
Be it known that I, LEANDER G. GILBERT, of the city of Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Combined Stop and Check Valves, of which the following is a specification.
rlhis invention relates to that class of valves which are designed to be used either as a stopvalve or as a check-valve, and in which aball or spherical valve is employed.
The object of my invention is to provide a valve of this character which can be readily changed from a stop-valve to a check-valve, or vice versa, and in which a perfectly steam or water tight joint is obtained.
My invention consists to that end of the improvements which will be hereinafter fully set forth and pointed out in the claims.
In the accompanying drawings, Figure l represents a longitudinal section of my improvement, showing` the parts in position whereby the valve can be used as a stop-valve. Fig. 2 is a similar viewshowing the parts in position, so' that the valve can be used as a checkyalve. Fig. 3 is a side elevation of the valve and connecting parts removed from the valve-casing. Fig. Li is a horizontal section in line x x, Fig. 1. Fig. is a horizontal section in line y y, Fig. 2.
Like Vletters of reference refer to like parts in the several figures.
A represents the valve-casing provided with the usual inlet and outlet ports c a.
B is the valve, and b the valve-seat formed in the casing A. The valve B-is of spherical form, and is preferably made of metal.
C is an open cylindrical cage surrounding the valve B, and arranged vertically in the cylindrical enlargement A of the casing A. The cage C consists of an upper and a lower ring, c c', connected by vertical ribs c2, the lower ring, c,being provided with an inwardlyprojecting flange, which forms a seat for the valve when the cage is raised and retains the valve within the cage. The upper ring, c, is provided with an internal screw-thread,and is secured to a ring or cover, d.
D is a hollow stem secured to the ring d by suitable collars,d d2, and extending upwardly through a sleeve or cap, E, which closes the cylindrical enlargement A of the casing.` The n l E is closed at its top :by `a screw-nut, F,
which is provided with a suit-able packing, forming atight joint between the bore of the sleeve E and the stem D in the usualmanner. The stem D is provided above the collar d2 with an external screw-thread, g, and the sleeve E is provided with an internal screwthread, h, which receives the thread g of the stem D. The latter is providedat its upper end with a suitable hand-wheel, H.`
I is a rod extending through the hollow stem D and providedfat its lower end with a screwj thread, i, which works in an internal screwthread, j, formed in the stem D.
7c is a screw nut or cap secured to the top of the tubular stem D, and provided with a suitable packing, whereby a tight joint is formed between the tubular stem and the rod I. The latter projects through the screw-nut 7c, and is provided with a flattened head, i', to receive a wrench or other suitabledevice for turning it. Vhen the rod I is screwed down so that its lower end bears upon thezvalve B, the latter is clamped between the rod I and the flange c3 at the lower end of thecage, and the valve can be raised and lowered with the cage by turning the screw-stem D, and be opened and closed like an ordinary stop-valve.
When the valve is desired to be used as a checkwalve, the rod I is adjusted to clear the i Y valve, as shown in Fig. 2, when the valve is free to move vertically in the cage G and seat itself automatically. The cage C retains the ball in position above the valve-seat and prevents any lateral'movement or wedging ofthe valve in its seat. The valve Bean turn freely in the cage, and will constantly change its position in its seat by the pressure of the steam or water against the valve when open. By this means any unequal wear of the valve is prevented, and a perfectly-tight fit of the valve in its seat is assured at all times.
I claim as my invention- 1. The combination,with a valve-casing, of
a cage provided with a valve-support, ia lstem attached to said cage, a ball-valve ,arranged within the cage, and a locking-screw` whereby the valve can be` secured in the cage against IOO said valvesupport,thereby enabling the valve to berlifted from its seat with the cage when desired, substantially as set forth.
2. The combination, with a ball-valve and its casing, of a cage, C, provided with a valvesupport, and a tubular stem, D, attached to the cage, and a screw-rod, I, adapted to bear against the valve B,substantially as set forth.
3. The combination, with a ball-valve, B, and its casing, of a cage, C, provided with a valve-support, and inclosing said valve, a tubular stem, D, provided with an internal screw-thread, j, and a screw-rod, I, arranged Within the stem D,and adapted to bear against the valve B, substantially as set forth.
4. The combination, with the valve-casing A, having a cylindrical enlargement, A, and valve-seat b, of a cage, C, arranged in the enlargement A of the casing, and provided with a valve-support, a hall-valve, B, conned Within the cage C, screw-stem D, and screw- LEANDER G. GILBERT.
