WILLIAM CURLETT, OF SAN FRANCISCO, CALIFORNIA.
SPECIFICATION forming part of' Letters Patent No. 543,128, dated July 23, 1895. Application filed November 3, 1894. Serial No. 527,797. (No model.)
To aZZ whom it may concern.-
Be it known that I, WILLIAM OURLETT, a
- citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Globe-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.
This invention relates to an improvement in globe-valves designed more particularly for garden use or irrigating purposes; and the novelty will be fully understood from the following description and claims, when taken in connection with the annexed drawings, in which- Figure l is a vertical sectional view of my improved device. Fig. 2 is a cross-sectional View taken in the plane indicated by the dotted line :20 won Fig. 1. Fig. 3 is a perspective view of the valve removed from the shell or casing, showing the parts in section; and Fig. 4 is a detail vertical sectional view of a modification.
Referring by letter to said drawings, A indicates the shell or casing, which comprises a base or lower sectiona anda top or upper section I). The base-section is of a form substantially as shown, having its lower end internally screw-tapped, and its opposite orupper end, which is enlarged, is provided with an external screw-thread c, as shown. This base-section is provided at diametrically-opposite points at its mouth or upper end with vertically-disposed guides or ways d, and at a suitable point below these guides is a narrow bridge or crossbar 6, which is provided with a central vertical aperture f, for a purpose which will presently appear.
The upper section b is provided with an aperture g at its upper end, which extends through the body for the passage of the key or spindle of the valve, and at the base of this aperture gis an annular shoulder '5, against which a packing 2" is placed. The upper section is also provided with a nozzle j, which may be externally screw-tapped, as shown at k, for the attachment of a hose or the like, and said upper section is furthermore provided with a depending valve-seat Z, which is of an annular form.
B indicates the valve. This valve is of a form better shown in Fig. 3 of the drawings, being of a circular shape in outline, and is provided at diametrically-opposite points with short arms or lugs C, which are designed to take into the ways or guides d of the lower section, seems to be truly guided in a vertical manner. This valve is preferably provided in its engaging face with an annular groove D, which is designed to receive a gasket E, so as to form a tight joint when brought against the seat Z. The valve, which is placed in the guides or ways of the base-section, is provided with a central depending stem F, which passes through the vertical aperture in the bridge or cross-bar e, and a spiral or other suitable spring G is interposed between the base of the valve and said bridge or cross-bar and su rrounds the stem F. The valve is provided in its top with 'two inclined planes H and I. The planes are pitched in opposite directions, so that the highest point of one will be diametrically opposite the highest point of the other, bringing the lowest points in similar positions with respect to each other.
J indicates the key or stem of the valve. This stem or key, which passes through the aperture 9 of the upper section, is provided at a suitable point in its length with an annular shoulder K, which is designed to contact with the shoulder 'Z of. the section b, with the packing ring or gasket interposed. The stem is provided at its upper end with a suitable handle L, which may be held in position by a screw M, taking into a screw-threaded aperture in the upper end of the stem, or other suitable means might be employed. The stem is broadened at its lower end and maybe provided with a blunt chisel-edge N to engage the cam-surfaces of the inclined planes H.
'In Fig. 1 of the drawings I have shown the parts in position with the water-way partly open. In the normal position, with the valve closed, the engaging end of the stem J is at the base of the cams or inclines H, when the force ofthe water below the valve, and also the actionof the spring aiding, will force the valve up to its seat Z, and effectively shut off the supply. To open the valve, it is simply necessary to turn the stem or key so as to ride up the inclined planes. This will force the valve down away from the seat Z, thereby allowing the water or liquid to pass up around the valve and out through the dischargenozzle, the shoulder on the stem serving to prevent any leakage through the stem-aperture of the upper section, as said shoulder always remains in contact with the shoulder t of the valve-casing, whether the water-supply has been opened or closed.
I have illustrated the cams or inclined planes as formed integral with the valve, but I am aware that a block or disk bearing the cams may be formed from a separate piece and secured in a central recess of the valve, and I am also aware that other changes and modifications might be made in some of the parts, and therefore do not wish to be understood as limiting myself to the details of construction which I have so specifically described. The upper section b of the shell or casing is also provided with an internally screw-tapped depending annular flange P, which is designed to engage the threads 0 on the lower or base section.
From the construction described it will be seen that should any of the parts become impaired or injured they can be quickly renewcd and replaced by others, access being readily had to the interior of the valve by simply screwing the two sections a and b apart.
In the modification illustrated in Fig. 4 of the drawings it will be seen that I dispense with the bridge or crossbar e and provide an internal annular shoulder e to rest a bowed spring Z, which has an aperture for the passage of the stem of the valve, and surrounding the valve-stem and bearing upon the bowed spring Z is a spiral or coiled spring G. In this modification I also dispense with the groove in the face of the valve and the gasket placed therein, and in lieu thereof I provide the ground valve-seat Z on the flange of the upper section, and I provide the valve with a double face 771., so as to tightly engage the seat 1. It will be observed that the planes H and I, both in the modification and in the main construction, have shoulders or stops Q at their highest points, so as to limit the turning movement of the stem J and prevent it from slipping off of the planes.
It is obvious that the sections of the casing may have the threads at the connecting parts dilterently disposed. For instance, the lower section may have the threads internally and the upper section have its threads externally, and suitable shoulders may be provided for washers or rings, and while I have described my invention as relating to globe-valves for garden use, it can, with slight modifications, be adapted as a steam-valve, and it can be used on faucets for various purposes.
Having described my invention, what I claim is- 1. In a valve, the combination of a shell or casing having a passage for a stem or key and also having a valve-seat, a valve having the central depression and the two inclined planes II, I, arranged in said central depression, a spring adapted to normally press and hold the valve against its seat, and the key or stem having a blunt chisel edge engaging the inclined planes of the valve, substantially as and for the purpose set forth.
2. The herein described valve comprising the shell or casing having the opposite guides or ways 01, and also having a valve seat, the valve having lugs arranged and adapted to move in the guides or ways cl, and also having a central depression and the inclined planes or cams II, I, arranged in said depression, a spring adapted to press and hold the valve against its seat, and the key or stem having a blunt chisel edge engaging the inclined planes II, I, of the valve and also having a shoulder to prevent leakage, substantially as specified.
In testimony whereof I aiiix my signature in presence of two witnesses.
