JFECIFCATION forming part of Letters Patent No, 304,204, dated August 26, 1884.
Application filed January 9, 1884 (No model.)
.To all whom, it may conce/itz Be it known that I, WILLIAM Krisen, a citizen ofthe United States, residing at Wilkes- Barr, in the county of Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in Hydrants, of which -the following is a specilication.
This invention has reference to valve mechanism for hydrants, and embraces certain iniprovements in that class of hydrant to which my Letters Patent of the United States N o. 284,021, dated August 28, 1883, relate.
The present invention will lirst be described, and then designated in the claims.
Referring to the drawings which illustrate the invention, Figure l is a vertical section of a hydrant illust-rating a portion of my improvements, the valve being shown closed. Fig. 2 is a vertical section of the valve mechanism only, illustrating some additional features, and also showing` the valve closed. Fig. 3 is a cross-section on the horizontal line x m, showing the circumferential waste-water channel w. (Seen in both Figs. l and 2.) Fig. 4 is a cross-section on the horizontal line y y, Fig. 2. Fig. 5 is an exterior View of the valvecase shown in Fig. 2.
The hydrantstoek A, cap B, the construction of the upper parts, and pipe F are the same as shown in my patent above referred to 5 but they may be of any suitable construction.
Gast integral with the valve-case U is an interior downward-projecting rim, c, which isbored oriinish ed round in a vertical direction, (indicated by cl,) and the movable water-way L is exteriorly inished at c, forming a shoulder to t close and yet move easily within the said bored part d. Below the close-fitting shoulder ve the water-way has an exterior washer, q, to
iill the bored vertica-l part d, and between the said close-fitting shoulder and the washeris an exterior circumferential groove or depression which forms the wastewater channel w, for the escape of water from pipe F after the valve has been closed. The downwardprojecting rim chas one or more perforations, a, which allow the waste water tovrise into the circumferential channel, and the bored vertical part of the valvecase above the said rim has onea or more perforations, a, through which the waste water escapes from the channel.
My arrangement ofthe circumferential channel w and two or more small waste-water perforations, a, affords a desired advantagenamely, two or more .perforations are preferable to only one, (as employed in my patent before referred to,) because if several are only one is used, and being smaller, the washer 1 will close them much sooner when the waterway is raised to open the supply-valve5 and, again, these waste-water perforations will remain closed longer during the lowering move ment of the water-way to close the supplyvalve. Therefore by this arrangement there will be less waste of water direct from the supply-pipe during the interval occupied by raising or lowering the supply-valve.
p The perforations a in the downward-projecting rim c are made by forming bosses f on the exterior of the valve-case, then boring through each boss, and also through said rim 0,' thereby making the perforation a, and finally closing the bore in the valve-case by means of a plug or solder, or both. At the top of the bored vertical part d the valve-case flares internally, or gradually widens, as at g, whereby the movable water-way may readily be inserted after it has been withdrawn. A wastehole, h, is made in the case at this part.
rlhe construction shown in Figs. 2, 4, and 5 is contrived to permit the valve-seat t to be removed with the entire valve mechanism from the stock, in order to grind the seat whenever it may need it. i
By-reference to Fig. 2 it will be seen the rim c, washer q, perforation a, circumferential channel w, and supply-valve t are the same as shown in Fig. 1.
In providing for the removal of the valveseat, the stock A must be attached to a bottom cap or coupling, I, instead of tothe valveease U, as shown in Fig. l. This bottom cap has a screw-thread, t', into which the nipple 1J on the lowermost part of the valve-case couples. It also has below another screw-thread, o', for attachment to a service-pipe or other source of supply. Perforations j are madein the bottom to allow water to escape. By this arrangement the entire valve-case U, including the valve-seat t, may be removed from the stock by unscrewing the nipple f1) where it couples with the screw-thread To enable this to be used they may be much smaller than where' IOO done, and to also allow for the vertical movement of the water-way L, the upperpart of the Valvecase is provided with two vertical slots, 7.1, placed diametrically opposite each other, and the water-way L has two lateral. lugs, m, cast integral there\vith,which occupy the slots and slide vertically therein whenever the water-way is raised or lowered. The top end of the valve-case is screw-threaded, andan annular cap, o, is attached thereto. rlhis prevents the water-way when moved vertically from lifting out of the valve-case, and also enables the valve-case tobe withdrawn. It is obvious that other means than the annular cap may be used to serve this purpose. The opening in the annular cap allows the discharge-pipe F room to move up and down freely.
It will be seen that the slots 7c in the case and thelugs m on the waterway allow the necessary vertical movement to the supply-valve, and at the same time by turning the upper end of the discharge-pipe the valve-case, including' the valve-seat,` may be unscrewed from the bottom cap, I, and removed without disturbing the stock.
Having described my invention, I claim and desire to secure by Letters Patent of the United Statesl. In a hydrant, the valve-case U, having a bored vertical part, d, and an interior downward-projecting rim, c, provided with a perl-oration, n, and a perforation, n,in the case above the said rim, in combination with a movable water-way, L, fitted within the bored vertical part, and having a circumferential waste-water channel, w, adapted, when the valve is closed, to embrace both said lower and upper perforations, whereby the waste Water from the disa movable water-way with a valve-washer, t, l
at its lower extremity to rest cn the valveseat, means, substantially as described7 for connecting the movable water-way with the said valve-ease, which will allow the necessary vertical movement of the water-way without allowing either of said parts to turn independently of the other, and a supply bottom cap, I, to which the screw-nipple couples, whereby the water-way, valve, and valve-seat may all be removed to repair the parts or re- 'grind the seat, as set forth.
3. In ahydrant, the valvc-case U, having at its upper part vertical slots 7c and at its lower part a valve-seat, with means below the valveseat for coupling, and amovable water-Way, L, provided with exteriorlateral lugs, m, to slide in the vertical slots, and means to prevent the way from lifting out of the valve-ease, as set forth.
In testimony whereof I affix my signature in presence of two witnesses.
