VALVE..
Specification of Letters Patent.
Patented Sept. 4, 1906.
Application filed VDecember 6, 1905. Serial 110,390,643.
To all whom it may concern:
Be it known that I, FRANK SGHREIDT, a citizen of the United States of America, and a resident of Mansfield, Richland county, Ohio, have invented certain new and useful Improvements in Valves, of which the following is a specification.
My invention relates to an automatic and manually-operated relief-valve.
The objects of my invention are to afford facilities for automatically operating the valve when the pressure of the steam or other substance exceeds a predetermined amount and to provide eduction-ports for its escape.
A further object is to vary the power required to actuate and release the valve from its seat automatically through the medium of spring tension.
A further feature of my invention is the means provided for relieving the pressure from the inlet-orifice manually independent of the automatic mechanism.
Another' object is to construct the body of the valve to admit of attaching an indicatorvalve with the inlet-aperture underneath the main-valve disk and which can be operated independent of the valve mechanism.
Another feature is the novel construction of the spring-case and valve-disk holder.
I attain these and other objects by the mechanism illustrated in the accompanying drawings, in which- Y Figure 1 is a cross-sectional vertical elevation taken through the center, showing the details of the construction of the valve mechanism, and cross-sectional vertical elevation of the indicator-valve, showing construction of the body of the valve to admit of attaching the indicator-valve underneath the seat of the main valve. Fig. 2 is a cross-sectional vertical elevation of the valve, taken through the line X X of Fig. 1, showing manually operated relief and drain valve. Fig. 3 is a bottom view of Fig. 1 through the line B B. Fig. 4 is a bottom view of the indicator-valve, taken through the line o o. Fig. 5 is a bottom view ofthe wheel-disk and end and top view of the stem of the indicator-valve.
Similar characters refer to similar parts throughout the several views.
Referring to the drawings, reference-figure 1 designates the body of the valve, and figure 2 the main-valve chamber. A tubular portion 3 is preferably made integral with the bottom of the valve, with one end 4 projecting upwardly into the valve-chamber and the opposite end 5 depending below the bottom of the valve-body. The .end 4 adjacent to the inner periphery is inclined, forming a valve-seat 6. A projecting portion 7 extends upward from the body, with the end terminating in an annular rib 8, having an annular inwardly-extending incline formed thereon. A valve-case 10, having its lower end 11 exteriorly screw-threaded, is adapted to engage with the screw-threaded interior 12 of the projecting portion 7 for the purpose of adjustment of the valve-case.
An annular inwardly-extending fiange 13 is made integral with the lower end of the valve-case and surrounds the tubular valvestem 14, which is secured or made integral with the valve-disk 15. Depending wings 16 are fitted to the inner periphery of the tubular portion 3, which, in conjunction with the annular flange 13, serve to keep and guide the valve in perfect alinement with the valveseat 6 when it is actuated by excess pressure counteracting the tension of a spiral spring, which Will be described hereinafter. A spira spring 17, having plugs 18 and 19, is fitted to l*the apertures of the spring and compressed and inclosed within the spring-case and tubular valve-stem.'
The spring-case is connected to the projecting. portion of the valve by my threadconcealing lock-nut A', which is the subjectmatter of a pending application filed November 27, 1905, Serial No. 289,171. The spiral spring is compressed by means of adjusting the spring-case by the engagement of the screw-threads. A screw-threaded aperture 2O is formed integral with the body of the valve-chamber, with the aperture 21 located beneath the valve-disk l5 and in coinmunication with the tubular portion 3. The aperture 21 permits the steam or other substance to communicate with the indicatorvalve, which is preferably made angular in form, as shown in the drawings, (see Fig. 1,) and connected to the main valve by the threaded interior of the end 22 of the anguas follows.
A stein 23, having an enlarged portion 24 with a threaded exterior, is received within the threaded aperture 25, which provides a means of opening or closing the valve 26 IOO lar valve. The angular valve is constructed when the stem is turned inthe ordinary manner. The end 27 is preferably formed to correspond with that shown in Fig. 5, and a disk 28 is iitted thereto. To prevent the escape of steam, a stuiiing-box 29 is fitted to the end 30 of the indicator-valve and packed in the usual manner.
It will be observed that the lpeculiar con-` struction`of the body-valve and other details admits of the steam being conducted directly into the aperture 21 independent of the automatic mechanism and Without communicating with'the main-valve chamber 2. An aperture 31 is formed in the tubular portion 4 and positioned at right angles with the aperture 20, which is adapted to receive the end of the indicator-valve, as described. The end 32 ofthe aperture is inclined to form a valve-seat. In direct alinement with the valve-seat 32 an enlarged screw-'threaded aperture 33 is provided to receive an exteriorly and interiorly screw-threaded bushing 34, which is provided with a jam-nut 35. A valve-stem 36, having an enlarged exteriorlythreaded lower portion 37, is received within the threaded interiorl of the bushing 34, which when turned by the Wheel 38 moves the valve-disk 39 in and out of contact with the seat 40, opening and closing the valve at the will of the operator, providing a means of manually relieving the ressure independent of the automatic mechanism. A stuiiingbox 41 is fitted to the end 42 of the valve to prevent the escape of steam or other substance and packed around the stem in the usual manner. The wheel 38 is fitted to a disk 43 Aand held in place by the pins 44 and the screw 45 and washer 46. Notches C are cut the wings, coinciding with the inletapertures 21 and 31 to permit the passage of the steam without retarding it in case the wings should be4 turned in direct alinement with theapertures.
