HIGH OR LOW WATER ALARM.
SPECIFICATION forming part of Letters Patent N 0. 671,017, dated April 2, 1901..
Application filed June 25, 1900.
T0 at 1071,0711, it may concern:
Be it known that I, LEWIS W. GIBSON, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Higher Low Water Alarms; andI declare the following to be a full, clear, and exact description Jf the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.
My invention consists of new and useful improvements in a water-alarm for steamboilers; and it consists of the construction, combination, and arrangement of devices hereinafter specified and claimed, and illustrated in the accompanying drawings, in which- Figure l is a view in side elevation, showing parts broken away, of my invention as applied to a boiler. Fig. 2 is a view in vertical section through the alarm mechanism. Fig. 3 is a vertical section on the line 3 3, Fig.
2. Fig. 4 is a view in horizontal section 011 the-line 4 4, Fig. 3.
More particularly my invention relates to a water-alarm for steam-boilers in which a float-actuated valve operates to control the passage of steam to a steam-whistle, whereby an alarm or signal may be sounded.
One object of my invention is to provide a simple, reliable, and efficient alarm for steamboilers adapted to inform the attendant at all times of the danger from low water or to warn him of a too-abundant supply, and thereby enable him to maintain a water-level of desired uniformity, thus securing all of the advantages possibleviz., dry steam, economy in the consumption of fuel, and freedom from danger resulting from burned or overheated boilers.
Another object of my invention is to provide a water-alarm for steam-boilers adapted to be secured therein with its vital Working parts-the valve-seat, the valve-stein, and the guides-at the highest possible point above the water-level, securing freedom from interference or deterioration by mineral deposits or other accumulations, and to provide positive means of alinement and durability to the valve and valve-stem, the device having a Serial No. 21,526. (No model.)
wide range of adjustment for high and low water levels.
I carry out my invention as follows:
In the drawings, (t represents a valve-case having a screw-threaded engagement within the boiler-shell b, thevalve-case being firmly and detachably secured in said shell. I prefer that the inner portion of the valve'case shall be provided with a flange, as indicated at c, by which a wrench may be engaged therewith. At its upperend the caseis formed with a valve-seat, as at d. Below the flange c are depending arms 6 (2. Within the valvecase is a valve f, arranged to seat upon the seat d, a stem of the valve projecting downward between the arms c e, as shown, and provided with a spring g, arranged to normally seat the valve. The stem of the valve is shown provided intermediate its ends with a pin it, engaging one end of the spring, the other end of the spring being supported upon a cross-piece 11, connecting the two arms 6 c. The stem of the valve passes through said cross-piece and through a diaphragmj above the arms e c, said diaphragm being preferably provided with ports, (indicated at 70,) through which steam mayenter into the chamber Z within the valve-case. The valve-stem may also be cut away or fluted adjacent to said diaphragm, as indicated at m. Fulcrumed at the lower ends of the arms e e is an oscillatory yoke, (indicated at 'n.,) a fulcrum-pin 13 passing through the lower ends of said arms, as shown. The extremities of the yoke n are constructed to receive a rod q, carrying a float r at its lower end. Said rod may have a threaded connection in the extremities of said yoke or be otherwise connected therewith, as may be desired. By constructing each end of the yoke to receive the rod greater convenience will be secured in locating the alarm device and the float to operate the same within the boiler.
The pin h preferably projects into elongated guide-slots (indicated at s) in the arms 6 e.
Above the pin h is a saddle t, with the extremities of which are engaged rods to '0. Said rods engage at their opposite ends through the yoke 11, nuts to being located on the outer ends of said rods. The saddle i has a yielding movement upon the valve-stem. It will be obvious that when the float rises the end of the yoke 77, with which the rod q is engaged will be tilted upward, causing the opposite end of the yoke to exert a pull downward on the corresponding rod, connecting the yoke with the saddle t. The float being connected, as shown, with the end of the yoke adjacent to the rod o, it will be evident that when the float rises a strain will be exerted upon the rod to to pull down the adjacent end of the saddle, the saddle forcing the valve f downward therewith and away from its seat, permitting steam to pass from the chamberl through the seat of the valve, with a whistle mechanism m located upon the upper end of the valve-case. On the other hand, should the float be depressed it will be evident that it will exert a downward pull upon the adjacent arm n, depressing the adjacent end of the saddle and carrying with it the valve, so as to unseat the valve and permit the alarm to sound. It will be apparent thus that whether the water rises or falls above a desired level the alarm will be sounded. As specified, the rod q may, if desired, be engaged with the opposite end of the yoke.
The rods 10 o are pivot-ally engaged with the saddle t, as indicated by the numerals 1 and 2. The opposite ends of said rods are preferably threaded, so that the nuts w may be adjusted thereon to adjust the movement of the yoke n as may be desired. It will be understood that a steam space or chamber is provided within the valve-case, (indicated at 3,) with which the ports is k communicate, and the openings m m, caused by fluting or recessing the valve-stem. It will also be observed that the valve-seat is outside of the boiler and is thus removed from the water in the boiler, as above described.
What I claim as my invention is 1. In a water-alarm for steam-boilers, the combination with a valve-case and its valve, of an alarm, a float, and a yoke fulcrumed intermediate of its ends to the valve-case, a float connected with said yoke, and a saddle engaging the valve and connected with said yoke to actuate the valve either at high or at low water in the boiler.
2. In a water-alarm for steam-boilers, the combination with a valve-case and its valve, of an alarm, a float, an oscillatory yoke connected with the float, and a saddle engaging the valve and connected with the yoke to actuate the valve either at high or at low water in the boiler.
3. In a water-alarm for steam-boilers, the
combination with a valve-case and its valve, of a saddle engaging the valve, an alarm, an oscillatory yoke connected with said saddle to actuate the valve either at high or at low water in the alarm, a float, and a rod connecting the float with said yoke, said yoke constructed to receive the said rod at either end of the yoke.
4. In a water-alarm for steam-boilers, the combination with a valve-case constructed to be engaged with the shell of the boiler and provided with depending arms, of a valve to seat in said case, a yoke fulcrumed intermediate its ends to said arms, a float connected with one extremity of said yoke, and saddle engaging said valve with said yoke.
5. In a water-alarm for steam-boilers, the combination of a valve and its case, an alarm, a float, an oscillatory yoke fulcrnmed intermediate of its ends to the valve-case connected with the float, and saddle connecting the yoke with the valve to open the valve, and means to return the valve to normalposition.
6. In a water-alarm for steam-boilers, the combination of a valve-case,a spri ng-actuated valve to seat in said case, a float, an oscillatory yoke connected with the float, a saddle engaging the valve, and arms connecting the saddle with the yoke.
7. In a water-alarm for steam-boilers, the combination with a valve-case open to the admission of steam thereinto, of a whistle communicable with the interior of the valvecase to control said communication, a float, an oscillatory yoke connected with the float, a saddle engaging the valve, arms connecting the saddle with the yoke, and means to return the valve to normal position.
8. In a water-alarm for steam-boilers, the combination with a boiler-shell, of a valvecase projecting through the shell and provided with a valve-seat, a valve to seat within said case, an alarm device engaged with the outer end of the valve-case, a float, an oscillatory yoke connected with the float, a saddle engaging the valve, and arms connecting the saddle with the yoke, said valve-seat located outside the boiler-shell.
In testimony whereof I sign this specification in the presence of two witnesses.
LEWIS W. GIBSON.
