REVERSE-VALVE.
Specification of Letters Patent.
Patented oet. 16,1906.i
Application led December l2, 1905. Serial No. 291.406.
I a citizen of the United States, residing at Pittsburg, in the'county of Allegheny and State of Pennsylvania, have invented or .discovered new and useful Improvements in Reverse-Valves, of which the following is a specification.
My invention relates to reverse-v alves with water seals, and has for its object toprevent the waste of gas during the time the valve is moving from one position to another.
In water-sealed valves in use with gasproducers and regenerative or other furnaces the gas from the producer is permitted to go directly to the chimney during the time the `water seal is broken by the shifting of the valve from one position to another.
It is the obj ect of the present invention to prevent this waste of gas by preventing the travel of the gas from the time the valve rises out of the water till it is again in the water. f
Among the many ways by which the 'flow of gas may be interrupted during the reversal of the gases I have chosen for illustration the one shownon the accompanying drawings, on which- Figure 1 is a side elevation of my invention With a portion broken away; Fig. 2, a horizontal section on the line II II of Fig. 1 Fig. 3, a vertical section onvthe line III III of Fig. 1; Fig. 4, an end elevation, and Fig. 5 a fragmentary view, showing in side elevation how the carriage is secured to the piston-rod of the carriage-moving piston.
On the drawings, 1 represents the valvecasing, having its lower edge supported in the Water-pan 2 below the water-line. This casing is wholly open on its lower side, but is entirely inclosed gas-tight elsewhere. At its top is the gas-inlet 3, provided With the valve 4. Through this inlet the gas from the producer enters the valve-casing.
The bottom of the water-pan 2 has three gas-ports, the central one, 5, leading to the lchimney or stack and the end ones, 6 and 7, leading to the usual furnace or other device for which the valve is adapted. The ports 5, 6, and 7 are formed by flanges which rise above the water-level in the pan.
8 re resents the gate or valve proper for reversing the flow of the gas as required in regenerative or gas-reversing furnaces. This gate is carried on wheels 9, running on tracks 10, which are preferably the lateral edges of the water-pan 2. The gate is entirely open below and has its lower edge normally below the water-level in the pan 2 and is otherwise wholly closed on the other ive surfaces. It is connected to the wheels by means of arms 11, which extend beneath the bottom of the valve-casing -1. The gate or valve 8 is sufciently long to cover the middle port 5 and one of the end ports 6 or 7 simultaneously when in its lowered or water-sealed position. f
The tracks 10 are each provided with the pairs of cams or elevations 12 and 13, up which the wheels 9 travel to lift the valve 8 out of the water, along which they travel to transfer the valve to another working position and down which they travel to lower the valve into the water seal. The valve 8 is provided with inwardly-projecting lugs 14 and 15, which coperate with pairs of lugs 16 and 17 on the outer edges of the damper or 'gate 18, which is preferablya metal-flanged plate of a size to close the central port 5 when moved thereover. The gate 18 is supported on wheels'19, running on the tracks 2() in the pan 2. The pairs of lugs 16 are shown at the left-hand end of the gate 18 and the pair 17 at the right-hand end, the lu s 14 and 15 resting between the members 0I the respective pairs. It is clear that the lugs 15 could be omitted.
21 and 22 represent a pair of pistons for moving the valve 8.
23 represents a vertical plate secured to the bar connecting the wheels 9. It is provided with a vertical slot 24, in which rides the pin 25, secured to the piston-rod working in the cylinders 21 and 22. The slot 24 allows the wheels and valve 8 to move up and down without disconnecting the valve-y moving means..
If the parts stand as shown on Fig. 2 and in full lines on Fig. 1, (the dotted line 23 representing the corresponding position of the valve 8,) the gas from the port 3 would pass into the valve-casing 1 and out therefrom through the port 7. After passing through the furnace (not shown) the spent gases go up through the port 6 into the hollow of the valve 8 and then down through the stackport 5. When it is desired to reverse the IOO Vcurately over the port 5, the wheels 9 by running up the molines of the elevated portions 12 and 13 carry the lugs 14 and 15 above and out of contact with the lugs 16 and 17. vThe valve 18 remains over the port 5 until the valve 8 has run nearly to the bottom of the inclines on the right-hand sides of the elevations 12 and 13, when the lugs 14 pass between the pairs of the lugs 17. The valve 8 moves to the right on horizontal portions of the tracks 10 till the valve 18 is moved 'from over the port 5 to aposition between the ports 5 and 7, the valve 8 then occupying the position shown by the dotted lines 24. The dotted line 25 shows the position 'of the valve 8 when the wheels are about to ride to the right and uponthe elevations 12 and 13. When the valve 8 has been moved to its extreme right-hand position, the gas then passes from the port 3 down through the port 6, up through the port 7, and down the chimneyport 5. I/Vhen the valve 8 is moved to the left, the valve 18 is `lirst moved over the port 5, when the interlocking' lugs pass by each other, leaving the valve 18 there until the wheels '9 pass down from the inclines of the elevations 12 and 13. The lugs Aagain interlock and the valve 18 is moved oil to the left from the port 5.
Having described my invention, I claim- 1. In a water-sealed valve a casing having inlet and outlet ports, a ma'in reversing-valve proper therein, normally covering said outlet, a second valve, and means for moving the latter to close the outlet before the valve breaks the water seal and to open the outlet yafter the seal is again made.
2. In a water-sealed valve a casing having inlet and outlet ports, a main reversing-valve the water seal and to open the outlet afterl the seal is again made.
3. In a water-sealed valve a casing having inlet and outlet ports, a main reversing-valve proper therein, normally covering said outlet, av second valve within the main valve, land means for moving the latter to close the outlet before the main valve breaks the water seal and'to open the outlet after the seal is again made. A
4. In a water-sealed valve a casing having inlet and outlet ports, fa main valve therein, normally covering said outlet,a second valve, interlocking connections between the main and second valves operative to move the second valve to close the 'outlet prior to the breaking of the water seal, inoperative while the main valve is out 'of the water, and again operative after the main valve is in the water 15o move the second valve Jfrom the said out- 5. In a water-sealed valve a casing having inlet and outlet ports, a main valve therein, normally covering said outlet, a second valve, a cam-track for said main valve to control its movements into and from the water, interlocking connections between the main and second valves operative to move the second valve to close the outlet prior to the breaking of the water seal, inoperative while the vmain valve is out of the water, and again operative arfter the main valve isin the water to move the second valve from the said outlet..
Signed at Pittsburg, Pennsylvania, this 8th day of December, 1905.
