To all whom t may concern.-

Be it known that I, NIVENMOOONNELL, of Donora, in the county of Washington and State of Pennsylvania, have invented a new and useful Water-Cooled Valve, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in whiching a reversing-valve constructed in accord'- ance with my invention. Fig. 2 is a fronty elevation of the same on a smaller scale. Fig. 3 is a horizontal cross-section; and Fig. l is a top plan view on a smaller scale, partly broken away.

My invention relates to the class of Watercooled valves, more especially to reversingvalves for regenerative furnaces; and its object is to provide a simple, cheap, and effective valve Whichwill be long-lived and not liable to get out of order.

The invention consists in providing a cylindrical hollow valve which is constantly connected a tone end with the regenerator or other port and which is provided with a port opening through its side,which may be turned to connect with either of two side ports, such as the inlet-port and the stack-port.

The invention also consists of an oscillating valve in the form of a water-cooled shell, in providing water-cooled valve-seats`therefor, and generally in the construction and arrangement of the parts, as hereinafter more fully described and claimed.

In the drawings, in which I show my invention as applied to a regenerative reversingvalve, 2 represents a cylindrical valve-casing, through which extend the side ports 3 4, one of which leads to the stack and the other is an air or gas inlet. The shell of the casing is thickened around the ports 3 and 4, and in these thickened portions-of the casing are cast Water-circulating pipes 5 5, one of which extends around each port. Within this valvecasing lits the valve, which consists of a hollow double-Walled shell 6, having a side port 7 extending through it and corresponding to the ports 3 and 4. The valve is preferably lined with refractory material 8, which extends over its sides and within its top, the valve being open at its lower end to constantly connect with the regenerator-port 9, which leads through the bottorn of the casing. The port 9 is preferably formed by a flange within the valvecasing, leaving an annular space 10 between it and the casingshell, in which water is provided to form a seal. A ange 1l depends from the valve and enters the water in thisannnlar space, thus sealing the lower end of the valve. The upper end of thev valve is provided with an outwardly-projecting and depending iange 12, which projects down into the water in the annularchamber 13,formed bythe onteriange 14, which may be cast integrally with the casing-shell. I have shown the flange 12 as cast integrally with the valve, the annular coolingspace in which valve is open at the top and is connected with the space 13 by overliow-pipes 15. The valve is secured to a top spider consisting of I-beam sections 16, extending radially and secured together at the center, their outer ends being secured to brackets o'r castings 17, containing bearings for flanged rollers 18, Which travel upon the rim of iiange 14 on the casing. The valve thus hangs from the spider, and it may. be turned or oscillated by turning the spider by a hand-lever or other desirable mechanism. In order to hold the valve tightly against its seats and at the same time reduce the friction in turning it, I preferably cut away the inner wall of the casing to leave a very small space between it and the outer Wall of the valve-shell, except at the seats surrounding the side ports, and to force the valve against these seat portions I provide the shell with a vertical inner recess containing a loose bar 19, which is forced against the valve-shell by set-screws 20, extending through the valve-casing. By adj usting these screws the valve-shell may be held neatly to its seat, While at the same time it can be easily turned to connect the lower regenerative port either with the inlet-port or the stack-port. Water may be supplied to the cavityA of the valve by pipe directed into the top of this space, the pipe being so located that it will discharge water into the valve-cavity in any position, the turning movement being only one-quarter of the revolution. Water is led into and out of the lower sealing-space of the casing by the usual inlet and outlet pipes.

The advantages of myinvention result from IOO the simplicity of construction, the small number of parts, and preventing leakage ot' the gas to the stack-port. It will also be noted that the gas cannot escape even if it passes between the seat and the valve, as itis trapped by the water seals at the top and bottom. The water-cooling system prevents warping and cracking 0E the metal parts, and the system is easily operated and long-lived.

Many variations may be made in the form and arrangement of the valve, the casing, and ports without departing from my invention.

I claim- 1. A regenerative reversing-valve,compris ing a cylindrical casing having a port at one end, and provided with a plurality of ports extending through its side, and a turningvalve within the casing having a passage extending through it and in constant communication with the end port of the casing, said valve having a side port arranged to register with either of the side ports of the casing; substantially as described.

2. A regenerative reversing-valve comprising a cylindrical casing having an end port and side ports, and a hollow water-cooled valve arranged to turn within the casing, said valve having a passage through itin constant communication with the end port, and having a side port arranged to register with the diierent side ports of the casing; substantially as described.

3. A regenerative reversing-valve comprising a cylindrical casing having an end port and side ports, a water-cooled valve arranged to turn within the casing, said valve being hollow with one end closed and the other in constant communication with the casing end port, said valve having a side port extending through it; substantially as described.

4. A water-cooled valve comprising acylindrical casing, a water-cooled valve arranged to turn therein, and water-sealing devices for the upper and lower ends of said Valve; substantially as described.

5. A reversing-valve comprising a casing having upper and lower annular water-chambers, a water-cooled valve arranged to turn in the casing, and having depending anges within the water-chambers of the casing, the valve and casing having side ports and end ports; substantially as described.

6. A reversing-valve comprising a cylindrical casing having a bottom end port and side ports, a rotary carrier above the casing and a depending valve supported on the carrier said valve comprising a hollow shell within the casing having a lower end port; and a side port; substantially as described.

7. Aregenerative reversing-valve,compris ing a cylindrical casing having an end port and a plurality of side ports, a water-cooled turning-valve within the casing having a passage extending through it and in constant communication with the end port, said valve having a side port arranged to register with either of the side ports of the casing, and an adjusting device arranged to adj ust the valve laterally against it-s seat; substantially as described.

8. A reversing-valve comprising a cylindrical casing, having a. lower end port and a water seal, and water-cooled side ports, and a water-cooled valve consisting of a hollow shell arranged to turn within the casing, said valve having a lower end port, and a side port extending through it; substantially as described.

9. A reversing-valve comprising a cylindrical casing having two water-'cooled side ports, a water-cooled valve arranged to turn therein, and consisting of a hollow watercooled shell with a lower end port and side port, and an adjusting device arranged to adjust the valve laterally against its seat; substantially as described.

In testimony whereof I have hereunto set my hand.
