Application filed May 24, 1883. (No mo'delll 'i i To all whom it may concern;

Be it known that I, J AMES E. LEADLEY, of-

Camden, in the county of Camden and State of New Jersey, hat e invented certain new and useful Improvements in Water Protected Valves; and I do hereby declare that the following is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form partof this specification.

This invention relates to a new and useful device for protecting valves in blast, gas, or

. ate theamount of flow; but it is found that they are soon rendered inoperative by the extreme heat to which they must be subjected, and often by the action of the gases at high temperatures. It is the object of myinvention to overcome or alleviate these difficulties.

To this end my invention consists in the combination of a valve and reservoir having induction and eduction pipes, and so arranged relatively to each other that by a proper supply of refrigerant both the valve and its casing are preserved; and it consists in other details, all of which will be described more par ticularly hereinafter.

In the drawings, Figure 1' is a transverse section of a valve constructed according to my invention, showing a reservoir for the refrigerant surrounding it, and means for maintaining a practically constant temperature. Fig. 2 is an elevation, partly in section, showing the valve and its case without the surrounding reservoirs. Fig. 3 is a section on line :0 m, Fig. 2.

13 represents ahollow metallicvalve, sliding in a tubular case, A, suitably secured to the conduit, and provided with bearings h h, in which slide tubes E E, communicating with the interior of the valve. These tubes E E act at the same time as the means of supplying the valve with the refrigerant from ajsuitable reservoir, and as a means of insuring accuracy in themovements of the valve. or piston F, controlling the movement-of the The rod valve, may be connected exterior-1y in any suitable manner, so as to give the valve an upward and downward movement whendesired. One of the pipes E E may receive a supply of refrigerant from a reservoir situated on a higher horizontal plane, and mayhave its discharge on a lower plane than its top.

In Fig. 1 is shown one way of carrying out my invention, whichI have found effective in securing a proper circulation of the refrigerant, and which yields good practical results. The valve and its case are surrounded by a cylindrical chamber or tank, as shown. The conduit for the gases passes through in a plane perpendicular to the face of the drawings.

a is a supply-pipe entering the tank near top, and is connected with any suitable source of supply. The refrigerant, which is water at ordinary temperature, entering near the top of the tank, is deflected downward by the diaphragm or deflecting -piece m, and discharges through pipe 0. It will thus be seen that an independent circulation is thus obtained through both valve and tank, whereby the valve and its casing are both preserved. The refrigerant in the valve is supplied from the tank, it being directed into one of the pipes E by the deflectingpiece m, and after it has become heated in the valve its specific gravity is less, and, consequently, it will either escape to the tank as steam and be condensed or be forced out of the said valve by the constant fresh supply of refrigerant to the tank. The valve may be controlled by a lever, 7:, so as to open or close the air or gas conduit to any desired degree.

dis a pipe placed near the bottom of the chamber 0, and is provided with a stop-cock, so as to draw off the refrigerant when desired.

The operation of my device will be understood from the preceding description without further amplification.

Having thus fully described my invention, what I desire to claim, and secure by Letters Patent, is-- y 1. The combination, with a hollow valve, B, and refrigerant chamber 0, surrounding the case A of said valve, of tubes connecting the valve with the chamber, substantially as and for the purpose set forth.

2. The combination, with a hollow valve, B, and the surrounding chamber 0, of the ingress and egress tubes E E, sliding in bearings in the case A, partly inclosing said valve, said tubes maintaining precision in the action of the valve, substantially as described.

r 53. The combination, with a hollow valve operated by a rod, and provided with ingress and egress tubes for the circulation of a refrigerant therethrough, and working in case A, of a tank containing said valve and refrigerant,

substantially as described.

4. The combination, with the hollow valve B, provided with the ingress and egress tubes 1* E, the rod for operating said valve, the

case A, partially inclosing said valve and in which it slides, and the chamberO, containing a refrigerant, of the induction and eduction pipes at c, for maintaining the temperature of the refrigerant, substantially as described.

5. The combination of the hollow valve B and the case A with the refrigerant-chamber 0, provided with ingress and egress pipes ac, for the supply and discharge of refrigerant, and with a deflecting-piece, m, substantially as described.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.
