- OUTLET VALVE Filed June 14, 1924 Patented Nov. 19, 1929 HARRY VISSERING, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE OKAIDEE COMPANY, OF M CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS Y i OUTLET VALVE Application filed June 14,

The invention relates to'outlet valves for locomotive cylinders, and its object is to provide an improved combined blow-off cock and automatic valve by which the condensate will be drained from the cylinder whenever 1 sion hereof.

In the drawing: Fig. 1 is a diagrammatic view showing the manner in which the improved valves are connected to the steamcylinder of a locomotive. Fig. 2 is a vertical section. Fig. 3 is a section taken on line 38 of Fig. 2. Fig. 4: is a section taken on line H of Fig. 2.

The invention is exemplified in a structure comprising a'casing 'or body 5 which is connected by a threaded nipple 6 to the engine cylinder 8. An outlet port 7 formed in the cylinder is in communication through the nipple 6 with a chamber or passage 9 1n the upper portion of said casing. A valve-seat 10 is formed at the upper end of vertical outlet passage 11, which is formed in the casing 5 and leads downwardly from sa1d seat to an outlet 12 in one side of said casing. A conical cock 13 is adapted to close on seat 10 and has a pendant stem 14 having a deflector cone 15 thereon. The lower enlarged end 14 of said stem slides in a cylindrical guideway 5. A slot 16 is formed in the lower end of the stem for a slide 17 which is adapted to be manually operated to lift the cock 13 above its seat to permit the pressure from the cylinder to escape through passage 11 and outlet 12. I

A duct 18 is formed in the casing 5 and leads laterally and outwardly from the chamber 9, thence downwardly, as at 18*, and thence inwardly, as at l8 toupwardly facing outlet 20. A conical valve seat 21 for a ball valve 22 is formed adjacent the upper end of outlet 20. Valve 22 is adapted to be opened by gravity, is guided vertically by ribs 23, and is insertable into and removable from the casing through an opening 1n the bottom wall 25. A screw plug 24: threaded to the lower wall 25 of said casing closes said 1924. Serial No. 719,938.

opening. While there is steam in the cylinder, the pressure theft-5111 will keep the valve 22 closed, the minimum operating pressure being sufliclent to hold the valve 22 up against its seat 21.

The device described forms a combined blow'oif cock and drain valve. A combined cylinder cock and drain valve is connected to either end of the cylinder to blow 0H from and drain the cylinder. at both sides of the piston. The cocks 13 are con jointly operable by a slide 17 which extends through the stems 14 of both cocks respectively and is provided with a cam 27 for lifting each of said stems. The usuallink 28 to open the cylinder-cocks 18.

In practice, the cooks are opened whenever it isdesired'torelease the pressure from the cylinder, and'closed when thepressure has escaped. iTheyv are not generally left open any longer than is necessary'to blow ofi the pressure in the cylinder so that after I the valve is closedthe. condensate accumulates. In the operation of the present invention, the ball valve 22 will be held closed while there "is pressurein the cylinder 8. When the cooks 13 are'opened the pressure drops so that the ball 22 will fall by gravity onto plug 2 1- and remain.there. The @0111 densate will flowfrom the cylinder 8 through each port 7, nipple 6, chamber 9, ducts '18, 18 18", around ball 22, and. be discharged through outlet 20, as long as the cylinder rer tins out of use. Outlet20 opens into a crosschannel 26 in the casing.- Theport'ion of the casingin which the duct-I18 isformed.

I overlies the opening 20 and serves'to protect the latter againstthe entry of dirtand the like. As a result, the drain valve 22 will be open at all times except when there is pressure in the cylinder, and "the condensate, V

which forms after; blowing off the'cylinders,

will be discharged instead of accumulating combined cyl- 7 Q in a single casing'for convenience in installation and maintenance.

The invention is not to be understood as restricted to the details set forth, since these may be modified within the scope of the appended claims,without departing from the spirit and scope of the invention.

Having thus described the invention, what- I claim as new and desire to secure by Let'- ters Patent is: ,7

1. The combination with an engine cylinder, of a casing connected to receive condensate from the cylinder, having a horizontally extending duct, a blow-off cock in the casing and at one end of said duct, and a vertically movable automatic pressure controlled drain-valve in the casing, the other end of said duct extending downwardly and thence inwardly andupwardly to said valve 2. The combination with an engine cylinder, of a casing connected to receive condensate from the cylinder, a blow-off cock in said casing, an automatic pressure controlled drain-valve in said casing, an upwardly facing outlet leading from the valve, and a duct in the casing extending laterally from the cock and around and under said valve and through which the condensate will escape when the cock is closed.

3.;The combination with an en ine cylinder, of a valve casing connected to receive the discharge from the cylinder, a blow-oft cock in and at one side of said casing, an

automatic pressure controlled drain valve in said casing and adjacent one side of the cock, an upwardly facing outlet from the valve, a transverse duct in the easing into which the outlet discharges, and a duct leading laterally from thecock and around the valve to said outlet.

4. An outlet valve of the character described, comprising a-horizontally elongated casing provided at one end thereof with a nipple whereby it may be connected to the bottom of an engine cylinder to receive the condensate therefrom, a blow-off cock in said i 7 one end of the casing and disposed beneath the nipple, and avertically movable automatic pressure controlled drain valve in the other end of-theicasing, said casing having a duct leading laterally from the nipple to said drain valve, and a cross port at the discharge end of the duct into which the C011? densate fromthe valve is discharged, said cross port extending entirely through the sides of the casing.
