Specification of Letters Patent.
Patented March 26, 1907.
Application filed August 20, 1906. Serial No. 331,318.
' fo all whom t may col/warn:
Be it known that I, FRIEDRICH WEIss, a subject of the German Emperor, residing at Riclrlingen, Germany, have invented certain new and useful Improvements Relating to Steam-Cylinder Drain-Valves, of which the following i's a specification.
This invention relates to drain-valves for the cylinders of steam and vapor engines, more particularly locomotives, in which the drain-valves are operated from a distance by Ineans of compressed air, steam, or vapor.
The invention substantially consists in constructing drain-valves and parts connected therewith in such a manner that a plurality of such valves can be operated collectively by means of a single pressure-conduit. Connecting-gear and branch pipes are thus dispensed with, and access to the bearings is facilitated.
The invention is illustrated in the annexed drawing, Figure 1 being a diagram showing the arrangement of the drain-valves of a locomotive, and Fig. 2 a section of a drain-valve adapted to be operated by means of steam or compressed air.
The valve-case b is screwed to a socket a integral with the cylinder, the outer surface of the said case being prismatic to allow of screwing and unscrewing it With the aid of a Spanner. The case t contains the valve c and valve-seat d, the valve being normally held open by a spring k when there is no pressure in the cylinder or pipe L. A duct e connects the interior of the case t to the outer atmosphere. Below the valve c is arranged a piston f, movable in the direction of the axis of the valve c and having a downward projection, below which is located a valve g for the discharge of water of condensation formed in the conduit h. The valve g is'normally kept open by a spring i. The conduit h communicates with a source of steam or compressed air which serves for operating the drainvalve. A series of drain-valves are in communication with the conduit h and are collectively controlled by means of a three-way cock y'.
The manner in which this arrangement is used is as follows: When water or steam is to be discharged from the cylinder or cylinders, boiler-steam or compressed air from the airdrum of the pneumatic brake is admitted to the conduit h. The piston f is thus caused to lift the valve c from the seat, so that steam and water can pass from the cylinder to the duct e. The pressure in the conduit h at the same time closes the valve g. When the said pressure is cut off, the pressure in the cylinder closes the valve c and interrupts communication between the cylinder and duct e, and at the same time the valve g opens to discharge water of condensation, if any, from the conduit h.
What I claim as my invention, and desire to secure by Letters Patent of the United States, is-
l. The combination with a steam-engine cylinder of a plurality of drain-valves, a pressure-piston for each drain-valve a single prestons and means for controlling the pressure in said conduit whereby the pistons are operated.
2. The combination with a cylinder drainvalve of a spring for opening it, a piston adapted to open the valve against pressure in the cylinder, a pressure-conduit leading to said piston and a spring-controlled drainvalve to said conduit, said piston and drainvalves being all axially alined substantially as set forth.
In witness whereof I have signed this specification in the presence of two witnesses.
