EDGAR A. WEIMER, OF LEBANON, PENNSYLVANIA.
-STEAM-ENGINE VALVE.
SPECIFICATION forming part of Letters Eatent No. 662,994, dated December 4, 1900. Application filed September 17, 1900. SerialNo. 30,296. (No model.)
To all whom it may concern:
Be it known that I, EDGAR A. WEIMER, a citizen of the United States, residing at Lebanon, in the county of Lebanon and State of Pennsylvania, have invented certain new and useful Improvements in Steam-Engine Valves; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to steam-engine valves, and has especial reference to that class known as puppet-valves and it consists in certain improvements in construction which will be fully disclosed in the following specification and claims.
In the accompanying drawings, which form part of this specification, Figure 1 represents a vertical section of an exhaust-valve embodying my invention, and Fig. 2 a side elevation of a drip-cup and a stirrup for securing the cup to the valve-chest.
Reference being bad to the drawings and the numerals thereon, 1 indicates the valvecase; 2, the removable cover; 3, the upper horizontal concentric valve-seat; 4:, the lower horizontal concentric valve-seat, and 5 the valve, which is provided with an upper spider 6 and a lower spider 7, the former having a hub 8, provided with a straight bore 9, and the latter having a hub 10, provided with a connterbore of two different diameters, as indicated at 11 and 12, and a valve-rod 13 of two different diameters, as indicated at 14C and 15, the larger diameter 14 extending through the upper spider and into the upper and enlarged part 11 of the bore of the hub 10, the lower end of which part of the bore forms a seat or shoulder for the lower end of the enlarged part 14 of the rod, and the reduced part 15 of the rod extends through the lower endof the valve-case, while the upper end of the rod extends through the upper end of the case and is provided with a stuffing-box 16 and a gland 17.
Below the hub 10 the rod 13 is surrounded by a sleeve, secured on the free end of the rod by a washer 18 and a nut 19 and ajamnut 20, and at its upper end and bearing against the lower end of the hub 10 is a nut 21, which forms a collar, between which and the lower end of the enlarged part 14 of the valve-rod the valve 5 is secured by the nuts 19 and 20. The valve-rod, with its sleeve, extends through the lower end of the valve-case and is provided with a stufling-box 22 and a gland 23.
A drip-cup 24 is suspended below the valverod by a stirrup 25, secured to the lower end of the valve-chest in any preferred manner.
The valve 5 is provided with two bearingfaces 26 and 27, as is common to this class of valves, which engage the valve- seats 3 and 4, and the valve is effectively guided to its seat by the rod passing through the upper spider therein and by the rod extending through the opposite ends of the valve-case, and the valve can be readily tightened on the valve-rod by the nuts 19 and 20, which are outside the valve case and accessible to the engineer while the valve is in motion.
It is obvious that my invention may be applied to the steam-supply valves of an engine with equal facility.
Having thus fully described my invention, what I claim is- 1. A steam-engine puppet-valve having a rod extending through the center thereof and through both ends of the valve-case, whereby the valve is guided to its seat, and means on the free end of the rod outside the case for tightening the valve on the rod.
2. A steam-engine puppet-valve having an upper and a lower bearing-face, a rod extending through the center of the valve and through opposite ends of the valve-case, concentric horizontal seats in the case engaged by the valve, whereby the valve is guided to its seat, and means on the free end of the rod outside the case for tightening the valve on the rod.
3. A steam-engine valve having an upper
