N PETERS PHDTCLII'NDGNAFIIER` WASHINGTON D C UNITED STATES PATENT OEEIGE.
THOMAS B. DAVIS AND SAMELS. DAVIS, OF ROOK ISLAND, ILLINOIS MPROVEM ENT IN STEAM-TRAPS.
Specification forming part of Letters Patent No. 218,941, dated August 26, 1879; application filed i July 16, 1879.
To all whom it may concern:
Beit known that we, Trios.` B. DAVIS and SAML. S. DAVIS, of Rock Island,in the county of Rock Island and State of Illinois,.have invented certain new and useful Improvements in Steam-Traps; and we do hereby declare that the following is a full, clear, and exact description of the invention, reference being had to the accompanying drawings, and to the letters of reference marked thereon, Which form part of this specification.
The nature of our invention consists in the construction and arrangement of an automatic steam-trap for ieturnin g the water from steamcoils back to the boiler whether the water-level in the boiler is higher than the coils or not, as will be hereinafter more fully set forth.
In order to enable others skilled in the art to which our invention appertains to make and use the same, we will now proceed to describe its construction and operation, referring' to the annexed drawings, in which- Figure 1 is a central vertical section of our Y trap; and Fig. 2 is a detail view of the partition C.
A represents a cast-iron chest, of any suitable dimensions, provided with a steam-tight cover, B, and an interior partition, (l, of proper height.
E is a standard in the chest, in the upper end of which is pivoted a lever, D, the long arm of said leverl being curved, as shown, and extending over the partition C, with a bucket or Wessel, F, suspended from the end. In the bottom of this vessel is a valve, a, opening upward and provided with a downwardlyprojecting stem, b, which, when the vessel descends, strikes the bottom of the chest and opens the valve a. p
From the smaller arm of the lever D is suspended a Weight, G, sufficiently heavy to overbalance the vessel F when empty.
H is the returnpipe from the reservoir, provided with a check-valve, e, and above the samev with a valve, d, the stern of which connects with the lever D, between the fulcrum of the lever and the weight G. On the opposide side of the fulcrum from this valve-stem to the lever D is connected the stein of a valve, f,which is located in the steam-pipe I from the boiler. Both the valves d and fopen downward, and their respective pipes H and I extend a suitable height in the chest A.
J is the water-pipe to the boiler, in which pipe is a check-valve, h. Thepipe J opens in the bottom of the chest on one side of the partition C. On the other side of said partition, below the vessel F, is another pipe, K, leading into the pipe J above the valve h, and said pipe K is also provided with a check-valve, i.
The partition G is provided with a flange or spout, L, at the top, which extends over the side of the vessel F.
A steam-tight reservoir is to be located below thelevel of the heating-coils and the steampipes and the condensed steam drain into this reservoir. The trap is to be set three or four feet above the level of water in the boiler.
The back-pressure, together with the vacuum formed in the trap by the condensing steam, raises the water from the reservoir up into the trap through the checkvalve e in the pipe H and the valve d, it being understood that as long as the vessel F is empty the weight G and pressure of steam on the valve f keeps the valve d openand the valve f closed until the water is sufficiently high to run over the ilan ge L on the partition C into the vessel F, and until the weight of said vessel is sufficient to overcome the pressure of steam against the valve f, whenthe vessel F will fall, which opens the valve f and closes the Valve d, shutting y oii` the water from the reservoir. '.Ihe steam rushes in through the valve f until the pressure on the trap is equal to that ou the boiler, when the weight of water in the trap will open the check-valves h i in the pipes J K from both sides of the partition G. The valve a in the bottom of the vessel F opens when said vessel descends to the bottom of trap.
The water will now run from the trap down into the boiler until it has all run out of the trap and the vessel F, when the weight Gr will overbalance the empty vessel F and raise the same and set the trap as before, and the steampressure from the boiler will close the checkvalve hin the pipe J.
In the top Bot' the trap is an automatic airvent, m, which assists in letting the pressure off the trap, and then the condensing steam,
forming a partial vacuum until the pressure on' the trap gets below the back-pressure on the 2 meen reservoir, causes the Water to rise and open the eheok-valve and ll the trap, when it will aot as before.
Having thus fully described our invention, what We claim as new, and desire to secure by LettersPatent, is-
1. In an automatirl steam-trap, the chest A, having interior partition C and pivoted lever D, one end of said lever having a vessel, F, suspended from it on one side of the partition, and the other end havinga Weight, G, and the water and steam-valves connected to it on the other side of the partition, all substantially as and for the purposes herein set forth.
2. In an automatic steam-trap, the combination of the pipe H from the reservoir, having valves el e, the steam-pipe I from the boiler, having Valvef, and the pivoted lever D with vessel F and Weight G, substantially as and for the purposes herein set forth.
3. In a steam-trap, the combination, with the ehcst A, having partition C, of the Water-pipes J K, provided, respectively, with lthe checkvalves h i, for the purpose described.
A 4. In a steam-trap, the Valve a, with stem b, in the bottom of the Vessel F, for the purpose described.
In testimony that We claim the foregoing as our own We affix our signatures in presence of two Witnesses.
