ro ment in Steam-Traps; and I do hereby declare the following to be a full and exact description thereof, reference being had to the accompanying drawings, making part of this speciiication.
My invention relates to steam-traps; and it has for its object the improvement in the construction of such devices whereby theyy are simplified and rendered more efficient in action.
The novelty of my invention consists in the combination and subcombination of the parts, as will be hereinafter set forth, and specifically pointed out in the claim.
Figure 1 is a top view of my steam-trap. Fig. 3 is a section on line 3 3'of Fig. 2. Fig. 4 is a vertical section through a portion of the top of bucket-guide.
In the drawings, A represents the body of 3o the trap, and B the piston-valve. The body of the trap consists of a cylindrical boX having a solid bottom b and a removable top b2. The top b2 is secured by bolts b3 to the body A.
At the side of the body, near the top, is a 3 5 screw-thread opening b4 to receive a steampipe. Directly opposite to the opening b4 is a threaded opening b5 to receive the drainpipe. ,Within the body A is a bucket C, which is free, so that it can be raised or 4o lowered by the action of the water which will accumulate in the body A. The bucket C is provided with a guide C2, which slides up and down in the pipe b, projecting downwardly from the center of the top b2. The upper end rovided with a sliding valveface C, which c oses the hole e, that passes through the stem c2, said stem being provided with a valve-seat e4 at its lower end. The stem e2 extends down from the piston E, that plays in the cylinder F. The piston E has a small opening E2 to relieve the pressure of water on the piston E. The pressure can also be relieved by the piston E being made to play loosely in the cylinder F. The cylinder F is attached to the cap b2 by the threaded portion f. The cylinder F is also `provided with a cap f2, which screws onto the top of the cylinder F, making it perfectly tight. Attached to the lower end of the stem e2 is a valve-face e4, which closes the lower part of the cylinder F by seating on the valve-seat f3. The to b2 has a passage-way bs, which leads from the chamber where the bucket C is to the outlet-opening b5 throu h the openings f 4, which are in the cylinder A threaded stem G, provided with a stuflingboX, passes through the top of the cap f2. This stem G is for forcing down the piston E at any time, so that the trap can be blown out and emptied should occasion require it. The valve-face C3 is screwed into the sliding piece C4, which slides up and down in the sleeve C5, it in turn being screwed into the guide C2. The object in having C4 slide u and down in C2 is to prevent valve-face 3 from sticking, which is attained as follows: When the bucket C drops, it falls until the upper part of C2 strikes the loWer part of C4, the blow struck assuring the dropping of the valve-face C3, thereby preventing any sticking of the valve-face C3.
The advantage in my trap over other traps of this class is that an immense volume of water can be taken care of Without loss of steam, the passage-way between the bucketchamber and outlet being controlled by the pressure of water.
The operation of my steam-trap is as follows: The water from the condensed steam in the pipes entering the body of the trap through the inlet b4 gradually raises the bucket C until the valve-face C3 strikes the valve-seat c3, closing the hole c in the stem e2, .also forcing the valve-face e4 up against the valve-seat f3, thereby closing off all communicationbetween the chamber Where the bucket C is and the passa e-way bs, which leads to the outlet b5. As t ere is no outlet for the water, it will continue to rise in the chamber where the bucket C is and overflow into the bucket C. This will continue until the bucket C becomes heavy enough to sink, when it will open the valve which closes the bottom of the tube e2. Water will then flow through the hole e (the pressure of steam forcing it up) to the top of the piston E, which being of a greater area than the valveface c4 will be forced down, permitting the water in the bucket C to flow up through the ipe be, entering at the bottom and passing out through the opening bs to the drain-pipe opening b5. When the bucket has become IOC areas, means for passing pressure from small area to large area, means for automatically relieving pressure on large area, outlet for I5 Water through same pipe through Which bucket-guide passes, means for opening valve horn the outside of trap, all substantially as described.
