SEPARATING-TRAP.

Specification of Letters Patent.

Patented Dec. 19, 1916.

Application filed December 28, 1915. Serial No. 69,019.

To all whom it may concern:

Be it known that 1, JOHN W. NEWMAN, a citizen of the United States of America, residing at Ridgefield Park, Bergen county, New Jersey have invented a new and useful Separating-Trap, of which the following is a specification.

My invention relates to devices termed separating traps and in the present instance, I have shown and described my in vention as applied to steam and water separation. v

The object of the invention is to permit condensation to be drawn out of a steam line without allowing the pressure in said steam line to drop.

In the drawings: Figure 1 is a plan view of my invention. Fig.2 is a side elevation thereof. Fig. 3 is a relatively enlarged sectional view on the line 33 of Fig. 1 showing certain parts in elevation. Figs. 4: and 5 are detail views.

1 represents conventionally a steam chamber wlthin which condensation is liable to occur. The problem is to separate, or draw off, the water of condensation without permitting the steam pressure to drop. This I accomplish by the following instrumentality :'22 are main supporting blocks upon which is tiltably mounted my improved mechanism which operates after the manner of a walking beam. 3 represents the walking beam proper which is mounted on the supports 22 in the manner hereinafter described. i5 are tanks suitably mounted on the walking beam 3 at opposite sides of the fulcrum therefor, the fulcrum being so located relatively to the combined weight of the apparatus carried by the walking beam, that the end bearing the tank 1 will normally overbalance the opposite end carrying the tank 5. The walking beam 3 is mounted directly upon a saddle block 6 (Fig. 3) which has at opposite sides tubular extensions 78 securely fastened thereto. At the ends of these tubular extensions are packing boxes 910, respectively. These tubular extensions have suitably formed bearings which rest upon the supporting blocks 22, which latter are formed so as to provide bearing boxes 1l11 which may, if desired, be provided with anti-friction devices to permit the walking beam 3 to oscillate more freely. These tubular extensions 7-8 operate, in eifect, as hollow trunn na and bl is start the a i u water connections with the two tanks respectively without the use of flexible tubing.

I will now describe the piping. A pipe 12 leads down from the chamber to be drained to a back check-valve 13, thence on through pipe 14: through the stufling box 9, and into the chamber 15 within the trunnion 7. By preference the inner part of this pipe 14 has a bearing shoulder 16 which bears with reasonable snugness against an internal shoulder on the trunnion shown adjacent thereto. 17 is a spring which serves to keep the shoulder 16 in engagement with the internal shoulder on the trunnion. 18

is an outlet at the inner end of the pipe 14 which opens into the chamber 15. Proceeding from the trunnion 7 and in communication with the chamber 15 is a pipe 19 which leads into the tank 4 and terminates near the upper part thereof. 20 is an outlet pipe leading from the bottom of the tank 1 across to and into the tank 5 and terminating near the upper part thereof. 21 is a pipe which leads from the bottom of the tank 5 into the trunnion 8 so as to be in communication with the chamber 22 thereon. 23 is a pipe which enters the chamber 22 in the same manner as the pipe 14 enters the chamber 15. This pipe 23 has an opening 24 through which water may flow into the pipe 23. The pipe 23 leads outwardly through the stufling box 10 and communicates with a discharge pipe 25 in which is located a valve 26 and beyond the valve 26 is a check-valve 27. The valve 26 is connected in any suitable way as by an arm 28 with part of the tilting mechanism so that when the walking beam stands in the position shown in Fig. 2 the valve 26 will be open, whereas when the walking beam is tilted to the opposite position, the arm 28 will descend and the valve 26 will be shut. Any suitable valve closing means may be provided, as for example, a gravity closer weight 29. 3030 are vents in the upper parts of the tanks l5. 31 is a post which limits the descent of the walking beam 5. at one end while 32 is a post which limits the descent of the walking beam at the other end.

Having now described the various parts of the construction, its operation will be seen to be as follows: I first block up that end of the walking beam supporting the tank 4 so that the opposite end will rest upon the post 32 and the valve will b6 closed, I then open the vents in the tanks until the water of condensation will fill both tanks. I then shut the vents and take out the block, after which the trap will work automatically as follows: Upon the taking out of the block the tank 4 will descend, by reason of the fact that it will then overbalance the opposite end of the tilting mechanism. This movement will open the valve 26 whereupon the water in tank 5 will commence to flow out. It is preferable that the capacity of the pipe should be such that the water will not flow out at a more rapid rate than it can flow into the tank 5 from the tank 4. Now, as the water flows out of tank 5, it will tend to create a partial vacuum which tends to draw the water from the bottom of tank l. So far as there is any pressure in tank 4, this pressure will also tend to assist in the flow of the water from the tank 4: into the tank 5 through pipe 20, so as to supply the opposite end of the tilting mechanism, the

beam 5 will tilt back to the position inclicated in Fig. 2 and the emptying process will again take place. By this means, after the trap is once started, it will automatically tilt to and fro so as to periodically discharge the water of condensation without allowing the steam pressure to lower. Obviously the check valves 13 27 may not be employed in all cases, for example, where there is no tendency to back pressure, but when there is tendency to back pressure such check valves are desirable. In some cases it may be necessary to use high pressure steam for forcing the discharge from the trap to a boiler or to an elevated tank which will be understood by those familiar with this art. In such case, the high pressure steam will be admitted at the same time that the outlet valve is opened and closed when the outlet valve is closed.

In the preferred construction, such as I have employed with marked success, I have observed the following proportions in the use of tanks with approximately fifteen and a quarter gallons capacity each. The introductory pipe let is one inch in diameter, the connecting pipe 20 an inch and a half in diameter, and the discharge pipe 25 a half an inch in diameter. It is also desirable to have the bearing shoulder 16 and its cooperating shoulder, as provided on each of close to the trunnions 78 to prevent said pipes from turning, in which event, I provide the holding pedestals 3333.
