(o1. 1st-roar) 'This 'invention relates 2to yair tanks, and, more particularly, means for getting ridfof-'excessimoisture `condensation and other matter.
It is well-known that water, dirt, oil and other foreign matter -col-lect inthe bottom of air and Lgas tanks Aand should be removed because, otherwise, it will be carried through 'the pipes vto the devices that-are-operated by compressed gas, causing faulty operation and damage. YThis is particularly serious in cold 'weather when water /orother-:condensation is apt to vfreeze in airlines and prevent operation of the 'brakes, doors and other "devi'ces.
object l'of this invention is to provide means for automatically removing water or other condensation from tanks and to prevent the Vclogging "of *the lines.
nnother'object of the invention is to provide a device which will be simple in character, eicient in operation and which will require very little servicing.
Other objects and advantages of my invention will appear in the accompanying drawings in Which- Fig. 1 is a cross-sectional view of a\form of my device shown attached to an air tank.
Fig. 2 is a modification of my device shown in cross-section.
Fig. 3 is a further modification.
Referring more particularly to the drawings, and particularly to Fig. 1 thereof, there is shown a conventional air tank I together with a cleaning device, shown by the numeral I I. This device consists essentially of two castings, I4 and I5, the casting I5 having an internally threaded ange I6 to receive the casting I4. Positioned between the castings is a diaphragm I1, upon which is positioned a spring I8 which bears against the top I9 of the cavity 21|. Positioned in the casting I4 is a valve member 2|, having an upper head 22 and a lower head 23 with a reduced portion 24. A valve member 2|, and particularly the lower head 23 thereof, is a permanent magnet.
Running from the tank I 0 to the casting I5 is a pipe 30 in which is situated the valve 3|. The pipe 30 connects with the chamber 32 within the casting I5. Mounted in the chamber 32 is a screen 33 and a steel iloat 34. A passage 35 leads through the valve 36 to the atmosphere.
Liquid will drain from the tank through the pipe g 2 rises to fa predetermined lheight, the `mrngn'etired 'head '-23 will 'move downwardly toward the neat thus `:bringing the reduced portion 424 -intonregis- 'ter with'the* passage 13B., which is connected .by .means fof afpipe31to theair Vtank I0. Air will pass through the passage .35 around the :reduced portion of the 'valve through the .passage L38 to th'epipe '39, which leads 'to -the piston '46, mounted .in the :cylinder 4|. AAspring V42 normallyfkeep's the piston 'in the 'upward position, .but the Aiwi-ll lfio'rcethe piston downwardly against, th'e spring, .rotating the far-m 45, which, in turn, opens 'theyal-ve :36 `and rotates 'Ithearm f4B through the link 41 and the arm $8 lto :close the-valve 35|... This .Jal-lows the water or `other :condensate yto escape frorri fthe :chamber $2 whil'e at 4the same time preventing' vloss of air .from the tank.' :As 'the fair pressure and water fare :dischargedffrom the chamber 32 the float 34 is left without support other than the pull of the magnetized head 23. This would be insuiiicient to hold the oat against the pressure of the spring I8 bearing against the diaphragm I1 and the magnetic hold will be broken and the oat 34 will drop. The spring 2S will move the valve upwardly so that the portion 50 will contact the seat 5| to prevent passage of air through the pipe 31 and will, at the same time, move the valve 52 away from the seat 53 to allow the air in the cylinder 4I to escape through the opening 55, thus the entire apparatus returns to its normal position.
In the modification shown in Figure 2, tank I0 is provided with a pipe 69 leading to a three-way valve 6I. The valve 6I`is operated by the piston 62 in the cylinder 63 and is normally held in the position shown by means of the spring 64 about the shaft r|55 which operates the arm 66 of the valve 6|. In the position shown the valve is so set that liquid from the tank may flow down the pipe through the valve 6| and through the pipe 66 into the chamber 61 of the cleaner 19. When the level of the fluid in the chamber 61 rises the air will be forced through the passage 68 into the passage 11 under pressure and when the level of the iluid reaches a point where the magnet 1I is attracted to the steel oat 12 through the diaphragm 13 and against the tension of the spring 14, the valve 15 will unseat and allow the air under pressure to pass through the passage 11 in the block 18 past the valve 15 through the passage 19 and the pipe 80 to the cylinder 63. Of course, when the valve 15 is then seated the valve 82 automatically closes. This will push the piston to the right, closing the passage through the pipe but opening the passage from substantially identical except that different means A of operating the discharge valves are disclosed.
In the form shown in Figure 3 the principle is substantially the same and the drainage from the tank I passes through the pipe 90 through the valve 9| into the chamber-93 through the screen 94 into the chamber 95. A oat 96 with a magnet 91 operates on the member 98 through the diaphragm 99 against the spring |00. This closes the switch |0| which connects up the wires |02 and |03 to close the circuit operating the electro-magnetic switch |04. This allows the passage of air through the pipe |05 through the switch |04 through the pipe |06 to the piston |01 in the cylinder |08. The piston |01 has a shaft |09 engaging the arm H9 on the valve 9|. As the piston moves to the left it opens the drain l|| to allow the escape of the excess fluid, and, at the same time, closes the passage from the pipe 90 into the valve 9|. As the oat drops, the spring I 00 opens the switch I 0| to de-energize the magnetic switch |04 and to return the parts to their original position.
It will be appreciated that other modiiications of my invention may be made without departing from the spirit of the invention.
It will be appreciated that for the most eihcient 4 operation of my device the control mechanism should be situated below the level of the tank so that liquid will normally ow downwardly through the drain into the operating mechanism.
I claim:
A device of the character described compris-y ing a body having a chamber therein, a liquid inlet into said chamber, a valve on said inlet, a drainage outlet on said chamber and a valve for said outlet, an air cylinder on said body and a piston in said cylinder, linkage between said piston and said drainage and inlet valves whereby one of said valves is opened as the other is closed,
-an air line for said piston and a magnetic valve positioned in said line normally closing it, said magnetic valve being positioned above said liquid chamber, a magnetic float in said chamber which when raised suciently by the level of liquid in the chamber will operate upon the magnetic valve to open the air line to the piston to cause said piston to open said drainage valve and to close the liquid inlet valve.
