1 Claim.

This invention relates to a system and apparatus for chlorinating water supplies.

The object of this invention is to provide an automatic system of controlling the supply of hypochlorite to the water to be treated; de-

pending on the amount of water or pressure in the supply tank.

A further object of this invention is to provide a system of chlorinating water supplies'by automatically cutting off the system when the supply of hypochlorite falls below a predetermined amount and causing an alarm or other signal to be given if any more of the hypochlorite is removed from the tank.

A further object of this invention is to provide a system of chlorinating water supplies by passing the chlorine solution through a controlled valve and a filter with a. measuring drip valve into a pump and so arranged that the controlling valve is in operation only when the pump is in action.

These and other objects of the invention will be apparent to those skilled in the art from the following description taken in connection with the accompanying drawing. It is expressly un-- derstood, however, that the drawing is for the purpose or illustration only and is not designed as a definition of the limits of the invention; reference being had for this purpose to the appended claim Referring to the drawing:

, i is a complete layout of the system.

'. 2 is a detail of the hypochlorite control a oi alarn'i.

a Fig. 3 is a top view of the measuring valve.

the drawing, the pump iii, which may be either of the reciprocating or rotary type, is connected to vater through a suction. pipe ii, from a tank or from any other available source oi supply. The pump is operated by a motor is, the current for which is supplied by lines M, it.

To purify the water drawn from the tank 62, the following arrangement has been devised.

A. tanls 55, made of hard rubber or other material resistant against the chemicals used, is filled with hypochlorite or other sterilizing compound. The tank i8, is provided with a drain cock El, and a pipe iii, with a stop valve it, in the pipe line. A controlling valve 20, of the solenoid type is set in the pipe !8, with the current lines it, 522 drawn from lines l4, l5.

The pipe line it, then enters a drip valve 28, which comprises a casing 24, provided with an opening 25, at the botom thereof. A thick slab 25 with an opening at the center is placed on me inside of the bottom of the casing 24 with the openings in alignment. A vertical stem 25, which is threaded at the top 21, in threaded relation with the top of the casing 21, and is arranged to travel up or down by revolving said stem. The stem is provided with a pointer 28, at the top, which faces .a dial 29, on which numbers are exposed. By turning the stem 26, in one direction allows the opening 25, to be uncovered. The amount of opening is indicated by the number on the dial 29.

A filter 3B is set within the casing .24 around the slab 25', to withhold any impurities before 1 the solution reaches the opening 25. The purpose of the slab 25 is to provide an obstruction or dam so that the impurities when they fall to the bottom of the casing will remain there and the slab 25' prevents them from being carried to the opening 25.

The usual opening allowed at 25, is just sufficient to cause a drop by drop passage. A sight feed bushing 3!, with a glass covered opening 32, is provided so as to observe and check on the drop by drop passage.

A drain cools 33, is provided for cleaning pur poses.

- The solution now enters the pipe and passes check valve into the mining bushing 36, in the suction line it.

The chlorinated water now enters the pump it, where it is pumped. into pipe 31 then into the supply or pressure tank as which is provided with a discharge and valve til.

the arrangement desc =d thus far, when the tank full and vs is, is open, and the motor is s ated, the solenoid valve ill is automatically l tfid. and the system is in operation. The hypochlorite through the valve into the drip valve through "the sight feed 33, into mixing bushing 38 and d water is forced by the 0 supply tank 38.

re constant purity of aitoznatic devices for the resulting chi starting and stopping a the following:

In the line the motor current supply lines M, 45, there is inserted a pressure switch ii, of ordinary maize having the usual diapoints ilt-4i and the current hroiien, which system, I have devised automatically stops the motor i3 the pump I0, and by remote control desensitizes the solenoid which causes the valve 20 to close, which stops the supply of chlorine solution.

If however, the pressure in the tank 3! falls below a predetermined amount the contacts 43-44 will close and the current is on, causing the pump ill to operate and the solenoid valve 20, to open thereby supplying chlorine solution to the system.

In order to provide a means for stopping the operation of the system when the hypochlorite tank is becoming empty the following steps are taken. A board of insulating material 45, is provided with a metal arc 48. A float 41, which rises and descends as the solution is added or subtracted, is attached to an arm 48, which is pivoted at 49, and connected to the arm 50, and moves with it at all times. On the arm 50, there is a metal portion which is in contact with the metal are 45, and a wire is attached to said metal portion. A wire 52, is connected to the metal arm 46. The wires 5i-52 form part of the circuit l4-|5.

A warning signal as a bell 53, or a light can be employed to show that the system has stopped for lack of hypochlorite. In operation a switch 54, is hinged at 55, which is operated by the arm 50 when it is swung beyond the metal arc 48. The end 56, of the arm forces the switch 54, to close and make contact with the wire 51 and cause the current to flow from a source 58 to ring the warning bell 53 or cause any other alarm or signal.

In the operation of the system:

When the tank i6, is full of hypochlorite the current will pass through the are 48, through the wire in arm 50 then to the pump motor l3 it the pressure switch 4| is closed and by remote control to the solenoid valve 20.

If, however, the tank I, is empty the float will fall and the arm 50, will swing over beyond the metal arc 44, which will automatically break the current supply which will stop the system. At the same time the handle on the arm 50 will (:lose the switch 54 which will causethe alarm at It will be obvious that the invention is not limited to the specific form described and illustrated in the drawing but is capable of a variety of mechanical embodiments. Various changes, which will now appear to those skilled in the art, may be made in the form, details of construction, and arrangements of parts without departing from the spirit of the invention. Reference is therefore to be had to the appended claim for a definition of the limits of the invention.

What I claim is: In a chlorinating system, a chlorine solutio tank, a source of raw water supply, a mixing chamber, an electric control valve controlling the amount or solution entering said mixing chamber. a reservoir, an electric pump for drawing chlorinated water from the mixing chamber into the reservoir, a level finding means in said tank and arranged to operate a switch, a switch mechanism operated by the pressure in said reservoir, and electric lines running through said reservoir switch, though said tank level finding switch, through said electric pump and through said electric control valve and so arranged that should either switch become disengaged the current in the line stops and the electric control valve stops the supply oi! chlorine solution to the mixing chamber and the pump becomes inoperative.
