APPARATUS FOR GHLORIN CONTROL.

Application filed April 11, 1921. Serial No. 460,522.

To all whom it may concern:

Be it known that I, JAMES W. VAN METER, a citizen of the United States of America, residing at 2977 Clay street, San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Apparatus for Chlorin Control, of which the following is a specification.

The present invention is an improved apparatus for chlorin control, and relates, to an apparatus for delivering a measured quantity of liquid chlorin or chlorin gas as, for instance, in water purification, or in the preparation of dyes, bleaches and laundry preparations.

The primary object of the invention is to provide a method and apparatus for handling chlorin with safety and in such a manner that the discharge or admission of the chlorin is visible and may be controlled to a very delicate degree.

Chlorin is a deadly gas, and, as it enters into the various trade uses more and more, it is essential that means he provided which will accurately and intelligently supply chlorin in a manner that can be carefully watched and will not be a menace to human life.

With the apparatus hereinafter described I am able to introduce chlorin, under pressure in measured quantities, into a volume of water or other liquid.

Again, it is sometimes desirable to apply chlorin in a moist state, and with my apparatus I can conduct chlorin gas through a volume of water to produce this result.

An essential feature of my device is the fact that the movement of chlorin is visible and the results may be gaged and regulated with the greatest accuracy.

In this specification and the annexed drawings, the invention is illustrated in the form considered to be the best, but it is to be understood that the invention is not limited to such form, because it may be embodied in other forms and it is also o be understood that in and by claims following the description it is desired to cover the invention in whatever form it may be embodied.

In the accompanying one sheet of drawings, Figure 1 is a side elevation of my chlorin apparatus.

Fig. 2 is a front elevation of the parts shown in Fig. 1, but on a smaller scale and showing a pipe line connection with a contalner of liquid chlorin.

Fig. 3 is a vertical cross-section taken on the line IIIIII of Fig. 1.

Fig. 4 is a section of Fig. 3 taken on the line IV-IV.

Referring to the drawing, Fig. 1, the numeral 1 indicates a base casting provided W1tl1 2tI1 upright standard portion 2, which terminates in a horizontally disposed ring 3.

The ring 3 is adapted to admit therethrough a reduced portion 4 of a dome shaped casting 6 (preferably formed of porcelaln). lVhen the reduced portion 4 of said casting dome casting is supported on an annular ledge 7 on the casting which rests on the top ring 3.

The depending flange or reduced portion 4 1s provided with two diametrically opposed lugs 8 and 9, Figs. 3 and 4, extendlng radially inward for purpose to be later described.

An internally threaded collar 11 is provided with an annular flange 12 which has two cut away portions adapted to clear the lugs 8 and 9, and when the collar is inserted and partially rotated to allow the lugs to support the weight of the collar.

Threaded with the collar 11 is a glass jar 13 open at the top. ed into the collar 11, the action of the screw threaded parts forces the annular open end of the jar 13 against a rubber gasket 14 to form a water tight joint. At this time the rubber forces the flange 12 into intimate engagement with the lugs 8 and 9. relieving the strain from the glass, and the parts are thus securely held against dismcmbcrment.

The casting 6 is hollow, a chamber 16 extending throughout the dome. A- tubular member 17 extends upwardly into the chamber 16 and is provided with orifices 18 near the top. The floor 19 of the chamber 16 is provided with two ports 21 and 22, Fig. 4, which connect the chamber 16 with the interior of the jar 13.

Communication is made with the tubular member 17 from the exterior of the dome, by a passage 23, Fig. 3, which is preferably tapered for a force fit engagement with a rubber hose 24.

A similar passage 26 connects the interior is inserted in the ring 3, the

lVhen this jar is thread of the jar 13 with the exterior of the dome 6. A rubber tube connection 27 is made with one end of this passage and a reduced neck portion 28 of a funnel shaped member 29 is fit snugly into the opposite end of said passage.

The funnel member 29 is open at the bottom end and provided with a very small bleeder port 31 in the side wall near the top. The funnel shaped member 29 is graduated as shown at 32 for purposes to be later described.

In Fig. 2, I show a U-shaped glass tube 35 provided with a sight bulb 33 formed thereon. One end of the tube 35 is connected with a service tube 34 leading from a chlorin cylinder or container 36 controlled by a valve 37.

Assuming that the parts so far described are assembled as shown-in Fig. 2, the chlorin cylinder 36 resting on the floor and the casting 1 on a shelf 38 supported by 'a bracket 39, and that it is desired to moisten a quantity of chlorin for laboratory use, water is introduced from a hose 24 through port 23, Fig. 3. As the water enters it sprays into chamber 16 and gravitates through ports 21 and 22, filling jar 13, and fills the chamber 16 until it reaches a level determined by that of an outlet pipe 40, Fig. 4, connected with passage 41.

The level of the water will be indicated in the sight bulb 33.

Now, if the valve 37 Fig. 2, be opened, chlorin under pressure will enter through port 26 and find its way to the interior of funnel 29. As the chlorin (under pressure) enters the funnel the water therein is dis placed, being forced downward, until the chlorin pressure balances that of the water. The chlorin will slowly escape through the orifice 31 in bubbles, rising through the surrounding water.

If the water supply pipe 24: be shut off, the level of water in chamber will lower and moist chlorin will be driven off through discharge pipe 40.

If dry chlorin is wanted and it is desirable to measure and watch the delivery, I use kerosene in place of water.

If it ,is desired to chlorinate continuously a running stream of water, I connect a service pipe to the passage 23 and a delivery pipe to the passage 41. This carries incoming water to spray from the orifices 18 and fill the jar 13 and chamber 16. 'Chlorin is admitted as before andI find in prac- -tice that I can deliver to a body of flowing water various predetermined amounts of chlorin, in a definite proportion of chlorin to water, regardless of any changing pressure or velocityof the water.

I find if water is sprayed into a chamber containing chlorin under pressure that it absorbs chlorin very quickly.

Having thus described my invention, What I claim as new and desire to secure by Letters Patent of the United States is .1. An' apparatus for chlorin control, comprising a chamber adapted to contain a liquid, a transparent vessel below said chamber and adapted to be fed with liquid therefrom, a receiving vessel within said transparent vessel, means for supplying chlorin to said inner vessel, said inner vessel having a bleeder port through which chlorin exudes in drops into said liquid.

2. An apparatus for chlorin control comprising a transparent vessel adapted to contain a' liquid, a receiving vessel within said Vessel also of transparent material and open at the bottom end, means for introducing chlorin under pressure to said inner vessel and thereby displace said liquid in said inner vessel, said inner vessel being provided with an aperture adapted toallow the chlorin" to escape through said liquid in quantity determined by the pressure of the said chlorin.

3. An apparatus for chlorin control com prising a transparent vessel adapted to con- .tain liquid, a receiving vessel within said vessel also of transparent material and open *at the bottom end, means for introducing chlorin under pressure to said inner vessel and thereby displace said liquid in said in with an aperture adapted to allow the chlorin to escape through said liquid in quantity determined by the pressure of said chlorin, and graduations on said inner vessel whereby the quantity of chlorin so discharged may be gaged by the relative levels of liquid in said vessels.

4. In a chlorination device, means for setting up a circulation. ina body of liquid by discharging chlorin under pressure 'in bubbles below the surface of said liquid to cause the liquid to ascend on one side and to descend on the other side.

5. A cholrin control apparatus comprising aclosed chamber divided into upper and lower compartments separated by a floor or partition provided with apertures to perinit circulation of water between said compartments, means for spraying water within said upper" compartment, a tube within said lower 'compartment open at the.

bottom end and provided with an aperture I JAMES W. VAN METER.
