INVENTOR Arthur J. 'zzrm'myzwm ARTHUR B. CUNNINGHAM, OF TOLEDO, OHIO.
GAS ANALYZING AND RECORDING APPARATUS.
Specification of Letters Patent.
Application filed April 8, 1919. Serial No. 288,446.
To all whom it may concern Be it known that l, ARTHUR B. CUNNING- HAM, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Gas Analyzing and Recording Apparatus, of which the followin is a specification.
This invention relates to mechanism for determining the percentage of a gaseous constitutent in a gas, such as carbon dioxid in products of combustion, and automatieally recording the same and any variation thereof on a time operated chart, so that by comparing the readings, the volume or amount of the particular constitutent in the gas at dili'erent times may be ascertained.
The drawings illustrate a preferred embodiment of the invention. However, it is to be understood that in adapting thesame to meet different conditions, various changes in the form, proportion, and minor details of construction may be resorted to without departing from the nature of the invention as claimed hereinafter.
Referring to the drawings, which illustrate the preferred embodiment of the invention,
Figure 1 is a diagrammatic view.
Fig. 2 isa top view of the tank and parts contained therein.
Fig. 3 is a sectional detail on the line 3--3 of Fig. 2, a portion of the fluid countcr- 1 balance of the recording mechanism being broken away.
Fig. 4 is a horizontal section of the variable gas receiver or measuring chamber on the line 4.-4. of Fig. 1.
Corresponding and like parts are re ferrcd to in the following description and indicated in the several views of the drawingsby like reference characters.
The pipe leading from the source of gas supplv such as a furnace is indicated by the numeral 1. The water supplying pipe is designated by the numeral 2 and may conneet with a water main or other source of water supply. The waste pipe for carrying oflthe spent water indicated at i-h thc tank for containingeerL- in parts is indicated at 4 and comprises a. vertical portion of some considerable depth and a lateral portion which is relatively shallow, indicated most clearly in Fig. 1. An opening 7 is provided in the lower portion of the tank and a pipe 12 leads therefrom and connects with the gas supp y pipe 1 some distance above the tank 4.. A. branch pipe 1 connects the pipe 1 with the pipe 52 at a point above the tank 4-. A nozzle 5 is located in the pipe 2 about in line with the branch 1". A valve 11 is located in the pipe 1 at a point between the connections of the ipes 12 and 1" therewith. The water is supplied to the tank from the pipe 2 through a pipe 6 and as the level of water rises in tank 4 it asses through 0 mm ing 7 at bottom of tanli into tubes lea ing out. The surface of water is never below 7 and this is always sealed from air. Jet 5 produces a partial vacuum at 9 and draws in a quantity of gas at 1. When the water level in 4 is low, float. 10 closes valve 11 causing the gas to pass by way of pipe .12 to point 8, thence through tube 8 into and filling measuring chamber 13. The gas passes out at bottom of measuring chamber through pipe 13, branch 1* into ipe 1 and out. through branch 1" into the pipe 6. 'As the water rises in tank 4 it of course rises in the tube 12 leading out of 7 and when it reaches point 8 it traps a certain volume of Patented Au". 5, 1919.
gas in measuringchamber 13. 'The water i also elevates float 10 opening valve llallowing the gas to pass directly through and out by the jet 5. As the water continues to rise it forces the gas out of measuring chamber 13 through the tubing 13" at the top leading to the bottom of absorption tank 14. This tankis filled to about point 15 with a reagcnt to absorb the gas to be determined. As the bubbles rise through the solution they strike baille 16 causing them to travel more slowly and with ,a rolling motion. It is also necessary for it to travel a much greater distance through the solution giving ample time for the solution to absorb all the gas subject to its action. As the gas enters 14 from tube 13" it forces outa quantity of gas equal to that not absorbeti by the reagent. This gas escapes through pipe 14" and enters measuring chamber 17 which is an inverted cup working on stem 18 in guide 19. The cup 17 works in receptacle 2() which is filled with water to drainage point 21, the water strikes arm 24, working on point 25. mov

These tubes are united at the top and connected with the waste means of a flexible gum tubin 27*. tube 22 is in no way connector with float 26 or any of the siphon apparatus. See Fig. 2 which shows more clearly the tank 4 and contained parts looking down from the Note are held The float 26' and tubes 27 and 27" 2t) and in position by stem 28 and guides whichgives stem 28 room to swing in circle with the gum connection tubing 27 as the float 26'rise's. \Vhen the float 26 which is open at the top, strikes uide '29 it stops and as the water rises to the top of the float and flows therein the float 26 fills and quickly sinks carrying with. it the siphon tubes 27 and :27".

As the gas passes out, 17 lowers to its original position'ready for the next charge of gas.
When the water in tank 4 reaches the lower end of siphon tube 27 it admits air and immediately the flow of water stops.
It has now completed the cycle and is ready for a new charge of gas.
No claim is made for recordin chart, clockwork for operating eiart, or
means,
chemical compound for use in H to absorb v gas. I may use reagents in be prepared or special recontinuous analysis and recor ing ofahy eneral use, or
be used for single gas in a compound' providing the;
proper reagent is used to absorb the gas in 14. It is especially designed for recording the percentage of carbon dioxid in ases of combustion. The two tubes 27 an 27, and the risingk and falling feature are the principal wor ing parts. All previous siphons workpicely when they have exactly the proper amount of water supplied. If not enough they will drain over and the siphon will not flow. If too much is su plied the siphon will not sto as it shouiil but will continue to carry 0 the water as supplied. \Vith this arrangement no water can drain off, no matter how small the supply, until the siphon tubes connected to 26' sink. Then the siphon starts flowing at full velocity. When the water level reaches the lower end of tube 27 the tube admits, air and the flow of water stops immediately. By
this method the system-1s enabled to operate regardless of the flow of water. It is of course evident thatv itthe flow of water isslow the cycles of operation will not be coinpleted as quickl as when the supply is more abundant. but t to principal point is that the cycles will be complete.
The arrangement of valve 11 gives a cqn-. tinuous supply of gas fresh from the source. It is not necessary that valve 11 should close tightly as it is only a deflector when the gas should be diverted through measuring chamber 13. Point 8 is slightly point 21.
below the bottom of measuring chamber 13 The tubes leading upward from point: 8 to chamber 13, and downward from 13, are very small the volume of gas measured is always uniform, therefore 17 will always he raised to a corresponding height less the volume of gas ahsorhcd in 14-. The water supply in almost every instance is cold. I
have placed a coil 1% ol' the water supply tube in the water seal in '30 to keep it cool and condense anymoisture that might. be carried from it. Some of the moisture will he condensed in the tube leading from 14 through the cold i'atcr of :20 and run back in the solution of '20. Any moisture that escapes through thistuhc will he condensed on the surface of the cold water of 20 keeping the water at constant level of drainage tv will he necessary to only occasionally add Water to H. It is not necessary that; either 14 or 30 maintain a constant let e1, hat is better that both he kept to the proper levcl. It is ohserved that the gas in the final measuring chamber 1? is the same temperature that it was in the first measuring chamlgnrr 13, this being essential to avoid any variation in volume of gas. llc makes no claim to cooling the gas. I use the coil 2 for a two-fold purpose, to condense any moisture in the gas thereby uaintaining a constant; level in :20, and to maintain a constant. temperature for linat nieasiu'cincnt. The hatlle it, in 14 incrciu-ieshv three times the distance the gas must travel through the reagent. It also gives, the huhhles a rolling mot-ion exposing them more to the actio of the reagent. This permits the use. with good results, of reagents until completely exhausted.
The foregoing description and the drawings have reference to what may he considered the preferred. or improved form of my invention. I may make such .changes in construction and arrangement and combination of parts, i'i'iaterials; dimensions. ct cctera, as may prove expedient and tall within the scope of the appended claims.
