Be it known that I, HARVEY V E'IIGLEY a citizen of the United States, owl resident of Detroi'i; VJe iie county Stale Michigan, have iiivei tecl certain new and useful Improvements in Gas-Measuring Appomtus, of which the following is a specification.

The present invention relates to gas measuring apparatus and more particuloi ly to an apparatus for accurately measuring out volzones, 2 a The-apparatus has been clevised particularly for measuring volumes of sulfur clioxid to be tested for purity and content, although, as Willbe appei'en'l; it is not limited to this use. 4

The prinoipel features of lime invention consist in the provision of means for cleliv Qiiligf volume of Whichlieve been measvicli eme occuracy; in she pro; vision of means closely adjacent the meesui in}; means for determining the temperature and. pressure of'the gas; in the provision of an oppomius-which is free from pockets which might interfere with accuracy of the measuring; in the provision of an; apparatus of the type'mentionell constructed and ar rengecl to deliver all the gas'measur eci and in the provision of an apparatus Wliich is easily manipulated. StilBI features and objects will be apparent from ilie description iaken in connection with the olrewings in Whici 2' e l e. frontelevetioii of on opporaitvs constructed in accosfieoce with the present invention; v Y

Fig. 2 is a versicsl transve se section taken substantially on the line of 1, the "tubular ports attached to the iioiis thereof being omitted; anci F 3' is sectioniil view illustrating a fluiiil taken substantially on the lme 8-v- 3of 1 Y Referring to the drawings it will be seen that the opyamtus comprises o verticel rec.- iaogulor backing board 10 supported by the fool pieces 11 encl pivotelly carrying, as by means of theoolt l2, efrons iecteiigula board 13 which is of smaller than the backing board 10. As shown, 'the board 13 is spaced frointhe board 10' end isso held by 'm'eans of the spalcmg sleeve 14 eround the bolt 122ml the blocks '15 securerl'to the. A

back board 10 adjacent three of cneco rners of the front board. At the other c0r1ier,' the upper. right hand corner of Fig. 1, the from v board has e pin 16 which is'odaplced to o l-{1Q gage in any one ofelie three recesses-1'? formed in the buck board As Shown the front board carries a spacing sleeve 18 which slides on the wear plate 19 carried by "the 6 back board, and e soringQO within the sleeve acts against av collar 21 securedio the pin 1,6 to force the latter? into oneof the recesses. It will be seen that the recesses 17 are s j ranged so that when the pin 16 is in the central one the from; board is horizontal and? when in either one of the end-recesses '17 the i;- saidboard is tilted to the left or the'riglit accordio to which hole the pin engages. The parts of the apparatus-Which are used for measuring the gas are secured in any suitable manner so the front side of the board 13.' As shown they'compriseh sub- 1 stantielly cyliiiclricel gas holder-o1 messes" f ing vessel 22 having conice-

l ends

23 and 24, 75 the latter being retiuced down to form the tubular extension 25 provideol with a stop cook 26, this portion 25 being connected by mcans of a rubber tube 2? to a vessel 28 containing a liquid such as mercury. Isis necessorylo raiseend lower thevessel 28 and for chis' purpose any suitable supporting means may-be provided. As shown, theses sel Tests ine ring29 slidebly supported-on a vertical bar 30 secured to the back board 10. A thumb screw 31 is provided to lock the King 29 to the bar 30 in any (lesi're vertical adjustment. l

The upper conical'end 28 o'f'thegas holder 22 is reduced down to form tiie-tube32 having a stopcock 32 and constitutes the stem. of a T At the left of the stem the horizontal portion of the "i" is provided with a stop cock 33 and immediately at the-Tight with a stop cock 34. To theleft of the stop cool: 33 the tube extends horizontally to a ground glass coupling connectionfio which joins the tube 36 to a tube 37 in the form of on iii j verteo U this being provided-for the purpose of preventing mercuryfrom passing out through the encl of the tube37,-in case the mercury is allowed-to flow .pasi', the stop cock 'At the right of the stopjcoek 34 is'a T 38 connecteclby a ground glass coupling ice 11st at tho 1; em ll of jiahe lower and atmosphere.
