As it is sometimes desirable to vary theposition of the atmospheric line on an in-dicator card, provision is made,for adjust-ing the piston rod by means of the swivelhead shown. The pawl and ratchet detent motion hasbeen replaced by the well-known ball formof friction clutch, not shown in detail whole instrument has received care-ful attention, from the body to the smallestpart, and the design denotes strength asa foundation for its other good makers are also prepared to furnishcomplete outfits from mdicators to blanksfor taking VIEW OF ST.\R of Utility. The pencil movement is of theThompson pattern, chosen for its strength,durability and light weight. The springs have the ball at lower end,which has proved so satisfactory in yearsof service. The drum spring, as will benoticed, is a plain helical coil—anotherdevice which has proven its worth in act-ual service. The interior cylinder or shellcarries the cap at the top, always insuringalignment between piston and rod. Thisin no wise interferes with removal of shell,should it become necessary. Around thisshell is a steam space which, being filledwith live steam, jackets the working cylin-der and secures uniform temperature andexpansion. A feature which will be appreciated bythose who have vivid but unpleasant mem-ories of burned fingers is the non-conduct-ing cover over the cap at top of enables it to be removed both rapidl
