Not illustrated. 1912 Excerpt: ...the pen to the desired vertical line. Finally, the contact pressure of the pen on the record sheet is no greater than essential, and results from a small residual gravitational tendency of the carrier to rotate the pen point against the record sheet with a very gentle pressure. The siphon tubes are about 1% inches in diameter and the float is only slightly smaller. This gives a moving force capable of overcoming the unavoidable friction in a highly satisfactory manner, and the absence of any complicated mechanisms renders false and interrupted records almost an impossibility. 83. Time checks on record sheet.--As thus far described the barograph is complete, and with the aid of the driving clock and drum, which require no further description, gives highly accurate and continuous records. The detailed analysis of barometric records generally requires hourly readings. When record sheets are employed with ruled scales for pressure and time, there is always a difficulty in setting the record so that the ruled hour lines on the sheet indicate the true time. A similar difficulty arises in setting the pen to the correct point on the pressure scale. This, however, is of slight consequence if sheets are properly printed and cut with uniform margins and carefully placed on the cylinder. To secure easily an equally satisfactory result with the time record, the driving clock is provided with a dial and hands in the usual fashion. These moving continuously day after day enable the clock to be regulated to keep correct time, a result very hard to secure when the rating is done on record sheets that are frequently changed. More especially, however, the barograph is equipped with a special timemarking device which automatically operates once each hour at the instant the min...
