Theory of the astronomical transit instrument applied to the portable transit instrument Wuerdemann no. 26: a compilation from various authorities, with original observations by Harry Edward Burton, 1903, Page 2

Purpose of the transit instrument
The transit instrument is one of the most important of astronomical instruments.It is used principally for observing the transit of a star across the meridian of a place.
The instrument is used in connection with a time-keeper and the chief object of the observations is to determine the error of the timekeeper and get the correct local time.
Description of the portable
Transit instrument
The instrument consists of a small astronomical telescope mounted perpendicular to a light hollow axis. The telescope may  be elevated to any angle by turning it on its axis. and the axis is placed east and west so that the telescope will swing in the meridian plane.
The cylindrical extremities  of the axis are the pivots.They are made of cast steel and are as nearly equal in size as is possible.
