1873 - Old Forge Coal Mines

INSPECTORS OP MINES. 73
Ike head of one of the screws conceals the slot in the bar, which admits a
slight vertical movement to the screw when loose, and with it to that end
of the tube. Therefore, in order to adjust the bubble this screw is first
loosened a little and then moved up or down a trifle, as may be required,
and then tightened.
A strait edged bar is laid on the incliue plane upon which is laid the
Clinometer, and the bubble limb of the instrument is moved to a horizontal
position until the bubble rests precisely at the centre of the tube, the upper
edge of the tube limb will bisect the degree on the metalic quadrant corresponding
to the degree of dip or slope of the incline plane.
These instruments are found very convenient, and may be, carried in the
pocket without any inconvenience. They accurately measui*e any angle of
dip corresponding to the degrees on the quadrant, and are very useful for
miue managers, being convenient, portable and accurate.
Numerous illustrations of the utter recklessness with which men will expose
themselves to terrible dangers, although acknowledged imminent, are
familiar, invisible and temporary doubtful, both in connection with land and
maratime steam boilers. In Great Britain the "Mine Regulation Act,"
under the head of " General Rules," states "
: Every steam boiler shall be
provided with a proper steam gauge to show, respectively, the pressure of
steam and the height of water in the boiler, and also with a proper safety
valve."
