On the righthand side of the machine 

 there is a small single-cylinder steam-engine 

 with flywheel c and shaft h lïtted with the 

 sliding pinion e, which drives the winding 

 drum C by means of the toothwheel g. 



At the back of the machine there 

 is a light revolvingf Davit / carrvingf the 

 guidepulley n. 



The Davit can be adjusted with the 

 handle P . 



The lower part of the guidepulley 

 L runs in a small sheet-iron tank, not 

 shown in the engraving. 



The necessary oiling arrangements IJ 

 are fitted where required. 



Run of the sounding-line. 



This line consist of steelwire 

 0.9 mm. diameter and is wound on 

 the wire drum. From here it runs 

 over the top-guide-pulley u to the 

 winding-drum over which it is passed 

 five turns, from there over 

 the guide-pulley L to the 

 counter pulley U and upper 

 doublé pulley Z, from there 

 to Z\ upwards again to the 

 doublé pulley Z and from 

 there to a Davit and over- 

 board. 



The whole apparatus 

 was placed on the extreme 

 port side of the bridge. 

 The outer Davit was iïxecl 

 to the fixed shield-plate of 

 the 3.7 cm. gun. 



The soundingf 

 lead is attached to 

 the wire by a light 

 ground line of about

six metres long-. At the 

 upper end of this ground- 

 line there is a small lead 

 weight of two to tlWee 

 kilooframs. This ground- 

 ine and auxilian* weight 

 is to prevent kinks taking 

 place in the wire, which 

 is very apt to occur and 

 to cause the breakage 

 of the line. 



Experience proved 

 that a length of six metres

 well.
