1^^ APPARATUS FOR RAISING BODIES UNDER WATER.

the ropes would entangle. But if a rope is fastened either 

 to the middle of the floating-bar, or to that rope which ope- 

 rates as an anchor to it, by means of this the whole macliine 

 may be drawn back, and the same sweep repeated as often 

 as required. 



Should the floating-bar, for the purpose of disengaging 

 any particular drag, be thought unnecessary, but that it is 

 desirable to know what direction the one sunk is taking, and 

 that the drawing backwards and forwards is an object, the 

 floating bar, provided the lioles at the ends of it are made 

 sufficiently large, will do this by changing its direction from 

 being a following bar into that of a leading one by this 

 means. Detach it from the drags by untying the ropes that 

 connect it with the bottom swivels. Pull them out of the 

 floating-bar, and then pass the two ends of the principal or 

 . drawing rope through the holes next the end of it, and let it 

 slip down to the leading bar; its own buoyancy will bring it 

 to the surface of the water, and the operation of a man's 

 pulling the drawing rope, will, by compression, keep it 

 there. 



The costof this drag and appendages is three guineas. 

 Fig. 2, represents the drag in the state in wliich it should 

 be preserved ready for use, or the manner in which it should 

 be carried from place to place, to prevent any part from 

 entangling. G G is a pole over which that part of the ap- 

 paratus marked A and B is laid, and on which the cords 

 D D folded up are hung, the drags C C C C remain sus- 

 pended on the nearer side <rf the pole, and the floating bar

 low it.

 the security of persons going to the a^isistance of a drowning 

 person, or diving for them.
