A FLOATING BATTERY, 
ON A NEW CONSTEUCTIONj 
JBy the late ABRAHAM BLOODGOOD, - 
rr^ 
A HE model of this battery was exhibited to the 
society, with a verbal description only. The an¬ 
nexed plate shews an exact profile view of its body, 
the shape of which, as seen from above, is circular- 
It is to be connected at the centre of its bottom 
with a strong keel, in such a manner that while the 
keel is held by cables and anchors in one position, 
the battery is made to turn round on its centre* 
This motion may be given to it, either by the tide 
acting on float-boards, attached to the body of the 
battery; by sails raised on its exterior parts, or by 
manual application. In this;; last way it may be ef¬ 
fected by men in the hold, drawing on a lever fast¬ 
ened to a post fixed to the keel, and rising through 
a well-hole in the centre of the battery. The 
strength of horses might perhaps be applied to the 
same purpose. The cables, by which the keel is 
held, are to be entirely under water, and thhs se« 
cure from an enemy’s shot. 
The advantages of such a battery would be t 
1st. Its rotary motion would bring all its can¬ 
non to bear successively, as fast as they could be 
loaded, on objects in any direction.
