IMPROVEMENT IK ANCHORS* 



moo method, in order to prevent the anchor stock frdtrt 



slipping off the shank, a square projection b b, fig-. 8, is 



ferged upon the thank; this is improved bj Captain Ball, 



as shown in fig. 6, where this projection dd is extended on 



each side of the shank, far enough to receive two bolts 



through each of these extensions, which bolts hold firmly 



together the two pieces of timber that form the stock, and 



secure the stock fast to the shank. Two iron hoops, fig. 7* 



ee, are driven on the stock between the bolts, and//// 



are other hoops, and gg gg are treenails to strengthen the 



whole.

used for this purpose. 



In the usual operation of heaving an anchor, it is drawn 

 tip by the cable until it appears above water : the cable will 

 not now raise it higher, it is therefore bowsed up by the cat 

 block a, fig. 4, from the cat head 6, the cable d being 

 slackened out as it rises. When it is got up as high as the 

 cat block will raise it, a strong hook, called the fish hook, 

 fastened to a rope e, which is suspended by a tackle from 

 the shrouds, is hooked to the anchor at the bottom of the 

 shunfe, and thus the arm* of the anchor are elevated above 

 the stock, until one of the flukes is brought up to the tim- 

 ber heads//, to which it is made fast by a rope and chain, 

 called the shank painter* In this operation the fish hook 

 sometimes slips and occasions mischief, to remedy which, 

 Captain Ball has applied two hooks instead of one, which 

 keep firmer hold. These hooks are shown upon an en- 

 larged scale atg-g- fig. 5, attached to the rope e ; each of 

 these hooks takes one of the arms of the anchor, close to 

 the shank, and holds it firmly, i i are two small lines made 

 fast to the hooks, to direct them so as to get proper hold of 

 the anchor.
