Hi Improvement in making Anchors. 



of science, we may expect also good service to the cause of 

 natural history, astronomy, and the arts: from the known 

 character of the gentlemen who patronize and manage the 

 undertaking, we have a right to look forward to satisfactory 

 results of this kind. 



We understand that a work consisting chiefly of selections 

 from the writings of Humboldt is in the press, which will con- 

 tain the most interesting information upon Mexico and its 

 mines: it will be edited and revised by Mr. Taylor, who has 

 engaged to add some explanatory notes to render it useful to 

 those who may be desirous of inquiring particularly into the 

 subject. 



IMPROVEMENT ON THE PRINCIPLE OF MAKING ANCHORS, BY 

 MR. G. HAWKES (THE PATENTEE). 



To prevent the difficulty and danger attending welding the 

 shank and the flukes of the anchor, and the hazard of burning 

 them a little distance from the part so welded, and where an- 

 chors most frequently break, it is proposed to make half the 

 shank and all the fluke in one piece ; and if the bars of iron 

 should not be manufactured in lengths sufficient for large an- 

 chors, those bars can be welded, and the welds separated from 

 each other in making up the bars in sufficient numbers to make 

 the fluke and half the shank. This being done, leaving iron suf- 

 ficiently large to make the crown, it is turned with the greatest 

 possible ease to the form of half the anchor. This process does 

 not require the heat approaching to burning, and will give the 

 anchor such a trial as in all probability it will never receive after; 

 and the difficulty in making those pieces is no more than making 

 iron knees, only that the iron must be faggoted, which will 

 ensure its strength, and will allow of an eye being opened in 

 each half of the shank to admit the wood-stock passing through 

 the anchor. Two pieces being made this way, they are brought 

 together and reconciled to the size, and to suit each other ; 

 leaving iron out at the crown to admit the opposite ring of the 

 palm, to clinch over each other, and bolt on to the fluke : thus 

 the palm gives collateral support to each half of the anchor ; 

 and a sufficient number of hoops are welded on the shank of 

 the anchor, and driven down each way till it is sufficiently 

 strong : this allows the stock to be made much smaller ; and 

 as the cutting one-third out to let it over the anchor is saved, 

 it will be much stronger, and will only require a thin plate of 

 iron with a shoulder screwed on each half of the stock in 

 wake of the anchor (which will prevent the anchor cutting the 

 wood) ; the shoulder is placed contrariwise on the half stocks ; 

 when hooped with one hoop and a toggle through at each end,
