T 's invention relates to an improvement iu hollow bolts for ship-building-purposes, in which a large proportion of metal may be utilized, while it will be fully as strong as those heretofore employedt It consists in vproviding one end of the hollow bolt with a series of concentric grooves, so arranged that the bolt may be easily driven into the wood, but cannot be withdrawn.
A, in the drawings, represents a bolt made of tubur lar iron, or other suitable material, of suitable length and diameter. Ooncentric grooves, a a, are formed around it, near one end, as shown in g. 1, to make it hold in the wood. When the bolt is driven into the wood, it will enter very easy, but cannot again be withdrawn, as the sharp edges ret-ain it, harpoon-fashion,
end with a series of concentric grooves, a, which permit the boltto be easily driven into the wood, but prevent it from being withdrawn, as herein shown and described.
