An improvement in Capstans has been made by P. C. Bryant, ol Camden, Me., who has taken measures to secure a patent. The capstan may be used as a common capstan, and changed at once so that a far greater leverage can be obtained by interior gearing, but which, as a consequence, requires longer time in operation. This capstan, we believe, will be exceedingly useful, especially for vessels which have sxall crews, who sometimes have very heavy weights to elevate.— The capstaa occupies no more room, and has the very same appearance as the ones in pre- sent use; the machine which is added to effect the object stated, consists simply of some bevel pinions and one bevel plate wheel.
