A new Centre-Board Wrench. - Mr. E.C. Hammond has invented a centre-board wrench which works with a "worm" instead of spur gearing, being as fast or faster in operation than the ordinary wrench and not complicated. It does away with all danger of lowering the centre-board, and appears to be an excellent contrivance. Vessels builders and others would do well to give it their attention. They will doubtless find it for their own interest to do so.

It was exhibited at the State Fair, and is thus spoken of by the Rochester Democrat of Thursday:

Hammond, Pennock Co., of Oswego, have on the Fair grounds a model of a centre-board wrench, which displays much ingenuity and we should judge was admirably adapted to answer the purpose of the invention. It does away with all danger while operating, being worked by a worm wheel in place of spur gearing.

They also have a pump, a combination of the bilge and centre pump, for use in vessels. It is arranged with a sliding valve and three pipes, one for each side and one for the centre of the vessel, so that whichever way the vessel careens the pump works equally well.
