Description
f MTED STATES PATEN WILLIAM B. WHITING, OFVWAUKESHA COUNTY, WISCONSIN.
IMPRQVEMENT IN CONSTRUCTION OF HULLS OFAVESSELS.
Speciticatiou forming part of Letters Patent No. 187,74 2. dated February 27, 1877; application tiled November 29, 1875.
To'all whom t may conce-rn Be it known that I, WM. B. WRITING, of Waukesha county, Wisconsin, have invented certain Improvements in the Hulls otVessels, of which the following is aspecication:
AThe improvement in the shape of the hull of vessels for which I solicit a patent is a series of curved surfaces, forming the bottom of the vessel, extending from the bow to the stern.
Experiments have been made in Europe with what are termed serrated bottoms, consisting ot' a series of inclined planes, the first terminated' at its lower extremity by an upright wall, from the top of which another in clined plane extends, terminated in like manner by another inclined plane, and so on, until the stern is reached. The purpose of these inclined planes is to increase the buoyancy of the vessel, enabling it -to glide over the surface ot' the water, rather than force its Way through it, (as boys make dat stones to skip on the water by their shape, combined with velocity of motion,) with this peculiarity, that the draft is decreased as the speed is increased. These experiments have developed the astonishing speed of sixty-two knots, and it is believed that a similar result will be obtained by theV more perfect shape of' a series ,of curves, which I propose to combine with theshape of bottom now in use.
My design is more clearly shown by the annexed drawing, which is herewith iliade part of this specification.
The continuous line shows the actual shape in the proposed improvement, and the dotted line the shape now in use, which shape I propose to com binewith the curved surfaces described. vThe exact proportions are the radius ofthe curves to be twolthirds ot' their distance apart from eachother, from one center to another, that distance being equal to the depth of the vessel, exclusive otl the keel, which should extend a short distance below.
What I claim as original is The series ot' curved surfaces constituting the bottom of the boat.
