UNITED STATES PATENT OFFICE.
ADAM WINGARD, OF SAN FRANCISCO, CALIFORNIA.
IMPROVEMENT IN CONSTRUCTION OF VESSELS.
Specification forming part of Letters Patent No. 119,488, dated October 3, 1871..
To all whom it may concern:
- Be it known that I, ADAM WINGARD, of the city and county of San Francisco, State of California, have invented Improvements in the Construction of Vessels; andl do hereby declare the following` description and accompanying drawing are sufficient to enable any person skilled in the art or science to which it most nearly appertains to make and use my said invention or improvements without further invention or experiment.
My invention relates to improvements in the construction of the hulls or bodies of sea-going and river vessels, in order to admit of their attaining a high rate of speed, and at the same time preserve all the harmony of outline of our finest ships with equal carrying capacity.
In order to attain the advantage of a high rate of speed I employ the fiat-bottom or scow-shaped hull, and by a peculiar construction of the bow and stern I am able to obviate the faults and secure the advantages of this construction of vessels.
In order to explain my invention, reference is had to the accompanying drawing forming a part of this specification, in whichf Figure lis a longitudinal section. Fig. 2 is a bottom View. Fig'. 3 is an end view.
A represents the hull or body of any vessel. The bottom B of this hull is made flat, and the ends are rounded from the bottom toward both the prow and stern, at each end, in the usual manner, thus giving a horizontal wedge as a resisting surface to the progress of the vessel, and a following incline to clear the water from underneath the iiat hull at the rear. At each end of this hull I provide two pointed ends, c d e f, one being placed at each quarter ofthe vessel. These pointed ends are constructed upon sharp lines, as shown, and gradually widen as they advance toward the center ofthe hull until they merge into the flat bottom on the same plane. The lines v upon which these bows or cut-waters unite with the horizontal wedge of the bottom are rounding, thus forming an incline channel with circular bottom between them, which contracts and grows more shallow as it approaches toward the middle of the bottom. The incline at the fore end of the ship is longer and more gradual than at the stern, and the cut-waters are, consequently, of greater length. The sides of the hull are built upon regular lines, s'o as to give the least resistance pos sible to the progress of the ship.
rFhe advantages in thus constructing the hulls of vessels may be summed up as follows: The double bows serve to cleave the water, and instead of throwing it to the outside to heap itself up against the side ofthe vessel, and by burying' it to an unusual depth retard its progress, turn it on easy lines similar to the action of the moldboard of a plow, and direct it through the channel between the pointed ends under the bottom of the boat, where they serve to buoy it up and thus materially aid the forward motion of the vessel. IIhe same construction of the rear end enables the water thus directed beneath the vesel to clear itself freely through the channel be sween the bows cf. Besides this, I am able to greatly increase the width of beam of the vessel and retain its sharp lines, so that its progress in the water will not be materially diminished, as would be the case with a vessel of the ordinary construction.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-
The flat bottom B, in combination with the double-pointed ends c d c f and concavities D and E, as described.
In witness whereof I have hereunto set my hand and seal.
