IMPROVEMENT IN BOATS.
.. Specication forming part 0f Letters Patent No. 128,717, dated July 9, 1872.
SPECIFICATION.
LISAMUEL ELWELL, Jr., of Gloucester, in the county of Essex and State of Massachusetts, have invented certain Improvements in Boats, of which the following is a specification.
Figure l in the drawing is a top view with the cover removed, and Fig. 2 is a central ransverse vertical section of my improved oat.
This invention consists in a boat having longitudinal air-chambers, separated by a central partition, and having also air-pipes extending lengthwise of said chambers and tubes extending from the chambers through the sides of the boat, for the admission and outilow of water, all as hereinafter specified.
A A in the drawing represent the hull of a boat, in the center of which is arranged atank or reservoir, divided in the center by a vertical partition, b, into two compartments or chambers, G C', each of which is formed, near the top next the sides of the boat A A, with longitudinal air-tight tubes d d. The tank or reservoir is provided with a water-tight cover, e e. *Through the sides of the boat A A near the top, connecting with the compartments C C', are one or moreas may be required-tubes or pipes, fj". Water being introduced through the pipes f f', or by any oth` er suitable means, iills the compartments C C', so that the boat is evenly ballasted at all times. By means of the airtight tubes d d the boat is rendered safe from any accident liable to be caused by the overweight or shifting of the ordinary ballast in use.
Having thus fully described my improvements, what I claim as my invention, and desire to have secured to Ine by Letters Patent, 1si The combination, in a boat, of the air-chambers C C', pipes f f', and tubes d d', substantially as specified.
In testimony whereof I have signed my name to this specification in the presence of two subscribingwitnesses.'
