“For an improvement in Canal Boats; Thomas W. Bakewell, Cincinnati, Ohio, August 25.
The object proposed to be accomplished in the improved canal boat, is, to fix an awning above the roof, or top, of the cabin, which awning may be lowered to admit of passing under a bridge. A patent for a contrivance for the same purpose was granted to Jacob Bromwell, of Cincinnati, on the 23d of June last, and is noticed at pg. 190. The support of the roof, or awning, as described by the present patentee, is to be constructed of light pieces of timber, so framed and jointed, that they may double down upon the permanent roof, upon the principle which regulates the approach of the two sides of a parallel ruler, as will be seen by the claim, which is the application to canal boats of the forementioned principle, which principle is that on which the parallel ruler is made, and by which a rectangled parallelogram may become a rhomboid, and vice versa, the sides remaining unchanged.
It is proposed, as in Bromwell's patent, to render the awning self-acting, by a projecting piece, properly fixed, to strike against the bridge, and press the framing down; it may also be made to rise spontaneously by a weight acting over a pulley, or by other means.”
