OF
AN ECCENTRIC BAR PRESS,
For clearing wetted goods of Water.
This press (see [Plate 21], [fig. 2]) is indefinitely powerful. It was invented for the use of my late beloved brother, then contractor with government for cleansing the sea bedding. It is composed of a centre piece A, strongly fixed to a post in the ground, the bars A B A C being suspended above it, so as to remain horizontally moveable, while describing 1⁄4 of a revolution round the general centre A. The blankets (or other goods) are put into the space s, (on a net nailed under the bars) while in the position A B; and the whole is then thrown with force towards B C; the length A C being so calculated as to cease pressing at the desired moment: for such is the power of this Machine, even without this projectile force, that were the stress not moderated, nothing could remain whole under its operation. It is clear however, that, when this operation begins at s, the relative motion of the jaws s and B is assignable, and even visible, as shewn by the dotted circles; but as the whole approaches toward B C that relative motion becomes insensible, the circles parallel, and consequently the power infinite: which is all I shall say on the theory of this Machine.
