Slide-rules.-Problems relating to the loading and trimming of a ship are solved by means of a slide-rule of which the body 9 carries two slides 11, 12 and a hinged cover 10. On the body adjacent to the slide 11 is a scale 1 graduated in terms of tons per inch immersion and the slide bears a scale 2 of extreme breadths. The other edge of the slide is provided with an arrow 3 to indicate against a scale 4, on the slide 12, graduated in half-changes of trim. The other edge of the slide 12 and the adjoining edge of the body are engraved with scales 5, 6 representing loads and distances from the tipping centre respectively. On the cover 10 is a chart scale 7 formed by horizontal lines at distances representing tons per inch immersion and crossed by oblique lines subdividing them proportionately on both sides of a vertical zero line and marked in terms of changes in draft. In a recess in the body is carried a loose scale 8, graduated from a centre line in terms of weights. Given the tons per inch immersion and the breadth of the ship the slide 11 may be set accordingly and the change of trim read against the arrow 3. The scale 8 may then be placed along the horizontal line on scale 7 corresponding with the tons per inch immersion and with the zero on the oblique line denoted by the reading just obtained. Against the weight on scale 8 will then be read by means of one of the oblique lines the number of inches to be added to or subtracted from the draft, fore and aft. With any given setting of the scales a reading of load on scale 5 may be found against the corresponding distance on scale 6 effecting the given change of trim.
