1875 Replies to[4094] - Testing Sheet Lead.—Some years since I invented a gauge for measuring the thickness and weight of metal and other plates, the principle of which is the progressive movement of an accurately cut screw. To this is affixed a circular or micrometer head, vide the catalogue of the Great Exhibition in 1851, Class 10, No. 298. In this the outer circle on the dial is divided, so that each minor division represents 1oz. per foot super of sheet iron, the pounds and quarters being marked off up to 20 lb. to the foot, which is exactly half an inch in thickness. The next circle is so divided that each minor division represents the to 1000th part of an inch ; this line is suggested for adoption as a practical application of a decimal nomenclature for an imperial gauge, in lieu of the arbitrary and conflicting measures now in use, few of which have any definite value with respect either to thickness or weight. This observation applies particularly to the Birmingham wire-gauge. On the inner circle I give a line of numbers for this gauge ; they are the mean results of many trials with gauges issued by the various manufacturers, and of reference to the works of those who have written on the subject, all of whom, however, differ as to the thickness they assign to almost every number — there is not any standard. I have a very small gauge, made expressly for architects and surveyors, with simply two lines of numbers. One gives, at sight, the exact weight per foot super of lead up to 8lb., and the other line of glass up to 32oz. to the foot. From either gauge may also be ascertained the weight per foot super of all other substances by the use of my sliding scale of equivalents.
P.S.— The above is a revision of my reply in March, 1872, to question 2498, which was headed " Gauging Sheet Lead."—Edwd. L. HAYWARD, 187 and 189, Union-street, Borough, S.E.[2]. See 1851 Great Exhibition: Official Catalogue: Class X.: Hayward Brothers
