J. and W. PEARSON, Solway Foundry, Maryport, the proprietors of the above-named Patent-right, beg to direct the attention of Shipbuilders and Owners to this Invention; and have to observe that it has received the sanction of Lloyd’s to stand 12 A1 in vessels built to the usual rules, and that all vessels hitherto on this plan (the names of which, with any other particulars that may required, will be furnished on application,) have given the greatest satisfaction to the owners, and all parties interested in their stability and economy, as well as by the peculiar advantages this plan possesses over any other mode of fastening, allowing a fresh circulation of air through the vessel. To Proprietors and Builders of large Steam Ships, where the tendency to work, as it is technically called, is greater than in Sailing Vessels, this plan of fastening is of the greatest Importance, as they can at any time screwed any degree of tightness.

A fine antique Wm. Pearson calendar shelf clock with an fusee movement, with continuous worm and bevel gear drive for the calendar mechanism, square silvered dial with an outer time chapter ring and three inside dials, made by Wm. Pearson, Solway Foundry, was featured in a clock price guide, here. An odd product for a foundry, but perhaps not inconsistent with the sale of pressure gauges from the premises.
