John Jones & Sons of St. George's Engine Works, Liverpool
John Jones and Sons of Marine Engine Works, William Street, Liverpool.(1872)
1853 Fitted out some of the first stern-wheel steamers built in this country, shipped them in parts to India
1866 Supplied steam-driven hydraulic hoists to the works of the Mersey Steel and Iron Co, for raising railway wagons. They were lifted 30 ft from a tunnel connecting to a siding served by the Manchester, Sheffield and Lincolnshire Railway. The main hoist was topped by a 20 ft diameter turntable. This rotated as the hoist rose and fell, being guided by rollers in spiral tracks. Automatic cut-outs acted when the hoist reached the top of its travel. From the turntable, the wagon could be sent to the works’ south yard, or across to a traversing table for transfer to another lift, whence the wagon could be passed to the Bessemer plant. 
1866 John Jones died. Presumably the business was carried on by his 3 sons.
1877 Dissolution of the Partnership between John Jones, Charles Jones, and James Jones, as Engineers and Iron-founders, carrying on business at Liverpool, under the firm of John Jones and Sons, so far as regards the said John Jones. Charles Jones and James Jones would continue to carry on the business under the said firm of John Jones and Sons.
1884 Built boilers for the SS Abyssinia at the St George's Engine Works
1891 Advert. For description of works see 1891 The Practical Engineer.
1896 Made floating caissons for Liverpool’s new North Docks. These were more or less ship-shaped, and had a boiler supplying steam for centrifugal pumps driven by single cylinder vertical engines 
1897 Launched paddle steamers Pearl and Ruby. 
John Jones and Sons continued building ship's engines and one steamship 'The Danny' Daniel Adamson in 1903 (which was recently restored to full function; this has one of the John Jones's ships steam engines. The Danny survives on the Mersey river in Liverpool).
Note: RE: Amedeo plate (pictured): The steamship was bought by José Menéndez of Co of Punta Arenas, Chile. In September 1892 the steamship Amadeo arrived in Punta Arenas on its maiden voyage, carrying bricks to build the family home. It was the first of the ships of their property. The Amadeus has been declared a National Monument by the Chilean Government, and his remains are on the beaches of the bay of San Gregorio (Chile), on the Strait of Magellan.
