Sectional drawing of a steam boiler.
This steam generator was patented in 1859 by Mr. Joseph Harrison of Philadelphia. It consists of a large number of communicating globular iron chambers, cast in sets of four; the ends of each set are machined so that tight joints can be made when several sets are held together by internal tie-rods. In this way the cells are connected into slabs, while by suitable castings and tie-rods a number of these slabs are similarly united to form a complete boiler of the requisite heating surface. This could be regarded as a 'modular' boiler design.
