No. 28407.—9th September, 1910.—JOHN CHRISTIE SMITH, of Roslyn, Dunedin, New Zealand, Sanitary Engineer and Plumber. Improved heating-apparatus and system of circulation.

Extract from Specification.—I make a boiler with a large heating-surface, but to contain comparatively little water, and run pipes to the places to be heated. These pipes are combined with the flue from the boiler, which passes through them. For convenience the pipes are generally made in several lengths, the water-pipes being connected with union joints, and the flue-lengths that go with them being merely slip joints. In a convenient place, preferably away from the boiler, is a reservoir allowing for evaporation, and so arranged that when desired a damp heat, or otherwise a dry heat, may be obtained from the system. Heat for special purposes may be had also from the system.

[NOTE.—The above extract from the specification is inserted in place of the claims.]
