Abstract

22,451. Nesbit, D. M. Nov. 2. Heating buildings; thermostats.- A hot-water heating installation is converted into a steam heating - installation by substituting a steam generator for the hot-water boiler, and by providing each section, or any particular part of the system, with a device for feeding the steam or vapour automatically to each section or part only as it is required, so as to prevent short-circuiting of the steam. The controlling-device may be of any form, such as that described in Specifications Nos. 12,850, 12,852, and 17,801, A.D. 1904. A thermostat h controlling a valve in the supply pipe e may be enclosed in a jacket i into which the return pipe f is led. The jacket may be provided with external and internal strengthening-ribs formed in the manner described in Specification No. 6320, A.D. 1904, [Abridgment Class Boxes &c.]. The lower part of the jacket may lead to a mud box or dirt catcher, such as that described in Specification No. 6938, A.D. 1905, [Abridgment Class Steam generators]. Where necessary, the supply mains may be inclined so that the water of condensation follows the same course as the steam; or a drain connexion k, fitted with a thermostatic valve l, may lead from the supply main to the return main. The discharge of the vacuum pump, to which the jacket i is connected, may be collected in an elevated tank, where the air is separated, and returned to the boiler. In converting systems in which one main serves both for flow and return, the discharge from the radiators may be led to a common return pipe leading to the vacuum pump or condenser. Specification No. 12,944, A.D. 1902, is also referred to.
