Abstract

8843. Pike, J. G. April 23. [Cognate Application No. 12,621, A.D. 1908, dated June 12.] Baths.-In water-heaters for baths &c. comprising upper and lower vessels A, B separated by a non-conducting partition E, the water to be heated fills the vessel A and certain water-jacketed compartments in the vessel B. The heat from a gas burner, Fig. 3, a kitchen boiler n, Fig. 2, or any other heating-device is imparted primarily to the jacketing-water, which transfers it to the water for use. In each of the three forms shown, the water to be heated enters the vessel A by way of a pipe C, flows to water-jacketed compartments F through a down-take K having a U-shaped lower end g, and is delivered through a pipe I leading from the vessel B. The jacketing-water is boiled, and the steam generated passes through a rising pipe and coil L or its equivalent in the vessel A, thereby giving up its heat. The coil L may lead to the atmosphere, Fig. 1, or into the vessel A, Figs. 2 and 3, by way of a siphon end m. As water in the vessel B undergoes very little change by way of addition of fresh water, little or no deposit of fur takes place therein. Loss by evaporation or leakage is made up from the vessel A by way of a down-take K with a curved lower end h. In the form shown in Fig. 1, the down-takes K are separate; in that shown in Fig. 2, a single down-take is provided with two outlets g, h; while in the form shown in Fig. 3, the one down-take forms a jacket to the other. In Fig. 3 the water-jacketed compartments F are shown arranged to provide a zigzag path for the heated combustion products which leads to a chamber u and chimney T passing through the vessel A. The walls F of the vessel B form part of the water-jacketed compartments, and they may be covered by outer water-jackets w connected by pipes t with the vessel A. An inspection plate P, Fig. 2, may be combined with a bellmouthed trap for the down-take K.
