Another object of the invention is to provide 10 a heating system of the above stated character which is clean, convenient, e?lcient and econom and in which the slippage of air past the im pelling means is reduced to a minimum. The intake for the pump is indicated at ‘I, and the outlet therefor is represented by the character 8. 5y From the outlet 8 to the inlet ‘I there is provided the continuous circuit fluid conducting pipe or tube 9 which normally functions to convey ?uid repeatedly through the circulating system. In order that there may be maintained in the sys- 10 tem‘ a proper e?lcient working pressure of ?uid, any suitable type of compressor Ill may be con- v ical, and which requires little or no attention nected in the circuit by means of a supply pipe l2. The compressor preferably includes any suit throughout the cold weather season. Another object of the invention is to provide ‘ able type of pressure regulating valve or device l5 a heating system that may be operated by using - any available type of power, such as electricity, steam, water or wind power. - The foregoing and other objects are attained 20 by the means described herein and disclosed in . ‘the accompanying drawings, in which: Fig. 1 is a diagrammatical view of the heating ’ system of the present invention. Fig. 2 is a longitudinal cross-sectional view of a fluid impelling device, shown in elevation in Fig. l, which device forms part of the systenn Fig. 3 is an enlarged detail view showing one type of heat radiating element that may be uti lized in constructing the heating system. 30 Figs. 4 and 5 are enlarged cross-sectional views showing suggested modes of producing frictional heat in the pipe or coil of a radiator through which the fluid is pumped or circulated. It is well known that a gas or liquid, (any ?uid), - when forced through an orifice or passage that affords resistance to the movement of such fluid, will produce a considerable frictional heat that may be utilized for air conditioning purposes. Several devices heretofore have been proposed 40 for utilization of the frictional heat of air when moved through or past obstructed or uneven sur 13, designed to maintain a predetermined ?uid pressure within the system. To indicate the amount of ?uid pressure, there may be'installed a suitable gauze or meter H. The location of the gauge or meter is considered immaterial to the 20 invention. . The character l5 indicates any accepted type of safety valve adapted to operate for relieving the system of excess pressure which may result under various conditions of operation. The 25 safety valve preferably is piped to a remote outlet. The circuitous ?uid conductor or pipe 9 is adaptedto have included therein one or more heat radiators or generators I6 that may be in stalled at any desired or convenient locations in 30 a compartment or compartments. The radiators may be employed to heat atmospheric air, or as indicated at H, a radiator I8 may be included in a boiler or water heater for supplying hot water without the employment of a separate 35' heater. The inlet and outlet for the water tank‘ or boiler are indicated at H and 20, respectively. The character 2| indicates generally a trap, one or more of which may be provided for removal of loose particles of matter that may enter or 40 be formed in the system. The trap may include faces, but such devices apparently have not en a suitable valve 22, and it may be provided also joyed public approval and adoption for various with suitable magnetic means 23 so as to restrain ' reasons. The prior devices referred to are those disclosed in the patents of Henson 1,366,455, Allen‘ 1,682,102, and Gilroy 823,856. The device of the present invention will readily be found to pos sess many advantages over kindred devices here any particles of metal that would otherwise cir culate through the system and possibly injure 45 some of the working parts. The trap or traps 2| are located preferably at a bend 24 in cir cuitous pipe 9, in such a manner that the inertia of the particles will perform to deposit them in tofore' designed for heating buildings, vehicles, . ‘the trap. and compartments of various kinds. The valve indicated at 25 is adapted to relieve In the drawings, Fig. 1 illustrates the general combination of elements vconstituting a simple the system of excess moisture, and similar valves ' heating system constructed in accordance with. may be included in the system where moisture 50 is apt to accumulate.
