tem or apparatus, and a method of heating build
ings having oneor more compartments or rooms,
vehicles, boats, aircraft and the like._
An object of the invention is to provide for
5
heating a building or the like by. the use of means
utilizing the heat of friction of a gas ora liquid,
under pressure or otherwise, forced through a
circulating system including heat radiators.
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.

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

of the particles will perform to deposit them in
