PORTABLE HOT-WATER RADIATOR.

Specification of Letters Patent.

Patented Aug. 25, 1908.

Application filed December 15, 1903. Serial No. 185,325.

To all whom it may concern:

Be it known that I, WILLIAM R. KINNEAR, a citizen of the United States, residing at New York, in the Stateof New York, have invented certain new and useful Improvements in Portable Hot-Water Radiators, of which the following is a specification.

My invention has for its object to provide an individually heated radiator which is port able in the sense that it is not fixed by permanent connection with a heating system, the radiator being constructed of sufficiently light structure to permit its removal from place to place.

-My invention will be hereinafter fully described and its novelty particularly )ointed out in the claims, reference being ha accompanying drawings, in which Figure 1 is a perspective view of a complete radiator embodying my present-invention, Fig. 2 is a vertical longitudinal section of a portion thereof on an enlarged scale, Fig. 3 is a horizontal section through the heating unit ofthe radiator on a still larger scale.

Three classes of units are employed in the radiator, to wit: expansion units 1, preferably two in number and located at the ends of the radiator, and which also serve to radiate heat from the circulating medium; simple radiating units 2 which vary in number according to the capacity of the radiator; and a heating unit 3, of which there is preferably but one, located at an intermediate position in the radiator. These units are connected up into a singie structure by upper and lower circulating passages 4 and 5, preferably formed by striking up bosses on adjacent walls of the respective units and uniting said bosses in a suitable manner. When the units employ inner tubes 6 to provide, central air flues, the circulating pasare continued across these air flues by deflecting the opposite walls of each tube inward and uniting them, all of which is fully described in previous applications and Letters Patent in my name.-

8 (Fig. 1) represent; a gas burner by way of illustration which is supplied by a suitable connectionand air mixer 9. located beneath the heating unit 3, and the latter is suitably constructed to provide chambers for the circulating medium (water) and alterr'ating heat flues IQ for the heating gases arisuig from the burner 8. These alternating chambers and-flues are multiplied as may be desired by the use of inner tubes 11 to the The burner 8 is of suitable number. Tubes 1 1 are supported in the heater and connected with the remaining spaces for the circulatmg medium by striking up bosses on the opposed faces 011 the several parts and uniting these bosses as.

already described.

In order to space the walls of the water heating tubes within the heat flue and at the same time to increase the surface from which the circulating medium may receive the heat, bosses 12 are formed upon the walls of the water tubes. Some of these bosses are arranged to project across the heat flues while others are arranged to project across the chambers for the circulating medium.

The radiator constructed as above described ellicient and. economical in operation. It is also convenient for use as it may be readily mounted upon suitable caster legs. The expansion units are open at the top so that the circulating medium evaporates and supplies the desired amount of moisture to the air of the room. The heat flue is also open at the top.

Having described my invention what I claim as new therein is the following:

1. In an individually heated radiator embodying a plurality of connected and intercommunicating units a heating unit comprising an open ended central heat flue, a water chamber surrounding the 'heat 'llue, a narrow water chamber formed of two approximately parallel walls located Within and extending approximately the length of the heat flue, in spaced relation to the walls of the latter, and provided at its top and bottom, on both sides, with circulating and sustaining connections with the; water chamber surrounding the air flue.

2. In an individually heated radiator cmbodying a plurality of connected and inter communicating units a heating unit comprising an open ended central heat flue, a' .water chamber surrounding the heat flue,

and'el' plurality of tubes located within and extending approximately the length of the heat flue in spaced relation to the walls of the latter, and provided at top and bottom with circulatingand suspending connections each with the-other and with both sides of the water chamber surrounding the rheat flue, the-circulating connections of the tubes being horizontally alined.

3. In combination with a radiator comprising a plurality of heat-radiating units, a heating unit comprising an open ended central heat flue, a water chamber surrounding the heat flue, and a plurality of tubes located Within and extending approximately the length of the heat flue, in spaced relation to the walls thereof, and provlded with circulating and suspending connections one with the other and with opposite sides of the surrounding water chamber, both at top andbottom, and constructed with hollow spacing lugs struck up from the metal of the tubes, holding the walls of the different parts, in spaced relation and increasing the surface for the impingement of themedium employed for heating the circulating medium. 7

4. -In a sheet metal radiator a plurality of units united at top and bottom With circulating connections in horizontal alinement one of the Intermediate units comprismg anopen ended central heat flue, a water chamber surand suspending connections with the water a chamber surrounding the heat flue, which said connections are in horizontal alinement with. the connections between the other units.

The foregoing specification signed this 8th day of December 1903.
