RADIATING ELEMENT FOR GAS HEATERS.
Application filed October 21, 1928. Serial no. 142,254.
The invention relates to a new article of manufacture comprising a radiating element for heaters in the form of a rod or stick of porous refractory earthy mate a rial, such as ceramic clay, having a roughened and indented surface, preferably in the form of alternate grooves and ridges, with the marginal edges of the grooves roughly serrated or generally erose, so that,
1cwhen the elements are heated by an impinging gas flame, the roughened surface will develop various and varying degrees of incandescence as compared with the body thereof, thereby producing not only a pleasing effect, simulating burning coals, but also increasing the radiating efficiency of the element.
The invention is illustrated in the accompanying drawings, in which 20 Fig. 1 is a perspective view of one of the elements.
Fig. 2 is a horizontal cross section thereof.
Referring to the drawings, 1 represents the body of the element, which is preferably in the form of a rod or generally cylindrical stick of refractory earthy material, such as ceramic clay, or the like, which may be conveniently formed by extruding the material in a plastic state through a suitable die and in cutting the extruded material into the do sired lengths to form the sticks or rods. .lt is also preferred that the body of the stick or red be porous and, to effect this condition, a suitable amount of combustible material, such as sawdust, or the like, is admixed h the plastic material and is burned away *ing the process of firing or burning the cks or rods.
The surface of the rods or sticks is roughshed and pit-ted throughout to form projections and indentations, and-is also preferably provided with alternating longitudinal rooms and ridges 2 and 3, with the marginl of the grooves roughly and irreguarly serrated or erose, as at i, and the superfal surface of thegrooves and ridges ughcned and indented, these effects being produced by notching or irregularly serratiug the face of the die of the extrusion machine through which the ceramic material is forced, the projections on the face of the die causing the marginal edges of the grooves and the surface of the rod orstick generally to he torn, roughened anindented, which condition is retained and tired permanently in the'finished article, after the same has been'fired.
The sticks out to proper length are assen in any desired relation in a gas heater, and i even be loosely arranged in a grate or eater like loose sticks or logs of wood, so that, when the gas flame, or the products of combustion thereof, impinge the sticks, the latter become highly heated and will radiate the heat. ifVhile the body of the rods or sticks acquire acertain degree of incandescen-ce, which is more or less uniform, the erose "iarginal edges of the grooves and ridges will become more highly incandescent and will vary in the degree of incandescente, as will the roughened and pitted superficial surtiace of the rod or stick, thereby not only producing a highly luminous effect, but also materially increasing the radiating effect of the rod or stick as afwhole.
What I claim is:
'1. A radiating element for gas heaters, comprising a. rod of porous refractory earthy material having an erosely roughened surface.
2. i1 radiating element for gas heaters,
comprising a rod of porous refractory arthy material having a longitudinally grooved and roughened surface.
3. A comprisinga rod of refractory earthy material having irregularly spaced longitudinal ridges and grooves with roughened surfaces and irregularly notched marginal edges.
4;. A radiating element for gas heaters, comprising a rod of refractory earthy material'having longitudinal grooves with cross marginal edges. 7
5. A radiating element for gas heaters, comprising a rod of refractory earthy-material having a roughened and pitted surface and longitudinal grooves with erose marginal edges.
In testimony whereof I affix my signature.
