Description
H. H. NIELSEN OIL BURNER Filed Jan. 5, 1935 Patented Nov. 5, 1935 UNITED STATES PATENT oFFlcE OIL BURNER Helmuth H. Nielsen, East Foxboro, Mass.
Application January 5, 1933, Serial No. 650,261
1 Claim.
My invention relates to oil burners and has particular reference to the construction of the Wicks thereof.
My invention has for its object to improve the construction and operation of burners of the class described and more especially oil burners such as are used in connection with domestic ranges or heaters.
Oil burners of the class to which my invention relates have heretofore been constructed with a base formed upon its top side with a channel into which the fuel oil was automatically fed durmg the operation of the burner and it has been the practice, heretofore, to provide a fibrous asbestos wick within said channel through which the fuel oil was fed upwardly by capillary attraction to the flame.
My invention consists in constructing an oil burner of the class referred to with a metallic wick consisting of a foraminous strip disposed in an upright position within the channel of the burner base by which the fuel oil is fed through capillary attraction from the lower portion of the channel to the top thereof. In the best form of my invention the upper portion of the metallic foraminous strip is equipped with a strip of noncombustible brous material such as asbestos which is maintained saturated with the oil that travels upwardly on the metallic strip by capillary attraction.
Other features of my invention are hereinafter pointed out.
In the accompanying drawing:
Figure 1 is a central vertical sectional view of an oil burner provided with a wick constructed in accordance with my invention.
Figure 2 is a section on line 2-2 of Figure 1.
Figure 3 is an enlarged sectional detail illustrating my invention.
The illustrated embodiment of my invention comprises a circular burner base I0 formed upon its top side with a circular channel II that is enlarged at its upper end to provide shoulders I2 and I3 and to receive the usual cylindrical sheet metal walls I4 and I5 which are seated upon the shoulders l2 and I3. These walls I4 and I5 are constructed from perforated sheet metal and disposed concentrically to provide between them a chamber or retort I6.
The fuel oil is supplied to the channel II through a supply pipe I'I so that a body of oil is maintained within the lower part of the channel II, as usual, in a well known type of domestic range oil burner.
Within the channel II I provide a circular wick comprising two concentric ringsmade from foraminous sheet material the lower portion only of which is submerged within the body of oil maintained Within the channel I I.
In Fig. 1 the wick is made from a strip of perforated sheet metal I8 which is molded so that it is U-shaped in cross-section, while in Fig. 3 two 5 foraminous metal strips I8d are used each of which is a band of woven wire.
The top of the wick comprises a relatively narrow marginal strip I9 of fibrous material such as asbestos seated upon and secured to the upper portion only of the metallic portion or portions of the wick structure, as by the Wire staples or the like indicated by dotted lines in Fig. 3.
While the burner is in operation the brous strip I9 is supplied with fuel oil from the lower l5 part of the channel Il by the depending foraminous skirt portions of the wick through capillary attraction. That is, the oil Will travel upwardly over the skirt portions of the wick as it is consumed at the top fibrous marginal strip I9. 20 Furthermore, the metal portions of the wick will transmit heat downwardly to the oil within the lower portion of the channel Il with the result that the oil is fed to the flame by the wick in a preheated condition so that it is thoroughly 25 converted into gas and consumed. Also, as the oil moves upwardly along the portions of the skirts which are disposed between the marginal strip I9 and the body of oil within the channel I I the heated skirt must to a substantial extent 30 serve to vaporize some of the oil, which is to be desired.
In Fig. 3 the skirt portions of the strips are shown each closely adjacent to one of the walls of the groove of the burner base so that there 35 will be substantial capillary action between each skirt portion and its wall. Also, by arranging the two skirt portions in close proximity to each other capillary attraction may be occasioned between said portions, as will be well understood. 40
In Fig. 3 of the drawing, which is an enlarged View, the width of the space between the two skirt portions is exaggerated.
What I claim is:
A wick for an oil burner of the character described comprising two parallel annular foraminous metal stripsdisposed vertically one within the other and in close proximity to each other so as to feed a liquid fuel upwardly by capillary attraction when their lower portions are submerged within a body of oil, and a strip of brous refractory material seated upon and secured to the upper portion only of at least one of said strips so that when the wick is inserted in the burner said strip of fibrous material is supported above the level of the body of oil within said burner.
