ments in chimneys for incandescent gas-burners of that type in which air is admitted into the chimney outside of the mantle.
The objects of the invention are to produce a chimney which may be used in connection with a burner of the well-known type and will increase the efliciency of the burner.
Another object is to reduce the cost of the I attain these objects by the device illustrated in the accompanying drawings, in which Figure 1 is a view in section of an ordinary form of incandescent gas-burner, showing my improved chimney in place. Fig. 2 is a horizontal section taken on the lines 2 2 of Fig. 1 and looking downward. Fig. 3 is a fragment of Fig. 1 drawn on an enlarged scale. Fig. 4 is a section of the chimney-base, taken on the lines 4 4 of Fig. 1. Fig. 5 is a horizontal section, similar to Fig. 2, of a modification.
In all of the views like parts are designated by the same figures of reference.
In the drawings, 1 is a well-known type of burner, having a burner-cap 2 and mantle 3 thereon. Ordinary chimney-supporting clips 4 are provided on the gallery.
The chimney 5 is formed of a transparent area 6 and a base 7, the latter being preferably formed of metal. The transparent portion may be formed of glass or of mica, that illustrated being of the latter material. The metal base is preferably made of one piece of thin sheet metal stamped or spun to the desired shape, and comprises the cylindrical portion 8, adapted to rest upon the gallery and being retained in place by the clips 1. Above the upper end of the clips the base expands, forming a curved portion 9,.and is then bent at right angles to form a ledge 10 to engage with the lower portion of the trans- Openings mantle are formed on the curved part 9 of the chimney-base and are indicated on the drawings by the numeral 11. The openings are preferably made by slitting the metal to form tongues 12, which are' bent inward at the properangle. The edges of the opening .are bent up inward at 13, so as 'to form, in
conjunction with the tongue 12, a converging nozzle of 'funnel.shape,.w-hich will direct the air upon a certain definite portion of the outside of the mantle. I prefer to form the tongues 12 of curved cross-section, as is more clearly shown in Fig. 3, making the upper portion of the openings curved, so that the openings will not be distorted, as would be the case ifthe tongues were not curved. The other edges of the opening may be curved, as shown in Fig. 2, or square, as shown in Fig. 5. When mica is used, it is preferably formed of separate sheets and connected together by strips of metal of S shape, the mica sheets being inserted within the bends of the strips and the latter closed upon them, forming a rigid structure. These metal strips are provided with extensions 14:, which pass through openings 15 in the chimney-base and are bent upward out side thereof at 16, whereby the mica portion is strongly held in engagement with the base. The air drawn in through the openings 11 will be converged and will impings upon acertain definite area of the outside of the mantle.
I find that in practice the efficiency of the burner is greatly increased by the use'of such converging walled or funnel-shaped openings just described. These openings concentrate the currents of air which pass through the openings and cause them to impinge upon a restricted amount of surface of the mantle; but it is to be understood that all of the different currents of air strike the mantle'on the same horizontal plane. I do not know at this time which portion of the mantle should re-.
ceive the blast of air to secure the greatest efliciency, as the point upon which the blast of air impinges varies according to the circumstances and depends upon the position of the parts; but 'I find by experiment that this point seems to coincide with the point of maximum illumination of the mantle.
Having now described my invention, what ings Within the base between such contracted portion and the transparent portion, the said openings being provided With surrounding means for directing the incoming jets of air upon a definite area of the outside of the mantle.
2. An improved chimney having a transparent portion and a metal base, the said metal base having a contracted portion for engagement With the gallery of the burner and Walled openings Within the base between such eontracted portion and the transparent portion, substantially as described.
3. An improved chimneyhavinga transparent portion and a metal base, the said metal base having a contracted portion for engagement with the gallery of the burner, and funnel-shaped nozzle-openings within the base between such contracted portion and the transparent portion, substantially as set forth.
This specification signed and witnessed this 12th day of March, 190%.
