' i a ysz UNITED LOUIS W. GRISER, OF ST. LOUIS, MISSOURI.
Specification of Letters Patent.
Patented June 29, 1909.
Application filed August 8, 1908. Serial No. 447,503.
T 0 all whom it may concern:
Be it known that 1, Louis WV. Gmsnn, a citizen of the United States, and resident of St. Louis, Missouri, have invented certain new and useful Improvements in Lamps, of which the following is aspecification, containing a full, clear, and exact description, reference being had to the accompanying drawin 's, forming a part hereof.
lWly invention relates generally to lamps, and more particularly to center draft lamps which utilize mantles to increase their illuminating power, and the particular object of my invention is to provide simple means in the upper end of the center draft tube whereby the draft of air through the tube and the air enterin the burner from the outside is properly fec or deflected into the flame issuing from the tubular wick of the lamp, thus causing said flame to burn very evenly, thus maintaining the entire mantle at an incandescent state, as is required for illuminating purposes.
To the above pur oses, my invention consists in certain nove features of construction and arrangement of parts, which will be hereinafter more fully set forth, pointed out in the claim, and illustrated in the accompanying drawings, in Which:
Figure 1 is a side elevation of a lamp constructed in accordance with my invention, with parts thereof broken away, and with the burner and adjacent parts in vertical section; Fig. 2 is a horizontal section taken on the line 22 of Fig. 1; Fig. 3 is a perspective view of the draft spreading device or deflector which is located in the upper end of the draft tube of the lamp.
Referring by numerals to the accompanying drawings: 1 designates the bowl or body of the lamp, which is carried by the usual base 2, and arranged on top of the bowl is the usual burner 3, on which is mounted the glass chimney 4 and seated in the lower portion of the bowl 1 and extending vertically therethrough and through the burner 3 is the usual open-ended center draft tube 5, the upper end of which terminates at a point just above the upper end of the inner tube 6 of the burner and the perforated outside draft inlet ring 7, which surrounds the upper end of the tubular wick 8, which latter is arranged to slide vertically on the tube 5 and is carried by a ring 9 secured to the lower nary construction and form no part of my invention.
The draft spreader and deflector contemplated by my invention comprises a ring 11 which fits snugly within the upper portion of the tube 5 on a pair of lugs or indentations 12; and fixed to a cross bar 13, located on said ring 11, is a standard 14, on the upper portion of which is fixed an imperforate disk 15, and on the extreme upper end of said standard is a perforated disk 16, the latter being slightly larger in diameter than the disk 15.
The disk 15 is so arranged as to occupy a plane just above the plane occupied by the upper ends of the tube 5 and the wick S; and the perforated disk 16 occupies a position just above the disk 15 and within the lower end of the mantle 17, which is supported in any suitable manner immediately above the burner.
l/Vhen a lamp of my improved construction is lighted, the oil travels up the wick 8 by capillary attraction and burns at the upper end of said wick, which upper end, as hereinbefore stated, lies between the upper end of the tube 5 and the upper end of the perforated draft inlet ring 7.
The draft through the center tube 5 passes upward and strikes against the disk 15 and is deflected thereby outward into the flame issuing from the upper end of the wick; and at the same time the outside draft entering the usual perforations in the lower portion of the burner 3 passes 11 ward and through the perforated ring 7 on t 1e outside of the flame, and thus the inner and outer draft combines with the flame at the point of combustion, thus feeding said flame with air on both sides; and, as a result, said flame burns very evenly; and in passing upward strikes against the perforated disk 16 and is deflected thereby outward against the lower end of the mantle 17 and said mantle becoming incandescent provides the desired light.
My improved deflector causes the flame to burn very evenly at the point of ignition, very efficiently distributes the draft of air to the flame, and causes said flame to burn very evenly around the entire lower portion of the mantle, thereby causing the entire mantle to become incandescent, and thus materially increasing the efiiciency of the lamp.
I claim The combination with a lamp having a central cylindrical draft tube, which draft tube is provided on its inner surface With a plurality of inwardly projecting ind nta, tions, of a ring detachably positioned Within the draft tube and supported on said inden- I tations, a cross bar fixed to the ring, a vertisally disposed standard fixed to the cross bar, an imperforate fiat disk having a diameter less than the draft tube secured'to said standard, said imperforate disk being positioned in a plane above the top edge of said draft tube and parallel therewith, and a fiat disk fixed on the upper end of said standard, which flat disk is provided with a series of vertical perforations and is larger in diameter 20 name to this specification, in presence of tWo 25 subscribing Witnesses.
