SPECIFICATION formingpart Of Letters Patent NO. 562,630, dated June 23, 1896.

Application filed March 30, 1896. Serial No. 585,318. (No model.)

To all whom it may concern:

Be it known that I, JOHN LINES, of lVaterbury, in the county of New Haven and State of Connecticut, have invented a new Improvement in Lamp-Burners; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1, a side view, partially in section, of a lamp-burner embodying my invention; Fig. 2, a sectional view of the wick-tube and gas-tube of a burner, illustrating the extinguisher in the open position; Fig. 3, a similar view showing the extinguisher in the down or closed position; Fig. 4c, a top view of the same parts; Fig. 5, a sectional view of the wick-tube and gas-tube, illustrating the formation of the gas-tube so as to act as a spring for the extinguisher; Fig. 6, a top view illustrating the same feature.

This invention relates to an improvement in flat-wick lamp-burners, and particularly to such as are furnished with an extinguishing device for closing the upper end of the wick-tube when the wick is withdrawn. It is necessary that a stop of some kind should be provided to prevent the extinguisher from turning too far outward. Lamps of this construction are necessarily provided with gastubes which extend upward parallel with the wick-tube.

The object of this invention is to utilize such gas-tube as a stop for the extinguisher; and it consists in the construction hereinafter described, and particularly recited in the claims.

A represents the burner, which may be of any approved construction, formed with a wick-tube B, and a gas-tube G, arranged in the usual manner. The side of the wicktube, adjacent to the gas-tube, is out way at its upper edge, and to that out-away edge is hinged an extinguisher D. The connection is preferably made by forming ears a on the upper edge of the cut-away portion of the wick-tube B, and perforations in the lower edge of the extinguisher through which the cars a may be bent, forming trunnions on the upper edge of the extinguisher will be bent inward forming a flange b, as shown in Figs. 2 and 3, and the lower edge will also be turned inward between the trunnions for1ning a wide tooth (If. The gas-tubes of this class of lamps, and preferably used in connection with this invention, consist of a strip of metal, the edges of which are turned inward forming flanges e, which stand against one side of the wick-tube, which also forms one wall of the gas-tube. As before mentioned, this gas-tube extends upward parallel with the wick-tube and above the cut-away portion thereof and so that its upper end stands in the path of movement of the extinguisher, which prevents its turning outward. The flanges 6 may be slightly sprung out-ward at the upper end, which form springs tending to force the extinguisher inward. If preferred, however, one of the flanges e may be slightly separated from the main portion of the gastube and curved to form a spring-finger as indicated at f, Figs. 5 and 6.

The operation of the device is as follows: hen the wick is raised, its upper end read ily forces the extinguisher upward, so that it in no wise interferes with the upward movement and lighting of the wick, but when the wick is withdrawn it drags upon the tooth d, which tends to draw the upper end of the extinguisher downward and toward the opposite side of the wick-tube, and this movement is accelerated or assisted by the spring of the gas-tube and by the addition of the flange 1) to its upper edge, which increases the weight at that point. Consequently, as soon as the wick is withdrawn, the extinguisher closes the upper end of the tube. It the flange b on the extinguisher is employed, it is not positively necessary that the gas-tube should exert any spring-pressure upon the extinguisher, as it would naturally close by force of gravity, it only being essential that the gas-tube prevents its tipping too far outward and out of line with the wick-tube.

I claiin 1. In a lamp-burner, the combination with the wick-tube and gas-tube thereof, the upper end of said wick-tube cut away upon the side adjacent to said gas-tube, which projects which the extinguisher turns. Preferablyabove said cut-away portion, and an extin-' guisher pivotailiy connected to the upper edge of that side of the wick-tube which was cut away, substantially as described;

2. In a lamp-burner, the combination with the wick-tube and gas-tube thereof, the upper end of said wick-tube cut away upon the side adjacent to said gas-tube which projects above the said cut-away portion, an extinguisher pivotally connected to the upper edge of that side of the wick-tube which was cut away, the said extinguisher formed at its upper end with an inwardly-projecting flange, substantially as described.

3. In a lamp-burner, the combination with the wick-tube and gas-tube thereof, the upper end of said Wick-tube cut away upon the side adjacent to said gas-tube, which projects above said cut-away portion, an extinguisher pivotally connected to the upper edge of that side of the wick-tube which was cut away,

the said extinguisher constructed at its lower edge with an inwardly-proj ecting tooth, substantially as described.

4. In a lamp-burner, the combination with the wick-tube and gas-tube thereof, the upper end of said wick-tube cut away upon the side adjacent to said gas-tube, which projects above said cut-away portion, an extinguisher pivotaily connected to the upper edge of that side of the wick-tube which was cut away, one edge of the said gas-tubeforniinga spring tending to force said extinguisher inward, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing Witnesses.

JOHN LINES.
