S. O. OATLIN, OF CLEVELAND, OHIO, AND A. OORBIN, OF ELLENVILLE,

' NEW YORK.

Letters Patent No. 99,289, dated February 1, 1870.

LAMP-EXTING-UISHER.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being bad to the accompanying drawing, forming part of this specification.

This invention relates to a new and usefulimprovement in a device for extinguishing lamps, and trimming the wick, and consists in a sliding sleeve the top end of which is a circle, to serve as a guide in trimming the wick with scissors, and in a hinged extinguisher, which serves as a self-trimmer, as hereinafter more fully described.

The accompanying drawing represents a vertical section of the lamp-burner, showing our device connected with the wick-tube.

Figure 2 is a view of the device detached.

Similar letters of reference indicate corresponding parts.

"- (t represents the wick-tube, b is the wick.

Over the 'wicktube, a sliding sleeve, 0, is placed, one side of which extends upward further than the other, as seen at d. n

e is the extinguisher and trimmer.

This is hinged to the short side of the sleeve 0, as seen in fig..2, at f f.

The bottom of this extinguisher has a projecting lip, g, which acts as a stop when it is drawn back.

The part h of the extinguisher is bent, and forms an angle with the other part, so that when it is thrown forward, as seen in the drawing, it covers the wicktube, and its edge bears against the long,part of the sleeve 0, as seen. When the extinguisher is thrown forward in this manner, it not only extinguishes the light, but it trims the wick or cuts off the crust from the wick, closing in the wick and the wick-tube.

The top of the sleeve 0, and the edge of the extinguisher, are on a circle which is the proper form for a lamp-wick, and when the wick is trimmed, either by the extinguisher or by a scissors, it is left in that form, as the top of the sleeve forms a guide for the scissors.

The extinguisher is operated by means of the wire i, which is attached to the back of the extinguisher, and passes down through the side of the burner, as seen in the drawing.

The extinguisher being hinged to the sleeve, it will be seen, that .when the wire i is crowded upward, the sleeve will slide upward on the wick-tube, and when the wire is drawn back, the sleeve will drop down, and the extinguisher will be thrown back, leaving the top of the wick and wick-tube clear. By cuttingthecrnst from the top end of the wick when the flame is extinguished, the wick is left in good condition for relighting, except occasionally it may be necessary to trim with the scissors.

The advantages of this arrangement are, the wick is trimmed on a circle by means of the self-trimmer, and the guide on the sleeve, and the wick is extinguished and trimmed at a single operation.

Having thus described our invention,

\Ve claim as new, and desire to secure by Letters Patent- In combination with a wick-tubeof a lamp, the sleeve 0, with the circular top d, and the extinguisher and self-trimmer e, constructed, arranged, and operating substantially as and for the purposes herein shown and described.

The above specification of our invention, signed by us, this 4th day of September, 1869.
