IMPROVEMENT IN SAFETY-EXTINGUISHERS FOR LAMPS.

Specification forming part of Letters Patent No. 157,503, dated December 8,1874; application led J une 27, 1874.

To all whom it may concern Y Be it known that I, GUsTAF F. EDHOLM, of Lake City, in -the county of Wabasha and State of Minnesota, have invented a new and valuable Improvement in Safety-Extinguisher for Lamps; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and gures of reference marked thereon.

Figure l of the drawing is a representation of a front view of my extinguisher for lamps. Fig. 2 is a sectional view of the same. Fig. 3 is a sectional view of the same, and Fig. 4 is a plan view.

This invention has relation to devices for extinguishing the llames of lamps should they be upset, or should gas become ignited in the chimneys. Y

It consists in combining, with an extinguishing-tube which is free to slide up and down on the wick-tube, a vibrating arm, which is acted on by a spring to keep the extinguisher down in its place, and a weight, which is attached to said arm by a cord or chain, and also a bracket, which will support the said weight when the lamp is in or nearly in an upright position, but which will, should the lamp be tilted very much or upset, allow the weight to drop, and thus, by raising the extinguishing-tube, put out the flame.

In the annexed drawings, A designates the bowl of a pedestal-lamp B, the screw-threaded collar thereof, and C the lamp-burner, which parts may be of the well-known construction, as shown. C designates the burnercone, and D the wick-tube, around which latter is an extinguisher-tube, E, which is allowed 'to slide freely up and down, and when down will expose the upper end of the wick, as shown in Fig. 3. The burner is provided with an air or. gas escape tube, a. (Shown in Fig. 3.) On one side of the tube E is fixed an ear, b, through which plays freely the shorter arm of a vertically-vibrating lever, K, which has its fulcrum on the margin of the base portion of the burner C, and which is acted on by a light spring, s, for keeping the tube E down under ordinary circumstances. To the outer extremity of the longer arm oi' lever K a weight, W, is attached by a chain or cord, fn, which weight is suflciently heavy to raise the tube E and extinguish the iiame. J designates an arm, which is rigidly secured to and depends from the screw-threaded neck of the burner C, and to the lower end of which a bracket or horiof which is convex, to receive and keep in place the weight W, having a concave bottom adapted to fit over the convex shelf, as shown in Fig. l, under all ordinary handling of the lamp.

Should the lamp be upset, the Weight W will fall off of its bracket J, and cause the tube E to extinguish the lalne. If, at any time, gas should ignite in the chimney, the flame can be instantly extinguished by depressing lever K.

I am aware that it is not new to :apply to a lamp-burner an extinguisher operated by a suspended weight, so that, whenever the lamp is tipped beyond a certain position, the extinguisher will pass over the llame and put it out.

What I claim as new, and desire to secure by Letters Patent, is-

The tubular extinguisher E, surrounding the wick-tube D, in combination With the cord c, Weight W, shelf J', its rigid connecting-arm J, and the vertically-vibrating lever K, operated by the depressing-spring s, to keep down the extinguisher when the weight is on the shelf, as specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
