IMPROVEMENT IN LAM Pv-EXTINGUISHERS.

Specification forming part of Letters Patent No. 151,524, dated June 2, 1874; application filed March 19, 1874.

To all whom Iit may concern:

Be it known that I, MICHAEL WAGNER, of Quincy, State of Illinois, have invented an Automatic Lamp-Extinguisher, of which the following is a specification:

' The object of the invention is to provide an automatic arrangement to prevent the explosion of lamps; and consists in providing the wick-tube with a casing having radial depressed arms, which are operated upon by push-rods extending below and provided at their lower extremities with a weight. A cap, conformed to it over the end ot the wick-tube, is'hinged thereto in such rposition that when the casing is elevated the cap is thrown over the wick, extinguishing the lame. The device is further provided with an annular slide so constructed as to permit the action. of the push-rods, and capable, when moved, of preventing their operation.

Figure 1 is a side elevation of a device embodying the elements of the invention. Fig. 2 is a transverse sectional view through the upper part of the wick and sliding tube. Fig. 3 is a detached view of the slide S.

In the accompanying drawings, B is the wicktube, about which lits snugly the tube D, the base of which is attached to the dome E, and has hinged to its upper edge the cap C, arranged to t over the top of the wick-tube B. T is a sliding tube iitting loosely about the tube D, and having the flanges t on its upper sides, so that as the tube T rises the iiange adjacent comes in contact with the lower portion oi' the cap C and throws it over the wick-tube, extinguishing the tia-me. The lower edge of the tube T is provided with the arms F projecting outward and coming downward to the feet II at their bases, which approach in proper proximity to the slide S and opposite and above the upper ends of the arms A, which project above the lower surface of the slide S, and are there provided with the pin a, to prevent them slipping below the slide. The arms A extend downward through the apertures and enter the lamp-globe in the present instance, their lower ends being contracted and provided with the weight W. The slide S consists of an open double disk fitting properly about the neck of the lamp, and arranged to turn thereon. Its lower edge is perforated to permit the operation of the arms A, as well as to allow the exit of gases from the globe ot the lamp, or the re-en trance of any oil that may be forced up through the perforations. The upper edge of the slide is provided with apertures z and solid spaces n, to permit the operation of the arms A, or, when the slide is turned, check the same.

It is obvious that when the lamp is tipped theweight W, swinging, will force up one of the arms A, which, pressing upon one of the feet H, forces up the arm F, elevati ng the tube T, thus closing the cap C over the wick-tube B, and extinguishing the dame.

That I claim as my invention, and desire to secure by Letters Patent, is-

1. The cap C, arranged to tit over the wicktube and operated by the sliding tube T, substantially as shown and described.

2. The cap C, in combination with the`tube T, provided with the arms F and feet H, and operated by the weighted arms A, substantially as shown and described.

3. The slide S, provided with the vents .c and checks n, for the purposes shown and speciiied.
