EXTINGUISHING DEVICE l' `OR LAMPS.

SPECIFICATION forming part of Letters Patent No. 446,361, dated February 10, 1891.

Application filed May 22, 1890. Serial No. 352,702. (No model.)

.To @ZZ whom, t may concern.-

Beit known that I, DEMTEE MUEGULETZ, a subject of the King ot Roumania, residing at Brussels, in the Kingdom of Belgium,have invented a new and useful Improvement in Extinguishing Devices for Lamps, of which the following is a speciiication.

The invention is applicable to either a lamp having an ordinary burner or an Argand lamp, its object being to extinguish the flame whenthe lamp is upset or falls.

In the drawings, Figure 1 is a sectional view of the weight arrangement by which the extinguisher is operated. Fig. 2 is a plan view of the same. Fig. 3 is a sectional view of a moditication, and Fig. 4 a plan of the same. Fig. 5 shows the weight arrangement as adapted to a round burner. Fi g. 6 is a plan of the same. Figs. 7, 8, and 9 show the application of the device to a burner, the latter gure illustrating the devicein action. Fig. l0 represents a sectional view ot' a round burner with an extinguisher combined therewith. Fig. l1 is a sectional view of a round burner, showing a movable detlector with operating means to cause it to extinguish the flame. Fig.l2 is a modification ot the same. Fig. 13 is another modification.

The device consists of a cylindrical casing A, as shown in Fig. 1, on which is screwed a cover C, projecting from which is a small tube which may be threaded at its upper end for attachment to the burner portion of the lamp, as in Figs. 7, S, and 9, or may be secured thereto in Some other way. It will be noticed that the casing is joined to the lamp-burner by` a connection of reduced diameter, as the tube shown, and this leaves sufficient space for the wick to depend from the burner without being cramped or squeezed as it moves upward.

The casing A has a tube B secured to the bottom of same, as shown, which tube serves as a guide to a weight P, loosely fitting in the casing. This weight carries a spindle a, preferably screwed into a bushing b in the head of same, said spindle passing through into the tube B of the casing, which serves to guide it. The weight has a central hole bored or formed of two diierent diameters O o, as shown, so that a shoulder is formed which serves to keep in place a coiled spring r, which has been dropped over thc tube B and is retained in the aperture O. Under normal conditions the spring r is compressed by the weight I), as shown; but as soon as the lamp is much inclined, as in the act of falling over, the inertia of the weight Will'be overcome by the spring, and, the former being raised, the spindle a, connected thereto, will be given a movement, which is utilized, as hereinafter explained, to operate one of the forms of extinguishing devices shown. In the case of a vertical fall of a suspended lamp the spring will similarlyT overcome the inertia of the weight. As soon as the lamp is replaced in its vertical position the weight falls and the extinguisher is removed. In some cases, as shown in Figs. 3 and 4, the Weight P may be provided with two spindles a a, which may operate one or more extinguishing devices, a central rod a', passing into the tube B, being employed for steadying the weight. Vhen the lamp has a central tube running through same, the arrangement shown in Figs. 5 and G may be employed Where the casing A is annular and surrounds said central tube. Itis provided with a cap 'C' and tubes t 15', which are attached to the burner portion of the lamp in a manner Similar to that illustrated infFigs. 7, S, and 9. The Weight P is annular in shape and lits loosely in the casing. It carries the spindles a a. At its bottom it has guiding pins or rods a a', which pass into tubes B B and rest upon and compress a coiled spring 0^. The spindles a, attached to the extinguishing device, may be bent or forked or of any form in case the arrangement of the lamp will not permit them to be straight. In place of using a weight in the interior of which is placed the spring, a plain Weight maybe employed, which will simply rest on a coiled spring placed in the bottom of the case, some what as shown in Fig. 5, or aplate-spring may be employed, the weight, of course, being suitably guided.

The extinguisher may be of various forms, and the form' of Figs. 7, S, and 9 is used as a representative one, othersbeing adapted to operate similarly. It consists of a bent plate p, hinged to the wick-tube and connected by a link K to the spindle a, the pivots being marked on. and l. Then the Weight rises, it

pushes the extinguisher p from the position of Fig. 7 to that of Fig. 9.

TOO

The extinguishers adapted to round burners are shown in Figs. l0, 11, l2, and 13, and in Fig. lO the extinguisher is formed of bent plates p, hinged to the outside of the Wicktube. Each of these plates is a segment of a circle. In .theirnormal position they are open, as shown; but when brought together by the upward movement of the collar y, to which the spindles a aare attached, they close in and completely cover the wick. In Fig. 1l the extinguisher consists of a disk e', carried by a rod s, having a rack on same, which engages with a pinion q, the latter also engaging with a rack cut on the spindle a. This disk z acts as a deiiector and spreads the fiame when the lamp is alight, and when brought down on the wick by the action of the spindle d extinguishes it. In Fig. l2 the rod of disk z is carried by an arrangement of pivote-d levers on the lazytong 7 principle, the iixed point being at u, on stationary rod s. The other end of the lazytong is pivotally connected at c with the spindle a, so that the motion ot' the said spindle a may open and close same, and so move up and down the disk z. In Fig. I3 the extinguisher consists of a casing u inside of the wick-tube, in addition to the outer casing w, each of these being connected by a spindle d, as shown, so that they may be raised up into Contact with the disk z, which in this case is fixed, and so extinguish the flame.

By providing the casing with the weight, the spring, and the connection to the extinguisher and adapting it to be attached to thev screw-threaded shank of the burner, it will be obvious that the device may be attached to burners of various forms without specially forming them in any way, and thus also enabling them to be attached to burners already 1K1 IISG.

Vhat I claim, and desire to secure by Letters Patent, is-

l. In combination, the burner with its extinguisher and screw-threaded shank for attachment to the lamp-body, they weight and spring for operating the extinguisher, a casing for said weight and spring connected to the under side of the screw-threaded shank of the burner and depending therefrom, and the connecting-spindle from the weight to the extinguisher, substantially as described.

2. In combination, the burner, the extinguisher, the casing having the spring, and the Weight havinga spindle connection to the extinguisher, the said casing being joined to the shank of the burner by a connection of reduced diameter, substantially as described. l

, In testimony whereof I have hereunto set.
