SPECIFICATION forming part of Letters Patent No. 733,004, dated July 7', 1903. Application filed December 18, 1900.. Renewedllllay 22,1903. Serial No. 158,377. (llo model.)

To ctZZ whom it may-concern: i

residing at 59 Hampden road, Hornsey, London, England, haveinvented certain new and useful Improvements in Oil-Lamps, of which the following is a specification.

it is specially designed duplex lamps.

The object of the invention is to'provide a reliable automatic means of extinguishing the light if the lamp is upset and a simple arfor those known as rangement for putting out the light when the lamp is not required.

The invention consists of providing a simple form of covers for the top of the wicktubes which are controlled by their own weight with or without the use of a spring, the action of which covers is overcome by a 7 strong spring when the lamp is upset or is raised from the table for the purpose of extinguishing the light, this strong spring being placedin or near the base of the lamp.

An external collar or sleeve is attached to part of the mechanism of my invention and is so arranged that if the saidcollar or sleeve is grasped in the hand to lift the lamp the light is not extinguished, but if the lamp is lifted in another way the light is at once put out. A button, thumb-piece, or the like is provided for working the extinguisher when it is desired'to put out the light without moving the lamp. My arrangement for putting oil into the font of the lamp is also an improvement on existing methods, and it consists in carrying from the usual capor fillinginlet a tube, the inner end of which is perforated, of any convenient sizeor shape, but preferably curved in the part which is perforated, so as to almost encircle the'wick or. Thus when the lamp is being filled wicks. the wick is saturated with oil delivered as spray higher up than is the case if the oil is poured into the font in the usual manner. This arrangement obviates the inconvenience arising from a dry wick, which is sometimes the cause of much delay in the lamp burning properly, and insures a thorough saturation of the wick whether the font is filled or not,

the capillary action of the oil having reached knot O. eted, or otherwise securely fastened to a rod l the point of light by the time the font is in this way'filled.

I will now describe the invention with ref- Figure 1 shows a sectional elevation of a l I damp fitted with my improved extinguishing My invention is applicable to all kinds of" table and floor lamps having flat wicks, but

shows a top. sectional view of my iinproved means for filling the font of the lamp" and which consists of a tube extending from the usual filling cap or inlet to close to the wicks, also shown in section, and almost encircling the said wicks, the portion of the filling-tube nearest the wicks being perforated. Fig. 3 shows a complete view of one of the wicktubes and part of the extinguishing appliance as seen from between the wick-tubes.

A A are two pieces of sheet metal which fit close to the wick-tubes D D and slideup and down the same.

13 13 are metal wing-pieces pivoted at B to the lower partof the burner;

H is a central blade or shaft carrying at its upper end the arms F F, which arepivoted thereto at G, and at their other ends they are pivoted or hinged at F F to the wing-pieces B B.

Y is a lever pivoted at Y to the burner of the lamp and connected by the cord X, which passes through the tube W in the font of thelampto the combination cup and collar or-sleeve NP, to which it is fastened by the The collar or sleeve is brazed, riv- Q, which extends either inside oroutside the stems, butpreferably-ouiside, and sliding in E E are the wick-winders.

K is a support for the globe of the lamp, having several raised portions K, (two being shown in the drawings,) upon which the globe rests, the object of these raised portions being to prevent the heat thrown off from the flames into the globe from passing too freelyto the burner.

K is the usual support or clip for holding the chimney of the lamp and is made rigid with the dome of the burner, which is removable. The lower portion of the burner-frame is fitted with an air-distributer 0r perforated burner-gallery c. This may be of any desired shape and is removable, being secured to the oil-font in any desired manner, usually by a screw-thread joint, as shown.

. The action of the extinguishing appliance is as follows: When the lamp is improperly raised or is upset, the spring T thrusts down the rod Q, which draws the cord X and with it the outer end of the lever Y. This lever at its inner end, which passes through the shaft H, raises this shaft, and this action, as clearly shown in dotted lines,raises the sliding pieces A A and simultaneously draws the wing-pieces B B into such a position that the top of the latter meet the top of the sliding pieces over the wick-tubes D D and effectually extinguish the light.

When the light is extinguished by hand, it i may be done either by lifting the lamp by any part other than the collar or sleeve or by simply pulling the cord by the button Z. The lamp may be safely lifted by grasping the collar or sleeve without extinguishing the light.

J shows a cross-bar between the lower ends of the wick-tubes to which an additional feed-wick can be attached.

Rshows my improved filling-tube extending from the usual cap or filling-inlet M to the wicks V V, which it almost encircles, the side of the filling-tube B being perforated nearest to the wicks, as shown at L.

The base of the lamp is preferably weighted, as shown at U.

The cord connecting the lever Y to the collar or sleeve N P may be substituted by alight chain, rod, wire, or the like, and any simple means for adjusting the length of the same may be adopted.

The shape and positions of any of the parts named may be altered from that or those shown in the drawings, provided the principle of my invention is not departed from.

I claim In a lamp, the combination with two wicktubes ofa sliding plate Afor each of such Wicktubes, a plate B for each of such wick-tubes pivoted to the wick-tubes on the side opposite to that on which the sliding plates are located, bent at the top so as to extend over the wick-tubes and meet the end of the sliding plate when such sliding plate is forced beyond the end of the wick-tube and the pivoted plate toward the same, a link F foreach of the wick-tubes pivotally connected with its pivoted plate B by means of a pin F, a sliding slotted rod H pivotally secured to the unslotted end of the links F, a lever Y pivotally supported upon a pivot Y, one end of which passes through the slot of the rod H, an oil-font, a hollow standard S supporting the oil-font, a sliding sleeve P surrounding the standard S, a rod Q located within the standard S connected with the sleeve P by a suitable pin or pins passing through a longitudinal slot in the standard S, a spring T for normally forcing the rod Q out of the base of the lamp, and means for actuating the lever Y connecting the same with the sleeve S, sub stantially'as shown and described.

In witness whereof I have hereunto set my hand in presence of two witnesses.
