Application filed November 2, 1880. (No model.) Patented in Germany September 23, 1880, in Belgium October 12, 1880, in England Octobcr12, 1850, in France October 12, 1880, in Italy October 12, 1880, in Sweden December 1, 1880, in Austria-Hungary December 11, 1880, and in Spain January 5, i881.

To all whom it may concern:

Beit known that l, EDUARD KtiHLEmre' ofPrussia, German Empire, have in vented im- 'provements in Lamp of which the following is a specification.

The object of this invention is to furnish an im provedlamp which, may be conveniently used in connection with a percussion lightingdevice, also as'a night-lam p, and for similar purposes. The lamp is so constructed thatit can be instantly lightcdand used without the least danger. p

Theinvention consists of a lamp made of a cylindrical reservoir which is provided with a suitable burner and charged with pieces of sponge or other porous material and a volatile hydrocarbon oil. A perforated plate or screen is interposed between the sponge and wick.

It consists, further, of the combination of the cylindrical reservoir with a sliding sleeve and a percussion lighting device which is pivoted to the sleeve and adapted to light the burner of the lamp.

Inthe accompanying drawings, Figure 1 represents a side elevation of my improved lamp; Fig. 2, a vertical central section of the cylindrical reservoir; Fig. 3, a horizontal section of the same; and Figs. 4, 5, and 6 show respectively a vertical longitudinal section, an end view, and a top view, of alamp and its percussion device, adapted as a pocket lamp and lightin g device.

Similar letters of reference indicate corresponding parts.

In the drawings, a represents the cylindrical reservoir of my improved lamp, which is made of the size and shape of a candle and secured to abase or holder, which is in the nature of a candlestick, as shown in Fig. 1. The burner dis secured on to the upper end of the reservoir a and provided with a wick-tube, cl, which extends downward into the reservoir a. The upper part of the reservoir a is separated from the lower part by a perforated plate or screen, b, above which is placed alayer of cotton waddin g in such a manner that the wick of the burner d is kept in contact therewith. The wick is raised or lowered in the wick-tube d bya spurwheel, s. The lower part of the reservoir (1, below the screen I), is filled with pieces of sponge danger of explosion, even when handled by the most inexperienced persons.

1 The upper and lower ends of the reservoir are provided with projectin g'shoulders a,which serve as stops for a sliding sleeve,f,that is preferably guided by a ton gne-and-groove connection, la, vertically on the reservoir The sleeve f is provided with two brackets, 3, one of which is rigidly attached to the sleeve, while the other is preferably hinged thereto at 2', as shown clearly in Fig. 3. The brackets l support a percussion lighting device, g, which is constructed, as customary in the well-known percussion lighting devices, with an interior tape, h, provided at regular intervals with pellets of an explosive substance. The casing of the percussion device g is pivoted to the brackets l of the sleeve f, so as to be swungtoward the burner, as in Fig.2,or away from the same, as shown in Fig. 1. One of the brackets l is hinged to the sleeve, so that the percussion device may be readily removed for replenishing the tape. The shell g vibrates on a stud which is on the fixed bracket 1, and is limited in its vibration by the stud 0, which passes through the slots. The slide or tape-feeder-i is pivoted to stud 0, and its upper end is pressed by a spring, m, against the tape. The spring m is rigidly secured to the shell 9, and its upper end is bent, so that it serves as a hammer to strike and ignite the pellets. At a a teat is formed on the springm, which teat is arranged in such relation to a slot, t, through the feeding-slide i, that when the shell'g is drawn back to the position shown in Fig.1the teat will ride upon the slidei above the said slot. When it is desired to light the lamp the igniter is moved to the proper height and its upper end pressed forward toward the wick. This allows the teat to snap into the slot t and the upper end of the spring-hammer to strike a pellet. backward movement of the shell 9 the slide 2' will'i'eed a pellet up to a position to be struck by the spring-hammer.

For the purpose of lighting the lamp all that is required is to slide the sleeve fin upward direction until stopped by the shoulder a of the burner 01, and to swing then the percussion device g toward the burner, as shown in Fig. 2, by which motion the percussion device is brought into operation, a pellet ignited, and thereby the lamp lighted.

The same arrangement may also be applied to a pocket lamp and lighting device bysimply making the reservoir of U shape, as shown in Fig. 4, and pivoting the percussion lighting deviceg to the side walls of an inclosing-casing. The burner is in this case not detachable, but stationary, and provided with a wick-regulating spur-wheel, s, at one endand with a'removable cap at the other end, through which ihe reservoir a is filled with oil. The construction of the lighting device is exactly the same as before described, the only difference being that it is moved by a button which passes through a slotin the side wallot' the casing, it being taken hold of after opening a hinged cover, which is retained in closed position by asuitable catch device, as shown in Fig. 5.

The percussion lighting device g may be acted upon by a spiral or other spring, which iscompressed when the devicegis thrown to one side, as shown in dotted lines in Fig. 4. On releasing the side button of the lighting device it is thrown by the spring toward the burner, so as to ignite thereby the pellet of the tape and the lamp in a quick and reliable manner.

At every Havinglhus described my invention, I claim as new and desire to secure by Letters Patent 1. A safety-lamp similar in form to a candlestick, composed of an elongated tubular body or reservoir adapted to receive a verticallysliding lighting attachment, a conical burner detachably fastened to the upper end of said tubular body and provided with a central wicktube, and a supporting-plate at the lower end of the body, said body being divided below the' burner by a perforated plate or screen into two parts, the lower part being filled with sponge or other porous material, while the part above the screen is filled with wadding or other material, by which the oil is transmitted from the lower part to the wick, substantially as described.

2. The combination, with atubular reservoir, at, having a burner, d, and an upper shoulder or stop, a, of a sliding sleeve,f, and a percussion lighting device pivoted to the brackets of the sleeve, substantially as described.

3. As an improvement in lighting devicesfor lamps, the combination, with a reservoirand burner, of an oscillating percussion lighting device provided with means for automatically striking the fulminate upon approach of the lighting device to the burnerot' the lamp, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

EDUARD KOHLER.
