MINERS SAFETY-LAR/lp.
SPEClI-ICATION forming part of Letters Patent No. 302,878, dated J'uly 29, 1884:.
Application filed February 21, 1884. (Nomodel.) Patented in Germany September 12,1882, No. 23,341.
To a/ZZ whom it rmty concern: y
Be it known that we, CARL WOLF, a subject of the King of SaXony, and a resident at Zwickau, Saxony, and HEINRICH FRIEMANN, a subject of the King of Prussia, and residing at Eisleben, have invented certain new and useful Improvements in Miners7 Safety Lamps, (which have been patented heretofore by the Government of Germany by Letters Patent No. 23,341, dated September 12, 1882,) of
which the following is a speciiication.
Heretofore heavy non-volatile oils and fatty substances have been exclusively burned in miner s safety-lamps, because such oils or fats reduced the danger of explosion. This advantage, however, is counteracted by the fact that whenever the wick is turned up too high so as to cause imperfect combustion, carbonparticles are deposited upon the wire-gauze and become heated to incandescence, so as to ignite the lire-damp on the outside. Numerous accidents have been traced to this source.
The object of our invention is to constructl a miners safety-lamp suitable for the use of volatile hydrocarbon oils. Vhen in a lamp iilled with such volatile oils the wick is turned up too high, the heating of the lamp causes a rapid and excessive formation of vapors', which prevent the entrance of atmospheric air to the burner through the gauze, and soon extinguish the lamp. It is true that n this ease, also, carbon or lamp-black is deposited; but it is not continued suiiciently long to cause danger. rlhe liability of such lamps to be extinguished calls for means to relight them without the necessity of opening` them, so that the miner is not compelled to leave the. mine for the purpose.
Our invention consists of a miners safetylamp for burning light or volatile hydrocarbon oils arranged with a perforated tube around the wick-tube, the interior space of the bowl around the perforated tube being filled with an absorbent.
The invention also consists of a percussion lighting device located in a chamber of the lamp-bowl, and means for operating said lighting device from the outside.
In the accompanying drawings, Figure l proved miners safety-lamp. Figs. 2 and 8 are detail vertical transverse sections of the percussion lighting device attached to the lamp, showing, respectively, the hammer in raised and lowered position. Fig. 4 is afront view of the percussion-lighter, and Fig. 5 a front view of the slide-piece which operates the hammer and feeds the fulminate tape forward.
Similar letters of reference indicate corresponding parts. A in the drawings represents the bowl of a miners lamp, which is provided with the usual appliances of safety-lamps, such as glass cylinder, wire-gauze, Lwc.
B is a screw-cap closing the neck E of the bowl.
H is a round wick-tube, which ts into a corresponding tubular opening of the screwcap B. The lower part of the wick-tube H, inside ofthe bowl A, is surrounded by a larger' recessed or perforated tube, C, which extends downward from the neck of the bowl A. The space between the tube C and the wall of the bowl A is filled with a suitable absorbent, such as cotton or infusorial earth, whereby the accumulation of vapors is prevented and the danger of explosion obviated. A screw, F, passes through a tube, F, projecting upward from the bottom of the bowl, and serves for raising or lowering the 'wicktube. A chamber, D, is formed within the bowl for the reception of the percussion lighting device. (Represented in detail in Figs. 2 to 5.) By this device the lamp can be lighted without opening the same or without compelling the miner to leave the mine for the purpose of relighting an extinguished lamp.
The percussion lighter consists of the following elements: A shell or case, c, a slidepiece, d, guided in slots b of the shell a, a
rod, g, attached to the slide-piece d, and provided with a knob, Z, at the outer end, a tube, o, passing from the bottom of the bowl into the chamber D, and serving as a guide for the rod g, a dog, f, pivoted to the top ofthe slidepiece d, a spring, h, attached to the slidepiece, a spring-hammer, 7s, with notches i i', and a fulminate tape, m, provided with pellets m.
The cud of the tape m is passedalong IOO the innersurface of the back of the shell a, so
. as to present one of the pellets after the other f to the action of the hammer.
Assuming the parts of the percussion-lighter to be in the positions shown in Fig. 3, then by pushing upon the slide-piece d the dog f is turned so as to force the upper end of the spring h against the tape m, pushing it thereby in upward direction. As the dog f leaves the lower notch, t', in the hammer k, the latter is pressed outwardly until the dog f arrives at the upper slot z, when the hammer is suddenly released, so as to strike against the pellet m at the upper end of the shell a, whereby said pellet is ignited and the lamp lighted. When the lamp vis to be lighted again, the slide-piece cl is pulled back by the knob Zinto the position `shown in Fig. 3, the dog yielding without acting on the spring 71, or hammer la. In this position the percussion device is ready for action whenever the lamp has to be relighted again.
Having thus described our invention, we claim as new and desire to secure by Letters Patentl. In a miners safety-lamp, the combination, with a bowl, A,having a chamber, D, cap B, and wick-tube H, of apercussion lighting device located within-thechamberl) of the bowl, and means for actuating said lighting device from the outside of the lamp, substantially as and for the purpose specified.
2. In aminers safety-lamp, the combination, with the bowl A, cap B, wick-tube H, and chamber D, of a percussion lighting device -composed of shell a, slide-piece d, spring.
h, dog f, notched spring-hammer k, guidetube o, and a fulminate tape m, substantially as specified.
In testimony that we claim the foregoing las our invention we have signed our names in presence of two subscribing witnesses.
CARL WOLF. HEINR. FRIEMANN.
