Show NITRO nitroglycerine GLYCERIN GLYCERINE N E sinea the invention of nitro glycerine about a year ngo ago there h have ave been two or three accidents caused by its explosion in europe and one in new york city at one of the explosions in europe mr nir nobel brother brother of alfred eniobel nobel the inventor was killed the explosion in new york city occurred in may last in n front of the wyoming iio Ilo hotel teli iii in breen greenwich street the box containing the article was brought to the hotel by a german from bremen and left in the baggage room for several weeks where e it was kicked about and used as a stool to black boots on etc one sunday morning while a guest of the hotel was resting his foot upon the box to have his boot blacked he remarked that the box leaked and asked what was in it the servant servant replied he know whereupon an examination took place and an offensive odor issuing from the box it ift was carried out and placed on the curb stone the concussion produced by dropping it on the curb stone caused it to explode and every window in the hotel was broken as well as all the mirrors the rp ort was heard for a distance of three miles es only one person was fatally injured by the accident A subsequent examination proved that the box contained nitroglycerine nitro glycerine but the german who brought it to the hotel was supposed to have been ignorant of its dangerous character alfred noble the inventor of the nitroglycerine nitro glycerine in a circular dated hamburg november ov ember 1865 thus speaks of the accidents that have occurred from its use in europe and of its liability to explode when improperly handled unfortunately it has been often the case that the workmen have treated the blasting oil like water whenever they found that it did not explode by ignition and thus it has happened that leaky tin boxes filled with blasting oil have been soldered that blasting oil mixed with water has been dried in in a kettle on a blacksmiths fire that frozen blasting oil has been placed into drying furnaces and on boilers of sure that cartridges have been charged and provided with fuse in wooden shanties where straw and gunpowder gun powder were spread on the floor with a tallow candle sticking to the wooden partition that blasting oil has been swallowed 0 on account of its sweet taste etc thus making it miraculous that in spite of all this so few accidents have happened by sise it every new invention is liable to have its disadvantages exaggerated and ind its benefits benefit s underrated now the gigantic power and the great advantages in the use of blasting oil cannot be denied hence it only remains to make a prudent and careful use of it and I 1 shall do all in my power to remove the danger by introducing elastic flacks flasks pac Vaschen provided with safety plates which will make its eipl explosion aslop I 1 a matter of impossibility even against the heaviest blows these metal plates melting at degrees celsius boiling point 0 1 nt of vater water N thus thu s preventing the 91 blasting a sting oil from becoming overheated in a closed space to the degree necessary for exploding but allowing it to run out in case of conflagration and bur burn harmless as it will always do in th the open air 1 I constitute myself responsible to furnish the proof before a committee of experts that no accident of any kina kind ean can an happen in transporting find fand gand using my patent blasting oil 1 if th the e means of precaution are employed which I 1 have proposed and further I 1 am convinced that the use uso of my blasting C oil will lessen the accidents which accompany the use of blasting powder experiment N TS MADE IN EUROPE the following experiments were made in enrobe last summer partly to show the difficulty of exploding the nitroglycerine g in any other manner than that patented by the engineer alfred nobel and partly to show that in several meyeral respects the nitroglycerine nitro glycerine is less dan erous than the common blasting power first trial A quantity of nitro gly cerine was poured on a flattened stone a red hot iron bar was then made to wear along the surface of the glycerine ly cerine without igniting it and nally placed into the blantin blasting 9 0 oil 11 1 spread on the stone which after deins warmed took partly fire and bu burned rilet with a flame but without exploding after removing the iron bar some oil remained on the stone second trial A cavity in a stone was filled with nitroglycerine nitro glycerine a burning wood shaving was introduced and on stirring it the nitroglycerine nitro glycerine burned with a flame but without exploding the combustion ceased as soon as the shaving was wa consumed third trial several glass bottles were filled with nitroglycerine nitro glycerine these bottles were thrown with great force from a height against a i rock below belony the bottles were shattered but without however exploding the oil dourth Fourth frial trial on the suggestion of orsome of the gentlemen present who desired desired that the e prece proceeding eding trial should be bere re heated with the nitroglycerine nitro glycerine warmed wormed to a more than or ordinary temperature three bottles filled with this agent were heated in warm water to 50 60 deg celsius or de dez deg fahrenheit these bottles thrown with great force against the rock shattered likewise without causing an explosion of the blasting oil fifth trial A cartridge of tinned iron filled with nitroglycerine nitro glycerine was placed in a kettle with boiling water without producing any result i sixth trial two flacks flasks of tinned iron of the same kind as those used by the nitroglycerine nitro glycerine company filled with nitroglycerine nitro glycerine were packed into a wooden box as is customary iff for warding them after having screwed down the cover this box was thrown from a height of 9 or 10 feet upon the rock below and without any result to make sure of the quality of the ma material aerial used in these experiments a borehole of 10 feet in depth was charged with 3 pounds of the same samo blasting oil the effect of the blast was astonishing the cha eha charging agi ng of the blast was as follows after r having introduced the blasting oil a paper stopper was inserted into the borehole but without touching in g the oil A handful of powder was th then en poured therein the fuse applied and after introducing another small quantity of powder the borehole was nil fil filled ledwith with sand bulletin I 1 improvements IN
