It is perfectly clear, however, that Stephenson had ascertained the fact that flame will not pass through tubes of a certain diameter—the principle on which the safety-lamp is constructed—before Sir Humphry Davy had formed any definite idea on the subject, or invented the model lamp afterwards exhibited by him before the Royal Society.
As to the value of the invention of the safety-lamp there could be no doubt; and the colliery owners of Durham and Northumberland, to testify their sense of its importance, determined to present a testimonial to its inventor. The friends of Sir H. Davy met in August, 1816, to take steps for raising a subscription for the purpose.
In former days, before the invention of the safety-lamp, Simon had known this fierce man, whose business it was to go daily, at the risk of his life, to produce partial explosions of fire-damp in the passages.
No small indignation was expressed by the friends of Sir Humphry Davy at Stephenson’s “presumption” in laying claim to the invention of the safety-lamp. In 1831 Dr.
He liked dukes to dine with him and hear him scatter his audacious criticisms to Sir Thomas or Sir Humphry. They went away astounded by the powers of their host, who, had he not fortunately devoted those powers to their party, must apparently have rivalled Vandyke, or discovered the safety-lamp.
Stephenson’s friends, fully satisfied of his claims to priority as the inventor of the safety-lamp used in the Killingworth and other collieries, held a public meeting for the purpose of presenting him with a reward “for the valuable service he had thus rendered to mankind.” A subscription was immediately commenced with this object, and a committee was formed, consisting of the Earl of Strathmore, C. J. Brandling, and others.
The advertised object of the meeting was to present him with a reward for “the invention of his safety-lamp.” To this no objection could be taken; for though the principle on which the safety-lamps of Stephenson and Davy were constructed was the same; and although Stephenson’s lamp was, unquestionably, the first successful lamp that had been constructed on such principle, and proved to be efficient,—yet Sir H. Davy did invent a safety-lamp, no doubt quite independent of all that Stephenson had done; and having directed his careful attention to the subject, and elucidated the true theory of explosion of carburetted hydrogen, he was entitled to all praise and reward for his labours.
Down this chasm my friend caused himself to be lowered in a 'cage, having first tested the atmosphere by the safety-lamp. He remained nearly an hour in the abyss. When he returned he was very pale, and with an anxious, thoughtful expression of face, very different from its ordinary character, which was open, cheerful, and fearless.
That section of physics which formulates the laws of heat, has taught us how to economise fuel in various industries; how to increase the produce of smelting furnaces by substituting the hot for the cold blast; how to ventilate mines; how to prevent explosions by using the safety-lamp; and, through the thermometer, how to regulate innumerable processes.
Garforth's invention will prove to the safety-lamp. It has been supposed by some persons that explosions have been caused by the fire-trier himself, but owing to his own death in most cases the cause has remained undiscovered. This danger will now be altogether avoided.
