Sabine Baring-Gould - Cornish Characters and Strange Events

The distinctive feature of Trengrouse's apparatus consisted of "a section of a cylinder, which is fitted to the barrel of a musket by a bayonet socket; a rocket with a line attached to its stick is so placed on it that its priming receives fire immediately from the barrel"; 9 9 There is an engraving of it in the Annual Report of the Society of Arts for 1821. The life-preserving rocket was exhibited on the Serpentine before the Duke of Clarence, afterwards King William IV, on May 28th, 1819. People looked on as at some firework display, and nothing came of it. whereas a metal mortar could not be conveyed to the cliff or shore opposite the scene of disaster without being drawn in a conveyance by horses, and where there was no road with the utmost difficulty dragged over hedges and ploughed fields by men. Not only so, but a shot discharged by Captain Manby's mortar was liable to endanger life. Wrecks generally happened in the dark, and then the shot would not be visible to those on the wreck. But Trengrouse's rocket would indicate its track by the trail of fire by which it was impelled, and could be fired from either the ship or the shore.

Trengrouse expended £3000 on his experiments, and sacrificed to this one object – that of saving life – his capital, his business, and his health. He cut off the entail on Priske, which had belonged to the family for several generations, and sold it to enable him to pursue his experiments. There was much that was pathetic in his life: there were the long and frequent journeys to London from Helston, four days by coach, sometimes in mid-winter and in snowstorms, with the object of inducing successive Governments to adopt the rocket apparatus, meeting only with discouragement. Nor was this all. After all his own means had been exhausted, he received a legacy of £500 under a brother's will, and this sum he at once devoted to further endeavours with H.M. Government for the general adoption of his rocket apparatus.

The Russian ambassador now stepped forward and invited Trengrouse to S. Petersburg, where he assured him that, instead of rebuffs, he would experience only the consideration due to him for his inventions. But Trengrouse's reply was, "My country first"; and that country allowed him, after the signal services he had rendered to humanity – to die penniless.

His original design was to supply every ship with a rocket apparatus; as vessels were almost invariably wrecked before the wind, the line might the more easily be fired from a ship than from the shore.

Trengrouse once met Sir William Congreve, who also claimed to be the inventor of the war-rocket; and Trengrouse said to him in the course of their discussion, "As far as I can see, Sir William, your rocket is designed to destroy life; mine is to save life; and I do claim to be the first that ever thought of utilizing a rocket for the saving of human lives." 10 10 Trengrouse's apparatus fitted into a case 4 ft. 3 in. long by 1 ft. 6 in. wide.

Trengrouse moreover invented the cork jacket or "life preserver." This was a success, and has never been improved on. It has been the means of saving many hundreds of lives. He also built a model of a lifeboat, that could not be sunk, and was equal to the present lifeboats of the Royal Lifeboat Association in all respects except the "self-righting" principle. It was not until February 28th, 1818, after many journeys to London, and much ignorant and prejudiced objection that he had to contend against, such as is found so usual among Government officials, that Trengrouse was able to exhibit his apparatus before Admiral Sir Charles Rowley. A committee was appointed, and on March 5th it reported favourably on the scheme.

In the same year the Committee of the Elder Brethren of Trinity House reported in high terms on the invention, and recommended that "no vessel should be without it."

Thereupon Government began to move slowly; in the House the matter was discussed and haggled over. One speaker exclaimed: "You are guilty of sinful negligence in this matter, for while you are parleying over this invention and this important subject, thousands of our fellow-men are losing their lives."

At last Government ordered twenty sets of the life-preserving rockets, but afterwards resolved on making the apparatus itself, and paid Trengrouse the sum of £50, the supposed amount of profit he would have made on the order. Fifty pounds was all his ungrateful country could afford to give him. In 1821, however, the Society of Arts pronounced favourably on his apparatus, and presented Trengrouse with their silver medal and a grant of thirty guineas.

Through the Russian ambassador, the then Czar sent him a diamond ring, in consideration of the great advantage his apparatus had proved in shipwrecks on the Baltic and the Black Sea. Even this he was constrained to pledge, that he might devote the money to his darling project.

With these acknowledgments of his services he had to rest contented; but ever the news of lives having been saved through his invention was a solace to an even and contented mind.

Henry Trengrouse died at Helston on February 19th, 1854.

As he lay on his death-bed with his face to the wall, he turned about, and with one of his bright, hopeful smiles said to his son, "If you live to be as old as I am, you will find my rocket apparatus all along our shores." They were his last words; in a few minutes he had passed away.

The rocket apparatus is along the shores at 300 stations, but not, as he had hoped, on board the vessels. He had despaired of obtaining that, yet that is what he aimed at principally.

In April, 1905, owing to the loss of the Kyber on the Land's End coast, questions were asked in the House of Commons relative to wireless telegraphy between the lighthouses and the coast. On that occasion one of the most valuable suggestions was made by a shipping expert, who considered that the Board of Trade should make it compulsory that a light rocket apparatus should be carried by all vessels, so that, when in distress, if near the coast, the crew could send a rocket ashore. This marine engineer said: "On shore the rockets must be fired by practised men, such as coastguards, because they have to strike a small object; but on a vessel they have only to hit the land, and if people are about, the line will quickly be seized and made fast. At present, too, horses and wagons have to be used, and sometimes it is difficult to find a road leading down to the spot from which help must be rendered. Probably for twenty pounds an appliance could be kept on board a vessel which would send a line ashore in less time and with more certainty than at present. When a vessel is being blown ashore, I have seen rockets fired from the land return like a boomerang to the cliff on account of the strength of the gale. In my judgment, mariners should assist in their own salvation."

On this Mr. H. Trengrouse, grandson of the inventor, wrote to the Cornishman , 24th April, 1905: —

"Your suggestion in the Cornishman of the 15th instant … that all vessels should be compelled by the Board of Trade to carry this apparatus, is very practical, and should, and I trust may, be soon adopted.

"It may interest your readers to learn that the inventor, my grandfather, the late Mr. Henry Trengrouse, of Helston, urged this upon successive Governments without any encouragement whatever, and I on two occasions have also suggested it to the principals of the Marine Department of the Board of Trade, who have informed me of a strong opinion always entertained, that on the occasion of wreck, there would probably not be any one on board possessing sufficient knowledge of the use of the apparatus to render it of any value; which seems very strange indeed, and might be readily obviated by, at least, the captain and officers of vessels being instructed in its use – surely simple enough. My grandfather devoted much time to make it so; and the advantage of an appliance for use on board is so palpable, and the loss of life during many years by its absence so considerable, that it is extremely gratifying to observe a renewed and increasing interest in the subject, which I hope, Sir, as you state, being so important, may now be kept to the fore.
