| TEXT | Are among the most noteworthy of the many interesting manufacturing establishments in the city of New York. They belong to a class of manufactories of which there are but few in this country, and for the novelty of their machinery and the combination of science and practical skill exhibited in the management, are not surpassed, it is believed, by any in the world. The works comprise two distinct manufactories, located in different parts of the city, with a separate salesroom, twenty-five by seventy-five feet, at No. 54 East Thirteenth street. The Shot Tower is situated on part of a block, consisting of thirty-two lots of ground owned by the firm, and extending from Fifty-third to Fifty-fourth street on the East River. This property has a water front of two hundred and fifty feet, with forty feet depth of water, being navigable for the largest craft, and supplying shipping facilities unsurpassed by any site on the East River. The Tower is a magnificent structure, octagonal in shape, one hundred and fifty feet high, thirty-three feet in diameter at the base, and twelve feet at the top, with walls that are four feet in thickness at the lower floor. The prospect from its summit is a very fine one, overlooking, as it does, Blackwell's Island, and commanding an unobstructed view of Astoria, Ravenswood, Hunter's Point, Greenpoint and Brooklyn. The principal manufacturing operations however are carried on in the buildings, 261 and 263 Water street, which are four stories in height, fifty feet wide and one hundred feet deep. It is in these buildings that their celebrated Eagle Brand Shot are manufactured by an entirely new process. Ordinary shot are made by being dropped from the top of a lofty Tower, some two hundred and forty feet, but in their descent they acquire such a momentum that many of the pellets flatten from the force with which they strike the receiver. In LeRoy's factory the shot are dropped but a short distance, and are buoyed up in their descent by a current of cold air which retards their fall to an extent sufficient to prevent their flattening, and renders them almost perfectly spherical drops. In these buildings, also, there is a great variety of novel machinery for manufacturing Lead and Tin Pipe by Hydraulic pressure, and a Sheet Lead Rolling Mill that produces Sheet Lead of a quality that cannot be surpassed. The pipe machines have a hydraulic capacity of six hundred tons, and are the only ones by which pipe can be made from the first pressure, and by which Tin and other hard metals can be successfully worked. Their pipe machines are of the Cornell patent, with the improvements, of which Messrs LeRoy & Co. are sole proprietors. Formerly they used a long core in the end of the Hydraulic Ram, but experience taught them that by this process, owing to vibration, true centres were impracticable. They then abandoned it and adopted the Cornell plan, which places the core in the bottom of the Cylinder, with the Lead around it acting as a support, and as the Lead only is in motion at the point of pressure, the balance being in a quiescent state, there is no possible chance for the core to waver, but the pipe has a perfectly true centre, and is of uniform strength throughout. The pipe is in continuous lengths, from one eighth of an inch to six inches calibre, and is entirely free from flaws, splits and all other imperfections. The vast superiority of the methods employed in this manufacture over the old fashioned processes has so stimulated the demand, that though the firm produced, in 1866, eight millions of pounds, they have been compelled to duplicate their machinery, and are now producing a proportionately larger amount. The works were established by Thomas Otis LeRoy, in 1845. Among his earliest experiments, was the plan which has been recently revived of lining Lead pipe with Tin, but after prolonged investigation he abandoned it. He found that the Tin coating contracts or shrinks more than the Lead exterior, that from the unequal temperature at which the metals melt, the fusion is not perfect, and that ttie Tin lining, being thin, corrodes from the galvanic action of the two metals, aod is unable to resist the force of the water. Mr. LeRoy, however, was the original manufacturer of Pure Block Tin Pipe, and sent specimens to the Great Exhibition in London in 1851, where he was offered large sums to divulge the process by which it was manufactured. In 1855 Mr. Thomas 0. LeRoy associated with him his brother Edward A. LeRoy, and the two now compose the firm. They employ in their works about sixty persons. |
