Description

This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1862 edition. Excerpt: ... viz.: --564, 482, 437, 428, 406, 401, 381, 344, 300, 242, 128; and it may be remarked that some of these did not break at the small hardened part, but across the soft and broad part of the plate, as attested by the specimens exhibited. Several of these pieces, when under heavy strains, were repeatedly struck with a rivet hammer, causing the whole to vibrate, which proved that they were not only hardened, but toughened by the treatment; and still further to test this important point, the strain in two instances was temporarily removed, by raising the weights. The plates were thus bent in the middle, but sprung back on being allowed to do so. 163. A few experiments followed on rivetted joints. Eight of the plates were in the usual soft state, and six hardened. The pieces were all cut from one plate 190 inch thick, and rivet steel, by the same maker, was used. The soft plates, with rivets 56 inch in diameter, broke across at the rivet holes in two instances, with a loss, compared with the solid plate, of 456 and 435 per cent.; whilst the hardened plate, with rivets 68 inch in diameter, and with a load only 159 per cent. less than that borne by the soft whole plate, had one of the rivets cut through the middle--the corner of one plate breaking off, left the other rivet in the remaining whole piece. Five of these experiments, with rivets 43 inch in diameter, were comparatively lost, from the rivets being too small, although larger than those used for iron plates of the same thickness. These are to be considered as mere preliminary experiments, and are only given as such. They are, however, sufficient to show that the hot rivets do not reduce the strength, by affecting the hardness of the plate, which was all they were expected to prove. It will thus..show more
