Not illustrated. 1889 edition. Excerpt: ... as wood, and tarred hemp, have been used, but gum or leather is best. These pul-leys should run at high speed, and require correct proportions, and careful balancing. The castings should be of good iron and free from cooling strains, the rims being of deep section and inflexible. It is a singular fact, applicable to these pulleys as well as to nearly all gearing for transmitting power, that its progress has been far behind machinery for generating and applying power. Pulleys of the present kind are often made with their spokes braced by thin webs at the side so as to offer a large sur-face to the air, and act like a fan wheel. The retardation thus caused produces loss of power at high speeds, and is, moreover, clumsy prac-tice, because the lateral strains do not demand such bracing, should be solid and elliptical in section, as shown at a. The dimensions in the following table correspond with good practice, and will be found suitable for general purposes. The spokes Remarks.--The proiortions of flanges are rapidly increased to prevent danger of hreaking in handling the larger pulleys. The angle at e should he thirty to sixty degrees, or one inch in four. The filling requires to he driven in hard in order to resist centri-fugal force. 3f the dimensions 4 and B do not suit for commercial sizes of gum, they can he changed to conform. To find the price of pulleys, well finished, filled with leather or gum, hored to fit, and keys cut: multiplv the sq.re of the diameter hy three, for the price in dollars. For a pulley four feet in diameter:4 X 4 X 2 = $43... Arrangement.--Wire ropes for transmission should not be less than 322 feet in length, unless tension pulleys are employed, and when the length exceeds 302 feet, intermediate pulleys are...
