Page 84 - Or with 10 ft. fall one gallon of every 14 may be raised to the height of 100 ft., and so in like proportion as the fall or height is varied. Turns in either drive- or discharge-pipe should be avoided if possible. When it is impossible to set the ram without having elbows in the pipes make the elbows as large as may be, so as to place as little obstruction to the free and easy flow of the water as is practicable. These machines are made of iron and brass. The valve and the valve-stem are made of...
Page 66 - ... as last aforesaid. And whereas the sentence and words following are contained in and form part of the said specification, namely, " This being understood, I would now say that I prefer to make the area of such pipes as many times greater than the area of the hollow shafts as is the square root of the distance between the surface of the water to be raised and the said hollow shafts, or thereabouts.
Page 266 - ... packing should be about 1 inch in thickness and calked perfectly tight so that it will hold water of itself without the lead. Just before the packing is driven tightly into Fig. 47. Fig. 48. Fig. 49. Fig. 50. Fig. 51. Fig. 52. Fig. 53. Fig. 54. the hub, the joint should be examined to see that the space around the hub is the same, so that the lead will flow evenly and be of the same thickness at all points, as the expansion and contraction will work an imperfect joint loose much sooner than one...
Page 32 - Fig. 2. The strength of tin-lined pipe is about the same as that of lead pipe, the greater strength of the tin being offset by the lighter weight of the pipe made in this way. Brass Pipe.

When the requisite quantity of water is forthcoming from the ram, operating under a certain fall, it is not judicious to give it more fall, for by so doing the strain on...
Page 58 - To this must be added an extra area to overcome the friction, which is usually taken at 25 per cent. The resistance of friction in the flow of water through pipes of uniform diameter is independent of the pressure and increases directly as the length and the square of the velocity of the flow, and inversely as the diameter of the pipe. With wooden pipes the friction is 1.75 times greater than in metallic. Doubling the diameter increases the capacity four times. To determine...
Page 197 - ... for the reason that the galvanized coating is scarcely ever smooth but often very rough, which roughness holds the dirt so .that it can never be properly cleaned. THE CAST-IRON ENAMELED SINK. This finish of sink is, indeed, a great step in the advancement of sanitary improvements. When made perfectly and used for light work it is all that could be desired, because it is coated with a material which looks well, and is also indestructible against the action of gases or acids. It is also a smooth...
Page 122 - Overflow it water heating and circulating system. The cold water should always enter the boiler at some distance below the point of entrance of the hot water from the water front of the range; the greater this distance the better will be the circulation, and the less time it will take to heat a certain amount of water. The kitchen boiler is simply a storage tank to keep a supply of hot water on hand so that it can be drawn when...
Page 84 - Thus, with a fall of $ feet of every 7 gallons drawn from the fountain, one may be raised 25 feet, or half a gallon 50 feet. Or, with 10 feet fall, one gallon of every 14 may be raised to the height of 100 feet, and so in like proportion as the fall or height is varied. Turns in either drive or discharge pipe should be avoided if possible.
