Page 50 - It is needless, except for a complete record of directions for preparatory work, to call attention to the desirability of having the test, and especially the road test, made under the supervision of a competent person, who is not only familiar with the details of the testing, but also with the proper method of firing and mechanical operation of the locomotive. This is a most important factor, for it is only the clear-headed and able experimenter who is likely to obtain satisfactory work in this most...
Page 63 - A valve placed on a locomotive and designed to regulate the delivery pressure of steam in a steam heating system. It depends entirely upon the elasticity of springs, the pressure of which can be gaged or regulated by screw studs that bear upon one end of the springs. Pressure Retaining Valve. A device by means of which a certain part of the brake cylinder pressure may be retained to aid in retarding the acceleration of a train in descending long grades while the brake pipe pressure is increased after...
Page 42 - A contrivance for coupling or connecting the ends of a pair of brake hose together, so that the air by which the brakes are operated can pass from one vehicle in a train to another. The couplings for train air signal apparatus are similar to brake hose couplings, but are arranged so that they will not couple to them.
Page 76 - The variation in cross-section or weight of more than 2J per cent from that specified will be sufficient cause for rejection, except in the case of sheared plates, 晈hich will be covered by the following permissible variations...

A joint in which a projection on each leg or leaf of a device is inserted between corresponding recesses in the other, the two being connected by a pin or pivot on which they mutually turn. The legs of dividers and the leaves of door hinges are examples of true knuckle joints. The term, however, has been somewhat commonly restricted to compound or universal joints designed to act in any direction.
Page 13 - An alloy of copper and zinc. The term is commonly applied to the yellow alloy of copper with about half its weight of zinc, in which case it is called by engineers yellow brass; but copper alloyed with about one-ninth its weight of tin is the metal of brass ordinance or gun metal. Similar alloys used for the ' brasses ' or bearings of machinery are called hard brass, and when employed for statues and metals they are called bronze.
Page 94 - ... middle of the tread, and shall not be less than three-sixteenths of an inch in the throat. The depth of the white iron shall not vary more than one-fourth of an inch around the tread on the rail line in the same wheel. 4. Wheels shall not vary from the specified weight more than two per cent. 5. The flange shall not vary in the same wheel more than three thirty-seconds of an inch from its mean thickness.
Page 3 - Angle Iron or Angle. A general term applied by makers to iron or steel rolled in the form of an L. but with the corner rounded off somewhat. When the angle is rolled with a sharp interior corner and not rounded off, it is termed a square-root angle.
Page 51 - At the close of the test the height of water in the boiler should be the same as at the beginning, or, if not, the difference, corrected for inclination of the boiler, should be allowed for. During the process of weighing the coal into the sacks numerous samples should be obtained and placed in a covered box, and a final sample of these selected.
