Página 178 - RAINBOW PACKING Thousands of Imitators. No Equal. Will hold Highest Pressure. Don't have to use Wire and Cloth to hold Rainbow. Can't blow it out. THE COLOR OF RAINBOW PACKING IS RED Notice our trademark of three rows of diamonds extending throughout the entire length of each and every roll of rainbow packing.

This method of fastening allows of easy removal, and on replacing makes an air-tight joint without the use of additional packing. The efficiency of the casing is demonstrated by the fact that DUSTING PANEL— PATENTED CLEANING PANEL— PATENTED the hand can be held upon the side of the boiler, when steaming, without discomfort, and the stoke hold is always cool. Hinged to the framing at the front and rear of the boiler are large doors, giving...
Página 187 - A steam lance may be inserted through small dusting doors empaneled in the side casing, as shown above, and communicating with the spaces between the rows of tubes. Each opening is covered by a shutter sliding vertically, which can be opened and shut by the lance. As the seat for this shutter is beveled, it tends on falling to wedge itself into position, thereby making an air-tight joint. This panel is used on the 4-inch tube boilers.

Página 186 - ... forming the heating surface. By this arrangement a high furnace temperature is established, which is acknowledged by all authorities to be the essential requirement of boiler economy. The circuitous route which the gases are compelled to follow, in crossing the heating surface three times before exit, causes them to impart to the tubes the greatest possible amount of heat. The distance traveled by the products of combustion in contact with the heating surface is about sixteen feet, hence...
Página 184 - Should a tube be found defective, from whatever cause, it may be renewed or temporarily plugged, as both ends are accessible. All necessary repairs can be made by the ship's staff. The only tools required are a ripping chisel and an ordinary expander, the operation of which is familiar to every engineer. The placing of the steam and water drum horizontal with its center on the...

The circuitous route which the gases are compelled to follow, in crossing the heating surface three times before exit, causes them to impart to the tubes the greatest possible amount of heat. The distance traveled by the products of combustion in contact with the heating surface is about sixteen feet, hence good economy is maintained with high rates of combustion, and a low up-take temperature assured ; the interval for the absorption of heat, so necessary for economy, being longer than...
Página 186 - ... perforated dry pipe to the stop valve. By a roof of light fire tile, supported upon the lower tubes and extending part way over the furnace, the gases evolved from fresh fuel are compelled to flow toward the rear of the boiler, passing over an incandescent bed of coals and under the hot tile roof. As the furnace increases in height approaching the bridge wall, the gases have both space and time in which to mix thoroughly and burn before entering the bank of tubes forming the heating surface....
Página 186 - ... once more up through the spaces between the tubes, and off to the chimney. The water inside the tubes, as it is heated, tends to rise towards the higher end, and as it is converted into steam — the mingled column of steam and water being of less specific gravity than the solid water at the back end of the boiler— rises through the vertical passages into the drum above the tubes, where the steam separates from the water, and the latter flows back to the rear and down again through the tubes...
