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. 1866 edition. Excerpt: ...of the top. B is a light sheet-iron or tin gasholder-shaped vessel of less diameter, divided into three partitions by the plates C, D, and E (Fig. 65 next page), of less depth than the rim. F is the pipe from the wash-vessel or condenser. G is the pipe leading to the first set of purifiers. H is the outlet or return pipe from them. I is the pipe leading to the meter and gas-holders. These pipes, in the present position of the valve, are all in action. F and G being iu the same partition communicate with each other, as do H and I, for the same reason. When the purifiers have to be changed, the vessel B (Fig 64) is lifted up until the bottom of the partition, at C, clears the pipes, the outside rim remaining immersed in the tar (the stops S on the guide-rods prevent it from being lifted too high), and it is turned partly round until it occupies the position shown by the dotted lines in the plan, Fig. 65. The length of each dot N through which the guide-rods M pass mark this position, and effectually prevent mistakes, for the vessel cannot be turned the wrong way. K and L are the pipes connected with the second set of purifiers, thrown into action and into communication with F and I when the vessel B is shifted to the position shown by the dotted lines in the plan. P is a wooden frame supporting the pulleys and balance-weight Q to assist in lifting the vessel B, which, while in action, is kept from rising with the pressure of the gas by a bolt. The arrangement of valves connected with this part of the apparatus is of consequence. One hydraulic valve is preferable to four or more slide-valves, because if the man whose duty it is to attend to the latter were to shut those leading to the spent purifiers before he opened the others, the consequences...show more
