Cotton weaving: its development, principles, and practice . ng. Such engines asthese show a wonderful advance upon those of twenty-fiveor thirty years ago both in construction and economy ofworking.

Steel shafting is to be pre-ferred, as it will transmit from 25 to 30 per cent, morepower than the same weight of good wrought-iron shaft-ing, and this weight avoided there is a corresponding reduc-tion of the cost of driving. Shafts should be well sup-ported, and carried in wide bearings not too wide shafting is more easily kept clean than dull shaft-ing, and so slightly diminishes fire risks by not allowingthe lodgement of cotton down or dust thrown off in theprocesses of working. The pulleys should be of the unbreakable or wrought-iron type which are strong, light to drive, and repairablein the event of accidents occurring to them. An illustra-tion is given of one of these in fig. 194 Where pulleys. CONSTRUCTION OF A WEAVING ESTABLISHMENT. 379 are placed in such a position that there is a probability oftheir being in the way of some requirement or other theyshould be of the kind called split pulleys, so that theycan be removed and replaced with facility. Of late years swivelling shaft bearings have come intoextensive use and favour. This form of bearing is by farthe best and most economical in use at the present time.
