THE "COMET" WINDMILL
Messrs. Sidney Williams and Co., Rockhampton, exhibited their new Comet windmill, which has been specially invented and constructed by them for pumping large quantities of water from sub-artesian or non-flowing bores. The particular mill shown is capable of watering 1000 bullocks, pumping from a depth ol 500 ft. to 600 ft. A good idea of its construction and wearing parts may be given when we state that the main shaft is 3in. steel, equal in strength to the crank shaft of a first class 6-h.p. portable engine. The arrangement of the vane, which is regulated by three strong spiral springe, gives perfect governing in the highest or most gentle wind, which is a most important feature in windmill construction. 20ft. Comet mills have been tested to work is a breeze of only 4½ miles per hour, which, is almost imperceptible, thus showing their superior quality. Messrs. Sidney Williams and Co., Rockhaapton, will be glad to give fullest particulars of the most suitable plant for any part of Queensland. The only information they require to be furnished with is the number of stock to be watered, depth of the pumping, and the size of the bore casing or well. Besides windmills, Sidney Williams and Co. are general engineers, and have special irrigation plants to suit all conditions, and will be pleased to furnish their general catalogue to any one writing for same. Sidney Williams and Co. have been manufacturing windmills and carrying on general engineering in Central Queensland for about 30 years, and they may be relied upon as sound advisers in all matters in connection with stock watering, either on a large or small scale, and 1 for general irrigating their windmill are very popular in Central Queensland with selectors and farmers and pastoralists.
