Model of a driving wheel for railway engines, devised to prevent slipping when going up inclines. By the use of this wheel the engine may be reduced in weight, and the wheel rendered stronger, whilst it takes no more room than that now in use.
[The power of a locomotive railway engine is available for onward motion only by the bite or grip of the surface of the driving-wheel on the rail, and as the bite is created by the weight upon the wheel, the surfaces in contact being practically smooth, as the weight of the engine is reduced the bite becomes less tenacious, and the power of the engine may be expended in making the driving-wheel revolve without corresponding onward motion of the train. The method exhibited appears to promise to obtain the requisite bite or grip of the driving wheel, or to prevent the wheel from slipping, or from turning round without onward progress, by means independent of weight upon the wheel.—W. H.]
Two pair of couplings for railway carriages, one for luggage and the other for passenger carriages, to prevent the breaking away; they may he used with or without springs, and may be connected to any other carriage or waggon.
Model of a weighing and lifting crane that will weigh and wind in two inches square, without drum or wheels. By this crane it is stated that a man can lift and weigh one ton with more ease than he can half a ton with the common lifting crane.
