Storey Electric Chain Hoist. — In the average shop where belting is employed there is a loss of at least 50 per cent, between the power generated and that which is available for the operation of the tools. Many persons would no doubt contradict this statement, but careful tests prove it to be true. What a contrast is presented in the equipment of factories using electric motors!—a strange absence of shafting, belting and pulleys; instead, small motors directly connected to the different tools, making an equipment not only neater in appearance and one where there is less danger to employees, but also one that is far more efficient—where, when a tool is stopped the coal pile is effected, not the nearest countershaft. One of the many moves in the line of direct-connected apparatus is shown in the chain hoist herewith illustrated, which is a very useful piece of machinery, especially in electric light and power stations, iron and steel foundries, factories, etc., and for handling heavy freight. This is one of the products of the Storey Motor & Tool Co. of Philadelphia, and the type illustrated is of 10,000 pound capacity. This hoist is operated by a five horse power motor and will lift 10,000 pounds 5½ feet per minute and lighter loads proportionately faster. It will lower at the rate of 10 feet per minute. By means of the reversing controlling box which comprises a part of the apparatus the hoist will raise and lower anywhere within the above speeds at will of the operator. The starting, stopping, regulating and reversing of the motor are controlled by the two ropes shown in the picture, which are connected to a wheel on the reversing rheostat, which is automatic in its action, the current being cut off as soon as the rope is released. |
