We publish above an illustration of an automatic spoke lathe constructed by the Egan Company, of
Front-street Cincinnati, Ohio. This tool appears to have made quite a revolution in the wheel-spoke industry of the United States, for whereas, before its introduction, the output from one machine was 800 spokes a day, the device we illustrate completes about 2400 per day, its recent record performance being 2691 spokes per day of ten hours, and 13,735 in a week of 58 hours. The general arrangement of the machine will he understood from the engraving. The stock is placed between the centres in the upright frames of the machine, beneath and parallel to a former that is driven at the same rate as the stock, the gearing for this purpose being placed on the left-hand side of the machine. The cutter heads are mounted on a travelling carriage running in guides on the main frame, and being moved by a pinion working in a rack as shown. The carriage is extended beneath the main frame, where it travels on a square guide as shown. The cutter heads are driven by belts from the broad-faced pulley mounted at the bottom of the carriage. Means are provided for varying the shape of the spokes cut, and the cutter heads can be brought on to the stock, at any part of their length. One special feature of the machine is the rapid an automatic return of the carriage to the end of the machine, so that the attendant has nothing to do but to remove the finished spoke and replace it by a new blank, an operation performed by the lever and cam shown on the right hand of the engraving. |
