AN ADAPTABLE FINISHING AND BUFFING MACHINE FOR rapidly polishing and finishing round, flat or curvedshapes, grinding flue and tube ends, buffing nickelplated parts, such as car fittings and fixtures, the ver-tical abrasive finishing machine, embodying a patented two-belt system of finishing, with an abrasive cloth belt runningat high speed over a heavy corrugated leather cu.^hion belt, is. Vertical Abrasive Finishing Machine a most important development in the art of abrasive mechanical holding device or power feed attachment,the work is held by hand and produces a finished product of asuperior nature, whereas with a mechanical holding deviceand the power feed attachment, the machine becomes auto-matic in operation and its production is limited only l)y theability of the operator to handle the work, which can Ijeperformed by unskilled labor. The Blevney Machine Company. Greenfield, Mass., willexhibit one of its type A-6-14 macliines illustrated here- with, as well as one of its type F horizontal finishingmachines and a type A automatic polishing and finishingmachine with power feed attachment, at .Atlantic City. The machine has a heavy cast iron column, providing thenecessary rigidity for high speed operation. Steel waysare attached to the column, and the sliding frames in whichthe idler pulleys operate travel on these wa
