Frame Details.—The principal features of the frames whichhave been standardized are the pedestals, shoes and wedges. Jone, 190C. AMERICAN ENGINEER AND RAILROAD JOURNAL. 213 and pedestal binder. Since the cylinders, as far as the framefits are concerned, are in duplicate on the five classes, it fol-lows that this portion of all frames is the same and com- IMPROVING THE MACHINE SHOP OUTPUT, By C.

The main frames, of cast steel orwrought iron, are 4% ins. wide and have a depth of the upperrail varying from i\z ins. between pedestalsto 6 ins. over pedestals. The illustration herewith shows the standardpedestal for the main drivers with its differs from the other pedestals only inwidth, being y2 in- wider on either side of thecenter, or an inch total. The strap binder isfinished for %-im draw, and is held by twobolts at either end passing through the simple design of wedge adjustment is clear-ly shown in the illustration. Driving Boxes.—A special design of cast-steeldriving box has been adopted in two sizes, the9% by 12 for main drivers and 9 by 12 forothers. These boxes are used on 143 enginesoutside of the standard classes. The illustra-tion shows the larger box, the other
