The actual distance between the tension bars in each case is at least 4greater than the nominal size. We make a line of these machines up to 72,with a maximum pressure of 150 tons on the plunger ; another set from 54 to84 inclusive, with a maximum pressure of 200 tons.

Wm. Sellers & Co., Incorporated, Philadelphia, Pa. 251 Plate No. 42 HYDROSTATIC WHEEL-PRESS.—150 Tons Capacity, Distance between tension bars, 3 ft. 10; capable of putting two wheels onaxle at the same time. Cylinder lined with copper in improved manner. Double-acting bronze pump, arranged with pressure gauge and stop-valve and improvedsafety-valve to prevent overloading. Hooks and elevating screws for wheels andaxles, travelling on tension bar. Resistance beam or post carried upon wheels onthe tension bar, movable to any position, thus acting equally well for pulling offand pushing on. Complete with countershaft, pressure blocks, and full set ofwrenches. 252 Wm. Sellers & Co., Incorporated, Philadelphia, Pa. Plate No. 210.
