Of these we have various styles, some sufficiently heavy for a six foot mill stone, and to tram by screws. The centre lift part is constructed in same style as the arch-step described above. We have patterns of all lengths of lighter levers, as shown under head of Lighter Levers, which fit over this style of step in same manner as shown, excepting we provide an independent rest for the rear end of the lever and screw for regulating it. This makes a very desirable rig for the lower end of mill spindles in any mill, and are fast taking the place of all others. It obviates the cutting of the bridge-tree or timber on which it rests.

The steel on which the spindle-toe rests and presses sidewise in running is constructed in various ways. In some situations we provide a flat plate, below for taking the downward pressure, and above it a heavy steel ring supported a little above to allow a chamber for the flow of oil around the very extreme lower end of the steel spindle toe. This chamber is free to be supplied with oil from the upper receptacle through holes provided for the purpose. A bearing made with a hardened steel plate below and a ring of good anti-friction metal around the spindle-toe is the most desirable when properly constructed and of suitable metals.
