Description
Dawson's patent "consists of a spring pressing mechanism constructed and arranged between the fluted roll and table, as hereinafter described, acting to exert its expansive force in one direction against the under side of the fluted roll and in the other against a stirrup, which embraces a saddle resting on the top roll, thus griping or compressing the top and fluted rolls together, instead of weighing the one down upon the other, and thereby relieving the bearing and journals of the fluted rolls from the extreme amount of friction due to said weights and levers, which in railway-heads and drawing-frames frequently exceeds fifty pounds." (Patent Number 235,936)
