This feed mechanism is more particularly adapted for use in connection with drill presses, the differential feed mechanism being employed for the purpose of feeding down the drill spindle during the progress of the drilling operation. The mechanism is intended to be used in lieu of the ordinary stepped pulleys, which have been usually employed in the transmission of power from the main power shaft to the drill spindle feed mechanism.

968,489 Aug. 23, 1910 Centering-machine Robert Milne Rockford, IL Banning & Banning - patent attorneys
This invention is intended primarily for use in rounding off the ends of rods or spindles and thereafter drilling a counter-bored hole adapted to receive the tail stock of a lathe in the subsequent milling or turning of the work. The object of the invention is to facilitate these operations and at the same time provide means whereby the counter-bored holes will be drilled exactly in the center of the end of the rod or spindle, and to provide means whereby the revolving work will be held rigidly and exactly in position to receive the bit during the drilling operation. The invention further relates to the construction and arrangement of the tail stock of the machine whereby bits or tools of different sizes can be alternately thrown into clutch with the tail driving mechanism and positioned to drill, in the end of the work, holes of varying shape or diameter. The invention also relates to the construction and arrangement of the adjustable steady rest which receives and holds the end of the work during the application of the drill thereto.
