Abstract

110,869. Hodgkinson, T. March 16, 1917 File blanks, treating.-Apparatus for grinding round and half-round file blanks has a horizontal trough 13 working to and fro under a grinding- wheel C, and fitted within the trough a holder A provided with jaws or chucks a for clamping the tangs of the files D ; it also has rests b, b<1> for supporting the files, and gearing for imparting rotary or oscillating movement to the chucks. The apparatus shown in Figs. 1 and 2 is for treating round files, and the spindles of the chucks a are geared together by wheels a<2> and driven from a shaft F by a chain f and spindle E. The rest b has semicircular notches to receive the files, and the rest b<1> is adapted to move up and down in guides and is supported by levers B', the position of which is controlled by runners B<2> on a stationary part of the machine. In treating half-round files, they may be clamped in pairs one on each side of a rod, which is clamped in the chuck; or they may be secured singly in the chucks, which then have a rocking motion imparted to them by an eccentric on the shaft.
