A handle M is providedto operate the screw. Through the crosshead a pin with ajournal fit is provided, on the end of which a block F is fas-tened and kept from turning by a pin H; while through theblock F is passed the rod C, which can be moved so as to suitthe radius of any link, and is held in place by a set screw lower end of the rod C has two jaws, from which are sus-. /trior ior £rT}erif IVhee/Machine for Grinding Links. pended two links J. These links have bolts A, whicli have taperheads, and which also are provided with a taper washer L and anut, to suit any size holes in the different links.

No. 1 indicates the large arborand No. 2 the small one.
