Definitions
- Figure 1 of the said drawings, represents lowed and preceded by a dicing tool
- each of the said balls or tools being conlined within one of a series of metallic sockets, (c c and c) which extends beyond the periphery of the rim (d), of the wheels, and is attached to a shank or rod "(e),wh-ich passesand moves through the rim, and another concentric ring (f), arranged between the arms or spokes (g g &c.), as seen in Figure 1.
- Each of the said dicers and polishers is forced or pressed forward by one of several wound helical springs (la 71. &c.), one end of which rests ⁇ against the ring (f,) and the other against a nut (z'), screwed upon the shank (6,), before mentioned.
- the said shanks have each two other nuts (la, Z,) screwed upon them between the nut and the rim of the wheel, the forward nut bearing against the said rim.
- the object of the rear nut (Z), is simply to keep the nut (7c) in position upon the shank, the forward nut being, as it were, a shoulder upon the shank, which, when in contact with the inner side of the rim of the wheel, prevents the dicing or polishing tool, as the case may be, vfrom being pressed forward by the action of the spring upon its shank.
- the wheel thus constructed and provided with dicing ⁇ and polishing 110015, is
- the said wheel is to be revolved by hand or other suitable power, applied thereto, in such manner as convenience may dictate, and the said wheel is to operate in connection with a curved inclined metallic table Gr, as other dicing or polishing wheels do.
- the dicing tools are usually made of lignumvitee or other very hard wood, and require to be sharpened or recut, as often as they become too much worn or dulled by use. For this purpose, it has been customary to remove them from their sockets, and repair them by hand, often at great expense.
- Our improvement in effecting the recutting of them consists in arranging on the top of the curved tablet G, a small frame H, which has a cutting tool m, screwed upon its end adjacent to the wheel, and is confined or adapted to the table Gr, in such manner as tobe readily moved toward, or from the .wheel at pleasure, and thus bring the cutting tool in contact with the dicers as the wheel is revolved.
- the polishers are to be forced back, so as not tocome into contact with the skin upon the table Gyas the wheel is revolved. They may be held back, by inserting small pieces of leather or other suitable-substance between the nuts k, of their Shanks and the rim of the wheel. So,when the polishers'are used, the dicers should be similarly forced or Vconfined back, so as not to come into contact with the leather.
