Description: |
| Note: Early English patents (pre 1916) were numbered by the year and started at patent #1 at the start of each year in January. The patent # used in DATAMP represents the year of issue and the patent #. This patent is #2869 of the year 1886.
This apparatus comprises four coned sectional nuts, each nut consisting of four pieces A, B, C, D, of conical shape and provided with a screw thread on their inner faces. The nuts are connected in pairs and are capable of being simultaneously opened and closed to release and grip the right and left-hand threaded shafts K, L, on which each pair travel. This opening and closing operation is effected by bands or rings I, the inner portions of which are grooved for engaging and sliding upon shaped projections on the sections of the nuts. The two rings I of each pair are connected by links N and a lever R, and the two pairs are connected by a rod S. The two pairs of nuts working on the threaded shafts K, L, can be automatically thrown into and out of action by the extensions T, T of the rod S striking against a stop set on the side of the machine. One of the shafts may have a thread of a much quicker pitch so as to produce a quick return movement of the planing table. |
