    • 19,553. Hoffman, E., Frist, R. P., Whiteley, C. E. E., Whiteley, W. G., and Whiteley, H. Sept. 14. Bottle necks, making.-Relates to a tool for shaping or finishing the necks of glass bottles &c. so as to form on the outside of the neck devices for engaging with a cap. The central stem B of the tool is shown detached in Fig. 4. The operative parts of the tool consist of mould sections K, which close about the neck and are free to rotate on the stem of the tool, and expanding fingers N, which turn with the tool and act upon the inside of the neck so as to force the glass into the mould. The fingers N turn on pins M fixed in the slotted cylindrical stem B', and move in the slot B . Outwardly-acting springs D normally keep the fingers closed together, but when the grip levers C, C are closed against the pressure of the spring D, the pins C , having reached the ends of the slots N , close the lower extensions of the fingers so as to expand the latter against the glass. The mould sections are, however, first closed by the action of the following parts of the mechanism :-The pins C are connected by links H with a sleeve G. Sleeves F, E, secured together, are free to rotate and slide on the cylinder B', and also to rotate within the sleeve G, which has ball races at its edges. Lugs F projecting from the sleeve F have cam-grooves F , which, when the sleeve F rises as the levers C are closed, force outwards the arms K , and close the mould sections together. The arms K are pivoted at J to a sleeve J free to turn but not to slide upon the cylinder B . A flanged sleeve J forms a gauge or stop for the neck of the bottle when placed within the mould sections. In removing the tool, the fingers close together before the mould sections open.
