Abstract: 10,904. Mansell, Hunt, Catty, & Co., Thrower, A., and Petersen, C. June 1. Stamping. - Relates to improvements in machines for making pleated paper capsules for bottles, soufflÚ cups, &c. The driving - mechanism is mounted under a bench a, and comprises a countershaft with a driving-pulley and a sliding- clutch, and cams to operate the various parts through spring- returned levers. The clutch is connected to a spring-returned treadle, which keeps the machine running unless the treadle is depressed by the foot. The crimping and pleating mechanism comprises two sets of pleaters E, G, the lowest set being radially pivoted to a rod e<6>, Fig. 4, and the upper set, intermediately spaced, pivoted to a rod H, and having arcshaped slots, through which passes a continuous wire connecting them to a block I sliding on the rod H, its motion being limited in both directions to the required extent. A guide block F fixed to the bench carries a tray C, on which the discs are placed one by one by the attendant, being carried forward to the pleaters E by fingers D connected to a camreciprocated rod d'. Stops d<9> ensure the discs being correctly placed axially. The upper set of pleaters are brought down to the lower by an arm k connected to the rods H, K, the latter being vertically reciprocated by a cam. The two sets are then moved downwards together, causing the pleaters to turn in an upward direction and crimp the capsule. The pleating is effected by a rotary motion through the required arc of the top set of pleaters, imparted by a cam surface on a rod L engaging with a fixed arm l<1> on the rod H. The rod L may be reciprocated by a cam to move in the opposite direction to the rod H, thus increasing the speed of rotation of the latter. The lower set of pleaters are returned to their horizontal position on the up-stroke by the springs e<13>, e<9> and the cap e<7>. The capsules are transferred to the moulding device, Fig. 7, by an arm M pivoted at M<1>, and carrying a palm'piece m, and vibrated at suitable intervals by a cam. The moulding dies are of the shape of the capsule to be made, the upper one n<3> being carried by a spindle N operated similarly to and synchronously with the spindle H, and the lower one being fixed in a block n<5>, which carries a funnel n<6> in which the partially hollowed capsule is placed by the transferring mechanism. A funnel n' sliding on the upper die presses lightly on the capsule just before moulding, and ensures it being concentrically placed, the funnel being raised on the up-stroke by a swaged rim engaging with the upper edge of the die. The upper die is rotated, when in its lowest position, by a ratchet-wheel q<5> on the spindle N engaging with another q<4> on the upper side of a loose pulley q rotated by a belt from the countershaft. During rotation of the die, a wheel p mounted in a lever p<1> is brought against the capsule, forming the required circumferential groove in the capsule and ensuring its removal by the upper die, from which it is removed by the spring-actuated cap r falling on a transferring-plate S operated similarly to M, from which it passes to a suitable receptacle.
