Abstract: 25,168. Barnes, J. E. L., [Crown Cork and Seal Co.]. Nov. 19. Stoppering; sealing bottles. - R e - lates to apparatus for applying metal sealing-caps to bottles. Fig. 2 .shows the sealing- head of a treadleoperated machine, in which the treadle reciprocates vertically the arm C carrying the sealing - head A. The sealing-cap F, the rim of which is preferably of cylindrical form, is secured to the bottle by the action of the points R of a series of jaws M, these points crimping or indenting the rim at intervals under the shoulder of the bottle, as shown in Fig. 4. The jaws M have fingers N and projections 0 ; the fingers bear on, or in a recess in, the head K of the pressure plunger G, and the head K is caused to press on the top of the sealing cap F, during the downward movement of the arm C, by the screw cap J in the upper end of the sealing-head A acting through the adjustable spring H on the flanged sleeve P, which bears on the projections 0 of the jaws M. During the latter part of the downward movement of the arm C and the sealing.head, the inclined inner face of the ring T on the lower end of the sealing-bead engages the inclined outer edges of the jaws M, and forces the jaws inwards to cause the points R to secure the cap. When the treadle is released, the sealing-head is raised by a spring. In a modification, the jaws M are cut away more deeply above the points R, to obviate the possibility of the jaws acting on the cap above the shoulder of the bottle, and so avoiding the risk of fracturing the bottle. In another modification, the jaws are provided with springs, which effect the disengagement of the points R from the cap F when the pressure on the sealing-head is releaeed. Fig. 5 shows a power-driven machine, which is constructed to operace simultaneously on twelve bottles, in four sets of three each, four fixed cams d being provided to depress the sealing-heads. When one bottle of a set is being sealed, the next has been sealed and is ready to be removed, while the third is ready to be sealed. The bottles and sealing- heads are carried by the rotating frame U, b, c, which is driven through toothed gearing from the driving-shaft X. The cams d are carried by the plate a, mounted, so as to be capable of vertical adjustment for variously sized bottles, on the standards f. The adjustment of the plate a is effected by screws g, which can be rotated in one direction or the other, as required, through toothed gearing h from the shaft X. The shaft is provided with a hand-lever j, for engaging and disengaging the gearing h. The cams d act through the roller s on the rod r, Fig. 6, and the cushioning-spring t to depress the seating-head, the pressure plunger G being also provided with a spring H. The jaws M, Fig. 2, are replaced by pins k, Fig. 6, mounted in the plunger head K, these pins being forced inwards by the inclined surface of the ring T, to indent the sealing-cap. The sealing-head is raised, when released by the cams, by the spring v, and the plunger G is also positively raised by the pin p in the sealing-head engaging with the upper end of the slot n in the plunger. A pin u in the frame b prevents the rod r and roller s from rotating. relatively to the frame.
