Abstract: 13,159. Lowman, J., and Bender, F. J. W. June 26. Stoppers, making.-Relates to a machine for laterall y compressing cork disks or washers and inserting them, with or without the addition of paper disks, in metal capsules &c. The disks are contained in a tube 19, and are pushed singly over the upper end of a conical tube 16 by a sliding plate 21, which is reciprocated by a lever 34 operated by a cam on the mam shaft 31. The disk is held above the tube 16 by flat springs 22. The capsules 12 are placed in holders 11 mounted upon tubular spindles 10 carried by a n intermittently rotating table 8, 9. As each holder 11 comes beneath the tube 16, it is raised by a cam-operated lever 13<x>, and the disk 18<a> is forced down into the capsule 12 by a planger 6 operated by a cam on the shaft 31. The plunger 6 is divided into four parts 6<a>, Fig. 7, which engage the walls of the conical tube 16 and are forced together as the cork disk descends and is compressed. Where annular washers are employed, a central spring rod 86, Fig. 8, is embodied prevents the hole from being reduced in diameter. in the plunger. This rod enters the washer, and Upon reaching the capsule, which may have an elevated central portion to occupy the hole in the washer, the rod 86 is forced up against the action of the spring 87. The washer may be secured by spreading or riveting over the raised central portion. The Provisional Specification also states that annular washers may be compressed from within by an expanding plunger. As the table continues to rotate, a rod 62 contained in the spindle 10 is'raised by an incline 63, and pushes the finished capsule out of the holder 11, a fixed guide 64, Fig. 1, knocking it off to one side. The table is rotated by a rocking lever 45, Fig. 1, driven by a cam on the shaft 31 and provided with a spring pawl 41, which engages notches 43 in the edge of the table. When the lever 45 reaches the end of its forward stroke, the end 41<a> of the pawl 41 is struck by a rocking lever 48 operated by a tappet 50 on the shaft 31. The pawl 41 is thus disengaged from the notch 43, and the lever 45 is drawn back by a spring 52. The pawl 41 comes in contact with an adjustable stop 57 at the end of its stroke. Where paper disks are to be inserted in the capsules, they are contained in a tube 66 fitted with an automatically-operated screw plunger 67, so arranged that the top disk is always at about the same level. A curved tube 68, connected by a ball-and-socket joint 79 to an air-pump 70 driven from the shaft 31, is drawn backwards and forwards over a fixed roller 84 by a link 80 having a slot 82 engaged by a pin 83 on a lever 75 actuated from the shaft 31. The parts are arranged so that the pump 70 creates a partial vacuum in the tube 68 when the end of it rests on the top paper disk. The pin 83 then strikes the end of the slot 82, thus drawing the tube 68 over the roller 84, and depositing the end of it bearing the disk in the capsule 12<b>. The return stroke of the pump 70 creates a pressure in the tube 68, which is then moved back over the roller 84, leaving the disk in the capsule 12<b>. The rotation of the table is steadied by a spring 60, which presses a washer 61 against the bed-plate. The capsules may be placed in the holders 11 by hand, or by a modification of the device described for feeding the cork disks.
