Abstract: 101,351. Nordstrom, E. Aug. 31, 1915, [Convention date]. Crown corks,' applying. - In apparatus for making bottle caps and securing them to bottles or other vessels, means are provided for feeding the vessels to and from the cap-applying means, and means operating at a different rate of speed are provided for feeding a different number of vessels from the first-mentioned feeding-means to and from the cap-securing means. The bottles are fed by an endless belt to a rotary conveyer comprising spaced star-wheels 17, Fig. 5, mounted on a vertical shaft. Grippers 39 carried by bars 38 feed the bottles to the capping-mechanism, and grippers 48 carried by bars 47 feed the capped bottles to the crimping-mechanism, the gearing being so proportioned that the bars 38 make two reciprocations for each reciprocation of the bars 47 so that two bottles are capped separately during the time that two capped bottles are conveyed together to the crimping-mechanism. The bars 38 are pivotally mounted on arms 34, 35 geared together, the arms 34 being rigid with arms 32, which are geared together at 40 and mounted in slides working in guides on the sides of the table 5. One arm 32 is connected to a rod 30 operated by a crank 29 on the shaft 25. The bars 47 are pivoted to arms 46 which are pivoted on slides 45 and geared together at 47<a>; and the slides 45 carry interengaging arms 44, one of which is pivoted to a rod 42 operated by a crank on the shaft 22. The hopper 176, Figs. 17 and 18, containing the cork inserts, has a tangential passage 180 with an aperture registering with a shoot 151, from the lower end of which the corks are fed one at a time by a slide 149, Fig. 16, into the path of the plunger 153. The bent end of a slide or agitator 192, Fig. 20, which extends along one side of the passage 180 and serves to aline the corks as they pass into the passage, engages a recess in a block 190 on a shaft 182 rocked by an arm 186 and rod 187 from an eccentric on the shaft 178. The shaft 182 carries a leaf spring 183 which supports at its outer end a plunger 184 co-axial with the shoot 151. The rotary shaft 178 passing through the cupped bottom-plate 177 of the hopper carries a feed-plate 179 and a yoke 193 having pins 194 at the ends of its arms engaging in apertures in a ring 195 which is supported at a slight inclination to the plate 179 by a stud 196. The ring 195 permits only a single layer of corks to be carried round the hopper by a plate 179. After receiving a cork from a plunger 153, the cap is brought over the mouth of a bottle 166, Fig. 4, on the table 5, the bottle being held by pivoted grippers 167 provided with arms 168 which are geared together and one of which is carried by a sleeve having an arm operated by a cam. The cap-applying plunger 203 is actuated by a lever 205 connected by a lost-motion coupling 206 to a rod 209 operated by the levers 107. If a bottle is not presented to the capping-mechanism, a feeler 173 at the lower end of a rod 174 is moved inwards by a spring, whereupon an arm 175 disengages a pawl 66 and throws the cap-constructing mechanism out of gear. The crimping-head is carried by a slide 217, Figs. 3 and 26, reciprocated in a guide 218 by a cam 214 on a shaft 213. The spring-pressed crimping-elements 228, Fig. 21, project through radial slots in a spring-pressed slide 222 carried by a rod 224 which passes through the upper end of a socket 221 carried bv the slide 217. An adjustable nut 225 limits the downward movement of the rod 224. When the socket descends, the member 227 rests on the cap on the bottle and when the slide 222 is brought to rest, spring-pressed plungers 232 are forced down on to the elements 228 causing them to turn about their rounded lugs 229 and crimp the cap. The bottle-clamping levers 236 carried by the guide 218 are normally drawn together in pairs by springs 237 and are provided with interengaging segmental arms 238. Lugs 239 projecting from the front lever of each pair are engaged simultaneously by a bar 240 connected by straps 241 to the slide 217. A conveyer discharges the capped bottles from the machine,
