Abstract: 359,505. Filling cartons. HERON, F. H., 181, Queen Victoria Street, London.- (Vortex' Cup Co. ; 421, North Western Avenue, Chicago, U.S.A.) April 22, 1930, No. 12408. [Class 125 (ii).] Relates to rotary machines for filling conical paper cups with predetermined quantities of icecream &c. in which the cups are capped by crimping their marginal edges over the caps. According to the invention the cap delivery and securing mechanisms are pivotally mounted on a joint support for transferring a cap to a filled container, and the cap securing mechanism moves the cap at rightangles to the direction of delivery from the magazine. The cap feed and transfer control cam disc 158 is carried on a shaft 7. A cam 160 and roller 161 on the opposite side of the disc 158 controls the rotation of the shaft 149. When a conical cup is carried by the turntable 40 from B to C, Fig. 2, and is filled with ice-cream &c. the control cam 158 coacting with the roller 157 holds the arm 166 and the shaft 149 in the raised position. Thereupon the cam 160 coacting with the roller 161, Fig. 5, actuates the rack 164 to swing the arm over the cap magazine. The control cam 158 now permits the coiled spring 155 to actuate the bar 153 causing the arm 166 and the shaft 149 to be lowered and to centre the cap gripper over an opening in the table 109 which is directly above the cap supply magazine 121 .. 125. A set-screw on a bracket arm 147, Fig. 2, now moves into engagement with a stub shaft 144 causing a bar 145 to be tripped downwardly and thereby operating a chain 132. This elevates a shelf in the cap magazine so that the upper cap is positioned beneath the cap transfer head. Suction from an air pipe 181 now lifts the cap to the cap gripper. Internal springs in the cap magazine prevent the withdrawal of more than one cap. The arm 166 is now raised through the cam 158 and the gripper and cap are raised above the turntable 40 while the table turns and a filled cup moves from C to D. Meanwhile the gripper is swung by the cam 160 and rack 164 over the position D. The cam 158 now permits the coil spring 155 to lower the arm 166 and centre the cap and rim deflecting mechanism thereon. The arm 166 is now further lowered by the spring 155 and the inner end of a pivotal beam 198 contacts with a set-screw 202 causing relative movement between a plunger sleeve 174 and a bracket sleeve 167. This permits a coiled spring 193 to expand and hold the crimping die plate in position. This downward movement of the sleeve 174 also causes the edge of the cup to be turned downwardly over the cap, and the valve 178 to be opened releasing the suction on the cap. The downward movement of the arm 166 now continues while the hood 186 and sleeve 174 are held stationary by contact with the table 40, and the crimping mechanism is operated thereafter. The cap transfer head is now retracted by the cam 158, lever 153, and arm 166 leaving the filled cup in the turntable ready to be advanced to the discharge position E. Filled containers are dropped through the turntable openings 39 into a discharge shoot 205. The cups are fed to the turntable at A, Fig. 2, and move to B and thence to C where they are filled. A valve and plunger mechanism 83 is shown and described for filling the cups.
