fingers

23 and 21. A channel shaped carrier 23 is arranged under the forward arm of the ejector 23 and has ears 23 intermediate its ends pivotally secured to the ejector by a horizontal pivot vpin 33. The finger 21 is fixed to the forward part of the carrier 23 to be supported and shifted by the carrier. The nnger 21 is shaped and mounted to be substantially-parallelwith the finger 23. A yoke 3i is provided on the outer or rear end of the carrier 23 and straddles the pin 23. A coiled spring 32 is arranged on the pin 23 to be under compression Y between the Ayoke. 3| and the Vunder side of the ejector 23. During certain phases of the operation the spring 32 urges or pivots the carrier 23 'to cause the finger 21 to grip upwardly against Y the under sides of the cup beads Y.

The means 2| for operating'theejector 20 is timed in synchronism with the other elements of the-machine and serves to move the active end and D and F to the cup assembling and counting then to the cup releasing positions N and O at means 22.

The plunger 15 does not act on the ejected cups X until there has been a sufiicient number of cups delivered to the receiver 44 to causethe stack of cups to protrude from the top of the receiver. The plunger 15 is engageable with the uppermost protruding -cup X and its downward movement subjects the nest or stack of cups X to a slight compression and 21 with the bead Y holds'the cup X against vertical movement soVV that the cup is stripped from the Vdie C when thelatter moves upwardly at operation l0. Following vthis operation the cam surfaces `4| and 42`actjon the roller 40 to swing the ejector tothe position N of Fig. 6 thus moving the cup X into" vertical alignment with the receiver V44.V Downwardmovemen't of die B during operation lfl produces-correspondsuflicient ibo-closely nest the entire series or group of cups delivered to. the receiver 44 during one complete revolution of the wheel 56.

With the cup forming machine in operation the dies A to F, inclusive, perform the cup shaping downward movement of theejector 20'moving the ejector to position OinFig. 6 where the cup X is entered'in the receiver `44. The downward movement of die B to its initial position also results'yin compression" ofthe-"spring 33 so Vthat thecarrier 23 is `pivotedand ,the nnger 21 -is retracted to free the cup bead Y. During ing and bead forming operations outlined above and the cams 4| Aand 42 are continuously operated to control the ejector 20. The operation of the cup ejecting and counting mechanism of the invention considered in conjunction with operation i11 the ca'm surfaces 4Id and 42l'are vin cooperation with' the roller 40 toV hold the ejector 20 in its extended'position and immediately following operation 11' the surfaces Ile and 42 act on the roller 40 to swing the ejector the general series of die operations outlined above y is as follows: When thedie B ismoved up against the die A at operation 2 the cam faces 4|* and 42 are engaging the roller 40 so that the ejector 20 is held in its retracted positionl and the upward movement of the die B is accompanied by Aupward ,movement of the ejector 20 under the action of the expanding spring 33. When the die B moves down a short distance to free theY cup blank at operation 3 the ejector 20 is shifted downwardly a short distance and is brought to the horizontal plane whichwill be occupied by Y the bead Y of the completed cup X. During i these operations2 and 3 suiiicient compression is maintained in the' spring 33 to hold the gripping ejector finger 21 in the down or released position and the ejector 20 remains in its retracted position, the dwelling surfaces 4I and 4la of the cams remaining in cooperation with the roller 40. During operation 4 when the die C is moved downwardly to draw the cup blank fromrbetween the dies A and B the plunger 15 is moved' downwardly as above described, and

.may engage against the previously ejected cupV i X in the event the cup is protruding from the receiver 44. lWhen the die F'moves upwardly to 20 free of the cup X and back tothe position L 'of Fig. 6. The cam surfaces 4I* and 42* retain the ejector 20 in position L or'in this vertical plane until the ejectorfis again swung inwardly at operation 8 of the next cycle or die actions.

yThe cup ejecting means and cup assembling I and counting means V of the invention operate in synchronism with the cup forming dies of the skilled in the art or fall within the scope of the iron the rim portion of the cup X at operation 6 the pawl 59 is operated as above described to advance the Wheel 56.' YIn the event that the previously completed cup X constitutes the last cup of the counted assembly or stack in the receiver 44 the advancement of the wheel 5S brings the pin 68 against the lug 61 to release the iingers 49 so that the entire group oristack of previously completed cups X is dischargedVv from the receiver. During die operation 7 the ejector 20 remains in its retracted position in the plane to be occupied by the cup bead Y. When the dies E and F separate topositions suol. as indicated in Fig. 6 the cam faces 4lb and 42b act on the roller to shift the ejector 20 fromvthe retracted position above mentioned to the position M of Figs. 1 and 6 where the fingers 26 rand 21 are ready to grip the bead Y. Duringrthe die operation 9 when the dies F and D move downwardly the compression on the spring 33 is relieved and the gripping ejector finger 21 is actuated by the spring 32. This bringsthe finger 26 into engagement with the under side of the bead Y and the bead is clamped between the

fingers

26 and 21. Fig 3 of the drawings illustrates the positions of the dies at this time and shows the
