separation and freeing of the lowermost cup from the-bottom of the stack as soon as the escapement members have been withdrawn from belowthe flange of the lowermost cup. I

A- further object is to provide escapement members operable, while other escapement mem-- bers are being withdrawn from the lowermost cupgto project below thefi'angeof the next lowermost cup to: assume support of the stack above the-lowermost cup and to then exert wedging' and rotational eiTorts against the lowermost cupto: positively separate-"such cup from the bottom of the stack after it has been released from "the escapement members.

Another object is to provide subsequentlyoperable escapement members having wedged ends of arcuate extent and adapted to be moved along the upper edge of the lowermost-cup-to wedgeit away from the next cup and to exert frictionaldrag on the cup tending to -cause rotation thereof for easier separation thereof from the next cup sothat after release of the lowermost cup from initial escapement members itwill beentirely tree from the next cup so that it may drop fron rthe dispensing tube without delay.

The dispenser body comprises a tubular cylin drioal-metal trame I having secured thereto in termediate'its ends an annular flange or ring 2. Spaced a distance below this upper ring 2 is a Similar ring 3- surrounding the body I and beingrotatable thereon, it being provided with a laterally extending arm 4 terminating in a vertical finger plate 5. by means of which the'ring may be readily rotated, The ringi may be strengthened and supported by abearing' hub "6; belowthe ring and surrounding and bearing on the body 7 member II. The hubi's vertically supported by a bearing collar 1 secured to the member i; collar'may be detachably secured as by means of screws: 8;

Between the two rings the body lhas the diametr'ally Opposite circumferentially extending slotsoropen spaces 8 and I 0 throughwhichtwosets of escapementmembersmay project forcon troli'ot the passage or cups through the body I. These escapement'membersare supported on the rotatable-lower ring 3 ,--and' I have shown twodiametrally opposite escapementmembers E and E and two other diametrally opposite escapement'members'li) and D. The controliingmembars are hinged or pivoted on the ring I; and are provided with 'carnslots into which p'insextend from the stationary upp'erring 2 so that upon rotation of the ring 3 the controllingmembers will: be operated. V v j Describing first-the construction and operation of the'escapement members E and E", each member is, sis-shown v the form of a: flat 'arcuate plate H resting an the ring 3 and having at its ends the upwardly'extending spacing and guide lugs I 2 and: i2" engaging at their upper ends against the ring 2; Each plate H has the body part a and the tail end b; the taii end receiving a pivot pin l3 extending upwardly from the ring 3, these pivot pins 13 being adjacent to the solid sections of the body" l between the open spaces 9 and I l therein while-the bodies aof the platesare at suchopen spaces for proj-ection therethrough. "The inner edges of the; plate bodies-o engaging below the flanges 'of the cups to be I v v v are bevelled downwardly toprovideledgesd for section on plane VII-Flint.

guided between the rings.

of a link 20 which at its other end is pivoted to a pin 2| extending upwardly from the ring 3; The

pins 21 are adjacent to the pins l3 which pivot the escapement members E and E, the links being above the tail ends of theescapement meme bers E and E and below the tail ends of the escapement members D and D as clearly shownnFieur se, 5 a .7, 7

As shown, the escapement members E and E extend circumferentially from their pivot points and along the ring 3 in clockwise direction while the esscapement membersDvand -D' extend in counter-clockwise direction.

As .best shown in Figure 8,;the. inner flange 18 on each of the plates 16 is cut away and formed to provide a wedge surface 212 with the point of the wedge at the outer end of the plate, the Wedge flange being transversely bevelled on its inner side as indicated in Figure 9. These wedge flanges I are adapted for projection :through the open spaces 9 and lu in the body-I for cooperation with the cups;

The plate H of each-of thelescapement meme bers E and E has anouter longitudinally extend-' members Dand D has two slots, each comprise ing a longitudinally extending section Z6 and anouter diagonally extending section 27- extending therefrom. Depending from the upper ring 2 i are thepins 28 and 28' for engaging in-the slots ment member D while a pair of pins 29' extends from the ring for engagement in therespective slots of the escapement member D Inthe normal positions of the parts, as shownv in Figure 4;, the

pins

28 and 28 are at the inner ends of the slot sections 23 andthe pins 29v and 29' are at the outer ends of the slot sections 21.

The escapement members D and D. arein posi-. tions in which their wedge ends are withdrawn, from the interior of the tube I but, the escape-' ment members E and E are imposition to project their supporting ledges; C into-thetube l for engagement below the flange of the lower-, most cup of the stack of cups supported in thecontaining member I. A spring 30 extending between a pin 3| on the collar 1 and a pin 32" longitudinally extending slots 23 of the escapement members E and E, pass along'the pins 28 and there will be no radial-movementof these During the fore.-

escapement members. Also during the forepart of the rotational movement of the ring, the diagonal slot sections 21 in the escapement members D and D pass along the

pins

29 and 29 respectively so that these escapement members will be swung to project the points of the wedge flanges l8 into position between the flanges of the lowermost cup and the next cup. This primary movement of the escapement members Dand D is a combined longitudinal and radial movement so that the wedge flanges are brought a sufiicient distance between the cup flanges for the delivery members to engage below the flange of the next lowermost cup for support of the stack above the lowermost cup.

During the final rotational movement of the ring 3 the diagonal slot sections 25 of the escapement members E and E engage along the pins 28 and these escapement members are moved outwardly to Withdraw their supporting ledges C from underneath the lowermost cup so as to free thiscup from the escapement members. the final rotational movement of the ring 2 the longitudinal slot sections 26 of the escapement members D and, D pass along the

pins

29 and 29 and the wedge surfaces are moved circumferentially along the top of the flange of the lowermost cup and during such circumferential movement these escapement members are moved radially inwardly, this radial inward movement taking place because the longitudinally extending slot sections 26 are also slightly diagonal as clearly shown in Figure 4.

As the circumferentially extending wedge surface'is also of bevelled or wedge-shaped transversely, the wedge flanges will wedge in circumferentially and radially between the flanges of thetwo lowermostcups and the lowermost cupv will be positively forced away and entirely freed from the next cup. As cups in a stack are intie mately internested they may tend to stick-to eacn other, this being particularly true when the cups are of parafline or otherwise treated paper. However, my improved escapement means will posi-- tively loosen and detach the lowermost cup from the bottom of the stack should the cup fail to fall down by gravity after the initially acting escapement members E and E have been. withdrawn from the cupflange. The circumferential movementof the wedge surface against the top of the lowermost cup will also cause a frictional drag on the cup flange tending to rotate the cup and such rotational movement in conjunction with the axial movement of the cup by the wedge mechanism will assist in quickly separating the cup for discharge'from the stack.

After the discharge of the cup, the ring 3 released for return thereof to normal position by the spring 30, and'during such return movement of the ring, the escapement members D and D will be withdrawn from the flange of the bottom cup of the stack while the escapement members E and E are being brought back into position to take up the support of the stack.

The links 20 which connect the escapement members D and D with the pivot pins 2i will' permit these members to move freely circumferentially and radially under guidance of

thepins

29 and 29.

In order to keep the lowermost cup aligned within the tube I, particularly while the wedge mechanism is coming into engagement with the flanged edge of the cup, the wall of the member I v is extended downwardly into the spaces Sand [0 where the ledges c of the escapement mem-l During.
