This invention relates to a closure feeding and transferring device for a closure applying machine.
The invention has for an object to provide a novel and improved closure feeding and transferring device for transferring successive closures from a closure orienting machine to a closure applying machine in a rapid and efiicient manner.
The invention has for another object to provide a novel and improved closure feeding and transferring device of the character specified which is particularly adapted for handling small, elongated lightweight closures in a highly efiicient and superior manner.
With these general objects in view and such others as may hereinafter appear, the invention consists in the closure feeding and transferring device and in the various structures, arrangements and combinations of parts as hereinafter described and particularly defined in the claims at the end of this specification.

In general, the present invention contemplates a closure feeding and transferring device for use in connection with a rotary closure applying machine wherein it is required to deliver successive closures into position to be received by successive closure applying chucks of a continuously rotated closure applying machine. The closure applying machine may be of the type illustrated and described in the United States patents to A. C. Everett, No. 2,082,048 and No. 2,705,101. In such prior machines the closures are supplied in a chute leading from closure orienting apparatus, and successive closures are removed from the chute and presented into alignment with the chucks by individual transfer arms carried by the rotary mechanism and movable along with the chucks. In operation, the chucks are lowered to grip the closures carried by the transfer arms and then elevated to remove the closures from the arms whereupon the transfer arms are rocked out of the way and the chucks are lowered to apply the closures to their respective containers.
In one embodiment of the invention, the present closure feeding and transferring device is particularly adapted for handling small, elongated and lightweight closures, such as household oil can screw caps which cannot be handled in the conventional manner because of their small size and unstable shape. In the illustrated embodiment of the invention provision is made for delivering such closures from the orienting apparatus to a rotary transfer disk arranged to support successive closures in spaced pockets formed in the disk. During the continuous rotation of the disk the closures are carried into alignment with successive closure applying chucks, and provision is made for elevating the closures out of the pockets into a position to be gripped by the aligned chuck for subsequent application to containers. In operation, the small elongated closures can thus be successfully handled in a rapid and expeditious manner. In a modified embodiment of the invention, the present transfer disk is adapted to also handle conventional screw closures delivered from the orienting apparatus for transfer into alignment with and elevation into successive closure applying chucks.
In practice, the closure applying chucks are continuously rotated in a circular path, and in order to allow sufiicient time for elevating a closure out of its pocket in the continuously rotating transfer disk to present the closure into the gripping chuck, provision is made for guiding the pocket in the transfer disk along the radius of the circular path of the chucks for a short distance and for rotating the transfer disk in a manner such as to maintain alignment of a closure pocket with its chuck during the movement of the transfer disk and chuck.
Referring now to the drawings, the invention is herein illustrated as embodied in a machine for applying screw closures to containers, only a sufficient portion of the machine being herein shown so as to enable the present invention to be understood. The construction and mode of operation of the machine, except as hereinafter pointed out, may comprise that disclosed in the United States patents to Everett above referred to and to which reference may be made.
As illustrated in FIGS. 1 and 2, in general, 10 represents a rotary closure applying machine having a plurality of closure applying chucks 12 movable in a circular path and also rotatable on their own axes. In operation, the containers 14 to which the closures are applied are supplied to the machine on a conveyer 16 and are presented into closure applying position in vertical alignment with their respective closure applying chucks 12 by an intake spider 18. During the continuous movement of the chucks in a circular path, provision is made for transferring successive closures 20 by means of a transfer disk indicated generally at 22 into a position to be gripped by successive closure applying chucks 12. The chucks are then moved vertically downwardly when aligned with their containers and are rotated to effect application of the screw closures to their containers. The containers with their closures applied are then guided and transferred from the closure applying machine back onto the conveyer 16 by a discharge spider 24.
The closures 20 are supplied to the transfer disk 22 from closure handling apparatus indicated generally at 26 which may comprise the closure handling and orienting apparatus illustrated and described in the United States patent to Sterling, No. 2,715,978, to which reference may be made. In general, in the operation of such closure handling apparatus, randomly arranged closures are withdrawn from a bulk supply hopper 28 and deposited on an inclined rotary carrier 30 which is arranged to carry the closures into engagement with the beveled marginal edge 32 of a rotary orienting disk 34. The orienting disk is arranged in a substantially horizontal plane, and as the closures are advanced along the edge of the orienting disk, they leave the carrier 30 and are supported between the beveled edge 32 and a cooperating closure supporting rail 36. Those closures assuming a desired predetermined position between the disk 34 and the rail 36 are capable of maintaining their stability and are advanced into a position to be removed for delivery to the closure applying machine. Those closures assuming other than the desired position are incapable of maintaining their stability and are permit-ted to fall back onto the rotary carrier 30 to be again advanced into engagement with the orienting mechanism.
In the embodiment of the invention illustrated in FIGS. 1 to 8, the present device is shown as adapted to handle the small, elongated lightweight screw closures 20. Each closure is provided with a cylindrical base 37 at its open internally threaded end, and with a tapered or conical portion 39 at its upper end, thus providing a shouldered portion 38 defined by the upper end of the base and the lower end of the conical portion. During their passage through the orienting mechanism, the properly positioned closures are caused to be guided open end up with the shouldered portion 38 supported between the beveled edge 32 of the disk 34 and the cooperating guide rail 36 and with the conical portion 39 depending between the disk and the rail to form a line of closures arranged side by side and upside down.
As herein illustrated, in order to convey the relatively small elongated oriented closures 20 from the orienting mechanism to the transfer disk 22, successive closures in the line are arranged to pass under the open receiving end 40 of a pneumatic tube 42 which is arranged to draw the closure upwardly out of the line by suction and to advance the closure through a semicircular curved portion 44 of the tube to deliver the closure to the discharge end 46 of the tube in an upright position with the open end or base portion 37 facing downwardly and in engagement with the upper surface of the transfer disk 22.
As illustrated in detail in FIG. 4, the pneumatic tube 42 is supplied with air under pressure through an angular upwardly inclined passageway 48 formed in an adapter 50 connected about the tube a short distance above the open receiving end of the tube. The pasageway 48 communicates with an opening at the side wall of the tube and is arranged to direct the air toward the discharge end of the tube. The adapter 50 is connected by a line 52 to any usual regulated source of compressed air. At spaced points in the side wall of the pneumatic tube are provided atmospheric openings 54 to permit escape of the air, the open discharge end 46 of the tube also permitting escape of the air.
With this construction it will be seen that when compressed air is directed through the angular passageway 48 toward the discharge end of the tube 42, the pressure at the receiving end 40 is reduced by a Venturi action to cause a closure disposed beneath and in alignment with the receiving end to be drawn upwardly into the tube. The closure thus drawn into the tube is moved into the path of the compressed air stream from the angular passageway 48 to continue its movement around the curved portion 44 and to the discharge end 46 to provide a line of oriented closures one above the other in slightly nested relation in the tube. "In passing around the curved portion, the position of the closure is reversed so that the closures at the discharge end of the tube are arranged right side up with the base 37 at the lower end. In operation, compressed air may be continuously supplied to the tube.
The pneumatic tube 42 is supportted by brackets 56 extending from a rail 58 supported at a downwardly inclined angle from the machine frame. The discharge end 46 of the tube extends through and is supported in an adapter 60 adjustably secured to the machine frame. The upper end of the adapter is provided with a passageway 61 having a fitting 62 connected to a source of compressed air by a flexible hose 64. The tube 42 comprises a transparent plastic and may be formed in sections provided 'with detachable connectors to facilitate clearing of the tube when required. Photoelectric detecting mechanism indicated generally at 66 may be provided for detecting the height of the closures in the tube and which is arranged to discontinue feeding of additional closures into the tube when the height of the closures reaches a predetermined maximum height. As herein shown, the adapter 60 is arranged to support the discharge end of the tube 42 at a slight angle from the vertical. In operation, when the endmost closure is discharged from the angularly arranged end of the tube, it is guided to a substantially vertical position. As a result, the endmost closure is rocked out of alignment with the next successive closure which tends to partially separate adjacent closures from their nested relationship.
As illustrated in detail in FIGS. 5, 6 and 7, the leading end or base 37 of the endmost closure 20 at the discharge end 46 of the tube 42 is supported on the upper surface of the continuously rotated transfer disk 22 in alignment with circumferentially spaced arcuate grooves or recesses 70 formed in the disk. The discharge end 46 of the tube terminates a short distance above the upper surface of the disk, and each arcuate groove 70 is downwardly inclined from the leading end 72 of the groove to the deeper or trailing end of the groove which defines a pocket 74. In operation, as the disk 22 rotates in a counterclockwise direction, as viewed in FIG. 1, the endmost closure 20 is permitted to drop down out of the discharge end of the tube by virtue of the inclined path of the groove 70 to be withdrawn or stripped from the tube when it is fully lowered and deposited in the pocket 74.
In practice, the oriented closures in the tube may be arranged in slightly nested relation with the conical portion 39 of one closure extending partly into the open end of a succeeding closure, as shown, and in order to prevent release of such succeeding closure until after the first closure is withdrawn, the inclined groove 70 is of a cross section at its trailing end such as to provide a barrier for the succeeding closure. Thus, as herein shown, the leading end of the inclined groove 70 is of a width such as to freely accept the base diameter of the closure, and at a point intermediate the ends of the groove where the entire base 37 is lowered to a point below the upper surface of the disk 22, the top part of the groove is narrowed by the inward extension 76 of a relatively thin top plate 78 secured to the disk, leaving the bottom part of the groove the same width as the leading end. Thus, in operation, the shouldered portion 38 of the base passes under the extension 76 permitting the conical portion 39 of the closure to pass through the narrowed portion of the groove, the extension 76 forming a barrier against which the base 37 of the succeeding closure may slide during complete withdrawal of the endmost closure into the pocket 74 at which time the top of the endmost closure is disposed below the upper surface of the transfer disk. The succeeding closure then slidts over the pocket 74 to engage in a succeeding arcuate groove 70 to be withdrawn in the manner described.
From the description thus far, it will be seen that the closure 20 released from the discharge end of the pneumatic tube is permitted to be lowered in an upright position by the inclined surface of the arcuate groove 70. to the deep end of the groove which comprises, in effect, a pocket 73 in which the closure is supported. As shown in FIG. 7, the closure is positioned in the pocket over a suction opening 84 arranged to engage the base 37 of the closure to hold it in an upright position. The suction opening 84 is formed in the upper end of a vertically movable plunger 86 having a small reduced diameter portion defining a button 88 over which the inside diameter of the open end of the closure is engaged and fitted to maintain the closure in an upright position by virtue of the suction applied to the open end of the closure.
In operation, the closures are discharged from the tube by gravity under the influence of the weight of the line of closures in the tube assisted by the effect of the compressed air directed into the tube through the passageway 61. As herein shown, in order to positively guide the endmost closure 20 down into its pocket 74 against the closed end wall thereof and over the button 88, two spring urged guide arms are provided each of which serves to guide the closure in an upright position after it leaves the tube and also serves to prevent displacement of the closure laterally or forwardly out of the pocket during downward movement of the closure whereupon the closure is engaged over the button 88 and held in an upright position by suction. As herein shown, one of the spring urged arms, indicated at 80, is pivotally mounted at 68 in the adapter 60 and is provided with a relatively narrow guide face 82 at its lower end arranged to prevent forward displacement of the closure during lowering thereof into its pocket. In operation the guide face 82 rests on the upper surface of the top plate 78 in alignment with the arcuate grooves or recesses 70, and as the disk is rotated the arm 80 enters the groove and is permitted to rock in a clockwise direction by virtue of the inclined surface of the groove 70 until the arm comes to rest against a stop surface of the adapter to present the guide face 82 in front of the closure and in vertical alignment with the discharge end of the tube to serve as a guide to prevent forward displacement of the closure. The guide face 82 is disposed between the end of the tube and the top of the closure in its fully seated position, and during continued rotation of the disk the face 82 engages the end of the groove 70 to rock the arm 80 up to again engage the upper surface of the top plate 78.
The other spring urged guide arm indicated at 89 is provided with a semicircular engaging or guiding end 91 shaped to fit the circumference of the base 37 and is also arranged in vertical alignment with the discharge end 46 of the tube. The guide arm 89 is arranged to extend into the space between the top plate 78 and the bottom flange 105 of the transfer disk and serves, in effect, as a continuation of the tube to prevent the closure from falling laterally out of the open side of the groove during its downward movement into the pocket. Once the closure is engaged in the pocket over the button 88 the suction opening 84 serves to maintain the closure in an upright position, and during the continued rotation of the disk the arm 89 is rocked out of the path of the closure by the movement of the closure therepast. As herein shown, the arm 89 is carried by one arm 93 of a bell crank pivotally mounted at in a bracket 109 secured to a stationary portion of the machine. The second arm 99 is connected by a relatively weak spring 101 to the bracket 109 and is also provided with a stop screw 103 to adjustably limit the movement of the arm 89.
In order to prevent displacement of the closure from its pocket after the closure is moved past the engaging end 91 of the guide arm, a leaf spring guide 111 is supported to extend into the open space between the top plate and the bottom flange and a stationary curved guide bar 107 also extended into the open space is arranged to continue its support of the closure in its pocket during the further movement of the disk until the suction opening 84 is effective to support the closure. As illustrated, when the closure is fully seated in its pocket, the top of the closure 20 is disposed flush with or slightly below the upper surface of the top plate 78.
As illustrated in FIG. 7, the plunger 86 is supported in a depending cylindrical housing 90 of a radially reciprocable slide member 92 movable in a grooved radial slot 94 formed in the transfer disk. A plurality of equally spaced and radially arranged slide members 92 are supported in the disk in association with the arcuate grooves 70 and, as herein shown, the arcuate grooves 70 formed in the transfer disk are continued into their respective slide members 92 so that the ends of the grooves 70 delining the pockets 74 are disposed in the slide members. The number of pockets in the transfer disk, herein shown as eight pockets, is equal to the number of closure applying chucks 12 and, in operation, provision is made for elevating the plungers 86 to present their closures into their respective chucks 12 and for moving the slide members 92 inwardly to follow the circular path of movement of the chucks for a short distance and for rotating the transfer disk at variable speeds to conform to the speed of the chucks during the inward movement of the slide members so as to maintain the pockets in alignment with their respective chucks for a sufficient length of time to permit elevation of the closures and gripping of the same by their chucks.
As shown in FIG. 2, the transfer disk 22 is supported between upper and lower vertical shafts 96, 98. The upper shaft 96 which comprises the drive shaft is provided with a flange 97 at its lower end bearing against the upper surface of the disk. The lower shaft 98 is supported in a thrust bearing formed in the frame of the device and is also provided with a flange 100 bearing against the underside of the disk. The disk is connected to the shafts by bolts 102 passing through the flanges and the disk.
Each reciprocable slide member 92 is normally maintained in its outwardly extended position with the different portions of the arcuate grooves 70 in alignment by a spring 104 coiled about a stud 106 secured to and radially extended from the hub of the transfer disk. One end of the spring 104 bears against a shoulder 108 of the stud and the other end of the spring bears against a depending portion 110 of the slide member 92. The stud 106 passes through the depending portion 110 and the threaded outer end of the stud is provided with check nuts 112 for adjusting and limiting the outward movement of the slide member.
In order to provide suction to the opening 84 in the vertically movable plungers 86, each plunger is provided with a vertical passageway 114 connected by an adapter 116 to an individual flexible hose 118 leading to a manifold formed above the flange 97 of the upper shaft 96. Each flexible hose 118 passes through an opening 119 in the disk, as shown, and the manifold 120 is provided with passageways 121 in communication with a central passageway 122 in the shaft. The upper end of the passageway communicates with a rotary joint 124 which is cormected to a source of suction by a pipe 126.
The adapter 116 connected to each plunger 86 extends radially through a vertical slot 128 in the side wall of the depending cylindrical housing to provide clearance therefor during elevation of the plunger.
In order to elevate the plunger 86 to present its closure into a chuck 12, each plunger is further provided with a roller 13% mounted on a stud 132 secured to and radially extended from the opposite side of the plunger, a second vertical slot 134 being provided in the cylindrical housing 90 to provide clearance for the stud. The roller is arranged to ride in a cam path in a stationary earn 136 supported from the machine frame and which follows a path parallel to or concentric with the path of movement of the slide member 92 where it is moved inwardly through an are indicated at 138 defining a portion of the circular path of the closure applying chucks 12 which overlaps the transfer disk.
As illustrated in FIG. 8, the depending housing 90 of each slide member 92 is provided with a roller 140 which cooperates with a stationary cam 142 supported from the machine frame and which operates to urge successive slide members 92 inwardly against the tension of the spring 104 to cause the pockets 74 to follow along the are 138 defining the path of the chucks 12.
The chucks 12 are rotated at a constant speed, and in order to cause the pockets 74 to maintain the same speed and to remain in vertical alignment with their respective chucks as they pass through the are 138, provision is made for driving the transfer disk from the closure applying rnachine through a modified Geneva mechanism indicated generally at 144. The radius of the center line of the pockets 74 in their extended positions in the transfer disk is equal to the radius of the overlapping circular path of the closure applying chucks. The driven member 146 of the Geneva is provided with eight slots 148, and
the rotary closure applying machine is provided with eight driving rolls 150. The driving rolls 150 are supported in brackets 151 extending from a rotating portion of the closure applying machine, and the rolls 150 are arranged in vertical alignment with their respective closure applying chucks 12. In operation, when a pocket 74 of the transfer disk is moved inwardly from its normal circular path to follow the overlapping are 138 of the chucks 12, the transfer disk is momentarily increased and decreased in angular velocity to maintain the pockets in vertical alignment with their respective chucks during elevation of the closures thereto. As herein shown, when the reciprocable slide member 92 is moved to present a pocket 74 to a first point of intersection 153 of the are 138 with the normal circular path of the pockets, the
cam 142. effects inward movement of the slide member and, simultaneously therewith, the plunger 86 is elevated by the cam 136 to present its closure to its chuck 12, and the speed of the transfer disk is gradually increased during its travel through the first half of the are 138. Thereafter, during movement of the transfer disk through the second half of the are 138, the slide member 92 is moved outwardly; the plunger 86 is lowered; and the speed of the transfer disk is gradually reduced until the pocket 74 is moved to the second point of intersection 155 of the are 138 with the normal circular path of the pockets. Thus, in operation, the transfer disk is continuously rotated at an increasing and decreasing rate to maintain alignment of successive pockets 74 with their respective chucks 12. In practice, the plunger 86 is arranged to be elevated to dispose the bottom of the closure in a plane above the upper surface of the top plate 78 at which time the closure is gripped by the chuck and the plunger is lowered.
As illustrated in FIG. 2, the drive mechanism 144 from the closure applying machine 10 to the transfer disk shaft 96 includes a slip clutch indicated generally at 152 which is arranged to permit the shaft and the transfer disk to come to rest in the event of an overload or a jam. The driven member 146 of the modified Geneva is connected to a sleeve 154 supported for rotation in a support hearing 157 extending from a stationary portion of the closure applying machine. The sleeve 154 is connected to the driving element 156 of the slip clutch. The driven element 162 is connected to an elonagted sleeve 164, and an annular disk 166 engaging the driven element 162 is urged against the driving element 156 by a spring 168 coiled about the sleeve 164 and interposed between a ball thrust bearing 170 engaging the disk 166 and a spring flange 172 adjustably secured to the sleeve 164. The lower end of the sleeve 164 is provided with a flange 174 which carries a slotted cylindrical member 176 providing a keyway arranged to fit over an elongated key projection 178 out in the shaft 96. Under normal operating conditions the frictional engagement of the spring pressed elements is sufficient to rotate the shaft and the transfer disk, and in the event that a jam occurs such as to stop rotation of the transfer disk, the clutch will slip thereby protecting the parts from damage.
In practice, when it is desired to remove the transfer disk used for one size of closure and to replace the disk with one used for another size of closure, the upper shaft 96 may be unbolted at its flanged end 97 from the transfer disk and axially elevated through the elongated sleeve 164 to facilitate interchange of the disks.
From the description thus far it will be seen that the relatively lightweight elongated closures 20 can be successfully handled by a transfer disk 22 arranged to receive successive closures delivered thereto from the orienting mechanism 34 into successive pockets 74 at one station of the continuously moving disk and to elevate the closures from the pockets into the grip of successive closure applying chucks of a closure applying machine at another station, novel provision being made for driving the disk relative to the chucks and for moving the pockets in the disk so as to maintain alignment of the pockets and the chucks for a sufficient length of time to permit the closures to be elevated and gripped by the chucks. It will be understood that the plungers 86 remain in their elevated position for a sufiicient length of time to permit the chucks to effect gripping of the closures before the plunger is again lowered. In practice, the vacuum may be continuously applied to the suction opening 84 and may be of a value such that the closure may be easily separated from the suction when the plunger is lowered away from the closure gripped by the chuck.
Referring now to FIGS. 9 and 10, in a modified form of the invention, provision is made for handling conventional closures 180 by means of a modified transfer disk 182. In the modified form of the invention, the conventional closures 180 are supplied to the transfer disk by gravity through an inclined chute 184 arranged to convey the closures from the orienting mechanism in a line, the lower end of the chute 184 being curved to present the endmost closure in an upright position against the periphery of the transfer disk in a substantially horizontal plane. The chute 184 is supported on a downwardly inclined rail 181 attached to the machine frame. The periphery of the transfer disk 182 is provided with a plurality of circumferentially spaced inwardly curved cutouts or recesses 186 terminating in a hooklike pocket 188 which serves to strip the closure from the end of the chute and to carry it into operative position to be presented into the grip of the closure applying chuck 12. In practice, the succeeding closure is retained in the chute by engagement with the periphery of the disk beyond the instant pocket until a succeeding curved recess 186 is presented to the end of the chute to remove the succeeding endmost closure in a similar manner.
Each curved recess 186 cut in the periphery of the disk 182 has a horizontal bottom wall 190 arranged at a slightly lower plane than the bottom wall 192 of the chute so as to provide sutficient clearance to permit entrance of the closure into the recess, and when it arrives in the pocket 188, the closure is positioned over a vertically movable plunger 194 having a button 196 at its upper end. The plunger is disposed at a lower plane than the bottom wall 192 so that when the closure is deposited in its pocket, it will drop down over the button as shown. The plunger 194 is supported in a depending housing 198 formed integrally with radially reciprocable slide members 200, a plurality of which are provided similar to those previously described, and the plunger is also provided with a central suction opening 202 connected to a source of suction in the manner previously described. Thus, in operation, the closure stripped from the end of the chute by the hooklike pocket 188 is retained in the pocket by the suction.
In the event that the endmost closure does not flow readily into its curved recess 186 during the continuous rotation of the transfer disk, the discharge end of the chute is provided with a yieldable side guide 204 which is arranged to rock outwardly when engaged by a partially discharged closure to release the same and thus prevent a jam. As herein shown, the side guide 204 is connected to an arm 206 pivotally mounted on a stud 208 depending from the underside of the supporting rail 181. The guide is held in its normal position by a spring 210 connected to the supporting rail, and a stop screw 212 carried by the guide 204 is arranged to engage the supporting rail to adjustably limit the inward movement of the guide. A top guide 213 supported by the chute is provided to prevent upward displacement of the closures, and a curved top plate 215 secured to and extended from the guide 213 follows the contour of the disk above the recesses 186 for a short distance to prevent upward displacement of the closures in the recesses during the stripping operation and until the suction is effective to hold the closure in its pocket.
In some instances, such as when rotation of the transfer disk is stopped and comes to rest in a position where the discharge end of the chute 184 is aligned with a portion of the curved recess 186 it is possible that the endmost closure may flow out of the chute and be forced along the recess to be prematurely seated in the pocket 188, thus permitting a succeeding closure to partially extend into the recess. While such second closure will be released by virtue of the yieldable guide 204 upon subsequent rotation of the transfer disk, auxiliary means is provided to prevent such occurrence. This is accomplished by the provision of a stop arm 214, the end surface 215 of which comprises an extension of a guide rail 220 against which the endmost closure may rest and which forms a bar to prevent movement of the closure along the recess until the rotation of the disk is again initiated. As a result, the second closure held in the chute by engagement with the first closure is prevented from entering any part of the instant recess but will be free to enter a succeeding recess upon rotation of the disk. As herein shown, the stop arm 214 is pivotally mounted at 216 in an extension 218 from the guide rail 220 and is urged into the path of the endmost closure in the recess by a spring 222 as limited by a stop surface 224 on the extension 218.
The conventional closures 180 carried by the pockets 188 are thereafter moved into vertical alignment with their respective closure applying chucks and elevated into the chucks in a manner similar to the corresponding mechanism described in connection with the small closures wherein the slide members 200 are moved inwardly through the arc 138 corresponding to the circular path of movement of the chucks, and wherein the transfer disk 182 is rotated at variable speeds during movement of the pockets through the arc to cause the pockets to travel at the same speed and in vertical alignment with the chucks during their travel through the are 138 to the end that ample time is afforded to elevate a closure into position to be gripped by its chuck. A similar stationary cam is provided for cooperation with a cam roll 228 carried by the plunger 194 to elevate the same, and a similar stationary cam for cooperation with a roller 232 carried by the housing 198 is provided for guiding the slide member to present its pocket 1881 along the arc 138. As previously described, the plunger is elevated when it enters the are 138 and is again lowered before it leaves the arc. In practice, the plunger remains in its elevated position for an adequate length of time to permit the chuck to effect gripping of the closure before the plunger is again lowered.
From the above description it will be seen that the present rotary transfer disk may be adapted to handle conventional closures delivered from the orienting mechanism, as well as the small elongated closures, in a rapid and eflicient manner to transfer the closures into operative position to be received and gripped by successive closure applying chucks for application to their respective containers.
