This invention relates to e paper cup counting and nesting attachment for use in connection with apaper cup forming machine of a type illustrated and described in in pending application for patent for a at .paper cup forming machine, filed .March 15, 1924, Serial No. 699,424. The present invention relates to an attachment connected with the machine and operable thereby to automatically mark off formed cups at predetermined intervals after which the formed cups are advanced, expanded and nested one within the other as they are pushed over'a discharge table.
It is an object of this invention to provide a cup forming machine with attachments adapted to mark off cups in predetermined quantities and nest the formed cups as they are advanced in a discharge chute from which the nested cups may be taken in. counted numbers discernible by markings occurring at intervals on the nested cups.
It is also an object of the invention 'to provide a cup forming machine with a mechanism operable from the machine and having means whereby a marking device is caused to be operated at selected intervals to mark cups at predetermined intervals so that a counted number of the cups may be readily separated from a stack of nested cups for insertion into a carton.
It is a further object of the invention to provide a paper cup forming machine with an attachment adapted to automatically expand flat cups so that the cups may be nested one within the other as they are moved into a discharge chute.
It is an important object of this invention to provide a cup forming machine wherein a cup blank feed carriage is provided with means for causing actuation of a marking device at predetermined times to place indents on selected cups whereby the cups when nested in stacked relation may be readily taken from the machine in counted quantities for packing in cartons.
It is another important object of this invention to provide a stack of normall flat cups in such interfitting or nested re ation that the cups readily open into osition for use when individually remove from the stack.
Other and further important objects of this invention Wlll be apparent from the disclosures in the accompanying drawings and specification.

As shown on the drawings:
The reference'numeral 1 indicates a machine frame having journalled thereon in suitable bearings a main driving shaft 2 adapted to be driven from any suitable source of power. the shaft 2 and is trained around a sprocket gear to drive a clutch mechanism designated as a whole by the reference numeral A chain 3 is driven from.
4. The clutch 4 is adapted to be controlled by means of a handle 5 which when operated actuates a starting shaft 6 whereby a yoke carrying pins 7 acts to shift a clutch collar 8. The clutch mechanism 4 may also be operated by means of a handwheel 9. Mounted on one end of the machine frame is a cup blank feed magazine 10 having blank feed mechanisms adapted to be operated from the clutch carrying shaft 11. A gear 12 and a bevel gear 13 are operated from the blank feed mechanisms through a gear 14. The gears 12 and 13 are mounted on a shaft 15 on the front end of which a wheel or disk 16 is mounted. An eccentric pin 17 is mounted on the wheel 16 and has connected therewith one end of an eccentric rod or bar 18. The eccentric bar 18 is pivotally supported near its other end on a pin 19 carried on the lower end of a link 20 which is fixed on a pin 21 carried by a slidable block 22. The block 22 is slidable in a slot 23 provided on the front of the machine frame 1. An extension arm 24 is integrally formed at an angle on one end of the bar 18. Pivotally connected to the end of the arm 24 is one end of a connecting rod 25 the other end being pivotally connected to the upper end of the outer arm of a double arm lever 26. The lower end of the lever 26 is pivoted on a bracket 27 secured on the machine frame 1.
A bar 28 is connected with the slidable block 22 and has mounted thereon a blank advan ing plate 29 which extends into the path of the advancing cup blanks. A blank gripper mechanism 30 is also carried by the bar 28. A cup blank carrying carriage 31 is provided on the bar 28 and has a cup blank centering flange formed thereon.
When a cup blank is fed out of the cup blank holding magazine 10 it is delivered onto a stationary table 32 provided with a raised curved stop edge 33. A stationary table 34 is provided and is separated from the table 32 by a diagonal o ening or slot 35 in which a pair of separate upper and lower blank folding bars 36 are adapted to operate.
A cup blank 37 is adapted to be gripped by the gripper mechanism 30 and is carried over the table 3234 into a position over the folding bars 36. A glue applying mechanism 38 is operable from a cam shaft 39 which has a beveled gear 40 thereon meshing with the bevel gear 13 to receive a drive therefrom. The glue applying mechanism is adapted to apply a dab of glue to the under surface of the advanced cup blank 37.
When the gripper mechanism 30 is advanced into position to grip the next cup blank the blank feed plate 29 is in its advance position over-the stationary table 32 and above a portion of the advanced cup blank 37. Just previous to the time that the gripper mechanism starts to move away from the cup blank magazine the blank folding bars 36 are operated by a cam wheel 41 which is driven by the cam shaft 39. The folding bars 36 are thus raised through the table opening 35 and act to bend up a portion of the advanced cup blank 37 while the other portion of the cup blank is held in place by the feed plate 29.
As the gripper mechanism engages the next blank and starts to move away from the blank holding magazine 10 the blank feed plate 29 moves through the slot between the bars 36 thereby causing the upturned portion of the first cup blank to be folded over against the. top surface of the feed plate 29. v
As the partially folded cup blank is advanced by the feed plate 29 a second glue applying mechanism 42 operable by the cam wheel 41 acts to apply a strip of glue to a margin of the blank. As the strip of glue is being applied to a margin or flap of the cup blank, the cup blank is advanced into the field of operation of a flap-folding mechanism operable from a cam 43 on the cam shaft 39. The glued flap is thus folded over against the body of the partially formed cup. A cup feed cam 44 operable by a gear train 45 (Figure 1) now acts to advance the partially formed cup as the feed plate 29 starts to move back toward the blank holding magazine 10.
A. cup tip bending device 46 is operable by a cam 47 which receives a drive through meshing bevel gears 48 and 49. The beveled gear 49 is mounted on the end of the cam shaft 39. The cup tip bending device 46 acts to bend over the tip of the cup and at the same time the feed cam 44 engages the cup and advances the same thereby causing the cup tip to be bent upwardly against the underside of the body of the cup so that the spot of glue applied by the glue mechanism 38 acts to glue the tip to the cup body thereby completingthe forming of the flat cup 50."
The cup 50 is advanced by the feed cam 44 between a pair of feed rollers 51 which press the glued parts together and at the same time advance the cup 50 over onto a table extension 52. Secured on the end of the machine frame 1 is a casting 53 having an extending arm 54 on which a carriage 55 is slidably engaged. A stop 56 is fixed on the end of the arm 54. The carriage 55 is provided with vertical guide slots in which a plate 57 is slidably engaged. Theslideplateis connected bv tog les to the lever 26 (Figure 2). Integrally formed at right angles to the upper edge of the slide plate 57 is a horizontal plate 58 which extends transversely beneath the table extension 52. Secured to the bracket plate 58 on apposite sides of the table extension 52 area pair of slide bars 59 recessed at 60 leaving upturned hooks or fin ers 61. The hooks 61 are slightly curve to conform to the curvature of the curved oppn end of the flat cup 50. A cup pocket is t us provided in the slidable cup removing bars 59 which slide in guide grooves or slots 62 provided in the bottom of a flanged or channel-shaped cup discharge chute or' trough 63. The cup discharge chute 63 is supported by a bracket 64 secured to the discharge end of the machine frame 1.
Mounted on the machine frame casting 53 between the 'feed rollers 51 and the discharge chute 63 is a grooved or angle crosssectioned cup uide rail 65 and a supporting rail 66. Rigi 1y secured to the top of the outer portion of the guide rail.65 is a cup expanding rail 67 having an inwardly projecting ta ered or beveled flange 68. Fastened to t e top of the rail 66 is a cup expanding rail 69 having an inwardly directed tapered or beveled flange 70 disposed opposite the flange 68. The flat cups advanced by the feed rollers 51 are delivered one at a time between the beveled flanges 68 and 70 of the cup expanding rails 67 and 69 respectively and are gradually expanded at the open ends so that the cups may be nested one within the other (as illustrated in Fig ure 3) as the cups are pushed into the cup discharge or outlet chute .63.
A cup counting and marking mechanism is provided on the machine and comprises a bracket 71 which is secured to the \machine frame 1- and is provided with a bearin 72 in which a shaft 73 is journalled. upported .on one end of the shaft 73 is a hookshaped lever 74 havin a head 75 on the free end thereof. A coi ed spring 76 has one end thereof secured to the lever 74 and the other end attached toa pinion or arm 77 forming on the bracket 71. Supported 'on the opposite end of the shaft 73 is a ratchet 78 carrying a pin 79. A spring controlled pawl 80 is supported on .the lever 74 and co-acts with the ratchet 78. The ratchet pin 79 is adapted to co-act at predetermined times with a finger 81 integrally formed on one end of a bar 82 fulcrumed on the bracket arm 77.. A resilient hook 83 is attached to the opposite end of the fulcrumed bar 82. The pawl 80 and ratchet 78 are actuated b the lever 74 which in turn is operated eac time the block 22 is advanced toward the cup blank magazine to permit the grippers 30 to grip. another cup blank. Supported on the slidable block 22 is a bracket 84 having a rod 85 adjustably mounted thereon and positioned to move in a path in line with the head 75 of the lever 74 to actuate said lever and the ratchet 78 each time the block 22 is advanced toward the cup blank holding magazine 10. The pin 79 on the ratchet 78 is thus gradually advanced toward the finger said hook is positioned in the path of a pin .88 mounted on a disk 89. The disk 89 is sup orted on one end of a spring controlled sha t 90 which is journalled in a bearing bracket 91 mounted upon the traveling carriage 31. Projecting diametrically through anopening in the enlarged, opposite end of the shaft 90 is an arm. 92 held in place by a set screw 93. A marking pin or pointer 94 is carried by the arm 92 and is adapted to r produce a mark or indent 95 (Figure 3) on cups at counted intervals so that when the expanded cups are stacked in nested relation in the dlscharge chute63 they may be removed in counted numbers ready to be packed in cartons for shipment or storage.
The operation is as follows:
A stack of cup blanks 37 of a shape sim-. ilar to that illustrated in Figure 9, is deposited in tne cup blank magazine 10. By operating the control handle 5 the clutch mechanism 4 is operated and a drive is transmitted by the chain 3 to the shaft 11 and to the blank feed mechanisms. The blank feed mechanism is so constructed that at a predetermined time in each revolution the owermost cup blank in the magazine is fed out of the magazine onto the raised portion 33 of the stationary table 32.
With the delivery of a cup blank from the magazine the disk 16 actuates the eccentric bar 18 and the link 20. The lower gripper jaw of the gripper mechanism 30 is thus moved into open position. The slidable block 22 is advanced by the action of the eccentric bar 18 so that the open gripper mechanism is moved into position ready to grip the advanced cup blank. With the continued rotation of the disk 16 the gripper mechanism is closed to grip the advanced cup blank; atter which the block 22 starts tomove away from the magazine 10. The cup blank is pulled over the table sections 32 and 34 and over the lowered bars 36.
The gripper mechanism 30 is now opened to release the advanced cup blank as the block 22 again starts to move toward the magazine 10. The feeder plate 29 is moved over the top of the cup blank as the flange on the carriage 31 acts to push the cup blank back against the raised edge 33 of the table 32 to properly center the cup blank. The glue applying mechanism 38 is now operated from the cam shaft 39 and acts to apply a dab of glue to the under surface of the centered cup blank.
The cam wheel 41 now acts to raise the bars 36 to bend up a portion of the cup blank along one edge of the feed plate 29. As another blank is gripped by the gripper mechanism the block 22 startsto move away from the magazine and the feed plate 29 acts to draw the cup blank between the raised bars 36 to bend over the upturned portion of the cup blank. As the cup blank is folded and advanced the second glue applying mechanism 42 is operated by the cam wheel 41 to cause a strip of glue to be applied to a margin of the cup blank.
With the continued advance of the feed plate 29 the glued margin of the cup blank 1s next creased, and bent upwardly after which the cam 43 on the cam shaft 39 acts to operate a flap folding mechanism whereby the glued margin of the cup blank is bent over against the body of the cup. The
artially formed cup is advanced further by the feed plate 29 into a position wherein the tip of the partially completed cup projects over an edge of the table section 3 1. The cam 47 now acts to operate the cup tip bending device 46 which bends the tip of the on downwardly. At this stage in the operation the block 22 starts to again move toward the magazine 10 and carries the rod 85 into contact with the head 75 of the lever 74 thereby swinging the lever upwardly and causing the pawl 80 to rotate the ratchet 78 the distance of one tooth (Figure 10) each time another cup blank is engaged by the gripper mechanism. The pin 79 on the ratchet 7 8 is thus gradually carried around into the position illustrated in Figure 13 whereit contacts the finger 81 of the fulcrumed bar 82. The bar 82 is thus actuated and moves the book 83 upwardly from the position shown in Figure 12 into the position illustrated in Figure 13. As the block 22 starts to move away from the magazine 10 the carriage 31 carrying the marking mechanism brings the pin 88 on the disk 89 into contact with the raised hook 83. The disk 89 is thus rotated thereby causing a partial rotation of the shaft 90. The arm 92 is thereby swung downwardly causing the pointer 94 to make an indent 95 in the par tially formed cup 50 when in the position illustrated in Fi ure 1. The pointer 94 is actuated to mar every-twenty-fifth cup. As the pin 79 passes the finger 81 the bar 82 swings back to normal position thereby lowering the hook 83 out of the field of movement of the pin 88.
With the bending down of the tip of the cup 50 the block 22 and the carriage 31 move toward the magazine 10 and the cup feed plate 29 is moved out of the partially ormed cup. I The cup feed cam 44 now engages the flat cup and feeds the same between the feeding rolls 51. As the cup is advanced by the feed cam 44 the bent over tip of the cup is bent upwardly against the body of the cup so that the dab of glue will 'tainers.
- struction may cause the tip'to adhere to the body of the fiat cup.
The cup feed rolls 51 now act to advance the completed marked flat cup over onto the table extension 52. The flat cup drops by gravity into the pocket of the cup removing bars 59. The bars 59 are advanced by the carriage 55 which is slidable on the guide bar 54 by the action of the lever arm 26 and the toggle mechanism connecting said lever arm with the plate 57 The lever arm 26 is actuated by the rod 25 from the end of the arm 24 forming a part of the eccentric bar 18. As the carriage 55 starts to move outwardly the bell crank 96 is operated by the link 97, (Figure 2) so that the plate 57 is raised and elevates the bars 59. These bars 59 being positioned beneath the cup lift the same and carry the cup outwardly between the cup expanding flanges 68 and with the tapered end of the fiat cup in the lead. As the wide 1part of the cup comes into contact with the anges 68 and 70 the open end of the cup is expanded or opened as illustrated in Figure 7.
The flat cups are automatically formed by the machine and are advanced by the rollers 51, one at a time to be engaged by the bars 59 which lift the cups so that the hooks 61 are positioned to pull the cups between the flanges 68 and 70 to expand or Open the cups as they are being advanced and nested one within the other before entering the cup discharge chute 63. Every twenty-fifth cup is marked with an indent 95 (Figure 3) so that the nested cups may be readily removed from the chute 63 in counted numbers and deposited in cartons ready for storage or shipment.
The counting mechanism may be arranged to mark and count off any desired number of cups by simply changing the ratchet 7 8 to one with more or less teeth as desired.
The cups are automatically glued, formed, marked, expanded and then nested one within the other and discharged in nested counted form into the discharge chute 63 ready to be packed in cartons or other con- I am aware that numerous details of conbe varied through a wide range without departing from the principles of this invention, and Itherefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.
