RECEPTACLE IEOBMINGI' Application led December This invention relates to improvements in machines particularly designed for formin from prepared blanks or sheets of materia open receptacles or cartons and filling or packing such receptacles with articles. The invention more particularly relates to such machines designed for use in candy factories to produce the receptacles, and to pack a predetermined number of pieces or units of candy therein, such candy usually being wrapped in thin sheets of paper before being delivered to the machine.

vIn the manufacture of certain kinds of candy it has been found desirable, to facilitate handling in' storage, and for display in vending, to pack the candy in small paper receptacles or cartons, a predetermined number of pieces or units being usually pazked in each receptacle. The candy to be thus packed is cut in small pieces, preferably rectangular v,in form, each piece being usually wrapped in a thin sheet of paper to render it sanitary. The cutting and wrapping of the material or candy, as above described, is usually accomplished by automatic machinery and forms no part of the present invention.

By present methods7 after the candy has thus been wrapped or prepared for packing, it is distributed upon one or more packing tables where". it is manually packed into open receptacles, usually by girls employed for that particular purpose. The receptacles are delivered to the packers in the form of blanks which must be manually folded and formed before the candy or other articles can be placed therein. This method of packing candy repuires considerable time and labor, resulting in an increase in the cost of manufacturing. It is, therefore, desirable that means be provided whereby the receptacles may be mechanically folded and formed and the candy packed therein, thereby dispensing with the manual labor heretofore required in preparing the candy or articles for final distribution, with a resultvant decrease in the cost of production.

By the employment of the novel receptacle forming and filling machine of our in-' vention the blanks are mechanically and automatically folded and the receptacles filled or packed with a predetermined number of candy units.' The cand filled receptacles are then successively devivered onto or MINNEAPOLIS, MINNESOTA, NEAroLIs, MINNESOTA, A con- AND FILLING MACHINE.

may readily be removed and placed in shipping boxes to facilitate handling in storage and transit.

Broadly, the'machine comprises a holder' in which a plurality of receptacle blanks are stacked, and from which the blanks are successively fed to forming and intermittentl moving chain dies. As the receptacle blank travels through the machine the various operations of folding the sides and ends thereof to form a receptacle are progressively performed, and as the completed receptacle nears the discharge end of the machine it is automatically filled or packed with a plurality of candy pieces or units, and finally discharged onto a traveling belt or conveyor, as hereinbefore stated.

The object of this invention, therefore is to (provide an improved receptacle-forming an filling machine of simple and practical construction, which will be positive and efficient in performance.

Other objects of the invention will appear from the following description taken in connection with the accompanying drawings.

In the drawings We disclose a structure designed to carry out the various objects of the invention, but it is to be understood that the invention is not confined to the exact features shown, as various changes may be made Within the scope of the claims which follow.

Machine frame.

The frame of this novel receptacle-fium-A ing and filling machine is preferably constructed of cast metal, and comprises a top plate.30, and the front and rear walls 31 and 32, res ctively, as shown in Figures 1 and 3. he two ends of the frame and also the bottom are preferably opehl, as

shown, so that access may be had to the driving mechanism mounted therein. Suitable legs 33 may also be provided for supporting the frame, or, if desired, these legs may be eliminated and the frame securedto a table or other supporting means.

Receptacle blank feeding mechanism.

The means provided for holding and feeding the blanks from which the receptacles or cartons are formed, preferably consists of a holder or rack secured to the upper surface of the top plate 30 of the frame adjacent one end thereof, as shown in 'Figures 2 and 3. As shown in Figures 2l and 22, this holder or rack comprises a pair of rails 3l having wall members 35 secured to the upper portions thereof and to which a plurality of upright guides 36 are secured by such means as the screws or bolts 37. The rails 34 are supported upon the frame tpp 30 by means of shouldered studs 38 as s iown.

The form of blank used to make the typeof receptacle shown in the drawings is represented in Figure 23. As here shown the main' body of the blank is preferably rectangular in form and each end is provided With an outwardly extending central end-portion 39. A slit or cut 41 is preferably provided on each side of the central end-portions 39 and these slits extend into the body of the blank a distance substantially equal to the height of the walls of the receptacle when finished. The blanks may also be scored as indicated by the dotted lines in Figure 23 so that the material may more readily be bent in the formation of the receptacle, as will hereinafter be described. In the actual operation of the machine, however, it has been found unnecessary to score the blanks to facilitate bend- 4ing, it being necessary only to provide the slits 4,1 as shown.

Before starting the machine, the blank holder is filled with blanks as shown in Figures 2, 3 and 21. When the blanks are thus placed in the holder, it will be seen, by reference to Figure 2 that the central endportions 39 of the blanks will be fitted between the opposed edges of the upright guides 36 and lwill outwardly project therebeyond. When thus positioned, the ends or corners of the main body of the blank will also be fitted between the sides of the guides 36 thereby preventing the blanks from longitudinal or transverse movement, but allowing them to downwardly travel, as indicated by the arrow in Figure 3, to the feed slide as they are successively fed from the bottom of the stack to the receptacle-forming-plungers and dies. The feed slide preferably consists of a block 42 having oppositcly extending tongues 43 provided thereon which are adapted to slide in grooved guides 44 formed in the inner faces of the two opposed rails 34, as particuthe length of these pins, the gap between the ends thereof and the faces 48 may be adlai-ly shown in Figure 22. The u per portion of the feed block 42 is provide with an inclined face 45 terminating in a shoulder 46 adjacent the central upper portion thereof. The lower corner 47 of the inclined face 45 preferably extends slightly below the recessed faces 48 of the rails 34, which faces form the lower support for the blanks when the feed slide 42 is in its inoperative posi tion, as shown in full .lines in Figure 3 and dotted lines in Figure 21 (lefthandside of the ligure).

The two upright guides 36, adjacent the discharge end of the blank holder, referably terminate short of the recesse faces 48 of the rails 34 so as to provide a gap 49 between the lower ends thereof and the faces 48 through which the blanks may be. fed, one at a time, to the forming dies. The gap 49 must necessarily be slightly wider than the thickness of the material from which the blanks are made in order that but one blank may be fed therethrough at" a time. In order that this gap may be varied or adjusted to suit the thickness of the blanks, pins 51 are preferably provided in the lower faces of lthe two upright guides 36 adjacent the discharge end of the blank holder as shown in Figure 22. By varying justed to allow f but one blank to be fed therebetween, and over the formino dies at each forward movement of the feed slide or block 42. If the pins 51 are eliminated, the lower ends of the guides 36 must be so adjusted and spaced from the `faces 48 as to allow but one blank to pass therebetween. If desired means may be provided for adjusting the width of the gap 49 to the thickness of the blank material. Such an adjust nient may be provided by vertically moving the guides 36 in the wall members 35 of the blank holders. The lower ends of the upright guides 36 at the opposite end of the blank holder are referably seated upon the faces 48 of the rails 34 so as to prevent any one of the blanks from being backwardly drawn with the fCed block 42 on itsreturn stroke. The rails 34 are preferably provided with forwardly'extending end-portions 52,L as shown in Figure 21, to furnish a support for the blanks when fed over the forming dies, as indicated'by the dotted lines in the saine figure. .j l j v i The means provided for reci rocallyactuating feed block. 42 .preferab y consists in the `provision of an oscillating arm 53, pivotally mounted in a forked `bracket 54 sesecured to the rear wall 32 ofk the frame. (Figures 2 and 3). 1 A connecting A"rod 55 connects the upper end of the oscillating arm" 53 with the feed block 42 so that oscillation of the arm will impart a reciprocal movement to the feed block 42. The connecting rod 55 is preferably provided with means for adjusting its lene'th, as indicated at 56, so as'to properly position the feed block 42 with relation to the blanks. 57 has one end connected, by means of a pin 58;' to the lower end of the arm 53 and the other end of the connecting rod is mounted upon a crank pin 59 carried by a crank arm 61 secured to one end of a short shaft 62 which is mounted in a bracket 63 secured to a suitable cross member 64 of the machine frame, clearly shown in Figure 1. A bevel A connecting rod pinion 65 is secured to the other end of the shaft v62 and meshes with a similar pinion 66( mounted upon a shaft 67 rotatably mounted in suitable bearings 68 provided in the front and rear walls of the machine frame. (See Figure 3), The shaft 67 is driven from the main drive shaft 69 by means of a pair of gears 71 and 72, as shown in Figures 1 and The drive shaft 69 is mounted in'similar bearings 73 provided in the frame as shown in Figure 24.

In the operation of the feed block 42, the lower corner 47 of the inclined face 45 of the slide will project beneath the stack of blanks, when the feed block 42 is in normal "'or resting position, as shown in full lines in Figure 3 and dotted 'lines in Figure 21. When thus positioned, one end of the stack of blanks will be resting upon the inclined face 45 of the feed block thereby slightly lifting or raising the lower blank out of contact with the blank supporting faces 48.

It will also be noted, by reference to Figure 3, that the shoulder 46, the height of which is slightly less than the thickness of the blank material, will be out of contact with the lowermost blank. As soon, however, as the feed block starts its forward movement, the shoulder 46 will engage the adjacent central end-portion 39 of the blank and will thereby forwardly move it, as indicated in Figure 2l. When thus being fed forwardly by the feed block, the opposite end of the blank will passbeneath the pins-51, and the blank will thus slide along upon the blank supporting faces 48 to the dotted line position shown in Figure 21, and will remain in such position while the feed block 'returns -to its normal or starting position. As a result of the use of the inclined face 45 of the feed block, the stack of blanks will be compressed at one end thereof before the shoulder 46engages`the lowermost blank, while the opposite end of the stack will be relatively less compressed, thereby permitting the lower blank to be fed from beneath the stack with- -out danger of buckling or bending. If desired. means may also be provided Yfor limiting the forward movement of the blank to prevent it from moving too far when fed provided in the head 79.

over um die backs 74 and 78 by the feed block 42, thereby positively locating the blank over the die blocks.

Receptacle forming mechanism.

The means provided for folding the blanks to form the receptacles or cartons preferably consists in the provision of a forming die 74 mounted above the top plate 30 of the machine in spaced relation thereto. As shown in Figures 5, 6, 7, 8, 9 and 10, this die is provided with oppositely extending lugs 75, 75, and 76, 76, and it is preferably secured to the top of the machine by means of shouldered studs 77. As shown in thc drawings the die block 74 in reality constitutes but one side of the forming die as the other side thereof is constructed by means of a complementary die block 78, which is yieldably mounted in the head 79 of a T-shaped bracket 81, having one end secured to the top plate 30 of the machine by means of a shouldered stud 82, and the other end secured to a bracket 83 by a bolt 84. The bracket 81 is similarly arranged in spaced relation to the top plate 30. It will be noted by referring to Figure 5 that the bracket 83 is securely bolted to the top plate 30 by means of bolts 80.

As shown in Figure 8, the die block 78 is preferably yieldably secured to the head 79 by means of threaded studs 85 having one end secured thereto and the other end passing through sockets 86 and a ertures 87 ompression springs 88 are mounted in the sockets 86 and threaded nuts 89 are mounted on the threaded end portions of the studs 85 thereby providing means for adjusting the diev block 78 with relation to its complementary die 74. By thus yieldingly mounting the die block 78, the carton blank, when downwardly forced between the die blocks 74 and 78 by means of the reciprocally mounted plunger 91, will be firmly held in place as shown in Figure 8.

The forming plunger 91 is mounted in an upright bearing 92 provided in the horizontal portion 93 of the bracket 83, and has its upper end pivotally connected to an oscillating arm 94 by means of links 95. The oscillating arm 94 is mounted upon a rock shaft 96 supported in bearings 97 and 98 provided in the upper portion 99 of the bracket 83. A relatively short arn'i 101 is mounted on the opposite end' of the shaft 96 and has a connecting rod 102 pivotally connected thereto which downwardly extends therefrom through an opening 103 in the top plate 30 of the machine and has its lower end operatively connected to a driv` ingl mechanism which will hereinafter be described.

In the operation of the receptacle forming dies 74 and 78 and the plunger 91, the

blanks are fed from the blank holder to the dotted line position, indicated in Figure 21, and the ful line position indicated in Figures 1 and 7, in which position the blank will be inter osed between the die blocks 74 and 7 8, an the lower face of the plunger 91, and will be supported upon the end portions 52 of the rails 34. As the plunger 91 is moved downwardly, by the oscillating arm 94, the blank will be forced between the two die blocks, to the position shown in Figure 6. When the plunger 91 moves from the position shown in Figures 1, 3, 4 and 21, the blank will be lon itudinally bent or folded along the dotted mes a, a (Figure 23), thereby forming the opposed side walls of the receptacle, and thus completing the first operation in its formation. As soon as the side walls have thus been formed, and the lunger 91 reaches the position shown in igure 6, the downward movement of the plunger will be temporarily interrupteduntil the second forming operation has been completed. The second forming operation conslsts in inwardly bending the corners b of the side walls, along the dotted lines c to partially form the ends of the cartons. (Figure 23).

The means provided for inwardly bendin the corners, or ends b of one of the si e walls, to partially form the ends of the receptacle, preferably consists in a pair of rods 104, reciprocally mounted in bearings in the opposed lugs 75 and 76 of the die block 74. These rods are connected together at one end by a cross bar 105 as shown 1n Figures 2 and 5. This cross bar is engaged by a cam 106 upon the upper reduced end portion 107 of a vertical shaft 108, (Figure 1) mounted in a suitable bearing 109 provided in the top of the machine frame.

ompression springs 111 are coiled about the rods 104 and function to yieldably hold the bar 108 against the face of the cam 106,

collars 112 preferably being secured to the .rods 104 to engage one end of each spring while the opposite ends of the springs are adapted to bear against the lugs 75 of the die block 74, as shown in Figure 5. The rods 104 function to inwardly bend two of the corners or ends b of one of the side walls as hereinafter described.

A pair of L-shaped rods 113 are also mounted in the opposed lugs 75 and 76 of the die block 74, adjacent the outer ends thereof, as shown in Figure 5. These rods are similarly connected to ether at their outer ends by means of a yo e 114, which is adapted to engage a cam 115, also mounted on the upper reduced end-portion 107 of the upright shaft 108. Similarly, the yoke 114 is yieldably held in contact with the cam 115 by means of springs 111 and collars 112. The rods 113 are provided with inwardly projecting end portions 116, having curved ends 117 adapted to engage the ends b of the other side wall when the rods are actuated bythe rotation of the cam 115.

In the operation of the rods 104 and 113 'the upriht shaft 108, which is operatively connecte to the driving mechanism mounted beneath the machine top 30, will be rotated, causing the cams 106 and 115, mounted on the upper end thereof, to be rotated also with the resultant actuation of the rods 104 and 113. Referring to Figures 5 and 9, it will be noted that as the cam 106 is rotated, as indicated by the arrow in Figure 5, the rod 104 will be moved towards the partially completed receptacle positioned between the die blocks 74 and 78. Such movement of the rods will cause the ends. thereof to engage the corners b of one of the receptacle side walls with the result that the ends will be bent along the dotted lines c, shown Vin Figure 23, and around the ends of the plunger 91 as shown in Fi res 5 and 9. Before the rods 104 start their return movement ther rods 113 will commence to move forwardly so that the curved ends 117 thereof will engage the ends b of the other receptacle side wall and will bend them inwardl'y as shown in Figures 5 and 10.' As soon as the corners b, engaged by the curved ends 117 of the rods 113, reach substantially the osition shown in Figure 5, the rods 104 wil be retracted, thereby allowing the curved ends 117 to fold the opposite or outer corners ZJ over the inner corners, as clearly shown in Figure 10. As soon as the corners b have thus been folded or bent to overlap one another the plunger 91 will resume its downward movement and will thereby force the partially completed carton or receptacle downwardly from the position shown in Figures 5 and 6 into one of the pocket dies of a movable chain die (see Figure 11), which will next be described. When the receptacle is thus forced into the movable chain die the oppositely extending end-portions 39 of the blank will be upwardly bent along the dotted lines d (Figure 23) tothe position shown in full lines, Figure 11, and dotted lines, Figure`13.

M ovable chain dies.

Figures 27, 28, 29 and 30, show in detail the construction of the movable chainv die employed in conjunction with this novel machine to progressively and intermittently move the cartons or receptacles through the machine, as the various operations in the tion. Each chain is also preferably mounted so as to be in 'direct contact with the upper surface of the machine top 30, (Figure 29), so that the weight of the two chains will becarried directly by the top plate 30, and not by the sprockets. Also, by this arrangement the plate 30 will form the bottoms of the die pockets formed between the adjacent arallel sections of the two chains, as will su sequently be described.

Each belt or chain preferably comprises a plurality `of similar die-forming members or blocks 121, alternately arranged in the chains, and each such member having an outwardly extending blade 122 adapted to cooperate with the blades of adjacent blocks to form the side walls of the die pockets, as particularly shown in Figure 27. In this figure it will be noted that a series of lsuch die pockets are formed between the adjacent sections of the two chains, the blades 122 froming the side walls of the die pockets and the blocks 121 the ends thereof. As shown in Figures 28, 29 and 30 the central portion of each die-forming member or block 121 is preferably cut away to provide a channel or groove 123 adapted to receive the connecting means provided for pivotally connecting or linking together the blocks 121. The blocks 121 of the chains are connected together by means of spaced arallel links 124 and pins 125 Ipreferably having their ends headed over and seated in countersunk seats, as shown in Figure 29. Anti-friction rollers 126 are preferably interposed between the spaced connecting links 124 adapted to engage the opposed bars or rails 120 to prevent the` adjacent sections of the two chains from spreading when the receptacles are being formed in the die pockets provided therebetween by the blocks 121 and blades 122. The rails 120 may be secured to the top plate 30 of the machine by such means as the bolts l or screws 127. In Figure 27 there is shown in the movable chain die pockets, the relative positions of the receptacles, and the result of each forming operation as the receptacles progressively and intermittently advance through the machine in the formation thereof.

For intermittently actuating the movable chain dies we preferably provide an interv mittent driving mechanism commonly known in mechanics as a Geneva stop movement.

As shown in Figure 27 the drive sprockets l 118 are secured to the upper side of a air of upright shafts 128 rotatably mounte in suitable bearings provided in the top plate 30 of the machine frame (Figures 2, 5 and 24). The bearings 129 are here shown as formed integral with the top plate 30, but it is to be understood that, if desired, these bearings may be constructed independentli7 of the machine frame and secured thereto by suitable means. Spiral gears 131 are "ecured to the lower ends of the upright as shown in Figures 4, 25, 26 and acomplef isk 137 mountedon the drive shaft 69. A drive pin 138 is secured to the' mentary drive `disk .137 adapted to en age the ra'digl slots 136 to rotate the whee 135 when t 137 is rotated. (See Figure 25). A khub 1,39 is provided on one side of the disk 137 in alinement withthe. face of the slotted wheel 135. The hubjis adapted to engage correspondingl curved faces 141 rovided between the ra ial slots in the whee to lock said wheel against rotation when the drive pin 138 is out of engagementwith the slots 136 as shown in Figure 26. A portion of the hub 139 is cut away to provide a face 142 shown in Figures 25 and 26, to provide l clearance for the slotted wheel 135, when belco ing rotated by the pin 138 (Figure 25). U

In the operation of the intermittent drive mechanism above described, the slotted wheel 135 and therefore the shaft 133 will be rotated one-eighth of a revolution for each revolution ofthe drive shaft 69. When the wheel 135 is in locked position, it will be 'powheel. Asthe disk 137, and therefore the pin 138 and hub 139, continue to rotate, the pin will engage the next slot in the wheel, as indicated by the dotted lines in Figure 26, and will thus commence to rotate the wheel. It is to be uderstood, of course, that when the pin 138 engages the next slot 136, 'the clearance face 142 of the hub 139 will be moved to the dotted line position in Figure 26, in which position the wheel may be rotated by the pin as shown in Figure 25. In thedrawin we have shownthewheel 135 as having eltght driving slots, but it is to be understoodl iat the number ofslots maybe varied as desired, to increase orV decrease the intermittentv travel of the movable chain dies. v

Referring to Figure 27 it will be noted that the idler sprockets 119, su porting one end of each chain, are rotatably mounted upon studs 143 secured to the top plate 30 of the machine frame. If desired, these studs may beA adjustably mounted in the frame so as to rovide means for taking up slack in the chains, caused by wear, etc., and they may bealso so arranged as to be adjustable to and from each other to provide means for slightly varying the lengths .of

e disk the diepocket's, composed vofthe adiacentv 65 sections of the two chains.l

AAfter the partially completed carton or receptacle has been downwardly moved from p in Figure 1l, it will'advance to the osi-,

tion shown in Figure 12, where it wi be engaged by means for inwardly and down- -wardly folding or bending theI upstanding @central end-'portions 39 thereof' tofcomplete).

the forming operation of -thecartom 'f he means provided for inwardly and down wardly bendingl theend-portion 39 lof. the incompleted carton is clearly-l shown. in Figures 12` 13A and 14. As here shown such means preferably consists in the provision of a pair of pivotally mountedcurved fingers 144 upwardly projecting lthrough, elongated apertures 145 provided in the machine top 30, and adapted to have their ends swing.

over the incompleted carton as shown vin Figures 12 and 13. Each finger 144 has an integral hub 146 which is apertured to receive a stud 147 to provide a pivotal mounting therefor. The studs 147 are preferably secured to a block 148 secured to the underside of the machine top 30, by suitable screws 149 Figui'e 6). Each hub 146, has a de ending oss 151 adapted to receive a shoul ered'stud 152 upon which a roller 153 is mounted. A tension spring 154 has its ends 'secured to lugs or ears provided on the dependingbosses 151. and this spring functions to yieldably hold theI rollers '153 in contact with the opposedfaces of a pair4v of 'cam disks4 155, mounted on the drive shaft 69. (See Figure 13). Each cam disk 155 has a raised portion 156 adapted to engage the rollers 153 and outwardly move them to the position shown inl Figure 1 3, when the disks 155 are rotated.A Such outward movement of the rollers 153 will cause the upper curved ends of the fingers 144 to be moved from `the dotted to the full line position shown in Figure 13, which action will causethe terminals of the fingers to engage the upstanding end-portions 39 of the carton and inwardly and downwardly fold or bend them 'from the dotted line position shown in Figure 13', to the. full line position shown in Figures 12 and 13. After the ends 39 have thus been inwardly folded, the incompleted carton will be automatically and progresively advanced in"th emac'hine from the position shown in Figures12 and 13, to the position indicated at A in- Fig,-

' later.

gage thel upper portion of the die chains, as shown in Figures 5 and 6. This plate functions to retain the end-portionsy 39 of the cartons infolded position, while the carton is being moved from the position shown. in Figures 11, 12 and 13 to that shown 11n .Figures 6l and 14.

te the position shown -in Figure 14. The

function of the plunger 157 is to downwardly fold the inwardly extending endportions 39 from the position shown in Figure 13, to that shown in Figure 14. This punch also functions to square the walls of the carton so that whenl completed it will resemble the receptacle shown in Figure 15.

The upper end of the die shank is secured to a suitable cross head 158, which is plvotally connected.I by means of links 159, to an oscillatory arm 161, similar l.in construction and function to the arm 94, previously described. The arm 161 is mounted on a rock-shaft 162 mounted in the upper portion 99 of the bracket 83. A relatively shorter arm 165 is mounted on the opposite end of the shaft 162 and has a connecting rod 164 pivotally connected thereto which depends therefrom through an aperture 165 in the frame top 30. 'The lower end of the rod 164 is operatively connected to a suit able driving means which will be described Receptacle filling mechanism.

The means provided for filling the receptacles or cartons with candy or other material, and also the means provided for feeding the candy to the filling mechanism, is plainly feed tray 166, mounted adjacent one side of.

the machine, upon a suitable supporting means, not-shown. This feed tray is preferably provided on three sides with marginal upturned flanges 167, 168 and 169, which function to retain the candy units thereon as lthey are manually fed over the surface of the tray. Each candy unit, before being placed on the feed tray 166, is usually wrapped in waxed paper for sanitary purposes, as the form of receptacle here used is of the open type, as shown in Figure 15, and therefore does not offer any protection to the candy when packed therein, as shown in Figure 20. After 4the candy has thus e horizontal portion 93 of the bracket been cut into small units and preferably wrapped, as above stated, which is usually done by automatic machinery, it is placed uponthe tray 166 and arranged in rows, as4

.shown in Figure 2.A The operator will then placev thetray upon a supporting means adjacent the; machine and manually feed the candy across -the surface thereof, inv the direction of the arrow, until the leading row is brought into contact with the upturned `fla1ige1-68, after which it is fed transversely across thetray through an opening 171 and into a feed' chute 172, as indicated by the arrow. The feed chute 172 extends over the top of the machine and has its dischargeend terminating at a' point directly above thc completedreccptacle, seated in one of the .die pockets, composed of the two chains.

(See Figures 16,- 17, 18 and 19)..'

` shown in Figure '16, the feed chute 172 is preferably supported upon the machine top 30 by means of a shouldered stud 173, and is arranged in spaced parallel relation thereto so as to overhang the die pockets. An elongated discharge opening 174 4is provided adjacent the' end of thc chute, and this opening is in vertical alinement withI the empty receptacle positioned therebeneath in oneQ of the .die pockets. (Figure 16). An adjustable stop plate 175 is .mounted adjacent the end of the chute. Anadjusting screw `176having.; a knurled head 177, is mounted in a threaded aperture provided in the end wall 178 of the-chute. One end of the screw 176 is preferably turned down, as shown, to provide a reduced end portion 179 which is rotatably mounted Iin'an aperture provided in the` stop plate 175,` and is slightly headed over so as to prevent it from becoming disconnected therefrom. A lock nut 180 ismounted on the screw 176 to lock it in adjusted position. The 4stop plate 175 functions to provide a stop for the candy as it is fed into the chute so that it will be in direct alinement with the discharge opening 174 and the empty receptacle positioned thcrebeneath.

Referring to Figures 16, 18 and 19, it will be noted that the candy units, when positioned in the chute over the discharge open ing 174 and againstvthe stop plate 175, will be prevented from dropping therethrough by means of a pair of yieldably mounted gates 181 which are adapted normally to partially close the discharge opening 174, as indicated by the dotted lines in Figure` 18 and by `full lUU lLU

lines in Figure 19. These gates aremounted A ing them into the carton, prefers. ly consists of a packer plunger or ram 185 mounted 1n Va. vertical guide bearing provided in the bracket 93, direct-l7 above the chute 172. The upper end of tii the cross-head 158, as shown in Figure l, so Vthat it will be o erated each time the cross-head is aetuate by the timed oscillation of the arm 161. 'lhus it will be seen that each time the cross-head 158 is actuated, the packer plunger 185 will be downwardly moved from'the position, shown in Figure 16, into contact with the candy units positioned in the chute directly beneath. (Figure 17). As the plunger continues in its downward movement it will force-the units through the discharge opening 174 and against the yieldably'mounted gates 181, .which gates will thereby be opened to the full line position in Figure 18, and allow the candy to be inserted or acked into the re ceptacle as shown in igures 17 and 18. When the candy pieces or units have thus been packed into the receptacle, the packer plunger 185 will be returned to normal position as shown in Figure `16. A guide plate 186 is preferably secured to one end of the packer plunger to prevent the candy, remaining in the chute, from falling over onto the plunger when in the osition shown in Figures 17 and 18. A at spring 187 lis also provided to frictionally hold the candy unit in an upright position in the chute when the units at the end of the chute are being packed into a carton. This spring is preferably secured to a bridge bar 188 mounted over the chute (see Figures 16 and 17).

Means are also provided for retaining the end candy units in an upright position in the chute each time the candy is manually fed along in the chute after the pieces or units at the end of the chute have been packed into a. receptacle. Such means preferably consist of a' tension plate 189 secured to one Thus it will rea ily be seen that .by the use of this tension plate the candy lmits will be frictionally held in an upright position while being fed along'the chute over" the discharge opening 174. The tension plate 189 is adjustabl and yieldably mounted on the wall of t e chute bv means of threaded'studs 192, secured to the wall,

s plunger is secured-tov and having lnurle'd 'adjusting nuts 193 mounted thereon. A compression spring 194 is mounted on each stud between the plate and the adjusting nuts so that the pressure of the plate against the candy may be varied or adjusted to the proper degree. Guide rollers 195 are also provided at each end of the discharge opening 174 to guide the units linto the empty receptacle (sec Figures 16 and 17).

After the candy has been packed into the receptacle, as above described, and as shown in Figure 20, the intermittent drive mechanism will cause the die chains tovbe actuated which will move theilled receptacle from the position shown at B in Figures 5 and 27, to the position shown at C in the same figure?. lVhen in the latter position the receptacle will be moved in registration with an opening 196 provided at the end of the machine top30, as shown in Figures 1, 2, 4 and 6, and Will thence drop into a curved discharge spout 197 and be discharged onto a suitable conveyor belt 198, having one end mounted on a drive roller 199, carried by al shaft 201 which is rotatably mounted in bearings 202 and 203, provided in the side walls 31 and 32, respectively, of the machine frame. Thev other end of the conveyor belt 198 may be supported by suitable means, not shown. the filled receptacles will be discharged onto the conveyor belt 198, as shown in Figure 1, and may then be removed therefrom and packed into larger cartons or shipping boxes to facilitate handling in storage or transit.

A plunger or ejector 200 is preferably provided adjacent the packer plunger 185 to positivel eject the filled receptacles from the chain die pockets into the curved chute 197. This ejector is mounted on the cross In the operation of the machine head 158 and depends therefrom in spaced parallel relation to the Dm'vnlg mechanism.

The driving mechanism of this novel receptac'le-making and filling machine is shown in Figures 1, 3, 4 and 24. As shown in Figure 24 a. pulley 204 is rotatably mounted on the drive shaft 69 between a. collar 205, secured to the shaft, and a flanged coupling member 206 slidably mounted on the shaft and prevented from rotation thereon by a. feather key 207, secured to the shaft. A collar 208 is secured to the outer end of the shaft to 'provide a stop for lthe coupling member 206 when moved out of engagement with the pulley 204. Pins 209 are provided on the coupling member adapted to be received in suit-able apertures provided in the web of the pulley, thereby to transmit power from the lpulley to the shaft when the coupling member is positioned as shown in Figure 24. When the coupling iiient with the pulley and the latter willbe fi'ee to rotate or idle on the shaft.

The cams 106 and 115, actuating the carton end- folding 4fingers 104 and 113, are driven from a cross shaft 211 mounted in bearings provided in the front and rear walls of the frame. (Figures 1, 4 and 24) A bevel pinion 212 is secured to this shaft and meshes with a similar pinion 213, terminally mounted'oii the vertical shaft 108 as shown in Figure 1. A sprocket- 214 is mounted on the shaft 211 adjacent the rear frame wall 32 and has a chain belt 215 operatively connecting it with a similar sprocket 216, mounted on the drive shaft 69 (Figure 24). Thus it will be seen that whenever the drive shaft 69 is rotated the cross shaft 211 will also be rotated with the resultant actuation of the cams 106 and 115, and therefore the end-folding fingers 104 and 113. Referring to Figure 6 it will be noted that the cams, and also the cross bars 105 and yoke 114, are preferably arranged in staggered relation, so that the cam 106 will engage only the cross bar 105 and p will clear or swing over the yoke 114, and,

similarly the cam 115 will engage only the yoke 114. The cams 105 and 115 are also so arranged on the shaft 108 that the fingers 104 and 113 will be actuated in timed relation lto the movement of the die chains and the rest of the mechanism.

The mechanism provided for operating the connecting rods 102 and 164 to actuate the rock shafts 96 and 162, and therefore the plungers 91, 157, 185 and 200, preferably consists of a grooved cam member or wheel 217 mounted on the lower transverse shaft 67 (see Figures 3 and 4). This cam wheel has a cam groove 218 formed in one side or face thereof adapted to provide a track for an anti-friction roller 219, mounted on an oscillating arm 221, which is mounted on a rod 222 journaled in the side walls of the frame. A forked bracket 223 is pivotally connected to the end of the arm, and this bracket has the lower end of the connecting rod 102 slidabliy mounted therein". A collar 224 is termina ly secured to the rod, and a compression spring 225 is interposed between this collar and the up er portion of the bracket so that the r will have a yieldable connection with the arm 221. A stop collar 266 is also secured to the rod 102 above the bracket 222 to limit the movement of the rod with reference to the bracket. Thus when the cam wheel 217 'is rotated, the grooved cam 218 will cause the arm 221 to be oscillated, which will transmit a rocking movement to the rock shaft 96 as a result of it being operatively connected thereto by means of the connectin rod 102 and arni 101. Such rocking of t e shaft will-cause the forming plunger 91 to be actuated in the initial formino` operation of a receptacle, as has herein efore been described. The cam groove 218 is so shaped as to cause the downward movement of the forming plunger 91 to be interru ted when it reaches the position shown in igure 6, thereby allowing the receptacle end-forming lingers 104 and 113 time to inwardly fold the ends of the carton blank, after which the cam will complete the downward movement of the plunger, moving it from the position shown in Figures 6, 8, 9 and 10 to that shown in Figure 11, wherein it will be noted that the partially completed carton will be seated in one of the die pockets of the die chains.

. A cam groove 227, of a relatively different shape than the groove 218, is provided on the opposite face of the cam wheel 217, and functions to act-nate the connectin rod 164. The means provided for operatively connectin the rod 164 with the cam groove 227 is simi ar in construction to that shown and described with reference to the other rod 102 and cam groove k218, and like parts will therefore be indicated by like numerals. As shown inv Figure 4, the cam groove 227 and operatingmechanism functions to operate the connecting rod 164, which will cause the rock shaft 162 to be oscillated with the resultant actuation of the cross-head 158, and therefore the punches 157 185v and 200, as has been previously described. It is to be understood that the loperation of the punches 91, 157, 185 and 200, by the cam grooves 218 and 227 must be in timed relation to the intermittent movement of the die pockets, formed by the two endless chains, in which the cartons are positioned as they advance through the machine in the formation thereof. The lower transverse shaft 67 is driven from the drive shaft 69 by the intermeshing gears 71 and 72, as hereinbefore described. (See Figures 1 and 3).

The means provided for operating the conve or belt 198 is shown in Figures 1 and 4, an particularly in Figure 24. Referring to the latter figure, a sprocket wheel 228 is operatively connected to a similar sprocket 229 by means of a chain belt 231. The sprocket 229 is preferably mounted upon and secured to a hub 232 of a pinion 233, rotatably mounted on a stud 234 secured to an arm or bracket 235. The bracket 235 has a split hub 236 which is adjustably mounted upon the hub of the bearing 203, supporting one end of the shaft 201. A bolt or cap-screw 237 is provided in the split hub 236 to lock it yin adjusted position. A pinion 238 is mounted on the conveyor shaft 201 and meshes with .the pinion 233, mount- .ed on the stud 234. Thus it will be seen that iio
