12 Claims. (oozes-g en f The present invention relates to an automatic type of machine for filling cartons or other similar containers and for effecting a partial closing of an inner liner for the same; 5

Among theobjects of the present invention is to provide a novel device for delivering at proper intervals measured quantities of fluid material to successively presented lined containers, such as fiber cartons and the like, 'and, at the proper.

,a greater number of filled cartons to an operator or operators who complete the folding and closing operations on the said containers to produce the finished packaged goods.

- .A further object within the purview of the invention is to provide -a novel combination of means for feeding the containers into position for receivin the fluid material andthe ejecting and closingmeans to, facilitate the packaging of the material whereby increased; productive capacityis assured when compared with ordinary filling machine equipment now in use.

Still another object of the present invention is tQ provide a novel arrangement of the various control mechanisms for the fluid feeding and measuring means and the ejector and closing mechanisms which provides forpositive and controllable operation thereof under all circumstances for the proper delivery of the fluid material to the containers, the ejection of the filled containers from their material receiving position, and-the partial closing of the inner liner thereofwhen received in the immediate vicinity of the operator, thus facilitating the final closing operation and the, discharge thereof from the "machine by the operator.

.A furtherobject of the present invention-is to provide a novel combined fluid" delivery mechanisnrand anti drip device, both of which are controlled by the. control mechanism for the proper sequential operation of. the anti-drip de-. vice toward the end of the delivery cycle to prevent dripping of the material over the con- .tainers as the same pass under the discharge nozzle or spout.

Still another object of the present invention is to provide a novel power drive for the various mechanisms of the device readily controllable for intermittent operation thereof by the operator at the machine; the said intermittent movement of such control mechanisms being effected by way of a one-half revolution clutch of novel construct on which is positive in its action to control with a high degree of exactitude the operation of these control mechanisms.

The invention still further includes as an object the provision of'a novel control mechanism for the ejector and folding mechanisms properly synchronizedin respect to the operation of the other mechanisms of the device to successively eject the containers from the feeding line into the environment of the operatorand to fold the panel of an inner linerfor the container. The ejecting mechanism is of such form and construc tion as to provide positioning means for the containers disposed upon the in-feed conveyor and is of'such construction as to be replaceable by similar devices, varying in size, however, to accommodate cartons ofvarious sizes and shapes.

Other objects, features, capabilities and ad: vantages are comprehended by the invention, as will later appear and as are inherently possessed thereby.

Referring now more in detail to the'drawings, adevice made in accordance with the present invention and selected to illustrate the same is shown as'comprising aframe structure, generally referred to as 2, supported upon the foundation or floor 4 and adap't'ed'to provide a mounting for the various instrumentalities and mechanisms in proper relation to one another. Since this frame is of somewhat conventional construction embodying such elements as the upright elements 8 and cross pieces 8., as wellas variousbrackets and supports, such as It], further reference to th detailed structure of this frame will not be made except insofar as is necessary in conjunction with the further detailed explanation of the various elements of themechanisms to behereafter more fully described.

The device herein contemplated is of the automatic type embodying certain instrumentalities for successively and progressively filling and said containers.

positioned by a stop and ejector'mechanism. generally referred to as #8, which operates in in-feed conveyor, generally referred to as 52, which, as will be cxplained'hereinafter, is con-,

tinuously driven for successively moving opened cartons into a position beneath the discharge nozzle 14 of a metering and delivery mechanism, generally referred-to as 16, which successively delivers'measured quantities of fiuid material to The containers are normally proper synchronized relation to the fluid delivering means for successively discharging the filled cartons onto a table or platform 2!! latterally disposed with respect to the in-feed conveyor l2. Closely associated Withthe stop'and ejector mechanism is a slider mechanism, generthe machine through the medium of a discharge conveyor generally referred to as 22;

In conjunction \vith'the various mechanisms above referred to in a general way is a control mechanism, generally referred to as 25, for operating the various elements of the device in proper sequence and which is under control at an times of the, operator at the front of the machine i The various crated through the medium of a prime mover 28in the form of an electricniotor mounted upon the platform 30- supported by the frame 2 and which, through the driving pulley :32 and belts 33 operates the pulley 34mou'nt'ed'on a shaft 36 'journaled in the spaced bearings, such as 38', secured tothe' frame 2, and upon which shaft 36 is mounted a sprocket 49 which, chain 42, operates a sprocket 44 mounted upon one end of theshaft 46. "Shaft 46 isjournaled adjacent its ends in the bearings 48 and 5!! secured to frame 2 and'disposed adjacent the top of the said frame structure 2. Mounted upon the shaft 46 are the sprocket wheels 54 and 56 which drive the conyeyorchains 58 and 60, respectively, which pass over the same and which serve as the in-feed conveyor for the cartonsto be filled by the machine. These chains 58 'and 65 pass over sprocket pulleys, such-as62, disposed in opposed relation to the sprocket pulleys 54 and 56 at the opposite end of the machine and' which are mounted upon a shaft 64 'journaled in fixed bearings 66 secured to' the frame structure 2 adjacent its-upper part to dispose said chains at substantially'the level of the-table or platform for moving the cartons successively and progressively into abutment withthestop and ejector ,mechanism wand beneath the spout H, as will be explained'more ini detail as "the de scriptionproceeds. 'j

' The discharge conveyor generally referred to elements'of the'machine are 015-- through the as .22 comprises a belt pul1ey;68 mounted'upon shaft 46 and over the peripheryof which passes the belt which extends longitudinally of the machine and passes over the belt pulley I2 mounted upon shaft I4 which is journaled in the bearings 16 secured to the frame structure .2 adjacent the: top thereof to dispose" the. said pulley I2 in opposed relation to the pulley 68 As asomewhat conventional conveyor structure, the guide elements 18 and 80 may be provided on opposite sides'of the in-feed conveyor, the-said guides I 8 having as a supplement thereto I an adjustable guide member 82 which may be moved laterally with. respect to the conveyor chains 58 and 60. Furthermore, the discharge conveyor 22' may be formed with similarguide'members,

such as 84 and 86, on opposite sides of the belt I0 to properly guide the filled cartons as the same are discharged from the machine- The control mechanism 26 is enclosed within a housing 88mounted upon the frame structure 2 by way of the channel members 90 and 92 and embodies in part a shaft 94 mounted in the housing 96 through the medium of the spaced anti-friction bearings 98 'and100 and which said housing is secured in an opening in one of the front plates of the housing 86 by the peripheral flange I02 and the stud bolts I04. This shaft extends through the outer end of the housing 96 and has mounted thereon the sprocket wheel I06 which is continuously driven through the medium of the chain I08 which passes around and is driven-by the sprocket IIO mounted uponthe transverse power shaft 46. The housing 96 is made substantially'fluid-tight at its inner end by way of the cover plate II2 secured thereto as by means of the stud bolts II4 to prevent loss of lubricant which is retained within the housing 68 for the various control elements to be hereinafter described. Adjacent the outer end of the shaft 94 is a gasket or washer I I6 of leather, or other flexible material, to preventthe ingress of dirt and other foreign material into the bearings' for said shaft.

The power drive half revolution clutch, generally designated as I I8, the details of which will be hereinafter more fully described, but which includes a clutch member I20 fixed to the inner end of shaft 94 and a clutch member I22 fixed tothe inner end of the shaft I24 in substantial alignment with and driven by the shaft 94 through the clutch H8. The shaft I24 adjacent its inner end is mounted for rotation in anti-friction bearing I26 supported within bearinghub I28 of a partition member I30 extending transversely of the housing 88 and formed integral with the opposed walls thereof. The shaft I24 has its outer end journaled in the anti friction bearing I32 mounted in the bearing hub I34 of the rear partition wall I36, the said shaft being positioned by means or the adjusting locknut I38 threaded t0 the extreme end of said shaft I2 4. The entire journal bearing at this end of the shaft is suitably enclosed by the closure cap I40 secured to the end wall I36 as by means of the stud bolts 142 orrthe like.

, Mounted upon the shaft I24 are the cammem bers I44, I46 and I48 constituting control elements for certain of the mechanisms, and the structure of which will be hereinafter morefully described; i

The control mechanism further embodies a shaft I50 extending substantialyparallel to the through the shaft 94 for the control mechanism is effected by way of a oneshafts 94 and I24 and which is rotatablylmounted through the medium of the spaced. bushings I52 and I54 in the sleeve I56 journaledlthr'ough the medium of a bushing I58 in the bearing hub I60 formedin the front plate of the housing 88. The shaft I56 and sleeve I56 are protected against excessive wearby virtue of the retainers I62 and I54 suitably mounted, as shown inFigure 7, in the sleeve I56 and the bearing hub I60, respectively, to prevent the ingress of dirt or other foreign substances into the environment of said shaft and sleeve. The assembly atthe inner end of the sleeve I56 is positioned by means of. the collar I66 secured to the shaft I50 by .the pin I68. Shaft I50 transmits rotary movement thereof to a lever I10 connected to the shaft at its outer end and which lever operates the valve of the material-feeding means, a will be'hereinafter more fully set forth. Keyedfto the rotatable sleeve I56 at its outer end is a lever I'I2 pivotally secured at its opposite end to a connecting rod II4 which in'turn is connected to the foot pedal as at I16 whereby control movements from the pedal are transmitted to saidrotating sleeve I56 to cause angular displacement of the clutch control element H8 which is secured asby means of welding I or the like to the inner end-of said sleeve and which projects toward and serves as a means of con trolling the clutch II8. :Theinner endof shaft I50 is journaleddn-a bushing I82, which in turn is mounted in' the bearing hub I84 provided in the partition member I30. The bushing I82 is retained in operativ'e' position with the bearing hub [84 by means of the collar I86 secured to the shaft by the pin I88. The shaft I50 extends through the bearing hub I84 and has mounted on its inner end the hub 190 of the cam follower arm I92 which is provided at its other end with'the transverse stub shaft I94 upon which is. mounted acam roller I96 operating within a cam groove I98 0f the cam I44, whereby movement of shaft I50 takes place in proper coordinated relation to other elements of the control-mechanism to operate lever I10, all as will be hereinafter more fully disclosed. Washer 200 is provided between the hub I and thebearing hub I84 toproperly adjustthe shaft I50 and to take up wear between hub I90 and the bearing hub I814. q 1 The construction of theone-half" revolution clutchis morereadily comprehended by reference to Figures"? and 9 to15inc1usive. The clutch member I20 is formed on its face with a plurality of teeth 202 adapted to receive the teeth 204 movement withinsuitable openings or recesses provided in clutch member I22 andis normally urgedoutwardly with respect to said clutch member I22 through the medium of the coil springs 2| 2 whereby the said paWIS, under the impulse of springs 2I2, will engage the teeth" 202 of clutch memberIZO. p i I Since the present invention contemplates the intermittentoperation ofthe various mechanisms controlled by cams 'I44, I46 and I48,and then only under direct'control of the operator through the mediumof the pedal I16, novel means ispro "vided for normally holding the pawl clutch ele ments 208 and2I0 out of operative engagement with the teet of clutch member. I20, I the said interlocking of the pawl clutch elements with the teeth of clutch member I being effected only as desired and upon operation of the foot pedal I18 by the operator. One of such control elements has been referred to as I18, and since intermittent half revolutions of the shaft I24 are desired, as will later appear, a second control element 2I4 is provided in opposed relation to control element I 18 and which is mounted by way of the bracket 2 I 6 to the housing 88.

The movement of the control element I18, as hereinbefore described, takes place upon angular movement of the sleeve I56. The pawl clutch elements are of similar construction, and while the control elements I18 and 2 I 4 ar of somewhat similar construction, nevertheless there are some differences as will appear as the description proceeds. The control element I18 is formed with a cut-out formed in part by the stop shoulder 2I-8 and in part by the cam surface 220. When the control element I18 is in its normal position, the

same is in the way of the pawl clutch element 208 with its under curved surface corresponding essentially to the surface 222 of the control element 2 I4 bearing over the surface 224, and with its cam surface 220 in engagement with the cam surface 226 of the pawl clutch element 288. Abutment stop 2I8 is in engagement with the stop shoulder 228 of the pawl clutch element 208 when the clutch is disengaged and control element I 18 is in its normal position. When these elements are in cooperative relation, the cooperating cam surfaces 220 and 226 cause an inward movement of the pawl clutch element 208 against the compression of spring 2I2 to maintain the tooth 204 out of engagement with the teeth 202 of the clutch member I20.. The control element 2I4, while similar in construction to the control element I18, does not have a stop shoulder corresponding to stop 2I8 of control element I18. Thus, while the pawl clutch element 2I0 is moved by the control element 2I4 simultaneously with movement of pawl clutch element 208 by the control element I 18, there is no positive interlock between these elements and control of the clutch is through the control element I 18.

When it is desired to transmit motion to shaft I24, the clutch element I 18 is moved through the operation of sleeve I56 to disengage stop shoulder 2I8 from the stop shoulder 228 and to disengage cam surface220 from cam surface 226, thus permitting the pawl clutch element 208, under the impulse of spring 2I2, to engage a tooth 282 of clutch member I20 to couple shaft I24 with shaft 94. Simultaneously with the movement of pawl clutch element 208, pawl clutchelement 21l0-rides over the cam surface 220 of the control element 2I4, and under the impulse of spring ZIZ likewise engages a tooth 202 of clutch member I20.

In order to assure proper and smooth operation of the clutch mechanism, thev opposed faces 222 of the said control elements I18 and 2I 4are curved as disclosed and cooperates with the curved surfaces, such as 224 and 230, of the pawl clutch elements .288 and 2I0. Y The cooperating surfaces 220 and 226 of the clutch controlelements and the pawl clutch elements are developed as screw surfaces to facilitate proper operation of the said pawl clutch elements into and out of engagement with the teeth of clutchmember I20.

The present clutch mechanismalso embodies a particular form of tooth structure-for both the clutchmember I20 and the pawl-clutch elements 208 and 2I0, including the cooperative radial faces as at 232, whichassures aipositive drive in both directions, thus-preventing over-riding of the clutch member I22 in respect to clutch member I20. Furthermore, the clutch control element 2 I4 is provided with stop 234 which, when in cooperative relation with either of the pawl clutch elements 208 or 210, prevents reverse rotation of the clutch member I22 which might otherwise take place in that the springs 2I2 have a tendency to cause this reverse rotation by their application of an axial force to the pawl clutch elements. i f m In order to maintain clutch control element I18 in cooperative association witheither of the pawl clutch e1ements'208 or 210, the said clutch control element extends from the sleeve. I58 through a U-shaped bracket 236 connected'to a wall of the housing 88, the said controlelement I 18 being urged forwardly into cooperativegrelation with either of the pawl clutch elements 208 or 2I0 by a coil spring 238 embracing the positioning elements 240 and 242 at its opposed'ends which are connected to the control element I 18 and the wall 7 244 of housing 88, respectively, and abutting said controlelement I18 and wa11244. 7

Movement of'the foot pedal i16 through the medium of the connecting rod I14 and lever I12 v angular displacement of sleeve I55 which v is transmitted to the control element I18 which,

against the movement of coil spring238, becomes disengaged frorn either'of the clutch elements 208 or 2H]. Upon releaseof the foot pedal I16,

however, the control element I18 is returned under the impulse of spring 238 intolposition to intercept either of the pawl clutch elements 203 The metering and delivery mechanism I6 in- 1 cludes a double-acting metering cylinder 246 mounted as indicatedupon the bracket I0 of the frame structureZand which has afreetfioating piston for measurin and delivering through the pipe 848 quantities of fluid materialto the discharge Ih'TZZIe I4, the device in the present instance being designed particularly for delivering lard in fluid condition to the containers or cartons successively delivered into position beneath the end of the no'zzleor spout I4 for receiving charges of said lar d ,a1though it is contemplated that the machine may be used for packaging other materials if seennt to do so.

This fluid measuring device is controlled by a four-way valve 250, which'in turn is controlled through a uni ersal linkage'252 connected to the valvestem 25! at one end by the operating lever 253 and to the end of thevalve lever I10, whereby the operation of the fluidmeasuring device is effected in proper sequence withthe other operating mechanisms-of the device, itfbeing understood, of course, accordance with the previous description, that thefoperation of lever I10 is in accordance with the angular displacement of shaft I which takes place in accordance with the movement of cam "I 44 operatingupon the cam roller I915.

The spout or nozzle M, as previously alluded'to, has angular displacement as shown particularly in Figure 5 of the drawings, and in order to accommodate such movement the said spout or nozzle, as more particularly shown in'Figure 4 of the drawings, is, provided with a hub 254 embracing the and of the pipe 256; which is connected to the pipe conduit -248ethroughthe T-connection 258. Th s n -peq fi s mounted in the bearing 260. secured tots top of theframe structure 2, and

not only positions the nozzle or spout, I 4, but

likewise the anti-drip mechanism 262 to be later described. Theend of th-e pipe 2 56 i closed as at 264 and is provided with a threaded extension 266 adapted to extend through an end wall 268 of the nozzle hub 254 and through the medium of an interposed washer 210 and a lock nut 212 is adapted to position said hub with respect to the pipe or conduit 256. Closure cap 214 threadedly engagin the hub 254 at one end is provided to enclose the end of this assembly to prevent leakage and to provide against the ingress of any dirt or foreign substances therein. The opposite end of this assembly is likewise provided with a closure; cap 216 threadedly engaging an opposed end of hub 254 andembracing a gasket or washer 218 to-effect a tight'conneotion at this point.

The discharge conduit 256 about which the spout 288 is connected to the upper end of rod 288 extending downwardly through the housing 88 and journaled at one end in the bearing gland 290. This connecting rod 288 is secured'to the upper end of a saddle 292 straddling the shaft I24 and which is provided with a cross-head 284 provided -v with a cam roller 286 operable within the cam groove 2880f the cam I46. This cam I46, through the medium of the cam roller 286 and saddle 292, causes reciprocation of the connecting rod 288 to impart angular movement to the spout I4 in predetermined sequence in the fluid delivery cycle, the spout [4 being in its lowermost position when delivery of fluid material takes place, and the upward movement being effected after delivery of the material to provide clearance for movement of the filled oontainerinto ejecting position and movement of an empty container into filling position.

Movement ofthe ejector and slider mechanisms is secured by a lever 308 mounted on the upper end of shaft 362 extending downwardly impart reciprocating movement to the piston 322 when the same is operated. The bell crank lever 328 is further provided with an upstanding leg 336 in the way of anextension 338 for the lever 360, so that when the lever moves into its dotted line position as shown in Figure 2 of the drawings; the bell crank lever-328 is given a quick move ment counter-clockwise; as viewed in Figure 5 of the drawings, to move piston 322 downwardly; thus creating.asuctiondrawing :fluid from the end of the nozzle back into the discharge system to minimize dripping at the end ofthe filling cycle. This fluid material sucked back 'into the system by operation of the piston 322 of course is put back into thelsystem at: the beginning oi the next filling cycle through the -action of the spring 324. H

The combined stop and ejector mechanism' I8 is in the form of a movable stop 34oihavingia leg 342 extending transversely of the conveyor i2 and another leg 344 spacedlongitudinally with respect to the leg342and extending innormal relation to a longitudinally. disposed leg s 346; This movable stop member is adjustablysecured as by means of the wing nut and bolt assemblies, generally referred to as 348, to the "cross-head assembly 358 secured at the ends ofithe parallelly disposed rods 352 and 354 mounted for sliding movement in the fixed guides 356 and 358. Immediately above, but independently of themov able stop 340 is a sliding blade 36ll'which, through the medium of the wing nut and bolt assemblies 362, is adjustably secured to. the cross-head 354 mounted at the end of the parallelly disposed rods 366 and 368, likewise slidably mounted in the fixed guides 356 and 358. i

This shaft 302 has a follower arm 352 connected adjacent its lower end, which carries a shaft 3 l4 upon which is mounted a cam roller 316 adapted to cooperate with a cam l groove 3i8 formed in the periphery of the cam 7 I48. Through the medium of the cam I48 the shaft 332 is rotated in predetermined sequence to and therefore in direct communication. with the discharge conduits 248 and 258. This cylinder is provided with a piston'322 spring-pressed upwardly by means of the coil spring 324 and the operation of which piston is effected by one leg 326 of a bell crank lever 328 which is pivoted as at 336 to the closure or container structure 88. The arm 326 has its free end extending through a slot 332 of the cylinder 320 and enages in the slot or recess 334 of piston 3 2 to of the, lever 318 which is 'pivotally connected as at 380 to thecross-headw364; thisimovement of lever 318 beingimpartedwbywaulinkx382 con nected intermediate .theends of lever 318 and "having a pivotal;connectionwith the bracket 316. The other end of lever 316, as. at- 384, is

pivotally connected to a link 386 which in turn in pivoted as at 388 to the bracket 396 extendindg laterally ofthe housing 88; p 1 l Referring more specifically to Figures 16 inclusive, wherein certain of the parts immedi ately hereinabove described are shown somewhat: diagrammatically, it will, be notedthat the stop member 340 has various operative positions transversely of the in-feed oonveyor l2. As is well understood, one form of container which may i formed with anupper open end, the side walls,

forming the liner extending above the upper open end of the carton 392, all as clearly shown;

in Figures 19 and 20 .of the drawings. These cartons with the liner disposed therein are fed onto the conveyor I2 and are carried into: a position such as shown in Figure 16 whereby the foremost carton is disposed directly beneath the open end of the spout l4. When this foremost;

carton is in. the position disclosed in Figure 16, the end of the spout has been lowered into the interior of the liner to deposit a measured quantity of the fluid in the carton. While the conveyor I2 is continuously operated, nevertheless the foremost carton is temporarily arrested in its movement on the conveyor by the stop memher 349' which, when the foremost carton is moved into receiving position, has its leg M2 disposed in respect to the conveyor 52, as shown in Figure 16, so as to act as a stop member for said foremost carton.

After a dispensing operation has taken place, the nozzle I4 is angularly displaced in accordance with the previous description, and the movement of the rods 352 and 354 is such as to retract the stop member 340 from its engaging relation with the end of the carton being filled, all as disclosed in Figure 17 of the drawings,

wherebythe foremost container which has then been filled with fluid material is picked up by the conveyor I2 and moved into engagement with the stop leg 344 of said stop member 340. Simultaneously with the movement of this foremost carton,.the next adjacent carton to the rear thereof moves into filling position directly beneath the discharge end of the spout I4, at which time the control mechanism is operated to lower the spout to discharge material into said carton. Simultaneously with the filling of the next succeeding carton, all in accordance with the above disclosure, the rod 3'52 and 354 are moved through the medium of lever 390' and link 3') to engage the first filled carton above doscribedi'to move the same laterally from the conveyor chains 58 and 60 and onto the table or top 20, as shown in Figure 18 of the drawings. During this movement of stop member 340, the leg 342' thereof, while moving laterally with respect tothe next immediate carton being filled, nevertheless is of such a length that it still provides a; stop member for said carton.

During movement of the stop member 34'!) for ejecting the filled cartons, the sliding blade 3% is moved transversely of the conveyor I 2' through the medium of the rods 36S"and 368by way of' the linkage hereinabove described, into engaging relation with the front panel 398 of the liner, all as disclosed in Figure 20 of the drawings, to fold said panel downwardly into substantially horizontal engaging relation with the material contained within the carton, and simultaneously effecting a fold of the end panels, such as 4%,

example, upon operation of the shaft I24, cam Hit causes rotation of shaft I 50 through the medium of the cam rod' I92, which rotation of shaft I50 causes movement of lever III]. This lever, through the universal linkage 252, operates the conventional four-way valve 250 to operate the measuring device I6 to deliver through discharge pipe 2'48 a measured quantity of fluid material through the discharge nozzle I4, as hereinbefore described. This same rotation of shaft 524 operates cam I 45, which, through the medium of roller 296, causes reciprocation of rod 288, which raises and lowers the spout I4. This same movement of shaft I24 further causes rotation of cam i it, which operates through roller 3I6 to of the lever 3t!) which, while having the primary function of operating the stop and ejector mechahisrn, as well as the mechanism for partially folding the liners, has, in addition, the secondary function of moving the bell crank lever 328 to operate the anti-drip mechanism at the end of a filling cycle;

As is apparent from the above description, the shaft i2 2 is stationary in a definitely fixed position at the end of one-half revolution. Inasmuch 7' as the operator releases the pedal I'Ifiafter each operation, clutch'element I18 has been released, so that at the endof' the cycle of operation of shaft I24, the clutch H8 is automatically disengaged. Th shaft 84, how-ever, drivenrthrough the sprocket I96, continues to rotate during the operation of the machine. 7 It is to be noted that the cam I 38 which operates'the lever 380, and

livery of a full charge of fluid material'from the ,metering cylinder 246 at each one-half cycle of the valve movement.

For each predetermined volume of fluid delivered by themetering cylinder 258, however, the filling spout I4 and carton which facilitates further folding of the liner and closing of the top flap 394 of the carton. Upon ejection of the filled cartons onto the table 26; with the front panel of the liner folded as described, the operator standing in front of table 7 20' can then complete the folding of the liner and the closing of the flap of the cartons as the same are successively ejected from the in-feed conveyor, after which the same may be placed in contact with the belt I'll of the take-away conveyor for discharge of the same from the machine.

As hereinbefore alluded to, the operation of the device in accordance with the immediately above description takes place intermittently when the operator presses upon the pedal I16. This initiates operation of the one-half revolution clutch II8, causing a one-half revolution of shaft I24,

which operation affects th other control elements to bring about certain operations of the various instrumentalities in proper sequence to produce the results hereinbefore described. For

through a full cycle. i
