SPECIFICATION forming part of Letters P E.pplication filed May 31, 1893.

['0 (LZZ whom it may concern: Be it known that we, WILLIAM H. DOBLE, residing at Quincy, in the county of Norfolk, and WILLIAM S. SCALES, residing at Everett, in the countyof Middlesex, State of :Massachnsetts, citizens of the United States, have invented certain new and useful Improvements in Machines for Folding or Setting Up Cartons and the Like, of which the following, taken in connection with the accompanying drawings, is a specification.

,Our' invention relates to a machine for folding or setting up cartons and other receptacles of a kindred nature. For convenience and economy of packing and transporting the cartons they usually comei'rom the inanufac turer in a knockdown forum-that is, the

l machine for that purpose.

flaps which form the top and bottom of the cartonare left unfolded and the body of the carton is knocked down flat. ,In this knockdown form one side flap and one end flap lie end to 'end, and the other end and side flaps also lie end to end underneath the first pair, but in reverse order. Before the cartons can be used they have to be squared out and the flaps whichg form the bottom of the carton folded.

. Theobject of our invention is to produce a We have especially intended the machine for. use in combination with a package-filling or a weighing and package-filling machine, so that it will automatically fold and deliver to the package-filling machine the cartons, paper bags, orother receptacles as fast as they are needed although the machine embodying our invention may be used independently of the package-filling machine. i

We will now proceed to fully describe our invention, the particular features of which will be pointed out in the claims at the end of the specification;

Fig. 19 shows the form of the car.- ton when in the position shown in Fig. 11 with two of the end flaps folded. Fig. 20 shows the carton after it. has been turned. to an upright position and the thirdiflap has been folded by fingers 39. Fig. 21 shows the carton after it'has been turned at right anaround and the fourth end flap has been folded ted lines showing what was the unfolded end carton has been turned. part way around.

, The unfolded or knocked down cartons are stacked in a hopper 1 and are drawn'out at the bottom one at a time. The hopper sho'uldbe of a size to fit the cartons, or it should have adjustable walls, so that thecarview of the guides 59 and, of thepneumatic from the left of Fig. 14, taken after thepasting-rolls have advanced and are in contact from the dog 57 after entering between the gles to'Fig. 20,'when the standard is turned after engagement with the incline 52-, the dot-' flap of Fig. 20 and showing thereby that the tons will be kept with even edges. The hopper is secured to bracket 5 by bolts 6. A sliding carriage 10 has flanges 11, which fit in the grooved ways 8 in the side guides 7. The guides 7 are supported on the frame 9. On the top of the carriage is a plate 2, which supports the stack of cartons when the carriage is in its forward position, as shown in Figs. 1 and 9. The plate 2 has a forwardlyextending portion 4:, which is thinner than the rear portion, so that the offset or shoulder 3 is formed. When the carriage lOmoves to its reartnost position, the plate 2 will slide back until the portion at comes under the eartons, which will settle down when the shoulder 3 is at the rear. When the carriage moves forward, the shoulder 3 will engage the lowermost carton, so that it will be carried forward on the projecting portion 4. Link 12 is pivoted at one end to the carriage 10, and at its other end it is pivoted to the upper end of bent cam-lever 13, having on its lower end pin 14, which engages with groove 15 in the As the cartons are usuallyconstructed they are rectangularin cross-section when folded* that is, when set upand they have both at the top and the bottom four flaps to close the ends. One pair of the oppositely-folding end flaps are usually folded first, then one flap of the other pair, and then the fourth flap. In order to keep the flaps in place to tightly close the bottom, they should be pasted before folding. It is unnecessary, however, to paste the fourth or outside flap. We have contrived pasting mechanism for pasting the flaps as soon as the carton is moved forward by the carrier, the cam-groove 15 of cam 16 being of such form thatthe carriage 1O slides forward at first only a part of its forward movement. Then the carriage remains stationary long enough for the pasting operation and then moves forward again to bring the carton into position for the folding mechanism. The pasting mechanism is as follows: A feed paste-roll 66 turns in a paste-box 67 and is driven by pulley U8. The two pastingrolls 69, which paste the flaps, are kept in Contact with feed-roll 66 by the action of spring 173 on lever 73 (see Figs. 1 and 2) and are kept in contact with each other by springs 70, the shafts 71 of the pasting-rolls being journaled in yielding supports 72. (See Figs. 2, 13, let, and 15.) The said yielding supports 72 are supported on the bellcrank lever 73, which is pivoted at 74, the lower end being in position to be engaged by cam 75 on cam-disk 16. On the completion of the first forward movement of the carriage 10 one of the cams 75 acts on the lever 73 to push forward the pasting-rolls 60, which engage between them th: carton and the projecting portion at of the slide-plate on which the carton is supported. The axles of the pasting-rolls yield sufficiently to include the carton 56 and plate 1 between the said rolls, but the springs keep the rollsin contact with the carton and plate. The forward movement of the pasting-rolls is sufficient for them to travel over the flaps of the carton, and then they retreat. As the carton lies on the plate one of the side flaps and one of the end flaps are exposed to the action of the upper pastingroll. The plate at has an open space at 140, (see Fig.6,) so that that one of the under flaps which lies over said opening will be exposed to the action of the lower pasting-roll, the other under flap being protected from the pasting-roll by the plate 4. After the pasting-rolls have withdrawn the carriage 10 completes its forward movement and brings the carton under the end of the lifting-lever, as shown in Figs. 1 and 2. The second cam projection 75 on disk 16 now causes the pasting-rolls to move forward again to paste the flaps which form the top end of the carton, so that they may be closed in when the package is filled. The lifting-lever has two arms 18 19 and is pivoted on the hollow shaft 20.

Said shaft 20 has its bearings in the sides of the swiveling frame 41, the side being broken away to more clearly show the lever. The arm 18 has a hollow passage-way 21 through it leading into the hollow shaft 20. The end of arm 18 terminates in a cup-shaped portion 22, having an elasticedge formed of rubber or other elastic material. A vacuumchamber 25 is connected with the end of said hollow shaft by an air-tube 124 and flexible connection 24. The tube 2% should be flexible and also have some slack to allow for the lateral swing of the arm wit-h its standard, as will be hereinafter described. The tubes are shown broken away. A three-way valve 125 controls the passage from the tube 124E to flexible tube 24. A flexible tube 126 leads also from said tube 124 to slide-plate at, with which it is connected, the said plate having an opening 141 to said tube. (See Fig. 6.) A three-way valve 127 controls the passage.

A rod 128, connected with arm 132 of valve 125, and a rod 129, connected with arm 133 of valve 127, are both engaged by the arm 18 of the lifting-lever when in its downward position to open the said valves 125 and 127 and make open communication from the vacuumchamber to the hollow arm 18 and from the vacuum-chamber to the flexible tube 126. By opening the valve 125 when the cup 22 rests on one of the cartons the suction will cause the carton to adhere to the cup and be lifted with it when the arm 18 rises. By opening the valve 127to the vacuum-chamber when the carton is on the plate 4 the suction will draw on the lower side of the carton. When the arm 18 rises from engagement with rod 129, the contraction of spring 130 will turn the valve 127, closing the passage to the vacuum-chamber and cutting off the suction on the lower panel of the carton. Before the valve 127 closes to cut off the suction, however, during the first part of the uptoo ' as soon as thecarton is partially opened, and

the carton will then be lifted.

' Fixed to the hollow shaft 20,, on which the arm 18 is pivoted, is a segment-gear 26, which meshes with rack 27. Said rack is reciprocated vertically in grooved ways in frame 4:1

by a lifting-rod 28 and causes the lifting-lever 18 10 to turn on its horizontal axis. Said rack is pivoted on the rod 28, so that the rack can rotate a quarter-turn. The rod28 passes down through hollow pivot 42, on which'frame 4.1 is pivoted, as will be described hereinafter, and through a guide 29 and has a pin 30 at its lower end which engages with camslot 31 in cam 32 on shaft 33. The arm 19 is bifurcated at its end to form bearings 35 for the fingers 31. These fingers 3 have rearwardly-projecring branches 36, connected by a tension-spring 37, which'tends to keep-the fingers 34 spread open. (See Figs. 8 and 12.) The office of the fingers is to engage with the two flaps of the carton which are to be first folded and turn them under to form part of the bottom. These we will term the end flaps, as the narrow flaps are the ones which are usually turned in first when the end of the carton is oblong in shape. As the liftinglever 18 19 turns upon its pivot the fingers 34: rise between cam-guides 38, which engage the fingers. The inside walls of these cams approach each other upwardly. On the sides of the fingers 34 are antifriction-rollers 139, which are pivoted on axes radial to the axis of arm 18. These. antifriction-rollers ride upon the sides of said arms 38 when the arm 18 rises and the fingers 34 are caused to .ap--

proach each other. Before the lifting-lever 18 19 begins to rise thefingers 34 are lower than the carton which lies on the plate 4. During the first part of the upward movement of the lever l8 19, while the opening up of the carton is taking place, the fingers 34 will rise, so that when the whole carton begins to be lifted the fingers will then be in engagement with the two end flaps. As the liftinglever continues to rise and the fingers 3i approach each other by the pressure of the cams 38 the fingers will push inwardly the end flaps of the carton. If the machine is intended to fold square cartons in which the flaps are all the same size and overlap each other when folded, it is necessary to devise means by which one of the end flaps will be folded in advance of the other, because the two will interfere if it is attempted to fold them simultaneously. This can be accomplished by variation in the form of the cam-guides 38; In order not to tear the cartons, it is preferable to have the fingers 34: bent, so that the bent portions 134: will engage with the flaps.

' There is usually a certain amount of spring pivot.

in the carbon along the folding-lines, owing to the elastic nature of the cardboard of which the carton is composed, and this elasticity tends to cause the carton to spring back out ticularly shown in Figs. 4: and 5, in which the carton 56 is represented as clinging to the cup 22 on the end of arm 18 before the arm begins to rise, the carrier-plate 4 notfbeing shown. A dog 57 is pivoted on an arbor 60, jourualed in cars 61, projecting from cup 22. When the arm 18 rises, the dog 57 will engage with the boss 58, projecting from one of the carton-guides 59, and be turned down on its The toe 62 of the dog will engage with the edge of the carton at the outer foldinglineand aid the suction devices alreadydescribed to square out the carton. After the lower suctionaction is out off the toe 62 will continue turning until it swings around into the position shown in dotted lines in Fig. 4, the carton being shown in dotted lines turned back past the right angle, giving the carton the shape shown in Fig. 17. This will break the spring somewhat, so that when the carton is again brought back to the square form, as in Fig. 18, it will retain its shape. After the arm 18 has risen far enough for the dog 57 to clear the projection 58 the holder 22, with carform and permitting the fingers 34 to fold the end flaps, as previously described. (See espeoially Figs. 2, 9, 11, and 12.) The carton will now be in the form shown in Fig. 19, two

flaps remaining unfolded. On the down movement of the arm 18 after the carton has been folded and delivered the point 65 onthe dog 57 will strike the projection 58 and turn the dog back on its pivot to its normal position. The pin 63, which projects from the dog, will strike against stop 64 to preventthe dog from being thrown back too far.

Rising from the swivel-frame il are two standards 40, to the upper ends of which are hinged the fingers 39. Springs 55 normally hold the hinged fingers 39 in the position shown in Figs. 1 and 2, projecting toward each other into the path ofthe projecting side flaps of the carton. When the arm 18 reaches nearly an upright position, the upper one of these projecting side flaps (the one which has been pasted) is brought into engagement with saidfingers 39, both fingers 39 engaging the same flap near opposite ends thereof. The

continued upward movement of the arm 18 will cause the said flap to be folded inward. The position when partially folded is shown in dotted lines in Fig. 1. When the arm 18 has rocked far enough up for the said side ilapto be folded in at an angle of about fortyiive degrees, the fingers 34: will have passed up through the contracted passage between the cam-guides 38 into a wider way, which allows the said fingers to be spread apart by the tension of spring 37 and to be withdrawn from the end flaps out of the way of the side flap, so that the side flap can be folded square onto the two end flaps which have been already folded. The carton is nowin the form shown in Fig. 20. The fourth flap yet remains unfolded. The swiveling frame 11 has a pivot 42, on which it turns in bearing 43. Pivot 42 is hollow, softha t the rod 28 may pass through it. On the bottom of the swiveling frame 41 is secured a horizontal segment-gear44, which meshes with rack-bar 45, which slides in ways in the stationary frame. Connected with'the rack-bar 45 is a connecting-rod 16, which is also connected with bentlever 4L7, pivoted at 147, said lever47 having at the end of its short lower arm a pin 18, which engages with cam-slot 49 in cam 50. Said cam 50 is mounted on shaft 17, being the same shaft on which cam 16 is mounted. When'the cam 50 revolves, the rack 45 is reciprocated in its horizontal ways far enough to give a quarter-turn to segm ent-gear eat-and swiveling frame 41, thus also turning the arm 18 and standards 40, which are carried on said frame. This turn will swing the arm 18 around to bring the carton over the table 51. "/Vhen the device is used with a weighing and package'filling machine such aswe have already referred to, this table 51 will preferably be fixed to or form a part of the weighing-machine. WVhen the arm 18 swings over, as just above described, the fourth flap of the carton strikes the inclined surface 52, which projects from the end of the table, and the said flap is folded under to complete the bottom end of the carton. The carton will now be in the form shown in Fig. 21, the dotted lines indicating the position of the fourth flap before it was folded after the carton was given the quarter-turn from the position in Fig. 20. By the same swinging movement of arm 18 the hinged fingers 39 will strike the projections 53 on the under side of table 51. This projection is so adjusted as to cause the fingers 39 to tip over on their hinges 54L sufficiently to clear the under side oftable 51 and not to interfere with the folding of the last flap when the quarter-turn of the swiveling frame occurs. This movement of the fingers 39 away from the carton is made to occur when the fourth flap has been folded to an angle of about thirty to fortyfive degrees. Extending up from the horizontal sliding rack 45 is a projection 145, and when'the rack moves to the right, as viewed from Fig. 1, to give the quarter-turn to the swiveling frame already described this projection will engage with the downwardly-extending arm 131 of the three-way valve 125 and turn the valve, so as to close the passage between the arm 18 and the vacuum-chamber and open the passage-way in the arm 18 to the outer air, so that the suction on the carton will be released. This will occur at the end of the forward movement of the rack and after the swiveling frame has completed its quarter-turn, when the carton is suspended by the arm 18 over the table 51, so that the carton will be deposited on the table with the four flaps which form the bottom completely folded.

As the flaps have a certain amount of spring in them which the paste is not sufficiently strong to resist before it dries, it is desirable to have some means to hold down the carton on its bottom to prevent the flaps from unfolding. A projection 151 from the weighing-machine extends over the table 51, on which the carton is deposited, at a sufficient height above it so that when the carton is deposited on the table said projection 151 will prevent the carton from springing up. The continued rotation of the cam 50 reverses the direction of movement of rack 45 and rotates the swiveling frame a quarter-turn backward, the standards 40 and the lever 18 19 being carried with it, and springs 55 restore fingers 39 to their normal position. The cam 16 then actuates the vertically-reeiprocating rack 27in a reverse direction to its former movement and causes lever 18 19 to descend. In the meantime the carriage 10 has been drawn back until the forward slide-plate 4 comes underneath the pile of cartons in the hopper and the bottom carton settles down with its rear end in front of the shoulder-3, which engages said carton and pushes it forward when the carriage moves forward again.

Our carton-folding machine is specially intended to cooperate withaweighing and package-filling machine and may be connected with the weighing and package-filling machine to work intermittently in unison therewith, so that a carton will be folded and laid on the table for use in the weighing-machine as fast as the packages are filled. One method of making such connection is illustrated in the drawings.

81 represents a package-moving finger projecting from an intermittently-rotating package-moving ring-such,for instance,as shown in Patent No. 556,258 to Doble and Watson, dated March 10, 1896, or in the application of G. W. Watson, filed June 30, 1897, Serial No. 642,928, in which the package-moving ring rotates through a certain are after a full package has been removed from the scales and the package moving fingers push another empty carton onto the scales, and thenthe ring automatically stops until the package is filled. In the drawings herewith the said ring is not shown. Pivoted on a support 82 is a bell-crank lever 83, which lies in the path of the fingers 81, so that when the intermittently-moving ring rotates the said bell-crank will be engaged by one of said fingers and tipped on its pivot. A connecting-rod s4. is

633,953 Y V g pivoted at its upper end to said bellcrank and at its lower end is pivoted at 85 to the short arm of lever 86, which is pivoted at87 to a part of the stationary frame. The cup-shaped disk 88 is loose on shaft 33 and is continuously 'through one cycle of its operation. The arbor 92 of the pawl 90 passes through the disk 89, and on its outer end is an arm 93, which engages with the lower end of lever S 6'once at each revolution of the disk 89. \Vhen the arm 93 and lever 86 'do so engage, the pawl 90 isthrown out of engagement with the teeth of disk 88, and the disk 89 and shaft 33 are brought to a,stop. This stop is timed to occur when the arm 18 has reached its uppermost position, carrying one of the cartons,

which then has three flaps folded and is ready for the quarter-turn to fold the other flap, as already described. ing finger 81 again moves, tipping the bellcrank 83 and lifting the rod St, the rod 86 will be disengaged from arm 93 and spring 94.- will throw pawl 90 back again into engagement with one of the teeth 91 of the disk 88.

Gear-wheel 95, which is fast to shaft 33, gears with a similar gear-wheel 96, as shown in Fig. 3, on shaft 17 and gives motion to said shaft 17 and the cams 16 and 50.

In describing now the operation of the machine we will assume it to be combined with a weighing and package-filling machine of the character already referred to, and for convenience we will begin the description at the point in the operation when the machine is in the position shown in Fig. 1, in which the lifting-arm 18 has just descended, the suctioncup 22 resting on the carton which has been fed forward and pasted, and the valves 125 and 127 are both opened to the vacuum-chamber and closed to the outside air by the downward pressure of the arm 18 on rods 128 and 129 in the manner previously described. The package-moving fingers-of the weighing-machine are now supposed to be at rest, and a oarton is on the scales being filled, and the disk 89, which, as already stated, makes one rotation at each cycle of operation, is in the midst of a rotation. Cam 32 now draws down rod 28 and rack 27, which by en gagement with segment-gear 26 turnsup lever 18 19 on its pivot. The carton clings to cup 22 on the end of arm 18 and is lifted, the suction on the lower panel of the carton through flexible tube 126 retarding the movement of that portion of the carton until the valve 127 is turned by the tension of spring 130-110 shutofi the suction. The carton will be squared out by the upward pulling of the lifting-arm 18and the suction which has been pulling down on the lower panel and by the action When the package-mow of the dog 57, and it will be preserved in its squared form by the action of the side guides 59 after the suction on the lower panel is cut off. As the arln 18 rises the fingers 34: will fold in the end flaps, and then said fingers will withdraw when they have passed up through the contracted portion of the passage between the guidecams .38. will fold one of the side flaps during the latter portion of the upward ascent of the lifting-arm, the fingers 3i withdrawing from the end flaps in time to avoid interference with the folding of the side flap. At this point the clutch S8 89 will have rotated far enough to bring the arm 93, which is on the outer end or the arbor 92 of pawl 90, into engagement with lever 86, disengaging the pawl from the teeth of disk 88, so that the disk 89 and shaft 33 are brought to a stop, and the arm 18 will stand stationary, holding the carton with three flaps folded until the two disks of the clutch are again in engagement. During this period of rest the package-moving ring of the weighing-machine is at rest and a carton is on the scales being filled. As soon as the scale-beam tips under the weight of the package the package-moving ring begins to rotate to bring a fresh package to the scales. In so doing thepackage-moving finger 81 engages bell-crank lever 83, thereby. lifting the rod 84 anddisengaging it from arm 93, so that the disk 89 again rotateswith disk 88 and the carton-folding mechanism is set in operation. The cam 50 rotates and through its interme diate mechanism, already described, causes the swiveling frame 41 to make a quarterturn, by which the fourth flap is folded, valve 125 is turned to shut off the suction through arm 18, and the carton is deposited on the table ready for use. The swiveling frame then makes a quarter-turn in the reverse direction, carrying with it the lever 18 19. Then the said lever turns down on its pivot and brings the cup 22 down onto the new carton, which is now onthe carrier-plate 4: in position to receive it, the said plate having been moved back to receive said carton from the hopper, then forward to the pasting-rolls, and then forward again to its position to meet the lifting-arm 18 by means of the cam 16, while the arm 18 has been makin g'its several movements to fold the preceding carton. The valves 125 and 127 are both turned by the downward movement of arm 18 to bring into action the suction on the upper panel of the carton through arm 18 and cup 22 and on the lower panel through flexible tube 126 and the opening in the plate 4. The carton is lifted and folded as before.

It is thus seen that when the folding-machine is eombined with a weighing and package-filling machine of the kind described as the packages are filled. The newly-folded carton need not necessarily be the next one to be filled, bntmay be deposited in a posi tion where it will in due course be carried to the proper place to be filled in regular order. We do not intend to limit ourselves to the use of the folding-machine in combination with the particular type of weighing-machine above described, as it is obvious that the weighing-machine may be varied in construction, the main object being that it shall give intermittent motion to the carton-folding machine, so that a carton shall be folded .for every carton filled. It is also obvious that the carton-folding machine may be used independently of a weighing machine. Other means than suction may be readily devised to enable the lifting-arm to hold the carton and be within the scope of our invention.

What we claim is I. In combination with a package-filling machine, a machine for setting up knockeddown packages and feeding them to the fill ing-machine, said setting-up machine having a hopper for the knocked-down packages, a suction-holder for holding the package while being opened, a valve which controls the ac tion of the suction-holder on the package, means for transferring a package from the hopper and presenting itto the suction-holder, valve-operating mechanism which causes the snction-holder to hold the package when presented to it, mechanism for opening the package, mechanism which transfers it to the package-filling machine, and mechanism which causes the suction-holder to release the package, substantially as described.

In a machine for setting up cartons, mechanism which feeds the unfolded cartons, pasting mechanism for pasting the flaps, an arm which lifts the carton, guides which square the carton as it is lifted, fingers which fold two of the flaps, mechanism which then folds a third flap, mechanism which then gives the lifting-arm a partial rotation and mechanism which then folds the remaining flap, substantially as described.

5. In a machine for setting up cartons, a pivoted lever having an arm which takes the unfolded cartons one at a time, mechanism which moves said lever on its pivot, guides which square the carton as it is lifted, fingers pivoted in another arm of said lever, guides which turn said fingers inwardly as the arm rises, said lingers engaging with two of the flaps of the carton and folding them and mechanism which then folds the remaining flaps, substantially as described.

6. In a machine for folding or setting up cartons and the like, a pivoted lever having a hollow suction-arm, a vacuum-chamber, a flexible tubular connection and a valve be tween said chamber and said suction-arm, mechanism for presenting an unfolded carton to the suction-arm, valve-operating mechanism whereby the suction-arm takes hold of the carton, mechanism foroperating the said pivoted lever whereby it lifts the carton, mechanism for folding the flaps of the carton while held by said arm and mechanism for cutting off the suction whereby it releases the carton, and mechanism for retracting the said lever, substantially as described.

7. In a weighing and package-filling machine, the combination of mechanism which opens and sets up the empty packages, mechanism which fills and weighs the opened packages, and intermediate mechanism intermittently actuated by the weighing and packagefilling mechanism at each cycle of movement thereof to start the setting-up mechanism, substantially as described.

8. In combination with a weighing and package-filling machine having an intermittentlymoving member which has a period of movement each time a package is filled, a package folding or setting-up machine having startand-stop mechanism, and intermediate mechanism which controls said start mechanism actuated by said intermittently-moving member of the package-filling machine whereby a package is folded for each cycle of movement of the intermittently-moving member, substantially as described.

9. In a machine for folding or setting up cartons, a clutch which connects the driving mechanism with the folding or setting-up mechanism,a stop which disengages the clutch at the end of each cycle of movement and causes the folding or setting-up mechanism to become inactive, a trip device which releases said stop from engagement with the clutch, and means for again engaging the clutch with the driving mechanism and ren= dering the folding mechanism again active, substantially as described.

10. In a package folding and setting-up machine, a suction device which acts on the under side of the unfolded package and a pivoted suction-arm which acts on the upper side by said intermittently-moving member of the weighing-machine, whereby each time the scale-beam tips the f olding-machine is set in operation, substantially as described.

12. In a machine for folding and setting up knocked-down cartons,mechanism which lifts the carton, mechanism which opens the carton on its folding-lines toarectangnlar form, mechanism which then engages with the package and continues the folding past the right angle and then Withdraws, allowing the carton freedom to resume its rectangular form,

and guides which check its return movement past the rectangular, substantially as described.

13'. In a machine for setting up knockeddown packages, a movable suction-arm which lifts the packages, a vacuum-chamber,a pneumatic connection and three-way valve be-- tween said vacu urn-chamber and suction-arm, means for turning said valve to open communication between said vacuum-chamber and suction-arm and render the suction-arm operative to hold the package, means for moving the saidarm wit h package attached,guides which engage with and open the package as it rises, means for closing communication between the suction-arm and the vacu nm-chamher and means for opening communication from the suction-arm to the external air, substantial] y as described. 7
