STANDARD SEALING EQUIPMENT CORPORATION OF NEW YORK PACKAGING MACHINE Application filed'January 19, 1928. Serial No. 247,844.

In my co-pending application, Serial No. 152,357, patented February, 21, 1928,

ejecting the superposed layers into a carton or box, the box or carton bein ejected from the machine when it is filled with containers.

It is one of the objects of the present invention to provide improved means for receiving the carton, or box as it is ejected and when filled to deliver the same to a conveyor 01' support, thereby avoiding possibility of injury to the carton or box as it is delivered from the machine and also to facilitate in the handling of the filled carton. y

In the said co-pending application there is also described improved means for feeding the containers into the machine so as to be delivered to the carrier which causes the cartons to be superposed, the; operation of the carrier being automatically controlled by the articles being fed by the conveyor.

It is another object ofthe present invention to provide improved means for arresting the articles as they are being fed, and improved means whereby the said arresting means will operate automatically to control the operation of. the said carrier.

To the attainment of these ends and the accomplishment of other new and useful objects as will appear, the invention consists in the features of novelty in substantially the construction, combination and arrangement of, the several parts, hereinafter more fully described and claimed and shown in the accompanying drawings illustratingthis invention, and in which- Figure 1 is a front elevation with parts omitted and parts broken away ofa machine of this character constructed in accordance with the principles of this invention.

Figure 2 is a view taken on line 2-2, Figure, 1, with parts omitted.

Figure 3 is a view taken on line 3-3, Figure 1, with parts omitted.

Figure 4 is an enlarged detail sectional view taken on line 4-4, Figure 3.

Figure 5 is a view taken on line 5-5, Figure 1, with parts omitted.

Figure 6 is an irregular sectional view taken on line- 6-6, Figure 5.

Figure 7 is a detail irregular sectional view taken on line 7-7, Figure 6, with parts omitted.

Referring more particularly to the drawings the numeral 10 designates suitable spaced uprights forming a supporting structure and arranged at convenient positlons are a plurality of tubular discharge outlets or members 11.

These tubular members are spaced from 1 each other (seeparticularly Figure 7) for any suitable distance so as toallow a carton to be sleeved over each and into which carton the containers are adapted .to be placed, the carton being removed from the respective tubular members by the containers being placed therein.

Arranged within the supporting structure so as to extend across the space therebetween and journaled in suitable bearings are shafts 12 and 13 arranged one above the other a suitable space. Carried by the respective shafts and preferably adjacent the inner faces of the up rights 10 are sprocket wheels 1 1-15. a

An endless flexible member 16 passes over the espective co-operating sprocket wheels T OFFICE 14-15 and these endless membersare preferably formed of links pivotally connected togetherby pins or pivots 17 which are adapted to enter the spaces between the teeth of the sprocket wheels -as the sprocket wheels are rotated.

Carried by the links are members 18, and

The members i 18 extend across the space between the endless members 16,'while the pins 17 preferably extend laterally from the links only a sufficient distance to be seated in the 's'paces or recesses between adjacent teeth of the sprocket wheels. The carrier thus formed may be provided with anydesired number of blades or members 18 that the containers may be fed into the -carrier in an upright positionand. as the carrier is intermittently operated the containers will be advanced by the respective members 18 so that the bottom of the containers will move along a guideway 19, preterably formed on an are described, from the axis of the shaft 13. This guideway may be constructed in any suitable manner and ar-- p is operated.

Y ranged along theguideway 19 is a member- 20 which co-incides with the spaoejbetween the tubular members 11 (see particularly Figures 5' and 7) so as to divide the supply of containers and direct them into the respective tubular members 11.

The members 18 are provided with cut away portions. 21 into which cut away portions the member 20 projects, as the carrier As the containers are elevated'by the members 18 they will, when they reach the tubular members 11, be ejected from the members 18 into the tubular member 11 ,in a manner .to be hereinafter set forth, to bedelivered into a carton or box 22. The carton 22 is sleeved over the tubular,'member 11 and disposed above the member 11 and supported by-arms 23 pivotally mounted as at 24, is a bar or rod 25 which restsupon the top of the tubular member 11. This bar or.- rod 25 is disposed at an angle to the horizontal so that when the carton 22 is sleeved upon the tubular 1 member. 11 the flap 26 of the carton will be deflected upwardly and thereby permit the carton to beproperly-placed upon the tubular member and to support the flap.

Disposed adjacent the tubular members 11 are tracks or guides 27 (see also Figure 1), within which tracks rollers 2829 that are connected with a-member 30 are adapted to travel, the outer extremity 31 of the tracks being closed. and the upper-portion is prothe position shown in Figure 5, serving as a support for the bottom of the carton, the portion 34 engagirfg the side faceof the carton while the portion 35 abuts the outer face of the bottom of the carton. The member 30, as the carton is filled, and as it is ejected from the member 11 during the filling of the carton, will travel in the tracks 27 until the roller 29 abuts the closed end 31 of'the tracks. At this timethe roller 28 will be in alinement with the opening 32 in the upper part of the track. The parts will be in this position just at the time when the carton 22 is disconnected from the tubular member 11. The weight of the containers in the carton 22 will then cause the member 30 and the extension 33 thereof to rock about the pivot of the roller 24, the roller 28 then passing through the opening 32 until the parts assume the position shown'in Figure 2. During this movement of the member 30 and the sup orts 3435 the carton will be supported y the members 34-35 and as the member 30 turns about the pivot of the roller 29 the filled carton will be delivered from the members34 35 upon a support 36 to be conveyed away. During this deliverymovement of the filled carton from the tubular member 11 on to the support 36, the carton will be turned uprightly on to its bottom from its side position, as shown in Figure 5. If desired aweight 37 may be connected to the end of the member 30 to assist in counterbalancing the members 3435.

Any suitable means may be provided which will operate as a cushion for the movement of the members" 3435 from the position shown in Figure 5 to the position shown in Figure 2. To that end there may be provided a dash pot embodying a chamber 38 which is pivotally connected at one end as at 39 to anysuitable support. Movable in the dash pot is a piston connected to a piston rod 40, the outer end of which is pivotally connected as at 41 with the members 3435.

Thus it will be seen that when the carton is filled and is ejected the weight of the filled carton will rock the members 3435 and 30 about the pivot of the roller 29 to deliver the filled carton, and as these parts are being rocked the cushion will control the delivery of the filled carton to the support 36.

After the filled carton has been thus delivered, it is necessary to rock the member 30 together with the members 3435 back to its original position about the pivot of the roller 29 so that the roller 28 will again' enter the opening 32 in the track 27, after which the member 30 may be moved backwardly upon the tracks 27 until the member 35 engages the bottom of the carton sleeved upon the tubular memberll.

Motion is imparted to theendless carrier embodying the links 17 and members 18 by means of a gear 42 (see particularly Figures 2 and 3) carried by the shaft 12 for rotation therewith, and this gear 42 meshes with a pinion gear-43 loosely mounted upon a shaft 44. Secured to the gear 43 for rotation therewith and loosely mounted upon the shaft 44 is a disc45 which has pivotally mounted thereupon and for rotation therewith a dog 46 which is controlled by a spring 47. Loosely mounted upon the shaft 44 and in proximity to the disc 45 is a toothed or ratchet wheel 48,

and connected with the ratchet wheel for rotationtherewith and loosely mounted upon which latter is carried by the disc 45, motion the shaft 44 is a sprocket gear 49. An endless sprocket chain 50 (see particularly Figure 2) passes over the sprocket gear 49 and also over another sprocket wheel 51 to be hereinafter described. One run of the sprocket chain-50 also passes over a sprocket wheel 52 loosely mounted upon the" shaft 13 and to which sprocket wheel 52 a pulley 53 is connected for rotation therewith so that when the pulley 53 is rotated from any suitablesource of power (not shown) motion will be imparted to the sprocket chain 50.

It will therefore be seen that when the dog 46 is in engagement with the ratchetwheel 48,

will be imparted to the pinion gear 43 by rea son of the fact that as the sprocket wheel 49 is rotated,the ratchet wheel 48 will also be rotated and this ratchet wheel 48 will be locked to the disc to rotate with the latter through the medium of the dog 46, which will cause the pinion gear 43 to impart a rotary motion to the gear 42 and the shaft 12 so that the carrier 16-18 will be moved so long as the dog 46 remains in locked engagement with the ratchet 48.

' It is desired, however, that the carrier 16-18, shall have only an intermittent operation and therefore it is necessary to provide means which will, at predetermined times in the cycle of operation of the machine, move the do 46 out of looking or activeengagement with respect to the ratchet 48 so as to unlock the inion gear 43 and disc 45 with respect to t 1e sprocket gear 49.

This is accomplished bymeans of a trip 54 (see particularly Figures 2 and 3) which is adapted, at predetermined times in the cycle I of operation of themachine, to be positioned in the path of movement of the tail 55 of the I dog 46, 2 and or in the position shown in Figures 3.

The disc 45, when locked for rotation, will be moved in the direction indicatediby the arrow, and as-the trip 54-is arranged within the path of movement of the tail 55 of the dog 46, it willbe manifest that when the tailstrike's the trip the dog 46 will be melted aboutits pivot with respect to the disc 45 against the stress of the spring 47 and thereby not only unlock the disc with respect to thesprocket gear 49, but will hold the disc will render the dog 46- inoperativeupon each complete revolution of the disc 45 so that the carrier 1618 will be given one step'of rotation. p

. Obviously the extent of movement of such step will be controlled bythe ratio or pro portion between the .pinion gear 43 and the gear 42 which is connected with the shaft 12.

In the present form of the invention the ratio is nine to one, so that 'upon each rotation of the pinion gear 43 the shaft 12 will be moved a step equal to one-ninth of the complete rotation of the shaft.

The operation of the carrier 1618 is controlled by the containers as they are being fed intothe machine and this is accomplished in the following manner. The containers are fed into the machlne by means of anendless conveyor 57 (see particularly Figures 1, 6 and 7 of any suitable type, here shown as an endless flexible conveyor, one end of which moves over a suitable support 58 and the runs of the conveyor are such that the containers will preferably rest upon their ends in an upright position there- 'upon, the conveyor passing'over suitable sprocket wheels 59-60.

The sprocket wheel or pulley 59 at one end of the conveyor is disposed within and spaced only a comparatively short distance from the inlet side of the machine, as shown more clearly in Figure 6, and an additional 6 support 60 is arranged in the machine ad U jacent the surface of the upper run of the con veyor and extends in alinement with-such run to the other side of the macl 1ine,"so that as the containers shown in dotted lines in Figure 6 and indicated by. the reference numeral 61,

are fed into. the machine they will pass from the conveyor 57 upon the support 60.

Imorder to arrest the advancing movement of the containers 61 as they are fed into the machine by the endless conveyor 57, and when a predetermined number of containers have been placed in the machine, there 1s provided a stop device 62' (see particularly Figures 5 and 6) which is pivotally mounted as at 63. The extremity 64 thereof is adapted toswing across the conveyor 57 and into .the path of movement of the advancing containers.

This stop 62 is operated automatically and is adapted to be positioned just at the time that the carrier 1618 starts to'move.

To that end there .is provided a member 65 which is pivotally mounted at one end as at 66. The other end 67 of the member 65 projects into the path of movement ofythe i p1ns 17 on the endless member 16. A link 68 pivotally connects the member 65 with the arm or extension 69 on the stop 62. A

spring 70 is connected by one end to the member 65 and is anchored by its other end to a fixed support. The spring 70 tends normally to move the member 65 against a stop 71 so that the extremity 67 ofthe member will project into the path of movement of the pins 17.

' Thus it will be seen that when the carrier 16-18 moves one step of movement in the direction indicated by the arrow in Figure 5, one of the pins 17 will engage the end 67 of the member to lower the end of the member and will, through the medium of the links 68, swing the stop 62 about its pivot from the position shown in full lines in Figure 5, so that the portion 64 will project across the adjacent run of the endless conveyor 57 and into the path of movement of the advancing receptacles.

As soon as the pin 17 passes off the end 67 of the member 65, which will happen just at the completion of the movement of the carrier, the spring '70 will return the member 65 and thereby withdraw the portion 64 of the stop 62' to permit a further supply of I containers to be fed into themachine.

The operation of the carrier is controlled by the containers or receptacles'61 when a predetermined number have been supplied to the machine, throu h the medium of amember or abutment 772 (see particularly Figures 6 and 7) which is arranged within the machine adjacent the side opposite to the inlet side to project over the support 60 and within the path of movement of the advancing container 61. The member 72 is connected to a member 73 which is pivotally mounted intermediate its ends as at 74' to a suitable support 7 5. Another member 76-is pivotally mounted by one end preferably upon the pivot 74 so that it will have a movement independent with respect to the member 73. A spring 77 is connected by one end to the member 76 and by its other end to the free end of the member 73 and the spring 77 tends normally tomove the member.76 about its pivot 74 to hold the same against a stop-7 9 carried by the member 73.-

An additional spring 80 is anchored by one end to the member 72 and by its other end to a fixed support and tends normally to move the member 73 about its pivot 74 so as to return the member 73 to its normal position.

The member 76 also controls the operation of the carrier 1618 through the medium of a bar or rod 81 (see particularly Figure 3) which is pivotally connected as at 82 to one end of the trip 54. This member 81 passes loosely throug nected thereto or formed thereon a shoulder 83, and the bar 81 is adapted for vertical movement with respect to-the member 76.

' Connected with the sprocket 51 through the medium of a shaft 84 (see particularly Figures 2 and 3) is a cam'member 85 which rotates with the sprocket and'is provided with suitable cam surfaces 86 which are adapted to engage a roller 87 carried by an arm 88 that is pivotally mounted at one end as at 89. This arm is adapted to be reciprocated about its pivot89 as the member 85 is rotated.-

The shoulder or element 83 on the bar ormember 81 is adapted when the latter is the member 76 and has conf moved laterally or to the right as shown in Figure 3, to be positioned in the. path of movement of the end 90 of the arm 88 so that when the arm 88 is then raised about its pivot 89 the end 90 will engage the shoulder or formation 83 to raisethe bar or member 81 and thereby rock the trip 54 about its pivot 56 so as to permit the spring 47 to move the dog 46 into engagement with the ratchet wheel 48. Thiswill lock the pinion gear 43 for rotation with the sprocket gear 51, with the result that the PlIllOIl gear 43 which meshes with the gear 42 will rotate the latter and thereby advance the carrier 16-18. 7

By reason of the member 76 being pivotally mounted, the'barior member 81 will be given a lateral'movement when the member 72 is'fnoved by the incoming receptacles or containers and as the member 73 is moved about its pivot 74.

As soon as the swinging of the memb er 81 to a sition that the shoulder or formatio'n 83 w1ll be out of the path of movement of theend 90 of the arm 88,'the carrier will be arrested in its movement. and the member 77 will be re-' tur 'll lled by the spring 80.;

tors 91 which are actuated by means of links 92 (see also Figures-2 and'3) operated by means of an eccentric 93 with which an ec- The ejectors are moved forwardly by the dog '46 is released by the packages" or J containers are ejected from the members 18 ofthe carrier (see particularly Figures 3 and 5) by. means of 618C- rotation of the eccentrics 93 and for that pur pose there is provided on the shaft 13 a ratchet wheel 98 which rtates with the sprocket gear 52.- Pivotally connected to the eccentric 93 is a dog 99 the end 100 of which is adapted to engage the ratchet teeth of the ratchet 98 and a spring 101 tends normally to move the dog 99 into engagement with the ratchet teeth of the ratchet 98.

the dog 99 is in engagement with the ratchet 98 it.will be mani Asa means forlocking the carrier 16-18 As the shaft 13 rotates and assuming that" est that the slides 95 with the ejectors 91 will be reciprocated.

against advancement during the operation of the ejectois 91,there'is provided abar 102 which moves in asuitable guide 103, the end 104. of the rod being disposedadjacent the path of movement of the beveled portion 97 of the slide 95 and a-spring 105 tends normally to raise the bar 102. The lower extremity ofthis bar 102 is adapted to be moved into the path of movement of the member 76 so as toprevent the latter from being rocked about its pivot (see also Figure 7) when the member 72 is adjusted by the incoming contalners or receptacles. This will prevent the I bar or member 81from being shifted lateral- "ly and thereby the shoulder or formation permitting the latter to be moved under the influence of the spring 77 about its pivot 74 so that the shoulder or formation 83 will be moved into the path of movement of the end 90 of the arm 88 to permit the dog 86 to be released so that motion will be imparted to the carrier 1618. a

Shouldfor any reason the members 72 and 73 be shifted while themember 76 is locked against movement by the bar or rod 102 it will be manifest that the member 73 will be moved independently of the member 76 and against the stress of the spring .77, thereby preventing injury to the machine.

The dog 99 is controlled by means of an arm 106 (see Figure 3) pivotally mounted at one end as at 107 and pivotally connected at its other end as at 108 with a bar 109. Tothe latter and by one end is pivotally connected a link 110, the other end of vwhich link is pivjotally connected toan arm 111, the latter being pivotally connected at one end as at 112. Carriedby the end of the arm 111 is a roller 113 which co-operates with a cam 114 connected with the gear 42. A spring 115 is connected by one end with the link 110 and by its other end with the arm or lever 109 and assists in holding up the arm and also the lever 106.

Y On the lever 106 is a shoulder or formation 116 which'is adapted to be moved into the path of movement of the extremity of the dog 99 to rock the latter about its'pivot and cause it to disengage the ratchet 98 to arrest the movement of the ejectors and the slides A latch member 117 is pivotally mounted by one end and its other end 118 is disposed so that a spring 119 will tend normally to move the end 118 against the periphery of the disc and thisend of the latch is provided witha notch or recess 120 into whichf one end 121 of the arm or member 109 is adapted to enter when the roller 113 drops into one of the recesses or cut away portions 122 of the cam 114.

' The extremity 121 of the member 109 will stand in proximity to the periphery of the cam 114 and will also be disposed in close proximity to a cam or formation 123 on the periphery of the disc 45 and which portion 123 is shaped to form a shoulder adapted to engage the end of the member 117.

When the-parts are in the position shown m Figure 3, that is with the end 121 of the arm or member 109 out of contact with the notch or recess 120 in the latch 117 the shoulder or formation 123 on-the disc 45 will have assumed a position to permit the extremity of the latch 117 to pass under the shoulder or formation 123. This will be the position of the parts until the gear 42 has rotated sufiiciently to cause the roller 113 to move over one of the cam portions 114 to a position where it will drop into or enter one of the recesses-or cut away portions 122. Dur-' ing this movement of the roller 113, the carrier 1618 .willhave moved three steps of movement or until it has assumed the position shown in Figure 5. As the roller 113 is traveling over the cam faces 114 the shoulder or formation 116 on the lever 106 will have assumed a position to engage the end of the dog 99 to cause the dog to disengage-the.

ratchet 98 so that the carrier will. not be advanced until the dog 99 is released. As soon as the roller 113 drops into oneof the recesses or cut away portions 122 of the cam 114 the link 111 will be lowered and this 'will,

through the medium of the link 110, rock the arm or lever 109 about its pivot 108 or until the end 121 enters the notch or recess 120-in the extremity of the catch '117. The shoulder 116 on the lever 106 will still be in a position to hold the dog 99 in an inactive position. When the parts are in this position it will be manifest that when the disc 45 is then rotated in the direction indicated by the arrow in Figure 3, the cam or formation 123 will engage behind the end of the catch 117 to shift it about its pivot, which movement will depress or move the arm 109 longitudinally against the stress of the spring 115.

This will rock the lever 106 about its pivot 107 and will move the shoulder or formation 116 out of engagement with the tail of the dog 99 to releasethe latter so that the spring 101will cause the dog 99 'to lock the eccentric 93 with the ratchet 98, with the result that the eccentric 93 will be rotated and the .ejectors 91 will be reciprocated.

As soon as the cam or formation 123 asses out of engagement with the latch 117 t e end 118 of the latch will be moved intocontaot with the periphery of the disc 45 through the vmedium of the spring 119 and the arm or lever 109 will be moved by the passing of the roller 113 out of the recess or notch 122 in the cam 114 thereby positioning the shoulder 116 on the lever106 so that it will engage the tail of the do 99 to trip the latter upon the completion o the cycle of operation of the eccentric 93. y a

As the carrier 1618'is advanced the stop 62 will be positioned to arrest the feeding movement of the containers into the-machine.

In order to set the machine in operation, as has been before stated, the containers 61 (see 6) must engage the member 72 shift a it. If it should so ppen that apredeter mined numbef'of containers is not fed into machine and the machine before the carrier operates, it is desirable that the carrier shall be actuated.,

Therefore by arran the pulley 59 of the endless conveyor 57 ad acent one side of the y arranging the support 60 in alinement with the upper run of the carrier, it will be manifestthatthere will be fed into the machine only the containers which are carried by the endless carrier. Therefore should a'numb'er of containers less than the required or desired number be fed into the machine, the conveyor 57 will deposit the containers upon the support 60 and before the machine will be started to operate by the shifting of the members 72 by the containers,

it is necessary that a predetermined number of containers be su plied so that the foremost container of t e supply shall engage and shift thb member 72. Just before the machine is started into operation and when the stop 64 is in position to arrest the further feeding containers thereon.
