Specification of Letters Patent.

Patented Oct. 29, 1918..

- Application filed May 3, 1913. Serial No. 765,382.

To all whom z't may concern."

Be it known that I, ALFRED GODFREY, of

the city of London, in the county of London, England, engineer, have invented a certain new and useful Packaging-Machine, of which the following is a specification.

This invention relates to the manufacture of cases in paper, cardboard or other similar material and the packing of cigarettes and like goods therein. According to the invention the paper or cardboard blank can be fed into the machine to a registered position, 1s held firmly and cut to the desired shape, the proper number of cigarettes or other articles are fed automatically from a hopper onto the cut and creased blank, the dust from the cigarettes is conveyed away from the work ing parts, the consolidation of the o1garettes as a compact series is effected, the blank is folded at various parts with sharp corners at the various edges into the form of a case, certain parts receive a coating of gum or other agglutinant at the necessary edges from adjustable mechanism arranged to deliver strained gum or other agglutinant to the surfaces, the parts folded down are pressed down into contact so that they adhere and are mechanically fed into a contractible drying chamber for final drying to make a secure passage and finally the case containing the cigarettes is automatically discharged from the machine in a complete condition ready for sale.

In order that my invention may be better understood, I will-now proceed to describe the same in relation to the accompanying drawings, reference being had to the letters and figures marked thereon. Like letters re-. fer to like parts in the various figures.

To carry my invention into effect I arrange a feed table a on which the sheets of paper or cardboard can be fed by hand and in connection with such table I arrange advancing and retiring fingers b which have a reciprocating motion given to them by a cam b" operating the bell crank 6 connected by means of a forked end 6 with a pin 6 carried by a slide 6 to which the fingers b are rigidly attached; the motion of the bell crank 12 in the opposite direction to that given it by the cam b is effected by a spring 6 The ends of the fingers b are adapted to engage with the edge of the paper or, cardboard lying on the table a and feed it for-' ward to a position of definite register and to retire again to engage the next piece of paper as the machine moves.

The paper blank, which may have been cut and creased in any suitable manner (not shown), is seized by gripping means consisting of a slide d adapted to reciprocate on the bed of the machine and having at one end pivoted grippers cl, the end (Zof which holds the paper tightly upon the upper surface of the slide (l. The slide (2 is reciprocated along the bed by means of a pivotedhas a lateral extension d which contacts during the reciprocating movement witlr a spring pressed pivoted switching arm (Z so that on the forward movement the projection 03* engages on the under inclined face of the arm d, until nearing the end of the reciprocating stroke the extension (l trips past the lower endof the inclined surface so as to allow the spring pressed plunger (Z to force the grippers into contact with the paper. On the return stroke, the extension (2 rides,over the upper inclined surface of the arm al which being spring pressed is forced in a downward direction against such spring and thus allows the extension (Z to pass freely over it and when the said extension has passed the arm d the latter rises again under the action of its spring into position ready for the next forward stroke. The arm al is prevented from an upward movement above the position shown in Fig. 4 by a fixed stop d against which it abuts.

As the grippers d reach the right hand end of their stroke so that the cut blank is disposed over the folding die a the lateral extension 03 is disposed under a pivoted arm 03 operated by a connecting rod d, pivoted lever (Z and cam cl so as to raise the end d of the grippers d from the paper and release it. In order to take up the momentum of the slide cl at the end of the backward stroke a spring buffer d" is arranged in the frame shown on an enlarged scale in Fig. 1*. On each side of the machine is arranged a cigarette hopper 7 having at its discharge end a reciprocating tray f divided into spaces by parallel ribs P so as to allow a proper number of cigarettes in regular order and in not less than two superposed layers, as shown in Fig. 5*, to be received from the hopper. The side wall of the hopper farthest from the fingers f is cut away sufliciently to allow only one row of cigarettes to be pushed out of the hopper by the fingers. This tray f is reciprocated to and fro during a certain period of operation of the ma chine by means of a pivoted lever f and cam one segment of the cam being provided with an undulating surface f for shaking the cigarettes down and preventing any jamming thereof, and another segmental portion i of circular periphery to maintain the tray 7 stationary during the feeding of the cigarettes from the tray on to the paper blank.

In order to avoid any inconvenience from the presence of tobacco dust shaken out from the cigarettes, in the process of being fed down on to the tray f, inclined chutes 7" are provided at each side of the bed 1 (Fig. 5 on which the tray f reciprocates and another inclined chute f common'to the two chutes f leads the dust away to a safe point of discharge.

This feeding operation is effected by means of a series of fingers 7 correspondingly disposed to the spaces in the tray, the said fingers being moved to and fro by means of forked rocking levers f connecting rod f and a cam f the'return stroke being effected by a spring f shuttingjagainst a fixed stop f carried on the frame of themachine. The levers f and connecting rod f are shown in full and dotted position in Fig. 5 indicating the extent of the motion.

The cigarettes when fed on to the cut blank have to pass between two edges forming a funnel shaped passage by which the cigarettes are closed up one against the other into a width which is less than that occupied by them when on the tray f. The

mechanism is shown in Fig. 5 and the cigarettes assume-the position on the cut blank as indicated in Fig. 5.

The device upon which the blank rests during the preceding operation consists of a rising and falli n table 6' mounted on a parallel link 6 t e pivots e of which are mounted on the frame of the machine, the

.upper pivot e (Fig. 4) being journaled in a sliding block e on each side of the upper member e and adapted to be supported in parallel guides a" mounted on the frame of the machine. The object of its arrangement is to allow the table 6 to only have a vertical motion, the effect of the radial motion of the upper member 6 being neutralized by the sliding of the blocks 6 in their guides e a ainst the ressure of a s rin e behind each block e. As it is important that the level of the table 9' should register to a defi nite position at the bottom of the stroke, adjustable stops a are arranged on the frame for the table to rest on, Figs. 4, 8 and 9. These parallel links are ,operated'by a roller 6 contacting with a cam e". Immediately over the table 6 is a reciprocating plunger e mounted on the frame of the machine by means of a-ntifriction rollers 6. This plunger is adapted to be lifted by a pivoted arm e lever 0, connecting rod 6., pivoted lever e and roller which latter contacts with, the cam 6 The plunger 6 has at-its'lower end a spring pressed projection 0 having an etfective'depth after compressing the spring substantially the same as the depth of the cigarettes, and in addition there is arranged on each side of the plunger 6 pieces e (Fig. 5 which have a depending curved portion 0 so arranged that the end, cigarettes of each layer are restrained from rolling outward on the descent of the plunger 6 It must be understood that the lower surface of theprojection e first contacts with center portion 6 in the proper blank so as to grip it between the projection 6 and the table 6 and at the sametime to form an abutment on each side against which the cigarettes are pressed by the feeding fingers f, the end surface of the plunger 6 now. presses upon the two layers of cigarettes and drives the blank with the cigarettes in place into the folding die a, the table 6 simultaneously dropping to allow this operation to be effected. In passing down through the folding die 6 the sides of the blank are folded as indicated in Fig. 6 and in this condition the whole gumming operation is effected.

Upon the upper portion of the frame of the machine a gum reservoir 9 is disposed the side of which toward the plunger 6 1s open and is closed up by a constantly rotating roller 9 which runs in the direction of the arrow.

In order to prevent any dust collected by roller 9' from getting into the reservoir. 9 a strainer g of wire gauze is disposed across the reservoir 9 and a knife 5 is arranged at the edge of the gauze so as to contact with the peripheryof the roller 9 in order to scrape off the gum and dust therefrom and deliver it on to the top of the gauze for straining it. In Fig. 11 is shown an adj usting arrangement, for the relative position of the gumming roller 9 and plunger to one another comprising a screw 9 passing through a lug g fastened to the frame the said screw bearing against the reservoir 7 and alocking screw 9 passing through the V reservoir 9 and screwing into the center of the screw 9 so as to lock the same firmly against rotation and tightly against the reservoir 9. v

In the lower part of the gum reservoir is a gum throttle g rotatably mounted 1n the ends of the reservoir and means for ad justment by hand are provided so .that the space between the gum throttle and the roller 9 can be adjusted as desired to give a proper thickness of gum layer upon the periphery ofthe roller 9. When no gum is required the throttle can be turned into the position indicated in Fig. 11 under which condition practically no gum is carried by the roller g from the reservoir. The roller 9' is driven by a pulley 9 through gearing g and is bperated by a belt 7 upon the pulley g on the first motion shaft on of the machine. 5

Upon the plunger e a gummin frame is pivoted at 9 having a series of gumming ings g and at its lower end carries an armhaving a roller 9 engaging with a cam 9 The roller 9 is maintained in contact with the cam 9 by means of a spring pressed plunger 9 engaging with a lever g which latter is rigidly fixed to the shaft 9, the position of the lever g. on which 20 the operative function of the gumming mechanism depends is regulated by means of a rod 9 sliding in the frame of the machine and having an inclined surface 9 which when the rod 9 is pushed into its 25 upper position by thestriking treadle g forces the lever g in the direction of the arrow (see Fig. 11) against the spring plunger 9 draws the roller g? away from the cam g" and withdraws the pads 9 into so a non-operative position.

As the plunger 6 ascends, the gumming pads 9 contact with the gumming roller 9' and pick up a regulated amount of gum therefrom and on the descent when the pads v 9* have reached their lowest position the recess 9 in the cam 9" allows the pads to advance toward the flaps of the case and to apply gum thereto as indicated at g in Fig. 6*. A bridge piece 2" mounted on the frame-forms a support for the-paper against the pressure of the gummingpads 9 As the recess 9 moves farther on in the rotation ofthe cam the pads g recede from the said flaps of the case and the further folding operations are then proceeded with.

As the slide 01 travels along on the forward stroke any tobacco dust which has I fallen on the slide bed is pushed by the side d toward the table 6' and would \interfere .jo with its working unless diverted. To effect this an apron e is arranged around the table 6 having an upstanding fence e on three sides as shown in Figs. 11 and 11. on the side where the gumming pads g are dis- 55 posed apertures e are arranged through,

k which the pads 9"- can pass. The dust collects on the surfaces 6 and is pushed along by the front of'the slide d until it reaches v the ldust chutes a? which convey the. dust away from the gumming mechanism.

The flaps h are folded down by means of a device It which consists of pivoted fingers k mounted on reciprocating carriages h, the fingers b belng rocked about an axis by means of a rod k, levers h, mounted on a cam It, the forked levers it being simultaneously operated by quadrant gear h the operative motion of the lever 72, being made against spring pressure from a spring it through a lever k rigidly attached to or forming part of one of the quadrants h so that the return. motion is effected by the v spring k.

Now dealing with the case as shown in Fig. 6 the fin ers k are first rotated so as to fold the rettes as shown in Fig. 6 by the action of the cam h The carriages k .are now moved laterally by means of the cam in so. that the fingers h on their outward lateral motion press upon, the flaps h and produce a sharp corner against an upstanding wall k by means of a slight projection h" on the fingers h", the rods It preventing the fingers h rising until the carriage h has completed its outward motion, and in order to further insure the paper being folded down with a square corner supporting stems 72, are arranged on the wall it so that their operative faces stand vertically so as to support the paper and prevent it from being dragged backward when the fingersk are moved backward 0n the carriage h-'. In addition to the stems 72 a horizontal surface or table It is provided on-the frame in a' fixed position which co-acts with the tail end It so as to maintain the folder h in a horizontal position pressing the flap h downward and holding it there firmly while the carriage it is being retired. When .the carriage k is in its forward position the tail end k of the folding fingers k clears the table 72 thus enabling the tail end h to drop and the folders k to be raised. It must be understood that the plunger e is of less width than the double packet so as to enable the flapsh to be folded down without contact therewithu As the carriages k commence their outward motion the pluner .9 begins to rise so as to leave room fo t e flaps i to be folded down.

aps 71. down upon the ciga The slide (2 carrying the grippers is ,pro- 4 with a folding flap i pivoted at 2' on the frame of the machine and spring pressed to normally maintain a vertical position. As the flap i is turned over it folds down the flap 5 on the cigarettes. As the plunger 71- 'vided with a pushing plunger 71 situated at advances the face of the end 71 comes into contact with the side of the case and pushes it into a channel 71 under the bridge piece 2',

- attachment to the top flap i mes es the top i of the case is folded down on to the cigarettes but notsufliciently closely to cause the gumme d portions 9" to come in contact with and adhere to the flaps a and h. To efl'ect thispurpose the channel 6 is provided with a movable. roof i pivoted at 2' on the frame of the machine and adapted to be oscillated in a vertical direction by means of the lever i roller i and cam i At the end of the movable roof 71 de-.

pending fingers ifare provided, which durclose thepacket first engage the top edge of the flap i in the angular corner i so as to square up the position of the end with its flap '5 for proper In order to register the position of the cigarettes within the two cases so that the final folding pin i 'eof which operation can be effected without disturbing the cigarettes, a regulating rib or finger 2' is fixedly carried on the frame of the machine and is provided with spring tongues 71 normally convergent to one an- 4 other so as to cause an easy entry between the two layers of cigarettes as they are fed along the partially formed packet. Just at the moment of the packet completing this stage of its passage an angular nose 5 mounted'on the slide i enters between the spring tongues i and'forces them into a parallel position in worder to force the cigarettes outwardly against the outer sides of the case and at the same time 'forcethe outer sides of the case against the walls of the channel 11 so as to register their position before the final attaching step of the roof z' is completed. As each packet is completed to this stage, it forces along the'channel i the packets pleted. The form of the packet as now made is represented in Fig. 9. As each packet arrives in turn over an orifice 7c. in the'be'd of the channel i as shown in Fig.

10 iand is ,thus being deprived of any central support it drops down fo'rm'1n full lines to a V shape as shown from its extended in dotted lines.

a modified arrangement 1s .shown for dealingwith the folding down of the flap 2' ready for the flap i to be foldedthereon and the provision of mechanlcal means for feeding the closed "packets along after the folding operations have been completed.- In this thepivoted folding flap 2' is operated by an arm 2' the pivotally engages a block 2' adapted to slide in a slot 2' of a lever i pivoted on the cam stay 0 The other end ofdhelever 2' is coupled to a bridle rod 2' lo y"-means of a connecting rod 5 having'a' roller 2' which co-acts with a cam 2'. On theside of the frame of the macase and register the which were previously com-.

chine is pivotally mounted at the point 5 a slide frame 2' in which slides a pusher 2' having upstanding fingers 2'. The pusher 5 is operated by a connecting rod 2', pivoted lever i roller 2' and cam i the return stroke being effected by a spring 2' The slide frame 2' has a depending arm 2' fixedly attached thereto, said arm having a roller t' co-acting with the cam i and kept into engagement therewith by a spring 91 The pusher 2 as shown in Fig. 6 has just completed the pushing stroke on one packet and is about to retire to get behind the following packet. To do this the cam 2' tilts the frame 2' so as to lower the fingers 2' and allow them to retire under the succeeding packet and then rise again at the back thereof. The sequence of folding down the flap i pushing the packet along and depressing and retiring the fingers i is clearly shown by the relative positions of the cams 2 ,71 and i On the left hand side of Fig. 10 a'reciprocating plunger is disposed in a transverse channel lc and is actuated by a forked pivoted lever 70 roller is, and cam k On 'right hand side of the channel 70 is the drying chamber is.

Inorder to insure that the packet is prop erly folded and located in the proper posi tion in the channel i a modified arrangement is shown in Fig. 10 in which a supplemental folding flap k is pivoted on the frame and is operated by a spring pressed rod 70 pivoted lever is, roller 70 and cam is on the shaft m This flap it falls into the dotted position and bends the packet down to position shown in Fig. 10", ready for being pressed into the drying chamber 70 In this case the flap 7c has a projection la which passes through a slot k in the frame and controls it without the use of the stop h, (Fig. 10). The drying chamber 70 is formed with the top is and one side. k" pivoted to the main part of the ,chamber 70 as to be opened at each step for the packet to enter and to close on said packet so as to facilitate the entrance of 76 This movement is effected by a cam/: on the shaft m? which operates a roller [0 pivoted lever 70 and plunger 7:: which latter has a beveled end adapted to engage a roller 70 so as to move the side is" inwardly. The top k is o erated by an arm k rigidly carried by t e side 70" said arm having a beveled end is co-acting with a roller k pivoted on the top 70 When the plunger 70 is forced'up it closes the side is" which in turn forces the top k downf Both the side 70 and side k" are spring pressed outward so that when the plunger It -retires they revert to the open position automatically so that the packets pass along without any friction or obstruction. In or der to prevent the last packet fed into the dry chamber 70 from falling backward on Y It carries the inclined-surface 6 for working the stops 6 and grippers I) as hereinbefore described.

The packets being fed along the chamber [a under considerable pressure from the flap 70 they would unless restrained fall down at the delivery end when the side is" is opened, in order to avoid this a regulatable flat spring is is fitted to the ins de of the side 7: as shown in Fig. 10 which will hold the series of packets in position until forced past the end thereof so as to be delivered from the chamber.

In an automatic machine of this description it is necessary to prevent contact of the gum pad 9 with parts of the machine during the absence of paper therein and also to prevent the delivery of cigarettes on to the feeding platform 0 in the absence of paper thereon. Shoultl this occur the whole of the integrity of the operations is destroyed and in addition parts "or the machine which should be perfectly free from gum would become coated with gum and consequently the next packet dealt with by the machine would become stuck therein rendering the stoppage of the machine necessary to clear away all-the obstructing material, the removal from the surface of the mechanism of all the gum which has been improperly applied thereto and all the loose cigarettes which had been improperly fed on to the feeding platform.

In order to avoid these serlous inconveniences I provide in the slide d a recess Z 1n conjunction with which is arranged a projecting nose Z carried at the end of a pivoted lever Z to which is connected an upwardly disposed lever i the end of which 1s is adapted to contact with a projection Z on the gumming frame 9 solas to prevent the gumming frame g from rocking 1nto 1ts operative position. i

In order to insure the withdrawal of the projecting nose I from the recess Z before the movement of the slide d, I provide an angular surface Z on the gumming frame 9 which contacts on its upward stroke with a roller Z on'the lever Z and positively withdraws the projectin nose Z from engagement with the slide To prevent the feeding of the cigarettes another arm Z is attached to the lever Z which under normal conditionslies on a recess Z of the feeding meawa finger 1" but inthe eventof the nose'l entering the recess Z the arm Z is raised so as to liein the path of the slide f and prevent the feeding movement taking placeunder the action of the spring f. When the paper is present on the surfaces of the slide (Z the nose Z cannot enter the recess Z and consequently the normal operation of the machine can take place.

In order to remove any old dry gum from the gumming pad 9 which may have accumulated during the stoppage of the machine and which it is necessary to get rid of before the operations are restarted I provide upon the gum throttle g a scraper or knife 9 adapted to come intothe path of the gumming pad g during its reciprocating motion and to'remove the dry gum therefrom and when this has'been effected and the gum throttle g is again adjusted for working purposes, the scraper 9 is automatically removed from the path of the gumming pad 9". To avoid the dry gum from dropping into the machine and becoming an obstruction, I provide a receptacle 9' with catching lips 9 to receive the scrapings of partly dried gum, which receptacle can be emptied of its contents at any convenient time.

It is found to be-desirable to provide simple means for finely adjusting the various parts of the mechanism so as to get the desired pressure and registration of position.

To adjust the cam rollers the journal 0 (Fig. 10 is made eccentric to the part 0 supported in its lever so that it can be moved about its axis and vary the position of the journal 0 relative to mechanism that it is operating. To take up thewear on the prominent part of the cams a method is shown in Fig. 6 comprising an adjustable sliding block 0 arranged at the desired part and held by a screw 0 while an adjusting adjustable limit stop is provided against which the reciprocating part can abut to give a positive terminal position or ,prevent over running of the parts due to momentum.

Motion is transmitted from any convenient source of power to a clutch pulley m by which the shaft m forming the first motion shaft of, the machine is driven; The second motion shaft m is operated by means of spur gearing m? from the shaft m. The cam 0 die 5 13 f4 fio 17 he hi2 :13 2'", i 2' and k are all rigidly mounted upon the shaftm The clutch of the pulley m is operated by' eans of the foot treadle 9 through the mechanism m".

So far as the description has gone th case referred to has been of a double charmemes actor as illustrated in Fig. 10 I will now describe a single case as illustrated in Fig. 12 and the modification in the mechanism that is necessary in order to carry out the necessary operations. 4

The cut blank is illustrated in Fig. 12 and is delivered on to' thetable e in precisely a similar manner to the blank of the double packet already described. The descent of the plunger e folds the blank as illustrated in Fig. 12 with the cigarettes therein. The gumming operation now takes place as previously described. I

It will be noticed that in this single case, corner pieces at are left on one side in order to stiffen the case. The next operation is the partially folding in of the corner pieces n and the complete folding down of the flap n. This is effected by means of a reciprocating slide n having angular projections nfwhich is moved in a direction transverse with the travel of the case along the channel 2' by means of a lever a, shaft '11,, lever n roller n and cam u The flap n is folded down by means of an oscillating finger n slidingly carried on an arm n and spring pressed by a spring 11 the arm n is oscillated by a forked lever n engaging with a pin n of a lever n mounted rigidly on the shaft "a The return motion of the slide n and finger n is effected by a spring at and lever n rigidly mounted on the shaft In order to complete the folding down of the rearmost flap n, a projecting finger 0 is arranged on the forward end of one of the parts 2' of the plunger 71 which contacts with and folds in the side piece a before the case is moved along by the plunger z". The forward corner piece n is folded down automatically as the case is pushed into the channel 2'. The flap p is folded down simultaneously with the final folding of the rearmost corner in a similar manner to that described for the double packet; and as the case is fed along the channel 2', the top flap p is similarly folded down as before described into the position shown in Fig. 12 The portions of the flap p with the requisite gum are represented by p in Figs. 12, 12, and 12 the squaring and consolidating of this single case being efiectedby the same mechanism as in the double packet.

In order to turn up the flap p a helical surface 0 is disposed at the side of the channel 2' so that as the case moves along the channel the flap is moved from a horizontal position into a vertical position as shown in Fig. 12. The only further step to be performed is the folding down of the flap p which is efiected by means of a knife edge 72 in conjunction with another helical surface p which turns the flap p from a horizontal position into an angular position until the casemoves along a further distance opposite a reciprocating slide 39' operated by a lever p rigidly attached to the shaft n". The edge of this slide p squares the top corner edge of the case, after which the case is moved along a further step for the final closing operation. During the passage of the flap 79 along the helical surface, provision is made by means of grooves, ribs, or other convenient arrangements to prevent the gummed portions of the flap 79 from coming into contact with parts of the machine so that when the case arrives at its final stage the gummed parts are intact. The final closure is effected by means of a pivoted device g forming parts of the said walls of the channel i when in the closing position in which it receives the case, the surface of the device 9 forms a continuation of the helical surface p as shown in the drawing. The

movement of the device 9 is effected simultaneously with and by being connected to the slide p through the connecting rod 9 attached to the lower part of the device 9 the upper part of the device 9 being pivoted to an arm 9 rigidly attached to the frame of the machine. The case when completed can if necessary pass into a drying chamber in order to thoroughly dry the gum before final delivery from the machine.

In order that an audible indication can be given to the operator in the event of the packets not coming out properly from the flap closing mechanism shown in Fig. 9, the falling roof 6 is adapted to act as the agent for ringing an electric bell or other signal in the event of it not being able to drop when the cam 2' leaves the roller '5 To this end an electric contact 2' is mounted on the lever i (Fig. 9) in such a position to coact with another contact 2' on the connecting rod f of the cigarette pushing finger mechanism as shown in Fig. 5. An electric bell 2' and battery 2' are included in the electric circuit and when everything is running properly no contact is made and the bell is not rung, but immediately the lever 2' fails to drop and to follow the surface of the cam 2' the contact 71 touches the contact i and the bell is rung indicating that I the roof 2' is not falling into its proper position.

As the momentum of the reciprocating parts of the machine is considerable when running at a high speed positive stops are provided to limit the motion at a definite terminal position for each motion.
