MACHINE FOR MAKING RECEPTACLES. 1

Specification of Letters Patent. Patented Sept. 29, 1914.

. Application filed. JuneBO, 1913. Serial No. 776,546.

To all whom it may concern i i Be it known that 'I, Josnrn WEs'roN Corina, a subject of the King of Great Britain, residing at 50 Burgoyne road, Harringay, London, England, have invented new and useful Improvements in Machines for Making Receptacles, of which the following is a specification. f

My invention relates to folding and gum ming mechanism for use in machines for the manufacture of cartons, paper boxes, bags and the like, the invention being specially applicable to machines of the kind.

described in the specification of my former application Serial No. 7 57 997 providedfwith two sets of folding and gumming mechanism to which the sheets of material to be folded are fed alternately by a single feed mechanism, but also applicable for use in machines where the feed. isotherwiseeffc-cted, the chief object'of my invention being to provide a folding and gumming mechanism which shall operate in such a manner that a powder-proof box, carton or the like shall be obtained. The improved mechanism comprises a plunger which reciprocates vertically in a forming slot or channel beneath it, the said slot having arranged in conjunction with it combined folding and gumming rollers carried by a bell-crank lever which isoperated in such a manner as to cause the rollers to partially fold the blank, on one side of the plunger and apply gum, the final folding being effected by fixed fingers and. hinged leaves arranged adjacent to the folding channel. Spring devices are also arranged in conjunction with the folding channel for retaining the folded carton when the plunger again rises, and: also for pushing in the sides of the folded carton when removed from the plunger so as to prevent the next formed carton from being telescoped into it.

To enable my invention to be fully understood, I will describe the same by reference to the accompanying drawings, 1 in which i 1 Figure 1 is a front view of so much of a box or carton making machine as is neck essary to illustrate my invention. 2 is aplan, and Fig. 3 an end view of the same. F1g. 4 1s a vertical sectlon on the line 4, 4, Fig. 1. Fig. 5 is a horizontal sec-s tion on the line 5, 5, Fig. 1, showing apart of the folding mechanism. Fig. 6 1s. a .sec-

surfaces.

tional plan of a part of the gumming mechanism, Figs. 7, 8 and 9 are perspective views illustrating differentv stages of the operation of the gumming and folding a carton. Fig. 10 is a perspective View of a finished carton. Figs. 11 and 12 areviews of opposite sides of a folded carton opened out inorder to show the position. of the folds and the positions in which the gum is ap )lied. Figs. I13 and 1 are views similar to *igs. 1 and 3 illustrating a modification.

j 67 indicates one end of the frame of amachine of the kind described in the specification o-f mysaid former application Serial No. 7 57997 and b the table on to which the blanks to form the cartons or the like are fed, say through the medium of feed rollers 0 0., 1 1

cl is the plunger'which effects the partial forming or folding and'e the forming channel arranged beneath a slot in the table projects over the folding channel 6, as

clearly shown in Figs, 1 and 2.

z, z are the folding rollers and '5 i are flanges formed upon the said rollers and the peripheries of which form the gumming These rollers are carried by the arms j, y' of a bell-crank lever formed in duplicate and freely pivoted on a shaft j, the said levers having theirarms 1' connected by a tie-rod j so as to compel them to move in unison against the tension of a spring 7' It will be understood that these duplicate bell-crank levers are mounted in such relation to one another that the distance between the opposed faces of theroll- ,ers cl, 2' which they carry will correspond of a rod Yrin such a manner that, when the projecting end or nose of the said trip-lever la is acted upon by the plunger cl, it will be pushed down by the said plunger and cause the bell-crank lever to rock upon its aXis in order to bring therollers i, from the positio'n shown iii-full lines in F i 1 to that indicated by the dotted lines in the said figure. e

w thesides of the channel 6 adjacent to mere-11er 2' arearranged the linger-pieces Z whichtooperate with the said rollers to form the: tricks in the bottom of the box, as hereinafter described, and below these finger-pieces again are arranged hinged leaves orplatesm which, when the plunger has reaeh'ed a certain point close against the latter: to fold in certain of the flaps on the carton; These leaves are arranged in conjuries-0a with springs which tend to close them against the. plunger and are pulled away from the plunger at the desired moni'e'nt by means of a earn a on the shaft of machine. from which the plunger is refc'1' "roc'ated, but which is not described or ii ust'r'ated in thepresent specification as it forms no part of the present invention. The .rnotion of, this cam is transmitted to the leaves through the medium of a lever n and a 'iec" a of the well known Bowden wire, which is attached to a block a having flexible connection a a connected to the leaves. Where two sets of folding mecha nism'are'em'ployed as described in my said [former appucation Serial No. 757,997, another lever a? and wire a indicated by dotted lines in Fig. 1, are employed in conjunct'ion' withvthe earn a to operate the plates m of the additional folding mechanism.

o, of aregui'n font rollers which are attached to the shaft y' and the peripheries of which are grooved so that the gumming portions 2, i of the rollers i, 2' can run in them; these font rollers can be rotated by any suitable means, for instance, through the medium of a chain 10 running upon a sprocket-wheel 9 ,011 one of the shafts of the machine, which is alternately driven in opposite directions and synchronises with the up and down movement of the plunger d. v The chain 79 also passes around a sprocket wheel 7 on the shaft y' Either of the wheelsp 79 is arranged as a free wheel, that is to say, it only drives in one direction and runs free in the other direction the shaft 7' being rotated in the downward movement theplunger d. The gum is supplied to the font rollers "0, o from fonts Q in the forin of boxe arranged in rubbing contact with" the peripheries of the wheel 0, c, gum being supplied to these boxes from a tank through pipes such as 9 V, In the operation of the machine the blank is fedon to the table 7) and brought to rest with itscen'ter' beneath the plunger d so that,

as the latter descends, the two ends of the blank will turn upward against the faces of the said plunger, as shown in Fig. 7 to form two flaps 0, 1. As the plunger d moves downward the lower parts of the front flap 1", come into contact with the gumming surfaces 2' so that gum is applied as indicated at 8, s, Fig. 7 to those parts of the flap to which the tucks hereinafter described formed at the bottom of the boX are to be caused to adhere. The plunger having reached this position comes into contact with the projecting nose of the lever and thereby oscillates the duplex bell=crank lever j, j so that the folding rollers 2' come into contact with the lateral portions of the front flap a" and turn them inward in contact with the sides of the said plunger, as shown in Fig. 8, the bottom tucks 2', being at the same time partially formed, and the gumming surfaces 6 2' brought into contact with the lateral portions of the back flap 7' while at the same time a little gum is applied on to the partially folded tucks, as indicated at 8 As during, the downward movement the par tially folded tucks t, come into contact with the fingers Z, Z they are turned upward against the gummed portions 8, s as shown in Fig. 9'; The downward movement of the plunger d continuing the lateral portions of of the back flap 1 on to the previously folded lateral portions of the front flap r to com plete the folding operation and to produce a box or carton of the shape shown in Fig. 10. Figs. 11 and 12 show clearly the folds indicated by dotted lines, which are put into the blank during the folding operation and the positions in which the gum is applied. As the plunger (Z reaches its extreme downward position, blade springs u arranged on the plates 9', 9 pass above the edges of the folded box into contact with the plunger, so that, as the plunger moves upward, they prevent the said box from moving with it. As the plunger leaves the carton or box other blade springs '0, which were pressed into recesses in the plates g, g by the downward movements of the plunger, spring inward and slightly push in the sides of the saidfc'arton or boX, as indicated by the dot-- ted lines in Fig. 10, so that when the bottom of the nekt folded carton comes into contact with it, the' latter will be forced downward in the channel 6 without its being entered by the said neiit folded carton.

In the foregoing description I have re at the points 8, 8, this being effected by the said table. Without the use of this tilting table the weight of the projecting portion of the flap 1" abovethe table might have theeffect of bending the paper so as to keep the,

portions of the flap upon which the gum should be applied at s, 8 out of contact with the roller gumming surfaces 2' at the re quired moment. The table it is provided with a spring 72, to maintainit in its normal position as shown.

w, w are bars arranged at the sides of the lower part of the channel 6 and designed to be heated in any suitable manner so as to dry the gum on the cartons as they are fed ,downward in thesaid channel.

As in some cases the projection of the nose of the lever for rocking the duplex lever might be objectionable I may modify the arrangement of this lever, that is to say, instead of causing it to project into the channel 6 in which the folding is effected I may arrange it outside the channel, as

shown in Figs. 13 and 1 1, and provide a supplementary plunger al for making contact with the said lever, this supplementary plunger operating in the manner hereinbefore indicated at the required moment. As the spring j in connection with the lever is in this arrangement is connected to the frame a instead of to a part of the gum font support as in Figs. 1, 2 and 3 the fonts 0.

may be connected by a cross channel.
