To all whom it may concern..-

Be it known that I, RIoHARD SUNDERMAN, a

citizen of the United States, and a resident of Buffalo, in the county of Erie and State of New York, have invented a new and 1m proved Carton Making and Sealing Machine, of which the following is a full, clear, and exact description.

This invention relates to machines for making and sealing cartons, and has special reference to a machine provided with instrumentalities by which flattened carton shells or tubes may be expanded or opened, then formed into a carton by folding and securing flaps at the bottom of the shell or tube, and the cartons finally closed and sealed after they have been filled.

The principal object of the invention is to provide a simple, durable, and easily-controlled machine by which flattened cartonshells will be fed successively from a stock of such shells into the machine, expanded or opened to tubular form, formed into cartons by folding and securing the bottom flaps at the lower ends of each tube, and finally closed, sealed, and discharged from the machine.

A further object of the invention is to provide a machine adapted for the purposes above specified and having mechanism within the machine for carrying the cartons through the machine so constructed that each carton will be brought into position for filling with any material which it is desired to pack in the cartons and will be held stationary for a suflicient time to permit the manual filling thereof before the carton is carried on to the closing and sealing devices.

Still other objects of the invention are to cheapen the cost of machines of the type specifled, to simplify the construction of such machines, and to provide a machine that may be operated at a relatively small expenditure of power.

A machine embodying the various features of the invention is hereinafter described in detail; but it is to be understood that various changes in the form, proportions, and in the mode of assemblage of the elements described may be made without departing from the spirit of the invention, and the actual scope of the invention is defined in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figures 1, 1 and 1 form collectively a plan viewof a machine constructed in accord with the present invention, part of the top of the machine being broken away to disclose the structures below. Figs. 2, 2, and 2 form collectively a view in side elevation of the machine shown in Figs. 1, 1, and 1 parts being broken away to show the operation of the carton-closing devices. Fig. 3 is an enlarged sectional view on the line 3 3 of Fig. 4 of a portion of the structures shown in Fig. 1, disclosing the operation of the devices for expanding or opening the carton-shells. Fig. 4 is a longitudinal sectional view on the line4 4 in Fig. 3, and Fig. 5 is a transverse sectional view on the line 5 5 of Fig. 4.

Referring to the drawings, Gr indicates a long tubular guideway extending throughout the length of the machine, as shown in Figs. 1, 1*, and 1. At one side of the guideway Gr, near its forward end, there is a feed-chute 1 for the stock 2 of flattened carton-shells. The feed-chute 1 is disposed at an oblique angle to the guideway G, and a follower 3 is arranged for sliding movement in the chute 1 under the influence of weights 4, attached to cords 5, which are fastened to lugs 6 at opposite sides of the follower 3. The cords 5 pass over guide-pulleys 7 or other equivalent structures to give the proper direction of movement to the follower 3. At the inner end of the chute 1 a feed-slide 8 is arranged for reciprocatory movement transversely of the chute and is provided with a shoulder 9 of suitable size to engage with a single flattened carton shell or tube and force it into the guideway G when the slide is moved inward. The slide 8 is operated by cranks 10, mounted upon a shaft 11 at one side of the guideway G, and pitmen 12, connecting the cranks 10 with the slide. When a carton is forced into the guideway G by the feed-slide 8, it is immediately engaged by a conveyor or carrier, which propels the carton shell or tube forward through the guideway and causes it to be acted on by the various instrumentalities, which expand or open the carton shell or tube and form the bottom of the carton. This conveyer leaves the carton in position for filling. As shown in Figs. 3 and 4, the carton-shells are moved horizontally into the guideway G, and this guideway is, as shown in Fig. 5, of such structure that all lateral or vertical movement of the cartons therein is prevented and the cartons are caused to pass forward and brought into engagement with the bottom-forming and carton-closing devices. The guideway G is preferably a box of rectangular cross-section, as shown in Fig. 5, and it is provided with inwardly-projecting shelves 13 adjacent to the top, and similar ledges 14 adjacent to the bottom. The narrow spaces left between the shelves 13 and the top of the guideway and between the ledges 14 and the bottomof the guideway aflord passages for the side flaps of the carton, as clearly shown in Fig. 5. The preferred form of conveyer or carrier by which the cartons are moved forward through the guideway is an endless chain 15, running over sprockets 16 and 17 the former being mounted upon'the shaft 11 at the forward end of the guideway and the latter being carried by a shaft 18 near the middle of the guideway. The endless chain is provided at intervals with flights 19, and these flights are spaced at such intervals that one flight passes each sprocket upon each revolution thereof, and consequently a flight enters the guideway G for every reciprocation of the feed-slide 8.

The opening or expanding of the flattened carton-shell within the guideway G is effected by the cooperation with the flights of the conveyer of dogs 20, carried by arms 21, projecting from a vertical shaft 22 at one side of the guideway. The shaft 22 has an arm 23,which is connected by a link 24 with an arm 25, carried by a horizontally-dis posed shaft 26, which extends across the top of the guideway. The shaft 26 is rocked by a link 27, connected at one end with an arm 28 on the shaft and connected at its other end with a bent lever 29 upon a horizontally-disposed shaft 30 at the bottom of the guideway. The lever 29 is connected by a link 31 with an arm 32 upon a spring-actuated shaft 33. The arm 32 also affords support for one end of a shoe 34, the other end of which is carried bya similar arm 35 upon a spring-actuated shaft 36. The shoe 34 has the rear end thereof beveled, as shown in Fig. 2, and it is disposed adjacent to the line of travel of the endless chain 15, the normal position of the shoe being indicated by dot-and-dash lines in Fig. 2. As the chain travels in the direction indicated by the arrows, the flights will be caused to engage succe'ssively with the beveled end of the shoe 34, and the shoe will be depressed thereby, owing to the simultaneous engagement of the flights with the oppositely-arranged guide plate or strip 37, which prevents the flights from being forced upward by the shoe. To insure the proper contact of the flights with the forward ends of the shoe 34 and to prevent sagging of the conveyer-chain, a guide plate or strip 38 is arranged beneath the conveyer-chain just behind the shoe 34. The length of the shoe 34 and its position are such that when the feed-slide 8 forces a carton shell or tube into the guideway the shoe will be depressed to the position shown in Fig. 2, and the dogs 20 will be projected into the guideway and will be held in that position until one of the flights upon the conveyor-chain engages the cartonshell and forces it forward into contact with the dogs, the contact of the forward edge of the flattened shell being insured by small leaf-springs 39, arranged at the opposite side of the guideway. The dogs 20 engage the forward margin of the flattened shells just long enough to insure the expansion of the shells to the tubular form shown in Fig. 3,

and when the shells assume that form the shoe 34 will be released by the passage of the flight over the forward end thereof and will be allowed to rise to its normal position under the influence of the springs 40 upon the shafts 33 and 36 The movement of the shoe will be accompanied by the retraction of the dogs 20, and the forward movement of the carton-shell being no longer prevented by the dogs the shell will advance in the guideway.

The shafts 26 and 30 above mentioned are provided, respectively, with a resilient flapspreader 41 and a flap-folder 42. The flapspreader 41 is bent to present a convex lower surface, while the flap-folder is normally straight. As the shafts 26 and 30 are rocked in opposite directions when the dogs 20 are retracted from the guideway the flap-spreader 41 will move downward into the position shown in dotted lines in Fig. 4 and the folder will move upward to the position indicated by dotted lines in the same figure. The flap-spreader 41 engages the front and rear flaps at the top of the carton-shell and spreads them apart, so that as the carton-shell moves forward in the guide the flaps will pass under the top of the guideway in the spread position. The flapfolder 42 folds the rear flap at the bottom of the carton-shell and holds it in folded position until the forward flap is folded over by contact with the bottom of the guideway and serves to hold the rear flap in folded position. The spreading of the front and rear flaps at the top of the carton-shell and the folding of the front and rear flaps at the bottom of the shell is facilitated by V-shaped projections 43 and 44 at the top and bottom, respectively, of the guideway Gr. These V-shaped projections present inclined and slightlycurved surfaces, which engage the front flaps at the top and bottom of the carton, and the diverging sides of the projections 43 and 44 also act upon the side flaps at the top and bottom of the carton-shell to spread them, so that they will pass easily into the spaces provided therefor between the top and bottom of the guideway and the adjacent shelves 13 and ledges 14. As each carton-shell advances in the guideway one ofthe side flaps receives a coating of paste or glue from a paste or gluing wheel 45, revolving in a receptacle 46 and projecting upward through an opening formed in the bottom of the guideway G at one side IIC vided in the bottom of the guideway and presenting a curved and inclined surface for engagement with the flap to fold the same upon the previously-folded end flaps at the bottom of the carton. After passing the folder 47 the carton-shell reachesasecond gluing-wheel 48, revolving in a receptacle 49 and projecting upward through the bottom of the guideway. This wheel is so positioned that it applies a coat of paste or glue to the other side flap of the carton-shell while spread outward, as shown in Fig. 1. After passing the wheel 48 the shell reaches a stationary folder 50. by

which the side flap coated by the wheel 48 is folded upon the other side flap and secured thereto. By the action of the wheels 45 and 48 and the folders 47 and 50 the formation of the bottom of the carton is completed, and the cartons are then advanced to the filling position indicated in Figs. 1 and 2, in which position they are left by the conveyer-chain 15.

To facilitate the filling of the carton, the top of the guideway G has an opening 51 formed therein, as shown in Fig. 2*, and when the carton-shells are allowed to come to rest they are immediately beneath the opening 51, as shown, and remain in this position for a sufficient length of time for the filling to be accomplished by hand. If preferred, however, the filling may be accomplished by any suitable filling mechanism timed to operate properly in relation to the machine. filling mechanism forms no part of the present invention, the same is not described or illustrated in this application. After each carton has been filled it is carried forward along the guideway G by a conveyer or carrier arranged at the side opposite the conveyer already described and preferably similar in construction to the conveyer already described. In the form of the invention illustrated the secondary conveyer comprises an endless chain 52, traveling over sprockets 53 and 54, which are mounted upon vertical shafts 55 and 56, respectively. The chain 52 is provided with flights 57, so arranged that one flight passes each sprocket at each revolution thereof. The chain 52 is placed upon its supporting-sprockets in such relation to the chain 15 that after a carton is allowed to come to rest, when the flight upon the chain 15 As such v moves forward, the natural elasticity of the top of the carton causing the flap to spring upward into the opening 51 sufficiently to be engaged by the top of the guideway as the carton is moved forward beyond the opening. Before the front flap of the carton is folded, however, the rear flap is folded by an arm 58, carried by the shaft 55 and moving slightly to the rear of each flight 57 upon the chain 52 as it passes around the sprocket 53. The

arm 58 depresses the rear flap to the position shown in dotted lines in Fig. 2 and holds it in this position until the carton has passed partly under the top of the carton beyond the opening 51 and the front flap is folded over upon the rear flap. After the front and rear flaps of the carton have been folded in the manner explained one of the side flaps is caused to pass under a gluing-wheel 59, supplied with glue or paste from a receptacle 60, and is then engaged by a stationary folder 61. The other side flap is then supplied with adhesive from a gluing-wheel 62, supplied from a receptacle 63, and this flap is then folded by a stationary folder 64, thus completing the closing and sealing of the carton. After the carton has been closed and sealed it passes on its way through the guideway G and is allowed to come to rest momen-' tarily at the end thereof, as shown in Fig. l. A moment 'after each carton reaches the end of the guideway Gr it is engaged by an arm 65, projecting radially from a horizontallydisposed Wheel or disk 66 upon ashaft 67, and this arm forces the carton into a dischargechute 68. The cartons successively forced into the chute 68 by the revolving arm 65 fill the chute and are advanced therein step by step at the successive introductions of cartons thereinto. The chute may be of any desired length, and it is desirable that a sufficient length of time be required for the passage of a carton through the chute to insure the setting of the adhesive, by which the flaps at the top and bottom of the carton are secured.

In order to impart movement to the various instrumentalities entering into the construction of the machine, any suitable arrangement of shafts and gearing may be provided; but I have shown, by way of illustration, a simple arrangement of devices for this purpose. A

bearings at one side of the machine and is provided with fast and loose pulleys 71 and 72. Motion is transmitted from the main shaft to a counter-shaft 73 by intermeshing gears 74 and 75, and from the countershaft 73 motion is transmitted through beveled gearing to all of the gluing-wheels. Beveled pinions 76 and 77 on the counter-shaft 73 mesh with beveled pinions 78 and 79 directly connected with the gluing- wheels 45 and 48, respectively. The gluing- wheels 59 and 62 are connected with bevel-pinions 80 and 81, respectively, which are in mesh with pinions lIC .main driving-shaft 70 is mounted in suitable 82 and 83, mounted upon short vertical shafts 8 1 and 85, which bear at their lower ends pinions 86 and 87, which are in mesh with pinions 88 and 89, respectively, upon the counter-shaft 73. Power is transmitted from the main shaft 70 to the shaft 18, from which the conveyer-chain is driven by means of intermeshing bevel-pinions 90 and 91. The conveyer-chain 52 is driven from the shaft 55, to which motion is imparted from the shaft 18 by intermeshing gears 92 and 93, and motion is imparted to the shaft 67, carrying the disk 66, by a train of gearing comprising a gear 9 1 on the shaft 56, a gear 95 on the shaft 67, and an intermediate gear 96.

From the foregoing description and the drawings illustrative thereof it will be observed that the carton-shells are fed successively into the machine in aflattened condition, are immediately expanded into tubular form, and are then carried through the machine in a substantially straight course. In their passage through the machine the successive operations of forming the bottom'of the carton and closing and sealing the carton are performed without arresting the movement of the carton at all, and the only pause in the travel of the carton through the machine takes place between the formation of the bottom and the closing of the carton, this pause being provided to permit the filling of the carton with the material to be packed therein. It will alsobe noticedthat while a dwell in the movement of the carton is provided to permit the filling thereof the devices for carrying the carton throughthe machine are continuously operated, and all the disadvantages inherent in intermittently-operating carriersorconveyers are overcome. It will also be observed thatthe construction of the machine is such that the operations of the various elements may be positively timed to occur in proper relation, so insuring the satisfactory performance by the machine of every part of its work.

The construction of the machine as a whole is characterized by unusual simplicity, and the parts are of such character and are so as sembled that any derangement of the machine from use is comparatively infrequent, and when any portion of the machine becomes inoperative from any reason it may be readily removed and. replaced.
