Definitions
- My invention relates to machinery for making cartons or boxes.
- the side walls have flaps which are folded upon the surfaces of the ,end walls.
- Cartons or boxes of this particular character are used for various purposes and are very popular.
- the object of my invention is to provide a machine which will receive the. sheet of cardboard in blank form and fold and staple the same to produce a carton or box of this particular character. It contemplates a machine having a hopper in which the blanks are held, and fro-m which the same are fed automatically to the forming and stapling devices, whereby each blank is automatically folded and then stapled together to provide a carton or box of the desiredshape and character. More broadly considered, it contemplates a machine which will automatically fold and secure the-sheet material together, thereby providing a carton or box having sides and ends extending at right anglesto each other, as Well as at right angles to the bottom, and an integral cover in the'plane of one side wall.

- Fig. 19 shows a box or carton of such form that the flaps do not lap.
- Fig. 20 shows a form of box or carton in which the flaps are inside of the end walls.
- my invention com prises a frame or body A adapted to support the various operative parts in suitably elevated positions.
- the said frame is provided with a horizontal support a upon which rests a reciprocating table B, which latter is provided on its upper surface with teeth I). These teeth are adapted to engage the edges of the blanks to feed them forward.
- the said reciprocating table is operated by a -lever 72 connected therewith by links 6 and having its lower end pivoted at 6
- This lever b is operated by a cam 12* connected therewith by means of a strap 6 which cam is carried on the drive shaft C.
- the hopper D is disposed over the said reciprocating table, and is adapted to receive the blank E, shown in Fig. 15, and shown more clearly by Fig. 5.
- the said blank consists of a bottom 6, side walls 6', end walls 6 and end flaps e e together with a cover a integral with the upper edge of one placed in the hopper, it will be seen that the covers 6 extend forward in the direction in which the blanks are to be fed.
- Each blank when fed forward rides over an inclined stationary member 6, so that the forward edgeof the central portion of each blank is caused to bend slightly upwardly, as shown in Fig. 6.
- This upwardly displaced portion of the blank is then caused to pass under
- Adjustger b which latter projects downwardly very close to the top of the member 6 there being just room for a single blank to pass.
- the folding and forming mechanisms comprise a vertically disposed plunger F, which is rectangular in shape,-
- This plunger has a-link f'that connects it with a strap f which is operated by the cam f I and which has its rear end pivoted at f to the upper end of a link f which latter has its lower end pivoted at f.
- Rotation of the cam f causes the plunger F to move up and down in its housing or bearing 7.
- the said housing carries the upper strippers f which i are adapted to engage the edges of the ends I of the carton, when the latter is finished,
- the lower strippers f serve to engage the lower edge of the cover of the carton, thereby assisting in lifting the same off fI'OIIL-ilhQ plunger.
- the strippers f are joined at the back of the plunger to form a back stripper f which'latter engages the lower edge of the'side of the carton.
- the housing for the plunger is provided with a pivoted finger or knock-out device 7', which latter is normally. pressed against the plunger by a spring f, as shown in Fig. 8.
- a The plunger has a slot or groove 7' onlits face into which the'said finger or knock-out device 7 is adapted to slide when theplunger moves downward.
- said plunger is also provided with cams f j adapted'to engage rolls f on the finger f, whereby the latter is caused to move outwardly when the plunger moves down, as shown in F ig.,9. This throws .the carton out of the machine,as the cover of the carton slides down over the finger 7".
- the plunger is astationary form having downwardly projecting and voutwardly extending folders g at each side thereof. These folders engage the side walls e to fold the same downward when the plunger moves upward.
- the upper portion of said folders g are vertical and parallel, being in the form of side walls,'and slide on'the side of the carton duringthe upward movement of the latter. This sliding action also occurs when the carton moves downward after being formed, as'formerly explained.
- the ends of the blank are fed into channels 9 disposed at opposite ends of the form.
- each channel is slightly depressed, sothat the overhanging portions 9 will cause the end walls 6 of the blank to be depressed considerably below the flaps e 6, which latter will rest upon the shoulders 9
- This member 9 has a vertical stem-or shank -g which is connected with the springs g whereby it is held normally in the position shown in Fig. 4. These springs, however, yield to the pressure of the plunger, so that The said memduring the folding of theblank the 'member g moves upward to permit the folded carton to finally come to rest within the square or rectangular form G, in the manner explained, and with the cover e in the vertical plane of one side wall of the square corner carton thus made.
- the said cover a is preferably disposed at the puter side of the machine, and the folding and other devices are arranged to afford clearance for said cover, thus preventing breakage of the latter and insuring the desired results.
- the wire for the staples is carried on reels I, and the said wire is fed to the two horizontally disposed staplers by means of the automatic feed devices J, which latter are connected for simultaneous operation by a link j, in the manner shown in Fig. 2.
- the said wire feeding mechanisms are operated by means of the rod or link j which extends down? ward to a lever j* as shown in Fig. 3. It will be seen that this lever has its rear end pivoted'at j and is provided with a roll j that engages a cam j on the shaft C.
- the spring j holds the lever normally downward, and when the shaft 'C is rotated the rod y" is reciprocated to operate the wire feeding mechanisms.
- the said staplers are operated by elbow or bell crank levers i which are pivoted on the frame of the machine, and which are connected by rods or pitmen z" with the lever i This lever isv held normally upward by springs 2' (See Figs. 2 and 4.)
- the said lever is pivoted at its rear endat f and has a pin or roll 2" adapted to engage the groove of the cam 11 on the shaft C. (See Fig. 4.)
- rotation of the shaft causes the reciprocation of the rods or pitmen i with the consequent operation of the staplers.
- the staplers drive the staples e through the flaps and end walls of the carton to hold the same in shape.
- I provide a machine for automatically folding and stapling blanks to produce cartons or boxes which are square or rectangular in form, having square corners, the sides and end walls of,each carton or box extending at right angles to each other and at right angles to the bottom, and one side wall having an integral cover which is handled by the'machin'e in a manner to prevent folding thereof during the making of the carton.

Application filed July 1, 1909. Serial No. 505.490.
To all whom it may concern: I Be it known that I, EDWARD CRAIG, a c1t1- zen of the United States of America, and resident of St. Joseph, Berricn county, Michigan, have inventeda certain new and useful Improvement in Automatic Carton- Machines, of which the following is a spec1- fication.
My invention relates to machinery for making cartons or boxes.
It relates more particularly to machinery for making square or rectangular boxes which are each provided .with a folding cover. Cartons or boxes of this kind'are' ordinarily made of paste-board, which material is folded to provide a carton or box having straight sides and ends, a fiat bottom, anda cover flexibly secured to the upperedge of one of the side walls. The side walls have flaps which are folded upon the surfaces of the ,end walls. Cartons or boxes of this particular character are used for various purposes and are very popular.
The object of my invention is to provide a machine which will receive the. sheet of cardboard in blank form and fold and staple the same to produce a carton or box of this particular character. It contemplates a machine having a hopper in which the blanks are held, and fro-m which the same are fed automatically to the forming and stapling devices, whereby each blank is automatically folded and then stapled together to provide a carton or box of the desiredshape and character. More broadly considered, it contemplates a machine which will automatically fold and secure the-sheet material together, thereby providing a carton or box having sides and ends extending at right anglesto each other, as Well as at right angles to the bottom, and an integral cover in the'plane of one side wall. The
1 nature of my invention will, however, hereton from the machine. Fig. 10 is a fragmentary or detail'perspective view of the mechanism for folding the blanks. Fig. 11 is a perspective of one of the strippers for releasing the finished carton from the plunger when the lattermoves downward. Fig. 12 is an enlarged detail sectional view of the reciprocating table and the stationary support upon which the same rests. Figs. 13 and 14. are detail views of certain devices for assisting in the folding of the end walls of the carton. F ig.15 is a perspective of the blank from which the carton is made. Fig. 16 is a perspective of the finished carton. Fig. 17 is a side elevation of the plunger and form shownin Fig. 7. Fig. 18 shows a form of boX or carton requiring two staples for each end. Fig. 19 shows a box or carton of such form that the flaps do not lap. Fig. 20 shows a form of box or carton in which the flaps are inside of the end walls.
As thus illustrated, my invention com prises a frame or body A adapted to support the various operative parts in suitably elevated positions. At itstop the said frame is provided with a horizontal support a upon which rests a reciprocating table B, which latter is provided on its upper surface with teeth I). These teeth are adapted to engage the edges of the blanks to feed them forward. The said reciprocating table is operated by a -lever 72 connected therewith by links 6 and having its lower end pivoted at 6 This lever b is operated by a cam 12* connected therewith by means of a strap 6 which cam is carried on the drive shaft C. The hopper D is disposed over the said reciprocating table, and is adapted to receive the blank E, shown in Fig. 15, and shown more clearly by Fig. 5. The said blank consists of a bottom 6, side walls 6', end walls 6 and end flaps e e together with a cover a integral with the upper edge of one placed in the hopper, it will be seen that the covers 6 extend forward in the direction in which the blanks are to be fed. Each blank when fed forward rides over an inclined stationary member 6, so that the forward edgeof the central portion of each blank is caused to bend slightly upwardly, as shown in Fig. 6. This upwardly displaced portion of the blank is then caused to pass under afinger b, which latter projects downwardly very close to the top of the member 6 there being just room for a single blank to pass. Consequently, if two or more blanks have been accidentally-fed forward by the reciprocating table,.only one blank can then pass between the member I) and the finger 6 as the space between the two will not admit more than one blank. The blank thus fed forward is then seized by a pair of feed rolls 6 which are operated by a sprocket chain connection I)", as shown in Fig. 3. This sprocket chain leads to a sprocket 12 on the shaft 6, which latter has a gear connection Z) with the shaft U, as shown in Fig. 1. In thisway the blanks are automatically fed forward to the forming and stapling mechanisms, which latter are as follows: The folding and forming mechanisms comprise a vertically disposed plunger F, which is rectangular in shape,-
and thereby adapted to fit the interior of the square corner carton. The lower end of this plunger has a-link f'that connects it with a strap f which is operated by the cam f I and which has its rear end pivoted at f to the upper end of a link f which latter has its lower end pivoted at f. Rotation of the cam f causes the plunger F to move up and down in its housing or bearing 7. The said housing carries the upper strippers f which i are adapted to engage the edges of the ends I of the carton, when the latter is finished,
thereby disengaging the finished carton from the plunger. The lower strippers f serve to engage the lower edge of the cover of the carton, thereby assisting in lifting the same off fI'OIIL-ilhQ plunger. The strippers f are joined at the back of the plunger to form a back stripper f which'latter engages the lower edge of the'side of the carton. The housing for the plunger is provided with a pivoted finger or knock-out device 7', which latter is normally. pressed against the plunger by a spring f, as shown in Fig. 8. A The plunger has a slot or groove 7' onlits face into which the'said finger or knock-out device 7 is adapted to slide when theplunger moves downward. The
said plunger is also provided with cams f j adapted'to engage rolls f on the finger f, whereby the latter is caused to move outwardly when the plunger moves down, as shown in F ig.,9. This throws .the carton out of the machine,as the cover of the carton slides down over the finger 7". When the carton is stripped from t e plunger,
of the groove'or slot f, serve to deflect the cover outwardly and over the finger or knock-out device f when the plunger moves downward.
Above the plunger is astationary form having downwardly projecting and voutwardly extending folders g at each side thereof. These folders engage the side walls e to fold the same downward when the plunger moves upward. The upper portion of said folders g are vertical and parallel, being in the form of side walls,'and slide on'the side of the carton duringthe upward movement of the latter. This sliding action also occurs when the carton moves downward after being formed, as'formerly explained. The ends of the blank are fed into channels 9 disposed at opposite ends of the form. It will be seen that the central portion of each channel is slightly depressed, sothat the overhanging portions 9 will cause the end walls 6 of the blank to be depressed considerably below the flaps e 6, which latter will rest upon the shoulders 9 The blanks are fed into these channels g by the feed rolls b and the motion inv this direction form, and which are mounted upon the sta= tionary frame of the machine, serve to' en-.
The motion continu- ,ing,- the folders 9 one at each end of the gage the flaps 6 thus causing these flaps to fold faster than the flaps 6 "In. this way the flaps are folded one overithe other upon the outer surfaces of th eend walls, the flaps 6 always resting inside of the flaps e, as shown in Fig. 16. The folding of the flaps wupon the outer surfaces of the end walls is further insured by theend folders g which are carried by the lower end of the member 9 and which engage the end walls e to fold the same quickly downwardly at right angles to the bottom 6, and the flaps then fold into place on the said end walls. ber g is co-extensive with and bears upon the bottom e, asthe plunger moves upward. This member 9 has a vertical stem-or shank -g which is connected with the springs g whereby it is held normally in the position shown in Fig. 4. These springs, however, yield to the pressure of the plunger, so that The said memduring the folding of theblank the 'member g moves upward to permit the folded carton to finally come to rest within the square or rectangular form G, in the manner explained, and with the cover e in the vertical plane of one side wall of the square corner carton thus made. To obtain the best results, the said cover a is preferably disposed at the puter side of the machine, and the folding and other devices are arranged to afford clearance for said cover, thus preventing breakage of the latter and insuring the desired results. When the blank is thus folded, it is secured, in place by staples e which are inserted through the flaps and end walls of the box. These staples are driven by any ordinary or suitable stapling mechanisms, such, for example, as the staplers H,
which latter involve the usual staple formers and drivers, anvils and loop blISyGlZQ. The wire for the staples is carried on reels I, and the said wire is fed to the two horizontally disposed staplers by means of the automatic feed devices J, which latter are connected for simultaneous operation by a link j, in the manner shown in Fig. 2. The said wire feeding mechanisms are operated by means of the rod or link j which extends down? ward to a lever j* as shown in Fig. 3. It will be seen that this lever has its rear end pivoted'at j and is provided with a roll j that engages a cam j on the shaft C. The spring j holds the lever normally downward, and when the shaft 'C is rotated the rod y" is reciprocated to operate the wire feeding mechanisms. The said staplers are operated by elbow or bell crank levers i which are pivoted on the frame of the machine, and which are connected by rods or pitmen z" with the lever i This lever isv held normally upward by springs 2' (See Figs. 2 and 4.) The said lever is pivoted at its rear endat f and has a pin or roll 2" adapted to engage the groove of the cam 11 on the shaft C. (See Fig. 4.) Thus rotation of the shaft causes the reciprocation of the rods or pitmen i with the consequent operation of the staplers. When actuated, the staplers drive the staples e through the flaps and end walls of the carton to hold the same in shape.
From the foregoing, therefore, it willbe seen that I provide a machine for automatically folding and stapling blanks to produce cartons or boxes which are square or rectangular in form, having square corners, the sides and end walls of,each carton or box extending at right angles to each other and at right angles to the bottom, and one side wall having an integral cover which is handled by the'machin'e in a manner to prevent folding thereof during the making of the carton. The blanks are carried in superimposed condition in the hopper, and are automatically fed one by one from the bot tom thereof, and with the cover 6? in advance, to the forming or foldingmechanism. Each blank is then automatically folded tightly upon the square or rectangular plun-- ger, by the folding'devices described, and a single staple is then inserted in each end of the carton or box to hold the same in shape. The folding of a blank to provide a carton of this form having square corners and an integral cover involves many difiiculties and problems heretofore not encountered in the production of receptacles, but
by my invention these are overcome and solved in a practical manner.
' For the broader purposes of my invention,
do not limit myself to the exact construe tion shown and described, or to the production' of cartons-or boxes of the exact shape and form illustrated herein. If desired, the same maybe of the form shown in Fig. 18, which requires two staples, for each end of the box. In Fig. 19 the flaps are outside, butfdo not lap. In Fig. 20 the flaps are inside. Obviously, the machine can be constructed for making these or other cartons without departing from the spirit of my invention. Also, the drawings show the illustrative machine in such position that the plunger 1" moves upward to make the carton; but this may be changed or modified to suit the circumstances and requirements of other cases, and, for the broader purposes of my invention, .it will be understood that carton, automatic forming devices having means for folding the end flaps upon the ends, to form therewith the end walls of the,
