Specificationof Letters Patent.

Patented July 31 9 To all whom it may concern- Be it known that 1, WILLIAM S. SCALES, Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Box or Carton Setting p Machines, of whichthe following is a specification. This invention relates particularly to machines for forming the bottoms or closed ends of paper boxes or cartons, which as originally formed comprise tubes of paper scored longitudinally and also scored transversely near their ends, each tube being supplied in .a collapsed or flattened condition with its.-

ends, which are provided with flaps, left .open and the flaps extending in-the same plane with the side portions or rhembersof up'carton from the machine.

the box on which they are formed.

In setting u the carton the body portion is opened and eld in its desired form and'the. flaps at one end are folded to form the'bot tom end or head, the said flapsbein coated with glue and subjected to pressure etween an internal pressing member within the body of the carton .and one or more external pressing members. I The invention has for its object to provide a carton-setting-up machine having, first, means for facilitating the application of the carton to the'internal pressing member; secondly, improvements relating to the treat:-

ment of thefiaps comprising the bottom end or head preparatory to the completion of Said head, and, thirdly, improvementsrelating to the discharge of the completed or set- The invention consists in the several improvements which I will now proceed-to de scribe and claim.

hereinafter described, with the arms of the,

rotary carrier 0 and are adapted.- to be moved shaped to occupy the interior of a carton f, which may bezof the form indicatedini Fig.

progressively step by step by the movement of said carrier, each forming block bein'g 0 14, said figureshowingai carton which is oblong in cross-section 'aIIdfIS provided at its l ends-with fla f'ff f w e stood, however, "tha't the {forming blocks e I may-be formed' toccupy' 'a carton which is 2 square in oross section ovha n fl y other is provi ed at its outer endwith a series of. g' g, aid fingers1being pivot v slots e, formed inthe outer endof the'bloc k two of said slots extending at right angles with each other. The fingers g are thin metal pieces formed to fit and swing in the slots e. Each finger g has an inclined outer arm 9 and an inner arm 9 The arms 9 are formed so that when the fingers are in the positions shown in full lines in Fig. 7 the outer edge of each arm y will project at an incline from the outer end of the forming-block e in position to guide one end of a carton f onto the block and prevent the advancing end of the carton from catching on the end of the block. The block is provided with automatic means for forcing the fingers to the positions shown in full lines prior to the application of a carton to the block and then releasing the fingers, so that they may swing back to the positions indicated in Fig. 3 and by dotted lines in Fig. 7, the fingers being then retracted and contained Wholly Within the slots e.

The means here shown for projecting the fingers g comprise a push-rod or plunger g, which is movable longitudinally in the block e, arms 9 affixed to the saidplunger, pushrods g, afiixed to the outer ends of the arms and movable in slots or rooves formed for their reception in the bloc e, the outer ends of said rods bearing against the inner arms 9 as shown in Fig. 3, and a spring g, inter.

posed between a shoulder wit 'n the block 6,

and a stud or pin 9 affixed to the (plunger 9 The sprin g acts to normally hol the plunger 9 an rods g in the retracted position shown in Figs. 3 and 7. The plunger 9 of each block 6 is forced outwardly at a given point in the rotation ofthe carrier 0 by means of a fixed arm or cam 3', Figs. 1 and 3, which projects into the path in which the inner ends of the plungers g are carried and imparts to each plunger in succession a quick outward movement, causing the rods 9 to project the fingers g. The plunger is immediately released, leaving the fingers unsupported, so that the arms 9 will yield inwardly 'to the pressure of the advancing end of the body portion of the carton against them and will be swung inwardly to or nearly to their retracted position by the time the advancing end of the body portion has passed onto the sides of the block e. The outer edges of the portions of the fingers connecting the arms 9 and 9 project outwardly from the sides of the block when the fingers are projected, so that they oppose the movement of the body of the carton onto the block. Hence said body, which fits the block somewhat closely, exerts inward ressure on the fingers after' the flaps have een moved over the sides of the block, and thus swings the fingers to their retracted position. The fin ers 9 remain retracted until the block wlth which they are connected again reaches the fixed cam h. a

The mechanismvfor rotating the carrier 0 is organized in this embodiment of my inven- Fig; 1 it will be seen that the block e shown atthe left of said figure has just passed the fixed cam. Hence the fingers g of said block'have been projected and may be supposed to have guided the advancing ends of thecarton-fiapswhile the carton was being placedupon said block, the carrier being held stationary long enough to permit this operation. After the carton has been positioned the carrier c-is given a partial rotation, and the carton is moved in the direction indicated by the arrow ac in Fig. 1 toward an oscillating arm h, affixed to a vertical rock-shaft h, which is journaled in fixed bearings. The said arm h, which is provided with a curved finger h at its outer end,is oscillated be said stud being arranged to strike the lever h and thus move the arm h to the position shown inFig. 15. After the stud 7L passes the lever it the spring h restores the arm h to the position -shown in Fig. 1. The arm h is swung inwardly while the carrier 0 is in a motion and is so timed that its finger k strikes the forward vertical flap f of the carton and swings said flap forward against a vwing or supporting-bed 719, which moves with the rotary carrier. The arm h remains in the position shown in Fig. 15 until the movement of the rotary carrier brings the rear ver tical flap f of the carton against the finger h as shown in Fig. 16, the said flap-being thus turned outwardly against a wing or supporting-bed h, which also moves with the rotary .carrier. The vertical flaps f, f are now in position to receive-glue from a glue-roll i, which is located in outer surfaces of said flaps and apply glue thereto, the flaps being backed or supported by the wings k h.

7c represents a fixed guide having an in-' clined edge k, Fig. 10, which is arrang d to position to bear on the turn upwardly the lower horizontal fla f 2 of a the carton, as indicated in Fig. 17 be ore the said flap reaches the glue-roll 'i. The said lower fla is therefore coated with glue when the blocii which carries it passes the glueroll, and after this the rear vertical flap f is in turn presented to the glue-roll. V

The glue-roll '1' is aflixedto a vertical shaft 11, journaled in fixed bearings and rotated by suitable means, such as a belt running on a pulley 0?, Figs. 10 and 1 1, affixed to the lower portion of the shaft 'i.

acted on as above described has been brought into position to be actedon by a vertical roll m and a pair of fingers 0' o, the mo-- tion of the rotary carrier being arrested while the said roll and fingers are acting. The fingers 0 0 are arranged in a vertical plane and are moved simultaneously toward and from each other by the mechanism shown in Figs. 3 and 5 and hereinafter described.- When the movement of the carton is arrested, the

fingers 0 0 move toward each other, the upper:

finger o striking the u perhorizontal flap f of the carton and ben ing it downwardly, as

shown in Fig. 18, while the lower finger'o I 5 said flap being caused by he lipgf andhy the movementof ..thei-cai'rierito SWilHg.;iI1W8;1'dly Y bears upon the previously-bent lowerfla and holds thelatte'r in place against theen of the forming-block. The two flaps f 'f are thus held in place until the roll m has engaged the rear vertical flapf and folded the same partially over thei outer end of the block,

after which the fingers o 0 return to the-position shown in Fig.3 and the roll m advances to the position shown in Fig. 21, thus-pressing the rear flap f againstthe flaps f' 'f The roll m is moved from the position shown in'Fig. 20 to that. shownin Fig. '21,by-mechanism hereinafterdescribed, said roll occllpy ing the position shown in F' 2before acting on the rear-flap f v The sai flap has a tendency to spring outward intothe path ofthe roll m, as indicated in Fig. 2( so that when f the roll m is moving to the positionshownin Fig. 1 it engages the back or outer side of the flap, and thusfolds itinwardly' The fingers 0.0 are fixed to the long arm of bell-crank leverso of, which levers are piv-.

The oted at r to a fixed support, its other arm. having'a. trundle-roll 7* located "inia camgroove 1" in a diskafiixed to the driving-shaft p. The .said cam-groove is timed to hold the eblock by means "of aplaten r; which' is formed'to cover the outer end ef the block and the fla'.p'sv thereon and'is moved toaten r .is afiixed to one arm of a lever r, W ch,is pivplaten-in contact with the outer-flapon the third position and'to hold the said platen a retracted position while'the rotary carrier 0 is in motion.

At this oint it should be noted that theforminglook a is pivotall connected with the rotary carrier 0 in 'suc belt t, whichmoves in the irection. required I left in Fig. 3, to a vertical position over the outlet 8, as shown at the right in Fig. 3, so

thatthe completed carton may be forced downwardly from the block, and thus 'conveniently and advantageously'removed.

The preferred construction whereby the block may be turned to discharge the finished carton downwardly and the preferred mechanism for changing the position of the block will now be described. it represents a U-shaped yoke or frame. The outer ends of the arms of the yoke u, are provided with trunnions u it, which are journaled in bearings in the outer ends of the carrier-arms 0 0 the yoke a being located between and pivotally connected with a pair of the carrier-arms 0 The central or neck portion of the yoke u is provided with extensions u if, projecting from opposite sides of the yoke and formnig with said neck portion of the yoke a head to which the forming-block e'is attached by screws u It will be seen that the yoke engaged as described with the block and pivotally connected with the carrier enables the block to assume the diflerent positions indicated in Fig. 3, the oke and block turning together on the axis ormed by the trunnions u of the yoke. The block is held in a horizontal position while it is receiving the carton and during the described operations thereon by means of a cam n affixed to the bed a and having a cam-groove u which is engaged by a trundle-roll u on one arm of a lever it, which is pivoted at u to the rotary carrier 0. The other arm of the lever to is connected by a rod 11." with an arm u affixed to one of the trunnions u of the yoke w. The major portion of the cam-groove a is concentric with the axis of the rotary carrier c, this concentric portion controlling the lever a, while the earton'is being applied to the block and during the various operations preceding the stripping or discharging operation, the arrangement being such that the concentric portion of the cam in cooperation with the lever 11, holds the block in a horizontal position. Another portion of the camroove a (shown at the right in Fig. 3) is ormed-to raise the lever 'u, to a substantially vertical-positionfthus causing it to swing the block with which it is'connected also to a vertical' position, as indicated at the right in Fig. 3'. This takes place when the block reaches the position represented at the top of Fig. 1, the carrier being stopped when the block is in a vertical position and held a sufficient length of time to permit the ejecting device next described to force the carton downwardly from the block. The said ejecting device comprises a cross-head 12, which is movable on vertical guides on a standard o,

afiixed to the bed at, arms]; 0 aflixed to the cross-head v, and fingers v afiixed to'said arms. The cross-head v is reciprocated vertically by means'presently described, and the fingers v are formed and arranged to enter longitudinal grooves e formed in two opposite sides of the forming-block e. The fingers v commence their forwrad movement when elevated above the upper end of the block, as shown in Fig. 3, so that they strike the upper end of the carton and force it downwardly until the carton drops from theblock onto the conveyer t. After the fingers have discharged the carton they immediately return to the raised position shown in Fig. 3, so that the forming-block is free to swing back to its horizontal position. The cross-head v is reciprocated by means of a cam-groove v in a disk aflixed to the driving-shaft p, a rockshaft '0 journaled in bearings afiixed to the bed a, an arm 4), afiixed to said rock-shaft and having a trundle-roll v7, engaged with said cam-groove, an arm 0 affixed to the rock-shaft v and a rod 0*, connecting the arm 12 with the cross-head 'v. The camgroove 12' is formed to oscillate the arm v and thus cause the reciprocation of the crosshead and. the stripping-fingers.

The preferred. means for imparting the described step-by-step rotation to the carrier 0 comprise a driving member mounted to rotate on a vertical stud 40, Figs. 2 and 9, aflixed to the bed a, said driving member comprising the crescent-shaped part 10 and an arm to affixed thereto, and a driven member w affixed to the tubular shaft (1 of the rotary carrier, said driven member comprising a wheel having a series of radial slots w? and a series arranged as shown in Fig. 9, so that each rotation of the driving member causes the pin 11) to enter one of the slots w, and thus impart a partial rotation to the driven member, said rotation continuing while the pin w moves first inwardlyand then outwardly in the engaged slot, the rotation of the driven member stopping when the pin leaves the slot and being discontinued until the pin enters the next slot. The driving member,which is rotated continuously, therefore imparts a step-by-step rotation to the driven member and to the carrier 0, to which said driven member is aflixed by a set-screw w", Fig. 3.

The fixed cam which projects the finger operating plunger g in the forming-block, is supported by a stationary rod or post 7', which extends through the tubular shaft d and is afiixed at its lower end by a set-screw IIO I 7' to a bracket y, attached to the bed a. It

will beunderstood'that the foregoing description of the forming-block e and means for operating the same applies to each of the forming-blocks ofthe series. if

The operation of the machine may be briefly recapitulated as follows: While the rotary carrier is at rest the operator opens a carton and applies it to the forming-block which is nearest the flap-turning finger 71. and glue-roll 71. The next partial rotation of the carrier advances the block to the position occupied by the flapand pressing-roll m, the vertical flaps and the lower fla of the carton bein adjusted and coated wit glue while in transit, as above described. The carrier remains stationary while the fingers o o and. the roll m are acting and is then advanced to,

cause the guide-strip g and its lip g to fold the last flap, this movement carrying the carton to the pressing-platen 1*, where it is held for the action of said platen, after which the carrier is again moved forward to bring the block over the outlet 19, the block being then 'ber is .an element.

moved to a vertical position. fingers b then discharge the carton, and the block is returned to its horizontal position, after which the carrier is given another partial rotationto bring the block into position to receive another carton, the guiding-fingers 9 being projected just before the block reaches its carton-receiving position. The block 1; internally supports the flap portions. of the carton against external pressure exerted on' them. Hence said block serves as apressing member. .The flap-guiding fingers. 9 ma' terially facilitate the engagement of a carton with the pressmg member and increase the 'effec tiveness of the machine of which said memare not limited, however, to use 1n a pressing member formed and operated as SllOWl'l'lIl .this embodiment of my invention, it being extended from their original position at right angles to the path of movement of the cartonsupporting block to a position substantially 1n the line of said path. Hence a glue-roll located adjacent to said path and opposite the outer end of the block e is-in position to apply a coating of adhesive to the extended front and rear flaps f f. successively or to either of said flaps, said roll being also in position to applya coating to a flap f bearing on the end of the block between the two extended flaps.

Havingthus explained the nature vention and described awa and using the same, although attempted to set forthall the forms in which of constructing The stripping-- The flap-guiding fingers ously ofmyin-= said plunger is Without having it may be embodied or all the modes, of its use, I declare that what I claim is- 1.
