WRAPPER FORMING AN D LABELING MACHINE.

' Specification of Letters Patent.

Patented Apr. 22,1913.

Application filed December 16, 1905. Serial No. 292,101.

, To all whom it may concern Be it known that I, ANDREW 1V. LIYING- STON, citizen of the United States, residlng at Alameda, in the county of Alameda and State of California, have invented new and useful Improvements in Wrapper Forming and Labeling Machines, of which the following is a specification.

My invention relates to a paper wrapping means, or machine for forming paper tubes, bags, wrappers, applying labels and the like, and pertains especially to an apparatus for folding a bag, wrapper or carton-blank into tubular form of the bag, wrapper or carton. Its object is to provide a simple, practical continuously-operating machine of the above character having large capacity and capable of a wide range of utility, and particulary designed for forming rectangular packages or applying labels to square or polygonal cans. The invention consists of the parts and the construction and the combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which Figure l is a side elevation of the principal parts of my invention, the table being elevated more than in the actual machine for the purpose of showing certain features which would otherwise be obscured or confused. Fig. 2 is a plan view of a former and the wrapper-blank-supporting table. Fig. 3 is a side elevation of the wrapping mechanism. Fig. 4 is a plan View of same. Figs. 56-7 represent different positions of the wrapping means and holder during the wrapping and sealing dperations. Fig. 8 is a detail of the latch mechanism for the underneath. gripper arms.

A represents a carrier of any suitable description: here shown as of the endless chain variety passing over the sprocket 2 mounted on and driven from shaft 3 by any appropriate means.

Carrier A is supplied with one or more wrapper holders 4 arranged or held to one side of the carrier so that a wrapper or label can be readily passed clear around a holder. By holder I mean any article or body whatsoever capable of being supported to permit a wrapper or label to be wrapped or folded about it by my wrapping mechanism.

5 is a frame or carriage conveniently mounted to have a limited intermittent preparatory to the completion frame, and a roller 8 on a reciprocating gripper arm 9 operates back and forth in this groove. The arm 9 is downwardly curved at its outer end and carries a roller 10. A similar but shorter arm 9 with a roller 10' is arranged on the opposite side of the frame and is rigidly connected with arm 9 by the rod 11. Two levers 12 are pivoted at one end to the rod or piece 11 and are fulcrumed to frame 5 at 13. A spring 14 acts on rod 11 and levers 1-2 to tend to draw the latter and arms 99 normally together scissorsfashion. Each lever 12 is connected with a togglev 15: one member of toggle 15 being pivoted to a lever 12- and the other member pivoted to a fixed point of support at16.

The toggles 15 are connected with the extension 6 of frame 5 by the links 17 while the extension 6 connects by a link 18 with a rocker arm 19 fulcrumed at 20.

Arm 19 carries a roller 21 arranged in the path of the moving holders 4 so that each holder as it comes along will engage roller 21, depress arm 19 and the extension 6, thus raising the front end of frame 5, breaking toggles 15 and pulling back on levers 12 to retract the gripper arms 9-9 into sition shown in Figs. 1-34 and 5. It will be understood that if the toggles 15 are lifted to straighten them as shown 'in dotted lines Fig. l and in full lines, Figs. 67, the gripper arms 9-9, with their rollers 10-10, will be shot forward for the purpose of engaging over the top of a holder 4 to assist in holding the wrapper blank in position as will be more fully explained later. The means for grippinga sheet to the underside of a holder in opposition to the gripper arms 9-9, comprises the springactuated foot-piece or gripper 22 pivotedto the pothe jointed arms 23 which are fulcrumed at 24 to frame 5. Each arm 23 is made in two sections pivoted together at 25. The arms of one section are pivoted to and between the ends of the other section so that the latter section leaves a short projecting end 26 beveled on its upper-side as at 27. A springactuated latch member or trigger 28 1s pivoted intermediate of its ends to one of said sections asat 29, and has a lateral projection 30 adapted to engage the projection 26 on the other section to hold the two sections rigid in line as shown in full lines'Figs. l5 and 6 or toobe tripped to release projection 26 and leave the sections to assume an angular position as shown in dotted lines Fig. 1, or as shown in Fig. 7, for the purpose of releasing a holder after the wrapper is formed.

The lateral projection 30 is arranged to ride up the bevel 27 and to catch over the top of the projection 26. The pivot of the arm sections consists of a rod which is surrounded by a coil spring 31 which acts latch member or trigger 28 is shown pivoted on the rod 29, which latter carries a spring 32 acting to throw the latch member normally into the path of the project-ion 26 so that when the arms after being released from their position indicated in Fig. 7, straighten, the projections 30 on the latch member will ride out around the projection 26 and engage over the top of the latter to maintain the arms in rigid straightened position.

The arms are only bent by tripping the I latch or trigger 28 to carry the pro ection mounted independent of frame 5.

30 over and in front of the projection 26 .to release the latter. The tripping of the latch is done by the engagement of the rear end of the latch or trigger with a fixed stop 33 This stop 33 is, encountered during the oscillation of frame 5 from the position of Fig. 5 to that of Fig. 7.

A spring 34 acts on'arms 23 to press them normally upward into position shown in Figs. 3 and 5.

proper degree of the arms 23, their sections, the latch 28 and the foot-piece or gripper 22. A third folding and pressing instrumentality carried by frame 5, is arranged to operate between and about at right angles to arms 9+9 and the gripper 22 and con-' junctively with these parts to hold the Wrapper blank to and on the holder. This comprises two pivoted spring-actuated pressers 35 carried by the spring actuated arms 36 which are pivoted at 37 to frame 5.

The springs '38 and 39 tend to hold the pressers in suitable operative position relative to the path of movement of the holders and the resiliency and scope ofv the pivotal connections of the parts 3536 are suffi- ,cient to allow the parts 35 to assume the various positions indicated in Figs. 15-6 7.

The mechanism for folding the fourth side of the wrapper andfor sealing the side Suitable stops not shown are provided to limit the movement in the edges of the wrapper, assuming a four-sided or polygonal wrapper to be turned out by this machine, is-carried by a fixed part of the machine frame. This folding and seal ing mechanism will be described and better understood after setting forth the operation of the machine up to this point.

The Wrapper blank or label 40 is laid on a table 41 against the guides 42 and over an opening 43 in the direct path of a holder 4. The table is disposed-just above the frame 5 and the parts which I "have described.

The opening 43 is partly closed. in front by the hinged flap or trap door 44. The latter reduces the size of opening 43 so that the flexible blank will not sag, or fall through accidentally, when laid on the table and in the path of an approaching holder. But flap 44 is adapted to be opened, by mechanism operated by a holder in advance, just as soon as the blank is caught by gripper 22 and the holder above. In fact flap 44 drops for just an instant to let a holder pass and then lifts to support the next blank which meanwhile is'beingplaced by suitable means in position on the table. Explanation of the flap-actuating-means is deferred until I come to the description of the means for actuating. the paste roller, since one means includes more or less the other.

With the arms 23 and gripper 22 in the position shown in Fig. 5, the holder and gripper 22 co-act to seize upon the wrapperblank lying on the table, and carry it on gripper 22, a succeeding holder encounters roller 21 of arm 19- tobreak the toggle 15 and retract the arms 9-9' out of the way of the descending holder which is bringing the wrapper blankiwith it. When the levers 12 are thrown back to retract arms 9-9, they engage hook members 45 carried by the arm 36 and draw them and the pressers 35 also out of interference with the approaching holder and wrappen.

When the levers 12 are'thrown back they encounter the stops 46 carried'by the rockshaft 47, the function of which stops, actuated by spring 48, is to resiliently support the levers 12 and arms 9-9 and rollers 10-1 0 so that the latter will press with the proper degree of force against the adjacent vertical side of the descendin holder and roll the adjacent projecting end of the wrapper up against the back of the holder.

The holder and wrapper continue to descend causing arms 23 to turn on their pivots 24; and as-the top edge of the holder comes in line with the rollers 1010', a sucllt ceeding holder which has been meanwhile pressing down on roller 21 to maintain the toggles in bent position with the arms 99' retracted, leaves roller 21; thus leaving. the

toggles free to straighten. During the trav roller 21 is released, the arms 23 encounter a stop 23' on the frame 5 and rock thelatter; which results, through the medium of link 17, in the straightening of the toggles 15 and the forward projection of arms 9 .9 and the hooking of the rollers 1010 over the top and front edge of the holder; which is the position of Fig.- 6 and the first dotted line position of Fig.1.

Thecam groove 7 has an angular or irreg ular part7 around which the roller. 5} travels in the forward projection of the arms 99 for the purpose a of carrying the rollers 10 10 up over the top corner of the holder properly.

nearest frame 5 and down again on top of the holder in such fashion that the rollers 10-10 follow the periphery and the motion of the holder and remain in constant contact therewith at all times during the folding operation sothat there is no chance of the paper slipping.

The roller 8 is in fact a movable fulcrum for the arms 99 and the latter have both a reciprocating and an oscillating movement for the purpose of allowing the rollers 10-10 to follow the motion of the holder; and to perform their functions he pressers and rubbers follow. the rollers 10-10' in their-initial-operation of folding up the rear end flap of the sheet 40 against the rear vertical side of the holder, and serve to press the sheet against that side of the holder while the rollers 10-10 are shooting forward across the top of the holder to the holder. With the several grip members 10-10 35 and 22 inthe posit-ion last described, Which' is that of Fig. 6, the holder is gripped on all four sides and only the lower front end flap of the sheet remains to be folded up and pasted.

The holders each carry a roller projection 49 which is adapted to trip one end of a lever 50. The other endof this lever is connected by a link 51witl1 a lever 52 which is fulcrumed at one end at 53 and is pivoted- .at the other end to a member 54 having a segmental slot Member 54 is supported and guided by a'roller 56 passing through slot 55. The parts 52-54 constitute a toggle frame or carrier for the pasting roller 57.

A plate 58 carried by the toggle frame is arranged "parallel with and immediately in front of the paste roller and is designed for grip over the'upper front edge of one thing to engagethe front side of the holder and keep flat that depending flap of sheet 40, which has just been bent over the front of the holder by the rollers '1010. Another purpose of the plate 58 is to maintain the paste roller 57 out of contact with the holder.

. The paste is applied by bending up the lower horizontal flap 40 against the under side of roller 57. This is done by the springactuated, pivoted presser 59 pivoted, to the spring-jointed, spring-actuated lever 60 ful- The engagement-of the underside of a holder with the presser 59 takes place at about the same time that the plate 58 is brought for.- ward against the turned down flap 7 of the blank on the front side of the holder.

The trap door 44 connects with a lever 62 fulcrumed at 63; the pivotal connections of the two ends of the lever being slotted to allow-of the proper movement o-f'the parts. Lever 62 is connected with toggle-member 52 by a link 64 so the door is dropped or raised according as the paste roller movement is from or toward the path of the holder and by the same lever 50.

.The paste roller is thrown in toward the holder and the door 44 raised by the actuation of the lever 50 by the roller 49. Subsequently the paste roller is moved out again and the door dropped, by the roller 49 en- 50 in the opposite'direction, leaving lever 50 ready to be encountered by a succeeding holder. Thus each holder operates on both levers 50-65 to actuate the door. 44 and paste roller in the proper fashion. Each holder actuates the paste roller to apply paste to its own wrapper; but in order to let a holder pass through the table the flap is operated by an advance holder. For instance in Fig. 5 I have shown the relative positions of five holders designated vwwyz, and in Fig. 6 the advanced positions of o-m-y are shown. In Fig. 5 holder 2 has not yet opened the door 44 for holder 3 (see Fig. 1). holder y has passed through opening 43, tripped lever 50, closed the door 44, and moved "the paste roller 57 into the position indicated.

The paste is contained in any suitable receptacle and is applied to rollers 57 by any appropriate mechanism. As shown ,66 represents a paste reservoir having a series of geared distributing rollers 67 operated by any suitable means to deliver paste to the with which the paste roller 57 periodically contacts.

In operation with the trap door 44 in raised or closed position as shown in Fig. 5, a wrapper blank is laid on the table across opening 43' and against the guides 42 and l in the path of a descending holder. A succrumed at 61 to a fixed part of the ,machine.

gaging a second lever 65 which rock-s lever combined guide and distributing roller 56 ceeding holder, as indicated at-w has ridden upon the roller 21 to break the toggles and retract the arms 99. As the holder y comes down on top of the sheet the jointed arms 23 are raised and straightened and the gripper 22 comes up on the underside of the sheet to grip the latter against the bottom of the holder. It is understood that in this machine the holders are assumed to move continuously' As soon as the holder'y and the gripper 22 have seized the sheet, the advance holder 2 has tripped lever 65 to throw back the paste roller and-cause the trap-door 44 to drop and allow the holder 3 to pass through. As soon as the holder y is well through the aperture in the table, holder 1 engages the lever 50 closes the door 44 again and throws the paste-roller with its guide and presser-plate 58 into the position, shown in Fig. 6. Meanwhile, the rollers 101 0 on the arms 9-9 have traveled up the back of the holder. and carried the adjacent projecting end-flap of the wrapper up against the holder; the pressers coiiperating to p013 the wrapper flat and tight against the 101 er.

to oscillate in unison with the arms 23 and rollers 1010' and the upwardly projecting flap end of the wrapper across the top of holder y and over the front corner of the holder, all as indicated in Fig. 6. The engagement of the underside of the holder with the presser 59 takes place at about the same time that the plate 58 is brought forward into contact with the front side of the holder, as indicated in Fig. 6. The purpose of havingthe cam slot 55 is to cause the roller 57 to travel in an are which is substantially reverse of the curve of the slot 55 sothat the paste-roller will-come down on top of the projecting flap 40. If the pasteroller moved directly inward on a horizontal line it would be more likely to catch the projecting edge of flap 40 and crumple it up; while as it is, it is carried above and then downwardtoward the descending fiap 40, as indicated. The further downward movement of the holder bends the presser 59 into a vertical position so that the edge of flap 40 is brought against the underside of the paste-roller 57 thereby receiving the proper amount of paste and is then pressed inward beneath roller 57 v and plate 58 against the previously folded upper end flap as indicated in Fig. 7. With the wrapper blank thus folded about the four sides of the holder and with the edges pasted,

j and with the presser 59 still in contact with sults inthe arms 23 breaking at their pivots the overlapped pasted edges of the wrapper,

the 'arm 5 has been moved down until the latch 28 has engaged the stop 33 which re As the holder to (Fig. 5) passes 0E of the roller 21 it leaves the frame 5 free with the roller 21; the gripper 22 leaving the holder :1 in ample time to assume its normal position of Fig. 5 to engage a fresh wrapper blank with the immediately succeeding holderm, the operation being repeated with each succeeding holder.

It is possible that Various modifications of my invention may be made without departing from the principle thereof, and I do not wish to be considered as limiting myself to my specific construction beyond what is required by a reasonable interpretation of my" claims,

It is-to be'nofed that flat pressers or grippers 22-35 and 59 are used instead of rollers. It has been found by experience that rollers would not do the work satisfactorily Fig. 5. There is no difference in operation between the use of a can and of a former, as the wrapper or label is wrapped about both. Having thus described my invention, what I claim and desire to secure by Letters Patent, is
