To all whom it may concern:

Be it known that I, AUe sTUs E. Bui- MERLE, a citizen of the United States, residing at Edenvale, in the county of Santa Clara and State (if California, have invented new and useful Improvements in Packaging-Machines, of which the following is a specification.

Myinvention relates to packaging machines for packing dried fruits, raisins and other things in package form. Its object is to provide an automatic, labor-saving machine of maximum capacity which will make itsownpackage'from a pro erly prepared sheet of paper, the latter belng lined,

if desired, with a paraffin paper lining, and

which machine will have meansfor filling the package or carton and for folding or closing the ends of the carton and for discharging the finished product. p 4 Having reference to the accompanying drawings1*igure 1 is a longitudinal vertical section of the machine. Fig. 2 is a transverse vertical section on line B-B, Fig. 1. Fig. 3 is an enlarged horizontal section taken on line CC, Fig. 2. Fig. 4 is a plan view of the upper portion of the. machine.

folding devices. Fig. 12 is a plan of the carton blank. Fig. 13 is a sectional elevation of the device for folding the carton aronnd'the tube. Fig. 14 is a diagrammatic trating the manner in whichthe wing plates fold in the side flaps of the carton.

A represents the stationary framework of the machine. 2 is a rigid hollow column thereon supporting in suitable bearings the hollow shaft 3, which latter carries theintermittently revolving spider 4:. This spider 1 is shown as having four arms, each larm supporting a hollow wrapper former 5 about which the carton is wrapped, and over the lower end of which one end of the carton is folded, the fruit being delivered at the proper time lnto the top of the former,

pushed down t-hereinto, and the fruit andi wrapper discharged from the ,former; suit able mechanism, hereinafter to be described,

being employed to closethe open end of the filled carton,

Intermittent motion is given to the spider by any suitable means. As here shown, the lowerend of the hollow shaft3 carries a miter gear 6 meshing a corresponding gear 7 on a shaft 8. j

9 is the drive-shaft receiving continuous motion through the worm gearing 10, and intermittent motion is transmitted to shaft 8 through suitable connections, as the stop.

movement 10"; the idea being to give the shaft 8 and s 'ider a quarter turn at each full revolution 0 the drive-shaft 9.

A sheet of paper or carton blank suitably shaped and notched, and represented at X,

Fig. 12-, is placed over a device 11, F igs'. 2- 3-5, and engaged in suitable spring clips 12. The devire 11 is suitably mounted so as to have a movement toward and from a former 5wvhen the latter is at rest, to lay the carton blank against the side of the former 5 and fold the same around three sides of said former. As here shown, this foldiiigrlevice 11 comprises a box-like frame holding, two lobes plates or jaws 18, one on each side of the frame 11 and held in place by the bolts 14 and springs 15; the bolts and plates having a limited yielding move- -ment so that when the folding device is brought forward towartb a former 5, the side plates 1 3 will yieldingly embrace the sides of the former Band carry the end of the wrapper'around the former. 'The clips 12 are carried on a skeleton-like frame 16, which latter is secured to and moved with the box 11; the clips 12 being disposed on ill each side of the plates 13, and being so positioned that when the ends of the carton blank are drawn out of the clips, these ends will be allowed to pass around behind the former 5, where suitable devices operate to overlap and seal these edges.

The box 11 is pivotally mounted on a sliding carriage 17, which latter slides back and forth in suitable guides 18; the box 11 being pivoted to the carriage 17 at 19. The back of the box carries a projecting cam 20 which engages, at each forward or inward reciprocation of the carriage, a horizontal rigid stop 21 by which the box. is turned from a horizontal to a vertical position, as indicated in Fig. 2. As the carriage 17 moves outwardly from the center of rotation of the formers, the cam 20 rides off of the stop 21, while a spring 22 tends to lay the folding device 111312 fiat into horizontal position ready to receive the next carton blank.

The reciproeatory motion of the carriage 17 is produced by any suitable means. As

here shown, a pair of links 23 connect arms 24 on carriage 17 with a bell-crank lever 25, which latter is fulcrumed at 26 and oscillated at suitable intervals by engagement with a cam 27 on shaft 9.v

The carton formers '5 are preferably provided with sharp corners produced by extending the face and back plates of the former tube a short distance over the side plates,'as represented in Fig. 3; the purpose of these shar corners being to produce a well-defined s arp edge or corner on the resulting package.

After the folding device 11-13 has placed the carton around three sides of the former tube, the next operation is that of folding in the edges of the carton blank, which is done in two operations; the first operation being accomplished by a pivoted comb-like device 28, and the second operation being done by a swinging roller-bearing arm 29. Prior to the operation, however, of these devices 28-29, the paper sheet while still lying in horizontal position in the clips12 receives some paste on its under side and adjacent to one of the clips 12. This pasting mechanism is shown in Fig. 2 and consists of a paste box 30 up through which operates a rod 31 carrying at its upper end a paste-brush or pad 32, which alternately.

is drawn down into the paste and then raised upward into contact with the carton blank in the clips 12 before the carton blank is lifted and wrapped around the former tube 5. Any suitable means may be employed to effect the proper reciprocating motion of the paster 32. As here shown, the lower end of the rod 31 is connected by a link 33 with a lever 34 fulcrumed to a fixed part of the frame, as 35, and intermittently operated by a cam 36 on shaft 9.

The folder 28 is pivoted on the bracket 37 and is adapted to swin in a vertical plane and come in just behind the forme'r tube 5, about which has been wrapped the freshly pasted carton blank; this folder 28 engaging the pasted end of the blank and carrying the latter around behind the former tube and laying it flat against its rear vertical side. Any suitable means may be employed to effect this oscillatory movement of the folder 28 synchronously with the operation of the other parts of the apparatus. As here shown, the bracket 37 is rigidly secured to a carrier 38, which latteris mounted rigid on the parallel sliding rods 39. These rods 39 are arranged horizontal and parallel, and are supported in suitable guide boxes on either side of the column 2 and travel together backward and forward intermittently; motion being imparted to them from the cam 40, Fig. 10, which receives two impulses from the revolution of shaft 9 from the rotating arm 41 on the latter. It will thus be observed that the carrier rods 39 have two movements, one forward and one back, to one movement of the several former tubes 5. Thus, when the rods 39 move in one direction they carry the folder 28 with them and cause a toe portion 42 on this folder to engage a fixed stop 43 and turn the folder up into vertical position. The continued movement, in the same direction of the rods 39 then causes the fingers 28' of the elevated folder 28 to move across the back of the adjacent former tube 5 and lay the edge of the carton against the folder with the pasted portion outward. As soon as this operation is done, a cam 44, Fig. 4, engages the arm of arock shaft 46, which latter yieldingly Cfll'ljCS a folding roller 29,

to swin the latter in a horizontal lane in- O. P

a direction opposite to the just described motion of the folder 28, and thereby fold in the other edge of the carton blank over the pasted edge which has just been laid flat against the former tube by the folder 2S.

These folders 29 are disposed vertically and have a limited radial movement on a respective horizontal arm 47which is fixedly secured'to the shaft 46. There are four of these folder rollers 29, one for each former tube and each with its. separate shaft, and they all travel with the spider 4. Eachshaft 46 is disposed vertically and journaled in suitable hearings in the spider. The cam 44 has only a. rocking movement, and is so fashioned that the rollers 29 will normally be in contact with its particular former tube, except duringabout a quarter of a revolu tion of the spider.

The rocking cam 44 is fixed to the rock shaft 48 which extends down through the hollow shaft 3 and has a crank arm 49, at the lower end of which a link 50 is connected; this link 50 also being connected with a bracket arm 51 mounted on the cam 40. l1-l213 is lifted to put a carton blank about the former tube, the cam 1'4: is rocked to carry the roller 29 to one side, as'is seen in Fig. 4. out of any interference with the proper folding of the paper about the former tube. Then, after the folder 28 has been elevated and folded in its end of the carton,

the cam is rocked so that the arm of the just mentioned roller will ride off of the point of the cam, allowing the spring 52 to act to pull the roller 29 around and against ber, and the springs at? with the loose connection of the roller brackets on the stems .allow these rollers to accommodate themselves yieldingly to press the paper with just the rightpressure against the former tubes,

The several positions of the fcirmer tubes in the cycle necessary to form and complete a package are represented by the characters (1 Z), c and (1, position a being the one for receiving the carton blank and having itfolded and pasted around the tube. 'lVhen the spider makes its next move it carries this former tube, with its encirclingwrapper, and witlrits rubber roller 29 still in contact with it, into position 7). While in this position the lower end of the wrapper is closed by the following mechanism: The rods 39, which it will be observed extend parallel with the positions represented by b and (Z, carry adjacent to position 6' two brackets 5556 which carry suitable folding devices adapted to operate successively on the carton end flaps which hang down below the former tube 5, The bracket 55 carries a plate 57 which has two underneath wing plates 58; these wing plates being secured to rock shafts 59 onthe bracket 55. The

shafts 59 extend downwardly and carryin \vardly projecting arms 60 which are designed to be engaged with respective stops 61-62 on alternate reciprocations of the rods 39. The bracket 55- with the plates 57 58 are arranged on the inside of the circular path of the former tubes, and are so disposed that when a tube is brought to rest,

the lower projecting flap ends of the carton on this tube will be directly in the path of the plate 57, so that when the rods 39 are operated to move the frame 55 outward, the plate 57 will fold one flapof the-earton over the lower end of the former tube, and

Just before the paper-holding device' by the rods 39'. of their return stroke and the plates 57 -58 at the proper instant the arms 60 on the rock shafts 59 will engage a stop 61, causing the wing plates 58 to fold inwardly in ashear-like manner beneath the plate 57,

thus folding in the two side flaps of the wrapper projecting below the former tube. This position of the plates 5758 is maintained until the rods 39 move backward again, when the plates extract themselves \from the folds thus performed, but are closely; followed by a pivoted plate 63 on the bracket 56, which latter is also carried As the rods 39 near the end withdraw from the folds of the carton, the arms 60 on the spindles of the wing plates encounter the dead stop 62 which opens the wing plates in readiness for the next opera- -tion.

The plate 63 on moving inwardly across the lower end of the former tube, folds upward the remaining flap, thus closing the lower end of the tubular carton. Suitable means, not necessary here to be shown, may be employed to apply paste to this flap which is folded up by the plate 63.

The plate 63 is pivotally supported on the bracket- 56, and is spring-actuated to cause it normally to stand upright. However, it

is held horizontal against the tension of this spring by means of a latch 64 engaging the catch 65 on plate 63. The catch 64 is mounted on the spring-actuated rod 66, which carries a-little crank arm 67 at one end. The shaft on which plate 63 is mounted carries a crank arm 69 at the end opposite to crank 67.

In order clearly to understand the operation of the plate 63,-a-nd its functions, itis to be said that in the initial movement of the rods 39 to carry the folders 5758 underneath the former tube, simultaneously the plate 63 is moved outward and away "from this tube. In this outward movement 56 and folding plates,.'

of the brackets 55 the arm 69, previously referred to, engages the fixed stop 70 and turns the plate 63 into a horizontal position so that the catch 65 will engage with the underneath spring latch 64. The folder 633 will thus be held in operative horizontal position until the arm 62' engages a. fixed releasing stop 71, on the that when the plate 63 is in the vertical inoperative position ust descrlb'ed, and the bra Cl inward movement of the parts. The latch &

ets at their limit of inward movement, and stationary, the former tube with its carton end to be folded can readily pass in between the vertical plate 63 and the end of the horizontal plate 57; the subsequent folding op-,

erations of the plates 57-63'having already been clearly described.

From position Z), the former tube, with the end of the carton closed, passes forward to its thirdposition, indicated at c. As the tube and carton move off of the pivoted plate u l 63 they pass on to the semi-circular stationary horizontal plate 7.2, which latter is preferneath a feed hopper 7a. through which the material to' be packaged, having been propcrly weighed, is delivered into the tube. A

card of pasteboard pr a piec e of stiff paper, or any otherdesirable material, is usually placed on top of the fruit inside of the former tube; the object of this card being to prevent the fruitsticking to the plunger 75 during the next succeeding step of compressing the fruit. A further object of inserting this card is to assist in making a square fold on top of the package. The former with its wrapper having received its charge of fruit or other material at c, is next'moved to position d. In so doing the bottom of the package slides over the semi-circular support 72, The former tube and its package having arrived at its final position d comes directly into line with and between the plunger 75 and the mold 76. The plunger 75 is carried on a cross-head 77, which moves up and down on suitable standards 78 and is operated by suitablecrank and pitman connections 79 iial slot 82 in the cross-head 7 7.

from shaft 9. 80 is abracket fixed to the rods 39' and supporting avertical rod 81 which extends upward through a longitudi-' The rod 81 carries a block 83 which has a tight sliding fit up and down in the bracket 80. This block carries two flat plates 8 l85 suitably spaced apart, and these plates are adapted, when the bracket 80 has moved in toward the filled former tube, to pass in underneath the former tube, so that the top plate 84 will come directly across the lower end, of the former tube and underneath the closed package and a continuation of the support 72 while the lower plate 85 will pass in through a slot 86 in mo1d'76, and close the top flap ofa previously filled package, which during plates 84. to travel downward inside the V mold 76; these plates being extracted when they have reached the lower end of the movement, and onthe reversal of travel of the rods 39, through a suitable horizontal opening 89 in the mold. This downward movement of the plates 8485 through the mold is effected by the plunger pushing down on the superposed material in the former tube. "When this former tube with its filled package is first brought into position d, the plates 8al-85 are moved inwardly in the manner just described, the top plate 84 serving to support the filled wrapper which is still on the tube. The plunger 75 now moving downward enters the former tube and compresses the fruit inside of the tube cross-head 77 in descending next strikes a tappet 90'on rod 81, causing the plates 8485 to move downward inside of the mold 76; this compressing movement continuing until the plates 84-85-come opposite the opening 89 in the mold. On the withdrawal of the plates 84t85, the package which has just been stripped off of the former tube is left in the mold 7G. Suitable folding devices are then operated to close the top of the filled package.

' As here shown, the rods 39 carry a bracket 91 carrying at its top a pivoted plate 92, and having on its top side two pivoted wing plates 93; these wing plates 93 being similar in modeof operation and function to the wing plates 58, previously described. The spindles of these wing plates carry inwardly projecting arms 94 which engage respective stops 9596 at opposite ends .of their stroke, to open and close the wing plates. The plate 92 is mounted on the horizontal rock shaft 97, and the under side of the frame or bracket 91 carries another pivoted plate 98, which is also mounted on a rock shaft 99; and these rock shafts have inturned arms 100 which engage respective stops 101-l02 at opposite ends of 'the stroke of rods 39, for the purpose of slightly opening and closing the plates 92-98 toward and from each other. Sprin 'brakeS-103 act on the rods 9799 to limit the free turning movement of the plates 92-98.

The operation of the folding devices 92-98 is as follows; assuming that a filled package with its top still open has been pushed down into the mold 7 6 and left in position in between the path of movement of the two The .tion (Z.

plates 92-93: on the movement of the rods of the top of the package, and when the little crank arms on the spindles of the wing plates 93 strike the stop 95, these wing plates fold in the two side flapsof the package. Then when the plates 8485 are next projected into the mold, the lower plate 85 closes over the remaining top flap. The plates St -85 serve to space the package thus finally closed on top from the package just above which is to be discharged from its former tube. Then onthe down movement of the plunger the filled and finally closed package is pushed down by the descending plate 85 and is finally ejected from the mold by suitablemeans, as the kicker 107, which moves with the carriage 17. At the same time that the plunger '75 descends to compress the fruit at position (Z, a wiper 108 comes down and swabs out the inside of the empty tube which is at position a." This wiper or swab 108 consists of a sponge, or any other suitable moisture-holding material, and is carried on a hollow rod 109 sup- I ported from the cross-head 77. The rod 109 communicates with a small tank 110 con-' taining water, so that the wiper ordinarily contams enough water properly to swab out -the empty former at position a and prevent its becoming sticky. This wettin of the inside of the tube facilitates the, discharge of the fruit therefrom when it reaches posi- The operation of the apparatus is briefly as follows: folding 12. At the proper moment this carton blank is'lifted into verticalposition and laidabout three sides of the former tube, in. position a. The rods 39 are then actuated to cause the folder 28 to operate on one edge of this fresh carton blank. Simultaneously the plates 57-58 act on the lower end of a carton which has previousl position Z); also simultaneously theplates 8384 move inward into the mold 76 so.

that the plate 85 closes the top of a previously filled package in mold 76. Thecam 44 is then rocked to release the folding roller 29 adjacent to position a, and the other end of the fresh-carton is thus wrapped about the former tube; this spring-pressed roller 29 remaining in contact-with the tube and carton untilthe latter reaches position. (1,

when the cam again moves to lift it from the tube and hold it away from it until it re- A carton blank is laid over the plates 13 and engaged in the clips been moved to 5 I I i ceives a fresh carton blank. \Vhile the roller folder29 is acting in position a to complete the tube form of the wrapper, the rods 39 are reversed, carrying the several folding devices 5-75803--8592 in an opposite direction, and correspondingly completing the lower end folding of the wrapper at position 7;, and of the filled package at position cl. The spider is then given a quarter turn, and the cycle of operations thus described are repeated; a fresh carton blank being fed to. the machine during each interim of rest of the spider, and a filled package being dis harged from the machine.

it is possible that various changes and modifications may be made in the details of constructionof the present invention withoutldeparting from the principlethereof; and I do not wish to be considered as limiting myself to the detailed arrangement here shown and described.
