WRAPPING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 498,992, dated June 6, 1893. Application filed June 15, 1891. Serial No. 396,345. (No model.)

To aZZ whom it may concern.-

Be it known that I, CHARLES R.SCHILL1NG, of the city of St. Louis and State of Missouri, have invented certain new and useful Improvements in Wrapping-Machines, of which the following is a full, clear, and exact description, reference being had to the accoinpanying drawings, forming a part hereof.

My invention relates to improvements in wrapping machines for wrapping articles of merchandise which are marketed in packages of uniform size; and more particularly in devices for effecting the various necessary folds upon the wrappers, and for discharging the Wrapped packages from the machine.

In the drawings Figure 1 is a side elevation of my complete machine. Fig.2 is a top plan view of the same. Fig.3 is atransverse,vertical, partially sectional view, (the ends being broken away,) of a portion of the machine below the bed-plate, taken on the line rr-cc of Figs. 1 and 6, looking toward the left, showing in section the bed-plate (2) of the machine, the base-plate (18) of the transversely reciprocating carriage; also the side of a vertical rib (19) formed longitudinally on said carriage, with the folders carried thereon and means for actuating the same; also one of the folding-pockets, and other parts. Fig. t is a top plan view of a transversely reciprocating carriage and the mechanism carried thereby. Fig. 5 is a transverse, vertical section (the ends being broken away), through the bedplate 2, on a line y-y of Fig. 6, parallel with the plane of Fig. 3, and looking toward the left, the carriage being removed, and showing the discharge passages 44 in the bedplate, the inner face, toward the rib 19, of a Vertical cam-plate 45 containing the camtracks which actuate the folders on one side of the said rib, and other parts. Figs. 16,17, 18, 19, 20 are vertical sections transverse as to the machine, but longitudinal as to the rib 19, on the line 2-2 of Fig. 6, with the rib 19 as a whole removed, its upper line however being indicated, and also showing one of the folding-pockets formed in said rib and the group of folders carried thereby for operating upon the package while in the pocket,in the various positions which said folders assume during the wrapping operation; also showing the mechanism for discharging the package from the pocket and from the machine. Fig. 7 is a detail perspective view of a portion of the sliding carriage, showing one ofthe two folding pockets therein. Fig. 8 is a detail perspective view of a grooved block (52') hereinafter described. Fig. 9 is a detail perspective view of the post and cap, which support the package in the folding pockets and discharge the same therefrom. Fig.10is

a perspective view of one of the top-folders detached. Fig. 11 is a similar view of an endfolder. Fig. 12 is a perspective view of a package partially wrapped. Fig. 13 is a vertical section of one of the feed-openings in the rotating feeding-disk, and a portion of the plunger. Fig. 14: is a detail view of a portion of the crank and connecting-rod actuating the reciprocating carriage. Fig. 15 represents one of the bottom folders, for making the last fold of thewrapperon the package. Fig.6 is

the machine depends, and the bed-plate 2,

rests upon the upper surface of said table.

3 indicates two supports or hangers which depend from the under side of the base-plate 2, and have in themguiding grooves, 4, which grooves face inwardly, toward each other, and in which the transversely reciprocating carriage 5 freely slides and is supported.

The driving shaft, 6, Figs. 1 and 2, is suitably mounted in bearings, 7, formed in the upper ends of the vertical standards, 8, which rise from the table or frame. Said drivingshaft is mounted transversely to the machine, and parallel with the path of the reciprocating carriage. It carries the usual tight and loose pulleys, 9, also a beveled pinion, 10, which meshes with a gear-wheel, 11, on a shaft, 13, at a right angle to shaft 6. Said shaft 13 is mounted in bearings, 12, secured to the bed-plate 2, and carries a crank, 1 1, which is pivoted to a connecting-rod 15 (Figs. 2 and 14), which extends to a suitable bearing, 16,

formed upon an extension, 17, of the bedplate, 18, (Fig. 4) of the reciprocating carriage. Motion is thus communicated to the reciprocating carriage 5; the gear 11 and the connected parts being of such dimensions that the carriage will travel to the limit of its throw and back to the starting-point but once while the shaft 6 makes two revolutions. The rotation of shaft 6 is in the direction of the arrow in Fig. 1. The end of the connecting-rod 15 is provided with a slot f, (Fig. 14) in which the headed pin g, securing said rod to the crank 14, freely moves, forming a variable pivot, the effect of which is to cause the carriage to make a momentary pause at each end of its throw, while the pin g is passing from one end of said slot to the other.

- The body of the reciprocating carriage 5 consists of abase-plate 18, (Figs. 1 and 4) provided on its upper surface with a vertical rib or flange, 19, preferably integral with the base-plate, which rib extends in a horizontal direction along the center of the carriage. In the upper edge of said rib 19 are formed two approximately rectangular folding cavities, or pockets 20, (Figs. 4, 7, &c.,) which are so located on the rib that by the movement -of the carriage and the other parts of the machine they will be brought alternately, at the properinstant, beneath the feeding plunger andregister therewith.

To accommodate the irregularities of the article to be wrapped and hold it securely while in the pocket, I provide each pocket upon one ormore of its sides, with a spring or clasp, 21, (Fig. 7.) In the center of the bottom of each pocket, passing through said clasp, if of the form shown, is an opening, the same being the upper end of a. vertical passage 22, (Figs. 4,7, &c.,) extending through the rib, in which a post 23, carrying at its top a cap 24, (Fig. 9) is adapted to reciprocate, for the purpose of discharging the partially wrapped package from the pocket at the proper moment.

The folding pockets 20 are located toward the central portion of rib 19. In the outer ends of said rib, as shown in Figs. 3, 4, &c., are formed vertical, longitudinal grooves or channels, 25, cut downward into the rib to a depth about equal to that of one of the pockets. Opening into the channels 25 are vertical passages 26 extending through the rib, in which vertical posts 27 are adapted to reciprocate. Upon the upper end of each of the posts 27 is rigidly secured a push-finger 28, which consists ofa piece of sheet metal bent, into right-angular form, and having its inclosing angle turned .toward the end of the carriage nearest to it. The function of said push-fingers is, when elevated at the proper moment, to push the packages along and out of the discharge-passages 44, as hereinafter described.

'Betweenthe posts 23 and 27, and secured to the under surface of the carriage 5, is a bearing, 29, (Figs. 3, 16, &c.,) in which is and a plunger, 59.

mounted a rocking-lever, 30, (see also Fig. 1) one arm of which is adapted to engage with post 23, to elevate the same at the proper moment, and the other arm to elevate post 27 at the proper moment, and also to depress it by engaging the hook, 31, upon the lower end .of said post 27. It will be observed that the .ends of the rocking-levers 30, which are located under the posts 23 thus elevating the posts 23 and depressing the push-finger 28 at the proper moment. The rocking-levers 30 are rocked back and the push-fingers28 elevated by the descent of the plunger, forcing the article to be wrapped into the folding pocket, as hereinafter described. The arms 88, when released from the operation of the :cam 85, are retracted by springs, 89, interposed between their upper sides and the lower surface of the hangers 3.-

Before describing the folding devices. carried or operated by the reciprocating carriage, I will describe the mechanism by which the articles to be wrapped are fed into the folding-pockets 20. This is accomplished chiefly by an intermittently-rotating feed disk, 54, (Figs. 1, 2, 13, &c.) The feed-disk 54 is circular in form and rotates upon a stationary horizontal bed 57, being interposed between the same and the support, 58, for the plunger. It is pivoted centrally on a bolt, 58. Around its circumference and near its peripheral edge, is regularly arranged a series of feed-pockets, 55, extending vertically through the disk, into which the articles to be wrapped are fed by the operator. Said feed-pockets correspond in size with the folding-pockets of the reciprocating carriage. They are provided with springs or clasps, 56, on their side-walls, as shown in Fig. 13, to adapt them to the irregularities of the article to be wrapped, and hold the same securely until brought under the plunger.

An intermittent rotary motion is imparted to the feed-disk 54, by means of a crank, 78, mounted on the main shaft 6, and pivotally 'connected with one end of an arm 79, which is pivoted at its other end on a sliding plate, 80, in which are formed slots, 82, through which pass screws, 81, secured in the bed-plate '2. Said screws81 hold the plate 80 in contact with the bed-plate 2, but allow said plate to yield to the motion ofthe crank 78, and arm 79, thus establishing a reciprocatinginovementof plate 80 on the bed-plate. Said plate 80 carries a spring pawl, 84, adapted to engage with ITO notches, 83, in the peripheral edge of the feeddisk 54, and rotate the disk a definite distance during the movement of the plate 80in one direction, but to pass said notches and permit the disk to remain stationary during the movement of the plate in the opposite direction. The feed-pockets 55 are thus successively brought over the folding pockets and under the plunger.

The feeding-plunger 59, (Figs. 1 and 2) is located immediately over the feed-openingm in the bed-plate 2, Figs. 6, 16, &c., and is pivoted at its upper end to one arm of a rockinglever, 61, mounted in bearings on a standard, 60. The opposite arm of said rocking-lever extends rearwardly toward the main shafts 6, and carries at its end a roller, 63. A cam, 62, Fig. 2, fixed on the main shaft, engages with said roller 63, and thereby actuates said rocking-lever, thus forcing down the plunger 59 at the propermoment. A coil spring, 71, having one end secured in the base-plate 2, or the table, and its other end in the rearward armof the rocking lever 61, holds the roller 63 in continuous contact with the cam 62, and effects the retraction or elevation of-the plunger after its descent.

The continuous sheet of paper of proper width for forming the wrappers is carried on a reel mounted in supports, 90, at the rear of the machine. A spring, 91, bearing on the projecting end of the reel-shaft, gives the reqnisite tension. The paper is fed into the machine by means of a feed roller, 73, (Figs. 1 and 2) rotating in the same direction as the main shaft, and a smaller friction-roller, 92, located under the roller 73, between which the paper passes. The roller 92 is yieldingly mounted in bearings in the bed-plate 2, the fiat spring, 93, effecting the proper tension. The feed-roller 73 is loosely mounted on a fixed shaft, 72, in bearings within the standard 60, and is intermittently rotated,,to correspond with the motion of the feed-disk 54and plunger 59, by means of an eccentric, 77, on the shaft 6, said eccentric carrying a strap, 77, integral with an arm 77 which extends and is pivoted to a rocking crank, 75, which oscillates on an extension of the shaft 72. Said crank 75 carries a pawl 76, Fig. 2, engaging and actuating intermittently a ratchet-wheel 74, loosely mounted on shaft 72 and connected to and rotating with the feed-roller 73. The operation of the parts is to rotate the feed-roller 73 during the throw of the crank 75 toward the main shaft, and to permit said roller to remain stationary during the throw of said crank in the opposite direction. A spring stop 74, Fig. 1, prevents the ratchet wheel 74 and feed-roller 73 from rotating in the wrong direction during the throw of the crank 75 away from the main shaft. The paper is cut into proper lengths to form the wrappers by means of a knife, 66, Fig. 1, movably mounted on a vertical guide, 67, in front of the feed-roller 73, and near the feed opening m. Said knife is actuated vertically by a rocking-frame, 65, Figs. 1 and 2, of rightangled form in cross-section, pivoted at its angle on abearing, 64, in the standard 60. It carries in the end of its upright arm a roller, 70, which engages with the cam 62, on shaft 6, which cam also actuates rocking-lever 61, as before mentioned. The revolution of said cam 62 causes the knife 66 to descend and cut off the wrapper. The knife is retracted after operating by means of a spring shown in Fig. 1.

When by the operation of the feed-mechanism the free end of the paper is brought over the rectangular opening m in the bedplate 2 and under the plunger 59, the knife 66 descends and cuts it off. At the same time one of the feed-openings 55 in the feed-disk 54, containing a cake of the material to be wrapped, is brought over said wrapper covering said opening m, and under the plunger. At the same time also one of the folding pockets 20, by the movement of the carriage 5, is brought under said opening m and the plunger; the carriage making a momentary pause, owing to the operation of the crank 14 and slotted connecting-rod 15, (Fig. 14) as hereinbeforedescribed. Theplunger nowdescends, pushing the cake of material downward out of the feed-opening 55, and forcing it, together with the Wrapper under it, through the opening an into the pocket 20; the sides of the wrapperfolding upagainst the sides of the cake, as shown in Fig. 16. It may here be said that the plunger operates upon one of the folding-pockets during the pause made by the carriage at one end of its throw, and upon the other pocket in the pause of said carriage at the other end of its throw, the two pockets and their associated mechanisms being operated alternately.

Having described parts of the machine the action of which is preliminary or secondary to that of the folding devices carried or operated by the reciprocatingcarriage, it remains to describe said folding devices. These consist of top-folders, for making the first and second folds over the top of the package, tuckers for tucking or pressing down the ends of the wrapper from above, preliminaryto the end folds, end-folders for turning in the end flaps from each side, and bottom-folders for turning the final flap under the package. It is to be observed that, it having been found convenient and economical to provide each machine with two folding-pockets, there are also in each machine two separate, independent sets of folding and also of discharging devices, one set for each pocket, all carried. or operated by the reciprocating carriage; one set operating during the stroke of the carriage in one direction, and the other set during the stroke in the opposite direction. 1

In Fig. 10, 32 represents a top-folder in detail. It consists of an elastic blade, y, of sheet metal, of rectangular form, to one end of which are rigidly attached depending wings n, at, one on each side, in which are formed rivet-holes h, h, adapting them to be secured on rivets passing through the holes 4', 2', in the rib 19, (Fig. 7,) near the folding-pocket 20. A rocking motion is thus permitted to the folders on the pivots t, 6, over the adjacent folding pocket. There are two top-folders, 32 and 32, for each pocket, so that their folding-blades face each other from opposite sides of the pocket. Each top-folder 32 carries a lug 47, and each top-foldder 32 a lug 48, by which each of said folders is actuated.

Fig. 11 represents an end-folder, 33 or 36, in detail. Each pocket has two, one upon each side. Each consists of two arms or blades, one having a downward extension 0, both rigidly secured on a rivet or axis 70, adapted to pass through holes Z, Z, in the rib 19. A rocking motion is thus permitted to said folders, when actuated, upon the axis 70, across both the open ends of the pockets, upon each side of rib 19. The form of the end-folders upon one side of the pocket is the reverse of that upon the other side. Each end-folder 33 carries alug, 52, for'actuating the same. Each end-folder 36 is pivoted at 36' to one end of a sickle-shaped lever, 35, which is pivoted at 34 to rib 19, and carries at its farther endalug, 50.

As shown in Figs. 4 and 16 to 20, the vertical wings of top-

folders

32 and 32 lie close to the lateral surface of rib 19, or in movable contact therewith, on each side of said rib. The

folders

36 and 33 lie over or outside of 32 and 32' respectively, and the levers 35, which actuate folders 36, lie outside of all the folders and next to the cam-plates 4'5, The

lugs

47, 48, 50, 52, on the various folders and the lever 35 extend outwardly far enough to enter the actuating grooves in the adjacent ers are actuated. will now be described. The

two cam-track-plates, 45 and 45', (Figs. 1, 3, 4, 5, 6, and 16 to20) depend from and are firmly secured to, the base-plate 2, one upon each side of the rib 19, and parallel and closely contiguous thereto. They are flat, rectangular in section, and extend across the machine from side to side. In their inward faces, toward the rib 19, are formed cam-grooves or tracks, 46, 49, 51, into one of which the

lugs

47, 48, 52 and 50 project, and in which they move during each throw of the carriage, imparting the desired motion to the top and end folders as hereinafter more specifically stated.

The description of the relation and operation of the folders, lugs, and cam-tracks will refer mainly to those for one pocket, it being understood that the same devices and arrangement'are duplicated at the other end of the carriage, for the other pocket, though the position of said parts, as to the side of the rib 19 occupied by them, is for greater convenience reversed for the respective pockets, as shown in Fig. 4.

Figs. 3 and 16 to 20 illustrate mainly the parts grouped about or auxiliary to the operaends, near their pivotal points.

tion of the folding-pocket which is at the rear end of the carriage. The cam-plate shown in full lines is 45, on the left of rib 19, Fig. 1, except that in Fig. 3, where the rib 19 is interposed, the cam-tracks in plate 45', lying behind it, are shown in dotted lines and a sectional fragment of plate 45, on the right of rib19, is introduced in full lines to show the track 49, in said plate. Whenever necessary to show the operation of the folders the tracks in the plate opposite to the one' shown in full lines appear in dotted lines. In all said fig ures the motion of the carriage, with its appendages, is supposed. to be from left to right.

The article to be wrapped and its wrapper having been deposited in the pocket 20, as before described, (Fig. 16) the carriage, moving to the right, carries lug 47., on top-folder 32, up the adjacent curve in track 46, tilting folder 32 and causing its blade to pass over the pocket, andmake the first topfold. (Fig. 17. See also a, Fig. 12.) The continued movement of thecarriage-carries lug 47 down said curve, retracting folder 32. .At the same time lug 48, on top-folder 32, moves up the curve adjacent to it in said track 46, tilting said folder and making the second top fold in a similar manner. (Fig. 18. And b, Fig. 12. The projecting ends of the wrapper are then operated on by the tuckers, (Figs. 1, 4, 5, and 6.) Said tuckers are attached to the reciprocating carriage 5, and are four in number, one upon each side of each pocket. Upon the bedplate 18 of thecarriage are mounted standards, 39, in a mortise in the upper corner of the outer face of which, at a right angle-to rib 19, are pivoted, at 3, vs, short arms, 40, having heads 38,and crank extensions at their lower Alsoon said blocks 39 are pivoted at t,t, levers 41, one-end of which is slotted to receive lugs gap, on the crank extensions of the arms 40. A yielding pivotal connection is thus established between the arms 40 and levers 41, which is assisted by springs, 43, connecting the lugs p, p, with screws or studs, r, r, on levers 41. The opposite ends of levers 41 extend laterally beyond the face of the standards, 39, and carry rollers, 42, mounted thereon longitudinally. Said rollers are adapted and arranged, when moved with the carriage, to enter and traverse inverted-V-shaped grooves, 53, formed in the faces of blocks 52', (Figs. 1, 5, 8, 6) which are secured on or formed in the inward sides of the hangers 3. In Fig. 1 said rollers are seen about to enter the grooves 53; in Figs. 8 and 6 they are represented as passing through them. When the rollers 42 enter the grooves 53 the motion of the carriage causes each of them to follow the upward, andafterward the downward, curve of its groove, thus first quickly depressing the slotted ends'of levers 41, also the arms 40 and heads 38, throwing the latter into horizontal position and then elevating them again to their normal vertical position, as in Fig. 1. The effect of IIO the descent of the tucker-heads 38 near the ends of the pockets is to press down the upper folds, c, (Fig. 12) of the wrapper over the ends of the package and between the still unfolded lateral flaps, d, e. As the

camplates

45, 45, are interposed between the tuckers and the pockets 20, on each side, an opening to, Figs. 5 and 6, is provided in each of said plates, .through which the tuckerheads are adapted to pass to operate upon the package. Said openings are wide enough and the movement of the tuckers quick enough to admit of this operation while the carriage is in motion. After the tuckers the end-

folders

33, 36, are operated. The lug 50, on one end of the lever 35, (Fig. 19) the carriage still moving to the right, is carried down the adjacent curve in track 51, rocking said lever onits pivot or fulcrum, 34, and operating end-folder 36, to which the other end of said lever is pivoted, by causing the blades of said folder 36 to pass across the ends of the package, turning in the flaps d, (Fig. 12.) The lug then moving up the curve in track 51, lever 35 returns to its normal'position,and folder 36 is retracted. Meanwhile the remaining end-folder 33 is operated by lug 52, on the opposite side of rib 19, moving up the curve in track 49, in the opposite track-plate 15, (Figs. 3 and 20) causing the blades of folder 33 to pass across the ends of the package and turn in the flaps e Said folder 33 remains in the position occupied at the completion of the fold made by it until the carriage reaches the end of its throw and during the pause of the carriage and the ejection of the partially wrapped package from the pocket, as hereinafter described; and said folderis retracted to its normal position, as in Fig.16,by the movement of the carriage in the opposite direction causing lug 52 to move down the curve in track 49. Referring to Figs. 4; and 16 to 20, it is to be noted that lug 47, operating top-folder 32, also lug 4.8, operating top-folder 32, together with their common track, 46; also lug 50 on lever 35, and its track, 51, actuating end-folder 36, are all on one side of rib 19 and at one end of the pocket; while lug 52 and its track 4.9,operating end-folder 33, are on the opposite side of the rib and at the other end of the pocket. The wrapping being now completed, as seen in Fig. 20, except the folding under of the lower flaps at each end, the package" is next elevated out of the pocket into the passage 14, wherein the final fold is effected, and through which the package is discharged from the machine. Said passagee t, (Figs. 1, 5,and 16 to 20,) consists of an elongated slot, rectangular in cross-section, formed in or cut vertically through the bed plate 2, directly over and parallel with the rib 19, and of suitable dimensions to accommodate the wrapped package. If the carriage, as usual, has two folding-pockets, there are two such passages, one for each pocket. They extend from a point near the feed-opening m, under the plunger, outwardly to the edge of the bedplate, upon each side. Said passages are closed at the top by covers 14:. They are open at the bottom over the paths traversed by the push-fingers 28, Figs. 16 to 20, but thence outwardly to the discharge-opening are provided with a bottom or floor 'v, 1;, (Figs. 15, 20,) the inner end of which, 10,20, is V-shaped and beveled, (Fig. 15) having its open angle facing inwardly toward the push-finger. Said V-shaped section will be designated as the folder to. When the carriage stops at the end of its throw the folders, post 23 and push-finger 28 will remain in the position shown in Fig. 20, but the pocket, containing the package, will be a little farther to the right than shown in said figure, and about under the inner end of passage 44. During the pause of the carriage one of the arms 88, Figs. 1, 16, actuated by lever 86 and cam 85, impinges upon one end of rocking-lever 30 and elevates post 23, carrying the package out of the pocket and into passage44, nearits innerend, where the package is for a time held in suspension by frictional contact with the sides of the passage. The push-finger 28 is depressed by the lever 30 at the same time that post 23 is elevated. The carriage now moves to the left until it reaches the end of its throw in the opposite direction, bringing the pocket in question again under the feedopening m, as in Fig. 3. The plunger then descends, forcing another cake of the material into the pocket, depressing post 23 and elevating push-finger 28, as in Fig. 16. The vertical blade of the push-finger in rising passes between the package held in suspension and the inner end of passage 14, while its horizontal blade comes underneath the package, in position to support it. The carriage now moves again to the right, thus pushing the package outwardly along the passage and partly over the folder w, Fig. 5, lodging it thereon and leaving it there. The next return of the carriage brings another package, which impinges on the previous package, forces it over the folder w, and on toward the outlet. The efiect upon the lower end flaps of being thus brought in contact with the beveled folder to is to turn said flaps inward under the package, thus completing the wrapping process.

The parts are so adjusted and their movements so timed that, when the machine is in full operation, one pocket is being filled by the operation of the plunger 59 while the other pocket is being emptied by the operation of one of the posts 23; and with each throw of the carriage in either direction a fully wrapped package is discharged from the corresponding outlet.

It is obvious that numerous changes might be made in the form or arrangement of the parts of the machine without departing from the essential features of my invention. For example, the reciprocating carriage may be mounted in suitable guides resting directly on the floor, instead of in hangers depending from the bed-plate. made in various parts with a view to securing greater lightness, economy of construction, or other advantages. I do not therefore limit my claims to the exact details of form or arrangement shown.

I claim as my invention and desire to secure by Letters Patent 1. A Wrapping-machine having a reciproeating carriage formed with a pocket for receiving the article to be Wrapped and its wrapper, said pocket being provided with a yielding wall and bottom, substantially as described.
