MACHINERY FOR SECURING WRAPPERS OR LABELS AROUND BOXES, CAKES, &'c.

SPECIFICATION forming part of Letters Patent No. 522,723, dated July 10, 1894.

Application filed June 20,1889.

To all whom it may concern.-

Be it known that I, ALBERT STEARNS, a citizen of the United States, residing in the city of Brooklyn, in the county of Kings and State of New York, have invented a new and usef 111 Improvement in Machinery for Wrapping and Securing Wrappers or Labels Around Boxes, Cakes, Packages, or other Articles of Merchandise, of which the following is afull, clear, and exact specification, reference being had to the accompanying drawings.

This invention is intended for applying wrappers to boxes, cakes, packages or other articles of parallelopiped, prismatic or other approximate form in such manner as to inclose them completely by the wrapper being first wrapped around the sides of the boxes, cakes, packages or other article and afterward folded and turned over the ends thereof.

The invention also provides for pasting or applying adhesive material to such parts of the edges and folds as may be necessary to secure the wrapper in a closed condition.

To enable others skilled in the art to make and use my invention I will first explain in a general way the figures of the accompanying drawings which represent a machine embodying the whole of my invention and illustrate the process performed by said machine. I will next briefly explain the several acts which constitute the operation of the said machine, referring briefly to some of the principal parts of the machine itself. I'will afterward describe the construction and operation of the machine in detail and I will finally point out the novelty of my invention in claims.

' Figure 1 of the drawings represents aplan of the machine. Fig. 2 represents a longitudinal vertical section taken in about the plane indicated by the line 1, 1, in Fig. 1, Fig. 2* represents an end view of the package and wrapper with back view of the side tuckers on one side of the machine. Fig. 2** is a side view of the curb in which what is called the receiving-wheel works. Fig. 3 is a longitudinal vertical section taken in about the Serial No. 814,931. (No model.)

partly in section representing in diiferent po: sitions certain details which are only imperfectly shown in Fig. 4. Fig. 8 isa horizontal sectional view taken immediately below the upper stationary table of the machine. Fig. 9 is an elevation of that end of the machine which appears at the right hand of Figs. 1, 2, 3, 4, and 8. Fig. 10 represents an elevation of that end of the machine which appears at the left hand of Figs. 1, 2, 3, 4 and 8, but shows the delivery table of the machine in section. Fig. 11 represents a longitudinal section corresponding with Fig. 3 but showing the parts in a different position. Fig. 12 is a plan corresponding with Fig. 11. Fig. 13 represents a transverse section corresponding with Figs.

11 and 12 in the line 4, 4, of those figures. Fig. 14 represents a transverse sectional view of some of the parts of the machine in the ob- 7o lique line '5, 5, shown in Fig. 2. Figs. 15, 16, 17, 18, 19 and 20 are perspective views of a package and wrapper illustrating the work performed by the machine... Figs. 21 to 28 inclusive are separate profile views of some of the cams which are not distinctly visible in the figures representing the machine. Fig. 29 represents a horizontal sectional view of part of the carrying wheel and of the pressing-dies for flattening and gluing the end flaps. Fig. 30 isa front view of the..pressingdie and glue-die. Fig. 31 represents a plan view of part of the mechanism for operating what is called the row-dresser.

Figs. 1, 2, 3, 4, 8, 9 and 10 and the figures of the cams are on one scale and the other figures are on a larger scale.

Similar letters of reference designate corresponding parts In all the figures.

The several acts which constitute the oper o which has an intermittent rotary motion, has in its periphery a series of pockets open at the sides. The wrappers are supplied to the said wheel from a pile or box in front thereof and the packages or articles to be wrapped are supplied thereto from the rear thereof. The rear edge of the wrapper is pasted by a paste-die while in the pile or box and lifted by the said die from the pile to be delivered to the grippers of what I term a wrapperplacer which carries the wrapper to the position over the top of the receiving-wheel while the latter is at. rest. One of the packages or other articles to be wrapped is then brought by what I term a package-feeder over the wrapper which is then liberated from the wrapper-placer and the box is pushed down into one of the pockets of the receiving-wheel by what I call the package-placer, carrying the wrapper with it and soplacing the wrapper against three of its sides or its bottom and two of its sides as shown in Fig. 15 of the drawings in which A designates the wrapper and B the package. A folding blade carried by a lever pivoted on the shaft of the receiving-wheel then turns one edge a of the wrapper over the top of the package and over this edge a the pasted edge a is turned by the return of the wrapper placer. Thewrapper is now wrapped around four sides of the package or article and there secured by paste.

- The receiving-wheel then turns far enough to bring the package and wrapper between what I call top tuckers and side tuckers and stops there while all the said tuckers operate. The top tuckers turn the edges a of the wrapper over the ends of the package or article as shown in Fig. 17, and at the same time form the side tucks a a and the side tuckers turn in first, as shown in Fig. 18, one of the side tucks a and afterward as shown in Fig. 19, the other of the said side tucks a. By the act of turning in these tucks a ,a the flaps a.*, (see Figs. 17 and 18) are folded diagonally as shown at a and a*, (see Figs. 18 and 19) to form the bottom tuck a and the sharp creases a, are formed between the side and bottom tucks. After the said side'tuckers have done their work, the said wheel moves again and carries the folded and tucked portions a afla, of the wrapper between gluedies from which 'the said port-ions receive a suitable quantity of glue or strong adhesive material.

' The receiving-wheel moves to and stops between what I call bottom tuck closers which turn in the glued bottom end tucks a over the turned in side tucks a a and so completes the wrapping. The wheel then carries the wrapped package or article to a table whereon it is delivered and placed in rows to be removed for storage or transportation.

I will now proceed to describe the machine in detail.

O O C designate an uprightframing oh the top of which is supported a horizontal table D, and in the sides of which at some distance bers of the machine.

below the said table are firmly secured the ends of the stationary horizontal shaft E, upon which the receiving-wheel E is fitted to rotate. The upper part of this wheel projects into an opening d in said table and to a level with theupper surface of the latter as shown in Fig. 3. The said table will be hereinafter spoken of as the receiving-table to distinguish it from a lower stationary table F, which I term the delivery-table and which is shown at the left hand of Figs. 1, 2, 3 and 8, supported upon brackets F, secured to the main framing at that end of the machine which is to the left hand of those figures. The said delivery-table is also shown in section in Fig. 10.

The opening cl, before mentioned in the receiving-table D is of awidth, taken in the direction crosswise of the table and parallel with the shaft E, slightly greater than the width of the wrappers which are to be applied in the machine and of a length sufficient to expose through it a considerable portion of the upper part of the Wheel and to allow the passage within it of a box G, in which a number of wrappers g, are placed one upon another.

The receiving-wheel E is of a width across its face equal to the length of the package to be wrapped and hence considerable less than that of the opening cl in the table. The said wheel, the construction of which is best shown in Figs. 3 and 14, consists of a cylindrical drum connected by arms with a hub which is fitted to turn on the shaft E, and has on the outside of the said drum a series of horns e, which form skeleton pockets 6 for the reception of the packages to be wrapped and the wrappers, the said pockets being of a width and depth corresponding with the width and thickness of the packages. The pockets 0' are equally spaced around the circu inference of the wheel. Their exact number is not material. In the example represented, the wheel has eight pockets. To provide for the intermittent rotation of the said wheel, it is furnished internally near one side with a series of ratchet teeth e shown in Figs. 3 and 14 to be engaged by a hooked pawl 6 carried by a lever E which works on a fulcrum 6 near the bottom of the machine. To this lever is connected one end of a rod 6 the other end of whichis supported by a rocker e pivoted at e to the framing and the said rod carries an anti-friction roller 6 which works in a groove of a cam E on a shaft S, which also carries several other cams to be hereinafter described for operating. the different mem- By the operation of this cam on the roller 6 the rod 6 is caused to operate the hooked-pawl a engaging with the ratchet teeth 6 and the carrying-wheel is caused to make an eighth of a revolution and then to stop for some time during each revolution of the cam shaft S so that one of the pockets of the carrying wheel will be presented upward within the opening cl of the table as shown in Fig. 3 and held there for some time during each revolution of the said cam shaft and cam.

To provide for locking the receiving wheel every time it arrives in the position above mentioned, there are provided in one side of the said wheel aseries of holes, or stop notches 6 corresponding in number with the pockets 7 and arranged at equaldistances apart in a circle concentric to the wheel and one of which, when the wheel is in such position, is engaged by a stop 6 which projects from the face of a bar E which is suspended at its upper end by a hinge from the receiving-table D and to whicha spring 6* shown dotted in Fig. 4 is applied to press it toward the wheel. This bar E is pushed aside to withdraw the stop 6 from the wheel and unlock it before each new movement of the wheel to present a new pocket through the opening in the table D, by means of a little switch consisting of a lever e which is pivoted on the rod 6 as shown in Figs. 5, 6, and 7, which are plan views showing the parts above referred to in different positions. The said. switch lever, c has applied to it a spring e which holds it against a stop on the rod 6 In order to effect this unlocking, the rod e and the pawl e have a longer motion than is necessary for the movement of the receiving-wheel, the pawl being thus made to pass beyond the teeth c of the ratchet-wheel a considerable distance as shown in Fig. 3 before returning to take hold of the teeth to turn the wheel.

'As the said rod e returns and before it engages a ratchet tooth, its movement being then in the direction of the arrows in Figs. 5 and 6, it brings one end of the switch lever between the bar E and the wheel, and as the rod e moves on it presses aside the said bar and so withdraws the stop 6 from the hole 6 in the wheel to leave the latter free to be moved by the pawl as the last mentioned movement of the rod c is further continued.

This movement is continued until the switch lever passes by the bar E so that as the rod e returns the switch lever passes as shown in Fig. 7 outside of the bar e which has resumed its position to produce the engagement of its stop 6 with the wheel. In order to prevent the wheel from being carried by its momentum after the action of the pawl e ceases, beyond the position for the pin e to lock it, there is applied to it a friction brake on one end of a lever G (see Fig. 10) by a rod G which works in the guideD fixed under the receiving-table D. The said guide also contains another. These weights are not entirelysuspended from the said lever but one end of the pile restson a fixed supporting table G and the other end of the lowest one of the pile always hangs on a nut g on a rod 9 dependent from the lever. On the table G is a series of steps 9 (see Fig. 4) corresponding with the number of plates or weights 9 and in the said platesare holes, one in each, the hole in the lowest one being long enough to take in all the steps, the one in the next above being long enough to take in all the steps but one, and so on, the hole in the topmost plate being only long enough to take in the top step. When the box G, is full of wrapper sheets the weight of the said sheets causes the lever G to lift all the weights from the table G and its steps but as the wrapping sheets are taken from the box and the box and its contents become lighter the other end of the lever is depressed by the weightsand the box is raised. As this goes on the weights severally and successively drop on the steps immediately below them and their load is taken from the lever, and in this way the box and the wrapper sheets are always counterbalanced and the top sheet in the box is kept at about the level of the top of the receiving-table as shown in Fig. 3.

H (Figs. 2, 3 and 10) designates the paste die by which paste is taken from a roller I (shown best in Fig. 3) and deposited on the top sheet 9 in the box G close to that edge which is toward the receiving-wheel, that is to say the edge of the sheet which is marked a in Fig. 15. The roller I works in a stationary paste trough I which is supported in a small stand 1* on the table G. The pastedie consists of a rod which is broadened at its lower end and which may have a straight fiat lower face but is represented (see Fig. 10) as having a series of flattened points on which the paste is taken from the roller and by which the paste so taken is deposited on the sheet in a series of small patches. The upper end of the rod of the die works in the fixed guide II, which permits it to have a longitudinal reciprocating movement and to swing be tweenthe paste roller I and the box G. At some distance below the said guide, the said rod. is suspended by a short link h from a lever H which works on a fulcrum h,in a post H erected on the table D. Between the said link hand the fulcrum, the said lever has connected with it a rod 72, which works through a guide standard 11 and passes through the table D. At the lower end of this rod h, isa roller h which works in a groove on a cam H on the shaft S, shown best in Fig. 2,which operates on the said roller 7r", rod 7L and lever H to produce. an upward and downward movement of the paste die. The lever H is furnished with an adjustable counterbalance H to counterbalance the weight of the paste die H and of the rod 7%.

Besides the upward and downward movement hereinabove described as given to the paste-die, the said die has a swinging movement which with the said upward and downward movements enables it to take the paste from the roller I and deposit it on the wrapper sheet. I will now describe the means of producing this swinging movement.

I designates a cross-head (Figs. 1, 2 and 3) which I term the paste-die shifter and which .slides on two small fixed horizontal guide-rods 71 secured to the standard of the guide H; The

rod of the paste die passes through this crosshead and the reciprocating motion given to the said cross-head on the said guide-rods produces a swinging movement of the paste-die. This reciprocating motion of the cross-head, which is transverse to the longitudinal reciprocating movement of the paste die H, is produced by an arm 11 (see Figs. 1, 2, 3, 4, and 10) on a horizontal rock-shaft I which works in hearings in standards I erected on the table D. The said rock-shaft derives rocking movement to operate the cross-head I from a cam I on the rock-shaft S. This cam is shown in profile in Fig. 21 with a part of the lever upon which it operates. The said lever and all its connections with the rock-shaft are shown in Fig. 4. The said cam operates upon the rock-shaft throughalever 1 which works on a fixed fulcrum i and which is connected by a rod 1 with an arm I upon the rockshaft. The joint action of the camsHiand I on the paste-die is first to raise the die, then swing it toward the paste-roller I, and press it against said roller to take paste therefrom, then swing it back to a position over the sheets in the box, G, then depress it upon the top sheet, afterward to rise a short distance and then stop. In this last mentioned part of the operation, the die by means of the adhesion "of the sheet to it from the paste, picks up the front edge of the sheet a little way from the pile to permit it to be taken hold of by what I call the wrapper-placer which has been referred to in the introductory portion of this specification and which I will presently describe.

In order that the carrying-wheel and other partsof the machine may be kept in-operation for the delivery of any boxes remaining in the machine without operating the pastedie-shifter I which would thus be not only unnecessary but objectionable, the arm I of the rock-shaftis fitted loosely to the said shaft and capable of being thrown into gear therewith and out of gear therefrom by means of a clutch I operated by a lever I and rod 1 the said clutch being capable of sliding upon the rock-shaft to engage and disengage the hub of the arm 1 but being compelled to turn with the said shaft. As there is nothing peculiar about the method of throwing the arm 1 into and out of gear any further description of it is unnecessary.

For the purpose of turning the paste-roller I in the trough I to keep its surface constantly supplied with paste, there is provided on the shaft of the said rolleraratchet-wheel i (see Fig. 4) which is turned by a pawl i of the rock-shaft which operates the crosshead I I will now describe the wrapperplacer which takes the wrapper sheet from the pastedie H, after it has been lifted by the latter as hereinbefore described, and places it over the uppermost pocket 6' of the receivingwheel. This placer consists of a pair of grippers J, 7', (see Figs. 3, 11, 12 and 13.) The lower part of these grippers consists of a plate or carriage J which is fitted to slide in fixed horizontal guides J arranged upon the table D on opposite sides of the opening d. The

wheel E, is produced through a rod J, lever J and rod J by a cam J, as best shown in Fig. 3, but partly shown in Fig. 11. The rod J is connected with the upper end of the lever J which is fulcrumed at its lower end on a fixed-fulcrum j and has connected with it one end of the rod J the other end of which is furnished with an anti-friction-roller J running in a groove in the cam J The rod J 3 is supported by a rocker J (see Fig. 3) working on a fixed pivot j in the framing of the machine. Besides the spring 7' for closing them, the grippers are furnished with a hooked-catch j (see Figs. 3 and 11) which is pivoted to the plate J, and which is connected by a spring 3' which is suitably applied between it and the said plate for the purpose of throwing its hook over one of the bars j of the upper gripper member as shown in Fig. 3 for the purpose of holding the grippers open. At a distance beyond the opening d, in the table there are placed upon the table two stationary plates which constitute gripperopeners J the said plates having inclined projections as shown in Figs. 2,3 and 11. As the grippers run from the wrapper box G, over and beyond the receiving-cylinder, the projections j on the upper member of the grippers run under these gripper-openers J 6 andthe grippers are thereby opened. The hooked catch j isthen drawn by the spring j over its respective cross-barj' of its member and the grippers are thereby held in an open condition while they are returning toward the box G to fetch a wrapper-sheet and as they arrive at the position over the edge of the box G in which they receive within them the edge of the sheet raised by the. paste die H, the hooked-catch 9' strikesa fixed stop j under the paste-trough stand as shown in Fig. 11, and is thereby thrown olT the crossbar j leaving the grippers free to be closed edge, the spaces between the points allowing duces the operation of the package-feeder by room for the fingers of the upper gripper J to pass through the said die.

K designates the package -feeder. This consists of a plate which is fitted to slide within horizontal guides K supported on small standards K on the table D, and on this plate is secured a second plate 70 of a size and form corresponding with that of one of the sides of the package 13 to which the wrapper is to be applied. This plate 70 is made with or has attached toit corner pieces 7t, 7t,to receive within them and hold a package. To the plate K is connected by ahinged joint 10 a rod K in which is a slot 70 which receives an upward projection k provided on the rod J which operates the wrapper placer. The movement of the rod J back and forth proits coming in contact with the ends of the slot k but gives the package-placer a shorter movement than that of the wrapper-placer. In completing the movement of thewrapperplacer from the box Gover the receiving-cylinder, the projection 70 striking the end of the slot which is toward the right, brings the package-feeder to a position to where the package B, may be deposited on the part it of the wrapper-placer within the corner-pieces by an attendant conveniently stationed for the purpose. When the wrapper'placer returnstoward the box G for a new wrappersheet, the projection k coming in contact with the left hand end of the slot 76 in the rod K picks up the package from the feeder K to place it in the pocket of the cylinder after the feeder K has again moved to the right. In order to prevent the package feeder from being carried too far by the momentum which itacquires when the left hand end of the slide 70 is moved by the projection 76 it is provided with stop projections k which are arrested by fixed stops 70 provided on the guides K.

The package-placer L L consists of a plunger or block L and a box L open at the top and bottom within which the said block is snugly fitted, the said block conforming substantially in its horizontal section to the shape of the box to be wrapped. The box L is furnished with rods Z united at the top by a cross-head Z working in upright guides L carried by standards L erected on the table D. The position of these standards and guides is such that the package-placer L L is always directly over the position occupied by the uppermost pocket e of the receivingcylinder. The block L has firmly secured to it upright rods Z which pass through lugs Z provided on the box L and overlapping the block, the said rods also passing through latcrally-extending lugs Z provided on the rods Z. The said rods Z are provided with collars or shoulders Z between which and the lugs Z on the box L coil-springs Z are placed upon the said rods. the block L within the box L and against the lugs Z on the latter, the lower face of the block L then being nearly flush with the face of the box. To the outside of the box L are attached spring-elastic-grippers Z which project below the said box for the purpose of taking hold of the package placed by the package-feeder as shown in Figs. 11 and 13. There are also rigidly attached to the sides of the box L wing pieces Z which project laterally far enough to come in contact with the fixed-guides K of the package-feeder when the box is depressed sufficiently as will b hereinafter explained.

The package-placer is operated through a a rod L by which the box L is suspended from a lever L the said lever being supported on a fulcrum Z in a post L erected upon the table D, and being connected by a These springs tend to hold up rod L with a cam L on the cam shaft S. A

side view of this cam is given in Fig. 22, and an edge view in Fig. 10. The rod L and all the connections between it and the rod L are shown in Figs. 3 and i and parts of these connections are also shown in Figs. 9 and 10. The rod L passes through the table D and a guide L erected thereon. The lever L is furnished with an adjustablecounterbalance L for the purpose of balancing the weight of the package-placer and rod L The operations of the package-placer pro duced by the cam L are as follows: The first operation is that of taking a package B from the package feeder K. To do this the package-placer descends bodily, that is to say, the block L and the frame L descend together, the block L being depressed by the lever L and rod L carrying the box L with it by the pressure of the springs Z upon the lugs 1 This descent brings the grippers Z over the sides of the package B as shown inFigs. 11 and 13 and is continued until the lower face of the block is in contact or nearly so with the top of the package. the package with sufficient firmness to pick The grippers Znow hold it up on the ascentof the package-placer which immediately follows. While the packageplacer is thus raised the wrapper-placer brings a wrapper-sheet over the pocket of the cylinder which is stationary under the packageplacer and takes the package-feeder out of the way and after that hasbeen done the packageplacer again descends bodily as before but is continued much farther, the box L descending until it is arrested by its wing pieces Z coming in contact with the guides K of the package-feeder, and the block being carried down still farther to push the package out of the grippers Z and push it and the wrapper sheet with it into the pocket e of the cylinder.

By the above described operation of the package-placer, the back and front ends a a, of the wrapper are turned up over the sides of the package as shown in Fig. 15. The lever M (see Figs. 3 and 4) which carries the folder consisting of a blade m (see Figs. 3, i and 8) for turning in the edge a, (see Fig. 15) of the wrapper is pivoted loosely upon the cylinder shaft F. at a short distance from one side of the cylinder. The said blade may be flat or arc-formed to conform to a circle circumscribing the outside of the wheel, that is to say, the points of the horns e. It projects laterally from the lever M and is as long as the wrapper is wide and consequently extends all across the face of the cylinder and somedistance on each side thereof. Its operating edge, that is to say, the edge presented to the right hand in Figs. 3, 4t and 8 of the drawings, is forked as shown in Fig.8 to pass between the patches of paste which have been applied to the wrapper by the paste-die and so avoid taking up any paste from the wrapper. The said lever after the package and the label have been placed in the pocket of the receivingwheel and brought to the condition, as shown in Fig. 15 as just described, sweeps over the pocket and in so doing turns the edge a, over to the position shown in Fig. 16, stopping for a short time after said movement. The movement of the said lever is produced by a cam M on the shaft S, acting through a rod M connected at m with the lower end of the lever, the said rod having at one end a roller m which runs in a groove of the cam and its other end which is prolonged some distance beyond the connection m working through a fixed guide M on the framing.

To provide for the turning of the pasted edge a over the edge a of the wrapper, as shown in Fig. 16, there is provided on the Wrapper-placer J, j, a folder consisting of a transversely-arranged horizontal roller N (see Figs. 3, 11 and 13). The shaft or journals of this roller are supported in lugs non the plate J just beyond that end of the plate which constitutes the lower member of the grippers. As the wrapper-placer moves forward with the wrapper this roller has nothing to do, but on the return of the wrapper-placer which takes place after the deposit of the package and the wrapper in the wheel by the packageplacer and the subsequent movement of the folding blade m which has just been described, the said roller encounters the turned-up portion of the .wrapper having the pasted edge a, and as the roller passes over the package it turns the said edge over the edge a to the position shown in Fig. 16, the blade on having remained over the turned-over edge a, until the edge a has been turned over far enough to prevent the said edge a from rising. The roller passing over the edge a presses the pastedortion of it down upon the portion of the wrapper below it and so secures the edge a, in the position in which it is shown in Fig. 16. As the roller N moves over the edge a to turn it over, the folding blade m returns while the cylinder remains stationary.

I will now describe the top tuckers which turn in the edges a of the wrapper over the ends of the package, as shown in Fig.17, and at the same time form the side tucks a a. These tuckers consist of two very thin plates 19, the form of the face of which is very clearly shown in Fig. 4. The loweror operative portions of these plates are rectangular'as shown in the last mentioned figure, and of a width very slightly less than the width of the pockets e of the receiving-wheel, and they are so situated that they may, as shown in Fig. 3, come opposite the open ends of the pocket containing the wrapper and the package, when the wheel has moved such adistance as to bring a new pocket to the uppermost position in which the turning up and turning over of the edges a, a of the wrapper are performed, such distance in the example represented being one-eighth of a revolution. The two plates constituting the tuckers are arranged in vertical planes parallel with the planes of rotation of the wheel with their inner faces flush with the sides of the wheel, and are carried by two heavier sliding-plates p, represented of triangular form in Fig. 3, which are fitted to slide in stationary inclined ways 19 (see Fig. 8) secured to ahorizontal plate P, (see Fig. 3) which is bolted to the bottom of the table D. The tuckers p are arranged on the outer faces" of the said plates cf and are secured thereto by any suitable means. In Fig. 3 there are plainly visible three screws which serve the purpose of securing the tuckers. Opposite to the top tuckers p, and extending some distance above and below them, as shown in Fig. 4, there are two stationary sector-shaped plates W, the arcs of which conform to the periphery of the cylindrical portion of the receiving wheel E. These plates are also shown in Fig. 8, and are close to the cylinder. Their thickness is equal to the width of the portions of the wrapper which project beyond the cylinder on opposite sides thereof, so that they will constitute bearings for and support the so projecting portions of the bottom of the wrapper in the pocket of the cylinder which is opposite the top-tuckers. The said plates are represented as bolted to the hub E (see Figs. 2, and 4:) which is fast upon the stationary cylinder shaft E. The movement of the top-tucker slides in the ways f, is radial to the receiving-cylinder. This movement is imparted to them by their connection with the two arms P (see Figs. 3, 4:, 8 and 9) of a rock shaft P which extends all across the machine, and is supported in bearings in the side frames. This rock shaft P derives its motion from a cam P (see Fig. 24) on the cam shaft S, through a lever P which works loosely on a rock shaft Q (see Figs. 2, 3, 4; and 10) other purposes of which will be hereinafter described, the

a said lever Working on the rock shaft merely as a fulcrum and having at one end a roller 29 which works in a groove in the cam P" and having its other end connected by a rod P with an arm P ofthe rock shaft P The radial movement of the tuckers 19 thus given while the wrapper and the package are thus held in the wheel and the Wrapper is sup ported at the bottom on the plates W, tucks in the top of thewrapper at each side as shown at a and at the same time produces the side tucks a3, a While the foregoing operation is performed,the package is under or within. a stationary cylindrical curb W, of thin metal which surrounds the wheel for about three fourths of its circumference. This curb W is open at the sides in that part of it where the plates 19 operate.

The side tuckers are of two kinds of which, to distinguish them, I term one kind the F wing tuckers designated by the letter q, and 1 term the other kind slide tuckers, designated by the letter r, these terms wing and slide being selected because they express the character of the tuckers themselves. There are one of each kind on each side of the machine. The wing tuckers are for tucking or folding in the side tucks a and the slide tucke'rs for turning in theside tucks a. The relation of these tuckers to each other and their action on the wrapper are best illustrated in Fig. 2*, which represents one of each of said tuckers with the end of a package in the condition illustrated by Fig. 19. The said tuckers and their appurtenances, however,

are shown with more or less distinctness in Figs. 2, 4, 8 and 10.

I will first describe the wing tuckers g, which turn in the side tucks a to the position shown in Fig. 18. These tuckers have their inner faces which are presented toward the sides of the wheels and the ends of the package flat. They consist of thin plates of metal and are secured to what I call wings Q or they may be made of the same piece with the wings. These wings are fast to two small short rock shafts g, which are arranged on opposite sides ofthe machine in line with each other and parallel with the cylinder, in stationary journal boxes (1 (Figs. 2, 4, 8 and 10) which are fastened under the table I), the axial line of the centers of said shafts being a little behind the position of the top tuckers p, and the distance between the faces of the tuckers q is i such that they will allow room between them for the package, the top tucks a the top tuckers p, and the turned in side tucks of, room being required for the top tuckers 19 because the said wing tuckers q must operate before tucks necessarily carryin with them a portion of each bottom flap a. This portion of each bottom flap thus turnedin is folded by the finger (1*, which presses it downward and by the time the wing tucker has arrived at the position shown in Fig. 2*, in which it has carried the tuck a close to the turned-over flap if, the finger brings the turned in portion of the bottom flap down upon the central portion of the bottom flap which is supported by the sector plate TV; The lower edge of the tucker g forms the sharp crease a at the time the portion turned over from the diagonal line a is brought down by the finger 1*. The finger q*, does not, however, press down and flatten the edge of the fold at a. be done by means hereinafter described, after the completion of the formation of the bottom tuck a by the slide tuckern' has been effected. The turning of the rock shaft q to give the wing tuckers g the swinging motion by which they are caused to turn in the side tucks a and lie outside of the said tucks after having turned them in is produced by sliding rack bars which are best shown in Fig. 2, gearing with pinions (1 on the rock shafts q the said rack bars sliding in slanting fixed guides g secured under the table D, deriving their sliding motion from a cam Q (see Figs. 2 and 25) on the cam shaft S, the said cam acting through a rod Q, a rock shaft Q having arms Q, Q and rods q. The said rod Q is supported partly on a rocker Q, rocking on a fixed. pivot Q8, and partly in a guide Q secured to the framing, and is furnished with l a friction roller g" which works in the groove of the cam. The rock shaft Q is supported in fixed bearings in the side framing. One, Q of its arms is forked to receive a roller g on therod Q} and two other arms Q, are each connected by a rod q with one of the rack bars it The slide ers consist of straight fiat metal plates r of a width slightly less than the thickness of the package and for the purpose of giving them stability, they are attached to the slides 0" which work in slanting fixed guides 9' carried by brackets 1' secured to the framing of the machine. The ends of the said tuckers are rounded merely for the purpose of preventing them from catching in the paper. Their position (see Figs. 2 and 4c) is such that their movements That remains to back and. forth will be directly opposite and across the ends of the package which is in the pocket of the wheel in which the turning in of the top edge of the wrapper and the turning in of the tucks a by the tuckers p, and the. turning in of the side tucks m by the wing tuckers q have just been performed the tops being nearly even with the lines of the top and bottom of the package. On the backs of the tucke'rs rare downwardly projecting fingers 1", which resemble the fingers 1*, of the wing tuckers and the purpose of which is to assist the slide tuckers r to make a second diagonal fold at a in the bottom flap (1*, at the time that the said tuckers turn in the said tuck a The operation performed by'tli'e slide tuck ers r and fingers 'r*, is as fellows: The upward movement of each slide r, carries its respective tucker 1' far enough across its respective end of the package for it to carry in the tuck a and this tuck necessarily carries in with it a portion of the bottom fiap a*, which is thus bent diagonally on the line a and pressed down by the finger r until it is brought down close upon the portion of the bottom flap (1*, which rests upon the segment plate W. By the time the slide tucker has completed its movement, the finger brings the turned-over portion down upon the flat portion of the bottom fiap a and the lower edge of the slide tuckers has formed the sharp crease M. The finger r like that (1*, attached to the wing-tucker, leaves a portion of the bottom tuck turned in from the line a to be flattened down by devices which operate subsequently.

The movement of the slide-tuckers a" is effected by means of a cam R on the cam shaft S, acting through a lever R a rod R a rock shaft R, having arms R", R and rods 1, connecting the slides a" and the arms R, R with the rock-shaft R. The lever B turns loosely on the shaft Q which constitutes its fulcrum and one end carries afriction-roller 9*, which turns in the groove of the cam. The rockshaft R is journaled in fixed bearings in brackets R attached to the framing. It has two armsR', one for each slide and one B with which the rod R connects the lever B In Figs. 3 and 4, the arm R is represented as made in the same piece with one of the arms R. After the said tucks have been folded in and the portions of the flap have been turned in diagonally to form the bottom tuck 0. the receiving-wheel makes another movement which brings the pocket in which the preceding operations have been performed to the position in which the flattening of the folds of the bottom tuck on the lines a a is completed and the glue is applied to the trick. This last mentioned position in the example represented in which the wheel makes eight movements to complete a revolution, is directly to the right of the shaft E which presents the bottom of the package in a vertical position and presents the bottom fiapct of the wrapper in a vertical position against the lower part of the sector-shaped plates W. These parts of the sector-plates may be flattened to form better bearings for the pressing and gluing of the bottom tuck.

The devices which perform the flattening of the bottom flap and apply the glue thereto consist in what I call the pressing-dies T and the glue-dies U which are shown separately in detail in Figs. 29 and 30 and shown with more or less distinctness in some of the other figures as will be hereinafter pointed out. I term the die U the gluedie and the dieH hereinbefore described the paste-die because I propose generally to use paste with the die II for securing the edge a, that being sufficiently adhesive and I propose generally to use glue with the die U because a stronger adhesive material is required for securing the bottom flap. r

The glue-dies U of which there is one for each end of the package consist each of a plunger-like block the end of which as shown in Fig. 30 is of a triangular form corresponding with but not quite so large as the bottom flap a These dies are faced with india-rubher as shown at v. in Fig. 29. The pressing dies T as shown in Figs. 29 and 30'consist each of a box in which the said dies U work, the said box being provided with grooves t to form guides for fins 10*, on the dies. The exterior of the box corresponds with the dies and consequently with the bottom flap as shown in Fig. 20 and is of about the same size of the flap. Each block U is affixed to or formed integral with or as a projection on the face of a plate U the form of which is shown in Fig. 9 but better in Fig. 30. These plates are carried by two shafts U which are parallel with the planes of revolution of the receiving-wheel and capable both of an oscillating motion and a longitudinal movement in a fixed bearing 16 secured .to the machine framing, the oscillating movement being to carry the glue-dies to and fro between positions projecting doward from their shafts U in which they are opposite glue-feeders represented as consisting of rotary disks .5 (see Fig. 9) to a position projecting laterally from theirshaft shown in Figs. 9, 29 and 30 in which they are opposite the ends of the package in the pocket last mentioned. The longitudinal movements of the said shafts U are to press the glue-dies against the faces of the gluefeeding disks 8 to take the glue therefrom and to deposit the said glue on the sideflaps a a of the wrapper. The longitudinal movements therefore require to take place while the die-plates U are in each of the positions to which they are broughtby the oscillation of their rock-shafts. In their forward movements in the direction of the arrows shown on their shafts U in Fig. .29, the glue-dies are accompanied apart of the way by the pressing dies T which are each connected with its respective platesU by two short rods on bolts 25 provided with nuts on their ends and IIO
