THEODORE G. McGIRR, OF NEW YORK, N. Y., ASSIGNOR TO ACME WRAPPING MACHINE COMPANY, OF NEW YOBK, N. Y., A CORPORATION OF NEW YORK.

WRAPPING AND LABELING MACH INE.

Specification of Letters Patent.

Patented Feb. 22, 1910.

To all whom 'it may concern:

Be it known that I, THEODORE G. McGmR, a citizen of the United States, residing at New York, in the county of New York, State of New York, have invented a new and useful Wrapping and Labeling Machine, of which the following is a specification.

This invention relates to machines for wrapping and labeling articles.

One object of my invention is to simplify the construction and operation of wrapping and labeling machines, to increase the output, and to deliver the wrapped articles in a stacked form for convenience of removal and packing.

Another object is to deliver, one by one, printed labels from a stack of such labels in such position that the'same will be folded about the articles to be wrapped.

Another object is to apply gum or other adhesive to the label or outside wrapper and to fasten the same about an inner wrapper of the package in such wise as to ,causcfhe same to retain its folded or wrapped shape or form.

Another object is to make the folding mechanism readily accessible in case of accident, or derangement for any cause, to any of its parts; other objects will hereinafter appear.

My invention consists of features of construction arrangements and combinations of devices hereinafter described and more particularly pointed out in the appended claims.

My invention is embodied in the machine illustrated in the accompanying drawings, forming part of this specification, in which:

Figure 1, is a front elevation, with parts broken away and removed in order to show the parts behind and to get the whole upon the sheet of drawing; Fig. 2, is a plan view; Fig. 3, is a plan view of the machine below the plane AA of Fig. 1; Fig. 4, is a side elevation from the top 1n Fig. 2, of the label feeding mechanism; Fig. 5, is a vertical central sectional View of the same; Fig. 6, is a detached view, partly in section, of the stacker device; Fig. 7, is a sectional view of the driving mechanism for the label feed; Fig. 8, is a detail view of the knife operating mechanism; Fig. 9, is a view from underneath of the top folding mechanism; Fig. 10, shows at the right a front View of half the folding mechanism and at the left a side elevation of the same; Fig. 11, is a detail view of a tucker-device; Fig. 12, is a sectional view ofthe pusher and bridge-piece; Fig. 13, is a plan view of the same; Fig. 14, is a perspective View showing-the package, the wrapper and the label at the beginning of the folding operation; Fig. 15, shows the same in'perspective after the sides and ends have been folded in as the plunger moves the parts downward; Fig. 16, shows the same in perspectii e at a further stage of the downward motion; Fig. 17, shows the same in perspective at the completion of the downward m'otion; Fig. 18, shows the said parts in perspective as they appear at the completion of the first stage of themotion of the horizontal tucker or plunger; Fig. 19, shows the same'in perspective at the completion of the folding in of the forward ends of the wrapper during the horizontal motion of the package; Fig. 20, shows the same in pers ective at the completion of the foldin own of one side of the'wrapper and labe and Fig. 21, shows the completely wrapped article.

The reference, 2, marks fixed vertical sides of the machine; these sides are united by tie rods, 3, and platforms or tables, 4, 5, hereinafter referred to. The articles to be wrapped are placed in the Vertical guideway, 6, which has an open side, as shown in Fig. 2, to facilitate the insertion of the articles. This guideway, 6, rises from the table, 4, and is cut away on.its two sides to permit the pusher a to push the lower-most article therefrom and under the plunger I). The pusher or plunger 0 moves to and fro in the fixed guides a attached-to the table, 4, by screws or otherwise, and is provided with an underneath extension or lug a" which passes through a slot in the said table, 4; to this underneath lug or extension (1" is pivoted at, a, a link, a, whose other end is 'pivotally connected with the lever, a. The lever, a is pivoted at, a, to a collar, afixed upon a tie rod, 3, and said lever, (1- is provided at, a", with a stud and roller which engages with the groove of a drum cam,.a which is fast upon the driving shaft D upon the machine. The cam, a is shaped, proportioned and timed to move the pusher a as hereinafter described.

Thepaper, or foil, or both, from which the wrappers are formed, is fed from rolls arm or lever,

by the mechanism shown, claimed in a companion application for Letters Patent filed Feb. 2, 1909, Serial No. 475,689; the rolls are not shown herein, but certain of the feed rolls are indicated at, q, with their gears, 7, 8, and ratchet, 9.

The wrappers are severed from the web or webs by the oscillatory lmife, 10, which is pivoted at, 11, to the fixed frame-work of the machine and is provided with an arm, 12, and-a stud and roller, 13, for engagement with the grooved cam, 14, mounted on the fixed shaft of the roller, q, and driven by sprocket chain, 15. The knife, 10, coacts with the fixed edge or blade, 16,to sever the'wrappers from the web or webs (see Fig. 8). The wrappers so severed from the webs are immediately underneath the head I) of the vertically moving plunger above the mouth 0 of the first fold-ing mechanism. The head 6 is carried by the rod 1) which is guided in a vertical direction by the guides, N, which are attached to the frame work of the machine. The rod 1) is connected by a, pin and stud, b with a slotted arm or lever, b, integral with or attached to a sleeve, b, which is journaled upon atie rod, 3, of the machine, the tie rod in this instance having collars attached thereto between which the said sleeve works. The said sleeve, b", is provided with an arm, I), to which the upper end of a pit-man, b, is attached. Preferably, the pitman, 6 is adjustable as to length. The lower end of said pitma'n is pivotally connected with an 12 which is fulcrumed at, I)", on a tie rod, 3, inthe base of the machine, said pivot, 6 working between collars attached to the said tie rod by set screws or otherwise. The lever, I)", has a stud and roller, b, thereon which co-acts with a cam groove in the disk, I), whereby the said lever, b, is moved up and down in order to rock the lever, b, and move the rod up and down to operate the plunger 1).

In order to carry the labels across the mouth 0 aforesaid, the slide or pusher a has attached thereto, or is formed w1th, a bridgepiece, a", over which the label-feeding devices hereinafter described feed the label while the said bridge-piece, a, covers the said opening, and which bridge-piece is withdrawn from underneath the label on the return of the plunger a to the right in Fig. 2, whereby the label is left underneath the wrapper or wrappers cut oif by the knife,

10, and on which cut-oflI' wrapper or wrappers the lunger a has just. deposited one of the articles to be wrapped. The relative position of the label, 1, wra per w and article p at this time is indicate in Fig. 14. As

the plunger 1) moves downward, it comes in contact with the article p and pushes it and its wrapper and label down through the said mouths and the long sides of the Wrapper described and As the plunger w and the label are folded against the edge of the article p, as indicated in Fig. 15, by the sides of the said mouth a; after which the end w of the wrapper is folded in as indicated in Fig. 15, by the upper tuckers 0, shown more clearly in Fig. 10, thus producing the box-like structure shown in 'Fig. 15. 1) moves the article further downward, the triangular corners -w are folded in from the position thereof shownin- Fig. 15, to the position thereof shown in Fig. 16, by the scrolls, c and thereafter during the further downward movement of the plunger, the corners, w of the wrapper are folded in from the position thereof shown in Fig. 16, to the position thereof shown in Fig. 17, by the scrolls 0 After passing through the scrolls, c 0 the plunger b deposits the article, wrapped as shown in Fig. 17, on the table, 5, where the article is held stationary by means of the spring, 0", which passes through the opening, '0 in one of the side uprights, c. For convenience of access to the guideway formed by the walls, 0, two or more of the scrolls, c 0 are hinged at, 0, so that the same may be swung back to permit of access, to the guideway formed by the said walls, a, of the said scrolls. A keeper, 0 is hinged to one of the scrolls at, 0, and engages by a slot with'a pin, 0 on the other scroll to lock the said scrolls 1n their closed or working positions, and frees them so they may beopened when it is lifted or turned upon its pivot to a sufficient extent to disengage it from the pin, 0

The partially wrapped article is next moved horizontally toward the stacker by devices now tobe. described. The table, 5, is slotted at, 17 to form a guideway for the horizontally acting pusher d which has an arm'extending down through the slot aforesaid, to which arm is pivotally connected at cl a link, d whose other end is pivotally connected at, (1 with a lever, (1*, which is journaled upon a tie rod, 3, of the machine and is operated by a cam, (1 on the shaft D aforesaid. The cam, (Z operates the leverby means of a forked rod, d, which straddles shaft D and carries a roller which co-acts with the cam, d; the rod, (Z is pivotally connected with lever d.

The pusher d is formed to guide the tucker, d, which slides upon the pusher d and is held forward in the position thereon indicated in Fig. 11, by means of a spring,

which surrounds a rod, d", extending from the pusher d and provided with an adjustable abutment, (1 for said spring, the said spring abutting against the finger, (l. The finger, d, is provided with lugs or pins, (1", which abut against the fixed part of the machine, as the standards or guides, 0, aforesaid, to arrest the said finger after the said finger has folded in the rear ends w,

eaaeoa w from the positions thereof shown in Fig. 17, to the positions thereof shownin Fig. 18, but the pusher d continues to advance and pushes the article onward into the channel 6 and under the vertical blades or tuekers, ee between which tuckers and the side walls of the channel the vertical or upstanding ends, Z, of the label and upstanding edges or sides, 11: of the wrapper or wrappers pass while the said tuckers 6, 6 fold in the leading ends, 10 from the positions thereof shown in Fig. 18,to the positions thereof shown in Fig. 19'. Each successive partially wrapped article moved forward by the pusher (Z advances the partly wrapped article ahead of it along the said guideway or channel e and under the tuckers, a, 6 and the sequence of the operations in such forward motion of the articles is as follows: After the forward ends are laid down scroll, e lays the label and thereof shown thereof shown down the narrower side of wrapper from the position in Fig. 19, to the position in Fig. 20, after which the scroll, e lays down the wider side of the label and the wrapper from the position thereof shown in Fig. to the position thereof shown in Fig. 21, and the said article then passes under the fiat side, 6 of the scroll, 6*, and into the stacker. During the progress of the. partly wrapped article through the guideway e, gum or other suitable adhesive is applied to that part of the label which projects abovethe wrappers as shown in Figs. 15 to 20, and appliances for gunnning the label will now be described:

Any suitable adhesive is placed in the receptacle or fountain g, which is attached to or is carried from the table, 5, by means of a bracketg' or otherwise. Above the fountain g is a rotatory shaft, 9 having fixed thereon a gear, 9 which meshes with the gear, f, on the fixed frame-work of the machine. The gear, 9 is driven, in the instance shown, from the shaft D by a sprocket gearing, 9 Partly inside the fountain g is a disk, which is fast upon' the shaft, g aforesaid, and scrapers, 9 are attached to the fountain at that side thereof where the said disk, g, rises out of the mass of adhesive, the function of the said scrapers being to prevent the disk from carrying around with it more than a thin film of the said adhesive substance. Outside the fountain, the said shaft, 9 has fixed thereto a beveled gear, 9 which meshes with a similar gear, 9, journaled on the bracket, g Immediately above the beveled gear, g, is a disk, g", which is attached to said gear and the periphery of which disk rubs or bears lightly against the face of the disk, 9, afoiesaid to take adhesive therefrom. The disk, g, transfers the adhesive to a second disk, g, also. journaled in the bracket, 9

as indicated in Fig. 19, the

The disks, g and 9 are geared together by spur gears, 9

The afore said long upstanding side of the label, 1, bears against the periphery of the disk, 5 as the articles pass. along the passageway e aforesaid and takes adhesive from said disk, and when the said long side of the label is laid down upon the article as indicated in Fig. 21, the label is .gummed to itself to form an external wrapper which holds down the wrapper w aforesaid. It is noted that by having the disk, 9, run at a rate of speed different from that of the disk, (Z where the two touch each other, and by having the disk, g also run at arate of speed different from that. of disk, g the transfer of gum from one to another disk is facilitated, as there ensues a wiping action of one disk on the other.

The wrapped articles deliyeredsfroin the passageway e are delivered one by one at intervals to a stacking apparatus now to be described. Attached to. an extensionof the table, 5, is a vertical guideway f of an inside length horizontally, slightly greater thanthe length of the Wra ped article and of a width horizontally sufllcient to allow the .articles to move upwardly therein without undue friction. The said guide or stack f-is provided with a passageway through its ase for a reciprocatory carrier or stackerlever f of the stacker. This lever f is pivoted at, P, between -lugs,] on a ram, f, and a spring, 1'', is provided between the end, f, of thecarrier, .f, and they-rain for accelerating thedownward motion of the .le-

ver after the goods have been deposited within the stacking chute". or-fstack f. A pawl or dog, is-pivoted to the ram at, f and is drawn toward the pivot, F, by .a

spring, f and is adapted to hook over a pin or stud, f, on theside of the arm, f, to hold the lever If up when delivering goods to the staking chute. The carrier f is held up in position to receive the wrapped 'article in the depression, f, thereof, the ends of the said article eXtendin laterally beyond the carrier at each sice thereof, and above the shelves, f", near the bottom of the stack Beyond the depression, f, the carrier is provided with a table, and below the end of the table, f, is a cam, f attached thereto, the said cam being adapted for co-action with the fixed stud or roller, f, on the frameortable, 5. The ram, f", is moved to and fro by means of the bell lever, f which'is fulcruined at, f", and engages by the slot and pin, f, with said rain.

The other end of the said lever, f is i otally connected at, f, with a link, 7,

which is pivotally. connected at, f, with the pusher (Z aforesaid, the arrangement being such that as the said pusher (Z makes its return or-deadstroke the ram is advanced to carry the wrappedarticle under the stack The front wall of the stack f'is curved outwardly at, f, for the purpose of guiding the articles into the stack with greater certainty.

The operation of the stacker is asz follows: The stacker-lever f, in the position thereof shown in Fig. 6, is suppesedto be moving to the left and to have a wrapped article in the recess, f, thereof, and as the ram, f is advanced from the position thereof shown in Fi 3, to. the right the carrier f carries t e wrapped article in the said recess, P above the shelves, f", aforesaid; before the ram completes its forward or workin stroke, however, the pawl, f strikes a xed corner, f, on the machine and is disengaged from the pin, f aforesaid, whereupon the spring, f, raises the end, f, and depresses the end or table, f, more than enou h to disengage the wrapped package from t e recess. or depression, f, thereby depositin the'said package on the said shelves, f Tt should be remarked that if there are any packages in the stack f,

such packages are lifted and held above the top, or at east flush with the top of the wrapped package in the depression, f, as the said ram advances, whence it results that the wrapped packages are laced in the stack from underneath. Ont e return stroke of. the ram and very near the end thereof, the cam, f, strikes the stud or roller, f and the stacker lever is raised to the position thereof shown in Fig. 6, and

the pawl, f engages with the pin, f, to re tain the stacker lever in the position shown in Fig. 6. The articles are fed from the channel e out over the stacker lever f andunder the rolls, f, as .the ram is onits return or dead stroke, and are received by the flat surface, f of said lever f. The articles are prevented from moving with the lever f at such times, however, by the fixed sto f. The rollers, f, are journaled on stu s on a lever, f, fulcrumed at, f, and having a weight, f adjustable therealong. The articles drop into the recess, f, one for each stroke of the ram as" the lever, f reaches the end of its return or dead stroke. Y

The devices shown for feeding the labels, one by one, underneaththe plunger head 2) will now be described, reference being had more particularly to Figs. 2, a, 5 and 7. The labels with their printed faces down are placed in the ,guideway formed by the fingers h h and rest upon the belts, 12, of rubber or other suitable material; the belts, 72. run upon the pulleys, h", h*- .The pulleys, h, are fast upon a shaft, 75', which is journaled in the side frames, h, and-forms the driving member of the combination. The said shaft, It has fast thereon a ratchet wheel, h, and the said shaft, h, alongside the ratchet wheel, it", carries a gear wheel, h which is loose thereon. The gear, h

eaae cc carries a spring-pawl, it, pivoted thereon, which is ada ted to engage with the wheel, h, aforesai The tail of this pawl extendsbeyond the periphery of the gear, h

' and is adapted to co-act with a cam, h, so

as to be disengaged, while in contact with said cam, from the said wheel, h, whence it results that the continuous motion of the gear, hf, gives only an intermittent motion to the pulleys, if, and the parts ,operated'thereby. The gear, h, is rigidly connected with a sprocket wheel, k, which is free to turn on the shaft, h". The sprocket, h, is driven by a chain, b and sprocket, h, from a shaft connected by beveled-gears, h with the shaft 1) aforesaid. Above and co-acting with the belts, W, are stationary rolls, h and between *the pulleys, h aforesaid are disks or rollers, h. The disks, h, project beyond the belts, k and co-act with friction disks, h 5, whose peripheries are covered with soft rubber or other suitable friction material to feed the label forward and down between the rollers, h, h", a guide, it, bein employed to guide the forward end of t e label down between the rollers, h, h, and to direct the saidhibel along the table, 4,. and under the feed rolls, It. The rollers, h", are fast upon a shaft, h, which is driven from the car, h by a train of gears, 11. The sha t, h, forms the axis of motion of the lever, h", at the free end ofwhich lever is a rotary shaft, h, on which is fast a roller, h. The shaft, 71, is driven'from the shaft, 20, by the train of gears, Jr. roller, h, is placed a roller, h, inthe slot or opening in the table, 4. The lever, 'h, is normally drawn downward by the spring, h"; Near its end, the lever, It, is provided with a pin, it, which 'coacts with the cam, a, on an arm all extending from the pusher a aforesaid For the purpose of agitating the wrappers in the guide, h, an agitator, it, is journaled upon the axis of Directly under the drop the roller "h aforesaid and is provided -turned to normal position by gravity or by a spring, h. The cam, It, may be adjustable as to position-and length.

The operationof the label-feeding devices is as follows Art the periodic operation of the pawl and ratchet mechanism connecting the shaft, h, with the gear, It", the bottom label of the stack is carried by the pulleys and belts. under the rollers, h, and between the feed rolls, h, h, and thence downward between the feed rolls, h, it, along the guides, k and under the feed rolls, h the printed face of'the label being downward. When the pusher a is at the end of its return, the cam, a, co-acting with the pin, h has raised the roller, k ,..oa't of means contact. with the roller, h, and the label fed forward by the roller, k rests. upon the roller, h. As the pusher a begins to move forward on its operative stroke, and as soon as the cam, a t, releases the roller, h, and allows it to drop, the continuously rotating roller, h, coacting with roller, k feeds the label forward over the bridge piece, a, aforesaid and against a fixed por tion of the machine so that, on the return stroke of the pusher a and the bridge-piece, a, the label is retained in position underneath the wrapper w and the article 7) as shown in Fig. 14;. v
