Application led March 5, 1914. Serial No. 822,639.

To-aZZ whom it may concern Be it known that FELIPE Gmooo, late e. citizen of the island of Cuba, and a residantof the city of New York, in the county of New A ork' and State of New York, decom. did invent a. certain new and useful mproveinent in Wrapping-Machines, of which the following is a. specification.

' This invention relates to improvements on machines in which an article and a wra. per are successively assed through fol 'ng devices, whereby t e Wrapper is folded upon the article.

The object of the invention is to provide means whereby e Wrapper can be folded around en article in such o. manner that all 'if the folds are so placed that a. second Wrapper in the form of a. single'bend folded around the Wrapped article Will cover all of the folds of the rst Wrapper.

The invention consistst of two Wrapper folding channels in alinement, each channel having stationary folders, the folders of one channel being in alinement with e folder of the other channel. A wrapper feeding mechanism is provided which is adapted to move a Wrapper to rest between seid Wrapper folding channels, and into range with o; paste applying device. A reciprocating plunger is arranged to move a partially Wrapped article through one of seid Wrapper folding channels, whereby the Wrapper is folded upon the article, and es the plunger continues its forward movement, the Wrappsd article forces the second Wrapper f through the second Wrapper folding channel, whereby the second Wrapper is Wrapper. Two swinging folders complete the folding of the second wrapper upon the folds of the rst Wrapper.

ln the accompanying drawings: 1iiigure l is a sectional plan View of part of a machine embodying the invention. Fig. 2 is a: sectional elevation of the line ll-l of Fig. 1. F ig. 3 is s View similar to Fig. 1, showing certain parts in a dierent position. Figs. d to 10 inclusive represent the dierent stages which a Wrap-per passes through in being folded upon-v sn. article, during partiel travel of said article and wrapper through the maehine. Figs. l1,

lim"- tinlly folded upon the folds of the/ list 12 and 13 represent the different which a second wrapper posses through in being folded upon the wrapped articles, end second wrapper through port of the inschine. Fig. 14 is sectional elevation on the line XIV-XIV of Fig. 3. Fi 15 is e transverse section on the line of Fig. 3. Fig. 16 is e section on the line XVI- XVI of Fig. 3, showing means for applying paste to the second Wrapper.

A power driven shaft 1 is jodrneled et 2 in the main frame 3. A. lever is pivoted at 5 and provided with e roller (i Willich engages a cani Z secured to shaft l. lle-ver l is connected buv o link 8 to e slide 9 Whieh rides in guides 10. Forming psrt of slide 9 is s plunger 11. Lever il is also connected by e link 12 to e. lever 13 which is pivoted at 14 to the main freine. The lever 13 is connected by e link 15 to e slide i6 which rides in guides 17. Forming port of slide 16 is s plunger 1S which moves trenswerse"yv to the line of travel of plunger 1l. Corn 7 causes back and forth movements of erin l. which movements ere transmitted to erin i3 by ineens of link 12.

By reference to Figs. l, is and it Will be seen that the plungers which ore connected to the srnis d and 13 here such relation to each other the?. when one plunger reaches the end of e' forward moveinen the other plunger Will here resched th versa. A bevel gear Wheel l@ secured to shaft 1 is in mesh with e, bevel gear Wheel 20 which is secured to s vertie-l shaft 21. Vertical shaft 21 rotates in :i besring 22 and extends upward for the purpose of ectuating a paper feed mechanism. The peper feed mechanism is omitted es it forms no g port of the present invention. il. Wrapper 28 is fed by said paper feed meclisnisrn to a guide 24 which hss supports 2.5 which the Wrapper rests. To the guide 24 is a support 26 upon which en article 27 is placed after the plunger ll. has reached the end of its .oecli'werd more ment. Then as plunger ll more forserd it will force the article f2? egainst the per 2e, thereby forcing the wrapper tween en upper plete 28 and s lower 29, and between central side Selden;

'a dhannel 31, Ycausing the wrapper to be folded upon the article in the manner shown in Fig. 4. Continued forward movement of .plunger 11 causes upper side aps a' of the tion shown in Fig. 6. At the end of forward movement of plunger 11, said article and wrapper will be moved into range with the plunger 18 which is then at theend of its backward movement. A side end flap c will thenv be in range with slide 34 which has movement on guide 35 placed transversely to the line of plunger 11. Pivoted at 36 to the slide 34 isa' pawl 37 which extends into range with a projection 38 on plunger 18.

By means of a spring 39, an inclined face- 40 of the pawl 37 is held against a pin 41. During backward movement of plunger 18, pawl 37 is moved aside by projection 3.8, said pin/41 permitting the pawl to be moved into range with said projection 38, at the end of thebackward movement of said pluner. g The mechanism so far described is shown and described in an application for patent filed b Felipe Giroud, July 14, 1911, Serial ho. 638,484, for an improvement in wrapping machines, and is inserted in this application in order that coperation therewith of other mechanism, hereinafter described, can be understood.

" Secured to vertical shaft 21 is a chain wheel 42, over which rides an endless chain 43. The chain 43 traveling in the direction indicated by the arrow in Fig. 3, passes over anidle chain wheel 44, and over a chain wheel 45, thereby causing rotation of chain wheel 45l in the direction indicated by an arrow. Fromchain wheel 45 the chain 43 passes over and causes revolution of a chain wheel 46 in a direction opposite to that of chain wheel 45. From chain wheel 46 the chain 43 passes over and causes revolution of a chain wheel 47 in the direction indicated by an arrow. From chain whccl 47 the chain 43 passes over an idle chain wheel 48, and in returning to chain wheel 42, passes over an idle chain wheel 49. The chain wheel 47 is secured to a vertical shaft 50 which rotates in a bearing 51. To the upper end of shaft 50 is secured a rubber finger "52, which during rotation of said shaft takes against and causes one of a series of wrappers to be moved into engagement between feed rollers 54 and 55. nAlso resulting in reciprocating movements of the slide. Said reciprocat|ng movements of the slide cause rotation of a knife 60, which knife serves the purpose' of preventing movement of more than one of the wrappers 53 by means of the rubber finger 52 on vertical shaft 50. y

The means whereby movement of slide 58 causes revolution of knife 60 is not described, as it forms no part of the present invention.

The feed roller 54 is secured to a vertical shaft 61 to which the chain wheel 4G is also secured. Secured to vertical shaft 61, is a gear wheel 62 which is in mesh with a gear wheel 63 secured to a shaft 64, having the feed roller secured thereto. It will be readily seen that rotation of chain wheel 46 by means of "chain 43 causes rotation of the feed rollers 54 and55.

Rotation of the feed: rollers causes the wrapper fed between them to be moved forward to rest across the line of travel of the plungers 18, a portion of said wrapper being in range with the folders of one channel which are in alinement with a folder of the The chain wheel 45 is secured to a ver-` tical shaft 65 which rotates in a bearing 66. To the upper end of shaftY is secured a roller 67 which rotates in a receptacle 68 in which paste 69 is placed, the receptacle having an opening 70 through which the roller carries paste to the exterior of the receptacle. Also secured to vertical shaft 65- is a gear wheel 71 which is in mesh with a gear wheel 72 secured to a` vertical shaft 73, having a linger 74 secured thereto. Rotation of vertical shaft 65 causes rotation of' the shaft 73 carrying the finger 74, and the finger is adapted, during said rotation, to take paste from the roller 67 and to deposit said paste upon a portion of the wrapper 'i ions'hown in Fig.` (i to the with projection 38; and the pawl and slide p will then be returned to their yoriginal position by means of the'spring 39.

As plunger 18 continues its forward movement, it will takev against andv accordingly dvi. E3@

force the article and wrapper forward along a channel 75 causing the side end i'iap d to take against a central end folder 75, which will cause said side endiap to be folded from the position shown in Fig. 7 to the position shown in Fig. 8. Continued foru ward Increment of plunger 18 and conse- Y quent forward movement of the article and Wrapper along channel 75 causes upper end flap e to take against an upper folder 77, which will cause said upper end flap to be folded from the position shown in Fig. 8 to theI osition shown in Fig. 9. Further for- War 'movement of the article and wrapper by means of plunger 18 causes the lon er end flap f to take againsta lower' folder 78,

l which folds said lower end flap from the po of forward movement of plunger 18, the

and the second wrapper' foldedvas in Fig. 11, will be moved into a' wrapped article,

receiving channel 80. An end liep it of the second wrapper will then be in range with a swinging folder 81, and an end flap c' will be in range with a swinging folder 82. The folderll is pivoted at 83 and is provided with a downward extension `84, having a roller 85 at its lower end adapted for enagement with a cam "86 secured to the driving shaft 1. The roller Szjsheld in engagement with cam S6 by means of a spring 87. The folder 82 is pivotedv at 88 and is provided with a downward extension 89, having a roller 90 at its lower end, held in en gagement with aA cam 91, on the driving shaft, by means of a, spring 92. p The cams 86, and 91 have such relation to each other and to the mechanism actuating plungers 11 and 18, that after said mechanism causes return movement of plunger l18, cam S6 will cause folder 8l to turn the flap It from the position shown in Fig. l1 to the .position shown in Fig. 19.. and after return movement of folder 81, cani will cause folder S2 to turn flap from f the position shown in Fig. 12 to the position 'shown in Fig. 13. The

p Le g on flap z' will cau'sesaid flap to adhere to ilap 7i, thereby holding the second wrapper folded. in the manner shown.

By reference to the Figs. 4 to 13 inclusive, it "will be seen that all folds of the first wrapperire covered by the second wrapper when folded as'shown in Fig. 13.
