Application filed August le, 1897.v

Brooklyn, county of Kings, and State 0f New York, have invented certain new and-usefull Improvemen ts Vin Wrapping-Machines, fully described and represented in the following specification and the accompanyingdrawings, forming a part of the same.

This invention relates tomachines of that class employed -inwrappingnewspapers and other publications orsimilar articles; i

In a machine constructed in accordance with the invention a succession of independent papers or other 'articles .to be wrapped are advanced and enveloped in wrappers Wound spirally abo'ut the papers as they are advanced, the wrappers preferably being aprplied in thefform of a continuous wrapper-, web, so as to form a continuous spirally wound wrapper-tube about the successive pa-` pers, which tube is afterward seve'red at or near the junction between successive papers and the wrapped papers delivered separately from `the machine.-

I "referably provide means whereby the papers as they are fed longitudinally forward I ,will be rotated, so that awrapper-'web, being guided tothe papers at an angle to the line in which .the papers are being advanced, will be drawn forward by the rotary and longitu-v dinal movements of-the'papers and wound es 1- plied by suitable .pasting devices to one edge spirally thereon,'the edges of successive layers or windings of wrapper overlapping and being secured together by a line of paste ap- .ofthe wrapper-web. I preferably employfeeding devices `engaging the outside of the papers or of the wrapper-tube inclosing the papers, and such exterior feeding devices are 'preferably mounted to rotate so as to form paper feeding and rotating devices. Any. 'suitable mechanism maybe employed for feeding the papers successively to the feed-` ing and rotating, devices but I preferably employ feeding `devices whereby the papers are advanced to the feeding and rotating de-- vices transversely vto the direction in which they are advanced by the feeding and rotating deyices, and I preferably provide arotary Serial No. 648,t' )89 y (No model.)

pocket in line with and rotating in time with the feeding and rotating devices, into which the papers are-fed and from which as they rotate therewith they are advanced .by suitable means -to the feeding and rotating devices.

The pocket is preferably open on one side to receive the lpapers as they are successively advanced transversely tothe axis of rotation ofthe pocket, Vas the papers may thus be fed .into the pocket withoutl its rotation being in#l terrupted for retyeiving them'. For advancing the papers from the pocketlpreferably provide a reciprocating rotary pusher engaging thel outer end ofthe paper and advancing the ,paper-'at the proper time from the poclget 1 thus. provide means whereby papers folded t0 theusuaLat form-may be successively fed to' the feeding devices of the wrapping mechanism proper at the desired intervals without the necessity of stpping'any part of lsaid.wrapping mechanism for thepurpose of receiving the papers.'

, ,Means are preferably provided for severing the continuous wrapper-tube inc'losing theA papers into paper lengths, so that the papers may be delivered'froi the machine. coinpletely wrapped and separated one from another.v Any suitable means may be provided for this purpose; but I preferto provide means forperforating the wrapper-Web before itis wound about the papers, and then to separate, by means of a pair of accelerated breaking-rolls, the wrapper-tube on these -lines of perforation's, the web'bein g perforated on the proper diagonal lines, so that'the linesof perforations in the wrappertube will be atright angles to the lengthf ofthe tube and at or near the junctions between 'successive papers.

cutting or otherwise` injuringthe papers is their mev sired. j In being wound spirally onto a at paper the wrapper-web will be takenup unevenly.

By. severing the wrapper-tube intopaper lengthsin this'mann'er all danger ofA "avoided and the papers may be Wrapped withv f ting ends as close together as de` I -thereforepreferably provide a tension and V take-`up device acting on the wrapper-web as it advances to the papers which will compensate for this uneven taking up of the wrapper# Treo `features of the invention, and such adescription will now be given in connection with the accompanying drawings, showing such a preferred construction embodying the invention, and the features forming the invention will then be specifically pointed out; in the` mechanism in-perspective.

claims.

In the drawings, Figure 1 is a plan view of the machine. Fig..2 is a longitudinal sectional view. Fig. 3 is4 a view taken on line 3' of Fig. 1 and showing the wrapper-feeding Fig. 4 is an ele- Fig. 5 is an end view of the wrapping mechanism from the left in Fig. 1. Fig. Gis a section on line 6 of Fig. 1.- Fig. 7 is a section on line 7 of Fig. 1. Fig. 8 isa sectionon line 8 of Fig. 1.' Figs., 9, 10, and 11 are diagrammatic sectional views showing the paper-receiving mechanism in dierent positions.

The various parts of the machine may be supported in any suitable manner, but arev shown as supported by standards A A A2 A3 A4. Extending longitudinally of the machine and journaled in the standards A A2 A5 A4 is a main driving-shaft B, having fast and loose pulleys C C', and from which the various moving parts of the machine are driven.

The papers having been fed successively to receiving mechanism hereinafter described are advanced to a pair of feeding-rolls aa', journaled in a rotary frame b, by which rolls they are advanced between guides 10, carried by the frame b, after leaving which they are enveloped by the Wrapper and then entered between feeding-rolls a a', journaled in a rotary frame b', by -which they are advanced through a guide 1-1 to a third pair of feedinglrolls o." ct", journaled in a rotary frame b". The guide 11 is carried by and rotates with the'framesb and b".

The rotary frames b b b are preferably of circular form and rotatably supported by circular guides or bearings 12, carried by -or form-ed by the upper part of the standards A2A3A4, and said circular frames are rotated from the driving-shaft B by gears 13, meshing with gears 14, .carried by said frames. Each pair of feeding-rolls a a and a a' and a" c. carry intermeshng gears 15 and are driven from a gear 16, journaled in the rotary frames and carrying a beveled gear 17, meshing with a beveled gear 18 on the shaft of one of the said rolls, the gear 16 meshing with a stationary gear or circular rack 19, carried by a-bracket 20, extending upward from the standards A2ASA4, as the case may be, so that as the rotary frames rotate about their centers the gears 16 will be caused, through their engagement with the racks 19, torotate about their centers, thus causing the feeding-rolls c an' a a, a to rotate. The circular racks bar'26.

19 are formed on the edges of rings which extend about and leave free the path of the paper. v

The papers are fed into the machine by feeding-tapes 23 and 24, which advance the papersv successively to a rotary pocket 25, formed, preferably, in sections carried by a The pocket, or each of the sections thereof when it is of the sectional form shown,

is open on one side and is formed, preferably,

with a wide side about equal in Width to the width of the papers to be wrapped, a closed side or bottom u, and a short side t, somewhat "less than hal-f the width of the side t, the :in-

side distance between the sides t and i; being about equal to the thickness of the papers to be wrapped. The bar`26 is supported at one end by the: rotary frame b, as shown in Fig. 2,'an`d at the other end bya rotary sleeve 30, as shown in Figs. 2 and 7, the sleeve 30 being journaled inthe standard A' and rotated in time with the frames b b' b from the shaft B by a gear 31, meshing with a' gear 32, c arried by the sleeve.

The operation of receiving a paper in the pocket 25 will be understood from Figs. 9, 10, and 11. Fig.v 9'shows the parts in position just as the paper has been fed to the pocket 25 by the tapes 23 and 24 against the long side ofthe pocket and beneath the short side and bottom of the pocket, which is uppermost. Then as the pocket continues to rotate in the direction of the arrow the paper is further fed, so as to enter its forward edge between the sides t and v of the pocketthis further feeding being accomplished by the tapes 23 and 24 as before until the rear end of the paper passesbeyond the roll 33aroun'd which the tapes 23 turn.

After the paperhas been advanced so that its rear end is no longer engaged by the tapes 23 it is further advanced into the pocket to bring its front edge against the side lor bottom u of thepocket by the feeding-tapes 24, which, as shown, are extended to rolls 34 on the otherside f the pocket, the tapes passing between the sections of the pocket. The

tapes 24 thus continue to bear on the paper tical position` shown in Fig. 11, thereby in- Suring the paper being properly' entered into the pocket. One or more circular guides 27 are preferably providedV to hold the papers in place in the pocket as the rotation of the pocket continues.-

After a paper has been entered into the pocket its rear end is engaged by a pusher 35, carried by a rod 36, mounted to rotate with, but free to reciprocate longitudinally in, the sleeve 30 and having its rear end mounted free to rotate`and reciprocate in the upper end of the standard A. The rod 36 is reciprocated by means of a rocking arm 37, hav- ICO IIO

inga p in entering betweenthe' flanges of a' spool 438 on the rod and having a'bowl 39V entering a cam-'groove in acam-cylinder 40, rotatably mountedv between the 'standards A and A and formed to'rock the arm 37 to ad Vance the pusher at the proper time to engage the paper after it has been fed into. the pocket and advance it longitudinally ,of the ,pocket to enter its front end between the feeding-rblls a, by whichit is then advanced, as before stated, .between the guides 10. The cam-cylinder 40 is driven bya' gear 41 on' the sleeve 30, which meshes with a gear 42 on the cam-cylinder. The feeding'of the papers into the pocket and the reciprocating of the pusher 35 are so timed that successive paperswill be fed to the feeding-rolls a and then advanced by the rolls a end to end and with their meet-v ing ends touching or with a desired spaeebe" tween them. i n Since thefeeding of a paper into the pocket 2 5 cannot be begun until the preceding. paper rear end entirely clear of the path of the pahas been advanced bythe rolls a to carry its pers as they are fed transversely into the pocket, and since a short interval of time must l rolls-a, so as to cause the front end of a paper as it is advanced by the pusher te catch up with the rear end of the preceding paper as desired.

After leaving the guides 10 the papers are associated with a wrapper-web, which inthe machine shown in the drawings is wound about the papers as a continuous or unbroken web to form a continuous wrappertubeabout the papers', being guided to the rotating and klongitudinally-advancing papers at anangle to the direction of movementof the papers by any suitable means, but preferably by feeding and pasting mechanism ,constructed substantially as follows: The wrapper-web y, coming from the web-roll, passes beneath guide-rolls 45 and 46, then vbaci; and upl be- -tween feeding-rolls 47 and 48, turning on the roll 48, and passing over a spring-tension device to be associated with the paper.- As the l web passes about the roll 4S itis engaged' by and receives a line of paste at one edge from a paste-roll 49, rotating in a fountain 50, the' roll 47 being cut away, as shown in Fig. 1,so as not to contact with the paper at the edge where the paste is applied. It will be noticed that 'tle paste is applied to that side and edge of the Wrapper which, when the wrapper is wound about the paper, forms the inner side gears 51 and are driven from a bevel-gear 52 on the driving-shaft B, which drives a bevelf gear 53, mounted free to' rotate on the 'shaft of the roll 48, said gear carrying also a smaller' gear 54, which, through an intermediate 55,

drives a large gear 56, fast on the shaft of the roll 47. This wrapper @feeding mechanism is arranged. so that the wrapper-web is advanced to the papers at van angle'as theyff' are'fed between thefeeding-rolls a and ,the feeding-rolls af, so that as the papers advance and rotate the wrapper' will be wound about 'the papers withits edges overlapping, vso as.

vto be secured bythe paste which hasbeen applied to the edge of the wrapper. Vpers as they are advanced by the rolls a and The ,ipa-

into Vthe guide 11 will thus bein'closed in a.

continupus spirally-wound wrapper forming .a continuous wrapper-tube inclosing thesuccessive papers.

= It will be seen that the papers may be advanced for wrapping with the ends-of successive papers separated a sh'ort distance, so that when the wrapper-tubek is severed, into paper lengths each paper will be inclosed in a'wrapperrtube projectingbeyond the ends` of the paper to protect thepaper, or the papers may be advanced for wrapping with the ends of successive papers meeting orsubstantially so,so' that whenthe wrapper-tube is severed. into paper lengths each paper will be inclosed in a wrapper of substantially the length of the paper. l

' For the purpose 'of peiforatingthe wrapperweb for severing the wrapper-tube into paper lengths the roll 47 is provided'with a diagonal perforating-strip 57 ,whereby as the web passes between the rolls-47 and 4S and at each rotation of the roll 47 it will receive a line of per- IOO forations diagonal to the lengthof the web and at right angles to the direction'ofmovement ofthe papers,as shown in Fig. 1. The roll47 is of 'such diameter', according t'o the size of the papers to be wrapped, that for each rotation of the roll a length of the wrapper'rweb will be advanced sufficient to form a length of the wrappentube equal to the length of a paper,-

or'a little more if it be desired to deliver the papers with wrappers proj ectingbeyond'their ends. The feeding-rolls o." are driv'enat -a ,slightly greater speed than the rolls a and the rolls a', so that 'when the papers inclosed in the continuous but perforated wrappertube enterbetweenthe rolls a" after passing through the guide-tube 11 the wrappertube will beseparated on the perforated lines and the papers delivered from therolls-a. each with its portion ofthe wrapper-tube separatedv from that of the next succeeding paper. ,One

of the rolls a." is preferably spring-pressed,

as shown, soas to insure. the wrapper and inclosed papers being tightly gripped for breaking the wrapper-tube. By thus perfo` rating the wrapper-web before igiswound j .Y about the papers and then'- breekjng the' wrapper-tube on such perforated lines the Wrapper-tube is severed into paper lengths without danger of injuring the papers however closetogether they are.

The wrapper-web, as it is wound onto papers folded in the usual manner for wrapping,

will, on account of the flat form of the papers,

be taken up unevenl-y, and as the wrapperweb is advanced from the feeding-rolls 47 and 4.8 at a uniform rate Iprovide between said feeding-rolls andthe pointwhere the wrapper is associated withV the papers a spring-tension,

and take-up device, preferably a tension-roll 60, which 'is shown as carried by a forked arm 6l, extending from a pivot-shaft 62, and

under light tension by the coil-spring 63 to4 for wrapping newspapers and other publications, ye't it is to be understood that it is not to be limited to such use, but that wrapping-machines embodying the invention or` features thereof as claimed may be employed for wrapping other articles for which they may 'be found suitable, the term paper beingused in the .claims to include all such articles.
