MEAD, AND' CHARLES YV. CARPENTER, OF NEW WRAPPING-MAOHINE.

SPECIFICATXON forming part of Letters Patent No. 603,585, dated May 3, 1898.

Application filed August 4, 1897. Serial No. 647,040. (No model.)

To all whom, t may concern.-

Be it known that I, LUTHER C. CROWELL, a citizen of the United States, residing at Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Wrapping-Machines, fully described and represented in the following speciiioationand the accompanyingdrawings,form ing a part of the same.

This invention relates to machines of that class employed in Wrapping newspapers and other publications or similar articles, and more particularly to such machines whereby a succession of independent papers or other articles to be wrapped are advanced and enveloped in wrappers wound spirally about the papers as they are longitudinally advanced, the edges of successive layers or windings of Wrapper overlapping and being secured together by a line of paste applied by suitable pasting devices to one edge of the Wrapper. A continuous Wrapper-web is preferably employed to form a continuous spirally-wound wrapper-tube about the papers, which is afterward severed at or near the junction between the successive papers and the wrapped papers delivered separately from the machine.

According to the present invention the papers are advanced by in terior feeding devices, and in the preferred construction embodying the invention the successive papers are bent about a core and advanced longitudinally on the core by belts forming a portion of the surface of the core, a continuous wrapper-web being wound spirally about the core and the papers thereon to form a continuous spirallywound wrapper-tube inclosing the papers and the core. The core is preferably arranged to rotate, so that the wrapper-web, being guided to the core at an angle, will be drawn forward by the rotary and longitudinal movements of the papers on the core and Wound spirally about the papers and the core. The papers are preferably fed to the core by mechanism advancing them successively in a direction transverse to the axis of the core.

The core is preferably of such a size that its circumference is about equal to twice the width of the papers to be Wrapped, so that the papers will extend about half-way around the core. The wrapper-tube formed about the paper and the core will thus be of a size that will permit the papers being flattened out after leaving the core and to iit snugly about the papers when they are so flattened out. By the width of the papers is meant the dimension of the papers measured circumferentially of the core.

For severing the wrapper-tube at or near the junction between the successive papers, so that the papers may be delivered from the machine completely wrapped and separated one from another, I preferably employ one or more-depending upon the ti ming of the parts of the machine, but preferablya plurality of continuously rotating segmental severingblades, arranged to move longitudinally of and at the same speed with the wrapper-tube during the time that they7 are rotating in cutting position, and saidv blades being returned to their original or normal position during that portion of their rotation in which they are not in position for engaging the wrappertu'be. The rotation of the segmental severing blades being properly timed and the blades extending through the proper portion of a circle, according to the rate of rotation of the core and the number of said segmental severing-blades employed, the rotatingwrapper-tube will be completely severed at the desired points between the papers.

n The invention includes also, broadly, a wrapping-machine having a core, preferably a rotating core, upon and longitudinally of which the papers to be wrapped are advanced and simultaneously enveloped in wrappers applied about the papers and core in any suitable manner, although the method of spiral .winding is preferably employed.

A full understanding of the invention can best be given by a detailed description of a preferred construction embodying all the features of the invention, and such a description will now be given in connection with the accompanying drawings, showing such a construction, and the features forming the invention will then be specifically pointed out in the claims.

In said drawings, Figure l is a plan View of such a machine, partly in section. Fig. 2 is a front elevation, partly in section, on line 2 of Fig. 1.

severing mechanism in elevation.

Referring to the drawings, the rotating core 100, about which the papers are bent While being inclosed in the spirally-wound wrappertube, is carried by a rotary frame 101, mounted to rotate in bearings in standards E E and rotated from the main driving-shaft B'by means of a gear 102 on said shaft, meshing with a gear 103, carried by the frame. The core is inclosed in a cylindrical casing 104, :supported by the standard E and by standards E2 and E3, in the space between which 'casing and the core the papers are advanced spirally and inclosed within the wrapper, asy

hereinafter described.

The core is Vformed with a portion of its surface arranged to move longitudinally from A, the yframe 101 for the purpose of 'advancingj the papers longitudinally of the core within;

thecasing. This longitudinal movement of a portion of the surface of the core is prefer- .ably secured by forming the core of a supporting frame 105, which preferably itself forms a portion of the surface of the core and which carries at its outer end rolls 106 andv 106%.about which turn feeding-belts 107 and 107, which extend longitudinally of the core and turn `also about rolls 108 and 1082, supported in the frame 101 and on guide-rolls 109 `and 1092, also supported in the frame 101. The rolls 106 and 106 are preferably formed with their peripheries curved convexly, so as to cause the outside portions of the belts forming a portion of the periphery of the core "to take a corresponding forni. The guide-rolls 109 and 109 and the rolls 108 and 103iL also have their peripheries curved for the same? purpose, the peripheries of the guide-rolls 109 5 and 109i, however, being curved concavelyv The rolls 108 and 108 are geared together by gears 110 and aref` instead of convexly.

driven to drive the belts 107 and 1072, so that their outer portions shall move in a direction away from the frame 101 by'means of `a gear 111, through an intermediate 1112, meshingi with a gear 112 on the shaft of one of said rolls, said gear 111 being driven from a bevelgear 113, meshing with a bevel-gear 114, turnf ing with the gear 111, said gear 113 being carl ried by a stud 115, extending through the-end Fig. 7 is a view: taken on line 7 of Fig. 1, showing the wrapperwith gears 117 on the shafts of said guiderolls.

The casing 104 is cut away, so as to form an opening 4, as shown best in Figs. 1 and 5, through which the wrappers and the papers to be wrapped are advanced to the core. The wrappers y, which in the machine shown are wound about the papers in the form of acontinuous or unbroken web to form a continuous wrapper-tube about the core and the papers thereon, are guided to the space between the core and the casing at an angle to the core from a web-roll suitably supported, as by supports 120, carried by a frame 121, passing, preferably, between guide-rolls 122 and then turning downward over a guide-bar 123 and then beneath a guide-bar 124, said guidebars being supported by the frame 121 and extending longitudinally of the core. The guide-bar 124 lies preferably in position to guide the papers as they are advanced to the core, as hereinafter described, and to hold the papers in contact with the core, as shown in Fig. 5. As the wrapper-web advances to the core it receives a line of paste at one edge from a paste-roll 5, rotating in a fountain 6.

The papers a; are fed to the core transversely and entered between the core and the Wrapper-web preferablyin a direction at right angles lto the length of the core by means of feeding-tapes 125 and 126, turning on rolls 127 and 128 and 129 and 130, respectively, and are advanced to said feeding-tapes at proper intervals from a pile contained in a holder 131 by means ofareciprocating springpusher 132, by which the bottom papers are advanced successively beneath the edge of the front side of the holder, as usual in such constructions, the spring-pushers being carried by a sliding bar 133, which is reciprocated by means of rocking arms 134, rocked by an eccentric 135 through a rod 136, the eccentric being driven from a gear 137 on the main driving-shaft B, meshing with a gear 13S on the shaft carrying the eccentric. The rolls 127 and 129 carry intermeshing gears 139 and are driven from a gear 140 on the shaft carrying the eccentric 135 through'a train of gears141 142 143, the gear 143 meshing with a gear 144 on the shaft of the roll 129. The paste-roll 5 is driven from the shaft of the roll 12S as follows: The shaft of the pasteroll carries a belt-pulley 146, which is driven through a belt 147 from a pulley 14S, carried bya short shaft, which is driven from a gear 149 on the shaft of the roll 12S through a train of gears 150 and bevel-gears 151.

The operation of the parts thus far described is as follows: As the papers are ad vanced successively at the proper intervals by the feeding-tapes 125 and 126 the forward edge of each paper is entered between the wrapper-web and the core, as shown in Figs. 2 and 5, and each paper as it is engaged by thecore is further advanced by the rotation of the core and its rear edge drawn out of engagement with the tapes 125 and 126, the rolls 127 and 129 being positioned, preferably, at such distance from the core as to retain their grasp on the paper only long enough to insure the paper being fed into engagement la continuous spirally-Wound Wrapper-tube inclosing the papers and the core, the edges of each wrapper overlapping and being secured by the paste which has been applied at one edge of the wrapper. The papers as they are advanced to the core are preferably of such a Width as to extend substantially halfway around the core when bent about the core, so that when the wrapper-tube and inclosed papers are flattened the papers will substantially lill the flattened wrapper-tube. I prefer to time the rotation ofthe core and the feeding of the papers to the core relatively, so that a paper will be advanced to the core for each iive-eighths of a revolution thereof-that is, in the preferred construction shown the pusher 132 is reciprocated so as to advance a paper from the holder to the feeding-belts 125 and 126 for each ve-eighths of a revolution of the core, the papers being t-hus delivered from the belts to the core one for each five-eighths of a revolution of the core. The relative position of successive papers on the core will be understood from Figs. and 6. Supposing the forward edge of one of the papers to engage the core at H', as indicated in Fig. 5, then the forward edge of the following paper would engage the core at a point H2 in said iigu re when the core had made fiveeighths of a rotation to brin-g the point H2 in the position occupied in the figure by the point H. Similarly the next following paper would engage the core at the point H3, the one following that at the point H, and so on until eight papers had been advanced to and bent about the core, after which the next paper would again engage the core at the point H', the core making live complete revolutions for each eight papers advanced to it. Fig. 6 illustrates diagrammatically the position taken on the core by the successive papers as they would appear looking downward upon the core, the core being represented as extended for the purpose of showing papers in all the different positions on the core. The

successive papers in this figure marked :dwz ac3, rbc., correspond in position with papers whose forward edges engage the core at the points H H2 H3, &c., as indicated in Fig. 5. The core-belts 107 and 107 should be driven at such a speed, depending upon the length of the papers to be wrapped-that is, the dimensions of the paper lengthwise of the core as it is fed to the core-that each paper will be moved longitudinally of the core out of the path of the succeding paper as it is fed to the core, so that the successive papers as they are received on the core will not interfere. As the wrapper-tube is advanced with the inclosed papers beyond the casing 104 it is severed between the papers by a series of continuously-rotatin g segmental severing-blades 160, arranged about the path of the Wrappertube and inclosed papers and mounted to rotate in a plane at right angles to the axis .of the core. The several segmental blades are rotated together and timed so that their cutting edges move across the path of the wrapper-tube at' the same time, and during the time that the blades are moving across the path of the Wrapper-tube-that is, during the time in which they are acting to sever the wrapper-tube-the blades are moved in the direction of the movement of and at the same speed as the wrapper-tube, being for this purpose carried by a frame 161, mounted to slide on the casing 104 and on a stud 162. I preferably provide four such segmental blades, and in the construction shown, where the core makes only iive-eighths of a rotation for each paper wrapped, each blade will preferably be formed of a segment which forms two-fifths or a trifle more of a circle, and the blades are driven so that each blade makes one complete rotation for every iive-eighths of a rrotation of the core. The frame 161 is reciprocated to move the cutting-blades longitu-l dinally of the core by means of a cam-groove in a cam-cylinder 163, engaging a stud 164;,

on the frame, said cam-groove being formed so that when the segmental cutting-blades begin to sever the wrapper-tube they will be moving longitudinally with the wrapper-tube and so that this movement will be continued until the segmental blades have rotated out of the path of the wrapper-tube. Then during the time that the blades continue their rotation and before they again begin to move through the path of the wrapper-tube the frame is moved backward to its original position. The rotating and advancing wrapper-tube will thus be completely severed by the combined action of the several segmental blades moving with the tube and therefore acting to out the tube in lines at right angles to its length as it rotates and advances, each segmental blade cutting the tube for a portion of its circumference and the several cuts thus made by the different blades meeting to complete the severing of the tube. rlhe core preferably extends beyond the severing-point, as shown, and in order to prevent the feeding-belts 107 and 107a being cut by the severing-blades they preferably run beneath guards 165 and 165%, by which they are caused to move in a line out of reach of the severing-blades for a distance corresponding to the travel of the severing-blades lon gitudinally of the core in severing. The seg.-

mental severing-blades are preferably geared to rotate together by means of sprocket- Wheels 166, carried by the shafts of the several blades, and a sprocket-chain 167, turning on the several sprockets-wheels, and are driven from a gear 168 on the main drivingshaft B, which gear drives a gear 169 on the shaft of the lowermost of the cutting-blades through an intermediate 170. The intermediate 17 0 is a broad-faced gear, as shown, so as to engage the gear 169 While the vframe carrying the severing-blades reciprocates, the gear 169 in the construction shown being fast on the shaft of the lowermost cutting-blade and moving therewith. As it is necessary that the severing-blades shall extend only a little way into the path of the wrapper-tube, so as not to interfere with each other and so as to clear the core when the core is extended beyond the severing-point, it is necessary for the complete severing of the tube that the blades and the tube have a relative movement of rotation about the axis of the tube. This is provided for in the construction shown by the rotation of the wrapper-tube. It is evident, however, that if the tube did not rotate the same result would be secured by causing the severing-blades to rotate about the axis of the tube. The successive papers are thus delivered from the machine completely wrapped and separated from one another.
