SPECIFICATION Vforming part ofV Letters Patent No. 622,841, dated April 11, 1899.

Application led June l, 1896. Serial No. 593,755. (No model.)

To ctZ whom t may concer-rt:

Be it known that I, LUTHER C. CROWELL, a citizen of the United States, residing at New York, (Brooklym) county of Kings, and State of New York, have invented certain new and useful Improvementsin Trapping-Machines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates especially to improvements in machines of that class used foi` applying wrappers to books, magazin es, pamphlets, folded newspapers, and similar articles, which articles will be hereinafter called papers,7 which term is to be understood as y meaning all articles on which a machine embodying the present invention may be found adapted to operate; but such machines are especially designed for use with magazines or other quite thick pamphlets.

More particularly the general features of the invention relate to a wrapping-machine of that class in which vthe wrapper is folded to form atube by means of longitudinal folders, the papers being placed in position and advanced with the wrapper before the edges of the wrapper are folded overy to complete the tube. In'V United States Letters Patent No. 516,186, granted to me March 13, 1894, I have described and claimed a machine of this class in which the sides of the wrapper are first bent downwardly and-,then turned back and folded over upon the paper lying on the middle portion of the wrapper. This reverse folding was for the purpose of causing all parts of the wrapper to travel the same distance, while at the same time Vproviding for the feeding of the papers into position to be enveloped by the wrapper as it is folded to form a tube. One of the objects of the present invention is to avoid this double or reverse folding of the wrapper in forming the tube, and this result is secured by so arranging the parts of the machine that the wrapper-tube shall be formed merely by folding the sides or edges of the wrapper up and then completing the tu be by folding down such upturned edges, the papers being fed into position to be enveloped by the wrapper as its edges are folded down to complete the wrapper-tube.

In carrying out the invention I preferably provide paper-feeding devices so located and arranged that the wrapper may be advanced with its upturned sides or edges on either side 5 5 of the feeding devices, and the means for turning up the edges of the wrapper andfor completing the folding o f the wrapper to form a tube are preferably separated, so as to leave a trongh-likespace between the upturned 6o edges of the wrapper long enough to accommodate suitable paper holding and feeding devices. By thus feeding the papers in the direction of movement of the wrapper into the trough' formed by turning up the edges of the 65 Wrapper the papers willbe fed forward on the wrapper after the operation of the paper-feeding devices ceases without the danger of slip between the wrapper and paper, which would exist if the wrapper started the movement of 7o the paper from a state of rest, this result being materially aided also by the pressure of the sides of the trough formed by the wrapper upon the side edges of the paper, so that the accurate positioning of the papers longitudiered between the papers, as a paper out of 8o position longitudinally of the wrapperis liable to be out by the wrapper-severing mechanism.

This invention includes, further, improved devices for operating, cutting, and similar blades especially adapted for use as a sever- 8 5 ing mechanism in a machine embodying' the other features of the invention, but which may also be used in machines of other classes.

For a full understanding of the invention a detailed description will now be given of a 9o complete Wrapping-machine embodying the various features 0f the invention in a preferred form, reference being had to the accompari ying drawings, illustrating such a machine, andthe features forming the invention will be afterward specifically pointed out in the claims.

In said drawings, Figure l is a side elevation ofthe machine, the near side of the frame being removed and parts being broken away. Ico

Fig. 2 is a partial plan view of the machineas shown in Fig. 1. Fig. 3 is an enlarged plan view of the paper-bending devices. Fig. 4is a section taken on line 4 of Fig. 3. Figs. 5 and 6 are enlarged cross-sectional views taken on lines 5 and 6, respectively, of Fig. 1. Fig. 7 is an enlarged plan view of the severing mechanism and adjacent feeding-rolls. Fig. 8 is a section taken on linev 8 of Fig. 7, and Figs. 9 and 10 are diagrammatical views showing different positions assumed bythe severing mechanism during the process of severing the wrapper-tube between the papers.

Referring to said drawings, the various parts of the machine are supported by side frames A B. The wrapper x is drawn from a roll mounted in bearings l0, at the'lower rear endl of the machine, over a roll 1l, where it receives a line of paste near one edge from a paste-disk l2, mounted to rotate in a pastefountain 13. The wrapper is then led upward past a roll 14 and over a roll l5 in the upper part of the machine, from which it passes downward to a longitudinal folder, by which its sides or edges are turned up to stand at about right angles with its central portion. This folder consists of an internal folder F, consisting of angularly arranged internal guides or turning edges 2l 22 and a horizontal guide or turning edge 23, connecting the lower ends ofthe guides 2l 22, external folders or turners 25 26 being also preferably provided. The edges of the wrapper are turned up about the guides 2l 22 bythe external turners 25 26, so as to stand at about right angles to the middle portion of the wrapper, which is turned about the horizontal guides 23, so that the now partially-folded wrapper advances in a direction at an angle to that in which it moved before, so that all parts of the wrapper travel practically the same distance, and therefore are held under the same tension, as is Well understood to be desirable in the art of folding paper by means of longitudinal folders having angularly-arranged internal guides. The folding of the wrapper to form a tube is completed by a pair of folding-guides 27 23, set at converging angles in a plane parallel with the plane in which the middle portion of the wrapper moves during and after the time at which it is acted upon by said folding-guides; but these horizontal folders 27 and 28 are placed some distance beyond the internal folder F and the external turners 25 and 26, so as to leave space between the point where the edges of the wrapper are folded up and the point where'the folding is completed for paper-feeding mechanism for feeding the papers onto the middle portion of the partially-folded wrapper.l

The internal folder F is preferably formed of a metal plate p, which is bent to form the guides 2l 22 23 and is preferably extended beyond the bent edges forming said guides to form the side plates 3l and 32 and bottom plate 33 of a trough or box about which the paper is advanced to the folding- guides 27 and 28 and in and above which are located paper holding and feeding devices constructed substantially as follows: The papers y are supported between the side plates 31 32 and a plate 35, forming the front of the paperholder thus formed, by a slatted bottom 36,

between the slats of which move paper-advancing lugs 37 on endless belts or sprocketchains A38, by which the papers are fed forward beneath the front plate 35,which is of the proper length to allow one paper at a time to be fed forward beneath it. The two outside slats sof the bottom 36 are extended backward and are supported 'by depending arms 39 40 from cross-bars 4 1, extending between the sides of the machine above the side plates 3l 321, so as to clear the upturned edges of the wrapper as it passes through the machine.

The sprocket-chains 38 turn on sprockets 43 and 44, carried by shafts 45 and 46, respectively journaled in the outside slatss of the bottom 36, and are driven from a shaft 47 through an intermediate 48, meshing with a gear v49 on the shaft 47 and with a gear on the sprocket-shaft 46. The slats forming the bottom 36 are set at an angle to the bottom plate, and for the sake of economizing space preferably extend only a little past the middle of the length of the papers as they lie in the holder, the sprocket-shaft 45 being mounted near the forward end of the bottom.

As the paper is fed forward from the paperholder its forward end drops to the bottom plate 33 and on its farther forward movement is engaged bya feeding-roll 50, which is carried by arms 5l, depending from a crossbar 52, extending between the side frames of the machine above the side plates 3l and 32, so as to clear the upturned edges of the Wrapper, and which roll is driven from a transverse shaft 53 through an intermediate 54 on a stud carried by one of the arms 5l and meshing with a gear 55 on. said shaft and with a gear on the shaft of the roll 50. The shaft 53 is journaled in the side frames and extends'across the machine above the side plates 3l and 32 and the upturned edges of the wrapper. A feeding and supporting roll 56, carried by a shaft journaled in brackets 57, mounted at either side of the machine, coacts with the roll 50 frornbeneath, the bottom plate being cut away, as shown, so that the paper comes directly in contact with the middleportion of the wrapper at this point, and the papers and wrapper are fed forward by means of these rolls 50 and 56, bearing respectively against the upper side of the paper and the underside of the wrapper. Then as the wrapper is farther advanced through the machine with the papers placed successively in position over its middle portion the folding of the wrapper to form the wrappertube is completed, the edges of the wrapper being turned down over the papers by means 'of the horizontal folding-guides 27 and 2S.

The side plates 3l and 32 terminate justin the rear of the folding-guides 27 and 2S, the ends of the plates forming internal supporting and bearing guides or edges 61 62 for the IOO IIO

wrapper as it is turned inward and downward by the guides 27 and 28. The ends of the plates are preferably turned or rounded slightly inward, so as to provide rounded bearing-guides, as shown in Fig. 2. From the point where this second part of the folding operation begins the wrapper is advanced in 'a direction at a slight angle to that in which it moved beneath the bottom plate 33, this angle and the angle at which the horizontal guides 27 and 28 are set and the inclination of the internal guiding edges 6l and 62 being relatively such that each part of the wrapper will travel the same distance.

For the purpose of securing a tight fit of the wrapper about the paper there is preferably provided a suitable conforming device for bending the paper transversely at the time the wrapper-tube is being formed about it, so that 4the distance around the paper at that time will be slightly less than the distance around it when it is in a flat position. For this purpose there is provided in the machine illustrated in the drawings a float 70, having its upper surface plane and its lower surface curved transversely, so th at itshall be planoconvex in cross-section, the bottom surface of the float being also tapered upward at each end. The papers as they are advanced upon the middle portion of the wrapper pass beneath this oat, while the edges of the wrapper are turned down upon the upper surface thereof, and the paper is bent up at its edges, so as to conform to the curved under surface of the float, by means of guides 71 72 at either side, which guides are preferably curved to correspond with the curve of the under surface of the iioat and provided with upwardlyextending edge-guiding side iianges 73 74. The float is supported at its rear end by depending arms 75 from a cross-bar 76, extending between the side frames A B above the upturned edges of the wrapper.

Feeding-rolls 7S SO engage the under side of the middle portion of the wrapper between the guides 71 72. A feeding-roll 79, carried by depending arms 82 from the cross-bar 76, coacts with the feeding-roll 7-8,aeting, through an'opening in the ioat 70, to engage the uppersurface of the papers as they are advanced beneath the forward end of the float, and a feeding-roll S1 engages the upper surface of the edges of the wrapper after they have been turned down over the iioat.

As the wrapper-tube, with the inclosed papers, advances beyond the eonformin g device it is engaged by a pair of feeding and pressing rolls S4 and S5, by which the papers are flattened, which causes the wrapper-tube to be drawn tightly about the papers. A pair of final feeding and pressing and delivery rolls SG and S7 are preferably provided beyond the rolls S4 35, suitable severing mechanism being preferably provided to sever the wrappertube between the successivel papers as they are advanced from the rolls 84 S5 to the rolls 36 87.

ening the bending or conforming device to such an extent as would otherwise be necessary to allow the seam to dry sufficiently to withstand such a strain before the papers are flattened. For this purpose there is provided inthe preferred construction shown a steampipe-90, having a flattened surface extending for a sufficient distance just above the oat beyond the folders 27 and 23 to cause a sufficient drying of the pasted seam as it is advanced beneath and in contact therewith. This drying-pipe preferably extends down around the rear side of the shaft of the roll 81, then forward beneath said shaft, and up in front of the shaft of the roll 85, the rolls S1 and 85 being cut away, as shown in Fig. 3, to accommodate said pipe. In order that the seam of the wrapper may be held in contact with the under surface of the steam-pipe as Lthe wrapper is advanced beneath it, the upper surface of the fioat 70 is cut away beneath the steam-pipe and one or more springs 91 are provided to bear againt the underside of the wrapper-seam, which springs hold the seam against the under side of the pipe without causing unnecessary friction between the wrapper and steam-pipe, by which the movement of the wrapper would be retarded. rlhe steampipe may be connected by any suitable connections with a suitable steamsupply.

The machine is preferably provided with means for cutting the wrapper-tube between the successive papers as the tube, with its inclosed papers, is' advanced from the wrapping devices. Any suitable severing device may be employed for this purpose.v I have shown a convenient form of severing mechanism, which in itself constitutes a feature of the invention and which in the preferred form is constructed substantially as follows:

Coacting severing-blades and 101 are carried by shafts 102 and 103, respectively, one above and one below the line of movement of the wrapped papers. I is carried by bracket-s or carriers a a at either side of the machine. The carriers d are each carried by two equal and parallel crank-arms b, each of-which crank-arms b is carried by a stud c, journaled in the side frame of the machine, and each of which studs is provided with a gear d. Intermediates e connect the gears d of each pair of studs c, and each pair of studs is driven from a gear f on the shaft of the roll S4 through an intermediate g, meshing with one of the gears d of each pair, whereby the cranks l), carrying the brackets d, are caused to rotate in unison. The carriers a a and the severing-blade 100, carried thereby, are given a rotary movement of constant parallelism, being moved through a cir- IOO IIO

The shaft 102 tained constantly in a vertical position while being moved through a course which carries it into the path of the horizontally-moving papers. Similarly the shaft 103 is carried by brackets or-earriers c et at either side of the machine, and these carriers are each carried by two equal and parallel crank-arms b', eac-h of which crank-arms b is carried by a stud c, journaled in the side frame of the machine, and each of which studs is provided with a gear d. intermediates e connect the gears d ofl each pair of studs c', and each pair of studs is driven from a gear f on the shaft of the roll 85 through an intermediate g', meshing with one of the gears d of each pair. It will thus be seen that the cranks carrying the carriers a ce and a a being caused to rotate A in the proper directions, as indicated by arrows in Figs. 8 to 10, and at the proper speed the severing- blades 100 and 101 will be given a circular movement, whereby when they I they may have a slight movement longitudinally of the movement of the papers against a yielding tension by which they are held in their normal positions. For this purpose the shafts 102 103 are preferably pivotally mounted in their carrying-brackets a a and a a', respectively, and are held so as to maintain the blades in their normal vertical positions, preferably by means of centering-springs 91, extending in either direction from arms 104 and 105 on the shafts 102 and 103, respectively, to the brackets a and a', respectively. The severing-blades are thus free to yield slightly if struck by the end of the paper.

The action of the severingblades constructed as above described will be readily understood by reference to Figs. 8, 9, and 10, Fig. 8 lshowing the position of the severingblades and their supporting parts as the blades are just coming in contact with the v wrapper-tube between two successive papers,

of their normal vertical positions by lthe forward end of one of the papers on account of the horizontal or longitudinal movement of the blades at this point being less than that of the papers.

It is evident that the means for securing the desired movement of the severing-blades, as above described, may vary -greatly from that shown. Thus instead of the blades being mounted in brackets which are each carried by two equal and parallel crank-arms, as in the construction shown, they maybe rotatably mounted in single crank-arms or in a cylinder and controlled by suitable gears to maintain them in positions of constant parallelism during their movement of rotation in the manner well understood for obtaining the desired rotary movement of constant parallelism. It is to beunderstood, therefore, that any other suitable means than that shown may be used for securing the desired movement of the severing-blades. rlhe means shown, however, is preferred and in itself forms a feature of the invention.

The wrapped and severed papers may be delivered by the rolls 86 and S7 to any suitable receptacle or onto a suitably-arranged carrying-belt, by which they may be carried to a convenient receptacle. I have shown them as being delivered upon such a carrying-belt 95.

The various moving parts of the machine are driven from a longitudinally-arranged driving-shaft 110, said shaft carrying beveled gears 121 122 123, engaging beveled gears 131 132 133 on the ends of the shafts of the rolls 87 85 S1, respectively. The shafts of the rolls 86, 84, and carry gears meshing with gears onv the shafts of the rolls S7, 85, and 81,' respectively. The shafts 53 and 47 are driven from an inclined longitudinal shaft 111, carrying beveled gears 124 and 125, engaging beveled gears 134 and 135 on the ends of said shafts, said shaft 111 being driven from the shaft 110 through beveled gears 123, 133, and`112. The shaft of the roll 56 is driven from a gear l113 on the transverse shaft 53, through intermediates 114 and 115, the gear 115 meshing with avgear 116 on the shaft of the roll 56, and the shaft of the roll 78 carries a gear 117 and is driven from the gear 113 on the shaft 53, through the train of gears 114, 115, 118, and 119.

lIt will be understood that many modifications may be made in the construction shownwithout departing from the invention and that the various features of the invention may be embodied in machines diering widely in construction and method of operation from that shown.

My improved severing mechanism may be employed wherever it is desired to cut moving tubes or other papers orbodies, being especially useful where it is necessary to cut through a considerable distance, as in the case of severing a wrapping-tube between the articles wrapped. Certain features of this ICO IIS

mechanism may be usedalso with blades used for other purposesthan cutting, such as folding-blades and tucking-blades, andA it will be understood that the claims which are not limited to any particular class of blades are intended to cover such uses.

By the phrase rotary movement of constant parallelism used in the claims to define the movement of the severing-blades I mean that the severingblade is moved through a circular path while occupying at all periods of its movement positions substantially parallel with its original positions or remaining constantly parallel with a given plane.
