SPECIFICATION forming part of Letters Patent No. 587,929, dated August 10, 1897.

Application filed September 19, 1896- Serial No. 606,348. (No model.)

To all? whmn it may concern.-

Beit known that I, EDWARD E. CLAUSSEN, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Paper-Bag Machines, of which the following is a full, clear, and exact specification.

This invention relates to machinery for automatically manufacturing paper bags from tucked-paper tubing, and, as herein shown and described, is especially adapted for in anufacturing such bags in accordance with the method set forth in reissued Letters Patent No. 10,083, although portions of this machine are also susceptible of use in other methods.

The object of this invention is to provide a machine that is reliable in its action for forming the most intricate part in the manufacture of square-bottomed paper bags from bellows-sided tubing, which is the forming of the well known diamond form preparatory to pasting, folding, and closing the two end flaps and thus completing the bag.

The mechanisms herein shown and described have the folding-beds represented as supplemental carriers which are pivoted to revolving cylinders on pivots beyond the pa per-bag blank and adapted to swing away from the cylinder, and arranged in pairs, the one member of the pair being on one side of the paper-bag blank and the other member of the pair being on the other side of the paperbag blank. These supplemental carriers are provided with front clips and also with side grippers, the latter adapted to enter into the tucks and provided with beveled edges acting as formers for aiding in defining the characteristic right-angled triangular folds during the unfolding of the blank into the diamond form.

The invention will best be understood as described in connection with the drawings in which it is illustrated, and in which Figure 1 is an outside view, partly in section, taken on line 1 1 of Fig. 3 and showing principally the arrangement of the gearing which drives and transmits the motion to the various mechanisms. Fig. 2 is a sectional side view taken on the broken line 2 2 of Fig.

3, showing the drawing-rolls that draw the tubing from the tube-forming mechanisms, it being understood that the same is produced by any of the well-known methods. The blank in the machine is representedin a position to be severed from the continuous tube and being clamped by the front clip to the supplemental carriers and ready to have the subsequent folding operations performed thereon, also showing at the left end of the machine a part of the broken-away former. Fig. 3 is a plan view, partly in section and taken on the broken line 3 3 of Fig. 2. Fig. 4 is a cross-sectional end view taken on line 4 4 of Fig. 2 in the direction of the arrows. Fig. 5 is a rear end view of the right-hand side of the machine as represented in Fig. 1, omitting the folder-plate 70. Figs. 6 and 7 are respectively fragmentary side and end views of the folding mechanisms in aposition where the bottom-forming end of the bagblank is partly opened. Figs. 8 and 9 are respectively fragmentary side and end views of the folding mechanisms in a position when the diamond form is completed.

In the following specification, of which the accompanying drawings form a part thereof, similarnumerals of reference designate like or equivalent parts wherever found throughout the several views, and in which- The numeral 20 designates the bed of the machine, which supports on' each side the up- c rights 21 and 22, in which the various shafts and mechanisms are journaled, as hereinafter more fully described. Motion is communicated to the machine by means of the pulley 23, driven in the direction of the arrow 24:, (see Fig. 2,) fastened to the shaft 25, which is journaled in the uprights 21 and 22, and carries on the outer side of the upright 21 the gear 26. The gear 26 meshes into the gear 27, fastened to the shaft 28 and driving the train of gears 29, 30, 31, 32, 33, and 34:, some of which have fragmentary portions broken away and which are respectively mounted on the studs or shafts 29, 30, 3l, 32, 33, and 34". The

stud 29 is fastened into an arm 29 and piv- The shafts 31 32 33 34 are all journaled cylinders by the shafts 56 and 57, the free in the uprights 21 and 22 and have fastened thereto the lower front drawing-roll 31, the upper front drawing-roll 32", the lower rear drawing-ro1l33", and the upper rear drawingroll 34, respectively. The gear 27 has a projecting lug 27 on its outer face, to which is pivoted the sector 37, meshing into the sector-pinion 38, which is integral with the hub of the gear 39 and rotatably mounted on the stationary sleeve 40, driven into the stationary bracket 41, the inner projecting end of the sleeve carrying a cam 40, into the outer circumference of which is cut the cam-groove 40, into which engages a projection 37 of the sector 37. By themechanisms just described the gear is uniformly rotated, carrying along with it the sector 37, the sector-pinion 38, and the gear 39, and as the projection follows the cam-groove it throws the sectors 37 and 38 back or forward, and thus the rotation of the gear 39 is retarded, accelerated, or revolves in unison with the gear 27, according to the timing of the cam-groove, The gear 39 meshes into the lower cylinder-gear 42, fastened on the shaft 43, and said gear meshes into the upper cylinder-gear 44 on shaft 45, journaled in the uprights 21 and 22. The shaft 45 has fastened thereto directly beyond the outside of the upright 22 the bevel-gear 46, meshing into the bevel-pinion 47 and fastened to the striker-shaft 48, which is journaled in a hub 22, integral with the upright 22, and carries clamped thereto the striker-arm 49, which revolves across the path of the tube, carrying it against the serrated knife 50, and severs a blank at each rotation. The gears 31 32 33 34, with their corresponding rolls 31 32 33 34", are so geared in relation to the striker-arm 49 that to each revolution of the striker-arm a suitable length of tubing is drawn forward of sufficient length to make the body and the bottom-forming end of the bag-blank.

By the means above described a continuous motion is transferred from the driving mechanisms to the drawing-rolls and the striker-arm and the tucked-paper tube severed into bag-blank lengths and delivered to the bottom-forming mechanisms to perform their respective functions, as will now be explained.

The rod 51 is driven into the uprights 21 and 22 and carries the supporting-plate 51, which guides the blank from the drawingrolls to the cylinders. Fastened to the shaft 43 is a cylinder 52, and fastened to the shaft 45 is the cylinder 53, which are located oppositely of one another and are substantially alike and provided With the sector-like mutilations 52 and53, respectively, and which are adapted to be covered by the flat or straight surfaced . carriers 54 and 55, forming flat surfaces on the cylinders when the same are in their normal position, as shown in Fig. 2. In the drawings I have shown two of these carriers pivoted to each cylinder, which are similarly. mounted and are pivoted to the ends of which are attached to cam- arms 58 and 59 and adapted to'engage the stationary cams 60 and 61, mounted on the projecting hubs 21 and 21 of the upright 21. The springs 62 keep the cam-arms in engagement with the cams, which are of such shape that as the carrier is carried around by the rotation of the cylinder the carrier is caused to be oscillated to a tangential position in relation to the cylinder and then returned to its normal position, as clearly shown in the drawings in Figs. 2, 6, 7, 8, and 9. The swinging free end of the carriers 54 and are preferably beveled oif, as at X and Y, so as to give a sharp folding-line in defining the primary transverse folding-line across the bag-blank.

The carriers 54 and 55 are provided with front clips 64 and 65, fastened to shafts 66 and 67, their outer free ends being provided with cam- arms 68 and 69, engaging the stationary cam-pieces 72 72 73 7 3, respectively. Springs 74 keep the cam-arms and their clips in engagement with the carriers. The timing of the cams 72, 72, 73, and 73 is such, in relation to the rotation of the cylinder and the severing of the blank by the rotation of the striker-arm, that the front clips are caused to be opened by the cams 72 and 73 as the leading end of the blank advances and caused to be closed and clamp the outer plies of the tube to the carriers, as shown in Fig. 2. front clips to release the blank when the diamond form is completed. The carriers are also provided with two pairs of bevel-edged side clips-that is, with each front clip is coacting one pair of oppositely-disposed beveledged side clips 76 and 77, pivotally mounted on pivots which are fastened in hubs 54 and 55 beneath the folding-surface of the fiat carriers.

The side clips are held in an open or closed position by the springs 79 pressing on the pro-- jections 78 and which are mounted in the spring-casings 80 in the Well-known manner. The side clips 76 and 77 are operated by projections 76 and 77, projecting therefrom, and are caused to be operated by cam-pieces S2 82 83 83 as the cylinder carries them onward in such a manner that the cam- pieces 82 and 83 cause to close the side clips into the tucks of the blank and to be released at the proper time, when the diamond is completed by the cam- pieces 82 and 83. The campieces 82 S3 82 83 are fastened on the righthand side of the machine to the cams and 61 and on the left-hand side to the flanges 81 and 81, provided with hubs that are mounted to the frame 22. The location of these campieces in relation to the rotation of the cylinder is such that the bevel-edged side clips are caused to be closed simultaneously or a. little after the front clips have been closed, and to carry the blank onward while the coacting pair of carriers are carried or vibrated The cam- pieces 72 and 73 open the- ICO into a tangential position with the cylinder,

as best shown in Figs. 6, 7, 8, and 9, and thus distending the tucks and unfolding the wellknown inside triangular folds, and the edges of the carriers defining the primary transverse folding-line across the tube and converting the tubular blank into the diamond form. As the carrier rocks from its outward position back into the normal position the formation and the flattening of the diamond is aided by pressing the blank against the stationary folder-plate 70, which is fastened on a rod 71 and mounted in the uprights of the machine.

After the diamond is completed the paste is applied by the sector 85, fastened to the shaft 86, journaled in the uprights 21 and 22 and carrying on the outside the gear 87, which meshes into the cylinder-gear 42. The sector is supplied with paste from a roll 88, which turns in a paste-box S9 and receives a rotary motion by the belt 90, driven from any convenient shaft, in this case from the shaft 100. The gear 87 is geared with relation to the cylinder-gear 42 in such a manner that the face of the sector is presented to the cylinder twice to every revolution of the cylinder, and in this manner the paste is deposited at regularintervals to the bag-bottoms as they pass along and the flaps folded in any of the wellknown manners.

The operation of the machine is as follows: The paper is taken from a roll and folded by any of the wellknown mechanisms (not shown in this application) into a tucked tube and drawn between the rolls 31 and 32 under the serrated knife into the machine and the blanks severed from the continuous tube by the striker l9, revolvin across the path of the tube and forcing it against the serrated knife and severing the blank therefrom at each revolution. The drawing-rolls are so geared with relation to the revolution of the striker as to feed through a suitable length for each revolution thereof. The tube is supported in its travel from the drawing-rolls to the carriers by the plate 51, and as the bottom-forming end approaches the bottom-forming mechanisms the coacting pair of carriers 54 and 55 are in their normal position and as the cylinder revolves, the front clip as well as the side clips are opened by the cam-pieces '72 73 and 82 83, respectively, and the tube enters into the bite of the same, and then the clips are closed, thus holding the lower ply of the tube and the lower plies of the tucks to the lowermember of the coacting pair of carriers and the upper ply of the tube, together with the upper plies of the tucks, to the upper member of the coacting pair of carriers. The cylinders revolve at this point with the uniform speed, and as they approach the position indicated in Figs. 6 and 7 the speed is retarded by the action of the sector 37 and its projection 37, engagingin the cam-groove 40, to give the carriers time to be carried from the normal position into the tangential position, as shown in Figs. 8 and 9, the folding edges of the carriers thus defining the characteristic primary transverse foldingdines across the-tubular blank, and thus unfolding and forming the well-known inside triangular folds and passing through the. positions as shown in Figs. 2, 6, and 8 and converting't-he tucked-paper tube into the well-known diamond form, which may then be flattened by pressing the carriers against the folder-plate 70. As the cylinders continue to revolve the bevel-edged side clips and the front clip of the upper member of the pair of carriers are caused to be opened by the cam- pieces 83 and 73, thus releasing the blank therefrom, the lower member of the pair of carriers retaining its hold until the paste applied and the remaining flap-folding instrumentalities are ready to operate thereon, and simultaneously the front and the side clips of the lower member of the pair of coacting carriers are released, and the blank is then pressed and packed.

In this class of machines where a cylinder is employed as the folding-bed the unfolding of the blank is done on a curved surface, which is the cause of a great many distorted bags, and the important feature of this invention, therefore, is the arrangement of using fiat folding-surfaces and still employing, as a means for propelling, a conveyer in the form of a cylinder.

In the drawings I have shown the cylinders as being of the same diameter and both being provided with two carriers; but it is understood that this is not at all necessary, as one cylinder could be arranged for with two carriers, whereas the other be only arranged with one carrier, in which case the two-bag cylinder revolves once to every two revolutions of the one-bag cylinder.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a paper-bag machine the combination of two oppositely-disposed continuously-rotating cylinders, each cylinder having a supplemental carrier pivoted thereto, operating means to simultaneously impart a vibratory motion to each member of the carriers to bring them in substantially the same plane during the forward movement of the cylinders and devices cooperating with the carriers, to hold and define the corners of the bag, all combined and operating to convert the tuckedpaper tube into the diamond form, substantially as described.

2. In a paper-bag machine the combination of two cylinders supported for continuous rotation, and in substantially parallelism with one another, each cylinder having a supplemental carrier pivoted thereto, and also in substantial parallelism with the shafts of the cylinders, operating means to simultaneously impart a vibratory motion to each member of the carriers to bring them in substantially the same plane during the forward movement of the cylinders, devices cooperating with the ICC , carriers to hold and define the corners of the rotation, and in substantial parallelism with another, each cylinder having a fiat supplee one another, each cylinder having a supplemental carrier pivoted thereto, and forming flat folding-surfaces on the cylinders, mechanisms to oscillate the carriers upon theirpivots, means upon the carriers to hold and define the corners of the blank, while the carriers are oscillated outward, and the cylinders rotated forward substantially as described.

5. In a paper-ha g machine the combination of two cylinders supported for continuous rotation, andin substantial parallelism with one mental carrier pivoted thereto, mechanisms to simultaneously oscillate the carriers on their pivots to bring them outward into the same plane while the cylinders are moving forward, the oppositely-disposed bevel-edge side clips and the front clips with means for imparting an oscillatory motion thereto at predetermined intervals to hold and clasp the blank, while the cylinders move forward and the carriers oscillate, and the edge of the carriers form the primary transverse foldingline across the blank substantially as described.

6. In a paper-bag machine the combination of two cylinders supported for continuous rotation and in substantial parallelism with one another, each cylinder havinga flat supplemental carrier pivoted thereto, mechanisms to simultaneously oscillate the carriers on their pivots to bring themoutward into the 5 same plane while the cylinders are moving forward, the oppositely-disposed bevel edged side clips, and the front clips with means for imparting an oscillatory motion thereto at 1 predetermined intervals to hold and clasp the blank, while the cylinders move forward and the carriers oscillate, and the edge of the earriers form the primary transverse foldingline across the blank, the whole operating to convert the tucked-paper tube into the diamond form and press to flatten the same against the folder-plate substantially as described.

7. In a paper-bag machine the combination of two cylinders supported for rotation and in substantial parallelism with one another and provided with mutilations, supplemental carriers covering said mutilations when in their normal positions and forming flat folding-surfaces on the cylinders, means to simultaneously oscillate the carriers from the normal position into the position that the fiat surfaces of the carriers form substantially one plane during the forward movement of the, cylinders, the bevel-edged side clips pivotally mounted to the carriers and adapted to be oscillated into the tucks of the blank, and the front clips to hold the plies of the tube to the carriers, all combined and operating to unfold the tucked-paper tube into the diamond form, while the end of the carriers define the primary transverse folding-line across the bag-blank substantially as described.
