Application filed December 8, 1899. Serial No. 739,598. (No model.)
To all whom it may concern.-
Be itknown that we, CLARENCE MILLHISER and CHARLES L. A. DOEPPE, citizens of the United States of America, and residents of '5 Richmond city, State of Virginia, have invented certain new and useful Improvements in Pouch-Machines, of which the following is a specification.
Our invention relates to pouch-making mai chines, and particularly to machines for making pouches which consist of more than one piece of fabric. In the following specification we shall describe a machine for making pouches of two different fabrics, such as are :5 commonly used for tobacco, but which machine can with slight modifications, which we will indicate hereinafter, be used for the manufacture of pouches consisting of more than two different fabrics.
In pouches made of two different fabrics the said fabrics are usually so arranged that one forms the upper and the other the bottom of the'po'uch. This is the usual form of two-piece pouches, though they may be constructed so that one fabric forms one side and the other fabric the other side of the pouch. We will first treat of the manufacture of pouches in which one fabric forms the upper and the other fabric the bottom, and also in which the upper is double.
The manner in which our machine operates to make pouches is, brie-flystated,'as follows: Two continuous strips of fabric are fed to a sewing mechanism, with their inner edges overlapping just so much that they may be sewed together. If it-be desired that no raw or unturned edges shall appear in the finished pouch, the outer edge of the strip of fabric which is to form the upperis then turned and creased. The upper fabric is now folded over, so that its outer edge lies upon the overlap between the two strips of fabric, and the fold is then creased. The united strips of fabric then pass to a double-headed sewing mechanism, which sews the outer edge of the upper tofthe overlap and at the same time runs a line of stitches at a short distance from the fold in the upper to provide a narrow channel for the draw-string. The united strips of fabric then pass to cutters which rounded.
sever from them portions each sufficient for the making of one pouch. The portions are now doubled'so that the severed edges of the strips are brought together, and the doubled portion is fed to a sewing mechanism or sewing mechanisms, which sew up one side and the bottom, the latter being either straight or The pouch is then ready for turning. The term doubling is here applied to the operation of folding the severed sections 'vage edge of the fabric will afford sufficient 7o finish. Again, it is not absolutely necessary that the sewing together of the overlapped inner edges of the strips of fabric should be the first anda separate operation, for the said edges can be sewed together by the doubleheaded sewing mechanism at the same time that the said sewing mechanism sews the outer edge of the upper to the overlapped inner edges, one stitching sewing the overlapped edges and the outer edge of the upper to- So gether. Again, if the upper is to have but little depth the line of stitches to formachannel for thedraw-string would'not be absolutely necessary, as the whole folded upper might then be used as the channel. Then, again, when a pouch having what is'termed asingieupper is desired all that is necessary is that the upper strip of fabric shall when it is folded ever be folded far enough to form a channel for the draw-string and not necessarily as far 0 as the overlapped edges of the two strips of fabric. In this case it is preferable to use one single-headed sewing mechanism to sew together the overlapped edges of the strips of fabric and another single-headed sewing 5 mechanism to sew down the fold of the upper to form the channel for the draw-string, and the folder for folding the upper would be so arranged as to fold under instead of over,
in order that the edge folded might lie on the Ice inside of the finished pouch,and consequently out of sight. Another way in which pouches having either double or single uppers may be made in our machine is to feed the strips of fabric to the sewing mechanism lying one upon the other instead of merely having the inner edges overlapping. The superimposed edges on one side of the strips are then sewed together. The upper one, which may form the upper of the pouch, is then lifted away from the lower strip of fabric, then folded longitu- (l iually, creased, the creased fold being finally sewed down. The strips are then ready to be fed to the cutters.
In the drawings which accompany and form a part of this specification and in which like numerals indicate like parts in the different views, Figure I is a plan of "the pouch machine. Fig. II is a side elevation of the same. Fig. III is a broken view showing in plan on a larger scale one end of the machine. Fig.

Fig. IX is a View in perspective of the edge turner or folder. Figs. X, XI, and XII are diagrams showingjthe approximate cross-sections of the turner or folder at the points 0, (l, and e in Fig. IX.
In Figs. I and II, 1 is the table, upon which the different operations are conducted. 2 is the main driving-pulley, mounted on the shaft 3, which is carried in bearings attached to the framework of the table. 4 is a shaft which receives its motion from the main shaft 3 by means of the bevel-gears 5. 6 is a countershaft which receives its motion from the shaft At the outer end of the counter-shaft (i is a crank 8, having an adjusting device whereby its throw may be regulated with accuracy and operating the connecting-rod 9, which by means of a rack cut at its farther end operates the in termittent silent feed mechanism 10, mounted on the shaft 11, which silent feed mechanism in its turn gives an intermittent motion by means of the shaft 11 to the lower feedrolI12. On the shaft 1.1, which carries the lower feed-roll 12, is a gear which gears into another gear of similar pitch and diameter 13, which is mounted on the shaft 14, which carries the upper feed-rolls 15. The motion .of the upper feed-rolls 15 will consequently be also intermittent and will be equal to the motion of the lower feed-roll 12. 16 is one of the strips of fabric, and it is being fed to the feed-rolls 12 and 15.
tomed pouch is desired it is necessary to cut Fig. V is an end elevation of designate by the numeral 32.
machine by means of the above-mentioned Now when a round-botor punch the fabric, so that when the pouch is finished it may have a bottom of the desired shape. Thiscutting or punching may be effected at almost any stage of the operationsfor instance, after the severed compound portion of fabric has been doubled, before the said portions are severed from the strips, or before the strips are' brought together. For the sake of convenience we prefer the first or last named stages, and in the drawings we have shown the punching as being effected in the latter stage.
Mounted on the shaft 3 are the cams 17, whose paths engage rollers attached to the lower 'ends of the rods 18, which slide in vertical sleeves 19. The upper ends of the rods 18 (see Fig. VIII) are connected with pins extending from the cross-bar 20, which crossbar slides in vertical grooves or guides 21. To the cross-bar 20 is attached a plate 22, which carries the punch or knife 23. Below the punch is a die 24, 'let into or forming a part of the table 1 and having around it an opening 25 to allow the pieces punched from the strip of" fabric to fall from the table. Every time the feed-rolls 12 and 15 operate they feed forward enough of the strip of fabric 16 for the manufacture of one pouch. As soon as the said rolls cease revolving the cams 17 cause the punch 23 to descend and to punch the edge of the strip of fabric to the desired shape, the punch immediately returning to its original position After leavingthe feedrolls 12 and 15 the strip of fabric 16 passes through a slot 26 in the table 1 and is drawn up again, passing between the guides 27 by means of the continuously-revolving feedrolls 28 and 29. (See Figs. I, II, VI, and VII.) The strip of fabric is allowed to pass through the slot 26 to accommodate the slack which must necessarily exist between the intermittent feed-rolls 12 15 and the continuous feed-rolls 28 29.
Hanging in bearings 30, which are attached to the frame of the machine, is a shaft 31, which carries a roll of fabric which we will This fabric leaving the roll is drawn around the rods 33 33 and between the guides 3t 34:, which are carried by the said rods 33, (see Figs. VI and VII,) and thence to the table 1 by means of the feed-rolls 28 29. The roll of the fabric 32 is so situated on the shaft 31 and the guides 34 are so placed on the rods 33 thatthe inner edge of the strip 32 will when it reaches the feed-rolls 28 29 be. overlapped by the inner edge of the strip of fabric 16.
IIO
the continuous feed-rolls 38 39. The continuous feed-rolls 28 29 and 36 37 and 38 39 are operated in the following manner:
The rolls 28, 36, and 38 are respectively mounted on the shafts 40, 41, and 42, which shafts respectively carry the sprocketwheels 43, 44, and 45. Around these sprocketwheels is passed a chain 46, which also passes around a sprocket-wheel 47, mounted on a counter-shaft 48, which receives its motion from the shaft 4 through the agency of bevelgears.
49 is a tightening-pulley adjustably attached to the bracket 50 and by means of which the sprocket-chain 46 can be tightened. As the shaft 4 revolves the sprocket-chain 46 will impart an equal motion to the roll- shafts 40, 41, and 42. Mounted on the said rolls are gear-wheels which gear with other gearwheels of similar pitch and diameter,-51, 52, and 53, mounted, respectively, on the shafts 54, 5 5, and 56, which carry the rolls 29, 37, and 39, respectively. Consequently all of the rolls 28, 29, 36, 37, 38, and 39 will havea uniform and continuous motion. 7
As the strips of fabric pass through the sewing mechanism the outer edge of thatone of them which is intended for the'up per of the pouch is turned down by means of the hem-turner 57, (see Fig. V1,) the turned hem being creased by the roll 36 and one of the rolls 37, and as the strips of fabric pass from the feed-rolls 36 37 to the feed-rolls 38 39 that one of them which is intended for the upper of the pouch is drawn through the folder 58, which folds the strip of fabric over, so that its turned outer edge lies on the overlapped inner edges of the two strips, the roll I 38 and one of the rolls 39 creasing the fold.
The form of the hem-turner 57 and of the folder 58, which are similar, the latter beingonlylarger than the former, is clearly shown in Figs. IX, X, XI, and XII, Figs. X,-XI, and XII being cross-sections v ta'ken, respectively, at the points 0, d, andein Fig. IX..
From the feed-rolls 38 39 the strips of fabric pass to the double-headed sewing mechanism 59, one needle of which sews the turned edge of the upper strip to the overlapped inner edges of the two strips, the other needle running a line of stitches at a short distance from the fold of the upper strip to provide a narrow channel for the draw-string. After leaving the sewing mechanism 59 the strips of fabric are fed by means of the intermittent feed-rolls 60 and 61 tothe cutters 62; but before reaching the said intermittent feedrolls the strips of fabric fall through a slot 63 in the table 1 and form a bight which is kept tight by means of the loose roller64, whose shaft runs loosely in the guides 65. The function of the roller 64 is to take up the slack which must necessarily exist in the fabric between the continuous rolls 38 39 and the inter- A similar roller may be mittent rolls 60 61.

29. (which are constructed and operated in a manner similar to that in which the intermittent feed-rolls 28 29 are constructed and operated) feed the strips of fabric under the blade of the shutters 62 and upon the doubling-table 66. (See Figs..III, IV, and V.) In this doubling-table there is a narrow slot 67, whose length is a little greater than the width of the united strips of fabric. Immediately beneath the slot are two rolls 68 and beyond these rolls two more rolls 69. Between these two sets of rolls is-a block or guide 70, whose function it is to guide the portions of fabric The intermittentfeed-rolls 60 and 61 as they pass through the rolls 68 to the grip of the rolls 69. The rolls 68 and 69 are operated in the following manner: The shafts on which the rolls 68 are mounted are geared together by means of gears of similar pitch and diameter 71, and the shafts which carry the rolls 69 are geared together in a similar manner by the gears 72. One shaft belong ing to each of the sets of rolls is extended and carries a sprocket-wheel numbered 73 and 74, respectively. Over these sprocketwheels there passes a chain 75, which also passes over and receives its motion from a sprocket-wheel 76, mounted on the shaft 42, which carries the continuous feed-roll (See Fig. I.) r
Above the sewing-table 7b a bracket 77 supports a lever 78, which carries at one end The other end of the lever 78 is connected by means of a link 80 to a rod ICC] 81, which slides in a vertical sleeve 82, the
which bears .upon the cam 84, mounted on the shaft 85. As the cam 84 revolves the rod 81 is given an upward and the blade 79 a downward movement. The return movement of the blade 79 is assisted by the spring 86. I The cutters 62 may be operated in any of the usual ways, a suitable one being that shown in the drawings. The cutting-blade 87 is attached to a cross-bar which is carried 1 by rods 88, which slide in vertical sleeves 89.
of this cam has teeth which mesh with the the cutters sever the said length from the strips of fabric. The center of this compound length or portion of fabric willlie immediately over the slot 67 in the doubling-table 66. The blade 79 now descends an'dpushes the center of the compound portion of fabric into the grip of therevolving rolls 68, which, pulling the fabric between them, double the two mechanism 95.
halves of the compound portion of fabric together. The doubled compound portion of fabric is'then fed by the rolls 69 to the sowing-table 76, where it is engaged by the transferring device 94 and advanced to the sewing We have not more fully described the details and operation of the transferring device 94, as we think they will be readily understood from the drawings, and also as they are fully described in an application filed by ns on October 11, 1899, and bearing Serial No. 733,260.
Sliding in a vertical sleeve 96 is a rod 97, which has a horizontal extension, carrying at its farther end a point or needle 98. The rod 97 carries at its lower end'a roller 99, which bears against a cam 100, which cam. gives to the rod 97 a vertical reciprocating motion, the downward movement of the rod being assisted by the spring 101. Now as soon as the sewing mechanism 95 has completed the sewing up of the side of the doubled compound portion of fabric the point or needle 98 descends and, piercing the fabric, arrests its progress. The feed-dogs of the sewing mechanism continue to feed the fabric onward, but since the fabric is held at one point this pointbecomesapivot around which the feed-dogs of the sewing mechanism turn the portion of fabric. Consequently the portion of fabric turning on a circle whose center is the point 98 the sewing mechanism will sew a line of stitches in a curve whose radius is equal'to the distance between the point 98 and the needle of the sewing mechanism. By varying this distance a varying curvature may be given to the bottom of the pouch. 1
