An object of the invention is to provide tilled bag closing machine of the above type,

wherein both the conveying mechanism and the stitchingmechanism are capableof vertical adjustment, and means is provided for vertically adjusting the conveying mechanism and stitching 11160113111811! independently of each other or simultaneously toward and; from each other.

A further object of the invention is to'provide a, filled bag closing machine, wherein the sewing head is capable of vertical adjustment and wherein said sewing headis driven by a motor which moves vertically with the sewinghead.

A still further object of the'invention is to provide a filled bag sewing machine wherein Another object ofthe invention is to provide a filled bag sewing machine'wherein the carri age carrying the filled bag and present ingthe' same to the stitching mechanism is moved by hand along tracks disposed substantially horizontally, which tracks are. capable of being adjusted vertically relative to the sewing head for positioning the carriage for different size bags.

Another object of the invention is to provide a filled bag sewing machine having a traveling carriage with a stop mechanism for normally holding said carriage in position where the bag may be placed thereon prior to the presenting of the same to the stitching mechanism and wherein said stop mechanism is automatically released when the bagis placed on the carriage. I

The invention is applied to a filled bag sewing machine of the type wherein the filled bag is placed on a carriage capable of traveling back and forth on tracks. These tracks are mounted on a supporting frame so that they may be adjusted vertically. The sewing head is alsomounted on the same supporting frame so as to overhang the traveling carriage and said sewing head is also capable of being adjusted vertically. The same bracket which supports the sewing head also supports the motor for driving the sewing head. A vertical screw shaft is provided for adjusting the sewing head vertically on the frame and Means is provided whereby the screw shafts may be independently rotated or simultaneously rotated. This enables the, sewing head and the traveling carriage to be quickly moved toward or from a given point simultaneously or the operator may movethe sewing head independently of 'the supporting carriage and, again, the operator may move the supporting carriage independently of the sewing head. This enables the machine to be readily adapted for operating upon bags of various'sizes and at the same time maintain the stitching level so that it wi-llbe very convenient to the operator.

As noted above, the sewing head and the operating motor are shiftable together vertically. The stitching mechanism is controlled by a lever which is also mounted to move bodily with the sewing head. The distance of this lever from the floor will, therefore, vary as the sewing head is shifted. A treadle is mounted on t-he supporting base of the machine, whereby the sewing head is controlled and in orderto take care of the vary ing heights to which the sewing head may be placed, automatic means has been provided forming a part of the controlling means which automaticallycompensates for the different heightsto which the sewing head may beset. This compensating means consists broadly of 'a rotatable part having a flexible connectionwith theicontrolling lever of the sewing head. A weight is also attached to this rotatable part by a flexible supporting means. and the weight normally tends to rotate the part so as to wind up the flexible connection extending to the controlling lever of the sewing head. This weight when the rotatable member is free will take all the slack out of the flexible connection to the controlling lever. A treadle is connected to an operating lever which when depressed will clutch up with the rotatable part and positively turn the rotatable part so as to actuate the controlling lover.

The invention will possibly be better understood by a more detail description of the apparatus shown in'the drawings which illustrate one embodiment of the invention.

In the drawings, the machine is shown as consisting of a supporting base 1, centrally of which is a vertical column 2. This vertical column may be formed of a hollow cy- V lindrical pipe which is of sutficient strength to supportthe parts and yet not of excessive weight. Extending out from the support ing base 1 are four substantially horizontally disposed legs 3, each ofwhich is provided with a castor or supporting roller 4 which is connected to the leg so that said castor or roller may readily turn to'accommodate the direction in which the apparatus is to be moved. Extending from two of the legsare bolts 5 which may be adjusted vertically and secured in adjusted position by means of a lock nut 6. These bolts may be used to level the machine and securely hold the machine from movement when it is brought to a desired position for use. The legs 3 are made of angle iron and these angle iron sections are bolted to the supporting base 1. Brace rods 7 are also bolted to the vertical portions of the angle irons forming the legs and this makes up a skeleton supporting portion for the apparatus which is strong and durable; also which is light and which can be very cheaply made.

At the upper end of the column 2 there is an adjustable bracket 8. Said bracket is formed in part by a sleeve 9 which slides freely on the column 2. Said sleeve has formed integral therewith a forwardly project-ing support 10. The sewing head is indicated at 11. Said sewing head is bolted to a plate '12 formed as a part of the support 10. The sewing head is of the usual construction. Said sewing head has a needle bar 13 carrying a needle 1% and the needle bar is reciprocated by means of a needle lever 15, which needle lever is in turn oscillated by an eccentric strap 16, co-operating with an eccentric-on the main shaft 17. The machine also includes a suitable presser foot 18, and feed dog 19 which is actuated in the usual manner from the main shaft for intermittently feeding the mouth of the bag step by step to the stitching mechanism as it is stitched. There is also mounted in the cylindrical arm 20, "besides the feeding mechanism, complement-a1 stitch forming mechanism which 'co-operates with the needle in forming the stitches. This sewing head may be of any desired construction and further description thereof is not thought necessary.

Also, extending laterally from the sleeve 9 is a second supporting member 21. This supportingv member 21 is on the opposite side-of the sleeve from the supporting member 10. A motor 22 for operating the sewing head is secured to a plate 23 which is bolted by means of bolts 24 to the support 21. The motor is secured to this plate 23 by bolts 25 25. It will be noted that the motor is on the oppositeside ofthe column from the sewing head and therefore in a sense counter-balances the tendency of the weight of the sewing head to cause the sleeve to bind on the column so that the sleeve will more smoothly move up and down on the column. The plate 23 may be adapted to different sizes and s his of motors.

Also extending out from the sleeve 9 is a support 26 in which is mounted a'transmitter for transmitting power from the motor to the sewing head. Thiszsu'pport 26 consists of an upper arm 26 and a lower arm 26. Journale-d in these arms is a shaft 27. Mounted on the upper end of'the said shaft 27 is a groove pulley 28. The groove pulley '28 is adapted to be belted by means of a belt 29 to a belt wheel 30, on the main shaft 17 of the sewing head. Also fixed to theshaft 27 is a combined clutch and brake disk 31. On the under face of said disk 31 there is a flexible facing 32 which is adapted to be engaged by means of a belt wheel 33 which is free on the shaft and capable of endwise movement on the shaft. This belt wheel 33 is connected by means of a belt 34 to a belt wheel 35 on the motor shaft so that when the motor is running the belt wheel 33 is continuously operated. A spring 36 normally presses the belt wheel 33 away from the facing 32 of the disk 31, so that these parts are disengaged and while disengaged the loose belt wheel willrun freely without in any way turning the shaft 27. g As a means for bringing the loose belt wheel into driving contact with the disk 31, a controlling lever 37 has been provided. This controlling lever 37 is pivotally supported by the bracket 8 so as to swingin a vertical plane and said lever carries a forked arm 38 which straddles the shaft 27 and. is adapted to move the belt wheel 33 endwise on the shaft. A ball bearing 39 is locatedbetween the end of the forked arm 38 and the belt wheel 33. There is also a ball bearing 40 between the disk 31 and the upper bracket arm 26. This controlling leverat its free end is connected to a flexible member 41 which is capable of being depressed by means of a treadle which will be described later, and when depressed the belt wheel 33 makes con.- tact with the disk .31, rotates the shaft 27 and this in turnrotates the main shaft of the sewing head. lVhen the flexible member .41.

is released then thecontrolling lever is moved by means of a spring so as to lower the forked,

a which in turn bears against the belt wheel 33.

Of course, gravity also tends to move the belt wheel 33 downwardly out of engagement with the disk 31.

The shaft 27 is a hollow shaft and is provided with a suitable oil supplying means, indicated at 43. The controlling lever 37is provided with an upper arm 44, which is moved forward into contact with'the cylindrical surface of the disk 31 when said con trolling lever is swung to release the belt wheel 33. This arm 44 serves as a brake to stop the rotation of the transmitter and thus 7 stop the rotation of the sewing mechanism.

Also extending laterally from the sleeve 9 is an arm 45 in which is fixedly mounted a nut 46 adapted to engage a threaded shaft 47. As this threaded shaft is rotated the nut 46 will be caused to travel one way. or the other on the shaft for the reason that the shaft is mounted in suitable bearings which prevent any endwise movement thereof- Said shaft 47 at its upper end is mounted in a bearing carried by a laterally projecting arm48 secured t0 the upper end of the column. The shaft is provided with a reduced section 49 at its lower end which is mounted in a bracket 50 secured to the column intermediate its but any rotation imparted to the beveled gear will rotate the shaft. Extending laterally from the bracket 50 is a supporting arm 53, provided with a sleeve bearing in which is journaled a shaft 55. Rigidly secured to the outer end of the shaft is a hand wheel 56 carrying a hand crank 57. This enables the shaft 55 to be rotated by hand. the shaft 55 is a beveled gear 58 which is so positioned that the beveled gear 52 may mesh therewith when at one position on the shaft 47. There is a spring 59 between the beveled gear 52 and the bracket 50 which normally forces the gear 52 upwardly on the shaft 47 to which it is splined and to a point where the teeth of the beveled gear 52 are out of mesh with the teeth of the beveled gear 58. Directly above the beveled gear 52 is a collar 60 which is provided with a radially projecting pin 61 which enables the collar to be freely turned. This collar is provided with a cam groove 62 (see Fig. 2). Fixed to the shaft 47 is a pin 63. \Vhen the collar is in the position shown in Fig. 6, this pin rides on the outer face'of the collar and will cause the collar to force the beveled gear 52 downwardly compressing the spring 59 and bringing said beveled gear into mesh with, the beveled gear 58 on the shaft 55. When,'however, this collar 60 is turned so that the pin 63 may move into the cam groove 62 then the collar will slide endwise on the shaft and permit the spring to force the beveled gear 52 out ofmesh with the gear 58.

When the two gears above described are in mesh, then the sewing head maybe raised andlowered by the turning of the shaft 55 through the aid of the hand wheel. If, however, these gearsare out of mesh the turning of the hand wheel will notturn the shaft 47 and therefore said hand wheel maybeturned without imparting any movements up an d down to the sewing head. hen the gear 52 is out of engagement with the gear 58 the sewing head The filled bag which is to be closed is placed Fixed to a on a carriage-64. Thiscarr-iagefiat is mounted so as to be moved on supporting tracks (dB-65. The tracks 65 are in turn mounted on arms 6666, which arms are bolted to the opposite ends of a bracket 67, which bracket at the central portion thereof is provider with a sleeve 68 which is adapted to engage and freely slide vertically on the column 2. The bracket extends outwardly and downwardly from the sleeve-and carries at its outer ends the arms 66, as above noted. The arms 66 are formed of angle irons and the tracks 65-65 are formed of the usual well-known U-bars or channel bars. These tracks are spaced the proper distance apart to receive the carriage. The carriage is provided "with depending spaced brackets '69 arranged at each end thereof, and in these'spaced brackets is a supporting shaft 70, and at each end of the shaft is a roller 71 mounted on ball hearings and these rollers are in the form of flanged wheels, as clearly shown in the drawings. The flanged wheels supportingthecarriage run on the lower members of the U-ba rs forming the tracks 65-65so that theseU-bars serve as a housing for the avheels. This is quite an important feature for the reason that these filled bags are used in mills where there is a great deal of dust and dirt and the track serves as a housing for the wheels and thus in a measure protects the same from thedust and dirt. The tracks 65 65 are arranged substantially horizontally.

The bag to be stitched is placed on the 'carriage and the carriage is moved by the feed of the machine as the bag is being stitched and thus the bag is kept substantially vertical as it moves beneath the sewingfhea'd. *It will be noted from Fig. 3 that the supporting plate of the carriage is slightly :"narrow at its forward end soas notto overlap the track 65. At the extreme left-hand end of the tracks there is a Ll-shaped rod -72 which is rigidly secured to the tracks. The ends of the rods extend down through the channel bars and are threaded. Nuts 73 and '74 above and below the channel bars rigidly and adjusualbly support the same. The forward-end of the carriage passes between the vertical portion of the U-shaped rod 72 and causes the bag mounted on the carriage to engage said rods. 1 Said rod will be adjusted so as toengage the bag at a point below its center of weight and as a result the bag will tilt forward over the rod and off from the :carriage. As the bag tilts oil from the carriage, by this engagement with the rod and swingin over the rod, the bottom of the bag will give the carriage a backward kick and this will cause the carriage to :run back to the other end of the track.

As a means for holding the carriage at the right-hand end of the tracks until it is desired to move the same forward with a L- 1 .v h red bag thereon, a stop mechanism has been provided'consis'tingof a lever 7 5. Said .lever 75 isip'ivotally supported by a bracket 7 6 at the rear end of the lever and the forward end=of:the lever is capable of moving up and down in a second member 77 ri idly secured to the carriage. A spring 7 8 mounted in the member 77 bears against the under surface of the "lever 75 and normally tends to raise the same. The lever is provided ith an upwardly projecting portion 7 9 which is adapted to move up through a slot in the supporting plate of the carriage. It will readily be seen that when a filled bag is placed on the carriage it will engage this portion "79 of the leverand force it down; and, on the other hand, when the bag is removed from the carriage the spring 78 will raise "the lever.

The upper member of the U-bars is provided with a notch 80 and this notch is so positioned that when the carriage is at the extreme'right-hand cnd-of the tracks, as viewed in Fig. 7-, the lever will move up into the notch and hold the carriage in this position. Therefore, when'the bag falls off the carriage and the carriage is given a kick backward, it will irun'to the other end of the track and the stop lever will be moved up into the notch not only stopping the carriage but holding it in this position ready to receive the next filled bag and'until the filled bag is placed thereon.

The carriage is raised and lowered vertica'lly to accommodate different sizes of bags bymeains of a threaded shaft 81. This shaft 7 81 isimoun'ted in a step-bearingfBQ at the lower end thereof and is provided with a reduced portion "83 at its upper end which is mounted in the bracketSO. nected with the sleeve68 and this nut engages the threaded shatter lVhen the threaded shaft '81 i's turned the nut will travel endwise onithe shaft and thus raise or lower the-tracks supporting the carriagedepending upon in which direction the shaft is rotated.

At the upper end of the shaft 81 there is a beveled gear '85 which is adapted to mesh with the gear, 58 when it is in the position shown in Fig. 6. This gear is normally forced in a downward direction on the shaft by a spring 86. The gear 85 is splined to the shaft andris'fre'e to move endwisethereof. A collar 87 mounted on the shaft limits the downward movement of the gear 85. A pin 88 011 the shaft is adapted to Co-operate with the cam groove 89 in the collar 87. A pin 90 is fixed to the collar 87 "and serves as a means for rotating the collar. It will readily be-seen that when the collar is in the position shown in Fig.6, then the beveled gear 85 will beheld in mesh with the beveled gear 58. hen, however,the collar-87 is turned to the posit-ion shown in Fig. 2, then the beveled gear85 'is forced out OI mesh with the beveled gear 58. hen the beveled gear 85 is out ofmesh withthe beveled gear58then thehand A not 84 is rigidly concarried shaft may be turned without rotating the threaded shaft 81 and the threadedshaft 81 will support the tracks in the position to which they have been adjusted by reason of the fact without moving the carriage, and, again,

the carriage may be adjusted without moving the sewing head. When the sewing head and carriage are simultaneously adjusted they will be simultaneously movedtoward each other or from each other by reason of the fact that the shafts 17 and 81 when both in mesh with the gear 58 will be rotated in opposite directions.

/ The flexible member 41 which is connected with the controlling lever for the sewing head is connected atits lower end to a rotatable member 91. Said rotatable member is provided with two spaced grooves 92 and 93 and the outer sidewalls of the grooves are chamfered or beveled outwardly away from the grooves. The flexible member ll which is either in the form of a chain or cord is wound about the central portion of the rotatable member 91 in the groove 92 and is secured thereto. A second fiexiblemember, such as a chain or cord 94, is located in the groove 93 and is likewise Wound about the rotatable member and secured thereto This cord 94 carries a weight 95 at its lower end. The'cord 9 1 is so woundon the rotatable member as to tend to rotate said member in a direction to wind up the cord 41. This rotatable member 91 is freely mounted on a short shaft 96 and is held thereon by a threaded nut 97. This shaft 96 is in the form of a stub-shaft threaded into the bracket 50. Mounted on this stub shaft and freely turning thereon isa lever'98. Said lever 98 is connected by means of a flexible connection such as a chain or cord 99, with an arm 100. This arm 100 is rigidly secured to a shaft 101 journaled in suitable bearings by the supporting base and at its forward end said shaft 101 carries a secondarm 102 provided with a foot treadle 103,through which the shaft 101may be oscillated and thus impart an oscillation to the lever 98.' Said lever 98 on one face thereof, is provided with beveled teeth 104 which are adapted to cooperate with beveled teeth 105 formed integral wither rigidly secured to the rotatable member 91.

which has formed therein a recess 10? with one wall thereof tapered. :The lever 98 has a tapered dog 108 which is adapted to co-operate with a tapered wall in the recessi107; As viewed in Fig. 3, it will be noted that when the lever 98 is depressed this tapered dog moving out of the recess will move the lever laterally until the beveled teeth thereon 'en-- Fixed on the shaft 96 is a collar 106 gage with the beveled teeth on the rotatable member 91. This positively connects the lever with the rotatable member so that any further depressing of the lever will turn the rotatable member. When the lever is released, it is moved in an opposite direction by means of a spring 109 which also causes the beveled teeth to move out of engagement with the beveled teeth in the rotatable member 91, so that the lever is normally out of engagement with this rotatable member.

WVhen the sewing head is raised the cord 41 willturn the rotatable member, lifting the weight 95, and, therefore, the weight will alwayshold the cord 41 taut. 'If the sewing head is lowered which would tend to give slack to the cord 41, the weight will rotate the member 91 and wind up the slack and again maintain the cord41 taut so that whati ever may be the position of the sewing head this weight and rotatable member will compensate for said position. That is, it will automatically take up the cord 41 and all slack out of the same. depressed, therefore, and the lever is connected up with the rotatable part it will move said rotatable part in such direction as to further wind up the cord Hand oscillate the controlling leverwhich will start the sewing mechanism.

From the above, it will be apparent that therehas been provided a filled bag sewing When the treadle is! mechanism very light in construction and which can be very cheaply made. Said filled bag sewing mechanism also includes a carriage which may carry the weight of the bag to be'closed and which carriage can be moved by the operator to feed the bag to the sewing head. When the carriage reaches the end of its travel, the bag engages the rod and falling" over the rod kicks the carriage in the r'eversedirection so that it returns to normal position for lacing the bag thereon. After the bag has een placed, the operator depresses the treadle and starts the sewing mechanism. When the sewing is finished and the treadle is released thesewing mechanism willbe disconnected from its operating motor and the brake applied to stop the sewing mechanism.

' The machine is readily adapted for stitching bags of varying sizes. An operator can much more readily feed the mouth of the filled bag to a stitching mechanism if said iio sired range for shifting the sewing'machine. By the apparatus described above, it will readily be noted that the carriage may be raised when the head is lowered and therefore, the apparatus is capable of being adjusted for a wide range in heights of bags without excessive adjustment of the sewing head. Then,.again, it is often desirable to adjust. the carriage alone without adjusting the height of the head, so that the head may be left at a desired height for stitching and all adjustments made by raising or lowering thecarriage; There are also other condi-' tions under which it is desirable to raise or lower the head without moving the carriage up and down; as, for example, in the stitching of a bag where there is a worn place in the mouth of thebag, which makes it essential to stitch that particular bag at a lower level. It will readily be seen that all adj ustmentsmay be quickly accomplished by the above apparatus. All the operator has to do is to quickly throw the collars controlling the beveled gears and the machine may be set so as to simultaneously raise and lower the carriage and the sewing head or to raise the carriage without shifting the sewing head or to raise and lower the head without shifting the carriage. -In whatever position the sewing head maybe shifted the controlling mechanism operated by the treadle adapts itself for the new position ofthe sewing head.

It is obvious that minor changes in the details of construction and the'arrangement of the parts may be made without departing from the spirit of the invention as set, forth inthe appended claims. 1 7
