An object of the invention is to provide a filled bag sewing machine of the above type wherein the stitching mechanism and the bag to be stitched are moved relative to each other so as to form a straight line of stitchinc; for closing the mouth of .the bag, and wherein the moving means is returned to its initial position by gravity.

A further object of the invention is to provide a machine of the above type wherein the sewing head is capable of being raised and lowered for bags of different heights, and wherein the stitching mechanism is con nccted to and disconnected from the operat ing mechanism by a treadle controlled means so arranged as to permit the adjustment of the sewing head up or down without disturbing said treadle controlled mechanism, and wherein said treadle controlled mechanism includes an adjusting means for regulating the action of the treadle.

Av further object of the invention is to provide a machine of the above type wherein the driving mechanism for the sewing head includes a driving pulley mounted on the frame of the machine and a driving belt running over idlers disposed so that the sewing head may be raised and lowered without requiring any adjustments of the idlers.

Another object of the invention is to provide a carrier for the bag being stitched, and tracks on which the carrier is adapted to move, which tracks are so mounted as to be tilted after the bag; stitched and is removed from the carrier, so as to permit the carrier to return by gravity to its initial hurtling, position.

Another object of the invention is to provide a m chine of-the above type wherein the tracks are tilted by means of springs and wherein the tracks may be lowered to horizontal posi ion or even inclined downwardly. if desired, in the direction of feed of the bag, by the treadle connection.

Still another object of the invention is to provide machine of the above type wherein means is provided for raising and lowers ing the tracks bodily, and wherein said treadle connections are so arranged as to permit the raising and lowering of the tracks withoutdisturbing in any way the means for depressing the tracks against the action of the lifting springs.

These and other objects will in part be obvious and will in part be hereinafter more fully disclosed.

Genera-Z structure.

Our improved filled bag sewing machine includes a supporting base 1 which is preferably mounted so that it may be readily rolled about the mill, and means is provided for fining the base in any desired shifted position. Rising from this base is a central column 2 adjacent the upper end of which is mounted a sleeve 3 adapted to carry the sewing); head 4. The sleeve is adjustable up and down on the column and the sewing head is adjustable toward and from the column so as to vary the overhanging position of the sewing head. Also mounted on the column is another sleeve 5 which carries a support 6 on which is mounted tracks 7 for a carrier 8 for the bag being sewed. T he carrier is mounted so as to readily travel back and forth on the tracks. These tracks -are pivoted and capable of being swung to a treadle connection and may thus be brought down to a level position or a downwardly inclined position to facilitate the travel of the carrier during the stitching of the bag. The support for the tracks is also adjustable vertically, and the treadle con nections are so arranged as not to be dis turbed when the tracks are raised or lowered. The sewing head is controlled by a suitable clutch which is operated by treadle connections, and again these treadle connections are so arranged as not to be disturbed when the head is raised and lowered. The stitching mechanism is preferably driven from a driving pulley mounted on the base, and by means of a belt and idlers, which are so arranged as to permit the raising and lowerin of the head without in any way requiring adjustment of the idlers. Means is also pro vided for adjusting the idlers so as to take up the slack in the driving belt.

Sewing head, and means for raising and Z010- ering the same.

The sewing head 4: is of the usual type and includes a cylindrical support 9, an overhanging arm 10, and a needle operating lever 11, which reciprocates a needle bar 12 carrying a needle, which moves back and forth in a horizontal line. Within the cylindrical work support 9 is a feeding mechanism, the feed dog being indicated at 13. These parts are of the usual construction and it is not thoughtnecessary to go any further into a detail description of the same. The sleeve '3 which carries the sewing head is provided with a forwardly projecting bracket 14. The sewing head is mounted on four pins 15 which are secured to the sewing head by means of screws 15. These pins slide in the bracket 14 and set screws l5 are used for securing the pins in fixed position in the bracket. In order to aid in the adjusting of the head and setting it in proper position, there is a threaded stud 16 carri d by the head which passes through the bracket 1%. Nuts 17 and 18 are threaded on this stud and operate to aid in the adjustment of the head and the securing of the head in adjusted position. By releasing these nuts and the set screws, the head may be moved in or out from the bracket. The sewing head is provided with a belt wheel 19. Mounted on the bracket 14 is a transmitter for transmitting power to the sewing head. Said transmit .11 includes a belt wheel 20 mounted on a vertical shaft carried by suitable bearings in the bracket 14. On this shaftis a friction clutch 21 and a brake wheel 22. The clutch is moved into engagement with its cooperating parts by means of a lever 23which is pivoted at 24 and is provided with an arm 25 which shifts the friction clutch endwise of the vertical shaft and brings the parts into driving connection. This happens when the outer end of the lever is pulled downmirdly. Vi hen the lever is released and raised by spring 25, a brake shoe 26 moves into engagement with the brake wheel on the transmitter and stops the stitching mechanism. The friction clutch member is driven by a belt. A belt 27 connects the belt wheels 19 and 20.

011 me supporting base of the machine there is a belt wheel mounted on a shaft 28, which shaft is driven by a belt wheel. 28 and a belt 30 leading from any suitable source of power. A belt 31 runs about the belt wheel on the shaft 28. One strand of this belt 31 runs over an idler 32 which is fixed to a bracket arm. 33 carried by the column 2. After passing over the idler 32, this strand. of the belt passes over an idler 2n carried by the bearing mounted on a depending arm 35 which is pivoted at 36 to the bracket 4 carrying the transmitter. Mounted on this same depending arm is an idler 37. The other strand of the belt 3], runs over this idler 37, andthe two strands of the belt then run horizontally and over the belt wheel on, the shaft carrying the clutch member 21. It will readily be seen that the sleeve carrying the sewing head can be moved up and down without in any way disturbing the driving connections. As the idler 3 moves upwardly, it will give up slack to the belt. Fit the same time, the idler 37 is moving upwardly and will take up this slack so that the sewing head can be readily move d up and down, and as noted, the driving connections will not be disturbed. The depending arm is adjustably connected to a rod 38 and this permits the idlers 34 and 37 to be adjusted toward and from the pulley on the transmitter and thus take up any slack in the driving belt.

The sleeve 3 carrying the sewing head slides freely up and down on the column 2. There is a vertical shaft 39 mounted in a hearing at the lower end of the column and also in a hearing at the upper end of the column. The upper portion of this shaft is smooth and passes through. a small lug 40 carried by the sleeve 3. This lug slides freely on the shaft and the purpose of the shaft and lug is to prevent the sleeve from turning on the column. "his shaft has other functions which will be described later. Mounted at the upper end of the column is a cross shaft il, which carries a sprocket wheel 42 and also a large hand wheel 43. A sprocket chain ll is secured at one end to a hook 45 threaded into the bracketit, which forms a partof the sleeve 3. The other end of this sprocket chain connected to acounter-balancing weight 46 located in the column. The sprocket chain has positive connection with the sprocket wheel, and when the sprocket wheel is turned throu'gl'i the hand wheel then the chain will be moved so as to either raise or lower the be provided with a suitable handle 49 for turning the same.

Transmitter control.

Mounted on the base of the machine is a treadle 50. This treadle 50 extends from front to rear of the machine and is mounted to rot-ate in suitable bearings. An arm 51 extends laterally from the treadle is adapted for the foot of the operator, so that the treadle shaft can be rotated through this foot treadle. Adjacent the rear end of the shaft 50 is a laterally projecting arm 52. A flexible connection 53 extends from the end of the arm upwardly and over an idler 54 on the end of the transmitter lever 23. Said flexible connection extends thence over another idler 55 which is mounted on the bracket 14. This flexible connection then extends on upwardly where itis connected to a turn buckle 56 and the turn buckle is in turn connected to a bracket- 56 at the upper end of the machine. It will readily be seen that when the treadle is depressed, the idler 5& will be moved downwardly, thus swinging the transmitter lever, and when released, the spring controlling the transmitter will of course, raise this idler. lVhen the sleeve carrying the sewing head is moved up and down, both idlers 54 and 55 will move therewith, and as one gives up slack in this liexible connection 58, the other will take it up, so that the sleeve is capable of up and down movements without disturbing in any way the treadle connection to the transmitter. hen itis desired to vary the action of the treadle connection on the transmitter, then the turn buckle 56 is either taken up or let out, and this shortens the flexible connection and thus varies the released position of the transmitter lever.

Track supporting mechanism.

the front prov ded with athreaded lug 58 which en- 'bracket mounted on the column 2.

gages a threaded portion 59 of the vertical shaft 39. This vertical shaft is rotated by means of a hand wheel 60 mounted on a shaft 6O which is carried by a suitable The shaft carries a bevel gear 61 which meshes with a bevel gear 62 secured to this vertical shaft 39. The rotating of the hand wheel 60 will rotate the vertical shaft, and this will raise and lower the sleeve carryingthe supporting structure for the tracks. The tracks comprise two parallel connected U shaped members 63. These members are connected by suitable rods 83, which rods are provided with rollers 65 on which the carrier is supported and travels. e have referred to these members as tracks for the carrier, using this term in the broad sense, and meaning a meanson which the carrier travels back and forth, and not necessarily members on which wheels travel, although it obvious that a carrier may be mounted on wheels if so desired. The carrier is prevented from lateral movementon the tracks by means of rollers 66 carried by vertical stud members on the carrier, and adapted to engage guide plates 67, 67, respectively, at opposite sides of the tracks. This carrier shown consists of upper and lower members, one above and the other below the guide plates. The particular construction of the carrier and the tracks, as a matter of fact, form no part of the present invention, but are shown, described and claimed in our copending application, Serial No. 597,615, filed October 28, 1922.

From the above it will be noted that the carrier really moves back and forth on the rollers 65, and these rollers constitute the supporting; means for the carrier. The carrier has an upturned part 66 a its rear end. The bag is placed on the carrier and .I-l'lCll the carrier moved forward as the sewing are-coeds, and thus it is that the bag is con veyed past the needle during the stitching of the bag.

Mechanism for zfiZt ng tracks.

The tracks are pivoted at 67 to one of the supporting arms 57 and extend across the machine above the other supporting arm 57. Said right-hand supi iorting arm 57 as viewed in Fig. 2, is formed with an angle plate (38 which carries the pivot for the tracks. The other, or left-hand Supporting arm is pro vided with an angle plate 69. There is a standard 7 O at each side of he track threaded into this angle plate69. These standards eX- tend through perforated lugrs 71 carried by the lJ-shaped members 63. spring 72 surrounding each standard. sprii at the upper end bears agaii "t the lug 71, and at its lower end be: against a washer 72 carried by a nut 73 which may be adjusted up and down on the standard 70.

This

There is a coiled llll) It will thus be seen that the left-hand end of the track may be depressed and at such time, the springs will be compressed while the standards 7 0 will pass upwardly through the openings in the lug 71. /Vhen the tracks are free from weight, the carrier will be posi- 'tioned as shown in Fig. 2, with the left-hand end raised through the springs referred to.

lVe have provided means for lowering this end of the track which is controlled from the treadle 51. On the shaft 50 adjacent the treadle is a projecting arm 74:. A flexible member 7 5 connected to the arm 74 runs over an idler 76 carried by a cross bar 77 which is attached to the U-shaped members forming the track for the carrier. This flexible member thence runs over an idler 78 carried by one of the supporting arms 57. Said flexible member runs up through the arm or support 57 freely and it is attached to a bracket arm 79 carried by a fixed collar on the column 2. It will readily be seen that when the treadle is depressed, the idler 76 will be lowered and this will draw the le t-hand end of the tracks downwardly. The tracks may be lowered until the adjustable stops SO engage the llshaped members 63. These adjustable stops are carried by angle brackets 81 mounted on one of the supports 57, and the stops are held in adjusted position by means of lock nuts 82. These stops can be readily raised or lowered, and this will determine the lower position of the tracks. The stops may be set so that when the tracks are lowered, they will be level, or they may be set below this position, so that the left-hand end of the tracks when lowered is such that the tracks incline downwardly from right to left or in the direction of travel of the carrier during the sewing. This is for the purpose of aiding in the free movement of the carrier when-loaded with a heavy bag and during sewing, so that the sewing machine feed will, without any difficulty, move the bag while it is being stitched. The sewing machine feed can also move the bag when the carrier moves in a horizontal plane as the carrier is mounted to move on rollers and is very light. As soon as the bag has been completely stitched and the operator lifts the same from the tracks, he releases his foot from the treadle, and the springs raise the left-hand end of the tracks, so that the carrier will move back to its initial position for loading. hen the carrier is in initial position for loading, the central part thereof is preferably substan tially over the pivotal point 67 for the tracks, and this enables the bag to be tamped and the contents properly settled therein before feeding along to the stitching mechanism.

While the transmitter lever and the tracks are both arranged by the same treadle, the flexible connections can be so proportioned that the tracks will be lowered first before the transmitter is operated to start the stitchmg mechanism.

Stops for the carrier.

The ti -shaped members (53 forming the tracks, are connected at their outer ends by rods 83. These rods project rearwardly beyond the Ushaped members (33 at the roar of the machine and carry a rod S l which extends the full length of the tracks. This rod 84- is provided with an adjustable bracket 85 in which is mounted a buffer 86. It also carries a bracket 87 in which is mounted a buller 88. There is a suitable lug 89 on the carrier which is adapted to engage the buffer 88 when'the carrier moves forward to limit the travel of the carrier and prevent it from running off the tracks and the same lug is adapted to engage the buffer 86 when the carrier is moved to the right, and stops the carrier at its initial loading position.

These steps are made adjustable for the reason that various sized bags vary in width of mouth, and it is desired to have the car rier only travel a sullicient distance to convey the bag to the stitching mechanism and then return. This saves time and considerable wear and tear on the machine.

Operation.

it is thought that the operation of our device will beclear from the description given above in detail. The bags to be closed are fi led and are placed by the operator on the carrier which at the time, is at the righthand end of its travel, as viewed from the front of the machine. The mouth of the bag is then raised so as to be directed into the feed of the sewing machine, and the operator by placing his foot on the treadle, depresses the tracks preparatory to the forward movement of the carrier, and this shifts the transmitter to start the stitching mechanism. The bag is fed through the machine by the feed of the sewing machine and the carrier travels along therewith. After the bag has passed through and the stitching is completed, th operator releases the treadle which stops the stitching mechanism, and when the bag is lifted from the carrier. the tracks will be raised by the spring. and the carrier will automatically return to its initial loading position by gravity.

If a different sized bag is to be stitched and the variation is only slight compared with the one p'eviously stitched, then the sewing head may be quickly raised or lowerod by the hand wheel 4-3 and this may be done without in any way disturbing either the driving connections for the sewing head or the treadle connection for the transmitter. If a greater range of adjustment is desired, this can be done 'by turning the hand wheel 60 which will turn the vertical shaft 39 and thus raise and lower the support for the tracks. This may be done also without in any way disturbing the treadle connections for tilting the tracks. In fact, both the sewing head and the tracks may be moved toward each other or away from each other if desired.

From the above it will be noted that we have provided a machine which is very simple in construction, capable of very wide adjustments, and which requires a minimum amount of power for operating; also a machine wherein the bags may be quickly stitched and the machine again brought into position for the next It is clearly a one-man machine wherein all the parts to be actuated by the operator, are readily accessible to him.

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 in the appended claims.

Having thus described the invention, what we claim as new and desire to secure by Letters-Patent, is
