Application filed May 9, 1914. Serial No. 837,394.

To all whom it may concern:

Be it known that I, DUDLEY S. SEYMOUR, a citizen of the United States, residing at Chicago, in the county of Cook, State of ti Illinois, have invented certain new and useful Improvements in Filled-Bag-Sewing Machines, of which the following is a description, reference being had to the accompanying drawing and to the figures ofreference marked thereon.

The invention relates to new and useful improvements'in filled bag sewing machines and more particularly to means which are adapted for stitching the mouths of relain tively small bags which may be supported by the mouth thereof and fed to the stitching mechanism.

An object of the invention is to provide a supporting device for filled bags whereby to each bag may be held supported at a plurality of points and the mouth of the bag while so held presented to a stitch forming mechanism for closing the same.

A further object of the invention is to provide a device of the above character with means for simultaneously releasing the bag from all its supporting points.

A further object of the invention is to provide means for severing the connecting chain to of stitches between a stitched bag and the sewing mechanism prior to the releasing of the same from its supporting means.

These and other objects will in part be obvious and will in part be hereinafter more at fully disclosed; I

In the drawings which show by way of illustration one embodiment of the invention: I

Figure 1 is a side view of a filled bag sewto ing machine embodying my improvements, a portion of the work support being broken away to show the looper.

Fig. 2 i a view of the opposite side of the machine.

Fig. 3 is a transverse sectional view through the overhanging arm and the work supportand showing the supporting means for the bags in top plan view.

Fig. 4 is ,a sectional view on the line 44 so of Fig. 3.

Fig. 5 is a sectional view on the line 5-5 of Fig. 3. Fig. 6 is a view more or less diagrammatically showing the support for the bags, two

closed bags carried thereby with the connecting line of loops joining the bags and the positioning of the cutter relative to the said line of loops.

Fig. 7 is a detail in section, showing a part of the supporting ring and the stripping shoe for stripping the filled bag from the mug.

Fig. 8 is a detail in plan, showing the support for the'anvil and the support for the cutter.

The invention consists generally in providing a sewing machine which preferably is of the overhanging arm type arranged so that the work support is substantially vertical and the needle reciprocates in a horizontal plane. Mounted on a bracket supported by the overhanging arm is a rotating support for the filled bags. This rotating support is' provided with'a plurality of pins arranged in groups and each group of pins is adapted to support a filled bag. The support travels between the overhanging arm and the Work support. bags project above the support and are car- 'ried thereby so that one bag after another is presented to the stitching mechanism.

After the bags pass the stitching mechanism a cutter is automatically operated to sever the connecting loops between a stitched bag and the stitching mechanism. After this cutter has severed the chain of loops, a stripping device is automatically operated to simultaneously strip the bag from all its supporting points so that the bag will drop from the carrier.

Referring more in detail to the drawings, my improved filled bag sewing machine con- The mouths of the sists of a sewing machine proper which comprises a work support 1 and an overhanging arm 2. The work support is arranged in substantially a vertical position and is attached to any suitable supporting frame. The overhanging arm is also in substantially a vertical position and the needle bar 3 mounted in the overhanging arm reciprocates in substantially a horizontal plane. The needle bar carries a needle 4 with which cooperates a looper 5. The looper is oscillated back and forth by a link 6 which is connected to a needle lever extension 7 on the needle lever 8. This needle lever is con nected through the link 9 with a needle bar 3. The lever is vibrated by a link 10 which .coiiperates with an eccentric on the main shaft 12 is a bracket 15 which is clampedto the shaft by a set crew 16. A rotating support 25 is supported by said bracket 15 so that the support may freely rotate on the shaft 12. The support is formed with a gear 17 on its upper face and also a cam disk 18 having a cam groove 19 therein. Below said support is a second cam disk 20 which has a hub 21 resting on the bracket 15. This cam disk 20 is formed with a cut away portion 22. The cam disk 20, the support 7, the gear wheel 17, and the cam disk 18 are all clamped together by suitable screws 23 so that these parts turn as one on the stub shaft 12. The support 7 has radially projecting arms 24which as herein shown are five in number.

A supporting ring 25 is carried by the outer ends of these arms. This ring is divided into sections by cut away or recessed portions 26. Each section of the ring carries a plurality of supporting pins 27 which project outwardly from the ring. These pins are supportin pins for the filled bags and each group 0 pins is adapted to support a bag. The mouth of the bag is placed on these pins so that the upper edges of the mouth project above the pins as shown in Fig. 6.

The supporting ring 25 is rotated bya shaft 28 which is mounted in suitable bearings 29in a bracket 30 secured to the standard of the machine by screws 31. This shaft at its lower end carries a gear 32 shown in dotted lines in Figs. 2 and 3, which gear meshes with the gear wheel 17. The shaft 28 isv rotated by a cross shaft 33 which extends beyond the work support and is in; termittently rotated through a suitable pawl and ratchet mechanism operated by-the main shaft. The shaft 33 carries a ratchet wheel 34 which is engaged by a pawl 35. Suitable means is provlded for preventing the shaft from rotating in reverse direction which as herein shown consists of a clamping collar 36 carried by an arm 37 attached to the bed plate of the machine, see Fig. 1. As the main shaft rotates the needle is reciprocated and the supporting ring or carrier for the filled bags is moved intermittentlyso as to present each bag step by step to the stitchmg mechanism. The rotating ring or carrier 25 is so disposed that the upper edges of the filled bags which project above "the ring {grill be carried between the presser (foot 38 and the work support 1 of the machine. The work support may be provided with a groove to permit the projecting pins to pass.

The bracket arm 15 extends radially from the stub shaft to which it is secured and terminates short of the supporting ring 25. Said arm is formed with spaced

bearings

39 and 40. A rod 41 reciprocates in these bearings and carries a stripping shoe 42. This stripping shoe is curved to conform to the curvature of the supporting ring 25 and is located below the supporting pins. A spring .43 on the rod 41 bears against a collar 44 at one end and against a bearing 40 at the other end. This spring yieldingly' forces the stripping shoe toward the supporting ring 25.

A roller 45 on the inner end of the rod 41 cooperates with the cam disk 20. This cam disk has a plurality of cam projections 46, and these cam projections one after the other will engage the roller 45 and force the stripping, 'shoe outwardly away from the supporting ring 25. As soon as the cam projection passes the roller 45 the spring 43 will force the stripping shoe inward again to its normal position adjacent the supporting ring. A yielding blade 47 is fixed to the end of the stripping shoe nearest to the stripping mechanism and this blade presses against the ring continuously during the travel thereof. The purpose of this blade is to insure the mouth of the bag passing outside of the stripping shoe. The cam projections 46 are so positioned relative to the supporting ring that a bag supported on a group of pins will be brought in front of the stripping shoe before said shoe is forced outward and when the shoe is forced outward by the cam projection the bag will be simultaneously stripped from all of its supporting pins. If the bag be stripped from one pin after another, the last pin to support the bag carrying the whole weight thereof is liable to be bent or broken or to tear the bag, but if the bag is stripped simultaneously from all its pins it will drop-therefrom without injury either to the pins or to the bag.

Before the bag is stripped from the supporting pins on the carrier or supporting ring, 1t is desirable to cut the chain of stitches between the stitched bag and the sewing mechanism or the next ag being stitched. This is accomplished by a cutting mechanism consisting of a reciprocating cutter 48. This cutter is carried by a supporting rod 49 which reciprocates in

suitable bearings

50, 51 and 52 carried by a bracket 53 which is attached to or formed integral with the bracket 30. A collar 54 is secured to the rod 49 and a spring 55 bearsat one end against said collar, while the other end of the spring rests against the bearing 50.

all

Coiiparating with the cutter 4.8 is an anvil or other support 56 for the 'threads which are to be cut. The cutter 18 and the anvil 56 are so positioned relative to the carrier or supporting ring 25 that the upper edges of the mouth of the bag travel between the two parts of the cutting mechanism so that the chain of stitches to be severed are held between these cutting members. The upper edge of the supporting ring 25 is cut away or recessed, as at 2b, as above described, and the cutter for cutting the threads is adapted to pass through this recessed section of the supporting ring when performing its cutting operation. A roller 57 is carried by the outer end of the bar which supports the cutter and this roller coiiperates with the cam disk 19. Said cam disk is formed with a plurality of recesses 58. The roller normally rests on the edge of the cam disk between the recesses and when a recess is presented to the roller the spring 55 operates to move the cutter +18 to sever the connecting chain of stitches. The rod supporting the cutter 48 is provided with a projecting arm 61, see Fig. 5, which reciprocates in a slot in the bracket 53 and this arm prevents the rod t9 from turning so as to always hold the cutter blade l8 properly positioned relative to the direction of travel of the connecting chain of loops between the bags. The anvil 56 is carried by an adjustable support 56. This support is slotted, as at 60, and the screws 59 passing through the slots into the bracket 30 hold the support 56 so that it may be adjusted in a direction parallel with the line of reciprocation with the cutter 48. This permits the anvil to be adjusted so as to properly coiiperate with the cutter after the same has been ground. The anvil 56, as herein shown, is provided with a forwardly projecting guiding arm 62 which guides the mouths of the bags and the chain of stitches between the anvil and the cutter 48.

ln the operation of my device, the operator places a bag on the carrier or supporting ring 25 by impaling the. mouth of the bag on the points, so that the edges of .the mouth will project above the supporting ring or carrier. As the carrier rotates, the bag to be stitched will be presented step by step to the stitching mechanism. After passing the stitching mechanism the bag mouth passes between the members of the cutter and outside of the stripping shoe. After the bag has passed the cutting members and the chain of stitches is positioned between these members, the cutter is automatically operated to sever the chain of stitches and after the cutter has severed the chain of stitches then the stripping shoe is automatically operated to simultaneously strip the bag from all of its supporting pins,

so that the bag drops from the machine. While one bag is being stripped another is being stitched and still another is being placed on the supporting pins.

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