  • a machine frame 20 comprises a cylindrical bed 22 securely mounted on a base 21, and a standard 23 rising above said bed 22 so as to support a bracket arm 24 overhanging the bed 22.
  • the later described loop taker In the interior of the end portion of the cylindrical bed 22 is disposed the later described loop taker.
  • a cap member 25 To the cylindrical bed 22 is detachably fitted a cap member 25 to allow the bobbin case to be inserted into and taken out of said bed 22.
  • a main drive shaft 26 journaled lengthwise in the bracket arm 24 drives all the moving parts of the sewing machine and may be actuated by an electric motor (not shown) through a foot treadle or the like (not shown).
  • a counterbalanced crank 27 on the main shaft 26 is operatively connected through a connecting rod 28 to a needle bar 29 endwise slidable in a support 30 pivoted at 31 on the bracket arm 24 and holding at its bottom a thread-carrying eyed needle 32.
  • a needle thread takeup lever 33 is also actuated by said crank 27 and constrained by an anchor link 34 so as to tightly stretch and slacken the needle thread alternately in timed relationship with the endwise reciprocation of the needle 32.
  • the passage of the needle thread extends from its source (not shown) to a thread tension device 35 through an eyelet 36 in the takeup lever 33 and then through appropriate guides such as a thread guide 37 on the needle bar 29 and finally to the needle eye.
  • This arrangement for controlling the passage of the needle thread is typical of that which is requited for the formation of lock stitches.
  • Numeral 38 in FIG. 4 denotes a loop taker shaft mounted on the frame 20 rotatable around a horizontal axis parallel with the direction in which there is fed a work fabric 39.
  • a loop taker 41 with a loop seizing beak 40.
  • the loop taker shaft 38 is connected to a lower shaft 44 through a set of gears 42 and 43 (FIG. 5), said lower shaft 44 interlocking with the main drive shaft 26 by means of a timing belt 45 (FIG. 2).
  • the loop taker 41 is designed to rotate twice each time the needle makes one reciprocation by means of the aforementioned arrangement.
  • the needle and loop taker 41 are actuated in such timed relationship that while the needle is brought downward, the loop released from the needle eye is seized by the loop taker 41 and while the needle is lifted, the loop seized by the loop taker is released therefrom.
  • a bobbin case retainer 47 adapted to receive an ordinary bobbin case 46.
  • Numeral 49 of FIG. 5 represents a restraining member, the base end of which is fixed to the frame by screws 50.
  • a tongue 53 freely engaging the recess 48 to define an opening 52 therewith so as to permit the passage of a loop 51 released from the loop taker 41 lifted by the thread takeup mechanism, thus preventing the bobbin case retainer 47 from rotating with the loop taker 41.
  • the linear work feeding mechanism is timed to the recipro cation of the needle so that while the needle 32 is raised above a work fabric on the throat plate, the feed dog 54 is lifted to be advanced and while the needle descends, the feed dog 54 is brought beneath the throat plate back to its original position.
  • Numeral 62 of FIG. 1 denotes a knob for causing the feed dog 54 to perform a drop feed.
  • Numeral 63 is a manually operable knob for controlling the advance and retraction of the feed dog 54
  • numeral 64 represents a manually operable knob for controlling the amplitude of the zigzag motion of the needle.
  • Numeral 65 of FIG. 5 shows a loop retaining member having its intermediate portion rotatably mounted on the restraining member by a stepped screw 66.
  • One free end of the loop retaining member 65 has a retaining section 67 for temporarily holding the released loop 51 pulled up through the opening 52 by the thread takeup mechanism.
  • one side 67a of the retaining section 67 is so formed as not to project from one lateral portion 53a of the tongue 53 of the restraining member 49 disposed on that side of the bobbin case retainer 47 to which the recess 48 is pressed as the result of the rotation of the loop taker 41.
  • the loop 51 released from the loop taker 41 is lifted without being detained in the space between the aforesaid lateral portion 53a of the tongue 53 and the recess 52, always enabling good uniform chain stitches to be realized without any difficulties, for example, the slackening or resultant double'formation of chain stitches.
  • Numeral 68 is a spring stretched between the other end of the loop retaining member 65 and the lug 70 of the fitting member 69.
  • the spring 68 causes the loop retaining member 65 to rotate anticlockwise as shown in FIG. 5, thereby normally keeping the retaining section 67 of the loop retaining member 65 at a position above the opening 52 to hold the loop released from the loop taker 41.
  • Numeral 71 in FIG. 14 is a groove formed at the upper part of the bobbin case retainer 47 across the recess 48 so as to extend toward both sides of the recess 48 in a sufficiently large size to receive the retaining section 67 of the loop retaining member 65.
  • the other free end of the loop retaining member 65 is bent, as shown in FIG. 3, so as to surround one end of the restraining member 49 to form a bent section 74, which contacts the underside of the restraining member 49 to prevent the loop retaining member 65 from being unnecessarily lifted. Accordingly, the retaining section 67 of the loop retaining member 65 is prevented from lifting the bobbin case retainer 47 by means of the projecting wall 72, thereby applying an excess load to the race section between the bobbin case retainer 47 and the loop taker 41. This avoids the obstructed rotation of the loop taker 41 and the occurrence of noises and wear, enabling the loop to be reliably held by the loop retaining member and chain stitches to be formed constantly.
  • numeral 75 is an actuating plate pivoted to the restraining member 49 swingably about a pin 76 fixed to the base end of said actuating plate 75.
  • the rising section 75a of the actuating plate is contacted by the other end of the loop retaining member 65 by the action of the spring 68, normally urging the free end 75b of the actuating plate 65 upward so as to face the underside of the feed dog 54.
  • the actuating plate 75 is swing downward as the result of the descent of the feed dog 54 to rotate the loop retaining member 65 against the action of the spring 68, thereby allowing the loop 51 held by the loop retaining member 65 to be released therefrom by means of the thread takeup mechanism after the needle has passed through said loop 51.
  • a pivoting member 77 for rotatably supporting the pin 76 of the actuating plate 75 between said pivoting member 77 and the backside of the restraining member 49 is fixed, as shown in FIGS. 7, 9 and 10, to the backside of the restraining member 49 by a pair of screws 79 passing through long holes 78 perforated in the fitting member 69 and restraining member 49 in a direction perpendicular to the position in which the pin 76 is set.
  • numeral 80 is a first throat plate detachably supported by a stepped portion 81 formed on the peripheral edge of the opening perforated in the cylindrical bed 22.
  • the first throat plate 80 has a long needle aperture 82 adapted for zigzag lock stitching which extends in a direction perpendicular to that in which there if fed a work fabric, and also narrow slots 33 to allow the feed dog 54 to pass therethrough.
  • an elastic plate 85 is fitted to the underside of one end of the first throat plate 80 to prevent said throat plate 80 from being lifted by engaging the underside of the peripheral edge of the opening of the cylindrical bed 22.
  • the underside of the other end of the first throat plate 80 is fitted by screws 88 and 89 with an elastic plate 87 elastically engaging a projection 86 on the peripheral edge of the opening of the cylindrical bed 22.
  • One of the screws indicated by 89 engages, as shown in FIG. 15, the actuating plate 75 when the first throat plate 80 is fitted to the frame so as to cause the actuating plate 75 to rotate up to the point (indicated by a solid line) where it is not operated as the result of the descent of the feed dog 54.
  • the screw 89 constitutes a sort of stop projection for arresting the loop retaining member at a point where it can not hold the loop 51 released from the loop taker 41.
  • the lock stitch forming mechanism is brought to an operative state.
  • numeral 90 denotes a second throat plate detachably fitted to the frame in place of the first throat plate 80.
  • the second throat plate has a long needle aperture 91 extending in the direction in which there is fed a work fabric.
  • the aforesaid position of the needle aperture-91 prevents the chain stitched thread to be insufficiently tightened due to the resistance to which it is subjected while passing through the needle aperture 91.
  • Numeral 92 is a depression formed in continuation of the needle aperture 91 to improve tightening of a chain stitched thread.
  • the second throat plate 90 is not provided with a stop projection corresponding to the screw 89 of the first throat plate 80. Accordingly, when the second throat plate 90 is fitted to the frame, there is reestablished an operative relation between the feed dog 54 and actuating plate 75 to permit the operation of the loop retaining member 65 so as to hold the loop released from the loop taker 41.
  • a manually operable lever 94 for disengaging the throat plate by means of a stepped screw 95 (FIG. 6).
  • One end 96 of the lever 94 extends so as to face the underside of that part of the throat plate where the engaging elastic plate 87 is positioned, and the other end of the lever 94 constitutes an operating knob 97.
  • Numeral 98 represents a spring stretched across the throat plate disengaging lever 94 and restraining member 49. The spring 98 causes the lever 94 to rotate anticlockwise as shown in FIG. 6.
  • the restraining member 49 is fitted with all the loop retaining member 65, actuating plate 75 and throat plate disengaging lever 94. Since all these members can be arranged into a single unit, there is obtained great advantage in assembling and manufacturing a sewing machine.
  • FIGS. 3 to 6 represent the state where the loop 51 released from the loop seizing beak 40 of the loop taker 41 is lifted by the thread takeup mechanism and, after passing between the tongue 53 and recess 48, is held by the retaining section 67 of the loop retaining member 65. At this time, the feed dog 54 is in a rising position and disengaged from the actuating plate 75. It will be apparent, however, that the second throat plate 90 for chain stitching is not provided with a screw 89 like the first throat plate 80, so that when the feed dog 54 descends, the actuating plate 75 is brought to an operative state.
  • the cap member 25 of the cylindrical bed is opened, and the knob 97 on the manually operable throat plate disengaging lever 94 is depressed with the finger to rotate the lever 94 against the action of the spring 98. Then the engaging elastic plate 87 of the second throat plate 90 is released from the projection 86, causing said plate 90 to be forcibly pushed outward. All that is required, therefore, is to remove the second throat plate 90 and instead insert the previously provided first throat plate for normal lock stitching.
  • the first throat plate 80 When the first throat plate 80 is inserted, it is first guided to the stepped part 81 of the cylindrical bed 22 and the elastic plate 85 is pressed in place so as to engage the underside of the peripheral edge of the opening for said throat plate. When that part of the first throat plate 80 where the engaging elastic plate 87 is positioned is depressed, said elastic plate 87 engages the projection 86, causing the first throat plate 80 to be set in place as shown in FIG. 15. At this time the screw 89 of the first throat plate 80 engages the actuating plate 75 to swing it from the position indicated by the two-dot-dash line to that of the solid line, so that the actuating plate 7 5 ceases to be operated despite the movement of the feed dog 54.
  • the loop retaining member 65 is operated in the same manner as in chain stitching and the retaining section 67 is brought to rest, as shown in FIG. 16, independently of the loop passing through the opening between the tongue 53 and recess 48. Accordingly, the normal lock stitching can be commenced again by feeding the lower thread into the bobbin case 46.
  • the actuating plate 75 swings downward to arrest the loop retaining member. Therefore, when it is desired to perform embroidering with the normal lock stitches by lowering the feed dog 54, there is no need to replace the second throat plate 90 with the first throat plate 80, but it is sufficient to operate only the knob 62.
  • FIG. 19 shows the part of FIG. 14 modified according to another embodiment of the invention.
  • the embodiment of FIG. 19 eliminates the necessity of forming said projecting wall 72 above the recess 48, so that when this embodiment is used for the original lock stitching, the loop released from the loop taker 41 and lifted by the takeup mechanism passes through the recess 43 exactly in the same manner as in the prior art lock stitch sewing machine, thus exerting no hannful effect on such stitching.
  • the present invention provides a very advantageous chain stitch forming device for the general user of a sewing machine, thus widely broadening the application of an original lock stitch sewing machine.
  • a chain stitch forming device for a lock stitch sewing machine including a frame having a work support perforated with a needle aperture,
  • a loop taker so mounted on the frame as to rotate about an axis
  • a bobbin case retainer supported in the loop taker and adapted to accommodate an ordinary bobbin case therein
