  • the cam device 24 is disconnected from the shaft 25 during the operation of the stitchforming mechanism but is adapted to be clutched to the shaft 25 and to make one revolution when the shaft 7 and the stitchforming mechanism come to rest upon the completion of the sewing operation.
  • the clutch by which the cam device 24 is clutched to the shaft 25 may be all as illustrated in the above-mentioned Patent No. 1,771,670 and it includes a clutch pin 27 which is normally held inoperative by a clutch dog 28 in the form of an arm fast on a shaft 29 journalled in the frame 1.
  • a clutch dog 28 in the form of an arm fast on a shaft 29 journalled in the frame 1.
  • the clutch device is of the one-revolution type so that it will be disengaged automatically when the cam device has made one rotation, all as described in said above-mentioned Patent No. 1,771,670.
  • the shaft 29 has fast thereto an upstanding arm 30 which is bent laterally at its upper end as shown at 31.
  • the block 18, which car ries the stop dog 19, has an arm 32 pivotally mounted thereon at 33, said arm being held against the side face of the block by a spring 58.
  • the shaft 7 has fast thereon a cam member 34 provided with a cam portion 35, said cam portion 35 being so placed that when the clutch-controlling member 10 is in clutch-disengaging position the arm 32 is situated in line with the cam 34 so that as the cam rotates the cam projection 35 will strike the lug 36 on the arm 32 and swing the latter forwardly as shown in Fig. 3.
  • This forward movement of the arm 32 it will engage the bent end 31 of the arm 30 and thus rock the shaft 29 thereby raising the clutch dog 28 and releasing the clutch pin 27.
  • This release of the clutch pin is, therefore, positively accomplished and is not dependent on any shock or jar given to the stop dog or any other part during the stopping of the machine.
  • One feature of my present invention relates to a novel means associated with the driving and stopping mechanism for maintaining the latch 37 raised while the driving clutch is engaged.
  • the latch 37 is shown as provided with a tail portion 44, the end of which is adapted to be engaged by a cam face 45 formed on an extension 46 that is secured to the block 18.
  • connection 56 is designed so that when it is moved downwardly it will first operate the lever 55 through the connections 57, 58 thereby to cause the roll 59 of said lever to raise the latch and release it from the lug 42, this release of the latch occurring before the connection 56 actuates the link 17.
  • the combination Wit stitch-forming mechanism of a driving shaft for operating the same, a stop motion device to bring the shaft to rest at the end of the seam, supplementary devices for performing a supplementary operation after the com pletion of the seam, a normally-idle cam de vice for actuating said supplementary devices and a cam on said driving shaft separate from said stop motion to render the normally-idle device operative just before the stop motion brings the shaft to rest.
  • the combination with stitch-forming mechanism, of work clamps a latch which in its operative position holds the work clamps open, said latch having a tail, a clutch by which the stitch-forming mechanism is operated, a clutchc0ntrolling member for actuating the clutch, and means associated with the clutchcontrolling member to engage the tail of the latch when the clutch is in engagement thereby to hold the latch in its inoperative position.
