Abstract: 192,904. Fairweather, W., (Singer Manufacturing Co.). Jan. 26, 1922. Labed-attaching machines.-A machine for sewing on labels is provided with means for severing a label from a strip, feeding it from severing position to stitching position, and means for folding the ends before stitching. In the application of the device to a machine of known general type, a supporting bar 15 is moved lengthwise and laterally to stitch round a label by known connections with cam grooves in a feed-wheel 17 and carries an extension 21, 22 in which is a label-receiving cavity c, Fig. 5. The label is retained in the cavity by light springs 30 and adjacent thereto are folding- scrolls 32. The label-supplying tape t passes between spring blades 33, 34 secured to an arm 35 projecting from a block 36 sliding on a fixed guide rod 38, Fig. 13, and capable of being looked by a latch-bar 42 notched to engage a stud 43. A feed-slide 45 aligned with the spring blades 33, 34 and moving in a slot in the bed 1 is connected by a link 46 to a lever 47 pivoted on the bed and connected by a link 49 to the bar 15. A three-armed lever 52 is pivotally mounted in a lug 50 on the slide 45, one arbor 53 having pivoted thereto a label grippe 55 with thin toes 56. Another arm 58 carries a knife 59 and piercing-pin 61. The third arm 62 extends downwardly and is engaged by the hooked end 63 of a rod 64 secured at its other end in a lug 66 projecting from the bar 15 by the lengthwise motion of which the three-armed lever is operated. A ledger blade 69 having a hole 75 for the pin 61 coacts with the knife and is slidably mounted on the slide 45 under the control of a spring 71 acting on a stud 73. A cover plate 76 overlies the ledger blade, space being left for the springs 33, 34. Grooves 78 in the feed-slide receive the jaws of the gripper. To control the label after release by the gripper foot, a retainer is provided comprising a light spring 83 mounted on a forked arm 85 pivoted to the slide 45 and having jaws 85<1>, 85<11>. The jaw 85<1> is engaged by a pin 86 on the arm 15 when a new label is being fed, thus moving the spring 83 away from the gripper foot. When the feed-slide is advanced the pin 86 engages the jaw 85" and moves the spring 83 between the toes of the foot and over the label. The label is moved from the advanced feed-slide to the cavity c by a pusher 88 having toes 89 with serrated edges 90 and label-engaging lugs 91. Arms 92 of the pusher embrace the bar 15 and are secured to bars 95 connected by a cross member 96 carrying a pivotally-mounted post 98 slotted to receive a pin 100 carried by an arm 101 of a three-armed lever pivoted at 102 to a fixed post 103 and actuated by a treadle-chain 105. The bar 15 is recessed at 106 to provide a support for the flange 93 of the pusher which supports the toes 89 above the label. As the pusher is advanced the flange 93 rides down a slope 107 and the serrations 90 and lugs 91 engage the label which is thrust by the pusher beneath the springs 30 and folded by the scrolls 32 at the points where it has been creased by the gripper foot. A presserfoot 108 having flanges which enter the label cavity is depressed to engage the label by a spring 114 mounted in an arm 113. The foot is lifted by a bar 116 attached to a lifting-rod 117 raised by the actuation of the three-armed lever, the arm 128 of which is connected by a link 126 to the arm 123 of a lever 120 engaging the rod 117. To prevent the manipulation of the presser-foot while the machine is running a spring-controlled locking-rod 139 is moved by a lug 138 on the stop motion lever 12 into the path of a sector 145 on the three-armed lever. A work gauge for positioning the labels on the work consists of a rod 1290, bent as shown in Fig. 2, graduated and provided with an indicator 134. In order to allow repetition of the stitching of a label, the lever 42 is engaged with a stud on the feed-slide so that when the machine is operated the blades 33, 34 move with the feed-slide and the feeding of the tape ceases.
