Abstract: This disclosure relates to an improvement to spring type flexible chutes provided for delivering disk-like objects from a supply source to an attaching machine. The improvement includes a resilient, elongated spacer which may be inserted into the guideway of the chute for changing the space constraints thereof to maintain a uniform planar orientation of the disk-like objects between the supply source and the machine whereby allowing one chute to be used for multiple purposes.

Abstract: A button clamp assembly having an unalterable pivot and provided with interchangeable turret assemblies which cooperate with other universal assemblies in controlling the planar displacement of the articles being delivered to the machine's sewing station. The interchangeable assemblies are mounted in a manner permitting a consistent clamping relationship to be maintained between the turret assembly and the machine's work support regardless of the article's thickness or ligne/diameter.

Abstract: A thread separating finger used in combination with a knife assembly adapted for cutting thread utilized in a sewing machine with said assembly having first and second levers, each lever having first and second end portions and a medial portion therebetween, said first end portion of said second lever defining a first cutting blade portion, first means at said second end portion of said second lever for mounting said second lever for pivotal movement, a link having first and second end portions and a medial portion therebetween, said first end portion of said link defining a second cutting blade portion cooperative with said first cutting blade portion for cutting a thread therebetween upon relative pivoting motion between said link and said second lever, second means pivotally connecting together said medial portions of said link and second lever, and third means pivotally connecting together the first end portion of said first lever and the second end portion of said link whereby motion imparted to the seco

Abstract: An automatic button feeder is disclosed including a lifting mechanism arranged for facilitating disengagement of the orientating mechanism associated therewith. The lifting mechanism includes a slideably supported member means which is connected to the orientating mechanism of the button feeder by means of a curved leaf spring. An actuator, which is responsive to movement of the button clamp lifting mechanism, moves the slideable member, and thus the orientating mechanism connected thereto, whereby facilitating disengagement of the latter in timed relation to the sewing cycle.
