Abstract: Work feeding mechanism and a rotatable loop taker are provided for a sewing machine in a module wherein a rock shaft connects with a feed bar through a flat spring enabling a feed dog on the feed bar to be moved by camming means in a direction perpendicular to the work feeding direction as the feed dog is moved in the work feeding direction by the action of the rock shaft. The camming means which is disposed under the feed bar is located in line with the feed dog to minimize inertia effects and guiding means associated with the feed bar maintain the feed dog level as the feed dog is moved in the work feeding direction and perpendicular to it.

Abstract: A platform for mounting a sewing machine in a cabinet is disclosed which is pivotally mounted to the cabinet thereby allowing the sewing machine to be stored within the cabinet without being removed from the platform. This platform is intended for cylinder bed or convertible bed sewing machines in that it is also capable of raising and lowering the sewing machine, between a position where the work supporting surface of the sewing machine is coplanar with the cabinet top and a position where the work supporting surface is spaced above the cabinet top, without an accompanying horizontal shifting component. This enables the cabinet to be formed with a smaller sewing machine opening minimizing any gaps between the cabinet and the sewing machine and eliminating additional inserts needed to close these gaps.
Abstract translation: 公开了一种用于将缝纫机安装在机柜中的平台，该平台可枢转地安装在机柜上，从而允许缝纫机储存在机柜内而不用从平台上移走。 该平台用于气缸床或可转换床缝纫机，其还能够在缝纫机的工作支撑面与机壳顶部共面的位置与工作位置之间升降缝纫机 支撑表面在机柜顶部上方间隔开，而没有伴随的水平移动部件。 这使得机柜可以形成一个较小的缝纫机开口，使机柜和缝纫机之间的任何间隙最小化，并消除了封闭这些间隙所需的额外插入件。

CPC classification number: D05B85/14
Abstract: A needle looper assembly for a lockstitch sewing machine wherein the upper thread is retrieved by a sewing needle extending through a work material, which sewing needle has an extensible hook portion for catching an upper thread and drawing the same down through the work material to a looptaker in the bed of the sewing machine. The needle looper assembly is supported on the end of a lever pivotally carried in the sewing machine bed to extend transversely thereof. The lever has the needle looper assembly attached to one end thereof, and may be actuated by a cam so as to drive the needle looper assembly to an elevated thread catching position or to a retracted thread releasing position. Retaining means are provided associated with the needle looper to permit an upper thread to be caught and held during passage through a work material and to be released when in a retracted position adjacent the looptaker.

Abstract: A thread handling device is disclosed in a type 301 lockstitch rotary hook loop taker sewing machine having a three-to-one hook to arm shaft ratio for controlling and metering slack needle thread prior to needle penetration to prevent the thread from wrapping around the point of the needle, which could prevent loop seizure, break the thread, or interfere with correct stitch formation. The thread is guided between two stationary members, with the controller between the members, the controller comprising an edge attached to the needle bar drive connecting link, moving with it, and only engaging the thread as the take-up and needle bar descend, providing a lengthened thread path prior to needle penetration.
