Definitions

  • the stitch selector comprises a built-in set of control cams cooperating with a cam follower that, for the purpose of cam selection, is manually displaceable in the axial direction after being manually lifted off the cams.
  • the lateral deflections of the needle bar are controlled by a cam follower, and the movements of the material feeder in the base plate of the machine are conjointly controlled by another follower coacting with a second set of cams.
  • the two followers are first moved by a manual member out of engagement with the respective two cam sets, and are thereafter shifted to a new position by actuation of a second manual member.
  • a pointer connected with the second member indicates the selected stitch pattern on a stationarily mounted scale of indicia.
  • a zigzag sewing machine with an exchangeable set of cams as well as a built-in cam set.
  • This machine has a manual adjusting member in synchronous driving connection with a drum equipped with feeler' pins as well as an indicator scale representing the selectable stitch patterns.
  • the manual control member When changing the selection, the manual control member must first be displaced in axial direction and, while being thus kept displaced, must be turned about its axis.
  • the manual adjusting member for selecting a cam is journalled on a swing member and participates in the needle-bar oscillations during sewing operation in synchronism with the selected cam disc.
  • the visible sides of the exchangeable set of cams carry symbols and numbers.
  • the exchangeable set of cams is inserted in the machine, only the symbols or numbers on the side facing the seamstress can be read.
  • the proper selection is inconvenient and may involve errors. For that reason, when selecting the rear cam disc, it is sometimes necessary to first make a sewing test in order to ascertain which particular sewing pattern is produced by the particular cam disc.
  • I provide the stitch selector devices, in a zigzag sewing machine having a plurality of stitch and/or feed control cams for selective cooperation with a cam follower, with a single exteriorly accessible manual control member which, for normal operation, is movable along only one given path of motion and has a number of predetermined rest or catch positions corresponding to respectively difierent stitch selections; and I further provide this member with a lifter cam and a selector cam of mutually correlated cam contours which, as the manual member is being moved from one to the next position, first disengage the follower from the cams, then axially displace the follower relative to the cams or vice versa, and thereafter reestablish the cam-follower engagement.
  • I provide the set of stitch-control cams with a group of cams for controlling the lateral deflections of the needle bar and with another group of cams for controlling the motion of the material feeder, the two cam groups of the single set being correlated to respective two cam followers so that any selection of a lateral-deflection control cam is accompanied by a correlated selection of one of the respective feed control cams; and I cooperatively connect the above-mentioned lifter cam with the cam followers of both cam groups for simultaneously disengaging them from these groups during a given interval of displacing motion performed by the manual control member when being shifted from one to the next position of rest.
  • the single path along which the manual control member is movable for stitch selection is a rotationalmovernent about the axis of the manual member, and the set of stitch-control cams, the lifter cam and the selector cam are all mounted in coaxial relation to the rotatable manual member.
  • the set of control cams including, as the case may be, a group of deflector-control cams as well as a correlated group of feeder control cams, is exchangeable as a single unit and is removably coupled with the manual control memher which, in turn, is mounted on the machine frame structure and, when being shifted or turned between its predetermined rest positions, is coupled with the exchangeable set of cams.
  • each of the available, different sets of cams can be provided with corresponding indicating symbols so that in each case only those symbols are visible to, and need be observed by, the seamstress whose correlated cams are inserted into and active in the machine, thus securing a reliable and virtually foolproof operation of the stitch-selector machinery.
