    摘要： An improved top roller-carriage for use on sewing machines having a bottom roller and on which superimposed layers of material are to be joined, the roller-carriage including an elongated torque transmitting shaft connected through intermediate mechanisms to the main drive and including means for mounting the torque shaft on the machine in such a way that it can be pivoted about both a horizontal and a vertical axis so that the roller while it is connected on one end of the torque shaft can be completely removed from its operative position adjacent the machine needle and can adjust vertically to accommodate different material thicknesses.

    摘要： A sewing machine for sewing two material layers to each other in aligned positions, comprises a top feeding mechanism engageable with a top layer for feeding it and a bottom feed mechanism engageable with a bottom layer of material for feeding it. The top and bottom feeding mechanisms are connected to a synchronizing device which regulates the relative speed between the two. A sensor or measuring means is engageable with the material being fed and is connected to the synchronizing means in order to vary the relative speed of the top and bottom feeds in accordance with the actual feed of the material layers.

    摘要： A sewing machine for stitching leather or fabric sheet is provided with means for manually or automatically steering a work sheet past the sewing head to ensure that the line of stitching follows a required path, the steering being effected by imposing a local frictional drag on the sheet at a point offset from the line of action of the mechanical feed of the machine. The platen of the machine may be provided with a pair of domed studs which protrude upwardly one on each side of the feed line enabling the operator to press the work sheet down differentially on the studs with his fingers to effect a steering of the work by frictional drag. In another arrangement a yoke plate is rigidly or tiltably mounted on the presser bar of the machine and carries a pair of downwardly-protruding domed pressure studs which when pressed down differentially provide the required steering action. One of these pressure studs may be deeper than the other to act as an edge-follower for engaging a curved edge of the work sheet, whereby automatic steering of the work sheet is possible by which the seam will be stitched parallel to but inset from the edge being followed. Instead of cooperating with an edge of the work sheet itself, the edge-follower stud may follow an edge of a template or overlay placed on the work sheet, or an edge of a change in thickness or level in the work sheet, produced for example by a surface channel or the edge of an underlay. The invention may be applied to cutting, welding, finishing and other linear work as well as to stitching.
