Abstract: A sewing machine wherein the upper thread spool is held fast on its spindle within the housing provided for it while the thread is wound off the spool in a direction extending substantially in alignment with the spool axis. The cover of the housing may be shifted outwardly together with the spindle which is secured to it to allow removing and replacing the spool. A cap-shaped member fitted loosely over the spool includes a broad flange guiding the thread as it passes off the spool while means are provided to lock the cover in its closed position and to lift the cap-shaped member off the spindle before releasing the cover.
Abstract translation: 一种缝纫机，其中所述上线卷轴在其为其设置的壳体内的主轴上快速保持在其中，同时线沿着基本上与卷轴轴线相对延伸的方向卷绕在卷轴上。 壳体的盖可以与固定到其上的主轴一起向外移动以允许移除和更换卷轴。 松紧地安装在卷轴上的帽状构件包括当螺纹穿过线轴时引导螺纹的宽法兰，同时提供用于将盖锁定在其关闭位置的装置并且在释放盖之前将盖状构件提离主轴 。

Abstract: A multipurpose presser foot for sewing machines comprises a sole pivotally mounted to a flange-plate for attaching the foot to a presser bar with an alignment so that, in operation, a part of the lower surface of the sole is adjacent to completed stitching. So as to facilitate passage thereunder of raised stitching, this part is retractable from the lower plane of the sole against the action of a spring. The retractable part is connected to the rest of the sole in the manner of a deformable parallelogram by means of a set of articulated members so that the retractable part, when displaced, remains parallel to the said plane.
Abstract translation: 用于缝纫机的多功能压脚包括可枢转地安装到法兰板上的鞋底，用于将脚连接到具有对准的压杆，使得在操作中鞋底的下表面的一部分与完成的缝合相邻。 为了便于通过升起的缝合，该部分可以从鞋底的下平面伸出来抵抗弹簧的作用。 可缩回部分通过一组铰接构件以可变形平行四边形的方式连接到鞋底的其余部分，使得可移动部分在移位时保持与所述平面平行。

Abstract: A system for adjusting the tensile stress to which the upper thread of the machine is subjected by means of a spring engaging an arrangement including a spindle carrying two plates between which the thread is held against friction during its progression from its spool towards the needle. The adjustment of the spring is ensured by means of two levers connecting corresponding points of the spring respectively with the spindle of said arrangement and with the cam normally controlling the actual tensioning of the spring.
