    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形部件包括当螺纹穿过线轴时引导螺纹的宽凸缘，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形部件提离主轴 。
