摘要： A sewing machine provided with a set of pattern generating cams is also provided with a user-operated multi-setting pattern selector dial. When the selector dial is turned to a particular setting, to thereby cause the pattern generating cams to generate the corresponding pattern, a first mechanism automatically selects a respective feed pitch (amount of cloth feed per needle penetration), appropriate for the type of pattern selected. Accordingly, the user is not troubled to determine, by trial or error or otherwise, what feed pitch values would be clearly unsuitable for the selected pattern, and is instead automatically presented with a standard feed pitch value appropriate for the selected pattern. However, the user can also turn a second selector dial to increase the automatically selected standard feed pitch value by an amount up to 50% thereof, or alternatively to decrease the automatically selected feed pitch value by an amount up to 50% thereof, for example to take into account unusual thinness or thickness of the cloth being sewn on.
摘要翻译：设置有一组图形生成凸轮的缝纫机还设置有用户操作的多设置图案选择器拨盘。当选择器拨盘转到特定的设置时，由此使得图案产生凸轮产生相应的图案，第一机构自动选择适合于所选择的图案的类型的相应进给间距（每针穿刺的进给量）。因此，用户不会因试验或错误或其他原因确定什么饲料间距值显然不适合所选择的花纹，而是自动呈现适合所选图案的标准饲料间距值。然而，用户还可以转动第二选择器转盘，以将自动选择的标准进给间距值增加至多达50％，或者替代地将自动选择的进给间距值减少高达其50％的量考虑到正在缝制的布的异常薄度或厚度。

摘要： An opening plate which closes a lower thread bobbin is provided with a drawing of a bobbin on its surface. A bobbin drawing is exactly overlapped with the bobbin when the plate is completely closed. Also a drawing of a thread tension adjusting device in a required position and a drawing of a lower thread normal path are provided on the opening plate. The drawings indicate to a machine operator the position of lower thread holding bobbin correctly inserted in a horizontal full rotation loop taker device and the path of drawing of the lower thread therefrom so as to enable the operator to insert the lower thread holding bobbin in the horizontal full rotation loop taker device correctly in place, and pass the lower thread wound on the bobbin through the thread tension adjusting device correctly.
摘要翻译：关闭下线轴筒的开口板在其表面上设置有筒管的图。当板完全关闭时，筒管图与筒管完全重叠。另外，在打开板上设置有所需位置的线张力调节装置和下线法线的图形。附图向机器操作者指示正确地插入水平全旋转接收器装置中的底线保持筒的位置以及底线的拉线路径，以使操作者能够将下线保持筒管插入水平全旋转接收器装置正确就位，并通过线张力调节装置正确地通过缠绕在线轴上的下线。
