    Abstract: This invention is a dual foot pedal control for a sewing machine consisting of a foot activated tiltable pedal assembly mounted on a base member which is attached to a stabilizing mat. The stabilizing mat is positioned between the legs of a sewing machine table, on which a sewing machine is mounted. The tiltable pedal assembly is connected by rod to a sewing machine control arm which activates the sewing machine. In addition, the sewing machine is speed controlled by the counter-clockwise pressure on the pedal assembly which is transmitted by rod to the sewing machine control arm. The pedal assembly, when foot-tilted clockwise, activates an air control valve which directs compressed air to an air cylinder which is connected to and opens the presser foot of the sewing machine. When tilted counter-clockwise the air control valve dissipates air to the air cylinder allowing the presser foot to lower and clamp the material to be sewn.

    Abstract translation: 本发明是一种用于缝纫机的双脚踏板控制装置,其由安装在连接于稳定垫上的基座构件上的脚活动的可倾斜踏板组件组成。 稳定垫位于缝纫机台的腿部之间,在其上安装有缝纫机。 可倾斜踏板组件通过杆连接到启动缝纫机的缝纫机控制臂。 此外,缝纫机由踏板组件上的逆时针压力进行速度控制,该压脚通过杆传递到缝纫机控制臂。 当踏板顺时针方向倾斜时,踏板组件启动一个空气控制阀,该空气控制阀将压缩空气引导到连接并打开缝纫机压脚的气缸。 当逆时针方向倾斜时,空气控制阀将空气排放到气缸,允许压脚下降并夹紧待缝合的材料。
