  • Patent number: 4219724
    Abstract: A manually operable device for pressing fabric comprising two triangular-shaped jaws, each of which has a flat surface portion. These surface portions face each other and constitute the working surfaces of the device. The two jaws are each secured to a handle. These handles are pivotally joined by a hinge so disposed that the two flat surface portions are separated from each other or are in parallel pressure engagement. The separated position of the surface portions constitutes the loading position of the device for inserting fabric between the two jaws and the other position constitutes the pressing position for pressing fabric inserted between the two jaws. Springs coacting with the handles bias the same into one or the other of the two positions.
