  • Patent number: 4093138
    Abstract: A portable apparatus for holding and dispensing a coiled strip of ribbon-like material, such as tack strip which is used in the upholstery business, includes a pair of parallel rods which are rigidly connected at first end thereof, with the length of said rods being substantially longer than the radius of a full coil of the material. The separation of the rods is only slightly greater than the width of the ribbon-like material. An arm is pivotably connected to and mounted between the pair of rods intermediate the length of said arm and relatively near one end thereof, so as to divide the arm into longer and shorter portions. The longer portion of the arm is curved inwardly to the extent that its distal end lies near the periphery of a coil of the material. Means, such as a cotter pin, holds the coil between the rods. A spring is mounted for biasing the arm toward general longitudinal alignment with the rods.
