ABSTRACT:
A clamp for clamping a plurality of strips of compressible material together comprising, a resiliently rigid plate member; a pair of vertical bar members carried by the plate member normal thereto and disposed parallel to one another at a distance generally equal to the width of the strips to be clamped together; a horizontal bar member shorter in length than the distance and disposed in parallel, spaced relationship to the plate member; and, a pair of joining bar members connected between respective ones of the ends of the vertical bar members and the horizontal bar member, the joining bar members forming and angle of between 120.degree. and 150.degree. with the horizontal bar member; and wherein, the vertical bar members, the horizontal bar member, and the joining bar members are of a resiliently rigid and deformable material.
The clamp is used by, placing the stacked strips to be clamped together within the clamp; applying pressure towards the horizontal bar member on the points where the joining bar members meet the horizontal bar member thereby arching and pressing the horizontal bar member towards the plate member until the strips have been compressed under said horizontal bar member and the joining bar members have toggled over center from an original position at approximately 135.degree. upward to a position approximately 135.degree. downward; and, applying pressure on the points where the joining bar members meet the vertical bar members in a direction to urge the vertical bar members back towards one another and a perpendicular position relative to the plate member whereby the vertical bar members hold the horizontal bar member firmly against the compressed strips.
