ABSTRACT:
An improved clamp is disclosed in which a carrier plate is mounted slidably within a housing and is moved in one embodiment in a linear direction by means of an actuator. First and second arms are mounted in the housing and in angularly oriented guide slots within the carrier plate whereby, when the actuator moves the carrier plate, the arms move so that jaws at the ends of the arms converge at a clamping position. A pin in each arm is engaged in its own slot in the housing to insure that the jaws move along a predetermined path. In one embodiment of the invention only one of the arms is movable and the other arm is fixed. In a second, self-centering embodiment of the invention both arms move towards each other and equal and opposite bending stresses are induced in the arms which bend the arms within the elastic limit of the metal.
The aforementioned Abstract is neither intended to define the invention of the application which, of course, is measured by the claims, nor is it intended to be limiting as to the scope of the invention in any way.
