Abstract

Abstract An apparatus for parting adhering bodies in which two jaws, operative to frictionally engage each one body, are connected to a common holder through arms diverging towards the jaws and, hence, effective to spread them apart by a sort of toggle-joint action, when the holder is pressed towards the bodies. A counterholder is provided to engage the opposite side of the bodies.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 186 words
An apparatus for forcing apart a pair of bodies which adhere to each other with substantially planar surfaces and both of which have two opposite and free side surfaces located in a pair of planes which, at least approximately, are parallel and at right angles to the adhering body surfaces, said apparatus comprising first jaw means operative to frictionally engage one side surface of one of the two bodies, second jaw means operative to frictionally engage the corresponding side surface of the other body, counterholding means operative to engage the opposite side surface of the two bodies, holder means connected to said first and second jaw means and common to them, actuator means for varying the distance between said holder means and said counterholding means and operatable to forcibly rEduce the distance between said holder means and the bodies, and means movably connecting said holder means to each of said first and second jaw means in a manner to bring about forced spreading of said jaw means after their engagement with the two bodies, when the distance between said holder means and the bodies is reduced.
Claim 2
Independent Claim 186 words
An apparatus for forcing apart a pair of bodies which adhere to each other with substantially planar surfaces and both of which have two opposite and free side surfaces located in a pair of planes which, at least approximately, are parallel and at right angles to the adhering body surfaces, said apparatus comprising first jaw means operative to frictionally engage one side surface of one of the two bodies, second jaw means operative to frictionally engage the corresponding side surface of the other body, counterholding means operative to engage the opposite side surface of the two bodies, holder means connected to said first and second jaw means and common to them, actuator means for varying the distance between said holder means and said counterholding means and operatable to forcibly rEduce the distance between said holder means and the bodies, and means movably connecting said holder means to each of said first and second jaw means in a manner to bring about forced spreading of said jaw means after their engagement with the two bodies, when the distance between said holder means and the bodies is reduced.
Claim 3
Dependent Claim 36 words
An apparatus as claimed in claim 1 wherein said holder means are connected to said actuator means to be moved towards and away from said counterholding means and, hence, relative to the bodies to be parted.
Claim 4
Dependent Claim 49 words
An apparatus as claimed in claim 1 wherein said connecting means comprise at least one pair of arms diverging from said holder means towards their respective jaw means and yieldable to increase the angle between them to thereby increase the mutual distance between said first and second jaw means.
Claim 5
Dependent Claim 38 words
An apparatus as claimed in claim 3 wherein said arms are rigid links hingedly connected to said holder means in a toggle-joint fashion, means being provided on said holder means to define a minimum angle between said links.
Claim 6
Dependent Claim 23 words
An apparatus as claimed in claim 1 wherein said first and second jaw means have body-engaging, covered faces directed towards said counter-holding means.
Claim 7
Dependent Claim 18 words
An apparatus as claimed in claim 1 wherein said counterholding means comprise a pair of movable body-engaging jaws.
Claim 8
Dependent Claim 27 words
An apparatus as claimed in claim 6 wherein said counterholder jaws are movable to and from the bodies to be parted under the actuation of toggle-joint devices.
