Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
225 words
A device for separably connecting two elements end-to-end, comprising: a. a generally cylindrical member adapted to be secured to the end of one of the elements, b. a generally cylindrical body adapted to be secured to the end of the other element, c. means for locking said member and body in coaxial relation against axial movement away from each other, d. means movable axially with respect to said body to release said locking means and permit separation of said member and body, e. a fitting fixed to said means (d), f. two lever means relatively movable toward and away from each other in a direction transverse to the axes of said member and body, said lever means being carried by said fitting and movable with respect thereto, and each lever means being arranged at an acute angle with respect to the axes of said body and member, said angle opening toward the end of said body adapted to be connected to its respective element, whereby said lever means can be gripped by a mechanical hand and moved toward each other, and g. means carried by each lever means responsive to movement of said lever means toward each other for together applying substantially symmetrical axial forces to said body for producing relative axial movement between the body and said means (d) thereby releasing said locking means.
Claim 2
Independent Claim

Claim 3
Dependent Claim
15 words
A device as set forth in claim 1 wherein said fitting is a cylindrical ring.
Claim 4
Dependent Claim
34 words
A device as set forth in claim 2 wherein each of said lever means is tangential to said ring, is mounted to pivot thereon about a radial axis, and carries an unlockiNg cam surface.
Claim 5
Dependent Claim
37 words
A device as set forth in claim 1 wherein each of said lever means is a bent lever having a short axially moving unlocking arm serving as said means (g), and a longer radially moving maneuvering arm.
