Abstract

A tool for removing a retaining cap from a hose clamp has a handle to which is attached a retaining cap nest having a cap receiving portion for receiving the capped ears of the hose clamp, an opening in an end of the receiving portion for accepting an uncapped portion of the capped ears, and a pair of lands, one on either side of the opening, for pushing against the legs of the cap during removal from the ears. In one embodiment, the nest has a pair of symmetrically shaped half-sections attached to the jaws of a locking pliers type tool which are placed around the capped ears. When the handles of the tool are squeezed together, a nest is formed capable of retaining the cap after removal from the ears. A preferred embodiment has a handle with a hollow cylindrical jacket attached thereto surrounding a pneumatically operated rod to which is affixed a unitary nest. When in an extended position, the nest can be positioned to grasp the hose clamp retaining cap in the receiving portion. The nest is then pneumatically retracted within the jacket thus removing and holding the retaining cap, and allowing the clamp to compress around a hose to which it is attached.

A hose clamp retaining cap removal tool for grasping and removing a retaining cap from a pair of radially extending ears at the distal ends of a hose clamp and holding the retaining cap after removal from the ears, the tool comprising:

(1) a handle;
(2) means for removing said retaining cap from said ears when capped comprising a rod attached to said handle, said rod extendable and retractable along a line parallel to an axis between a front of said tool and said handle with;
(3) retaining cap nest attached to said rod having
(a) retaining cap receiving portion for receiving said ears when capped;
(b) an opening an an end of said receiving portion for accepting an uncapped portion of said ears when capped;
and
(c) pair of lands located on the interior of said retaining cap receiving portion, one of said pair of lands located on a first side of said opening and the other of said pair of lands located on a second side of said opening, with said lands being adapted to abut the retaining cap, so as to cause the cap to become disengaged from the clamp when the tool is drawn away from the clamp;
and
(4) a pair of tool positioning members attached to the nest end of the tool for positioning the tool relative to the hose clamp and the ears when capped, one of said pair of positioning members located on a first side of said opening and the other of said pair of positioning members located on a second side of said opening.
