Crimping tool with third handle and method of use
View Patent ↗In a preferred embodiment, an apparatus, including: first and second handles; first and second crimping jaws operatively connected, respectively, to the first and second handles, such that moving the first and second handles toward each other causes the first and second crimping jaws to advance toward each other thereby to crimp a band around tubing or pipe; and a third handle rotatably attached to the first handle, such that a user of the apparatus manually moves the first handle toward the second handle by grasping the second handle and the third handle and moving them toward each other. A method of using the apparatus is also provided.
1. An apparatus comprising:
a first handle having a pivot, the handle having a side with a first opening positioned adjacent the pivot;
a second handle coupled to the first handle by the pivot;
a first crimping jaw operably coupled to the first handle;
a second crimping jaw operatively coupled to the second handle, wherein moving said first handle and said second handle from a first position to a second position causes said first crimping jaw and said second crimping jaw to advance toward each other thereby to crimp a band around tubing or pipe;
a third handle rotatably attached to said first handle between said first handle and said second handle;
an engaging lever operably coupled to the first handle;
a ratchet coupled to the second handle and operably coupled to the engaging lever, the ratchet having a body with a projection extending from one side, the ratchet further having a plurality of teeth along the side and the projection, wherein the projection extends into the first opening when in the second position;
a first biasing member disposed between the first crimping jaw and the second crimping jaw, wherein the first biasing member is a compression spring; and
a second biasing member disposed between the first handle and the second handle, wherein the second biasing member is a torsion spring disposed about the pivot.
