Tool for inserting plastic flexible hose to fittings

An insertion tool for inserting a fitting to a hose comprising a main housing having a handle and a translating rod oriented in parallel relationship,

• a trigger pivotally attached to said handle,
• a spring between said handle and said trigger biasing said trigger away from said handle,
• a bell crank mounted in said main housing and pivoted at one end by a pivot thereto,
• a connecting link having one end pivotally connected to said trigger by a second pivot and the opposing end pivotally connected to one end of said bell crank by a third pivot,
• a pin mounted on another end of said bell crank,
• an actuator lever operatively connected to said translating rod and said pin for translating said translating rod in a first direction,
• a release lever operatively connected to said translating rod to release said translating rod to permit said translating rod to translate opposite said first direction,
• a hose holder attached to said housing and adapted to support a hose,
• a fitting holder attached to said translating rod and being oriented to be in line with said hose wherein operation of said trigger causes said translating rod and said fitting holder to position said fitting into said hose, and
• wherein said first pivot is disposed between said second pivot and said pin whereby said mechanical advantage is enhanced and said insertion tool is operable to insert a fitting into a hose when said hose is disposed in the ground.

In combination, an insertion tool comprising a main housing having a handle and supporting a translating rod for rectilinear movement and being oriented in parallel relationship,

• a trigger pivotally attached to said handle,
• a spring between said handle and said trigger biasing said trigger away from said handle,
• a bell crank mounted in said main housing and pivoted at one end by a pivot thereto,
• a connecting link having one end pivotally connected to said trigger by a second pivot and the opposing end pivotally connected to one end of said bell crank by a third pivot,
• a pin mounted on another end of said bell crank,
• an actuator lever operatively connected to said translating rod and said pin for translating said translating rod in a first direction,
• said actuator lever having a spring bearing there-against for biasing said actuating lever in a non-operable position,
• a release lever operatively connected to said translating rod to release said translating lever to permit said translating rod to translate opposite said first direction,
• said spring bearing against one face of said release lever,
• another spring bearing on another face opposite said one face on said release lever and biasing it in an operative position, wherein when said release lever is positioned, said other spring is compressed by said release lever so as to permit the translating rod to be repositioned in a direction opposite said first direction,
• a hose holder attached to said housing and adapted to support a hose,
• a fitting holder releasably attached to said translating rod and being oriented to be in line with said hose wherein operation of said trigger causes said translating rod and said fitting holder to position said fitting into said hose and said fitting holder being changed to accommodate different shaped and sized fittings, and
• wherein said first pivot is disposed between said second pivot and said pin whereby said mechanical advantage is enhanced and said insertion tool is operable to insert a fitting into a hose when said hose is disposed in the ground.
