Patent ID: 7708317

Claim:
A pipe connector in combination with hollow solid metal pipes that form piles when driven into the ground, said pipe connector interconnecting opposed ends of two of said hollow slid metal pipes in end-to-end abutting relationship, said pipe connector comprising two flat solid plates of substantially rectangular contour and predetermined thickness, an elongated rectangular interconnecting slot in each said two flat solid plates extending along a central longitudinal axis thereof from an end edge of said plate to at least mid-length of said plate, said two flat solid plates being coupled to one another by mating said slots together, whereby said opposed ends of said plates are substantially aligned with said two flat solid plates disposed at right angles to one another, each said two flat solid plates having opposed flat outer side edges, an arresting raised projection extending outwardly from a respective one of said opposed flat outer side edges in a mid-section thereof, said arresting raised projections being transversely aligned with one another, each said flat outer side edges having opposed sloped edge portions extending from a respective side of said arresting raised projection and sloping inwardly to said opposed ends of each said two flat solid plates, said opposed sloped edge portions providing a friction fit connection in opposed ends of said two hollow solid metal pipes where said pipes are driven into the ground by an impact force with said pipe connector fitted between said opposed ends.
