1. A device for coupling aligned piping comprising:
(a) an adjustable means of temporarily gripping opposite sides of a pipe having a female-end;
(b) an adjustable means of temporarily gripping opposite sides of a separate pipe having a male-end aligned with the female-end;
(c) a means of leveraging the male-end into the female-end, including a leverage handle;
(d) a plurality of legs leveragingly linking said male-end gripping means to said leveraging means; and
(e) a plurality of arms fulcrumatically linking said female-end gripping means to said leveraging means, between said leveraging
linkings and said leverage handle;
(f) a span affixed to a lower end of said leverage handle and comprising a span length from a first span-end to a second span-end
at least slightly larger than the diameter of the pipes to be coupled, a first leverage plate downstanding from said first
span-end and defining a first intermediate hole, and a second leverage plate downstanding from said second span-end and defining
a second intermediate hole; said arms comprising a first arm defining a first leverage-end hole, and a second arm defining
a second leverage-end hole, said fulcrumatic linking of said female-end gripping means to said leveraging means comprising
a first fulcrum pin impaling said first leverage-end hole and with said first fulcrum pin in said first leverage-end hole
located between the handle and said first leverage plate, and a second fulcrum pin impaling said second leverage-end hole
and with said second fulcrum pin in said second leverage-end hole located between the handle and said second leverage plate,
said first leverage plate and second leverage plate capable of straddling a pipe and its respective coupling end along a respective
first side and second side; wherein movement of said leverage handle from a starting position toward the female-end to an
ending position toward the gripped male-end leverages the male-end into the gripped female-end.
