US 2008/0164692 A1 · CLAMPING APPARATUS FOR SUPPORTING AND SEALING JOINED PIPES

Abstract

An apparatus for supporting and sealing connections made between male and female cylindrical metallic dryer vent pipes is described. An elongated cylindrical clamping apparatus having a longitudinal opening through the surface thereof permitting the apparatus to be opened to encircle joined pipe members, and including clamping straps and optionally a rubbery sealing material disposed inside of the clamping apparatus to provide an improved gas seal permits the connection to be firmly held together without using rivets or screws. For pipe connections where an elbow is involved, two elongated cylindrical clamping devices may be used, and additional screw-type straps may be employed to connect the two devices with one or more straps being disposed over the heal of the elbow, and at least two straps crisscrossed over the throat of the elbow for added stability.

An apparatus for supporting and sealing a joint formed from a male portion of a first cylindrical dryer exhaust pipe inserted into a mating portion of a second cylindrical dryer exhaust pipe, wherein said male portion has a circumferential raised bead for limiting the distance said male portion can be inserted into said mating portion, said apparatus comprising in combination:

(a) an elongated cylindrical band having a chosen length, an inside surface, an outside surface, and having a first open end adapted to receive a portion of said first pipe and a second open end adapted to receive the female portion of said second cylindrical dryer exhaust pipe, said cylindrical band further having a longitudinal opening through its surface along the entire length thereof defining a first edge and a second edge and a concave circumferential portion approximately equidistant between the first open end and the second open end in the inside surface adapted for engaging the circumferential raised bead of said male pipe;
and
(b) means for clamping said cylindrical band around the portion of said first pipe and the portion of said second pipe, whereby said first pipe and said second pipe are firmly held together.

An apparatus for supporting and sealing a first joint formed from a male portion of a first cylindrical dryer exhaust pipe inserted into a mating portion of a dryer exhaust pipe elbow, and a second joint formed from a male portion of said elbow inserted into a mating portion of a second cylindrical dryer exhaust pipe, said apparatus comprising in combination:

(a) a first elongated cylindrical band having a chosen length, an inside surface, an outside surface, and having a first open end adapted to receive a portion of said first cylindrical dryer exhaust pipe and a second open end adapted to receive a mating portion of said elbow, said first cylindrical band further having a first longitudinal opening through its surface along the entire length thereof defining a first edge and a second edge;
(b) a second elongated cylindrical band having a chosen length, an inside surface, an outside surface, and having a third open end adapted to receive a second portion of said elbow and a fourth open end adapted to receive the mating portion of said second cylindrical dryer exhaust pipe, said second cylindrical band further having a second longitudinal opening through its surface along the entire length thereof defining a third edge and a fourth edge;
(c) first means for clamping said first cylindrical band around the portion of said first pipe and the mating portion of said elbow, whereby said first pipe and said elbow are firmly held together;
and
(d) second means for clamping said second cylindrical band around the second portion of said elbow and the mating portion of said second pipe, whereby said second pipe and said elbow are firmly held together.
