Abstract
Abstract A coupled joint of axially aligned elongated members, which members may be tubular members or solid rods, or may have rectangular transverse cross sections which are solid or hollow, has opposed flanges on the adjacent ends of the elongated members and a plurality of clamping bands or jaw members holding said flanges together in aligned abutting relationship. The opposed flanges may be formed integrally at the adjacent ends of the elongated members or may constitute portions of ferrules secured to the ends of said members. Said opposed flanges have squared end surfaces in abutting relationship with each other, opposed outwardly diverging surfaces and aligned peripheral surfaces. The jaw members have web portions peripherally embracing the flanges and a plurality of opposed pairs of fingers which extend substantially axially under the web portions and exert a viselike grip on the outwardly diverging surfaces of the flanges to maintain the flanges in aligned abutting relationship. Washers may be disposed between said outwardly diverging surfaces and the opposing ends of said fingers. A recess may be provided in each of said flanges to form a chamber of substantially trapezoidal axial section, and a gasket of similar axial section fills said chamber.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
329 words
A coupler for connecting one end of a first elongated member to one end of a second elongated member comprising, in combination, a first means carried by the first of said elongated members defining a first flange extending outwardly from the axis of the first elongated member, said first flange having a leading surface confronting the one end of the second elongated member and a trailing surface on the side of the first flange opposite the leading surface, the trailing surface of the first flange being at an angle to the axis of elongation of the first member less than a right angle, means carried by the second of said elongated members defining a second flange extending outwardly from the axis of the second elongated member, said second flange having a leading surface abutting the leading surface of the first flange and a trailing surface, the trailing surface of the second flange being at an angle to the axis of elongation of the second member less than a right angle, a jaw member engaging the first and the second flanges, said jaw member having a web disposed adjacent to the first and second flanges with a central axis generally aligned with the abutting leading surfaces of the first and second flanges and a plurality of fingers extending from the web on opposite sides of the central axis thereof, the fingers on one side of the central axis of the web having a first bend extending under the web and said fingers extending generally normal to and abutting the trailing surface of the first flange, and the fingers on the opposite side of the central axis of the web having a second bend extending under the web and said fingers extending generally normal to and abutting the trailing surface of the second flange, whereby the fingers of the jaw member retain the jaw member on the flanges and maintain the leading surfaces of the first and second flanges in abutment.
Claim 2
Dependent Claim
329 words
A coupler for connecting one end of a first elongated member to one end of a second elongated member comprising, in combination, a first means carried by the first of said elongated members defining a first flange extending outwardly from the axis of the first elongated member, said first flange having a leading surface confronting the one end of the second elongated member and a trailing surface on the side of the first flange opposite the leading surface, the trailing surface of the first flange being at an angle to the axis of elongation of the first member less than a right angle, means carried by the second of said elongated members defining a second flange extending outwardly from the axis of the second elongated member, said second flange having a leading surface abutting the leading surface of the first flange and a trailing surface, the trailing surface of the second flange being at an angle to the axis of elongation of the second member less than a right angle, a jaw member engaging the first and the second flanges, said jaw member having a web disposed adjacent to the first and second flanges with a central axis generally aligned with the abutting leading surfaces of the first and second flanges and a plurality of fingers extending from the web on opposite sides of the central axis thereof, the fingers on one side of the central axis of the web having a first bend extending under the web and said fingers extending generally normal to and abutting the trailing surface of the first flange, and the fingers on the opposite side of the central axis of the web having a second bend extending under the web and said fingers extending generally normal to and abutting the trailing surface of the second flange, whereby the fingers of the jaw member retain the jaw member on the flanges and maintain the leading surfaces of the first and second flanges in abutment.
