Abstract

Abstract A ring is constructed from a length of wire formed into a circle with the ends bent at right angle and tilted at an angle away from each other. The ends are flattened normal to the plane of the ring to form parallel flanges through which apertures are provided. The aperture in one of the flanges is threaded for supporting a screw of substantial length having a head at one end and a reduced cylindrical nib at the other end which extends into the aperture of the other flange. When the ends of the ring are offset and overlapped the nib at the end of the screw extends into the aperture in the other flange and due to the opposite angular tilt to the flanges the axis of the screw falls in a plane through the engaged sides of the ring. By advancing the screw through the threaded aperture the flanges are moved away from each other thereby tightening the ring about a tube to be sealed.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 166 words
In a ring clamp, a wire body shaped in the form of a circle with the ends bent at right angle in the plane of the ring to extend outwardly of the ring and bent laterally in opposite directions sidewardly of said plane, said ends being flattened to form flanges disposed in parallel relation to each other normal to the plane of the ring, each of said flanges having an aperture, the aperture through one flange having threaded means associated therewith, and a screw having a driving head at one end and a nib at the opposite end screwed into said threaded means with the nib extending above the wire body, the aperture through the other of said flanges receives said nib, the driving of the screw to increase the spacing of the flanges reduces the diameter of the ring to produce a clamping operation the flattened ends being so related that when disconnected are in Vrelationship and when connected by said screw are in Xrelationship.
Claim 2
Dependent Claim 166 words
In a ring clamp, a wire body shaped in the form of a circle with the ends bent at right angle in the plane of the ring to extend outwardly of the ring and bent laterally in opposite directions sidewardly of said plane, said ends being flattened to form flanges disposed in parallel relation to each other normal to the plane of the ring, each of said flanges having an aperture, the aperture through one flange having threaded means associated therewith, and a screw having a driving head at one end and a nib at the opposite end screwed into said threaded means with the nib extending above the wire body, the aperture through the other of said flanges receives said nib, the driving of the screw to increase the spacing of the flanges reduces the diameter of the ring to produce a clamping operation the flattened ends being so related that when disconnected are in Vrelationship and when connected by said screw are in Xrelationship.
