Abstract
Abstract A flange member has a bearing surface for engaging a clamping surface of one flange of a pair of mating flanges. A pair of slots residing in opposite sides of the flange member are disposed above and at an angle oblique to the bearing surface. The flange member resides within a lock member and is slidably linked thereto by a pin projecting through each of the slots. A wedge resides in an opening in the flange member, above the bearing surface. An adjustable spacer means, bearing between the lock member and the wedge, urges the wedge and the pins into engagement with the other flange of the pair of mating flanges, providing three distinct areas of clamping.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
204 words
A clamp for interconnecting conduit sections having mating flanges with opposed clamping surfaces, the clamp comprising: a flange member And a lock member, said flange member residing within said lock member, said flange member including a bearing surface engageable with one clamping surface and including a pair of slots in opposite sides of the flange member, the slots being disposed at an angle oblique to the bearing surface and a downwardly inclined plane member extending at an angle substantially opposite to the first mentioned angle on the end of said flange member; said lock member including slot engagement means slideable in and projecting through the slots, and engageable with the other clamping surface; a spacer means including wedge means slideably engaging the downwardly inclined plane member and engageable with the other clamping surface, the spacer means residing between the lock member and the flange member, and adjustable means interconnecting said spacer means, said flange member and said lock member to adjust said flange member and said lock member relative to each other whereby to urge the slot engagement means along the slots toward the other clamping surface and to urge the wedge means toward the other clamping surface upon operation of said adjustable means.
Claim 2
Dependent Claim
204 words
A clamp for interconnecting conduit sections having mating flanges with opposed clamping surfaces, the clamp comprising: a flange member And a lock member, said flange member residing within said lock member, said flange member including a bearing surface engageable with one clamping surface and including a pair of slots in opposite sides of the flange member, the slots being disposed at an angle oblique to the bearing surface and a downwardly inclined plane member extending at an angle substantially opposite to the first mentioned angle on the end of said flange member; said lock member including slot engagement means slideable in and projecting through the slots, and engageable with the other clamping surface; a spacer means including wedge means slideably engaging the downwardly inclined plane member and engageable with the other clamping surface, the spacer means residing between the lock member and the flange member, and adjustable means interconnecting said spacer means, said flange member and said lock member to adjust said flange member and said lock member relative to each other whereby to urge the slot engagement means along the slots toward the other clamping surface and to urge the wedge means toward the other clamping surface upon operation of said adjustable means.
Claim 3
Dependent Claim
27 words
A clamp as defined in claim 1 in which the downwardly inclined plane member includes an incline plane means with which the wedge means is slieably engageable.
Claim 4
Dependent Claim
54 words
A clamp as defined in claim 1 in which the flange member includes a captive opening adjacent the downwardly inclined plane member having an angle of inclination generally greater than the angle of inclination of the slots, said wedge means substantially residing within the captive opening and slideably engageable with the inclined plane member.
Claim 5
Dependent Claim
68 words
A clamp as defined in claim 3 in which the wedge means in cross-section generally defines a right angle triangle, the hypotenuse of which is slideably engageable with the incline plane member, the wedge means also including a pair of lateral projections adjacent the end of the hypotenuse remote from said lock member and extending beyond opposite sides of the captive opening to loosely retain the wedge means.
Claim 6
Dependent Claim
34 words
A clamp as defined in claim 3 in which the angle of inclination of the slots and of the incline plane member is about 30* and 45* respectively with respect to the bearing surface.
