Formed end sections of the blank provide eyes for receiving the U-bolt ends. The middle layer is formed with a slightly smaller pipe engaging radius so as to act as a pressure ridge for sealingly deforming the pipe sections during clamping of the pipe joints. The outer contour of the saddle member is also radiused to minimize the envelope of the assembled pipe clamp without compromising the rigidity of the saddle member to the clamping forces.Type: GrantFiled: September 14, 1977Date of Patent: February 27, 1979Inventor: J. Ted Beebe

Patent number: 4122586Abstract: U-bolt clamp saddle for pipe joints, such as automobile exhaust pipes, is formed from a stamped sheet metal blank. The saddle includes two mirror-image halves integrally joined and folded along their "bottom" edge. Symmetrical deformations forming the U-bolt sleeves and rigidifying the blank are provided. The sleeves are hexagonal in cross-section. The halves are spot-welded face-to-face after folding.Type: GrantFiled: July 19, 1976Date of Patent: October 31, 1978Inventor: Carl Nothdurft

Patent number: 4063336Abstract: A clamp for heavy-duty use such as in clamping the telescoped tubing parts of exhaust systems of internal combustion engines. The clamp comprises a saddle portion including an arcuate pressure-applying edge adapted to engage the tubing and a conventional U-bolt that is adapted to engage the tubing diametrically opposite the pressure-applying edge of the saddle.The clamp saddle is made up of two very similar sheet metal members that are stamped in a suitable die or dies. Each member has a pair of spaced apart semicylindrical grooves formed therein, one along each opposite end of the member, there being an integral flange extending beyond each groove. One flange is wider than the other. Two of these sheet metal members are engaged face to face and the wider flanges bent over in reversed engagement upon the narrower flange of its opposite member. One of the engaged members has a tab integral with its upper edge that is also bent over into the upper edge of the other member in reversed engagement.Type: GrantFiled: January 5, 1977Date of Patent: December 20, 1977Assignee: Mercury Metal ProductsInventors: W. Richard Jones, Harry J. Kraig

Patent number: 4063700Abstract: A device for clamping tubular members such as an exhaust pipe with a muffler, wherein interengaging telescoped portions are clamped together by saddle members having semicircular portions adapted to apply circumferential pressure uniformly about the telescoped portions by means of a square U-bolt.Type: GrantFiled: March 11, 1976Date of Patent: December 20, 1977Inventor: Bill J. Brewer

Patent number: 4056869Abstract: A muffler clamp of the type utilized to interconnect telescoping tubular cylindrical members employing U-bolt and saddle. The saddle is formed of a single sheet metal plate folded back upon itself at a rear edge wherein the superimposed portions together define a saddle having a concave, semi-cylindrical, clamping edge and lateral edges. Recesses are formed in the portions to define openings for receiving the legs of the U-bolt. The lateral edges of the saddle are welded with a continuous bead to maintain the saddle assembly.Type: GrantFiled: January 19, 1977Date of Patent: November 8, 1977Assignee: Sparton CorporationInventor: Benjamin J. Eisma, Jr.

Patent number: 4040152Abstract: A saddle for a U-bolt clamp formed with two similar sheet metal half sections spot welded together in face-to-face relation. The upper central portion of the web of the clamp is formed with a semicircular recess to accommodate one-half of the periphery of the joint between telescoped tubes. At laterally opposite sides thereof the saddle is formed with parallel upright tubular portions adapted to slideably receive the legs of a U-bolt which surrounds the other half of the tube joint. The lower edge of the saddle, and optionally the edge of the semicircular recess, is formed with reinforcement flanges turned outwardly in opposite directions from the plane of the web of the saddle.Type: GrantFiled: January 7, 1977Date of Patent: August 9, 1977Inventor: Carl Gilgallon
