Abstract
Abstract A clamp that can be rapidly operated to hold the ends of two pipes together so as to connect them, and which facilitates field repair when the clamp breaks. The clamp includes two indentical body members having hinge ends where they are hinged together and latch ends where they can be held together by a latch. The hinge end of each member has a pair of spaced hinge flanges, one located at one extreme side and the other located between the middle and other extreme side, to permit the pair of flanges on the two identical body members to be sandwiched into one another. A rubber seal is fastened to each body member, each seal extending slightly more than one-half circle, so that when the clamp is closed the ends of the seals on the two body members abut and compress against one another to form a tight seal. The latch end of each body member has a pair of laterally spaced strike flanges, and a latch lever passing between the strike flanges carries a latch member that clamps the strike ends together.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
162 words
A pipe coupling comprising: a pair of substantially identical and mutually interchangeable body members, each member having hinge and strike ends and extending in an arc of a half circle between said ends, said members being pivotally joined at their hinge eNds, each member having a pair of strike flanges on either side of its strike end and said strike flanges being spaced to leave a central gap between them; a latch lever having a first end disposed between and pivotally connected to the pair of strike flanges on a first of said body members, and having a second end; and a latch member having a bifurcated first end portion with a pair of laterally spaced parts engageable with a pair of said strike flanges, said second end of said lever disposed between and pivotally connected to said laterally spaced parts of said first end portion of said latch member, and said latch member having a second end portion forming a handle.
Claim 2
Dependent Claim
162 words
A pipe coupling comprising: a pair of substantially identical and mutually interchangeable body members, each member having hinge and strike ends and extending in an arc of a half circle between said ends, said members being pivotally joined at their hinge eNds, each member having a pair of strike flanges on either side of its strike end and said strike flanges being spaced to leave a central gap between them; a latch lever having a first end disposed between and pivotally connected to the pair of strike flanges on a first of said body members, and having a second end; and a latch member having a bifurcated first end portion with a pair of laterally spaced parts engageable with a pair of said strike flanges, said second end of said lever disposed between and pivotally connected to said laterally spaced parts of said first end portion of said latch member, and said latch member having a second end portion forming a handle.
Claim 3
Dependent Claim
105 words
The pipe coupling described in claim 1 wherein: each pair of strike flanges has aligned pin-receiving holes, and said latch lever has a first hole at said first end for receiving a pin (33) that projects through the pin-receiving holes of the pair of strike flanges on which the first latch lever end is pivotally mounted, and said latch lever has a second hole located so it is aligned with the pin-receiving holes of the other strike flanges when the latch lever is in a closed position, to permit the reception of a locking pin (43) that holds the latch lever in the closed position.
Claim 4
Dependent Claim
258 words
A pipe coupling comprising: a pair of identical body members (16, 18), each member having hinge and strike ends and extending in an arc of a half circle between said ends, the hinge end (20) of each member including a pair of laterally spaced hinge flanges (52, 54), one flange (54) located at one side of the hinge end and the other (52) located between the other side and the middle of the hinge end, and the hinge flanges of the two body members being sandwiched together and having holes for receiving a pivot pin; the strike end (24) of each body member having a pair of strike flanges (80, 82) on either side of its strike end that leave a central gap between the strike flanges, the pair of strike flanges of each body member having a pair of aligned pin-receiving holes and each strike flange having a latch receiving recess (42); a latch lever (28) having a first end (32) disposeable between the pair of strike flanges on one of said body members and having a pin-receiving hole for pivotal connection thereto, and having a second end (34); and a latch member (30) having a bifurcated first end portion (38) with a pair of laterally spaced parts engageable in the recesses (42) of a pair of said strike flanges, said second end (34) of said lever disposeable between and pivotally connectable to said laterally spaced parts (94, 96) of said first end portion, and said latch member having a second end portion (36) forming a handle.
Claim 5
Dependent Claim
258 words
A pipe coupling comprising: a pair of identical body members (16, 18), each member having hinge and strike ends and extending in an arc of a half circle between said ends, the hinge end (20) of each member including a pair of laterally spaced hinge flanges (52, 54), one flange (54) located at one side of the hinge end and the other (52) located between the other side and the middle of the hinge end, and the hinge flanges of the two body members being sandwiched together and having holes for receiving a pivot pin; the strike end (24) of each body member having a pair of strike flanges (80, 82) on either side of its strike end that leave a central gap between the strike flanges, the pair of strike flanges of each body member having a pair of aligned pin-receiving holes and each strike flange having a latch receiving recess (42); a latch lever (28) having a first end (32) disposeable between the pair of strike flanges on one of said body members and having a pin-receiving hole for pivotal connection thereto, and having a second end (34); and a latch member (30) having a bifurcated first end portion (38) with a pair of laterally spaced parts engageable in the recesses (42) of a pair of said strike flanges, said second end (34) of said lever disposeable between and pivotally connectable to said laterally spaced parts (94, 96) of said first end portion, and said latch member having a second end portion (36) forming a handle.
