Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
152 words
A clamp for sealing a telescoping engagement between a deformable cylindrical hose and a cylindrical metal member inserted in said hose including an arcuate member encircling said hose at the area of telescoping engagement, means on said arcuate member for drawing said arcuate member together arcuately to form at least a 360* circle and for placing said arcuate member under tension after it is drawn arcuately together, and means on said arcuate member to seal said hose and said cylindrical member around their area of telescoping engagement including a centrally disposed, radially inwardly facing, arcuate head and flanges extending outwardly from said head in opposite directions at an angle to the radially inwardly facing surface of said head of less than 180* creating a pair of spaced parallel sealing inducing edges on said arcuate members in spaced parallel relationship to each other and to said head on opposite sides of said head.
Claim 2
Dependent Claim
152 words
A clamp for sealing a telescoping engagement between a deformable cylindrical hose and a cylindrical metal member inserted in said hose including an arcuate member encircling said hose at the area of telescoping engagement, means on said arcuate member for drawing said arcuate member together arcuately to form at least a 360* circle and for placing said arcuate member under tension after it is drawn arcuately together, and means on said arcuate member to seal said hose and said cylindrical member around their area of telescoping engagement including a centrally disposed, radially inwardly facing, arcuate head and flanges extending outwardly from said head in opposite directions at an angle to the radially inwardly facing surface of said head of less than 180* creating a pair of spaced parallel sealing inducing edges on said arcuate members in spaced parallel relationship to each other and to said head on opposite sides of said head.
Claim 3
Dependent Claim
47 words
The invention as set forth in claim 1, wherein said arcuate member includes a pair of arcuate segments complementary in cross-sectional dimension and coupled together adjacent one arcuate extremity to each segment in radially flush engagement against relative movement between said segments at the area of coupling.
Claim 4
Dependent Claim
34 words
The invention as set forth in claim 2, wherein the means for drawing said arcuate member together arcuately and for placing said arcuate member under tension are disposed on one of said arc segments.
Claim 5
Dependent Claim
133 words
The invention as set forth in claim 3, wherein said means for drawing said arcuate member together arcuately and for placing said arcuate member under tensioN includes a pair of spaced parallel flanges, one located at each arcuate extremity of one of said arc segments, said flanges being generally co-extensive and each provided with a generally centrally disposed circular aperture, said apertures being axially aligned and being adapted to receive therethrough an elongated threaded bolt having a slotted head at one end, a biasing means on said bolt between said head and one of said flanges and a nut threadably engaged with said bolt at the end thereof remote from said head on the side of the remaining of said flanges facing in a direction opposite to the direction of said bolt head.
