Joint-sealing hose

Claim 2

An elastomeric joint-sealing hose adapted to be inserted in the joint between a pair of members having parallel end walls, comprising a pair of elongate tubes each being defined by a continuous wall having the configuration of one-half of a longitudinally split circular cross-sectional hose, one portion of the wall of each tube being a half circle and the remaining portion of the wall of each said tube being defined by a first, longitudinally extending thin partition wall extending between and connecting the two ends of said half circle wall portion, two ends of said pair of tubes being interconnected and said first partition walls extending in the same direction from said connections in substantially parallel relationship whereby, upon insertion of the hose into the joint, the resistance to compression of each said tube will be increased as said first partition walls are each placed in tension to thereby improve the seal of the joint.

Claim 3

The hose according to claim 1 further comprising a pair of second, integral, longitudinally extending, thin partition walls within each said tube, each said pair of second partition walls connecting said first partition wall of each tube with each said half-circle wall partition and each of said second partition walls of each said pair lying obliquely to said first partition walls.

Claim 4

The hose according to claim 2 wherein a longitudinally extending head is provided along the interconnection between said tubes and along each said tube opposite said interconnection.

Claim 5

An elastomeric joint-sealing hose adapted to be inserted in the joint between a pair of members having parallel end walls, comprising a pair of elongate tubes each being defined by a continuous wall having the configuration of one-half of a longitudinally split circular cross-sectional hose, one portion of the wall of each tube being a half circle and the remaining portion of the wall of each said tube being defined by portions of a third and a fourth, longitudinally extending thin partition wall, two ends of said pair of tubes being interconnected, each of said third partition walls extending between and connecting one end of each said half circle wall portion with the inner side of each said half circle wall portion each of said fourth partition walls extending between and connecting the other end of each said half ciRcle wall portion with the inner side of each said half circle wall portion, said third and fourth partition walls being arranged to intersect along their respective centerlines whereby, upon insertion of the hose into the joint, the resistance to compression of each said tube will be increased as said partition walls are each placed in tension to thereby improve the seal of the joint.

Claim 6

An elastomeric joint-sealing hose adapted to be inserted in the joint between a pair of members having parallel end walls, comprising a pair of elongate tubes each being defined by a continuous wall having the configuration of one-half of a longitudinally split circular cross-sectional hose, one portion of the wall of each tube being a half circle and the remaining portion of the wall of each said tube being defined by portions of a third and a fourth, longitudinally extending thin partition wall, two ends of said pair of tubes being interconnected, each of said third partition walls extending between and connecting one end of each said half circle wall portion with the inner side of each said half circle wall portion each of said fourth partition walls extending between and connecting the other end of each said half ciRcle wall portion with the inner side of each said half circle wall portion, said third and fourth partition walls being arranged to intersect along their respective centerlines whereby, upon insertion of the hose into the joint, the resistance to compression of each said tube will be increased as said partition walls are each placed in tension to thereby improve the seal of the joint.

Claim 7

The hose according to claim 4 wherein a longitudinally extending bead is provided along the interconnection between said tubes and along each said tube opposite said interconnection.

Claim 8

An elastomeric joint-sealing hose adapted to be inserted in the joint between a pair of members having parallel end walls, comprising a pair of elongate tubes each of a constant circular cross section in tangential contact with one another, and being interconnected along one portion of their length by means of a longitudinally extending U-shaped rib on one side of the tangential contact area, each said tube having a longitudinally extending thin partition wall therein each extending between and connecting portions of the inner side of each said tube, said partition walls being so disposed so as to diverge away from said U-shaped rib whereby, upon insertion of the hose into the joint, the resistance to compression of each said tube will be increased as said partition walls are each placed in tension to thereby improve the seal of the joint.

Claim 9

An elastomeric joint-sealing hose adapted to be inserted in the joint between a pair of members having parallel end walls, comprising a pair of elongate tubes each of a constant circular cross section in tangential contact with one another, and being interconnected along one portion of their length by means of a longitudinally extending U-shaped rib on one side of the tangential contact area, each said tube having a longitudinally extending thin partition wall therein each extending between and connecting portions of the inner side of each said tube, said partition walls being so disposed so as to diverge away from said U-shaped rib whereby, upon insertion of the hose into the joint, the resistance to compression of each said tube will be increased as said partition walls are each placed in tension to thereby improve the seal of the joint.

Claim 10

The hose according to claim 6 wherein longitudinally extending ribs are provided along the outer surface of each said tube.

Claim 11

The hose according to claim 7 wherein the thickness of said partition walls are each substantially less than the thickness of each said tube.
