Abstract
A wire hose clamp has barbs extending from at least one of the encircling wires forming a part of the hose clamp. The barbs extend in the direction of rotation in which the clamp is urged by the application of a tool to tighten the clamp, and may be inclined to the plane containing the axis of the wire.
Claims20
A wire hose clamp comprising:
- (a) encircling wire means for clamping a compressible hose,
- (b) means for causing said encircling wire means to be contracted including a tangentially extending operating element having a tool engaging head, said clamp being urged to rotate on the hose when force is applied to said tool engaging head by a tool to tighten said clamp, and
- (c) hose penetrating means for penetrating a hose to which said clamp is applied extending from said wire clamping means in a direction between tangential thereto and radially thereof and in the direction of rotation of said clamp when urged by a tool applied to said tool engaging head, whereby said penetrating means penetrates into said hose upon rotation of the clamp when urged by a tool engaging said head.
The combination of claim 13, said hose further comprising an intermediate fabric layer between said inner and outer elastomeric layers, said barbs extending substantially to said fabric layer.
A wire hose clamp comprising:
- (a) first and second encircling clamping wires,
- (b) screw threaded means engaging said wires for contracting said wires upon rotation thereof, said screw threaded means including a tool engaging head for effecting rotation thereof, and
- (c) barbs extending from at least one of said wires at an angle between tangential and radial with respect to said wire and inclined in the direction of rotational movement of said hose clamp due to a force applied to said tool engaging head.
A hose claimp comprising:
- (a) encircling, contractable clamping means for extending about and clamping a hose,
- (b) means for contracting said clamping means comprising a tangentially-extending operating element having a tool-engaging head, and
- (c) hose penetrating means for penetrating a hose to which said clamp is applied extending from said clamping means in a direction between tangential and radial and in the direction of rotation of said clamp when urged by a tool applied to said tool engaging head for moving said operating element to contract said clamping means.
