Abstract
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.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
132 words
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.
Claim 2
Dependent Claim
132 words
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.
Claim 3
Dependent Claim
23 words

Claim 5
Dependent Claim
29 words
The wire clamp of claim 1, said encircling wire means comprising a first wire and a second wire, said hose penetrating means being on at least one said wire.
Claim 6
Dependent Claim
16 words
The wire hose clamp of claim 4, said hose penetrating means being on two said wires.
Claim 7
Dependent Claim
26 words
The wire hose clamp of claim 1, said hose penetrating means being inclined to a plane passing transversely of the axis of an encircling wire means.
Claim 8
Dependent Claim
37 words
The wire hose clamp of claim 6, said encircling wire means comprising a first wire and a second wire, said hose penetrating means being at least on said first wire and being inclined towards said second wire.
Claim 9
Dependent Claim
44 words
The wire hose clamp of claim 1, said encircling wire means comprising a first wire and a second wire, said first wire having hose penetrating means thereon inclined to a plane passing through the axis of said first wire, and towards said second wire.
Claim 10
Dependent Claim
15 words
The wire hose clamp of claim 8, said second wire having hose penetrating means thereon.
Claim 11
Dependent Claim
34 words
The wire hose clamp of claim 9, hose penetrating means on said second wire being inclined to a plane passing transversely of the axis of said second wire and away from said first wire.
Claim 12
Dependent Claim
27 words
The wire hose clamp of claim 1, and in combination therewith a hose, said hose penetrating means extending through less than the entire thickness of said hose.
Claim 13
Dependent Claim
27 words
The combination of claim 11, said hose comprising inner and outer layers of elastomeric material, said hose penetrating means comprising barbs extending into said outer layer only.
Claim 14
Dependent Claim
28 words
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.
Claim 15
Dependent Claim
84 words
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.
Claim 16
Dependent Claim
84 words
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.
Claim 17
Dependent Claim
29 words
The wire hose clamp of claim 14, said barbs extending at an angle to the plane passing transversely of the axis of said first wire towards said second wire.
Claim 18
Dependent Claim
35 words
The wire hose clamp of claim 15, said barbs having a height from the inner part of said encircling wire less than the thickness of a hose when said wire is assembled on said hose.
Claim 19
Dependent Claim
35 words
The wire hose clamp of claim 14, said barbs having a height from the inner part of said encircling wire less than the thickness of a hose when said wire is assembled on said hose.
Claim 20
Dependent Claim
89 words
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.
Claim 21
Dependent Claim
20 words
The hose clamp of claim 18, said hose penetrating means comprising at least one barb extending from said clamping means.
Claim 22
Dependent Claim
35 words
The hose clamp of claim 19, said barb extending through less than the entire thickness of the hose, and being inclined to a plane extending through the clamping means and perpendicularly to the axis thereof.
