Abstract
Abstract The invention relates to a hose of rubber or rubber-like elastic material adapted to convey pressurized medium and provided with a number of insulated, electrically conductive stranded metal wires embedded in the outer layer of the hose and contributing to its mechanical strength. Use of such a hose is desirable to transmit control signals or other electrical current from one end of the hose to the other by way of the stranded metal wires without obstructing the flexibility of the hose. An end connector means having a metal connector fitting, a shrunk-on sleeve in contact with the metal connector fitting, and a protective cover around the hose itself provides a means for joining the conducting hose to another flexible hose or suitable connecting member.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
197 words
A flexible pressure hose comprising: a hose member of a flexible material for conveying a pressurized medium; an outer layer of flexible material surrounding said hose member; a plurality of electrically conductive, stranded metal wires separately embedded in the outer layer of flexible material and extending substantially the length of the hose member, said stranded metal wires extending out of said outer layer at an end area thereof; a connector means attached to at least one end of the hose member comprising a first protective cover circumferentially surrounding the hose member in said end area where the stranded metal wires extend out of the outer layer and providing an area for the attachment of the hose member to a passageway for pressurized medium, a second protective cover integral with said first protective cover circumferentially surrounding the stranded metal wires and providing an area for attachment of the stranded metal wires to a means for conducting electric current, a metal connector fitting attached to the end of the hose member and a shrunk-on sleeve within the first protective cover and substantially surrounding the hose member and extending to contact at least a portion of the metal connector fitting.
Claim 2
Dependent Claim
197 words
A flexible pressure hose comprising: a hose member of a flexible material for conveying a pressurized medium; an outer layer of flexible material surrounding said hose member; a plurality of electrically conductive, stranded metal wires separately embedded in the outer layer of flexible material and extending substantially the length of the hose member, said stranded metal wires extending out of said outer layer at an end area thereof; a connector means attached to at least one end of the hose member comprising a first protective cover circumferentially surrounding the hose member in said end area where the stranded metal wires extend out of the outer layer and providing an area for the attachment of the hose member to a passageway for pressurized medium, a second protective cover integral with said first protective cover circumferentially surrounding the stranded metal wires and providing an area for attachment of the stranded metal wires to a means for conducting electric current, a metal connector fitting attached to the end of the hose member and a shrunk-on sleeve within the first protective cover and substantially surrounding the hose member and extending to contact at least a portion of the metal connector fitting.
