Definitions

• Patented Oct. 7, 1941 OFFICE CABLE SHEATH PROTECTOR C. E. Lewis Kerchner, York, Pa., assignor of sixty per cent to John Rupprecht, York, Pa.
• the present invention aims to supply a means whereby wear of the kind indicated may be obviated.
• Fig. 1 shows a device constructed in accordance with the invention, together with the supporting pole and attendant parts;
• Fig. 2 is a cross section on the line 2-2 of Fig. 1;
• Fig. 3 is a plan showing a modified form of the invention, parts being in section.
• a support such as a pole l, to which is secured a bracket 2, whereon is mounted a flexible carrying line 3, often referred to as the messenger cable, engaged by the oppositely facing hooks 4 of loop-shaped hangers 5, receiving a cable 6, provided with a sheath 1, made of lead or some other soft material.
• a flexible carrying line often referred to as the messenger cable
• the covering 8 may be slipped on endwise, over the cable, but the protector has resiliency enough so that its convolutions may be separated, thereby enabling the covering 8 to be cork-screwed upon the cable.
• the main cable is carried by the hangers 5, from the messenger line 3, the hangers being spaced about eighteen inches or so apart, most or" the weight is at the pole, and wear is greatest there.
• the present invention will do away with wear on the sheath '1, from the hangers 5, and will consummate the objects set forth in the opening portion of this specification.
• Fig. 3 parts hereinbefore described have been designated by numerals already used, with the suifix 0;.
• the cable may make a short turn, and the convolutions of the single spiral covering 8a may tend to open, as indicated at 9, under which circumstances, the hangers 5 would have access to the sheath la. of the cable and wear the cable.
• the covering Ba another covering l0, constructed like the covering 8a, but wound spirally in an opposite direction, the covering [6 bridging the spaces between the separated convolutions of the covering 8a and preventing the hangers So from coming into contact with the sheath la.
• the device is simple in construction, but practical and advantageous.
