To a/Z whom it may concern:
Beit known that I, OTTO WILHELMI, a citi- Zen of the Swiss Republic, residing at Ksnacht, near Zurich, Switzerland, have invented new and useful Improvements in Coverings for Cables and Similar Devices, of which the following is a specification.
This invention relates to an improved covering for cables, wires, pi es, and other transmitters which is strong, eXible, and tight, so as to effectively shield the inclosure against moisture and other injurious influences.
In the accompanying drawings, Figure l is a side view of a cable, showing the covering in section; Fig. 2, a plan thereof Fig. 3, a cross-section on line A B, Fig. 2. Fig. 4 is a plan of the covering, showing it spread out in a plane; and Fig. 5, a side view of a cable, showing two layers of the covering in section.
The letter a represents a flexible sheet or wrapper adapted to be wound around a cable lc and composed of taraper or other Waterproof material. Into t e wrapper a are woven a series of parallel flexible metal bands b by being passed alternately upward and downward through transverse slits a of the wrapper.
nately over the top and bottom of the Wrapper, so that in this way the entire wrapper is Each band b thus projects alter-V armored, though free to bend in a longitudinal direction between adjoining bands. The transverse slits a/ of adjoining bands break line with each other, as shown, to prevent an undue weakening of the wrapper along transverse lines.
Hy improved covering is especially adapted for underground cables, water-pipes, gaspipes, and drains and effectively protects the same against frost, moisture, and other urious influences.
What I claim isi l. A rotective covering for cables and similar evices, composed of a waterproof wrapper having transverse slits, and of arallel metal strips passing through said sits, substantially as specified.
2. A protective covering for cables and similar devices, composed of a waterproof wrapper having transverse slits arranged to break line, and of parallel metal strips passingd through said slits, substantially as speci- Signed by me at Zurich, Switzerland, this 16th day of March, 1905.
