Abstract: Herein are disclosed marking plates in which opposed edges of a plate are bent toward one another to define channels opening upon a mid-part of the plate. A row of strip-parts of uniform width, each bearing a symbol, are held to the plate by having marginal edge portions slideably held in the channels. The mid-part of the plate defines a row of mounting holes parallel to the channels such that each hole has a length, and the holes are separated by this length, equal to the width of the strip-parts. Thus, for any number of strip-parts held by the channels on the plate, the row of strip-parts may be centered so that at least half of a mounting hole extends on each end of the row of strip-parts, providing a locking orifice for securing the strip-parts to the plate and the plate to tubes, hoses, cables, and other objects.

Abstract: Marking tapes for marking articles is described. The marking tape consists of a tubular hose or cover of a soft and transparent material. The cross section of the hose or cover may be of circle or of rectangular form and have a diameter length being somewhat less than the width of marking plates to be inserted in the hose or cover. The hose or cover will be provided with spaced holes and/or lugs for fastening of the hose or cover onto articles. The ends of a single hose or cover may be furnished with end closures serving as to stiffen the end portions and having fastening holes for mounting the hose or cover onto the articles especially if the hose or cover is devoid of holes. The hose or cover is made from pre-fabricated carrier hose which is cut into sections or segments.
