MARKING INSULATED WIRE.

APPLICATION FILED 0CT.5. 1915.

CABLE COMPANY, NECTICUT.

To all whom it may concern Be it known that'I, THOMAS J. SEWARD, a

citizen of the United States, residing at' the city of Bridgeport, county of Fairfield, State of Connecticut, have invented certaln new and useful Improvements in Marking Insulated Wire; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention pertains to an improved marking for insulated wire, and to 4 the method of producing such marking.

Insulated wires or wire cables are not readily marked, and the present invention has for its object to provide a" simple and eflicient method whereby the cable or sheathed wire may be easily marked, and that without injury to the fibers or threads which form the outer covering for the wire.

Several means have heretofore been devised for placing indicating marks upon the sheathing of the wire, as for instance, coloring certain portions of the threads which enmanxme msunargp WIRE.

ter into the braided covering, which colored portions, owing to their position in the covering produce certain designations or marks. Under such process it is necessary that the color be such as to contrast with the main body of the sheathing or covering, and where the wire and. its sheathing. are subjected to treatment by an insulating compound, usually dark, such marking would be obliterated. Under the present process no such previous formation or marking of the threads, which enter into the sheathing- (usually braided) is necessary, and the is illustrated in the annexed drawings,

' wherein:

In the drawings, 1 denotes a standard,"

surmounting a suitable base 2, the standard having ournaled thereon a wheel 3, provlded wlth a peripheral groove 4, semi-circular in cross-section. Fulcrumed upon the Patented Aug. 8, 31916. ipplioation flled October 5, 1915. Serial N6. 54,231.

in, the outer face of the die conforming to a the contour of the groove 7 and carrying type or other designating markers, which project outwardly to a slight extent from the face of the die, such type being shown in Fig. 2 but omitted from Fig. 1, owing to the fact that they are relatively small and incapable of being clearly shown in said figure. The rear or opposite end of the arm or lever 5, or an extension or arm 5 thereof, carries an adjustable counterweight 10, whereby the pressure of the wheel' or roll 6,

and consequently the die, upon the wire or cable 8 may be regulated as required.- While but one die is shown, it is evident that any number may be mounted upon the wheel 6, and consequently the impression made upon the wireor cable spaced as desired.

Secured to the standard 1 is a guide or quill 11, through which the .cable is passed from any suitable source'of supply to and between the

Wheels

3 and 6, the Wire being, of course, seated in the grooves of the wheels and drawn forwardly between the same as it is wound upon a spool or reel, not shown.

In order to prevent the die from injuring or cutting the insulation, or more strictly speaking, the threads which are braided upon the outer surface thereof, the wire is run between the wheels while the insulating material, with which the braided covering is impregnated, is still soft. In this way, the die may slightly distort-or push aside the fibers or threads, and thus not cut the same, as is likely to be the case where the material in which the threads are embedded or by which they are treated becomes hard, or relatively so. The marking of the material while in this relatively soft state also has the advantage of not dulling the dies, inasmuch as the material readily flows therefrom under pressure.

The marking produced upon the wire or cable is almost indestructible and permanent; there are no protrusions formed upon the Wire and, as just stated, the-insulation as such is not injured. Not only can the size of the wire be imprinted thereon, but the trade name of the wire and the name of the manufacturer may also be placed thereon, and this at any desired intervals. Again, the operation of marking the wire is a continuous one, and after the feed of the Wire is started it need not be stopped until the supply thereof is exhausted.

Having thus described the invention, what is claimed is: r

1. The method of marking preformed i11- sulated wire having a fibrous covering impregnated and coated with insulating material, which consists in indenting a designating mark into the outer face of the insulating covering while the insulating material is in a relatively soft state or condition.

2. The method of marking preformed insulated wire, which consists in passing such wire into operative relation with a periodically-acting indenting or marking die, and thereby impressing 1n the insulating surface, and without reformation of the insulating body, a series of designating marks.

3. The method of marking insulated wire, having a fibrous covering impregnated with insulating material, which consists in indenting a designating mark into the outer face of the insulating covering while the insulating material is in a relatlv'ely soft state or condition, whereby the fibers or threads of the covering will be displaced sufiiciently to prevent injury thereto.

4. The method of marking insulated wire, having a braided exterior treated with an insulating compound, which consists in indenting or impressing the outer surface thereof while the insulating compound is in a relatively soft condition, and thethreads of the braided portion are free to move under the action of the indenting or impressing element.

5. The herein-described process of marking preformed insulated wire, consisting in impressing, and without reformation of the insulating body, identifying marks at intervals through its length, while the insulating material is in such condition that it is free to be slightly displaced and to maintain such displacement without further treat ment upon the withdrawal of the indenting or impressing element.

6. The method of marking preformed insulated wire, which consists in feeding the wire, while the insulation is in a relatively soft state, to marking means; subjecting said wire intermittently, during the feeding operation, to the action of such means; and removing the latter from the wire at all times except during the periods of marking.

In testimony whereof I affix my signature in presence of two witnesses.
