FLEXIBLE ELECTRICAL MOLDING Filed Nov. 6, 1926 1 VENTORS I 7 BYaWM ATTORNEY Patented June 7, 1932 UNITED STATES PATENT OFFICE HARRY WOLFSON AND FRANK ennsrnm, on NEW YORK, AND nanny ennsrnm, or

ARVERNE, NEW YORK FLEXIBLE ELECTRICAL MOLDING Application filed November This invention relates ,to flexible electrical molding.

Whenever the occupant of a building is desirous of leading an electrical wire from a cut-out box or socket and to secure the same to the walls of the building he is obliged to do so within a metal or wood molding, the reason being that tacks, brads or staples if utilized directly upon the wires are liable to abrade the insulation with the consequent possibility of short circuiting. Metal molding or Wood molding are also objectionable in that the services of an electrician is required, and they are generally unsightly and take up an unnecessary amount of space.

One of the objects of this invention is to provide a flexible molding that can be utilized and installed by any one for lead wires from a cut-out box or socket within a building. Still another object of the invention is to provide a flexible electrical molding capable of being bent in any) shape and having an apron to permit of it eing tacked to the wall or other parts of the building to carry electrical wiring. A further object of the invention is to provide an electrical molding which will be inconspicuous in that it will be smaller in diameter or width than the present moldingsvof metal or wood and will be furnished in diflerent colors to match the colors of the walls of the buildings. A further object of the invention is to provide a flexible electricalmolding cheap to manufacture and sell. Still another object of the invention is to provide a flexible electrical molding having a wire or wires imbedded in insulating and non-burning material within the flexible electrical molding.

In carrying out our invention, we propose to provide a flexible electrical molding 4 terminating in two flaps 5, 6, forming an apron 7. Flaps 5 and 6 are shown sewn together but they may be cemented or joined in any other well known manner. I preferably use a rubber coated material for the flexible electrical molding which may be made in difl'erent colors to conform to the decorations or color of the walls of the diterent buildings. The flexible electrical molding 4 is adapted to receive wires 1, 2, insulated at 3 in the usual manner but preterably having the rubber initial insulation about the ditferent wires of different colors where more than one wire is used.

In the modified form, one flap 5' is longer than the other 6, and is folded up around the shorter flap 6 and is then sewed or cemented together to form apron 7. This construction is slightly stronger but is not as neat in appearance as the preferred embodiment. In the case of an indoor aerial antenna wire the insulation about the wire may be omitted, if desired, and the flexible electrical molding may be stuffed with wool or hair 3' chemically treated to prevent burning.

With this form of flexible electrical molding, the extensive outside covering may be dispensed with and the wires simply rubber coated and inserted in the wool or hair which has been chemically treated within the flexibleelectrical molding. This invention is readily manufactured in that the rubberized fabric material and the wool or chemically treated hair are fed in long strips together with the wire into the machine which folds up the rubberized fabric material and wool about the wire, forming the apron and at the same time stitching the flaps of the apron. The molding is then sold in strips of any desired length completely assembled.

It will thus be seen that the flexible electrical molding is as easily handled as the ordinary wire and can be bent into any shape and does not require the services of an electrician to install. it is adapted to many uses, it is cheap to manufacture and is a much better fire risk than the customary wood molding and less liable to short circuiting than the metal molding.

What we claim is:

In an article of manufacture comprising i a wire, an insulating hair covering surrounding said wire, said hair covering forming a core, a fabric cover surrounding the hair core and terminating in flaps, said flaps being stitched together to retain said fabric covering around the insulated hair core and wire and to form a flap portion, said flap portion being flexible to permit of folding upon itself when said body portion is bent around a corner.

Signed at New York, in the county of New York, and State of New York, this 15th day of October, A. D. 1926.
