SCHEMMEL, OF UNION CITY, INDIANA ORNAMENTAL CONDUCTOR FOR ELECTRIC WIRES Original No. 1,713,302, dated May 14-, 1929, Serial No. 288,747, filed June 27,, 1928. Application for reissue flledlanuary 13, 1930. Serial No. 420,617.

My invention relates to the insulation of electricwires, but has reference more particularly to an ornamental conduit or container for such wires which would otherwise be exposed to view and more or less unsightly.

Of course when electric wires are concealed within the walls, floors or partitions of dwellings, office buildings or other structures, there is no particular object in locat 1o ing them in an ornamental container, but when used in surface wiring the matter of appearance becomes one of importance, as does also the means of securing such containers in operative position, as, for example,

' 15 when installing signal bells or radio connections in an old or completed building.

An object of the present invention is, therefore, the production of conduits for wires which are not only highly ornamental, but

which are at the same time quickly and securely fastened to washboards, door frames, window frames and the interior trim generally.

Wires of the character indicated, when of surface application, are sometimes twisted together into a two-strand cable and fastened in position by means of tacks passed between said twisted strands, and, of course, clear of the wires themselves. At other times the Wires are merely stapled into operative position, or are arranged in parallelism, being then bound together and t0 the supporting framework by suit-able brackets, but usually such fastening means are exposed to view and sometimes are very unsightly.

As a further object. the present invention contemplates and provides ornamental and efiicient means for concealing and insulating electric wires, and at the same time means for concealing the fastening means whereby the conduit itself is held in operative position.

A further object of this invention is the production of means whereby electric conducting wires are enclosed within independent floating tubular jackets, the latter in turn each being united, along one longitudinal side line only, to an attaching base portion by which the completed structure may be secured in operative position.

In the accompanying drawings which form part. of this ap lication for Letters Patent and whereon li e numerals indicate correspondlng parts in the several views:

Figure 1 is a perspective view showing one corner of the interior of a room, a washboard and part of a door frame, with a section of the improved wire conductor adjacent to said washboard and door frame in position for use;

Fig. 2 is also a perspective view on a relatively enlarged scale showing one form of the present ornamental conductor insulator with insulated wires projecting somewhat from one end thereof;

Fig. 3 is a view of the invention similar to Fig. 2 except that the container has been here temporarily deformed or spread at its cenitral portion to admit a fastening tack; an

Fig. 4 is an end view of the invention showing one concealed securing tack driven through the body of the conductor and into the supporting trim.

Reference being had to the drawings and numerals thereon, the conduit is formed of a covering fabric of leather, leatherized cloth or any material which is characterized by suitable flexibility. The covering material may be of any color or combination of colors and provided with any desired surface ornamentation to harmonize with the woodwork or trim of the room in which it is to be located, or with the interior hangings or furnishings of the room.

The covering fabric is folded upon itself to provide a base portion 1, reinforced and stiffened, if desired, by the inclusion of a filler strip 2, and, in the embodiment of my invention illustrated by the accompanying drawings, terminating above in two parallel contacting centrally positioned rolls or tubular'beads 3, 3. In these beads are located the independent electric wires 4, 4, which in turn may be further insulated and spaced apart by agenc of a non-conducting filler, such for examp e, as the rubber tubing 5 and a surrounding covering 6 of silk or the like.

Since the sole function of the wires 4 is to carry an electric current, it is obvious that 16D these wires will in practice be formed of a material of highelectrical conductivity. As is well known in the art, copper and its alloys constitute at the present time the most 'efiicient known commercial conducting ma.-

terials, and accordingly I prefer to provide wires 4 ,of copper-- or its alloys.

Except for those portions of the device which contain the conducting wires and conceal the tack receiving portion of the base, as will presently be described, the conduit as a whole is of substantially flat or tape-like form. Bothvplies of the base portion 1, as also the filler strip 2, are firmly securedtogether by lines of stitches 7, 7, each arranged and positioned just outside of its respective bead portion 3 so that the lattermay be forcibly lifted from the base portion, as shown by F1 3,-to permit introduction of fastening tac 8 as the means of attachment. Each bead 3' is capable of automatically returning to normal position, as shown by Figures. 1, 2 and 4, when the spreadin stress is removed, thus closing over the bee s'of tacks 8 to hide them from view, which is known as blindnailing.

Having thus described my present invention, its use, operation and advantages are quite obvious, but may be briefly stated as follows: y

The present form of universally flexible conduit, having been constructed and arranged substantially'as shown and described, efliclently insures the proper spacing at all times, and insulation ofthe conductor wires 4, 4, permanently located therein, and may be quickl neatly and effectually applied to baseboar s, door frames, or other trim elements, as indicated in Fig. 1 of the drawings,

lit!

by the simple process of liftin the tack concealing beads 3 away from the%ase portion 1, and applying tacks 8 atsuitable intervals, as shown. This accomplished, the said beads automatically close down over the tack heads to conceal them, whereupon the fastening is com lete.

T a structure shown and described hereinabove constitutesbut one'exemplifica'tion of my, present invention, and Ido' not desire to be limited to the specific details of construction embodied therein. On the contrary, va-

rious modifications to meetyvarying conditions and requirements will suggest themselves to persons familiar with the art to which my invention relates, and these modi-c fications are to be considered within the s irit of my invention and covered by.the

c aims appended hereto. ,For example, it is not always necessary ordesirable to use two electric conducting'wires, a single wirebeing sufiicient for some purposes, as in the case of the connection between a radio receiving set and its antenna,.or its ground. For such use only one of the-beads need contain an electric conducting wire. The other bead is .then

preferably not left empty, but may inclose any suitable filler, as, for example, twisted paper or cotton cord.

Again, it will be noted that the specific form of covering which I have illustrated in the accompanying drawings and described herein is similar to the structure known to the automobile body trimming trade as Hidem welt, which forms the subject'of United States Letters Patent No. 1,226,600, granted to me May 15, 1917. I haveshown and described Hidem welt as forming one element of my present invention merely because the combination of electric conducting wires with Hidem' welt constitutes the best mode in which I have contemplated appl ing the principle of my present invention. t is to be understood, however, that an of the various types of relatively flat bind-nail finishing welts now available, or indeed which may be hereafter devised, may be used as the covering element of my present invention, the essence of which is the combination of electric conducting means with blind-nail ornamental covering therefor.

Having thus described my present inven tion, what I now claim' and desire to secure by Letters'Patent is:
