Description

Feb. 27, 1934. c. L. M cREA ELEGTRICAL CONDUCTOR Filed March 19, 1931 n INVENTOR. (f/20122 5 LZMZ'y-ea BY ATTORNEY Patented Feb. 27, 1934 UNITED STATES PATENT OFFICE 3 Claims.

My invention relates broadly to electrical conductors and more particularly to an arrangement of electrical conductor by which the conductor may be readily secured upon a supporting surface without nailing or otherwise defacing the supporting surface.

One of the objects of my invention is to provide a system of electrical conductors having means for supporting the conductors without nailing or otherwise defacing the surface adjacent which the conductors are supported.

Another object of my invention is to provide an arrangement of retaining means for readily mounting electrical conductors against a supporting surface where the conductors are stretched taut with respect to the supporting surface and positively maintained in position by an adhesive medium adhering both to the supporting surface and to the insulated covering on the electrical conductors.

A further object of my invention is to provide a supporting means for mounting electrical conductors wherein the supporting means possess adhesive characteristics serving to unite the conductors with the supporting surface.

Still another object of my invention is to provide a construction of adhesive tape forming a supporting medium for electrical conductors with means extending transversely of the tape at spaced intervals along the length thereof for supporting the electrical conductors with relation to the tape which is stretched taut and adhesively united with a supporting surface adjacent which the conductors are mounted.

A still further object of my invention is to provide an arrangement of adhesive device adapted to be secured to electrical conductors at spaced intervals along the length thereof for establishing an adhesive connection with a supporting surface and suspending the conductors with respect thereto.

Other and further objects of my invention reside in a method and means for mounting electrical conductors as set forth more fully in the specification hereinafter following by reference to the accompanying drawing, in which:

is a perspective view showing how the tape is used; Fig. 13 is a perspective view showing a modified form of suspension means for electrical conductors according to my invention; Fig. 1a is a side elevation showing still another modifled form of my improved cable supporting units; Fig. 15 is a transverse vertical sectional view of a portion of my improved current cable supporting units; Fig. 16 is a detailed perspective view of one of the units; Fig. 17 is a transverse vertical sectional view showing the adhesive tape attached to an appropriate surface; Fig. 18 is a horizontal sectional view taken on line Ill-18 of Fig. 17; and Fig. 19 is a perspective view showing the adhesive disc and the coacting fastening lugs in juxtaposition.

Referring to the drawing in detail, reference character 1 designates the adhesive tape which extends longitudinally of the electrical conductors and is adapted to be united with a supporting surface on the one side and with the conductors on the opposite side. The tape is provided at intervals with longitudinally extending metallic strips 2 anchored to the tape in any desired manner. As shown in Fig. 2, the strip 2 is perforated at 212 and 2b to provide laterally projecting teeth 20 which extend through the tape 1 and are clinched thereover as represented more clearly in Fig. 3 for retaining the strip 2 in position with respect to the tape 1. The laterally extending strip 2 is constructed from soft pliable metal which is adapted to be bent around the longitudinally extending conductors as represented in Fig. 4 for supporting the conductors. Fig. 4 shows an arrangement of twin conductors 3 insulated from each other by insulation material represented at a and enclosed by an i: .sulated sheathing repre- 106 sented at 5. The insulated sheathing 5 is generally fabric or woven silk whose surface tends to adhere to the adhesive surface of the tape 1. The conductors enclosed in the fabric or woven silk sheathing 5 are first pressed into surface com 110 tact with the longitudinally extending tape 1 for establishing an adhesive connection therewith, the tape being in turn pressed against the supporting surface 6. The laterally extending strip 2 is bent over the insulated sheathing 5 at each end thereof, the bent over ends being directed toward each other as indicated at 2d and 2e.

I have shown in Fig. 5 a roll of the tape having a multiplicity of laterally projecting strips 2 riveted thereto at spaced intervals, which constitutes the completed form of the tape of my invention, which is the form in which the tape is shipped and sold.

In Fig. 6, I have shown in perspective view the manner in which the rear adhesive surface of the tape 1 is caused to adhere to the supporting surface 6. Two of the foldable metal laterally positioned securing means are shown bent around the longitudinally extending conductors while one of the securing means is shown in normal position prior to the bending of the strip around the conductors.

Fig. 7 shows a transverse, vertical sectional view of a modified form of the suspension means of my invention in which two longitudinally disposed lengths of tape are employed back to back as represented at '7 and 8 between which at spaced intervals along the tape, the laterally extending strips 9 are disposed.

As shown in Fig. 8 the strip 9 is secured to the longitudinally extending

tapes

7 and 8 by any suitable means such as rivet 10 which passes through the strips of tape '7 and 8. In order to more completely anchor the laterally extending strips 9 between the lengths of tape '7 and 8, the strip 9 is out-struck to provide securing teeth 9a and 9b which extend in opposite directions and enter the material of the strips of

tape

7 and 8. The out-struck. portions of the strips 9 thus formed serve to prevent twisting or turning of the strips 9 in respect to the tape.

In Fig. 9 I have shown the manner in which the ends of the strip 9 are bent around the conductors in casing 5 as shown at and 9d. Fig. 10 shows more clearly the manner in which the strip 9 embraces the conductors within sheathing 5 at 9:1 and 9b. The appearance of the twin tape construction is shown in perspective view in Fig. This is the form in which the tape is shipped and sold.

Fig. 12 is a perspective view showing the twin tape installed for mounting electrical conductors adjacent a supporting surface. It will be observed that tape 7 directly adheres to the supporting surface 6 while tape 8 directly adheres to the fabric casing 5 of the electrical conductors 3. The bendable strips 9 are shown in two instances as wholly bent around the conductors 4 and in a third instance the strip 9 is shown prior to the bending around the conductors.

In lieu of the longitudinally extending adhesive strips heretofore described, I may employ a series of adhesive pads which serve to support the electrical conductors at a. series of different positions along the length thereof as shown in perspective view in Fig. 13. In this view the conductors which are encased in the fabric covering 5 are supported by adhesive pads 11 which are engaged with the supporting surface at spaced intervals along the conductor 5.

In Fig. 14, I have shown the adhesive pad 11 as being provided with a diametrically extending strip 12. As shown in Fig. 15 the strip 12 is attached to the pad 11 by means of outstruck projecting lugs 14 which enter the material of the adhesive pad 11 and are anchored therein and clinched thereover. The lugs 14 are punched directly from the strip 12 leaving apertures 14a in the strip 12 as indicated in Fig. 16. The diametrically extending strip 12 has portions which project beyond the limits of the adhesive pad 11 and are bent over the encased conductor 5 as shown at 12a and 12b for maintaining the conductor i position.

As shown more clearly in Fig. 18, the adhesive pad 11 serves as a mounting means for the conductor 5 at selected intervals along .the supporting surface 6. Fig. 19 illustrates the manner in which the lugs 14 pierce the adhesive pad 11 and are secured thereto. In the shipment of adhesive supports of the construction illustrated in Fig. 19 the supports may be stacked one over another as distinguished from the rolled tape construction illustrated in Fig. 5.

I have found the mounting means for conductors as shown herein highly practical and while I have described preferred embodiments of my invention, I desire that modifications may be made and that no limitations upon my invention are intended other than are imposed by the scope of the appended claims.

What I claim as new and desire to secure by Letters Patent of the United States is as follows:
