MOLDING FOR ELECTRIC WIRES Filed June 21, 1935 2 Inventor.-

Mdilejebvre Patented July 20, 1937 UNITED STATES PATENT OFFICE Application June 21, In France Claims.

The present invention relates to moldings, preferably metallic moldings, in which the wires are arranged in a base secured to the supporting wall and are eventually maintained in place by 5 convenient devices bearing upon the base, the cover of such moldings being removably secured to the base.

The present invention; consists in bending, inwardly the edges of the base, preferably according a U-shaped section.

Another feature of the invention also consists in using such overturned edges as a fulcrum for the devices intended to maintain in place the wires and eventually for the cover.

By way of example, in the accompanying draw- Figure 1 is a view in perspective of a molding section according to the present invention.

Figure 2 is a transverse section of such molding.

Figures 3 and 4 are modifications of the molding according to the present invention.

The molding shown in Figures 1 and 2 is formed by a base I, in which are arranged the electric wires 2, and by a cover 3.

The lateral edges of the base I are inwardly bent at 4 so as to form an inverted U. Each part 4 forms a slide bar for the wire fasteners 5 and at the same time maintains in place the cover 3 owing to a yielding pressure which is thus exerted upon the projecting edges 6, which are located at a distance which is slightly higher than the spacing of the bent parts 4 in their position of rest.

The wire fasteners 5 are constituted by spring steel bands in the form of an unsymmetrical S and may be arranged at the desired places, one of the ends being insertable in the slide bar formed by the bent part 4 of the base I. On the other hand, wires 2 of diiferent sizes may be maintained in place, owing to the different curvatures of the wire-fasteners 5, which enable them to be subjected to widely varying deformations.

The molding shown in Figure 3 is similar to the embodiment shown in Figures 1 and 2, but in this 1935, Serial No. 27,784 July 7, 1934 case, the wire fastener 5 which is also formed by a spring steel band, is secured to and bears against a stop III which is maintained in place by the bent edges 4 of the base I.

The molding shown in Figure 4 resembles the molding shown in Figure 3 in the general form of the wire fastener 5. But in this case, the wire fastener 5 directly bears against the bent edges 4 of the base I.

As it will be seen, in all such types of moldings, the wire fasteners 5 may be arranged at the most convenient places, they can indeed be moved in the slide bars formed by the bent edges 4 of the base I.

Having now particularly described and ascertained the nature of my invention and in what manner the same is to be performed, I declare that what I claim is:

1. A conduit for electrical conductors adapted to be attached to a support, comprising a mold? ig in two sections, a channel-shaped base for reception of said conductors, a cover member closing said base and bearing thereon; means for attaching the base of said molding to a support, a plurality of resilient inserts, each of said inserts having at least one end bearing against an upper edge of a side wall of said base and an end exerting pressure toward the bottom of the channel'in said base, said inserts serving to force said conductors against the bottom of said base by bearing against the upper surfaces of said conductors.

2. A molding according to claim 1, wherein the longitudinal edges of the base are bent inwardly.

3. A molding according to claim 1, wherein the longitudinal edges of the base are bent inwardly and the inserts bear against said bent edges.

4. A mold according to claim 1, wherein the insert consists of spring blades.

5. A mold according to claim 1, wherein the insert consists of spring blades substantially in the form of the letter S, the loops of which are unequal.
