15 Claims.
This invention relates to an electrical conductor and more particularly to an electrical conductor of the retractile extensible type.
An object of the invention is to provide an efiective and compact retractile cord.
In accordance with oneembodiment of the invention three conductors are enclosed in a braided covering to form a coiled cord, the outer conductor being of greater length than the inner conductors and the tension in the strands form'- ing the braid being so proportioned as to provide a natural twist-in the conductor.
A complete understanding of, the invention may be had by reference to the following description taken in conjunction with the accompanying drawings, in which-- Fig. 1 is a front elevation of a machine for making the conductor of this invention;
Fig. 2? is an enlarged fragmentary sectional plan View taken on the line 22 of Fig. 1;
Fig. 3 is a sectional view taken on line 3-3 of Fig. 2;
' embodying the invention.
Referring now more in detail to the drawings, a braider is shown in Fig. 1 having a frame 6. The braider has a rotating braider head carrying a series of cops I of yarn rotating in a counterclockwise direction and a second series of-cops 9 rotating in a clockwise direction looking at the machine from above.
The details of the mechanism of this machine are more fully disclosed in the patent to Miller, 1,602,442 of October 12, 1926, and will not be described herein.
A plurality of conductors 9, to be covered with braiding, pass upwardly through the braider head. The upper portion H of the braider head is stationary and has a cross piece 12 provided with a Y-shaped fork I 3 and a cut out portion l4 forming triangularly spaced guides for the three conductors. also a guide IS, the guiding portion of which is U-shaped. From the position shown in Figure 2 the conductors and braided covering rotate 90 in a clockwise direction before reaching the capstan I9 and the upper portion of the guide I5 is twisted so as to substantially follow the twist in one of the conductors. The twistthus placed in the cord assists in the helical coiling of the cord. As the yarn i6 is interbraided on the conductors it contacts with two of the conductors but is prevented from contacting the third conductor by the guide i5 until it is close to an axial delivery take-up capstan I9. In passing over the capstan the two inner conductors lie Attached to the cross piece is y .substantially against the outer periphery of the capstan and the third conductor lies radially outwithin the braid. Since the outer of the three conductors is of a greater length than the inner conductors it therefore has a natural tendency to form a helical coil.
This natural tendency of the cord to form a helical coil may be further increased by applying different tensions to the braided yarn. For
instance, in making a helical cord having a right hand pitch the tension on the yarn from the series of cops l, which travel in a counterclockwise direction looking downwardly at the cops in Figure i, may be four ounces on each thread, while the tension on the yarn from the cops 8, which travel in a clockwise direction, may be eight ounces per thread.
A cord made in this manner with the outer conductor of greater length than the inner conductors and the tension on the strands of the braiding greater in one direction than in the other, will form a helical extensible retractile coil without any other elastic materials. In some cases, however, it may be desirable to have elastic materials either as a part of the braided covering or in addition thereto. When using elastic materials as a part of the braided covering, rubber strands or preferably thread covered rubber strands of a type well known in the art may be used on the cops 8 which travel in a clockwise direction and have the higher tension applied thereto when making a retractile coil of right hand pitch. If it is desired to make a coil of left hand pitch the relative tensions in the threads are reversed.
Fig. 6 illustrates a cord in which the threads drawn from the cops 8 are of an elastic matevrial such as rubber.
If it is desired to incorporate elastic material in the coil in addition to the braid, elastic strands ll are passed between tension rolls l8 which are driven at a predetermined speed in relation to the capstan IE! to apply a tension of approximately 180% to the rubber strands. These rubber strands are fed upwardly between the arms of the fork 13 of the cross piece l2 as shown in Figure 2.
It may be desirable in some cases to use an elastic member 2| which passes through the convolutions of the retractile coil and is attached to the ends of the cord by the tips 22. This construction is particularly useful when the cord embodies no other elastic materials and relies for its elasticity on the construction which takes advantage of the inherent elasticity of the conductors and braiding material.
While particular tensions on the yarn and other specific embodiments have been herein disclosed it will be evident that many changes and modifications may be made therein without departing from the spirit'and scope of the invention.
