In France 2 Claims.
This invention relates to an extensible device or elastic cord of the type comprising an endless core of elastic material and a longitudinal sheath of textile or similar material, in which the two strands of the elastic core are pressed together, said sheath being constructed in such manner as not to interfere with the stretching of the core.
The present invention has for its object an extensible device of the aforesaid type, in which the parts of the elastic core, which are in contact with the attaching members provided at the ends of the extensible device are enclosed in an aux iliary sheath of cloth or like material, whose purpose is to protect the elastic core against deterioration and wear at the place where it bears upon the attaching members. Said auxiliary sheaths are preferably placed upon the core while the latter is under tension and their ends are covered by the longitudinal sheath in which the two strands of the core are enclosed.
In the accompanying drawing, which is given by way of example:
Fig. 1 is an outer view, partly in section, of an extensible device constructed in accordance with the invention;
Fig, 2 is a perspective view of one end of the device showing a further arrangement of the attaching member;
Figure 3 is a side View, partly in section, of a further construction of the extensible device according to the invention;
Figure 4 is a detail view of one end of the device; shown in section, according to the line 1 -4, Figure 3.
. In the example of execution shown in Figure 1, the extensible device comprises an endless core or loop l of elastic thread, either bare or covered, and an outer sheath 2, in which the two sides or strands of the endless core are pressed together. The elastic core l can be obtained either by winding a continuous thread or by placing together a plurality of loops, or also by using a single loop of suitable cross section. The sheath 2 is applied upon the elastic core while the latter is held under tension, whereby said sheath will not interfere later on with the stretching of the elastic core when the latter is subjected to a longitudinal traction. The sheath can be made of any desired textile material (cotton, flax, hemp, natural or It may be either woven, knitted or braided. The sheath could also be made of an elastic material such as rubber or an elastic or other ribbon wound helically. The elastic core is preferably covered at the ends of ythe device by two auxiliary sheaths 3, which are June 3, 1930 placed while the core is under tension. The ends of said Auxiliary sheaths are covered by the longitudinal sheath 2.
The auxiliary sheaths 3 can be constituted either by pieces of cloth or other material closed by a longitudinal seam or woven, knitted or braided coverings, or again by elastic or other tapes, wound helically around the core. They may also be formed in any other suitable manner.
The attaching members are passed through the ends of the elongated loop formed by the elastic core. As shown in Figure l, each of the attaching members may be constituted by a hook 4, having a threaded shank 5 screwed to a sleeve 6 and held in place by a clamping nut 8. On the sleeve 6 is pivoted a hook 7, optionally double, a Carbine hook or any other suitable attaching device. By screwing or unscrewing the hooks, it is possible to adjust accurately the distance between the same.
When said distance is subject to a certain allowance, the hook '7 or like attaching means may be inserted directly through the loop of the elastic cord (Figure 2) during or after the manufacture.
The manufacture of the extensible device according to the invention comprises several steps. In the first operation, the endless core is manufactured either under tension or not. Next, the said core being subjected to a suitable tension, the auxiliary sheaths 3 are put into place and finally the core is covered with the longitudinal sheath 2. The last operation is performed on a weaving, knitting, braiding or any other suitable machine.
The winding of the core is preferably effected under tension, so that the core can be transferred directly from the winding machine to the machine used for manufacturing the sheath 2.
Figs. 3 and 4 show that auxiliary protecting sheaths may also be provided on extensible devices of a type already known wherein the attaching members are constituted by thimbles or pulleys disposed in the' end portions of the oblong loop which forms the elastic core of the extensible device.
As in the rst embodiment above described; said auxiliary sheaths will cover and protect the end portions of the elastic core or loop.
It will be seen in Fig. 3 that the hooks 4 of the first embodiment are substituted by thimbles or pulleys 104 disposed in the end portions of the elastic core or loop 101. The auxiliary sheaths 103, similar to those above described, enclose the parts of the elastic core which are in contact core made of elastic thread and forming a hank, l
attaching members at the ends of said hank, auX- iliary sheaths enclosing the portions of the core in contact with said attaching members and a longitudinally expansible and contractible sheath enclosing loosely both strands of said hank together over the entire por-tion thereof between said attaching members.
2. An extensible device comprising an endless core made of elastic thread and forming a hank, attaching members at the ends of said bank, auxiliary sheaths enclosing the portions of the core in contact with said attaching members and a longitudinally expansible and contractible sheath enclosing loosely both strands of said hank together over the entire portion thereof between said attaching members and covering the ends of said auxiliary sheaths.
