E COUPLING;

Application filed March 2, 132,8. Serial Kilo. 258,619.

This invention relates to i nprcveinents in toggles for ropes, cables and the like.

In the use o1 simple toggles, the rope or cable which is looped around the center oi? the toggle receives the loop of the detachable rope or cable in suchmanner that the detachable loop of the rope or cable isconstantly chafing andv cutting into the rope or cable which is secured aroui'ul the center of the toggle. To prevent this chafing and cutting 01 the ropes or cables, it is common practice to serve the said loops with a tough twine. This practice offers a temporary protection, but is by no means permanent, as upon the chafing and cutting of the serving, the loops become exposed at the contacting points of the two loops.

This invention has for its 'irincipal object, the construction of a toggle enil'xulying a thiinble element so arranged with relation to the toggle proper, as to insulate and separate the two loops of the ropes, cables or the like to ell'ectually and permanently pre vent the chafing or cutting of the said loops.

The invention is hereinafter more fully described in connection with the accompanying drawings. Objects of a more specific nature will become apparent in the description and the essential characteristics are sunnnarized in the claims.

In the drawings:

Figure l is a front view of the coupling with cables connected thereto;

Figure 2 is a rear View of the same;

Figures 3 and 41- are front and rear views respectively of the coupling per so; and

Figure 5 is a central vertical section through the coupling with the positions of the cables indicated in broken lines.

The toggh: is very simple in construction and consists of a casting or forging niachined so as to forrn oppositely projecting members oil the toggle proper and. central grooved part 11, a depending shield-like or thiinble portion 12 and a transverse hole The members 10 may be provided with arcuate grooves '14: on their undersides and the shield or tliiinble 12 is formed on its front face with a concave transverse surface The detachable cable 16 is looped so as to receive the members 10 oil the toggle proper and he longitudinally oi the'structure 1n the grooves 14 and upon the su ce of the t nole pm is; term i? cable being spliced and served above the toggle as indi ed at 17. The nien'ibers 1O andsurlace l5 thus act as a thinible for the terminal loop of the detai'zhablc cable 16. f i

The rear face of the shield 12 is formed with al grooved or recessed surface 18. The stationary cable 19 is passed over. the grooved part 11, through hole 13 and over the recessed iace l8, and lies transversely of the structure where the terminal thereof is spliced to the main strandsat 23. The red face 18 is curved leading to the hole 13 so that the cable is not subjected to sharp corners but is subjected to easy bends. The loop of cable 16 also passes over roiuidcd surfaces formed by the grooves 14 and concave surface 15 of the thiinblc portionl2 and in like manner is not subjected to sharp corners.

, The toggle illustrated and described herein causes the strain on the cables to be properly" distributed preventing undue distortion oi the strancs, and effectually separates or insulates the two loops 16 and 19, lying at right angles to each other while at the same time, the loop 16 is as quickly and readily detachable as in the use of simple toggles.

It will be noted that the embodiment of the thin'ible member, which connects with toggle ineinber proper at points on each side of the center of the latter stifiens and strengthens the toggle member proper and renders the same better capable of withstanding the sudden and heavy strains to which devices of this class are, constantly subjected. I claiin':

1. A-cable toggle comprising a unitary structure having oppositely projecting menibcrs adapted to receive tre vsverscly of the toggle the loop of a cable, a'shield dependfrom said HIOHLlJGI'S and adapted to re- 0 v, longitudiinally oi. the toggle the loop oi: a cable, the said shield lying between the contiguous surfaces of the two loops of the cables to separate the same and prevent chaling ol: one loop on the other.

2. A cable toggle including oppositely proectzng inieinbers adapted to receive trans- 'versely oi the structure the loop of a cable,

and adapted to receive longitudinally of the structure the loop of a cable, and a shield c, "en a g from the opposite y projecting and adapted to lie he the tiguous surfaces of the loops of the cables to separate the same and prevent cha'nng of one loop onthe other.

through and transverse and longitudinal rounded surfaces for contacting respectively with said loops. a V

.4; A cable toggle includin oppos tely projecting members adapted to receive transversely of the structure tholoop of a cable, and a shield connecting the oppositely proeoting members and adapted to straddle the'said loop of a cable, the said shield extending from the oppositely projecting members to receive in connection with said members, the loop of a cable longitudinally of the structure, the Whole arranged in such manner that the said shield lies between the contiguous surfaces of the two loops the cables to prevent chafing of one loop on the other.

5. A cable toggle adapted to receive the loops of two cables, one loop transversely of the structure and therother loop. longitudinally of he structure so that the two loops lie at rightangles' to each other and means on the toggle for separating the contiguous surfaces otthe two loops to prevent chafing of one loop on the other.

In testimony whereof I aifix my signature.
