11 Claims.'

This invention relates to a fairlead or the like, although the invention in its broader aspects may be embodied in other devices.

An object of the invention is the provision of an improved fairlead including cooperating parts constructed and arranged to facilitate convenient relative assembly and disassembly of the fairlead. and cable or like element to be supported or guided thereby and to facilitate detachable connection of the fairlead to afsupport.

Another object of the invention is to provide animproved fairlead which is adapted to be directly assembled on and disassembled from a cable, wire or the like, at a location intermediate the ends thereof.

A further object of the invention isi to vprovide a resiliently yieldable connection between the respective parts of a fairlead of this character which serves to retain the parts thereof permanently united together and so oriented with respect to each other as to obstruct displacement thereof from a cable, wire or the like, and which in addition'serves to accommodate snap-on attachment of the fairlead to a supporting structure and to resiliently urge the respective parts of the fairlead into interlocked engagement with the supporting structure. 4

A still further object of the invention is to provide a connection between the parts of a fairlead of this kind which comprises rubber-like material surface bonded to such parts.

More particularly, an object of the invention is the provision of a fairlead having a passage therethrough for receiving an element to be guided or supported and including parts having a resiliently yieldable connection therebetween which permits relative movement thereoi between positions respectively accommodating insertion of the elementinto the fairlead passage and obstructing removal therefrom, and which also permits such relative movement of the parts for connection of the fairlead to a support therefor;

Another object of the invention is the provision of a simple and economical unitary construction having a minimum number of parts and so connected together as to readily permit attaclfunent` of the fairlead to a support.

Other objects and advantages of the invention will be more apparent from the following de-` scriptiontaken in connection with the accompanying drawing in which:

I'EDOSE.

Fig. Zis a plan view showing the fairlead extended.

Fig. 3 is a side view of the fairlead in its Fig. 2 position.

Fig. 4 is a view similar to Fig. 1 showing the iairlead` engaged with a support.

Figs. 5, 6, and 7 are fragmentary perspective views illustrating` the assembly of the fairlead with respect to a cable and support.

Fig. 8 is a side elevation of a modified form of the invention, the iairlead being shown in repose and with a cable therein.

Fig. 9 is a plan view of the Fig. 8 showing.

Fig. 10 is a view similar to Fig. 9 but showing the relative position of the parts when the fairlead` is attached to a support.

Fig. 1l is a side elevation showing the fairlead attached to a support.

Fig. l2 is a plan view showing the iairlead compressed to its smallest size preparatory to attachment to a support.

The invention is illustrated and described in a fairlead A which, in the embodiment illustrated in Figs. 1 to 7, inclusive, includes a pair of block-like members I5 each of which may be of any suitable material but preferably one having good abrasion resistant properties. Each member has an opening I6 therethrough cooperating one with the other to form a passage through the fairlead, each such opening being somewhat elongated in the direction of the length of its member. lip I'I formed by elongation of the opening extends overa portion of the latter and is spaced from the opposed wall of its associated opening I6 to provide an accessv slot I8 communicating with the latter. The members I5 are connected and retained in assembled relation by two bodies I9 oi rubber-like material bonded to adjacent surfaces, each such body I9 being disposed between adjacent shoulders 20 and 2| respectivelyl formed on the members I5.

-f with the access slot I8 of the other.

free from stress and insertion of an element into` or displacement from the passage is prevented.l By relatively moving the members I5 lengthwise and in a direction to elongate the fairlead against the resistance of the rubber-like material, the

members I5 are brought to aposition wherein the access slots I8 are in registry as shown in Fig. 2 and insertion of an element into or displacement from the passage is accommodated. Any tendency of the members I to bind or crimp the element in the passage-forming openings I6 incident to the aforesaid relative movement is obviated by the elongation of these openings.

Referring to Fig. 4, the members I5 have been relatively moved lengthwise from their Fig.` l position, in a direction opposite from the direction of movement to the Fig. 2 position, which movement is yieldably opposed by the rubber-like material acting both in shear and compression. Movement to the Fig. 4 position thus reduces the length of the fair-lead and permits snapping the same into engagement with a support 22 therefor, as more particularly shown and described in connection with Figs. 5, 6, and '7. Each member I5 has a groove 23 at one end thereof for receiving an edge of the support.

Referring to Figs. 5, 6, and 7, the fairlead A is shown in process'of assembly with respect to the support 22 with respect to which a cable 24 is guided and supported thereby. The support 22 may be a bulkhead or the like and has an opening 25 through which the cable 24 passes. In Fig. 5, the fairlead is shown in repose, as in Fig. l, and in Fig. 6 the fairlead has been disposed in a position corresponding to that of Fig. 2 for reception of the cable 24, as seen in Fig. 7 wherein an edge of the support bounding the opening has been disposed in a groove 23 preparatory to compressing the fairlead in order to snap the opposite edge of the support into the other groove 23. This snap action is facilitated by the arcuate-like taper of the end of the member I5 adjacent the groove 23. Thus, by pressing the free end of the fairlead shown in Fig. 7, the members I5 are relatively shifted against the opposition of the rubber-like material sufliciently to engage the free groove with the adjacent edge of the opening 25 with the material of the bodies I 9 under load as set forth in connection with Fig. 4.

Referring to the embodiment of Figs. 8 to 12, inclusive, the fairlead A' includes two generally annular wedge-shaped members VI 5 each having a groove 23 in the enlarged portion thereof and a slot 2G extending inwardly from the periphery thereof. The inner end portion 2'I of each slot is angled from the main portion 28 and in the assembly the angled portions extend in opposite directions as shown in Figs. 9 and 10. The portions 2`I constitute a passage receiving the cable 24 while the main bodies 2B constitute an access slot. A body of rubber-like material 29 is bonded to and connects the members I5 for relative movement as will hereinafter appear.

In Figs. 8 and 9 the fairlead is shown in repose, in which position the members I5 are relatively offset, the material 29 is substantially free of stress, and the access slots, constituted by the portions 28, are in registry one with the other to accommodate insertion of the cable 24 into the passage provided by the slot portions 21. In order to secure the fairlead A to the support 22, the members` I 5 are relatively rotated against the resistance of the material to the Fig. 12 position wherein the access slot portions are out of registry and the members I5 are in substantial registry. In this position the fairlead is compressed to its smallest size for insertion in the opening 25 with the bounding edges thereof engaged in the grooves 23 as shown in Fig. l1. The fairlead expands from the Fig. 12 position to the Fig. position when so engaged with the support, it being understood that the material 29 is under load and tends to urge the members I5' to their Fig. 9 position thus urging the members I5 into engagement with the support.

In this embodiment the fairlead is in repose conditioned to receive the cable as the slots 28 are in registry and but a single operation or movement is necessary in order to assemble the fairlead relative to the cable and support. The wedge shape of the members I5 makes possible alignment of the grooves 23 for respectively receiving oppositely aligned edges of the support.

Where the cable or other element is adapted to slide or rotate relative to the iairlead the members I5, I5 preferably comprise a good abrasive resistant material.

Although but several specific embodiments of the invention are herein shown and described, it will be understood that various changes in the sequence of operationssteps and materials employed may be made without departing from the spirit of the invention.
