(c1. 294-74) This invention relates to a rope fitting of the thimble ywhich is provided in its .exterior with av type generally called a thimble. In the pargroove 2 of, such .size 'as .to .receive the ropes with ticular-forms shown, the thimble forms a part which the thimble is to be used.

In the modiiied form of Figure 10, the thimble la is provided with a groove 'as in the case of the other forms, and is provided on each side with a perforation 24 of suicient size to allow the rope section Illa to pass throughit-Without being caught or cramped. Adjacent its lower end, the

thimble is provided on each side with a projec- .tion,25.about which the rope, ends vI Ia and I2a may be wrapped, the rope end being arranged so that it passes over itself and is gripped as .shown by a J-bolt 26, which is secured by a nut v2l. The projection 25 may be omitted or used if desired. It is convenient to use it on relatively large sizes of rope or cable and it is notv necessary on smallerA sizes. On smaller` sizes, the rope ends are merely twisted about the shank On larger sizes where it is 25 is an added convenience. A

.In the forms shown in Figures 12 and 13, the Vthimble is generallythe same as that shown in Figures 10 and 11, as in that form the thimble is provided with perforations or passages 24h vthrough which the rope section Illb may pass and the rope ends IIb and I2b are received in grooves or depressions 2lb Which may be formed .inthe exterior of the thimble and are held in place therein by U-bolts 28 which areY secured by nuts 29. The grooves 21 may be angularly disposed with respect to the groove 2 as shown in Figure 13, or they may be otherwise arranged.

,I We claim:

1. In combination in a rope thimble, a member dening an eye and having a grooved exterior, and a rope having apair of rope ends, each being passed oncev about said eye and having its free end secured to said eye defining member `and a pivoted hook pivoted on and depending from said .eye defining member,`said .rope being free at all points away from said thimble and adapted to engage said hook.

2. In combination in a rope thimble, a member defining an eye and having a grooved exterior, and a rope having a pair of rope ends, each beingl passed once about said eye and having its free end secured to said eye defining member, and being elsewhere in contact with but free to move with respect to said eye and a pivoted hook pivoted on and depending from said eye defining member, positioned between said rope ends.

3. In combination a sling and thimble, said thimble comprising a member forming an eye,

`there being a plurality of sockets formed in said eye forming member, said sling having two ends, each end being passed once about said eye formingmember, once through one of said sockets and into the otherhof said sockets, and a Wedge located within each of said sockets and in contact with one of said slingv ends, whereby the sling end is lsecured in one of said sockets.

4. In combination a sling and thimble, said thimble comprising a member forming an eye, there being a plurality of symmetrically arranged sockets formed in said eye forming member, said sling having two ends, each end being passed once about said eye forming member, once through one of said sockets and into the other of said sockets and being rebent into said socket, Vand a wedge located within each of said sockets and within the bend of said sling endand in contact with one of said sling ends, whereby the sling end is secured in. said socket.

5. In combination in a sling, an exteriorly grooved eye-forming member, a rope sling associated therewith, said rope sling having two ends, a pair of sockets formed one on each side of said eye-forming member, both rope ends extending into each socket, one rope end being positioned freely therein for movement therethrough, the other being reversed upon itself, one reversed portion lying partially within each said socket, and means for securingeach reversed portion Within the socket in which it lies.

6. In combination in a sling, an eye-forming rope thimble having an exterior groove and a pair of sockets positioned one on each side of said eyeforming member, each socket providing a clearance, a rope end positioned within said clearance for free movement therethrough, a second rope end extending into said socket and being bent upon itself Within said socket, and means for securing it in position in said socket.
