Description
Patented Feb. 6, 1940 rATENT oFFicE ROPE THIMBLE Earle J. Mardis, Chicago, Ill.
March 24,
13 Claims.
' This invention relates to a thimble for wire rope'and, more particularly, to an improved rope thimble that will insure equal loading on each of the strands of the rope.
Various types of rope clamps or thimbles have been suggested and vcommercially used. Most of these types, especially that commonly known as the wedge socket type have not proved very successful in that the wedge produces a greater bearing force against one or more strands of the rope, `which results in a greater portion of the load being carried by those strands. Such a condition causes an unbalanced loadv on the strands of the ropev which is, of course, very undesirable.
It is an object of this invention to provide an improved rope thimble whichwill bear equally on each of the strands of the rope.
It is another object of this invention to provide a rope thimble which will securely hold the extreme dead end of the rope while the looped adjacent portion toward the live end thereof is threaded and properly placed under tension in the thimble clamp. y
. Various other objects'and advantages of my invention will more fully appear during the course ofthe following specification and will be particularly pointed out in the appended claims.
In the accompanying drawing, kI have shown, for the purpose of illustration, one preferred embodiment and a slight modification thereof which my invention may assumein practice.
In the drawing: l.
Figure 1 is a side elevation, showing the improved rope thimble of the preferredformof my invention assembled on 'the end of a rope;
Figure 2 is a plan thereof;
Figure 3 is a sectional view taken on the line III-III of Figure 2;
Figure 4 is a plan view similar to Figure 2 show- Application ing a slightly modi'ed construction of the rope thimble of my invention; and,
vFigure 5 is a sectional view taken on the line vV-V of Figure 4. l
Referring more particularly to the drawing, the v preferred embodiment of the improved rope thimble of my invention, as shown in Figures 1, 2 and 3, comprises a plate-like member 2 having a thin body portion 3 diverging outwardly into a thickened semi-circular shaped outer end portion 4 having a groove 5 arranged in the edge around the periphery thereof.
There is provided a co-acting plate-like membe'r 6 of substantially the same thickness as the thin body portion 3 of the plate-like member 2 which is adapted to abut against the inner edge 1939, serial No. 264,045
of the thickened portion 4 thereof. The platelike member 2 has grovoes l 'and'la on the inner surface thereof which correspond with grooves 3 and 8a, respectively, on the inner surfaceof the plate-like member 6 and are adapted to lreceive af rope 9. The corresponding grooves l and 8 on the side of the thimble adapted to hold the live end of the rope have preferably a smooth surface while the correspondinggrooves Ia and 8a on that side of the thimble adapted to hold the rope toward the dead end thereof are preferably corrugated or otherwise provided with suitable means for gripping the same.v The plate-like member is held in co-acting relationship with the plate '2, preferably by means of machine screws or suitable bolts III placed along the edges and in the center thereof and it will be understood that the two plate-like members are adapted to hold the rope therebetween toward the live end thereof. 'The inner edge of the plate-like member 6 is preferably cut away as at I2 so as to receive a substantially rectangularly shaped segmental plate-like member I3. This segmental member I3 preferably has a corrugated groove `I4 arranged on the inner surface thereof and is adapted tol. co-act with the plate-'like member 2 to securely hold and clamp the extreme end o-f the dead end of the rope, preferably by means of machine screws I5 placed on each side thereof.
'I'he thickened end portion 4 has preferably a 30 hole I6 arranged therein, for thimble attachment purposes, and is positioned preferably in align ment with the live end of the rope. This hole I6 is preferably lined by meansof a suitable removable bushing member I1.
InFigures 4 and 5 there is shown a slight modication of the improved rope thimble of the present invention. This modified construction is rsimilar to the preferred construction but instead of using a segmental plate-like member I3 in the :40 inner cut-away edge portion at I2 of the co-acting plate-like member 6, a pair of U-bolts I3 are l provided for co-acting with the plate-like member E for holding the rope toward the dead end thereof. It jwill be understood, of course, that .45 vany other suitable `bolts or means may be provided 'for co-acting with the plate-like member 2 to Vhold'tlieend. of the rope toward the' dead end thereof in place of the segmental member I3 or 'the Ubolts I8. In this construction the50 co-acting plate-like member E preferably has arranged therewith an outer extending lug portion I9 which is adapted to extend to one side of the live end of the rope into the eut-away portion at I2 so as to provide a means for receiving 2111,55
additional machine screw or clamping bolt 20, as is clearly shown in Figure 4; of the drawings.
As a result of my invention, it will be seen that there is provided a relatively thin and iiat rope thimble, and that the dead end of the rope can be securely clamped in position by means of the segmental clamp I3 or U-bolts i8 and the adjacent portion oi the rope toward the live end thereof threaded or looped under tension between the plate-like members 5 and and securely clamped therebetween without any damage thereto. It will also be seen that the rope thimble of this invention `is clamped securely over substantially the entire loop of the rope, thereby eliminating the danger o any slippage or distortion whatsoever of any of the strands or ,that part of the rope looped around the thimble.
The present application is a continuation-inpart oi applicants copending application, Serial No. 202,347, nled April l5, 1938.
While I have, in this application, specincally shown and described one embodiment and a modification thereof which my invention may assume in practice, it will be understood that this embodiment is merely for the purpose of illustratien and description and that various other forms may be devised within the scope of my invention, as defined by the appended claims.
