WIREROPESPLICING TOOL.

Application filed March 9, 1928, Serial'No. 260,461, and in New Zealand January 16, 1928.

This invention has been devised with the object of providing an improved tool for use in the operations of wire rope splicing, as for instance splicing two ends together by the well known inlaying system, and the formation of eye splices upon a rope end. The tool is intended to replace the ordinary marlin spike generally used in the performance of these operations and by its employment greatly facilitates and expedites the carrying out thereof. In effect, the tool is a development of the ordinary marlin spike.

The invention consists in the construction of a marlin spike bar with features of novel nature that provide for the rope strands in inlaying work being quickly and accurately inlaid, and in the combination with the bar of means whereby the rope strands in eye splicing operations may be gripped for tightening and loosened and rolled, as is required in these operations. 1

The tool is illustrated in the accompanying drawings, in which: I

Figure 1 is a plan, and

Figure 2 a side elevation thereof.

Figure 3 is a longitudinal side sectional elevation.

Figure 4 is a cross section on the line 4-4 of Figure 1.

Figure 5 is a cross section on the line 5-5 of Figure 1.

Figure 6 is an enlarged sectional elevation of a portion of the tool.

According hereto the tool is formed by a metal bar 10 of ordinary marlin spike type, that is, with a point 11 at one end, and a cross handle 12 at the other, but in this invention, the bar is made of approximately elliptical form in cross-section so that when the strands of a rope are pierced by the point 11, they may be opened out by turning the bar to cause its major axis to extend across the rope and thereby facilitate the insertion of the jointing strand in ordinaryinlay splicing operations. Such pointed end 11 also is formed with an eye 13 extending through it at an angle in the longitudinal line of the tool. This is for the purpose of threading through the point, the strand of rope to be inlaid, so that then, by winding the tool round and round along on the convolutions of the rope, such strand will be inlaid with the rope strands in the required manner. The point, in addition, is formed with notches 13 in its surface disposed, one on each side of its major diameter, and in line with the said eye 13 so that the rope strands will fit into such notches and keep the tool point in place while it is being wound upon the rope. Also the surface of the point may be grooved with a groove 14 leading to the eye, to aid the laying of the rope strand throughthe eye.

The saidbar 10 also, in this invention, has combined with it, means whereby a strand threaded through the said eye 13 maybe gripped and held, and then released to move through the eye, and afresh grip obtained at another point, in continuous operations, as is required when splicing a strand in eye splicing operations.

These means comprise a lever 15 that is laid Within a groove 16 to extend along the 7 main bar 10 and to project at its back end. The said lever is pivoted at 17 in the bar near its forward end and such forward end passes through aslot opening 18 in the bar and underlies the eye 13 in the bar point.

The lever 15 is adapted to turn on its pivot 17 so that by raising and lowering the back end, the forward end is made to move away from and towards the side of the point 11 into which it is designed to fit, the lever being so fitted into the bar that when turned in, the whole of its forward part lies within the cross-sectional area, allowing of the bar being used in its usual functional operations.

The forward end of the lever 15 is itself formed with aneye'19 that when such end is turned up, makes coincidence with the eye 13 in the point, so as to form one therewith. In the inlay splicing operations beforementioned the strand is threaded through both these eyes 13 and 19, which form one, and in the eye splicing operations the strand may also be threaded through both and the lever 15 worked in and out to slide its end on such strand.

Fitted lengthwise to slide in the lever top is a metal strip 20, the back end of which is connected to a rocking operating lever 21 that is pivoted to the main lever end, and is so designed as by an in and out movement, to push the strip 20 inward and to draw it outward, along within the lever. The said rocking lever 21 is pivoted in bearings 22 upon the end of the lever 15 and extends upwardly. The rear end of the strip 20 passes through this lever 21 and has a stop,

23 upon its extremity so that the desired movements of the strip are obtained through the rocking of the lever. The forward end of this strip 20 extends to the rear edge of the eye 19 in thelever, and is rounded so that when the strip is drawn back, it 0011- forms with the eye, as shown by the full lines in Figure 6, allowing a rope strand to pass freely through it. When the strip is pushed in as in dotted lines in Figure 6, it extends into '3 the eye area and provides for such strand being jambed and gripped between it and the other side of the eye, with a grip that will holldrit tightly while the strand is being .twistedon the main-part'of therope. Then by,- alternately gripping. and releasing the strand, synchronously with working the lever. .endginand out, as shown by the dotted linesin Figures 3 and 6,. the strand may be gripped .and wound in the manner necessary in effecting these operations.

I claim 1. A wire IOPBzSPllClIlQ, tool comprising the combination with a pointed. bar having an eye formed to extend through it near its pointed end, and iformed with a slot extending longitudinallytherein, of a lever pivoted in suchslot'so that it extends longitudinally withzthe barto cause its forward end tolie beneath the said eye, on one side of the pointedlend-ofthe bar, and the rear end to lie along the bar uponits other side, and which lever at such forward end is formed with'anieyeythat is adapted to coincide with the eyeinlthe bar point when the forward-end is "turnedjinward uponthe bar length, substantiallyias specified.

2. In ;a-wire.rop,ej splicing tool constructed in. accordance with claim 1, the combination with the said lever,.of a strip laid along the-outside thereof; and made. movable longitudinally thereon, such strip having its 1forward endarrangedto extend vinto the eye of thelever and its: rear end to project beyond the rear end of the lever, and means upon the lever end whereby the strip may be moved to and fro upon the lever, substantially as specified.

3. In a wire rope splicing tool as claimed in claim 1, the combination with the lever, of a strip arranged along the outside thereof and movable longitudinally thereon, said. strip having its forward end arranged to extend into the eye of the lever and its rear end to project beyond the rear end of the lever, and another lever rockably mounted upon the rear end of the first .mentioned lever and projecting upwardly and through which the rear end of the said strip is loosely passed and held.

41-. In. a wire rope splicing tool as claimed in claim .1, wherein the bar is of elliptical. shape in cross section andis formed with notches on; opposite sides of itspointed end and in line with the eye therein and the slot being shaped to accommodate the lever within the pointed cndand throughout a portion ofthe length ofthe bar adjacent groove-on the opposite side of the bar, substantially as and for the purposes set forth. "In testimony whereof, I affix my signature.
