I accomplish these and other objects and obtain my/new results as will be apparent from the device/ described in the following description, particularly pointed out in the attached claims, and illustrated in the accompanying drawing, in

Figs. 8 and 9 are marks of some gripping means employed in the invention.
Referring more particularly to the drawing,
Y reference numeral I0 of Figs. 1, 2 and 3, indicates the tubular envelope, with each end tapered as at II, I2, I3 and I4, the gripping jaws, respectively, located in each tapered end; I5, the coiled spring, holding the sets of jaws apart; I6, a cap for enclosing the end of the spring; I1, the spider for holding the jaws in spaced relationship to each other; and I8, the conductor, inserted in the open end I9 of the splicer.
The invention, in these figures, is shown incorporated in the spider, or cap I1, which consists of a body or end section 28, having extending fingers 2|, 22vand 23, each aperturedas at 24, 25 and 26, in the form shown, to receive the rivet head 21, 28 and 29, shown as integral with the Jaws. obtained by cut-outs 30, 3| and 32, forming a Y as seen from the view shown in Fig. 3, which cutouts terminate in tongues 33, 34 and 35, in extending ngers 2l, 22 and 23, respectively.
'I'hus each extending finger is made more exible by forming the tongue therein, leaving side walls 36 and 31, in the case of finger 22, up to the end seated on the jaw I3 where the aperture 25 is formed.
This exibility is desirable where surface irregularities in the inside of the shell cause the jaws to assume slightly changed longitudinal positions, or where it is desired to grip various sized conductors.
supported by end sections 38 and 39; nger 23,
by end sections 39 and 40; and finger 2|, by end sections 40 and 38.
The tongues 33, 34 and 35 are inwardly bent.
`tion 65.
Exceptional flexibility of the spider is as shown in Fig. l, and have a length suicient to positively engage a conductor or wire inserted therein. The biting edges of the tongues may be V-shaped, as shown by the mark 402:, formed on conductor 4I, or arch-shaped, as shown by mark 42, on conductor 43, or some other suitable shape, designed to prevent rotation of the conductor with respect to the jawsv to which they are attached. Eliminating such relative movement, as has been previously stated, will prevent wear of the surface of the conductors, and gripping surfaces of the jaws.
The modification just described combines the ordinary jaw spider and the positive initial-gripping means.
A somewhat similar combination is shown in Figures 5 and 6. Here the jaws 50, 5I and 52 are provided with apertures 53, 54 and 55. The spider or metal cap 56 is formed with extending fingers or prongs 51, 58 vand 5'9, passing through apertures 53, 54 and 55, respectively, and engaging wire end 68 extending therethrough, similarly to tongues 33, 34 and 35 as in Fig. l.
Thus the extending fingers or tongues for posi- 1 tive initial grip, pass through the jaws themselves and support them in proper alignment.
In the remaining modication shown in Fig. 7, the jaws 6I are provided with inwardly projecting shoulders 62, passing through apertures 63 positioned between annular ridge 64, and cylindrical gripping section 65 integral thereto. A set screw 66, passes through transversely formed, threaded recess 61, in section 65, to positively grip conductor 58 passing through the recess 69 located longitudinally of both ridge 64 and sec- A slot 10, in envelope 1I, permits a tool to be inserted for manipulating set screw 66.
A washer 12 is positioned between each set of jaws to prevent the conductor or wire 68 from projecting too far beyond its gripping section 65.
In each of the foregoing modifications, it will be apparent that the conductors are gripped even at zero tension in the wires themselves. Furthermore, when tension is created, the jaws are positively forced into' the tapered ends of the envelopes or shells, simultaneously increasing the gripping pressure on the conductor. When the tension is released or if the conductor is twisted, the jaws are nevertheless positively positioned with respect to the conductor and will move therewith.
I have thus described my invention, but I desire it understood that it is not confined to the particular forms or uses shown and described, the same being merely illustrative, and that the invention may be carried out in other wayswithout departing from the spirit of my invention, and, therefore, I claim broadly the right to employ all equivalent instrumentalities coming within the scope of the appended claims, and by means of which, objects of my invention are attained and new results accomplished, as it is obvious that the particular embodiments herein shown and described are only some of the many that can be employed to\attain these objects and accomplish these results.
