Serial No. 723,248.

of a novel form of splicing device adapted to form a splicing loop in connection with an already formed loop of wire and in such a manner, that the loop formed will take up the slack in the wire simultaneously with the forming thereof so that when the device is removed, the wire will be properly spliced and in the desired taut condition.

A further object of the present invention is the provision of a novel form of wire splicer, having means for retaining the free end of one of the splicing loops, and for guiding the adjacent strands, a wire guide and mandrel being provided for retaining the formed loop in co-active relation with the loop about to be formed, so that when the tool is rotated transversely of the wire, the wire will be stretched at the same time that the final loop is formed, it simply being necessary to cut the connected portion of the wire from the device after the formation of the splice and the connection of the terminals of the wire.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings-Figure 1 is a perspective View of the wire splicer in the initial posit-ion of forming a splice. Fig. 2 is a similar view of the device in its final spliceforming position and previous to the cutting of the wire from its spindle. Fig. 3 is a plan view of the wire guide and mandrel of the device. Fig. 1 is a longitudinal sectional view through the wire guide and mandrel of the present device, the tying spindle being shown in cross section. Fig. 5 is a plan view of the formed or finished splice.

Referring to the drawings, the numeral 1 designates the spindle of the device, which has formed integral therewith or in fixed relation thereto, the crank 2, the other end of the spindle being shouldered as at 3 for insertion within the rectangular aperture 4 formed in the oppositely disposed operating member 5 having a crank 6. A cotter 3 is disposed to detachably connect the member 5 upon the spindle 1 and said'member 5 is provided with the short end 7 which constitutes an. additional handle for transversely rotating the complete device as will presently appear.

Formed centrally through the spindle is a wire receiving aperture 8 while disposed within the spindle at equidistant points from the aperture 8, are the pins 9 which constitute a limiting means for the spaced apertured terminals 10 of the wire guide and mandrelll. This mandrel 11, as clearly shown in Figs. 3 and 4, consists of the parallel members or ends 12 having the sharp or pointed terminals 13 with the loop receiving throat 1 1 terminating in the sharp points 15, these two parallel members 12 being held together by means of the bridging plate 16, all of which in the present instance are formed integral from a single stamping. It will thus be seen that the wire guiding and mandrel device 11 is rotatably mounted upon the spindle 1 so that the loop L, as clearly shown in Fig. 1, at the initial step will be held in a horizontal position or with its extreme end engaging within the throat 1 1 of both of the parallel members 12, while the strand 17 will have its terminal 18 passed through the aperture 8 of the spindle 1, and twisted thereupon by rotating the spindle 1, with the main strand 19 passed over the spindle 1 between the terminals 10 and the central aperture 8, the parts when in initial position assuming the position as shown in Fig. 1. At this step the wire is stretched by taking the slack upon the spindle 1 when coiling the end of the terminal 18 thereon.

In order to form the coil 20, as shown in 1 Figs. 2 and 5, the operator passes any holding means, as for instance pliers, through the loop L to hold the loop against rotation during the transverse rotation of the complete device. Thus the operator gripping the means for holding the loop L in one hand, rotates the present device by the other hand so that the new formed loop will have its terminal 18 twisted several times around the body of the strand, after which the spin dle 1 is rotated to release the terminal 18 from the aperture 8 thereof. The released terminal is then twisted about the strand to form the completed coil 20 and the splice, as clearly shown in Fig 5. The device is now removed from the wire as are also the pliers or other means used for holding the loop L against rotation.

In initially connecting the terminal 18 to the spindle 1, the strand 17 is passed through the loop L and the spindle 1 is rotated so as to form a coil of the terminal 18 upon the spindle, the parts assuming the position as heretofore described as shown in Fig. 1.

What is claimed is: A wire splicing tool, including a wire terminal receiving spindle, two oppositely Copies of this patent may be obtained for disposed cranks for rotating the same, and a wire guide and mandrel rotatably mounted upon the spindle for receiving the loop of one terminal during the rotation of the spindle and the transverse rotation of the tool to form the connecting loop, said wire guide and mandrel consisting of two spaced terminals rotatably mounted upon the spindle and having a loop engaging portion at the outer ends thereof for retaining a loop of one strand relatively to a strand to connect thereto.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
