Specification of Letters Patent.

Application filed May 15', 1919. Serial No. 297,304.

To all whom it may concern Be it known that I, TULLIE KING, a citizen of the United States, residing at Reynoldsburg, in the county of Franklin and State of Ohio, have invented certain'new and useful Improvements in VVire-Splicing Tools, of which the following is a specification.-

This invention relates to wire working implements, and more especially to tools for twlsting or splicing wire by means of. a revoluble head; and the object of the same is to improve the construction of such a tool.

The invention consists of improved means for retaining the wire in the slotted head, for actuating. said retainer automatically but permitting it to release the wire at a certainposition of the head, and in means for turning the head intermittentlyand for coilin or twisting one wire around the other in he ical form. v

Details are set forth in the following specification and claims and attention is invited to the drawings wherein:

Figure 1 is a front elevation of this tool, and I Fig. 2 isa side elevation. F i". 3 is a section through the sleeve and head: showing the latter turned so that its ,slot is out of register with the mouth of the sleeve.

Fig. 4: is a section on the line 4-4 of Fig. 3. I

Fig. 5v is a perspective view of the tool at work.

A handle 1 which is straight inthe pres ent case carries at one end a sleeve 2 consti tuting a bearing for the head to be described below, the sleeve being split at one side at 3 to produce a month which is herein shown as opening through the wall of the sleeve at its outer side directly opposite the handle. At a point about quartering to this mouth the sleeve has its wall pressed outward so as to produce an internal chamber 4.- for a purpose yet to appear. Formed on the handle are perforated lugs constituting guldes 5 through which slides the stem 6 of a pawl 7 and a spring 8 surrounds the stem between the head of the pawl and the rear guide so as to project the pawl normally to 1ts work.

Rotatably mounted within the bearmg or sleeve 2 is a head 12 whose general contour is cylindrical so that it fits the sleeve as best seen, in Fig. 3, and this head is slotted radially throughout its entire length from its axis to its periphery, as seen at 14. j A plate 10 isattached-by screws 11' or otherwise to one end of the head and bears against one end of the sleeve 2, while the other end of the head is notched and toothed on its periphery to. constitute a ratchet 17 adapted to be engaged by the said pawl 7. Thus the plate and the ratchet retain the head in the sleeve, andthe swinging of the handle and resultant movement of the pawl will cause the step by step rotation of the head in the sleeve.

The wire retainer best seen in Fig. 4 comprises a pair of-pins 20 mounted in holes 21 extending from the slot 14 outward at right angles thereto, and the pins have heads at their outer ends which may well be made in the form of a single member or short bar 22 connecting the two pins and adapted to stand within a peripheral recess 26 in the head 12, the recess beingshaped to receive the baror head element for the ins when it is pressed inward as seen in element, however, is of a size to move outward into the chamber 4 when the head 12' 2 turns to the proper point, which it will do at a time when the slot 14 registers with the mouth 3. For movin said bar outward, a spring '24 is mounted in a socket 25 as seen in Fig. 4. l I

Finally a spreader in the shape of a curved cam 30 is formed on one end of the rotary head, and preferably on that end; which carries the ratchet 17, the cam curving around the inner end of the slot 14 as shown in Figs.

1 and 5 and increasing in thickness from its low end 31 to its high end 32, while a hole or eye 33 is formed through its body radially of the head at a point adjacent said high end. This spreader may well be cast integral with the head.

1g. 3. ;This

ith this construction of parts, the use of the tool as best seen in Fig. 5 is as follows:

The wires W and W are to be spliced, and their inner ends are lapped as shown and held by pliers P, the inner end of the wire W being upturned as at U and passed through the eye 33. The other wire W is moved to the bottom of the slot 14, where it is retained by the tips of the pins 20 when they are projected art way into or perhaps entirely across said slot as seen in Fig. 3. The operator holds the pliers with one hand, and manipulates the handle 1 with the other, and the pawl-and-ratchet mechanism causes the rotation of the head within the sleeve. The eye 33 carries the upturned end Uof one wire around the body of the other, and at each revolution the spreader cam 30 causes the entire head to move along the wire W just the thickness of the wire being coiled around it, so that a neat helical coil is produced. After this end of the wire has been consumed, the slot is set in alinement with the mouth, when the spring 24: causes the retainer automatically to release the wire at the bottom of the slot, and the tool can be drawn off the same and reversed and the operation is repeated in the opposite direction on the end of the other wire.

Having thus described the invention, what is claimed as new is:

1. The herein described tool having a head provided with a radial slot for receiving a wire, a pin movable in the head to project its inner end across the slot near the bottom thereof, a bar at the outer end of the pin, the head having a recess for said bar, yielding means normally unseating the bar from the recess and retracting said pin, and means for seating the bar in said recess at will.

2. The herein described tool having a head provided with a radial slot for receiving a wire, parallel pins movable in the head on lines at right angles to the plane of said slot to project their inner ends across the slot near the bottom thereof, a bar connecting the outer ends of the pins, the head having a recess for said bar, yielding means normally ejecting the bar from the recess for retracting said pins, and manually operable means for pressing the bar into said recess at will.

3. In a wire working tool, the combination with a handle, and a sleeve carried thereby and split at one point and internally chambered at another, of a head rotatably mounted in the sleeve and having a radial slot and a radial hole intersecting said slot,

wire retaining means movably mounted in said hole and borne into active position by the walls of the sleeve but permitted to move outward into said chamber when the split and slot aline, a spring for so moving said means outward, and means for turning said head.

4. In a wire splicing tool, the combination with a handle, and a sleeve carried thereby and split at one point and internally chambered at another, of a head rotatably mounted in the sleeve and having a radial slot and a radial hole intersecting said slot, wire retaining devices movably mounted in said hole and borne into active position by the walls of the sleeve but permitted to move outward into said chamber when the split and slot aline, yielding means for so moving said devices outward, means for rotating the head around said Wire, and an eye on the head for carrying a second wire around the the latter by swinging the former, and a feed cam on one end of the head around the inner end of its slot and having an'eye for the other wire.

In testimony whereof I afiix my signature.

TULLIE KING. 1 8.]
