i WIRE STRETCHING AND `SPLICING' DEVICE.

1 Speciiication of Letters Patent.

Patented April 27, 1909.

Application filed May 7, 1908. Serial No. 431,492.

To all whom it may concern: l s

Be it known that I, PAULO. LARsoN,a

becomes necessary when wires arey cut, or`

broken by accident ,accumulation of sleet etc.

My invention consists broadly of al unitary device for stretching-and splicing the ends of broken wires; it consists further incertain novel features of construction, arrangement and combination of parts as'will be hereinafter fully described and pointed'out in the claims, referencebeing had vtoV the accom-` panying drawing, inwhiche l p Figure 1 is aperspective view ofmy improved device; Fig. 2`is a central'vertical section of the same; Fig. 8 is a vertical section taken on line 3-3 of Fig. l; Fig. lisa similar section taken online4-4 of Fig.. l; Fig.5 is

a vertical section taken on line 5 5 of Fig. 2

Fig. 6 is a perspective'view of the twisting plug removed from the frame. Fig. 7 is a perspective view of a wrench used to operate the twisting and stretching members. Fig. 8 is a detail'view of a wire splice tube.

In carrying out my invention I use a frame consisting of the side members AA and the end, member A which connects the ends of said side members. The side members are further connected by a bracelate or bridge A2 between their ends, said race plate being mortised into the upper faces of the side members, and rigidly secured to the side pieces by screws passing through the sides and into the brace plate.` The end piece A has a central circular opening A3 therethrough, and a vertical' open slot Atextending upwardly from the o ening A3. The brace plate A2 has an o` en s ot A5 extending diagonally upward to t e upper` edge of said brace plate; this slot is provided with two circular enlarged spaces A which extend artly through said plate Az-see Fig. 2%.

n the o en end of the trame is journaled a spindle A7, having on one end a ratchet As which lies against the outer face of one side piece of the frame, while the opposite end of this spindle'is reducedV and squared as at A9 to receive the jaws of a wrench, the spindle being prevented from sli ping out of the frame by means of a pin 10 passed through the s indle A7 outside the frame.

VVlthin the circular` opening A3 of the end bar A is ada ted to be placed a plug which has the lcircular portionA11 and the square head A12; the square head has the diagonal slot A13 extending all way through same, while the circular portion A11 has the slotA11 which coincides with the slot A1s in the square head; the slot A11 has the two circular enlarged spaces A15, and the circular portion of the plug has in its outer face the notch A1G which is adapted to be engaged by the spring actuated pivoted latch A17 dis osed within the frame. A spring controlle pawl A18 is pivoted to the outside of the frame adjacent vto the ratchet A8 and is adapted'to engage the samejand prevent and permit its rotation whenldesired. o

In Fig. 2 is shown a portion of a wire joint B, of acommon and well known type which consists of two connected tubes made of some malleable substance so that they can be readily twisted; this joint is adapted to be placed in the position shown inFig. 2 `with its'ends projecting through the enlargements A1 and A15'in the parts A2 and A11 respectively when in use.

When it Vis desired to use my device to splice a broken wire one end ofthe wire is fed through the plug and through the lower tube ofthe joint and the extreme end passed through the opening A11 in Vthe spindle A7. The other end of the broken wire is passed over spindle A7 and through the up er tube ofthe joint B and through the slot 13 in the square head of the plug in the other end of frame, and the wire given a fewturns around the said squarehead; the wrench C is now placed on the square end of spindle A7 and the spindle turned, thereby stretching and pulling the wires to take up any slack that may exist. The large end ofthe wrench C is `now laced on the square head of the plug and t e plug given several turns which acltion, byA virtue ofthe ends of the tubes forming lthe joint B bein within the enlar ed spaces A15 ofthe circu ar portion of the jjug will twist the tubes (they being mallea le) andthe wires within them and form a erfect splicing of the broken ends of the Wire, the latch preventing longitudinal movement of the lug; the spindle A7 is now reversed to slac ren up the wire; the wire wrapped around the plug is now unwrap ed and the plug removed from the frame, t e latch A being thrown up out of engagement with the plug, and the end of the wire which projects beyond the frame is cut, the end of the wire toward the spindle being cut near the lioint B. The splice is now complete.

If desired, a splice of the broken ends of a wire may be made without using a joint sleeve B. The small cut-oli space A20 is made to insure the propel' position of the plug when putting it into the frame.

It will be seen from the above that l provide a simple and eliicient device for spliein wires and also a device which will stretch the wire, both operations being performed by the simple unitary device. 1

l claim:

1. In a device of the character described, a frame consisting of side bars and an end bar, said end bar having a central circular opening and a vertical slot extending therefrom,

a rotary stretching spindle mounted transversely in the opposite end of the frame, a removable rotatable plug having a circular portion mounted in the circular opening in the end bar and a squared head beyond the end bar to receive a wrench, said plug also having an open slot in one side and axial enlargements extending from said slot, and a transverse guide block rigidly mounted in said frame intermediate the stretching spindle and the rotatable plug, said guide block having a diagonal open slot in its upper portion to receive the overlapped ends of a broken wire.

2. In a device of the character described, a frame comprising side bars and a transverse i i l l end bar, a rotary stretching spindle transversely mounted in the opposite end of said frame, the transverse end bar having a eircular central opening and a slot extending therefrom, a removable rotatable plug having a squared head and a circular portion 'l`1tting within the circular opening of the end bar, said plug having an open transverse slot and axial enlargements extending from said slot, a transverse guide block rigidly held between the side bars of the frame intermediate the stretching spindle and the aforesaid plug, said guide block having a diagonally disposed open slot from its upper edge and axial enlargements extending from said slot, the en largements in the guide block and the rotatable plug adapted to receive the ends of a malleable splice tube, and a latch engaging the plug` and locking the same against longitudinal movement and detachably holding the plug in place.

3. ln a device ol the character described, a frame, a rotary stretching spindle mounted in one end of said frame, a removable rotatable twisting plug mounted in the opposite end of the frame, said plug having an open transverse slot and axial enlargen'ients extending from said slot, and a head portion to receive a wrench, a guide block rigidly mounted in said frame intermediate its ends, said guide block having a diagonally disposed open slot extending from its upper edge, and axial enlargements extending from said slot.
