i This invention relates to' wire pullers or tighteners and has particular relation .to

those devices intended for the use of linemen wire as fence wire and telephone wire, it is desirableto have'a' construction which will work equally well between two wire ends and I also between a poster pole cross arm and the wire to be drawn taut. i

The primary object of this inventionfls the provision of animproved wire pulling device. I Another object of this invention is the provision of an improved wire pulling or stretching device with which it is possible'to take up slack, hold the slack and then take up more slack.

Another object of'this invention is the provisionof such a stretching or pulling device which may be engaged with the side of a post opposite to the directionfrom which the wire is being pulled and which will permit of the use of a hammer in the splicing, nailing, or

staplingoperation for securing the wire in place and without awkwardness on the part of the operator and without losing slack already-taken up by the pulling device.

Another and further object of'this invention is the provision of such an improved wirestretcher or puller that thetight wire may be brought up to a corner post and secured at a point where it is tight. I

Other and furtherobjects will be apparent to those skilled in the art from a reading of the complete specification and claims. Referring to'the drawing wherein I have illustrated an embodiment of my invention, Fig. 1 is a side view of my invention shown in use in connection with a post. i Fig. 2 is a View similar to Fig. 1 but showing the use of the device where a fresh hold .isfltaken on the wire for further tightening.

same or similar parts throughout the'several Views of the 'drawing. V I I In the draw ng, anelongated body member 10 is provided throughout its length with the spaced holding devices 11 inthe form of notches on one edge. i V At one endof the elongated member 10 is an. extension 12 which has a bentouter end 13- whichformsa loop, the end pointingin the general direction of thelength ofthe body portion. At the extreme end of the end portio'n13 is'a point 14 which is used to pierce a fence post, crossarm of a telephone pole or any other similar object to'which it may be D/lounted on the elongated body member is a carriage 15 whichhas a portion surrounding or partially surrounding the elongated body member-10. This carriagehas an outwardly extending arm 16 which, atits end carries ,a'wire' gripping or holding device. This holding-device comprises a bent-over end 17 which, with the endof the lever 18, exerts a grip on the wire. I

Connected to the carriage 15 by the link 19 is a lever 20. This lever 20 is shown of a U- shape form, the two portions of the U passing on opposite sides of the elongated body member 10. In addition to the pin connection 21 which pivots the lever 20 and the link 19 together, the lever 20 is provided with'afulcrum which is in the form of a pin 22. This latter is soplaced. on the lever 20 that it may have selective engagement with the spaced holding/devices 11 of' the elongated member 10.

the carriage and in position to engagethe holding devices 11, is

a backwardniovement prevention means in the form of a projection 23. a

At the end of the elongated body member 10, is a guide-carrying arm 24, carrying'a guide'wheel 25, pivoted thereon. To secure rying arm 24. VVhen' thesetwo angular bent ends 26, 27 with the bolt 28 effectually prevent movementof the guide-carrying arm 24 relative to the body member 10. The guide wheel 25 is shaped like a pulley block sheave to receive and guide the wire to be pulled.

At the end opposite to the guide carrying arm 24 ayvire holding or gripping means comprising alever 29 and anofl'set ear me1nber 30. The latter may be conveniently formed by bending the end of the extension 12, the looped portion 13 being welded in place or riveted as at 31.

The lever is of such len th that it maybe folded over the body portionas indicated at 32 in liig. 1.] t I a a V a y In operation thereare several methods of using the devic'e. Let us assume that a sin gle wire is to be pulled up to a post. The deviceis firstplaced with the point14 in the surface of the post opposite to the direction from which the wire is to be drawn.

.The slack is now taken out of the wire, the

wire being placed in the wire holding means 18, thc lattimbeing turned so that its end acent the turned portion 17 will engage the, wire. The wire contacting surfaces of the parts 17, 18 are roughened so as to better grip the wire, With the wire properly held to the ca riage asjust described, the operator takes the lever and causes the fulcrum pin 22 to engage one of the holding devices 11. p The leveris now drawn back which nioves the carriage forward. The projection 23 engages a holding device 11 as soon as the pressure released on the lever. The pin 22 isnowca sedto be engaged with a holding device 11 mane-awa din post P.

enough, the carriage 15 maybe operated past the post. Since'the carriage carries the Wire withit, it will be clearly seen that the wire will lie closeto the post when the carriage is in the extreme position. When in this eX- .ti'enie p0siti0n,,tl ie whole machine is swung on the point '14 as a 'center until the elongated body portion 10 is out of the way. The wire is now stapled in place. i V

. If the wire should be still too slack after first reaching the extreme position adjacent the extension 12, the free end of the wire isbrought around the eXtension 12 and fastened between the gripping surfaces of the parts 29 and '30. This holds the slack 'al ready taken up. By holding the pin 22 out of engagement from the holding devices 11 and swinging the lever 20 against the adj acent end of the carriage 15, by exerting pressure on the lever 20 (to the left in Fig. 2), the projection 23 may be released. The carriage may then be moved back adjacent the guide supporting member 24: or to such distance as the operator estimates will be necessary. The tightening operation is now repeated and when sufiiciently taut, the Wire is stapled or nailed as already described.

If is desired to tighten two wires for the purpose "of splicing, the wire ends are securedin the two wire holding or gripping means 17,18, and 29, 30. The lever 20 is now operalted to cause the carriage 15 to operate along the elongated body member 10 as already described. (hen the slack has I been taken up,the splice is made in the usual manner. I 1

It believed to be clear to one skilled in the art that l have produced a wire pulling machine which will serve the double purpose of drawing two wires together and drawing one wire toward a cross arm or post. In addition, the feature of taking up slack, holding what has been taken up and then taking up more slack, is important since it permits of the use of a shorter elongated body portion th'aiiwould otherwise be necessary. This means a lighter machine as a whole.

While I have shown and described in de tail an embodiment of my invention, I desire to have it understood that this'is merely iilustrative and that modifications and changes may be made Without departing from the spirit of my invention and within the scope of the appended claims;
