HARRY C. WILLIAMS, OF IRVINGTON,

NE IT JERSEY, ASSIGNOR T0 AMERICAN TELE- PHONE AND TELEGRAPH COMPANY, A CORPORATION OF NEW YORK.

MECHANISM FOR INSTALLING TRANSMISSION LINE-WIRES.

Application filed. November 2, 1917.

To all whom it may concern:

Be it known that I, HARRY C. WILLIAMS, residing at Irvington, in the county of Essex and State of New Jersey, have invented certain Improvements in Mechanism for Installing Transmission Line-lVires, of which the following is a specification.

This invention relates to apparatus for use in the construction of overhead transmission lines and more particularly to mechanism for installing line wires on crossarms and to facilitate the transposing of these wires.

Heretofore in installing line wires on crossarms it has been customary to connect the line wires to the pulling line by means of a device to which each of said line wires was attached in a fixed positionrelative to lVherever it was desired to transpose the wires of any pair or the pairs of wires, or both, it was necessary to disconnect thewires of a pair or the pairs of wires from the said connecting device and to transfer and fasten. them to their new positions thereon corresponding with the transposed position of the wires or pairs on the crossarrn or other supporting device. The use of a connecting device of this type i 7 causes much delay and introduces a possibility of error, which delay and error will be minimized through the use of this invention.

The object of this invention is, therefore, to provide an apparatus for connecting a plurality of line wires to a pulling line whereby all ofsaid wires may be supported in substantially the same plane, and each wire held securely in a definite position with respect to the other wires, and also having means associated therewith whereby the wires of any pair, or the adjacent pairs of wires, or both the wires and the pairs may be transposed, without disconnecting the wires from the said apparatus, and may be securely held in such transposed position.

This invention will be clearly understood by referring to the accompanying drawing of which Figure l is a perspective of the entire apparatus, a part of which is shown in section so as to disclose certain details, Fig. 2 is a perspective of a detail, and Fig. 3 is a perspective showing a method of using this apparatus.

In the drawing, 1 represents a yoke Specification of Letters Patent.

through the apex of which is placed an eye bolt 2, adapted to rotate about an axis substantially parallel with the axis of the pulling line. A nut 3, at the inner end of the bolt secures it to the yoke. Through the side of the yoke opposite the apex is placed a bolt 4:, rigidly fastened thereto by means of the nut 5. Coaxial with the bolt a is a spring 6, one end of which presses against the yoke and the other end against the washer 7, which is in contact with the memher 8. The said. member is prevented by the shoulder of bolt 4 from rotating about said bolt and is normally held in a fixed position by the spring 6, but it is capable of being rotated about said bolt. This will be more clearly seen by referring to Fig. 2 which shows in perspective, bolt 4, having a head 2%, and a shoulder 25 between the head 2% and the shank 26. The shoulder 25 has two parallel faces, one of which, designated 2? is shown and the other of which is similar and diametrically opposite, and the planes of these two faces are tangent to the shank 26. The slot in member 8 has two parallel sides and slightly rounded ends, the distance between the two parallel sides of the slot'being a trifle greater than the distance between the two parallel faces of the shoulder of the bolt. Two bolts 9 and 10, similar to but preferably smaller than the bolt 4, are attached to member 8, one extending through each end of said member, as shown in Fig. 1, and rigidly fastened theretoby means of the nuts 11 and 12, respectively. Around bolt 9 is placed a spring 13, one end of which presses against member 8 and the other end against washer 15, which is in contact with member 17. Two eyes, 19 and 20, are attached to member 17, one at each end, and adapted to rotate about an axis substantially parallel with the axis of the bolt 4. In a similar manner a spring l-Lt is placed around bolt- 10, one end pressing against member 8 and the other end against washer 16, which is in contact with member 18, the said member having two eyes 21 and 22 attached thereto in the same manner in which

eyes

19 and 20 are attached to member 17. Another eye 23, is securely fastened to the yoke and adapted to rotate about an axis substantially parallel with the axis of the bolt 4. function of each of said eyes is to a a lkl l proride rotatable means for connecting the line wires to this connecting apparatus. The

members

17 and 18 are prevented ii rotating by means similar to those prevent the member 8 from reta l are held in their normally i l positions by the springs 13 and 1- The apparatus here di for connecting the maximum 0 wires at the same time, and there customary to connect to the pul two of these devices having total ca of ten wir since this number of wires placed the sea upon the type of c sarin which is n most widely used in telephone and graph. line construction. owever, desired restrict the li form in which it is apparatus enibod gl v be designed to connect wires.

If it is desired to place five line wir upon crossarnis on a pole line, a pulln line is attached to the yoke by insei N in the eye of the eye-bol and seci inthe usual manner, and tire line ires connected

tothe eyes

19, 20, usually by inserting each of sa 1 through an eye and twisting the free end about the standing end of each wire, but some instances it may be desirable to connecteach wire to a snaphool; which, in turn, is connected to an eye of the connecting device. means of D0'\ 6lClll- 'Ql1 winch or a team of llOlcES, or other suitable method a force is applied to the pulling line wherebythe line wires are drawn from pole to pole in the manner shown in l'iig. 3,

At the point where, for example, it is desiredzto transpose the wires of one par, such as those connected to eyes 19 and 2 member 17 is pressed toward the "j l against the action of spring 13 suilicien far to lit the member 17 entirely above the shoulder of the bolt it may then he rotated about the bolt freely in either direction through an arc oi 180 when the pressure of spring 13 will cause said me noer to drop bacl; into its normal position against the head of the bolt where it is prevented from turning by the shoulder of bolt 9. if member 17 has been raised above the shoulder or" bolt 9, and is being rotated about the bolt, when said member reaches a position where the sides of the slot are parallel with the faces of the bolt, said member will drop into its normal position against the head of the bolt, and will be prevented from turnmanner similar to that in which member 17 held. lhe rotation of member 8 will transpose not only both pairs of wires, but

tae wires each of the transposed pairs. In order to remove the transposition of the wires of the pairs the members 1'? and 18 are rotat d in. direction opposite to that in which iii =3 8 was rotated, thereby remo 'n the to 1st from the wires, leaving the pairs only transposed.

The invention provides a simple apparatus-tor connecting a plurality of line wires to a polling line and for holding securely each of said wires in a definite position relative to the others, but so adapted that the i i airs may be transposed without 7 the wires from said appa re j facilitating the transposing oft and tending to minimize the pos l error which arises when the line disconnected from the connecting order to effect their transposixl hile, tor the purpose of illustration, the

in; "lotion has been shown as embodied in a sinale term, it is to be understood that the in ention is capable of other and widely ditt ant forms or" embodiment which fall wd'hin the scope of the appended claims.
