TBANSPOSI'I'ION DEVICE FOR ELECTRIC LINES.

Patented Apr. 20, 1915.

Application filed July 6, 1914. Serial No. @154.

To all whom it may concern:

Be it known that I, GUY W. NEEL, a citizen of-the United States, residing at Dublin,

in the county of Erath and State of Texas,

have invented certain new and useful Imrovements in Transposition Devices for lctric Lines, of which the following is a specification. I

My invention relates to transportation devices for telephone lines and for other purposes, and the object is to provide simple and highly efiicientdevices for transposlng the line currents.

One object is to provide devices which cannot be destroyed by bullets or rocks and other destructive agencies.

Another object is. to provide simple devices which will maintain the lines parallel with each other.

Another object is to provide such devices so that no special tools will be necessary for linemen when arranging. the transposition so that a lineman will need only a pair of pliers.

.An advantage is that a transposition of the lines can be quickly accomplished without interruptin the service for any considerable length 0 time.

Another advantage is that the transposition devices can be set away from a pole so that they will not be in the way of the linemen when climbing about the poles.

Another advantage is that as many transpositions can be installed at a pole as there are lines to be transposed.

Other objects and advantages will be fully explained in the following description and the invention will be more particularly I a pointedout in the clalms.

Reference is had to the accompanying drawings which form a part of this applica-' tion.

Figure 1 is a plan view of a transposition device connectingor transposing two lines. Fig. 2 is a variation of the devices shown in Fig. 1. Fig. 3 is a side elevation of one of the connecting and clamping devices. Fig. 4 is a plan view of devices for transposing four lines.

Similar characters of reference are used to indicate the same parts throughout the several views.

One of the princlpalparts of the transpo- I at each end. A metallic cut! 2 is screwed on connection or cuff 2. A bolt 5 is mounted in r the insulation 4 with a head 12 inclosed in the cuff 2. 'A conducting wire 8 which is provlded wlth double insulation 9 and 10 is mounted in the pipe or casing land connected to the head 12 of bolt 5. A clamping and connecting member is provided and consists of a block 6 which has preferably a corrugated face 16 and a cooperating block 17 -with a corrugated face 18. A bolt 19 with a thumb nut 20 is used to bind the blocks 6 and 17 on a line wire. A line wire 21 is placed between the blocks 6 and 17 and then the nut 20 is turned to bind the blocks on the line wire 21 so that the line wire may be cut.

When the wire 21 is cut, it may be wound one or more times about the bolt 5 to prevent slipping through the blocks 6 and 17. The wire 21 is thus electrically connected to the bolt 5 and the bolt 5 is electrically connected to the wire 8. Duplicate cap 3, insulation 4, and end 2 are provided for the other end of the casing 1. The wire 8 is electrically connected to a bolt 5 which is electrically connected to blocks 6 and 17 similarto blocks previously. described. The line wire 22 is electrically connected to the block 6. This completes the transposition of one parallel line. A boss 15 is formed on the casing 1 and bolt 11 is electrically connected vto the boss 15 and also electrically connected boss 24 is formed on the other end of the pipe 1 and a bolt 25 is electrically connected to a connecting and clamping member 27 and the connecting member 27 is electrically connected to a line or wire 26. This completes a description of the transposition of the other line of a circuit. The line 26 is the line which was cut from the line 22. The

current from line 23 to line 26 runs through the connecting member 7, the metal of pipe 1 and the connecting member 27. The lines will thus be parallel after they are transposed.

An illustration of the manner of trans:

posing more than two lines is shownin Fig.

4. A casing 28 is' provided for transposing utilized to make the lines. Connecting members2? similar to connecting member 6 are provlded. The casing 28 is provided with msulation and other members similar to bolt 5 and insu-- lated wire 8. The line 31 is intercepted and transposed as wire 32. The wire 33 is intercepted and transposed as wire 34. The wire 35 is intercepted and trans osed as wire 36. The wire 37 is intercepte and transposed as wire 38. The wires 37 and 38 are connected to the casing through bosses 39. The four wires are thus transposed and are parallel before and after transposition.

The transposition devices can be placed wherever desirable, as many as three or four between each pole if necessary.

The variation shown in Fig. 2 may be the construction cheaper. The wire 8 may be left out of the pipe 1. The transposition can be effected by connecting the connecting member 6 with the connecting member 6 at the other end of the pipe by a rod or bar 40 which is raised high enough from the pipe 1 to prevent shortcircuiting, or the bar 40 may be run below the pipe 1. The connections with the pipe -1 and with the pipe or casing 28 should be Water-tight.

What I claim, is,-

1. Transposition for telephone and other wires comprising a tubular metallic casing set at right angles to the line wires and havmg terminals bent in opposite directions, an insulated wire running through said casing and through said terminals, means for connecting said wire with the line wires, 'in tegral bosses formed on said casing opposite said terminals, and means for connecting said bosses with the line wires.

2. Transposition for telephone and other line wires comprising a tubular metallic casing having its terminals bent in opposite directions, ing and a wire running through said casterminals and insulated therefrom,

means for electrically connecting the ends of said wire with line wires, and means for electrically connecting line wires with said casing opposite said terminals.

Transposition for telephone and other line wires comprising a tubular metallic casing having its terminals bent in opposite directions, a wire running through said casing and through said terminals and insulated therefrom, means for electrically connecting said wire with line wires, and connecting members formed integral with said casing ing its terminals bent in opposite directions,

a wire running through said casing and terminals and insulated therefrom, means for connecting the. ends of said wire with line wires consisting of bolts connected to the ends of the wires, detachable caps connected to the ends of said casing, and means for insulating said bolts. from said caps and casing, and connecting members formed integral with said casing at the bends thereof and projecting in opposite directions from said terminals.

In, testimony whereof, I set my hand in the presence of two witnesses, this 21st day of January, 1913.
