No. 887,520. PATENTED MAY l2, 1908 J. W. REHLING.





Specification otLetters Patent.

Patented May 12, 1908.

pplication iled September 6, 1907. Seriall No. 391,607. n

inexpensive construction to.which conductor wiresy may be readily engaged without the employment of a tie wire.

be fullydescribed hereinafter, Iin connection ,with the accompan 'ng-drawing which forms a part of this speci cation', and its novel' features will be Adefined in the appended claims.

In the drawing; Figure 1 isa view in perspective of an insulator embodying the invention, Fig, 2 isa horizontal section ofthe same on the` line 'rfof-,Fig 1, Fig. 3 isa perspective.l view of a modified construction of the device, and, Fig. 4 is a vertical section thereof.

Referring to Figs. 1 and 2, the numeral 1 designates a block ofY glass,or other vitreous" material formed with a central opening 2 to receive a screw 3 for securing the block to 'a suitable, support.` The upper side of the block 1 lis formed with V-shaped slots to provide two o positely projecting lugs 4 and 5, the vertice portions 6 of which are serrated to adapt them to grip a wire 7. vThe under side of the block is also provided with oppositely disposed lugs 8 andl 9 formed with serrations 10 to enga e a wire 11.`

As shown in ig. 1 the insulator constructed as above described is adapted to support two wires. l'

An important feature of the invention is,

The construction of the improvement will v Patent, is,

that a twist of the insulating blockwill bind the wire and makeit taut.

In ,the modiiication shown in Figs. 3 and 4 the block 12 of insulating material is formed with two screw holes 13 and 14, and is recessed vertically to provide two oppositely disposed lugs 15 and 16 having serrated surfaces 17 to engage a wire 18. This modified form of the invention as will be apparent, is designed for a single conductor Wire.

The improvement provides an insulator to which a wire or wires ,may be readily attached without re uiring the employment of tie wires or other astening means.

It will be seen that m improved insulator,

'as constructed, will rea ily take up anyslack ywire of the line, and by slightly turning the l device the Wire will be drawn taut, thus a particular advantage is produced for the rea. son that any slack wire may be easily taken .pp at any time by merely turning. the insu- Having fully described my invention what I claim a's new and desire to secure by Letters 1. An insulator, comprisin a block of nonconducting material, provi ed with o positely disposed lugs to engage a wire and aving serrated ksurfaces upon which the Wire rests.. A

'2. An insulator comprisin conducting material forme opening, and provided on its upper and lower` sides with oppositely-projecting lugs having serrated surfaces to grip conductor wires.

In testimony whereof I affix my signature in the presence of two witnesses.
