To all whom it may concern:

Be it known that I, MIL'roNE. ANDERSON, a citizen of the United States, residing at Louisville, in the county oi..lefiersoi1 and State of Kentucky, have invented certain new and useful Improvements in Insulators, of which the following.- is a specification.

This invention relates to an improvement in insulators, the object being to provide a device of this character which will efl'ectually grip the ,wire without the necessity of winding or twisting-the same.

Another object of the invention is to so con 'struct the device that the same may be readily and conveniently secured 'to thefinsulator bracket.

In the drawings Figure 1 is a View showing the device in position on the bracket.

. Fig. 2a sectional view of the device. Fig. 3

adapted to receive the screw-threaded plug.-

15. The upper surface of this member is provided with grooves 16 adapted to receive 'the w1re16 said rooves beln .so arran ed as to allow the wire to be positioned at any angle. The clamped section'of the insulator consists ofa glass rne1nber'l7 which is provided with the flared extension 18 and the centrally arranged threaded aperture 19. It will be seen .that when the wire is positioned in one of the grooves 16' the member '17 when screweddown in the position shown in Fig. 2 will securely clamp said wire, the flared extension 18 preventing ice and snow from accurnilating lu'atweenv the insulator sections.

plug 15a formed of glass said It ill also be noted that the plug readily removed and replacedby, a new one when the same becomes worn.

In the modification shown in Fig. 4 the plug being integral with the section 12. i

The many advantages of a device of thi character will be clearly apparent as the same will not only be ciiicientin practice but economical-to manufacture. Particular attention is called to thetlared extension 18 which is arranged above the contacting surface of the member 17 thus allowing the wire to be readily inserted.

' What is claimed is: I

1; An insulator consisting of a lower section, said section'being formed with a plurality of threaded apertures, one of said apertures being adapted to receive the end portion of a supporting bracket, a screwthreaded plug adapted to rest within the other aperture, the upper surface of said section being provided with-grooves, an upper section, said upper section being provided with a centrally threaded aperture and an annular fiared extension formed integral with said npper'section. v

2;The combination with a supporting bracket having an upper threaded end, of an.

insulator base having a pair of 'alined threaded sockets formed therein and separated by. a partition of insulating material, one of said sockets being adapted to engage the threaded end of the bracket, an extei'iorly threaded wooden, plug engaged in the other socket of theinsul'ator base, and an upper insulator sectionhaving a threaded T socket formed therein to receive theupperend of the plug to permit the upper section to be screwed down I on the plug to Clamp ingly engage the bttSBSQCb-lOIIOffChG. insulater.
