EDWARD BURTON, OF ANSLEY. NEBRASKA.

INSULATOR.

Specification of Letters Patent.

Patented Jan. '18. 1910.

Application filed February 4,1909. Serial No. 476.077.

To (1H aU/'loin it mog; concern.'

lie it` known that l, llnuxinn lllu'rox. a citizen olI the linitell Statua, reading' at Anslejv. in the county of (luster anll State of Nebraska, have invented certain new and useful Vimprovement` in Insulators: and l do hereby declare the following' to he a full. clear, and exact description of the invention,y Such will enable others skilled in the art to which it appertains to make anll une the saine.

The inventionrelates to an insulator and more particularly to the class of insulators for clamping or holding electric wires or cables.

The primary object of the invention is the provision of an insulator for Securing and holdingin place conducting wires, cables' or the like for use in telephone, telegraph and railwair trolley linea 'anll which insulator will permit the realll"l and quiet; adjustment of the ronllnlftim,r Fil-nient in pouition therein to properly clamp the sante. l lli-"luther ohjelt ot" theinvention is the provision of an insulator which eomprisea a bracket member adapted 'to be suitablyl secured to the cross head of the pole and which bracket is adapted to receive a out portingF block preferablyv ot' glass forming the inaulating medium through which llames the conlluetilmr element to Support the Yanule in proper nmition and the said block being securely helll in the bracket by a Crohn pin or other fastening member.

A still `Further object of the invention is the provision olf an insulator which is Simple in construt-tion.y thoroughly ellieient. in operation. anll inexpensive in the. manu'lal'- ture.

lilith these and other Objects in View the invention consiats in the construction` com hinatioit and arrangl'imert of part l as will he hereinafter more fully described in detail. illustrated in the acclunpanying drawings which disclose thtl preferred forma of emhl'iliiuient ot' the invention and as brought out in the appended claim. lit. is or' course to be under-:dood thatA minor changes in con struction, size anl, proportions of the parts elmatituting the invention may be malle Without departing 'from the spirit. thereof and aa come properly within the scopo of the aliliienllell claim. i

In the drawings: Figure l is a Hille elevation of the invention. Fig. 9. is one enll lieu' thereof. Fig. 3 is a longitudinal seei tional rien' through the bracket and the insulator block. ["ig. l 15 a perspective detail View ot' one ol the aeltiona of the insulator block removed from the bracket.

Similar reference characters indiifate corresponding parts throughout the several tiene in the drawinffs.

In the drawings the numeral 5 designates a metaHite-bracket although it ma)y he of any other suitable material 1f founll desirable and comprises a base (i having ri iug centrallytherefrom a Stem or upright T the same, terminating in spaced parallel aille members 8 between which are removably fitted the insulating medium.

The insulating medium comprise a aubstantially squared Shape block formell of separable Sections il und l0 preferably of glass although they may be of au)I other non-conductingt material anll each of said blocks contains in itasille anll bottom faces a grooves of the saill hloek l are received the menthol-:3 t5 ot'A the aten: or upright 7 of the bracket, so as to ha vo the Said shoulders pro jelft outwardly beyond opposite eliges of the members H and thereby irmly holll the inoulating medium in the bracket aull against lliaplaeenlent. Centrally in the inner faces of the sectionall il and 10 of insulating inl-- tlium are. coextlnulile registering grooves 13 for the reception ot' a` conducting element auch as a wire or lable (not alla wn,

To hold the block clamped in the bracket there is provided a cross pin L4 removably( mounted in suitable openings formell in the extremities ot the members 8 and extending transversely across they top of the insulating mellium formell by the sections S) and 10. It is obvious that by removing the pin 1l the said sections .3 andi l0 can be readily withdrawn from the bracket to insert or remove a conducting' element` from the registering grooveh` in the eeetions forming the insulatii medium. The basse 6 ol the bracket n3 proyilled with suitable openings to permit the Seruring.;r of the said bracket upon the cross head or bottom of a pole or any other suliporting structure or member.

That is claimed is- .\n insulator comprisingr a bracket formell of a lingle strip of material of uniform eine throughout its length and bent to provide an inver-tell T-shaped lower Supporting portion with spaced parallel yieldable ears ris- 'ing therefrom, a vertically split insulator i eng-ging the ears to clump the mrtiom` of G block forming separable Sections mounted the block together.
