IMPROVEMENT IN TELEGRAPH-INSULATORS.

Specification formirg part of Letters Patent No. 149,763, dated April 14, 1874; application filed December 31, 1873.

UASE A.

To all whom it may concern:

Be it known that I, CHARLES L. Ln BARON, of Pensacola, in the county of Escambia and State of Florida, have invented a new and Improved Bracket-Insulator for Telegraph Wires; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being bad to the accompa- .nying drawing forming a part of this specification, in which Figure 1 represents the insulator attached to a post and supporting the line-wire, in perspective. Fi 2 is a top view of the device.

The invention relates to an insulator having two slots arranged at right angles to each other, one being open to receive the line-wire, the other closed to adapt the bracket to be The former is deeper than the other, so that the wire may be placed in the insulator before it is hung on the spike, as hereinafter described.

To this end I construct the device A of any suitable non-conductin g material-as glass or wood-and give it, preferably, a rectangular form. To adapt it for attachment to the pole or post by a spike, B, I provide it with a vertical slot, 0. The spike has its outer end bent upward to hold the insulatorin place; but, as

an additional means of seeurin g it, I generally employ a tie-wire, I), which is secured around the block just below the spike in shallow grooves or notches a, as shown. The slot E for holding the 1ine-wire F is diagonal to the line of direction of the latter, or to the face of the block A, except at its lower part, where it is somewhat enlarged. Thus a shoulder is formed at c, which prevents the wire rising in the slot and coming in contact with the spike.

As a further means of securing the parts to gether, a wire, c, maybe tied loosely around the line-wire E on each side of the insulator, passing intermediately under the end of the same. Small knobs or projections '2 are formed on the inner side of the insulator, which cause the water to drop from it in place of flowing to the post G; and the operations of putting up or of taking down or splicing the wire are performed with greatease and dispatch where this insulator is used.

The wire is allowed longitudinal, and also some lateral, movement in the slot E of the insulator; hence neither is so liable to be broken when the wire sways or is bein g ti ght ened, &c., as in the case of most other insulators.

The line-wire is necessarily placed in the slot intended for it before the insulator is hung on the spike, and it cannot become detached so long as the insulator remains suspended, whether tie-wires beused or not. The head or bent-u p end of the spike, while easily passed through the vertical slot, also prevents the insulator slipping oft, whether the tie-wires be used or not.

I do not claim an insulator diagonal or spiral slot 5 but \Vhat I claim is- The insulator provided with a slot for the line-wire, formed at a right or nearly right an gle to a slot for a spike, and extending below the latter, as and for the purpose specified.
