To all whom it may concern: Be
it known that I, EDWARD F. SCHOENTHALER,
a citizen of the United States, and a resident of Longbranch, in the
county of Monmonth and State of New Jersey, have invented a new and
improved Insulator, of which the following is a full, clear, and exact
description. The
object of the invention is to provide a new and improved insulator for
telegraph, telephone, and electric-light wires arranged to permit
convenient insertion of the wire to prevent accidental disengagement of
the wire from the insulator and to allow free longitudinal and
up-and-down movement of the wire in the insulator. The
invention consists of novel features and parts and combinations of the
same, as will be more fully described hereinafter and then pointed out
in the claims. A
practical embodiment of the invention is represented in the accompanying
drawings, forming a part of this specification, in which similar
characters of reference indicate corresponding parts in all the views. Figure
1 is a perspective view of the improvement as applied.
Fig. 2 is an enlarged transverse section of the same, and Fig. 3
is a sectional side elevation of the same on the line 3 3 of Fig. 2. The
block A, of glass, porcelain, or other suitable insulating material, is
mounted on the supporting-pin B of a cross-arm B’ or other suitable
support, and on each side of the block A is formed a
longitudinally-extending opening A', elongated in a vertical direction
and adapted to loosely receive wires C for the transmission of
electricity. Access is had
to each of the openings A' by a transverse slot A2, leading from the
side of the block A into the opening A', at or near the middle thereof,
as plainly indicated in Fig. 2, so that the wires C can be readily
passed through the slot A2 into the corresponding opening A’. After a wire is thus placed in position on the block A the slot A2 is sealed or closed by a closing-wire D, passed through longitudinal openings formed in the block A above and below the slot A2, and the ends of this wire are twisted together, so as to form a loop which bars the wire C from passing out of the corresponding slot A2. |

Now
by the arrangement described each wire C is held against accidental
displacement from the block A, owing to the closing-wire D closing the
slot A2 against the corresponding wire C; but the latter is free to move
up and down, so that the wire is not liable to be broken or unduly
stretched between adjacent telegraph-poles, especially if the insulators
for a wire on adjacent telegraph-poles are on different levels. The
wire C is tied against lengthwise movement in the usual manner by a
tying-wire F, secured at its ends on the wire C on opposite sides of the
insulator and extending in a groove around the insulator, as plainly
shown in the drawings. By
having two openings A' and slots A2 on opposite sides of the insulator
the latter is rendered segmental, and either opening may be used for a
wire C. Having
thus described my invention, I claim as new and desire to secure by
Letters Patent-- 1.
An insulator for electric wires, comprising a block of an insulating
material having a longitudinal opening elongated in a vertical
direction, a slot leading into one side of the opening and an opening at
each side of the slot, and a closing-wire for closing the said slot,
said wire being passed through the said openings and having its ends
secured together as set forth. 2.
An insulator for electric wires, comprising a block of an insulating
material and having a longitudinal opening in each side, the openings
each being elongated in a vertical direction, a slot leading into one
side of each opening, at about the middle thereof, and a longitudinal
opening above and below the slot and a closing-wire on the said block,
for closing the said slot, the closing-wire extending through the
longitudinal openings above and below the said slot, the ends of the
wire being twisted, to form a loop, as set forth. In
testimony whereof I have signed my name to this specification in the
presence of two subscribing witnesses. EDWARD
F. SCHOENTHALER. Witnesses: F.
