HENRY K. RUGER, OF BAY ST. LOUIS, MISSISSIPPI.
INSULATOR.
SPECIFICATION forming part of Letters Patent No. 367,164, dated July 26, 1887.
Application filed April 13, 1887. Serial No. 234,595. (No model.)
To all whom it may concern: Be
it known that I, HENRY K. RUGER,
of Bay St. Louis, in the county of Hancock and State of Mississippi,
have invented a new and Improved Insulator, of which the following is a
full; clear and exact description. My
invention has reference to the class of insulators for electric wires
called "self-tying" and has for its object to so improve their
construction that the wire can be readily and securely fastened thereto,
the accumulation of moisture therein around the wire will be prevented, while extreme simplicity and economy are obtained. The
invention consists in certain novel and useful features embodied in the
construction of my improved insulator, as hereinafter fully
described, and then definitely claimed. Reference
is to be had to the accompanying drawings, forming a part of this
specification, in which similar letters of reference indicate
corresponding parts in all the figures. Figure
1 is a front view of my improved insulator, showing a wire held therein.
Fig. A
designates the shank of the insulator, and B a support in which it is
keyed or secured in the usual manner. The
insulator is provided with the usual water-shed, and is cast or formed
in a single piece of glass or other suitable insulating material. The
tapering head of the insulator above the shed is cut or cast in a
peculiar manner, constituting the improvement herein claimed. The slot C is approximately U-shaped, starts at the front, and extends to the center of the insulator-head, the bottom D of the slot |
inclining
upward to said center, as shown in dotted lines in Fig. 2. The side
branches of the slot C approach the center of the insulator-head by
equal curves E, which meet the short vertical slots F, extending
downward therefrom at points diametrically opposite the center of the
head. The bottoms G of the vertical slots F are curved inwardly and
downwardly to the rear part of the bottom D of the slot C, so that any
water or moisture entering the slot will immediately flow out thereof,
thus preventing corrosion of the wire. To
apply the wire, it is bent upward to correspond nearly with the forward
U-shaped part of the slot C, and such bend passed into the slot to the
rear end. The oppositely-projecting parts of the wire are then bent
outward and downward, thus forcing them into the vertical slots F, in
which they are securely held by the tension on the wire. The
curves E of the slot C facilitate the pas- sage of the wire from said
slot to the vertical slots F. Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- An
insulator for electric wires, formed with a U-shaped slot, C, having
curved or rounding upper and lower surfaces and terminating in vertical
slots F, the bottoms of the slots F being curved or inclined downward
and inward to the bottom D of the slot C, and said bottom D being
inclined downward and outward, substantially as shown and described.

K. RUGER.
