1 Claim.
This invention relates broadly to insulators, and more particularly to an insulator for use in connection with high-tension Wires.
An object of the present invention is to provide an insulator of this character which will be found especially useful for use on ships, where such insulators are subjected to abnormal, hard usage and handling.
In accordance with the present invention an insulator is provided to the end that the porcelain, or non-conductive section of the insulator, in case of breakage, may be readily displaced and the connections at the respective opposite ends of the insulator salvaged and used with the substituted porcelain or main body of non-conductive material.
A further object of the invention is to provide an insulator of the character mentioned that is so characterized by a combination and arrangement of elements as will permit the insulator to be readily assembled for use and with corresponding ease be disassembled for repair, storage, or other purposes.
The invention, together with its objects and advantages, Will be best understood from a study of the following description taken in connection with the accompanying drawings wherein:
Figure l is an elevational view of an insulator embodying the features of the present invention.
Figure 2 is an elevational view of the insulator taken at right angles to Figure 1.
Figure 3 is an end elevational View of the insulator.
Figure 4 is an enlarged detail View partly in section and partly in elevation and illustrating certain details of the insulator hereinafter more fully referred to.
Figure 5 is a transverse sectional view taken substantially on the line 55 of Figure 1.
Referring more in detail to the drawings, it will be seen that in accordance with the present invention the insulator embodies a body member 5 of porcelain, or other suitable non-conductive material.
The body 5, in the present instance, is illustrated as being in the form of an elongated cylindrical rod having at the respective opposite ends thereof integral substantially truncated cone-shaped knobs BB. The knobs 6, respectively, progressively increase in diameter from the point of merger with the body 5 to the extreme free end of the knob.
For each end 8 of the insulator body 5 there is provided a cap I.
The cap 'I is in the form of a relatively short cylindrical body provided at one end thereof with opposed apertured ears 88.
A conecting bail 9 is associated with each cap I and is pivotally secured to its cap through the medium of a coupling bolt ID that extends through apertures II and I2 provided in the extremities of the bail 9 and through the apertures in the ears 8.
One of the apertures in the bail 9, for example the aperture I2, is provided with threads, and the bolt I 0 has a threaded extremity IOa that screw-threads into the aperture I2 as shown to provide a positive connection between the bolt I0 and ball 9.
For positively securing the knob 6 of the body 5 within the bore of the cap I there is provided a sectional clamping bushing indicated generally by the reference numeral I3.
The bushing I3 may be formed of any desired number of sections, and in the present instance is shown as formed of but two complemental sections I4 I4.
The bushing I3 is in the form of a socket split longitudinally into the half-sections I l-44, and having a tapered body portion that conformably fits in the tapered bore l5 of the cap 1.
Also, the internal bore or Wall of the socket of the bushing I3 is tapered to conformably receive the knob 6 as shown.
To assemble the insulator, a cap I is first sleeved on one end of the body 5 past the knob 6. The sections I4I4 of the bushing I3 are then placed in position on theknob 6 after which the cap 'I and body 5 are moved in directions relative and opposite to one another in order to engage the bushing I3 Within the tapered bore I5 on the cap "I. This will result in a contraction of the bushing I3 about the knob 6.
Next the apertures I I and I2 of a bail 8 are aligned with ears 8-8, and the shank of the bolt I0 then passed through the aligning ears, with the sections We of the bolt threaded through the aperture I2 of the bail.
It will thus be seen that the bolt II] will bridge the wall of the cap 'I and thus serve to prevent axial separation of the parts I, I3 and 5.
It will be apparent that with an insulator of this character, should the body 5 break, it can be readily replaced; the cap I, and associated parts, being used with the replacing insulator body. Consequently, in the event of breakage, the entire insulator is not rendered useless, but rather such parts as the cap I, bushing I3, connecting bail 9 and bolt I ii are salvaged for further use.
The many advantages of an insulator of this character, from the standpoint of assembly, disassembly, cost of repair and replacement, etc. will, it is believed, be apparent from the above, and further appreciated by actual use of the inulator.
While I have herein illustrated and described what is considered the preferred embodiment of the invention, I am well aware that in the practical application of the invention minor changes, from desire or expediency, may be resorted to without departing from the spirit of the invention as herein illustrated, described and claimed.
Having thus described the invention what is claimed as new is:
In an insulator of the character described, an insulator body of dielectric material, and in the form of a rod having integral tapered knobs at the respective opposite ends thereof, said knobs respectively increasing in diameter from the point of merger with the rod to the extremity of said knob, a cap for each of the knob-equipped ends of said body, said cap being of substantially cylindrical form and provided with a tapered bore, a sectional tapered bushing seated in said bore and conformably embracing said knob, a connecting bail, and a pivot bolt engaging said bail and cap at one end of the latter, and extending diametrically of the cap in a manner to act as a stop for preventing axial separation of said cap, bushing and knob-equipped end of the insulator body.
