UNITED STATES JAMES M. BROW'N, OF PITTSBURGH, PENNSYLVANIP A53 PATENT QFFICE.
21% TO VIESTINGELOUSE INSULATOE.
Application filed January 12, 1920.
My invention relates to insulators and particularly to insulators of the pin type.
The object of my invention is to provide means for effectively binding and holding an insulator and its pin in permanent relative positions and for preventing the admission of moisture therebetwcen.
In practicing my invention. I provide a pin. preferably of metal, although certain well-known insulating materials may be em ployed, having an outer screw-threaded end portion of relatively wide pitch and an intcrmediate screw-threaded portion of relatively narrow pitch. The outer portion is adapted to receive an insulating member, preferably of porcelain, and the intermediate portion is adapted to receive a binding member or nut to force the insulating member and the pin into binding relation. A member of yieldable material, preferably lead, is interposed between the insulating member and the binding member to lock the parts together and to provide a tight joint between the nut andv the insulating member.
The single figure of the accompanying drawing is a view, partially in elevation and partially in section, of an insulator embodying my invention.
A pin 1, preferably of metal, is provided for a distance adjacent to one end, with screw threads 2 of relatively wide pitch and relatively smooth rounded contour tor the reception of an interiorly threaded hollow insulating member 3 having petticoat portions 4 and an end portion 5 that is adapted to support, in any suitable manner. a bus bar, transmission-line or other conductor (not shown).
An intermediate portion 6 of the pin 1 is formed with threads of relatively narrow pitch to receive a nut or threaded sleeve 7 having an outwardly-curved flange 8.
A sleeve or washer 9. preferably of relatively soft material, .such as lead, is formed with an outwardly-projecting flange 10 and a tubular portion 11, in order that it may conform to a curved lower portion 12 of the insulating member 3 and assume a concentric position about the pin 1 in a recess 13 of the sleeve member 7.
The pin 1 is a slightly less diameter at its outer end than at its intermediate portion and, therefore, freely receives the sleeve member 7.
During the assembly of the insulator, the members 7 and 9 are "3 "st placed in position on the the insult Kg mem er 3 is then placed 0" the end oi the pin and adjusted to any desi ed position. A fter this, the member 7 is advanced toward the outer end of the pin, carrying the sleeve 9 with it, until the latter engages and is partially crushed against the insulating member 3v This binds the ain and the insulating member firmly toe'ether to reclude relative movements thereof and provides a: p .rmanent moistureproof joint thcrebetween.
While I have shown and described a prefer-red embodiment of my invention, alterations may be effected therein without departing from the spirit and scope thereof, as set forth in the accompanying claims.
I claim as my invention:
1. The combination with an insulator of the pin type comprising a screw-threaded pin and an insulating member threadably mounted thereon, said insulating member having an end portion sloping relative to an intermediate portion of the pin, of means for holding the insulating member in position comprising; a second member having a portion substantially conforming); to the slopinp; portion of the insulating member, and a nut on the pin havinq' a portion for holding said second. member in position.
2. The combination with an insulator of the pin type comprising a scrw-threaded pin and an insulating); member threadably mounted thereon, said insulating mei'nber having an annular sloping end portion diverging; from an intermediate portion, toward the outer end. of the pin. of means for holding); the insulating member in position comprising cushioning means having portions disposed about the pin substantially conforming to the sloping portion of the insulating member, and a nut on the pin havprojecting portions adapted to bindiugly hold the sloping portions of the cushioninp; member relative to the sloping portion of the insulating member.
The combination with an insinator of the pin type com ising a screw-threaded pin and an insula member threadably nounted thereon, said insulating member having an annular sloping end portion divero'ing from an intermediate portion, to-
ward the outer end of the pin, of means for holding the insulating member in position holding the flaring portion of the cushioncomprlsing a tubular eushloning member mg member against the sloping portion of having an outwardly flarlng portion disposed the insulatmg member.
about the pin substantially conforming to the sloping portion of the insulating memsubscribed my name this 19th day of De- In testimony whereof, I have hereunto her, and a nut on the pin having a sloping cember, 1919.
projecting tubular portion for bindingly JAMES M. BROWN.
