E. H. BUCKLEY TUBULAR INSULATOR Filed 001;. 27, 1925 Patented July 24, 1928.
UNITED STATES EDWARD H. BUCKLEY, OF PHILADELPHIA, PENNSYLVANIA.
TUBULAR IN SULATOR.
Application filed October 27, 1925. Serial No. 65,081.
My invention relates to tubular insulators especially adapted for use in conjunction with the lead-in wire of a radio antenna.
The objects are to provide a tubular insulator which will efliciently insulate the leadin wire from the support; which may be easily attached to make a water-tight connection with the support, and which may be readily severed to the proper size to fit the support.
These objects, and other advantageous ends which will be described hereinafter, I attain in the following manner, reference being had to the accompanying drawlngs in which Figure 1 is a fragmentary section through a window showing my insulator attached thereto, and
Figures 2 and 3 detail views of the elements which form my insulator.
Referring to the drawing, 1 indicates the window sash having an opening 2, my 1nsulator passing through the opening and having a water-tight connection therewith,
2 .and 4 a wire, such as the lead-in wire of a radio antenna passing through the insulator and having a water-tight connection therewith. For purpose of illustration, I have shown the insulator attachedto a window sash but it may be applied equally well to any other part. The window sash Wlll hereinafter be referred to as a support.
The insulator includes a tube 5 of insulating material having spaced pro ectmg part 6, preferably in the form of annular shoulders, on its outer face. The tube is positioned in opening 2 so that the end shoulders 6 are disposed a short distance from each side of the support. A pair of compressible washers 7, preferabl of rubber, fit over the end of the tube an .each has 1ts inner side 8 dished and pressing against the side of the support and its outer side abuttin an end shoulder 6. The washer is prefera ly thickest at its center and tapers to a thin edge so that it will easily bend to bring a large part of the dished inner side into contact with the side of the support to make an eificient seal. It also imparts a neat appearance at the juncture of the insulator and support. The washer, when free, takes the shape indicated in dot-and-dash llnes at 9, and when in position, it is distorted and produces a pressing action against the side of the support and the shoulder and thus makes a water-tight seal. The spacing of the shoulders ma be varied as' indicated by dot-and-dash l1nes at 10, so long as sufficlent space is left between shoulders for a washer 7.
For severing a tube too long to neatly fit the support, I provide a groove 11 in the outer face of the tube, preferably adjacent a shoulder so that the strength of the tube at that point is so reduced that a bending straln on the tube will cause it to break at the groove.
Wire 4 passes through tube 5 and the clearance space between the wire and the tube is sealed by a rubber cap 12 fitting over the end shoulder 6 and having an opening 13 through which the wire passes and makes a water-tight fit with the cap.
To apply the insulator to a support, the tube, shown in Figure 3, is first severed to be of the length shown in Figure 1. It is then passed throu h opening 2 in the support and washers slipped over end shoulders 6 so that the dished inner side 8 of the washers bears against the sides of the support. Cap 12 is then placed over the outer end shoulder 6 and wire 4 passed through opening 13 and through the tube.
An insulator attached to the support in this manner, makes a water-tight seal, is
neat in appearance, and may be easily attaohed.
While I have described my invention as taking a particular form, it will be understood that the various parts may be changed without departing from the spirit thereof, and hence I do not limit myself to the precise construction set forth, but consider that I am at liberty to make such changes and alterations as fairly com-cwithin the scope of the appended claims.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is -1. In an insulator of the character described, a tube adapted to pass through an opening in a support, a shoulder formed on the end of the tube, and an elastic cupped washer on the tube and adapted to abut the shoulder and a face of the support; said washer being imperforate except for a central tube receiving aperture whereby the washer will seal the opening through which the tube passes.
2. In an insulator of the character described, a tube adapted to pass through an opening in a support, shoulders formed on llt the ends of the tube, and an elastic cupped washer on the tube and adapted to abut each shoulder and a face of the support; said washers being imperforate exce t for a tube receiving aperture in each an thicker adjacent said aperture than at their edges whereby said washers will secure the tube in the su port and seal the aperture through which said tube passes.
3. In a tubular insulator adapted to carry a conductor through an opening in a sup-. port; means for sealin the end of the tu and the opening throng the support including shoulders formed on the ends of the insulator; soft rubber cupped washers, imperforate except for a central 0 ening, mounted on the insulator and each a utting a shoulder and a face of the support; and a rubber cap, imperforate except for a conductor receiving aperture, ripping one of the shoulders and the con uctor, substantially as described.
In testimony whereof I have signed my name to this specification.
EDWARD H. BUCKLEY.
