names.
To all whom it may concern:
Be it known that I, GEORGE H. RUTLEY, a citizen of the United States, residing at Schenectady, county of Schenectady, State of New York, ave invented certain new anduseful Improvements in Fillers forCoils and the Like, of w iich the following is a speci-fi cation.
This invention relates to compounds adapted for use in connection with some of the solvent oils, such as transil voil or the like.f.
One of the objects of my invention is to produce .a material which has a-narrow plastic range and will stay hard approximately until it reaches its melting polnt, the material being also insoluble in solvent oils.
My invention relates more specifically to materials adapted for fillers for coils.
It is the practice in the construction of transformers to fill the spaces between the turns of the wire with a filler of some sort.
The transformer windings are then im-' mersed in insulating oil, preferably transil oil which is a petroleum oil of a highly insulating character used for transformers. The materials heretofore used and found to be suitable for transformer fillers have been soluble in the transil oil. I have [found that a compound of a wax like material such as 'carnauba wax with a gum, such as copal orv Specification o f Letters Patent, Patnted J an, 17, 1911,
Application filed August 7, 1907. Serial No. 387,508.
would have. have found that a compound consisting of substant-ially 75% of copal or kauri gum and 25% of carnauba wax produces a compound which in addition to being I compound is thus produced which is very efficient and is found to soak into the spaces 7 between the'windings very thoroughly.
While'I have described my compound as being composed of specific materials combined in definite proportions, it should be understood that I do not limit myinvention in these particulars except in so far as it is limited vby the scope of the claims annexed hereto. 7
What I claim as new and desire to secure by Letters Patent of the United States, is:
1. A compound composed of copal gum and carnauba wax.
2. A compound composed of substantially,
25% waxand 75% copal gum.
3. A compound composed of, substantially 25% carnauba wax and. 75% copal gum.
4. A filler for oil immersed transformer windings composed of substantially 25% wax and 75% copal gum.
' 5. A filler for oil immersed transformer windings composed .of wax and copal gum the latter constituting more than of the compound,
