'To all whom it may concern;
Be, it known that I, KRI'srIAN PETTERSEN, a subject of the King of Norway, residing at Sarpsborg, Norway, have invented certain new and useful Improvements in Insulators with Fuses; "and I do hereby declare the following to be a ,'full, clear, and exact description of the invention, able others skilled in the art, to which it appertains, to make and use the'same, reference being had to the accompanying draw-- ings, and to letters or figures of reference marked thereon,
My invention relates to fuse-plug-insu- "to consists in inafter described and claimed,
In the accompanying drawings Figure 1 is a vertical section of theinsulator with elevation of hook and Fig. 2is a sectional elevation of the insulator.
The ,body of the insulator is provided with a hole a tending upward into the head of said insu': later. The hole a as well-asi the hook d is curved between the pointse and, L The hole a 'must be sufliciently large to a low for fixing (cementing) insulator to hook by h. Tosecure an elastic connection between hook and cementing substance a feature of importance in places with rough climate the part of the hook to be inserted in hole a should be wound with ribbons and soaked with shellac. Owing to the curved shape of the fixing hook a ver good setting of the'insulator obtaine samcneither being able to turn on the hook nor to slide off.
The contact ring'i for fixing the fuse plug to the lower part of the insulator is pro Specification of Letters Patent. Application filed May 2, 1912. Saris-1N0. 694,727.
