PAPER INSULATORS. — A not inconsiderable item of expense to the telegraph companies is the breakage of the common green glass insulators at present In universal use. Noticing a charge of $86,000 on this account on the books of a district superintendent of the Western Union in Indiana, a Cleveland gentleman was set to thinking and has since perfected a machine for making insulators of paper, with a capacity of turning out 6,000 a day. After being pressed to the desired shape, the insulators are treated to a coat of tar, asbestos, etc. Of course they are un breakable. We understand that the telegraph companies are eager to get hold of the new invention, and that, the company at present supplying the glass insulators has offered a large sum for patent. — Iron Trade Review.
