Expect to Manufacture Insulators, externally threaded insulators by Wheeling, W. VA party

EXPECT TO MANUFACTURE INSULATORS.

New Device to Be Introduced in the Market by Wheeling,

W. Va., Parties.

A Wheeling, W. Va., party has just secured letters patent on a glass insulator, to be used on telegraph and telephone poles, and which bids fair to supplant the old style device for this purpose.

The new device is a simple but ingenious invention. A model is now in the hands of Hesse & Kirchner of that city, who have purchased a third interest in the patent right. As is known, the old style insulator has a thread bore on the inside, and the size of the bore is about 1-1/4 inches in diameter. It has always been necessary to screw into this a short post which sets on the cross piece of the pole.

The new insulator, being also made entirely of glass, has a screw projecting out about 1-1/2 inches, which screws directly into the cross piece, thus doing away with the posts, which have been in use ever since the first insulator was invented.

The points of value more particularly claimed for the new device are that it can be manufactured for 1-1/2 cents each, and it can be sold for 3 cents. The work of putting them up is much less than the old style, and it is said they will be much more durable. In fact, in tests so far made it has been demonstrated to be stronger in every instance. When a thousand miles of wiring is taken into consideration, and in which no cross pieces will be necessary for the insulators, the saving will be something enormous.

It is understood that the formation of a company for the manufacture of the new insulators is on foot, and it is thought that Wheeling capital will be readily interested in the project.

Judging from the above description, the insulator is made along the same lines as that which was invented and patented by Thomas Blankinsop, the veteran Martin's Ferry, O., presser, who tried to introduce the new device four or five years ago.

A number of satisfactory tests were made at that time in Tiffin, O., and also in the Ohio valley, but for some reason, possibly on account of a shortage of finances, the invention was never pushed and its practicability thoroughly demonstrated.
