John H. Croskey

CROSKEY INSULATOR PATENTS SOLD

Now the Property of the Duquesne Glass

Company Which Will, It is Announced,

at Once Erect a Large Glass Plant.

In our issue of June 30th, we made reference in these columns to an automatic glass insulator machine, the invention of Mr. John H. Croskey, of this city, which was seen in practical, successful operation at the experimental glass plant of the H. L. Dixon Co. at Carnegie, Pa.

We learn that the patents covering this machine have been acquired by the Duquesne Glass Co., a corporation recently organized with a capital stock of $70,000, which proposes to at once build a plant and go extensively into the manufacture of glass insulators under the Croskey patents. It is said that over 65,000,000 insulators are used annually by the telephone, telegraph and electric light companies of this country, practically all of which are now manufactured by two concerns, and all by handworked presses. The Croskey method is as much ahead of the method of manufacture, as the nail machine of to-day is in advance of the method followed thirty years ago, so that the Duquesne company will have a very great advantage over its competitors in the business, by reason of its many advantages over the present method of manufacture. The company is at present using the plant of the H. L. Dixon Co., which is entirely inadequate to supply the demand for its goods. Offers of sites for the new factory are being considered and it is probable that the company will in short time decide its location, which will be in the Pittsburg district. Probably four machines, having a capacity of over 15,000,000 insulators per annum, will be first installed and additions will be made thereafter as fast as the demand warrants. The Duquesne Glass Co. is a close corporation and numbers among its stockholders men of wealth and high standing in the community.
