New Catalog of Glass Insulators
Issued by Hemingray Company.
"The Hemingray Glass Co. has faithfully served for 78 years a wide range of customers. This long period of successful operation has been due to the maintenance of quality and service and the observance of good business principles." This paragraph is part of the foreword of a new catalog which the Hemingray Glass Co., Muncie, Ind., distributed this month.
It consists of 36 pages, descriptive of the glass insulators manufactured by this well-known company. The arrangement of the catalog is intended to give not only a clear and complete idea of the product, but also a general picture of the Hemingray plant, for it carries a series of pictures descriptively titled so that the recipient, in a manner, has an opportunity to visit the plant while sitting at his own desk.
Another feature of the catalog is the announcement of a new type of package for shipping the insulators, the use of which is optional with the company's standard barrel.
Photographs of the various types of insulators are reproduced, together with detailed diagrams, data, and shipping information. The reproduced photographs are printed in green ink, and closely resemble the color of the insulators. The catalog enumerates the pertinent requirements of good insulators, and emphasizes that the conclusions regarding glass insulators are not based on theory, but upon severe electrical tests employing standard methods and conditions, and lastly upon years of satisfactory service.
Special features which are stated to bein part responsible for glass insulators being today recognized standards for tele-phone and telegraph use, are given as follows:"
Transparency — exposes internal defects.
Homogenity — insures uniform insulating properties throughout each insulator.
Non-porosity — eliminates moisture ab-sorption. Sustains dielectric strength. Prevents deterioration.
Glass is easy to inspect.
Glass is unaffected by time or elements.
Glass, because it is manufactured of elements whose chemical components are known and can be controlled, is the same yesterday, today and tomorrow.
Glass insulators, reasonable in first cost and possessing all of the qualities required of good insulation, are the most practical and economical."
The factory of the Hemingray company at Muncie, Ind., is served by three main railroads, and a belt line giving two additional outlets. Emergency shipments are moved the same day the order is received. Routine orders are handled on approximately a ten-day basis.
Orders for Hemingray glass insulators, whether large or small, unexpected or steady, are promptly handled because adequate reserve stocks are maintained at the factory, precluding any delays or shortages on any of the types listed in the catalog.
Copies of the catalog will be sent to interested companies upon application to the Hemingray Glass Co., Muncie, Ind. A copy should be on file in every exchange.
