In 1893 the "drip point" patent was awarded to Ralph Hemingray and James C. Gill. James Gill was a mold maker for the company as early as 1884. By 1886 he was a foreman mold maker, moving to Muncie in 1890 as foreman of the mold shop there. The drip points, located on the bottom of the base of the insulator, were supposed to "take all the moisture from the inner and outer surface of the insulator and keep the pin dry", according to a company ad.

Robert Hemingray, founder of the company fifty years before, died in December of 1898. Ralph became president and another of Robert's sons, Robert Jr., became vice-president. A younger son, Daniel, became secretary-treasurer. (Daniel died in 1911). 

As the telegraph and telephone industries gained in importance in the late 1890's, the company began to concentrate more on the manufacture of insulators to better serve the increasing demands. The Hemingray Glass Co. soon became known the world over as the leading producer of glass insulators. Their insulators carried the company's name to most of the American continent as well as to almost every civilized country in the world. Insulators remained the mainstay of the company until the late 1920's (at which time bottle production was reinstated). 

By the early 1890's the Muncie plant had been expanded to the point where it was able to take care of the trade, and production at Covington ceased. According to the invoice reproduced on the following page and dated 1896, it appears that Covington remained for a time as a warehouse with some offices there also, while the main headquarters and factory were at Muncie. Covington was eventually closed, about 1919. (More on that later on). Also around 1898 to 1900 it is reported that the Hemingray Glass Co. had a sales office in St. Louis, Missouri. The exact location is unknown at this time, due to insufficient time for researching this information.

In 1901 Robert Hemingray Jr. died, and his brother-in-law, Bradford Shinkle, became vice-president. (This post was taken over by his son, A. C. Shinkle, about 1920).

In 1904 the Hemingray Glass Co. is listed in the directory as having three continuous tanks, with eighteen working rings and one day tank with six rings. A glassmaker explained this to me, saying that this refers to the number of hand workers around each tank of glass, and that "continuous" means that the furnaces were kept hot 24 hours, 7 days a week, and were only cooled down when repairs had to be made. This same year of 1904 saw the addition of a second furnace, called "B" furnace. These furnaces were huge affairs, the interiors of which were as large as some living rooms. (Both "A" and "B" furnaces still exist at the Muncie site).

"B" furnace, which is larger that "A" furnace, measures (inside) approximately 20 feet long by 16 feet wide by 15 feet high. The photos on the next two pages show the interior of "B" furnace, and were taken at various times over the years when it was shut down for repairs or renovation.

From 1904 issue of Telephony we read, "At the present time the claim is made that the Hemingray Glass Co. is not alone the largest establishment of its kind in the world, but that its yearly output and sales are more than those of all other insulator manufacturing industries combined. It manufactures annually many millions of insulators, all of which find a ready market. The factory at Muncie, Indiana, is kept running day and night, but even with the plant working to its outside limit, the company reports that it is behind in its orders. The offices of the concern, at Covington, Kentucky, are a busy hive of industry." It goes on to say that the company, more than any other agency, was particularly successful in producing superior high voltage insulators. 

In the 1910 Official Gazette of the United States Patent Office, a description of Hemingray's goods reads, "Electric, Telegraph, Telephone, Cable, Street-Railway, and Floor Insulators and Break-Knobs of Glass." And by about 1918 insulators had become the sole product of the Muncie plant.
