Database Home Hemingray used mold letters, dome numbers, and even oddly placed periods in some of their earlier insulators to denote which mold an insulator was produced from. However, it wasn’t until , when Hemingray was purchased by Owens-Illinois, that they began embossing their insulators with specific mold and date codes. Many different codes were used over the years, and I will attempt to explain them all here in relative order. All known specimens are Ice Blue in color. The “4” is believed to signify In this example, “12” is the mold number.

Whitall entered the business in partnership with G. Haverstick and William Scattergood. Whitall Tatum produced very large quantities of bottles and fruit jars throughout much of the mid- and late 19th century. Pharmacy, druggist, barber, perfume, chemical and other types of bottles in various colors and styles were produced, and some of them are now avidly sought by antique bottle collectors.

Less commonly-seen are examples found in a beautiful rich teal green glass, as well as cobalt blue. See this page on Artificially Purpled Glass.

It should be noted that features 1, 3, 4, 5, and 6 are primary indicators of machine-made manufacture. Feature 2 mold seam diameter is not as strongly diagnostic as the primary indicators as mouth-blown bottles sometimes can have very fine mold seams.

Feature 7 describes a couple glass related features that are quite consistent in machine-made bottles, but not diagnostic, i. Click on the machine-made beer bottle picture above to see an illustration of this bottle showing the major diagnostic characteristics of a typical machine produced bottle. Vertical side mold seams which usually see the Note box below point 3 for an exception run up to the highest point of the finish and often onto the extreme top finish surface i.

The statement about machine-made bottles may seem contradictory finer but more visually distinct but is a function of the higher machine blowing pressure. Most machine-made bottles have mold seams about the thickness of a hair while most visible mouth-blown mold seams tend to be several times as thick, higher, but more rounded.

Before electricity was made, there was the Big Electricity to deal with: So, the earliest glass insulators were LRIs Lightning Rod Insulators , used to insulate lightning rods and cables from structures. They date to the s or earlier, and were made in glass until about the turn of the century. To produce the current needed, wet cell DC batteries were used: These batteries were often insulated from their supports with “battery rest insulators”. See Richard Dawson’s display for more. The early years of telegraph development saw rapid change in insulator design: Many designs were fine when first installed usually during mild, dry weather , but failed quickly in the wet season, or became damaged due to big temperature swings.

The insulator was glued to the pin with molten sulphur, tar, burlap, etc, and the pin set in a hole in a crossarm. Since the pin-hole was plain and smooth, these are called “threadless”. The problem was the glueing: The insulators would work loose, and in cold weather when the line wire shrank, would pop off the pins. In Louis Cauvet patented the idea of threading both the pin-hole and pin, thus securing the insulator.

Pin insulator Insulator of a telephone transmission line A pin insulator consists of a non-conducting material such as porcelain, glass, plastic, polymer, or wood that is formed into a shape that will isolate a wire from a physical support or “pin” on a telegraph , utility pole or other structure, providing a means to hold the insulator to the pin and secure the conductor to the insulator. Unlike a strain insulator , the pin insulator is directly connected to the supporting pole. Pin insulators were utilized before , pre-dating the strain insulator.

Production of pin insulators is continued today by manufacturers worldwide. The pin insulator is designed to allow the conductor to be readily secured to avoid it coming adrift. The most common method is to use a wire to tie the conductor to the insulator. Another method is to provide self-fixing features such as complex slots and grooves formed into the insulator. For heavy conductors, gravity can be used to help hold the conductor in place. Pin insulators are almost always deployed in the open air, so isolation when wet is a major consideration.

To combat this problem they have smooth surfaces and deep skirts or wide shells.

Although best known for their electrical insulators, Hemingray also produced many other glass items, including bottles, fruit jars, pressed glass dishes, tumblers, battery jars, fishbowls, lantern globes, oil lamps, and much, much more. Hemingray began as a small operation in Cincinnati in The exact year when actual insulator production ended at the Covington site is still undetermined, but it was likely sometime in the period.

The Covington factory also re-opened for a short time in the period. The business offices remained at Covington until , at which time all operation was moved to Muncie. Date codes were embossed on most insulators made after , and the majority but certainly not all of post production was made in clear colorless or off-clear glass. The very last glass insulators made were produced at the Indiana Glass Company factory located in Dunkirk, Indiana, using molds that had been moved from Muncie to that location.

Lightning rod insulators, and various sizes of spool insulators were also made. The earliest Hemingray s have sharp drip points, which are believed to have been phased out approximately or The transition to off-clear glass began approximately Typically, the first number before the dash represents the mold number, the second number s , after the dash, indicates the year the mold itself was made. However, not all 42s have this type of date code, especially some of the earlier units dating between For more information, please see a query I received which is posted near the bottom of this page.

Using differential calculus, he characterized the intrinsic properties of curves and surfaces. For instance, he showed that the intrinsic curvature of a cylinder is the same as that of a plane, as can be seen by cutting a cylinder along its axis and flattening, but not the same as that of a sphere, which cannot be flattened without distortion. The first notable attempt to reorganize the study of geometry was made by the German mathematician Felix Klein and published at Erlangen in
