The Mt. Washington and Pairpoint Companies

The Patented Patterns (1887-1910)

This file is largely based on the J. Stanley Brothers, Jr. volumes of patented material at the Rakow Library of the Corning Museum of Glass and the U. S. Patent and Trademark Office's Web site. A composite catalog for The Pairpoint Corporation published by the American Cut Glass Association in co-operation with the Corning Museum of Glass, [1990], and the early work of Revi (1965, pp. 48-61) have also been useful.

It is not always easy to determine whether a patent issued during the 1870s was granted for an item's shape or for its pattern. This is the case for the first patented pattern listed here. Its specification, however, makes the patent's purpose unmistakable: "I am aware that glass vases having a bell or cone shape, and with flaring scalloped lips and longitudinal ribs, are not new, and I do not claim them. The distinctive character of my design is found in serrated and highly-polished ribs extending the length of the vase-body, the surface of which is ground off or lusterless." (Frederick S. Shirley) Prior to the discovery of this pattern's official name -- which is found in the c1885 MT. WASHINGTON GLASS CO. catalog (Padgett reprint) -- it was called "Polished Ribs" by collectors. The catalog also refers to the item as a 12" Ribbed Vase.

The name of the second patented pattern is given in an early catalog as Electric. It is often called "Angulated Ribbon", a name that apparently originated with Daniel (1950, p. 200) who lifted it from the patent specification. Revi, who had access to this early catalog -- which is apparently now lost -- also used the records of the U. S. Patent Office. As a result he mentions two additional patented patterns, Thurber and Dauntless, that were available at the time the Electric pattern was cut, but which are unknown today.

Revi also mentions other early patents, but they seem to be concerned with the shape of an item rather than any unique cut-glass pattern; therefore, these patents are not listed here. Of some interest, however, is his brief discussion of Frederick Shirley's design patent no. 16,172 of 14 Jul 1885, which was for a blank to be used for cutting:

The scalloped edge of the dishes [is] separated by deeply cut grooves which extend from the base of the bowl to the rim. Illustrations of these bowls in trade catalogues showing the company's cut glass wares indicate that the panels between the deeply cut grooves were ornamented by bright cuts in conventional designs, such as the "Russian", "Strawberry-Diamond", and "Old English Diamond" patterns (Revi 1965, pp. 51-52).

Appendix 1 of MT. WASHINGTON AND PAIRPOINT GLASS by K. M. Wilson (Vol. 1, 2005) provides lists of design patents and utility patents. The only patent for a cut-glass pattern listed there that is also listed below is design patent 18,595 (Mirror Block). Cut glass is treated only briefly in Vol. 1, presumably because there are plans to include the subject in Vol. 2.

All patents were assigned by their patentees to the companies, except those marked with an asterisk (*). These patents were retained by their patentees.
