Introduction

The Peck, Stow, & Wilcox Company was an important manufacturer of tools and machinery in the latter 19th and early 20th centuries.


Company History

The Peck, Stow, & Wilcox Company was organized in 1870 by a three-way merger of the Peck, Smith Manufacturing Company, the S. Stow Manufacturing Company, and the Roys & Wilcox Company. In 1880 the company was chartered by an act of the Connecticut legislature.

Information on the earlier history of the company can be found on page 333 of the Nineteenth Annual Report of the Bureau of Labor Statistics for Connecticut, published in 1903 and included as part of the Public Documents of the State of Connecticut.

A 1901 Manual of Statistics notes that the company made tinner's machinery, tools, and household utensils. The 1901 sales were listed as $1,152,000.

Wrenches


Pexto "Solid Bar" Monkey Wrench

Our first figure shows an interesting early example of a patented "monkey" wrench produced by Pexto.

[Pexto Solid Bar Monkey Wrench]
Fig. 1. Pexto "Solid Bar" Monkey Wrench, ca. 1900.

In Fig. 1 we see a Pexto "Solid Bar" adjustable wrench, marked "P.S.W. & Co." and "Made in U.S.A." with the patent date "Pat. Jan 14, 1896". The overall length is 6.5 inches.

The corresponding patent was found to be #553,059, issued to R.C. Ellrich with assignment to the Peck, Stow, & Wilcox Company. The patent describes a novel construction technique whereby the fixed jaw can be made integral with the shaft and handle, instead of being added after assembling the sliding jaw. The trick to the assembly is that the sliding jaw has slits in the back, allowing it to be spread open for installation over the shaft.


Pexto 8 Inch Stillson Pattern Pipe Wrench

[Pexto 8 Inch Stillson-Pattern Pipe Wrench]
Fig. 2. Pexto 8 Inch Stillson-Pattern Pipe Wrench, with Inset for Side View.

Fig. 2 shows a Pexto 8 inch pipe wrench of the Stillson design, marked "Made in U.S.A." with the PEXTO-Oval logo.

The overall length is 7.0 inches.

The original Stillson pipe wrench design is described by patent #95,744, issued to Daniel Stillson in 1869 and arguably one of the most famous tool patents of all time. The Stillson pipe wrench was highly successful for its maker (Walworth) and generated a small fortune in royalties for the inventor, a fact that probably encouraged generations of later inventors to develop their ideas.

Stillson pipe wrenches were produced by a wide range of manufacturers after the patent expired, and many of these continued to be marked "Stillson" or "Stillson Pattern".
