Carbon Steel Wrenches

Billings offered an extensive selection of carbon-steel open-end wrenches in a wide range of sizes. Although the wrenches were available in all of the industry-standard sizes, Billings used their own numbering system with 11xx model numbers, although at least some wrenches were stamped with their standard number equivalents.

In 1930 the 11xx wrenches were available in sizes ranging from the 1/4x5/16 model 1100A up to the 2-1/2x2-5/8 model 1159, the latter equivalent to the standard no. 49. (A cross-reference between the Billings and industry-standard sizes is available in our Table of Wrench Sizes.)

Billings continued to use their 11xx models long after most companies had adopted the industry-standard numbers, but eventually did convert to the standard numbering system. (The fact that the industry-standard models had been promulgated by arch-rival J.H. Williams may have been a factor.)

The standard markings for early Billings wrenches consisted of a raised forging of the B-Triangle logo on the shank, along with a stamped logo and text on one face. The text was typically "The Billings & Spencer Co." and "Hartford, Conn. U.S.A.", although abbreviations were used on some of the smaller wrenches. We'll refer to this combination as the "standard early markings", to avoid needless repetition in the descriptions below.

The markings for later wrenches went through several stages. The first change was the removal of the raised logo on the shank, allowing the wrench to be easily finished by grinding. Later changes simplified the company name to just "Billings", and added "Made in U.S.A." in place of the reference to Hartford. Where possible, we'll show multiple examples of each model to illustrate the marking changes.


Early Carbon Steel Wrenches

Billings offered carbon-steel wrenches in several model lines before the introduction of the well-known 11xx series wrenches. Currently we don't have much documentation for these early wrenches, but will show a few of the known examples. We hope to expand this section in the future.

The overall length is 4.5 inches, and the finish is black paint with polished faces.

The Billings model 1103 was the equivalent of the industry standard No. 22 wrench.


1104 3/8x7/16 Open-End Wrench

[Billings 1104 3/8x7/16 Open-End Wrench]

The reverse faces are marked "3/16 U.S.S." and "1/4 U.S.S.", both references to older U.S.S. size conventions. The model 1107 was the Billing equivalent of the industry standard No. 23 wrench.

One characteristic of the early Billings wrenches is that the edges typically retain the cutting marks where excess metal was trimmed after forging. The excess metal is termed "flashing", and a separate die was used to trim the flashing from the wrench body. Later Billings production added a grinding operation to provide smoothly rounded edges, and these wrenches show no trace of the trimming operation.


[Billings 1107 13/32x1/2 Open-End Wrench]
Fig. 34. Billings 1107 13/32x1/2 Open-End Wrench, ca. Mid 1920s.

Textile-Pattern Wrenches

Billings offered numerous models in a style called "Textile Wrenches", open-end wrenches with a 22.5 degree head offset, presumably originally intended for servicing looms and other textile machinery. This type of machinery often used square nuts, for which the 22.5 degree offset provided optimal access.

The examples below show a range of marking styles as the finishing techniques evolved over time. The earliest wrenches have a raised logo on the shank, with the shank retaining its natural forged finish and trimming marks. Later examples have smoothly ground contours on the shank and heads, with no trace of the trimming operation.

Within this later group, some wrenches have the older "Billings & Spencer Co." full marking on the face, but the latest examples have the "Billings Made in U.S.A." simplified mark.


1550 3/16x1/4 Textile-Pattern Open-End Wrench

We'll begin with an example believed to be the smallest of the textile wrench models.
