Introduction

Snap-on Tools is one of the largest and best known makers of hand tools today. This article will look at the development of the company during the 1920s, covering its first ten years of operations.

The later development of the company will be covered in our article on the Snap-on Tools Corporation.

Company History

The Snap-On Wrench Company was founded in 1920 by Joseph Johnson and William Seidemann, with its initial location at 134 Reed Street in Milwaukee, Wisconsin. The company's founding principle was the superiority of interchangeable socket tools over fixed (or "tight") socket wrenches, and their first product was a modest collection of five drive handles and ten sockets.

Prior Experience

Johnson and Seidemann had previously worked at Blackhawk Manufacturing and its parent company American Grinder, and in particular Johnson had been the manager of Blackhawk Manufacturing.

While at Blackhawk, Johnson had overseen the introduction of a ground-breaking line of interchangeable socket tools based on machined and broached sockets with 1/2 square drive.

Blackhawk began offering its socket tools in May of 1919, with the initial line including five models of interchangeable socket sets.

The scan in Fig. 1 shows an early advertisement for Blackhawk socket sets, as published on page 113 [External Link] of the June 19, 1919 issue of Motor Age magazine.

The illustration shows all five models of Blackhawk's early socket sets, along with a display board of fixed socket wrenches for Ford service.

Incorporation in 1920

After leaving Blackhawk and American Grinder, Johnson and Seidemann moved quickly to set up and incorporate their new business.

Fig. 2 shows a small notice of the company's incorporation, as published on page 1215 of the April 22, 1920 issue of Iron Age.

The text notes the capital stock as $25,000 and identifies the company's attorney as J.N. Marshutz. Somewhat oddly, this notice doesn't mention the founders or provide the company address.

The illustration shows the five handles and ten sockets that made up the company's first product, referred to as a "General Service" set here.

The text notes that the collection would make up 50 wrenches, which was sometimes summarized in a "5 Do the Work of 50" catch phrase.

Fig. 5 shows a slightly later notice, published on page 76 of the January 1, 1921 issue of the Automobile Trade Journal, which nicely summarizes the tools available from Snap-On Wrench at that time.

Notice the display board at the top right with the "5 do the work of 50" slogan.

A similar notice (but without the display board illustration) was published on page 64 of the February 15, 1921 issue of the Commercial Car Journal.

The Motor Tool Specialty Company

The Blue Point Tool Company

As their business grew and customers began requesting other types of tools, Snap-On decided to establish a second line of tools to meet the demand. By September 15, 1923 the Blue Point Tool Company had been formed in Chicago and the name "Blue Point" was being marked on tools.

The founding date comes from the first use date listed on a 1929 trademark application for "Blue Point", which listed the company address as 14 East Jackson Street in Chicago. (Blue Point Tool seems to have shared the address of Snap-On's distribution company, the Motor Tool Specialty Company of Chicago.) Joseph Johnson signed the trademark application as the Treasurer for the company.

In the beginning Blue Point relied primarily on outside contractors to produce tools to its specifications, using the production facilities of various tool companies in Chicago and other areas. Establishing the identity of these contract companies would be of considerable historical interest, but this has proven to be difficult for various reasons.

At the present time only two companies have been identified as early producers for Blue Point: the Forged Steel Products Company of Newport, Pennsylvania, and Milwaukee Tool & Forge (MTF) of South Milwaukee, Wisconsin.

The former company is the well-known maker of "Vacuum Grip" pliers sold by Snap-On, but also supplied forging facilities for production of Blue Point tools in the mid 1920s. The latter company can be identified by a tool roll naming MTF as the maker of "Milwaukee Blue Points" tools for the Motor Tool Specialty Company, as well as catalogs listing both MTF and Blue Point.

By 1926 a wide variety of tools were being offered under the Blue Point name, including wrenches, chisels, punches, hammers, and specialty tools. "Boxocket" box-end wrenches followed in 1927, and new styles of obstruction and ignition wrenches were introduced in 1928.

Blue Point or Blue Points?

Although the catalogs called them "Blue Point" tools, they also showed a logo with the wording "Blue Points Chicago" between two pointed arrows. Apparently some of their contract manufacturers took this literally and marked the tools with "Blue Points" or "Blue Points Chicago", sometimes with the arrow logos. Eventually the naming was decided in favor of plain "Blue Point", but some Blue Point tools were still being marked "Blue Points Chicago" possibly as late as 1929.

Trademarks

The table below lists the various trademarks registered by the Snap-On Wrench Company (or its Blue Point subsidiary) during the 1920s. The entries are presented in order of the registration number.

The first entry in the table seems to have a curious status, as it has "disappeared" from the USPTO "TDR" database, which usually has an entry even for very old trademarks.

Fig. 6 shows the information for trademark #147,515 as it was published on page 667 of the October 18, 1921 issue of the USPTO Official Gazette.

Note that the first use date is claimed as February 2, 1920 — preceding the company's incorporation date.

Tool Identification

Snap-On tools are generally clearly marked and consistently numbered, but the tools from the 1920s are the exception to this rule. These early tools were marked in several different styles, or not marked at all, making it somewhat tricky to identify them. This article will look at some examples of early Snap-On tools with different marking styles. and will attempt to develop guidelines for estimating the date of manufacture.

Manufacturing Dates

Beginning in 1927 Snap-On introduced a system of date codes and started marking sockets (and other tools as well) with the codes. The date code was generally a single digit (later, a symbol or character) to indicate the year of production, with the digit sometimes preceded or followed by a dash. For 1927 through 1930 the system was very simple: one of the digits 7, 8, 9, or 0 indicated the year. In later years though, symbols and script styles were added in order to extend the system, and you'll need to consult a date code chart to determine the date. Date codes were applied in 1927 and later without regard for the socket marking style.

In its early years the date code system had a very specific function: tool warranties were of limited duration at the time, and the date code determined the start of the warranty period. As a result, date codes were applied more consistently at this time than in later years, after Snap-On had started offering a lifetime guarantee on its tools.

Catalog Coverage

Product information was obtained from catalogs from Snap-On and the Motor Tool Specialty Company, as noted in the table below.

Early Snap-On Sockets

The first sockets offered in 1920 were available in 1/2 (square) drive only, and were broached for either single-hex (6-point) or single-square (4-point) openings. Additional drive sizes were offered later, 5/8-drive in 1923, 7/8-drive around 1924, 9/32-drive in 1925, and finally 3/8-drive in 1928. Double-hex (12-point) and double-square (8-point) broachings were introduced in 1927.

The very earliest socket markings were certainly minimal: according to folklore, the first Snap-On sockets (and drive tools) had only size markings, or no markings at all! Such sockets would be difficult to identify and authenticate if found, but could be compared to known marked examples for an indication of possible Snap-On origin.

The earliest standardized marking for sockets consisted of an "S" and "O" overstrike to indicate Snap-On, together with the socket size in fractional notation. (The size marking was usually on the opposite side from the S/O-Overstrike.) This marking style was used up until about 1923.

Around 1924 Snap-On began marking sockets with their full logo instead of the S/O-overstrike. Snap-On also introduced a socket numbering system at about the same time, which consisted of the abbreviation "NO." followed by the model number, a variation on the size expressed in 32nds. For example, a 1/2-drive 6-point socket of size 7/8 was marked "NO. 280", the "28" being derived from the 28/32 size. Sockets marked in this fashion will have the model number, Snap-On logo, and fractional size, all on the same side of the socket.

The above numbering scheme was simple and useful, but apparently it was not implemented consistently, as some sockets continued to be marked with only the Snap-On logo and fractional size. This state of affairs wasn't just a temporary delay in adding the model numbers, but persisted through to the end of the 1920s, so that examples of both styles can be found with late date codes.

As a result of these changes, we can recognize three basic marking styles for the early sockets: the S/O-Overstrike, the marked but un-numbered sockets, and the model-numbered sockets. Even this is a bit of an oversimplification; in a large collection of early sockets, there may be a number of other recognizable changes in design and marking.
