Variability in "Blue Point" Markings

Although Blue Point Tool registered only one "BLUE POINT" trademark in the 1920s -- the trademark #270,479 showing "BLUE POINT" with two arrowheads -- the brand markings actually used on tools show a fair degree of variability. Beginning in the 1920s, the markings "Blue Point", "Blue-Point", "Blue Points", and "Blue Points-Chicago" were regularly used, sometimes with the arrowhead symbols, but other times just as text. Both block letters and script forms were used.

From the 1930s through the 1950s, forms more commonly used were "Blue Point" or "Blue-Point", sometimes followed by "Boxocket" or "Supreme" as a secondary trademark. In order to recognize the variability in usage, this article will report the brand using the form closest to the marking on the tool, with the understanding that all of these marks refer to the earlier "BLUE POINT" trademark. (The #270,459 registration was renewed in 1950, giving it coverage over the full nominal period of this article.)


Manufacturing Dates

The date code system established by Snap-on in 1927 was further extended during the following decades. The first few years of the 1930s used several odd symbols, but by 1934 the date codes had been standardized on the use of stylized numeric digits. In this arrangement each decade was given a particular "theme", with the digits transformed according to the theme. For example, during the 1950s the numbers had rounded tops or bottoms, or both.

Snap-on peridiodically published charts of its date code system, and scans of the chart are widely available online. The actual stamped symbols sometimes vary from the idealized form shown in the charts, and for this reason it's helpful to study the actual markings. At some point we'll provide a table of "As Used" date code markings.


Blue Point Wrenches

Boxocket Box-End Wrenches

Blue Point had offered box wrenches since the 1920s in two styles, the long single-offset and short double-offset models. During the 1930s the selection of box wrenches expanded significantly, first with addition of the XD-series of angled box wrenches, then later with the X-series of long double-offset wrenches.

The figures below will explore all of these styles, beginning with the single-offset wrenches.


Single-Offset Box Wrenches

Blue Point introduced the X series of single-offset box wrenches in 1927, and these models were among the first double-box wrenches available from any vendor. The X-series wrenches continued in production into the 1930s, with one additional model (X-30) being added during this period. But toward the end of the decade this style had fallen out of favor, and the series was discontinued by 1939.

Blue Point Open-End Wrenches

Blue Point first offered open-end wrenches in the mid 1920s with a line of "Number Series" models, e.g. model No. 1922 for a 19/32 by 11/16 wrench. This series continued into the 1930s as the primary line of open-ended wrenches, at least until the 1935 introduction of the Blue-Point "Supreme" line.

Blue-Point Supreme Open-End Wrenches

In 1935 Snap-on introduced a new line of open-end wrenches under the "Blue-Point Supreme" name. According to the 1935 Snap-on catalog, the new wrenches were made possible by the development of a high-carbon alloy steel, which allowed a thinner and lighter design without compromising strength.

The early production of the Supreme wrenches had the shank ground after forging, with the sides tapering to a flat strip in the center. The flat strip was used for the marking "Blue-Point Supreme" (and possibly a date code), and the wrenches were finished with nickel plating.

This ground-shank style was soon superseded; by 1937 the Blue-Point Supreme wrenches were using a forged design with a raised rib in the center. The top of the rib was then ground and polished, and the sides were left with their natural forged finish. By this time the standard finish had become plated chrome.

The table below summarizes the Blue-Point Supreme open-end wrench models, and one of the columns reports the earliest year of production, based on catalog listings or known examples. (Our catalog coverage is a bit uneven though, so it will take some time to refine the table.)

[Blue-Point Supreme S-4854 1-1/2x1-11/16 Open-End Wrench]

Fig. 78C shows a Blue-Point S-4854 1-1/2x1-11/16 open-end wrench, stamped with "Supreme" and "Made in U.S.A." on the raised rib.

This wrench is not marked with a date code, but the slightly raised rib and chrome plating suggest a production date in the late 1930s.

The size combinations on this wrench are unusual, and currently no catalog reference for this model has been found. A close look at the model number shows that the final "4" is stamped over a "2", indicating that this is likely a special order tool made by replacing the 1-5/8 opening of an S-4852 Wrench with 1-11/16.


Tappet Wrenches

The Blue-Point Supreme line extended to tappet wrenches as well, and the next set of figures will show examples.


Blue-Point Supreme ST-1614 Tappet Wrench

[Blue-Point Supreme ST-1614 7/16x1/2 Tappet Wrench]
Fig. 79. Blue-Point Supreme ST-1614 7/16x1/2 Tappet Wrench, ca. 1935-1938.

The overall length is 7.8 inches, and the finish is nickel plating, with some loss due to wear and rust.

This example is not marked with a date code, but the ground shank indicates production in the years 1935-1938.


Blue-Point Supreme ST-1816 Tappet Wrench

[Blue-Point Supreme ST-1816 1/2x9/16 Tappet Wrench]
Fig. 80. Blue-Point Supreme ST-1816 1/2x9/16 Tappet Wrench, 1938.

Fig. 80 shows a Blue-Point ST-1816 1/2x9/16 tappet wrench, stamped "Supreme" on the shank with a date code of "8-" for 1938.

The overall length is 8.0 inches, and the finish is nickel plating, with some loss due to wear and rust.

The date code initially posed a bit of a mystery here, as the digit style (and trailing dash) suggested manufacturing during the 1920s. However, this style of tappet wrench doesn't appear in the catalogs until the mid 1930s, and the construction style of this wrench is consistent with production in 1935-1938. Hence the "8-" date code likely indicates a manufacturing date of 1938.


Blue-Point Supreme LST-1816 Long Tappet Wrench

Blue Point also offered tappet wrenches in a long format LST series.

[Blue-Point Supreme LST-1816 1/2x9/16 Long Tappet Wrench]

Blue-Point Supreme LTA-1618 Long Tappet Wrenches

In later years Blue Point adopted a simplified design for its tappet wrenches using equal offsets for both ends, thereby obviating the need for paired models. The next figures show two generations of the Blue-Point LTA1618 model.

[Blue-Point Supreme LTA-1618 1/2x9/16 Long Tappet Wrench]
Fig. 82. Blue-Point Supreme LTA-1618 1/2x9/16 Long Tappet Wrench, 1937.

Waterpump Wrenches

Blue Point's distinctive "water pump" wrenches were introduced in an earlier article, and the reader may want to check the section on Bluepoint Waterpump Wrenches for additional examples.

The waterpump wrenches are generally marked with either "Patent Appl'd For" or "Patd. Re. No. 17417" forged into the shank, although sometimes the second notice is stamped on the back. Normally when a patent applied (or equivalent) notice is marked on a tool, we would expect the production date to lie between the filing and issue dates of the patent. However, estimating the manufacturing date for the waterpump wrenches has turned out to be a bit more difficult than expected.

The problem is that Blue Point appears to have continued using the "Patent Appl'd" forging dies for long after the patent was issued, possibly because the production volume was relatively low and the dies didn't wear out.

Blue Point 924 3/4 Waterpump Wrench

[Blue Point 924 3/4 Waterpump Wrench]
Fig. 94. Blue Point 924 3/4 Waterpump Wrench, ca. Early 1930s.

Fig. 94 shows a Blue Point 924 3/4 waterpump wrench, marked with "Patent Appld For" and "Blue Point Boxocket Chicago Ill" forged into the handle.

The overall length is 6.5 inches, and the finish is plain steel with traces of cadmium plating.

The patent application notice refers to the (reissue) patent #RE17,417, issued in 1929 and assigned to Blue Point. (The original patent #1,626,809 had been issued to B. Gillett in 1927.)

Blue Point 928 7/8 Waterpump Wrench

[Blue Point 928 7/8 Waterpump Wrench]
Fig. 95. Blue Point 928 7/8 Waterpump Wrench, with Inset for Reverse Detail, 1931.

Fig. 95 shows a Blue Point 928 7/8 waterpump wrench, with forged-in markings "Patent Appld For" and "Blue Point Boxocket Chicago Ill", but with the "Blue Point" and "Chicago" removed by grinding. The reverse is stamped with "-29" and "*" date codes for 1929 and 1931 respectively.

The overall length is 6.5 inches, and the finish is cadmium plating.

This example has a narrow handle with an approximately rectangular depressed panel in the shank. The narrow-handle style appears to have been used for the early production of all of the smaller sizes, with a single forging blank serving for sizes 3/4 up to 1-1/8 inch.

Blue Point 932 1 Inch Waterpump Wrench

The next figures show examples of the Blue Point 932 model, but made with different forging dies.

[Blue Point 932 1 Inch Waterpump Wrench]
Fig. 96. Blue Point 932 1 Inch Waterpump Wrench, ca. 1932+.

Fig. 96 shows a Blue Point 932 1 inch waterpump wrench, marked with "Patent Appl'd" and "Blue Point Boxocket Chicago Ill" forged into the handle.

The overall length is 6.9 inches, and the finish is chrome plating with polished faces.

This example was made from an older forging with the patent applied notice for patent #RE17,417. The chrome plating and polished faces indicate later production, so the finished wrench was likely made from a blank forged some years before.

[Blue Point 932 1 Inch Waterpump Wrench]
Fig. 97. Blue Point 932 1 Inch Waterpump Wrench, ca. Mid 1930s.

Fig. 97 shows a later Blue Point 932 waterpump wrench, marked with "Patd Re No 17417" and "Blue Point Boxocket Chicago Ill" forged into the handle. The reverse is also stamped "Chev 36" (not shown), probably referring to a specific application.

The overall length is 6.4 inches, and the finish is polished steel.

The patent number forged into the handle indicates that the forging dies for this example were updated sometime after the 1929 reissue date for patent #RE17,417. Blue Point is known to have used its earlier forging dies for long after the patent date, so this example is probably from the mid 1930s.

Note also that the handle has a factory-installed hanging hole, a feature believed to indicate later production, though not specifically noted in the catalogs.

Blue Point 936 1-1/8 Inch Waterpump Wrench

[Blue Point 936 1-1/8 Waterpump Wrench]
Fig. 98. Blue Point 936 1-1/8 Waterpump Wrench, ca. Early 1930s.

Fig. 98 shows a Blue Point 936 1-1/8 inch waterpump wrench, with forged-in markings "Patent Appld For" and "Blue Point Boxocket Chicago Ill" on the shank. The reverse is stamped "Pat. Re. No. 17,417" and "C-1", with the latter possibly a special application-specific model number.

The overall length is 6.5 inches, and the finish is cadmium plating.

This example has a narrow handle similar to previous examples.


Blue Point 938 1-3/16 Waterpump Wrench

[Blue Point 938 1-3/16 Waterpump Wrench]
Fig. 99A. Blue Point 938 1-3/16 Waterpump Wrench, with Inset for Reverse Detail, ca. Mid 1930s.

Fig. 99A shows a Blue Point 938 1-3/16 waterpump wrench, marked with "Patd Re No 17417" and "Blue Point Boxocket Chicago Ill" forged into the handle, with a "9-2" code forged into the reverse.

The overall length is 7.0 inches, and the finish is chrome plating.

Note also that the handle has a factory-installed hanging hole, a feature believed to indicate later production, though not specifically noted in the catalogs.

A similar but somewhat earlier example of this model can be seen as the Bluepoint 938 Waterpump Wrench.


Blue Point 940 1-1/4 Waterpump Wrench

[Blue Point 940 1-1/4 Waterpump Wrench]
Fig. 99B. Blue Point 940 1-1/4 Waterpump Wrench, with Inset for Reverse Detail, ca. Early 1930s.

Fig. 99B shows a Blue Point 940 1-1/4 waterpump wrench, with forged-in markings "Patent Appl'd" and "Blue Point Boxocket Chicago Ill" on the shank, and stamped "Pat. Re. No. 17,417" on the reverse (see inset).

The overall length is 7.0 inches, and the finish is plain steel.

This wrench is very similar to the Bluepoint 940 Waterpump Wrench shown in an earlier article. The present example has been finished with a grinding or sanding operation and is marked with the patent notice, indicating a later production date.


Blue Point 942 1-5/16 Waterpump Wrench

[Blue Point 942 1-5/16 Waterpump Wrench]

Fig. 100 shows a Blue Point 942 1-5/16 waterpump wrench, stamped with the model and size near the opening, with "Patent Appl'd" and "Blue Point Boxocket Chicago Ill" forged into a depressed panel on the shank.

The overall length is 7.0 inches, and the finish is cadmium plating with polished faces.


Blue Point 944 1-3/8 Waterpump Wrench

[Blue Point 944 1-3/8 Waterpump Wrench]
Fig. 101. Blue Point 944 1-3/8 Waterpump Wrench, with Inset for Reverse Detail, 1935.

Fig. 101 shows a Blue Point 944 1-3/8 waterpump wrench, stamped with the model and size near the opening. The shank has a depressed panel area with forged-in markings "Blue Point Boxocket" flanked by "Patent Appl'd For" and "Chicago Ill" on either side.

The overall length is 7.6 inches, and the finish is chrome plating with polished faces.

The reverse has multiple date code stampings, with a stylized "5" for 1935 at the left and the 1931 asterisk symbol "*" at the right. It's somewhat unusual to have multiple date codes separated in time by several years, but one possible explanation is that the wrench was originally forged in 1931, then remanufactured with a chrome finish in 1935.

The patent applied marking refers to the Gillett 1929 reissue patent #RE17,417, although this example was made well after the issue date.


Blue Point 948 Waterpump Wrench

[Blue Point 948 1-1/2 Waterpump Wrench]

The overall length is 8.2 inches, and the finish is cadmium plating.


Combination Wrenches

Combination wrenches were first introduced in the 1935 Snap-on catalog, which offered both short- and long-handled models in a limited selection of sizes. The initial selection included five short wrenches, with sizes from the 7/16 OEX-140 model up to the 11/16 OEX-220 model, and three standard (long) wrenches in sizes 1/2 (OEX-16), 9/16 (OEX-18), and 5/8 (OEX-20).

Combination wrenches proved to be very popular and the selection was soon expanded.

The overall length is 5.6 inches. The finish is chrome plating, but with significant losses due to rust and pitting.

Although no date code was found on this wrench, the production date can be estimated as 1937-1939 based in the stamped markings without a "Made in U.S.A." notation.

[Blue Point OEX-160 1/2 Short Combination Wrench]
Fig. 106. Blue Point OEX-160 1/2 Short Combination Wrench, 1942.

Fig. 106 at the left shows a somewhat later Blue Point OEX-160 1/2 short combination wrench, stamped "Blue Point" and "Made in U.S.A." on the shank, and with a stylized "2" date code for 1942 on the reverse face.

The overall length is 6.7 inches, and the finish is chrome plating.

This wrench is significant as one of the earliest examples with a fully polished shank and stamped markings. Other examples show that the forged-in markings continued into 1937, suggesting that 1937 was the transition year for stamped markings.
