Be sure and check out the other Items I have for sale thank you. For example, the three-groove socket design appears in catalogs at least until , so some additional information would be needed to distinguish a tool from the version. This ambiguity is still being investigated, and hopefully can be resolved to a satisfactory degree.
We can offer one example where additional catalog information proved sufficient to distinguish otherwise similar tools, as discussed with the ratchet adapter and ratchet adapter. Hopefully this date code interpretation will prove useful in its current form, but of course it's possible that later examples will require further revisions. The sockets shown up to this point have included a cross-hatched or knurled band, a stylistic hold-over from the days when a band of coarse knurling served as a hand grip.
In Blackhawk decided it was time for a makeover in socket style, and Sigmund Mandl developed a new socket design with three grooves around the base. Mandl filed a design patent for this three-groove socket style and received patent D, in The three-groove design went into production in late or early , and Blackhawk used this style for all of their sockets, except for the 1 inch drive size. Around this same time Mandl also filed a design patent for a tool handle with raised ribs, apparently as a "coordinating style" for the sockets, and examples of this "Gripline" handle style will be seen later.
All are marked "Made in U. These sockets have several features that collectively suggest that these are very early examples of the xx socket series. The first is the presence of the scalloped indentations in the drive ends, as shown in the inset. This feature was first seen in the 66xx series sockets, but is absent from most examples of the xx series. Most xx sockets show only a small chamfer at the drive end, as this was found to be sufficient for operation once the improved Lock-On slanted drive studs were in wide use.
Another detail is the large font size for the stamped model numbers; compare these to the other figures for xx series sockets. The rightmost socket also shows yet another marking oddity: the model number has been stamped incorrectly, as "" instead of "".
This suggests that perhaps the marking machinery was still being set up for the xx models, or possibly they were being stamped by hand. The last detail to note is that these sockets have no date code marked, a notable absence since most sockets of this style do show a date code. If the above reasoning has established that these are early examples of the xx series, the likely date of manufacture can be determined by a patent reference. The Blackhawk design patent for the three-groove socket design has been described above, and the patent D, was filed in early and issued in It's reasonable to assume that production of the sockets would have begun around the same time, making it likely that these sockets were manufactured in to early Date codes are known to have been marked on sockets by sometime in In Fig.
The inset shows the drive end indentations, indicating that this is another fairly early example of the xx series. However, unlike the previous examples, this one is marked with a date code of "9", visible in the photograph to the right of "Blackhawk".
The presence of both the indentations and date code is significant, as it means that the manufacturing date would have been , and the date code system must have started in the late s. This socket was very helpful in refining the interpretation of the date codes.
All are marked "U. RE 1,,". Note that the middle two sockets are finished with a thin and worn cadmium plating, and these two sockets both have a date code of "4". The righthand socket is chrome plated and has a date code of "1". The socket on the left is also chrome plated, but is an older model with no date code.
These details contributed to understanding the date code system explained earlier. The bottom socket is marked with a date code of "4" and has a cadmium finish, which is consistent with manufacture in The top socket is marked with a date code of "1" and is finished in polished chrome, consistent with manufacture in The base is stamped "Made in U.
The lower inset shows the broaching and construction details. Note that the inside has a stepped diameter to provide clearance and reduce the weight. The next several figures will show examples of the Blackhawk extension, a popular tool with a rotating hand grip.
We're fortunate to have acquired examples spanning a range of date codes and handle styles. The cross-bar hole has a detent ball to help secure the bar when in use, a convenience feature missing from modern tools.
The rotating hand grip on this tool has distinctive raised ribs along the axis, a style called "Gripline" in the Blackhawk catalogs. The Gripline style was based on the design patent D, , filed by Sigmund Mandl in and issued in Blackhawk used the Gripline style from about through , and we'll see numerous other examples of these handles in the figures that follow. No date code was marked on this tool, but several details will help to estimate the manufacturing date.
The Gripline handle indicates production in or late or later, based on the filing of the design patent. In addition, the drive end of the extension has scalloped indentations, a feature seen in the earlier xx series sockets.
Finally, the absence of a date code itself may indicate that the tool was made before the start of the coding system.
From these considerations, this extension was likely made in late or early RE 1,," patent notice. The rotating grip is in the Gripline style we saw in the previous example. The Gripline handle and "-3" date code on the tool indicate a manufacturing date of , which is consistent with the wartime manufacturing date suggested by the cadmium finish.
In Blackhawk changed its tool handles to a style with circular grooves instead of longitudinal ribs. An example of this later handle style is shown in Fig. The markings are very faint due to wear. The overall length is 5. The finish is chrome plating with losses due to wear. The left inset shows the cross-bar hole and detent ball in the drive end, making this tool highly functional as a T-handle.
The rotating grip is the Gripline style seen in some of the previous examples. The date code is marked "-1", which together with the Gripline style indicates a manufacturing date of The date code is marked "1" to indicate production in An additional code "FR" follows the date code digit, but the meaning of this marking is currently unknown. RE " and a "1" date code. The handle is the "Gripline" style with parallel ribs, and has a cross-bar hole for use as a Tee-handle.
In addition, the handle end has been drilled out for an extension bar. RE19, 1,," patent notice. The wide circular end-piece is also marked "U. The ratchet is marked with a "9" date code, which could indicate production in either or The reverse side has an "FR" code of currently unknown meaning. The ratchet is the successor to the Model and Q. Model X ratchets, and is in fact nearly identical to the later versions of the older models. The ratchet mechanism uses an tooth main gear and is fitted with a Lock-On drive stud.
The handle design is the "Gripline" style previously seen on several extensions, a style known to have been in use by The "2" date code and "Gripline" handle style indicate production in One notable detail for this ratchet is the very compact head, measured at only 1. The compact size is made possible by the ratchet mechanism described by patent 1,, , filed by E.
Pfauser and S. Mandl in and issued in This patent was also used for Blackhawk's ratchet adapters, such as the Blackhawk Ratchet Adapter shown in a later figure. One of the Blackhawk's notable innovations in drive tools was their development of practical and effective gearless ratchets, which they termed "Free-Wheeling" ratchets. The gearless designs were developed and patented beginning in with patent 1,, issued in , and later with patent 2,, , issued in RE ".
The left hand inset shows the date code of "-8", which together with the handle style indicates production in This is the currently our earliest date-coded example of the Gripline handle style.
The handle design is the "Gripline" style previously seen on several extensions, and this style is known to have been in use by The Gripline handle and "-2" date code indicate a manufacturing date of , which is consistent with wartime production suggested by the cadmium finish. The overall length is 2. The ratchet adapter is finished in polished chrome, and is marked with a date code of "-2", consistent with production in Of the four patents marked on the tool, patent 1,, covers the design of the basic ratchet mechanism.
The key innovation here was to place the ratchet gear in the body and let the pawl assembly rotate with the drive stud. This gave the gear a larger circumference and allowed more teeth for a finer action.
However, the later catalog No. The figure below will show an example of a later model with the larger diameter. The date code is marked as a "2", but as this adapter has the larger diameter specified in and later, the date code indicates a production date of This tool was helpful in confirming the extension of the date code system beyond This unit was disassembled for cleaning and lubrication, and the ratchet mechanism was noted as using two pawls in a symmetrical arrangement.
The earlier model has not yet been disassembled for comparison, but it may be that the increased body diameter was needed to allow the use of the stronger dual-pawl design. The "-5" date code indicates production in or , though the former date is probably more likely.
For the sockets, the change to the series was not merely cosmetic, as the socket design was changed from tapered walls to straight walls.
The change to the new numbering system appears to have taken place in , as a price list dated in April of includes a cross-reference of old and new numbers, and states that both numbers can be used for ordering in The insets show the date codes for the sockets, "3" on the left and "-6" for the right. The lefthand socket has a cadmium finish, which is consistent with a manufacturing date of The righthand socket is finished in polished chrome, which again is consistent with manufacture in These sockets contributed to the understanding of the date code system explained earlier, as the presence of a cadmium finish places the date of manufacture within the wartime years.
Both are marked "Made in U. RE 1,,", as expected for Lock-On sockets. The somewhat odd-looking inset in the photograph shows the markings and date codes for the sockets. The socket on the left has the standard polished chrome plating and a digit code of "-6", while the righthand socket has a thin cadmium plating and a digit code of "4". These sockets contributed to the understanding of the date code system explained earlier, and based on the codes were manufactured in and respectively.
The next two figures show examples of the model ratchet, the successor to the N ratchet. The face plate is stamped with the model and "U. RE ", followed by a "-9" date code and an "FR" notation, as shown in the middle inset. The handle has forged-in markings "Blackhawk Mfg. Milwaukee Wis. The "-9" date code indicates production in , as this ratchet model had been discontinued by or earlier.
This ratchet was acquired as part of a No. The meaning of the "FR" code following the date digit is not yet known, but has been observed on a number of Blackhawk tools. The lower inset shows a close-up of the "DIF" forging mark, a code used to indicate production by Interstate Drop Forge.
Interstate was a merchant drop-forging company in Milwaukee, established in and serving industrial customers as well as tool companies. Interstate Drop Forge also made some ratchet handles for Snap-On.
The forged flat handle is marked "Blackhawk Mfg. Milwaukee, Wis. RE " followed by a "-0 FR" code. The overall length is Most of the finish has been lost, but was originally chrome plating. The inset shows the date code marking "-0", which for this tool indicates production in This ratchet model had been discontinued by or earlier. An additional code "FR" follows the date code digit, a notation that has been observed on other Blackhawk tools as well.
This might stand for "Factory Reconditioned", but meaning is still uncertain. RE " patent notice. The Gripline handle is provided with a cross-bar hole, and in addition has been drilled out for use with an extension bar. The upper right inset shows the details of this construction. The Model extension was the successor to the T17XN model produced earlier.
This extension isn't marked with a date code, suggesting that it may have been made before the advent of the date code system. The socket is marked "Made in U. The socket is fitted with a Lock-On release button in the center, allowing an extension to be inserted and locked from either side. We haven't yet found a catalog reference for this tool, and it's possible that it might have been a special-order item. Without any other guidelines for the manufacturing date, the "9" date code could indicate production in either or The new 1 inch drive sockets and tools were given model numbers in an series, with 80xxx numbers for sockets and 89xxx number for drive tools.
The 1 inch drive tools used interchangeable handles to reduce the already considerable weight of these massive tools. The standard finish was cadmium plating. The finish on the socket is cadmium plating, which according to the catalogs was the standard finish for the 1-inch drive tools. The date code is "5", which could indicate production in or , but as the socket was acquired with other tools dating to the mid s, the likely manufacturing date is The ratchet mechanism uses a tooth gear and is covered by the same patent 1,, used by the ratchet adapters described above.
The pending status is for patent 2,, which was issued to S. Mandl in The ratchet has a stub handle designed to accept two types of handle extensions, a model bar that fits into the inner bore, or a model tubular handle that slids over the outside. In the former case, the lock button on the bar fits into the hole in the ratchet handle, and in the latter case, the lock button on the ratchet slips into a hole in the tubular handle.
In either configuration, the tubular extension and bar can be coupled together to provide even greater leverage. The bar also served as the handle for the ratchet head. The lower left inset shows the "-3" date code marking, which in this case could indicate production in either or , as cadmium finishes were standard for the 1 inch drive tools and sockets.
However, the ratchet acquired in the same lot had a patent pending notice that makes the likely production year. The righthand inset shows an end view of the tool, with the end broached for additional use as a short extension. The cross-bar hole is equipped with a detent ball to help hold the position on the bar. According to the Blackhawk sales literature, the enabling factor for these tools was the extra strength of the Hexite steel alloy developed by Blackhawk. This date had been somewhat uncertain for a while, but based on the date codes of collected examples, the tool series appeared to have originated in or early
