Herbrand tools wiki

Dad's the III. Nothing from my dad's grand dad was passed down at all, except the first, middle, and last name, and that everyone since has been in the military for a spell. Grand dad and I went Navy, dad went Army. Thanks for the note, I hope you look around my blog and enjoy the other tool and tool box posts, and the other fun stuff. Saturday, January 20, Herbrand tools Bonney history merged with them, as smaller tool companies couldn't compete with less expensive imported lower quality tools.

Labels: informative , tools. Marc B AM. Jesse AM. Unknown PM. Jesse PM. Unknown AM. According to the catalog, the No. These pliers remained in production for a number of years, and were still available in the catalog.

The catalog includes a "Patent Applied For" notice in the description for these pliers, but the corresponding patent if issued has not been found. The wrench is stamped "Made in U. This wrench features two hex openings, each stepped to provide two sizes, plus three 8-point openings. The catalog lists this tool for adjusting Bendix internal brakes. This wrench is listed in the Herbrand catalog M from around , where it is described as an "Extra Long" wrench for servicing anchor nuts on Bendix and other mechanical brakes.

This tool was designed as a brake bleeder wrench, and the hex sockets have a hole drilled to allow air and brake fluid to escape. This tool is listed in a Herbrand catalog, but not in the catalog, so it was apparently developed at a later point. Herbrand was known to recycle its model numbers on occasion, and their catalogs from the s and s have model assigned to a brake pedal depresser. During the late s and early s, the "Steeldraulic" brand of mechanical brakes were used on several makes of automobiles, for example the Hupmobile.

These brakes had an adjustment mechanism in an awkward position, and required a special type of pliers to make the adjustment. The overall length is 5. The pliers have a heavy nickel plating, with a satin finish on the handles and polished in the jaw area.

A number of other companies also made Steeldraulic pliers, all similar in the design of the jaws as required by the application , but with some variation in the handles. The Herbrand catalog M lists this tool for Hudson and Essex service in the and model years, and also recommends it for Plymouth transmission plugs. Herbrand offered several models of double-box wrenches with a half-moon or elbow shape, typically designed for servicing starter or manifold nuts, or other operations in tight places.

The next several figures show examples of these wrenches. The inset shows the "" code forged into the reverse side, indicating the use of AISI steel. This steel is a triple alloy of nickel, chromium, and molybdenum, but with no vanadium, and Herbrand has accordingly omitted the Van-Chrome trademark. The markings are difficult to read due to the extensive pitting. The overall length is 7. The original finish was probably nickel plating, but all traces have been lost due to extensive rust and pitting.

The inset shows the marking "" forged into the reverse side, indicating the use of AISI steel. This steel is a triple alloy of nickel, chromium, and molybdenum, but with no vanadium in use, Herbrand has omitted the Van-Chrome trademark. The Herbrand catalog lists this tool for starter and manifold service on "late-model Chrysler" automobiles. It remained in production for a number of years, at least through The shank also has a forged-in code "DZ.

The catalog description explains the work performed by this tool, then concludes with the statement "Ordinary wrenches are useless. The forged-in code "DZ. The "Z" year code in the Bonney date code system indicates production in The overall length is The finish is nickel plating with polished ends, though now worn and darkened by rust.

The side view of the wrench in the top inset shows the angled socket ends, providing clearance for its intended application. The sockets have point broachings. A review of the Herbrand catalogs shows that this wrench was first introduced in the fall of to service through model year Chevrolet main bearings.

Then with a further change by Chevrolet, this tool ended up only applying to early model year vehicles, and another specialty wrench was needed for the remainder of the model year! Previously we saw a specialty socket wrench for Chevrolet main bearing service, and this next figure illustrates the equivalent tool for Ford service. Similar tools made by other manufacturers include the Duro-Chrome Brake Wrench.

The next two figures show examples of the Herbrand V specialty box-end wrench, designed for V-8 Ford brake applications. The top inset shows the stepped offsets in the shank, designed for better obstacle clearance in the V-8 Ford models.

The wrench has a dull plated finish, which according to the catalog is a satin nickel finish. Herbrand continued to use nickel plated finishes after most other tool companies had switched to chrome over nickel.

The shank is marked "Van-Chrome" and "Fremont, O. Stud extractors are specialty tools for removing broken studs, or for installing a new stud. There are several different designs for stud pullers in common use, of which the eccentric cam is probably the most common. The diameter of the body is 2. To use the extractor, the stud to be removed or installed is inserted in the appropriate hole, with the cam moved to one side.

The cam is then driven with a ratchet or breaker bar, and the eccentric pivot means that the cam will grip tighter as more force is applied. Herbrand produced a variety of gear pullers and related specialty tools, including bar pullers, two- and three-jaw models, hub pullers, and presses. The overall length exclusive of the pressure screw is 4. The design of this puller is based on the classic patent 1,, , issued to R. Kaplan of OTC, and acknowledged in the Herbrand catalog. The inset shows the reverse side of the connecting bar, with the rotating notched steel plate used to secure the pins.

Typically this style of puller uses nuts and bolts to secure the jaws, but the notched plate provides a quick and convenient mechanism. The puller is marked with the Herbrand script logo and "U. As with the previous figure, this puller is based on the classic patent 1,, , issued to R. Kaplan of OTC and noted in the Herbrand catalog. The reversible jaws provide a choice of a wide or narrow gripping surface, with the puller configured for the narrow end in the photograph.

The jaws can also be turned over to grip on the inside edge if needed. The Herbrand catalogs lists this tool for Buick head-bolt applications, along with the corresponding S wide-sweep model. See next figure. Other models were listed for Chevrolet service applications. This tool and the similar S model see figure above were listed in the Herbrand catalog for Buick head-bolt applications. The design of this tool is described by patent 2,, , filed by I. Clark in and issued in The design of this tool is described by patent 2,, , issued to I.

Clark in These pliers were listed in the and later catalogs, but not in the catalog. A careful look at the center panel shows a slightly raised ridge of material on the base, and it's also visible in the left panel as a small ridge on the shoulder.

A comparable ridge is present on the other side of the base, in a diametrically opposite position. The marks are subtle, so you'll need to enlarge the photograph with your browser. This ridge is a remnant of the forging operation, showing that the hot socket blank was clamped between two dies while the broaching mandrel was forced in.

This is the method described in the Heschel patent 2,, Later sockets typically show tooling marks where the base was turned in a lathe after forging, but the earlier sockets were apparently left with the base in its rough forged finish. The other panels show additional finishing operations done to the socket. The left panel shows that the drive end has been given a chamfer, for easy insertion of the drive tool, and the right panel shows a comparable chamfer for the point broached end.

The bottom of the interior shows the mass of displaced steel, pushed ahead until it piled up against the square shaft of the broaching mandrel. The center panel shows the finely polished upper walls and the knurled band around the center. Note that the knurling here has simple parallel lines; this style was apparently used from the earliest sockets until some time in the s. The finish is nickel plating with polished upper walls. The base of the socket is smoothly finished, with no trace of the forging marks noted in the previous example.

The finish is nickel plating for the left and middle sockets, and cadmium plating for the righthand socket. Nickel plating was the standard finish during the s and early s, and the cadmium plating on the righthand socket likely indicates production during The sockets are equipped with cross-bar holes, a standard feature for deep sockets at the time, as this allowed spark-plug service with just a socket and bar.

The Herbrand name is marked in block letters on the lefthand socket, but with the script logo on the other two. Herbrand appears to have used the script and block markings interchangeably over a period of many years, without any known meaning associated with one use over the other.

Sometime in the mid s Herbrand changed their socket design slightly, introducing a cross-hatched knurled band to replace the earlier parallel knurling.

The change probably occurred during the latter part of the war years, as examples of both knurling styles are available with cadmium finishes. Although the change in knurling style is not indicated by the regular catalog illustrations, the Supplement No. This Supplement is included at the back of the catalog MS, and pages of the Supplement show examples of sockets with cross-hatched knurling.

By Herbrand's socket design had been updated again, this time to a simple style with no knurling or other ornamentation. Thus the approximate time range for the cross-hatched style can be estimated as Our first example is shown in Fig. The finish is plain steel with polished upper walls.

The plain steel finish and lack of a Van-Chrome marking strongly suggest that this socket was made during the wartime years, when material shortages sometimes forced changes not only in the finish, but in the steel composition as well.

The knurled band just above the base shows the cross-hatched pattern that replaced the simple knurling seen on earlier sockets. Herbrand appears to have switched to the cross-hatch knurling during the mid s, and this socket is probably one of the earlier examples of the new pattern. The socket has been drilled with a cross-bar hole, a common feature for deep sockets at the time. In Fig. The finish is cadmium plating. As with the previous example, the finish and markings suggest manufacture during The socket is equipped with a cross-bar hole, as was standard for deep sockets at the time.

The socket is equipped with a cross-bar hole. As with the previous examples, the finish and markings suggest manufacture during The finish of the sockets is chrome plating over nickel, except for the middle S socket, which has a cadmium plated finish.

The middle socket was likely made in , and the others probably date from As with the previous figure, all are marked "Van-Chrome" and "Fremont, O. The finish of the sockets is chrome plating over nickel, but the chrome has worn down to the nickel layer in some areas. The upper inset shows the broached openings, and for these larger sockets the material displaced by the broach has merged smoothly with the bottom, leaving no separate layer or shelf of material.

The overall length is The ratchet mechanism uses a tooth main gear with dual pawls, and a lobed cam alternately deactivates one pawl to select the direction. Note the use of an external detent ball to secure the shift lever position; this idea was later used by Armstrong for its ratchets.

See the Armstrong SA Ratchet for an example. The forged handle includes deeply recessed panels, serving to provide a firm grip and reducing the weight as well.
