TUNING HAMMERS

This page is devoted to Hale hammers; other various Hale piano tools are shown throughout this ‘site. The Hale tuning hammer was one of the best on the market, from its invention in 1885, but there was competition from Erlandsen, whose tool production had already been established since 1863, and from Hammacher Schlemmer, whose hammers were mostly made by Erlandsen. After WWI, Hale hammers became more of the leading choice for piano technicians and tuners. Market share increased after 1929, as the industry shrunk, Julius Erlandsen downsized his business during the 1930s, and Hammacher Schlemmer moved to midtown Manhattan in the 1920s, and became more interested in marketing the high-end novelty items that they are known for today. Hale hammers went through a number of permutations during their production, which lasted well over a century. This review of the Hale hammers does not purport to be a type study along the lines of the many Stanley tool studies (where there are all too often many examples of exceptions to the various categories), but more of a general review of the the history and development of the Hale tuning hammer. In compiling information for this, I have used U.S. patents, advertisements, technical circulars, catalogue excerpts, and the actual tools. As far as I know, there has not been any previous outline or retrospective done on this very specialized subject, so I’ve put it together from scratch, relying on what information that I have been able to cull. This also applies to my page on the history and development of the Erlandsen tuning hammer.

USING HALE HAMMERS

Earlier Hale hammers (1885-1913) with German silver hardware–while some of the most beautiful tools ever made–had an extension feature that was not as robust as the later hammers. Hale hammers with the pre-1908 tuning tips were more suited for tuning older American pianos in original condition up to the early 1960s, and for many European pianos.

Good used Hale hammers made after 1914, however, are still in demand from some tuner technicians who appreciate traditional methods and vintage tools that are still usable in a practical sense. Post-1908 tuning tips are interchangeable with more current APSCO, Schaff, and Watanabe tips, and the 1/8″ tapered pipe thread (introduced c. 1925) for the head and shaft is still used on Schaff and other modern hammers. A full range of hammer head lengths and shaft boring angles (from 5 to 25 degrees) were available, making the Hale hammer quite versatile for a wide range of tuner preferences, including an extra long head and tip for stringing, which allowed for extra clearance over the cabinet while pulling up the string tension. The steel compression nut (introduced c. 1916) locked down the round shaft (c. 1942–1990s) securely, but the octagonal shaft (c. 1909-1942) was even more solid with no rotational movement under stress. Later Hale hammers with grey Polypenco nylon handles (c. 1955 to the 1990s) were practically indestructible but rather ugly. A major advantage of Hale hammers was the ability to fit various tuning tips with larger sizes for tuning pin sizes 3.0 to 6.0 used for restringing, and a smaller size for European and late 19th century pianos. Changing the tuning pin tip had to be done in the shop, though, because removing the tip from the head required a tip wrench clamped in a bench vise, and some force applied. For practical purposes in the field, separate heads would be carried, or even a second hammer with the alternative size tip socket. Post-WWI Hale hammers were different from all of the other types of antique hammers because they could be used to tackle just about any tuning or stringing scenario, while most other antique tuning hammers were good for performing a more specialized range of tasks. The structural integrity of the adjustable extension handle combined with the almost unlimited choices of heads and tips enabled the tuner to use it in almost any situation, from serious concert tuning and factory stringing, to quick and dirty remedial tuning on a spinet gone unserviced for 40 years.

SOME HALE HISTORY

Francis Hale (1853–1933) was a music student at Boston University when he submitted his patent application on February 26, 1884, for this tuning hammer.

His tuning hammer invention featured a collet tightened by an adjustable nut, which secured the variable extension lengths of the shaft. I believe that he was influenced/inspired by the adjustable tool handles which had become commonplace by the 1870s (see “Combination Handles” page). In the example shown below, there are several shallow holes drilled along the shaft to provide places for an auxiliary set screw which is located toward the back of the ferrule. This set screw is seen in the left hand side of figure 1, item “a”, of the patent illustration above. On the opposite end of the shaft is a fork-shaped clutch which, when the extension is fully retracted, provides a very secure means of unscrewing/removing tuning heads that can be very tight. This is shown as “D.” in the patent illustration. Item “e” is a brass pin drilled through the back part of the handle and through the internal hardware, to insure that it remains secure in the handle and will not work loose or rotate. The head, “A,” is made of regular steel near the shaft,, and hardened steel near the socket for the separate tip, appropriate for securely screwing the tip into the hammer head socket. This separate tip, “f,” with male threads, is made of soft steel, and then hardened steel at the tuning pin socket, to withstand the hard usage and wear of turning tuning pins. The principal benefit of this arrangement is that the tuner had available a choice of socket sizes for the variety of pin sizes and shapes found in pianos in the late 19th century. This tuning hammer model essentially marked the start of the (Hale) Tuners Supply Company.

Early Hale hammer, c. 1890s, with head very close in appearance to that shown in the 1885 patent, the date of which is inscribed on the matching original double oblong head for it. This hammer has a ferrule, collet, and adjustment nut, all made from German silver, and Hale used German silver for this hardware until early in the production run of the “Cup-Joint” model, c. 1916 or so. German silver was used in many higher end tools in the second half of the 19th century, as it was showy, relatively easy to work, resisted corrosion, had low friction, and was somewhat more durable than brass. It had many uses, such as for piano center pins, keys for woodwind instruments, flatware, and jewelry that Indians made on the Great Plains. Manufacturers of this alloy, 60% copper, 20% nickel, and 20% zinc (with varying combinations), would compete to achieve the most silver-like appearance.

The set/guide screw, was moved to the front of the ferrule, near the adjustment nut, and the shaft had a channel along its length, rather than divots for the set screw, allowing an unlimited number of length settings. And the shaft extension now had a flare, which provided a friction locking/mating surface for the head. In other respects, the 1885 Hale tuning hammer remained pretty much the same as before.

Oliver Cromwell Faust (1859–1947), witness to Hale’s 1885 patent, and author of Piano Tuner’s Pocket Companion and The Pipe Organ and Player Piano–Construction, Repair, and Tuning, was also a student at Boston University at the same time as Francis. Francis Hale and Oliver Faust went on to work as colleagues at the New England Conservatory, with Faust as an instructor and teacher of a piano tuning program, and Hale as the business director and an instructor. Faust’s “Tuner’s Pocket Companion” remained in print for the entire duration of Hale, Tuners Supply’s tenure in business, and is still available today from Schaff Piano supply, who bought out the Hale name.

A piece of history included in the 1935 Hale catalog:

The 1930 catalog mentioned the introduction of the detachable tips. The illustrations of the horse and carriage and the airplane underscore the dramatic changes that occurred in technology during the span of those years.

Tuners Supply, or Hale’s mailing address, was Winter Hill, Boston 45, Mass. Their actual address was on Wheatland St., in Somerville, MA. Various street numbers found–for the same location–are nos. 88, 89, and 94. I remember going there in person, on numerous occasions, during my student years in the late 1970s, early 1980s.

Boston University Yearbook for 1884. This was the entire third year class in the College of Music, which was established in 1872. The B. M. was a three year program at the time; the B. A. required the traditional four years.

From the 1938 Hale catalog. The connection between Hale and Faust was lifelong.

A drawing of the $50 tuner’s kit is shown on the intro page.

In Albert Hale’s well-known 1906 patent, there are two changes: a single head with multiple sockets, to allow for the extra clearance needed for plate struts on grands, and the case in the treble area for uprights. A version of this was realized in production with the added socket on the stringing “T” hammer shown on the second photo below. The tip was now equipped with a female screw socket and the head contained the male screw threads. Tips were made hollow all the way through, with the tapered-flute, star socket ending where the machine threads started for screwing the tip into the head. At the socket, the tip was hardened for the tuning pins, but left softer at the threaded part, for a more secure fit into the hardened steel of the male threads on the head. A primary purpose of this change was to eliminate problems detaching the tip when the tip would break, leaving the internal male threaded section inside the head. Albert Hale:

“In the style now in common use the breaking of this detachable portion is frequently the source of much trouble and expense, as the intersecting section must be milled or chipped out. This often results in ruining the threads of the head, causing the loss of the entire tool. In my invention, this is impossible.”

This is the familiar patent that is marked on the tuning pin tips from the mid teens to the early 1950s. From 1906 to to the mid teens, the tips were marked in various other ways, some with the month and year, and some of the others with (Hale) Tuners Supply, Boston.

Albert L. Hale (b. 1884) was a son of Frank W. Hale. He left the family business sometime before 1920 and moved to Tacoma, Washington where he raised a family.

Engraved on this ferrule is “Hale Imp. Pat.,” which dates it to 1905 or 1906.

Hale’s “T”, or stringing, hammer also featured a socket for the lever, which provided another lever head which was much taller and permitted more clearance over obstructions, such as plate struts and protruding screws, found on many pianos. This was a variation on the patented idea of a single head with multiple sockets.

A selection of Hale tips. The screw socket in the center, below, is a larger diameter, and was probably produced for a couple of years preceding the 1906 patent until 1908, and the one second from the left, with a smaller diameter screw threaded socket, was made after 1908 right up to the 1990s. The tip in the center reveals a hollow cylinder, which , in addition to being more easily removed if broken, made it easier to temper the tip, permitting water to be forced up the desired fluted portion. Early tips, from the inception of the Hale hammer in 1885, had a male screw with the socket in the head, shown second to right. Two tips on the far left and right, are examples of the varying tuning pin socket sizes available:

Same version; ornate double oblong head and narrower handle.

This model has a larger adjustment nut, a differently shaped handle, and most significantly, an octagonal shaft, which was a new way (for Hale) to prevent rotational slipping. Hale continued to use the octagonal shaft in their hammers until the early 1940s.

DSC01569

This version has a tapered shaft and a more angular adjustment nut. The head accepts the post-1908 tuning tips.

Looking similar to the drawing in Julius Erlandsen’s 1904 patent, is Hale’s tapered shaft, which was produced approximately eight years after Erlandsen’s. Hale placed the threads towards the back of the tapered section instead of at the front, as in Erlandsen’s.

Three “Cup-Joint” tuning hammers. This concept was put into production without the slot on the back of the head, shown in the patent illustration below, which would produce a pinching effect on the threaded part of the shaft.

The hammer at the top of this photo is engraved with “patent pending,” which dates it to 1914–1915. Relatively early in the production run of the entire series of the Cup Joint model, c. 1914–1925, German silver was discontinued. The adjustment nut was changed to steel and the ferrule was made of nickel-plated brass, as shown on the hammer in the middle of the photo. The plating invariably wore through rather quickly on these hammers, but the steel adjustment nuts held up better than German silver under heavy prolonged use. This model still had the straight, not tapered, thread, which Hale phased out c.1925–1928. A cup on the shaft was eliminated in the version shown at the bottom of this photo, and a locking nut was used to secure the patented head instead. This tool belonged to the grandfather of my late business partner; he was a blind tuner.

1914–1915 version.  Here is the patent for this design.

Harold E. Hale (1889–1972) was another son of Francis Hale. In the 1930 census, Harold and brother Otis C. declared that they were managing a piano supply company (Tuners Supply). In 1930, Frank W. stated his vocation as a piano tuner. All three men owned their houses, as shown in the 1930 and 1940 census records, which is one indicator that the Tuners Supply business was profitable.

A “Heavy Duty” model was introduced sometime before 1920, during the production of the “Cup-Joint” model. It is one of the few Hale tools that catered directly to the needs of the piano factory tuners, instead of the outside, or finish tuners. Thanks to Larry Lobel for this circular.

Cup joint model–version most produced.

“Cup-Joint” model was replaced with a 1/8″ tapered pipe thread on the shaft, introduced c. 1925. This particular threaded model with octagonal shaft was offered until at least 1940.

Unthreaded, friction-fit model, intended for stringing, chipping, and rough tuning in factories.

Here is the 1935 catalog description of the threaded and unthreaded shaft. Incidentally, this is the last offering of a double oblong head that I’ve seen.

An example shown at the bottom of this photo, made c. 1940–1945, was the last version to feature a rosewood handle, until Tuners Supply reintroduced rosewood as an option in 1985. This example has been shortened by a previous owner. Hale returned to a round shaft, as used in their original version, and the shaft thread retained the 1/8″ tapered pipe thread (1/8″ = inside diameter of pipe), which allowed for limited exchangeability between heads of different manufacturers. Early postwar models were made with laminated exotic hardwood veneers, impregnated in Bakelite resins—this was called “Artwood,” as shown by the two examples at the top of this photo. These handles are distinctive looking and are still in demand by tuners. Later models were made with grey Polypenco nylon and a nickeled brass ferrule. Otherwise, this model remained essentially unchanged until the sale of Tuners Supply to American Piano Supply Co. in the 1990s.
