Braces: Part II

By Donald Albury.
This week I continue describing braces that are in the Tison Tool Barn.
In the second half of the 19th century chucks using jaws tightened and loosened by rotating a shell came into use on braces. William Henry Barber was issued a patent in 1864 for what became known as the Barber chuck. The Barber chuck has a pair of spring-loaded jaws inside a rotating shell. The jaws are arranged so that they make contact along their full length with a square tapered bit tang. The rotating shell tightens or loosens the jaws depending on which way it is rotated. The Barber chuck, with various improvements introduced over the years, became a popular style of chuck for braces.

The Tison Tool Barn holds several braces with jawed chucks. First is this brace with a Barber chuck and a wooden head and sweep grip. There are stamped markings in four different places: "F. BUNNY", "F. DUCK" (twice), and "G. ROCK". I have no idea what those markings mean. This brace is 14.5 inches long and has an 11 inch sweep.

While a brace was an efficient tool when the crank could be swept in a full circle, it became much less useful if something obstructed a full sweep. The invention of a ratcheting mechanism solved the problem. William P. Dolan was issued a patent in 1871 that became the basis for most ratcheting braces, in which the sweep could be swung back and forth, turning the bit in only one direction. Ratcheting braces normally have three settings, turning the bit clockwise only, counter-clockwise only, or locked, so that the bit always turns with the sweep.
This ratcheting brace, which has a Barber chuck, is marked "NO. 33" and "PAT PDGY.18 1880". "PAT PDG" is short for "patent pending", but the rest of the marking is confusing. The PDG may have been stamped over JUL in what was originally JULY 18 1880, or the date was added in an attempt to overstamp PDG. A (rather cursory) search has not found a patent with that date for either a brace or a chuck. "NO. 33" is probably a model number, but I have no clue as the manufacturer of this brace. The brace is 13 inches long with an 8 inch sweep.

Here is another ratcheting brace with a Barber chuck. It is marked "STANLEY" and "NO. 945-10 IN." I have seen comments on the Internet that the model 945 was offered in the 1920s and in the 1950s, so this brace is likely between 60 and 100 years old. It is 13 inches long, and has a 10 inch sweep.

The next brace, shown below, is marked "P. S. & W. Co." and "59 1/2". The Peck, Stow & Wilcox Co. was formed in 1870 by the merger of three companies, and continued in business until 1950. This brace appears to have a Barber chuck, which indicates that it was probably produced in the 20th century (braces with Barber chucks are shown in a 1911 caralog from P., S. & W). The "59 1/2" appears to be a model number, but the few model numbers I have seen for P. S. & W. braces have been four digits long with no fractions. This brace is 11 inches long and has an 8 inch sweep.

Below is another ratcheting brace from the Peck, Stow & Wilcox Co. with a Barber chuck. The Brace is marked "P, S. & W. CO. 2010". Again, the Barber chuck indicates that this brace was probably manufactured in the 20th century. The brace is 13.5 inches long, with a 10 inch sweep.

The next brace is also from Peck, Stow & Wilcox Co. It has a Peck and Powers-style interlocking jaws chuck. (The Peck of Peck and Powers apparently had no relation to the Peck of Peck, Stow & Wilcox.) The Peck and Powers chuck was patented in 1879.

The brace is marked "P., S. & W. CO." and "1003". The lack of a patent number for the chuck on the brace indicates this is a later model. The brace is 13.5 inches long with an 8 inch sweep.

The brace below is a corner brace. The rotary motion of the crank is transmitted through gears to the chuck. The brace is not marked, but appears to be a Fray model 100, but with a Barber-style chuck rather than the interlocking jaws chuck pictured in the 1911 Fray catalog. This model was also made by Stanley after it acquired Fray, and it may have been produced for sale by other companies. The brace is 17.5 inches long and 9 inches wide. It has an 8 inch sweep.

The last brace in this post is more of a toy than a working tool. It probably came from a child's tool kit. The handle on the crank is short, and not really big enough for a grown man's hand. The sweep is narrow, producing a low torque suitable only for drilling very small holes. The chuck is simple. There is a ratchet, similar to ones on mechanical screwdrivers,  just below the head. The brace is 12.5 inches long, with a sweep of 2 inches.

Braces: Part I

I was pleased to learn this week that the Tools and Hardware section of the Collectors Weekly web site has linked to this blog as a Great Reference Site.
A Brief Note on Augers
I could say that the search for truth is unending, but that seems a bit pretentious when talking about old tools. I have found, less than a week after my last post, more information about the history of augers. D.B. Laney posted a few days ago about the book Country Furniture by Aldren Watson. I've had a copy of the book for 40 years, but hadn't looked at it in a long time. I agree with Laney, this book is a real pleasure to browse through. Watson does mention (page 97) that a single cutter spiral auger with a gimlet point was invented about 1770, but the gimlet point was narrow and frequently broke. The 1809 patent that I referred to last week was apparently for the double cutting edge on a spiral auger, rather than for the gimlet point. Another source I just found on Wikisource is the article on "Boring" in the 1879 issue of The American Cyclopedia. Figures 7 through 16 illustrate the various forms of augers and auger bits in use up to that year.
Braces: Origins, Sheffield and Spofford
This issue of my blog begins a description of the braces held in the Tison Tool Barn. I will finish this topic next week.
A brace or bitstock is a woodworking tool used to bore holes in wood. It has a U-shaped section offset from the shaft of the handle that forms a crank. One end holds a bit, which will bore into wood when it is turned. The crank allows the woodworker to rotate the handle with one hand while pushing down on a knob or pad (the head) at the end of the brace with the other hand, imparting a continuous rotary motion to the cutting end of the bit. The sweep is the diameter of the circle swept out by the crank handle as it is turned. The wider the sweep, the greater the torque that can be generated with the brace.

A brace and set of bits were essential to woodworkers well into the 20th century, but have been largely replaced by power drills. I bought a brace and set of auger bits some 50 years ago, but have not used the auger bits for 35 years. I have used the brace with a screwdriver bit on occasion. 
The brace is a relatively recent addition to the woodworker's tool chest. The oldest known surviving brace was found on the Mary Rose, an English warship that sank in 1545. The first known depiction of a brace is in a painting by Robert Campin completed sometime between 1425 and 1428. In the detail below, St. Joseph is holding the brace in an awkward manner that makes me suspect that neither Campin nor his model had ever seen a brace in use.

The earliest braces had a bit permanently mounted to the brace. A woodworker would need a different brace for every size hole he wanted to bore. Eventually a socket was introduced into the end of a brace, in which a wooden pad mounted to a bit was held by friction, or by a thumbscrew. The sockets and pads had a square cross-section. Some early sockets and pads had the same width for their full length, but the development of tapered pads and sockets allowed for easier insertion and removal of bits while still achieving a tight fit. Wooden pads for bits were eliminated by the development of tangs, in which bits were given a tapered end with a square cross-section.

A mechanical device to secure the tang of a bit to a brace is called a chuck. There have been many types of chucks and many styles of braces in the past two centuries. I will only cover ones for which examples are found in the Tison Tool Barn.
One early method of securing bits to a brace was the cut-tang chuck, in which the tang has a slot which is engaged by a spring-loaded hook.

The brace shown below is a Sheffield-type brace with a push-button chuck. A push-button chuck is a type of cut-tang chuck. The button pushes the hook clear, releasing the bit. There are no markings on this brace. A book on 18th century tools published in 1816 has an illustration showing a brace with a push-button chuck. Similar braces were made through most of the 19th century. The brace is 13.5 inches long, and the crank has a 7 inch sweep.

The next brace is another Sheffield style brace with a push-button chuck. This brace has brass (or brass-plated) reinforcing plates attached to the curved sections of the brace. The only markings on the brace are the name "JOHN GREEN" with unevenly spaced and aligned letters, and "1816" in another location. "John Green" is probably an owner's name. The number is a problem. I doubt an owner would bother to stamp a date on his tool. A manufacturer might stamp a part number on a tool, but that is seen primarily on metal tools. A year may appear on a tool as either the date the manufacturer was founded, or the date a patent was issued, but neither is the case here. I suspect the "1816" was added at some point to make the tool seem older, and therefore more valuable. The brace is 11 inches long and has an 8 inch sweep.

The brace below is a Sheffield style brace with a lever release chuck. This is another type of cut-tang chuck, in which pressing the lever lifts the hook out of the slot on the tang. It has brass reinforcing plates on the curved parts of the brace. It is stamped "Made for T. TILLOTSON SHEFFIELD". Thomas Tillotson was a merchant and dealer in New York. The business, an old family firm, became "T. Tillotson" after 1843, when Thomas's brother John left the firm, and appears to have closed by the beginning of the Civil War. This leaves a well defined time period in which the brace was probably produced. The brace is 14 inches long, and the crank has a sweep of 7 inches.

This next brace is a steel brace (even the head is metal). It has a Taylors Patent chuck, which is another type of cut-tang chuck. Jeremy Taylor of Connecticut patented this chuck in 1836. The brace is also marked "I. WILSON". Increase Wilson manufactured tools starting in 1818. His business became a public company under the name "Wilson Manufacturing Co." in 1855. This brace is 12 inches long, and the crank has a 9 inch sweep.

In 1859 Nelson Spofford received a patent for a "clamshell" type of chuck. This chuck was formed by a fork or split at the end of the brace, with a channel for a bit tang. The chuck was closed on the tang like a vise by turning a thumbscrew. The Spofford chuck was used starting in 1859 on braces produced initially by Fray & Pigg Manufacturers, and from sometime before 1866 by John S. Fray and Co. Stanley Works acquired John S. Fray & Co. shortly after 1900 and continued to manufacture Spofford chuck braces until 1942.

The brace below has a Spofford chuck. It is marked "JOHN S. FRAY" and "BRIDGEPORT, CT." The wood head and rotating wood grip on the crank indicates that this is a later model from Fray. The wood crank grip is two parts held together on the crank by pewter rings. The brace is 11.75 inches long, and has a sweep of 13 inches.

This next brace is not marked, but is very similar to the one above, and likely also from John S. Fray & Co. It also has a wood head and crank grip, and is therefore from sometime in the later part of the 19th century or the 20th century. The brace is 11.5 inches long and has a 17 inch sweep.

I will cover more braces from the Tison Tool Barn next week.

    I have been a volunteer at the Matheson History Museum. Feeling an affinity with old hand tools (some of which I remember from my youth), I have tried to learn more about the history of the tools in the Tison Tool Barn, and how they were used.

    I am not an expert on tools. I have used some of the tools represented in the Tison Tool Barn, though perhaps not very well. I do enjoy digging around to find out more about the tools, and hope that some of you share my interest in the old tools collected in the Tison Tool Barn.

    This is my personal blog. Any claims, suppositions or opinions offered here are mine, and do not necessarily represent those of the Matheson History Museum, its staff or its Board of Directors.
