What I judge to be the earliest P.S. & W. brace in my collection is this
sleeve (no ratchet) brace with an interlocking jaw chuck. The lower bow on this
brace is marked with the patent date, Feb. 11, 1879 and "No. 92." The patent is
one issued to Obed Peck and D. Powers for a chuck with interlocking jaws that
are grooved on their bases to fit with threads on the inside of the chuck shell
(Obed Peck does not seem to be related to Seth Peck, who is the "Peck" in the
company name). This patent appears on later braces by P.S.&W. and apparently was
their basic chuck. This brace differs from later ones by having a chuck shell
that is not knurled, but has longitudinal grooves on its outer surface. Also the
cup handle is fastened to the underlying fully clad quill by two screws that are
fitted by bolt heads on the top of the decorated cocobolo handle. This feature
disappears in later braces.

The earliest
ratcheting P.S. & W. braces in my collection are those with the same 1879 patent
data stamped on the lower bow, and a December 30, 1884 patent date stamped in
the top of the ratchet housing. There are three brace patents listed on this date
(only two of which are in Pearson), but the most likely is the one issued to
Caspar Reising (No. 309,876) which included pin selectors
to alter the ratchet setting. George Langford was diligent enough to ferret this
patent out, and pass the information along. The braces marked with this patent have two
selector pins protruding from the top of the ratchet housing. Each of these
moves the ratchet dog to engage or disengage the ratchet gear. Braces of this
type have double knurled chuck shells, and the fully clad, decorated cocobolo
handles are fastened with three screws through the quill flange that do not
engage exposed bolt heads on the top. Representative braces include one with 8"
sweep marked "No. 103"; and 10" sweep marked "No. 102."
Chuck Zitur owns a 1911 P.S.&W. catalogue in which the pin ratchet selector
still appears (Per. Comm)..

Slightly
later braces appear in which the 1879 patent date remains on the bow, but the
1884 date is no longer carried.. These braces use a ratchet selector system that requires
manually flipping the ratchet dogs from either side of the exposed ratchet gear. .
Apparently the pin selector system was unwieldy. The new ratchet is quite
similar to that patented on Feb 19, 1884 by R.C. Ellrich (#293957), but is not
marked as such.. Representatives of this type of
selector are found on my braces that include a 12" brace marked, "No 1001" and a
10" brace marked "No 1002," and 14" brace marked, "1200.""The latter
two braces do not carry the 1879 patent date
(which probably expired). They have other features that look later. For example the
wrist handle is positioned by steel retainer rings that are screwed to the frame
(the earlier braces have cast pewter retainer rings) and there is less
decoration on the cocobolo cup handle). The 14" brace is equipped
with a "Samson" chuck having an 1895 patent date.


The brace above
is fitted with an early "Samson" chuck (that has the patent date stamped on it).
Note that this brace, in the uncommon 6" sweep, has the exposed manual ratchet
dogs and screw-fastened wrist handle retainers. Dating to about 1900, this brace
is numbered, 1204. It has two P.S.&W marks—the older "P.S.&W. Co." mark and the
newer one featuring a hand with cold chisel in a circle, with "P.S. & W.,
Guaranteed" around the circle. The latter logo was replaced by 1927 with "Pexto"
in an oval, surrounded by "Southington, Conn. USA". .
