Peter Stubs was an important Lancashire, England, toolmaker who began manufacturing tools in the mid eighteenth century. The tools made by Peter S. Stubs in the Museum collection are typical of those which the Stubs Co. imported to the USA in the 19th century. A detailed description of Stubs role in the Industrial Revolution is contained in E. Surry Dane's Peter Stubs and the Lancashire Hand Tool Industry located in the reference section of the visitor's tool examination area.
The following clock and watchmaker tool illustrations and descriptions are from John Wyke's 1978, A catalogue of tools for watch and clock makers.
Plate 10: Slideing Tongs [and] Spring Dividers
Tools 230 to 237
Sliding tongs were used to hold small parts in such a way that they
could be handled in different positions for filing, etc., but unlike pliers
in that the work was clamped in the jaws. Clamping was done by sliding
the collar or "thimble" down the arms with the work in place; the small
dovetail slot which appears in the lower arm, near the thimble in each
tool, was for securing the spring between the arms to open them. The arms
of sliding tongs are flat, and the whole tool could be held in a bench
vise if necessary.
230. round Noses: With jaws cut away on both faces and a slot
to hold wheel arbors.
231. Balance wheel: Jaws with one face cut away to accommodate
the pallets of a balance verge.
232. Flat Noses: With flat jaws to hold flat items.
233. broad Chops: See no. 232.
234. Slant Chops: See no. 232.
235A-E. Spring Dividers: Multipurpose tools for marking out.
Made of steel with a steel hinge spring. All adjusted by means of
a wing nut, and no. 235A has a small locking nut inside the left arm for
making sure that the measurement is not disturbed.
236. Kerb Dividers: With one point adjustable, used for marking
out a watch slide, or curb, and general fine work.
237. Spring Caliper: Like no. 235, with a spring hinge used
to take outside measurements. Properly belongs to the group of calipers
on plate 13. (pg. 48).
Plate 31: Wire drawing Plates
Tools 331 to 337
Drawing plates were of hardened steel, pierced with tapered holes decreasing
in size, through which wire of a desired section could be drawn to the
required diameter. The plates shown here were more applicable to casemakers'
use rather than watchmakers', as gold and silver wires of different sections
were drawn on a wire-drawing bench using these plates. Pinion wire, from
which clock and watch pinions were cut, was also drawn using plates of
this kind with holes of pinion section, but no pinion plates are shown
either in this catalogue or those of FWB [Ford, Whitmore and Brunton of
Birmingham] or Stubs, as pinion wire drawing was a specialized trade, not
undertaken by repairers.
The diminishing sizes of holes were used progressively in the plate,
and each hole was of tapering section. On the drawbench the wire to be
drawn was threaded into the largest hole, held firmly between pincers connected
to a strong leather strap, and pulled through the plate by means of a capstan
which wrapped the strap around its arbor. In later drawbenches the wheel
was often geared down to provide greater power. The wire thus drawn was
used for edge moldings on watchcase bands and bezels. To draw wire successfully
it had to be annealed after several drawings to prevent it from becoming
too hard and consequently snapping.

sizes. (pg. 90).
Plate 33: Screw Plates, and Taps
Tools 338 to 345
Screw plates of hardened steel were used to form the threads of screws
for clock and watch work. Each plate had threaded holes, in twos or threes,
of diminishing sizes for different-sized screws. The action in making the
thread was to squeeze the thread on the softer metal of which the screw
was to be made. The tool was used by holding the wire to be screwed in
a vise and turning the tool onto it by hand. Small screws could, however,
be turned into the plate. The handle on each plate provided leverage and
in some had a convenient loop for hanging the plate on a hook when not
in use (for larger sizes, see PI. 34). A lubricant such as lard oil was
essential in screw making. The letters labeling the holes on nos. 338-45
indicate increased hole size as the alphabet progresses.
Taps were for threading holes for screws in brass plates, etc., and
the various sizes shown by letter correspond with the letter sizes on the
screw plates in nos. 338-45. The taps have shanks which could be turned
by pin tongs, or a hand vise for larger ones. Pitches and sizes of screw
threads are now standardized. This was not the case in the eighteenth century,
although Lancashire threads remained the same. Tap sizes A, B, and C are
shown but not labeled on screw plates nos. 338-41. (pg. 94).
