and an
additional spring to force the needles back after they had entered the
skin. The brush could be oiled before the operation, thus saving the need
to oil the wound afterwards. The device is similar to the _Lebenswecker_
in size and construction, except that it was made of a lighter colored
wood and was trimmed in brass. Transferred from the U.S. Patent Office
1926. L 245 mm, D 20 mm. Neg. 72-11290 (BW). NMHT 89797 (M-4299).

Counter-irritation device, patent model, 1866. Patented by Friederich Klee
of Williamsburg, New York (U.S. Patent 55775), this instrument is another
modification of Baunscheidt's _Lebenswecker_. It is made of wood and
brass, and is much shorter than the _Lebenswecker_ but operated in the
same manner. A screw on the handle served to regulate the length of the
needles. A further innovation was the addition of a diaphragm of leather
through which the needles pass. The leather could be saturated with oil
before the operation, thus again saving the need to apply oil afterwards.
Transferred from the U.S. Patent Office 1926. L 92 mm. Neg. 72-11274. NMHT
89797 (M-4305). (Figure 123.)
