Counter-irritation device, patent model, 1860. Improved version of Baunscheidt's _Lebenswecker_ patented by Alfred Stauch of Philadelphia (U.S. patent no. 28697). Stauch added a brush around the needles 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.) Barber-surgeon's kit, late 18th-early 19th century.
