拍品描述
U.S. Patent Model, Salesman's Sample or Exhibition
Model for Electric Safety-Grating, c. 1905
Patent No. 763890 by Gustav T.E. Henriksen, Milwau-
kee, 28 June 1904, painted metal case with 2 horizontal
crossbars and 21 vertical tubes with sliding inner rods
with electric terminals connected to alarm bell system
mounted on the top, with door, lock and brass plaque
engraved: "Henriksen Electric Safety Grating System,
Pat. Jun. 28 1904, Chicago, USA", height 16 in. (41
cm) x width and depth 16 ¼ in. (41,5 cm). In original
metal transport case. Henriksen filed his patent applica-
tion for "improvements in safety-gratings" on 2 Decem-
ber 1903. The object of his invention was to "prevent the
severing of grating-bars and to give an alarm in case of
an attempt to do so". It features an arrangement of
vertical tubes encasing revolvable rods suspended from
notched collars at the upper ends and connected to
electrical terminal at the lower ends. The rods are held
loosely in their collars by cross-pins. Attempting to cut
through the outer tube rotates the inner rod, the pin
drops into the notch in the collar and the lower end of
the rod engages with the electrical terminal, which
closes the circuit and activates the alarm. Included with
the model are copies of the original patent application,
patent, a 1910 patent by Henriksen for "Oiling Devices"
and related papers. A fascinating exhibition piece!
