Patent GB-190306899-A (GB)
Title: Improvements in or in connection with Automatic Fire Alarms and the like.
Inventor: WALKER CHARLES LESLIE
Filed: 1903-03-25
Granted: 1904-06-25
Abstract: 6899. Walker, C. L. March 25. Alarms, fire.-The unequal expansion due to the unequal rises of temperature of two bodies, one of which has a larger surface or is otherwise adapted to take up the temperature of its surroundings more quickly than the other, is utilized to complete or to break an electric circuit. Fig. 1 is a plan, and Fig. 2 an elevation of an apparatus comprising a solid metal spiral b and a metal spiral a made of a section, such as tube, T or U, exposing a large surface. A lever e, with forked end standing above the cups h containing mercury, is pivoted on a frame d, which is supported by the end of the quickly-heating spiral a. A knife-edge f carried by the end of the slowly-heating spiral a normally bears against the lever e and keeps its forked end out of the mercury. When a sudden rise of temperature due to fire occurs, the spiral a expands more than the spiral band lifts the pivot of the lever e sufficiently above the knife-edge to allow the circuit to be completed by the forked end of the lever dipping into the mercury. Another form of apparatus, shown in Fig. 3, consists of two vessels i, j containing mercury leading to vertical tubes h, l. A U-shaped wire n with unequal limbs has the longer limb o in the tube leading to the protected slowly-heating vessel and the shorter limb o' in the tube of the quickly-heating vessel. Normally, the limb o' is not in contact with the mercury, and, if a slow rise of temperature takes place, the mercury in the tube k rises and floats up the wire n thus keeping the limb o<1> out of the mercury. When, however, a sudden rise occurs, the contents of the vessel j expand quickly and the column of mercury in the tube l reaches the limb o<1> and completes the circuit. An arrangement for breaking an electric circuit, when a sudden rise of temperature takes place, is shown in Fig. 4. The vessels i, j are united by a U-tube q containing mercury r, the spaces between the mercury in the vessels i, j, r being filled with an insulating- medium. A sudden rise of temperature causes the mercury in the vessel to expand more quickly than the mercury in the other vessel and the column of mercury in the U-tube q is displaced and the circuit broken. A contact-making apparatus, where a gas is employed as the expanding fluid, is shown in Fig. 5.
