Title: Improvements in Automatic Fire Alarm Systems.
Filed: 1903-10-27
Granted: 1903-12-10
Abstract: 23,302. Bowell, G. B., and Pearson Fire Alarm, Ltd. Oct. 27. Alarms, fire and temperature.-In an automatic fire-alarm system for a fire call, the code message, carried on the wheel b of the transmitter T, is repeated several times, but to indicate a break in the thermostat wires A, B, connected by open circuit thermostats, the code is signalled once only. The relay R is in series with the parts M, a, b, T, E, and in shunt with the relay r. The disc g makes contact with the brush h after one revolution of the wheel b. Normally, the circuit is M a b T x t B r a, but, in case of a fire, the current passes through the magnet E, causing the detent j to release the escapement c, the detent being retained in position by the action of the cam o on the arm p. When either of the wires A, B is broken, the relay R closes the circuit s, and the magnet E releases the escapement. After one revolution of the wheel b the disc g makes contact with the brush h, and the current follows the path M s i h g x E R, thus preventing the wheel b from sending more than one signal. In a modification, the contact of the relay R may be connected to the junction of E, B, instead of to the terminal M as shown, additional gaps being provided in the cam o.

Counting - apparatus.-A pneumatic counting- machine for counting sheets of paper, bank-notes, certificates, transfers, and the like is shown in Fig. 1 and in longitudinal section in Fig. 5. The sheets or notes 1 are clamped to the pivoted and moving table 2 by the spring clamp 3, and are 'lifted up one by one by the suction of the pneumatic lifter 18, which is oscillated by cam action and is connected up to the main cylinder 23. Within the rubber lips 19 of the lifter 18 is a perforated diaphragm 20 to prevent the sheets from being injured. To regulate the suction for sheets differing in thickness &c., the cylinder 23 is fitted with a relief valve 70. The machine is operated by the hand-wheel 28. A rotating device 44, driven from the main shaft 27, carries a sweep 45, which passes beneath the lifted sheet, and a retainer for the sheet. The counter 53, indicating items and totals, is actuated by a piston in the pneumatic cylinder 57, the suction effect of which only takes place when the lifter has been raised sufficiently, and when a sheet is raised. This is effected by the counter cylinder 57 being connected through a port in the hollow trunnion 18<a> of the lifting-device. To prevent registry when the sheets are exhausted, the table 2 is open beneath the lifter 18. The table is moved normally by a spring, so as to bring the sheets into contact with the lifter just after suction has commenced, and is depressed suddenly by means of cam and lever mechanism.
