The lever 23 when thus actuated will in turn actuate a lever 3| carrying a pin 32 against a spring 33 to remove said pin from a recess in a notched hollow disc 34 driven by a spring motor 34a therein connected to shaft 32 to thereby release said motor. In other words disc 34 and one end of spring 34a are fixed to shaft 32. This motor34a is provided with cams 35 and 33 respectively, as shown in Fig. 6, which are driven in unison. Cam 35 is cut to provide the registration and-recording of the watchmans box number, as will be hereinafter described in connection with Fig. 6. The member I! and lever |3 are returned to the position shown about fifteen minutes before the point 21 on the cam reaches the free end of the lever 23, a pin- In on said cam engaging. a pin23 on said member.

If the watchman desires to transmits firealarm he-manually operates a handle 31 to rotate a shaft 33 provided with a small cam 33 which operates a bell crank lever 4| on the plate 3 to likewise actuate the lever 3| to. release the motor 34a. The cam 35 is cut to provide 1 the fire signal and the shaft 33 is provided with an additional cam 40. This cam 43 normally renders a lever 42 pivotally mounted on plate |3a inoperla tive to respond to the configurations of the cam 33 but when actuated by the fire handle 3l it permits the separation of contacts 43 associated with said lever in accordance with said configurations to correspondingly control a switch by means.

The mechanisms in the watchmens boxes are time-controlled from the subscribers oflice, a

master clock therein being provided with cams 5| and 52 (Fig/8) in juxtaposition on a shaft 53 of the master clock which makes one revolution per minute.- These cams are provided with drop positions 54 and 55, respectively, the latter occurring at a slight time interval behind the former. so that 'apgoted lever 56 having an elec-' t'ricalcontact 51 t e gagement with a contact 53 on a second lever 53 will be separated." These contacts-51 and 53 are as shown in Fig. 5 in circuit with a magnet 3| at each watchmans box whereby animpulse reon and riding on the camp 54 may be actuated to bring said' contact inen-r is delivered each minute to actuate an armature 32 on a bell crank lever provided also with a hook- 1 shaped member 33 for advancing the gear 3 one tooth per minute. The lever carrying the armsture 32 and member 53 is provided with a yieldable pivot, it being pivoted on the free end of a lever 64 and provided with a spring 35 yieldably drawing it toward the center oi' .the gear 3.' A spring pressed pawl 33 is provided to prevent back-lash.

Since the master clock at the subscribers ofllce controls the entire system, means. are-provided to indicate failure of the master clock. This means is illustrated in Figs. 7 and 11'.v The pendulum 31 of the master clock (not shown) is'prol5 vided with a trough-like proiection' 33. A small pendulum 63 skips over-the. projection 33 with each swingbut should 'the'pendulum 31 stop the pendulum 33 will engage in the trough just prior to stoppage of thela'rg'e pendulum and be actuated, causing a pivoted lever II to rise'andallow is pivoted weight 12 to drop andv keep said lever in the-up position. The lever 1| carries an insulated contact 13 which when said. lever is in up position engages a similar contact I4. These a source of current 15 and a magnet 13 whereby when the latter is energized itwill actuate an armature 11 provided with a pin". The pin 13' normallylocks a spring motor 13 and when the armature 1! is actuated said motor is released."

The motor 13 is connected with suitable alarm 2 devices.

Means are provided to prevent over-windingoi the spring motor 34a by the watchmanas' he auto,-
