Title: Improvements in control devices particularly for use in the time control of lightinginstallations
IPC: H01J40/00
Filed: 1934-07-12
Abstract: 439,209. Controlling apparatus by light. WESTON ELECTRICAL INSTRUMENT CORPORATION, 614, Frelinghuysen Avenue, Newark, New Jersey, U.S.A. - (Assignees of Lamb, A. H. ; 402, Chilton Street, Elizabeth, New Jersey, U.S.A.) July 12, 1934, No. 20416. Convention date, May 10. [Class 40 (v)] A control device, more particularly for use in the time control of street lighting installations, comprises an electrical relay, a primary instrument for establishing a current flow through the relay which varies in accordance with changes in a factor to which said instrument responds and time-controlled means operating independent of said factor to alter the ratio of the response of the relay to change in the factor affecting the primary instrument. An object of the invention is to enable street lights to be turned off when the morning illumination is substantially less than that at which artificial lighting is necessary at night. Fig. 1 shows an arrangement in which the primary instrument comprises a photoelectric cell C which is connected to the moving coil 5 of a relay, the coil carrying a contact arm 6 movable between relatively fixed contacts 7, 8 in accordance with the magnitude of the current supplied to the relay by the cell C, engagement of the arm 6 with the contacts 7, 8 completing control circuits through a network indicated diagrammatically at 10. According to the invention time-controlled means are provided to vary the sensitivity of the control device at predetermined intervals. Thus the sensitivity of the cell C may be adjusted as shown by means of a clock mechanism 11 which rotates a vane 12 to overlie a portion of the cell at predetermined time intervals or a cam on the shaft of the clock mechanism may periodically operate a switch to close the circuit of an auxiliary lamp illuminating the cell C, Fig. 2 (not shown). Alternatively as shown in Fig. 3, the clock mechanism 11 may periodically shunt a resistance 17 across the relay 5. In an arrangement for automatic street lighting, Fig. 4 (not shown), engagement of the relay contact arm with either of the fixed contacts closes the circuit of a single revolution motor, one revolution of this motor shaft imparting a half revolution to a second shaft, alternate half revolutions of which are adapted to open and close the lighting circuit respectively.

Patent GB-634238-A (GB)
Title: Improvements in thermally operable electric switches or circuit-breakers
IPC: H01H77/04
Filed: 1947-08-05
Abstract: 634,238. Electrically-tripped switches; tumbler switches; thermal switches. METALS & CONTROLS CORPORATION. Aug. 5, 1947, No. 21233. Convention date, Aug. 30, 1941. [Class 38 (v)] A switch, Fig. 6, manually operable by a lever 1, is automatically tripped open in the event of an overload. The movable contacts 7, 8 are carried by a bimetallic snap-acting plate 9, preferably as shown in Specification 178,103, [Class 38 (v)], and in the closed position are held pressed against fixed contacts 5, 6 by a spur 4 on the lever 1 engaging a detent depression 10 in the plate 9, which also retains the lever 1. Should an overload occur, the current through the plate 9 causes it to heat and snap upwards to open the circuit. This action relieves the pressure between the spur .4 and the detent 10 so that the lever 1 is rotated clockwise by a spring (Fig. 8, not shown) to the '' off " position, and a spring plunger 11 maintains the plate 9 against stops 14 on the base 3. The switch is trip-free of the lever 1, for if the lever is moved back to the " on " position when the plate is bowed upwards, or if the lever 1 is held " on " when the plate snaps upwards, the circuit will still be open. On cooling, the plate 9 snaps down and the switch can then be closed by movement of the lever 1. In an alternative construction (Fig. 9, not shown), a separate heater is provided for the plate 9. In other modifications, the detent 10 is replaced by a protuberance in which case the spur 4 may have a corresponding recess, or the plate 9 may have neither detent nor protuberance in which case the lever is moved over-centre. In a modification, the lever 1 is spring-biassed in the counter-clockwise direction (or the spring may be eliminated) whereby the switch re-closes automatically after occurrence of an overload. The switch shown in Fig. 12 is not trip-free of the lever 1. An additional plate 35 having an aperture to receive the spur 4 and having insulating portions 36, 37 which press against the plate 9, is urged downwardly by shoulders 41 on the lever 1 when the latter is in the " on " position. Should an overload occur and the lever 1 be held in the "on" position, the centre of the plate 9 snaps downwards against the spring plunger 11 and the contacts remain engaged. If the lever is not held, the switch functions as in the previous embodiments. The lever 1 is shaped to closely fit the base 3 so that any arcing tends to be eliminated by the pressure generated inside the base. A luminous signal may be provided on the lever end to show its position in the dark.
